Re: Nahcolite Project, Permit No. M-1983-194, Technical Revision Approval, Revision No. TR-25
Dear Mr. Gunn:
On May 21, 2008 the Division of Reclamation, Mining and Safety approved the Technical Revision application
submitted to the Division on April 21, 2008, addressing the following:
Add production well 7H-1 V
The terms of the Technical Revision No. 25 approved by the Division are hereby incorporated into Permit No. M-1983-
194. All other conditions and requirements of Permit No. M-1983-194 remain in full force and effect.
Per my May 21, 2008 phone conversation with Cindi Byrns, the DRMS reclamation cost estimate of $27,500 for this pad
and well is acceptable to Natural Soda. This amount is calculated to be conservative as TR-25 did not contain specifics
for reclamation of this pad and well. Our calculation accounts for cut and fill operations for the pad, ripping of the
surface prior to replacement of 6 inches of topsoil, revegetation seeding with a diverse mix and application of fertilizer
and mulch. Hole abandonment is calculated for pulling the strings and filling the well full length with a type 11 cement..
In the future, please be aware that all revisions to the permit that include disturbance of additional surface and/or
installation of structures or features that will require reclamation, must include a detailed reclamation plan and cost
estimate.
The estimated liability amount of $178,250.00 exceeds the $150,750.00 performance bond currently held. If you have
not already done so, please submit additional bond in the amount of $27,500.00. The revision will not be final until the
bond is approved by the Division.
If you have any questions, please contact me.
Sincerely,
Steve S. Shuey
Environmental Protection Specialist
