## Abstract

EPA is taking direct final action on revisions to the California State Implementation Plan (SIP). The revisions concern rule rescissions from the Sacramento Metropolitan Air Quality Management District (SMAQMD), San Diego County Air Pollution Control District (SDCAPCD), San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), and amendments to Ventura County Air Pollution Control District (VCAPCD). This approval action will rescind and amend these rules from the federally approved SIP. The intended effect of approving these rule rescissions and amendments is to update and clarify the State Implementation Plan in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The rule rescissions consist of obsolete rules that have been superseded or removed from the district's regulations. EPA is finalizing the approval of these revisions to the California SIP under provisions of the CAA regarding EPA action on SIP submittals, SIP requirements for national primary and secondary ambient air quality standards and plan requirements for nonattainment areas.
