Dennis A. Henman of Ft. Wayne, Ind. pled guilty on March 26 to violating the Clean Water Act by discharging oily wastewater into the municipal sewers of Dayton, Ohio.
Henman was a district manager for Grease Monkey, Inc. an automobile oil change franchise. The defendant did not have a permit from the city of Dayton to discharge the oily wastewater into the sewer system.
Unpermitted discharge of oily water into city sewers can create a fire hazard and can prevent the proper treatment of sewage. This creates a hazard to fish and wildlife that depend upon surface waters that are downstream of sewage treatment plant outfalls.
The case was investigated by the Cleveland Area Office of EPA's Criminal Investigation Division, the Ohio Environmental Protection Agency, the Ohio Bureau of Criminal Identification and Investigation, the Wastewater Division of the City of Dayton and the Montgomery County Sanitary Engineering Department.
It is being prosecuted by the U.S. Attorney's Office in Dayton.
