 Environmental Protection Agency 40 CFR Part 81
[EPA-R04-OAR-2010-0614-201036; FRL-9203-1]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Proposed rule.
 SUMMARY: The State of Georgia, through the Georgia Department of Natural Resources (GA DNR), submitted a letter on June 9, 2010, with a request for EPA to grant a one-year extension of the attainment date for the 1997 8-hour ozone national ambient air quality standards (NAAQS) for the Atlanta, Georgia Area (hereafter referred to as the “Atlanta Area”). The Atlanta Area consists of Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding, and Walton Counties. In today's action, EPA is proposing to determine that the State of Georgia has met the Clean Air Act (CAA or the Act) requirements to obtain a one-year extension to its attainment date for the 1997 8-hour ozone NAAQS for the Atlanta Area. As a result, EPA is proposing to approve a one-year extension of the 1997 8-hour ozone moderate attainment date for the Atlanta Area. Specifically, EPA is proposing to extend the Atlanta Area's attainment date from June 15, 2010, to June 15, 2011.
 DATES: Comments must be received on or before October 18, 2010.

SUPPLEMENTARY INFORMATION: I. Background II. Today's Action III. EPA's Analysis of the State's Requests for an Attainment Date Extension for the Atlanta Area for the 1997 8-Hour Ozone NAAQS IV. Proposed Actions V. Statutory and Executive Order Reviews I. Background A. 1997 8-Hour Ozone NAAQS On July 18, 1997, EPA promulgated a revised 8-hour ozone NAAQS of 0.08 parts per million (ppm). Under EPA's regulations at 40 CFR part 50, the 1997 8-hour ozone NAAQS is attained when the 3-year average of the annual fourth highest daily maximum 8-hour average ambient air quality ozone concentrations is less than or equal to 0.08 ppm (
                    *i.e.,*
                     0.084 ppm when rounding is considered) (69 FR 23857, April 30, 2004).[1]
                    
                     Ambient air quality monitoring data for the 3-year period must meet a data completeness requirement. The ambient air quality monitoring data completeness requirement is met when the average percent of days with valid ambient monitoring data is greater than 90 percent, and no single year has less than 75 percent data completeness as determined in Appendix I of part 50. Upon promulgation of a new or revised NAAQS, the CAA requires EPA to designate as nonattainment any area that is violating the NAAQS, based on the three most recent years of ambient air quality data at the conclusion of the designation process. The Atlanta Are a was designated nonattainment for the 1997 8-hour ozone NAAQS on April 30, 2004 (effective June 15, 2004) using 2001-2003 ambient air quality data (69 FR 23857, April 30, 2004). At the time of designation the Atlanta Area was classified as a marginal nonattainment area for the 1997 8-hour ozone NAAQS. In the April 30, 2004, Phase I Ozone Implementation Rule, EPA established ozone nonattainment area attainment dates based on Table 1 of Section 181(a) of the CAA. This established an attainment date 3 years after the June 15, 2004, effective date for areas classified as marginal areas for the 1997 8-hour ozone nonattainment designations. Therefore, the Atlanta Area's original attainment date was June 15, 2007. (
                    *See*69 FR 23951, April 30, 2004.) The Atlanta Area failed to attain the 1997 8-hour ozone NAAQS by June 15, 2007 (the applicable attainment date for marginal nonattainment areas), and did not qualify for any extension of the attainment date as a marginal area. As a consequence of this failure, on March 6, 2008, EPA published a rulemaking determining that the Atlanta Area failed to attain and, consistent with Section 181(b)(2) of the CAA, the Atlanta Area was reclassified by operation of law to the next highest classification, or “moderate” nonattainment. (
                    *See*72 FR 58572, October 16, 2007.) When an area is reclassified, a new attainment date for the reclassified area must be established. Section 181 of the CAA explains that the attainment date for moderate nonattainment areas shall be as expeditiously as practicable, but no later than six years after designation, or June 15, 2010. EPA further required that Georgia submit the SIP revisions meeting the new moderate area requirements as expeditiously as practicable, but no later than December 31, 2008. Georgia submitted SIP revisions to address the moderate area requirements for the Atlanta Area on October 21, 2009. EPA is in the process of reviewing these submissions and will take action on these submissions in rulemaking separate from today's proposed action. Under certain circumstances, the CAA allows for extensions of the attainment dates prescribed at the time of the original nonattainment designation. 
                    *See*
                     below for further discussion. B. CAA Requirements for One-Year Extension Requests Section 181(b)(2)(A) requires the Administrator, within six months of the attainment date, to determine whether an ozone nonattainment area attained the NAAQS. CAA Section 181(b)(2)(A) states that, for areas classified as marginal, moderate, or serious, if the Administrator determines that the area did not attain the standard by its attainment date, the area must be reclassified to the next classification. However, in accordance with CAA Section 181(a)(5), EPA may grant up to 2 one-year extensions of the attainment date under specified conditions. Specifically, Section 181(a)(5) states: “Upon application by any State, the Administrator may extend for 1 additional year (hereinafter referred to as the ”Extension Year”) the date specified in table 1 of paragraph (1) of this subsection if— (A) The State has complied with all requirements and commitments pertaining to the area in the applicable implementation plan, and (B) no more than 1 exceedance of the national ambient air quality standard level for ozone has occurred in the area in the year preceding the Extension Year.” With regard to the first element, “applicable implementation plan” is defined in Section 302(q) of the CAA as, the portion (or portions) of the implementation plan, or most recent revision thereof, which has been approved under Section 110, or promulgated under Section 110(c), or promulgated or approved pursuant to regulations promulgated under Section 301(d) and which implements the relevant requirements of the CAA. The language in Section 181(a)(5)(B) reflects the form of the 1-hour ozone NAAQS, which is exceedance based and does not reflect the 1997 8-hour ozone NAAQS, which is concentration based. Because Section 181(a)(5)(B) does not reflect the form of the 8-hour NAAQS and application would produce an absurd result, EPA interprets this provision in a manner consistent with Congressional intent but reflecting the form of the 1997 8-hour NAAQS. Therefore, EPA adopted an interpretation of Sections 172(a)(2)(C) and 181(a)(5) that an area will be eligible for the first of the one-year extensions under the 8-hour NAAQS if, for the attainment year, the area's 4th highest daily 8-hour average is 0.084 ppm or less.[2]
                    
                     The area will be eligible for the second extension if the area's 4th highest daily 8-hour value averaged over both the original attainment year and the first extension year is 0.084 ppm or less. No more than 2 one-year extensions may be issued for a single nonattainment area. EPA interprets the CAA and implementing regulations to allow the granting of a one-year extension under the following minimum conditions: (1) The State requests a one-year extension; (2) all requirements and commitments in the EPA-approved SIP for the area have been complied with; and (3) the area has a 4th highest daily 8-hour average of 0.084 ppm or less for the attainment year (or an area's 4th highest daily 8-hour value averaged over both the original attainment year and the first extension year is 0.084 ppm or less, if 
                    ( print page 56945)
                    a second one-year extension is requested).[3] II. Today's Actions EPA is proposing to determine that Georgia has met the CAA requirements to obtain a one-year extension of the attainment date for the 1997 8-hour ozone NAAQS for the Atlanta Area. As a result, EPA is proposing to extend the Atlanta Area's attainment date from June 15, 2010, to June 15, 2011, for the 1997 8-hour ozone NAAQS. EPA's proposed action is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for 2009, and on EPA's preliminary determination that the State is meeting its federally-approved state implementation plan. If today's proposed action is finalized, the Atlanta Area's attainment date for the 1997 8-hour ozone NAAQS will be extended one-year from June 15, 2010, to June 15, 2011. III. EPA's Analysis of the State's Requests for an Attainment Date Extension for the Atlanta Area for the 1997 8-Hour Ozone NAAQS As was explained above in this rulemaking, EPA interprets the CAA and implementing regulations to allow the granting of a one-year extension under the following minimum conditions: (1) The State requests a one-year extension; (2) all requirements and commitments in the EPA-approved SIP for the area have been complied with; and (3) the area has a 4th highest daily 8-hour average of 0.084 ppm or less for the attainment year (or an area's 4th highest daily 8-hour value averaged over both the original attainment year and the first extension year is 0.084 ppm or less, if a second one-year extension is requested). Below provides EPA's analysis of how Georgia has met these minimum requirements. (1) The State Requests a One-Year Extension The State of Georgia, through GA DNR, submitted a letter on June 9, 2010, requesting that EPA grant a one-year extension of the attainment date for the 1997 8-hour ozone NAAQS for the Atlanta Area. The letter contained a certification that the State is complying with all requirements and commitments pertaining to the Atlanta Area in the applicable implementation plan; and that the Atlanta Area has a 4th highest daily 8-hour average of 0.084 ppm or less for the attainment year (
                    *i.e.,*
                     2009) for this initial request for an extension. EPA's analysis of the certification from Georgia, and of the ambient air quality monitoring data for the Atlanta Area for the 1997 8-hour ozone NAAQS (
                    *i.e.,*
                     in relation to the State's attainment date extension request) is provided below. (2) All Requirements and Commitments in the EPA-Approved SIP for the Area Have Been Complied With In the letter submitted by GA DNR, on June 9, 2010, the State discusses implementation of state measures in the SIP. One of the required elements for a one-year extension required under Section 181(a)(5) of the CAA is that the State has complied with all requirements and commitments pertaining to the area in the applicable implementation plan (as that term is defined in Section 302(q) of the CAA). EPA has conducted an independent review of whether Georgia is in compliance with the applicable implementation plan for the Atlanta Area as intended by Section 181(a)(5)(A) of the CAA, and has made the preliminary determination that the State is in compliance. This preliminary determination is based on EPA's belief that the state is currently meeting the EPA-approved state implementation plan for the Atlanta Area. On October 21, 2009, the State of Georgia submitted SIP revisions to address the requirements related to the 1997 8-hour ozone attainment demonstration for the Atlanta Area. Nonetheless, EPA does not and did not view submission or approval of this attainment demonstration as relevant for meeting the “applicable implementation plan” for the Atlanta Area with regard to Section 181(a)(5)(A) of the CAA. EPA is currently reviewing the approvability of this attainment demonstration submission and will make a final determination on the approvability through a separate rulemaking in the 
                    **Federal Register.** (3) The Area Has a 4th Highest Daily 8-Hour Average of 0.084 ppm or Less for the Attainment Year In the letter submitted by GA DNR, on June 9, 2010, the State has certified that the 4th highest daily 8-hour average ozone concentration for the Atlanta Area in 2009 was below 0.084 ppm, and that the 2009 ozone data which are included in EPA's Air Quality System (AQS) meets necessary quality control and quality assurance requirements.

 EPA has reviewed the 1997 8-hour ozone NAAQS ambient air quality monitoring data for the Atlanta Area, consistent with the requirements contained in 40 CFR part 50 and as recorded in the EPA AQS database. On the basis of that review, EPA has preliminarily concluded that for the attainment year, 2009, the Atlanta Area's 4th highest daily 8-hour average concentration was 0.077 ppm which is below the 8-hour ozone NAAQS of 0.08 ppm (effectively 0.084 ppm). Because the statutory provisions have been satisfied, EPA is proposing 
                    ( print page 56946)
                    approval of Georgia's attainment date extension request for the Atlanta Area for the 1997 8-hour ozone NAAQS. IV. Proposed Actions EPA is proposing to approve Georgia's June 9, 2010, request for EPA to grant a one-year extension (from June 15, 2010, to June 15, 2011) of the Atlanta Area attainment date for the 1997 8-hour ozone NAAQS because EPA believes that Georgia has met the statutory requirements for such an extension. EPA's belief is based on its preliminary determination that the state is in compliance of the requirements and commitments associated with the EPA-approved implementation plan, and on the belief that the 4th highest daily 8-hour ozone average concentration for 2009 for the Atlanta Area is below the 1997 8-hour ozone NAAQS as required by the CAA. As provided in 40 CFR 51.907, if EPA finalizes this action, it will extend, by one year, the deadline by which the Atlanta Area must attain the 1997 8-hour ozone NAAQS. It will also extend the timeframe by which EPA must make an attainment determination for the area. EPA notes that this proposed action only relates to the initial one- year extension. As noted in Section 181(a)(5) of the CAA, areas may qualify for up to 2 one-year extensions. If requested at a future date, EPA will make a determination of the appropriateness of a second one-year extension for the Atlanta Area for the 1997 8-hour ozone NAAQS in a separate rulemaking. V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve SIP submissions and requests that comply with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing the state's request for an extension of the 1997 8-hour ozone NAAQS attainment date for the Atlanta Area, EPA's role is to approve the state's request, provided that it meets the criteria of the CAA. Accordingly, this proposed action merely approves a state request for an extension of the 1997 8-hour ozone NAAQS attainment date 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 underExecutive 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Is not a significant regulatory action subject toExecutive 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, underExecutive Order 12898 (59 FR 7629, February 16, 1994). In addition, this proposed 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.

                         EPA issued a revised 8-hour ozone NAAQS in 2008. EPA subsequently reconsidered the 2008 NAAQS, and proposed a new 8-hour ozone NAAQS on January 19, 2010 (75 FR 2938). Final 8-hour ozone NAAQS are expected to be effective in October 2010. The current proposed action, however, is being taken with regard to the 1997 8-hour ozone NAAQS. Requirements for the Atlanta Area for the 2010 8-hour ozone NAAQS will be addressed in the future. Back to Citation
