2.0 Site Status Summary

The Homestake Mining Company of California (Homestake), Grants Reclamation Project, near Milan, NM, is a conventional uranium mill site under reclamation. Uranium processing started in the late 1950's and continued until 1990. Tailings generated from the milling operation were placed on two piles, a large tailings pile and a small tailing pile. The facility has a tailings area of 270 acres with a weight of approximately 22 million tons. Seepage from the tailings piles was noted in 1975. The current effort is a major groundwater corrective action plan which is also under the oversight of the EPA through Superfund.  A Memorandum of Understanding has been executed between NRC and EPA for this site regarding groundwater remediation.

Groundwater restoration activities are being conducted in accordance with the NRC License SUA-1471. In 2006, Homestake submitted an updated groundwater Corrective Action Plan (CAP). Based on a NRC request for additional information, Homestake submitted Revision 2 of the CAP in March 2012 for the NRC review and approval. The site was subject to an NRC Confirmatory Order in on March 28, 2017, that placed sixteen additional requirements into the Homestake license to be completed by the licensee. Homestake has completed some of the requirements, is in the processes of completing some requirements, and some requirements have been submitted to the NRC and are under review.

A third revision to the CAP is expected to be submitted in December 2019.
