"EPA Objects To Air Quality Permit Issued To US Steel’s Clairton Coke Works"
"The Environmental Protection Agency objected to an air quality permit issued to U.S. Steel's Clairton Coke Works, a move advocates say will protect Mon Valley residents from emissions of harmful air pollutants. The EPA filed the objection under the grounds that the permit — which was issued by the Allegheny County Health Department in November — did not comply with the Clean Air Act."
