## Abstract

EPA is finalizing a limited approval and limited disapproval of a revision to the Pinal County Air Quality Control District portion of the Arizona State Implementation Plan (SIP). This action was proposed in the Federal Register on June 18, 2001 and concerns particulate matter (PM) emissions from stationary sources. 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 to correct rule deficiencies.
