The North Dakota Department of Environmental Quality (NDDEQ) has been notified of a produced water and oil spill resulting from multiple tanks overflowing at a salt water disposal (SWD) facility in Dunn County. The SWD is operated by Hunt Oil Company.


The incident occurred about 8 miles northwest of Halliday on January 5, and it was reported the next day. The cause of the spill was equipment failure due to a power outage triggered by high winds. 


Initial estimates indicate approximately 660 barrels of produced water and 370 barrels 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 NDDEQ are inspecting the site and will continue to monitor the investigation and remediation.
