Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, South Coast Air Quality Management District and Santa Barbara County Air Pollution Control District

EPA is taking direct final action on revisions to the California State Implementation Plan (SIP). The revisions concern rules from the following districts: South Coast Air Quality Management District (SCAQMD) and Santa Barbara County Air Pollution Control District (SBAPCD). 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 these rules serves as a final determination that the deficiencies in these rules have been corrected and that on the effective date of this action, any sanctions or Federal Implementation Plan (FIP) obligations are permanently stopped. The revised rules control VOC emissions from marine coating operations, coating of metal parts and products, motor vehicle assembly line coating operations, solvent cleaning operations, architectural coatings, and motor vehicle and mobile equipment coating operations. 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.
