ACTION: Proposed rule. AGENCY: EPA is proposing to partially approve and partially disapprove the State Implementation Plan (SIP) submission from the State of Wyoming to demonstrate that the SIP meets the requirements of Sections 110(a)(1) and (2) of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for ozone on July 18, 1997. Section 110(a)(1) of the CAA requires that each state, after a new or revised NAAQS is promulgated, review their SIPs to ensure that they meet the requirements of the ‘‘infrastructure elements’’ of section 110(a)(2). The State of Wyoming submitted two certifications of their infrastructure SIP for the 1997 ozone NAAQS, date December 7, 2007 and December 10, 2009. EPA does not propose to act on the State’s May 25, 2007 submission to meet the requirements of section 110(a)(2)(D)(i) of the CAA, relating to interstate transport of air pollution, for the 1997 ozone NAAQS. EPA approved the State’s interstate transport SIP submission on May 8, 2008 (73 FR 26019).

II. Background On July 18, 1997, EPA promulgated new NAAQS for ozone based on 8-hour average concentrations. The 8-hour averaging period replaced the previous 1-hour averaging period, and the level of the NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm (62 FR 38856). By statute, SIPs meeting the requirements of sections 110(a)(1) and (2) are to be submitted by states within three years after promulgation of a new or revised standard. Section 110(a)(2) provides basic requirements for SIPs, including emissions inventories, monitoring, and modeling, to assure attainment and maintenance of the VerDate Mar<15>2010 16:40 May 20, 2011 Jkt 223001 standards. These requirements are set out in several ‘‘infrastructure elements,’’ listed in section 110(a)(2). Section 110(a) imposes the obligation upon states to make a SIP submission to EPA for a new or revised NAAQS, and the contents of that submission may vary depending upon the facts and circumstances. In particular, the data and analytical tools available at the time the state develops and submits the SIP for a new or revised NAAQS affects the content of the submission. The contents of such SIP submissions may also vary depending upon what provisions the state’s existing SIP already contains. In the case of the 1997 ozone NAAQS, states typically have met the basic program elements required in section 110(a)(2) through earlier SIP submissions in connection with previous NAAQS. In a guidance issued on October 2, 2007, EPA noted that, to the extent an existing SIP already meets the section 110(a)(2) requirements, states need only to certify that fact via a letter to EPA.1 On March 27, 2008, EPA published a final rule entitled, ‘‘Completeness Findings for Section 110(a) State Implementation Plans for the 8-hour Ozone NAAQS’’ (73 FR 16205). In the rule, EPA made a finding for each State that it had submitted or had failed to submit a complete SIP that provided the basic program elements of section 110(a)(2) necessary to implement the 1997 8-hour ozone NAAQS. In particular, EPA found that Wyoming had submitted a complete SIP to meet these requirements. III. What infrastructure elements are required under sections 110(a)(1) and (2)? Section 110(a)(1) provides the procedural and timing requirements for SIP submissions after a new or revised NAAQS is promulgated. Section 110(a)(2) lists specific elements the SIP must contain or satisfy. These infrastructure elements include requirements, such as modeling, monitoring, and emissions inventories that are designed to assure attainment and maintenance of the NAAQS. The elements that are the subject of this action are listed below. • 110(a)(2)(A): Emission limits and other control measures. • 110(a)(2)(B): Ambient air quality monitoring/data system. 1 Memorandum from William T. Harnett, Director, Air Quality Policy Division, ‘‘Guidance on SIP Elements Required Under Sections 110(a)(1) and (2) for the 1997 8-hour Ozone and PM2.5 National Ambient Air Quality Standards’’ (Oct. 2, 2007). PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 29681 • 110(a)(2)(C): Program for enforcement of control measures. • 110(a)(2)(D)(ii): Interstate and international pollution. • 110(a)(2)(E): Adequate resources and authority. • 110(a)(2)(F): Stationary source monitoring and reporting. • 110(a)(2)(G): Emergency powers. • 110(a)(2)(H): Future SIP revisions. • 110(a)(2)(J): Consultation with government officials; public notification; and prevention of significant deterioration (PSD) and visibility protection. • 110(a)(2)(K): Air quality modeling/ data. • 110(a)(2)(L): Permitting fees. • 110(a)(2)(M): Consultation/ participation by affected local entities. A detailed discussion of each of these elements is contained in the next section. Two elements identified in section 110(a)(2) are not governed by the threeyear submission deadline of section 110(a)(1) and are therefore not addressed in this action. These elements relate to part D of Title I of the CAA, and submissions to satisfy them are not due within three years after promulgation of a new or revised NAAQS, but rather are due at the same time nonattainment area plan requirements are due under section 172. The two elements are: (i) section 110(a)(2)(C) to the extent it refers to permit programs (known as ‘‘nonattainment new source review (NSR)’’) required under part D, and (ii) section 110(a)(2)(I), pertaining to the nonattainment planning requirements of part D. As a result, this action does not address infrastructure elements related to the nonattainment NSR portion of section 110(a)(2)(C) or related to 110(a)(2)(I). This action also does not address the ‘‘interstate transport’’ requirements of element 110(a)(2)(D)(i). In a separate action, EPA approved the State’s submission to meet the requirements of 110(a)(2)(D)(i) for the 1997 ozone NAAQS (73 FR 26019). IV. How did the State of Wyoming address the infrastructure elements of section 110(a)(2)? 1. Emission limits and other control measures: Section 110(a)(2)(A) requires SIPs to include enforceable emission limitations and other control measures, means, or techniques (including economic incentives such as fees, marketable permits, and auctions of emissions rights), as well as schedules and timetables for compliance as may be necessary or appropriate to meet the applicable requirements of this Act. E:\FR\FM\23MYP1.SGM 23MYP1 emcdonald on DSK2BSOYB1PROD with PROPOSALS 29682 Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Proposed Rules a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory documents: Control Strategy Document, Source Surveillance Document and Compliance Schedule Document approved by EPA May 31, 1972 (37 FR 10842). Regulatory Documents: Wyoming Air Quality Standards and Regulations (WAQSR), Section 2, Definitions; Section 18, Diluting and concealing emissions; Section 19, Abnormal conditions and equipment malfunction; Section 14, Control of particulate emissions; and, Section 10, Nitrogen oxides, approved by EPA May 31, 1972 (37 FR 10842). WAQSR, Section 4, Sulfur oxides, approved by EPA June 10, 1975 (40 FR 24726). WAQSR, Section 12, Carbon monoxide and Section 9, Hydrocarbons, approved by EPA on May 31, 1972 (37 FR 10842). WAQSR, Section 4, Sulfur oxides, approved by EPA June 10, 1975 (40 FR 24726). WAQSR, Section 5, Sulfuric acid mist, approved by EPA May 31, 1972 (37 FR 10842). WAQSR, Section 25, Sweetwater County nonattainment area particulate matter regulations, approved by EPA July 2, 1979 (44 FR 38473). WAQSR, Section 13, Open burning restrictions, Section 15, Wood waste burners, Section 17, Motor vehicle pollution, approved by EPA May 31, 1972 (37 FR 10842). Chapter 1, Section 3, Definitions; Section 4, Diluting and concealing emissions; Section 5, Abnormal conditions and equipment malfunction; Chapter 3, Section 2, Emission standards for particulate matter; Section 3, Emission standards for nitrogen oxides; Section 4, Emission standard for sulfur oxides; Section 5, Emission standards for carbon monoxide; Section 6, Emission standards for volatile organic compounds; Chapter 4, Section 2, Existing sulfuric acid production units; Section 3, Existing nitric acid manufacturing plans; Chapter 8, Section 2, Sweetwater County particular matter regulations, Section 3, Conformity of general federal actions to state implementation plans; Chapter 10, Section 2, Open burning restrictions; Section 3, Wood waste burners; Chapter 13, Section 2, Motor vehicle pollution control, approved by EPA July 28, 2004 (69 FR 44965). b. EPA analysis: Wyoming’s SIP meets the requirements of CAA section 110(a)(2)(A) for the 1997 ozone NAAQS, subject to the following clarifications. First, Wyoming has no areas designated as nonattainment for the 1997 ozone NAAQS and, therefore, is not required to establish enforceable emission limitations or other emission reduction VerDate Mar<15>2010 16:40 May 20, 2011 Jkt 223001 measures to attain the 1997 ozone NAAQS. The SIP provisions cited by Wyoming include emissions limitations for ozone precursors: Nitrogen oxides (WAQSR Chapter 3, section 3), and volatile organic compounds (WAQSR Chapter 3, section 6). These emissions limitations meet the requirements of 110(a)(2)(A) for the 1997 ozone NAAQS. Second, in this action, EPA is not proposing to approve or disapprove any existing state rules with regard to director’s discretion or variance provisions. A number of states have such provisions which are contrary to the CAA and existing EPA guidance (52 FR 45109, Nov. 24, 1987), and the Agency plans to take action in the future to address such state regulations. In the meantime, EPA encourages any state having a director’s discretion or variance provision which is contrary to the CAA and EPA guidance to take steps to correct the deficiency as soon as possible. Finally, in this action, EPA is also not proposing to approve or disapprove any existing state provisions with regard to excess emissions during startup, shutdown, or malfunction (SSM) of operations at a facility. A number of states have SSM provisions which are contrary to the CAA and existing EPA guidance 2 and the Agency plans to address such state regulations in the future. In the meantime, EPA encourages any state having a deficient SSM provision to take steps to correct it as soon as possible. 2. Ambient air quality monitoring/ data system: Section 110(a)(2)(B) requires SIPs to provide for establishment and operation of appropriate devices, methods, systems, and procedures necessary to (i) monitor, compile, and analyze data on ambient air quality, and (ii) upon request, make such data available to the Administrator. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory documents: Air Quality Surveillance Document, approved by EPA May 31, 1972 (37 FR 10842); Air Quality Surveillance Network Document, approved by EPA February 9, 1982 (47 FR 5892); Implementation Plan for Lead, approved by EPA October 11, 1984 (49 FR 39843). Regulatory documents: WAQSR, Section 3, 2 Steven Herman, Assistant Administrator for Enforcement and Compliance Assurance, and Robert Perciasepe, Assistant Administrator for Air and Radiation, Memorandum to EPA Air Division Directors, ‘‘State Implementation Plans (SIPs): Policy Regarding Excess Emissions During Malfunctions, Startup, and Shutdown.’’ (Sept. 20, 1999).

Chapter 2, Section 2, Ambient standards for particular matter; Section 3, Ambient standards for nitrogen oxides; Section 4, Ambient standards for sulfur oxides, Section 5, Ambient standards for carbon monoxide; Section 6, Ambient standards for ozone; Section 8, Ambient standards for suspended sulfates; and, Section 10, Ambient standards for lead, approved by EPA July 28, 2004 (69 FR 44965). b. EPA analysis: Wyoming’s air monitoring programs and data systems meet the requirements of CAA section 110(a)(2)(B) for the 1997 ozone NAAQS. The Wyoming Ambient Air Monitoring Annual Network Plan, 2009, was approved by EPA Region 8 on December 3, 2009. 3. Program for enforcement of control measures: Section 110(a)(2)(C) requires SIPs to include a program to provide for the enforcement of the measures described in subparagraph (A), and regulation of the modification and construction of any stationary source within the areas covered by the plan as necessary to assure that NAAQS are achieved, including a permit program as required in parts C and D. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory documents: Legal authority document; Source Surveillance document; Review of New Sources and Modifications Document, approved by EPA May 31, 1972 (37 FR 10842). Regulatory documents: 1974 WAQSR, Section 21, Permit requirements for construction, modification and operation, approved by EPA June 10, 1975 (40 FR 24726); 1979 WAQSR, Section 24, Prevention of significant deterioration, approved by EPA July 2, 1979 (44 FR 38473). Chapter 6, Section 2, Permit requirements for construction, modification, and operation and Section 4, Prevention of significant deterioration, approved by EPA July 28, 2004 (69 FR 44965). b. EPA analysis: As explained above, in this action EPA is not evaluating nonattainment related provisions, such as the nonattainment NSR program required by part D of the Act. In addition, Wyoming has no nonattainment areas for the 1997 ozone NAAQS and is therefore not required at this point to have a corresponding nonattainment NSR program. EPA is evaluating the State’s prevention of E:\FR\FM\23MYP1.SGM 23MYP1 Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Proposed Rules significant deterioration (PSD) program as required by part C of the Act, and the State’s minor NSR program as required by 110(a)(2)(C). emcdonald on DSK2BSOYB1PROD with PROPOSALS GHG Regulation Wyoming’s PSD program was most recently approved by EPA on July 16, 2008. As described in our notice of approval (73 FR 40750), Wyoming’s PSD program at that date met the general requirements of CAA section 110(a)(2)(C). However, on June 3, 2010, EPA promulgated the ‘‘Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule’’ (‘‘Tailoring Rule’’) (75 FR 31514), setting out requirements for application of PSD to emissions sources of greenhouse gases (GHG). On December 13, 2010, EPA issued a finding of substantial inadequacy and SIP call for seven states, including Wyoming, on the basis that the states’ SIP-approved PSD programs did not apply PSD to GHG-emitting sources as required under the Tailoring Rule (75 FR 77698). Next, on December 29, 2010, EPA issued a finding that the seven states had failed to submit revisions to their SIPs as necessary to correct this inadequacy (75 FR 81874). Finally, on December 30, 2010, EPA established a federal implementation plan (FIP) in the seven states to ensure that PSD permits for sources emitting GHGs could be issued in accordance with the Tailoring Rule (75 FR 82246). As the Wyoming PSD program is currently subject to a finding of substantial inadequacy and SIP call, and Wyoming has not taken steps to remedy the inadequacy, EPA proposes in this action to disapprove the Wyoming infrastructure SIP for each infrastructure element that requires the SIP to contain a PSD program that meets the requirements of part C of title I of the Act. These elements are 110(a)(2)(C) and (J). Ozone Precursors In addition, in order for the State’s SIP-approved PSD program to satisfy the requirements of section 110(a)(2)(C) for the 1997 ozone NAAQS, the program must properly regulate ozone precursors. On November 29, 2005, EPA promulgated the phase 2 implementation rule for the 1997 ozone NAAQS (Phase 2 Rule), which includes requirements for PSD programs to treat nitrogen oxides (NOx) as a precursor for ozone (72 FR 71612). Wyoming has adopted revisions to its PSD program to meet the requirements of the Phase 2 rule, and submitted these revisions to EPA on May 10, 2011. EPA proposes in this action to concurrently approve the PSD program updates in Wyoming’s VerDate Mar<15>2010 16:40 May 20, 2011 Jkt 223001 May 11, 2011 submittal, including approval of the revisions which meet the requirements of the Phase 2 Rule. In particular, the revisions in Chapter 6, section 4(a) to the definitions of ‘‘major modification,’’ ‘‘major stationary source,’’ ‘‘regulated NSR pollutant,’’ and ‘‘significant’’ meet the requirements of 40 CFR 51.166(b)(2)(ii), (b)(1)(ii), (b)(49)(i)(a), and (b)(23)(i), respectively, as amended by the Phase 2 Rule (see 70 FR at 71699–700). In addition, the revision to section 4(b)(i)(E)(vi)(1)(e) meets the requirements of the footnote to 40 CFR 51.166(i)(5)(i)(e). Contingent on final approval of these revisions, Wyoming’s SIP meets the requirement of infrastructure element 110(a)(2)(C) to include a PSD program that properly regulates ozone precursors. This approval does not negate the disapproval (discussed in the previous paragraph) based on the finding of substantial inadequacy and SIP call. EPA also proposes approval of the portions of Wyoming’s May 11, 2011 submission which update the State’s PSD program to comply with the NSR implementation rule for PM2.5 (73 FR 28321, May 16, 2008), and the inserted definition of ‘‘replacement unit,’’ which reflects the language of 40 CFR 51.166 (b)(32)(i) through (iv). In particular, the revisions in Chapter 6, section 4(a) to the definitions of ‘‘regulated NSR pollutant’’ and ‘‘significant’’ meet the requirements of 40 CFR 51.166 (b)(49)(i)(b), (c), (d), and (b)(49)(vi); and (b)(23)(i), respectively, as amended by the PM2.5 NSR implementation rule (see 73 FR at 28348). In addition, the revisions to section 4(b)(i)(E)(vi)(2) and (3) meet the requirements of 40 CFR 51.166(i)(5)(ii) and (iii), respectively. Minor NSR Finally, with regards to minor NSR, in this action EPA is proposing to approve Wyoming’s infrastructure SIP for the 1997 ozone NAAQS with respect to the general requirement in section 110(a)(2)(C) to include a program in the SIP that regulates the modification and construction of any stationary source as necessary to assure that the NAAQS are achieved. Wyoming’s approved minor NSR program is found in Chapter 6, section 2 of the WAQSR. EPA previously approved Wyoming’s minor NSR program into the SIP (at that time as Chapter 1, section 21), and has subsequently approved revisions to the program, and at those times there were no objections to the provisions of this program. (See, for example, 47 FR 5892, Feb. 9, 1982.) Since then, the State and EPA have relied on the State’s existing minor NSR program to assure that new and modified sources not captured by PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 29683 the major NSR permitting programs do not interfere with attainment and maintenance of the NAAQS. EPA is not proposing to approve or disapprove the State’s existing minor NSR program itself to the extent that it is inconsistent with EPA’s regulations governing this program. A number of states may have minor NSR provisions that are contrary to the existing EPA regulations for this program. EPA intends to work with states to reconcile state minor NSR programs with EPA’s regulatory provisions for the program. The statutory requirements of section 110(a)(2)(C) provide for considerable flexibility in designing minor NSR programs, and it may be time to revisit the regulatory requirements for this program to give the states an appropriate level of flexibility to design a program that meets their particular air quality concerns, while assuring reasonable consistency across the country in protecting the NAAQS with respect to new and modified minor sources. 4. Interstate transport: Section 110(a)(2)(D)(i) requires SIPs to contain adequate provisions prohibiting, consistent with the provisions of this title, any source or other type of emissions activity within the state from emitting any air pollutant in amounts which will (I) contribute significantly to nonattainment in, or interfere with maintenance by, any other state, with respect to any such national primary or secondary ambient air quality standard, or (II) interfere with measures required to be included in the applicable implementation plan for any other state under part C to prevent significant deterioration of air quality or to protect visibility. a. Wyoming’s response to this requirement: Wyoming submitted its Interstate Transport SIP to EPA on May 25, 2007. b. EPA Analysis: EPA approved the State’s Interstate Transport provisions for the 1997 ozone NAAQS on May 8, 2008 (73 FR 26019). EPA is taking no action relevant to section 110(a)(2)(D)(i) in this proposal. 5. Interstate and International transport provisions: Section 110(a)(2)(D)(ii) requires that each SIP shall contain adequate provisions insuring compliance with applicable requirements of sections 126 and 115 (relating to interstate and international pollution abatement). a. Wyoming’s response to this requirement: Wyoming did not cite any specific provisions relevant to this requirement. b. EPA Analysis: Section 126(a) requires notification to affected, nearby E:\FR\FM\23MYP1.SGM 23MYP1 emcdonald on DSK2BSOYB1PROD with PROPOSALS 29684 Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Proposed Rules states of major proposed new (or modified) sources. Sections 126(b) and (c) pertain to petitions by affected States to the Administrator regarding sources violating the ‘‘interstate transport’’ provisions of section 110(a)(2)(D)(i). Section 115 similarly pertains to international transport of air pollution. WAQSR Chapter 6, Section 2, specifically paragraph (m) meets the requirements of CAA section 126(a) for the 1997 ozone NAAQS. Final approval of this language became effective January 30, 1995 (59 FR 60902, Nov. 29, 1994). Final approval of the renumbering of this language became effective August 27, 2004 (See 69 FR 44965, July 28, 2004). Wyoming has no pending obligations under sections 126(c) or 115(b); therefore, its SIP currently meets the requirements of those sections. The SIP therefore meets the requirements of 110(a)(2)(D)(ii) for the 1997 ozone NAAQS. 6. Adequate resources: Section 110(a)(2)(E) requires states to provide (i) necessary assurances that the state will have adequate personnel, funding, and authority under state law to carry out the SIP (and is not prohibited by any provision of federal or state law from carrying out the SIP or portion thereof), (ii) requires that the state comply with the requirements respecting state boards under section 128, and (iii) necessary assurances that, where the state has relied on a local or regional government, agency, or instrumentality for the implementation of any SIP provision, the state has responsibility for ensuring adequate implementation of such SIP provision. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory documents: Resources and legal authority document submitted to EPA on January 28, 1972 and approved by EPA on May 31, 1972 (37 FR 10842). Regulatory document: Chapter 1, Section 2, Authority, approved by EPA on July 28, 2004 (69 FR 44965). b. EPA Analysis: The provisions in Articles 1 and 2 of the Wyoming Environmental Quality Act (Chapter 11, Title 35 of the Wyoming Statutes) give the State adequate authority to carry out the SIP. The composition of the Wyoming Council of Environmental Quality is governed by section 35–11– 111(a) of the Wyoming Statutes. Finally, the State receives sections 103 and 105 grant funds through its Performance Partnership Grant along with required state matching funds to provide funding necessary to carry out Wyoming’s SIP requirements. The requirements of VerDate Mar<15>2010 16:40 May 20, 2011 Jkt 223001 section 110(a)(2)(E) for the 1997 ozone NAAQS are therefore met. 7. Stationary source monitoring system: Section 110(a)(2)(F) requires (i) the installation, maintenance, and replacement of equipment, and the implementation of other necessary steps, by owners or operators of stationary sources to monitor emissions from such sources, (ii) periodic reports on the nature and amounts of emissions and emissions-related data from such sources, and (iii) correlation of such reports by the state agency with any emission limitations or standards established pursuant to the Act, which reports shall be available at reasonable times for public inspection. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Regulatory documents: 1979 WAQSR, Section 23, Continuous monitoring requirements for existing sources, approved by EPA on July 2, 1979 (44 FR 38473) and Chapter 7, Section 2, Continuous monitoring requirements for existing sources, approved by EPA on July 28, 2004 (69 FR 44965). b. EPA Analysis: In addition to the specific monitoring provisions cited by Wyoming, the SIP provides for monitoring, recordkeeping, and reporting requirements for sources subject to minor and major source permitting. (See WAQSR Chapter 6, section 2.) Wyoming’s SIP therefore meets the requirements of section 110(a)(2)(F) for the 1997 ozone NAAQS. 8. Emergency power: Section 110(a)(2)(G) requires states to provide for authority to address activities causing imminent and substantial endangerment to public health, including contingency plans to implement the emergency episode provisions in their SIPs. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory documents: Emergency Episode Plan Document, approved by EPA May 31, 1972 (37 FR 10842); Emergency Episode Contingency Plan Document, approved by EPA February 9, 1982 (47 FR 5892). Regulatory documents: 1971 WAQSR, Section 20, Air Pollution emergency episodes, approved by EPA May 31, 1972 (37 FR 10842) and Chapter 12, Section 2, Air pollution emergency episodes, approved by EPA July 28, 2004 (69 FR 44965). b. EPA analysis: Section 35–11–115 of the Wyoming Statutes gives the Director of the Wyoming Department of Environmental Quality (DEQ) comparable emergency powers to those in section 303 of the Act. Furthermore, Wyoming has not monitored any values PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 above the priority cut point for ozone (see 40 CFR 51.150(b)(5)), and is not required at this point to have a contingency plan for ozone that meets the requirements of 40 CFR part 51, subpart H. The SIP therefore meets the requirements of 110(a)(2)(G) for the 1997 ozone NAAQS. 9. Future SIP revisions: Section 110(a)(2)(H) requires that SIPs provide for revision of such plan (i) from time to time as may be necessary to take account of revisions of such national primary or secondary ambient air quality standard or the availability of improved or more expeditious methods of attaining such standard, and (ii), except as provided in paragraph (3)(C), whenever the Administrator finds on the basis of information available to the Administrator that the SIP is substantially inadequate to attain the NAAQS which it implements or to otherwise comply with any additional requirements under this Act. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory document: Implementation Plan Review Document, approved by EPA April 19, 1983 (48 FR 16682). b. EPA analysis: The general provisions in Article 1 of the Wyoming Environmental Quality Act (Article 1, Chapter 11, Title 35 of the Wyoming Statutes) and the particular provision in Article 2 at section 35–11–202 of the Wyoming Statutes give the State sufficient authority to revise the SIP as required by section 110(a)(2)(H). 10. Nonattainment Area Plan or Plan Revision under Part D: Section 110(a)(2)(I) requires that a SIP or SIP revision for an area designated as a nonattainment area must meet the applicable requirements of part D of this subchapter (relating to nonattainment areas). a. EPA analysis for Section 110(a)(2)(I): As noted above, the specific nonattainment area plan requirements of Section 110(a)(2)(I) are subject to the timing requirement of Section 172, not the timing requirement of Section 110(a)(1). This element is therefore not applicable to this action. EPA will take action on part D attainment plans through a separate process. 11. Consultation with government officials, public notification, PSD and visibility protection: Section 110(a)(2)(J) requires that each SIP meet the applicable requirements of section 121 of this title (relating to consultation), section 127 of this title (relating to public notification), and part C of this subchapter (relating to prevention of significant deterioration of air quality and visibility protection). E:\FR\FM\23MYP1.SGM 23MYP1 emcdonald on DSK2BSOYB1PROD with PROPOSALS Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Proposed Rules a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory document: Consultation document, approved by EPA July 2, 1979 (44 FR 38473). Regulatorydocument: 1979 WAQSR, Section 24, Prevention of significant deterioration, approved by EPA on July 2, 1979 (44 FR 38473); Chapter 7, Section 4, Prevention of significant deterioration, approved by EPA 7/28/04 (69 FR 44965) b. EPA Analysis: The State has demonstrated that it has the authority and rules in place to provide a process of consultation with general purpose local governments, designated organizations of elected officials of local governments and any Federal Land Manager having authority over federal land to which the SIP applies, consistent with the requirements of CAA section 121. Furthermore, EPA previously approved portions of the Wyoming SIP meeting the requirements of CAA section 127. (44 FR 38473, July 2, 1979.) As noted above, the State has a SIPapproved PSD program. EPA has further evaluated Wyoming’s SIP-approved PSD program in this proposed action under IV.3, element 110(a)(2)(C). For the same reasons as discussed in subsection IV.3, EPA proposes to disapprove the Wyoming infrastructure SIP for the 1997 ozone NAAQS specifically for the requirement in section 110(a)(2)(J) that the SIP meet the applicable requirements of part C of title I of the Act, in particular with regards to the requirement that the PSD program apply to GHG sources in accordance with the Tailoring Rule. Finally, with regard to the applicable requirements for visibility protection, EPA recognizes that states are subject to visibility and regional haze program requirements under part C of the act. In the event of the establishment of a new NAAQS, however, the visibility and regional haze program requirements under part C do not change. Thus we find that there is no new visibility obligation ‘‘triggered’’ under section 110(a)(2)(J) when a new NAAQS becomes effective. 12. Air quality and modeling/data: Section 110(a)(2)(K) requires that each SIP provide for (i) the performance of such air quality modeling as the Administrator may prescribe for the purpose of predicting the effect on ambient air quality of any emissions of any air pollutant for which the Administrator has established a NAAQS, and (ii) the submission, upon request, of data related to such air quality modeling to the Administrator. VerDate Mar<15>2010 16:40 May 20, 2011 Jkt 223001 a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Regulatory Documents: 1974 WAQSR, Section 21, Permit requirements for construction, modification and operation, approved by EPA on June 10, 1975 (40 FR 24726); 1979 WAQSR, Section 24, Prevention of significant deterioration, approved by EPA on July 2, 1979 (44 FR 38473); Chapter 6, Section 2, Permit requirements for construction, modification, and operation, approved by EPA on July 28, 2004 (69 FR 44965); Chapter 6, Section 4, Prevention of significant deterioration, approved by EPA on July 28, 2004 (69 FR 44965). b. EPA Analysis: Wyoming’s SIP meets the requirements of CAA section 110(a)(2)(K) for the 1997 ozone NAAQS. In particular, Wyoming’s PSD program requires that estimates of ambient air concentrations be based on applicable air quality models specified in Appendix W of 40 CFR part 51, and that modification or substitution of a model specified in Appendix W must be approved by the Administrator. (See WAQSR Chapter 6, section 4(b)(iv).) As a result, the SIP provides for such air quality modeling as the Administrator has prescribed. 13. Permitting fees: Section 110(a)(2)(L) requires SIPs to require the owner or operator of each major stationary source to pay to the permitting authority, as a condition of any permit required under this act, a fee sufficient to cover (i) the reasonable costs of reviewing and acting upon any application for such a permit, and (ii) if the owner or operator receives a permit for such source, the reasonable costs of implementing and enforcing the terms and conditions of any such permit (not including any court costs or other costs associated with any enforcement action), until such fee requirement is superseded with respect to such sources by the Administrator’s approval of a fee program under title V. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Regulatory Documents: 1993 WAQSR, Section 21, Permit requirements for construction, modification, and operation, approved by EPA on 11/29/94 (59 FR 60905); Chapter 6, Section 2, Permit requirements for construction, modification and operation, approved by EPA on July 28, 2004 (69 FR 44965). b. EPA Analysis: Wyoming’s approved title V operating permit program meets the requirements of CAA section 111(a)(2)(L) for the 1997 ozone NAAQS. Final approval of the title V operating permit program became effective April 23, 1999 (64 FR 8523, Feb. 22, 1990). PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 29685 Interim approval of Wyoming’s title V operating permit program became effective February 21, 1995 (60 FR 4563, Jan. 19, 1995). As discussed in a previous direct final rule (which received comments) for interim approval of the title V program (59 FR 48802, Sept. 23, 1994), the State demonstrated that the fees collected were sufficient to administer the program. 14. Consultation/participation by affected local entities: Section 110(a)(2)(M) requires states to provide for consultation and participation in SIP development by local political subdivisions affected by the SIP. a. Wyoming’s response to this requirement: Wyoming cited the following SIP provisions: Nonregulatory document: Intergovernmental Cooperation Document, approved by EPA on May 31, 1972 (37 FR 10842). b. EPA Analysis: Wyoming’s submittal meets the requirements of CAA Section 110(a)(2)(M) for the 1997 ozone NAAQS. V. What action is EPA taking? In this action, EPA is proposing to approve the following infrastructure elements for the 1997 ozone NAAQS: (A), (B), (C) with regards to the requirement to have a minor NSR program, (D)(ii), (E), (F), (G), (H), (J) with regards to the requirements related to sections 121 and 127 of the Act, (K), (L), and (M). In this action, EPA also proposes approval of the State’s May 11, 2011 submission, updating the Wyoming PSD program to, among other things, regulate NOX as a precursor to ozone. Contingent on final approval of these updates, EPA is proposing to approve portions of infrastructure elements (C) and (J) for the 1997 ozone NAAQS with regards to the requirement that the State’s SIPapproved PSD program properly regulate ozone precursors. In this action, EPA is proposing to disapprove the following infrastructure elements for the 1997 ozone NAAQS: (C) and (J) with regards to the requirement that the State’s PSD program regulate GHG-emitting sources in accordance with the Tailoring Rule. In this action, EPA is taking no action on infrastructure elements (D)(i), (I), and (J) specifically in regard to visibility, for the 1997 ozone NAAQS. VI. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations (42 U.S.C. 7410(k), 40 CFR 52.02(a)). E:\FR\FM\23MYP1.SGM 23MYP1 emcdonald on DSK2BSOYB1PROD with PROPOSALS 29686 Federal Register / Vol. 76, No. 99 / Monday, May 23, 2011 / Proposed Rules Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this proposed action merely approves some state law as meeting Federal requirements and disapproves other state law because it does not meet Federal requirements; this proposed action does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action: • Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and, • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on Tribal governments or preempt Tribal law.

Approval and Disapproval and Promulgation of State Implementation 
Plan Revisions; Infrastructure Requirements for the 1997 8-Hour Ozone 
National Ambient Air Quality Standards; Wyoming

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to partially approve and partially disapprove 
the State Implementation Plan (SIP) submission from the State of 
Wyoming to demonstrate that the SIP meets the requirements of Sections 
110(a)(1) and (2) of the Clean Air Act (CAA) for the National Ambient 
Air Quality Standards (NAAQS) promulgated for ozone on July 18, 1997. 
Section 110(a)(1) of the CAA requires that each state, after a new or 
revised NAAQS is promulgated, review their SIPs to ensure that they 
meet the requirements of the ``infrastructure elements'' of section 
110(a)(2). The State of Wyoming submitted two certifications of their 
infrastructure SIP for the 1997 ozone NAAQS, date December 7, 2007 and 
December 10, 2009. EPA does not propose to act on the State's May 25, 
2007 submission to meet the requirements of section 110(a)(2)(D)(i) of 
the CAA, relating to interstate transport of air pollution, for the 
1997 ozone NAAQS. EPA approved the State's interstate transport SIP 
submission on May 8, 2008 (73 FR 26019). EPA is also proposing to 
approve a Wyoming submittal, dated May 10, 2011, revising the State's 
Prevention of Significant Deterioration (PSD) program.

DATES: Written comments must be received on or before June 22, 2011.

II. Background

    On July 18, 1997, EPA promulgated new NAAQS for ozone based on 8-
hour average concentrations. The 8-hour averaging period replaced the 
previous 1-hour averaging period, and the level of the NAAQS was 
changed from 0.12 parts per million (ppm) to 0.08 ppm (62 FR 38856). By 
statute, SIPs meeting the requirements of sections 110(a)(1) and (2) 
are to be submitted by states within three years after promulgation of 
a new or revised standard. Section 110(a)(2) provides basic 
requirements for SIPs, including emissions inventories, monitoring, and 
modeling, to assure attainment and maintenance of the standards. These 
requirements are set out in several ``infrastructure elements,'' listed 
in section 110(a)(2).
    Section 110(a) imposes the obligation upon states to make a SIP 
submission to EPA for a new or revised NAAQS, and the contents of that 
submission may vary depending upon the facts and circumstances. In 
particular, the data and analytical tools available at the time the 
state develops and submits the SIP for a new or revised NAAQS affects 
the content of the submission. The contents of such SIP submissions may 
also vary depending upon what provisions the state's existing SIP 
already contains. In the case of the 1997 ozone NAAQS, states typically 
have met the basic program elements required in section 110(a)(2) 
through earlier SIP submissions in connection with previous NAAQS. In a 
guidance issued on October 2, 2007, EPA noted that, to the extent an 
existing SIP already meets the section 110(a)(2) requirements, states 
need only to certify that fact via a letter to EPA.\1\
---------------------------------------------------------------------------

    \1\ Memorandum from William T. Harnett, Director, Air Quality 
Policy Division, ``Guidance on SIP Elements Required Under Sections 
110(a)(1) and (2) for the 1997 8-hour Ozone and PM2.5 
National Ambient Air Quality Standards'' (Oct. 2, 2007).
---------------------------------------------------------------------------

    On March 27, 2008, EPA published a final rule entitled, 
``Completeness Findings for Section 110(a) State Implementation Plans 
for the 8-hour Ozone NAAQS'' (73 FR 16205). In the rule, EPA made a 
finding for each State that it had submitted or had failed to submit a 
complete SIP that provided the basic program elements of section 
110(a)(2) necessary to implement the 1997 8-hour ozone NAAQS. In 
particular, EPA found that Wyoming had submitted a complete SIP to meet 
these requirements.

III. What infrastructure elements are required under sections 110(a)(1) 
and (2)?

    Section 110(a)(1) provides the procedural and timing requirements 
for SIP submissions after a new or revised NAAQS is promulgated. 
Section 110(a)(2) lists specific elements the SIP must contain or 
satisfy. These infrastructure elements include requirements, such as 
modeling, monitoring, and emissions inventories that are designed to 
assure attainment and maintenance of the NAAQS. The elements that are 
the subject of this action are listed below.
     110(a)(2)(A): Emission limits and other control measures.
     110(a)(2)(B): Ambient air quality monitoring/data system.
     110(a)(2)(C): Program for enforcement of control measures.
     110(a)(2)(D)(ii): Interstate and international pollution.
     110(a)(2)(E): Adequate resources and authority.
     110(a)(2)(F): Stationary source monitoring and reporting.
     110(a)(2)(G): Emergency powers.
     110(a)(2)(H): Future SIP revisions.
     110(a)(2)(J): Consultation with government officials; 
public notification; and prevention of significant deterioration (PSD) 
and visibility protection.
     110(a)(2)(K): Air quality modeling/data.
     110(a)(2)(L): Permitting fees.
     110(a)(2)(M): Consultation/participation by affected local 
entities.

A detailed discussion of each of these elements is contained in the 
next section.
    Two elements identified in section 110(a)(2) are not governed by 
the three-year submission deadline of section 110(a)(1) and are 
therefore not addressed in this action. These elements relate to part D 
of Title I of the CAA, and submissions to satisfy them are not due 
within three years after promulgation of a new or revised NAAQS, but 
rather are due at the same time nonattainment area plan requirements 
are due under section 172. The two elements are: (i) section 
110(a)(2)(C) to the extent it refers to permit programs (known as 
``nonattainment new source review (NSR)'') required under part D, and 
(ii) section 110(a)(2)(I), pertaining to the nonattainment planning 
requirements of part D. As a result, this action does not address 
infrastructure elements related to the nonattainment NSR portion of 
section 110(a)(2)(C) or related to 110(a)(2)(I).
    This action also does not address the ``interstate transport'' 
requirements of element 110(a)(2)(D)(i). In a separate action, EPA 
approved the State's submission to meet the requirements of 
110(a)(2)(D)(i) for the 1997 ozone NAAQS (73 FR 26019).

IV. How did the State of Wyoming address the infrastructure elements of 
section 110(a)(2)?

    1. Emission limits and other control measures: Section 110(a)(2)(A) 
requires SIPs to include enforceable emission limitations and other 
control measures, means, or techniques (including economic incentives 
such as fees, marketable permits, and auctions of emissions rights), as 
well as schedules and timetables for compliance as may be necessary or 
appropriate to meet the applicable requirements of this Act.

[[Page 29682]]

    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory documents: Control Strategy 
Document, Source Surveillance Document and Compliance Schedule Document 
approved by EPA May 31, 1972 (37 FR 10842). Regulatory Documents: 
Wyoming Air Quality Standards and Regulations (WAQSR), Section 2, 
Definitions; Section 18, Diluting and concealing emissions; Section 19, 
Abnormal conditions and equipment malfunction; Section 14, Control of 
particulate emissions; and, Section 10, Nitrogen oxides, approved by 
EPA May 31, 1972 (37 FR 10842). WAQSR, Section 4, Sulfur oxides, 
approved by EPA June 10, 1975 (40 FR 24726). WAQSR, Section 12, Carbon 
monoxide and Section 9, Hydrocarbons, approved by EPA on May 31, 1972 
(37 FR 10842). WAQSR, Section 4, Sulfur oxides, approved by EPA June 
10, 1975 (40 FR 24726). WAQSR, Section 5, Sulfuric acid mist, approved 
by EPA May 31, 1972 (37 FR 10842). WAQSR, Section 25, Sweetwater County 
non-attainment area particulate matter regulations, approved by EPA 
July 2, 1979 (44 FR 38473). WAQSR, Section 13, Open burning 
restrictions, Section 15, Wood waste burners, Section 17, Motor vehicle 
pollution, approved by EPA May 31, 1972 (37 FR 10842). Chapter 1, 
Section 3, Definitions; Section 4, Diluting and concealing emissions; 
Section 5, Abnormal conditions and equipment malfunction; Chapter 3, 
Section 2, Emission standards for particulate matter; Section 3, 
Emission standards for nitrogen oxides; Section 4, Emission standard 
for sulfur oxides; Section 5, Emission standards for carbon monoxide; 
Section 6, Emission standards for volatile organic compounds; Chapter 
4, Section 2, Existing sulfuric acid production units; Section 3, 
Existing nitric acid manufacturing plans; Chapter 8, Section 2, 
Sweetwater County particular matter regulations, Section 3, Conformity 
of general federal actions to state implementation plans; Chapter 10, 
Section 2, Open burning restrictions; Section 3, Wood waste burners; 
Chapter 13, Section 2, Motor vehicle pollution control, approved by EPA 
July 28, 2004 (69 FR 44965).
    b. EPA analysis: Wyoming's SIP meets the requirements of CAA 
section 110(a)(2)(A) for the 1997 ozone NAAQS, subject to the following 
clarifications. First, Wyoming has no areas designated as nonattainment 
for the 1997 ozone NAAQS and, therefore, is not required to establish 
enforceable emission limitations or other emission reduction measures 
to attain the 1997 ozone NAAQS. The SIP provisions cited by Wyoming 
include emissions limitations for ozone precursors: Nitrogen oxides 
(WAQSR Chapter 3, section 3), and volatile organic compounds (WAQSR 
Chapter 3, section 6). These emissions limitations meet the 
requirements of 110(a)(2)(A) for the 1997 ozone NAAQS.
    Second, in this action, EPA is not proposing to approve or 
disapprove any existing state rules with regard to director's 
discretion or variance provisions. A number of states have such 
provisions which are contrary to the CAA and existing EPA guidance (52 
FR 45109, Nov. 24, 1987), and the Agency plans to take action in the 
future to address such state regulations. In the meantime, EPA 
encourages any state having a director's discretion or variance 
provision which is contrary to the CAA and EPA guidance to take steps 
to correct the deficiency as soon as possible.
    Finally, in this action, EPA is also not proposing to approve or 
disapprove any existing state provisions with regard to excess 
emissions during startup, shutdown, or malfunction (SSM) of operations 
at a facility. A number of states have SSM provisions which are 
contrary to the CAA and existing EPA guidance \2\ and the Agency plans 
to address such state regulations in the future. In the meantime, EPA 
encourages any state having a deficient SSM provision to take steps to 
correct it as soon as possible.

1999).
---------------------------------------------------------------------------

    2. Ambient air quality monitoring/data system: Section 110(a)(2)(B) 
requires SIPs to provide for establishment and operation of appropriate 
devices, methods, systems, and procedures necessary to (i) monitor, 
compile, and analyze data on ambient air quality, and (ii) upon 
request, make such data available to the Administrator.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory documents: Air Quality 
Surveillance Document, approved by EPA May 31, 1972 (37 FR 10842); Air 
Quality Surveillance Network Document, approved by EPA February 9, 1982 
(47 FR 5892); Implementation Plan for Lead, approved by EPA October 11, 
1984 (49 FR 39843). Regulatory documents: WAQSR, Section 3, 
Particulates; Section 10, Nitrogen Oxides; Section 4, Sulfur oxides; 
Section 12, Carbon monoxide; Section 8, Photochemical oxidants; Section 
6, Sulfation; and, Section 27, Ambient air quality standard for lead, 
approved by EPA October 11, 1984 (49 FR 39843). Chapter 2, Section 2, 
Ambient standards for particular matter; Section 3, Ambient standards 
for nitrogen oxides; Section 4, Ambient standards for sulfur oxides, 
Section 5, Ambient standards for carbon monoxide; Section 6, Ambient 
standards for ozone; Section 8, Ambient standards for suspended 
sulfates; and, Section 10, Ambient standards for lead, approved by EPA 
July 28, 2004 (69 FR 44965).
    b. EPA analysis: Wyoming's air monitoring programs and data systems 
meet the requirements of CAA section 110(a)(2)(B) for the 1997 ozone 
NAAQS. The Wyoming Ambient Air Monitoring Annual Network Plan, 2009, 
was approved by EPA Region 8 on December 3, 2009.
    3. Program for enforcement of control measures: Section 
110(a)(2)(C) requires SIPs to include a program to provide for the 
enforcement of the measures described in subparagraph (A), and 
regulation of the modification and construction of any stationary 
source within the areas covered by the plan as necessary to assure that 
NAAQS are achieved, including a permit program as required in parts C 
and D.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory documents: Legal authority 
document; Source Surveillance document; Review of New Sources and 
Modifications Document, approved by EPA May 31, 1972 (37 FR 10842). 
Regulatory documents: 1974 WAQSR, Section 21, Permit requirements for 
construction, modification and operation, approved by EPA June 10, 1975 
(40 FR 24726); 1979 WAQSR, Section 24, Prevention of significant 
deterioration, approved by EPA July 2, 1979 (44 FR 38473). Chapter 6, 
Section 2, Permit requirements for construction, modification, and 
operation and Section 4, Prevention of significant deterioration, 
approved by EPA July 28, 2004 (69 FR 44965).
    b. EPA analysis: As explained above, in this action EPA is not 
evaluating nonattainment related provisions, such as the nonattainment 
NSR program required by part D of the Act. In addition, Wyoming has no 
nonattainment areas for the 1997 ozone NAAQS and is therefore not 
required at this point to have a corresponding nonattainment NSR 
program. EPA is evaluating the State's prevention of

[[Page 29683]]

significant deterioration (PSD) program as required by part C of the 
Act, and the State's minor NSR program as required by 110(a)(2)(C).

GHG Regulation

    Wyoming's PSD program was most recently approved by EPA on July 16, 
2008. As described in our notice of approval (73 FR 40750), Wyoming's 
PSD program at that date met the general requirements of CAA section 
110(a)(2)(C). However, on June 3, 2010, EPA promulgated the 
``Prevention of Significant Deterioration and Title V Greenhouse Gas 
Tailoring Rule'' (``Tailoring Rule'') (75 FR 31514), setting out 
requirements for application of PSD to emissions sources of greenhouse 
gases (GHG). On December 13, 2010, EPA issued a finding of substantial 
inadequacy and SIP call for seven states, including Wyoming, on the 
basis that the states' SIP-approved PSD programs did not apply PSD to 
GHG-emitting sources as required under the Tailoring Rule (75 FR 
77698). Next, on December 29, 2010, EPA issued a finding that the seven 
states had failed to submit revisions to their SIPs as necessary to 
correct this inadequacy (75 FR 81874). Finally, on December 30, 2010, 
EPA established a federal implementation plan (FIP) in the seven states 
to ensure that PSD permits for sources emitting GHGs could be issued in 
accordance with the Tailoring Rule (75 FR 82246). As the Wyoming PSD 
program is currently subject to a finding of substantial inadequacy and 
SIP call, and Wyoming has not taken steps to remedy the inadequacy, EPA 
proposes in this action to disapprove the Wyoming infrastructure SIP 
for each infrastructure element that requires the SIP to contain a PSD 
program that meets the requirements of part C of title I of the Act. 
These elements are 110(a)(2)(C) and (J).

Ozone Precursors

    In addition, in order for the State's SIP-approved PSD program to 
satisfy the requirements of section 110(a)(2)(C) for the 1997 ozone 
NAAQS, the program must properly regulate ozone precursors. On November 
29, 2005, EPA promulgated the phase 2 implementation rule for the 1997 
ozone NAAQS (Phase 2 Rule), which includes requirements for PSD 
programs to treat nitrogen oxides (NOx) as a precursor for ozone (72 FR 
71612). Wyoming has adopted revisions to its PSD program to meet the 
requirements of the Phase 2 rule, and submitted these revisions to EPA 
on May 10, 2011. EPA proposes in this action to concurrently approve 
the PSD program updates in Wyoming's May 11, 2011 submittal, including 
approval of the revisions which meet the requirements of the Phase 2 
Rule. In particular, the revisions in Chapter 6, section 4(a) to the 
definitions of ``major modification,'' ``major stationary source,'' 
``regulated NSR pollutant,'' and ``significant'' meet the requirements 
of 40 CFR 51.166(b)(2)(ii), (b)(1)(ii), (b)(49)(i)(a), and (b)(23)(i), 
respectively, as amended by the Phase 2 Rule (see 70 FR at 71699-700). 
In addition, the revision to section 4(b)(i)(E)(vi)(1)(e) meets the 
requirements of the footnote to 40 CFR 51.166(i)(5)(i)(e). Contingent 
on final approval of these revisions, Wyoming's SIP meets the 
requirement of infrastructure element 110(a)(2)(C) to include a PSD 
program that properly regulates ozone precursors. This approval does 
not negate the disapproval (discussed in the previous paragraph) based 
on the finding of substantial inadequacy and SIP call.
    EPA also proposes approval of the portions of Wyoming's May 11, 
2011 submission which update the State's PSD program to comply with the 
NSR implementation rule for PM2.5 (73 FR 28321, May 16, 
2008), and the inserted definition of ``replacement unit,'' which 
reflects the language of 40 CFR 51.166 (b)(32)(i) through (iv). In 
particular, the revisions in Chapter 6, section 4(a) to the definitions 
of ``regulated NSR pollutant'' and ``significant'' meet the 
requirements of 40 CFR 51.166 (b)(49)(i)(b), (c), (d), and (b)(49)(vi); 
and (b)(23)(i), respectively, as amended by the PM2.5 NSR 
implementation rule (see 73 FR at 28348). In addition, the revisions to 
section 4(b)(i)(E)(vi)(2) and (3) meet the requirements of 40 CFR 
51.166(i)(5)(ii) and (iii), respectively.

Minor NSR

    Finally, with regards to minor NSR, in this action EPA is proposing 
to approve Wyoming's infrastructure SIP for the 1997 ozone NAAQS with 
respect to the general requirement in section 110(a)(2)(C) to include a 
program in the SIP that regulates the modification and construction of 
any stationary source as necessary to assure that the NAAQS are 
achieved. Wyoming's approved minor NSR program is found in Chapter 6, 
section 2 of the WAQSR. EPA previously approved Wyoming's minor NSR 
program into the SIP (at that time as Chapter 1, section 21), and has 
subsequently approved revisions to the program, and at those times 
there were no objections to the provisions of this program. (See, for 
example, 47 FR 5892, Feb. 9, 1982.) Since then, the State and EPA have 
relied on the State's existing minor NSR program to assure that new and 
modified sources not captured by the major NSR permitting programs do 
not interfere with attainment and maintenance of the NAAQS. EPA is not 
proposing to approve or disapprove the State's existing minor NSR 
program itself to the extent that it is inconsistent with EPA's 
regulations governing this program. A number of states may have minor 
NSR provisions that are contrary to the existing EPA regulations for 
this program. EPA intends to work with states to reconcile state minor 
NSR programs with EPA's regulatory provisions for the program. The 
statutory requirements of section 110(a)(2)(C) provide for considerable 
flexibility in designing minor NSR programs, and it may be time to 
revisit the regulatory requirements for this program to give the states 
an appropriate level of flexibility to design a program that meets 
their particular air quality concerns, while assuring reasonable 
consistency across the country in protecting the NAAQS with respect to 
new and modified minor sources.
    4. Interstate transport: Section 110(a)(2)(D)(i) requires SIPs to 
contain adequate provisions prohibiting, consistent with the provisions 
of this title, any source or other type of emissions activity within 
the state from emitting any air pollutant in amounts which will (I) 
contribute significantly to nonattainment in, or interfere with 
maintenance by, any other state, with respect to any such national 
primary or secondary ambient air quality standard, or (II) interfere 
with measures required to be included in the applicable implementation 
plan for any other state under part C to prevent significant 
deterioration of air quality or to protect visibility.
    a. Wyoming's response to this requirement: Wyoming submitted its 
Interstate Transport SIP to EPA on May 25, 2007.
    b. EPA Analysis: EPA approved the State's Interstate Transport 
provisions for the 1997 ozone NAAQS on May 8, 2008 (73 FR 26019). EPA 
is taking no action relevant to section 110(a)(2)(D)(i) in this 
proposal.
    5. Interstate and International transport provisions: Section 
110(a)(2)(D)(ii) requires that each SIP shall contain adequate 
provisions insuring compliance with applicable requirements of sections 
126 and 115 (relating to interstate and international pollution 
abatement).
    a. Wyoming's response to this requirement: Wyoming did not cite any 
specific provisions relevant to this requirement.
    b. EPA Analysis: Section 126(a) requires notification to affected, 
nearby

[[Page 29684]]

states of major proposed new (or modified) sources. Sections 126(b) and 
(c) pertain to petitions by affected States to the Administrator 
regarding sources violating the ``interstate transport'' provisions of 
section 110(a)(2)(D)(i). Section 115 similarly pertains to 
international transport of air pollution.
    WAQSR Chapter 6, Section 2, specifically paragraph (m) meets the 
requirements of CAA section 126(a) for the 1997 ozone NAAQS. Final 
approval of this language became effective January 30, 1995 (59 FR 
60902, Nov. 29, 1994). Final approval of the renumbering of this 
language became effective August 27, 2004 (See 69 FR 44965, July 28, 
2004).
    Wyoming has no pending obligations under sections 126(c) or 115(b); 
therefore, its SIP currently meets the requirements of those sections. 
The SIP therefore meets the requirements of 110(a)(2)(D)(ii) for the 
1997 ozone NAAQS.
    6. Adequate resources: Section 110(a)(2)(E) requires states to 
provide (i) necessary assurances that the state will have adequate 
personnel, funding, and authority under state law to carry out the SIP 
(and is not prohibited by any provision of federal or state law from 
carrying out the SIP or portion thereof), (ii) requires that the state 
comply with the requirements respecting state boards under section 128, 
and (iii) necessary assurances that, where the state has relied on a 
local or regional government, agency, or instrumentality for the 
implementation of any SIP provision, the state has responsibility for 
ensuring adequate implementation of such SIP provision.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory documents: Resources and legal 
authority document submitted to EPA on January 28, 1972 and approved by 
EPA on May 31, 1972 (37 FR 10842). Regulatory document: Chapter 1, 
Section 2, Authority, approved by EPA on July 28, 2004 (69 FR 44965).
    b. EPA Analysis: The provisions in Articles 1 and 2 of the Wyoming 
Environmental Quality Act (Chapter 11, Title 35 of the Wyoming 
Statutes) give the State adequate authority to carry out the SIP. The 
composition of the Wyoming Council of Environmental Quality is governed 
by section 35-11-111(a) of the Wyoming Statutes. Finally, the State 
receives sections 103 and 105 grant funds through its Performance 
Partnership Grant along with required state matching funds to provide 
funding necessary to carry out Wyoming's SIP requirements. The 
requirements of section 110(a)(2)(E) for the 1997 ozone NAAQS are 
therefore met.
    7. Stationary source monitoring system: Section 110(a)(2)(F) 
requires (i) the installation, maintenance, and replacement of 
equipment, and the implementation of other necessary steps, by owners 
or operators of stationary sources to monitor emissions from such 
sources, (ii) periodic reports on the nature and amounts of emissions 
and emissions-related data from such sources, and (iii) correlation of 
such reports by the state agency with any emission limitations or 
standards established pursuant to the Act, which reports shall be 
available at reasonable times for public inspection.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Regulatory documents: 1979 WAQSR, Section 23, 
Continuous monitoring requirements for existing sources, approved by 
EPA on July 2, 1979 (44 FR 38473) and Chapter 7, Section 2, Continuous 
monitoring requirements for existing sources, approved by EPA on July 
28, 2004 (69 FR 44965).
    b. EPA Analysis: In addition to the specific monitoring provisions 
cited by Wyoming, the SIP provides for monitoring, recordkeeping, and 
reporting requirements for sources subject to minor and major source 
permitting. (See WAQSR Chapter 6, section 2.) Wyoming's SIP therefore 
meets the requirements of section 110(a)(2)(F) for the 1997 ozone 
NAAQS.
    8. Emergency power: Section 110(a)(2)(G) requires states to provide 
for authority to address activities causing imminent and substantial 
endangerment to public health, including contingency plans to implement 
the emergency episode provisions in their SIPs.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory documents: Emergency Episode 
Plan Document, approved by EPA May 31, 1972 (37 FR 10842); Emergency 
Episode Contingency Plan Document, approved by EPA February 9, 1982 (47 
FR 5892). Regulatory documents: 1971 WAQSR, Section 20, Air Pollution 
emergency episodes, approved by EPA May 31, 1972 (37 FR 10842) and 
Chapter 12, Section 2, Air pollution emergency episodes, approved by 
EPA July 28, 2004 (69 FR 44965).
    b. EPA analysis: Section 35-11-115 of the Wyoming Statutes gives 
the Director of the Wyoming Department of Environmental Quality (DEQ) 
comparable emergency powers to those in section 303 of the Act. 
Furthermore, Wyoming has not monitored any values above the priority 
cut point for ozone (see 40 CFR 51.150(b)(5)), and is not required at 
this point to have a contingency plan for ozone that meets the 
requirements of 40 CFR part 51, subpart H. The SIP therefore meets the 
requirements of 110(a)(2)(G) for the 1997 ozone NAAQS.
    9. Future SIP revisions: Section 110(a)(2)(H) requires that SIPs 
provide for revision of such plan (i) from time to time as may be 
necessary to take account of revisions of such national primary or 
secondary ambient air quality standard or the availability of improved 
or more expeditious methods of attaining such standard, and (ii), 
except as provided in paragraph (3)(C), whenever the Administrator 
finds on the basis of information available to the Administrator that 
the SIP is substantially inadequate to attain the NAAQS which it 
implements or to otherwise comply with any additional requirements 
under this Act.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory document: Implementation Plan 
Review Document, approved by EPA April 19, 1983 (48 FR 16682).
    b. EPA analysis: The general provisions in Article 1 of the Wyoming 
Environmental Quality Act (Article 1, Chapter 11, Title 35 of the 
Wyoming Statutes) and the particular provision in Article 2 at section 
35-11-202 of the Wyoming Statutes give the State sufficient authority 
to revise the SIP as required by section 110(a)(2)(H).
    10. Nonattainment Area Plan or Plan Revision under Part D: Section 
110(a)(2)(I) requires that a SIP or SIP revision for an area designated 
as a nonattainment area must meet the applicable requirements of part D 
of this subchapter (relating to nonattainment areas).
    a. EPA analysis for Section 110(a)(2)(I): As noted above, the 
specific nonattainment area plan requirements of Section 110(a)(2)(I) 
are subject to the timing requirement of Section 172, not the timing 
requirement of Section 110(a)(1). This element is therefore not 
applicable to this action. EPA will take action on part D attainment 
plans through a separate process.
    11. Consultation with government officials, public notification, 
PSD and visibility protection: Section 110(a)(2)(J) requires that each 
SIP meet the applicable requirements of section 121 of this title 
(relating to consultation), section 127 of this title (relating to 
public notification), and part C of this subchapter (relating to 
prevention of significant deterioration of air quality and visibility 
protection).

[[Page 29685]]

    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory document: Consultation 
document, approved by EPA July 2, 1979 (44 FR 38473). Regulatory-
document: 1979 WAQSR, Section 24, Prevention of significant 
deterioration, approved by EPA on July 2, 1979 (44 FR 38473); Chapter 
7, Section 4, Prevention of significant deterioration, approved by EPA 
7/28/04 (69 FR 44965)
    b. EPA Analysis:
    The State has demonstrated that it has the authority and rules in 
place to provide a process of consultation with general purpose local 
governments, designated organizations of elected officials of local 
governments and any Federal Land Manager having authority over federal 
land to which the SIP applies, consistent with the requirements of CAA 
section 121. Furthermore, EPA previously approved portions of the 
Wyoming SIP meeting the requirements of CAA section 127. (44 FR 38473, 
July 2, 1979.)
    As noted above, the State has a SIP-approved PSD program. EPA has 
further evaluated Wyoming's SIP-approved PSD program in this proposed 
action under IV.3, element 110(a)(2)(C). For the same reasons as 
discussed in subsection IV.3, EPA proposes to disapprove the Wyoming 
infrastructure SIP for the 1997 ozone NAAQS specifically for the 
requirement in section 110(a)(2)(J) that the SIP meet the applicable 
requirements of part C of title I of the Act, in particular with 
regards to the requirement that the PSD program apply to GHG sources in 
accordance with the Tailoring Rule.
    Finally, with regard to the applicable requirements for visibility 
protection, EPA recognizes that states are subject to visibility and 
regional haze program requirements under part C of the act. In the 
event of the establishment of a new NAAQS, however, the visibility and 
regional haze program requirements under part C do not change. Thus we 
find that there is no new visibility obligation ``triggered'' under 
section 110(a)(2)(J) when a new NAAQS becomes effective.
    12. Air quality and modeling/data: Section 110(a)(2)(K) requires 
that each SIP provide for (i) the performance of such air quality 
modeling as the Administrator may prescribe for the purpose of 
predicting the effect on ambient air quality of any emissions of any 
air pollutant for which the Administrator has established a NAAQS, and 
(ii) the submission, upon request, of data related to such air quality 
modeling to the Administrator.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Regulatory Documents: 1974 WAQSR, Section 21, 
Permit requirements for construction, modification and operation, 
approved by EPA on June 10, 1975 (40 FR 24726); 1979 WAQSR, Section 24, 
Prevention of significant deterioration, approved by EPA on July 2, 
1979 (44 FR 38473); Chapter 6, Section 2, Permit requirements for 
construction, modification, and operation, approved by EPA on July 28, 
2004 (69 FR 44965); Chapter 6, Section 4, Prevention of significant 
deterioration, approved by EPA on July 28, 2004 (69 FR 44965).
    b. EPA Analysis: Wyoming's SIP meets the requirements of CAA 
section 110(a)(2)(K) for the 1997 ozone NAAQS. In particular, Wyoming's 
PSD program requires that estimates of ambient air concentrations be 
based on applicable air quality models specified in Appendix W of 40 
CFR part 51, and that modification or substitution of a model specified 
in Appendix W must be approved by the Administrator. (See WAQSR Chapter 
6, section 4(b)(iv).) As a result, the SIP provides for such air 
quality modeling as the Administrator has prescribed.
    13. Permitting fees: Section 110(a)(2)(L) requires SIPs to require 
the owner or operator of each major stationary source to pay to the 
permitting authority, as a condition of any permit required under this 
act, a fee sufficient to cover (i) the reasonable costs of reviewing 
and acting upon any application for such a permit, and (ii) if the 
owner or operator receives a permit for such source, the reasonable 
costs of implementing and enforcing the terms and conditions of any 
such permit (not including any court costs or other costs associated 
with any enforcement action), until such fee requirement is superseded 
with respect to such sources by the Administrator's approval of a fee 
program under title V.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Regulatory Documents: 1993 WAQSR, Section 21, 
Permit requirements for construction, modification, and operation, 
approved by EPA on 11/29/94 (59 FR 60905); Chapter 6, Section 2, Permit 
requirements for construction, modification and operation, approved by 
EPA on July 28, 2004 (69 FR 44965).
    b. EPA Analysis: Wyoming's approved title V operating permit 
program meets the requirements of CAA section 111(a)(2)(L) for the 1997 
ozone NAAQS. Final approval of the title V operating permit program 
became effective April 23, 1999 (64 FR 8523, Feb. 22, 1990). Interim 
approval of Wyoming's title V operating permit program became effective 
February 21, 1995 (60 FR 4563, Jan. 19, 1995). As discussed in a 
previous direct final rule (which received comments) for interim 
approval of the title V program (59 FR 48802, Sept. 23, 1994), the 
State demonstrated that the fees collected were sufficient to 
administer the program.
    14. Consultation/participation by affected local entities: Section 
110(a)(2)(M) requires states to provide for consultation and 
participation in SIP development by local political subdivisions 
affected by the SIP.
    a. Wyoming's response to this requirement: Wyoming cited the 
following SIP provisions: Non-regulatory document: Intergovernmental 
Cooperation Document, approved by EPA on May 31, 1972 (37 FR 10842).
    b. EPA Analysis: Wyoming's submittal meets the requirements of CAA 
Section 110(a)(2)(M) for the 1997 ozone NAAQS.

V. What action is EPA taking?

    In this action, EPA is proposing to approve the following 
infrastructure elements for the 1997 ozone NAAQS: (A), (B), (C) with 
regards to the requirement to have a minor NSR program, (D)(ii), (E), 
(F), (G), (H), (J) with regards to the requirements related to sections 
121 and 127 of the Act, (K), (L), and (M).
    In this action, EPA also proposes approval of the State's May 11, 
2011 submission, updating the Wyoming PSD program to, among other 
things, regulate NOX as a precursor to ozone. Contingent on 
final approval of these updates, EPA is proposing to approve portions 
of infrastructure elements (C) and (J) for the 1997 ozone NAAQS with 
regards to the requirement that the State's SIP-approved PSD program 
properly regulate ozone precursors.
    In this action, EPA is proposing to disapprove the following 
infrastructure elements for the 1997 ozone NAAQS:
    (C) and (J) with regards to the requirement that the State's PSD 
program regulate GHG-emitting sources in accordance with the Tailoring 
Rule.
    In this action, EPA is taking no action on infrastructure elements 
(D)(i), (I), and (J) specifically in regard to visibility, for the 1997 
ozone NAAQS.

VI. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations (42 U.S.C. 7410(k), 40 CFR 52.02(a)).

[[Page 29686]]

Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the CAA. Accordingly, 
this proposed action merely approves some state law as meeting Federal 
requirements and disapproves other state law because it does not meet 
Federal requirements; this proposed action does not impose additional 
requirements beyond those imposed by state law. For that reason, this 
proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999); is not an 
economically significant regulatory action based on health or safety 
risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and,
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).

    In addition, this rule does not have Tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on Tribal governments or preempt Tribal law.
