Arizona copper
smelting plant cited for air violations
Sept. 30 -- Asarco Inc. allegedly violated the Clean Air Act at its
Hayden, Ariz., copper smelter, according to a U.S. Environmental
Protection Agency complaint.
The facility allegedly emitted more than its allowable 20 percent of
opacity emissions from September 2002 through December 2002, and it
failed to properly operate pollution control equipment at the facility
to minimize emissions, the agency said.
The EPA measures opacity by determining the percentage of light that
passes through emissions. |
