RULE ANALYSIS

Purpose of the rule or reason for the change:

The Environmental Protection Agency (EPA) has identified a number of issues with Utah's permitting rule for new or modified sources in nonattainment areas (Rule R307-403) that affected their ability to approve Utah's PM10 Maintenance Plan. These same issues will potentially affect EPA's approval of the PM2.5 State Implementation Plan (SIP). In addition, there have been a number of changes to the federal regulations, most notably NSR Reform and the PM2.5 implementation rule for new source review, that have not yet been incorporated into Utah's rule.

Summary of the rule or change:

The title of the section is changed from "Emission Limitations" to "Applicability." Language is added to this section of the rule to mirror language of the Federal Code of Regulations. The language from Section R307-401-20 is moved from Rule R307-401 to Rule R307-403 as Subsection R307-403-2(5)(b). (DAR NOTE: The proposed amendment to R307-401-20 is under DAR No. 37269 in this issue, March 1, 2013, of the Bulletin.)

State statutory or constitutional authorization for this rule:

• Section 19-2-108
• Section 19-2-104

This rule or change incorporates by reference the following material:

• Adds 40 CFR Part 51, published by National Archives and Records Administration's Office of the Federal Register, 07/01/2012

Anticipated cost or savings to:

the state budget:

There are no new requirements to the state; therefore, there are no anticipated costs or savings to the state budget.

local governments:

There are no new requirements to local governments; therefore, there are no anticipated costs or savings associated with this rule.

small businesses:

This rule applies primarily to major sources. There are no changes to provisions that would apply to small businesses; therefore, there are no costs or savings to small business.

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

There are no new requirements for persons other than small businesses, businesses, or local government entities; therefore, there are no anticipated costs or savings.

Compliance costs for affected persons:

This rule incorporates EPA's NSR reform provisions that provide additional flexibility for major sources in nonattainment areas. This additional flexibility will provide cost savings for major sources. In addition, the applicability provisions will more closely match related provisions in Rule R307-405 that apply to attainment areas, simplifying the permitting process for major sources.

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

This rule incorporates EPA's NSR reform provisions that provide additional flexibility for major sources in nonattainment areas. This additional flexibility will provide cost savings for major sources. In addition, the applicability provisions will more closely match related provisions in Rule R307-405 that apply to attainment areas, simplifying the permitting process for major sources.

R307-403. Permits: New and Modified Sources in Nonattainment Areas and Maintenance Areas.

R307-403-2. [Emission Limitations]Applicability.

[Any source constructed in an actual area of nonattainment, or in the Salt Lake City and Ogden maintenance areas for carbon monoxide, or in an area which will impact on an actual area of nonattainment or on the Salt Lake City and Ogden maintenance areas for carbon monoxide must meet all applicable emission requirements of R307 and the State Implementation Plan incorporated by reference under R307-110. A proposed source which is not a major source may be approved without further analysis provided such source meets all such applicable emission limitations and offset requirements in R307-403-4, 5, and 6. The emission limitations shall be stated as a condition of the approval order.

] (1) R307-403 applies to any new major stationary source or major modification that is major for the pollutant for which the area is designated nonattainment under section 107(d)(1)(A)(i) of the Act, if the stationary source or modification would locate anywhere in the designated nonattainment area.

(a) Except as otherwise provided in paragraph R307-403(2), and consistent with the definition of major modification contained in 40 CFR 51.165(a)(1)(v)(A), a project is a major modification for a regulated NSR pollutant if it causes two types of emissions increases--a significant emissions increase (as defined in 40 CFR 51.165(a)(1)(xxvii)), and a significant net emissions increase (as defined in 40 CFR 51.165(a)(1)(vi) and (x)). The project is not a major modification if it does not cause a significant emissions increase. If the project causes a significant emissions increase, then the project is a major modification only if it also results in a significant net emissions increase.

(b) The procedure for calculating (before beginning actual construction) whether a significant emissions increase (i.e., the first step of the process) will occur depends upon the type of emissions units being modified, according to paragraphs R307-403-2(c) through (e). The procedure for calculating (before beginning actual construction) whether a significant net emissions increase will occur at the major stationary source (i.e., the second step of the process) is contained in the definition in 40 CFR 51.165(a)(1)(vi). Regardless of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase.

(c) Actual-to-projected-actual applicability test for projects that only involve existing emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the projected actual emissions (as defined in 40 CFR 51.165(a)(1)(xxviii)) and the baseline actual emissions (as defined in 40 CFR 51.165(a)(1)(xxxv)(A) and (B), as applicable), for each existing emissions unit, equals or exceeds the significant amount for that pollutant (as defined in 40 CFR 51.165(a)(1)(x)).

(d) Actual-to-potential test for projects that only involve construction of a new emissions unit(s). A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit (as defined in 40 CFR 51.165(a)(1)(iii)) from each new emissions unit following completion of the project and the baseline actual emissions (as defined in 40 CFR 51.165(a)(1)(xxxv)(C)) of these units before the project equals or exceeds the significant amount for that pollutant (as defined in 40 CFR 51.165(a)(1)(x)).

(e) Reserved.

(f) Hybrid test for projects that involve multiple types of emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases for each emissions unit, using the method specified in R307-403-2(1)(C) through (D) as applicable with respect to each emissions unit, for each type of emissions unit equals or exceeds the significant amount for that pollutant (as defined in 40 CFR 51.165(a)(1)(x)).

(2) For any major stationary source for a PAL for a regulated NSR pollutant, the major stationary source shall comply with requirements under R307-403-11.

(3) Reserved.

(4) R307-403 does not apply to any source or modification that would be a major source or major modification only if fugitive emissions to the extent quantifiable are considered in calculating the potential to emit of the stationary source or modification and the source does not belong to any of the categories listed in R307-403-2(4)(a) through (aa).

(a) Coal cleaning plants (with thermal dryers);

(b) Kraft pulp mills;

(c) Portland cement plants;

(d) Primary zinc smelters;

(e) Iron and steel mills;

(f) Primary aluminum ore reduction plants;

(g) Primary copper smelters;

(h) Municipal incinerators capable of charging more than 250 tons of refuse per day;

(i) Hydrofluoric, sulfuric, or citric acid plants;

(j) Petroleum refineries;

(k) Lime plants;

(l) Phosphate rock processing plants;

(m) Coke oven batteries;

(n) Sulfur recovery plants;

(o) Carbon black plants (furnace process);

(p) Primary lead smelters;

(q) Fuel conversion plants;

(r) Sintering plants;

(s) Secondary metal production plants;

(t) Chemical process plants--The term chemical processing plant shall not include ethanol production facilities that produce ethanol by natural fermentation included in NAICS codes 325193 or 312140;

(u) Fossil-fuel boilers (or combination thereof) totaling more than 250 million British thermal units per hour heat input;

(v) Petroleum storage and transfer units with a total storage capacity exceeding 300,000 barrels;

(w) Taconite ore processing plants;

(x) Glass fiber processing plants;

(y) Charcoal production plants;

(z) Fossil fuel-fired steam electric plants of more than 250 million British thermal units per hour heat input;

(aa) Any other stationary source category which, as of August 7, 1980, is being regulated under section 111 or 112 of the Act.

(5)(a) Approval to construct shall not relieve any owner or operator of the responsibility to comply fully with applicable provision of the state implementation plan and any other requirements under local, state or federal law.

(b) At such time that a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in any enforcement limitation which was established after August 7, 1980, on the capacity of the source or modification otherwise to emit a pollutant, such as a restriction on hours of operation, then the requirements of regulations approved pursuant to this section shall apply to the source or modification as though construction had not yet commenced on the source or modification;

(6) The provisions of R307-403-2(6)(a) through (f) apply to projects at existing emissions units at a major stationary source (other than projects at a source with a PAL) in circumstances where there is a reasonable possibility that a project that is not a part of a major modification may result in a significant emissions increase and the owner or operator elects to use the method specified in paragraphs 40 CFR 51.165(a)(1)(xxviii)(B)(1) through (3) for calculating projected actual emissions.

(a) Before beginning actual construction of the project, the owner or operator shall document and maintain a record of the following information:

(i) A description of the project;

(ii) Identification of the emissions unit(s) whose emissions of a regulated NSR pollutant could be affected by the project; and

(iii) A description of the applicability test used to determine that the project is not a major modification for any regulated NSR pollutant, including the baseline actual emissions, the projected actual emissions, the amount of emissions excluded under 40 CFR 51.165(a)(1)(xxviii)(B)(3) and an explanation for why such amount was excluded, and any netting calculations, if applicable.

(b) If the emissions unit is an existing electric utility steam generating unit, before beginning actual construction, the owner or operator shall provide a copy of the information set out in R307-403-2(6)(a) to the reviewing authority. Nothing in this paragraph shall be construed to require the owner or operator of such a unit to obtain any determination from the reviewing authority before beginning actual construction.

(c) The owner or operator shall monitor the emissions of any regulated NSR pollutant that could increase as a result of the project and that is emitted by any emissions units identified in paragraph R307-403-2(6)(a)(ii); and calculate and maintain a record of the annual emissions, in tons per year on a calendar year basis, for a period of 5 years following resumption of regular operations after the change, or for a period of 10 years following resumption of regular operations after the change if the project increases the design capacity or potential to emit of that regulated NSR pollutant at such emissions unit.

(d) If the unit is an existing electric utility steam generating unit, the owner or operator shall submit a report to the reviewing authority within 60 days after the end of each year during which records must be generated under paragraph R307-403-2(6)(c) setting out the unit's annual emissions during the year that preceded submission of the report.

(e) If the unit is an existing unit other than an electric utility steam generating unit, the owner or operator shall submit a report to the reviewing authority if the annual emissions, in tons per year, from the project identified in paragraph R307-403-2(6)(a), exceed the baseline actual emissions (as documented and maintained pursuant to paragraph R307-403-2(6)(c), by a significant amount (as defined in 40 CFR 51.165(a)(1)(x)) for that regulated NSR pollutant, and if such emissions differ from the preconstruction projection as documented and maintained pursuant to paragraph R307-403-2(6)(c). Such report shall be submitted to the reviewing authority within 60 days after the end of such year. The report shall contain the following:

(i) The name, address and telephone number of the major stationary source;

(ii) The annual emissions as calculated pursuant to paragraph R307-403-2(6)(c); and

(iii) Any other information that the owner or operator wishes to include in the report (e.g., an explanation as to why the emissions differ from the preconstruction projection).

(f) A "reasonable possibility" under (R307-403-2(6) occurs when the owner or operator calculates the project to result in either:

(i) A projected actual emissions increase of at least 50 percent of the amount that is a "significant emissions increase," as defined in 40 CFR 51.165(a)(1)(xxvii)(without reference to the amount that is a significant net emissions increase), for the regulated NSR pollutant; or

(ii) A projected actual emissions increase that, added to the amount of emissions excluded under 40 CFR 51.165(a)(1)(xxviii)(B)(3), sums to at least 50 percent of the amount that is a "significant emissions increase," as defined under paragraph 40 CFR 51.165(a)(1)(xxvii) without reference to the amount that is a significant net emissions increase), for the regulated NSR pollutant. For a project for which a reasonable possibility occurs only within the meaning of this paragraph, and not also within the meaning of paragraph R307-403-2(6)(f)(i), then provisions R307-403-2(6)(b) through (e) do not apply to the project.

(7) The owner or operator of the source shall make the information required to be documented and maintained pursuant to paragraph R307-403-2(6) above available for review upon a request for inspection by the director or the general public pursuant to the requirements contained in 40 CFR 70.4(b)(3)(viii).

(8) The requirements of R307-403 applicable to major stationary sources and major modifications of volatile organic compounds shall apply to nitrogen oxides emissions from major stationary sources and major modifications of nitrogen oxides in an ozone transport region or in any ozone nonattainment area, except in ozone nonattainment areas or in portions of an ozone transport region where the EPA Administrator has granted a nitrogen oxides waiver applying the standards set forth under section 182(f) of the Clean Air Act and the waiver continues to apply.

(9) Reserved.

(10) The requirements of R307-403 applicable to major stationary sources and major modifications of PM ₁₀ shall also apply to major stationary sources and major modifications of PM ₁₀ precursors, except where the Administrator determines that such sources do not contribute significantly to PM ₁₀ levels that exceed the PM ₁₀ ambient standards in the area.

(11) Reserved.

(12) R307-403 applies to any major source or major modification that is located outside a nonattainment area and is major for the pollutant for which the area is designated nonattainment under section 107(d)(1)(A)(i) of the Clean Air Act and that causes the significant increments in R307-403-3(1) to be exceeded in the nonattainment area.

(12) R307-403-5 applies to any new or modified source in a PM ₁₀ nonattainment area.
