RE: Radioactive Material License (RML) Number UT 1900479: Additional Request for
Information on Proposed Altemate Feed Amendment Request -Material from Dawn Mining
Company :
Dear Mr. Roberts:'
The Division of Radiation Control (DRC) received an additional item regarding URS's review of
the Dawn Mining altemate feed material amendment request. The following specific comment is in
addition to the comments provided to Energy Fuels Resources in letter dated January 22, 2013. 'The
DRC apologizes for not including this in the previous letter. Please add the following additional
comment under "Specific Comments":
Item 18. (New) Tab (Attachment) 5, Table 6: Please verify the accuracy/correctness of calculations
and/or explain as appropriate (in a revised updated version of Section 8.0 of Attachment 5) the
significance of computational results listed for certain constituents in Table 6 of Attachment 5 to the
April 27, 2011 Amendment Request. The projected percentages of the total mass in the tailings
disposal cells after completion of processing of the Uranium Material (processing of shipments of
the DMC Uranium Material periodically received over a 10-year period) contributed by some
constituent inventories (e.g., barium, copper, manganese, silver, beryllium, calcium, etc..) appear
to be relatively high.
Please feel free to contact me at 801-536-4263, if you have any concerns or questions regarding this
letter.
Sincerely
/Ir; I
