## Abstract

EPA is taking final action to approve a revision to the Alabama State Implementation Plan (SIP), submitted by the Alabama Department of Environmental Management (ADEM), on January 10, 2012, for parallel processing. ADEM submitted the final version of the SIP revision on March 2, 2012. The revision modifies Alabama's SIP to move Chapter 335-3-20 "Control of Fuels," which includes the regulation that governs the State's 7.0 pounds per square inch (psi) requirement for the low-Reid Vapor Pressure (RVP) fuel program in Jefferson and Shelby Counties (hereafter referred to as the "Birmingham Area") from the active measures portion of the Alabama SIP to the contingency measures portions of the maintenance plans for the Birmingham Area for the ozone national ambient air quality standards (NAAQS or standards), and of the proposed maintenance plans for the 1997 annual fine particulate matter (PM<INF>2.5</INF>) standards, and the 2006 24-hour PM<INF>2.5</INF> standards, when those actions are finalized. The change to the SIP will result in the federal RVP requirement of 7.8 psi applying for the Birmingham Area. EPA is approving this SIP revision because the State has demonstrated that it is consistent with section 110 of the Clean Air Act (CAA or Act).
