Washington, DC - John Tuma, 55, of Centerville, Texas, was sentenced today following his March 21, 2012, trial conviction by a federal jury for discharging untreated wastewater directly into the Red River without a permit, discharging untreated wastewater into the city of Shreveport sewer system in violation of its permit and obstructing an EPA inspection,

announced Ignacia S. Moreno, Assistant Attorney General of the Justice Department’s Environment and Natural Resources Division and U.S. Attorney Stephanie A. Finley of the Western District of Louisiana. U.S. District Judge Tom Stagg sentenced John Tuma to a 60-month prison sentence, three years of supervised release and a $100,000 fine.

John Tuma, who was both general manager and the former owner of Arkla Disposal Services Inc., was charged in a five-count indictment with violations of the Clean Water Act, conspiracy and obstruction of justice related to illegal discharges coming from the Arkla Disposal Services Inc., a facility in Shreveport. The Arkla facility, located at 10845 Highway 1 South in Shreveport, was a centralized wastewater treatment facility that received wastewater from industrial processes and oilfield exploration and production facilities. Arkla contracted to treat the wastewater through a multi-step treatment process and then discharge the treated wastewater to either the City of Shreveport publicly owned treatment works or the Red River.

The case was investigated by EPA’s Criminal Investigation Division and is being prosecuted by Assistant U.S. Attorney C. Mignonne Griffing and Trial Attorney Leslie E. Lehnert of the Environmental Crimes Section of the Department of Justice.
