Dear Ms. Tischler:
SUBJECT: January 10, 2011 DUSA Letter, Transmits Revised DMT and BAT O&M Plans, which
addresses White Mesa Uranium Mill Tailings Cell 4B, etc.; January 6, 2011 DRC Letter,
Review of Revised DMT and BAT O&M Plans;
Contingent Approval of the Proposed DMT Plan
We have reviewed the subject letter from DUSA dated January 10, 2011, which is a response to the subject
DRC comment letter of January 6, 2011. The DUS A letter proposes the two subject documents, noted
above. However, this letter only addresses the proposed DMT Plan, as revised, known as The White Mesa
Mill Tailings Management System and Discharge Minimization Teclinology (DMT) Monitoring Plan
(DMT Plan), 01/11 Revision: Denison-11.1.
After review of this plan, we have no further comments. Therefore, the DMT Plan as titled immediately
above, is approved, contingent upon DUSA receiving written DRC authorization to use Cell 4B.
