A frozen pipe caused a saltwater spill of more than 10,000 gallons about five miles north of Fortuna, ND, state officials said.
The North Dakota Oil and Gas Division said American Eagle Energy Corp. reported the 250-barrel release on Tuesday.
All the saltwater ended up contained and recovered on the site, the officials said.
A state inspector will continue to investigate the incident.
While the cold Arctic blast of weather hit the region, North Dakota is still experiencing spills of oil or brine across the state.
Just last week, an oil well blowout released over 25,000 gallons of crude oil at a site in McKenzie County, ND, and state health officials said they were still evaluating whether any of it reached a tributary of the Missouri River.
Petro-Hunt LLC reported that 600 barrels of crude released from the well and wasn’t contained on the site roughly one mile northwest of Keene, said Department of Health officials.
Also, over 1,600 barrels of crude caught fire just south of Williston in late December after 8 of 12 storage tanks ignited while trucks were delivering oil, officials said.
The tanks were just across the street from a major Enbridge Inc crude oil facility. That facility did not appear to have suffered damage, officials said. In addition, there were no injuries in the incident.
