Officials with the North Dakota Health Department reported an oil and brine spill at a site in Mountrail County and say the spill is currently being treated and monitored.
Officials approximate that 40 barrels of oil and 30 barrels of brine leaked Monday at a site operated by Arsenal Energy USA, a total nearing 3,000 gallons combined.
The release was most likely due to a treater leak, according to state officials.
A treater is a vessel used to treat oil-water emulsions and separate the oil so that it may be transported through a conduit.
The leak is currently under investigation.
