 Environmental Protection Agency 40 CFR Part 52
[EPA-R04-OAR-2010-1036-201062; FRL-9286-5]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Proposed rule.
 SUMMARY: EPA is proposing to determine that the Atlanta, Georgia nonattainment area has attained the 1997 8-hour ozone national ambient air quality standards (NAAQS) based on quality assured, quality controlled monitoring data from 2008-2010. The Atlanta, Georgia 1997 8-hour ozone nonattainment area (hereafter referred to as the “Atlanta Area”) is comprised of Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, Dekalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding and Walton Counties in Georgia. If this proposed determination is made final, the requirement for the State of Georgia to submit an attainment demonstration and associated reasonably available control measures (RACM) analysis, a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the 1997 8-hour ozone NAAQS for the Atlanta, Georgia 8-hour ozone nonattainment area, shall be suspended for as long as the Atlanta Area continues to meet the 1997 8-hour ozone NAAQS.
 DATES: Written comments must be received on or before April 25, 2011.

SUPPLEMENTARY INFORMATION: I. What action is EPA taking? II. What is the effect of this action? III. What is the background for this action? IV. What is EPA's analysis of the relevant air quality data? V. Proposed Action VI. Statutory and Executive Order Reviews I. What action is EPA taking? EPA is proposing to determine that the Atlanta Area has attained the 1997 8-hour ozone NAAQS. Today's proposal is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for the years 2008-2010 showing that the Atlanta Area has monitored attainment of the 1997 8-hour ozone NAAQS. EPA is in the process of establishing a new 8-hour ozone NAAQS, and expects to finalize the reconsidered NAAQS by July 2011. Today's action, however, relates only to the 1997 8-hour ozone NAAQS. Requirements for the Atlanta Area under the 2011 NAAQS will be addressed in the future. II. What is the effect of this action? If this determination is made final, under the provisions of EPA's ozone implementation rule (
                    *see*40 CFR 51.918), it would suspend the requirement to submit an attainment demonstration and associated RACM analysis, RFP plan, contingency measures,[1]
                    
                     and any other planning SIPs related to attainment of the 1997 8-hour ozone NAAQS. The attainment determination would continue until such time, if any, that EPA subsequently determines that the Atlanta Area has violated the 1997 8-hour ozone NAAQS. This determination is separate from any future designation determination or requirements for the Atlanta Area based on the revised or reconsidered ozone NAAQS, and would remain in effect regardless of whether EPA designates the Atlanta Area as a nonattainment area for purposes of a future revised or reconsidered 8-hour ozone NAAQS.[2]
                    
                     Furthermore, as described below, a final clean data determination is not equivalent to the redesignation of the Atlanta Area to attainment for the 1997 8-hour ozone NAAQS. If this rulemaking is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the 
                    **Federal Register**
                    , that the Atlanta Area has violated the 1997 8-hour ozone NAAQS, the basis for the suspension of the specific requirements, set forth at 40 CFR 51.918, would no longer exist, and the Atlanta Area would thereafter have to address pertinent requirements. As mentioned above, the determination that EPA proposes with this 
                    **Federal Register**
                     notice is not equivalent to a redesignation of the Atlanta Area to attainment. Finalizing this proposed action would not constitute a redesignation of the Area to attainment of the 1997 8-hour ozone NAAQS under section 107(d)(3) of the CAA. Further, finalizing this proposed action does not involve approving a maintenance plan for this Area as required under section 175A of the CAA, or affirm that the Area has met all other requirements for redesignation. The designation status of the Atlanta Area would remain nonattainment for the 1997 8-hour ozone NAAQS until such time as EPA determines that it meets the CAA requirements for redesignation to attainment. The State of 
                    ( print page 16720)
                    Georgia is currently working on a redesignation request and maintenance plan to change the Atlanta Area's status from nonattainment to attainment for the 1997 8-hour ozone NAAQS. EPA will consider Georgia's redesignation request and maintenance plan for the Atlanta Area in a rulemaking separate from today's proposed action. This proposed action, if finalized, is limited to a determination that the Atlanta Area has attained the 1997 8-hour ozone NAAQS. The 1997 8-hour ozone NAAQS became effective on July 18, 1997 (62 FR 38894), and are set forth at 40 CFR 50.10. On March 12, 2008, EPA promulgated revised 8-hour ozone NAAQS. Subsequently, on January 19, 2010, EPA published a proposed rule to reconsider the 2008 8-hour ozone NAAQS (75 FR 2938) and to propose a revised ozone NAAQS. EPA has not yet made any designation determinations for the Atlanta Area based on the revised 2008 8-hour ozone NAAQS. Today's proposed determination for the Atlanta Area, and any final determination, will have no effect on, and is not related to, any future designation determination that EPA may make based on the revised or reconsidered ozone NAAQS for the Atlanta Area. If this proposed determination is made final and the Atlanta Area continues to demonstrate attainment with the 1997 8-hour ozone NAAQS, the obligation for the State of Georgia to submit for the Atlanta Area an attainment demonstration and associated RACM analysis, RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 8-hour ozone NAAQS will remain suspended regardless of whether EPA designates the Atlanta Area as a nonattainment area for purposes of the revised or reconsidered ozone NAAQS. Once the Atlanta Area is designated for the revised or reconsidered ozone NAAQS, it will have to meet all applicable requirements for that designation. III. What is the background for this action? On July 18, 1997 (62 FR 38894), EPA promulgated a revised 8-hour ozone NAAQS of 0.08 parts per million (ppm) for both the primary and secondary standards. These NAAQS are more stringent than the previous 1-hour ozone NAAQS. Under EPA regulations at 40 CFR part 50, the 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 concentration is less than or equal to 0.08 ppm (
                    *i.e.,*
                     0.084 ppm when rounding is considered). 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. Specifically, section 2.3 of 40 CFR part 50, Appendix I, 
                    *“Comparisons with the Primary and Secondary Ozone Standards”*
                     states: The primary and secondary ozone ambient air quality standards are met at an ambient air quality monitoring site when the 3-year average of the annual fourth-highest daily maximum 8-hour average ozone concentration is less than or equal to 0.08 ppm. The number of significant figures in the level of the standard dictates the rounding convention for comparing the computed 3-year average annual fourth-highest daily maximum 8-hour average ozone concentration with the level of the standard. The third decimal place of the computed value is rounded, with values equal to or greater than 5 rounding up. Thus, a computed 3-year average ozone concentration of 0.085 ppm is the smallest value that is greater than 0.08 ppm. On April 30, 2004 (69 FR 23857), EPA published its air quality designations and classifications for the 1997 8-hour ozone NAAQS based upon air quality monitoring data from those monitors for calendar years 2001-2003. These designations became effective on June 15, 2004. The Atlanta Area is comprised of Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, Dekalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding, and Walton Counties; and was designated nonattainment for the 1997 8-hour ozone NAAQS (
                    *see*40 CFR part 81). IV. What is EPA's analysis of the relevant air quality data? EPA has reviewed the three most recent years of complete, certified, quality assured and quality controlled ambient air monitoring data for the 1997 8-hour ozone NAAQS, consistent with the requirements contained in 40 CFR part 50, as recorded in the EPA Air Quality System (AQS) database for the Atlanta Area. Based on that review, EPA has preliminarily concluded that the Atlanta Area attained the 1997 8-hour ozone NAAQS during the 2008-2010 monitoring period. Under EPA regulations at 40 CFR 50.10, the 1997 8-hour primary and secondary ozone ambient air quality NAAQS are met at an ambient air quality monitoring site when the three-year average of the annual fourth-highest daily maximum 8-hour average concentration is less than or equal to 0.08 ppm, as determined in accordance with Appendix I of 40 CFR part 50. Table 1 shows the design values (the metrics calculated in accordance with 40 CFR part 50, Appendix I, for determining compliance with the NAAQS) for the 1997 8-hour ozone NAAQS for the Atlanta Area monitors for the years 2008-2010. Table 2 shows the data completeness percentages for the 1997 8-hours ozone NAAQS for the Atlanta Area monitors for the years 2008-2010.

 EPA's review of these data indicate that the Atlanta Area has met and continues to meet the 1997 8-hour ozone NAAQS. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action. V. Proposed Action EPA is proposing to determine that the Atlanta, Georgia 1997 8-hour nonattainment area has attained the 1997 8-hour ozone NAAQS based on 2008-2010 complete, quality-assured, quality-controlled and certified monitoring data. As provided in 40 CFR 51.918, if EPA finalizes this determination, it would suspend the requirements for the State of Georgia to submit, for the Atlanta Area, an attainment demonstration and associated RACM analysis, RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 8-hour ozone NAAQS as long as the Area continues to attain the 1997 8-hour ozone NAAQS. VI. Statutory and Executive Order Reviews This action proposes to make a determination of attainment based on air quality, and would, if finalized, result in the suspension of certain federal requirements, and it would 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 1997 8-hour ozone NAAQS data determination for 
                    ( print page 16722)
                    the Atlanta Area 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.
