## Abstract

EPA is finalizing a limited approval and limited disapproval of revisions to the Maricopa County Environmental Services Department portion of the Arizona State Implementation Plan (SIP) and the Bay Area Air Quality Management District portion of the California SIP. This action was proposed in the Federal Register on June 5, 2002, and concerns volatile organic compound (VOC) emissions from solvent cleaning operations. 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 Arizona and California to correct rule deficiencies.
