Abstract
EPA is finalizing approval of revisions to the Pinal County portion of the Arizona State Implementation Plan (SIP). These revisions were proposed in the Federal Register on August 17, 2009 and concern particulate matter (PM) emissions from construction, earthmoving, and related activities, and commercial and residential unpaved parking lots. We are approving these local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
