R307-405.  Permits:  Major Sources in Attainment or Unclassified Areas (PSD).
R307-405-1.  Purpose.
	This rule implements the federal Prevention of Significant Deterioration (PSD) permitting program for major sources and major modifications in attainment areas and maintenance areas as required by 40 CFR 51.166.  This rule does not include the routine maintenance, repair and replacement provisions that were vacated by the DC Circuit Court of Appeals on March 17, 2006.  This rule supplements, but does not replace, the permitting requirements of R307-401.

R307-405-2.  Applicability.
	(1)  All references to 40 CFR in R307-405 shall mean the version that is in effect on July 1, 2018.
	(2)  The provisions of 40 CFR 52.21(a)(2) are hereby incorporated by reference.
	(3)  Notwithstanding the exemptions in R307-401, any source that is subject to R307-405 is subject to the requirement to obtain an approval order in R307-401-5 through 8.

R307-405-3.  Definitions.
	(1)  Except as provided in (2) and (9) below, the definitions contained in 40 CFR 52.21(b) are hereby incorporated by reference.
	(2)(a)  In the definition of "baseline area" in 40 CFR 52.21(b)(15)(ii)(b) insert the words "or R307-405" after "Is subject to 40 CFR 52.21".
	(b)  "Reviewing Authority" means the director.
	(c)(i)  The term "Administrator" shall be changed to "director" throughout R307-405, except as provided in (ii).
	(ii)  The term "Administrator" shall be changed to "EPA Administrator" in the following incorporated sections:
	(A)  40 CFR 52.21(b)(17),

	(H)  40 CFR 51.166(q)(2)(iv).
	(d)  The following definitions or portions of definitions that apply to the equipment repair and replacement provisions are not incorporated because these provisions were vacated by the DC Circuit Court of Appeals on March 17, 2006:
	(i)  in the definition major modification in 40 CFR 52.21(b)(2), the second sentence in subparagraph (iii)(a),
	(ii)  the definition of "process unit" in 40 CFR 52.21(b)(55),
	(iii)  the definition of "functionally equivalent component" in 40 CFR 52.21(b)(56),

	(v)  the definition of "total capital investment" in 40 CFR 52.21(b)(58).
	(e)  In the definition of "Regulated NSR pollutant" in 40 CFR 52.21(b)(50), subparagraph (iv) shall be changed to read, "Any pollutant that otherwise is subject to regulation under the Act."  A new subparagraph (v) shall be added that reads, "The term regulated NSR pollutant shall not include any or all hazardous air pollutants either listed in section 112 of the federal Clean Air Act, or added to the list pursuant to section 112(b)(2) of the federal Clean Air Act, and which have not been delisted pursuant to section 112(b)(3) of the federal Clean Air Act, unless the listed hazardous air pollutant is also regulated as a constituent or precursor of a general pollutant listed under section 108 of the federal Clean Air Act."
	(3)  "Air Quality Related Values," as used in analyses under 40 CFR 52.21 (p) that is incorporated by reference in R307-405-17, means those special attributes of a Class I area, assigned by a federal land manager, that are adversely affected by air quality.
	(4)  "Heat input" means heat input as defined in 40 CFR 52.01(g), that is hereby incorporated by reference.
	(5)  "Title V permit" means any permit or group of permits covering a Part 70 source that is issued, renewed, amended, or revised pursuant to R307-415.
	(6)  "Title V Operating Permit Program" means R307-415.
	(7)  The definition of "Good Engineering Practice (GEP) Stack Height" as defined in R307-410 shall apply in this rule.
	(8)  The definition of "Dispersion Technique" as defined in R307-410 shall apply in this rule.
	(9)  "Subject to regulation" means, for any air pollutant, that the pollutant is subject to either a provision in the federal Clean Air Act, or a nationally-applicable regulation codified by the Administrator in subchapter C of 40 CFR Chapter I, that requires actual control of the quantity of emissions of that pollutant, and that such a control requirement has taken effect and is operative to control, limit or restrict the quantity of emissions of that pollutant released from the regulated activity. Except that:
	(a)  "Greenhouse gases (GHGs)," the air pollutant defined in 40 CFR 86.1818-12(a) (Federal Register, Vol. 75, Page 25686) as the aggregate group of six greenhouse gases: carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride, shall not be subject to regulation except as provided in paragraph (d) of this section.
	(b)  For purposes of paragraphs (c) through (d) of this section, the term "tons per year (tpy) CO2 equivalent emissions (CO2e)" shall represent an amount of GHGs emitted, and shall be computed as follows:
	(i)  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, that is hereby incorporated by reference (Federal Register, Vol. 74, Pages 56395-96).
	(ii)  Sum the resultant value from paragraph (b)(i) of this section for each gas to compute a tpy CO2e.
	(c)  The term "emissions increase" as used in paragraph (d) of this section shall mean that both a significant emissions increase (as calculated using the procedures in 40 CFR 52.21 (a)(2)(iv) that is incorporated by reference in R307-405-2) and a significant net emissions increase (as defined in paragraphs 40 CFR 52.21(b)(3) and (b)(23) that is incorporated by reference in R307-405-3) occur. For the pollutant GHGs, an emissions increase shall be based on tpy CO2e, and shall be calculated assuming the pollutant GHGs is a regulated NSR pollutant, and ''significant'' is defined as 75,000 tpy CO2e instead of applying the value in paragraph 40 CFR 52.21(b)(23)(ii).
	(d)  Beginning January 2, 2011, the pollutant GHGs is subject to regulation if:
	(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 CO2e 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 CO2e or more.

R307-405-8.  Exclusions from Increment Consumption.
	(1)  The following concentrations shall be excluded in determining compliance with a maximum allowable increase:
	(a)  concentrations attributable to the increase in emissions from stationary sources which have converted from the use of petroleum products, natural gas, or both by reason of an order in effect under section 2(a) and (b) of the Energy Supply and Environmental Coordination Act of 1974 (or any superseding legislation) over the emissions from such sources before the effective date of such an order;
	(b)  concentrations attributable to the increase in emissions from sources which have converted from using natural gas by reason of a natural gas curtailment plan in effect pursuant to the Federal Power Act over the emissions from such sources before the effective date of such plan;
	(c)  concentrations of particulate matter attributable to the increase in emissions from construction or other temporary emission-related activities of new or modified sources;
	(d)  the increase in concentrations attributable to new sources outside the United States over the concentrations attributable to existing sources which are included in the baseline concentration; and
	(e)  concentrations attributable to the temporary increase in emissions of sulfur dioxide, particulate matter, or nitrogen dioxides from stationary sources which are affected by plan revisions approved by the EPA Administrator as meeting the criteria specified in 40 CFR 51.166(f)(4).  The temporary increase shall not exceed 2 years in duration unless a longer time is approved by the EPA Administrator.  This exclusion is not renewable.
	(2)  No exclusion of concentration under (1)(a) or (b) above shall apply more than five years after the effective date of the order to which paragraph (1)(a) refers or the plan to which paragraph (1)(b) refers, whichever is applicable.  If both such order and plan are applicable, no such exclusion shall apply more than five years after the later of such effective dates.
	(3)  No exclusion under (1)(e) shall apply to an emission increase from a stationary source which would:
	(a)  impact a Class I area or an area where an applicable increment is known to be violated; or
	(b)  cause or contribute to a violation of the national ambient air quality standards.
