EPA is taking final action to fully approve the operating permits programs submitted by the California Air Resources Board (CARB) on behalf of the following 34 air districts: Amador County Air Pollution Control District (APCD), Bay Area Air Quality Management District (AQMD), Butte County AQMD, Calaveras County APCD, Colusa County APCD, El Dorado County APCD, Feather River AQMD, Glenn County APCD, Great Basin Unified APCD, Imperial County APCD, Kern County APCD, Lake County AQMD, Lassen County APCD, Mariposa County APCD, Mendocino County APCD, Modoc County APCD, Mojave Desert AQMD, Monterey Bay Unified APCD, North Coast Unified AQMD, Northern Sierra AQMD, Northern Sonoma County APCD, Placer County APCD, Sacramento Metro AQMD, San Diego County APCD, San Joaquin Valley Unified APCD, San Luis Obispo County APCD, Santa Barbara County APCD, Shasta County APCD, Siskiyou County APCD, South Coast AQMD, Tehama County APCD, Tuolumne County APCD, Ventura County APCD, and Yolo-Solano AQMD. These programs were submitted in response to the directive in the 1990 Clean Air Act (CAA) Amendments that permitting authorities develop, and submit to EPA, programs for issuing operating permits to all major stationary sources and to certain other sources within the permitting authorities' jurisdiction. On the dates listed in Table 1 below, EPA granted interim approval to the 34 operating permits programs. All 34 air districts revised their programs to satisfy the conditions of the interim approval, and EPA proposed full approval in the Federal Register on the dates listed in Table 1. EPA received comments from several commenters on our proposed actions. After carefully reviewing and considering the issues raised by the commenters, EPA is taking final action to fully approve all 34 operating permits programs. EPA published 11 separate proposals to approve the 34 districts' title V operating permits programs. Today we are consolidating our final actions on those proposals into one final rule
