Abstract
EPA is finalizing approval of revisions to the Maricopa County Air Quality Department (MCAQD) portion of the Arizona State Implementation Plan (SIP). These revisions were proposed in the Federal Register on April 16, 2010 and concern opacity standards related to multiple pollutants, including particulate matter (PM) emissions from several different types of sources, ranging from fugitive dust to diesel generators. We are approving a local rule that regulates these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
