2.0 Site Status Summary

The licensed site encompasses approximately 550 acres that includes Tailings Pile 2 consisting of approximately 80 acres and Tailings Pile 1 consisting of approximately 40 acres. Reclamation oversight of the facility has been transferred to the State of Wyoming, Department of Environmental Quality (WDEQ). This transfer occurred because ANC became insolvent in May 1994 and site reclamation was incomplete. A Confirmatory Order between NRC and the WDEQ describing the requirements for reclamation activities was agreed upon by both parties and was issued in October 1996. WDEQ performed an extensive review of the groundwater at the site and, as a result, the groundwater recovery and corrective action program was discontinued. Tailings Pile 2 reclamation activities were completed in February 1998. WDEQ's goal was to submit the final reclamation plan for Tailings Pile 1 for NRC review and approval in 2004 and complete the associated reclamation in 2005 but that has not been accomplished. Tailings Pile 1 activities are on hold and since the last inspection in May 2007, no site reclamation activities had been performed. After approval of the reclamation plan for Tailings Pile 1, activities will include the following: (1) windblown area clean-up activities, (2) capping with clay, (3) radon testing, and (4) placement of rip-rap rock. As of 2015 WDEQ does not have enough money to complete decommissioning. Several options have been proposed to obtain the necessary funds to complete the reclamation and the NRC and WDEQ staffs are evaluating the options. Eight new wells and 2 new surface water sampling stations were installed to better define the extent of the plume of contamination that is leaving the site.
