## Abstract

EPA is taking direct final action to approve revisions to the California State Implementation Plan (SIP) which concern the control of particulate matter (PM) emissions from open burning, incinerator burning, and orchard heater sources in the Kern County Air Pollution Control District (KCAPCD), Northern Sierra Air Quality Management District (NSAQMD), San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), Siskiyou County Air Pollution Control District (SCAPCD), Tehama County Air Pollution Control District (THCAPCD), and Tuolumne County Air Pollution Control District (TOCAPCD). This approval action will incorporate these rules into the federally-approved SIP. The intended effect of this action 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.
