Approval and Promulgation of Air Quality Implementation Plan; Alabama; Disapproval of 110(a)(2)(E)(ii) Infrastructure Requirement for the 1997 Annual and 2006 24-Hour PM2.5

EPA is proposing to disapprove a portion of the State Implementation Plan (SIP) submissions, submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), on July 25, 2008, and on September 23, 2009, to demonstrate that the State meets requirements of sections 110(a)(1) and (2) of the Clean Air Act (CAA or Act) for the 1997 annual and 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure'' SIP. Specifically, EPA is proposing to disapprove sub-element 110(a)(2)(E)(ii) that requires the State to comply with section 128 of the CAA. EPA is taking a separate action to address all the other infrastructure elements for the 1997 annual and 2006 24-hour PM2.5 NAAQS.
