Mar 9, 2021 A Montana man pleaded guilty in federal court in the District of North Dakota to a felony charge of obstructing an Occupational Safety and Health Administration (OSHA) proceeding stemming from the 2014 death of an oil field worker in Williston, according to information provided by the U.S. Department of Justice. Stephan Todd Reisinger, 50, of Kalispell, was a maintenance manager at Nabors Completion and Production Services Company (NCPS) at its Williston facility. He supervised approximately 40 employees, including 28-year old U.S. Marine Corps veteran Dustin Payne. On Oct. 3, 2014, Payne welded on an uncleaned tanker trailer that had previously carried “produced water,” a liquid waste that is generated by oil wells and which contains flammable chemicals. The tank exploded and Payne was fatally injured.
