Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Sacramento Metropolitan 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. The revisions concern negative declarations from the Sacramento Metropolitan Air Quality Management District (SMAQMD) and the Santa Barbara County Air Pollution Control District (SBCAPCD). The SMAQMD submitted negative declarations for two source categories that emit volatile organic compounds (VOC): Plastic Parts Coating: Business Machines and Plastic Parts Coating: Other. The SBCAPCD submitted negative declarations for six source categories that emit VOC: Industrial Wastewater, Plastic Parts Coating: Business Machines, Plastic Parts Coating: Other, Industrial Cleaning Solvents, Offset Lithography, and Shipbuilding Coatings. The SMAQMD and the SBCAPCD have certified that these source categories are not present in their respective Districts and this information is being added to the federally approved State Implementation Plan. The intended effect of approving these negative declarations is to meet the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). 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.
