Abstract
EPA is finalizing a full approval of some revisions to the Arizona Department of Environmental Quality (ADEQ) portion of the Arizona State Implementation Plan (SIP) and a limited approval/limited disapproval of another revision to the SIP. This action was proposed in the Federal Register on May 14, 2004 and concerns sulfur dioxide (SO<INF>2</INF>) emissions from existing primary copper smelters. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), this action simultaneously approves rules that regulate these emission sources and directs Arizona to correct rule deficiencies.
