CLEVELAND, Ohio (WKBN) — Mark Goff pleaded guilty Monday in Cleveland in connection with dumping drilling waste from a Youngstown-area business into the Mahoning River.
Goff’s plea marks the third guilty entry in a case involving Hardrock Excavating, LLC. Goff was in federal court Monday facing one count of making an unpermitted discharge and violating the Clean Water Act.
Goff claims he was told to empty the waste into the river by his former boss, Hardrock Excavating owner Ben Lupo.
Lupo and Michael Guesman have already pleaded guilty in the case. Guesman got three years probation, and Lupo will be sentenced in June.
