BISMARCK, N.D. (AP) - The North Dakota Department of Health says it is monitoring an emulsion spill in Billings County.
The health department says the spill happened Saturday after a flow line leak at a site operated by White Rock Oil and Gas, about 16 miles northwest of Belfield.
Emulsion is a mixture of oil and salt water that comes out of the well prior to treatment. Initial estimates show about 280 barrels of salt water and 20 barrels of oil were released.
Oil and salt water flowed into a drainage area that leads to Franks Creek. The health department says the crude oil appears to be confined to a drainage area, but an unknown amount of salt water flowed through the drainage and into the creek.
