## Abstract

EPA is finalizing a limited approval and limited disapproval of a revision to the Maricopa County Environmental Services Department (MCESD) portion of the Arizona State Implementation Plan (SIP) concerning particulate matter (PM-10) emissions from open outdoor fires. 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 Arizona State to correct rule deficiencies. EPA is also finalizing a limited approval and a full approval of revisions to the MCESD portion of the Arizona SIP concerning PM-10 emissions from abrasive blasting and non-metallic mineral mining and processing, respectively. The limited approval notifies Arizona State that there are rule deficiencies. These actions were proposed in the Federal Register on July 11, 2000.
