SIOUX FALLS, S.D. (AP) - A North Dakota health official says oil from a well near the confluence of the Yellowstone and Missouri rivers spilled into floodwaters but has been contained.
Kris Roberts with the North Dakota Department of Health says no more than 33 barrels were spilled on Friday in the area southwest of Williston and east of the North Dakota-Montana border.
The well is operated by Colorado-based Zavanna, LLC. The company did not immediately return calls seeking comment.
Roberts says the well was surrounded by dikes, but some of the oil escaped from a breach in one dike and got into the floodwaters.
Roberts says Zavanna workers have contained all the oil after placing a containment boom.
Ice jams have caused the waters to rise and flood the wells.
