                Toxic Substances Control Act Reporting and Recordkeeping
                Requirements for Perfluoroalkyl and Polyfluoroalkyl Substances
                AGENCY: Environmental Protection Agency (EPA).
                ACTION: Final rule.
                -----------------------------------------------------------------------
                SUMMARY: The Environmental Protection Agency (EPA) is finalizing
                reporting and recordkeeping requirements for per- and polyfluoroalkyl
                substances (PFAS) under the Toxic Substances Control Act (TSCA). In
                accordance with obligations under TSCA, as amended by the National
                Defense Authorization Act for Fiscal Year 2020, EPA is requiring
                persons that manufacture (including import) or have manufactured these
                chemical substances in any year since January 1, 2011, to submit
                information to EPA regarding PFAS uses, production volumes, byproducts,
                disposal, exposures, and existing information on environmental or
                health effects. In addition to fulfilling statutory obligations under
                TSCA, this rule will enable EPA to better characterize the sources and
                quantities of manufactured PFAS in the United States.
                DATES: This final rule is effective on November 13, 2023.

                SUPPLEMENTARY INFORMATION:
                I. Executive Summary
                A. Does this action apply to me?
                 This action may apply to you if you have manufactured (defined by
                statute at 15 U.S.C. 2602(9) to include import) PFAS for a commercial
                purpose at any time since January 1, 2011. The following list of North
                American Industrial Classification System (NAICS) codes is not intended
                to be exhaustive, but rather provides a guide to help readers determine
                whether this document applies to them. Potentially affected entities
                may include:
                 Construction (NAICS code 23);
                 Manufacturing (NAICS code 31 through 33);
                 Wholesale trade (NAICS code 42);
                 Retail trade (NAICS code 44 through 45); and
                 Waste management and remediation services (NAICS code
                562).
                 This list details the types of entities that EPA is aware could
                potentially be regulated by this action. Other types of entities not
                listed could also be regulated. To determine whether your entity is
                regulated by this action, you should carefully examine the
                applicability criteria found in 40 CFR 705.10 and 705.12. If you have
                questions regarding the applicability of this action to a particular
                entity, consult the person listed in the FOR FURTHER INFORMATION
                CONTACT section.
                B. What is the Agency's authority for taking this action?
                 EPA is promulgating this rule pursuant to its authority in TSCA
                section 8(a)(7) (15 U.S.C. 2607(a)(7)). The National Defense
                Authorization Act for Fiscal Year 2020 (FY 2020 NDAA) (Pub. L. 116-92,
                section 7351) amended TSCA section 8(a) in December 2019, adding
                section 8(a)(7), titled ``PFAS Data.'' TSCA section 8(a)(7) requires
                EPA to promulgate a rule ``requiring each person who has manufactured a
                chemical substance that is a [PFAS] in any year since January 1, 2011''
                to report information described in TSCA section 8(a)(2)(A) through (G).
                This includes a broad range of information, such as information related
                to chemical identity and structure, production, use, byproducts,
                exposure, disposal, and health and environmental effects.
                 TSCA section 14 imposes requirements for the assertion,
                substantiation, and review of information that is claimed as
                confidential business information (CBI).
                C. What action is the Agency taking?
                 In this action, EPA is promulgating reporting and recordkeeping
                requirements for entities who have manufactured (including imported) a
                PFAS for commercial purposes at any point since January 1, 2011. This
                rule takes into consideration comments received on the proposed rule
                (86 FR 33926, June 28, 2021 (FRL-10017-78)) input from the Small
                Business Advocacy Review (SBAR) Panel that was convened following
                publication of the proposed rule, and comments received on the SBAR
                Panel Report and Initial Regulatory Flexibility Analysis (IRFA), which
                EPA published with a Notice of Data Availability (NODA) (Ref. 1).
                Details on the final rule requirements, including modifications from
                the proposal, are explained in Unit III.
                 EPA is finalizing this rule both to fulfill its obligations under
                TSCA section 8(a)(7), as amended by the FY 2020 NDAA, and to create a
                more comprehensive database of previously manufactured PFAS to improve
                the Agency's understanding of PFAS in commerce and to support actions
                to address PFAS exposure and contamination.
                D. Why is the Agency taking this action?
                 TSCA section 8(a)(7) requires EPA to promulgate a rule requiring
                each person who has manufactured a PFAS in any year since January 1,
                2011, to report certain information for each year since January 1,
                2011.
                E. What are the incremental economic impacts?
                 EPA has evaluated the costs and benefits of this rulemaking and
                provided an Economic Analysis of the potential impacts associated with
                this rule (Ref. 2). The primary benefit of this rule is providing EPA
                with data on PFAS which have been manufactured, including imported, for
                commercial purposes since 2011; the Agency is not currently aware of
                any similar source of information for these substances of interest.
                Subsequently, EPA will use these data to support activities addressing
                PFAS under TSCA, as well as activities and programs under other
                environmental statutes. The additional data on the production, use,
                exposure, and environmental and health effects of PFAS in the United
                States may allow EPA to more effectively determine whether additional
                risk assessment and management measures are needed. This information
                may lead to reduced costs of risk-based decision making and improved
                decisions concerning PFAS.
                 EPA has evaluated the potential costs of this reporting and
                recordkeeping requirement for manufacturers and article importers.
                Since the notice of proposed rulemaking for this action
                [[Page 70517]]
                published on June 28, 2021 (86 FR 33926 (FRL-10017-78)), EPA found
                additional data and received feedback via public comments to update its
                economic analysis, including estimating the number of PFAS article
                importers. EPA revised cost estimates from $10.8 million in industry
                costs detailed in the draft Economic Analysis for the proposed rule to
                $876 million detailed in the IRFA and NODA (Ref. 1), to $843 million
                using a 3 percent discount rate and $800 million using a 7 percent
                discount rate at the final rule stage. The final Economic Analysis
                (Ref. 2), which is available in the docket, is briefly summarized here.
                The regulated community is expected to incur one-time burdens and costs
                associated with rule familiarization, compliance determination, form
                completion, CBI claim substantiation, recordkeeping, and electronic
                reporting activities. Industry is estimated to incur a burden of
                approximately 11.6 million hours, with a cost of approximately $843
                million and $800 million under a 3 percent and 7 percent discount rate,
                respectively. The Agency is expected to incur a cost of $1.6 million.
                The total social cost is therefore estimated to be approximately $844.8
                million and $801.7 million under a 3 percent and 7 percent discount
                rate, respectively.
                II. Background
                A. What are PFAS?
                 PFAS are a group of synthetic chemicals that have been in use since
                the 1940s and can be found in a wide array of industrial and consumer
                products (Refs. 2 and 3). PFAS are synthesized for many different uses,
                ranging from firefighting foams to coatings for clothes and furniture,
                to food contact substances, to the manufacture of other chemicals and
                products. They are used in a wide variety of products, including
                textiles, electronics, wires and cables, pipes, cooking and bakeware,
                sport articles, automotive products, toys, transportation equipment,
                and musical instruments, which may be imported into the United States
                as finished articles (Ref. 2). PFAS can be released to the environment
                throughout the lifecycle of manufacturing, processing, distribution,
                use, and disposal (Refs. 3 and 4). There is evidence that exposure to
                some PFAS in the environment may be linked to harmful health effects in
                humans and animals, and that continued exposure above specific levels
                to certain PFAS may lead to adverse health effects (Refs. 2, 3, and 4).
                B. What is TSCA section 8(a)(7)?
                 On December 20, 2019, the National Defense Authorization Act for
                Fiscal Year 2020 (NDAA) was signed into law (Pub. L. 116-92). Among
                other provisions, section 7321 of NDAA added TSCA section 8(a)(7) which
                states that the Administrator shall promulgate a rule in accordance
                with this subsection requiring each person who has manufactured a
                chemical substance that is a perfluoroalkyl or polyfluoroalkyl
                substance (PFAS) in any year since January 1, 2011, to submit to the
                Administrator a report that includes, for each year since January 1,
                2011, the information described in subparagraphs (A) through (G) of
                paragraph (2). The categories of information described in sections
                8(a)(2)(A) through (G) are:
                 The common or trade name, chemical identity and molecular
                structure of each chemical substance or mixture for which a report is
                required;
                 Categories or proposed categories of use for each
                substance or mixture;
                 Total amount of each substance or mixture manufactured or
                processed, the amounts manufactured or processed for each category of
                use, and reasonable estimates of the respective proposed amounts;
                 Descriptions of byproducts resulting from the manufacture,
                processing, use, or disposal of each substance or mixture;
                 All existing information concerning the environmental and
                health effects of each substance or mixture;
                 The number of individuals exposed, and reasonable
                estimates on the number of individuals who will be exposed, to each
                substance or mixture in their places of work and the duration of their
                exposure; and
                 The manner or method of disposal of each substance or
                mixture, and any change in such manner or method.
                 Finally, in carrying out TSCA section 8, section 8(a)(5) requires
                EPA, to the extent feasible, to (A) not require unnecessary or
                duplicative reporting, (B) minimize compliance costs on small
                manufacturers and processors, and (C) apply any reporting obligations
                to those persons likely to have information relevant to effective
                implementation of TSCA.
                C. What did EPA propose?
                 In the proposed rule, EPA published for the reporting and
                recordkeeping requirements for PFAS manufacturers under TSCA section
                8(a)(7). EPA proposed to require any entity who had commercially
                manufactured a PFAS that is a TSCA chemical substance at any time since
                January 1, 2011, to electronically report certain information to EPA
                regarding PFAS identity, production volumes, industrial uses,
                commercial and consumer uses, byproducts, worker exposure, disposal,
                and any existing information related to environmental and health
                effects. Such information would be reported for each year since 2011 in
                which a covered PFAS was manufactured, to the extent such information
                were known to or reasonably ascertainable by the reporter. EPA also
                proposed a five-year recordkeeping period following the submission
                date.
                 EPA also proposed the following structural definition of PFAS: per-
                and polyfluorinated substances that structurally contain the unit R-
                (CF2)-C(F)(R')R''. Both the CF2 and CF moieties
                are saturated carbons and none of the R groups (R, R', or R'') can be
                hydrogen. Under the proposal, reporting would have been required for
                any TSCA chemical substance (including any mixture with a chemical
                substance) which met the proposed structural definition and had been
                manufactured for a commercial purpose at any time since January 1,
                2011.
                 EPA did not propose any reporting exemptions or production volume
                thresholds. The scope of covered chemical substances under the proposed
                rule included any amounts of PFAS which were known to or reasonably
                ascertainable by the manufacturer, including PFAS-containing articles,
                byproducts, and impurities. EPA also did not propose any exemptions or
                flexibilities for small manufacturers.
                 EPA proposed a six-month information collection period following
                the effective date of the final rule, after which the reporting tool
                would open for a six-month reporting period. Thus, the proposed rule
                stipulated a reporting deadline one year from the effective date of the
                final rule.
                III. Final PFAS Reporting and Recordkeeping Requirements
                 In this unit, EPA discusses in detail the final reporting and
                recordkeeping requirements, including changes from the proposed rule in
                response to public input.
                A. What substances are covered by this rule?
                1. The Scope of PFAS for the Purpose of This Rule
                 Under TSCA section 8(a)(7), EPA must collect information on
                chemical substances manufactured (including imported) for commercial
                purposes, including chemical substances present in a mixture, that are
                ``perfluoroalkyl or
                [[Page 70518]]
                polyfluoroalkyl substances,'' or PFAS. TSCA section 8(a)(7) does not
                define or characterize ``PFAS.'' EPA has determined that any TSCA
                chemical substance (as that term is defined by TSCA section 3(2); see
                Unit IV.A.2.) that falls within the structural definition at 40 CFR
                705.3 is subject to reporting under TSCA section 8(a)(7), if it has
                been manufactured for commercial purposes in any year since January 1,
                2011. The proposed definition defined PFAS as a substance that includes
                the following structure: R-(CF2)-C(F)(R')R'', in which both
                the CF2 and CF moieties are saturated carbons and none of
                the R groups (R, R' or R'') can be hydrogen. EPA found that at least
                1,364 substances from both the TSCA Inventory (Inventory) and Low-
                Volume Exemption (LVE) claims would meet the proposed structural
                definition. Separately, a count of chemicals meeting the proposed
                definition on EPA's CompTox Chemicals Dashboard (Ref. 6) found
                approximately 9,400 structures, though many of those structures are not
                known TSCA chemical substances and would be out of scope of reporting
                for this rule, as explained in section III.A.2 of this rule.
                 EPA determined that a structural definition was more appropriate
                for this rule than a discrete list of specifically identified
                substances. Other TSCA requirements have relied on a structural
                definition when appropriate (e.g., the long-chain perfluoroalkyl
                carboxylate (LCPFAC) significant new use rule (SNUR) defines covered
                substances using a structural definition (40 CFR 721.10536) (Ref. 7),
                and the polymer exemption rule for new chemical pre-manufacture notices
                (PMNs) defines covered PFAS polymers using structural definitions (40
                CFR 723.250)). Additionally, other scientific and regulatory bodies,
                such as the Organization of Economic Cooperation and Development (OECD)
                (Refs. 8 and 9), have defined PFAS using various structural
                definitions. Thus, there is clear precedent for using a structural
                definition both for TSCA rules and for actions addressing PFAS, and a
                structural definition is consistent with the text of TSCA section
                8(a)(7). EPA also determined that limiting the scope of reporting to a
                discrete list of chemicals would eliminate reporting on substances of
                interest to the Agency. Given various reporting exemptions for both
                existing chemicals (e.g., certain byproducts and research and
                development (R&D) substances are exempt from reporting in the Chemical
                Data Reporting (CDR) rule) and new chemicals (e.g., byproducts and
                impurities that are not listed on the Inventory), and with minimum
                reporting thresholds under other rules, EPA may be unaware of some TSCA
                chemical substances which meet this structural definition of PFAS.
                Providing a discrete list based on substances currently on the
                Inventory and in LVEs likely limits EPA's ability to capture all
                substances that meet the structural definition, and which may present
                properties similar to perfluorooctanoic acid (PFOA), perfluorooctane
                sulfonic acid (PFOS), and hexafluoropropylene oxide dimer acid (HFPO-
                DA) and its ammonium salt (popularly known as ``GenX''). Therefore, EPA
                is defining PFAS for this TSCA section 8(a)(7) rule using a structural
                definition to avoid inadvertently limiting the scope of reporting to
                substances on a discrete list.
                 After reviewing public comments, EPA determined that the proposed
                definition may not include all substances for which EPA believes
                reporting of information is necessary (see additional discussion of
                relevant public comment in Unit IV.A). Therefore, EPA is modifying the
                definition of PFAS from the proposal. For the purpose of this TSCA
                section 8(a)(7) reporting rule, EPA is defining ``PFAS'' using a
                structural definition. PFAS is defined as including at least one of
                these three structures:
                 R-(CF2)-CF(R')R'', where both the
                CF2 and CF moieties are saturated carbons;
                 R-CF2OCF2-R', where R and R' can
                either be F, O, or saturated carbons; and
                 CF3C(CF3)R'R'', where R' and R'' can
                either be F or saturated carbons.
                 Manufacturers of substances that do not meet this structural
                definition are not required to report under this rule. EPA is providing
                a list of substances that meet this definition, gathered from the
                Inventory, LVEs, and the CompTox Chemicals Dashboard; this list will be
                available in the CompTox Chemicals Dashboard at https://comptox.epa.gov/dashboard. A substance that is not on this list but
                still falls under the definition of a ``chemical substance'' under TSCA
                (see Unit III.A.2) is subject to this rule if the substance has been
                manufactured for a commercial purpose since 2011.
                 EPA is modifying the proposed definition first to remove the R
                group requirements, resulting in the first sub-structure of this rule's
                definition of PFAS (i.e., R-(CF2)-CF(R')R'', where both the
                CF2 and CF moieties are saturated carbons). The removal of
                the R group requirements from the proposed definition will expand the
                universe of PFAS to include additional substances of potential concern
                because they are likely to be persistent. While the proposed definition
                was developed to focus on substances most likely to be persistent in
                the environment while excluding those substances that are ``lightly''
                fluorinated (i.e., the molecule only contains unconnected
                CF2 or CF3 moieties), EPA acknowledges that
                substances that are not fully fluorinated may still be persistent in
                the environment. This is because the persistence of organofluoro
                compounds is more related to the density of C-F bonds within the
                molecule than simply the existence of fully fluorinated carbons (Ref.
                10). The final definition, which does not include the proposed
                definition's R group requirements focuses the definition on those
                substances most likely to persist in the environment. The final
                definition does not include substances that only have a single
                fluorinated carbon, or unsaturated fluorinated moieties (e.g.,
                fluorinated aromatic rings and olefins). The latter set of substances
                are more susceptible to chemical transformation than their saturated
                counterparts, and therefore, are less likely to persist in the
                environment (Ref. 10). EPA has determined that, for the purpose of this
                rule, it is unnecessary to extend reporting requirements to substances
                that only have a single fluorinated carbon or unsaturated fluorinated
                moieties and are therefore less likely to persist in the environment,
                unlike substances like PFOA, PFOS, and GenX.
                 In addition to modifying the proposed definition by removing the R
                group requirements, EPA determined that the definition should be
                further expanded by adding two sub-structures that will include certain
                substances of interest to the Agency and to public commenters.
                Furthermore, the additional two sub-structures will encompass other
                chemical substances that are persistent in the environment but were not
                covered by the proposed definition. The second sub-structure (R-
                CF2OCF2-R', where R and R' can either be F, O, or
                saturated carbons) aims to capture certain fluorinated ethers. EPA
                believes that these ethers are likely to be found in water; for
                example, perfluoro-2-methoxyacetic acid (PFMOAA) (Chemical Abstracts
                Service Registry Number (CASRN) 674-13-5) and other chemicals with
                structures similar to GenX found in the Cape Fear River. However, they
                may not have been reported to the Inventory or as an LVE, and therefore
                would not have been considered when developing the proposed definition,
                which focused on substances in the known TSCA universe
                [[Page 70519]]
                (i.e., the Inventory and LVEs). Additionally, it is possible that such
                substances are not on the Inventory due to TSCA reporting exemptions
                (e.g., byproducts, or certain R&D substances). Based on these ethers'
                properties and the lack of prior TSCA reporting, EPA believes that data
                related to the manufacturing of these PFAS is necessary to carry out
                TSCA section 8(a)(7) and would not be duplicative of other reporting.
                Thus, EPA is interested in known or reasonably ascertainable
                information on substances meeting this sub-structure definition, as it
                meets EPA's threshold of focusing on chemicals more likely to exhibit
                properties similar to GenX (along with PFOA and PFOS), including their
                likely presence in the environment.
                 Finally, the third sub-structure
                (CF3C(CF3)R'R'', where R' and R'' can either be F
                or saturated carbons) aims to capture a different type of branching for
                highly fluorinated substances that would not meet the proposed
                definition due to their non-adjacent fluorinated carbons. These
                substances are likely to be persistent, and EPA believes that reporting
                for these more branched substances is necessary to collect the
                information described in TSCA section 8(a)(2)(A)-(G) for substances
                with similar persistence properties as PFOA, PFOS, or GenX. For
                instance, 4,4,4-Trifluoro-2,2,3,3-tetra)kis(trifluoromethyl)butanoic
                acid (CASRN 1882109-62-7) would not have met the proposed definition
                due to its non-adjacent fluorinated carbons, but it has the same number
                of carbon, fluorine, and oxygen atoms as PFOA, and has been identified
                as an isomer of PFOA under the Stockholm Convention (Ref. 11). Further,
                this substance, like other substances meeting this sub-structure, has
                many highly fluorinated moieties such that EPA believes it is likely to
                be persistent in the environment. EPA is interested in known or
                reasonably ascertainable information on substances meeting this sub-
                structure definition, as these chemicals are likely to persist in
                environments to which they are released.
                 Under this rule's definition of PFAS, EPA identified additional
                substances that may be subject to the rule from the Inventory and LVEs,
                i.e., ``known TSCA chemical substances.'' Specifically, EPA identified
                an additional 22 chemical substances on the Inventory and 19 LVEs, all
                of which are now covered under the first sub-structure of this rule's
                definition. To date, EPA has not identified any additional substances
                on the Inventory or as an LVE under the second and third sub-
                structures. This relatively modest increase of 41 known TSCA chemical
                substances would bring the known universe of TSCA chemical substances
                meeting this rule's definition of PFAS to 1,462, from 1,364 known TSCA
                PFAS identified by the proposed definition. However, as discussed
                previously, a substance's absence on the Inventory or LVEs may be due,
                at least in part, to several exemptions for Inventory and new chemicals
                reporting (e.g., byproducts, impurities, certain R&D substances). In
                the absence of those exemptions, a PFAS meeting the definition under
                TSCA section 3(2) may be subject to reporting under this rule.
                 EPA is also affirming that fluoropolymers which meet this rule's
                definition of PFAS are reportable under this rule; this includes higher
                molecular weight fluoropolymers. EPA does not believe the requested
                data on fluoropolymers would be considered duplicative or unnecessary:
                this information is not reported to EPA otherwise, and any
                manufacturers' existing information on such fluoropolymers will inform
                EPA's understanding of such types of PFAS within U.S. commerce,
                including their downstream uses and their disposal methods.
                 EPA notes that this definition may not be identical to other
                definitions of PFAS used within EPA and/or by other organizations. The
                term ``PFAS'' has been used broadly by many organizations for their
                individual research and/or regulatory needs. Various programs or
                organizations have distinct needs or purposes apart from this TSCA
                section 8(a)(7) reporting rule, and therefore, different definitions of
                the term ``PFAS'' may be appropriate for other purposes. The Agency
                notes that this perspective, that different users may have very
                different needs and no single PFAS characterization or definition meets
                all needs, is shared by many other organizations, including OECD (see
                page 29, Ref. 8). EPA has determined the final definition of ``PFAS''
                is the most appropriate definition for this TSCA section 8(a)(7) rule
                and acknowledges that there may be other rules or programs who apply
                different definitions to meet their own needs.
                2. Definition of ``Chemical Substance'' Under TSCA and PFAS in Mixtures
                 This rule is limited to manufacturers (including importers) of PFAS
                that are considered a ``chemical substance.'' Under TSCA section 3(2),
                ``chemical substance'' means any organic or inorganic substance of a
                particular molecular identity, including: (1) Any combination of such
                substances occurring in whole or in part as a result of a chemical
                reaction or occurring in nature, and (2) Any element or uncombined
                radical. This rule does not require reporting on activities that are
                excluded from the definition of ``chemical substance'' in TSCA section
                3(2)(B).
                 Even though the definition of chemical substance excludes mixtures,
                PFAS as a chemical substance may be present in a mixture. Therefore,
                this rule requires reporting on each chemical substance that is a PFAS,
                including as a component of a mixture. This rule does not require
                reporting on components of a mixture that do not fall under the
                structural definition of PFAS, as explained in Unit III.A.1.
                B. Which entities are covered by this rule?
                1. Scope of Covered Entities
                 Anyone who has manufactured (including imported) a PFAS for a
                commercial purpose in any year since January 1, 2011, is covered by
                this rule. As noted in Unit III.B.2, ``manufacture for a commercial
                purpose'' includes the coincidental manufacture of PFAS as byproducts
                or impurities. EPA believes at least portions of the NAICS codes listed
                in Unit I.A. may be covered by this rule. This rule extends to
                manufacturers (including importers) only. Importers of PFAS in articles
                are considered PFAS manufacturers.
                 Persons who have only processed, distributed in commerce, used,
                and/or disposed of PFAS are not required to report under this rule,
                unless they also have manufactured PFAS for a commercial purpose. If an
                entity (such as a wastewater treatment plant) is simply processing PFAS
                they received domestically, and not also manufacturing PFAS, including
                as a byproduct, then the entity is not covered by this rule. Although
                EPA received several public comments about extending the rule to cover
                processors (see Unit IV.), TSCA section 8(a)(7) only refers to
                manufacturers and expanding the rule to processors would be pursuant to
                EPA's separate rulemaking authority at TSCA section 8(a)(1), which the
                Agency is not pursuing at this time.
                2. Scope of ``Manufacture for Commercial Purposes''
                 Pursuant to TSCA section 8(f), the scope of ``manufacturing'' for
                the purposes of this rule is limited to entities manufacturing for a
                commercial purpose. EPA is defining ``manufacture for commercial
                purposes'' to align with definitions used in other rules. Specifically,
                ``manufacture for
                [[Page 70520]]
                commercial purposes'' includes the import, production, or manufacturing
                of a chemical substance or mixture containing a chemical substance with
                the purpose of obtaining an immediate or eventual commercial advantage
                for the manufacturer. This includes, but is not limited to, the
                manufacture of chemical substances or mixtures for commercial
                distribution, including test marketing, or for use by the manufacturer
                itself as an intermediate or for product research and development.
                ``Manufacture for commercial purposes'' also includes the coincidental
                manufacture of byproducts and impurities that are produced during the
                manufacture, processing, use, or disposal of another chemical substance
                or mixture. As described in Unit III.B.1, simply receiving PFAS from
                domestic suppliers or other domestic sources is not, in itself,
                considered manufacturing PFAS for commercial purposes. Entities that
                process and/or use PFAS only need to report on PFAS they have
                manufactured (including imported), if any.
                 However, certain activities are not considered ``manufacture for
                commercial purposes'' under TSCA section 8(f) (e.g., non-commercial R&D
                activities such as scientific experimentation, research, or analysis
                conducted by academic, government, or independent not-for-profit
                research organizations, unless the activity is for eventual commercial
                purposes) and are not subject to the reporting requirements in this
                rule. For example, reporting would not be required for a Federal agency
                which manufactures or imports PFAS when it is not for any immediate or
                eventual commercial advantage.
                3. Non-Reportable Activities
                 As discussed in Unit III.B.2, entities who have manufactured PFAS
                for a commercial purpose include those who have imported PFAS
                (including in wastes), or those who have coincidentally produced PFAS
                during the manufacture, processing, use, or disposal of another
                chemical substance or mixture. EPA noted in the proposed rule that this
                may include certain waste management companies, if they have imported
                PFAS in a waste or produced PFAS at their site during the disposal of
                another chemical substance or mixture. Through public comments and
                input during the SBAR Panel, EPA understands that entities engaged in
                certain waste management activities are in the unique position of not
                having knowledge of PFAS they may have manufactured for commercial
                purposes. Entities that import municipal solid wastes (MSW) for the
                purpose of disposal or destruction cannot know or reasonably ascertain
                that they imported PFAS in the MSW streams. MSW streams are
                heterogeneous and generally difficult to characterize, in the absence
                of notification or labeling requirements related to the content of the
                waste. There were no Federal labeling or notification requirements for
                PFAS in wastes concurrent with this reporting period, nor are there
                general labeling practices for PFAS in MSW streams that are sent for
                disposal or destruction. Additionally, standard analytical methods for
                PFAS in MSW streams were not available during this reporting period.
                Because no PFAS was listed as a hazardous waste and subject to
                notification requirements under the Resource Conservation and Recovery
                Act (RCRA) or other Federal laws during this rule's lookback period
                (i.e., since January 1, 2011), and due to general industry practices,
                EPA understands that importers of MSW streams for disposal or
                destruction would not have any records or data that they had imported
                PFAS or any other information relevant to TSCA section 8(a)(7).
                Therefore, EPA has determined that waste management activities
                involving importing municipal solid waste streams for the purpose of
                disposal or destruction are not within scope of this rule's reporting
                requirements, per EPA's obligations under TSCA section 8(a)(5)(C).
                 However, EPA is not broadly exempting all waste management
                facilities from this rule. Facilities that have imported waste
                containing PFAS, other than in MSW streams for destruction or disposal,
                are likely to have information relevant to this rule. Other waste
                management sites may have relevant information regarding PFAS contents
                in waste they have imported outside of MSW, or for the purpose of
                recycle or reuse; thus, EPA is required to apply reporting requirements
                to such entities who may have relevant information, pursuant to TSCA
                section 8(a)(5)(C). This would include waste management sites who
                import PFAS-containing waste (including in MSW) for the purpose of
                recycling or reuse for PFAS-containing products, as well as waste
                management sites who import PFAS in wastes that are not municipal solid
                waste streams. In the former activity, entities who import wastes that
                may contain PFAS, such as some carpets and rugs, for the purpose of
                recycling or reusing the PFAS-containing material, may be aware of the
                general nature of those materials and the downstream processing and use
                information that is responsive to this rule (see Table 14, Ref. 12). In
                the latter activity, importers of PFAS-containing wastes that are not
                MSW (such as industrial wastes) may also have knowledge of the contents
                of the waste they have imported due to labeling or notification
                practices, including under international agreements affecting
                transboundary movement of wastes (Ref. 13). Because certain importers
                of waste (besides MSW that is imported for the purpose of disposal or
                destruction) are anticipated to know or reasonably ascertain that they
                have manufactured PFAS, EPA is extending reporting requirements to
                manufacturers (including importers) of PFAS in wastes, unless they have
                imported PFAS in municipal solid waste streams for the purpose of
                disposal or destruction.
                C. What is the reporting standard of this rule?
                 For the purpose of this rule, the reporting standard is information
                known to or reasonably ascertainable by the manufacturer, which is the
                standard used in other TSCA section 8 rules, including CDR since 2011
                (see TSCA section 8(a)(2)). ``Known to or reasonably ascertainable by''
                is defined to include ``all information in a person's possession or
                control, plus all information that a reasonable person similarly
                situated might be expected to possess, control, or know'' (40 CFR
                704.3). This reporting standard requires reporting entities to evaluate
                their current level of knowledge of their manufactured products
                (including imports), as well as evaluate whether there is additional
                information that a reasonable person, similarly situated, would be
                expected to know, possess, or control. This standard carries with it an
                exercise of due diligence, and the information-gathering activities
                that may be necessary for manufacturers to achieve this reporting
                standard may vary from case-to-case.
                 This standard would require that submitters conduct a reasonable
                inquiry within the full scope of their organization (not just the
                information known to managerial or supervisory employees). This
                standard may also entail inquiries outside the organization to fill
                gaps in the submitter's knowledge. Such activities may, though not
                necessarily, include phone calls or email inquiries to upstream
                suppliers or downstream users or employees or other agents of the
                manufacturer, including persons involved in the research and
                development, import or production, or marketing of the PFAS. Examples
                of types of information that are considered to be in a manufacturer's
                possession or
                [[Page 70521]]
                control, or that a reasonable person similarly situated might be
                expected to possess, control, or know include: files maintained by the
                manufacturer such as marketing studies, sales reports, or customer
                surveys; information contained in standard references showing use
                information or concentrations of chemical substances in mixtures, such
                as a Safety Data Sheet (SDS) or a supplier notification; and
                information from the CAS or from Dun & Bradstreet (D-U-N-S). However,
                if particular information cannot be derived or reasonably estimated
                without conducting further customer surveys (i.e., without sending a
                comprehensive set of identical questions to multiple customers), it
                would not be ``reasonably ascertainable'' to the submitter. Thus, there
                is not a need to conduct new surveys for purposes of this rule. As
                described previously, however, existing survey data may nevertheless be
                ``known to'' the organization. This information may also include
                documented knowledge gained through discussions, conferences, and
                technical publications. In addition, this is the same reporting
                standard employed in the TSCA section 8(a) CDR rule (40 CFR 711.15). In
                response to public comments and input received through the SBAR Panel,
                EPA has also created additional compliance guidance related to this
                reporting standard, including for small entities and for article
                importers (Ref. 14). Therefore, EPA anticipates many reporters under
                this rule are familiar with this reporting standard, and resources are
                available to support those reporters who may not be familiar with the
                standard.
                 In the event that a manufacturer (including importer) does not have
                actual data (e.g., measurements or monitoring data) to report to EPA,
                the manufacturer (including importer) should consider whether
                ``reasonable estimates'' of such information are ascertainable.
                ``Reasonable estimates'' may rely, for example, on approaches such as
                mass balance calculations, emissions factors, or best engineering
                judgment. EPA notes that many of the data elements requested under this
                rule, including production volumes or environmental release volumes,
                incorporate a level of estimation by requiring only two significant
                figures. Other data elements, including worker exposure, are reported
                as ranges, as with CDR. For instance, a manufacturer may be able to
                estimate the range of number of workers reasonably likely to be exposed
                for each commercial use based on the manufacturer's knowledge of the
                commercial sites' sizes, without specific workplace monitoring data;
                the manufacturer, would report the estimated range, rather than
                reporting that the information is not known. In general, EPA believes
                that industry possesses a greater knowledge than EPA about its own
                supply chain and operations related to the chemical substances it
                manufactures and the downstream uses, even if they do not control their
                customers' sites. However, if manufacturers do not know nor can
                reasonably make estimates for certain data elements, except for
                production volumes, they may indicate such information is ``Not Known
                or Reasonably Ascertainable'' (NKRA) to them in lieu of the requested
                estimate or range. For instance, if a manufacturer does not know and
                cannot reasonably ascertain (including, having no basis for a
                reasonable estimate or assumption based on past experiences for the
                same or similar substances) how a PFAS is disposed of as a waste in a
                given year, the manufacturer may submit ``NKRA'' for that information.
                Reporters are also advised that ``NKRA'' designations cannot be claimed
                as CBI under TSCA section 14. Reporting NKRA should only happen when
                data are truly not reasonably ascertainable or are unattainable (e.g.,
                when the appropriate recordkeeping period has lapsed and a past record
                is no longer available).
                 EPA has published reporting instructions and a Small Entity
                Compliance Guide, which include information related to this reporting
                standard and the activities that small entities, including article
                importers, may take to meet the due diligence requirement (Ref. 14).
                 If, after conducting due diligence and reviewing known or
                reasonably ascertainable existing information, a manufacturer,
                particularly an importer of articles containing PFAS, may not have
                knowledge that they have manufactured or imported PFAS and thus need
                not report under this rule. EPA encourages such an entity to document
                its activities to provide evidence of due diligence. Additionally,
                consistent with their own business practices, companies may elect to
                retain documentation of their conclusion that they were not subject to
                reporting requirements.
                D. What information must be reported under this rule?
                1. General Reporting Form
                 EPA is requiring that PFAS manufacturers submit the following
                information for each PFAS, for each year in which that substance was
                manufactured since January 1, 2011, to the extent the information is
                known or reasonably ascertainable. For the purposes of this rule, EPA
                is requiring this information to be submitted for each chemical
                substance that is a PFAS. For mixtures that contain at least one
                chemical substance that is a PFAS, manufacturers must submit
                information for each chemical substance in the mixture that is a PFAS.
                For example, a mixture comprised of PFAS A and PFAS B would result in
                the submission of two forms containing the information described later
                in this unit for each PFAS. For chemical substances of unknown or
                variable compositions, complex reaction products, and biological
                materials (UVCBs), including polymers, a single form may be submitted
                for that UVCB. EPA encourages submitters of mixtures and UVCBs that
                contain PFAS to provide additional information in the optional free
                text box related to the composition of that mixture or UVCB at the time
                of manufacture, if known.
                 EPA is largely finalizing the proposed reporting requirements, with
                a few modifications based on public comments. Changes to the proposed
                requirements include: removing the requirements for reporting maximum
                production volume in the first 12 months and maximum yearly production
                volume in any 3 years; removing the requirement for reporting the
                maximum quantity on-site at any time (including storage); modifying the
                requirement to submit the molecular structure for each substance by
                making the submission optional for any Class 1 chemical substance on
                the Inventory (but required for all others); requiring submitters to
                provide a generic name or description (which indicates, at least, that
                the substance is fluorinated) in lieu of the specific chemical identity
                or trade name when neither are known; reporting analytical methods, if
                any; adding optional comment boxes to provide any additional
                information or clarification to EPA.
                 A spreadsheet containing the reporting requirements is also
                available in the docket (Ref. 15).
                2. Streamlined Reporting Form Option for Article Importers
                 Article importers are not exempt from this rule. Given the
                reporting exemptions in other TSCA reporting rules, exempting imported
                articles from the scope of this TSCA section 8(a)(7) reporting rule
                would perpetuate data gaps in EPA's level of knowledge related to PFAS
                manufactured for a commercial purpose since 2011. EPA cannot know what
                requested information is ``reasonably ascertainable'' to all article
                [[Page 70522]]
                importers without knowing the full range of potentially available
                information to be reported. Thus, EPA does not otherwise have the
                information outlined in TSCA section 8(a)(7) on PFAS within imported
                articles, and the Agency cannot justify a broad exemption of imported
                articles under TSCA section 8(a)(5)(A), which requires EPA, to the
                extent feasible, to not require unnecessary or duplicative reporting.
                However, after considering public input on the information that may be
                known to or reasonably ascertainable by some PFAS article importers,
                EPA is finalizing a reporting option for article importers to provide
                data to EPA on a streamlined form, if they do not know or cannot
                reasonably ascertain information requested on the longer standard form
                described in Unit III.D.1.
                 If an article importer determines they have imported a covered
                substance in an article, they would have the option to provide
                information to EPA through the streamlined form. The information
                requested through this streamlined form would still include chemical
                identity, processing and use information, and production volume, as
                well as the option to provide any additional information to EPA that
                the entity may have (e.g., SDS, disposal information).
                 The production volume requested is the volume of the imported
                article, rather than the PFAS. EPA believes it is more likely that an
                article importer is able to determine the total imported production
                volume of articles rather than the volume related to just the PFAS
                contained within the article. For instance, an article importer may
                submit as the production volume the total weight of the PFAS-containing
                imported articles (e.g., in tons or pounds). Alternatively, the article
                importer could report the production volume in terms of quantity of the
                article imported (e.g., number of vehicles). The reporter would also be
                required to specify the unit of measurement reflected in the imported
                production volume. Based on information provided from article importers
                during the public comment period and the SBAR Panel, EPA believes that
                many article importers would have more difficulty providing precise
                production volumes of just the PFAS within an article. Industry input
                indicated that the historical documentation provided to article
                importers would not always or reliably include the weight or
                concentration of a PFAS contained in the article, making it more
                difficult for article importers to precisely calculate the production
                volume of just the PFAS contained within the article. Based on public
                input on the historical reporting practices and knowledge of PFAS in
                imported articles, and the fact that this rule is not a product testing
                requirement, EPA believes that article importers are more easily able
                to determine the imported production volume of the article itself. EPA
                acknowledges that it would be preferable to have the production volume
                of the chemical itself, though having the production volume of the
                imported article would still confer meaningful information to EPA for
                the purpose of chemical assessments under TSCA and other programs.
                Because EPA would rather have data on the production volume of the
                imported article, rather than many ``NKRA'' responses related to the
                production volume of the PFAS itself, EPA is requiring article
                importers to submit the production volume information on the whole
                article rather than the PFAS contained within the article.
                 The streamlined article importer form would require the following
                information to the extent it is known or reasonably ascertainable:
                 1. Chemical identity:
                 a. Specific chemical name, or
                 b. Generic name(s) or description(s) if the specific chemical
                name(s) is claimed as CBI and/or when a manufacturer knows they have a
                PFAS but is unaware of its specific chemical identity. A generic name
                must meet the naming requirements for this rule and indicate the
                substance is a fluorinated substance (i.e., contain ``fluor'').
                 2. Chemical identification number:
                 a. CASRN, or
                 b. Accession or LVE case number, if applicable, and if the specific
                CASRN is unknown. EPA notes that this rule does not require
                manufacturers to obtain a CASRN or other identifier for a substance
                without such a number for the purpose of complying with this rule.
                 3. Trade name or common name, if applicable.
                 4. Representative molecular structure, for any PFAS that is not a
                Class 1 substance on the Inventory. And optional free text for further
                clarification on the chemical identity or molecular structure (such as
                for Class 2 substances, or where the molecular structure is of unknown
                or variable composition).
                 5. Import production volume of the imported article and the unit of
                measurement for that production volume (e.g., quantity of the imported
                article, pounds, tons).
                 6. Industrial processing and use:
                 a. Type of process or use;
                 b. Sector(s);
                 c. Functional use category(ies); and
                 d. Percent of production volume for each use.
                 7. Consumer and commercial use:
                 a. indicator for whether this is a consumer and/or commercial
                product;
                 b. Product category;
                 c. Functional use category(ies);
                 d. Percent production volume for each use;
                 e. Maximum concentration in any product;
                 f. Indicator for use in products intended for children;
                 g. Indicator for imported but never physically at site; and
                 h. Any optional information the article importer wishes to provide.
                 Under TSCA section 8(a)(5)(C), EPA must, to the extent feasible,
                ``apply any reporting obligations to those persons likely to have
                information relevant to the effective implementation of [TSCA].'' EPA
                believes that this streamlined reporting form option for any article
                importer would still provide necessary information to EPA under TSCA
                section 8(a)(7), while reducing the reporting burden for the data
                elements that EPA understands may not be known to or reasonably
                ascertainable by article importers. However, to the extent any
                additional information requested on the longer forms is known to or
                reasonably ascertainable by the article importer (e.g., information on
                disposal of that PFAS, or an SDS or other existing information
                regarding environmental or health effects), the reporter would have the
                option and ability to submit that information to EPA through the
                ``optional'' field. EPA also notes that it is possible that a
                manufacturer both imports a PFAS within an article, and otherwise
                manufactures (including imports) the same PFAS beyond an article. In
                such scenarios, the reporter would still have to provide information on
                the longer standard form for the non-imported article and would have
                the option to report on the PFAS within the imported article either on
                the streamlined form or within the longer standard form. The reporting
                tool for this rule will enable multiple form options for the same PFAS
                if appropriate.
                3. Streamlined Reporting Form Option for R&D Substances Manufactured
                Below 10 Kilograms
                 EPA is also including R&D substances that were manufactured,
                including imported, for a commercial purpose within the scope of this
                rule. EPA notes that the scope of ``manufacture for commercial
                purposes'' encompasses any importing, production, or other
                manufacturing activities with the purpose of obtaining an immediate or
                eventual commercial advantage and includes chemicals ``for use by the
                [[Page 70523]]
                manufacturer, including use for product research and development'' (40
                CFR 704.3). R&D substances which meet the scope of ``manufacture for
                commercial purposes'' must be reported under this rule, even if the
                PFAS itself was not later commercialized. However, R&D substances which
                have not been manufactured for commercial purposes (such as for
                scientific experimentation, research, or analysis conducted by
                academic, government, or independent not-for-profit research
                institutions, unless the activity is for eventual commercial purposes)
                would not be within scope of this rule (40 CFR 720.30(i)).
                 EPA believes that the submission of information related to the
                commercial manufacture of PFAS as R&D substances is necessary to
                understand the scope of PFAS manufactured in the United States. With
                existing R&D reporting exemptions under other TSCA rules (including CDR
                and PMN submissions), EPA does not have a dataset of PFAS manufactured
                as R&D substances. Therefore, reporting on such substances is necessary
                to the effective implementation of TSCA. Further, EPA understands that
                manufacturers of R&D substances that have been exempt under other
                reporting rules should have certain documentation available to support
                those exemption claims, in accordance with their recordkeeping
                requirements.
                 However, EPA understands through input from public commenters and
                the SBAR Panel that much of the information requested for this rule is
                unknown and not reasonably ascertainable to manufacturers of R&D
                substances, particularly small entities who may manufacture R&D
                substances in small quantities. EPA believes that manufacturers of R&D
                substances in such low quantities are likely to have manufactured those
                substances purely for laboratory analytical purposes, which may be at
                their own site or their customers' sites. As such, these manufacturers
                are aware of the R&D chemical identity and production volume but are
                unlikely to have any other information requested. However, EPA believes
                that manufacturers of R&D chemicals manufactured in larger quantities
                (i.e., greater than 10 kilograms per year) are more likely to have the
                other information requested, including worker exposure information,
                disposal information, and health or environmental effects information
                (such as monitoring or toxicity data). Given EPA's understanding of
                typical recordkeeping practices of R&D activities, it is likely that a
                manufacturer with greater quantities of R&D substances would know the
                requested information on those substances beyond their identities and
                production volumes. Under TSCA section 8(a)(5)(C), EPA shall, to the
                extent feasible, apply reporting requirements to those persons likely
                to have relevant information. Therefore, EPA is providing another
                streamlined reporting option to manufacturers of R&D substances that
                were manufactured in volumes under 10 kilograms per year, if they do
                not know or cannot reasonably ascertain information requested on the
                longer standard form described in Unit III.D.1.
                 Information requested on this form, for each R&D PFAS manufactured
                below 10 kilograms per year, will include the following to the extent
                it is known or reasonably ascertainable:
                 1. Chemical identity:
                 a. Specific chemical name, or
                 b. Generic name(s) or description(s) if the chemical name(s) is
                claimed as CBI and/or when a manufacturer knows they have a PFAS but is
                unaware of its specific chemical identity. A generic name must meet the
                naming requirements for this rule and indicate the substance is a
                fluorinated substance (i.e., contain ``fluor'').
                 2. Chemical identification number:
                 a. CASRN, or
                 b. TSCA Accession Number or LVE case number, if applicable, and if
                the specific CASRN is unknown. EPA notes that this rule does not
                require manufacturers to obtain a CASRN or other identifier for a
                substance without such a number for the purpose of complying with this
                rule.
                 3. Trade name or common name, if applicable.
                 4. Representative molecular structure, for any PFAS that is not a
                Class 1 substance on the Inventory. With optional free text for further
                clarification on the chemical identity or molecular structure (such as
                for Class 2 substances, or where the molecular structure is of unknown
                or variable composition).
                 5. Production volume:
                 a. Domestically manufactured.
                 b. Imported.
                 6. Indicator for imported but never physically at site.
                 7. Any optional information the manufacturer wishes to provide.
                 EPA believes that this streamlined reporting form option for any
                manufacturer of R&D substances in low volumes (i.e., below 10 kilograms
                per year) would still provide necessary information to EPA under TSCA
                section 8(a)(7), while minimizing the cost of compliance for certain
                small manufacturers, consistent with TSCA section 8(a)(5), for the data
                elements that EPA understands may not be known to or reasonably
                ascertainable by such manufacturers. However, to the extent any
                additional information requested on the longer forms is known to or
                reasonably ascertainable by the manufacturer (e.g., information on
                disposal of that PFAS, or existing information regarding environmental
                or health effects), the manufacturer would be required to submit that
                information to EPA through the ``optional'' field on the streamlined
                reporting form.
                E. What must be submitted as ``all existing information concerning the
                environmental and health effects'' of a chemical substance?
                 Pursuant to TSCA section 8(a)(2)(E), EPA is requiring the
                submission of ``all existing information concerning the environmental
                and health effects'' of the chemical substances covered by this rule.
                ``All existing information concerning environmental and health
                effects'' is defined as ``any information of any effect of a chemical
                substance or mixture on health or the environment or both'' (to be
                codified at 40 CFR 705.3) and is intended to be interpreted broadly.
                The scope of ``all existing information concerning environmental and
                health effects'' includes all health and safety studies but is not
                limited to formal studies. Chemical identity is always part of a health
                and safety study, and TSCA section 14(b) limits the extent to which
                health and safety studies and information from studies may be withheld
                from the public as confidential business information (CBI). Any
                information that bears on the effects of a PFAS on human health or the
                environment would be included, including information on the chemical
                substance developed or generated prior to the year 2011. The codified
                definition of ``all existing information concerning environmental and
                health effects'' at 40 CFR 705.3 provides non-exhaustive examples, such
                as:
                 Toxicity information (e.g., long- and short-term tests of
                mutagenicity, carcinogenicity, teratogenicity; pharmacological effects;
                acute, subchronic, and chronic effects);
                 Ecological or other environmental effects on fish,
                invertebrates, or other animals and plants, such as bioconcentration or
                bioaccumulation tests;
                 Human and environmental exposure assessments, including
                workplace exposure, and the impacts of a chemical substance or mixture
                on the environment; and
                 Other data relevant to environmental and health effects
                including monitoring data to measure the exposure of humans or the
                [[Page 70524]]
                environment or a chemical substance, range-finding studies, preliminary
                studies, adverse effects reports, and any information, including
                medical screening or surveillance, such as under the American
                Conference of Government Industrial Hygienists (ACGIH).
                 Following public comments, EPA is also clarifying that the scope of
                ``all existing information concerning environmental and health
                effects'' is information in the submitter's possession or control. For
                the purpose of requiring existing information related to health or
                environmental effects, EPA is adopting the same definition of
                ``possession or control'' as in the TSCA Pre-Manufacture Notice (PMN)
                regulations (40 CFR 720.3(y)). Thus, a PFAS manufacturer would not
                necessarily be searching all information in the public realm but would
                be submitting information in their possession or control, or other
                information for which they are responsible. This includes any data or
                other information in files maintained by the submitter's employees, or
                the employees of a submitter's subsidiary or partnership which is
                associated with research and development, test marketing or commercial
                marketing of the PFAS, regardless of the publication status. EPA is not
                requiring manufacturers to search open scientific literature to find
                relevant information on a PFAS that was previously not in their
                possession or control for the purpose of this rule. EPA believes that
                implementing such a requirement may result in duplicative information,
                if multiple PFAS manufacturers are submitting the same studies or other
                information that are available publicly (including in EPA's scientific
                literature databases).
                 EPA considered ways to avoid requiring the submission of
                potentially duplicative information concerning health and environmental
                effects (see TSCA section 8(a)(5)(A)), while still fulfilling EPA's
                obligation under TSCA section 8(a)(7) to require reporting of such
                information. Such information concerning environmental or health
                effects may have been submitted to EPA previously under either TSCA
                section 8(d) rules (as unpublished health and safety information) or
                TSCA section 8(e) (as a substantial risk notice). If a reporter has
                already submitted information concerning environmental or health
                effects to EPA under specific TSCA submissions, they need not re-submit
                that information if they provide the details of to which program (or
                under which rule) that information was submitted and in which year
                (e.g., TSCA section 8(e), in 2010). In the event of a reporter having
                previously submitted relevant environmental and health effects
                information, the reporter must ensure that the previous submission
                included all existing underlying information, including test data. Note
                that a previous submission of information concerning environmental or
                health effects does not relieve a manufacturer of providing all
                existing information concerning environmental or health effects that
                has not previously been submitted to EPA. See Unit III.F for more
                discussion on how EPA is mitigating potentially duplicative reporting
                for this rule.
                 For environmental and health effects information that was
                previously submitted to EPA as CBI, the reporter would need to resubmit
                if that information predated the 2016 Lautenberg Act amending TSCA and
                its CBI submission requirements and reassert the CBI claim (see
                Sec. Sec. 705.22(f) and 705.30). If a reporter has submitted
                environmental and health effects information as CBI since the 2016
                Lautenberg Amendments to TSCA were implemented, then the manufacturer
                must provide EPA with details regarding when, how, and under which
                title and/or statutory authority the CBI claim was submitted, and the
                TSCA section 14 certification. In order for a reporter to earn an
                exemption from resubmitting that environmental and health effects
                information and re-asserting a CBI claim, the reporter must be able to
                point to a previous claim that adequately covers the current claim. In
                any event of a reporter having previously submitted environmental or
                health effects information as CBI, whether pre- or post-Lautenberg
                Amendments, they must adequately substantiate their CBI claim. EPA
                encourages all reporters who have previously submitted environmental or
                health effects information as CBI to carefully review their previous
                submissions and determine whether the previous claims satisfy current
                CBI substantiation requirements, and to assert a new claim and
                substantiate if appropriate. More discussion on submitting CBI under
                this rule is in Unit III.G.
                 Additionally, EPA is finalizing the requirement to submit all
                existing information concerning health and environmental effects in the
                format of OECD-harmonized templates, where such templates exist for the
                type of data (to be codified at 40 CFR 705.15(f)). OECD templates are
                accessible to the public online at https://oecd.org/ehs/templates/harmonised-templates.htm (Ref. 16). This can be accomplished by using
                the freely available IUCLID6 software by exporting the dossier in the
                OECD Harmonized Template working context. At the time of this rule
                publication, EPA can accept any dossiers generated using any version of
                IUCLID6. Users should refer to EPA web pages (to be identified) for
                updates on which version of IUCLID files will be accepted.
                 A standardized format such as the OECD templates will improve the
                efficiency of review and organization of the submitted data. EPA
                believes that some of the data will already be available as an OECD
                template if the company had already submitted the studies under the
                European Union's Registration, Evaluation, Authorization and
                Restriction of Chemicals (REACH) regulation (Ref. 16). In addition to
                the required template format, those subject to this rulemaking must
                submit any associated full study reports or underlying data as support
                documents. The full study reports and support documents are necessary
                for EPA to understand the full context and evaluate the quality of the
                data, which is necessary for the Agency to review to determine whether
                such data may be used for any future Agency actions.
                 If an OECD-harmonized template is not available for a particular
                endpoint for which the manufacturer has relevant information, then the
                manufacturer must still submit the data. Such information may include,
                but is not limited to, raw monitoring data (regardless of having been
                aggregated or analyzed) of human or environmental exposure assessments
                and toxicity tests for either human health effects or ecological other
                environmental effects.
                F. What steps is the Agency taking to reduce potentially
                ``duplicative'' reporting? Does information need to be reported on the
                basis that it has already been reported to the Agency?
                 TSCA section 8(a)(5)(A) requires EPA, to the extent feasible when
                carrying out TSCA section 8, to avoid requiring unnecessary or
                duplicative reporting. The Agency seeks to avoid collecting data on
                PFAS that would duplicate information already reported to the Agency,
                while ensuring EPA obtains all data required to be collected under TSCA
                section 8(a)(7) and that such data are submitted in a format that is
                conducive to the collection and review of a manufactured PFAS dataset.
                While developing this rule, EPA reviewed the data elements submitted
                under the CDR Rule to evaluate whether there may be some overlap with
                the information requested under this rule. Through internal review, and
                from input received
                [[Page 70525]]
                during the public comment periods and the SBAR Panel, the Agency has
                identified the following data elements that may have some overlap with
                CDR requirements:
                 Physical state of the chemical or mixture;
                 Production volume (domestically manufactured);
                 Production volume (imported);
                 Volume directly exported;
                 Indicator for imported but never physically at site;
                 Industrial processing and use type, sector(s), functional
                category(ies), and percent of production volume for each use;
                 Consumer and/or commercial indicator, product
                category(ies), functional category(ies), percent of production volume
                for each use, indicator for use in products intended for children, and
                maximum concentration in the product; and
                 Number of workers reasonably likely to be exposed for each
                combination of industrial processing or use operation, sector, and
                function, and the number of commercial workers reasonably likely to be
                exposed if the PFAS is contained in a commercial product.
                 However, EPA notes that even though there are some potentially
                overlapping data elements between this rule and CDR, any duplication of
                reporting requirements is likely to be narrower in scope. For instance,
                CDR is limited to chemical substances on the Inventory. In contrast,
                the reporting requirements in this rule extend beyond chemicals on the
                Inventory and may cover chemicals subject to LVEs, byproducts, and
                other chemicals that may not have been reported on or added to the
                Inventory. In addition, CDR has a reporting threshold of 25,000 pounds
                (or 2,500 pounds for chemicals subject to certain TSCA actions), along
                with several reporting exemptions, including for imported articles,
                certain byproducts, non-isolated intermediates, and small quantities of
                R&D substances, while this reporting rule does not incorporate any such
                thresholds or exemptions. Finally, while this rule requests the same
                data to be submitted for each year in which a PFAS has been
                manufactured since 2011, CDR requires different information to be
                submitted in different years: for instance, reporters submit the total
                annual domestically manufactured production volume and the total annual
                imported volume separately only for the principal reporting year (e.g.,
                2019 for the 2020 reporting cycle), but only the combined total annual
                production volume is required reporting for the intervening years.
                Additionally, the CDR rule has been amended over the course of this
                reporting period, meaning certain data elements were not requested or
                submitted for all CDR cycles overlapping this rule's lookback period.
                Specifically, the CDR industrial processing and use codes and consumer/
                commercial processing and use codes did not align with the OECD-
                harmonized use codes until the 2020 reporting cycle. While CDR
                submitters may have provided certain processing and use information
                related to PFAS they manufactured during previous CDR cycles, any CDR
                responses that do not sufficiently respond to this data call by
                providing the required OECD codes would not be duplicative of the
                information being reported under this rule. Therefore, while some data
                elements of this rule may be considered duplicative of CDR
                requirements, differences between CDR and this rule's requirements
                (including reporting thresholds and reporting exemptions) may limit the
                scope of what is duplicative and duplicative information does not need
                to be re-reported for this rule. If the previous submission for the
                same data element under a different reporting rule was not accurate for
                purposes of this rule (e.g., by not reporting volumes related to an
                activity exemption that does not apply to this rule, or by reporting
                industrial processing and use information that does not align with the
                OECD-harmonized use codes required under this rule), then the submitter
                must report the accurate information and cannot rely on their prior
                submission to satisfy this rule's requirements.
                 Beyond the CDR rule, some commenters and participants in the SBAR
                Panel suggested that other information requested under this rule may
                have been reported to EPA through a TSCA section 8(d) rule. Under TSCA
                section 8(d), EPA has the authority to request unpublished health and
                safety data studies, or lists of such studies, known to or reasonably
                ascertainable by manufacturers, processors, and distributors of certain
                chemical substances or mixtures. Commenters suggested that some
                ``existing environmental and health effects information'' on PFAS may
                have already been submitted to EPA through a TSCA section 8(d) rule and
                would be duplicative of information requested under this rule.
                 While EPA agrees that any previous submissions of unpublished
                studies under TSCA section 8(d) need not be resubmitted under this TSCA
                section 8(a)(7) rule, EPA does not anticipate that there will be much
                overlap between information requested under this rule and information
                that may have already been submitted through the reporting requirements
                related to the TSCA section 8(d) rule codified in 40 CFR part 716.
                First, only a few substances already listed in a section 8(d) rule
                would meet this rule's definition of PFAS; out of the many examples of
                PFAS, only oxirane, 2-(2,2,3,3,4,4,5,5,6,6,7,7,7-tridecafluoroheptyl)-
                (CASRN 38565-52-5), hexane, 1,1,1,2,2,3,3,4,4,5,5,6,6,6-
                tetradecafluoro- (CASRN 355-42-0), and 1-butanamine, 1,1,2,2,3,3,4,4,4-
                nonafluoro-N,N-bis(1,1,2,2,3,3,4,4,4-nonafluorobutyl)- (CASRN 311-89-7)
                are listed as PFAS, which can be found in 40 CFR 716. Secondly, the
                substances which are listed in 40 CFR part 716 have sunset dates, or
                reporting deadlines. The PFAS that have previously been listed in a
                section 8(d) rule have sunset dates between 1988 and 1995; therefore,
                potentially duplicative section 8(d) reporting stops decades short of
                the scope of reporting for this rule (40 CFR 716) (53 FR 38645,
                September 30, 1988 (FRL-3439-9)). Finally, the scope of ``unpublished
                health and safety studies'' requested under a TSCA section 8(d) rule
                may not be as inclusive as the scope of ``all existing information
                concerning the environmental and health effects'' requested for the
                substances under this TSCA section 8(a)(7) rule. This rule's scope of
                all existing information concerning environmental and health effects is
                intended to be broadly interpreted and is inclusive of any health and
                safety study, regardless of the date the information was collected or
                generated; see the discussion in Unit III.E.
                 Similarly, ``all existing information concerning the environmental
                and health effects'' of a PFAS may include previous submissions to EPA
                pursuant to TSCA section 8(e). TSCA section 8(e) requires
                manufacturers, processors, and distributors of chemicals to notify EPA
                immediately of information that reasonably supports the conclusion that
                their substances or mixtures present a substantial risk of injury to
                health or the environment. To the extent that a substantial risk
                notification under TSCA section 8(e) may be duplicative with this
                rule's requirements, the reporter need not resubmit such information,
                but will be required to indicate when they had previously provided that
                notification under TSCA section 8(e) so that EPA is able to locate that
                previous submission and satisfy the requirements of TSCA section
                8(a)(7). Manufacturers who have previously submitted information to EPA
                under TSCA section 8(d) or TSCA section 8(e) that may be
                [[Page 70526]]
                considered ``existing information concerning the environmental and
                health effects'' of a PFAS for which they are reporting under this TSCA
                section 8(a)(7) rule need not resubmit the duplicative information.
                However, the manufacturer must indicate in the reporting form the year
                in which they had previously provided that information and under which
                rule (e.g., TSCA section 8(d), section 8(e)). If EPA has previously
                collected information relevant to the implementation of TSCA section
                8(a)(7) and is able to locate that information based on the reporter's
                submission, then EPA would be able to meet the information collection
                obligations under TSCA section 8(a)(7) without requiring potentially
                duplicative reporting.
                 EPA also considered other, non-TSCA reporting rules' potential
                overlap with this rule. These include the Toxics Release Inventory
                (TRI) and the Greenhouse Gas Reporting Program (GHGRP). Under the TRI,
                certain industrial and Federal facilities are required to report their
                annual releases and other waste management quantities and activities
                for TRI-listed toxic chemicals that are manufactured, processed, or
                otherwise used above the respective threshold. Information reported to
                TRI that is also requested under this rule includes:
                 Total volume recycled on-site;
                 Description of disposal process(es);
                 Total volume released to land;
                 Total volume released to water;
                 Total volume released to air; and
                 Total volume incinerated on-site.
                 However, in the same vein as the limitations on potentially
                duplicative reporting with CDR and TSCA section 8(d) rules, EPA does
                not anticipate much, if any, overlap in reporting between this rule and
                TRI. First, PFAS were not on the TRI chemical list until the FY 2020
                NDAA automatically added 172 PFAS effective calendar year 2020, with
                additional PFAS added annually since 2020 (Ref. 17). Therefore, the
                only potentially overlapping reporting of PFAS releases and other waste
                management quantities would be since 2020, instead of the entire
                lookback period of this rule. Additional limitations in the potential
                overlap between this rule and TRI include the PFAS reporting threshold
                for TRI of 100 pounds manufactured, processed, or otherwise used and
                certain TRI reporting exemptions for quantities below de minimis
                concentrations and in articles. Without a reporting threshold or
                similar reporting exemptions applicable for this rule, there may be
                more PFAS releases and other waste management activities reportable for
                this rule than for TRI.
                 EPA also considered potential overlaps with GHGRP. The GHGRP
                requires annual reporting of greenhouse gas (GHG) data and other
                information from large GHG emissions sources (i.e., those that emit at
                least 25,000 tons of CO2-equivalent, any electricity
                generation site, aluminum, ammonia or cement production facility, and
                some municipal solid waste landfills), fuel and industrial gas
                suppliers, and carbon dioxide injection sites (Ref. 18) (40 CFR part
                98). 111 compounds covered as GHGs and heat transfer fluids (HTF) would
                also be considered PFAS under this rule. Between this rule and the
                GHGRP, the following data elements may be duplicative for at least some
                GHGRP reporters:
                 Production volume (imported);
                 Volume directly exported; and
                 Total volume incinerated on-site.
                 Besides the limited number of PFAS covered by GHGRP, other
                limitations on the potential overlap between this rule and GHGRP
                include the exemption of GHGRP reporting for quantities imported or
                exported below 25 kilograms. Additionally, not all coincidentally
                manufactured chemicals (such as byproducts) are covered by GHGRP,
                though they fall under the definition of ``manufacture for a commercial
                purpose'' under this rule (40 CFR 705.3). Overall, there is a
                significant difference between the reporting requirements in the GHGRP
                and this rule, though EPA is allowing reporters to abstain from re-
                reporting any of the information listed previously in this unit for a
                PFAS that was previously reported to GHGRP, unless the GHGRP submission
                did not account for all quantities that are covered by this rule.
                 EPA also notes the potential for duplicative reporting of
                environmental releases of certain byproducts within this rule. Pursuant
                to TSCA section 8(a)(2)(D), EPA is requiring PFAS manufacturers to
                provide a ``description of the byproducts resulting from the
                manufacture, processing, use, or disposal of each [PFAS].'' However,
                EPA notes there may be occasions where a byproduct that resulted from
                the manufacture, processing, use, or disposal of a reported PFAS also
                meets this rule's definition of PFAS. Because ``manufacture for
                commercial purposes'' includes the coincidental manufacture of
                byproducts, that byproduct would also need to be reported under this
                rule to the extent data are known or reasonably ascertainable. As a
                reportable PFAS, information on that byproduct's environmental releases
                would be requested twice, both as a byproduct of the originally
                manufactured PFAS and as a commercially manufactured PFAS itself. To
                mitigate potentially duplicative reporting concerns in such situations,
                manufacturers of byproducts that are also reportable PFAS under this
                rule need not re-report the environmental release information of that
                byproduct on the original PFAS's form.
                 To address potentially duplicative reporting, EPA is identifying
                specific types of information that need not be reported if the
                reporting entity indicates in the reporting tool that they have
                previously provided such information to EPA and provides information
                sufficient to allow the agency to locate that information. Pursuant to
                TSCA section 8(a)(5)(A), EPA is limiting the requirement for reporting
                ``duplicative'' information if a PFAS manufacturer has previously
                submitted the requested information to EPA for that same PFAS in that
                same year through CDR, TRI, GHGRP, or TSCA sections 8(d) and 8(e), or
                is also reporting a PFAS byproduct on its own reporting form. Only the
                aforementioned data elements from CDR, TRI, and GHGRP; studies
                submitted under TSCA section 8(d) or 8(e); and certain byproduct
                release information may be exempt from re-reporting under this rule as
                potentially duplicative information. In these cases, the manufacturer
                would be required to indicate to which program (and in which year) that
                information was submitted (e.g., CDR, in 2016). Additionally, EPA notes
                that a manufacturer's previous submission for the same data element
                under a different reporting rule (e.g., a manufacturer previously
                reported the production volume to CDR for a particular year) does not
                necessarily mean that the same quantity or information would be
                accurate for this rule's purposes. Because this rule does not provide
                for the same exemptions as the rules discussed in Unit III.F., the
                manufacturer must ensure that all quantities and other requested
                information for that PFAS are reported under this rule to the extent
                such information is known or reasonably ascertainable. In the previous
                example of a CDR reporter who had previously reported a PFAS's
                production volume, the reporter must ensure that all manufactured
                quantities covered under this rule (including those that are exempt
                from CDR, such as impurities or imported articles) are accounted for.
                If a previous submission for a data element does not account for all
                covered volumes or activities, then the submitter
                [[Page 70527]]
                may not rely on that prior submission to satisfy the reporting
                requirements of this rule.
                 EPA considered other previous information collection requests
                related to PFAS but did not determine those to be ``duplicative'' such
                that reporting may be exempt under TSCA section 8(a)(5)(A). For
                instance, EPA received many public comments asserting that information
                submitted through a PMN is duplicative of the information that would be
                collected through this rule. EPA disagrees. Information collected
                through a PMN (or an LVE) reflects information before manufacture of a
                substance commences.
                 EPA notes that the Agency has also required the submission of
                information on PFAS using a variety of enforcement authorities under
                different environmental statutes. However, most, if not all, of the
                information collected in the course of investigating potential non-
                compliance with, or liability under, TSCA or other statutes is
                different in numerous respects from information requested pursuant to
                this rule. EPA does not anticipate there to be duplicative reporting as
                the enforcement requests are generally narrower in scope. The
                enforcement requests generally focus on fewer years than this rule's
                reporting period, and those requests tend to focus on far fewer
                substances. Additionally, the requested data for enforcement
                authorities is both aggregated and reported in formats differently than
                this rule's requirements. While this rule requires data to be reported
                for each year over the reporting period in which the PFAS was
                manufactured, some enforcement requests have focused on just single
                years, or have requested quantities to be reported to reflect
                cumulative totals over multiple years. In that latter example, such a
                submission would not satisfy EPA's obligations under TSCA section
                8(a)(7) requesting certain information ``for each year since January 1,
                2011.'' In terms of information reporting formats, EPA notes that
                enforcement requests may often ask for responses in a narrative format,
                distinct from this rule's requests for information in quantities or
                within specific ranges. For these discrepancies, EPA does not believe
                that most information requested through previous enforcement request
                letters is duplicative of information requested under this rule.
                 The only information that may have been submitted in response to
                past enforcement letters that may be potentially duplicative of this
                rule relates to ``all existing information concerning environmental and
                health effects.'' Such information includes but is not limited to
                environmental monitoring, sampling, or worker exposure data. Thus, if a
                manufacturer has previously submitted certain information concerning
                environmental or health effects of a PFAS to EPA under an enforcement
                authority, that manufacturer does not need to resubmit that
                environmental or health effects information to EPA under this rule,
                provided that the manufacturer indicates to which program or office and
                in which year such information was submitted to EPA.
                 While the use of those enforcement authorities may be duplicative
                in some cases, the information is needed to ensure protection of public
                health and the environment in instances where the Agency feels it needs
                information from an entity to make that judgment call and determine if
                action is needed. Therefore, information duplication between previous
                enforcement requests and this rule is unlikely for many reasons,
                including various limitations on information gathered under the
                enforcement authorities and the fundamental differences in the type of
                information sought under this rule as compared with the information
                gathered under the other authorities. While information from PFAS
                manufacturers requested by EPA is, in all cases, needed to ensure the
                protection of public health and the environment, the information
                requested under the different authorities serves different purposes.
                EPA has determined that the information submitted in response to an
                enforcement letter is not duplicative of the information requested
                under this rule, except for certain information concerning
                environmental and health effects.
                 Finally, some reporters may also have submitted certain information
                concerning environmental or health effects of a PFAS pursuant to either
                a TSCA section 4 action or voluntarily, in conjunction with EPA's
                National PFAS Testing Strategy. To the extent a reporting entity has
                already provided information concerning environmental or health effects
                (such as chemical and physical properties, hazard testing, or exposure
                testing), that entity need not resubmit the information to this
                reporting rule. Instead, the reporter should indicate that they have
                already submitted such information to EPA and provide the program, the
                specific chemical identity, the date, and an associated case number, if
                available, of that submission.
                G. What are the requirements for submitting CBI claims?
                 The 2016 amendments to TSCA included new procedural requirements
                for the submission and Agency management of CBI claims, including new
                substantiation requirements, generic name requirements, a certification
                requirement, and a requirement for Agency review of specified CBI
                claims within 90 days after receipt of the claim (15 U.S.C. 2613). In
                accordance with the 2016 TSCA amendments, the Agency recently proposed
                a rule addressing the procedures for submitting CBI claims to EPA under
                TSCA and the procedures for EPA's review of such claims (87 FR 29078,
                May 6, 2022 (FRL-8223-01-OCSPP)). PFAS manufacturers reporting under
                this rule may claim certain portions of the reporting form are CBI
                confidential business information, consistent with TSCA section 14,
                such as specific chemical identities that are not on the public
                Inventory, company identifier, and production volumes. Only
                confidentiality claims made through this rule's PFAS reporting tool
                will be considered properly asserted; any additional TSCA CBI claims
                made elsewhere will be considered improperly presented and will not be
                treated as having asserted a CBI claim under TSCA, and the information
                may be disclosed to the public without further notice. In addition to
                the requirement that CBI claims be submitted through the PFAS reporting
                tool, TSCA requires the reporter to certify that it has: (1) Taken
                reasonable measures to protect the confidentiality of the information;
                (2) Determined the information is not required to be disclosed or made
                public under Federal law; (3) A reasonable basis to believe that
                disclosure of the information is likely to cause substantial
                competitive harm; and (4) A reasonable basis to believe that the
                information is not readily discoverable through reverse engineering;
                and, (5) To certify that these statements and any information provided
                are true and correct. Consistent with the format of other TSCA
                reporting forms, the statements and certification would be combined
                into a single certification statement.
                 Information under this rule that may not be asserted as CBI
                includes:
                 Specific chemical identity if the chemical is on the
                public (non-confidential) Inventory or reported as non-confidential in
                an LVE;
                 All generic chemical names;
                 For any PFAS that are on the public (non-confidential)
                Inventory, the chemical's CASRN;
                [[Page 70528]]
                 For PFAS that are on the confidential Inventory, the
                Inventory Accession Number cannot be claimed as CBI (but the underlying
                chemical identity can be claimed as CBI);
                 LVE numbers;
                 The following categories of use information: industrial
                processing and use type, sector, and functional categories, whether a
                chemical is in a consumer and/or commercial product, the consumer/
                commercial product categories and functional categories, and its
                presence in products for children; or
                 Any blank or NKRA designation or response.
                 Any entity that claims a specific chemical identity as CBI must
                also submit a generic name pursuant to TSCA section 14(c)(1)(C). This
                includes reporting a PFAS by either an Accession number or LVE number
                (assuming that the specific chemical identity is not on the public
                Inventory), or reporting by a CAS name on a PFAS for which the CASRN,
                Accession number, and LVE number are not known to be assigned (i.e.,
                the CASRN and specific identifiers have not been created or generated).
                Entities must ensure that that any such generic name is consistent with
                EPA's Generic Name Guidance (Ref. 19). The generic name must also
                ``describe the chemical structure of the chemical substance as
                specifically as practicable while protecting those features of the
                chemical structure that are claimed as confidential; and the disclosure
                of which would be likely to cause substantial harm to the competitive
                position of the person.'' 15 U.S.C. 2613(c)(1)(C)(ii). Generic names
                must be sufficiently detailed to identify the reported chemical as a
                PFAS. Specifically, any generic name reported for a PFAS that does not
                contain ``fluor'' in the name would be rejected by EPA as insufficient
                under TSCA section 14(c)(1)(C). As the Agency described in the NODA
                published for this rule (Ref. 1), any generic name for a PFAS
                (including previously existing generic names from earlier TSCA section
                5 submissions) that does not contain ``fluor'' in the name is
                inconsistent with this provision and will be rejected. Ultimately, if a
                generic name reported under the TSCA section 8(a)(7) rule lacks the
                structural unit ``fluor,'' the Agency will publicly identify the
                chemical substance as a PFAS.
                 TSCA section 14 further requires that substantiation be provided
                for each data element claimed as CBI. The substantiation must be
                provided at the time of submission. However, TSCA section 14(c)(2)
                exempts certain information from the substantiation requirements (e.g.,
                specific production volume). Under this rule, CBI claims for specific
                production or import volumes of the manufacturer need not be
                substantiated. Additionally, the specific chemical identity and
                molecular structure need not be substantiated when the substance has
                not been introduced into commerce (e.g., an R&D substance manufactured
                in small quantities meeting the new chemical reporting exemption under
                section 5(h)(3)). No other TSCA section 14(c)(2) exemptions apply to
                information requested under this rule, so CBI claims must be
                substantiated for all other such information. Any information which is
                claimed as CBI will be disclosed by EPA only in accordance with the
                procedures and requirements of TSCA section 14 and 40 CFR parts 2 and
                703. TSCA limits CBI protections for information in health and safety
                studies.
                 Generally, information from health and safety studies is not
                protected from disclosure, except to the extent such studies or
                information reveal information ``that discloses processes used in the
                manufacturing or processing of a chemical substance or mixture or, in
                the case of a mixture, the portion of the mixture comprised by any of
                the chemical substances in the mixture,'' 15 U.S.C. 2613(2)(B).
                Additional information, listed in the rule's definition of health and
                safety study, are not part of a health and safety study (e.g., names of
                laboratory personnel). Submitters asserting a CBI claim for information
                under Sec. 705.15(f) are required to submit a sanitized copy, removing
                only the information that is claimed as CBI.
                 EPA expects that article importers generally do not know the
                Accession number or other specific identifiers (e.g., PMN or LVE
                number) for a confidential Inventory chemical that may be included in
                the article they are importing. As a result, article importers must
                report chemical identities to the extent that they are known to or
                reasonably ascertainable (generic name, trade name, or CASRN if it is a
                publicly known chemical substance) and use the article importer
                streamlined form. Public identifiers like generic names and public
                Inventory CASRNs may not be claimed as CBI and it is unnecessary for
                article importers to assert CBI claims for the specific identities of
                substances that are not reported by a specific identifier (i.e.,
                Accession number or LVE number). EPA would not be able to determine an
                underlying confidential chemical identity from this generic identifying
                information, so could not disclose that specific chemical identity,
                regardless of whether the submitter asserted a CBI claim. It would be
                purposeless for the submitter to assert a CBI claim for this
                information or for EPA to review such claims. In this TSCA section
                8(a)(7) rule, and for these reasons, EPA believes that it is
                appropriate to differentiate article importers from other reporters
                with respect to chemical identity CBI claims.
                 However, all other entities (i.e., other than article importers)
                who report a CAS name, CASRN, or specific identifier (i.e., Accession
                number, LVE number) must assert and substantiate a CBI claim for the
                specific chemical identity if the reporter wants the chemical identity
                to receive confidential treatment. A person or entity (other than an
                article importer) who does not have knowledge of such an identifier
                (CAS name, CASRN, Accession number, or LVE number) must initiate a
                joint submission with its supplier or other entity who can provide this
                identifying information, if such an entity is known to or reasonably
                ascertainable by the manufacturer. In these cases, the secondary
                submitter would be responsible for providing the CAS name, CASRN,
                Accession number, or LVE number and for asserting and substantiating
                any CBI claims concerning the chemical identity (see e.g., 40 CFR
                711.15(b)(3); 711.30(c)). In light of the extended timeframe (11 years)
                covered by this reporting rule, it is possible that the submitter's
                supplier is unknown or no longer exists (e.g., supplier has gone out of
                business without a successor entity). As applied to this reporting rule
                only, a submitter who lacks knowledge of the CAS name, CASRN or a
                specific identifier (i.e., Accession number or LVE number) and who--
                after conducting due diligence and reviewing known or reasonably
                ascertainable existing information--cannot identify a supplier or any
                other entity who could provide this information in a joint submission,
                the submitter would indicate that secondary submitter information is
                not known or reasonably ascertainable and therefore does not need to
                initiate a joint submission.
                 Generally, reporting entities will not have an opportunity to add
                or modify substantiations once the reporting period concludes.
                Therefore, reporting entities should communicate with suppliers, or any
                other entities with CBI concerns (e.g., non-disclosure agreements) and
                carefully consider the CBI implications of this rule. However,
                reporting entities may amend their submission to withdraw CBI claims at
                any time during the reporting period.
                 In response to comments received on CBI claims concerning the
                specific chemical identity, following the
                [[Page 70529]]
                conclusion of the reporting period for this rule, EPA will compile a
                list of reported substances it plans to move to the public Inventory
                because either no chemical identity CBI claim was asserted, or the
                claim was denied. Similar to past compilations, EPA will publish a list
                of Accession numbers associated with these substances on the EPA
                website for several months in advance of any update to the Inventory.
                Interested parties will have an opportunity to review the list for
                possible errors and contact EPA with any questions or concerns about
                specific candidates. In some cases, there may be assertions by a
                company that a mistake has been made (e.g., the wrong chemical identity
                was reported by a third party) or that a waiver of a CBI claim was made
                by a company that may not know the specific chemical identity, in which
                case EPA will undertake appropriate factual investigations as necessary
                to confirm whether EPA should reconsider whether the chemical is no
                longer entitled to confidential Inventory protection. Where EPA
                determines that a chemical identity was identified as a candidate for
                disclosure because there was an error or because the sole basis for the
                proposed move to the public portion of the Inventory was a waiver of a
                CBI claim by an entity that did not know the specific chemical
                identity, it will not move the chemical identity to the public portion
                of the Inventory. This investigation would take place prior to the
                point that the specific chemical identity would be disclosed on the
                public Inventory.
                H. What are the electronic reporting requirements?
                 EPA is requiring all information to be submitted electronically,
                similar to the requirements established in 2013 for submitting other
                information under TSCA (see 40 CFR 704.20(e)). Reporters must use EPA's
                Central Data Exchange (CDX), the Agency's electronic reporting portal,
                to submit all information under this rule. EPA developed the Chemical
                Information Submission System (CISS) for use in submitting data
                electronically to the Agency for TSCA sections 4, 5, 6, 8(a), 8(b),
                8(d), and 8(e) and Title VI. CISS, a web-based reporting tool housed
                within the CDX environment, provides submitters with user-friendly
                applications to build and submit data packages to EPA within a secure,
                encrypted environment. CISS applications provide for the capture of
                both fielded data as well as the attachment of additional information
                using a wide variety of file types. Within CDX, CISS is available under
                the ``Submission for Chemical Safety and Pesticide Program (CSPP)'' CDX
                flow. Users who have previously submitted under TSCA through CDX,
                including submitting information under sections 4 and 5, or CDR, will
                already have the CSPP flow linked to their account. Users reporting to
                EPA using other CDX housed applications, including the Toxics Release
                Inventory TRI-MEweb, would be able to add the CSPP flow to their
                existing CDX accounts.
                 EPA is developing a rule-specific reporting tool within CISS, which
                reporters must use to submit the required information. This tool will
                be available in CISS prior to the start of the reporting period (see
                the discussion in Unit III.I on reporting deadlines). EPA believes that
                electronic reporting reduces the reporting burden for submitters by
                reducing the cost and time required to review, edit, and transmit data
                to the Agency. It also allows submitters to share a draft submission
                within their organization and more easily save a copy for their records
                or future use. Additionally, EPA believes that many of the anticipated
                reporters under this rule have experience with reporting electronically
                to EPA through CDX. For those reporters who do not have experience
                submitting information to EPA via CDX, EPA has provided guidance
                documents and support via a help desk to assist users with technical
                questions related to CDX. The resource and time requirements to review
                and process data by the Agency will also be reduced, and document
                storage and retrieval will require fewer resources.
                I. What if an entity who knows the specific chemical identity will not
                disclose it to the PFAS manufacturer (including importer)?
                 In response to public comment, EPA is also enabling joint
                submissions for PFAS manufacturers (including importers) other than
                article importers who do not know the CASRN, Accession Number, and/or
                LVE number and whose suppliers will not disclose the identity to the
                PFAS reporter. Similar to the 2020 CDR cycle, this joint submission
                tool would allow manufacturers (including importers) to submit all
                importing, processing, use, and other information to the extent it is
                known or reasonably ascertainable and to send a request to the
                appropriate supplier or other entity to create a submission to supply
                the PFAS identity to EPA through the reporting tool. The joint
                submission process does not require the supplier or other entity to
                disclose the specific chemical identity to their customer, thus
                maintaining confidentiality between the two entities.
                 The joint submission tool would be relevant when a manufacturer
                (including importer) cannot provide the CAS name, CASRN, Accession
                number, or LVE number of a chemical substance it manufactures,
                generally because it is unknown to the manufacturer (including
                importer) and claimed in part or in its entirety as CBI by the supplier
                of the chemical substance or mixture.
                 In a joint submission, the primary submitter (i.e., the PFAS
                manufacturer) may assert CBI claims over some of their supplier
                information, including the supplier identity and the chemical substance
                or mixture trade name (or other designation). Substantiation of the CBI
                claims for this information will not be required at the time of the
                primary submitter's submission. The secondary submitter of the joint
                submission must register with CDX if they have not previously and
                provide its company name and location, a technical contact, trade name,
                chemical identity, function, and, for PFAS in mixtures, the percentage
                of each PFAS in the mixture represented by the trade name. The
                secondary submitter is responsible for asserting all confidentiality
                claims for the data elements that it submits directly to EPA and for
                substantiating those claims not exempt under 40 CFR 705.30(a)(2). The
                specific chemical identity may be claimed as CBI by the secondary
                submitter following the provisions in 40 CFR 705.30. If the secondary
                submitter does not assert and substantiate a CBI claim for the identity
                of the chemical substance in its response to the Agency, then the
                chemical is not entitled to confidential treatment. Except for the
                percentage composition information, which is generally exempt from
                substantiation pursuant to TSCA section 14(c)(2)(D), all other reported
                data elements are subject to substantiation at the time the information
                is submitted.
                 Similar to the CDR joint submissions, any secondary submitter in
                this rule will be able to request the chemical information from their
                own suppliers as needed, should the importer's direct supplier not have
                the information. There may be instances where a foreign supplier
                purchases a mixture, under a trade name, from another company (tertiary
                company) and does not know the chemical components of the mixture. The
                foreign supplier can ask the tertiary company manufacturing the trade
                secret mixture or PFAS within the mixture to directly provide EPA with
                the correct chemical identity in the reporting tool. In this case, the
                tertiary company would register with CDX and use the Unique Identifier
                for Joint Submissions, sent to the tertiary
                [[Page 70530]]
                company by the secondary company (i.e., the foreign supplier), to
                complete the reporting form.
                 Under this scenario, the foreign supplier does not have access to
                any of the information submitted to EPA by the tertiary company.
                Likewise, the tertiary company cannot see the information the foreign
                supplier or the primary company (i.e., the U.S. manufacturer (including
                importer)) reports to EPA. This way, the confidentiality of information
                for all parties is protected. EPA believes this functionality addresses
                some concerns that have been voiced from stakeholders, including an
                importer's direct (or immediate) supplier may not have knowledge of the
                PFAS identity. By allowing a foreign supplier (secondary submitter) to
                request the required information from their own supplier (a tertiary
                submitter) as needed, EPA believes this will capture more information
                related to specific PFAS identities that may not be known to the
                importer due to confidentiality or trade secret claims, while not
                requiring suppliers to share any information they wish to protect from
                their customers.
                 Joint submissions are to be used only in cases when the PFAS
                reporter does not know the CAS name, CASRN, Accession number, or LVE
                number for the PFAS, but another entity (e.g., a supplier or other
                manufacturer) does and will not disclose it to the reporter. If a
                reporter (including importer) or joint reporter (secondary or tertiary
                submitter) actually knows or can reasonably ascertain the CAS name,
                CASRN, Accession number, or LVE number of a PFAS, the reporter
                (including importer) must provide that information irrespective of
                others' confidentiality claims. If the reporter wishes to claim the
                specific chemical identity as confidential, the chemical substance must
                not be listed on the public portion of the Inventory, the submitter
                must check the CBI box in the reporting tool and provide the
                appropriate substantiation. Such a CBI claim only relates to the
                specific chemical identity as listed on the confidential portion of the
                Inventory (i.e., CAS name and/or CASRN) and does not apply to the
                Accession number and generic name listed on the public portion of the
                Inventory.
                 Because article importers are not required to assert or
                substantiate CBI claims for the chemical identity for this rule, EPA is
                not requiring or enabling joint submissions for article importers when
                they do not know the CAS name, CASRN, Accession number, or LVE number
                of the PFAS. Additionally, in scenarios where a secondary submitter is
                not known or existent (e.g., a supplier has gone out of business and
                does not have a successor entity), the primary submitter would indicate
                in the reporting tool that the secondary submitter is ``not known or
                reasonably ascertainable.'' In this case, however, the PFAS
                manufacturer would be required to provide as much identifying detail as
                they have regarding the PFAS identity (e.g., trade name), but would be
                able to report to EPA without initiating a joint submission.
                J. When are reports due?
                 EPA proposed a six-month information collection period following
                the effective date of the final rule, then a six-month reporting
                period. Thus, the proposed rule stipulated a reporting deadline one
                year following the effective date of the final rule. EPA received many
                public comments on the reporting timeframe, which are detailed in Unit
                IV.K.
                 In response to public comment, EPA has decided to finalize a one-
                year information collection period following the effective date of this
                rule, which will then be followed by a six-month reporting period.
                Further, EPA is granting an additional six months for reporting to
                small manufacturers (as defined at 40 CFR 704.3) whose reporting
                obligations under this rule are exclusively from article import.
                ``Small manufacturers'' as defined at 40 CFR 704.3 include
                manufacturers who meet one of two standards: (1) a manufacturer
                (including importer) whose total annual sales, when combined with those
                of its parent company, are less than $120 million, and the annual
                production volume of a chemical substance is less than 100,000 lbs; or
                (2) a manufacturer (including importer) whose total annual sales, when
                combined with those of its parent company, are less than $12 million.
                EPA acknowledges that the scope of reporting for this rule is broader
                than for CDR, and that there may be some reporting entities who have
                not submitted information to EPA under a TSCA section 8(a) reporting
                rule before (e.g., some small manufacturers). Therefore, EPA agrees
                that additional time is warranted for PFAS manufacturers to familiarize
                themselves with the scope of the reporting rule and reporting standard,
                as well as begin to collect the required information and create a CDX
                account if necessary. The extended time period for information
                collection also benefits both EPA and the reporting community by
                providing the Agency with additional time to develop and test the CDX
                reporting application for this rule. Thus, reporting forms will be due
                18 months following the effective date of this rule, except for small
                article importers (as defined at 40 CFR 704.3), whose reporting forms
                are due 24 months following the effective date of this rule.
                K. What are the recordkeeping requirements?
                 EPA is finalizing the proposed recordkeeping requirements. Each
                person who is subject to the reporting requirements must retain records
                that document any information reported to EPA for five years, beginning
                on the last date of the information submission period. The five-year
                retention requirement is consistent with the CDR rule and corresponds
                with the statute of limitations for violations and is necessary to
                preserve records to support future regulatory activities that will be
                informed by this information collection. Further, EPA believes the
                burden of retaining these records, which are likely electronic, is
                minimal.
                L. Which proposed requirements are not being finalized as proposed?
                 EPA is modifying the following items from the proposed rule: the
                definition of ``PFAS''; the reporting deadline; some of the data
                elements requested; enabling streamlined reporting options for article
                importers and manufacturers of R&D substances below 10 kilograms;
                enabling joint submissions; and [certain waste management/disposal
                facility exemptions].
                 As noted in Unit III.A.1, this rule defines ``PFAS'' as including
                at least one of these three structures:
                 R-(CF2)-CF(R')R'', where both the
                CF2 and CF moieties are saturated carbons;
                 R-CF2OCF2-R', where R and R' can
                either be F, O, or saturated carbons; and
                 CF3C(CF3)R'R'', where R' and R'' can
                either be F or saturated carbons.
                 This definition is an expansion of the proposed definition of
                ``PFAS'', which was defined as R-(CF2)-CF(R')R'', where both
                the CF2 and CF moieties are saturated carbons, and none of
                the R groups can be hydrogen. The proposed definition defined PFAS as a
                substance that includes the following structure: R-(CF2)-
                C(F)(R')R'', in which both the CF2 and CF moieties are
                saturated carbons and none of the R groups (R, R' or R'') can be
                hydrogen. The proposed definition, which existed previously in EPA's
                Office of Pollution Prevention and Toxics (OPPT), was developed to
                focus on chemical substances in the Inventory with properties similar
                to PFOA, PFOS, and GenX. EPA notes that the proposed definition of
                ``PFAS'' had previously been used by OPPT, although this definition has
                changed
                [[Page 70531]]
                over time. For instance, the polymer exemption for PMNs provided a
                different definition of ``perfluoroalkyl'' in its PFAS exception rule
                in 2010 (40 CFR 723.250) (Ref. 20). Over many years of research and
                data collection, EPA continues to learn more about these substances and
                may consider whether modifications to the definition are appropriate.
                See Unit IV.A.1 for a more detailed discussion of EPA's reasons for
                modifying this definition for this rule.
                 EPA is also modifying the reporting deadline from the proposed
                rule. As noted in Unit III. J, EPA believes additional time for rule
                familiarization and data collection is warranted given the lookback
                period of this rule and that there are entities that are potentially
                covered by this rule which have not been previously required to respond
                to other TSCA section 8 reporting rules, such as CDR. Given public
                comments and input during the SBAR Panel, EPA is providing a one-year
                period following the effective date of this rule for data collection,
                followed by a six-month reporting period during which the reporting
                application will be open. EPA is further granting an additional six
                months for reporting to small manufacturers (as defined at 40 CFR
                704.3) who would report exclusively as article importers for the
                purpose of this rule. Thus, reporting forms are due 18 months following
                the effective date of this rule, except for small article importers,
                which are due 24 months from the effective date of this rule.
                 EPA is slightly modifying the data elements requested by PFAS
                manufacturers. Based on public comments, EPA is not including the
                following proposed data elements within this rule: the maximum quantity
                on-site at any time, including storage; the maximum first 12 months
                production volume, and the maximum yearly production volume in any 3
                years. EPA received public comment that it is unlikely that
                manufacturers have information related to the storage quantities, and
                other comments stated that requesting the maximum production quantities
                in either the first 12 months or in any three years may be duplicative
                of other production volume data requested. Therefore, EPA is removing
                these three items from the scope of the final rule. For more discussion
                on the comments received on the scope of data elements, see the
                Response to Comments document (Ref. 21).
                 Pursuant to public comments, EPA is also modifying the request for
                the molecular structure of the PFAS in all reports: submitting
                molecular structure of the reported PFAS is optional for any Class 1
                PFAS on the Inventory. Class 1 chemical substances are those chemical
                substances composed of molecules with particular atoms arranged in a
                definite, known structure. If a Class 1 substance is also on the
                Inventory, EPA knows its particular molecular structure. However, many
                commercially-manufactured chemicals are not Class 1 substances (i.e.,
                they are Class 2 substances comprised of specific molecular formula
                representations in variable structures, or they have unknown or
                indefinite molecular formulas and/or incomplete structural diagrams).
                Additionally, not all commercially-manufactured substances that are
                subject to TSCA may be on the Inventory due to various reporting
                exemptions. While EPA has the authority and obligation to request the
                molecular structure of any reported PFAS pursuant to TSCA section
                8(a)(2)(A), EPA does already know the structure of Class 1 substances
                on the Inventory; thus, pursuant to TSCA section 8(a)(5)(A), EPA is
                limiting the scope of this reporting requirement in cases where the
                information would be duplicative of information EPA has obtained
                through TSCA reporting. Therefore, EPA is modifying the proposed rule
                by limiting the reporting requirement of molecular structures to those
                PFAS that are not Class 1 substances on the Inventory.
                 Finally, EPA is also modifying the proposed data elements for
                worker exposure duration. EPA proposed to request information on worker
                exposure for the manufacturing site, each industrial process and use,
                and each commercial use. For all three categories, EPA proposed to
                request ``maximum duration of exposure for any worker'' in both hours
                per day and days per year. However, following the publication of the
                proposed rule, EPA understands that the worker exposure duration
                information, as proposed, could lead to a manufacturer reporting
                unassociated variables; that is, the worker with the maximum duration
                of exposure in hours per day is not the same as the worker with the
                maximum duration of exposure in days per year. Without additional
                clarifying information on which worker(s) the reported durations
                reflect, such a request may not yield data useful for EPA's
                assessments. EPA is therefore modifying the proposed request for the
                worker exposure duration data by clarifying the workers for whom the
                maximum exposure durations or frequency must be reported. EPA is
                requesting worker exposure duration information (in hours per day and
                days per year) both for the worker with the greatest daily exposure
                duration (i.e., the worker with the greatest exposure in hours per day)
                and for the worker with the greatest annual exposure frequency (i.e.,
                the worker exposed during the most days per year).
                 Additionally, EPA is modifying the scope of data elements requested
                for some article importers and manufacturers of R&D substances in
                quantities below 10 kilograms annually. Based on feedback through
                public comments and the SBAR Panel, EPA understands that some article
                importers and some manufacturers of R&D substances may not know or be
                able to ascertain all information being requested. Therefore, EPA is
                offering two streamlined reporting options for those manufacturers.
                (For more information on these reporting options, see additional
                discussions in Units III.D.2 and III.D.3.)
                 EPA is also modifying the proposed rule by enabling joint
                submissions. In the proposed rule, EPA did not propose joint
                submissions, but did specifically request comment on whether to enable
                them for this rule in cases where a supplier may not disclose the
                chemical identity to an importer who is covered by this reporting rule.
                Following public comments, EPA is finalizing this rule to include joint
                submissions for situations in which an importer does not know the CASRN
                or specific identifier (i.e., Accession number or LVE number) (see Unit
                III.I.). EPA further discussed requiring submitters who lack knowledge
                of a chemical's specific chemical identity to initiate a joint
                submission in the NODA.
                 Finally, EPA is modifying the scope of reportable activities under
                this rule to clarify that importing municipal solid waste streams for
                the purpose of disposal or destruction is not a reportable activity
                under this rule. As explained in Unit III.B.3., EPA learned through
                public comments and the SBAR Panel that entities engaged in certain
                municipal solid waste management activities are in the unique position
                of not having any knowledge of the contents of the municipal solid
                waste they have imported. Therefore, extending reporting requirements
                to such sites would not result in any responsive information under TSCA
                section 8(a)(7), and EPA does not consider the import of municipal
                solid waste for the purpose of disposal or destruction to be a
                reportable activity.
                IV. Summary of Comments and Other Public Input and EPA's Response
                 EPA received 109 unique public comments during the proposed rule's
                public comment period. Following
                [[Page 70532]]
                publication of the proposed rule, EPA received more data related to the
                proposed rule's burden and cost estimates. At the time of the proposed
                rule's publication, EPA did not have sufficient and reliable data to
                inform an estimate of the scope of article importers that may be
                affected by the proposed rule's requirements. However, after receiving
                comments through the docket related to the scope of article importers
                (including estimates provided by companies and industry trade
                associations), and through the discovery of additional information and
                data sources related to the scope of potentially affected article
                importers, EPA determined the proposed rule could no longer support a
                certification under the Regulatory Flexibility Act (RFA), 5 U.S.C. 601
                et seq., that there would be no significant economic impact on a
                substantial number of small entities. Specifically, the number of small
                businesses who may be considered importers of PFAS-containing articles
                and therefore potentially affected by the proposed rule was estimated
                to be approximately 130,000. Thus, EPA convened an SBAR Panel under the
                RFA to hear directly from small entities on the anticipated impact of
                the proposed rule on their organizations, and to hear feedback
                regarding recommended paths forward to finalize a rulemaking that would
                minimize the burden of compliance on small entities while still
                achieving the objectives of TSCA section 8(a)(7). This Panel convened
                in April 2022, with a Panel Outreach meeting conducted on April 20,
                2022. The Panel (which included EPA, Office of Management and Budget
                (OMB), and Small Business Administration (SBA) representatives) used
                feedback from the small entity representatives submitted during and
                after the Outreach meeting to develop its Panel Report (Ref. 22), which
                included recommendations for EPA to consider in its final rule.
                 Along with public comments on the overall cost estimates of the
                2021 proposed rule, EPA received many public comments both in support
                of and against EPA's position to not exempt entities or activities that
                are often exempt under CDR, including small manufacturers and article
                importers, and the use of a structural definition for PFAS rather than
                a discrete list of substances.
                 Following this Panel, EPA published a NODA (Ref. 1) to solicit
                public comment on the rule's IRFA and other aspects of the proposed
                rule that may have been impacted by EPA actions or proposed actions
                since the public comment period had closed for the proposed rule in
                September 2021. EPA also published the SBAR Panel Report (Ref. 22) for
                public comment. The notice was published on November 25, 2022 (Ref.1),
                for a 33-day public comment period ending on December 27, 2022. EPA
                received 44 unique public comments during the public comment period
                following the publication of the NODA (Ref. 1). Comments largely
                focused on different regulatory alternatives presented in the Panel
                Report (including certain exemptions, or using a discrete list of
                covered PFAS) and on EPA's discussion of its approach to CBI claims of
                the chemical identity.
                 EPA considered all comments and other stakeholder input, including
                from the SBAR Panel, in the development of this final rule. This unit
                discusses many of the comments on the proposed rule received through
                both avenues and the Agency's responses; however, the more
                comprehensive response to comments related to this rule can be found in
                the Response to Comments document, which is available in the docket for
                this rulemaking (Ref. 21).
                A. What is the proposed definition of covered substances?
                1. Summary of Public Input
                 Many commenters provided feedback on the specific definition of
                PFAS in the proposed rule. These commenters either were unsupportive of
                EPA's definition and requested that the Agency narrow the proposed
                definition of PFAS or requested that EPA broaden their definition of
                PFAS, while generally supporting EPA's proposed structural definition.
                 Commenters who were generally unsupportive of EPA's proposed
                definition of PFAS noted that ``the proposed rule contains a definition
                of `PFAS' not recognized by any other federal agency or international
                organization, and which EPA itself does not use consistently.'' One
                commenter mentioned that treating PFAS as a single group or class of
                chemicals is ``not scientifically sound or appropriate'' due to it
                being ``over- and under-inclusive.'' Another commenter stated that
                EPA's proposed definition of PFAS is overly expansive ``because it
                includes molecules that are not obviously PFAS'' such as ``highly
                fluorinated molecules that are not PFAS by any common understanding of
                PFAS.'' This commenter suggested that the definition of PFAS in the
                final rule ``hew much more closely to the types of PFAS molecules that
                motivated Section 7351 of the NDAA 2020.'' Commenters who suggested
                that EPA's proposed PFAS definition is overly broad, also suggested
                that an overly broad PFAS definition will ``almost certainly'' result
                in unnecessary reporting of ``PFAS molecules' that are ``likely
                unrelated to the underlying problems.''
                 Some commenters suggested that EPA use the OECD definition of PFAS,
                with a few commenters recommending that EPA define PFAS ``at least as
                broadly as the recent OECD definition.'' Supporters of adopting the
                OECD definition claimed that the OECD definition incorporates sound
                science based on input from the ``world's leading developed countries,
                including scientists from EPA'' and mentioned that it might make
                reporting compliance easier for PFAS manufacturers who have a global
                presence. Another commenter who supported use of the OECD definition
                mentioned that EPA's proposed definition excludes ``many PFAS of known
                concern, undercutting the benefits of the Agency's actions.''
                 A few commenters who claimed that EPA's proposed PFAS definition is
                overly narrow, mentioned that other regulatory agencies in some states
                have taken a ``class-based approach'' to PFAS by regulating them as a
                chemical class. Commenters specifically cited Vermont, Massachusetts,
                and California as examples of States that are regulating PFAS in this
                way, ``given that all PFAS, or their degradation, reaction, or
                metabolism products, display commonly hazardous traits.'' Some
                commenters pointed to additional States (Colorado, Maine, Washington)
                that have adopted or are considering adopting a broader definition of
                PFAS similar to the OECD definition.
                2. EPA's Response
                 EPA appreciates that there are differences between the definition
                of PFAS used for this rule, for other actions in the Agency, and by
                non-EPA entities. While EPA's rule is not dictated by the definitions
                used by other regulatory bodies or international organizations, the
                Agency did consider adopting the different definitions suggested by the
                commenters, but ultimately determined those definitions would not
                satisfy EPA's obligations under TSCA section 8(a)(7). In the
                development of this proposed definition, EPA intended to include
                substances with a strong electron withdrawing nature as this greatly
                effects the chemistry of the substituted, adjacent and nearby atoms,
                meaning they would have a minimum of two fluorine atoms on at least one
                carbon (e.g., -CF2-). Additionally, EPA wanted the covered
                substances to be unlikely to degrade or metabolize, so an adjacent CF
                group was added to the requirement/
                [[Page 70533]]
                definition, with the stipulations that the substitutions could not be H
                and both carbons must be saturated (e.g., -CF2-CFR-). EPA
                also thought that branching might make a chemical less susceptible to
                degradation and metabolism, so EPA also removed the option for -
                CF2-CF2- when developing the proposed definition.
                 After reviewing public comments, EPA is modifying the proposed
                definition of PFAS. For the purposes of this section 8(a)(7) reporting
                rule, EPA is defining ``PFAS'' using a structural definition. PFAS is
                defined as including at least one of these three structures:
                 R-(CF2)-CF(R')R'', where both the
                CF2 and CF moieties are saturated carbons;
                 R-CF2OCF2-R', where R and R' can
                either be F, O, or saturated carbons; and
                 CF3C(CF3)R'R'', where R' and R'' can
                either be F or saturated carbons.
                 For the purposes of this rule, EPA has defined PFAS to include
                chemical substances whose structures or sub-structures resemble, at
                least in part, chemicals widely known to be of concern to human health
                and/or the environment, i.e., PFOA, PFOS, and GenX. The definition also
                captures substances that may metabolize or degrade to PFAS which may
                present similar properties to PFOA, PFOS, or GenX. This definition is
                focused on substances likely to be present in the environment, thereby
                focusing on substances with greater potential for exposures to people
                and/or the environment and by extension more potential to present
                risks.
                 EPA considered adopting OECD's definition for the purpose of this
                rule, but for the reasons provided in this unit, determined it is not
                appropriate to do so. First, EPA notes that ``alkyl'' means an alkane
                missing one hydrogen, and acyclic alkyl has the general formula of
                CnH2(n+1), while a cycloalkyl has the general
                formula CnH2(n-1). Rather than limiting the
                definition of PFAS to alkyl chains, the OECD definition covers, with
                certain exceptions, any chemical with one or more fluorinated alkyl
                groups (i.e., -CF2-, -CF3). Many chemical
                substances covered by the OECD definition are unlike the structures of
                the PFAS of concern (i.e., PFOA, PFOS, GenX), which have more
                fluorinated carbons and are more likely to be present in the
                environment. The substances with only single fluorinated alkyl groups
                and no additional fluorinated moieties do not share the same
                environmental and/or human health impacts (including bioaccumulation,
                persistence, or toxicity) as substances such as PFOA, PFOS, or GenX.
                Further, many substances with one terminal -CF3 (e.g.,
                trifluoroacetic acid (TFA)) are well-studied. Using structures in the
                CompTox Chemicals Dashboard, EPA estimates that approximately 23,000
                additional substances would be captured by the OECD definition, though
                approximately 17,000 of those would be covered only due to having one
                terminal -CF3 and no additional fluorine. Thus, adopting the
                OECD definition of PFAS in this rule would mainly serve to
                significantly add reporting burden on many substances whose only
                fluorine atom is in a terminal -CF3 and that do not share a
                fluorinated substructure that is likely to result in their persistence
                in the environment, nor to degrade to a substance that shares
                toxicological or physiochemical properties with PFOA, PFOS, or GenX.
                Therefore, EPA is using its authority under TSCA section 8(a)(5)(A) to
                focus reporting on structures that contain at least one fluorinated
                alkyl chain rather than isolated fluorinated alkyl groups. Information
                on structures that would meet the OECD definition due to an isolated
                fluorinated alkyl group is considered ``unnecessary'' for the purpose
                of this rule and is out of scope of reporting requirements under EPA's
                authority under TSCA section 8(a)(5)(A).
                 Further, OECD's general definition is ``based on molecular
                structure alone'' (Ref. 8). In its 2021 terminology document, OECD
                notes that the current definition ``serves as a starting and reference
                point to guide individual users to have a comprehensive understanding
                of the PFAS universe and to keep the big picture of the PFAS universe
                in mind. At the same time, individual users may define their own
                working scope of PFASs for specific activities according to their
                specific needs by combining the general definition of PFASs with
                additional considerations (e.g., specific properties, use areas)''
                (Ref. 8). Accordingly, EPA determined it is appropriate to define
                ``PFAS'' differently for this rule and to establish a definition which
                characterizes PFAS based on pre-defined traits. Substances which meet
                the OECD's definition of PFAS but that would not be considered PFAS
                under this rule do not share properties with substances of concern to
                EPA (i.e., PFOA, PFOS, and GenX). As noted previously, EPA is defining
                PFAS for this rule to focus on reporting that is necessary under TSCA
                section 8(a)(7), while reducing unnecessary or duplicative reporting
                pursuant to EPA's obligations under TSCA section 8(a)(5)(A).
                 Additionally, while the OECD definition of PFAS is broader than
                other entities' definitions of PFAS, EPA is aware of some TSCA chemical
                substances which would meet this rule's definition of PFAS but not
                OECD's. In comparing the universe of PFAS that would be subject to
                EPA's proposed definition and those substances captured by OECD's
                definition, EPA determined that some substances with halogens (e.g.,
                iodine, chlorine, bromine) on the same carbon as the CF or
                CF2 moiety would be in scope of EPA's proposed definition
                but not OECD's. Examples of substances which are considered PFAS under
                this rule's definition but not OECD's definition include 1-chloro-
                1,1,2,2-tetrafluoroethane (CASRN 354-25-6) or 1,2-dichloro-1,1,2,2-
                tetrafluoroethane (CASRN 76-14-2). Because all substances which were
                captured by the proposed definition are still captured in this final
                rule, EPA points out that adopting the OECD definition would still have
                excluded some substances that are captured by this rule's definition.
                 Many commenters also suggested that trifluoroacetyl fluoride (TFA;
                CASRN 354-34-7) should be included within the scope of this rule. Under
                this rule's definition of PFAS, TFA is not within scope. EPA believes
                TFA does not meet the threshold for reporting under TSCA section
                8(a)(7), as it is a short-chain molecule (C2) with only one
                terminal -CF3, and no other fluorine atom, unlike substances
                such as PFOA, PFOS, and GenX. TFA is naturally occurring in some
                instances or is produced as an environmental degradant of many other
                substances, especially those with only one terminal carbon (-
                CF3) (Refs. 23, 24, and 25). EPA understands that the
                manufacture of TFA would not always be considered ``manufactured for
                commercial purposes'' under TSCA, such as its production as an
                environmental degradant or its presence as a naturally-occurring
                substance, and therefore EPA would not receive any TSCA section 8(a)(7)
                reporting on those quantities. Additionally, as EPA has noted in
                responding to a request for testing on PFAS, TFA is ``a well-studied
                substance'' with ``relatively robust toxicity information available''
                (Ref. 25). Therefore, EPA believes that reporting on TFA under a TSCA
                section 8(a) rule (i.e., one in which the scope is limited to those
                substances manufactured for commercial purposes and does not include
                environmental degradants) is not warranted as such requirements would
                be ``unnecessary'' and
                [[Page 70534]]
                ``duplicative'' under TSCA section 8(a)(5)(A).
                 EPA also disagrees with commenters who expressed that the scope of
                substances reportable under this rule should be a discrete list and not
                a structural definition. EPA points out that other TSCA requirements
                have relied on a structural definition when appropriate (e.g., the
                LCPFAC SNUR defines covered substances using a structural definition
                (40 CFR 721.10536) (Ref. 7), and the polymer exemption rule for new
                chemical pre-manufacture notices (PMNs) defines covered PFAS polymers
                using structural definitions (40 CFR 723.250). As some commenters
                pointed out, reporting exemptions for both existing chemicals (e.g.,
                certain byproduct exemptions in the CDR rule) and new chemicals (e.g.,
                byproducts and impurities not listed on the Inventory) mean that EPA
                may be unaware of some substances which meet this definition of PFAS,
                and which would also meet the TSCA definition of ``chemical
                substance.'' Therefore, EPA has chosen to define the scope of covered
                substances for the purpose of this rule using a structural definition
                and not inadvertently limit the scope of reporting to a discrete list.
                B. What is the inclusion for articles?
                1. Summary of Public Input
                 Several commenters provided feedback on the inclusion of articles
                (whether imported or domestically produced) in the proposed reporting
                requirements.
                 Commenters who expressed support for the inclusion of articles in
                the proposed reporting requirements provided the following rationales:
                 It is necessary that EPA include articles in the scope of
                reporting requirements to better understand where PFAS are used in
                products and the extent of human exposure. Additionally, EPA has
                recognized that PFAS in articles can be released during use and
                disposal, and therefore it is necessary for EPA to gather this
                information.
                 Information on PFAS-containing articles is critical to
                states that are beginning to regulate PFAS-containing items.
                 Even if there are data gaps related to the presence of
                PFAS in articles, EPA would benefit from knowing the existence of these
                gaps, and therefore, EPA should move forward with requiring reporting
                on articles.
                 Congress has authorized inclusion of articles in the
                reporting requirements; reporting of ``known or reasonably
                ascertainable information'' is not an excessive burden. Commenters
                argued that excluding articles from the scope of the final rule would
                be inconsistent with Congressional intent.
                 The definition of ``chemical substance'' under TSCA is not
                incompatible with the inclusion of articles. Further, in other sections
                of TSCA, Congress specified distinct requirements for chemical
                substances depending on their presence in articles, though it did not
                do so in TSCA section 8(a)(7).
                 Commenters who suggested that EPA exempt articles from the proposed
                reporting requirements provided the following rationales:
                 The proposed requirements are at odds with regulatory
                practices; historically, EPA has not included articles in reporting
                requirements. Additionally, CDR does not include reporting on imported
                articles, and some commenters stated that EPA should be consistent with
                those requirements. Some commenters suggested that the reasons EPA has
                provided in the past for certain CDR exemptions, including imported
                articles, are relevant here (i.e., the potential for exposure to
                chemicals contained in articles is ``limited'') and encouraged EPA to
                incorporate an imported article exemption under this rule. Several of
                these comments also mentioned previous EPA actions, such as the TSCA
                Fees Rule and the phenol, isopropylated phosphate (3:1) (PIP (3:1))
                rule, in which EPA initially aimed to include articles but eventually
                changed course due to ``workability'' issues of including articles
                (Refs. 26 and 27).
                 EPA did not provide sufficient justification in the
                proposed rule for requiring article reporting, and there is no mandate
                in the FY 2020 NDAA for inclusion of articles. Commenters claimed that
                EPA underestimated or failed to account for the burden this reporting
                will have on article importers, and EPA is unable to accurately
                estimate how many importers this proposed rule would affect.
                 Under TSCA, the definition of ``chemical substance'' has
                not been interpreted to include articles which contain the chemical
                substance. Commenters argue that TSCA section 8 implementing
                regulations also distinguish ``articles'' from ``chemical substances.''
                 Requiring reporting on articles would place undue burden
                on industry and for manufacturers or importers to obtain the
                information EPA seeks is very difficult given the absence of historical
                PFAS reporting requirements. Commenters claimed that there will be
                significant data gaps if EPA requires article information, and that EPA
                will not be able to obtain the information it seeks. Additionally,
                reporting on articles going back ten years is impractical.
                 EPA has acknowledged that article manufacturers and
                importers likely will not have the information EPA seeks, and
                therefore, manufacturers and importers should be exempt. These
                commenters also cite their foreign suppliers' confidentiality or trade
                secret claims over their products and indicate that it is unlikely
                their suppliers will divulge the information necessary to comply with
                this rule.
                 Supply chains are too broad and requiring articles
                reporting will result in duplicative information, especially for more
                complex articles or finished products.
                 Neutral comments suggested that if EPA is going to require
                reporting on articles, they should require reporting for domestic
                article manufacturers only and not article importers, and that even
                beyond this rule, EPA should fully consider the complexities associated
                with collecting data on articles under TSCA. One commenter stated that
                EPA should consider focusing its reporting requirements on articles
                with the greatest potential for human exposure. The commenter offered
                as an example the differences between articles containing PFAS on its
                surface due to the properties that PFAS would impart on the product
                (such as carpets or cookware) and articles containing PFAS within
                resins of multi-component parts. The commenter suggested that EPA
                exclude articles containing PFAS unless the PFAS was intentionally
                added to the article due to properties imparted on the article.
                2. EPA's Response
                 EPA appreciates the broad interest in the general topic of
                requiring reporting on PFAS within articles (either imported articles
                or articles that are domestically produced). This topic was also
                discussed at length during the SBAR Panel, and EPA considered all
                public input on the proposed inclusion of PFAS-containing articles in
                this rule. EPA is finalizing the requirement to include PFAS-containing
                articles within the scope of this rule, to the extent that the
                manufacturer (including importer) of PFAS within articles knows or can
                reasonably ascertain the requested information. EPA disagrees with
                commenters who stated that the Agency does not have the authority to
                collect information on PFAS-containing articles given the language in
                the FY 2020 NDAA. While the FY 2020 NDAA did not explicitly direct EPA
                to collect data
                [[Page 70535]]
                on articles containing PFAS, the FY 2020 NDAA also did not explicitly
                prevent EPA from collecting information on PFAS-containing articles.
                Further, EPA notes that it is within the Agency's authority to collect
                information on chemical substances which are manufactured or imported
                through articles. Thus, the FY 2020 NDAA's direction to EPA to require
                data from PFAS manufacturers necessarily includes those PFAS
                manufactured (including imported) within articles. Although EPA has not
                typically included articles in some other TSCA section 8 reporting
                rules, the Agency both has the authority and has previously done so.
                Other TSCA rules, including other TSCA section 8 reporting rules (such
                as the Preliminary Assessment Information Reporting rule under TSCA
                section 8(a) (40 CFR part 712) and the TSCA section 8(d) Health and
                Safety Data Reporting rule (40 CFR part 716) include reporting on
                articles as needed for EPA to fulfill its responsibilities under TSCA.
                Additionally, EPA points out that the TSCA Fees and PIP 3:1 rules
                (Refs. 26 and 27) are authorized under separate sections of TSCA. This
                PFAS reporting rule was proposed and required under TSCA section 8(a),
                which authorizes EPA to require reporting and recordkeeping
                requirements of manufacturers and/or processors, to the extent such
                information is known to or reasonably ascertainable by the reporter.
                The requirements and compliance standards of the PIP 3:1 (use in
                article prohibition) (Ref. 27) and Fees (self-identification of
                manufacture) rules were different (Ref. 26).
                 EPA disagrees with the commenters that under TSCA, the definition
                of `chemical substance' ``cannot be and has never been interpreted to
                include articles that contain the regulated chemical substance.'' TSCA
                section 3(2) does not define ``chemical substance'' to exclude
                articles. Generally speaking, articles are manufactured goods or
                finished products--and the chemicals in them are subject to TSCA. The
                law is clear that when a chemical substance is manufactured (including
                imported into the United States) or is distributed or processed in the
                United States--whether in bulk form or in an article--it can be subject
                to regulation under TSCA. As such, EPA can and has imposed regulatory
                requirements on chemical substances in articles under TSCA. Further, no
                TSCA section 8 regulations exclude articles from the definition of
                ``chemical substances.'' While implementing regulations for other TSCA
                section 8 rules may exempt reporting for activities related to a
                covered chemical substance in an article (e.g., general reporting and
                recordkeeping provisions for TSCA section 8(a) information-gathering
                rules (40 CFR part 704) or the Chemical Data Reporting rule (40 CFR
                part 711)), there is no definitional distinction for a chemical
                substance depending on whether it is incorporated into an article;
                nothing says that an ``article'' is exclusive or distinct from a
                ``chemical substance.'' While the CDR rule has exempted the import of
                articles from reporting, the domestic manufacture of a chemical
                substance within an article is still subject to CDR. Further, EPA
                points out that the introductory paragraph of 40 CFR 704.5 for
                exemptions states this section is superseded by any TSCA section 8(a)
                rule that adds to, removes, or revises the exemptions described in this
                section. Thus, the commenters' reliance on precedent under 40 CFR part
                704 fails to acknowledge that EPA has long allowed for different
                exemptions (or lack thereof) to apply under different TSCA section 8(a)
                rules as appropriate.
                 EPA also disagrees with commenters' statements that reporting on
                articles would place undue burden on industry. EPA points out that the
                reporting standard of TSCA section 8(a) rules is limited to information
                which is known to or reasonably ascertainable by the manufacturer.
                Thus, if requested information is beyond that scope of known or
                reasonably ascertainable, the reporting entity would not be required to
                submit anything beyond indicating that such information is not known or
                reasonably ascertainable to them. In other words, this reporting
                standard is not a testing requirement; rather it asks reporters to
                share with EPA the information they already have (or can reasonably
                determine) on their manufactured and imported PFAS.
                 Regarding comments on the lookback period for article importers,
                EPA points out that the lookback period proposed is consistent with
                Congress's direction to EPA in TSCA section 8(a)(7). EPA is not
                changing the proposed requirement to provide any known or reasonably
                ascertainable information for the period beginning in 2011.
                 Regarding comments stating that requiring reporting on articles may
                result in duplicative information for complex articles or products that
                are re-imported, EPA disagrees that the information reported will
                result in duplicative information, especially given the reporting
                standard applicable to this rule. EPA acknowledges that some supply
                chains of manufacturers reporting under this rule are complex. However,
                EPA believes that information known to or reasonably ascertainable by
                an article manufacturer at the first instance the PFAS is imported into
                the United States is likely different than the scope of information
                known to an article importer farther down the supply chain who may re-
                import that PFAS later, as the article is incorporated into more
                complex articles or products. For instance, the person who imports a
                PFAS within an article in the first instance may have different worker
                exposure information to report than a person who may later re-import
                that PFAS-containing article as part of a more complex product. In
                another example, information related to the known industrial or
                consumer uses of a PFAS within an article may be clearer to the person
                who re-imports a PFAS within a larger complex product than it is to the
                person who first manufactured the PFAS within the article. Thus, EPA
                does not believe that the information requested of PFAS article
                manufacturers would be duplicative, given the different steps of a
                supply chain and manufacturing processes, and is requiring all PFAS-
                containing article manufacturers to report the requested data to EPA to
                the extent it is known or reasonably ascertainable. EPA also believes
                that applying the reporting requirements each time a PFAS is imported
                into the United States is consistent with TSCA's definition of
                manufacturing under TSCA section 3(9) (which means ``to import into the
                customs territory of the United States (as defined in general note 2 of
                the Harmonized Tariff Schedules of the United States), produce, or
                manufacture'') and the directive under TSCA section 8(a)(7). EPA also
                believes that if a PFAS is imported, exported, then re-imported,
                limiting the scope of reporting to just one instance of importation
                into the United States may result in certain burden on manufacturers
                within the supply chain who need to further communicate with each other
                to determine whether a PFAS within an article has already been reported
                and who is responsible for reporting. Further, with respect to comments
                claiming that the inclusion of articles will necessarily result in
                significant data gaps, EPA respectfully points out that there is no
                current database with comparable information on PFAS in commerce,
                including within articles, over the reporting timeframe. EPA cannot
                make an assessment of potential PFAS data gaps without considering all
                reasonably available information. Additionally, as noted by other
                commenters, EPA would benefit
                [[Page 70536]]
                from better characterizing any data gaps after receipt of all
                reasonably known information.
                 EPA disagrees with commenters' suggestions to limit the scope of
                reporting on PFAS in articles by extending reporting requirements to
                only those articles ``with the greatest exposure potential.'' For the
                purpose of a TSCA section 8 information reporting rule, there is no
                requirement for EPA to determine which substances or types of articles
                may pose greater exposure potential, unlike some other sections of TSCA
                (e.g., TSCA section 6 Significant New Use Rules). This TSCA section
                8(a)(7) rule in particular aims to provide EPA with a greater
                understanding of the scope of existing information of PFAS within the
                supply chain and the quantities and uses of commercially manufactured
                PFAS, which may include PFAS manufactured or imported within a variety
                of articles or products.
                 Finally, EPA took appropriate and necessary steps to consult with
                the public and consider stakeholder input on the proposed rule,
                including reporting on PFAS-containing articles. These steps included
                convening an SBAR Panel and meeting with stakeholders to discuss the
                proposed rule and potential reporting obligations. EPA has considered
                all input for this rule, including the complexity of different supply
                chains with respect to collecting data on articles. While EPA was not
                able to estimate the burden on article importers given the data
                limitations at the time of the proposed rule's publication, the Agency
                has since been able to provide such estimates, including input from
                public commenters, peer-reviewed journals, other government datasets,
                and input from the SBAR Panel. EPA has now remedied this omission in
                the Economic Analysis.
                C. What are the exclusion of processors from rule?
                1. Summary of Public Input
                 EPA received comments both in support of and in opposition to the
                addition of processors to the proposed rule. Ten commenters stated that
                EPA should expand the rule beyond manufacturers (including importers)
                to cover all facilities processing PFAS. Two of these commenters
                expressed that processors are often in the best position to provide the
                information required under TSCA section 8(a). Several commenters
                emphasized the importance of collecting information on the full life
                cycle of PFAS, including from processing operations. Some commenters
                were concerned with a potential data gap of PFAS exposures if
                processors are omitted from the final rule. Another commenter
                highlighted the importance of tracking the PFAS solid waste stream to
                enhance understanding of health risks associated with PFAS and to
                inform other actions under environmental regulations such as the Safe
                Drinking Water Act (SDWA) and Comprehensive Environmental Response,
                Compensation, and Liability Act (CERCLA). Many commenters in support of
                adding processors also stated that EPA has the authority to require
                reporting from processors, citing both the FY 2020 NDAA and TSCA
                section 8(a)(1).
                 Four commenters indicated that the Congress did not intend for the
                proposed rule to include processors and that EPA should not require
                them to report. Two of these commenters referred to the FY 2020 NDAA
                section 7351 language stating that the Act does not identify
                manufacturers that process PFAS substances as entities that would be
                subject to the rule. Commenters in opposition to adding processors also
                claimed that EPA would be creating confusion and the potential for
                duplicative reporting. One commenter urged EPA to clarify in the final
                rule that reporting is limited to only the initial importers of PFAS-
                containing products and not any downstream processors or users.
                Commenters also said that such reporting would create unnecessary
                burden for both EPA and processors.
                2. EPA's Response
                 EPA appreciates commenters' perspectives on extending reporting
                requirements to processors for this rule under TSCA section 8(a)(7).
                However, the Agency's reading of the text in TSCA section 8(a)(7) and
                the FY 2020 NDAA's legislative history conclude that the intended scope
                of this rule is to only require reporting from manufacturers (including
                importers), distinct from processors. EPA is clarifying that entities
                who solely process, distribute, and/or use PFAS, and do not manufacture
                (including import) PFAS for a commercial purpose, are not required to
                report under this rule.
                 As some commenters noted, the Agency would have the authority to
                promulgate such a rule for processors under TSCA section 8(a)(1).
                However, this rule is being promulgated under TSCA section 8(a)(7). EPA
                also notes that the exclusion of processors from the scope of this rule
                does not preclude any potential future rulemaking under TSCA section
                8(a)(1), should the Agency determine such data are needed. EPA will
                review the data submitted by manufacturers under this rule and reserves
                the right to promulgate a rule under TSCA section 8(a)(1) to capture
                information from PFAS processors if appropriate. EPA disagrees with
                commenters who noted that including processors in the scope of this
                rule would lead to confusion and duplicative reporting. EPA points out
                that other TSCA section 8(a) rules have included processors, such as
                the nanoscale materials reporting rule (40 CFR 740.20).
                D. What were the small business considerations?
                1. Summary of Public Input
                 Many commenters opined on the inclusion of small businesses,
                including small manufacturers, under the proposed rule. Several
                commenters stated that EPA should exempt small businesses from
                reporting under the proposed rule. Some of these commenters said that
                small businesses are not likely to provide useful information and will
                be disproportionately affected by the rule (including potentially being
                forced out of business) because fewer resources are available to them.
                Others expressed that they thought EPA had not evaluated whether small
                businesses would actually contribute meaningful data to EPA as a result
                of the rule.
                 Four commenters disagreed with EPA's position that the FY 2020 NDAA
                authorizes data collection from all manufacturers, including small
                manufacturers. Two of these commenters felt that, by not providing
                relief for small manufacturers, EPA did not appropriately apply TSCA
                section 8(a)(5) requirements. Some commenters referred to TSCA section
                8(a)(1), which they state excludes small manufacturers from reporting
                rules. Another commenter stated that EPA needs to consider the
                historical lack of TSCA section 8 reporting requirements on small
                manufacturers or article importers, including from CDR.
                 Other commenters said that EPA should collect the information
                required under the proposed rule from all businesses regardless of
                size. While one commenter acknowledged that the rule could be
                burdensome for small entities, they also said that the health risks
                associated with PFAS are significant and warrant the data collection
                from small businesses. Another commenter described EPA's definition of
                small manufacturer under TSCA section 8 as ``expansive'' and noted that
                the existing ``small manufacturer'' definition would
                [[Page 70537]]
                result in omitting reporting from significant PFAS manufacturing and
                importing activities such that it would undermine this data collection
                effort.
                 One commenter stated that EPA could help small businesses comply
                with the proposed rule in lieu of a small manufacturer exemption by
                extending other reporting exemptions to them, including R&D substances,
                non-isolated intermediates, impurities, byproducts, and articles, as
                well as a minimum reporting threshold.
                2. EPA's Response
                 EPA disagrees with commenters' positions that a broad small
                business or a small manufacturer exemption is appropriate for this
                rule. EPA appreciates that small businesses, especially those which
                have not previously reported under CDR or other TSCA section 8(a)
                rules, may not have the same resources that are available to large
                companies. This feedback was also voiced through the rule's SBAR Panel,
                and EPA is greatly appreciative of the input related to small
                businesses' resources and ability to respond to the rule. To that end,
                EPA has modified the proposed rule to include options that provide some
                relief to all manufacturers, including small entities. Specifically,
                article importers and manufacturers of R&D substances in quantities
                below 10 kilograms per year will have the option to submit more
                streamlined reporting forms than the longer, standard form for all
                other PFAS manufacturers. Additionally, EPA is extending the deadline
                for reporting forms by at least six months from what was proposed, so
                that all entities, including small entities, have 18 months from the
                effective date of this rule to submit the requested information. For
                small manufacturers (as defined at 40 CFR 704.3) whose reporting
                obligations under this rule are exclusively from article imports, EPA
                is further extending the deadline for reporting forms by an additional
                six months. Thus, small article importers have 24 months from the
                effective date of this rule to submit the requested information.
                 In response to commenters who refer to TSCA section 8(a)(1) in
                their support of an exemption for small manufacturers, EPA respectfully
                points out that this is a rule authorized under TSCA section 8(a)(7),
                not under TSCA section 8(a)(1). While Congress explicitly carved out
                potential exemptions for small manufacturers and small processors for
                rules implemented under TSCA section 8(a)(1) for chemicals not subject
                to certain TSCA actions, Congress chose not to do so in the text of
                TSCA section 8(a)(7). EPA considered the provisions at TSCA section
                8(a)(5) to limit reporting requirements for small manufacturers and
                determined that reporting from small manufacturers would be appropriate
                under TSCA section 8(a)(5)(A) through (C). The information requested
                under this rule is not unnecessary nor duplicative due, in part, to
                exemptions in other TSCA reporting rules. Additionally, a broad
                exemption for all entities deemed a ``small manufacturer'' would not
                enable EPA to fulfill the express requirements of the NDAA to require
                ``each person'' to report their PFAS manufacturing activities to the
                extent they know or can reasonably ascertain. Regarding the provision
                to minimize the cost of compliance on small manufacturers, EPA has
                identified regulatory alternatives to the proposed rule that reduce
                compliance costs without a complete exemption. Finally, based on public
                comments and input from the SBAR Panel, EPA believes that small
                manufacturers are likely to have information regarding commercially
                manufactured PFAS, which is relevant to the effective implementation of
                TSCA.
                E. What is the concern regarding a lack of common TSCA reporting
                exemptions or reporting threshold?
                1. Summary of Public Input
                 Many commenters opined on the proposed rule's lack of common TSCA
                reporting exemptions and a reporting threshold. Several commenters
                added that incorporating exemptions and/or a reporting threshold would
                make the proposed rule consistent with other TSCA rules such as CDR,
                Fees, PAIR, and PMN reporting (Refs. 20, 26, and 27). Commenters cited
                potential compliance challenges and reporting burden as the rationale
                for such exemptions, as they stated that the work involved in
                identifying, tracing, and reporting under the proposed rule is
                significantly increased without exemptions. Other commenters said that
                the lack of exemptions would significantly increase the number of
                substances for which reporting must occur as opposed to the 1,364 PFAS
                estimated in the proposed rule, as those only reflected those PFAS on
                the Inventory or subject to an LVE, yet those sources exempt several
                types of substances (e.g., impurities, byproducts, R&D substances).
                Another commenter said that these types of substances are not likely to
                result in exposure to humans or the environment, and that EPA has not
                articulated what the benefit of the additional data would be.
                 On the other hand, several commenters supported implementation of
                the proposed rule without any exemptions. They said that Congress
                intended for each person who manufactures a PFAS to be subject to the
                rule, without exemptions, and that incorporating exemptions would not
                be consistent with EPA's past approach for PFAS. Some commenters also
                pointed out the differences between the objectives of CDR and this PFAS
                reporting rule, stating that CDR's intent is to obtain initial
                screening information on a broad universe of chemicals, while this
                rule's aim is to collect information specifically on PFAS.
                2. EPA's Response
                 EPA appreciates the input from commenters on the impacts of not
                incorporating certain reporting exemptions or thresholds. EPA
                appreciates the support from commenters who supported promulgating the
                final rule without exemption and, after reviewing public input, has
                decided to finalize that aspect of the proposed rule.
                 EPA disagrees with commenters' requests to include many of the
                reporting exemptions found in other TSCA rules such as in PMN reporting
                and the Fees Rule (Refs. 20 and 26). EPA points out that, unlike the
                Fees Rule, the scope of this rule is information which is known to or
                reasonably ascertainable by the manufacturer (Ref. 26).
                 While this rule uses the same reporting standard as CDR and other
                TSCA section 8(a) rules, this rule is focused on improving EPA's
                knowledge of commercially manufactured PFAS and their uses, which
                includes chemicals of concern to human health and the environment.
                Therefore, EPA does not believe many of the same reporting exemptions
                used in other TSCA rules are warranted. As directed by the statute, EPA
                is requesting information on PFAS manufactured for a commercial purpose
                to the extent such information is known or reasonably ascertainable to
                the manufacturer. EPA also points out that, whether types of substances
                (such as non-isolated intermediates, impurities, or articles) are
                likely to result in human or environmental exposures is not a threshold
                that EPA needs to satisfy for requiring reporting on those substances
                under TSCA section 8(a)(7). EPA aims to better understand the scope of
                existing knowledge of the universe of historically manufactured PFAS
                and implementing certain exemptions may inadvertently lead to the
                omission of information known to or reasonably ascertainable to some
                manufacturers.
                [[Page 70538]]
                The information EPA receives through this rule will refine the Agency's
                understanding of certain exposure-related data of PFAS manufactured. If
                certain substances have not resulted in significant human and
                environmental exposures, then that would be reflected in the submitted
                information.
                 EPA appreciates the public input on the proposed rule's burden
                analysis, including additional information received during the proposed
                rule's comment period, the SBAR Panel, and the IRFA comment period. EPA
                has refined its economic analysis, including the estimated scope of
                covered substances and associated burden of determining whether
                reporting is required. Regarding commenters' claims that the estimated
                scope of covered substances may be significantly greater than estimated
                without certain exemptions, EPA points out that the exact challenge
                articulated by commenters justifies the lack of exemptions in this
                rule: the fact that stakeholders have questions surrounding the number
                of covered substances under this rule, including as impurities,
                intermediates, or R&D substances, reveals the lack of existing
                information of the universe of PFAS in commerce. EPA aims to better
                understand what manufacturers know or may reasonably ascertain
                regarding manufactured PFAS, and exempting substances that were not
                previously reported under other TSCA rules would hinder that effort.
                F. What is the application of the reporting standard?
                1. Summary of Public Input
                 EPA received many comments on the reporting standard proposed for
                this rule: information known to or reasonably ascertainable by the
                manufacturer. The majority of these commenters suggested that EPA
                revise their definition of ``reasonably ascertainable'' to assist
                businesses with compliance. Specifically, these commenters voiced
                concerns over the time spent to conduct compliance determination
                activities to satisfy the ``due diligence'' requirement of the
                reporting standard for many substances and products, and for which they
                do not anticipate information being readily available even after an
                extensive search. Commenters claimed that, for substances which have
                been historically exempt from other TSCA reporting requirements
                (especially imported articles), there is likely little if any
                information available, yet entities would still be required to perform
                due diligence and demonstrated they have examined each imported
                article.
                 However, other commenters largely supported EPA's proposed
                requirements. One commenter suggested that ``known and reasonably
                ascertainable'' should be broadly interpreted and that the proposed
                definition of ``known and reasonably ascertainable'' is consistent with
                definitions in TSCA recordkeeping regulations and should therefore be
                included, as is, in the final rule. Other commenters stated that the
                requirement for manufacturers to assess whether they know or can
                reasonably ascertain PFAS' presence in their articles is a modest cost
                that is outweighed by the benefits of the data to EPA and the public.
                 In addition, there were several comments requesting that EPA
                clarify or provide additional guidance on the reporting standard for
                this rule, including guidance tailored to article importers and what
                constitutes due diligence under this standard. Some suggestions
                included stipulating that the scope of a manufacturer's inquiry within
                their supply chain is limited to just immediate suppliers (i.e., no
                need to inquire multiple levels of their supply chain), and that if a
                supplier refuses to share information with a manufacturer, then the
                manufacturer need not inquire further and would not face EPA
                enforcement action. Some commenters also requested further
                clarification of the proposed requirement to submit ``reasonable
                estimates'' for certain data elements where actual data are not
                available.
                2. EPA's Response
                 EPA appreciates the input from commenters and the SBAR Panel
                related to the scope of information that may be known to or reasonably
                ascertainable by (KRA) PFAS manufacturers, including small article
                importers. EPA has incorporated the feedback into both the rule (e.g.,
                providing an option of streamlined reporting forms for article
                importers and manufacturers of small quantities of R&D substances who
                would not know the downstream processing, use, and disposal
                information) and this rule's accompanying guidance and instructions on
                applying the KRA standard.
                 Regarding manufacturers who have concerns over the due diligence
                expected under this rule, including those who believe they ultimately
                will not obtain any reportable information, EPA clarifies that there is
                no reporting or recordkeeping requirement if an entity has no relevant
                information. This rule does not itself require any company to maintain
                information upon which a decision not to report is based. Consistent
                with their own business practices, companies may elect to retain
                documentation of their conclusion that they were not subject to
                reporting requirements. While manufacturers and importers are expected
                to exercise ``due diligence'' in looking for reportable PFAS and
                information, that effort will look different for different entities.
                 EPA also acknowledges that it may not be within the scope of
                ``reasonably ascertainable'' to survey all articles and products,
                especially for article importers. In addition to the existing guidance
                on this reporting standard, EPA is providing guidance on this reporting
                standard with respect to article importers and other entities who may
                be exempt under other TSCA regulations (e.g., manufacturers of small
                quantities of R&D substances).
                 Regarding the suggestions that the rule should limit the scope of a
                manufacturer's inquiry of its supplier(s) to only information which the
                supplier does not claim as CBI or trade secret, EPA is enabling a joint
                submission option within the future reporting tool. Similar to one of
                the joint submission options in the CDR tool, a PFAS manufacturer whose
                supplier does not volunteer requested information, including the
                specific chemical identity of a PFAS imported from the supplier, would
                have the option to complete the PFAS reporting form to the extent
                information is known or reasonably ascertainable. The manufacturer
                would then initiate an email to its supplier via the CDX-based tool and
                request the supplier provide the necessary information to EPA, using a
                secondary reporting form, without needing to divulge to the reporting
                entity the specific chemical identity of the PFAS or the composition of
                the product. The tool will create an electronic record of the U.S.-
                based importer's attempts to contact the supplier and request
                information. Further, if the immediate supplier does not know the
                information, they may continue to send an email via the reporting tool
                to their own suppliers, in an effort to secure the requested
                information.
                G. What are the concerns regarding potential duplicative reporting?
                1. Summary of Public Input
                 EPA received comments on potential duplicative reporting under the
                proposed rule and NODA public comment periods. The majority of
                commenters shared the sentiment that the proposed reporting
                requirements
                [[Page 70539]]
                would result in duplicative reporting that is contrary to TSCA section
                8(a)(5)(A), which requires EPA to avoid, to the extent feasible,
                reporting which is unnecessary or duplicative. Most of these commenters
                shared the opinion that some information required to be reported under
                the proposed rule is extremely similar to, if not the same as,
                information required under the CDR rule. One commenter, however, shared
                a contrasting opinion that EPA should not exclude information
                previously reported under CDR requirements on the grounds that omitting
                that information would compromise EPA's ability to collect and
                aggregate PFAS data pursuant to TSCA section 8(a)(7).
                 The commenters who stated that the requirements in the proposed
                rule consist of duplicative reporting primarily cited reporting
                requirements under the CDR rule as justification for their position.
                Multiple commenters also cited studies submitted as unpublished health
                and safety studies under TSCA section 8(d) and the substantial risk
                notification requirements under TSCA section 8(e). One commenter
                claimed that EPA is likely already in possession of a considerable
                amount of PFAS information from studies submitted to EPA under new
                chemicals reporting (i.e., PMN and LVE applications) and TSCA section
                8(e) reporting. A few commenters also suggested that companies should
                not be required to collect and repeat data for past non-principal
                reporting years. Other commenters specified that EPA should limit
                reporting of information concerning environmental or health effects by
                excluding information that is publicly available, such as information
                published in scientific journals, as requiring reporting of this
                information would be unnecessary and duplicative.
                 Multiple commenters claimed that including articles in the required
                reporting would substantially increase duplicative reporting due to the
                number of entities an article may pass through, who would then all be
                required to report information on that chemical. Two commenters raised
                the issue of articles which are exported from and then reimported into
                the U.S. and asserted that the reporting of reimported articles would
                be considered duplicative reporting. To remedy this situation, a
                commenter suggested that EPA require reporting at the level of
                manufacturing the PFAS itself, and possibly the first supplier that
                incorporates a PFAS, but no further.
                2. EPA's Response
                 EPA acknowledges that some of the data elements may overlap with
                the data required under the 2020 CDR cycle but disagrees that the scope
                of such overlap is significant. There are several differences between
                the CDR rule and this rule which limit the scope of any potential
                overlaps between the datasets. First, CDR includes several reporting
                exemptions and a reporting threshold based on production volume, which
                are not included in this rule: imported articles, certain byproducts,
                non-isolated intermediates, small quantities of R&D chemicals, small
                manufacturers, and a minimum production volume reporting threshold of
                25,000 lbs/year (or 2,500 lbs/year for substances subject to certain
                TSCA actions). Therefore, PFAS reporters with activities that are
                exempt in CDR or who manufacture PFAS below the CDR threshold will not
                have reported such information to CDR before and would not be
                considered ``duplicative'' here. Further, CDR reporters may have
                excluded quantities that would be reportable under this rule, based on
                certain CDR exemptions, and therefore the information they previously
                submitted to CDR would not be considered duplicative and would not be
                responsive to this rule. Secondly, the PFAS that have been reported to
                CDR are a subset of the scope of PFAS for this rule. The scope of CDR
                chemical substances is limited to those on the Inventory and excludes
                polymers. The scope of this reporting rule includes any chemical
                substance meeting the rule's structural definition, which is not
                limited to those on the Inventory (e.g., LVEs), and includes any
                fluoropolymers that meet the structural definition. Finally, the years
                for which certain required data elements may have been reported to CDR
                differ. Some of the information described earlier in this unit is
                reported differently for the principal reporting year compared to the
                other three years within the four-year CDR period. For instance, the
                production volumes for domestic manufacture and import are combined for
                any non-principal reporting year. Further, prior CDR cycles had
                different required information. Therefore, the extent of potentially
                ``duplicative'' reporting between CDR and this rule is limited,
                especially when considering each year for which reporting is required
                under this rule.
                 EPA is finalizing the proposal to not require resubmission of
                information that has been reported to CDR, unless that information did
                not reflect all activities or quantities for which reporting is
                required under this rule. EPA disagrees with the commenter who
                suggested that EPA should not exclude information previously reported
                under CDR. Such information could be duplicative and therefore EPA is
                limiting that reporting under TSCA section 8(a)(5)(A).
                 EPA also appreciates the commenters' input regarding information
                previously submitted via TSCA section 8(e) reporting. EPA agrees that
                substantial risk notification requirements submitted to EPA under TSCA
                section 8(e) could be considered ``information concerning the
                environmental or health effects'' of a PFAS. To that end, EPA is
                finalizing the rule to acknowledge that manufacturers who have
                previously submitted substantial risk notifications, other unpublished
                health and safety studies under TSCA section 8(d), or other relevant
                information concerning environmental or health effects need not
                resubmit the information. However, to enable EPA to easily collect
                those prior submissions, the manufacturers must indicate the rule or
                program to which they submitted that prior information concerning the
                environmental or health effects of that PFAS and the year in which it
                was submitted to EPA. EPA also reiterates that manufacturers need not
                submit health and environmental effects information that is not in
                their possession or control, but could be found from a publicly
                available source.
                 Finally, regarding the comments related to whether reporting
                certain imported articles in complex products may lead to duplicative
                reporting: EPA disagrees that the information reported will result in
                duplicative information, especially given the reporting standard
                applicable to this rule. EPA believes that information known to or
                reasonably ascertainable by an article manufacturer at the first
                instance the PFAS is imported into the United States is likely
                different than the scope of information known to an article importer
                farther down the supply chain who may re-import that PFAS later, as the
                article is incorporated into more complex articles or products. EPA
                also believes that applying the reporting requirements each time a PFAS
                is imported into the United States is consistent with TSCA's definition
                of manufacturing and directive under TSCA section 8(a)(7). If a PFAS is
                imported, exported, then re-imported, then limiting the scope of
                reporting to just one instance of importation into the United States
                may result in certain burdens on manufacturers within the supply chain
                who need to further communicate with each other to determine whether a
                PFAS within an article has already been reported and who is responsible
                for reporting.

                H. What are the concerns regarding the lookback period?
                1. Summary of Public Input
                 Several commenters stated that attempting to obtain or develop the
                required information over a ten-year lookback period is not feasible
                and would constitute a significant burden to reporters, and they felt
                that EPA should eliminate or shorten the lookback period. These
                commenters suggested either setting the lookback period to either 3
                years, or 5 years to be consistent with the CDR recordkeeping
                requirement. Commenters stated that it would be difficult or impossible
                to collect the information required due to the complexities of their
                supply chains, the turnover rate of foreign suppliers especially for
                fad markets, the lack of historical reporting requirements for PFAS in
                products, and the concurrent supply chain disruptions rendered by the
                COVID-19 pandemic. Commenters also suggested that creating or
                recreating data from the lookback period will result in imprecise data.
                In addition to the suggestions to reduce the lookback period, some
                commenters suggested that EPA consider implementing a ``principal
                reporting year'' approach as used in CDR, in which only production
                volumes are reported for each year, while the more detailed data
                elements are reported for only the principal reporting year. Other
                suggestions included exempting articles or exempting companies that
                have since phased out PFAS by the reporting deadline.
                2. EPA's Response
                 EPA disagrees with the commenters who have suggested altering the
                lookback period from 2011 to a more recent year. The language in TSCA
                section 8(a)(7) directs EPA to promulgate a reporting rule for ``each
                person who has manufactured a chemical substance that is a [PFAS] in
                any year since January 1, 2011, to submit to the Administrator a report
                that includes, for each year since January 1, 2011, the information
                described in subparagraphs (A) through (G) of paragraph (2).''
                Congress's direction to EPA is clear: the lookback period for this
                reporting rule must begin on January 1, 2011. EPA understands the
                extent of information known to or reasonably ascertainable by a
                manufacturer may vary for several reasons. However, EPA's obligation
                under TSCA section 8(a)(7) and interest in identifying the scope of
                available and existing data on historically manufactured PFAS demand
                that PFAS manufacturers conduct their due diligence and submit
                requested information to the extent it is known or reasonably
                ascertainable.
                I. What is the submission period duration and reporting deadline?
                1. Summary of Public Input
                 EPA received significant input on the duration of the proposed
                submission period. Many commenters and input during the SBAR Panel
                claimed that the proposed rule's reporting deadline is unrealistic, and
                EPA should allow more time for reporting to accomplish the required
                data collection. Commenters provided a range of alternatives to
                consider for the reporting deadline, from 1.5 years from rule
                promulgation to 5 years from rule promulgation for article importers.
                 Several commenters provided detailed descriptions of the types of
                activities that would need to occur during the submission period as
                evidence of why they felt the proposed submission period to be
                inadequate. Some commenters raised EPA's experiences with the PIP (3:1)
                rule as justification for a longer time frame for extensive PFAS data
                reporting (Ref. 27). Other reasons provided by commenters regarding why
                additional time is needed include: time to familiarize themselves with
                the rule; unclear scope of requirements in the proposed rule; lack of
                systems in place with which to track the data leading to manual
                collection; and lack of ability to outsource the task to contractors
                due to the confidentiality concerns. In addition, one commenter noted
                that other jurisdictions have delayed the implementation of new rules
                in light of overwhelming burden, COVID, and supply chain disruptions.
                 EPA also received some comments urging the Agency to finalize this
                aspect of the proposed rule and not delay the deadline by which PFAS
                data are submitted. Commenters cited the pressing need for such data
                and the awareness within the regulated community of this rule.
                2. EPA's Response
                 EPA appreciates the significant feedback the Agency received from
                the public, including through the SBAR Panel, on the duration of the
                reporting submission period. After considering input from the
                commenters and other stakeholders, EPA agrees that the proposed
                reporting time frame may not be sufficient for identifying, collecting,
                and reporting the scope of information requested by this rule. While
                EPA disagrees that the extent of activities necessarily requires
                investigations of the supply chain that would take up to five years to
                complete, it is modifying the proposal by adding six more months to the
                information collection period ahead of the reporting tool opening (for
                a total of one year from the effective date of this rule). This one-
                year information collection period will then be followed by a six-month
                reporting submission period. Thus, information will be due 18 months
                following the effective date of this rule for all PFAS manufacturers
                except certain small article importers. EPA has provided an additional
                six months for small manufacturers (as defined at 40 CFR 704.3) who
                would report exclusively article importers for the purposes of this
                rule. Therefore, small article importers have two years from the
                effective date of this final rule to report. Thus, information will be
                due 24 months following the effective date of this rule for small
                manufacturers (per 40 CFR 704.3) who are reporting exclusively as
                article importers. EPA believes this timeframe will be sufficient to
                allow reporters to familiarize themselves with the rule, identify PFAS
                they have produced or imported, identify any suppliers or other
                contacts, collect information, and submit the information to EPA. The
                additional time will enable reporters to thoroughly review their known
                or reasonably ascertainable information and provide EPA with the extent
                of the requested information under this reporting standard.
                 Additionally, as this is a TSCA section 8(a) reporting rule, EPA
                disagrees with commenters who request additional reporting time by
                comparing this rule to the PIP (3:1) rule or other non-section 8
                reporting rules (Ref. 27). The reporting standard under TSCA section
                8(a) does not apply to those rules, which may require additional
                compliance activities. However, EPA agrees with commenters who pointed
                out the distinctions between this rule and CDR as a basis for extending
                the reporting period: the CDR rule requires only a four-year lookback
                period, includes certain exemptions and reporting thresholds, different
                data elements, and is regularly occurring so that companies can
                anticipate reporting. Due, in part, to these differences with CDR, EPA
                is extending the information collection period ahead of the submission
                period, thereby providing reporters with 18 months to submit
                information for this rule (or 24 months for small article importers).
                 EPA disagrees with commenters who have suggested the reporting
                deadline should be sooner than what was proposed. EPA appreciates the
                commenters' interest in reviewing the submitted PFAS data as soon as
                [[Page 70541]]
                possible, but notes the scope of this rule and differences between this
                rule and CDR as factors in allowing the reporting community extra time
                to sufficiently review their known or reasonably ascertainable
                information and to submit the required data to EPA.
                J. Can joint submissions be allowed?
                1. Summary of Public Input
                 Some commenters requested that EPA allow joint submissions. They
                suggested it might ease the reporting burden and simplify the reporting
                process while still protecting CBI. However, other commenters stated
                that joint submissions can still be a substantial burden for companies
                already trying to complete their own reporting within a prescribed
                timeframe. Commenters urged EPA to carefully consider a workable
                solution to protecting CBI and reducing industry burden for compliance.
                In response to the NODA, one commenter asked EPA to eliminate the
                requirement for joint submissions in response to chemical identity CBI
                concerns.
                2. EPA's Response
                 EPA agrees with the commenters' requests for joint submissions and
                is finalizing this requirement for reporters (other than article
                importers) whose suppliers do not wish to disclose chemical identity.
                EPA agrees that such an approach would help protect suppliers' CBI
                while not withholding necessary information from EPA related to PFAS
                identity. While this may increase burden on upstream companies, EPA
                believes this approach will both help downstream manufacturing and
                reporting entities, as well as protect CBI if the suppliers do not wish
                to disclose it to their customers, including reporting entities.
                K. What are the economic analysis considerations?
                1. Summary of Public Input
                 Many commenters addressed the impact of the proposed rule in
                general: on industry, EPA, and the general public. Several commenters
                provided input on the industry burden estimates provided in EPA's draft
                Economic Analysis for the proposed rule, with many stating that EPA
                underestimated the cost industry would incur to comply with the
                proposed rule and failed to include article importer costs. Commenters
                provided specific feedback on EPA's burden and cost estimates for
                certain activities including rule familiarization, CBI substantiation,
                article identification, determination of chemical identity,
                identification of byproducts, outreach to suppliers, data collection,
                CDX access and training, form completion and recordkeeping. Some of
                these commenters provided additional data or factors to consider when
                estimating burden or costs for these compliance activities, including
                providing results of their own industry surveys. Commenters also
                provided specific feedback on the proposed rule's burden on article
                importers and stated that EPA's draft burden assessment is
                significantly underestimated. Some commenters stated that article
                importers may face substantially more costs than domestic producers
                because they lack the knowledge needed for compliance yet would still
                incur costs under the reporting standard. Additionally, because article
                importers do not have experience with CDR, commenters believed their
                cost would be higher than EPA's draft estimates which used CDR to
                extrapolate burden estimates for this rule.
                 Some commenters also claimed that EPA's use of CDR burden to derive
                burden estimates under this rule was inappropriate due to the
                differences between the two rules. Commenters also provided feedback on
                the estimated number of substances subject to reporting in the draft
                Economic Analysis and claimed that the draft estimates were too low.
                Some commenters pointed out that, because the proposed rule does not
                have the same exemptions as CDR nor is limited to a discrete list of
                substances, the number of substances subject to reporting would be
                substantially higher than the estimates provided in the draft Economic
                Analysis.
                 EPA also received comments that the proposed rule significantly
                underestimated the universe of small entities that would be subject to
                the rule, both due to the lack of estimates related to article
                importers and to the extrapolation from CDR data. Some commenters
                described the unique difficulties or burdens small businesses face when
                complying with the proposed rule compared to larger businesses.
                Commenters stated that EPA cannot justify an RFA certification without
                further analysis of the small business impacts and requested that EPA
                convene an SBAR Panel under the RFA to obtain feedback from small
                businesses potentially affected by the rule.
                 Some commenters also stated that EPA's draft Economic Analysis
                underestimated burden on the Agency itself. Namely, the need to
                increase CDX capacity to handle the number of reporting forms and other
                administrative costs of reviewing the submitted data are not reflected
                in the draft Economic Analysis.
                 Finally, other commenters claimed that EPA had not accounted for
                the social and health costs associated with PFAS exposure in the burden
                analysis. Commenters added that the public and various government
                entities have incurred significant health, social, and financial costs
                due to inadequate information related to PFAS, and that even an
                underestimation of industry compliance costs for this rule are minimal
                compared to the externalized costs that the public and governments bear
                related to PFAS exposure and remediation.
                2. EPA's Response
                 EPA appreciates the feedback on the draft Economic Analysis and
                agrees with commenters that an SBAR Panel was appropriate given the
                limitations of data related to the small entity universe at the time of
                the proposed rule's publication. Accordingly, EPA convened an SBAR
                Panel for this rule in April 2022 and completed it in August 2022.
                Using feedback from commenters, input during the SBAR Panel, and
                additional data made available to EPA since the proposed rule's
                publication, EPA has since accounted for the burden that the rule would
                impose on article importers and small entities. The burden estimates
                include the number of article importers who will be required to report
                as well as the number of entities that will have to assess their
                product lines to determine whether they must submit reports. EPA
                disagrees that the article importer compliance determination activities
                are too low. EPA recognizes that a range of activities may be involved
                depending on the level of experience of the importer. Actual costs may
                vary based on the number of articles imported, the complexity of the
                articles, the number of suppliers, and the frequency of supplier
                changes. EPA has increased the rule familiarization costs as well as
                included the burden of understanding the structural definition of PFAS.
                Readers are referred to EPA's updated Economic Analysis for details
                regarding the assumptions of calculating burden and costs for article
                importers and small entities.
                 With regards to the use of CDR data, EPA acknowledges that CDR data
                are subject to reporting thresholds and that the CDR universe does not
                reflect a perfect representation of the likely reporting universe of
                this rule. EPA recognizes the limitations of using CDR data in
                estimating the burden, including the number of PFAS for which companies
                may ultimately report. However, there is no comprehensive

                database of PFAS manufactured in the U.S. that EPA could use to develop
                more precise estimates. The reporting requirements of this rule will
                serve to fill this knowledge gap. After considering input from the
                proposed rule's public comments, stakeholders in the SBAR Panel, and
                comments received on the IRFA, EPA is continuing to rely on the CDR
                data to extrapolate the estimated number of PFAS to be reported per
                firm. EPA acknowledges that the number may vary for some manufacturers
                but believes that using CDR for such estimates will help provide an
                industry average.
                 EPA has updated the Agency costs to account for the volume of
                reports that will be submitted. EPA will incur costs in administering
                the final rule associated with processing submitted reports, analyzing
                data from the reports, maintaining the information technology systems
                that support these activities, reviewing CBI claim substantiations, and
                information technology infrastructure.
                 Finally, with regard to the comments that EPA has not accounted for
                social and health costs associated with PFAS, EPA points out that this
                rule is a TSCA section 8(a) reporting and recordkeeping rule and does
                not impose any restrictions or other chemical management requirements.
                While the benefits of this rule include additional information related
                to potential PFAS exposure, which will help inform future regulatory
                and research activities, EPA cannot quantify those benefits at this
                time, though the Agency discusses them qualitatively in the Economic
                Analysis.
                L. What are the CBI claim submission requirements?
                1. Summary of Public Input
                 Several commenters submitted comments regarding reporting
                requirements in the proposed rule and EPA's intended approach to
                reviewing CBI claims as stated in the NODA. Their comments generally
                fell into two categories: (1) Urging EPA to protect CBI and simplify
                electronic reporting to allow joint submissions when needed, in
                addition to making substantiation procedures for CBI claims more
                simplified, and not allowing reporters without knowledge of a specific
                chemical identity to waive a CBI claim for that chemical identity; and
                (2) Urging EPA to require valid and well-explained rationale for any
                CBI exemptions, and generally asking EPA to disclose as much
                information to the public as possible. Some commenters also cited
                concerns with the proposed rule's CBI protections as being inadequate
                for R&D activities, including those in the defense or national security
                industries. Some commenters requested that the Agency allow a ``blanket
                substantiation'' for all CBI claims so that reporters would not be
                required to substantiate each individual CBI claim.
                 On the other hand, commenters who are supportive of limiting the
                amount of information claimed as CBI (especially regarding health and
                safety studies) cited the urgent need for states to address their own
                PFAS exposure and contamination issues and the benefit that this rule
                will confer on state agencies struggling with inadequate PFAS
                information. These commenters encouraged EPA to review claims and
                disclose as much information submitted under this rule as possible.
                 Commenters during the NODA comment period also addressed EPA's
                proposal to require that any PFAS generic name include ``fluor,'' at
                minimum, and EPA's proposal to determine that failure to stipulate that
                a chemical for which the identity is being claimed as CBI is
                fluorinated would be an insufficient claim. Some commenters were
                supportive of such requirements; other commenters discouraged EPA from
                implementing this requirement as it may create confusion. Finally,
                commenters diverged on EPA's intent to move any PFAS identity to the
                public TSCA Inventory without prior notice if it is not claimed as CBI.
                While some commenters supported this approach, others described
                potential complications of confidential chemical identity protection
                when multiple entities submit reports for the same substance, some of
                whom may not assert CBI for the identity, and requested that EPA notify
                all claimants of a potential change in CBI status for a chemical
                identity and allow appeal opportunities.
                2. EPA's Response
                 EPA does not believe that an option for blanket CBI claims
                substantiation is appropriate for an information collection rule such
                as this one, in which several types of information are requested. TSCA
                section 14(c) requires substantiation specific to each claim. Because
                the type of information requested under this rule varies, a blanket
                substantiation is unlikely to address the specific reasons for each
                data element claimed as CBI. The more generic a substantiation gets,
                the less support it provides for any specific claim. In terms of
                information disclosure, EPA is committed to reviewing CBI claims and
                substantiations pursuant to TSCA section 14 and implementing
                regulations, and publicly disclosing data that are not approved as CBI
                to the extent possible.
                 As noted in the preamble of the proposed rule, TSCA limits
                confidentiality protections for health and safety studies, and
                information from health and safety studies (except to the extent such
                studies or information reveals ``information that discloses processes
                used in the manufacturing or processing of a chemical substance or
                mixture or, in the case of a mixture, the portion of the mixture
                comprised by any of the chemical substances in the mixture'').
                Submitters asserting a confidentiality claim for such information in
                health and safety studies are also required to submit a sanitized copy
                of the study, removing only that information which is claimed as CBI
                and that discloses the process or portion of mixture information
                described in TSCA section 14(b). However, certain other information
                within study reports may be claimed as CBI, such as the names of lab
                personnel or the company, or other information that is not related to
                health or environmental effects.
                 In response to requests for EPA to work directly with states on
                disclosing CBI submitted under this rule, EPA points out that TSCA
                section 14(d)(4) permits states, tribes, and political sub-divisions of
                states to request access to CBI in writing. Under this authority, the
                entity seeking CBI access must show that it can continue to protect the
                information as confidential. If a state or tribe requests access and
                that is granted per statutory conditions, EPA would have an agreement
                in place laying out how the requestor was going to protect the
                information.
                 In response to comments on the CBI procedures described in the
                NODA, EPA is not requiring article importers to assert CBI for the
                chemical identity and will not make public any chemical identity based
                on article importer submissions alone (see discussion in Unit III.G).
                Further, EPA acknowledges some commenters' concerns that multiple
                manufacturers may report the same PFAS, but not all submitters may
                assert a CBI claim for the PFAS identity. EPA will publish a list of
                Accession numbers associated with chemical identities that it plans to
                move to the public portion of the Inventory because either no chemical
                identity CBI claim was asserted or the claim was denied. Publication of
                these Accession numbers will provide entities an opportunity to contact
                EPA with questions or concerns before specific chemical identities are
                moved to the public Inventory (see Unit III.G for more details on this
                process). Finally, EPA believes that requiring ``fluor'' in generic
                name submissions is
                [[Page 70543]]
                consistent with PMN reporting requirements which provide that a generic
                name ``should reveal the chemical identity of the substance to the
                maximum extent possible'' (40 CFR 720.85(a)(3)(i)(B)), and is
                finalizing this requirement as discussed in the NODA (Ref. 1).

                 Additional information about these statutes and Executive orders
                can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.
                A. Executive Orders 12866: Regulatory Planning and Review and 14094:
                Modernizing Regulatory Review
                 This action is a ``significant regulatory action'' as defined under
                section 3(f)(1) of Executive Order 12866 (58 FR 51735, October 4,
                1993), as amended by Executive Order 14094 (88 FR 21879, April 11,
                2023). Accordingly, EPA submitted this action to the Office of
                Management and Budget (OMB) for Executive Order 12866 review.
                Documentation of any changes made in response to the Executive Order
                12866 review is available in the docket. EPA prepared an analysis of
                the potential costs and benefits associated with this action. This
                analysis, entitled ``Economic Analysis for the Final TSCA Section
                8(a)(7) Reporting and Recordkeeping Requirements for Perfluoroalkyl and
                Polyfluoroalkyl Substances'' (Ref. 1), is also available in the docket
                and is briefly summarized in Unit 1.E.
                B. Paperwork Reduction Act (PRA)
                 The information collection requirements in this rule will be
                [[Page 70544]]
                submitted for approval to OMB under the PRA, 44 U.S.C. 3501 et seq. The
                Information Collection Request (ICR) document that EPA prepared has
                been assigned the EPA ICR No. 2682.02 (Ref. 28) and the OMB Control
                number 2070-0217. You can find a copy of the ICR in the docket for this
                action, and it is briefly summarized here. The information collection
                requirements are not enforceable until OMB approves them.
                 The reporting requirements identified in the rule will enable EPA
                to meet the statutory obligations required by TSCA section 8(a)(7) and
                collect data related to the identities, manufacture, use, exposure, and
                disposal of PFAS manufactured in the United States since 2011. These
                one-time reporting requirements will also help the Agency to collect
                existing information on the health and environmental effects of PFAS.
                EPA intends to use information collected under the rule to assist in
                chemical assessments under TSCA, and to inform any additional work
                necessary under environmental protection mandates beyond TSCA.
                Respondents may claim some of the information reported to EPA under the
                rule as CBI under TSCA section 14. TSCA section 14(c) requires a
                supporting statement and certification for confidentiality claims
                asserted after June 22, 2016.
                 Respondents/affected entities: PFAS manufacturers (including
                importers). See Unit I.A.
                 Respondent obligation to respond: Mandatory. TSCA section 8(a) and
                40 CFR part 705.
                 Total estimated number of respondents: 131,410.
                 Frequency of response: One time.
                 Total estimated burden: 3,878,744 hours (per year). Burden is
                defined at 5 CFR 1320.3(b).
                 Total estimated cost: $281 million (per year) and $266.7 million
                (per year) using a 3 percent and 7 percent discount rate, respectively,
                which includes no annualized capital or operation and maintenance
                costs.
                 An agency may not conduct or sponsor, and a person is not required
                to respond to, a collection of information unless it displays a
                currently valid OMB control number. The OMB control numbers for the
                EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB
                approves this ICR, the Agency will announce that approval in the
                Federal Register and publish a technical amendment to 40 CFR part 9 to
                display the OMB control number for the approved information collection
                activities contained in this final rule.
                C. Regulatory Flexibility Act (RFA)
                 Pursuant to the RFA, 5 U.S.C. 601 et seq., EPA prepared an IRFA for
                the proposed rule and convened an SBAR Panel under RFA sections 603 and
                609(b) to obtain advice and recommendations from small entity
                representatives that potentially would be subject to the rule's
                requirements. Summaries of the IRFA and Panel recommendations are
                presented in the proposed rule's NODA (Ref. 1).
                 As required by RFA section 604, EPA prepared a final regulatory
                flexibility analysis (FRFA) for this action. The FRFA addresses the
                issues raised by public comments on the IRFA for the proposed rule. The
                complete FRFA is available for review in the docket (Ref. 29) and is
                summarized here.
                 Statement of need and rule objectives. Section 7351 of the
                FY2020 NDAA amended TSCA by adding section 8(a)(7), which obligates EPA
                to promulgate a rule by January 1, 2023, that requires each person who
                has manufactured PFAS in any year since 2011 to report and maintain
                records, for each year, information described in TSCA section
                8(a)(2)(A)-(G). This includes a broad range of information, such as
                information related to chemical identity and structure, production,
                use, exposure, disposal, and health and environmental effects. In
                addition, EPA believes that the collected data may help provide more
                information about PFAS manufacture, and to the extent that new
                information indicates the presence of negative externalities or data
                gaps, inform future agency actions and/or legislation governing the
                manufacture, processing, use, and disposal of PFAS.
                 EPA developed this final rule after considering findings from
                information provided in public comments on the proposed rule, findings
                from and comments on the SBAR Panel, and public comments on the IRFA.
                The final rule requires all manufacturers of PFAS in any year since
                2011 to report certain information to EPA related to chemical identity,
                categories of use, volume manufactured, byproducts, environmental and
                health effects, worker exposure, and disposal (i.e., the TSCA section
                8(a)(2)(A)-(G) requirements). This rule also requires a five-year
                retention period for all relevant records following the submission
                period.
                 Significant comments on the IRFA. In response to the IRFA
                and notice of data availability, EPA received 44 unique comments in the
                docket. EPA has provided a comprehensive summary of all comments
                received and EPA's responses in a supporting document that is included
                in the docket for this rulemaking (Ref. 21; see Part 2).
                 SBA Office of Advocacy comments and EPA response. EPA
                received comments from SBA's Office of Advocacy on the proposed rule
                and the IRFA. SBA's comments and EPA's responses are in the Responses
                to Comments document for this rule (Ref. 21) and in the FRFA (Ref. 29).
                SBA comments that led to changes to the proposed rule, and EPA's
                responses to those comments, are also summarized in this unit.
                 Comments: EPA has improperly certified the rule under the RFA. EPA
                should convene a Small Business Regulatory Enforcement Fairness Act
                (SBREFA) Panel and consider burden-reducing compliance flexibilities
                for small businesses. Additionally, EPA underestimated the impact of
                compliance costs associated with the proposed reporting requirements.
                 Response: EPA initially certified the proposed rule under the RFA
                based on all information available to it at the time of proposal.
                However, after receiving additional information related to the scope of
                small entities (including article importers) potentially impacted by
                the proposed rule, EPA updated its estimated scope of the universe of
                small entities potentially affected (including article importers) and
                the small entity compliance costs. Thus, EPA convened an SBAR Panel in
                April 2022. The Panel concluded in August 2022, and EPA subsequently
                published the Panel Report, updated Economic Analysis, and IRFA for
                public comment in November 2022. Input received through the Panel and
                during the subsequent comment period for the IRFA were considered in
                the development of this final rule, including comments related to EPA's
                small entity analysis. As a result of public input, EPA identified
                certain regulatory alternatives to the proposed rule, which EPA is
                implementing in the final rule: streamlined reporting forms for article
                importers and for manufacturers of low quantities of R&D substances;
                extending the reporting deadline; providing additional guidance on the
                TSCA section 8(a) reporting standard for article importers. These
                modifications to the proposed rule reduce compliance costs without a
                complete exemption of small entities. EPA has not made a determination
                that a complete exemption of small entities is not legally viable in
                this rulemaking. EPA believes such an exemption would result in
                diminished collection of reasonably known or ascertainable information
                about PFAS manufacturing and import
                [[Page 70545]]
                since 2011 and therefore is exercising its discretion to not implement
                this alternative. EPA estimates that each manufacturer would incur
                $2,240 in costs to complete the streamlined R&D form and $41,850 in
                costs to complete the general reporting form. Thus, incurring a total
                of $44,089 in costs per firm for form completion, compared to $52,739
                without the streamlined form. For the streamlined form for article
                importers, EPA estimates that each article importer will incur an
                average of approximately 91.7 burden hours and $7,531 in costs per
                firm. Without a streamlined reporting form, EPA estimates that each
                article importer would incur an average of approximately 168 burden
                hours and $13,818 in costs for form completion. Additionally, extending
                the reporting deadline may reduce the opportunity costs if firms are
                diverting resources from other business activities to report
                information under the rule. This may be particularly true for small
                entities. See Table 24 for more information on the costs associated
                with the finalized option and alternatives identified in the IRFA (Ref.
                23).
                 Estimate of the number of small entities to which the
                final rule applies. This final rule will impact PFAS manufacturers,
                including article importers, across a broad number of industries,
                including the following: utilities; construction; manufacturing;
                wholesale and retail trade; and some waste management. Entities who
                solely process, distribute, and/or use PFAS, and do not manufacture
                (including import) PFAS, are not covered. EPA estimates that
                approximately 97% of all firms potentially affected by this rule would
                meet the SBA standard of ``small business,'' for a total of 128,051
                affected small entities. It is expected that all 128,051 firms will
                undertake structural definition familiarization, some rule
                familiarization activity, and compliance determination, including
                article importers that do not report under this rule. However, EPA does
                not assume that all potentially affected firms will ultimately have
                known or reasonably ascertainable information to report, so 13,021
                small entities are estimated to report under this rule.
                 Reporting, recordkeeping, and other compliance
                requirements of the final rule.
                 i. Compliance requirements. Pursuant to TSCA section 8(a)(7), EPA
                is finalizing this reporting and recordkeeping rule for entities who
                have manufactured a PFAS in any year since January 1, 2011. For each
                year since January 1, 2011, PFAS manufacturers (including importers)
                are required to report the following types of information for each PFAS
                to the extent it is known or reasonably ascertainable: chemical
                identity, production volume, categories of use, byproducts, worker
                exposure, disposal practices, and existing information concerning
                environmental or health effects. In instances where reporters have
                already submitted the requested information to EPA under certain
                reporting programs, they will not be required to re-report. The
                reporters will simply indicate they have already submitted such
                information to EPA. The reporting deadline is 18 months following the
                effective date of this rule, except for small manufacturers (defined at
                40 CFR 704.3) whose reporting obligations exclusively arise from
                article imports; the latter's reporting deadline is 24 months following
                the effective date of this rule. The reporting deadline is then
                followed by a five-year recordkeeping period.
                 ii. Classes of small entities subject to the compliance
                requirements. The small entities that are potentially affected by this
                rule are manufacturers (including importers) who have manufactured
                (including imported) PFAS in any year since January 1, 2011. This
                includes entities who have imported articles containing PFAS in any
                year since January 1, 2011.
                 iii. Professional skills needed to comply. Understanding some of
                the reporting requirements may involve special skills or expertise,
                though hiring or contracting such skills specifically for this rule are
                not required to comply, given the TSCA section 8(a) reporting standard
                of ``known or reasonably ascertainable.'' For example, understanding
                the rule's structural definition of PFAS and other reporting
                requirements may involve special expertise of chemistry. EPA assumes
                that chemical manufacturing and importing firms and large article
                importers will have staff with the technical knowledge to understand a
                structural definition more easily than small article importers. Based
                on input from the Small Entity Representatives, EPA estimated the cost
                of small article importer firms contracting outside help to understand
                the chemical structural definition, despite it not being a necessary
                step for compliance. Small article importers that contract outside help
                (which is not required for this rule's compliance) would incur $1,212
                in structural definition compliance costs, while small article
                importers that do not contract outside help would incur approximately
                $831. Additionally, environmental and health effects data may require
                some technical knowledge to report.
                 Steps taken to reduce economic impact to small entities.
                 i. Small Business Advocacy Review Panel. As required by RFA section
                609(b), EPA convened an SBAR Panel to obtain advice and recommendations
                from small entity representatives that potentially would be subject to
                the rule's requirements. A copy of the full SBAR Panel Report (Ref. 22)
                is available in the docket. The comments received on the proposed rule,
                the IRFA and EPA's responses to those comments are summarized in Unit
                IV and in further detail in the Response to Comments document in the
                docket (Ref. 21).
                 ii. Alternatives considered. EPA considered a wide variety of
                alternatives to the proposed rule. EPA considered the impact (both cost
                and in anticipated reporting) of providing exemptions for all small
                businesses, or a portion of small businesses (e.g., small article
                importers, small manufacturers using the TSCA section 8 definition, or
                entities below various sales thresholds). EPA also evaluated the impact
                of exemptions for certain substances, including imported articles,
                byproducts, impurities, non-isolated intermediates, and R&D substances.
                EPA also evaluated the impact of implementing a production volume-based
                reporting threshold in this rule. For each of these alternatives, EPA
                found that it would reduce the amount of PFAS reporting of reasonably
                known or ascertainable information from PFAS manufacturers (including
                importers) under TSCA section 8(a)(7). The amount of reporting that
                certain alternatives would reduce varied, ranging from exempting
                approximately 91% of all potentially covered firms from reporting under
                a small manufacturer exemption for any firm with under $12 million in
                sales (which would have resulted in a final rule costing small
                businesses approximately $48.8 million under a 7 percent discount
                rate), to exempting 69% of firms (all article importers) under an
                exemption for just article importers with sales below $2 million (which
                would have resulted in a final rule costing small businesses
                approximately $229.5 million under a 7 percent discount rate). EPA also
                considered applying a production volume reporting threshold of both
                2,500 lbs per year and 25,000 lbs per year, to align with CDR reporting
                thresholds. Because the amount of reporting and burden under a
                reporting threshold was difficult to estimate with existing data, EPA
                conducted sensitivity analyses for this alternative, based on the
                estimated number of PFAS article
                [[Page 70546]]
                importers who would be able to determine whether they are below the
                reporting threshold. On the low-end estimate for this alternative
                (i.e., 5% of affected article importers import PFAS-containing articles
                above threshold), EPA estimates that total number of PFAS reports
                submitted would decrease by 49 percent, and total small business costs
                would be approximately $736.6 million under a 7 percent discount rate.
                On the high-end (i.e., 9.5% of affected article importers import PFAS-
                containing articles above threshold), EPA estimates the total number of
                PFAS reports submitted to decrease by 5%, with total small business
                costs of $785.2 million under a 7 percent discount rate. Given the
                reduced reporting expected under alternatives including various
                exemptions and reporting thresholds, EPA determined that implementing
                such alternatives contradicted EPA's mandate under section 8(a)(7) to
                collect information from ``each person'' who had manufactured a PFAS.
                Further, while EPA recognizes there is a tradeoff between rule
                compliance costs and information collection, PFAS exposure presents
                significant human health and environmental concerns that it is critical
                for EPA to collect as much existing information on PFAS presence in
                commerce (including through disposal) as possible.
                 In addition to alternatives related to reporting exemptions and
                reporting thresholds, EPA considered limiting the scope of PFAS subject
                to this rule to a finite list, rather than a structural definition.
                This alternative simplifies rule familiarization for affected entities
                and removes the cost and burden of understanding the structural
                definition of PFAS. Additionally, it reduces compliance determination
                costs for affected firms. However, this also significantly limits the
                number of PFAS subject to the rule and excludes many PFAS that cannot
                be listed due to CBI claims but are active in U.S. commerce. If EPA
                limited the scope to a discrete list of PFAS on the TSCA Inventory and
                LVEs that could be specifically named under the final definition, 602
                PFAS would be subject to the rule. This alternative would result in an
                estimated 50% decrease in reporting forms submitted, along with an
                estimated small business cost of approximately $626.4 million under a 7
                percent discount rate.
                 However, EPA also considered alternatives to the proposed rule that
                the Agency is finalizing to reduce burden on small entities. EPA
                considered providing streamlined reporting form options for both
                imported articles and R&D substances manufactured in low quantities
                (i.e., no more than 10 kg/year). Based on EPA's knowledge of
                manufacturers of those substances, and public input from commenters and
                small entity representatives, EPA believes such manufacturers have less
                information that is known or reasonably ascertainable to them.
                Therefore, the streamlined reporting form reduces the burden of
                reporting on the standard form while still enabling EPA to collect all
                known or reasonably ascertainable historical PFAS data. Additionally,
                EPA considered and is finalizing a longer compliance timeframe for all
                reporting entities. Providing an additional six months for a data
                collection period ahead of the reporting period will reduce the
                opportunity costs on affected firms, particularly small entities,
                without sacrificing any PFAS manufacturing data. In addition, EPA is
                granting small manufacturers (as defined at 40 CFR 704.3) who would
                report exclusively as article importers an additional six months to
                collect data. Therefore, those small entities would have 24 months from
                the effective date of this rule to submit information on their imported
                articles. EPA is finalizing such alternatives to meet the Agency's
                obligations under TSCA sections 8(a)(5)(A) through (C), as this rule is
                requesting information that is neither duplicative nor unnecessary and
                will not exclude manufacturers who are likely to have relevant
                information, while minimizing costs on small manufacturers to the
                extent feasible.
                 Small entity compliance guide. EPA prepared a Small Entity
                Compliance Guide to help small entities comply with the rule. This
                guide is available in the docket for this rulemaking and will be
                available on EPA's website prior to the effective date of this final
                rule (Ref. 14).
                D. Unfunded Mandates Reform Act (UMRA)
                 This action contains a Federal mandate under UMRA, 2 U.S.C. 1531-
                1538, that may result in expenditures of $100 million or more for
                State, local, and Tribal governments, in the aggregate, or for private
                sector in any one year. Accordingly, the EPA has prepared a written
                statement (Ref. 30) as required under UMRA section 202 that is include
                in the docket for this action and is briefly summarized here.
                 1. Authorizing legislation. This rule is issued under the authority
                of TSCA section 8(a)(7) (15 U.S.C. 2607(a)(7)).
                 2. Benefit-cost analysis. EPA has prepared an Economic Analysis
                (Ref. 2) and a Final Regulatory Flexibility Analysis (Ref. 29) to
                evaluate, among other things, the benefits and costs of this rule as
                well as various regulatory options. The rule is calculated to result in
                a total one-time cost to the private sector of approximately $843
                million using a 3 percent discount rate and $800 million using a 7
                percent discount rate. When adjusted for inflation, the $100 million
                UMRA threshold is equivalent to approximately $184 million. Thus, the
                cost of the rule to the private sector in the aggregate exceeds the
                inflation-adjusted UMRA threshold.
                 Because this is an information-collecting rule, EPA is not able to
                quantitatively measure the associated benefits. However, the rule may
                supply information on PFAS to which Federal agencies (and the public)
                do not currently have access. By enhancing the data supplied to risk-
                screening and risk-management programs, EPA expects to more effectively
                and expeditiously evaluate and manage any potential unreasonable risk
                posed by PFAS. The more EPA can base its decisions on actual data
                rather than on assumptions, the better EPA is able to tailor its risk
                management decisions to the level of actual risk, whether higher or
                lower than it would be if based on assumptions alone. Ultimately,
                enhancing the risk evaluation process will have positive consequences
                for human health and the environment and may enable a more efficient
                allocation of EPA's and society's resources. Additionally, this rule
                fulfills EPA's obligations under TSCA section 8(a)(7).
                 3. Impacts on State, local, and Tribal governments. This rule does
                not contain a significant Federal intergovernmental mandate because it
                neither imposes enforceable duties on State, local, or Tribal
                governments nor reduces an authorized amount of Federal financial
                assistance provided to State, local, or Tribal governments. This rule
                contains no regulatory requirements that might significantly or
                uniquely affect small governments. The rule would require reporting
                from certain persons who manufactured (including imported) PFAS for
                commercial purposes, including in articles. Governments do not
                typically engage in these activities, so State, local, and Tribal
                government entities are not expected to be subject to the rule's
                requirements. This action is not subject to the requirements of section
                203 of UMRA because it contains no regulatory requirements that might
                significantly or uniquely affect small governments. The requirements of
                this action would primarily affect manufacturers (including importers)
                of PFAS.
                [[Page 70547]]
                E. Executive Order 13132: Federalism
                 This action does not have federalism implications, as specified in
                Executive Order 13132 (64 FR 43255, August 10, 1999) because it will
                not have substantial direct effects on States, on the relationship
                between the National Government and the States, or on the distribution
                of power and responsibilities among the various levels of government.
                F. Executive Order 13175: Consultation and Coordination With Indian
                Tribal Governments
                 This action does not have Tribal implications, as specified in
                Executive Order 13175 (65 FR 67249, November 9, 2000) because it will
                not have substantial direct effects on Tribal governments, on the
                relationship between the Federal Government and the Indian Tribes, or
                on the distribution of power and responsibilities between the Federal
                Government and Indian Tribes. It does not have substantial direct
                effects on Tribal government because EPA does not anticipate that PFAS
                was manufactured (including imported) for commercial purposes by Tribes
                so this rulemaking is not expected to impose substantial direct
                compliance costs on Tribal governments.
                G. Executive Order 13045: Protection of Children From Environmental
                Health Risks and Safety Risks
                 EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997)
                as applying only to those regulatory actions that concern environmental
                health or safety risks that EPA has reason to believe may
                disproportionately affect children, per the definition of ``covered
                regulatory action'' in section 2-202 of Executive Order 13045. This
                action is not subject to Executive Order 13045, because it does not
                concern an environmental health or safety risk. Since this action does
                not concern human health, EPA's Policy on Children's Health also does
                not apply.
                 Although this action does not concern an environmental health or
                safety risk, this one-time data collection will aid in collecting all
                existing and reasonably ascertainable information related to the
                manufacturing (including importing) of PFAS since 2011. This rule will
                be of use in identifying current data gaps surrounding the knowledge of
                commercially manufactured PFAS. Understanding the extent of existing
                data gaps related to manufactured PFAS will also help inform and tailor
                future EPA actions to address PFAS as needed. This regulatory action
                establishes one-time reporting requirements for PFAS that will result
                in information on the quantity of PFAS to which children may be
                exposed. EPA believes that the information obtained as a result of this
                one-time data collection could also be used by the public, government
                agencies and others to identify potential problems, set priorities, and
                take appropriate steps to reduce any potential human health or
                environmental risks.
                H. Executive Order 13211: Actions Concerning Regulations That
                Significantly Affect Energy Supply, Distribution in Commerce, or Use
                 This action is not a ``significant energy action'' as defined in
                Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not
                likely to have a significant adverse effect on the supply, distribution
                or use of energy. Further, we have concluded that this action is not
                likely to have any adverse effect on the supply, distribution or use of
                energy.
                I. National Technology Transfer and Advancement Act (NTTAA)
                 This rulemaking does not involve technical standards. As such,
                NTTAA section 12(d), 15 U.S.C. 272.
                J. Executive Order 12898: Federal Actions To Address Environmental
                Justice in Minority Populations and Low-Income Populations and
                Executive Order 14096: Revitalizing Our Nation's Commitment to
                Environmental Justice for All
                 The EPA believes that it is not practicable to assess whether the
                human health or environmental conditions that exist prior to this
                action result in disproportionate and adverse effects on communities
                with environmental justice concerns. The purpose of this action is to
                require reporting activity. EPA was unable to perform an environmental
                justice analysis because it lacks data on every exposure source.
                 However, this regulatory action makes changes to the reporting
                requirements for PFAS that will result in more information being
                collected and provided to better evaluate exposures and the risks posed
                by such exposures as explained in Unit II.A., certain PFAS exposure may
                be a hazard to human health. This action establishes one-time reporting
                requirements for companies to submit to EPA certain known or reasonably
                ascertainable information on manufactured PFAS by those entities as
                discussed in detailed in Unit III.D. The determination of potential
                risk to human health and/or the environment depends upon many factors,
                including the toxicity of the chemical, the fate of the chemical in the
                environment, and the amount and duration of human or other exposure to
                the chemical. This action does not directly address human health or
                environmental risks. However, the action will increase the level of
                information available to assess environmental protection for all
                affected populations without having any disproportionate and adverse
                human health or environmental effects on any population, including any
                community with environmental justice concerns. The information obtained
                as a result of this action may be used to collect all existing and
                reasonably ascertainable information related to PFAS-containing
                articles will be of use in identifying current data gaps surrounding
                the knowledge of commercially manufactured PFAS, and reporting of PFAS
                within imported articles will enable EPA to meet its obligations under
                the FY 2020 NDAA. Understanding the extent of existing data gaps
                related to manufactured PFAS will also help inform and tailor future
                EPA actions to address PFAS as needed. EPA also believes that the
                information obtained as a result of this action potentially could be
                used by the public (including communities with environmental justice
                concerns) with access to data which they may use to seek lower
                exposures and consequently reductions in chemical risks for themselves
                and their children. Technical assistance may be provided to communities
                with environmental justice concerns and efforts will be made to ensure
                meaningful access for individuals with limited English proficiency and
                individuals with disabilities. This information can also be used by
                government agencies and others to identify potential problems, set
                priorities, and take appropriate steps to reduce any potential risks to
                human health and the environment. Therefore, informational benefits, of
                the action, including behavioral changes such as consumers avoiding
                specific products, may have positive impact on the human health and
                environmental impacts on all communities, including communities with
                environmental justice concerns.
                K. Congressional Review Act (CRA)
                 This action is subject to the CRA, 5 U.S.C. 801 et seq., and EPA
                will submit a rule report to each House of the Congress and to the
                Comptroller General of the United States. This action is not a ``major
                rule'' as defined by 5 U.S.C. 804(2).

                chapter I, subchapter R, is amended by adding part 705 to read as
                follows:
                PART 705--REPORTING AND RECORDKEEPING REQUIREMENTS FOR CERTAIN PER-
                AND POLYFLUOROALKYL SUBSTANCES
                Sec.

                 Authority: 15 U.S.C. 2607(a)(7).
                Sec. 705.1 Scope, compliance, and enforcement.
                 (a) This part specifies reporting and recordkeeping procedures for
                manufacturers (including importers) of per- and polyfluoroalkyl
                substances (hereafter referred to as PFAS) under section 8(a)(7) of the
                Toxic Substances Control Act (TSCA).
                 (b) TSCA section 15(3) makes it unlawful for any person to fail or
                refuse to submit information required under this part. In addition,
                TSCA section 15(3) makes it unlawful for any person to fail to keep,
                and permit access to, records required by this part. TSCA section 16
                provides that any person who violates a provision of TSCA section 15 is
                liable to the United States for a civil penalty and may be criminally
                prosecuted. Pursuant to TSCA section 17, the Federal Government may
                seek judicial relief to compel submission of TSCA section 8(a)
                information and to otherwise restrain any violation of TSCA section 15.
                TSCA section 11 allows for inspections to assure compliance, and the
                Environmental Protection Agency's (EPA) Administrator may by subpoena
                require the attendance and testimony of witnesses and the production of
                reports, papers, documents, answers to questions, and other information
                that the Administrator deems necessary.
                 (c) Each person who reports under this part must maintain records
                that document information reported under this part and, in accordance
                with TSCA, permit access to, and the copying of, such records by EPA
                officials.
                Sec. 705.3 Definitions.
                 The definitions in this section and the definitions in TSCA section
                3 apply to this part. In addition, the definitions in 40 CFR 704.3 also
                apply to this part, except the definition for small quantities solely
                for research and development.
                 Article means a manufactured item which:
                 (1) Is formed to a specific shape or design during manufacture;
                 (2) Has end use function(s) depending in whole or in part upon its
                shape or design during end use; and
                 (3) Has either no change of chemical composition during its end use
                or only those changes of composition which have no commercial purpose
                separate from that of the article, and that result from a chemical
                reaction that occurs upon end use of other chemical substances,
                mixtures, or articles; except that fluids and particles are not
                considered articles regardless of shape or design.
                 Central Data Exchange or CDX means EPA's centralized electronic
                submission receiving system.
                 Chemical Information Submission System or CISS means EPA's
                electronic, web-based reporting tool for the completion and submission
                of data, reports, and other information, or its successors.
                 Commercial use means the use of a chemical substance or a mixture
                containing a chemical substance (including as part of an article) in a
                commercial enterprise providing saleable goods or services.
                 Consumer use means the use of a chemical substance or a mixture
                containing a chemical substance (including as part of an article) when
                sold to or made available to consumers for their use.
                 Environmental or health effects information means any information
                of any effect of a chemical substance or mixture containing a chemical
                substance on health or the environment or on both. This includes all
                health and safety studies.
                 (1) Not only is information that arises as a result of a formal,
                disciplined study included, but other information relating to the
                effects of a chemical substance or mixture containing a chemical
                substance on health or the environment is also included. Any
                information that bears on the effects of a chemical substance on health
                or the environment would be included.
                 (2) Examples are:
                 (i) Long- and short-term tests of mutagenicity, carcinogenicity, or
                teratogenicity; data on behavioral disorders; dermatoxicity;
                pharmacological effects; mammalian absorption, distribution,
                metabolism, and excretion; cumulative, additive, and synergistic
                effects; and acute, subchronic, and chronic effects.
                 (ii) Tests for ecological or other environmental effects on
                invertebrates, fish, or other animals, and plants, including acute
                toxicity tests, chronic toxicity tests, critical life-stage tests,
                behavioral tests, algal growth tests, seed germination tests, plant
                growth or damage tests, microbial function tests, bioconcentration or
                bioaccumulation tests, and model ecosystem (microcosm) studies.
                 (iii) Assessments of human and environmental exposure, including
                workplace exposure, and impacts of a particular chemical substance or
                mixture containing a chemical substance on the environment, including
                surveys, tests, and studies of: Biological, photochemical, and chemical
                degradation; structure/activity relationships; air, water, and soil
                transport; biomagnification and bioconcentration; and chemical and
                physical properties, e.g., boiling point, vapor pressure, evaporation
                rates from soil and water, octanol/water partition coefficient, and
                water solubility.
                 (iv) Monitoring data, including but not limited to when they have
                been aggregated and analyzed to measure the exposure of humans or the
                environment to a chemical substance or mixture containing a chemical
                substance.
                 Health and safety studies means any study of any effect of a
                chemical substance or mixture on health or the environment or on both,
                including underlying information and epidemiological studies, studies
                of occupational exposure to a chemical substance or mixture,
                toxicological, clinical, and ecological studies of a chemicals
                substance or mixture containing a chemical substance, and any test
                performed under TSCA. The following information is not part of a health
                and safety study:
                 (1) The name, address, or other identifying information for the
                submitting company, including identification of the laboratory that
                conducted the study in cases where the laboratory is part of or closely
                affiliated with the submitting company;
                [[Page 70549]]
                 (2) Internal product codes (i.e., code names for the test substance
                used internally by the submitting company or to identify the test
                substance to the test laboratory);
                 (3) Names and contact details for testing laboratory personnel and
                names and other private information for health and safety study
                participants or persons involved in chemical incidents such as would
                typically be withheld under 5 U.S.C. 552(b)(6) or under other privacy
                laws; and
                 (4) Information pertaining to test substance product development,
                advertising, or marketing plans, or to cost and other financial data.
                 Highest-level U.S. parent company means the highest-level company
                of the site's ownership hierarchy as of the start of the submission
                period during which data are being reported according to the following
                instructions. The highest-level U.S. parent company is located within
                the United States. The following rules govern how to identify the
                highest-level U.S. parent company:
                 (1) If the site is entirely owned by a single U.S. company that is
                not owned by another company, that single company is the U.S. parent
                company.
                 (2) If the site is entirely owned by a single U.S. company that is,
                itself, owned by another U.S.-based company (e.g., it is a division or
                subsidiary of a higher-level company), the highest-level domestic
                company in the ownership hierarchy is the U.S. parent company.
                 (3) If the site is owned by more than one company (e.g., company A
                owns 40 percent, company B owns 35 percent, and company C owns 25
                percent), the company with the largest ownership interest in the site
                is the U.S. parent company. If a higher-level company in the ownership
                hierarchy owns more than one ownership company, then determine the
                entity with the largest ownership by considering the lower-level
                ownerships in combination (e.g., corporation X owns companies B and C,
                for a total ownership of 60 percent for the site).
                 (4) If the site is owned by a 50:50 joint venture or a cooperative,
                the joint venture or cooperative is its own parent company. If the site
                is owned by a U.S. joint venture or cooperative, the highest level of
                the joint venture or cooperative is the U.S. parent company.
                 (5) If the site is federally owned, the highest-level Federal
                agency or department is the U.S. parent company.
                 (6) If the site is owned by a non-Federal public entity, that
                entity (such as a municipality, State, or tribe) is the U.S. parent
                company.
                 Industrial function means the intended physical or chemical
                characteristic for which a chemical substance or mixture is consumed as
                a reactant; incorporated into a formulation, mixture, reaction product
                or article; repackaged; or used.
                 Industrial use means use at a site at which one or more chemical
                substances or mixtures are manufactured (including imported) or
                processed.
                 Intended for use by children means the chemical substance or
                mixture is used in or on a product that is specifically intended for
                use by children aged 14 or younger. A chemical substance or mixture
                containing a chemical substance is intended for use by children when
                the submitter answers ``yes'' to at least one of the following
                questions for the product into which the submitter's chemical substance
                or mixture containing a chemical substance is incorporated:
                 (1) Is the product commonly recognized (i.e., by a reasonable
                person) as being intended for children aged 14 or younger?
                 (2) Does the manufacturer of the product state through product
                labeling or other written materials that the product is intended for or
                will be used by children aged 14 or younger?
                 (3) Is the advertising, promotion, or marketing of the product
                aimed at children aged 14 or younger?
                 Known to or reasonably ascertainable by means all information in a
                person's possession or control, plus all information that a reasonable
                person similarly situated might be expected to possess, control, or
                know.
                 Manufacture means to import into the customs territory of the
                United States (as defined in general note 2 of the Harmonized Tariff
                Schedule of the United States (19 U.S.C. 1202)), produce, or
                manufacture for commercial purposes.
                 Manufacture for commercial purposes means:
                 (1) To import, produce, or manufacture with the purpose of
                obtaining an immediate or eventual commercial advantage for the
                manufacturer, and includes among other things, such ``manufacture'' of
                any amount of a chemical substance or mixture containing a chemical
                substance:
                 (i) For commercial distribution, including for test marketing; and/
                or
                 (ii) For use by the manufacturer, including use for product
                research and development, or as an intermediate.
                 (2) Manufacture for commercial purposes also applies to substances
                that are produced coincidentally during the manufacture, processing,
                use, or disposal of another substance or mixture containing a chemical
                substance, including both byproducts that are separated from that other
                substance or mixture containing a chemical substance and impurities
                that remain in that substance or mixture containing a chemical
                substance. Such byproducts and impurities may, or may not, in
                themselves have commercial value. They are nonetheless produced for the
                purpose of obtaining a commercial advantage since they are part of the
                manufacture of a chemical product for a commercial purpose.
                 Per- and polyfluoroalkyl substances or PFAS means, for the purpose
                of this part, any chemical substance or mixture containing a chemical
                substance that structurally contains at least one of the following
                three sub-structures:
                 (1) R-(CF2)-CF(R')R'', where both the CF2 and
                CF moieties are saturated carbons.
                 (2) R-CF2OCF2-R', where R and R' can either
                be F, O, or saturated carbons.
                 (3) CF3C(CF3)R'R'', where R' and R'' can
                either be F or saturated carbons.
                 Possession or control means in possession or control of the
                submitter, or of any subsidiary, partnership in which the submitter is
                a general partner, parent company, or any company or partnership which
                the parent company owns or controls, if the subsidiary, parent company,
                or other company or partnership is associated with the submitter in the
                research, development, test marketing, or commercial marketing of the
                chemical substance in question. (A parent company owns or controls
                another company if the parent owns or controls 50 percent or more of
                the other company's voting stock. A parent company owns or controls any
                partnership in which it is a general partner.) Information is included
                within this definition if it is:
                 (1) In files maintained by submitter's employees who are:
                 (i) Associated with research, development, test marketing, or
                commercial marketing of the chemical substance in question; and/or
                 (ii) Reasonably likely to have such data.
                 (2) Maintained in the files of other agents of the submitter who
                are associated with research, development, test marketing, or
                commercial marketing of the chemical substance in question in the
                course of their employment as such agents.
                 Research and development (R&D) means activities intended solely as
                scientific experimentation, research, or analysis. R&D focuses on the
                analysis of the chemical or physical characteristics, the performance,
                or the production characteristics of a chemical substance, a mixture
                containing the substance, or
                [[Page 70550]]
                an article. R&D encompasses a wide range of activities which may occur
                in a laboratory, pilot plant, commercial plant outside the research
                facility, or at other sites appropriate for R&D. General distribution
                of chemical substances to consumers does not constitute R&D.
                 Site-limited means a chemical substance is manufactured and
                processed only within a site and is not distributed as a chemical
                substance or as part of a mixture or article containing a chemical
                substance outside the site. Imported chemical substances are never
                site-limited.
                 Worker means someone at a site of manufacture, import, or
                processing who performs work activities near sources of a chemical
                substance or mixture or directly handles the chemical substance or
                mixture during the performance of work activities.
                Sec. 705.5 Substances for which reports must be submitted.
                 The requirements of this part apply to all chemical substances and
                mixtures containing a chemical substance (including articles) that are
                a PFAS, consistent with the definition of PFAS at Sec. 705.3.
                Sec. 705.10 Persons who must report.
                 Persons who have manufactured for commercial purposes a chemical
                substance identified in Sec. 705.5 at any period from January 1, 2011,
                through the end of the last calendar year prior to November 13, 2023,
                except as described in Sec. 705.12, is subject to the requirements of
                this part.
                Sec. 705.12 Activities for which reporting is not required.
                 Reporting under this part is not required for the import of
                municipal solid waste streams for the purpose of disposal or
                destruction of the waste. Additionally, reporting is not required for a
                Federal agency which imports PFAS when it is not for any immediate or
                eventual commercial advantage.
                Sec. 705.15 What information to report.
                 For the one-time submission, persons identified in Sec. 705.10
                must report to EPA, for each site of each of the chemical substances
                identified in Sec. 705.5, the following information to the extent
                known to or reasonably ascertainable by them, except as allowed under
                Sec. 705.18. In the event that actual data is not known to or
                reasonably ascertainable by the submitter, then reasonable estimates
                may be submitted:
                 (a) Company and plant site information. The following currently
                correct company and plant site information must be reported for each
                site at which a reportable chemical substance is manufactured (see 40
                CFR 711.3 for the ``site'' for importers):
                 (1) The highest-level U.S. parent company name, address, and Dun
                and Bradstreet D-U-N-S[supreg] (D&B) number, if one exists.
                 (2) The name of a person who will serve as Authorized Official for
                the submitter company, and who will be able to sign the certification
                statement as described in Sec. 705.30(d), the Authorized Official's
                full mailing address, telephone number, and email address.
                 (3) The name of a person who will serve as technical contact for
                the submitter company, and who will be able to answer questions about
                the information submitted by the company to EPA, the contact person's
                full mailing address, telephone number, and email address.
                 (4) The name, full street address, and six-digit North American
                Industry Classification System (NAICS) code(s) of the site. A submitter
                under this part must include the appropriate D&B number for each plant
                site reported, and the county or parish (or other jurisdictional
                indicator) in which the plant site is located. A submitter under this
                part must obtain a D&B number for the site reported if none exists. A
                submitter under this part must also provide other site identification
                numbers, including the Facility Registry Service (FRS) identification
                number, if they exist.
                 (b) Chemical-specific information. The following chemical-specific
                information must be reported for each chemical substance that is a PFAS
                manufactured for each year since January 1, 2011, except as allowed
                under Sec. 705.18. This includes each chemical substance that is a
                PFAS and incorporated into mixtures:
                 (1) The common or trade name, the chemical identity, and, except
                for chemical substances that are Class 1 substances on the TSCA
                Inventory, the representative molecular structure of each PFAS for
                which such a report is required.
                 (i) The specific, currently correct Chemical Abstracts (CA) Index
                name as used to list the chemical substance on the TSCA Inventory and
                the correct corresponding Chemical Abstracts Service Registry Number
                (CASRN) for each reportable PFAS at each site. Submitters who wish to
                report chemical substances listed on the confidential portion of the
                TSCA Inventory will need to report the chemical substance using a TSCA
                Accession Number. If a submitter has a low-volume exemption (LVE) case
                number for the chemical substance, that number may also be used if a
                CASRN is not known to or reasonably ascertainable by the submitter.
                 (ii) In addition to reporting the number itself, submitters must
                specify the type of number they are reporting by selecting from among
                the codes in table 1 to this paragraph (b)(1)(ii).
                 Table 1 to Paragraph (b)(1)(ii)--Codes To Specify Type of Chemical
                 Identifying Number
                ------------------------------------------------------------------------
                 Code Number type
                ------------------------------------------------------------------------
                A............................... TSCA Accession Number.
                C............................... Chemical Abstracts Service Registry
                 Number (CASRN).
                L............................... Low-volume exemption (LVE) case
                 number.
                ------------------------------------------------------------------------
                 (iii) If the CASRN or specific identifier (i.e., Accession Number
                or LVE number) of the PFAS is not known to or reasonably ascertainable
                (NKRA) to the submitter (e.g., if the chemical identity is claimed as
                confidential business information by the submitter's supplier, or if
                the submitter knows they have a PFAS but are unable to ascertain its
                specific identifier and/or specific chemical identity), the submitter
                may provide a generic name or description of the PFAS and also initiate
                a joint submission if the secondary submitter is known. The submitter
                may only initiate a joint submission if the CASRN or the specific
                identifier (i.e., Accession Number or LVE number) is not known or
                reasonably ascertainable, and a secondary submitter (who would provide
                such information) is known. The manufacturer (including importer) must
                use the reporting tool described under Sec. 705.35 to ask the supplier
                or other entity to provide the chemical identity directly to EPA in a
                joint submission. Such request must include instructions for submitting
                chemical identity information electronically, using e-CDRweb and CDX
                (see 40 CFR 711.35), and for clearly referencing the manufacturer's
                (including importer) submission. Contact information for the supplier
                or other entity, a trade name or other designation for the chemical
                substance, and a copy of the request to the supplier or other entity
                must be included with the manufacturer's (including importer)
                submission. If, after conducting due diligence and reviewing known or
                reasonably ascertainable information, a secondary submitter to complete
                the joint submission is not known, the reporter may indicate that the
                secondary submitter is NKRA. However, the PFAS manufacturer would be
                required to
                [[Page 70551]]
                provide as much identifying detail as they have regarding the PFAS
                identity, and would be able to report to EPA without initiating a joint
                submission even if they do not know the underlying identity of the
                chemical substance.
                 (2) The physical form(s) of the PFAS as it is sent off-site from
                each site. If the PFAS is site-limited, you must report the physical
                form(s) of the PFAS at the time it is reacted on-site to produce a

                processing or use operation, sector, and function category as reported
                in paragraph (c) of this section. Where a particular combination of
                industrial processing or use operation, sector, and function category
                accounts for less than
                [[Page 70554]]
                5 percent of the submitter's site's total production volume of a
                reportable chemical substance, the percentage must not be rounded off
                to 0 percent. Instead, in such a case, submitters must report the
                percentage, rounded off to the closest 1 percent, of the submitter's
                site's total production volume of the reportable chemical substance
                associated with the particular combination of industrial processing or
                use operation, sector, and function category.

                than 5 percent of the total production volume of a reportable chemical
                substance, the percentage must not be rounded off to 0 percent.
                Instead, in such a case, submitters must report the percentage, rounded
                off to the closest 1 percent, of the submitter's site's total
                production volume of the reportable chemical substance associated with
                the particular consumer and commercial product category.

                from the manufacture, processing, use, or disposal of each PFAS.
                 (1) Byproduct identification. For each byproduct produced from the
                manufacture, processing, use, or disposal of a PFAS, the submitter will
                identify the byproduct by its specific, currently correct CA Index name
                as used to list the chemical substance on the TSCA Inventory and the
                correct corresponding CASRN. A submitter under this part may use a
                known EPA-designated TSCA Accession Number for a chemical substance in
                lieu of a CASRN when a CASRN is not known to or reasonably
                ascertainable by the submitter. Submitters who wish to report chemical
                substances listed on the confidential portion of the TSCA Inventory
                will need to report the chemical substance using a TSCA Accession
                Number.
                 (i) In addition to reporting the number itself, submitters must
                specify the type of number they are reporting by selecting from among

                manufacture, process, use, or disposal) manufactured the byproduct.
                 (2) Releases. An indication of whether the byproduct is released to
                the environment, and if so, the environmental medium to which it is
                released (i.e., air, water, land).
                 (3) Volume. For each year, the byproduct volume (in pounds)
                released to the environment.
                 (f) Environmental and health effects. All existing information
                concerning the environmental and health effects of such substance or
                mixture containing a chemical substance in the manufacturer's

                 workers.
                W7.............................. At least 1,000 but fewer than 10,000
                 workers.
                W8.............................. At least 10,000 workers.
                ------------------------------------------------------------------------
                 (3) Exposure scenarios. For each worker activity in this paragraph
                (g), the maximum duration of exposure for any worker at the
                manufacturing site, for each of the following scenarios:
                 (i) The daily exposure duration (in hours per day) in the case of
                the worker with greatest annual exposure frequency (i.e., the worker
                exposed the most days per year); and
                 (ii) The annual exposure frequency (in days per year) in the case
                of the worker with greatest daily exposure duration (i.e., the worker
                exposed for the most hours per day during the year).
                 (4) Exposure by category. For each combination of industrial
                processing or use operation, sector, and function category identified
                in paragraph (c) of this section, the submitter must estimate the
                number of workers reasonably likely to be exposed to each PFAS. For
                each combination associated with each chemical substance, the submitter
                must select from among the worker ranges listed in table 7 to paragraph
                (g)(2) of this section and report the corresponding code (i.e., W1
                though W8).
                 (5) Duration of exposure industrial use. For each PFAS, the maximum
                duration of exposure for any worker for each combination of industrial
                processing or use operation, sector, and function category, for each of
                the following scenarios:
                 (i) The daily exposure duration (in hours per day) in the case of
                the worker with the greatest annual exposure frequency (i.e., the
                worker exposed the most days per year); and
                 (ii) The annual exposure frequency (in days per year) in the case
                of the worker with the greatest daily exposure duration (i.e., the
                worker exposed for the most hours per day during the year).
                 (6) Commercial workers. Where the PFAS is used in a commercial
                product,
                [[Page 70555]]
                the submitter must estimate the number of commercial workers reasonably
                likely to be exposed to each reportable chemical substance. For each
                commercial use associated with each substance, the submitter must
                select from among the worker ranges listed in table 7 to paragraph
                (g)(2) of this section and report the corresponding code (i.e., W1
                though W8).
                 (7) Duration of exposure commercial use. For each PFAS, the maximum
                duration of exposure for any worker for each commercial use, for each
                of the following scenarios:
                 (i) The daily exposure duration (in hours per day) in the case of
                the worker with greatest annual exposure frequency (i.e., the worker
                exposed the most days per year); and
                 (ii) The annual exposure frequency (in days per year) in the case
                of the worker with greatest daily exposure duration (i.e., the worker
                exposed for the most hours per day during the year).
                 (h) Disposal data. During the years in which the PFAS was
                manufactured, the manners or methods of its disposal, and any changes
                to the disposal methods or processes.
                 (1) Categories of disposal methods. Description of disposal
                processes or methods, using the appropriate codes in table 8 to this
                paragraph (h)(1), and additional descriptions as needed.

                Sec. 705.18 Article importer and R&D substance reporting options.
                 For the one-time submission, certain manufacturers have the option
                to use a streamlined reporting form if they do not know nor can
                reasonably ascertain information requested under Sec. 705.15, beyond
                what is listed in this part. Paragraph (a) of this section lists the
                information which a manufacturer who has imported a PFAS within an
                article must report to the extent they know or can reasonably
                ascertain. Paragraph (b) of this section lists the information that
                manufacturers of PFAS that are solely R&D substances manufactured in
                volumes no greater than 10 kilograms per year must report to the extent
                they know or can reasonably ascertain.
                 (a) Article reporting. Any importer of an article which contains a
                chemical substance that is a PFAS and who meets the reporting
                requirements described in Sec. 705.10 has the option to submit
                information to EPA using a streamlined reporting form for that PFAS in
                the imported article, for each year since January 1, 2011, in which the
                PFAS was imported in an article. Information must be submitted to the
                extent the submitter knows or can reasonably ascertain. In the event
                that actual data is not known to or reasonably ascertainable by the
                submitter, then reasonable estimates may be submitted. The information
                requested on the streamlined reporting form for article importers
                includes:
                 (1) Company and plant site information. All company and plant site
                information requested under Sec. 705.15(a) shall be reported.
                 (2) Chemical-specific information. The following chemical-specific
                information must be reported for each chemical substance that is a PFAS
                imported in an article, for each year since January 1, 2011, in which
                that PFAS was imported within an article.
                 (i) The common or trade name, the chemical identity, and, except
                for chemical substances that are Class 1 substances on the TSCA
                Inventory (Inventory), the representative molecular structure of each
                PFAS for which such a report is required. Submitters who wish to report
                chemical substances listed on the confidential portion of the Inventory
                will need to report the chemical substance using a TSCA Accession
                Number. If a submitter has a low-volume exemption (LVE) case number for
                the chemical substance, that number may also be used if a CASRN is not
                known to or reasonably ascertainable by the submitter. In addition to
                reporting the number itself, submitters must specify the type of number
                they are reporting by selecting from among the codes in table 1 to
                Sec. 705.15(b)(1)(ii).
                 (ii) If the specific chemical identity of the PFAS imported in an
                article is not known to or reasonably ascertainable to the submitter
                (e.g., if the chemical identity is claimed as confidential business
                information by the submitter's supplier, or if the submitter knows they
                have a PFAS but is unable to ascertain its specific chemical identity),
                the submitter may provide a generic name or description of the PFAS.
                 (3) Categories of use. For each year since January 1, 2011, report
                the following information on categories of use of each PFAS imported in
                an article.
                 (i) Industrial processing and use information. A designation
                indicating the type of industrial processing or use operation(s) at
                each site that receives a PFAS from the submitter site directly or
                indirectly (whether the recipient site(s) are controlled by the
                submitter site or not). For each PFAS that was imported in an article,
                report the letters which correspond to the appropriate processing or
                use operation(s) listed in table 2 to Sec. 705.15(c)(1). A particular
                designation may need to be reported more than once, to the extent that
                a submitter reports more than one sector that applies to a given
                designation under this paragraph (a)(3)(i).
                 (ii) Industrial activities sector. A code indicating the sector(s)
                that best describe the industrial activities associated with each
                industrial processing or use operation reported under this section. For
                each PFAS that was imported in an article, report the code that
                corresponds to the appropriate sector(s) listed in table 3 to Sec.
                705.15(c)(2). A particular sector code may need to be reported more
                than once, to the extent that a submitter reports more than one
                function code that applies to a given sector code under this paragraph
                (a)(3)(ii).
                 (iii) Sector specific function categories. For each sector reported
                under paragraph (a)(3)(ii) of this section, the applicable code(s) from
                table 4 to Sec. 705.15(c)(3) must be selected to designate the
                function category(ies) that best represents the specific manner in
                which the PFAS in the imported article is used.
                [[Page 70556]]
                 (iv) Consumer and commercial use information. Using the applicable
                codes listed in table 5 to Sec. 705.15(c)(4), submitters must
                designate the consumer and commercial product category(ies) that best
                describe the consumer and commercial products in which each PFAS that
                is in an imported article is used (whether the recipient site(s) are
                controlled by the submitter site or not). If more than 10 codes apply
                to a PFAS in an imported article, submitters need only report the 10
                codes for PFAS that cumulatively represent the largest percentage of
                the submitter's production volume for that chemical, measured by
                weight. If none of the listed consumer and commercial product
                categories accurately describe the consumer and commercial products in
                which each PFAS is used, the category ``Other'' may be used, and must
                include a description of the use.
                 (v) Product specific function categories. For each consumer and
                commercial product category reported under paragraph (a)(3)(iv) of this
                section, the applicable code(s) described in table 4 to Sec.
                705.15(c)(3) must be selected to designate the function category(ies)
                that best represents the specific manner in which the PFAS in an
                imported article is used.
                 (vi) Consumer or commercial use designation. Submitters must
                indicate, for each consumer and commercial product category reported
                under paragraph (a)(3)(v) of this section, whether the use is a
                consumer or a commercial use, or both.
                 (vii) In or on consumer products intended for children. Submitters
                must determine, within each consumer and commercial product category
                reported under paragraph (a)(3)(v) of this section, whether any amount
                of each reportable chemical substance manufactured (including imported)
                by the submitter is present in (for example, a plasticizer chemical
                substance used to make pacifiers) or on (for example, as a component in
                the paint on a toy) any consumer products intended for use by children
                age 14 or younger, regardless of the concentration of the chemical
                substance remaining in or on the product. Submitters must select from
                the following options: The chemical substance is used in or on any
                consumer products intended for use by children; the chemical substance
                is not used in or on any consumer products intended for use by
                children; or information as to whether the chemical substance is used
                in or on any consumer products intended for use by children is not
                known to or reasonably ascertainable by the submitter.
                 (viii) Estimated maximum concentration. For each year where the
                PFAS in an imported article is used in consumer or commercial products,
                the submitter must report the estimated typical maximum concentration,
                measured by weight, of the chemical substance in each consumer and
                commercial product category reported under paragraph (a)(3)(v) of this
                section. For each PFAS in an imported article in each commercial and
                consumer product category reported under paragraph (a)(3)(v) of this
                section, submitters must select from among the ranges of concentrations
                listed in table 1 to this paragraph (a)(3)(viii) and report the
                corresponding code (i.e., AM1 through AM5):

                ------------------------------------------------------------------------
                 (5) Additional article data. The submitter has the option to
                provide any additional information to EPA that is requested under Sec.
                705.15 on the PFAS imported in an article, including supplemental
                attachments.
                 (b) Research and development (R&D). Any manufacturer of a PFAS R&D
                substance that was manufactured in volumes no greater than 10 kilograms
                per year and who meets the reporting requirements described in Sec.
                705.10 has the option to submit information to EPA using a streamlined
                reporting form for each such PFAS, for each year since January 1, 2011,
                in which the PFAS was manufactured for R&D purposes in volumes no
                greater than 10 kilograms per year. Information must be submitted to
                the extent the submitter knows or can reasonably ascertain. In the
                event that actual data is not known to or reasonably ascertainable by
                the submitter, then reasonable estimates may be submitted. The
                information requested on the streamlined reporting form for R&D
                manufacturers includes:
                 (1) Company and plant site information. All company and plant site
                information requested under Sec. 705.15(a) shall be reported.
                 (2) Chemical-specific information. The following chemical-specific
                information must be reported for each R&D chemical substance that is a
                PFAS and each mixture containing a chemical substance that is a PFAS
                and meets the requirements for the reporting option under this
                paragraph (b)(2). The information must be reported for each year since
                January 1, 2011, in which that PFAS was manufactured for R&D purposes
                in quantities no greater than 10 kilograms per year.
                 (i) The common or trade name, the chemical identity, and, except
                for chemical substances that are Class 1 substances on the TSCA
                Inventory, the representative molecular structure of each PFAS for
                which such a report is required. Submitters who wish to report chemical
                substances listed on the confidential portion of the TSCA Inventory
                will need to report the chemical substance using a TSCA Accession
                Number. If a submitter has a low-volume exemption (LVE) case number for
                the chemical substance, that number may also be used if a CASRN is not
                known to or reasonably ascertainable by the submitter. In addition to
                reporting the number itself, submitters must specify the type of number
                they are reporting by selecting from among the codes in table 1 to
                Sec. 705.15(b)(1)(ii).
                 (ii) If the specific chemical identity of the PFAS is not known to
                or reasonably ascertainable to the submitter (e.g., if the chemical
                identity is claimed as confidential business information by the
                submitter's supplier, or if the submitter knows they have a PFAS but
                are unable
                [[Page 70557]]
                to ascertain its specific chemical identity), the submitter may provide
                a generic name or description of the PFAS.
                 (3) Production volume. The submitter must report for each year
                since January 1, 2011, in which the PFAS was manufactured, the total
                annual volume (in pounds) of each PFAS domestically manufactured or
                imported at each site. The total annual domestically manufactured
                volume (not including imported volume) and the total annual imported
                volume must be separately reported. These amounts must be reported to
                two significant figures of accuracy.
                 (i) A designation indicating, for each PFAS at each site, whether
                any imported PFAS is ever physically present at the reporting site.
                 (ii) [Reserved]
                 (4) Additional R&D data. The submitter has the option to provide
                any additional information to EPA that is requested under Sec. 705.15
                on the PFAS, including supplemental attachments.
                Sec. 705.20 When to report.
                 All information reported to EPA in response to the requirements of
                this part must be submitted during the applicable submission period.
                For all reporters submitting information pursuant to Sec. Sec. 705.15
                and 705.18(b) (research and development), the submission period shall
                begin one year following November 13, 2023, and last for six months:
                November 12, 2024, through May 8, 2025. For any reporter who is
                reporting under this part exclusively pursuant to Sec. 705.18(a)
                (article importers), and is also considered a small manufacturer under
                the definition at 40 CFR 704.3, the submission period shall begin one
                year following November 13, 2023, and last for 12 months: November 12,
                2024, through November 10, 2025.
                Sec. 705.22 Duplicative reporting.
                 Any person covered in this part may notify EPA through the
                electronic reporting system in Sec. 705.35 that certain information
                has already been submitted to EPA, and any such person does not need to
                re-submit the information. The notification must include the statutory
                and regulatory provision under which the information was submitted and
                in which year it was submitted. This ability is limited to the type of
                information listed in this section. If the previous submission did not
                account for all information required to be submitted pursuant to this
                part (e.g., due to exemptions inapplicable to this part), then the
                person may not rely on that prior submission to satisfy the reporting
                requirements of this part.
                 (a) Chemical Data Reporting rule. If a person identified in Sec.
                705.10 has already reported certain information in Sec. 705.15 to EPA
                pursuant to the Chemical Data Reporting rule at 40 CFR part 711, then
                duplicative reporting of that information is not required of the years
                for which the information has already been reported. Such information
                that may potentially be duplicative under this part is limited to:
                 (1) Chemical description. Physical state of the chemical or mixture
                containing a chemical substance, pursuant to 40 CFR

                711.15(b)(3)(iii) through (v).
                 (b) Greenhouse Gas Reporting rule. If a person identified in Sec.
                705.10 has already reported certain information in Sec. 705.15 to EPA
                pursuant to the Greenhouse Gas Reporting rule at 40 CFR part 98, then
                duplicative reporting of that information is not required of the years
                for which the information has already been reported. Such information
                that may potentially be duplicative under this part is limited to:
                 (1) Imported. Production volume (imported), pursuant to 40 CFR

                CFR part 98.
                 (c) Toxics Release Inventory reporting rule. If a person identified
                in Sec. 705.10 has already reported certain information in Sec.
                705.15 to EPA pursuant to the Toxics Release Inventory reporting rule
                at 40 CFR part 372, then duplicative reporting of that information is
                not required of the years for which the information has already been
                reported. Such information that may potentially be duplicative under
                this part is limited to:
                 (1) Recycled. Total volume recycled on-site, pursuant to 40 CFR
                372.85(b)(16).
                 (2) Disposal. Description of disposal process(es), pursuant to 40

                CFR 372.85(b)(16).
                 (d) TSCA sections 8(d) and 8(e) reporting. If a person identified
                in Sec. 705.10 has already reported certain information in Sec.
                705.15(f) to EPA, then duplicative reporting of that information is not
                required of the years for which the information has already been
                reported. Such information that may potentially be duplicative under
                this part is limited to health and safety studies submitted pursuant to
                TSCA section 8(d), notification of substantial risks pursuant to TSCA
                section 8(e), or other information concerning environmental and health
                effects of the PFAS.
                 (e) Byproduct reporting. If a person identified in Sec. 705.10
                must report byproducts information pursuant to Sec. 705.15(e), and
                those byproducts are also PFAS that are reported independently pursuant
                to this part, then duplicative reporting of the environmental releases
                as byproducts is not required. Such information that may potentially be
                duplicative is limited to:
                 (1) Incineration. An indication of whether the byproduct is
                released to the environment, and if so, the environmental medium to
                which it is released (i.e., air, water, land), pursuant to Sec.
                705.15(e)(2).
                 (2) Byproduct volume. For each year, the byproduct volume (in
                pounds) released to the environment, pursuant to Sec. 705.15(e)(3).
                 (f) Environmental and health effects information. If a person
                identified in Sec. 705.10 has already reported the
                [[Page 70558]]
                information in Sec. 705.15(f) to EPA, then duplicative reporting of
                that information is not required, except to the extent required by to
                Sec. 705.30. The notification required by this paragraph (f) must also
                include the EPA office (e.g., EPA region or Headquarters Office) and
                case number or other identifier for the prior submission.
                 (g) Reporting timeframe. Any person covered in this part must
                report all information to EPA in Sec. 705.15 for each year since
                January 1, 2011, in which that person manufactured a chemical substance
                that is a PFAS or a mixture containing a PFAS. If a person has already
                reported any of the data elements identified in paragraph (a) of this
                section, but not for all years since 2011, then that person must submit
                the required information for the intervening years. If a person has
                already reported any of the data elements identified in paragraph (a),
                (b), or (c) of this section, and the previous submissions did not
                account for all activities that are reportable under this part due to
                exemptions or thresholds that do not apply to this part, then that
                information is not considered duplicative reporting, and the person
                must submit information for that data element responsive to this part.
                Sec. 705.25 Recordkeeping requirements.
                 Each person who is subject to the reporting requirements of this
                part must retain records that document any information reported to EPA.
                Relevant records must be retained for a period of 5 years beginning on
                the last day of the submission period.
                Sec. 705.30 Confidentiality claims.
                 (a) Making confidentiality claims--(1) Generally. Any person
                submitting information under this part may assert a confidentiality
                claim for that information, except for information described in
                paragraph (a)(2) of this section. All such confidentiality claims must
                be asserted at the time the information is submitted. Instructions for
                asserting confidentiality claims are provided in the document
                identified in Sec. 705.35. Information claimed as confidential
                business information in accordance with this section will be treated
                and disclosed in accordance with the procedures in 40 CFR part 703 and
                TSCA section 14.
                 (2) Exceptions. Confidentiality claims cannot be asserted for the
                following:
                 (i) Specific chemical identity if the chemical is on the public
                (non-confidential) TSCA Inventory or reported as non-confidential in an
                LVE;
                 (ii) For processing and use data elements required by Sec. Sec.
                705.15(c)(1) through (7) and 705.18(a)(3)(i) through (vii);
                 (iii) When a response is left blank or designated as ``not known or
                reasonably ascertainable;''
                 (iv) For specific chemical identity by submitters of article
                importer forms described in Sec. 705.18(a);
                 (v) For all generic chemical names;
                 (vi) For any PFAS that are on the public (non-confidential) TSCA
                Inventory, the chemical's CASRN;
                 (vii) For the Inventory Accession Numbers for PFAS that are on the
                confidential TSCA Inventory; or,
                 (viii) For LVE numbers.
                 (3) All existing information concerning environmental and health
                effects. (i) Any person submitting a health and safety study, or
                information from a healthy and safety study, under this part may only
                assert a confidentiality claim for information that discloses processes
                used in the manufacturing or processing of a chemical substance or
                mixture or, in the case of a mixture, the release of data disclosing
                the portion of the mixture comprised by any of the chemical substances
                in the mixture.
                 (ii) If any information submitted under Sec. 705.15(f) is claimed
                as confidential business information, a person who submits the
                information must provide EPA, at the time of submission, a sanitized
                copy for public release, removing only that information that is claimed
                as confidential business information.
                 (iii) Any person who has previously submitted information under
                Sec. 705.15(f) and claimed it as confidential business information is
                required to reassert and re-substantiate the confidential business
                information claim if they seek to maintain the claim of confidential
                business information. Such persons are required to submit s a revised
                sanitized copy.
                 (b) Substantiation of confidentiality claims. (1) Unless exempted,
                all confidentiality claims require substantiation at the time of
                submission and must be signed and dated by an authorized official.
                 (2) Confidentiality claims for the following data elements are
                exempt from the substantiation requirement in paragraph (b)(1) of this
                section:
                 (i) Volume. Production volume information required pursuant to
                Sec. Sec. 705.15(d)(1), (5), and (6) and 705.18(a)(4) and (b)(3)(i).
                 (ii) Primary submitter. Joint submission information from the
                primary submitter, consisting of trade name and supplier identification
                required pursuant to Sec. 705.15(b)(1)(i) and (ii).
                 (iii) Secondary submitter. Joint submission information from the
                secondary submitter, consisting of the percentage of formulation
                required pursuant to Sec. 705.15(b)(1)(i) and (ii).
                 (c) Marking information claimed as confidential business
                information in confidentiality substantiation documentation. If any of
                the information contained in the answers to the questions listed in
                paragraph (e) of this section is asserted to contain information that
                itself is considered to be confidential, you must clearly identify the
                information that is claimed confidential.
                 (d) Certification statement for claims. An authorized official
                representing a person asserting a claim of confidentiality must certify
                that the submission complies with the requirements of this part by
                signing and dating the following certification statement:
                 ``I certify that all claims for confidentiality asserted with
                this submission are true and correct, and all information submitted
                herein to substantiate such claims is true and correct. Any knowing
                and willful misrepresentation is subject to criminal penalty
                pursuant to 18 U.S.C. 1001. I further certify that: (1) I have taken
                reasonable measures to protect the confidentiality of the
                information; (2) I have determined that the information is not
                required to be disclosed or otherwise made available to the public
                under any other Federal law; (3) I have a reasonable basis to
                conclude that disclosure of the information is likely to cause
                substantial harm to the competitive position of my company; and (4)
                I have a reasonable basis to believe that the information is not
                readily discoverable through reverse engineering.''
                 (e) Substantiation requirements for all types of confidentiality
                claims. For each data element that is claimed as confidential business
                information, you must submit with your report detailed written answers
                to the following questions:
                 (1) Substantial harm due to release. Please specifically explain
                what harm to the competitive position of your business would be likely
                to result from the release of the information claimed as confidential
                business information. How would that harm be substantial? Why is the
                substantial harm to your competitive position likely (i.e., probable)
                to be caused by release of the information rather than just possible?
                If you claimed multiple types of information to be confidential (e.g.,
                site information, exposure information, environmental release
                information, etc.), explain how disclosure of each type of information
                would be likely to cause substantial harm to the competitive position
                of your business. (40 CFR 703.5(b)(3))
                [[Page 70559]]
                 (2) Precautions to protect confidentiality. Has your business taken
                precautions to protect the confidentiality of the disclosed
                information? If yes, please explain and identify the specific measures,
                including but not limited to internal controls, that your business has
                taken to protect the information claimed as confidential business
                information. If the same or similar information was previously reported
                to EPA as non-confidential (such as in an earlier version of this
                submission), please explain the circumstances of that prior submission
                and reasons for believing the information is nonetheless still
                confidential.
                 (3) Disclosure under Federal law or publicly available information.
                (i) Is any of the information claimed as confidential business
                information required to be publicly disclosed under any other Federal
                law? If yes, please explain.
                 (ii) Does any of the information claimed as confidential business
                information otherwise appear in any public documents, including (but
                not limited to) safety data sheets; advertising or promotional
                material; professional or trade publications; state, local, or Federal
                agency files; or any other media or publications available to the
                general public? If yes, please explain why the information should be
                treated as confidential. If this chemical is patented and the patent
                reveals the information you are claiming to be confidential business
                information, please explain your reasons for believing the information
                is nonetheless still confidential.
                 (4) Duration of claims. Is the claim of confidentiality intended to
                last less than 10 years (see TSCA section 14(e)(1)(B))? If yes, please
                indicate the number of years (between 1-10 years) or the specific date
                after which the claim is withdrawn.
                 (5) Previously disclosed information. Has EPA, another Federal
                agency, or court made any confidentiality determination regarding
                information associated with this chemical substance? If yes, please
                provide the circumstances associated with the prior determination,
                whether the information was found to be entitled to confidential
                treatment, the entity that made the decision, and the date of the
                determination.
                 (f) Additional requirements for specific chemical identity. A
                person may assert a claim of confidentiality for the specific chemical
                identity of a chemical substance as described in Sec. Sec.
                705.15(b)(1)(i) and 705.18(b)(2)(i) only if the identity of that
                chemical substance is treated as confidential in the Master Inventory
                File (or as a confidential LVE) as of the time the report is submitted
                for that chemical substance, if that substance is currently on the
                Inventory or is an LVE. Any person who asserts a claim of
                confidentiality for the specific chemical identity under this paragraph
                must provide a generic chemical name. To assert a claim of
                confidentiality for the identity of a reportable chemical substance,
                you must submit with the report detailed written answers to the
                questions from paragraph (b) of this section and to the following
                questions.
                 (1) Chemical substance in U.S. commerce. Is this chemical substance
                publicly known (including by your competitors) to be in U.S. commerce?
                If yes, please explain why the specific chemical identity should still
                be afforded confidential status (e.g., the chemical substance is
                publicly known only as being distributed in commerce for research and
                development purposes, but no other information about the current
                commercial distribution of the chemical substance in the United States
                is publicly available) (40 CFR 703.5(b)(4)). If no, please complete the
                certification statement:
                 ``I certify that on the date referenced, I searched the internet
                for the chemical substance identity (i.e., by both chemical
                substance name and CASRN). I did not find a reference to this
                chemical substance and have no knowledge of public information that
                would indicate that the chemical is being manufactured or imported
                by anyone for a commercial purpose in the United States. [provide
                date].''
                 (2) Leave manufacturing site. Does this particular chemical
                substance leave the site of manufacture (including import) in any form,
                e.g., as a product, effluent, emission? If yes, please explain what
                measures have been taken to guard against the discovery of its
                identity.
                 (3) Chemical identity. If the chemical substance leaves the site in
                a form that is available to the public or your competitors, can the
                chemical identity be readily discovered by analysis of the substance
                (e.g., product, effluent, emission), in light of existing technologies
                and any costs, difficulties, or limitations associated with such
                technologies? Please explain why or why not.
                 (4) Chemical name. Would disclosure of the specific chemical name
                release confidential process information? If yes, please explain.
                 (g) Joint submissions. If a primary submitter asks a secondary
                submitter to provide information directly to EPA in a joint submission
                under Sec. Sec. 705.15(b)(1)(i) and 705.18(b)(2)(i), only the primary
                submitter may assert a confidentiality claim for the data elements that
                it directly submits to EPA. The primary submitter must substantiate
                those claims that are not exempt under paragraph (b)(2) of this
                section. The secondary submitter is responsible for asserting all
                confidentiality claims for the data elements that it submits directly
                to EPA and for substantiating those claims that are not exempt under
                paragraph (b)(3) of this section.
                 (h) No claim of confidentiality. Except for the chemical identity
                on article importer forms submitted under Sec. 705.18(a), information
                not claimed as confidential business information in accordance with the
                requirements of this section may be made public (e.g., by publication
                of specific chemical name and CASRN on the public portion of the TSCA
                Inventory). EPA will provide advance public notice of specific chemical
                identities to be added to the public portion of the TSCA Inventory.
