## Abstract

EPA is taking direct final action to approve revisions to the California State Implementation Plan. The revisions concern rules from the following: South Coast Air Quality Management District (SCAQMD) and Yolo-Solano Air Quality Management District (YSAQMD). 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 organic liquid loading, pharmaceutical and cosmetics manufacturing operations, and polyester resin 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.
