Sulfur Dioxide (SO2) Updates for Hayden and Miami Planning Areas (18 Arizona Administrative Code 2, Article 2)

ADEQ is considering amendments to R18-2-715 and R18-2- 715.01 in order to establish new emissions limitations for Existing Primary Copper Smelters within designated nonattainment areas for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS). On June 22, 2010, EPA revised the one-hour average and annual average NAAQS for SO2. 75 FR 35520. On Aug.5, 2013, the Environmental Protection Agency published new designations for the NAAQS for the Hayden and Miami nonattainment areas, effective Oct. 4, 2013. 78 FR 47191. The rules will become part of the State Implementation Plans (SIPs) for both areas.
