BISMARCK, N.D. — The North Dakota Health Department says mechanical failures are to blame for two separate spills in the state's oil patch.
Water Quality Director Karl Rockeman says about 2,000 gallons of oily water leaked from a flow line on Monday near Marmarth, in southwest North Dakota. Rockeman says the line is owned by Denbury Onshore. He says most of the oil water soaked into the soil and a dike was constructed to control runoff.
The second spill was reported last week near Ray, in northwest North Dakota.
Rockeman says about 20 barrels of oil and water escaped from a broken valve at well owned by Kodiak Oil and Gas. He says oily mixture flowed about 150 feet into a dry stream bed before being recovered.
