The U.S. Environmental Protection Agency (EPA) is proposing new pollution controls for six Arizona industrial facilities – including Phoenix Cement Co.’s Clarkdale plant and CalPortland Cement Co.’s Rillito plant – to improve visibility at national parks and wilderness areas. Emissions of sulfur dioxide and nitrogen oxides would be reduced by 30,000 tpy and 3,100 tpy, respectively, under the new proposal.

The EPA will hold public hearings February 25 in Phoenix and February 26 in Tucson.  Comments will be accepted for 45 days after publication in the Federal Register. A final decision will be made by June 27.
