GRASSY BUTTE, N.D. - An equipment failure caused about 340 barrels, or 14,280 gallons, of saltwater to spill at a site in Billings County, the Department of Mineral Resources said Wednesday.
Cobra Oil and Gas Corp. reported the release occurred 5 a.m. Tuesday at a central tank battery about 14 miles southwest of Grassy Butte. The spill was contained and recovered at the location. The cause was attributed to a transfer pump that failed.
A state inspector has been to the site.
