"U.S. Steel violated the Clean Air Act numerous times — in one case, more than 15,000 times — at its Gary Works facility and two other plants in Michigan and Illinois, according to a lawsuit filed by the federal government Wednesday in the U.S. District Court in Hammond."

"The suit said that from 2008 through 2011, three violation notices have been sent to the Gary Works plant, two to the Great Lakes Works facility in Ecorse, Mich., and one to the Granite City Works facility in Granite City, Ill.

Jill E. Ritchie, director of public policy and governmental affairs for U.S. Steel, said in a statement that the claims made in the lawsuit are 'inaccurate and misleading.'"
