52.773—Approval status.
(a)
With the exceptions set forth in this subpart, the Administrator approves Indiana's plan for attainment and maintenance of the National Ambient Air Quality Standards under section 110 of the Clean Air Act.
(c)
The Administrator finds that Indiana's new source review strategy satisfies all requirements of Part D, Title 1 of the Clean Air Act as amended in 1977.
(f)
The Administrator finds ozone strategies for Clark, Elkhart, Floyd, Lake, Marion, Porter, and St. Joseph Counties satisfy all requirements of Part D, Title I of the Clean Air Act that are required to be submitted by January 1, 1981, except as noted below.
(g)
The administrator finds that the total suspended particulate strategies for Clark, Dearborn, Dubois, St. Joseph, Vanderburgh, and Vigo Counties satisfy all the requirements of Part D, Title I of the Clean Air Act except as noted below.
(h)
The Administrator finds that the SO2 strategies for Lake, LaPorte, Marion, Vigo, and Wayne Counties satisfy all requirements of Part D, Title 1 of the Clean Air Act, as amended in 1977. See § 52.770 (c)(67) and (c)(72).
(i)
The Administrator finds that Indiana's ozone plan for Lake and Porter Counties, which was required to be submitted by July 1, 1992, does not satisfy all the requirements of part D, title 1 of the Clean Air Act and, thus, is disapproved. See §§ 52.770(c)(69) and 52.770(d). The disapproval does not affect USEPA's approval (or conditional approval) of individual parts of Indiana's ozone plan and they remain approved.
(j)
The Administrator finds that the following portions of Indiana's ozone and CO plans satisfy the related requirements of part D, title 1 of the Clean Air Act, as amended in 1977:
(1)
The transportation control plans for Lake, Porter, Clark and Floyd Counties, submitted on May 14, 1986, June 10, 1986, and April 6, 1987.
(2)
The vehicle inspection and maintenance plan for Clark, Floyd, Lake, and Porter Counties, submitted October 27, 1989, and January l9, 1990.
(3)
The demonstration of attainment, submitted December 2, 1983, and the carbon monoxide plan as a whole for the designated nonattainment area in Lake County.
(k)
(1)
Insofar as the Prevention of Significant Deterioration (PSD) provisions found in this subpart apply to stationary sources of greenhouse gas (GHGs) emissions, the Administrator approves that application only to the extent that GHGs are “subject to regulation”, as provided in this paragraph (k), and the Administrator takes no action on that application to the extent that GHGs are not “subject to regulation.”
(i)
The stationary source is a new major stationary source for a regulated NSR pollutant that is not GHGs, and also will emit or will have the potential to emit 75,000 tpy CO2 e or more; or
(ii)
The stationary source is an existing major stationary source for a regulated NSR pollutant that is not GHGs, and also will have an emissions increase of a regulated NSR pollutant, and an emissions increase of 75,000 tpy CO2 e or more; and,
(3)
Beginning July 1, 2011, in addition to the provisions in paragraph (k)(2) of this section, the pollutant GHGs shall also be subject to regulation:
(ii)
At an existing stationary source that emits or has the potential to emit 100,000 tpy CO2 e, when such stationary source undertakes a physical change or change in the method of operation that will result in an emissions increase of 75,000 tpy CO2 e or more.
(i)
The term greenhouse gas shall mean the air pollutant defined in 40 CFR 86.1818-12(a) as the aggregate group of six greenhouse gases: Carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
(ii)
The term tpy CO2 equivalent emissions (CO2 e) shall represent an amount of GHGs emitted, and shall be computed as follows:
(A)
Multiplying the mass amount of emissions (tpy), for each of the six greenhouse gases in the pollutant GHGs, by the gas's associated global warming potential published at Table A-1 to subpart A of 40 CFR part 98 —Global Warming Potentials.
(B)
Sum the resultant value from paragraph (k)(4)(ii)(A) of this section for each gas to compute a tpy CO2 e.
(iii)
The term emissions increase shall mean that both a significant emissions increase (as calculated using the procedures in [326 IAC-2-2-2(d) of Indiana's Administrative Code) and a significant net emissions increase (as defined in 326 IAC-2-1, paragraphs (ii) and (ww) of Indiana's Administrative Code) occur. For the pollutant GHGs, an emissions increase shall be based on tpy CO2 e, and shall be calculated assuming the pollutant GHGs is a regulated NSR pollutant, and “significant” is defined as 75,000 tpy CO2 e instead of applying the value in paragraph 326 IAC 2-2-1(ww)(1)(V) of Indiana's Administrative Code.
