Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Lake County Air Quality Management District and San Joaquin Valley Unified Air Pollution Control District

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the following: Lake County Air Quality Management District (LCAQMD) and San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). The rules control particulate matter (PM) emissions from open burning 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.
