Abstract
EPA is finalizing approval of revisions to the Maricopa Air Quality Department (MCAQD) portion of the Arizona State Implementation Plan (SIP). These revisions were proposed in the Federal Register on August 26, 2009 and concern particulate matter (PM) emissions from non- metallic mineral mining and processing in the Maricopa County (Phoenix) serious PM-10 nonattainment area. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
