Re: Response to Preliminary Adequacy Review, File No. M-2007-044
Whirlwind Mine, Mesa County, Colorado
Dear Russ:
Energy Fuels Resources Corporation's (Energy Fuel's) response to the Division of
Reclamation, Mining and Safety's (DRMS's) Preliminary Adequacy Review (PAR) is
presented below. If these responses adequately address your concerns, we will incorporate
the proposed changes and additional information into the 112d application and the BLM
Plan of Operations. If one or more of our responses do not fully address your concerns, we
would like to arrange afollow-up conference call or meeting to discuss any remaining
concerns in more detail. DRMS's comments are shown in italics below with Energy Fuels
responses in regular font.
1) Please provide written permission for the Division to release all information regarding
the review and installation of the water treatment plant approved under the Whirlwind
Notice oflntent.
An as-built report that contains pertinent design, installation, and regulatory
information for the treatment system was submitted to DRMS on November 17, 2007.
This information is not confidential and can be released to the general public.
2) Pg D-32 and Appendix H. Treatment process for removal of uranium, radium,
arsenic, and selenium is described. SPLP indicates other regulated constituents have
been detected in leachate, including Cd, Pb, V, Zn, although not at the elevated
concentrations of those proposed for treatment. Additionally, underground blasting
could introduce elevated concentrations of nitrate/nitrite/ammonia in mine water. In
the event that these constituents appear in mine water at concentrations greater than
anticipated, are provisions being made in the water treatment process to address
these contingencies?
