"Asarco Copper Mill to Double Output While Cutting Dust Emissions
Nov. 10--Asarco will nearly double production at a mill south of Tucson, but it says it will reduce dust emissions slightly by adding pollution controls in a $65 million upgrade.
The mining company wants the Pima County Department of Environmental Quality to revise its air quality permit so it can increase the amount of copper ore running through its Mission Mine's south mill by about 71 percent.... County regulators say they agree with Asarco's calculations that emissions will decline despite the higher production levels.
The mill, just south of Pima Mine Road and west of Interstate 19, is one of two at the Mission complex, which employs about 625 people.
After the mine expands the south mill's production capacity, total employment will rise by perhaps 10 to 15 people in about the first quarter of 2013, said Tom Aldrich, Asarco's vice president of environmental affairs."http://southwest.construction.com/yb/sw/article.aspx?story_id=165754240
