Section R307-405-3


Notice of Proposed Rule


DAR File No.: 39846
Filed: 10/15/2015 03:32:56 PM


Purpose of the rule or reason for the change:

Due to EPA's good cause final rule to remove portions of its PSD and title V permitting regulations, the Division of Air Quality is proposing changes to Section R307-405-3. These changes will align Utah's rules with EPA's regulations.

Summary of the rule or change:

This rule removes the greenhouse gas tailoring rule that regulated new and existing stationary sources.

State statutory or constitutional authorization for this rule:

  • Section 19-2-104

Anticipated cost or savings to:

the state budget:

This amendment will save the state budget any costs associated with enforcement and compliance with the greenhouse gas tailoring rule.

local governments:

This amendment will not likely affect local governments because the rule would have been administered at the state level.

small businesses:

This amendment will not likely affect small businesses because most small businesses were not regulated under the rule.

persons other than small businesses, businesses, or local governmental entities:

Other persons will not likely be affected by this rule. The rule was mainly regulating businesses and government entities. Any other persons affected will likely save money as a result of the rule because the rule is repealing the requirement that some greenhouse gas sources are regulated.

Compliance costs for affected persons:

Affected persons will save money regarding compliance because they will no longer have to comply with the greenhouse gas tailoring rule.

Comments by the department head on the fiscal impact the rule may have on businesses:

This rule will likely have a positive fiscal impact on businesses. Large businesses that were regulated under this rule will no longer incur any costs associated with compliance. Most small businesses will not see an impact because they were not regulated under this rule before the amendment.

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:

(G) 40 CFR 52.21(p)(2), and

(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),

(iv) the definition of "fixed capital cost" in 40 CFR 52.21 (b)(57), and

(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[s] (d) [through (e)]of this section.

(b) For purposes of paragraphs (c) through ([e]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[s] (d) [through (e)]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[; and,

(e) Beginning July 1, 2011, in addition to the provisions in paragraph (d) of this section, the pollutant GHGs shall also be subject to regulation:

(i) At a new stationary source that will emit or have the potential to emit 100,000 tpy CO2e; or

(ii) At an existing stationary source that emits or has the potential to emit 100,000 tpy CO2e, 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 CO2e or more].
