Uranium mill tailings sites
Guidance for management of uranium mill tailings encountered during construction activities
Former uranium mill sites
Cleanup of former uranium mill sites in Colorado authorized by the Uranium Mill Tailings Remedial Action (UMTRA) program has been completed.
- This program facilitated the cleanup of 15 million cubic yards of uranium tailings at former uranium mill sites in nine western Colorado communities.
- Because much of the cleanup is complete, the focus has shifted to primarily "Post-UMTRA issues," or the discovery of new uranium mill tailings material by private citizens, utility companies or local governments.
