Abstract
EPA is finalizing a partial disapproval of the Arizona State Implementation Plan (SIP) to implement the regional haze program for the first planning period through 2018. Regional haze is caused by emissions of air pollutants from numerous sources located over a broad geographic area. The Clean Air Act ("CAA" or the "Act") and EPA's regulations require states to adopt and submit to EPA SIPs that assure reasonable progress toward the national goal of achieving natural visibility conditions in 156 national parks and wilderness areas designated as Class I areas.
