Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Kern County Air Pollution Control District, Placer County Air Pollution Control District, Ventura County Air Pollution Control District, and San Joaquin Valley Unified 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: Kern County Air Pollution Control District (KNCAPCD), Placer County Air Pollution Control District (PLCAPCD), Ventura County Air Pollution Control District (VTCAPCD), and San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). 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). The revised rules control VOC emissions from surface coating of metal parts and products, semiconductor manufacturing, fugitive emissions of reactive organic compounds (ROC) at petroleum refineries and chemical plants, polyester resin material operations, and decontamination of soil. 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.
