BISMARCK, N.D. – An oil and saltwater spill from an equipment failure on a well pad near Bowbells in far northern North Dakota has flowed into an adjacent slough.
The North Dakota Department of Health was notified Sunday, May 21, of the 100-barrel or 4,200-gallon oil emulsion spill at the site about 70 miles northwest of Minot.
The spill on Saturday, May 20, was at a well pad operated by Cornerstone Natural Resources LLC. Oil emulsion is a mixture of crude oil and saltwater produced from a well and before treatment.
The spill was an estimated 25 barrels or 1,050 gallons of oil and 75 barrels or 3,150 gallons of saltwater. An unknown amount of this emulsion flowed off the well pad and into the slough. Cornerstone has deployed booms in the slough to contain the emulsion, and an environmental remediation company has begun pumping impacted water out of the slough and excavating impacted soils.
NDDoH personnel have been on the site and will continue to monitor the investigation and cleanup.
From Jan. 1 to May 1, there have been 539 spills related to the oil and gas industry in North Dakota, according to the NDoH. That includes 287 oil spills, 176 saltwater spills and 76 in the other category.
