Abstract
EPA is finalizing approval of revisions to the Maricopa County portion of the Arizona State Implementation Plan (SIP). These revisions were proposed in the Federal Register on September 2, 2010 and concern particulate matter (PM) emissions from fugitive dust sources such as construction sites and related activities, unpaved roads, unpaved parking lots, and disturbed soils on vacant lots. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
