Revisions to the California State Implementation Plan, Placer County Air Pollution Control District

EPA is finalizing a limited approval and limited disapproval of revisions to the Placer County Air Pollution Control District (PCAPCD) portion of the California State Implementation Plan (SIP). This action was proposed in the Federal Register on September 6, 2011 and concerns oxides of nitrogen (NOX) emissions from biomass fuel-fired boilers. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), this action simultaneously approves a local rule that regulates these emission sources and directs California to correct rule deficiencies.
