Abstract
EPA is partially approving and partially disapproving a State Implementation Plan (SIP) revision submitted by the State of Utah on May 26, 2011 that addresses regional haze. EPA is also approving specific sections of a State of Utah SIP revision submitted on September 9, 2008 to address regional haze. These SIP revisions were submitted to address the requirements of the Clean Air Act (CAA or Act) and our rules that require states to prevent any future and remedy any existing man-made impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the "regional haze program"). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is taking this action pursuant to section 110 of the CAA.
