ArcelorMittal, Cliffs appealing EPA ruling

Keywords: Tags  ArcelorMittal USA, Cliffs Natural Resources, Inc., taconite ruling, U.S. Environmental Protection Agency, emissions, appeal, Samuel Frizelll

NEW YORK — ArcelorMittal USA LLC and Cliffs Natural Resources Inc. have filed separate but almost identical petitions in an appellate court challenging the U.S. Environmental Protection Agency’s new regulations for taconite ore processing facilities in Minnesota and Michigan.

EPA regulations on nitrous oxide and sulfur dioxide emissions for taconite miners and processors in Michigan and Minnesota went into effect March 8 much to the chagrin of ArcelorMittal and Cliffs, which—along with the National Mining Association—have publicly opposed the regulations since they were proposed in July (, April 3). According to the miners, the federal regulations violate states’ rights and could cost them millions of dollars in retrofit expenditures and lost production.

The petitions seeking judicial review were both filed April 4 in the U.S. Court of Appeals for the Eight Circuit, documents show.
