National Emission Standards for Hazardous Air Pollutants for Polyether Polyols Production; Synthetic Organic Chemical Manufacturing Industry; Epoxy Resins Production and Non-Nylon Polyamides Production; and Petroleum Refineries

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule and final rule.

SUMMARY: The EPA is taking direct final action to amend the national emission standards for hazardous air pollutants (NESHAP) for Polyether Polyols Production; Synthetic Organic Chemical Manufacturing Industry (also known as Hazardous Organic NESHAP, or HON); Epoxy Resins Production and Non-Nylon Polyamides Production; and Petroleum Refineries. For all four of these NESHAP, this direct final rule amends the definition of equipment leaks to add the term ``connectors'' to the list of equipment that is subject to the equipment leak provisions in those NESHAP.

The remainder of this direct final rule corrects referencing errors and several equations which contained printing errors in the final NESHAP for Polyether Polyols Production (hereafter referred to as ``subpart PPP''). This direct final rule amends the description of a process change and the description of excess emissions; the requirements pertaining to submission of a request for extension of a compliance date; the storage vessel monitoring requirements; the definition of the terms epoxide, polyether polyol, and Group 2 wastewater stream; the conditions required during performance testing for batch process vents; which compounds are considered to be organic hazardous air pollutants (HAPs) for the purposes of both the maintenance wastewater and the process wastewater requirements; the information requirements for start-up, shutdown, and malfunction reports; the dates on which initial notifications are due; and the reporting requirements for other reports to clarify those requirements.

In addition to the direct final rule, in compliance with the Paperwork Reduction Act (PRA), EPA is amending as a final rule the Office of Management and Budget (OMB) approval table to list the OMB control number issued under the PRA for information collection requirements for subpart PPP.

DATES: The amendments to 40 CFR part 9 are effective on May 8, 2000. The direct final rule amendments to 40 CFR part 63 are effective on July 7, 2000 without further notice, unless the EPA receives adverse comments by June 7, 2000, or by June 22, 2000 if a public hearing is requested. See the proposed rule in this issue of the Federal Register for information on the hearing. If we receive such comments, and those comments apply to an amendment, paragraph, or section of this rule, and that provision may be addressed separately from the remainder of the rule, we will withdraw only those provisions on which we received adverse comments. We will publish a timely withdrawal in the Federal Register indicating which provisions will become effective on July 7, 2000 and which provisions are being withdrawn.

ADDRESSES: Comments. Written comments should be submitted (in duplicate, if possible) to: Air and Radiation Docket and Information

1. Why Are We Publishing These Amendments as a Direct Final Rule?

   In the direct final rule portion of this action, we are correcting printing and referencing errors. We are also revising and slightly reorganizing certain paragraphs, and we are making minor amendments to certain definitions. These changes provide clarification on a variety of provisions ranging from applicability to recordkeeping. In all instances, we believe that these changes have the potential to reduce the burden on both owners and operators of affected sources and on the State or local agency implementing the rule, although we are unable to quantify reductions in hours for these amendments. For these reasons, we view these amendments as noncontroversial and anticipate no adverse comments, and we are publishing these amendments in a direct final rule.

   If an adverse comment applies to an amendment, paragraph, or section of this direct final rule, and that provision may be addressed separately from the remainder of the rule, we will withdraw only those provisions on which we received adverse comments. In the ``Proposed Rules'' section of this Federal Register, we are publishing a separate document that will serve as the proposal for any provisions in this direct final rule on which we receive adverse comments. The EPA will publish a timely withdrawal in the Federal Register indicating which provisions will become effective and which provisions are being withdrawn. If part or all of this direct final rule is withdrawn, all public comments received will be addressed in a subsequent final rule based on the proposal in the ``Proposed Rules'' section of this Federal Register. We will not institute a second comment period on the subsequent final rule. Any parties interested in commenting must do so at this time. The nature of the changes contained in this direct final rule are such that it will benefit both industry and the States for these changes to become effective sooner, rather than later, as will be described in more detail below.

2. What Amendments Are We Making To Reflect OMB Approval of the Information Collection Request (ICR) for the NESHAP for Polyether Polyols Production?

   This final rule amends the table of currently approved Information Collection Request (ICR) control numbers issued by OMB. This final rule updates the table to list those information requirements promulgated under the NESHAP for Polyether Polyols Production, which appeared in the Federal Register on June 1, 1999 (64 FR 29420). The affected regulations are codified at 40 CFR part 63, subpart PPP. We will continue to present OMB control numbers in a consolidated table format to be codified in 40 CFR part 9 of the Agency's regulations and in each CFR volume containing EPA regulations. The table lists the section numbers with reporting and recordkeeping requirements and the current OMB control numbers. This listing of the OMB control numbers and their subsequent codification in the CFR satisfy the requirements of the Paperwork Reduction Act and OMB's implementing regulations at 5 CFR part 1320. The ICR itself was subject to public notice and comment prior to OMB's approval of the ICR. Further, because amendment of the table in part 9 is technical in nature, we believe that another notice and comment period for this amendment is unnecessary. For these reasons, we believe that there is good cause under the Administrative Procedure Act (5 U.S.C. Sec. 553(b) to amend this table without prior notice and comment.

3. What Amendments Are We Making to the Equipment Leak Definition That Affect Subparts F, W, CC, and PPP?

   In these rules, we are amending the definition of equipment leak in subparts F, W, CC, and PPP of 40 CFR part 63. In each of these NESHAP, the definition of equipment leak listed several sources from which emissions of organic HAP constitute a leak. However, ``connectors'' are not included in the list of sources of emissions that are included in the definition of the term equipment leak in any of those NESHAP.

   Affected sources subject to any of those four subparts are required to comply with the NESHAP for equipment leaks (40 CFR part 63, subpart H). In subpart H, Sec. 63.169 contains standards for pumps, valves, connectors, and agitators in heavy liquid service; instrumentation systems; and pressure relief devices in liquid service. Section 63.174 (of 40 CFR part 63, subpart H) contains standards for connectors in gas/vapor service and in light liquid service. The fact that there are specific provisions in subpart H applicable to connectors clearly demonstrates that we always intended emissions from connectors to be considered equipment leaks. In addition, the definition of equipment in Sec. 63.161 of subpart H includes connectors, providing further evidence that the definition of equipment leak should include connectors. Therefore, we are amending the definition of equipment leak in subparts F, W, CC, and PPP by adding the term ``a connector'' to the list of equipment in each of those definitions.

4. What Amendments Are We Making to Subpart PPP?

   Although this action amends portions of four separate subparts of 40 CFR part 63 (i.e., subparts F, W, CC, and PPP), the primary focus of the amendments in this action is subpart PPP, which was promulgated on June 1, 1999 (64 FR 29420). This direct final rule contains amendments and technical corrections to the requirements in subpart PPP.

   Several equations in the promulgated version of subpart PPP were printed incorrectly. This direct final rule amends the erroneous symbols in equations numbered 1, 2, 4, 5, 7, 10, and 13, to produce the originally intended equations.

   This direct final rule also corrects references in several sections of subpart PPP. References are being corrected in this direct final rule in the following paragraphs: Sec. 63.1422(b); Sec. 63.1426(d)(3)(ii); Sec. 63.1428(g)(3)(i); Sec. 63.1430(e)(1)(vi) and (vii); Sec. 63.1432(h) and (l); Sec. 63.1433(a)(5), (7), and (8); Sec. 63.1435(c); Sec. 63.1439(e)(5)(iv) and (e)(7)(ii), and in the definition of Group 2 wastewater stream.

   Two terms which are used in subpart PPP but were not defined in the final rule were added to the list in Sec. 63.1423(a) that incorporates the definitions from other subparts. Specifically, oil-water separator or organic-water separator and responsible official were added to the list and their definitions in subparts G and A, respectively, were referenced.

   In addition, the June 1, 1999 final rule contained references to 40 CFR part 63, subpart I in both Secs. 63.1422(h) and 63.1434(c). This was an error because subpart I does not apply to polyether polyols producers. Therefore, both Secs. 63.1422(h) and 63.1434(c) are removed and reserved in this direct final rule.

   The provisions in Sec. 63.1420(g) specify how changes or additions to plant sites impact whether an affected source is a new affected source or an existing affected source. Paragraph (g)(2) in Sec. 63.1420 addresses adding emission points or making process changes to an existing affected source. The provisions in Sec. 63.1420(g)(2)(i) specify that a process change or addition to an existing affected source that meets the definition of reconstruction and that occurred after September 4, 1997 causes

   [[Page 26494]]

   the entire affected source to become a new affected source. After promulgation of subpart PPP, we realized that these provisions were not consistent with our reconstruction policy for 40 CFR part 63 standards, which is contained in the general provisions for part 63 (40 CFR part 63, subpart A). The general provisions clearly distinguish between ``replacements'' and ``additions.'' The definition of reconstruction in the general provisions only addresses the ``replacement'' of equipment, while Sec. 63.5(b)(6) of the general provisions addresses additions. At promulgation, these two concepts were combined in the language for Sec. 63.1420(g)(2)(i), creating confusion and making the subpart PPP requirements inconsistent with the our general policy on ``replacements'' and ``additions.'' Therefore, in this direct final rule we are revising the provisions in Sec. 63.1420(g)(2) to clearly distinguish how the replacement of components should be handled by owners and operators, and how the addition of new components should be handled, with respect to applicability to the new or existing source requirements. In summary, if the replacement of components at an existing affected source meets the definition of reconstruction, then the affected source becomes a new affected source. If an addition is made to an existing affected source, then the addition becomes part of the existing affected source.

   Paragraph (g)(3) in Sec. 63.1420 describes how to distinguish a process change from a change that is not considered to be a ``process change,'' according to the 40 CFR part 63, subpart PPP requirements. We are amending Sec. 63.1420(g)(3) by removing the last phrase (which referred to the equipment configuration and operating conditions documented in the notification of compliance status report required by Sec. 63.1439(e)(5)), because not all equipment configurations and operating conditions are required to be reported in the notification of compliance status report. The phrase that was removed implied that unless a configuration or condition was described in the notification of compliance status report, equipment in that configuration or condition would automatically be considered to be a ``process change.'' It was not our intent that every possible equipment configuration or condition be described in the notification of compliance status report. In addition, the phrase ``changes that are not within the equipment configuration'' was replaced with the phrase ``changes that do not alter the equipment configuration,'' for reasons similar to those described above.

   Paragraph (h) in Sec. 63.1420 addresses the applicability of subpart PPP during periods of start-up, shutdown, malfunction, or nonoperation. Paragraph (h)(1) in Sec. 63.1420 specifies that the emission limitations in subpart PPP do not apply during these periods. However, paragraphs Sec. 63.1420(h)(3) and (4) contain requirements specific to periods of start-up, shutdown, and malfunction. Therefore, paragraph Sec. 63.1420(h)(1) in the direct final rule has been amended to indicate that the emission limitations in the subpart do not apply during periods of start-up, shutdown, or malfunction, except as provided in Sec. 63.1420(h)(3) and (4).

   Also, Sec. 63.1420(h)(4) requires that you must prevent or minimize excess emissions during periods of start-up, shutdown, and malfunction, and provides a description of what constitutes ``excess emissions.'' In these direct final amendments, we are changing this description from ``emissions in excess of those that would have occurred if there were no start-up, shutdown, or malfunction,'' to ``emissions greater than those allowed by the emission limitation which would apply during operational periods other than start-up, shutdown, and malfunction.'' We are making this change because we believe that the new wording is more consistent with our original intent, which was that owners or operators take steps to minimize emissions during start-up, shutdown, and malfunction. Further, we believe the revision in this direct final rule is clearer and more specific than the promulgated language.

   Paragraph (e) of Sec. 63.1422 includes the provisions for requesting a compliance extension. In the promulgated rule, this paragraph stated that a request for compliance must be submitted no later than 120 days prior to the compliance dates specified in paragraphs (b) through (d) of Sec. 63.1422. However, there are compliance dates specified in other paragraphs of subpart PPP. For instance, Sec. 63.1420(g)(2)(i) of this direct final requires that new emission points comply with the existing source requirements by 120 days after the day of initial start-up. We intended that the compliance extension provisions in Sec. 63.1422(e) apply to these other compliance dates, as well as to the compliance dates in Sec. 63.1420(b) through (d). Therefore, this direct final rule adds a phrase to make it clear that you can request a compliance extension for compliance dates that are specified in sections of subpart PPP other than Sec. 63.1420(b) through (d).

   The promulgated definition of epoxide in subpart PPP includes a description of what an epoxide is (i.e., a chemical compound consisting of a three-membered cyclic ether). The definition also states that only emissions of ethylene oxide and propylene oxide are regulated under subpart PPP. After promulgation of subpart PPP, we became aware of another epoxide, ``epichlorohydrin,'' that is used to make polyether polyols. Under the promulgated definition of epoxide, emissions of epichlorohydrin would be exempt from control. This is inconsistent with section 112(b), (c), and (d) of the CAA. Therefore, we have added epichlorohydrin to Table 4 (Known Organic HAP from Polyether Polyols Products) and have amended the definition of epoxide to include epichlorohydrin in the list of epoxides that are subject to the provisions of subpart PPP.

   In the promulgated NESHAP, the definition of polyether polyol excludes hydroxyethyl cellulose. At the time of promulgation of subpart PPP, we intended that this product, which meets the basic criteria of a polyether polyol, would be covered by the Miscellaneous Cellulose NESHAP, which we are currently developing. However, in the development of the Miscellaneous Cellulose NESHAP, we have become aware of other cellulose ether products that meet the definition of polyether polyol. Therefore, in this direct final rule we have revised the definition of polyether polyol to exclude the entire family of cellulose ethers, not just hydroxyethyl cellulose.

   The promulgated version of subpart PPP requires compliance with the HON requirements for storage vessels, with the exceptions listed in Sec. 63.1432. Section 63.1432 requires that records of all times when the storage tank is being filled be kept, in addition to the records required in Sec. 63.123 of the HON. In this direct final rule, we are making clarifications to the rule at Sec. 63.1432(q). Our intent was that the requirement to keep records of times when the storage vessel is being filled should only apply to storage vessels using a combustion, recovery, or recapture device, where the applicable monitoring plan does not specify continuous monitoring. The amended language in Sec. 63.1432(q) should make this distinction clear.

   For the purposes of both the maintenance wastewater and the process wastewater requirements in subpart PPP, we are amending Sec. 63.1433(a)(1) and (2) and (b)(1), in order to clarify which compounds are considered ``organic HAP.'' The language in Sec. 63.1433(a)(1) is

   [[Page 26495]]

   inadequate, while the language in Sec. 63.1433(a)(2) and Sec. 63.1433(b)(1) is unnecessarily complicated and difficult to interpret. The amendments in this direct final rule should make those requirements much easier to follow.

   This direct final rule also clarifies the conditions required during performance testing for process vents from batch unit operations. Section 63.1426, paragraph (c)(3)(i)(B), which contains requirements specific to process vents from batch unit operations, states that performance testing may be conducted during either absolute worst-case conditions or hypothetical worst-case conditions. However, Sec. 63.1437(a)(1) which contains general performance testing requirements for all emission sources, lists only absolute worst-case conditions as an option for performance testing at process vents from batch unit operations. This direct final rule corrects Sec. 63.1437(a)(1) by revising that paragraph to state that performance testing at both absolute and hypothetical worst-case conditions is acceptable for process vents from batch unit operations.

   Additionally, this direct final rule amends the information requirements associated with start-up, shutdown, and malfunction reports in Sec. 63.1439(b)(1)(ii). The promulgated NESHAP requires the start-up, shutdown, and malfunction report to include all of the information recorded under Sec. 63.1439(b)(1)(i)(A) through (B), and to contain the name, title, and signature of the owner or operator, or other responsible official certifying the report's accuracy. However, this is a good deal more information than is required to be specified in the general provisions in Sec. 63.10(d)(5)(i). We have decided that as long as the information recorded under Sec. 63.1439(b)(1)(i)(A) through (B) is recorded, that information need not be submitted to the Administrator. Therefore, this direct final rule references the start- up, shutdown, and malfunction reporting requirements in Sec. 63.10(d)(5)(i) and no longer includes such a long list of information to report under Sec. 63.1439(b)(1)(ii).

   This direct final rule also removes the requirement that existing sources submit an Initial Notification report. The promulgated rule lists two separate due dates in different sections of the rule for the Initial Notification report. Section 63.1439, paragraph (e)(3)(ii)(A), states that the due date for the Initial Notification report for existing sources is June 1, 2000, but Table 8 shows the date as 120 days after June 1, 1999. Neither of those two dates is appropriate, in that the first date is too soon after promulgation of subpart PPP, while the other date is too late, since it was after the due date of the Notification of Compliance Status report for equipment leaks (April 29, 2000, or 150 days after the December 1, 1999 compliance date). To be useful, the Administrator (or the delegated authorities) needs to receive the Initial Notification report with sufficient time to prepare for receipt of the Notification of Compliance Status reports. Since this direct final rule will not take effect until after the date that the Notification of Compliance Status report for equipment leaks is due for existing sources, we do not believe that the submittal of an Initial Notification report is beneficial. Therefore, we have removed all requirements related to the Initial Notification report for existing sources. The specific changes are to Sec. 63.1439(e)(3) and Table 8 of subpart PPP.

   This direct final rule also inserts some introductory language pertinent to the other reports that are due in Sec. 63.1439(e)(7) and reorganizes and renumbers the subsections of that paragraph. We are amending Table 1 of subpart PPP to clarify that although Sec. 63.10(d)(5)(i) from the general provisions applies to subpart PPP affected sources, Sec. 63.10(d)(5)(ii) (which requires immediate start- up, shutdown, or malfunction reports) does not.

5. What Are the Administrative Requirements for These Rules?

   1. Executive Order 12866

      Under Executive Order 12866 (58 FR 51735, October 4, 1993), the EPA must determine whether the regulatory action is ``significant'' and therefore subject to OMB review and the requirements of the Executive Order. The Executive Order defines ``significant regulatory action'' as one that is likely to result in a rule that may:

      (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, productivity, competition, jobs, the environment, public health or safety, or state, local, or tribal governments or communities;

      (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

      (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or

      (4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order.

      Pursuant to the terms of Executive Order 12866, it has been determined that these amendments are not a ``significant regulatory action'' because they do not meet any of the above criteria. Consequently, these rules were not submitted to OMB for review under Executive Order 12866.

   2. Executive Order 13132

      Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 10, 1999) requires EPA to develop an accountable process to ensure ``meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' ``Policies that have federalism implications'' is defined in the Executive Order to include regulations that have ``substantial direct effects on the 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.'' Under section 6 of Executive Order 13132, EPA may not issue a regulation that has federalism implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by State and local governments, or EPA consults with State and local officials early in the process of developing the regulation. The EPA also may not issue a regulation that has federalism implications and that preempts State law unless the Agency consults with State and local officials early in the process of developing the regulation.

      This direct final rule does not have federalism implications. It will not have substantial direct effects on the 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, as specified in Executive Order 13132. Thus, the requirements of section 6 of Executive Order 13132 do not apply to this direct final rule.

   3. Executive Order 13084

      Under Executive Order 13084, EPA may not issue a regulation that is not required by statute, that significantly or uniquely affects the communities of Indian tribal governments, and that imposes substantial direct compliance costs on those communities, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by the tribal governments, or EPA consults with those governments. If EPA complies by

      [[Page 26496]]

      consulting, Executive Order 13084 requires EPA to provide to OMB, in a separately identified section of the preamble to the rule, a description of the extent of EPA's prior consultation with representatives of affected tribal governments, a summary of the nature of their concerns, and a statement supporting the need to issue the regulation. In addition, Executive Order 13084 requires EPA to develop an effective process permitting elected officials and other representatives of Indian tribal governments ``to provide meaningful and timely input in the development of regulatory policies on matters that significantly or uniquely affect their communities.'' These rules do not significantly or uniquely affect the communities of Indian tribal governments. No tribal governments own or operate an affected source. Accordingly, the requirements of section 3(b) of Executive Order 13084 do not apply to these rules.

   4. Executive Order 13045

      Executive Order 13045 (62 FR 19885, April 23, 1997), applies to any rule that: (1) Is determined to be ``economically significant'' as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that the EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, the Agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency.

      The EPA interprets Executive Order 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Order has the potential to influence the regulation. These rules fall into that category only in part: the minimum rule stringency for subpart PPP is set according to a congressionally-mandated, technology-based lower limit called the ``floor,'' while a decision to increase the stringency beyond this floor can be based on risk considerations. Thus, Executive Order 13045 applies to these rules only to the extent that the Agency may consider the inherent toxicity of a regulated pollutant, and any differential impact such a pollutant may have on children's health, in deciding whether to adopt control requirements more stringent than the floor level in subpart PPP.

      These rules are not subject to Executive Order 13045 because they are not economically significant as defined in Executive Order 12866. No children's risk analysis was performed for these rules because no alternative technologies exist that would provide greater stringency at a reasonable cost. Therefore, the results of any such analysis would have no impact on the stringency decision.

   5. Unfunded Mandates Reform Act

      Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Pub. L. 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, the EPA generally must prepare a written statement, including a cost- benefit analysis, for proposed and final rules with ``Federal mandates'' that may result in expenditures to State, local, and tribal governments, in the aggregate, or by the private sector, of $100 million or more in any 1 year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires the EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost- effective, or least-burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows the EPA to adopt an alternative other than the least-costly, most cost- effective, or least-burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before the EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, it must have developed under section 203 of the UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements.

      The EPA has determined that these rules do not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or in the private sector in any 1 year. Thus, today's rules are not subject to the requirements of sections 202 and 205 of the UMRA. In addition, the EPA has determined that these rules contain no regulatory requirements that might significantly or uniquely affect small governments, because they contain no requirements that apply to such governments or impose obligations on them. Therefore, today's rules are not subject to the requirements of section 203 of the UMRA.

   6. Regulatory Flexibility Act (RFA), as Amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 USC 601 et seq.

      The RFA generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

      For purposes of assessing the impacts of this direct final on small entities, small entity is defined as : (1) A small business that has less than 750 employees and is unaffiliated with a larger domestic entity; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.

      After considering the economic impacts of these rules on small entities, we have concluded that these actions will not have a significant economic impact on a substantial number of small entities. Consistent with Small Business Administrative (SBA) size standards, a polyether polyols production facility is classified as a small entity if it has less than 750 employees and is unaffiliated with a larger domestic entity. On that basis, 7 of the 36 polyether polyol production facilities are classified as small entities (i.e., having fewer than 750 employees). The EPA determined that none of these seven small entities will experience an increase in costs that is greater than one percent of revenues, as a result of these rules. This does not qualify as a significant economic impact on a substantial number of small businesses.

   7. Paperwork Reduction Act

      The information collection requirements in the final rule were submitted for approval to OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. An Information Collection Request (ICR) document has been

      [[Page 26497]]

      prepared by EPA (ICR No. 1811.01), but, at promulgation, that ICR had not yet been approved by OMB. However, since promulgation the OMB has approved the ICR, and this final rule amends the table of currently approved ICR control numbers issued by OMB and updates the table to accurately display those information requirements not previously approved. The information collection requirements that are made effective by this action under OMB control number 2060-0415 were contained in ICR number 1811.01.

      Today's final rule will have no impact on the information collection burden estimates made previously. The direct final amendments clarify the intent of the subpart PPP and correct inadvertent omissions and minor drafting errors. Consequently, the ICR has not been revised.

   8. National Technology Transfer and Advancement Act

      Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Pub. L. 104-113, (15 U.S.C. 272 note), directs all Federal agencies to use voluntary consensus standards instead of government-unique standards in their regulatory activities unless to do so would be inconsistent with applicable law or would be otherwise impractical. Voluntary consensus standards are technical standards (e.g., material specifications, test method, sampling and analytical procedures, business practices, etc.) that are developed or adopted by one or more voluntary consensus standards bodies. Examples of organizations generally regarded as voluntary consensus standards bodies include the American Society for Testing and Materials (ASTM), the National Fire Protection Association (NFPA), and the Society of Automotive Engineers (SAE). The NTTAA requires Federal agencies like EPA to provide Congress, through OMB, with explanations when the Agency decides not to use available and applicable voluntary consensus standards.

      During the rulemaking, the Agency searched for voluntary consensus standards that might be applicable. The search has identified no applicable voluntary standards. Accordingly, the NTTAA requirement to use applicable voluntary consensus standards does not apply to these rules.

1. The Congressional Review Act

   The Congressional Review Act, 5 U.S.C. Sec. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a ``major rule'' as defined by 5 U.S.C. Sec. 804(2). This rule will be effective July 7, 2000.

      Sec. 63.1420 Applicability and designation of affected sources.

      * * * * *

      (e) * * *

      (3) Annual applicability determination for non-PMPUs that have produced a polyether polyol. Once per year beginning June 1, 2004, the owner or operator of each flexible operation unit that is not designated as a PMPU, but that has produced a polyether polyol at any time in the preceding 5-year period or since the date that the unit began production of any product, whichever is shorter, shall perform the evaluation described in paragraphs (e)(3)(i) through (iii) of this section. However, an owner or operator that does not intend to produce any elastomer product in the future, in accordance with paragraph (e)(9) of this section, is not required to perform the evaluation described in paragraphs (e)(3)(i) through (iii) of this section. * * * * *

      (9) PMPUs terminating production of all polyether polyols. If a PMPU terminates the production of all polyether polyols, and the owner or operator does not anticipate the production of any polyether polyols in the future in that PMPU, the process unit is no longer a PMPU and is not subject to this subpart after notification is made to the Administrator. This notification shall be accompanied by a rationale for why it is anticipated that no polyether polyols will be produced in the process unit in the future. * * * * *

      (g) * * *

      (1) * * *

      (i) If a group of one or more PMPUs is added to a plant site, the added group of one or more PMPUs and their associated equipment, as listed in paragraph (a)(4) of this section, shall be a new affected source and shall comply with the requirements for a new affected source in this subpart upon initial start-up or by June 1, 1999, whichever is later, if the added group of one or more PMPUs meets the criteria specified in paragraph (g)(1)(i)(A) of this section and either meets the criteria in paragraph (g)(1)(i)(B) or (C) of this section. * * * * *

      (2) Adding emission points or making process changes to existing affected sources. The provisions of paragraphs (g)(2)(i), (ii), and (iii) of this section apply to the owner or operator that adds emission points or makes process changes to an existing affected source.

      (i) If any components are replaced at an existing affected source such that the criteria specified in paragraphs (g)(2)(i)(A) and (B) of this section are met, the entire affected source shall be a new affected source and shall comply with the requirements for a new affected source upon initial start-up or by June 1, 1999, whichever is later.

      (A) The replacement of components meets the definition of reconstruction in Sec. 63.1423(b). For purposes of determining whether the fixed capital cost of the new components exceeds 50 percent of the fixed capital cost that would be required to construct an entire affected source, the equivalent capital cost shall be the entire potentially affected source; and * * * * *

      (ii) If any components are replaced at an existing affected source such that the criteria specified in paragraphs (g)(2)(i)(A) and (B) of this section are not met and that replacement of components creates one or more emission points (i.e., either newly created Group 1 emission points or emission points that change from Group 2 to Group 1) or causes any other emission point to be added (i.e., Group 2 emission points, heat exchange systems subject to Sec. 63.1435, or equipment leak components subject Sec. 63.1434), the resulting emission point(s) shall be subject to the applicable requirements for an existing affected source. The resulting emission point(s) shall be in compliance upon initial start-up or by the appropriate compliance date specified in Sec. 63.1422 (i.e., December 1, 1999 for most equipment leak components subject to Sec. 63.1434, and June 1, 2002 for emission points other than equipment leaks), whichever is later.

      (iii) If an addition or process change (not including a process change that solely replaces components) is made that creates one or more Group 1 emission points (i.e., either newly created Group 1 emission points or emission points that change group status from Group 2 to Group 1) or causes any other emission point to be added (i.e., Group 2 emission points, heat exchange systems subject to Sec. 63.1435, or equipment leak components subject to Sec. 63.1434), the resulting emission point(s) shall be subject to the applicable requirements for an existing affected source. The resulting emission point(s) shall be in compliance by initial start-up or by the appropriate compliance date specified in Sec. 63.1422 (i.e., December 1, 1999 for most equipment leak components subject to Sec. 63.1434, and June 1, 2002 for emission points other than equipment leaks), whichever is later.

      (3) Determining what are and are not process changes. For purposes of paragraph (g) of this section, examples of process changes include, but are not limited to, additions in process equipment resulting in changes in production capacity; production of a product outside the scope of the compliance demonstration; or whenever there is a replacement, removal, or addition of recovery equipment. For purposes of paragraph (g) of this section, process changes do not include: process upsets, unintentional temporary process changes, and changes that do not alter the equipment configuration and operating conditions.

      (4) Reporting requirements for owners or operators that change or add to their plant site or affected source. An owner or operator that changes or adds to their plant site or affected source, as discussed in paragraphs (g)(1) and (g)(2) of this section, shall submit a report as specified in Sec. 63.1439(e)(7)(iii).

      (h) * * *

      (1) The emission limitations set forth in this subpart and the emission limitations referred to in this subpart shall apply at all times except during periods of nonoperation of the affected source (or specific portion thereof) resulting in cessation of the emissions to

      [[Page 26499]]

      which this subpart applies. These emission limitations shall not apply during periods of start-up, shutdown, or malfunction, except as provided in paragraphs (h)(3) and (4) of this section. During periods of start-up, shutdown, or malfunction, the owner or operator shall follow the applicable provisions of the start-up, shutdown, and malfunction plan required by Sec. 63.6(e)(3). However, if a start-up, shutdown, malfunction, or period of nonoperation of one portion of an affected source does not affect the ability of a particular emission point to comply with the emission limitations to which it is subject, then that emission point shall still be required to comply with the applicable emission limitations of this subpart during the start-up, shutdown, malfunction, or period of nonoperation. For example, if there is an overpressure in the reactor area, a storage vessel that is part of the affected source would still be required to be controlled in accordance with the storage tank provisions in Sec. 63.1432. Similarly, the degassing of a storage vessel would not affect the ability of a process vent to meet the emission limitations for process vents in Secs. 63.1425 through 63.1430. * * * * *

      (4) During start-ups, shutdowns, and malfunctions when the emission limitations of this subpart do not apply pursuant to paragraphs (h)(1) through (3) of this section, the owner or operator shall implement, to the extent reasonably available, measures to prevent or minimize excess emissions to the extent practical. For purposes of this paragraph, the term ``excess emissions'' means emissions greater than those allowed by the emissions limitation which would apply during operational periods other than start-up, shutdown, and malfunction. The measures to be taken shall be identified in the applicable start-up, shutdown, and malfunction plan, and may include, but are not limited to, air pollution control technologies, recovery technologies, work practices, pollution prevention, monitoring, and/or changes in the manner of operation of the affected source. Use of back-up control techniques is not required, but is allowed, if available. * * * * *

   8. Section 63.1422 is amended by revising paragraph (b), by revising paragraph (e) introductory text, and removing and reserving paragraph (h) as follows:

      Sec. 63.1422 Compliance dates and relationship of this rule to existing applicable rules.

      * * * * *

      (b) New affected sources that commence construction or reconstruction after September 4, 1997 shall be in compliance with this subpart upon initial start-up or by June 1, 1999, whichever is later. * * * * *

      (e) Pursuant to section 112(i)(3)(B) of the Act, an owner or operator may request an extension allowing the existing affected source up to 1 additional year to comply with section 112(d) standards. For purposes of this subpart, a request for an extension shall be submitted to the permitting authority as part of the operating permit application, or to the Administrator as a separate submittal, or as part of the Precompliance Report. Requests for extensions shall be submitted no later than 120 days prior to the compliance dates specified in paragraphs (b) through (d) of this section, or as specified elsewhere in this subpart. The dates specified in Sec. 63.6(i) for submittal of requests for extensions shall not apply to this subpart. * * * * *

      (h) [Reserved]

   9. Section 63.1423 is amended by adding in alphabetical order the terms oil-water separator or organic-water separator and responsible official in paragraph (a) and by revising the definitions of epoxide, equipment leak, Group 2 wastewater stream, and polyether polyol in paragraph (b) as follows:

      Epoxide means a chemical compound consisting of a three-membered cyclic ether. Only emissions of epoxides listed in Table 4 of this subpart (i.e., ethylene oxide, propylene oxide, and epichlorohydrin) are regulated by the provisions of this subpart.

      Equipment leak means emissions of organic HAP from a connector, pump, compressor, agitator, pressure relief device, sampling connection system, open-ended valve or line, valve, surge control vessel, bottoms receiver, or instrumentation system in organic HAP service. * * * * *

      Group 2 wastewater stream means any process wastewater stream at an existing affected source or new affected source that does not meet the definition (in this section) of a Group 1 wastewater stream. * * * * *

      Polyether polyol means a compound formed through the polymerization of EO or PO or other cyclic ethers with compounds having one or more reactive hydrogens (i.e., a hydrogen atom bonded to nitrogen, oxygen, phosphorus, sulfur, etc.) to form polyethers (i.e., compounds with two or more ether bonds). This definition of polyether polyol excludes cellulose ethers (such as methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxy ethyl cellulose, and hydroxypropyl methyl cellulose) and materials regulated under 40 CFR part 63, subparts F, G, and H (the HON), such as glycols and glycol ethers. * * * * *
