SIOUX FALLS, S.D. (AP) ¿ The Canadian developer of a planned uranium mine in southwest South Dakota can move ahead with its request for a federal permit, one of four needed to operate. The Nuclear Regulatory Commission informed Powertech Uranium Corp. that its application for a detailed technical and environmental review has been accepted for the Dewey Burdock project near Edgemont. The company is currently operating under a state permit to drill exploratory holes. It withdrew the federal application in June so it could fix several deficiencies that would have led to the proposal being rejected. NRC spokesman Scott Burnell said Tuesday that those issues have been addressed and the NRC staff has started reviewing the application. There will be an opportunity for a public hearing before the agency makes a decision on the project, which could happen within about two years, he said. The application accepted by the NRC is for a Source Material License, which deals with nearly every aspect of the proposal, said Mark Hollenbeck, Dewey Burdock project manager.
