CLEVELAND: An Ohio man has changed his plea to guilty to a charge alleging he violated the Clean Water Act by repeatedly discharging gas-drilling wastewater into a storm sewer.
The U.S. Attorney in Cleveland Steven Dettelbach on Thursday announced that 34-year-old Michael P. Guesman admitted to illegally dumping brine and oil-based drilling mud into a sewer that empties into the Mahoning River watershed.
The Cortland man had pleaded not guilty in March to the charge in the federal indictment against him, a northeast Ohio business and its owner. Authorities allege the owner of Hardrock Excavating LLC, Ben Lupo, directed Guesman to illegally dump the wastewater.
Guesmanís attorney didnít immediately return a request for comment.
The state revoked Hardrockís permits after some workers reported seeing the material being dumped.
