 Environmental Protection Agency 40 CFR Part 52
[EPA-R07-OAR-2010-0416; FRL-9271-8]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Proposed rule.
 SUMMARY: EPA is proposing to determine that the St. Louis (MO-IL) metropolitan nonattainment area has attained the 1997 8-hour National Ambient Air Quality Standard (NAAQS) for ozone. The St. Louis metropolitan ozone nonattainment area includes the counties of Franklin, Jefferson, St. Charles, and St. Louis as well as St. Louis City in Missouri; and the counties of Madison, Monroe, St. Clair, and Jersey in Illinois. This proposed determination is based on three years of complete, quality assured ambient air quality monitoring data for Missouri and Illinois for the 2008 through 2010 ozone seasons showing attainment of the NAAQS at all ozone monitoring sites in the nonattainment area. If EPA finalizes its proposed determination, it will suspend the obligation to submit certain ozone attainment demonstration requirements, along with other requirements related to the attainment of the 1997 8-hour ozone standard.
 DATES: Comments must be received on or before March 30, 2011.

Explain why you agree or disagree; suggest alternative and substitute language for your requested change. 4. Describe any assumptions and provide any technical information and/or data you used. 5. If you estimate potential cost or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced. 6. Provide specific examples to illustrate your concerns, and suggest alternatives. 7. Explain your views as clearly as possible, avoiding the use of profanity or personal threats. 8. Make sure to submit your comments by the comment period deadline identified in the proposed rule. II. What action is EPA proposing to take? EPA is proposing to determine that the St. Louis (MO-IL) metropolitan 1997 8-hour ozone nonattainment area has attained the 1997 8-hour ozone NAAQS. EPA received a request from the Missouri Department of Natural Resources to determine that the St. Louis metropolitan nonattainment area has attained the 1997 8-hour ozone standard of 0.08 parts per million (ppm). This request is based upon the most recent three years of complete, quality assured ambient air monitoring data for Missouri and Illinois showing that the area has attained the NAAQS during the 2008-2010 monitoring period. On March 27, 2008 (73 FR 16436), EPA promulgated a revised 8-hour ozone standard of 0.075 ppm. On January 6, 2010, EPA again addressed this 2008 revised standard and proposed to set the primary 8-hour ozone standard within the range of 0.060 to 0.070 ppm, rather than at 0.075 ppm. EPA is working to complete reconsideration of the standard and thereafter will proceed with designations. Today's proposed rulemaking relates only to a determination of attainment for the 1997 8-hour ozone standard and is not affected by the ongoing process of reconsidering the revised 2010 standard. The monitors and design values are displayed in Table 1. The table summarizes the annual fourth-high daily maximum 8-hour ozone concentrations and their 3-year (2008-2010) averages for all monitors in the St. Louis (MO-IL) metropolitan nonattainment area. These data reflect peak ozone concentrations quality assured and reported by the States of Illinois and Missouri.

 Review of the 2008-2010 ozone monitoring data in the nonattainment area shows that all sites were attaining the 1997 8-hour ozone NAAQS during this period. Therefore, based on the most recent three years of complete, quality assured ozone monitoring data, EPA is proposing to determine that the 1997 8-hour ozone standard has been attained in the St. Louis (MO-IL) metropolitan ozone nonattainment area. III. What is the effect of this action? EPA is proposing to determine that the St. Louis metropolitan 8-hour ozone nonattainment area consisting of both the Missouri and Illinois portions of the area has attained the 1997 8-hour ozone standard. As provided in 40 CFR 51.918, if EPA finalizes this determination, certain attainment demonstration requirements and associated reasonably available control measures, reasonable further progress plans, contingency measures, and other planning SIP requirements related to attainment of the 8-hour ozone NAAQS shall be suspended as to the St. Louis nonattainment area. Under 40 CFR 51.918, a final determination that the area has met the 1997 8-hour ozone standard suspends the State's obligation to submit requirements related to attainment, for so long as the area continues to attain the standard. This action does not constitute a redesignation to attainment under CAA section 107(d)(3), because Missouri and Illinois do not have approved maintenance plans as required under section 175A of the CAA, nor has EPA made a determination that the area has met the other requirements for redesignation. The ozone classification and designation status of the area remains moderate nonattainment for the 1997 8-hour ozone NAAQS until such time as a redesignation request and maintenance plan are submitted to EPA and EPA determines that it meets the CAA requirements for redesignation to attainment. If EPA subsequently determines, after notice-and-comment rulemaking in the 
                    **Federal Register**
                    , that the area has violated the 1997 8-hour ozone standard, the basis for the suspension of these requirements would no longer exist, and the area would thereafter have to address the pertinent requirements. IV. EPA's proposed action? EPA is proposing to determine that the St. Louis (MO-IL) metropolitan 1997 8-hour ozone nonattainment area has attained the 1997 8-hour ozone standard based on three years of complete, quality assured ambient air quality monitoring data for Missouri and Illinois for the 2008-2010 ozone seasons. As provided in 40 CFR 51.918, if EPA finalizes this determination, the requirements for Missouri and Illinois to submit an attainment demonstration and associated reasonably available control measures, a reasonable further progress plan, and contingency measures under section 172(c)(9), and any other planning SIP related to attainment of the 1997 8-hour ozone NAAQS for the St. Louis Metropolitan area would be suspended. This suspension of requirements would be effective as long as the area continues to attain the 1997 8-hour ozone standard. This action addresses only the 1997 8-hour ozone standard of 0.08 ppm, and does not address any subsequent revisions to the standard. V. Statutory and Executive Order Reviews This action proposes to make a determination based on air quality data, and would, if finalized, result in the suspension of certain Federal Requirements. Accordingly, this proposed action does not impose additional requirements beyond those imposed by State law. Therefore, 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 Clean Air Act; 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 8-hour ozone clean NAAQS data determination for the St. Louis (MO-IL) metropolitan 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.
