## Abstract

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the Mojave Desert Air Quality Management District (MDAQMD) and the Ventura County Air Pollution Control District (VCAPCD). 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 rules control VOC emissions from asphalt roofing operation, semiconductor manufacturing operations, and glycol dehydrators. 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.
