I. Summary of Today's Final Action

EPA is approving several related actions. First, under Clean Air Act (CAA or “Act”) section 110(k)(3), EPA is approving a maintenance plan for the 1997 8-hour ozone standard (“San Diego 8-hour maintenance plan”) for the San Diego County 1997 ozone nonattainment area (“San Diego 8-hour area”) as a revision to the California state implementation plan (SIP). (1) The San Diego 8-hour maintenance plan is included in a document titled Redesignation Request and Maintenance Plan for the 1997 National Ozone Standard for San Diego County (December 2012) submitted by the California Air Resources Board (CARB) on December 28, 2012.

In connection with the San Diego 8-hour maintenance plan, EPA finds that the maintenance demonstration showing how the area will continue to attain the 1997 8-hour ozone national ambient air quality standard (1997 ozone NAAQS or 1997 ozone standard) for at least 10 years beyond redesignation (i.e., through 2025) and the contingency provisions describing the actions that the San Diego County Air Pollution Control District (SDCAPCD) will take in the event of a future monitored violation meet all applicable requirements for maintenance plans and related contingency provisions in CAA section 175A. EPA is also approving the motor vehicle emissions budgets (MVEBs) in the San Diego 8-hour maintenance plan because we find that they meet the applicable transportation conformity requirements under 40 CFR 93.118(e).

Second, under CAA section 107(d)(3)(D), EPA is approving CARB's request that accompanied the submittal of the San Diego 8-hour maintenance plan, that is, to redesignate the San Diego 8-hour area to attainment for the 1997 ozone standard. We are doing so based on our conclusion that the area has met the five criteria for redesignation under CAA section 107(d)(3)(E). Our conclusion in thisregard is based on our determination that the area has attained the 1997 ozone standard; that relevant portions of the California SIP are fully approved; that the improvement in air quality is due to permanent and enforceable reductions in emissions; that California has met all requirements applicable to the San Diego 8-hour area with respect to section 110 and part D of the CAA; and is based on our approval of the San Diego 8-hour maintenance plan, which is part of this action.

II. Background

On March 25, 2013 (78 FR 17902), EPA issued a notice of rulemaking proposing to approve California's request to redesignate the San Diego County area to attainment for the 1997 8-hour ozone standard, as well as proposing to approve California's ten-year ozone maintenance plan for the area, and the volatile organic compound (VOC) and oxides of nitrogen (NO X) MVEBs, and VOC and NO X emission inventories as revisions of the California SIP. (2) The proposed rulemaking set forth the basis for determining that California's redesignation request meets the CAA requirements for redesignation for the 1997 8-hour ozone NAAQS. The proposed rulemaking provided an extensive background on the ozone standards and their relationship to historical air quality in San Diego County. The proposed rulemaking also described the complete, quality-assured air quality monitoring data for San Diego County for 2009-2011 showing that this area attained the 1997 8-hour ozone NAAQS. Preliminary data available to date for 2012 are consistent with continued attainment of the 1997 8-hour ozone NAAQS.

III. What comments did EPA receive on the proposed rule?

EPA's proposed rule provided a 30-day public comment period. During this period, we received comment letters from the United States Department of the Navy and the Industrial Environmental Association in support of EPA's March 25, 2013, proposed rule. During the public comment period, we did not receive any comments opposing the proposed rule.

IV. What actions is EPA taking?

Under CAA section 110(k)(3), and for the reasons provided in the proposed rule and summarized herein, EPA is approving CARB's submittal dated December 28, 2012 of the Redesignation Request and Maintenance Plan for the 1997 National Ozone Standard for San Diego County (December 2012) as a revision to the California state implementation plan (SIP). In connection with the San Diego 8-hour maintenance plan, EPA finds that the maintenance demonstration showing how the area will continue to attain the 1997 8-hour ozone NAAQS for 10 years beyond redesignation (i.e., through 2025) and the contingency provisions describing the actions that SDCAPCD and CARB will take in the event of a future monitored violation meet all applicable requirements for maintenance plans and related contingency provisions in CAA section 175A. EPA is approving the MVEBs in the San Diego 8-hour maintenance plan (shown in table 7 of this document) because we find they meet the applicable transportation conformity requirements under 40 CFR 93.118(e).

Second, under CAA section 107(d)(3)(D), we are approving CARB's request, which accompanied the submittal of the maintenance plan, to redesignate the San Diego County 8-hour ozone nonattainment area to attainment for the 1997 8-hour ozone NAAQS. We are doing so based on our conclusion that the area has met the five criteria for redesignation under CAA section 107(d)(3)(E). Our conclusion in this regard is in turn based on our determination that the area has attained the 1997 ozone NAAQS; that relevant portions of the California SIP are fully approved; that the improvement in air quality is due to permanent and enforceable reductions in emissions; that California has met all requirements applicable to the San Diego 8-hour area with respect to section 110 and part D of the CAA; and is based on our approval of the San Diego 8-hour maintenance plan, which is part of this action.

V. Statutory and Executive Order Reviews

Under the CAA, redesignation of an area to attainment and the accompanying approval of a maintenance plan under section 107(d)(3)(E) are actions that affect the status of a geographical area and do not impose any additional regulatory requirements on sources beyond those imposed by State law. Redesignation to attainment does not in and of itself create any new requirements, but rather results in the applicability of requirements contained in the CAA for areas that have been redesignated to attainment. Moreover, 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 Clean Air Act. Accordingly, these actions merely approve a State plan and redesignation request as meeting federal requirements and do not impose additional requirements beyond those by state law. For these reasons, these actions:

  • Are 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);
  • Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • Are 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.);
  • Do 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);
  • Do not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • Are not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • Are not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • Are 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
  • Do not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, 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. Nonetheless, in accordance with EPA's 2011 Policy on Consultation and Coordination with Tribes, EPA hasnotified Tribes located within the San Diego County 8-hour ozone nonattainment.

Footnotes

(1) On March 27, 2008 (73 FR 16436), EPA promulgated a revised 8-hour ozone standard of 0.075 ppm (the 2008 8-hour ozone standard), and on May 21, 2012, EPA designated San Diego County as nonattainment for the 2008 8-hour ozone standard (77 FR 30088). This rulemaking relates only to the 1997 8-hour ozone standard and does not relate to the 2008 8-hour ozone standard.

(2) Ground-level ozone is generally not emitted directly by sources. Rather, directly-emitted NO X and VOC react in the presence of sunlight to form ground-level ozone, as a secondary pollutant, along with other secondary compounds. NO X and VOC are “ozone precursors.” Reduction of peak ground-level ozone concentrations is typically achieved through controlling VOC and NO X emissions.
