BISMARCK – The North Dakota Department of Health (NDDoH) has been notified of an oil and brine spill resulting from a treater leak in Mountrail County at a site operated by Arsenal Energy USA, Inc. The spill occurred on Monday, Oct. 17, approximately 3.5 miles southeast of Stanley.
A treater is a vessel used to separate and condition oil-gas-salt water emulsions so the oil may be accepted for transport.
Initial estimates indicate approximately 40 barrels of oil and 30 barrels of brine were released. Of this, an undetermined amount of oil and brine flowed into a stock pond located 180 feet north of the site.
The cleanup is under way. Personnel from the North Dakota Oil and Gas Division and the NDDoH are at the site. NDDoH personnel will continue to monitor the investigation and the remediation process.
