THE PROPOSED AMENDMENTS TO THE RULES OF THE

DEPARTMENT OF NATURAL RESOURCES

ENVIRONMENTAL PROTECTION DIVISION

RELATING TO AIR QUAL ITY, CHAPTER 391-3-1

Rule 391-3-1-.02(7), “Prevention of Significant Deterioration of Air Quality,” is being

amended.

Purpose: This rule is being revised to incorporate Prevention of Significant Deterioration (PSD) provisions for fine particulate matter, as promulgated by U.S. EPA on May 16, 2008; the Greenhouse Gas Tailoring Rule, as promulgated by U.S. EPA on June 3, 2010; and various minor changes necessary to reflect revisions made by U.S., EPA and federal court decisions over the past several years. This rule is also being revised to include the effective date of the provisions of 40 CFR Part 52.21 where they are incorporated by reference.

Main Features: Amendment dates have been added to all provisions that incorporate portions of the federal rule into the Georgia rule by reference. Changes that incorporate the PSD provisions for fine particulate matter are included in subparagraph 391-3-1-.02(7)(a)2., “Definitions” and subparagraph 391-3-1-.02(7)(b)6., “Exemptions.” Changes that incorporate the Greenhouse Gas Tailoring Rule are included in subparagraph 391-3-1-.02(7)(a)2., “Definitions.” Due to the legal and political uncertainty regarding the Greenhouse Gas Tailoring Rule provisions, language has been included in the rule to make clear that regulation of greenhouse gases under the PSD permitting program in Georgia shall cease if it ceases at the federal level.

Rule 391-3-1-.03(10), “Title V Operating Permits ,” is being amended.

Purpose: This rule is being revised to incorporate the Greenhouse Gas Tailoring Rule, as promulgated by U.S. EPA on June 3, 2010. This rule is also being revised to include effective dates of the provisions of 40 CFR Part 70 where they are incorporated by reference.

The revision to 391-3-1-.03(10)(a)4. incorporates the requirements of the Greenhouse Gas Tailoring Rule, which are located in 40 CFR Part 70.2. Due to the legal and political uncertainty regarding the Greenhouse Gas Tailoring Rule provisions, language has been included in the rule to make clear that regulation of greenhouse gases under the Title V permitting program in Georgia shall cease if it ceases at the federal level.Chapter 391-3-1 Rules for Air Quality Control



### STATEMENT OF RATIONALE

Rules for Air Quality Control

Rule 391-3-1-.02(7) Prevention of Significant Deterioration of Air Quality

The purpose of this revision is to reference the most recent version of 40 CFR Part 52.21 which includes revisions to Part 52.21(b) to incorporate the federal Greenhouse Gas Tailoring Rule and revisions to Part 52.21(b) and (i) to incorporate the federal Prevention of Significant Deterioration (PSD) provisions for fine particulate matter.

This revision is administrative in nature and is in no way any more restrictive than the federal requirements. Certain segments of the regulated industry will incur permitting requirements for greenhouse gases and fine particulate matter. The main element of this rule revision is the incorporation of the federal Greenhouse Gas Tailoring Rule emission thresholds for greenhouse gases. This rule revision is necessary due to actions taken by the federal government that triggered the requirements to regulate greenhouse gas emissions from stationary sources.

On December 15, 2009, U.S. EPA published in the Federal Register (74 FR 66496) their final action on two distinct findings regarding greenhouse gases under Section 202(a) of the Clean Air Act. In the “Endangerment Finding,” U.S. EPA found that elevated concentrations of six greenhouse gases constitute air pollution endangering public health and welfare. In the “Cause or Contribute Finding,” U.S. EPA found that four of these greenhouse gases that are emitted by new light-duty motor vehicles cause or contribute to this air pollution. According to U.S. EPA, these findings required them to adopt greenhouse gas emissions regulations for new light-duty

motor vehicles.

On May 7, 2010, U.S. EPA published in the Federal Register (75 FR 25324) their final rule regulating greenhouse gas emissions from new light-duty motor vehicles. In a separate action, U.S. EPA stated that this standard takes effect on January 2, 2011. According to U.S. EPA, the national regulation of greenhouse gas emissions from light-duty vehicles makes greenhouse gases regulated air pollutants under the PSD and Title V permit programs. Therefore, greenhouse gases will become subject to regulation at stationary sources as of January 2,

2011.

Because U.S. EPA interpreted the Clean Air Act such that the Endangerment Finding required them to adopt greenhouse gas regulations on light-duty vehicles and because they interpreted the Clean Air Act such that the stationary source permitting requirements are automatically triggered as a matter of law once the light-duty vehicle rule takes effect, U.S. EPA did not calculate the cost to regulated industry or to the state permitting authorities as a result of those requirements being triggered when U.S. EPA finalized the light-duty vehicle rule. As discussed further below, U.S. EPA did calculate the amount of regulatory costs avoided as a result of the Greenhouse Gas Tailoring Rule. Therefore, this information can be used to approximate the total impact to the regulated industry and state permitting authorities as a result of the Endangerment Finding and the light-duty vehicle rule as well as the additional costs that remain upon the regulated industry and state permitting authorities after the Greenhouse Gas Tailoring Rule thresholds are implemented.Chapter 391-3-1 Rules for Air Quality Control

The Clean Air Act states that the applicability threshold for PSD permits is 100 or 250 (depending upon the source type) tons per year and that the applicability threshold for Title V permits is 100 tons per year. These thresholds work for traditional air pollutants such as sulfur dioxide or particulate matter. However, greenhouse gas emissions such as carbon dioxide are emitted in much higher quantities than sulfur dioxide or particulate matter. Therefore, according to U.S. EPA, about six million additional sources nationally would be subject to the Title V permitting program (currently there are about 15,000 sources under this program nationally) and about 20,000 additional sources nationally would be subject to the PSD permitting program (currently there are about 280 such projects annually in the nation) at a cost of about $55 billion to the regulated industry and $22 billion to state permitting authorities.

In order to avoid regulatory gridlock created by the submission of more applications than the regulatory agency could possibly handle, as well as the imposition of costly permitting requirements on very small sources, U.S. EPA adopted the Greenhouse Gas Tailoring Rule. This final rule was published in the Federal Register on June 3, 2010 (75 FR 31514). This rule raises the permitting thresholds for greenhouse gases by adopting a definition for the previously undefined term “subject to regulation” which states that greenhouse gas emissions are not “subject to regulation” below the thresholds in the rule.

The thresholds are phased in over time in tw o steps. In addition, U.S. EPA has committed to continue to evaluate the appropriateness of these thresholds and may go through rulemaking in the future, effective no earlier than 2013, to lower the thresholds closer to the statutory levels.

During Step 1, which would go from January 2, 2011, until July 1, 2011, sources subject to PSD “anyway” will be required to install Best Available Control Technology for greenhouse gases if the project increases emissions by 75,000 tons per year or more.

During Step 2, which would begin on July 1, 2011 and continue until U.S. EPA finalizes additional rulemaking revising these thresholds, new sources with greenhouse gases of 100,000 tons per year or more and existing sources that increase emissions by 75,000 tons per year or more would be subject to PSD. New Title V source s must submit applications within 1 year of becoming a major source. Therefore, the application deadline would be July 1, 2012, for 100,000 ton-per-year existing sources that are not currently Title V sources and one year after commencement of operation for new major Title V sources.

With the Tailoring rule thresholds in place, the combined impact of the PSD and Title V permitting requirements to state permitting authorit ies drops down to $36 million nationally. This amount reflects a 42% increase in cost (direct costs only) over the current program. In addition to the direct administrative burdens calculated by U.S. EPA, permitting authorities will incur other burdens, including significant support and outreach activities by permitting and public affairs staff for the many newly regulated sources as well as increased compliance activity by state environmental agencies. The remaining impact to regulated industry was more difficult to

calculate because U.S. EPA did not calculate it directly. However, U.S. EPA’s estimated administrative costs to industry are approximately 2.5 times greater than the administrative costs to the state permitting authorities. Therefore, the additional cost to industry, with the Tailoring rule thresholds in place, are approximately $90 million nationally (this does not include the cost of additional air pollution controls or additional compliance costs). As described above, the costs without the Tailoring rule on regulated industry and state permitting authorities are $55 billion and $22 billion, respectively.Chapter 391-3-1 Rules for Air Quality Control

U.S. EPA has stated that they will conduct additional rulemakings to evaluate the feasibility of lowering these thresholds further. However, EPA has stated that the earliest that these lower thresholds would be implemented is July 1, 2013, and in the absence of completed rulemaking the thresholds in Step 2 will remain in effect.

The U.S. EPA has put Georgia EPD, and other state permitting authorities, in a very difficult situation. The light-duty vehicle rule automatically triggered the regulation of greenhouse gases at stationary sources. Therefore, at this point, there are three basic paths that this situation

could take.

1. If a state takes action to prohibit the regulation of greenhouse gases within the state, U.S. EPA will take over the permitting program for greenhouse gases from the state (and has already proposed to do so for about a dozen states). In the meantime, regulatory gridlock and uncertainty will likely occur. Once U.S. EPA begins to implement the permitting program, it will likely take much l onger for U.S. EPA to process the permits than when the states were doing it. 2. If a state that has the authority to regulate greenhouse gases does not implement the Tailoring Rule thresholds, U.S. EPA will likely disapprove the portion of the State Implementation Plan (SIP) that allows greenhouse gases to be regulated below the Tailoring Rule thresholds. In the meantime, regulatory gridlock and uncertainty will likely occur. Once U.S. EPA takes final action on the SIP, there will still be uncertainty as to the regulated emission thresholds for greenhouse gases under state law. 3. If a state adopts the Tailoring Rule thresholds into its own rules and submits a SIP revision to U.S. EPA requesting approval as part of its federally-approved plan, then the negative results described above in possible path #1 and possible path #2 will not occur. The state, and regulated industry, will still experience significant costs to implement the requirements. However, the costs to regulated industry and the amount of regulatory uncertainty are less under this path than the other paths. Therefore, Georgia EPD has proposed pursuing this path to incorporate the Tailoring Rule thresholds into our rulesand to submit a SIP revision to U.S. EPA requesting approval as part of our federallyapproved plan.

In conclusion, the costs imposed by regulating greenhouse gases under this proposed rule change are no more than that of the federal rule. And, the provisions of the Greenhouse Gas Tailoring Rule will provide cost savings and increased regulatory certainty to the regulated industry compared to the expected costs and lack of regulatory certainty that would result from not adopting the federal Greenhouse Gas Tailoring Rule. No direct costs will be imposed on local governments or the general public.

Due to the legal and political uncertainty regarding the Greenhouse Gas Tailoring Rule provisions, language has been included in the rule to make clear that regulation of greenhouse gases under the PSD permitting program in Georgia shall cease if it ceases at the federal level.Chapter 391-3-1 Rules for Air Quality Control

Rule 391-3-1-.03(10) Title V Operating Permits

The purpose of this revision is to reference the most recent versions of the various sections of 40 CFR Part 70 which includes revisions to Part 70.2 to incorporate the federal Greenhouse Gas Tailoring Rule.

The background and cost information on this rule is included above in the section on the Prevention of Significant Deterioration of Air Quality proposed rule change.

In conclusion, the costs imposed by regulating greenhouse gases under this proposed rule change are no more than that of the federal rule. And, the provisions of the Greenhouse Gas Tailoring Rule will provide cost savings and increased regulatory certainty to the regulated industry compared to the expected costs and lack of regulatory certainty that would result from not adopting the federal Greenhouse Gas Tailoring Rule. No direct costs will be imposed on local governments or the general public.

Due to the legal and political uncertainty regarding the Greenhouse Gas Tailoring Rule provisions, language has been included in the rule to make clear that regulation of greenhouse gases under the Title V permitting program in Georgia shall cease if it ceases at the federal

level.Chapter 391-3-1 Rules for Air Quality Control

DEPARTMENT OF NATURAL RESOURCES

ENVIRONMENTAL PROTECTION DIVISION RELATING TO AIR QUALITY, CHAPTER 391-3-1

The Rules of the Department of Natural Resources, Chapter 391-3-1, Air Quality Control are hereby amended, added to, repealed in part, revised, as hereinafter explicitly set forth in the attached amendments, additions, partial repeals, and revisions for specific rules, or such subdivisions thereof as may be indicated.

[Note: Underlined text is proposed to be added. Lined-through text is proposed for deletion.]

Rule 391-3-1-.02(7) “Prevention of Significant Deterioration of Air Quality,” is being

amended to read as follows:

(7) Prevention of Significant Deterioration of Air Quality.

(a) General Requirements.

1. The provisions of paragraph (7) shall apply to any source and the owner or operator of any source subject to any requirement under 40 C ode of Federal Regulations (hereinafter, CFR),

Part 52.21 as amended

. The subparagraphs of Paragraph (7) that incorporate by reference paragraphs of 40 CFR, Part 52.21 are as amended through June 3, 2010, unless otherwise specified.

2. Definitions: For the purpose of this paragraph, 40 CFR, Part 52.21 (b) as amended, is hereby incorporated by reference with the following exceptions:

(i) In lieu of the definition of “baseline actual emissions” as specified in paragraph (b)(48) of 40 CFR, Part 52.21, the following shall apply:

“Baseline actual emissions” means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with subparagraphs (7)(a)2.(i)(I) through (IV) of this rule.

(I) For any existing electric utility steam gener ating unit, baseline actual emissions means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive 24-month period selected by the owner or operator within the 5-year period immediately preceding when the owner or operator begins actual construction of the project. The Director shall allow the use of a different time period upon a determination that it is more representative of normal source operation.

I. The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions. However, fugitive emissions and/or emissions associated with startups, shutdowns, and malfunctions shall or may be excluded inChapter 391-3-1 Rules for Air Quality Control

accordance with the following subparagraphs A and B.

A. If fugitive emissions or emissions from startups, shutdowns, and/or malfunctions during the consecutive 24-month period selected by the owner or operator are not quantifiable and are therefore not included in the calculation of baseline actual emissions, then fugitive emissions or emissions from startups, shutdowns, and/or malfunctions, respectively, shall not be included in the calculation of projected actual emissions [as defined in subparagraph (7)(a)2.(ii) of this rule].

B. The owner or operator may elect to omit malfunctions from the calculation of baseline actual emissions. If the owner or operator elects to do so, then malfunctions shall also be omitted from the calculation of projected actual emissions [as defined in subparagraph (7)(a)2.(ii) of this rule].

II. The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive 24-month period.

III. For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period may be used to determine the baseline actual emissions for the emissions units being changed. A different cons ecutive 24-month period can be used for each regulated NSR pollutant.

IV. The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, or for which there is inadequate information for adjusting this amount downward to exclude any non-compliant emissions as required by subparagraph (7)(a)2.(i)(I)II. of this rule.

V. If any physical change(s) or change(s) in the method of operation subsequent to the consecutive 24-month period selected by the owner or operator resulted in a permanent change in the basic design parameter [as defined in subparagraph (7)(a)2.(viii) of this rule], not including the voluntary addition of air pollution control equipment or increase in removal or collection efficiency of existing air pollution control equipment, and thus resulted in a corresponding reduction in actual emissions of a regulated NSR pollutant, the baseline actual emissions shall be adjusted downward by a proportional reduction in emissions in tons per year or lbs/unit of production.

VI. The average rate shall be adjusted downwar d to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply, had such major source been required to comply with such limitations during the consecutive 24- month period. However, if an emission limitat ion is part of a Maximum Available Control Technology (MACT) standard that the Administrator of U.S. EPA has proposed or promulgated under 40 CFR, Part 63, the baseline actual emissions need only be adjusted if the Division has taken credit for such emission reductions in an attainment demonstration or maintentance plan consistent with the requirements of 40 CFR, Part 51.165(a)(3)(ii)(G).

(II) For an existing emissions unit (other than an electric utility steam generating unit), baseline actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive 24- month period selected by the owner or operator within the 10-year period immediately preceding either the date the owner or operator begins actual construction of the project, or the date a complete permit application is received by theChapter 391-3-1 Rules for Air Quality Control

Division for a permit required under this paragraph or by the reviewing authority for a permit required by a plan, whichever is earlier.

I. The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions. However, fugitive emissions and/or emissions associated with startups, shutdowns, and malfunctions shall or may be excluded in accordance with the following subparagraphs A and B.

A. If fugitive emissions or emissions from startups, shutdowns, and/or malfunctions during the consecutive 24-month period selected by the owner or operator are not quantifiable and are therefore not included in the calculation of baseline actual emissions, then fugitive emissions or emissions from startups, shutdowns, and/or malfunctions, respectively, shall not be included in the calculation of projected actual emissions (as defined in subparagraph (7)(a)2.(ii) of this rule).

B. The owner or operator may elect to omit malfunctions from the calculation of baseline actual emissions. If the owner or operator elects to do so, then malfunctions shall also be omitted from the calculation of projected actual emissions [as defined in subparagraph (7)(a)2.(ii) of this rule].

II. The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive 24-month period.

III. The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply, had such major stationary source been required to comply with such limitations during the consecutive 24-month period. However, if an emission limitation is part of a Maximum Achievable Control Technology (MACT) standard that the Administrator of U.S. EPA has proposed or promulgated under 40 CFR, Part 63, the baseline actual emissions need only be adjusted if the Division has taken credit for such emissions reductions in an attainment demonstration or maintenance plan consistent with the requirements of 40 CFR, Part 51.165(a)(3)(ii)(G).

IV. For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period may be used to determine the baseline actual emissions for all the emissions units being changed. A different cons ecutive 24-month period can be used for each regulated NSR pollutant.

V. The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, or for which there is inadequate information for adjusting this amount downward to exclude any non-compliant emissions as required by subparagraph (7)(a)2.(i)(II)II or III. of this rule.

VI. If any physical change(s) or change(s) in the method of operation subsequent to the consecutive 24-month period selected by the owner or operator resulted in a permanent change in the basic design parameter [as defined in subparagraph (7)(a)2.(viii) of this Rule], not including the voluntary addition of air pollution control equipment or increase in removal or collection efficiency of existing air pollution control equipment, and thus resulted in a corresponding reduction in actual emissions of a regulated NSR pollutant, the baseline actualChapter 391-3-1 Rules for Air Quality Control

emissions shall be adjusted downward by a proportional reduction in emissions in tons per year or lbs/unit of production.

(III) For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential to emit [as long as the unit remains a “new emissions unit” as defined in 40 CFR, Part 52.21(b)(7)(i)].

(IV) For a PAL for a stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in subparagraph (7)(a)2.(i)(I) of this rule, for other existing emissions units in accordance with the procedures contained in subparagraph (7)(a)2.(i)(II) of this rule, and for a new emissions unit in accordance with the procedures contained in subparagraph (7)(a)2.(i)(III) of this rule. For existing emission units, the baseline actual em issions shall be based on any consecutive 24- month period selected by the operator within the appropriate PAL baseline period. For existing electric steam generating units, the PAL baseline period is the 5-year period (or different period allowed by the Director that is more representative or normal source operation) immediately preceding submission of a complete PAL application to the Division. For other existing emission units, the PAL baseline period is the 10-year period immediately preceding submission of a complete PAL permit application to the Division.

(ii) In lieu of the definition of “projected actual emissions” as specified in paragraph (b)(41) of 40 CFR, Part 52.21, the following shall apply:

(I) “Projected actual emissions” means the maximum annual rate, in tons per year, at which an existing emissions unit is projected to emit a regulated NSR pollutant in any one of the 5 years (12-month period) following the date the unit resumes regular operation after the project, or in any one of the 10 years following that date, if the project involves increasing the emissions unit's design capacity or its potential to emit that regulated NSR pollutant and full utilization of the unit would result in a significant emissions increase or a significant net emissions increase at the major stationary source.

(II) In determining the projected actual emissions under subparagraph (7)(a)2.(ii)(I) (before beginning actual construction), the owner or operator of the major stationary source:

I. Shall consider all relevant information, including but not limited to, historical operational data, the company's own representations, the co mpany's expected busi ness activity and the company's highest projections of business activity, the company's filings with the State or Federal regulatory authorities, and compliance plans under the approved State Implementation

Plan; and

II. Shall include fugitive emissions to the extent quantifiable and emissions associated with startups, shutdowns, and malfunctions. However, fugitive emissions and/or emissions associated with startups, shutdowns, and malfunctions shall or may be excluded in accordance with the following subparagraphs A, B, and C.

A. If projected fugitive emissions or emissions from startups, shutdowns, and/or malfunctions are not quantifiable and are therefore not included in the calculation of projected actual emissions, then fugitive emissions or emissions from startups, shutdowns, and/or malfunctions,Chapter 391-3-1 Rules for Air Quality Control

respectively, shall not be included in the calculation of baseline actual emissions [as defined in subparagraph (7)(a)2.(i) of this rule].

B. The owner or operator may elect to omit malfunc tions from the calculation of projected actual emissions. If the owner or operator elects to do so, then malfunctions shall also be omitted from the calculation of baseline actual emissions [as defined in subparagraph (7)(a)2.(i) of this rule].

C. If the project involves increasing the emissi ons unit's design capacity or its potential to emit that regulated NSR pollutant and the increase in projected emissions associated with startups, shutdowns, and malfunctions is not proportional to the increase in the emission unit’s design capacity or its potential to emit that regulated NSR pollutant, the owner or operator must include with the information required under subparagraph (7)(b)15.(i)(I) of this rule documentation that supports the projected emissions associated with startups, shutdowns, and malfunctions subsequent to completion of the project; and

III. May exclude, in calculating any increase in emissions that results from the particular project, that portion of the unit's emissions following the project that an existing unit could have accommodated during the consecutive 24-month period used to establish the baseline actual emissions under subparagraph (7)(a)2.(i) of this rule and that is also unrelated to the particular project, including any increased utilization due to product demand growth (the increase in emissions that may be excluded under this subparagraph shall hereinafter be referred to as “demand growth emissions”);

A. If the project involves increasing the emissi ons unit's design capacity or its potential to emit that regulated NSR pollutant, the owner or operator shall either:

(A) not exclude demand growth emissions, or

(B) must include in the information required under subparagraph (7)(b)15.(i)(I) of this paragraph, documentation that demand growth emissi ons are emissions that the emissions unit could have accommodated during the consecutive 24-month period used to establish the baseline actual emissions, are not related to the particular project, and are due to product demand growth; must have documentation supporting the portion of the emissions increase that is due to demand growth; and, following the change, must be able to track the emissions increase due to demand growth; or

IV. In lieu of using the method set out in subparagraphs (7)(a)2.(ii)(II)I. through III. of this rule, may elect to use the emissions unit's potential to emit, in tons per year, as defined under paragraph (b)(4) of 40 CFR, Part 52.21.

(iii) The definition of “major stationary source” contained in 40 CFR, Part 52.21(b)(1) is hereby incorporated by reference except as follows:

(I) Subparagraph (i)(b) shall read as follows: Notwithstanding the stationary source size specified in paragraph (b)1.(i)(a) of this section, any stationary source which emits, or has the potential to emit, 250 tons-per-year or more of a regulated NSR pollutant; or

(iv) The definition of “major modification” contained in 40 CFR, Part 52.21(b)(2), shall be

modified as follows:Chapter 391-3-1 Rules for Air Quality Control

(I) paragraph (iii)(h), relating to the addition, replacement, or use of a PCP, is not adopted.

(iv) The definition and use of the term “subject to regulation” in 40 CFR, Part 52.21, as amended June 3, 2010, is hereby incorporated by re ference; provided, however, that in the event all or any portion of 40 CFR, Part 52.21 containing that term is:

(I) declared or adjudged to be invalid or unconstitutional or stayed by the United States Court of Appeals for the Eleventh Circuit or for the District of Columbia Circuit; or

(II) withdrawn, repealed, revoked or otherwise rendered of no force and effect by the United States Environmental Protection Agency, C ongress, or Presidential Executive Order.

Such action shall render the regulation as incorporated herein, or that portion thereof that may be affected by such action, as invalid, void, stayed, or otherwise without force and effect for purposes of this rule upon the date such action becomes final and effective; provided, further, that such declaration, adjudication, stay, or other action described herein shall not affect the remaining portions, if any, of the regulation as incorporated herein, which shall remain of full force and effect as if such portion so declared or adjudged invalid or unconstitutional or stayed or otherwise invalidated or effected were not originally a part of this rule. The Board declares that it would have incorporated the remaining parts of the federal regulation if it had known that such portion thereof would be declared or adjudged invalid or unconstitutional or stayed or

otherwise rendered of no force and effect;

(v) The definition of “potential to emit” contained in 40 CFR, Part 52.21(b)(4), shall be modified

as follows:

(I) The phrase “is federally enforceable” shall read “is federally enforceable or enforceable as a practical matter.”

(vi) The definition of “allowable emissions” contained in 40 CFR, Part 52.21(b)(16), shall be

modified as follows:

(I) The phrase “unless the source is subject to federally enforceable limits which restrict the operating rate, or hours of operation, or both” shall read, “unless the source is subject to enforceable limits which restrict the operating rate, or hours of operation, or both.”

(II) paragraph (iii) shall read as follows: The emissions rate specified as an enforceable permit condition, including those with a future compliance date.

(vii) The following shall be added to the definition of “major source baseline date” contained in 40 CFR, Part 52.21(b)(14):

(I) Baseline dates established prior to April 19, 2006, will remain in effect.

(viii) In lieu of paragraph (b)(33)(iii) of the definition of “replacement unit” as specified in paragraph (b)(33) of 40 CFR, Part 52.21, the following shall apply:Chapter 391-3-1 Rules for Air Quality Control

The replacement does not alter the basic design parameters of the process unit. Basic design parameters are defined as follows:

(I) Except as provided in subparagraph (7)(a)2.(viii)(III) of this rule, for a process unit at a steam electric generating facility, the owner or operat or may select as its basic design parameters either maximum hourly heat input and maximum hourly fuel consumption rate or maximum hourly electric output rate and maximum steam flow rate. When establishing fuel consumption specifications in terms of weight or volume, the minimum fuel quality based on British Thermal Units content shall be used for determining the basic design parameter(s) for a coal-fired electric utility steam generating unit.

(II) Except as provided in subparagraph (7)(a)2.(viii)(III) of this rule, the basic design parameter(s) for any process unit that is not at a steam electric generating facility are maximum rate of fuel or heat input, maximum rate of material input, or maximum rate of product output. Combustion process units will typically use maxi mum rate of fuel input. For sources having multiple end products and raw materials, the owner or operator should consider the primary product or primary raw material when selecting a basic design parameter.

(III) If the owner or operator believes the basic design parameter(s) in subparagraphs (7)(a)2.(viii)(I) and (II) of this rule is (are) not appropriate for a specific industry or type of process unit, the owner or operator may propose to the Division an alternative basic design parameter(s) for the source's process unit(s). If the Director approves of the use of an alternative basic design parameter(s), he or she shall issue a permit that is legally enforceable that records such basic design parameter(s) and requires the owner or operator to comply with such parameter(s).

(IV) The owner or operator shall use credible information, such as results of historic maximum capability tests, design information from the manufacturer, or engineering calculations, in establishing the magnitude of the basic design parameter(s) specified in subparagraphs (7)(a)2.(viii)(I) and (II) of this rule.

(V) If design information is not available for a process unit, then the owner or operator shall determine the process unit's basic design param eter(s) using the maximum value achieved by the process unit in the five-year period immediately preceding the planned activity.

(VI) Efficiency of a process unit is not a basic design parameter.

(ix) [reserved] The definition of “pollution control project,” as specified in paragraph (b)(32) of 40 CFR, Part 52.21, is not adopted.

(x) [reserved] The definition of “clean unit,” as specified in paragraph (b)(42) of 40 CFR Part 52.21, is not adopted.

(xi) In the definition of “net emissions increase” as specified in paragraph (b)(3) of 40 CFR Part 52.21, paragraphs (iii)(b) and (vi)(d), related to increases and decreases at a clean unit, are not adopted.

(IV) The ability of EPA to obtain information from a source pursuant to section 114 of the federal Clean Air Act or of the Director to obtain information from a source pursuant to section 391-3-1-.02(6).

7. Emergency Provision: For the purpose of paragraph (d)7., 40 CFR Part 70.6(g) as amended promulgated July 21, 1992, is hereby incorporated and adopted by reference.

(e) Permit Issuance, Renewal, Reopenings and Revisions.

1. Action on application.

(i) A permit, permit modification, or renewal may be issued only if all of the following conditions

have been met:

(I) The Director has received a complete application, except that a complete application need not be received before issuance of a general permit under subsection (d);

(II) Except for modifications qualifying for minor permit modification procedures under subparagraphs (e)5.(i) or (e)5.(ii), the Director has complied with the requirements for public participation under paragraph (e)8.;

(III) The Director has complied with the requirements for notifying and responding to affected States under subsection (f);

(IV) The conditions of the permit provide for compliance with all applicable requirements; and

(V) The EPA Administrator has received a copy of the proposed permit and any notices required under subsection (f) and has not objected to issuance of the permit under subsection (f) within the time period specified therein.Chapter 391-3-1 Rules for Air Quality Control

(ii) Except as provided under the initial tr ansition plan or under regulations promulgated under Title IV of the federal Clean Air Act, the Director shall take final action on each permit application (including request for permit modification or renewal) within 18 months after receiving a complete application.

(iii) The Director shall provide a statement that sets forth the legal and factual basis for the draft permit conditions (including references to the applicable statutory or regulatory provisions). The

Director shall send this statement to EPA and to any other person who requests it.

(iv) The submittal of a complete application shall not affect the requirement that any source have a preconstruction permit under Section 391-3-1-.03(8).

2. Requirement for a permit.

Except as provided in paragraph (b)5., Part (e)5.(i)(V) and Part (e)5.(ii)(V), no Part 70 source may operate after the time that it is required to submit a timely and complete application, except in compliance with a permit issued under this section (10). If a Part 70 source submits a timely and complete application for permit issuance (including for renewal), the source’s failure to have a Part 70 permit is not a violation until the Director takes final action on the permit application. This protection shall cease to apply if, subsequent to the completeness determination, the applicant fails to submit by the deadline specified in writing by the Director any additional information identified as being needed to process the application.

3. Permit renewal and expiration.

(i) Permits being renewed are subject to the same procedural requirements, including those for public participation, affected State and EPA review , that apply to initial permit issuance.

(ii) Permit expiration terminates the source’s right to operate unless a timely and complete renewal application has been submitted.

(iii) If a timely and complete application for permit renewal is submitted, but the Director has failed to issue or deny the renewal permit before the end of the term of the previous permit, then the permit shall not expire until the renewal permit has been issued or denied and any permit shield that may be granted pursuant to paragraph (d)6. shall extend beyond the original permit

term until renewal.

4. Administrative permit amendments.

(i) Definitions: For the purpose of this paragraph, 40 CFR, Part 70.7(d)(1), as

amended promulgated July 21, 1992 , is incorporated and adopted by reference.

(ii) Administrative permit amendments for purposes of the acid rain portion of the permit shall be governed by regulations promulgated under Title IV of the federal Clean Air Act.

(iii) An administrative permit amendment may be made by the Director consistent with the following:Chapter 391-3-1 Rules for Air Quality Control

(I) The Director shall take no more than 60 days from receipt of a request for an administrative permit amendment to take final action on such request, and may incorporate such changes without providing notice to the public or affected States provided that it designates any such permit revisions as having been made pursuant to this paragraph.

(II) The Director shall submit a copy of the revised permit to the EPA Administrator.

(III) The source may implement the changes addressed in the request for an administrative amendment immediately upon submittal of the request.

(iv) The Director may, upon taking final action granting a request for an administrative permit amendment, allow coverage by the permit shie ld for administrative permit amendments made pursuant to 40 CFR Part 70.7(d)(1)(v), which is incorporated by reference in Subparagraph (e)4.(i) of this rule, which meet the requirements for significant permit modifications.

5. Permit modification.

A permit modification is any revision to a Part 70 permit that cannot be accomplished under paragraph 4. A permit modification for purposes of the acid rain program shall be governed by regulations promulgated under Title IV of the federal Clean Air Act.

(i) Minor permit modification procedures.

(I) Minor permit modification procedures may be used only for those permit modifications that:

I. Do not violate any applicable requirement;

II. Do not involve significant changes to existing monitoring, reporting, or recordkeeping requirements in the permit;

III. Do not require or change a case-by-case determination of an emission limitation or other standard, or a source specific determination for temporary sources of ambient impacts, or a visibility or increment analysis;

IV. Do not seek to establish or change a permit term or condition for which there is no corresponding underlying applicable requirement and t hat the source has assumed to avoid an applicable requirement to which the source would otherwise be subject, including a federally enforceable emissions cap assumed to avoid classification as a modification under any provision of 391-3-1-.03(8), and an alternative em issions limit approved pursuant to regulations promulgated under section 112(j)(5) of the federal Clean Air Act;

V. Are not modifications under any provision of 391-3-1-.03(8); and

VI. Are not required by this section (10) to be processed as a significant modification.

(II) An application requesting the use of minor permit modification procedures shall meet the requirements of subsection 8 and shall include the following:Chapter 391-3-1 Rules for Air Quality Control

I. A description of the change, the emissions resulting from the change, and any new applicable requirements that will apply if the change occurs;

II. The source’s suggested draft permit;

III. Certification by a responsible official, consistent with subsection (c), that the proposed modification meets the criteria for use of minor modification procedures and a request that such procedures be used; and

IV. Completed forms for the Director to use to notify the EPA Administrator and affected States as required under subsection (f).

The Director shall promptly send any notice required under subparagraph (f)(2)(ii) to the EPA Administrator.

(IV) The Director may not issue a final permit modification until after EPA’s 45-day review period or until EPA has notified the Director that EPA will not object to issuance of the permit modification, whichever is first, although the Director can approve the permit modification prior to that time. Within 90 days of the Director’s receipt of an application under minor permit modification procedures or 15 days after the end of the EPA Administrator’s 45-day review period under paragraph (f)(3), whichever is later, the Director shall:

I. Issue the permit modification as proposed;

II. Deny the permit modification application;

III. Determine that the requested modification does not meet the minor permit modification criteria and should be reviewed under the significant modification procedures; or

IV. Revise the draft permit modification and transmit to the EPA Administrator the new proposed permit modification as required by subsection (f).

(V) The source may make changes proposed in its minor permit modification application as

follows:

I. For proposed changes that require a permit in accordance with 391-3-1-.03(1), the source may make the change proposed in its minor permit modification application immediately after obtaining a permit for the modification pursuant to the requirements of 391-3-1-.03(1). After the source makes such change and until the Director takes any of the actions specified in Part (IV), the source must comply with the applicable requirements governing the change, the proposed permit terms and conditions, and requirements of the construction permit issued under 391-3-1- .03(1). During this time period, the source need not comply with the existing permit terms and conditions it seeks to modify. However, if the source fails to comply with its proposed permit terms and conditions and the requirements of the construction permit issued under 391-3-1- .03(1) during this time period, the existing permi t terms and conditions it seeks to modify and the requirements of the construction permit issued under 391-3-1-.03(1) may be enforced against it.Chapter 391-3-1 Rules for Air Quality Control

II. For proposed changes that do not require a permit in accordance with 391-3-1-.03(1), the source may make the change proposed in its minor permit modification application upon receipt of a letter from the Division acknowledging receipt of said application. If the Director denies the permit modification application in accordance with Part (IV)II, the existing terms and conditions that the applicant seeks to modify may be enforced by the Division.

(VI) The permit shield may not extend to minor permit modifications.

(ii) Group processing of minor permit modifications. The Director may modify the procedure outlined in subparagraph (e)5.(i) to process groups of a source’s applications for certain modifications eligible for minor permit modification processing.

(I) Group processing of modifications may be used only for those permit modifications:

I. That meet the criteria for minor permit modification procedures under subparagraph (e)5.(i);

and

II. That collectively are below 10 percent of the emissions allowed by the permit for the emissions unit for which the change is requested, 20 percent of the applicable definition of major source in paragraph (a)4., or 5 tons per year, whichever is least.

(II) An application requesting the use of group processing procedures shall meet the requirements of paragraph (c)2. and shall include the following:

I. A description of the change, the emissions resulting from the change, and any new applicable requirements that will apply if the change occurs.

II. The source’s suggested draft permit.

III. Certification by a responsible official that the proposed modification meets the criteria for use of group processing procedures under a request that such procedures be used.

IV. A list of the source’s other pending applications awaiting group processing, and determination of whether the requested modification, aggregated with these other applications, equals or exceeds the threshold set under Subpart (e)5.(ii)(I)II.

V. Certification that the source has notified EPA of the proposed modifica tion. Such notification need only contain a brief description of the proposed modification.

VI. Completed forms for the Director to use to notify the EPA Administrator and affected States as required under subsection (f).

(III) On a quarterly basis or within five business days of receipt of an application demonstrating that the aggregate of a source’s pending applicat ions equals or exceeds the threshold level set in Subpart (e)5.(ii)(I)II., whichever is earlier, the Director promptly shall comply with paragraphs (f)(1) and (f)(2). The Director shall send any notice required under subparagraph (f)(2)(ii) to the

EPA Administrator.Chapter 391-3-1 Rules for Air Quality Control

(IV) The provisions of Part (e)5.(i)(IV) shall apply to modifications eligible for group processing, except that the Director shall take one of the actions specified in Subparts (e)5.(i)(IV)I through IV. within 180 days of receipt of the application or 15 days after the end of the EPA Administrator’s 45-day review period under paragraph (f)(3), whichever is later.

(V) The provisions of Part 5.(i)(V) shall apply to modifications eligible for group processing.

(VI) The provisions of Part 5.(i)(VI) shall also apply to modifications eligible for group processing.

(iii) Significant modification procedures.

(I) Significant modification procedures shall be used for applications requesting permit modifications that do not qualify as minor permit modifications or as administrative amendments. At a minimum, every significant change in existing monitoring permit terms or conditions and every relaxation of reporting or recordkeeping permit terms or conditions shall be considered significant. Nothing herein shall be construed to preclude the permittee from making changes consistent with this section (10) that would render existing permit compliance terms

and conditions irrelevant.

(II) Significant permit modifications shall meet all requirements of this section (10), including those for applications, public participation, review by affected States, and review by EPA, as they apply to permit issuance and permit renewal.

6. Reopening for cause.

(i) A permit shall be reopened and revised under any of the following circumstances:

(I) Additional applicable requirements become applicable to a major Part 70 source with a remaining permit term of three or more years. Such a reopening shall be completed not later than 18 months after promulgation of the applicable requirement. No such reopening is required if the effective date of the requirement is later than the date on which the permit is due to expire, unless the original permit or any of its terms and conditions has been extended under subparagraph (e)3.(iii).

(II) Additional requirements (including excess emissions requirements) become applicable to an affected source under the acid rain program. Upon approval by the Administrator, excess emissions offset plans shall be deemed to be incorporated into the permit.

(III) The Director determines that the permit contains a material mistake or that inaccurate statements were made in establishing the emissi ons standards or other terms or conditions of the permit.

(IV) The Director determines that the permit must be revised or revoked to assure compliance with the applicable requirements.

(ii) Proceedings to reopen and issue a permit shall follow the same procedures as apply to initial permit issuance and shall affect only those parts of the permit for which cause to reopen

exists.Chapter 391-3-1 Rules for Air Quality Control

(i) Reopenings shall not be initiated before a notice of such intent is provided to the source by the Director at least 30 days in advance of the date that the permit is to be reopened, except that the Director may provide a shorter time period in the case of an emergency.

7. Reopenings for cause by EPA.

(i) If the EPA Administrator finds that cause exists to terminate, modify or revoke and reissue a permit pursuant to Paragraph 6. and notifies the Director of such finding in writing, the Director shall, within 90 days after receipt of such notification, forward to EPA a proposed determination

of termination, modification, or revoca tion and reissuance, as appropriate. If the EPA Administrator finds that a new or revised permit application is necessary or that the Director must require the permittee to submit additional information and extends this 90 day period, the Director shall forward the subject determination within 180 days of receipt of EPA’s notification.
