WILLISTON, N.D. (AP) - North Dakota oil regulators say a well in Mountrail County spilled 830 barrels of saltwater, but the mess was cleaned up.
The well about six miles southwest of Ross is owned by the Norwegian energy company Statoil.
The North Dakota Oil and Gas Division says a failed valve caused a tank to overflow Wednesday. Officials say the spill was contained on the well location and all of the spilled fluid was recovered. A barrel holds 42 gallons.
Saltwater is a byproduct of oil production. It is many times saltier than seawater and is treated as an environmental hazard by the state.
