Federal officials want to enter into a revised consent agreement with a car ferry operator that would stop the nation's last coal-fired ferryboat from dumping waste ash into Lake Michigan before the 2015 sailing season.
The Environmental Protection Agency and the Justice Department filed a motion Friday to enter into the revised deal with Lake Michigan Carferry, operator of the S.S. Badger.
A federal judge has to approve the deal which also calls for a reduction in the amount of ash discharged this year and over the five-month 2014 sailing season.
The ferry company wants to install an onboard ash retention system.
The Badger hauls passengers, vehicles and cargo between its home port of Ludington and Manitowoc, Wis., from May to October.
