EPA is proposing to approve a State implementation plan (SIP) revision submitted by the State of Colorado on May 25, 2011 that addresses regional haze (RH). EPA is proposing to determine that the plan submitted by Colorado satisfies the requirements of the Clean Air Act (CAA or "the 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.
