Environmental Protection Agency (EPA).
EPA is proposing to approve revisions to the Georgia State Implementation Plan (SIP), submitted by the Georgia Environmental Protection Division (GA EPD) in three submittals dated October 31, 2006, March 5, 2007, and August 22, 2007. The submittals include modifications to Georgia's Rules for Air Quality Control, Chapter 391-3-1. The October 31, 2006, revision includes changes to “Permit Exemption for Combustion Equipment.” The March 5, 2007, revisions include changes to “NOX (Nitrogen Oxides) Emissions from Electric Utility Steam Generating Units,” and “Emission Statements.” Finally, the August 22, 2007, submittal contains revisions to “Volatile Organic Compound,” “Provisions,” and “Stationary Engines.” EPA is not acting on the August 22, 2007, revisions to rule 391-3-1-.03(6) “Exemptions, Combustion Equipment” in this action. EPA is also not acting on the August 22, 2007, revisions to rule 391-3-1-.03(9), as it is not part of the federally-approved SIP. These submittals included revisions to Georgia's Prevention of Signification Deterioration and Nonattainment New Source Review programs, which EPA addressed in a separate action (73 FR 51606). This action is being taken pursuant to section 110 of the Clean Air Act (CAA).

I. EPA's Action
On October 31, 2006, March 5, 2007, and August 22, 2007, GA EPD submitted proposed SIP revisions to EPA for review and approval into the Georgia SIP. The rules became state effective on April 19, 2006, March 12, 2007, and July 25, 2007, respectively. The revisions include changes made by the State of Georgia to Chapter 391-3-1. Specifically, the October 31, 2006, revision includes changes to Rule 391-3-1-.03(6)(b) “Permit Exemption for Combustion Equipment.” The March 5, 2007, revisions include changes to Rules 391-3-1-.02(2)(jjj) “NOX Emissions from Electric Utility Steam Generating Units,” and 391-3-1-.02(6)(a)4 “Emission Statements.” Finally, the August 22, 2007, submittal contains revisions to Rules 391-3-1-.01(llll) Start Printed Page 23813“Volatile Organic Compound,” 391-3-1-.02 “Provisions,” and 391-3-1-.03(6)(b)11 “Stationary Engines.” EPA is now proposing to approve these revisions. The revisions summarized below are approvable pursuant to section 110 of the CAA.
EPA is not acting on the August 22, 2007, revisions to rule 391-3-1-.03(6) “Exemptions, Combustion Equipment” in this action. Additionally, EPA is not acting on the August 22, 2007, revisions to rule 391-3-1-.03(9), as it is not part of the federally-approved SIP.
II. Analysis of Georgia's Submittals
October 31, 2006, Submittal
Rule 391-3-1-.03(6)(b), “Permit Exemption for Combustion Equipment”
This revision adds two new subparagraphs, (b)14 and 15, for the purpose of exempting temporary boilers and electric generators that are used to replace a facility's boilers or generators during periods of repair or maintenance, from the requirement to obtain a permit. Fuel-burning equipment that remains at a location for more than 180 consecutive days is no longer considered to be a temporary boiler. Temporary fuel-burning equipment that replaces temporary equipment at a location to perform the same function will be included in calculating the total consecutive time period. This revision provides language stating the exemption is permissible “provided the actual and potential emissions of the temporary sources do not exceed that of the main source.” This rule revision is meant to streamline the permitting process for certain operators, and no longer requires stationary sources that install temporary boilers and electric generators to obtain a permit for the temporary equipment operated during periods of maintenance or repair.
March 5, 2007, Submittal
Rule 391-3-1-.02(2)(jjj), “NOX Emissions from Electric Utility Steam Generating Units”
The revision amends NOX emission limits in subparagraphs (jjj)4.,5.,6.,7., and 8., for coal-fired electric utility steam generating units with a maximum heat input greater than 250 Million British thermal units per hour (MMBtu/hr). The limit is based on a 30-day rolling average (averaged over all existing units) and was effective at the beginning of the 2007 ozone season, which runs from May 1st through September 30th in Georgia. Consistent with the existing regulation, unit-specific NOX limits are to be established in a permit. This limit is also included as part of the Macon, Georgia, 8-hour ozone maintenance plan (72 FR 53432).
Subparagraph 4 specifies that the previous NOX emissions limit of 0.20 lb/MMBtu was effective through September 30, 2006. Subparagraph 5, which was effective May 1, 2007, lowers the existing 7-plant emission limit to 0.18 lb/MMBtu, to account for lower NOX emissions from Plant Scherer. The requirements of subparagraphs 4 and 5 apply to all sources located in Bartow, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Floyd, Forsyth, Fulton, Gwinnett, Heard, Henry, Monroe, Paulding, Putnam, and Rockdale Counties.
Subparagraph 6 establishes an ozone season NOX emission limit of 0.17 lb/MMBtu for Georgia Power's Plant Scherer, located in Monroe County. The requirements in subparagraph 6 apply to sources located in Monroe County. These revisions also establish an ozone season NOX emissions limit for Georgia Power's Plant Scherer, which is located in the Macon area, and also contributes to ozone levels in the Atlanta nonattainment area.
Rule 391-3-1-.02(6)(a)4, “Emission Statements”
The revision amends subparagraph (a)4 to revise the emission statement requirements to be consistent with the Federal regulations for 8-hour ozone nonattainment areas. The Emission Statement deadline is changed from July 31st to June 15th of each calendar year. Additionally, applicability of the requirements is expanded to include the counties of Barrow, Bartow, Carroll, Hall, Newton, Spalding and Walton, which are parts of the Atlanta 8-hour ozone nonattainment area. The basis of this rule is to require submission of NOX and volatile organic compounds (VOC) emissions inventories for sources located in the Atlanta ozone non-attainment area. The purpose of the revision is to make the rule consistent with current federal regulations for 8-hour ozone nonattainment areas.
August 22, 2007, Submittal
Rule 391-3-1-.01(llll), “Volatile Organic Compound”
The revision submitted by GA EPD adds one compound to the list of those excluded from the definition of VOC, on the basis that the compound makes a negligible contribution to ozone formation. Tropospheric ozone, commonly known as smog, occurs when VOCs and NOX react in the atmosphere. Because of the harmful health effects of ozone, EPA limits the amount of VOCs and NOX that can be released into the atmosphere. VOCs are those compounds of carbon (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides, or carbonates, and ammonium carbonate) which form ozone through atmospheric photochemical reactions. Compounds of carbon (or organic compounds) have different levels of reactivity; they do not react at the same speed, or do not form ozone to the same extent.
It has been EPA's policy that compounds of carbon with a negligible level of reactivity need not be regulated to reduce ozone (42 FR 35314, July 8, 1977). EPA determines whether a given carbon compound has “negligible” reactivity by comparing the compound's reactivity to the reactivity of ethane. EPA lists these compounds in its regulations at 40 CFR 51.100(s), and excludes them from the definition of VOC. The chemicals on this list are often called “negligibly reactive.” EPA may periodically revise the list of negligibly reactive compounds to add compounds to or delete them from the list. GA EPD's revision modified the definition of VOC to exclude: 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-trifluoromethylpentane.
This revision updates the definition of VOC, to comply with the Federal list of compounds designated as having negligible photochemical reactivity.
Rule 391-3-1-.02, “Provisions”
GA EPD is revising paragraph (12) “Clean Air Interstate Rule NOX Annual Trading Program,” by deleting inadvertent references and inserting the correct references in subparagraphs (f)3(iii), (g)1(i) and (g)1(ii). The rule is being revised to correct cross-references. Subparagraph (f)3(iii) inadvertently references the wrong subparagraphs for determining the control period for baseline heat input for NOX allocations. Revisions to subparagraph (f)3(iii) updates the reference to subparagraph (f)2(i) and (ii), and (f)2.(iii) with references to subparagraphs (f)3.(i) and (ii), and (f)3.(i) through (f)3.(ii), respectively. Subparagraphs (g)1.(i) and (ii) are amended to be consistent with the changes to subparagraph (f)3.(iii) above, as well as to add a wording change to clarify the control period. Specifically, the reference in subparagraph (g)1.(i) currently stated as “(f)2. through (f)3.,” is updated to correctly read “(f)1.(i).” The current reference in (g)1.(ii) to subparagraph (f)2. through (f)3 is also revised to “(f)1.(ii).” Additionally, the words “that is four years” are added to describe the control period in subparagraph (g)1.(ii).Start Printed Page 23814
Rule 391-3-1-.03(6)(b)11, “Stationary Engines”
The revision corrects an inadvertent error in subparagraphs (iii) and (iv) to read “hours-per-year,” rather than “hours-per-hour.”
III. Proposed Action
EPA is proposing to approve the aforementioned revisions, specifically, Chapters 391-3-1-.03(6)(b), 391-3-1-.02(2)(jjj), 391-3-1-.02(6)(a)4, 391-3-1-.01(llll), 391-3-1-.02, and 391-3-1-.03(6)(b)11, into the Georgia SIP. These revisions were submitted by GA EPD on October 31, 2006, March 5, 2007, and August 22, 2007.
IV. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this proposed action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:
- Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
- Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
- Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
- Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
- Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
- Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
- Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
- Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
- Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.Start List of Subjects
