The City of Chicago is taking legal action against U.S. Steel after the company dumped more toxic metal into Lake Michigan last month.
In late October, nearly 60 pounds of chromium leaked into a Lake Michigan tributary after a wastewater treatment system malfunctioned at the U.S. Steel factory in northwest Indiana. It was the second time it’s happened in the past six months.
Mayor Rahm Emanuel says U.S. Steel tried to keep the spill a secret, requesting “confidential treatment” while reporting it to the Indiana Department of Environmental Management, and never notifying the EPA. Emanuel says the company has repeatedly violated the Clean Water Act, and the City will take the first step towards filing a lawsuit against it Monday morning.
