The Environmental Protection Agency (EPA) is determining that the Southeast Desert nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard. This determination is based on complete, quality-assured, and certified data for the most recent three-year period (2011-2013). Preliminary data available through December 2014 are consistent with continued attainment.
This final rule is effective on May 15, 2015.
The EPA has established a docket for this action, identified by Docket ID Number EPA-R09-OAR-2014-0612.

On August 25, 2014 (79 FR 50574), the EPA proposed to determine that the Southeast Desert 1-hour ozone nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard (NAAQS or “standard”), based on complete, quality-assured and certified ambient air quality data for the 2011 to 2013 monitoring period. The Southeast Desert 1-hour ozone nonattainment area covers the Victor Valley/Barstow region in San Bernardino County, the Coachella Valley region in Riverside County, and the Antelope Valley portion of Los Angeles County (see 40 CFR 81.305 for the precise boundaries of the 1-hour ozone nonattainment area).
Our proposed rule provides background information on the 1-hour ozone standard; the designations and classifications of the Southeast Desert under the Clean Air Act (CAA or “Act”) for the 1-hour ozone standard; EPA's prior determination that the Southeast Desert failed to attain the 1-hour ozone standard by the 2007 applicable attainment date based on 2005-2007 ozone data; and the recent request by the State of California to make a finding of attainment of the 1-hour ozone standard for the Southeast Desert in light of improved ozone conditions in the area. See 79 FR 50574, at 50575. We also described how we determine whether an area's air quality meets the 1-hour ozone standard; identified the relevant air monitoring agencies in the Southeast Desert and their respective ozone monitoring networks and monitoring network plans; and documented our previous review of the networks and network plans, the agencies' annual certifications of ambient air monitoring data, and our determination of completeness for 2011-2013 data from the eight monitoring sites within the Southeast Desert. See 79 FR 50574, at 50576. Please see our proposed rule for more information concerning these topics.
Our proposed rule included a table of “expected exceedences” for the Southeast Desert nonattainment area. See 79 FR 50574, at 50577. As explained in our proposed rule, an area is considered to have attained the 1-hour ozone standard if there are no violations of the standard, in accordance with 40 CFR 50.9 and based on three consecutive calendar years of complete, quality-assured and certified monitoring data. A violation occurs when the “expected number” of days per calendar year with maximum hourly average concentrations above 0.12 ppm is greater than one (1.0) at any site in the area, when averaged over three consecutive calendar years. 1
An exceedance occurs when the maximum hourly ozone concentration during any day exceeds 0.124 ppm. For more information, please see “National 1-hour primary and secondary ambient air quality standards for ozone” (40 CFR 50.9) and “Interpretation of the 1-Hour Primary and Secondary National Ambient Air Quality Standards for Ozone” (40 CFR part 50, appendix H). Based on our review of the monitoring data, and taking into account the extent and reliability of the applicable ozone monitoring network, we proposed to determine that the Southeast Desert has attained the 1-hour ozone standard based on complete, certified and quality-assured data for the 2011-2013 period. In our proposed rule, we indicated that we would review preliminary data for 2014 prior to taking final action. We have now done so and find that preliminary data for 2014, from January through December, for the ozone monitoring sites in the Southeast Desert are consistent with continued attainment.

III. Final Action
EPA is determining that the Southeast Desert nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard, based on complete, quality-assured and certified ambient air quality monitoring data for the 2011 to 2013 monitoring period. Preliminary data available for 2014, from January through December, are consistent with continued attainment.
IV. Statutory and Executive Order Reviews
This action makes a determination based on air quality data 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 it will not impose substantial direct costs on tribal governments or preempt tribal law.
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register . A major rule cannot take effect until 60 days after it is published in the Federal Register . This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by June 15, 2015. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements (see section 307(b)(2)).
