Surfrider Chicago is looking to relaunch its federal lawsuit against U.S. Steel, which it says sickened surfers when it dumped toxic hexavalent chromium in a waterway connected to Lake Michigan in northwest Indiana.



  U.S. Steel did not respond to a request for comment.



                     Mitch McNeil, chairman of Surfrider Chicago, said that he hopes that a revised settlement between U.S. Steel and the EPA will “serve as a statement that this is serious and [that] we’re watching.”
