Louisiana: Man wants new trial in pollution case

SHREVEPORT, La. (AP) -- A Shreveport businessman has asked for a new trial after being convicted of several violations including the dumping of untreated wastewater directly into the Red River.

John Tuma, former president of ARKLA Disposal Services Inc., was convicted in March of dumping wastewater without a permit, discharging untreated wastewater into Shreveport's sewer system and obstructing an Environmental Protection Agency inspection.

Tuma's lawyer said he didn't get a fair trial.

In February of 2011, Tuma, of Centerville, Texas, and his son Cody Tuma of Shreveport, were both charged in a five-count indictment. Cody Tuma pleaded guilty in February of 2012 to one count of negligently discharging pollutants into the Red River without a permit.

Arkla Disposal Inc. operated as a treatment facility for wastewater related to oil and gas exploration and production.
