Company: Equipment didn’t detect North Dakota oil leak
BISMARCK, N.D. — Electronic monitoring equipment failed to detect a pipeline rupture that spewed more than 176,000 gallons of crude oil into a North Dakota creek, the pipeline’s operator said Monday.
It’s not yet clear why the monitoring equipment didn’t detect the leak, Wendy Owen, a spokeswoman for Casper, Wyoming-based True Cos., which operates the Belle Fourche Pipeline, said.
A landowner discovered the spill near Belfield on Dec. 5, according to Bill Suess, an environmental scientist with the North Dakota Health Department.
