Firstly, the U.S. Environmental Protection Agency (USEPA) is proposing pollution controls at six facilities in Arizona to improve visibility at national parks and wilderness areas.
EPA is proposing a federal plan to limit emissions such as nitrogen oxides and sulfur dioxide tailored to six facilities. First off, Tucson Electric Power’s Sundt Plant in Tucson. Then the Chemical Lime Nelson in Peach Springs and ASARCO’s Hayden Smelter. In addition is Freeport McMoran’s Miami Smelter and the Phoenix Cement Company’s Clarkdale plant. Finally and in also the CalPortland Cement Company’s Rillito plant. As a part of this process, EPA also evaluated other sources but is not proposing to require any additional controls on these other sources at this time.
Most noteworthy, EPA estimates the proposal would reduce sulfur dioxide by almost 30,000 tons per year. As well, it will cut nitrogen oxides by around 3,100 tons per year.
EPA public hearings on February 25, 2014. Finally, in Phoenix and on February 26, 2014. As well, in Tucson. In conclusion and will accept comments for 45 days after publication in the Federal Register. A final determination will be made by June 27, 2014.
