## Abstract

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the following: Kern County Air Pollution Control District (KCAPCD), Lake County Air Quality Management District (LCAQMD), Modoc County Air Pollution Control District (MCAPCD), Northern Sierra Air Quality Management District (NSAQMD), San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), and Ventura County Air Pollution Control District (VCAPCD). The rules control particulate matter (PM) emissions from open burning, orchard heaters, fuel burning equipment, or processes identified by a weight rate throughput. This approval action will incorporate these rules into the federally-approved SIP. The intended effect of approving these rules is to regulate emissions of PM in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA). Thus, EPA is finalizing the approval of these rules 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 attainment and nonattainment areas.
