Updated Information on Crow Butte Resources North Trend Expansion


Information updated – Aug. 17, 2011

The Nebraska Department of Environmental Quality has approved a Class III Underground Injection Control Permit submitted by Crow Butte Resources Inc. This permit is associated with an expansion area for the Crow Butte uranium mining facility, in an area north of Crawford that is referred to as the North Trend Expansion Area (see map below).


The North Trend Expansion Area permit includes approximately 1,165 acres, and the production zone associated with the proposed Class III permit ranges from an approximate depth of 350 feet below ground surface at the northern and southern permit boundary to 700 feet below ground surface in the center of the permit boundary. Mining will consist of injection of a sodium carbonate/bicarbonate solution along with an oxidant to the uranium-bearing formation through a pattern of injection wells. The solution will be pumped from the recovery wells to the satellite plant where the uranium will be extracted.

NDEQ developed a Responsiveness Summary to comments received, which has been mailed to commenters and is also provided below in “Related Documents.” Other documents provided below include: the final Class III permit; a Fact Sheet relating to the permit; and the Aquifer Exemption Order and related documents.
