Mark A. Goff, the fourth defendant accused of violating the federal Clean Water Act by dumping oil-field waste into the Mahoning River tributary, was sentenced to three years probation and 300 hours community service by U.S. District Judge Donald C. Nugent — the same sentence another employee of Hardrock Excavating LLC received.
Goff, 46, of Newton Falls pleaded guilty to the violation in April.
He was charged in an information and, in doing so, waived his right to be indicted by a grand jury.
Goff was accused of emptying liquid waste from storage tanks into a storm water drain on Salt Springs Road in Youngstown on nine nights between Oct. 1 and Nov. 12, 2012 at the direction of his boss, Ben Lupo.
Lupo, 63, of Springfield, the company and another employee, Michael P. Guesman, 35, of Cortland were all charged with the offense.
Guesman pleaded guilty to dumping the waste at Lupo’s direction for 24 nights beginning Dec. 12, 2012. He received the same sentence as Goff from the same judge in March.
Lupo will be sentenced at 10 a.m. Aug. 5.
A Jan. 31, 2013, discharge of brine, drilling mud and drill cuttings triggered a massive multi-agency investigation of the case and a $3 million cleanup. The penalty range for violating the Clean Water Act is probation to three years in prison and a fine up to $250,000, according to The Vindicator files.
