52.1073—Approval status.
(a)
With the exceptions set forth in this subpart, the Administrator approves Maryland's plans for the attainment and maintenance of the national standards.
(b)
With the exceptions set forth in this subpart, the Administrator approves the amendment to Regulation 10.18.01 sections .01, .07, and .11, Regulation 10.18.04 and 10.18.05 section .03D, .03F, .03H, .06I of Maryland's plan for the attainment and maintenance of the national standards under section 110 of the Clean Air Act. Furthermore, the Administrator finds that portions of the plan, as submitted January 19, 1979, satisfy the requirements of part D, title 1, of the Clean Air Act as amended in 1977.
In addition, continued satisfaction of the requirements of Part D for the ozone portion of the SIP depends on the adoption and submittal of RACT requirements by July 1, 1980, for the sources covered by CTGs issued between January 1978 and January 1979 and adoption and submittal by each subsequent January of additional RACT requirements for sources covered by CTGs issued by the previous January.
(i)
Distributors and retailers of gasoline-ethanol blends as defined by 40 CFR 80.27(d)(2) are subject to the provisions of 40 CFR 80.27(d)(1) through 40 CFR 80.27(d)(3).
(d)
Letter of November 13, 1993, from the Maryland Department of the Environment transmitting a commitment to adopt either the Federal clean fuel fleet program or an alternative substitute program by May 15, 1994.
(h)
(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 (h), 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 (h)(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 (h)(4)(ii)(A) of this section for each gas to compute a tpy CO2 e.
(iii)
The term emissions increase shall mean that a net significant emissions increase (as defined in 40 CFR part 52.21(b)(3)(i) (2000) and the EPA-approved Maryland rules at COMAR 26.11.06.14 (state effective date 10/10/2001)). For the pollutant GHGs, a net 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 40 CFR 52.21(b)(23)(ii) (2000).
