Approval and Promulgation of State Implementation Plans; California State Implementation Plan Revision, Santa Barbara County, Ventura County, Monterey Bay Unified, and Placer County Air Pollution Control Districts; and Yolo-Solano Air Quality Management District

EPA is taking direct final action on revisions to the California State Implementation Plan (SIP). The revisions concern rules from the following districts: Santa Barbara County Air Pollution Control District (SBCAPCD), Ventura County Air Pollution Control District (VCAPCD), Monterey Bay Unified Air Pollution Control District (MBUAPCD), Yolo-Solano Air Quality Management District (YSAQMD), and Placer County Air Pollution Control District (PCAPCD). This approval action will incorporate these rules into the federally approved SIP. The intended effect of approving these rules is to regulate emissions of volatile organic compounds (VOCs) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). In addition, the final action on three of these rules, MBUAPCD's Rule 416, 433, and 434, serves as a final determination that the finding of nonsubmittal for the rules has been corrected and that on the effective date of this action, any Federal Implementation Plan (FIP) clock is stopped. The revised rules control VOC emissions from operations involving the following: the coating or assembly of aircraft or aerospace vehicle parts and products, the use of organic solvents and organic solvent cleaners, the coating of miscellaneous metal parts and products, the application of adhesives, and the coating of flat wood paneling. Thus, EPA is finalizing the approval of these revisions into the California SIP under provisions of the CAA regarding EPA action on SIP submittals, SIPs for national primary and secondary ambient air quality standards and plan requirements for nonattainment areas.
