COLUMBUS - The Ohio Supreme Court has dismissed an environmental group's case seeking documents related to alleged illegal dumping of wastewater from oil and gas drilling into the Mahoning River along the border of Trumbull and Mahoning counties.
Justices ended the Sierra Club's case against the Ohio Department of Natural Resources on Tuesday in the wake of a settlement agreement.
The court indicates the group has resolved its allegation that the state failed to produce public records it requested six months earlier.
The club's Ohio chapter sought documents related to the department's investigation of D&L Energy and Hardrock Excavating in Youngstown.
The department revoked the firms' permits in February amid a federal investigation into the dumping of up to 40,000 gallons of wastewater from hydraulic fracturing into a storm sewer that drains into the Mahoning.
