Abstract
EPA is taking direct final action to approve a revision to the Maricopa County portion of the Arizona State Implementation Plan (SIP). This revision concerns reductions of particulate matter (PM) emissions from the paving of unpaved roads and the use of these reductions to satisfy the offset requirements under the new source review provisions of the Clean Air Act as amended in 1990 (CAA or the Act). We are approving a local rule which assures that the PM emission reductions resulting from the road paving meet the criteria for valid offsets under the Act.
