HALLIDAY — A produced water and oil spill caused by equipment failure due to a power outage triggered by high winds occurred at a saltwater disposal facility near Halliday on Sunday.

The incident in which multiple tanks overflowed occurred at the facility about 8 miles northwest of Halliday. It was reported the next day to the North Dakota Department of Environmental Quality.

The saltwater disposal facility is operated by Hunt Oil Company.

Initial estimates indicate approximately 660 barrels of produced water and 15,540 gallons of crude oil overflowed the tanks. Most of the released material was contained on site; however, the high winds resulted in some of the material being blown into adjacent pastureland.

Personnel from the state are inspecting the site and will continue to monitor the investigation and remediation.
