The Environmental Protection Agency (EPA) is proposing to take the following four actions regarding the Alabama State Implementation Plan (SIP), contingent upon a final determination from the Agency that a state's participation in the Cross-State Air Pollution Rule (CSAPR) continues to meet the Regional Haze Rule (RHR)'s criteria to qualify as an alternative to the application of Best Available Retrofit Technology (BART): Approve the portion of Alabama's October 26, 2015, SIP submittal seeking to change reliance from the Clean Air Interstate Rule (CAIR) to CSAPR for certain regional haze requirements; convert EPA's limited approval/limited disapproval of Alabama's July 15, 2008, regional haze SIP to a full approval; approve the visibility prong of Alabama's infrastructure SIP submittals for the 2012 Fine Particulate Matter (PM<INF>2.5</INF>), 2010 Nitrogen Dioxide (NO<INF>2</INF>), and 2010 Sulfur Dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS); and convert EPA's disapproval of the visibility portion of Alabama's infrastructure SIP submittal for the 2008 Ozone NAAQS to an approval.
