Approval and Promulgation of Implementation Plans; Tennessee; Regional Haze State Implementation Plan; Best Available Retrofit Technology for Eastman Chemical Company

EPA is proposing to approve a revision to the State Implementation Plan (SIP) submitted by the State of Tennessee, through the Tennessee Department Environment and Conservation (TDEC), on May 14, 2012, related to the Best Available Retrofit Technology (BART) requirements for the Eastman Chemical Company (Eastman). Specifically, the May 14, 2012, SIP revision modifies the compliance date for the Eastman BART determination included in Tennessee's April 4, 2008, SIP revision and provides a BART alternative determination option for Eastman. Together, Tennessee's April 4, 2008, and May 14, 2012, SIP revisions address the requirements of the Clean Air Act (CAA or Act) and EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas (national parks and wilderness areas) caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). EPA is proposing to approve Tennessee's May 14, 2012, SIP revision because it is consistent with the CAA and EPA's regulations on regional haze BART determinations and BART alternative determinations.
