Abstract
The Environmental Protection Agency (EPA) is taking final action on a portion of a January 31, 2013 submission and a December 22, 2015 supplemental submission from the State of Utah that are intended to demonstrate that the Utah State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2008 ozone National Ambient Air Quality Standards (NAAQS). The interstate transport requirements under the CAA consist of four elements: Significant contribution to nonattainment (prong 1) and interference with maintenance (prong 2) of the NAAQS in other states; and interference with measures required to be included in the plan for other states to prevent significant deterioration of air quality (prong 3) or to protect visibility (prong 4). Specifically, the EPA is approving interstate transport prong 1 for the 2008 ozone NAAQS.
