                Significant New Use Rules on Certain Chemical Substances (21-4.F)
                AGENCY: Environmental Protection Agency (EPA).
                ACTION: Proposed rule.
                -----------------------------------------------------------------------
                SUMMARY: EPA is proposing significant new use rules (SNURs) under the
                Toxic Substances Control Act (TSCA) for chemical substances that were
                the subject of premanufacture notices (PMNs). The chemical substances
                received ``not likely to present an unreasonable risk'' determinations
                pursuant to TSCA. The SNURs require persons who intend to manufacture
                (defined by statute to include import) or process any of these chemical
                substances for an activity that is proposed as a significant new use by
                this rulemaking to notify EPA at least 90 days before commencing that
                activity. The required notification initiates EPA's evaluation of the
                use, under the conditions of use for that chemical substance. In
                addition, the manufacture or processing for the significant new use may
                not commence until EPA has
                [[Page 24399]]
                conducted a review of the required notification, made an appropriate
                determination regarding that notification, and taken such actions as
                required by that determination.
                DATES: Comments must be received on or before May 8, 2024.

                SUPPLEMENTARY INFORMATION:
                I. Executive Summary
                A. What is the Agency's authority for taking this action?
                 TSCA section 5(a)(2) (15 U.S.C. 2604(a)(2)) authorizes EPA to
                determine that a use of a chemical substance is a ``significant new
                use.'' EPA must make this determination by rule after considering all
                relevant factors, including the factors in TSCA section 5(a)(2) (see
                also the discussion in Unit II.).
                B. What action is the Agency taking?
                 EPA is proposing SNURs for chemical substances that were the
                subject of PMNs as discussed in Unit III. These SNURs, if finalized as
                proposed, would require persons who intend to manufacture or process
                any of these chemical substances for an activity that is designated as
                a significant new use to notify EPA at least 90 days before commencing
                that activity.
                C. Does this action apply to me?
                1. General Applicability
                 This action applies to you if you manufacture, process, or use the
                chemical substances contained in this proposed rule. 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:
                 Manufacturers or processors of one or more subject
                chemical substances (NAICS codes 325 and 324110), e.g., chemical
                manufacturing and petroleum refineries.
                2. Applicability to Importers and Exporters
                 This action may also apply to certain entities through pre-existing
                import certification and export notification rules under TSCA (https://www.epa.gov/tsca-import-export-requirements).
                 Chemical importers are subject to the import provisions in TSCA
                section 13 (15 U.S.C. 2612), the requirements promulgated at 19 CFR
                12.118 through 12.127; see also 19 CFR 127.28, and the EPA policy in
                support of import certification at 40 CFR part 707, subpart B. Chemical
                importers must certify that the shipment of the chemical substance
                complies with all applicable rules and orders under TSCA, including
                regulations issued under TSCA sections 5, 6, 7 and title IV.
                 Pursuant to 40 CFR 721.20, any persons who export or intend to
                export a chemical substance that is the subject of this proposed rule
                on or after May 8, 2024 are subject to the export notification
                provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) and must comply
                with the export notification requirements in 40 CFR part 707, subpart
                D.
                D. What are the incremental economic impacts of this action?
                 EPA has evaluated the potential costs of establishing significant
                new use notice (SNUN) reporting requirements for potential
                manufacturers (including importers) and processors of the chemical
                substances subject to these proposed SNURs. This analysis, which is
                available in the docket, is briefly summarized here.
                1. Estimated Costs for SNUN Submissions
                 If a SNUN is submitted, costs are an estimated $26,700 per SNUN
                submission for large business submitters and $11,000 for small business
                submitters. These estimates include the cost to prepare and submit the
                SNUN (including registration for EPA's Central Data Exchange (CDX)),
                and the payment of a user fee. Businesses that submit a SNUN would be
                subject to either a $19,020 user fee required by 40 CFR
                700.45(c)(2)(ii) and (d), or, if they are a small business as defined
                at 13 CFR 121.201, a reduced user fee of $3,300 (40 CFR
                700.45(c)(1)(ii) and (d)) per fiscal year 2022. The costs of submission
                for SNUNs will not be incurred by any company unless a company decides
                to pursue a significant new use as defined in these SNURs.
                Additionally, these estimates reflect the costs and fees as they are
                known at the time of this rulemaking.
                2. Estimated Costs for Export Notifications
                 EPA has also evaluated the potential costs associated with the
                export notification requirements under TSCA section 12(b) and the
                implementing regulations at 40 CFR part 707, subpart D. For persons
                exporting a substance that is the subject of a SNUR, a one-time notice
                to EPA must be provided for the first export or intended export to a
                particular country. The total costs of export notification will vary by
                chemical, depending on the number of required notifications (i.e., the
                number of countries to which the chemical is exported). While EPA is
                unable to make any estimate of the likely number of export
                notifications for the chemical substances covered by these SNURs, as
                stated in the accompanying economic analysis, the estimated cost of the
                export notification requirement on a per unit basis is approximately
                $106.
                E. What should I consider as I prepare my comments for EPA?
                1. Submitting CBI
                 Do not submit CBI to EPA through email or https://www.regulations.gov. If you wish to include CBI in your comment, please
                follow the applicable instructions at https://www.epa.gov/dockets/commenting-epa-dockets#rules and clearly mark the information that you
                claim to be CBI. Information so marked will not be disclosed except in
                accordance with procedures set forth in 40 CFR parts 2 and 704.
                2. Tips for Preparing Your Comments

                II. Background
                 This unit provides general information about SNURs. For
                [[Page 24400]]
                additional information about EPA's new chemical program go to https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca.
                A. Significant New Use Determination Factors
                 TSCA section 5(a)(2) states that EPA's determination that a use of
                a chemical substance is a significant new use must be made after
                consideration of all relevant factors, including:
                 The projected volume of manufacturing and processing of a
                chemical substance.
                 The extent to which a use changes the type or form of
                exposure of human beings or the environment to a chemical substance.
                 The extent to which a use increases the magnitude and
                duration of exposure of human beings or the environment to a chemical
                substance.
                 The reasonably anticipated manner and methods of
                manufacturing, processing, distribution in commerce, and disposal of a
                chemical substance.
                 In determining what would constitute a significant new use for the
                chemical substances that are the subject of these SNURs, EPA considered
                relevant information about the toxicity of the chemical substances, and
                potential human exposures and environmental releases that may be
                associated with the substances, in the context of the four bulleted
                TSCA section 5(a)(2) factors listed in this unit and discussed in Unit
                III.
                 These proposed SNURs include PMN substances that received a ``not
                likely to present an unreasonable risk'' determination in TSCA section
                5(a)(3)(c). During its review of these chemicals, EPA identified
                certain conditions of use that are not intended by the submitters, but
                reasonably foreseen to occur. EPA is proposing to designate those
                reasonably foreseen conditions of use as well as certain other
                circumstances of use as significant new uses.
                B. Rationale and Objectives of the SNURs
                1. Rationale
                 Under TSCA, no person may manufacture a new chemical substance or
                manufacture or process a chemical substance for a significant new use
                until EPA makes a determination as described in TSCA section 5(a) and
                takes any required action. The issuance of a SNUR is not a risk
                determination itself, only a notification requirement for ``significant
                new uses,'' so that the Agency has the opportunity to review the SNUN
                for the significant new use and make a TSCA section 5(a)(3) risk
                determination.
                 During review of the PMNs submitted for the chemical substances
                that are the subject of these proposed SNURs and as further discussed
                in Unit III., EPA identified certain other conditions of use, in
                addition to those conditions of use intended by the submitter. EPA has
                determined that the chemical under the conditions of use is not likely
                to present an unreasonable risk. However, EPA has not assessed risks
                associated with certain conditions of use. EPA is proposing to
                designate these other circumstances of use as significant new uses. As
                a result, those significant new uses cannot occur without going through
                a separate, subsequent EPA review and determination process associated
                with a SNUN.
                2. Objectives
                 EPA is proposing these SNURs because the Agency wants:
                 To be able to complete its review and determination on
                each of the PMN substances, while deferring analysis on the significant
                new uses proposed in these rules unless and until the Agency receives a
                SNUN.
                 To have an opportunity to review and evaluate data
                submitted in a SNUN before the submitter begins manufacturing or
                processing a listed chemical substance for the described significant
                new use.
                 To be obligated to make a determination under TSCA section
                5(a)(3) regarding the use described in the SNUN, under the conditions
                of use. The Agency will either determine under TSCA section 5(a)(3)(C)
                that the significant new use is not likely to present an unreasonable
                risk, including an unreasonable risk to a potentially exposed or
                susceptible subpopulation identified as relevant by the Administrator
                under the conditions of use, or make a determination under TSCA section
                5(a)(3)(A) or (B) and take the required regulatory action associated
                with the determination, before manufacture or processing for the
                significant new use of the chemical substance can occur.
                 Issuance of a proposed SNUR for a chemical substance does not
                signify that the chemical substance is listed on the TSCA Chemical
                Substance Inventory (TSCA Inventory). Guidance on how to determine if a
                chemical substance is on the TSCA Inventory is available at https://
                www.epa.gov/tsca-inventory.
                C. Significant New Uses Claimed as CBI
                 EPA is proposing to establish certain significant new uses which
                have been claimed as CBI subject to Agency confidentiality regulations
                at 40 CFR part 2 and 40 CFR part 720, subpart E. Absent a final
                determination or other disposition of the confidentiality claim under
                40 CFR part 2 procedures, EPA is required to keep this information
                confidential. EPA promulgated a procedure to deal with the situation
                where a specific significant new use is CBI, at 40 CFR 721.1725(b)(1)
                and has referenced it to apply to other SNURs.
                 Under these procedures a manufacturer or processor may request EPA
                to determine whether a specific use would be a significant new use
                under the rule. The manufacturer or processor must show that it has a
                bona fide intent to manufacture or process the chemical substance and
                must identify the specific use for which it intends to manufacture or
                process the chemical substance. If EPA concludes that the person has
                shown a bona fide intent to manufacture or process the chemical
                substance, EPA will tell the person whether the use identified in the
                bona fide submission would be a significant new use under the rule.
                Since most of the chemical identities of the chemical substances
                subject to these SNURs are also CBI, manufacturers and processors can
                combine the bona fide submission under the procedure in 40 CFR
                721.1725(b)(1) with that under 40 CFR 721.11 into a single step.
                 If EPA determines that the use identified in the bona fide
                submission would not be a significant new use, i.e., the use does not
                meet the criteria specified in the rule for a significant new use, that
                person can manufacture or process the chemical substance so long as the
                significant new use trigger is not met. In the case of a production
                volume trigger, this means that the aggregate annual production volume
                does not exceed that identified in the bona fide submission to EPA.
                Because of confidentiality concerns, EPA does not typically disclose
                the actual production volume that constitutes the use trigger. Thus, if
                the person later intends to exceed that volume, a new bona fide
                submission would be necessary to determine whether that higher volume
                would be a significant new use.
                D. Applicability of General Provisions
                 General provisions for SNURs appear in 40 CFR part 721, subpart A.
                These provisions describe persons subject to SNURs, recordkeeping
                requirements, exemptions to reporting requirements, and applicability
                of the rule to uses occurring before the effective date of the rule.
                Pursuant to 40 CFR 721.1(c), persons subject to SNURs must comply with
                the same requirements and EPA regulatory procedures as submitters of
                PMNs under TSCA section 5(a)(1)(A). In particular, these requirements
                include
                [[Page 24401]]
                the information submission requirements of TSCA sections 5(b) and
                5(d)(1), the exemptions authorized by TSCA sections 5(h)(1), 5(h)(2),
                5(h)(3), and 5(h)(5) and the regulations at 40 CFR part 720. In
                addition, provisions relating to user fees appear at 40 CFR part 700.
                 Once EPA receives a SNUN, EPA must either determine that the
                intended use is not likely to present an unreasonable risk of injury
                under the conditions of use for the chemical substance or take such
                regulatory action as is associated with an alternative determination
                under TSCA section 5 before the manufacture (including import) or
                processing for the significant new use can commence. If EPA determines
                that the intended use of the chemical substance is not likely to
                present an unreasonable risk, EPA is required under TSCA section 5(g)
                to make public, and submit for publication in the Federal Register, a
                statement of EPA's findings.
                 As discussed in Unit I.C.2., persons who export or intend to export
                a chemical substance identified in a proposed or final SNUR are subject
                to the export notification provisions of TSCA section 12(b), and
                persons who import a chemical substance identified in a final SNUR are
                subject to the TSCA section 13 import certification requirements. See
                also https://www.epa.gov/tsca-import-export-requirements.
                E. Applicability of the Proposed SNURs to Uses Occurring Before the
                Effective Date of the Final Rule
                 To establish a significant new use, EPA must determine that the use
                is not ongoing. The chemical substances subject to this proposed rule
                have undergone premanufacture review. In cases where EPA has not
                received a notice of commencement (NOC) and the chemical substance has
                not been added to the TSCA Inventory, no person may commence such
                activities without first submitting a PMN. Therefore, for chemical
                substances for which an NOC has not been submitted, EPA concludes that
                the designated significant new uses are not ongoing. The identities of
                many of the chemical substances subject to this proposed rule have been
                claimed as confidential per 40 CFR 720.85 and the PMN submitter did not
                intend to engage in the other circumstances of use that are designated
                as significant new uses for the chemical substances subject to the
                proposed rule. Based on this, the Agency believes that it is highly
                unlikely that any of the significant new uses described in the
                regulatory text of this proposed rule are ongoing.
                 When the chemical substances identified in this proposed rule are
                added to the TSCA Inventory, EPA recognizes that, before the rule is
                effective, other persons might engage in a use that has been identified
                as a significant new use. Persons who begin manufacture or processing
                of the chemical substances for a significant new use identified on or
                after the designated cutoff date specified in Unit III.A. would have to
                cease any such activity upon the effective date of the final rule. To
                resume their activities, these persons would have to first comply with
                all applicable SNUR notification requirements and EPA would have to
                take action under TSCA section 5 allowing manufacture or processing to
                proceed.
                F. Important Information About SNUN Submissions
                1. SNUN Submissions
                 SNUNs must be submitted on EPA Form No. 7710-25, generated using e-
                PMN software, and submitted to the Agency in accordance with the
                procedures set forth in 40 CFR 720.40 and 721.25. E-PMN software is
                available electronically at https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca.
                2. Development and Submission of Information
                 EPA recognizes that TSCA section 5 does not require development of
                any particular new information (e.g., generating test data) before
                submission of a SNUN. There is an exception: If a person is required to
                submit information for a chemical substance pursuant to a rule, order
                or consent agreement under TSCA section 4, then TSCA section 5(b)(1)(A)
                requires such information to be submitted to EPA at the time of
                submission of the SNUN.
                 In the absence of a rule, TSCA order, or consent agreement under
                TSCA section 4 covering the chemical substance, persons are required
                only to submit information in their possession or control and to
                describe any other information known to or reasonably ascertainable by
                them (see 40 CFR 720.50). However, upon review of PMNs and SNUNs, the
                Agency has the authority to require appropriate testing. Unit IV. lists
                potentially useful information for all SNURs listed here. Descriptions
                are provided for informational purposes. The potentially useful
                information identified in Unit IV. will be useful to EPA's evaluation
                in the event that someone submits a SNUN for the significant new use.
                Companies who are considering submitting a SNUN are encouraged, but not
                required, to develop the information on the substance, which may assist
                with EPA's analysis of the SNUN.
                 EPA strongly encourages persons, before performing any testing, to
                consult with the Agency pertaining to protocol selection. Furthermore,
                pursuant to TSCA section 4(h), which pertains to reduction of testing
                in vertebrate animals, EPA encourages consultation with the Agency on
                the use of alternative test methods and strategies (also called New
                Approach Methodologies, or NAMs), if available, to generate the
                recommended test data. EPA encourages dialog with Agency
                representatives to help determine how best the submitter can meet both
                the data needs and the objective of TSCA section 4(h). For more
                information on alternative test methods and strategies to reduce
                vertebrate animal testing, visit https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/alternative-test-methods-and-strategies-reduce.
                 The potentially useful information described in Unit III. may not
                be the only means of providing information to evaluate the chemical
                substance associated with the significant new uses. However, submitting
                a SNUN without any test data may increase the likelihood that EPA will
                take action under TSCA sections 5(e) or 5(f). EPA recommends that
                potential SNUN submitters contact EPA early enough so that they will be
                able to conduct the appropriate tests.
                 SNUN submitters should be aware that EPA will be better able to
                evaluate SNUNs which provide detailed information on the following:
                 Human exposure and environmental release that may result
                from the significant new use of the chemical substances.
                III. Chemical Substances Subject to These Proposed SNURs
                A. What is the designated cutoff date for determining whether the new
                use is ongoing for these chemical substances?
                 EPA designates April 8, 2024 as the cutoff date for determining
                whether the new use is ongoing. This designation is explained in more
                detail in Unit II.D.
                B. What information is provided for each chemical substance?
                 For each chemical substance identified in Unit III.C., EPA provides
                the following information:
                 PMN number (the proposed CFR citation assigned in the
                regulatory text section of this document).
                 Chemical name (generic name if the specific name is
                claimed as CBI).
                [[Page 24402]]
                 Chemical Abstracts Service Registry Number (CASRN) (if
                assigned for non-confidential chemical identities).
                 Basis for the SNUR.
                 Potentially useful information.
                 The regulatory text section of this document specifies the
                activities designated as significant new uses. Certain new uses,
                including production volume limits and other uses designated in the
                proposed rules, may be claimed as CBI.
                 The chemical substances that are the subject of these proposed
                SNURs have undergone premanufacture review. In addition to those
                conditions of use intended by the submitter, EPA has identified certain
                other circumstances of use. EPA has preliminarily determined that the
                chemicals under their conditions of use are not likely to present an
                unreasonable risk. However, EPA has not assessed risks associated with
                the other circumstances of use for these chemicals. EPA is proposing to
                designate these other circumstances of use as significant new uses. As
                a result, those significant new uses cannot occur without first going
                through a separate, subsequent EPA review and determination process
                associated with a SNUN.
                C. Which chemical substances are subject to this proposed rule?
                 The substances subject to the proposed rules in this document are
                as follows:
                PMN Number (Proposed CFR Citation): P-16-449 (40 CFR 721.11799)
                 Chemical Name: 2,7-Decadienal, (2E,7Z)-.
                 CASRN: 52711-52-1.
                 Basis for action: The PMN states that the use of the PMN substance
                will be in cosmetics and as a fragrance for scented papers, detergents,
                candles, etc. Based on estimated physical/chemical properties of the
                PMN substance, submitted test data on the new chemical substance,
                comparison to analogous aldehydes, and comparison to structurally
                analogous chemical substances, EPA has identified concerns for systemic
                and developmental effects, skin sensitization, skin irritation, eye
                irritation, severe respiratory tract irritation, and aquatic toxicity
                if the chemical substance is not used following the limitations noted.
                The conditions of use of the PMN substance as described in the PMN
                include the following protective measures:
                 No processing of the PMN substance to a concentration of
                greater than or equal to 1.0% in the final end use formulation; and
                 No release of the PMN substance resulting in surface water
                concentrations that exceed 1 ppb.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of these protective measures.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                and environmental effects of the PMN substance if a manufacturer or
                processor is considering submitting a SNUN for a significant new use
                that will be designated by this SNUR. EPA has determined that the
                results of specific target organ toxicity, reproductive toxicity, and
                aquatic toxicity testing may be potentially useful to characterize the
                health and environmental effects of the PMN substance.
                PMN Number (Proposed CFR Citation): P-16-512 (40 CFR 721.11800)
                 Chemical Name: Fatty acid dimers, polymer with acrylic acid and
                pentaerythritol reaction products (generic).
                 CASRN: Not available.
                 Basis for action: The PMN states that the use of the PMN substance
                will be as a component of UV curable printing inks. Based on estimated
                physical/chemical properties of the PMN substance, test data on a
                component of the new chemical substance and a potential metabolite, and
                comparison to structurally analogous chemical substances, EPA has
                identified concerns for skin and eye corrosion, skin and respiratory
                tract sensitization, systemic effects, nasal effects, and reproductive
                and developmental toxicity if the chemical substance is not used
                following the limitations noted. The conditions of use of the PMN
                substance as described in the PMN include the following protective
                measures:
                 Use of the PMN substance only as a component of UV curable
                printing inks; and
                 Use of a National Institute for Occupational Safety and
                Health (NIOSH)-certified respirator with an Assigned Protection Factor
                (APF) of at least 50, or 1,000 in spray applications, where there is a
                potential for inhalation exposure.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of these protective measures.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                effects of the PMN substance if a manufacturer or processor is
                considering submitting a SNUN for a significant new use that will be
                designated by this SNUR. EPA has determined that the results of eye
                damage, reproductive toxicity (developmental effects), skin
                sensitization, and specific target organ toxicity testing may be
                potentially useful to characterize the health effects of the PMN
                substance.
                PMN Number (Proposed CFR Citation): P-17-115 (40 CFR 721.11801)
                 Chemical Name: Aminoalkyl alkoxysilane (generic).
                 CASRN: Not available.
                 Basis for action: The PMN states that the use of the PMN substance
                will be as an adhesion promoter for coating formulations. Based on the
                estimated physical/chemical properties of the PMN substance and
                comparison to analogous chemical substances, EPA has identified
                concerns for eye and respiratory tract irritation, developmental
                toxicity, and lung toxicity if the chemical substance is not used
                following the limitations noted. The condition of use of the PMN
                substance as described in the PMN includes the following protective
                measure:
                 No consumer use of the PMN substance.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of this protective measure.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                effects of the PMN substance if a manufacturer or processor is
                considering submitting a SNUN for a significant new use that will be
                designated by this SNUR. EPA has determined that the results of
                specific target organ toxicity and reproductive/developmental toxicity
                testing may be potentially useful to characterize the health effects of
                the PMN substance.
                PMN Number (Proposed CFR Citation): P-18-36 (40 CFR 721.11802)
                 Chemical Name: Siloxanes and Silicones, di-Me, 3-[3-carboxy-2(or
                3)-(octenyl)-1-oxopropoxy]propyl group-terminated.
                 CASRN: 403616-34-2.
                 Basis for action: The PMN states that the generic (non-
                confidential) use of the PMN substance will be as a water repellant.
                Based on estimated physical/chemical properties of the PMN substance
                and comparison to structurally analogous chemical substances, EPA has
                identified concerns for lung effects, systemic effects, and skin
                irritation if the chemical substance is not used following the
                limitations noted. The condition of use of the PMN substance as
                described in the PMN
                [[Page 24403]]
                includes the following protective measure:
                 No manufacturing, processing, or use of the PMN substance
                in a manner that results in inhalation exposure.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of this protective measure.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                effects of the PMN substance if a manufacturer or processor is
                considering submitting a SNUN for a significant new use that will be
                designated by this SNUR. EPA has determined that the results of
                specific target organ toxicity and skin irritation testing may be
                potentially useful to characterize the health effects of the PMN
                substance.
                PMN Number (Proposed CFR Citation): P-18-263 (40 CFR 721.11803)
                 Chemical Name: Mixed alkyl esters-, polymer with N1-(2-aminoethyl)-
                l,2-ethanediamine, aziridine, N-acetyl derivs., acetates (salts)
                (generic).
                 CASRN: Not available.
                 Basis for action: The PMN states that the generic (non-
                confidential) use of the PMN substance will be as a solution additive.
                Based on estimated physical/chemical properties of the PMN substance,
                comparison to structurally analogous chemical substances, and
                comparison to analogous polycationic polymers, EPA has identified
                concerns for lung effects, irritation to the skin, eyes, and
                respiratory tract, and aquatic toxicity if the new chemical substance
                is not used following the limitation noted. The condition of use of the
                PMN substance as described in the PMN includes the following protective
                measure:
                 No release of the PMN substance resulting in surface water
                concentrations that exceed 5 ppb.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of this protective measure.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                and environmental effects of the PMN substance if a manufacturer or
                processor is considering submitting a SNUN for a significant new use
                that will be designated by this SNUR. EPA has determined that the
                results of specific target organ toxicity, pulmonary effects, and
                aquatic toxicity testing may be potentially useful to characterize the
                health and environmental effects of the PMN substance.
                PMN Number (Proposed CFR Citation): P-18-336 (40 CFR 721.11804)
                 Chemical Name: Propanedioic acid, 2,2-bis(hydroxymethyl)-, 1,3-
                dihexyl ester.
                 CASRN: 2222732-45-6.
                 Basis for action: The PMN states that the use of the PMN substance
                will be as an intermediate. Based on estimated physical/chemical
                properties of the PMN substance, comparison to analogous chemical
                substances, and comparison to analogous esters, EPA has identified
                concerns for systemic effects, eye irritation, and aquatic toxicity if
                the new chemical substance is not used following the limitations noted.
                The condition of use of the PMN substance as described in the PMN
                includes the following protective measure:
                 No release of the PMN substance resulting in surface water
                concentrations that exceed 54 ppb.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of this protective measure.

                irritation and eye damage testing may be potentially useful to
                characterize the health effects of the PMN substance.
                PMN Number (Proposed CFR Citation): P-20-146 (40 CFR 721.11826)
                 Chemical Name: Alkanoic acid, alkyl, carbopolycyclic alkyl ester
                (generic).
                 CASRN: Not available.
                 Basis for action: The PMN states that the generic (non-
                confidential) use of the PMN substance will be as an insulating
                material for electrical parts. Based on estimated physical/chemical
                properties of the PMN substance, comparison to structurally analogous
                chemical substances EPA has identified concerns for corrosion, skin,
                eye, respiratory tract irritation, skin sensitization, and aquatic
                toxicity if the chemical substance is not used following the
                limitations noted. The conditions of use of the PMN substance as
                described in the PMN include the following protective measures:
                 No manufacturing, processing, or use of the PMN substance
                in a manner that results in worker inhalation exposure; and
                 No release of the PMN substance resulting in surface water
                concentrations that exceed 13 ppb.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of these protective measures.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                and environmental effects of the PMN substance if a manufacturer or
                processor is considering submitting a SNUN for a significant new use
                that will be designated by this SNUR. EPA has determined that the
                results of skin sensitization and aquatic toxicity testing may be
                potentially useful to characterize the health and environmental effects
                of the PMN substance.
                PMN Number (Proposed CFR Citation): P-20-161 (40 CFR 721.11827)
                 Chemical Name: Propanedioic acid, 2-methylene-, 1,3-diethyl ester,
                polymer with 1,4-butanediol.
                 CASRN: 2364431-09-2.
                 Basis for action: The PMN states that the use of the PMN substance
                will be as a crosslinker additive used in waterborne emulsions and as a
                film former or crosslinker additive used in coatings and adhesives.
                Based on the estimated physical/chemical properties of the PMN
                substance, comparison to analogous chemical substances, and comparison
                to analogous acrylates/methacrylates, EPA has identified concerns skin,
                respiratory tract, and eye irritation, skin sensitization, local
                stomach effects, and acute inhalation toxicity if the chemical
                substance is not used following the limitations noted. The condition of
                use of the PMN substance as described in the PMN includes the following
                protective measure:
                 No consumer use of the PMN substance.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of this protective measure.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                effects of the PMN substance if a manufacturer or processor is
                considering submitting a SNUN for a significant new use that will be
                designated by this SNUR. EPA has determined that the results of skin
                irritation, sensitization, and eye damage testing may be potentially
                useful to characterize the health effects of the PMN substance.
                PMN Number (Proposed CFR Citation): P-21-12 (40 CFR 721.11828)
                 Chemical Name: Multialkylbicycloalkenyl substituted propanenitrile
                (generic).
                 CASRN: Not available.
                 Basis for action: The PMN states that the generic (non-
                confidential) use of the PMN substance will be as a fragrance
                ingredient. Based on estimated physical/chemical properties of the PMN
                substance, submitted test data on the new chemical substance,
                comparison to analogous neutral organics, and comparison to
                structurally analogous chemical substances, EPA has identified concerns
                for eye irritation, acute toxicity, liver effects, and aquatic toxicity
                if the chemical substance is not used following the limitations noted.
                The condition of use of the PMN substance as described in the PMN
                includes the following protective measure:
                 No manufacture for any use greater than 10,000 kilograms
                per year of the PMN substance.
                 The proposed SNUR would designate as a ``significant new use'' the
                absence of this protective measure.
                 Potentially Useful Information: EPA has determined that certain
                information may be potentially useful to characterize the human health
                and environmental effects of the PMN substance if a manufacturer or
                processor is considering submitting a SNUN for a significant new use
                that will be designated by this SNUR. EPA has determined that the
                results of acute toxicity, specific target organ toxicity, and chronic
                aquatic toxicity testing may be potentially useful to characterize the
                health and environmental effects of the PMN substance.
                IV. Statutory and Executive Order Reviews
                 Additional information about these statutes and Executive orders
                can be found at https://www.epa.gov/laws-regulations-and-executive-orders.
                A. Executive Order 12866: Regulatory Planning and Review and Executive
                Order 14094: Modernizing Regulatory Review
                 This action proposes to establish SNURs for new chemical substances
                that were the subject of PMNs. The Office of Management and Budget
                (OMB) has exempted these types of actions from review under Executive
                Order 12866 (58 FR 51735, October 4, 1993), as amended by Executive
                Order 14094 (88 FR 21879, April 11, 2023).
                [[Page 24409]]
                B. Paperwork Reduction Act (PRA)
                 According to the PRA (44 U.S.C. 3501 et seq.), an agency may not
                conduct or sponsor, and a person is not required to respond to a
                collection of information that requires OMB approval under PRA, unless
                it has been approved by OMB and displays a currently valid OMB control
                number. The OMB control numbers for EPA's regulations in title 40 of
                the CFR, after appearing in the Federal Register, are listed in 40 CFR
                part 9, and included on the related collection instrument or form, if
                applicable.
                 The information collection requirements related to SNURs have
                already been approved by OMB pursuant to PRA under OMB control number
                2070-0038 (EPA ICR No. 1188). This action does not impose any burden
                requiring additional OMB approval. If an entity were to submit a SNUN
                to the Agency, the annual burden is estimated to average between 30 and
                170 hours per submission. This burden estimate includes the time needed
                to review instructions, search existing data sources, gather and
                maintain the data needed, and complete, review, and submit the required
                SNUN.
                 EPA always welcomes your feedback on the burden estimates. Send any
                comments about the accuracy of the burden estimate, and any suggested
                methods for improving the collection instruments or instruction or
                minimizing respondent burden, including through the use of automated
                collection techniques.
                C. Regulatory Flexibility Act (RFA)
                 I certify that this action will not have a significant economic
                impact on a substantial number of small entities under the RFA (5
                U.S.C. 601 et seq.). The requirement to submit a SNUN applies to any
                person (including small or large entities) who intends to engage in any
                activity described in the final rule as a ``significant new use.''
                Because these uses are ``new,'' based on all information currently
                available to EPA, EPA has concluded that no small or large entities
                presently engage in such activities.
                 A SNUR requires that any person who intends to engage in such
                activity in the future must first notify EPA by submitting a SNUN.
                Although some small entities may decide to pursue a significant new use
                in the future, EPA cannot presently determine how many, if any, there
                may be. However, EPA's experience to date is that, in response to the
                promulgation of SNURs covering over 1,000 chemicals, the Agency
                receives only a small number of notices per year. For example, the
                number of SNUNs received was 16 in Federal fiscal year (FY) FY2018,
                five in FY2019, seven in FY2020, and 13 in FY2021, 11 in FY2022, and 15
                in FY2023, and only a fraction of these submissions were from small
                businesses.
                 In addition, the Agency currently offers relief to qualifying small
                businesses by reducing the SNUN submission fee from $19,020 to $3,330.
                This lower fee reduces the total reporting and recordkeeping cost of
                submitting a SNUN to about $11,164 per SNUN submission for qualifying
                small firms. Therefore, the potential economic impacts of complying
                with these proposed SNURs are not expected to be significant or
                adversely impact a substantial number of small entities. In a SNUR that
                published in the Federal Register of June 2, 1997 (62 FR 29684) (FRL-
                5597-1), the Agency presented its general determination that SNURs are
                not expected to have a significant economic impact on a substantial
                number of small entities, which was provided to the Chief Counsel for
                Advocacy of the Small Business Administration.
                D. Unfunded Mandates Reform Act (UMRA)
                 Based on EPA's experience with proposing and finalizing SNURs,
                State, local, and Tribal governments have not been impacted by these
                rulemakings, and EPA does not have any reasons to believe that any
                State, local, or Tribal government will be impacted by this action. As
                such, EPA has determined that this action does not impose any
                enforceable duty, contain any unfunded mandate, or otherwise have any
                effect on small governments subject to the requirements of UMRA
                sections 202, 203, 204, or 205 (2 U.S.C. 1531-1538 et seq.).
                E. Executive Order 13132: Federalism
                 This action will not have federalism implications as specified in
                Executive Order 13132 (64 FR 43255, August 10, 1999), because it is not
                expected to have a substantial direct effect 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. Accordingly, the requirements of Executive Order 13132 do
                not apply to this action.
                F. Executive Order 13175: Consultation and Coordination With Indian
                Tribal Governments
                 This action will not have Tribal implications as specified in
                Executive Order 13175 (65 FR 67249, November 9, 2000), because it is
                not expected to have substantial direct effects on Indian Tribes,
                significantly or uniquely affect the communities of Indian Tribal
                governments and does not involve or impose any requirements that affect
                Indian Tribes. Accordingly, the requirements of Executive Order 13175
                do not apply to this action.
                G. Executive Order 13045: Protection of Children From Environmental
                Health Risks and Safety Risks
                 This action is not subject to Executive Order 13045 (62 FR 19885,
                April 23, 1997), because it does not concern an environmental health or
                safety risk. Since this action does not concern human health, EPA's
                2021 Policy on Children's Health also does not apply. Although the
                establishment of these SNURs do not address an existing children's
                environmental health concern because the chemical uses involved are not
                ongoing uses, SNURs require that persons notify EPA at least 90 days
                before commencing manufacture (defined by statute to include import) or
                processing of any of these chemical substances for an activity that is
                designated as a significant new use by this rulemaking. This
                notification allows EPA to assess the intended uses to identify
                potential risks and take appropriate actions before the activities
                commence.
                H. Executive Order 13211: Actions Concerning Regulations That
                Significantly Affect Energy Supply, Distribution, 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.
                I. National Technology Transfer and Advancement Act (NTTAA)
                 This action does not involve any technical standards subject to
                NTTAA section 12(d) (15 U.S.C. 272 note).
                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
                 This action does not concern human health or environmental
                conditions and therefore cannot be evaluated with respect to the
                potential for disproportionate impacts on non-white and low-income
                populations in accordance with Executive Order 12898 (59 FR 7629,
                February 16, 1994) and
                [[Page 24410]]
                Executive Order 14096 (88 FR 25251, April 26, 2023). Although this
                action does not concern human health or environmental conditions, the
                premanufacture notifications required by these SNURs allows EPA to
                assess the intended uses to identify potential disproportionate risks
                and take appropriate actions before the activities commence.
                List of Subjects in 40 CFR Part 721
                 Environmental protection, Chemicals, Hazardous substances,
                Reporting and recordkeeping requirements.
                 Dated: April 1, 2024.
                Mary Elissa Reaves,
                Director, Office of Pollution Prevention and Toxics.
                 Therefore, for the reasons stated in the preamble, EPA proposes to
                amend 40 CFR chapter I as follows:
                PART 721--SIGNIFICANT NEW USES OF CHEMICAL SUBSTANCES
                0
                1. The authority citation for part 721 continues to read as follows:
                 Authority: 15 U.S.C. 2604, 2607, and 2625(c).
                0
                2. Add Sec. Sec. 721.11799 through 721.11828 to subpart E to read as
                follows:
                Subpart E--Significant New Uses for Specific Chemical Substances
                Sec. 721.11799 2,7-Decadienal, (2E,7Z)-.
                 (a) Chemical substance and significant new uses subject to
                reporting. (1) The chemical substance identified as 2,7-decadienal,
                (2E,7Z)- (PMN P-16-449; CASRN 52711-52-1) is subject to reporting under
                this section for the significant new uses described in paragraph (a)(2)
                of this section.
                 (2) The significant new uses are:
                 (i) Industrial, commercial, and consumer activities. It is a
                significant new use to process the PMN substance to a concentration of
                greater than or equal to 1.0% in the final end use formulation.
                 (ii) Release to water. Requirements as specified in Sec.
                721.90(a)(4), (b)(4), and (c)(4), where N=1.
                 (b) Specific requirements. The provisions of subpart A of this part
                apply to this section except as modified by this paragraph (b).
                 (1) Recordkeeping. Recordkeeping requirements as specified in Sec.
                721.125(a) through (c), (i), and (k) are applicable to manufacturers
                and processors of this substance.
                 (2) Limitations or revocation of certain modification requirements.
                The provisions of Sec. 721.185 apply to this section.
                Sec. 721.11800 Fatty acid dimers, polymer with acrylic acid and
                pentaerythritol reaction products (generic).
                 (a) Chemical substance and significant new uses subject to
                reporting. (1) The chemical substance generically identified as fatty
                acid dimers, polymer with acrylic acid and pentaerythritol reaction
                products (PMN P-16-512) is subject to reporting under this section for
                the significant new uses described in paragraph (a)(2) of this section.
                 (2) The significant new uses are:
                 (i) Protection in the workplace. Requirements as specified in Sec.
                721.63(a)(4) and (5), and (c). When determining which persons are
                reasonably likely to be exposed as required for Sec. 721.63(a)(4),
                engineering control measures (e.g., enclosure of confinement of the
                operation, general and local ventilation) or administrative control
                measures (e.g., workplace policies and procedures) shall be considered
                and implemented to prevent exposure, where feasible. For purposes of
