Download as PDF 19266 Federal Register / Vol. 70, No. 70 / Wednesday, April 13, 2005 / Rules and Regulations 3. Section 199.15 is amended by revising paragraphs (b)(4)(i)(B) and (b)(4)(ii)(D) to read as follows: I § 199.15 Quality and utilization review peer review organization program. * * * * * (b) * * * (4) * * * (i) * * * (B) For healthcare services provided under TRICARE contracts entered into by the Department of Defense after October 30, 2000, medical necessity preauthorization will not be required for referrals for specialty consultation appointment services requested by primary care providers or specialty providers when referring TRICARE Prime beneficiaries for specialty consultation appointment services within the TRICARE contractor’s network. However, the lack of medical necessity preauthorization requirements for consultative appointment services does not mean that non-emergent admissions or invasive diagnostic or therapeutic procedures which in and of themselves constitute categories of health care services related to, but beyond the level of the consultation appointment service, are not subject to medical necessity prior authorization. In fact many such health care services may continue to require medical necessity prior authorization as determined by the Director, TRICARE Management Activity, or a designee. TRICARE Prime beneficiaries are also required to obtain preauthorization before seeking health care services from a non-network provider.

ACTION: Direct final rules; amendments. AGENCY: TRICARE program. * VerDate jul<14>2003 by the Department of Defense on or after October 30, 2000, referral requests (consultation requests) for specialty care consultation appointment services for TRICARE Prime beneficiaries must be submitted by primary care managers. Such referrals will be authorized by Health Care Finders (authorization numbers will be assigned so as to facilitate claims processing) but medical necessity preauthorization will not be required for referral consultation appointment services within the TRICARE contractor’s network. Some health care services subsequent to consultation appointments (invasive procedures, nonemergent admissions and other health care services as determined by the Director, TRICARE Management Activity, or a designee) will require medical necessity preauthorization. Though referrals for specialty care are generally the responsibility of the primary care managers, subject to discretion exercised by the TRICARE Regional Directors, and established in regional policy or memoranda of understanding, specialist providers may be permitted to refer patients for additional specialty consultation appointment services within the TRICARE contractor’s network without prior authorization by primary care managers or subject to medical necessity preauthorization. * * * * * Jkt 205001 SUMMARY: The EPA is taking direct final action on amendments to the National Emissions Standards for Hazardous Air PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 Pollutants for Source Categories: Generic Maximum Control Technology Standards which were promulgated in June 1999 (64 FR 34863), and the National Emission Standards for Ethylene Manufacturing Units: Heat Exchange Systems and Waste Operations which were promulgated in July 2002 (67 FR 46258). The direct final rule amendments clarify the compliance requirements for benzene waste streams, clarify the requirements for heat exchangers and heat exchanger systems, and stipulate the provisions for offsite waste transfer in the national emission standards for ethylene manufacturing process units. The direct final rule amendments also correct the regulatory language that make emissions from ethylene cracking furnaces during decoking operations an exception to the provisions and delineate overlapping requirements for storage vessels and transfer racks. In addition, the direct final rule amendments also correct errors in the proposed rule for the Acrylic and Modacrylic Fiber Production source category which were not corrected as indicated in the preamble to the June 1999 final rule (64 FR 34863). We are issuing the amendments as direct final rules, without prior proposal, because we view the revisions as noncontroversial and anticipate no adverse comments. However, in the Proposed Rules section of this Federal Register, we are publishing a separate document that will serve as the proposal to amend the National Emissions Standards for Hazardous Air Pollutants for Source Categories: Generic Maximum Control Technology Standards and the National Emission Standards for Ethylene Manufacturing Process Units: Heat Exchange Systems and Waste Operations. DATES: The direct final rule amendments are effective on June 13, 2005 without further notice, unless EPA receives adverse written comment by May 31, 2005. If adverse comments are received, EPA will publish a timely withdrawal in the Federal Register indicating which of the amendments will become effective, and which are being withdrawn due to adverse comment.

Moreover, under section 307(b)(2) of the CAA, the requirements established by the direct final rule amendments may not be challenged separately in any civil or criminal proceedings brought by the EPA to enforce these requirements. Outline. The following outline is provided to aid in reading the direct final rule amendments: I. Background II. Amendments to the NESHAP for Ethylene Manufacturing Process Units and the Generic MACT III. Rule Language Clarifications IV. Statutory and Executive Order Reviews A. Executive Order 12866, Regulatory Planning and Review B. Paper Reduction Act C. Regulatory Flexibility Act D. Unfunded Mandates Reform Act E. Executive Order 13132: Federalism F.

Executive Order 13211: Actions that Significantly Affect Energy Supply, Distribution or Use I. National Technology Transfer Advancement Act J. Congressional Review Act I. Background We are amending two rules. One rule is the National Emissions Standards for Hazardous Air Pollutants for Source Categories: Generic Maximum Control Technology Standards which were promulgated in June 1999 (64 FR 34863) and also referred to as the Generic Maximum Achievable Control Technology or ‘‘GMACT’’ rule, provide a structural framework that allows source categories with similar emission types and control requirements to be covered under common subparts; thus, promoting regulatory consistency in the development of national emission standards for hazardous air pollutants (NESHAP). The other rule is the National Emission Standards for Ethylene Manufacturing Process Units: Heat Exchange Systems and Waste Operations which were promulgated in July 2002 (67 FR 46258) in the same VerDate jul<14>2003 16:30 Apr 12, 2005 Jkt 205001 notice that added by amendment the Ethylene Production source category to the GMACT rule applicability. The amendments in today’s action clarify the compliance requirements for benzene waste streams, clarify the requirements for heat exchangers and heat exchanger systems, and stipulate the provisions for offsite waste transfer in the national emission standards for ethylene manufacturing process units (40 CFR part 63, subpart XX). The amendments in today’s action will also correct the regulatory language that make emissions from ethylene cracking furnaces during decoking operations an exception to the provisions, delineate overlapping requirements for storage vessels and transfer racks, and correct typographical errors in Table 7 to 40 CFR 63.1103(e), ‘‘What are my requirements if I own or operate an ethylene production existing or new affected source?’’ In addition, we are correcting errors to Table 3 to 40 CFR 63.1103(b)(3)(ii), ‘‘What are my requirements if I own or operate an acrylic and modacrylic fiber production existing or new affected source and am complying with paragraph (b)(3)(ii) of this section?’’ in the proposed rule for the Acrylic and Modacrylic Fiber Production source category which were not corrected as indicated in the preamble to the June 1999 final rule (64 FR 34863). II. Amendments to the NESHAP for Ethylene Manufacturing Process Units and the Generic MACT Today’s actions include amendments to the NESHAP for ethylene manufacturing process units to clarify compliance requirements for benzene waste streams, to clarify the requirements for heat exchangers and heat exchanger systems, and to stipulate the provisions for offsite waste transfer. We are also amending the generic MACT standards to correct the regulatory language to state that emissions from furnaces during decoking operations are an exception to the provisions, and we are delineating overlapping requirements for storage vessels and transfer racks. Another source in the generic MACT is acrylic and modacrylic fiber production for which we are amending the Compliance Requirements Table. We are amending 40 CFR 63.1086(b)(4) and 63.1095(a) to change units from parts per million by volume (ppmv) to parts per million by weight (ppmw) so that the units of measure accurately reflect the units of measure of the tests used by affected sources. We are amending 40 CFR 63.1086(a)(5) to clarify the PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 interpretation of the heat exchanger leak calculation requirements. While not explicitly stated, our intent in § 63.1086(a) was to define heat exchange systems in such a way as to ensure that leaks of 3.06 kilogram per hour (kg/hr) (the intended low end threshold of what would constitute a leak) or greater of hazardous air pollutants (HAP) into the cooling water stream are detectable and to specify that a leak is detected if the exit mean concentration is at least 10 percent greater than the entrance mean. We are amending 40 CFR 63.1086(a)(2)(ii)(B) and (b)(1)(ii) to include performance-based monitoring frequencies. We are amending 40 CFR 63.1095(b) to reword the type of waste stream to ‘‘waste streams that contain benzene,’’ which is consistent with the wording in 40 CFR 61.342(c). The change clarifies that this section specifically applies to ‘‘waste streams’’ containing benzene, not benzene containing streams in general, since there are product streams that also contain benzene. We are also amending 40 CFR 63.1095(b) to clarify an option for an owner or operator to transfer waste off-site to another facility for treatment, according to 40 CFR 63.1096. We are amending 40 CFR 63.1100(g)(1) to address overlapping storage vessel requirements in 40 CFR part 63, subpart YY, with the requirements in 40 CFR part 63, subparts G and CC. We are amending 40 CFR 63.1103(e)(1)(ii)(J) by removing the term ‘‘furnace stack,’’ because decoking emissions do not exit through the furnace stack. We are amending 40 CFR 63.1103(e)(2) to include a definition of ‘‘organic HAP’’ that identifies organic HAP as those compounds listed in Table 1 to 40 CFR part 63, subpart XX. We are amending 40 CFR 63.1103(g)(3) to clarify our intent that transfer racks at an ethylene affected source that are also subject to either 40 CFR part 63, subpart G, or 40 CFR part 61, subpart BB, are only required to comply with the requirements of 40 CFR part 63, subpart YY. III. Rule Language Clarifications Paragraphs (b) and (e) of 40 CFR 63.1084 contain provisions that exempt heat exchange systems that contain less than 5 percent HAP by weight in either an intervening fluid or process fluid. We have been asked to clarify the frequency intended for determining the HAP content for the purpose of establishing or maintaining the exempt status of a heat exchange system. The HAP content must be determined prior to claiming the exemption. Thereafter, the HAP E:\FR\FM\13APR1.SGM 13APR1 Federal Register / Vol. 70, No. 70 / Wednesday, April 13, 2005 / Rules and Regulations content must be determined whenever you are relying on the exemption and have reason to believe that the HAP content may be in excess of 5 percent. In general, if you make a process or operating change that would nullify the exemption and would, therefore, need to be identified as part of the affected source subject to 40 CFR part 63, subpart XX, you would make a determination shortly after the change is made and report the determination in the next semiannual report. Likewise, any determinations necessary to document continued exempt status following any process or operational changes that could affect the HAP content of the process fluid or intervening fluid should follow the same schedule. Along these same lines, if you do not make a process or operating change that could increase the HAP content of the process or intervening fluid, and you reasonably believe that the initial demonstration of exempt status is valid, you do not need to perform another determination. The periodic reporting requirements and schedule are specified in 40 CFR 63.1110(e) and (f). In response to stakeholder questions, we are clarifying that at facilities with total annual benzene (TAB) quantities less than the 10 megagrams per year (Mg/yr) (the applicability threshold of the Benzene Waste Operations NESHAP in 40 CFR part 61, subpart FF), the provisions of 40 CFR part 63, subpart XX, require control of two benzene waste streams as specified in § 63.1095(b)(1), and require control of continuous butadiene waste streams meeting the concentration and flow rate criteria at any benzene level (under 40 CFR 63.1095(a)(3)). Section 63.1095(b)(1) requires facilities whose TAB quantity from waste is less than 10 Mg/yr to manage and treat the two named benzene waste streams—spent caustic waste streams and dilution steam blowdown waste streams— according to 40 CFR 61.342(c)(1) through (c)(3)(i). Facilities with a TAB quantity from waste of 10 Mg/yr or greater must comply with the requirements of 40 CFR 63.1095(b)(2). These requirements are explained in the July 12, 2002, preamble to the final rule (67 FR 46265). Section 112 of the CAA requires standards for control of HAP, not only benzene; hence, all facilities subject to the Ethylene Production NESHAP (regardless of TAB quantity) are required to control continuous butadiene waste streams, as required in 40 CFR 63.1095(a). We are clarifying the intent of provisions regarding overlapping provisions for leak detection and repair VerDate jul<14>2003 16:30 Apr 12, 2005 Jkt 205001 requirements for ethylene manufacturing process units (EMPU) as established by 40 CFR part 63, subpart UU. Equipment within an EMPU may potentially be regulated by several other equipment leak regulations, such as 40 CFR part 61, subparts J and V; 40 CFR part 60, subpart VV; and 40 CFR part 63, subpart H. To address this overlap, the regulations provide that in cases where 40 CFR part 63, subpart UU, overlaps the other requirements, the equipment need only comply with the subpart UU requirements, since subpart UU is at least as stringent as the overlapping regulations. For ease in compliance, we understand that some affected sources may wish to comply with subpart UU requirements for equipment leaks for the entire EMPU, even for equipment not in HAP service. In these cases, the owner or operator should specify the use of 40 CFR part 63, subpart UU, for the entire EMPU in the Notification of Compliance Status report required by 40 CFR 63.1110(a)(4). We are clarifying the intent of the exclusions contained in 40 CFR 63.1100(e)(1)(iii) and how they relate to the overlap requirements. For process units that are currently regulated under other subparts of 40 CFR part 63, § 63.1100(g) provides provisions when applicability of 40 CFR part 63, subpart YY, and other subparts of 40 CFR parts 60, 61 and 63 overlap, allowing sources to elect which subpart to comply with in some cases. In respect to facilities that produce ethylene, these exclusions and overlap provisions were intended for facilities that have collocated process units currently subject to other 40 CFR part 63 subparts in addition to their ethylene production units. For example, a facility could have a refinery subject to 40 CFR part 63, subpart CC (Petroleum Refinery NESHAP), in addition to an ethylene production unit, and within the refinery operations there is equipment that separates propylene from the refinery gas stream, but the product propylene is not intended for, or used in, ethylene production. The equipment in question, while performing a function that is common to ethylene manufacturing, is already regulated under the Petroleum Refinery NESHAP (40 CFR part 63, subpart CC) and may be excluded from the Ethylene Production NESHAP (40 CFR part 63, subpart YY) applicability on that basis. Our overall intent is to avoid duplication and confusion in monitoring, recordkeeping and reporting requirements by requiring that process equipment that is potentially subject to more than one 40 CFR part 63 subpart must be in compliance with one PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 19269 subpart, but (pursuant to these exclusion and overlap provisions) need not comply with multiple subparts. These provisions and exclusions do not authorize noncompliance with any of the 40 CFR part 63 requirements for a source that would otherwise be subject to one or more 40 CFR part 63 subparts. We are clarifying that small containers, portable bins and portable tanks are not included in the definition of ‘‘storage vessel or tank’’ found in 40 CFR 63.1101 since the definition applies to ‘‘* * * a stationary unit * * *.’’ It was not our intent to regulate the small containers, portable bins and portable tanks, and we believe that by distinguishing that the vessels must be stationary is adequate for determining regulated vessels. Section 63.1105(h)(1) of 40 CFR part 63 requires ‘‘the pressure test procedures specified in Method 27 of appendix A to 40 CFR part 60’’ to test for vapor tightness. Vapor tight, as defined in 40 CFR 63.1105(d)(2), means that the pressure in the tank will not drop more than 750 pascals within 5 minutes after it is pressurized to a minimum of 4,500 pascals. This regulatory wording clearly requires you to test for vapor tightness using the pressure test procedures described in Method 27 and does not require a vacuum test. We confirm that it is our intent to require only pressure testing. The appropriate pressure test is described in 40 CFR part 60, appendix A, section 8.2.2 of Method 27, and the vacuum test described in section 8.2.3 of Method 27 is not required. IV. Statutory and Executive Order Reviews A. Executive Order 12866, Regulatory Planning and Review Under Executive Order 12866 (58 FR 51735, October 4, 1993), we must determine whether the regulatory action is ‘‘significant’’ and, therefore, subject to review by the Office of Management and Budget (OMB) 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, a sector of 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; E:\FR\FM\13APR1.SGM 13APR1 19270 Federal Register / Vol. 70, No. 70 / Wednesday, April 13, 2005 / Rules and Regulations (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. It has been determined that the direct final rule amendments are not a ‘‘significant regulatory action’’ under the terms of Executive Order 12866 and, therefore, are not subject to review by OMB. B. Paperwork Reduction Act This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The direct final rule amendments result in no changes to the information collection requirements of the standards or guidelines and will have no impact on the information collection estimate of project cost and hour burden made at the time these rule were promulgated. Therefore, the information collection requests have not been revised. The OMB has previously approved the information collection requirements contained in 40 CFR part 63, subpart YY under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq, and assigned OMB control number 2060–0420 (EPA ICR 1871.02) for Acrylic and Modacrylic Fiber Production, and OMB control number 2060–0489 for Ethylene Production (EPA ICR 1983.02). Copies of the Information Collection Request (ICR) document(s) may be obtained from Susan Auby by mail at U.S. EPA, Office of Environmental Information, Collection Strategies Division (2822T), 1200 Pennsylvania Avenue, NW., Washington, DC 20460, by e-mail at auby.susan@epa.gov, or by calling (202) 566–1672. A copy may also be downloaded off the Internet at https://www.epa.gov/icr. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of VerDate jul<14>2003 16:30 Apr 12, 2005 Jkt 205001 information; and transmit or otherwise disclose the information. An agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in 40 CFR are listed in 40 CFR part 9. C. Regulatory Flexibility Act EPA has determined that it is not necessary to prepare a regulatory flexibility analysis in connection with the direct final rule amendments. For purposes of assessing the impacts of today’s direct final rule amendments on small entities, a small entity is defined as: (1) A small business in the North American Industrial Classification System (NAICS) code 325 that has up to 500; (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 today’s direct final rule amendments on small entities, we have concluded that this action will not have a significant economic impact on a substantial number of small entities. The direct final rule amendments will not impose any requirements on small entities. The direct final rule amendments provide clarifications and corrections to previously issued rules. Before promulgating the rule on acrylic and modacrylic fiber production in 1999 (64 FR 34863), we concluded that each standard applied to five or fewer major sources. In addition, we conducted a limited assessment of the economic effect of the proposed standards on small entities that showed no adverse economic effect for any small entities within any of these source categories. Similarly, before promulgating the rules on ethylene production in 2002 (67 FR 46258), we determined that there were no small entities affected by those rules. D. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act (UMRA) of 1995, Public Law 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, we generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with ‘‘Federal mandates’’ that may result in expenditures by State, local, PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 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 us to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most costeffective, 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 us to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if we publish with the final rule an explanation why that alternative was not adopted. Before we establish any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, we must develop a small government agency plan under section 203 of the UMRA. 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 our regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements. We have determined that the direct final rule amendments 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 the private sector in any 1 year. Thus, the direct final rule amendments are not subject to the requirements of section 202 and 205 of the UMRA. In addition, we have determined that the direct final rule amendments contain no regulatory requirements that might significantly or uniquely affect small governments because they contain no requirements that apply to small governments or impose obligations on them. E. Executive Order 13132: Federalism Executive Order 13132 (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 E:\FR\FM\13APR1.SGM 13APR1 Federal Register / Vol. 70, No. 70 / Wednesday, April 13, 2005 / Rules and Regulations responsibilities among the various levels of government.’’ The direct final rule amendments do not have federalism implications. They 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. The direct final rule amendments will not impose substantial direct compliance costs on State or local governments and will not preempt State law. Thus, Executive Order 13132 does not apply to the direct final rule amendments. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Executive Order 13175 (65 FR 67249, November 9, 2000) requires us to develop an accountable process to ensure ‘‘meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.’’ The direct final rule amendments do not have tribal implications, as specified in Executive Order 13175. They will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to the direct final rule amendments. G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks 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 we have reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, we 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 we considered. 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 Executive Order has the potential to influence the regulation. The direct final rule amendments are not subject to Executive Order 13045 because they are VerDate jul<14>2003 17:44 Apr 12, 2005 Jkt 205001 based on technology performance and not on health and safety risks. Also, the direct final rule amendments are not ‘‘economically significant.’’ H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution or Use The direct final rule amendments are not subject to Executive Order 13211 (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866. I. National Technology Transfer Advancement Act (NTTAA) Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104– 113, 12(d)(15 U.S.C. 272 note) directs us to use voluntary consensus standards in our regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., material specifications, test methods, sampling procedures, and business practices) developed or adopted by one or more voluntary consensus bodies. The NTTAA directs us to provide Congress, through OMB, explanations when we decide not to use available and applicable voluntary consensus standards. The direct final rule amendments do not involve modifications to the technical standards specified in the final rules for Acrylic and Modacrylic Fiber Production and Ethylene Production. Therefore, we did not consider the use of any voluntary consensus standards. J. Congressional Review Act The Congressional Review Act, 5 U.S.C. 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 Congress and to the Comptroller General of the United States. We will submit a report containing the direct final 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 direct final rule amendments in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. These direct final rule amendments are not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

ACTION: Direct final rule. AGENCY: SUMMARY: The Environmental Protection Agency (EPA) is promulgating this direct final rule to correct the final rule published in the Federal Register on March 12, 2004. Specifically, EPA is amending the regulatory text for the definitions of refrigerant and technician. EPA is also amending the prohibition against venting substitute refrigerants to reflect the changes in the definitions. These changes are being finalized to make certain that the regulations promulgated on March 12, 2004 cannot be construed as a restriction on the sales of substitutes that do not consist of an ozone-depleting substance (ODS), such as pure hydrofluorocarbon (HFC) and perfluorocarbon (PFC) substitutes. DATES: This direct rule is effective on June 13, 2005, without further notice, unless EPA receives adverse comment by May 13, 2005. If EPA receives adverse comment, the Agency will publish a timely withdrawal in the Federal Register informing the public that this rule will not take effect.

National Emission Standards for Hazardous Air Pollutants for 
Source Categories: Generic Maximum Achievable Control Technology 
Standards; and National Emission Standards for Ethylene Manufacturing 
Process Units: Heat Exchange Systems and Waste Operations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rules; amendments.

-----------------------------------------------------------------------

SUMMARY: The EPA is taking direct final action on amendments to the 
National Emissions Standards for Hazardous Air Pollutants for Source 
Categories: Generic Maximum Control Technology Standards which were 
promulgated in June 1999 (64 FR 34863), and the National Emission 
Standards for Ethylene Manufacturing Units: Heat Exchange Systems and 
Waste Operations which were promulgated in July 2002 (67 FR 46258). The 
direct final rule amendments clarify the compliance requirements for 
benzene waste streams, clarify the requirements for heat exchangers and 
heat exchanger systems, and stipulate the provisions for offsite waste 
transfer in the national emission standards for ethylene manufacturing 
process units. The direct final rule amendments also correct the 
regulatory language that make emissions from ethylene cracking furnaces 
during decoking operations an exception to the provisions and delineate 
overlapping requirements for storage vessels and transfer racks.
    In addition, the direct final rule amendments also correct errors 
in the proposed rule for the Acrylic and Modacrylic Fiber Production 
source category which were not corrected as indicated in the preamble 
to the June 1999 final rule (64 FR 34863).
    We are issuing the amendments as direct final rules, without prior 
proposal, because we view the revisions as noncontroversial and 
anticipate no adverse comments. However, in the Proposed Rules section 
of this Federal Register, we are publishing a separate document that 
will serve as the proposal to amend the National Emissions Standards 
for Hazardous Air Pollutants for Source Categories: Generic Maximum 
Control Technology Standards and the National Emission Standards for 
Ethylene Manufacturing Process Units: Heat Exchange Systems and Waste 
Operations.

DATES: The direct final rule amendments are effective on June 13, 2005 
without further notice, unless EPA receives adverse written comment by 
May 31, 2005. If adverse comments are received, EPA will publish a 
timely withdrawal in the Federal Register indicating which of the 
amendments will become effective, and which are being withdrawn due to 
adverse comment.

the Proposed Rules section of today's Federal Register, we are 
publishing a separate document that will serve as the proposal to the 
amendments in the rules if adverse comments are filed. If we receive 
any adverse comments on one or more distinct amendments, we will 
publish a timely withdrawal in the Federal Register informing the 
public which amendments will become effective and which amendments are 
being withdrawn due to adverse comments. We will address all public 
comments in subsequent final rules based on the proposed rules. Any of 
the distinct amendments in today's final rules for which we do not 
receive adverse comment will become effective on the previously 
mentioned date. We will not institute a second comment period on

[[Page 19268]]

this action. Any parties interested in commenting must do so at this 
time.
    Judicial Review. Under section 307(b)(1) of the CAA, judicial 
review of these direct final rules is available only by filing a 
petition for review in the U.S. Court of Appeals for the District of 
Columbia Circuit by June 13, 2005. Under section 307(d)(7)(B) of the 
CAA, only an objection to the direct final rule amendments that was 
raised with reasonable specificity during the period for public comment 
can be raised during judicial review. Moreover, under section 307(b)(2) 
of the CAA, the requirements established by the direct final rule 
amendments may not be challenged separately in any civil or criminal 
proceedings brought by the EPA to enforce these requirements.

    J. Congressional Review Act

I. Background

    We are amending two rules. One rule is the National Emissions 
Standards for Hazardous Air Pollutants for Source Categories: Generic 
Maximum Control Technology Standards which were promulgated in June 
1999 (64 FR 34863) and also referred to as the Generic Maximum 
Achievable Control Technology or ``GMACT'' rule, provide a structural 
framework that allows source categories with similar emission types and 
control requirements to be covered under common subparts; thus, 
promoting regulatory consistency in the development of national 
emission standards for hazardous air pollutants (NESHAP). The other 
rule is the National Emission Standards for Ethylene Manufacturing 
Process Units: Heat Exchange Systems and Waste Operations which were 
promulgated in July 2002 (67 FR 46258) in the same notice that added by 
amendment the Ethylene Production source category to the GMACT rule 
applicability.
    The amendments in today's action clarify the compliance 
requirements for benzene waste streams, clarify the requirements for 
heat exchangers and heat exchanger systems, and stipulate the 
provisions for offsite waste transfer in the national emission 
standards for ethylene manufacturing process units (40 CFR part 63, 
subpart XX).
    The amendments in today's action will also correct the regulatory 
language that make emissions from ethylene cracking furnaces during 
decoking operations an exception to the provisions, delineate 
overlapping requirements for storage vessels and transfer racks, and 
correct typographical errors in Table 7 to 40 CFR 63.1103(e), ``What 
are my requirements if I own or operate an ethylene production existing 
or new affected source?''
    In addition, we are correcting errors to Table 3 to 40 CFR 
63.1103(b)(3)(ii), ``What are my requirements if I own or operate an 
acrylic and modacrylic fiber production existing or new affected source 
and am complying with paragraph (b)(3)(ii) of this section?'' in the 
proposed rule for the Acrylic and Modacrylic Fiber Production source 
category which were not corrected as indicated in the preamble to the 
June 1999 final rule (64 FR 34863).

II. Amendments to the NESHAP for Ethylene Manufacturing Process Units 
and the Generic MACT

    Today's actions include amendments to the NESHAP for ethylene 
manufacturing process units to clarify compliance requirements for 
benzene waste streams, to clarify the requirements for heat exchangers 
and heat exchanger systems, and to stipulate the provisions for offsite 
waste transfer. We are also amending the generic MACT standards to 
correct the regulatory language to state that emissions from furnaces 
during decoking operations are an exception to the provisions, and we 
are delineating overlapping requirements for storage vessels and 
transfer racks. Another source in the generic MACT is acrylic and 
modacrylic fiber production for which we are amending the Compliance 
Requirements Table.
    We are amending 40 CFR 63.1086(b)(4) and 63.1095(a) to change units 
from parts per million by volume (ppmv) to parts per million by weight 
(ppmw) so that the units of measure accurately reflect the units of 
measure of the tests used by affected sources.
    We are amending 40 CFR 63.1086(a)(5) to clarify the interpretation 
of the heat exchanger leak calculation requirements. While not 
explicitly stated, our intent in Sec.  63.1086(a) was to define heat 
exchange systems in such a way as to ensure that leaks of 3.06 kilogram 
per hour (kg/hr) (the intended low end threshold of what would 
constitute a leak) or greater of hazardous air pollutants (HAP) into 
the cooling water stream are detectable and to specify that a leak is 
detected if the exit mean concentration is at least 10 percent greater 
than the entrance mean.
    We are amending 40 CFR 63.1086(a)(2)(ii)(B) and (b)(1)(ii) to 
include performance-based monitoring frequencies.
    We are amending 40 CFR 63.1095(b) to reword the type of waste 
stream to ``waste streams that contain benzene,'' which is consistent 
with the wording in 40 CFR 61.342(c). The change clarifies that this 
section specifically applies to ``waste streams'' containing benzene, 
not benzene containing streams in general, since there are product 
streams that also contain benzene. We are also amending 40 CFR 
63.1095(b) to clarify an option for an owner or operator to transfer 
waste off-site to another facility for treatment, according to 40 CFR 
63.1096.
    We are amending 40 CFR 63.1100(g)(1) to address overlapping storage 
vessel requirements in 40 CFR part 63, subpart YY, with the 
requirements in 40 CFR part 63, subparts G and CC.
    We are amending 40 CFR 63.1103(e)(1)(ii)(J) by removing the term 
``furnace stack,'' because decoking emissions do not exit through the 
furnace stack. We are amending 40 CFR 63.1103(e)(2) to include a 
definition of ``organic HAP'' that identifies organic HAP as those 
compounds listed in Table 1 to 40 CFR part 63, subpart XX.
    We are amending 40 CFR 63.1103(g)(3) to clarify our intent that 
transfer racks at an ethylene affected source that are also subject to 
either 40 CFR part 63, subpart G, or 40 CFR part 61, subpart BB, are 
only required to comply with the requirements of 40 CFR part 63, 
subpart YY.

III. Rule Language Clarifications

    Paragraphs (b) and (e) of 40 CFR 63.1084 contain provisions that 
exempt heat exchange systems that contain less than 5 percent HAP by 
weight in either an intervening fluid or process fluid. We have been 
asked to clarify the frequency intended for determining the HAP content 
for the purpose of establishing or maintaining the exempt status of a 
heat exchange system. The HAP content must be determined prior to 
claiming the exemption. Thereafter, the HAP

[[Page 19269]]

content must be determined whenever you are relying on the exemption 
and have reason to believe that the HAP content may be in excess of 5 
percent. In general, if you make a process or operating change that 
would nullify the exemption and would, therefore, need to be identified 
as part of the affected source subject to 40 CFR part 63, subpart XX, 
you would make a determination shortly after the change is made and 
report the determination in the next semiannual report. Likewise, any 
determinations necessary to document continued exempt status following 
any process or operational changes that could affect the HAP content of 
the process fluid or intervening fluid should follow the same schedule. 
Along these same lines, if you do not make a process or operating 
change that could increase the HAP content of the process or 
intervening fluid, and you reasonably believe that the initial 
demonstration of exempt status is valid, you do not need to perform 
another determination. The periodic reporting requirements and schedule 
are specified in 40 CFR 63.1110(e) and (f).
    In response to stakeholder questions, we are clarifying that at 
facilities with total annual benzene (TAB) quantities less than the 10 
megagrams per year (Mg/yr) (the applicability threshold of the Benzene 
Waste Operations NESHAP in 40 CFR part 61, subpart FF), the provisions 
of 40 CFR part 63, subpart XX, require control of two benzene waste 
streams as specified in Sec.  63.1095(b)(1), and require control of 
continuous butadiene waste streams meeting the concentration and flow 
rate criteria at any benzene level (under 40 CFR 63.1095(a)(3)). 
Section 63.1095(b)(1) requires facilities whose TAB quantity from waste 
is less than 10 Mg/yr to manage and treat the two named benzene waste 
streams--spent caustic waste streams and dilution steam blowdown waste 
streams--according to 40 CFR 61.342(c)(1) through (c)(3)(i). Facilities 
with a TAB quantity from waste of 10 Mg/yr or greater must comply with 
the requirements of 40 CFR 63.1095(b)(2). These requirements are 
explained in the July 12, 2002, preamble to the final rule (67 FR 
46265). Section 112 of the CAA requires standards for control of HAP, 
not only benzene; hence, all facilities subject to the Ethylene 
Production NESHAP (regardless of TAB quantity) are required to control 
continuous butadiene waste streams, as required in 40 CFR 63.1095(a).
    We are clarifying the intent of provisions regarding overlapping 
provisions for leak detection and repair requirements for ethylene 
manufacturing process units (EMPU) as established by 40 CFR part 63, 
subpart UU. Equipment within an EMPU may potentially be regulated by 
several other equipment leak regulations, such as 40 CFR part 61, 
subparts J and V; 40 CFR part 60, subpart VV; and 40 CFR part 63, 
subpart H. To address this overlap, the regulations provide that in 
cases where 40 CFR part 63, subpart UU, overlaps the other 
requirements, the equipment need only comply with the subpart UU 
requirements, since subpart UU is at least as stringent as the 
overlapping regulations. For ease in compliance, we understand that 
some affected sources may wish to comply with subpart UU requirements 
for equipment leaks for the entire EMPU, even for equipment not in HAP 
service. In these cases, the owner or operator should specify the use 
of 40 CFR part 63, subpart UU, for the entire EMPU in the Notification 
of Compliance Status report required by 40 CFR 63.1110(a)(4).
    We are clarifying the intent of the exclusions contained in 40 CFR 
63.1100(e)(1)(iii) and how they relate to the overlap requirements. For 
process units that are currently regulated under other subparts of 40 
CFR part 63, Sec.  63.1100(g) provides provisions when applicability of 
40 CFR part 63, subpart YY, and other subparts of 40 CFR parts 60, 61 
and 63 overlap, allowing sources to elect which subpart to comply with 
in some cases. In respect to facilities that produce ethylene, these 
exclusions and overlap provisions were intended for facilities that 
have collocated process units currently subject to other 40 CFR part 63 
subparts in addition to their ethylene production units. For example, a 
facility could have a refinery subject to 40 CFR part 63, subpart CC 
(Petroleum Refinery NESHAP), in addition to an ethylene production 
unit, and within the refinery operations there is equipment that 
separates propylene from the refinery gas stream, but the product 
propylene is not intended for, or used in, ethylene production. The 
equipment in question, while performing a function that is common to 
ethylene manufacturing, is already regulated under the Petroleum 
Refinery NESHAP (40 CFR part 63, subpart CC) and may be excluded from 
the Ethylene Production NESHAP (40 CFR part 63, subpart YY) 
applicability on that basis. Our overall intent is to avoid duplication 
and confusion in monitoring, recordkeeping and reporting requirements 
by requiring that process equipment that is potentially subject to more 
than one 40 CFR part 63 subpart must be in compliance with one subpart, 
but (pursuant to these exclusion and overlap provisions) need not 
comply with multiple subparts. These provisions and exclusions do not 
authorize noncompliance with any of the 40 CFR part 63 requirements for 
a source that would otherwise be subject to one or more 40 CFR part 63 
subparts.
    We are clarifying that small containers, portable bins and portable 
tanks are not included in the definition of ``storage vessel or tank'' 
found in 40 CFR 63.1101 since the definition applies to ``* * * a 
stationary unit * * *.'' It was not our intent to regulate the small 
containers, portable bins and portable tanks, and we believe that by 
distinguishing that the vessels must be stationary is adequate for 
determining regulated vessels.
    Section 63.1105(h)(1) of 40 CFR part 63 requires ``the pressure 
test procedures specified in Method 27 of appendix A to 40 CFR part 
60'' to test for vapor tightness. Vapor tight, as defined in 40 CFR 
63.1105(d)(2), means that the pressure in the tank will not drop more 
than 750 pascals within 5 minutes after it is pressurized to a minimum 
of 4,500 pascals. This regulatory wording clearly requires you to test 
for vapor tightness using the pressure test procedures described in 
Method 27 and does not require a vacuum test. We confirm that it is our 
intent to require only pressure testing. The appropriate pressure test 
is described in 40 CFR part 60, appendix A, section 8.2.2 of Method 27, 
and the vacuum test described in section 8.2.3 of Method 27 is not 
required.

IV. Statutory and Executive Order Reviews

A. Executive Order 12866, Regulatory Planning and Review

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), we must 
determine whether the regulatory action is ``significant'' and, 
therefore, subject to review by the Office of Management and Budget 
(OMB) 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, a sector of 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;

[[Page 19270]]

    (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.
    It has been determined that the direct final rule amendments are 
not a ``significant regulatory action'' under the terms of Executive 
Order 12866 and, therefore, are not subject to review by OMB.

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 
The direct final rule amendments result in no changes to the 
information collection requirements of the standards or guidelines and 
will have no impact on the information collection estimate of project 
cost and hour burden made at the time these rule were promulgated. 
Therefore, the information collection requests have not been revised. 
The OMB has previously approved the information collection requirements 
contained in 40 CFR part 63, subpart YY under the provisions of the 
Paperwork Reduction Act, 44 U.S.C. 3501 et seq, and assigned OMB 
control number 2060-0420 (EPA ICR 1871.02) for Acrylic and Modacrylic 
Fiber Production, and OMB control number 2060-0489 for Ethylene 
Production (EPA ICR 1983.02).
    Copies of the Information Collection Request (ICR) document(s) may 
be obtained from Susan Auby by mail at U.S. EPA, Office of 
Environmental Information, Collection Strategies Division (2822T), 1200 
Pennsylvania Avenue, NW., Washington, DC 20460, by e-mail at 
auby.susan@epa.gov, or by calling (202) 566-1672. A copy may also be 
downloaded off the Internet at https://www.epa.gov/icr.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, disclose or provide 
information to or for a Federal agency. This includes the time needed 
to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    An agency may not conduct or sponsor and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    EPA has determined that it is not necessary to prepare a regulatory 
flexibility analysis in connection with the direct final rule 
amendments. For purposes of assessing the impacts of today's direct 
final rule amendments on small entities, a small entity is defined as: 
(1) A small business in the North American Industrial Classification 
System (NAICS) code 325 that has up to 500; (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 today's direct final rule 
amendments on small entities, we have concluded that this action will 
not have a significant economic impact on a substantial number of small 
entities. The direct final rule amendments will not impose any 
requirements on small entities. The direct final rule amendments 
provide clarifications and corrections to previously issued rules. 
Before promulgating the rule on acrylic and modacrylic fiber production 
in 1999 (64 FR 34863), we concluded that each standard applied to five 
or fewer major sources. In addition, we conducted a limited assessment 
of the economic effect of the proposed standards on small entities that 
showed no adverse economic effect for any small entities within any of 
these source categories. Similarly, before promulgating the rules on 
ethylene production in 2002 (67 FR 46258), we determined that there 
were no small entities affected by those rules.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act (UMRA) of 1995, Public 
Law 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, we 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures by 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 us 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 us to adopt an alternative other than the least 
costly, most cost-effective, or least burdensome alternative if we 
publish with the final rule an explanation why that alternative was not 
adopted.
    Before we establish any regulatory requirements that may 
significantly or uniquely affect small governments, including tribal 
governments, we must develop a small government agency plan under 
section 203 of the UMRA. 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 our regulatory proposals with significant Federal 
intergovernmental mandates, and informing, educating, and advising 
small governments on compliance with the regulatory requirements.
    We have determined that the direct final rule amendments 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 the private sector in any 1 year. Thus, the direct final 
rule amendments are not subject to the requirements of section 202 and 
205 of the UMRA. In addition, we have determined that the direct final 
rule amendments contain no regulatory requirements that might 
significantly or uniquely affect small governments because they contain 
no requirements that apply to small governments or impose obligations 
on them.

E. Executive Order 13132: Federalism

    Executive Order 13132 (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

[[Page 19271]]

responsibilities among the various levels of government.''
    The direct final rule amendments do not have federalism 
implications. They 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. 
The direct final rule amendments will not impose substantial direct 
compliance costs on State or local governments and will not preempt 
State law. Thus, Executive Order 13132 does not apply to the direct 
final rule amendments.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175 (65 FR 67249, November 9, 2000) requires us 
to develop an accountable process to ensure ``meaningful and timely 
input by tribal officials in the development of regulatory policies 
that have tribal implications.''
    The direct final rule amendments do not have tribal implications, 
as specified in Executive Order 13175. They will not have substantial 
direct effects on tribal governments, on the relationship between the 
Federal government and Indian tribes, or on the distribution of power 
and responsibilities between the Federal government and Indian tribes, 
as specified in Executive Order 13175. Thus, Executive Order 13175 does 
not apply to the direct final rule amendments.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    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 we have reason to believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, we 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 we considered.
    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 Executive Order has 
the potential to influence the regulation. The direct final rule 
amendments are not subject to Executive Order 13045 because they are 
based on technology performance and not on health and safety risks. 
Also, the direct final rule amendments are not ``economically 
significant.''

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution or Use

    The direct final rule amendments are not subject to Executive Order 
13211 (66 FR 28355, May 22, 2001) because it is not a significant 
regulatory action under Executive Order 12866.

I. National Technology Transfer Advancement Act (NTTAA)

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTAA), Public Law 104-113, 12(d)(15 U.S.C. 272 note) 
directs us to use voluntary consensus standards in our regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., material specifications, test methods, sampling 
procedures, and business practices) developed or adopted by one or more 
voluntary consensus bodies. The NTTAA directs us to provide Congress, 
through OMB, explanations when we decide not to use available and 
applicable voluntary consensus standards.
    The direct final rule amendments do not involve modifications to 
the technical standards specified in the final rules for Acrylic and 
Modacrylic Fiber Production and Ethylene Production. Therefore, we did 
not consider the use of any voluntary consensus standards.

J. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 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 Congress and to the Comptroller General of the United 
States. We will submit a report containing the direct final 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 direct final rule amendments in the Federal 
Register. A major rule cannot take effect until 60 days after it is 
published in the Federal Register. These direct final rule amendments 
are not a ``major rule'' as defined by 5 U.S.C. 804(2).

* * * * *
    (a) * * *
    (2) * * *
    (ii) Monitor weekly for 6 months, both initially and following 
completion of a leak repair. Then monitor as provided in paragraph 
(a)(2)(ii)(A) or (B) of this section, as appropriate.
    (A) If no leaks are detected by monitoring weekly for a 6-month 
period, monitor monthly thereafter until a leak is detected.

* * * * *
    (5) Calculate the average entrance and exit concentrations, 
correcting for the addition of make-up water and evaporative losses, if 
applicable. Using a one-sided statistical procedure at the 0.05 level 
of significance, if the exit mean concentration is at least 10 percent 
greater than the entrance mean of the HAP (total or speciated) in Table 
1 to this subpart or other representative substance, and the leak is at 
least 3.06 kg/hr, you have detected a leak.
    (b) * * *

    (4) Calculate the average entrance and exit concentrations, 
correcting for the addition of make-up water and evaporative losses, if 
applicable. Using a one-sided statistical procedure at the 0.05 level 
of significance, if the exit mean concentration is at least 1 ppmw or 
10 percent greater than the entrance mean, whichever is greater, you 
have detected a leak.
