Abstract
EPA is finalizing a limited approval of revisions to the Indiana State Implementation Plan (SIP) submitted by the Indiana Department of Environmental Management (IDEM) on January 14, 2011, and March 10, 2011, addressing regional haze for the first implementation period that ends 2018. This action is being taken in accordance with the requirements of the Clean Air Act (CAA) and EPA's rules for states to prevent and remedy future and existing anthropogenic impairment of visibility in mandatory Class I areas through a regional haze program. As part of this action, EPA is also approving limits for the Alcoa facility that EPA finds satisfy the requirements for best available retrofit technology (BART).
