The U.S. Environmental Protection Agency is proposing expensive pollution controls at six facilities in Arizona. The sites include Tucson Electric Power’s Sundt Plant in Tucson, Chemical Lime Nelson in Peach Springs, ASARCO’s Hayden Smelter, Freeport McMoran’s Miami Smelter, Phoenix Cement Company’s Clarkdale plant and CalPortland Cement Company’s Rillito plant.
EPA will hold public hearings on February 25, 2014, in Phoenix and on February 26, 2014, in Tucson and will accept comments for 45 days after publication in the Federal Register. A final determination will be made by June 27, 2014.
