Revisions to the California State Implementation Plan, Imperial County Air Pollution Control District, Monterey Bay Unified Air Pollution Control District, San Joaquin Valley Unified Air Pollution Control District, and South Coast Air Quality Management District

EPA is finalizing a limited approval and limited disapproval of revisions to the Imperial County Air Pollution Control District (ICAPCD) portion and Monterey Bay Unified Air Pollution Control District (MBUAPCD) portion of the California State Implementation Plan (SIP). This action was proposed in the Federal Register on December 15, 2000 and concerns PM-10 emissions from livestock feed lots and from agricultural burning. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), this action simultaneously approves local rules that regulate these emission sources and directs California to correct rule deficiencies. EPA is also finalizing full approval of revisions to the ICAPCD portion of the California SIP concerning definitions, PM-10 emissions from orchard heaters, incinerators, open burning, and range improvement burning; to the South Coast Air Quality Management District (SCAQMD) portion concerning PM-10 emissions from restaurant operations; and to the MBUAPCD portion concerning exceptions to other rules. EPA is deferring to a separate action revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) portion of the California SIP concerning PM-10 emissions from industrial processes and from residential wood combustion.
