ENVIRONMENTAL PROTECTION AGENCY 40 CFR Parts 52 and 81 [CA-64-1-6997; FRL-5202-4] Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; State of California, Approval of the Maintenance Plan for the San Francisco Bay Area and Redesignation of the San Francisco Bay Area to Attainment; Approval of Emissions Inventory; Approval of NOXExemption Petition AGENCY: Environmental Protection Agency (EPA). ACTION: Final rule.
SUMMARY: The EPA is approving a redesignation request and maintenance plan for the San Francisco Bay Area as a revision to California's State Implementation Plan (SIP) for ozone. In addition, EPA is approving the 1990 base year emissions inventory and a petition requesting an exemption from the section 182(f) nitrogen oxides (NOX) requirements for the area.
On April 13, 1994, EPA notified the State of California that EPA had made a finding of incompleteness for required programs under the Clean Air Act (CAA or the Act). The EPA's redesignation of the San Francisco Bay Area to attainment and approval of the 1990 emissions inventory abrogates those requirements for the area. Therefore, the sanctions and federal implementation plan clocks begun by those findings are stopped at the time of this redesignation. EFFECTIVE DATE: This final rule will become effective on June 21, 1995.

SUPPLEMENTARY INFORMATION: Background A. Ozone Redesignation Request and Maintenance Plan The San Francisco Bay Area ozone nonattainment area has attained the National Ambient Air Quality Standard (NAAQS) for ozone based on three years of quality assured ambient air quality data, for the period 1990-1992. Therefore, in accordance with the CAA, as amended in 1990, and to ensure continued attainment of the standard for at least 10 years, the State of California has submitted an ozone maintenance plan which projects continued attainment of the ozone NAAQS in the San Francisco Bay Area.
The maintenance plan submitted for the San Francisco Bay Area meets all applicable requirements of the CAA. The San Francisco Bay Area submittal complies with section 175A of the Act which sets forth maintenance plan requirements for areas seeking redesignation from nonattainment to attainment. The plan demonstrates attainment of the NAAQS for at least 10 years after the area is redesignated. Eight years after the redesignation, the state commits to submit a revised maintenance plan which demonstrates attainment for the ten year period following the initial ten year period. In the event of a NAAQS violation, the maintenance plan contains contingency measures adequate to ensure prompt correction of the air quality problem. The state submittal being approved today contains a redesignation request in which the state demonstrates that the area has fulfilled the redesignation requirements of the CAA pursuant to section 107(d)(3)(E), a NOXexemption petition pursuant to section 182(f), and a 1990 emissions inventory of ozone precursors pursuant to section 182(a) for the area.
On September 28, 1994 (59 FR 49361-49370), EPA published a notice of proposed rulemaking (NPRM) for the State of California SIP. The NPRM proposed that the San Francisco Bay Area be redesignated from nonattainment to attainment for ozone and that the maintenance plan submitted by the State of California as a revision to the California SIP be approved contingent upon EPA taking final rulemaking action to approve various SIP deficiencies for the San Francisco Bay Area (including volatile organic compound (VOC) reasonable available control technology (RACT) corrections, emission statement rule, NSR corrections) and California's submittal of the ozone maintenance plan amendments to the contingency plan and the 1990 base year emissions inventory. In addition, the NPRM proposed approval of a NOXwaiver petition and 1990 base year emissions inventory. Since that time, the EPA has taken final rulemaking action to approve both the volatile organic compound (VOC) reasonable available control technology (RACT) rules which resolve the deficiencies and the emission statement rule. Below is the list of rules that the EPA has approved since the time of proposed rulemaking on the redesignation. These approvals remove one of the conditions for redesignation of the San Francisco Bay Area.
