Cliffs Burns Harbor (Cleveland-Cliffs) has agreed to resolve alleged violations of the Clean Water Act (CWA) and other laws, for an August 2019 discharge of ammonia and cyanide-laden wastewater into the East Branch of the Little Calumet River. The discharge, which led to fish kills in the river, also caused beach closures along the Indiana Dunes National Lakeshore.
