Abstract
EPA is taking direct final action to approve revisions to the Arizona Department of Environmental Quality (ADEQ) portion of the Arizona State Implementation Plan (SIP). These revisions concern procedures for the calculation of sulfur emissions from copper smelters. We are approving a local rule that helps regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
