ROSS, N.D. (AP) -- State officials say a spill of 427 barrels of oil and 142 barrels of saltwater was contained and recovered at a well site in Mountrail County.
A state inspector visited the Statoil Oil & Gas site about 7 miles south of Ross. A valve failure was determined to have caused the spill that was reported Tuesday.
A barrel holds 42 gallons. Saltwater is a byproduct of oil production.
