Reply to Advisory Regarding Potential Impact of Proposed Water
Supply Well and Pipeline Project in the Vicinity of the Southern LTSM
Boundary.
Dear Mr. Rnerfrock,
Ttiis letter is in reply to your letter addressed to Billy Ray, Project Engineer,
dated February 16, 2010, in which you advised of tv^o options for Rio
Algom Mining LLC in relation to the Bureau of Land Management's
possible approval of the installation of v/ater supply well(s) south of the
LTSM boundary. You advised that "additional modeling simulations
and/or construction of monitoring wells along the southern border of the
LTSM may be required in the future, depending on the final well location
selected."
In addition, Mr. Tom Rushing, PG, with the Division of Radiation Control,
sent an e-mail also doted February 16, 2010, that presented another
option for Rio Algom Mining to consider. This option was to utilize two
existing monitor wells as compliance wells, and would require
development of compliance limits for background well MW-13 and trend
well H-63. A copy of Mr. Rushing's email has been attached with this
letter.
Rio Algom Mining appreciates being kept apprised of activity in the area
and fully intends to continue to satisfy and fully cooperate regarding all of
its obligations. Please be aware, however, that Rio Algom Mining does

not believe it is responsible for any additional modeling simulations and/or
construction of monitoring wells, or any additional monitoring related to
the possible installation of new water supply wells south of the LTSM
boundary as described by you and Mr. Rushing.
Please do not hesitate to contact me If you would like to discuss this
further.
Sincerely,
