§ 52.777 Control strategy: photochemical oxidants (hydrocarbons).
(a) The requirements of subpart G of this chapter are not met because the plan does not provide for attainment and maintenance of the national standards for photochemical oxidants (hydrocarbons) in the Metropolitan Indianapolis Intrastate Region by May 31, 1975.
(b) The requirements of subpart G are not met by Revised APC-15 (November 8, 1974 submission) because it does not provide for attainment and maintenance of the photochemical oxidant (hydrocarbon) standards throughout Indiana.
(c) Part D—Conditional approval—The 1979 Indiana plan for Clark, Floyd, Elkhart, Lake, Marion, Porter, and St. Joseph Counties is approved provided the following conditions are satisfied:
(1) The plan for stationary source volatile organic compound control must contain the following:
(i)-(iv) [Reserved]
(v) For regulation 325 IAC 8-5, Section 6, Perchloroethylene Dry Cleaning, the State must conduct a study to demonstrate that the 1,500 gallons exemption meets RACT requirements and submit the results to EPA within 6 months of the effective date of final rulemaking on 325 IAC 8 for VOC from Group II CTG source categories. If the demonstrated emissions resulting from the State's exemption are not essentially equivalent to those resulting from the RACT requirements, then the State must submit to EPA by July 1, 1983, a rule which requires control of emissions from dry cleaning sources using less than 1,500 gallons of perchloroethylene per year.
(2) The stationary source volatile organic control measures submitted by the State on October 23, 1990, and August 19, 1991, are approved as described in 40 CFR 52.770(c)(87) with the exception of 326 IAC 8-5-4 Pneumatic Rubber Tire Manufacturing, on which USEPA has taken no action. It should be noted that although the State's control measures provide that equivalent test methods, alternative emission controls, and revisions in rule applicability must be submitted to the USEPA as proposed revisions to the State Implementation Plan (SIP), such proposed SIP revisions are not part of the SIP unless and until they are approved as such by the USEPA.
(d) Part D—Disapproval. The 1982 Indiana plan for Lake and Porter County is disapproved because it does not assure the attainment and maintenance of the NAAQS there. See §§ 52.770(c)(69) and 52.773(i). The disapproval does not affect USEPA's approval (or conditional approval) of individual parts of Indiana's ozone plan and they remain approved.
(e) Approval—The Administrator approves the incorporation of the photochemical assessment ambient monitoring system submitted by Indiana on November 15, 1993, into the Indiana State Implementation Plan. This submittal satisfies 40 CFR 58.20(f), which requires the State to provide for the establishment and maintenance of photochemical assessment monitoring stations (PAMS) by November 12, 1993.
(f) Approval. The Indiana Department of Environmental Management submitted two ozone redesignation requests and maintenance plans requesting the ozone nonattainment areas to be redesignated to attainment for ozone: South Bend/Elkhart (St. Joseph and Elkhart Counties), submitted on September 22, 1993; Indianapolis (Marion County), submitted on November 12, 1993. The redesignation requests and maintenance plans meet the redesignation requirements in section 107(d)(3)(d) of the Act as amended in 1990. The redesignations meet the Federal requirements of section 182(a)(1) of the Clean Air Act as a revision to the Indiana Ozone State Implementation Plan for the above mentioned counties.
(g) The base year ozone precursor emission inventory requirement of section 182(a)(1) of the Clean Air Act, as amended in 1990, has been satisfied for the following areas: Vanderburgh County in the Evansville Metropolitan Area; Marion County in the Indianapolis Metropolitan Area; and St. Joseph and Elkhart Counties in the South Bend Metropolitan Area.
(h) On November 17, 1993, Indiana submitted two of three elements required by section 182(d)(1)(A) of the Clean Air Amendments of 1990 to be incorporated as part of the vehicle miles traveled (VMT) State Implementation Plan intended to offset any growth in emissions from a growth in vehicle miles traveled. These elements are the offsetting of growth in emissions attributable to growth in VMT which was due November 15, 1992, and, any transportation control measures (TCMs) required as part of Indiana's 15 percent reasonable further progress (RFP) plan which was due November 15, 1993. Indiana satisfied the first requirement by projecting emissions from mobile sources and demonstrating that no increase in emissions would take place. Indiana satisfied the second requirement by determining that no TCMs were required as part of Indiana's 15 percent RFP plan.
(i) Approval—EPA is approving the section 182(f) oxides of nitrogen (NOX) reasonably available control technology (RACT), new source review (NSR), vehicle inspection/maintenance (I/M), and general conformity exemptions for the Indiana portion of the Chicago-Gary-Lake County severe ozone nonattainment area as requested by the States of Illinois, Indiana, Michigan, and Wisconsin in a July 13, 1994 submittal. This approval does not cover the exemption of NOX transportation conformity requirements of section 176(c) for this area. Approval of these exemptions is contingent on the results of the final ozone attainment demonstration expected to be submitted in mid-1997. The approval will be modified if the final attainment demonstration demonstrates that NOX emission controls are needed in the nonattainment area to attain the ozone standard in the Lake Michigan Ozone Study modeling domain.
(j) The base year ozone precursor emission inventory requirement of section 182(a)(1) of the Clean Air Act, as amended in 1990, has been satisfied for Lake and Porter Counties, Indiana.
(k) On June 26, 1995, and June 13, 1997, Indiana submitted a 15 percent rate-of-progress plan for the Lake and Porter Counties portion of the Chicago-Gary-Lake County ozone nonattainment area. This plan satisfies the counties' requirements under section 182(b)(1) of the Clean Air Act, as amended in 1990.
(l) [Reserved]
(m) On July 12, 1995, Indiana submitted a 15 percent rate-of-progress plan for the Clark and Floyd Counties portion of the Louisville ozone nonattainment area. This plan satisfies Clark and Floyd Counties' requirements under section 182(b) of the Clean Air Act, as amended in 1990.
