## Abstract

Pursuant to the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is approving a revision to the Payson portion of the Arizona State Implementation Plan (SIP) submitted by the Arizona Department of Environmental Quality on January 23, 2012. This revision consists of the second ten-year maintenance plan for the Payson air quality planning area for the national ambient air quality standards (NAAQS) for particulate matter less than 10 microns in diameter (PM<INF>10</INF>). EPA is approving this plan based on the conclusion that the plan adequately provides for continued maintenance of the PM<INF>10</INF> NAAQS in the Payson area through 2022. EPA is taking this action pursuant to those provisions of the CAA that obligate the Agency to take action on submittals of revisions to SIPs. The effect of this action is to make the State's continuing commitments with respect to maintenance of the PM<INF>10</INF> NAAQS in the Payson area federally enforceable for another ten years.
