(AP) — The North Dakota Oil and Gas Division says most of a contained release has been recovered at a saltwater disposal well in McKenzie County.
McKenzie Energy Partners reported 6,300 gallons of oil and 6,300 gallons of saltwater were released and contained within site diking about 13 miles northeast of Alexander. All but 84 gallons of saltwater was recovered.
Authorities say a power failure caused the tank to overflow.
The Oil and Gas Division was notified Monday of the release. A state inspector has been to the location.
