The Environmental Protection Agency (EPA) is proposing to approve revisions to the Arizona State Implementation Plan (SIP). These revisions concern emissions of lead and sulfur dioxide (SO2) from the copper smelter at Hayden, AZ and SO2 from the copper smelter at Miami, AZ. We are proposing to approve State rules to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
