Re: White River City Pit, II2c Application No. M-200ti-084, Initia(Reclamation Liability Estimate.
Dear Mr. Wenzel:
The Division of Reclamation, Mining and Safety has finished the review of the above referenced 112c application. I[ appears
that all issues have been addressed to meet the minimum requirements of the Act and Rules. The final issue prior to a
decision is the agreement on the Initial Reclamation Liability.
Please find attached staff's estimate for the costs for initial reclamation. There is a substantial difference between the final
sum submitted in Exhibit L and staff s. Several factors add up to the discrepancy.
]) The pit will have to be pumped almost dry not half way as estimated in Exhibit L. To establish 3:1 slopes on the
west end the material must be compacted from the toe of the slope~up prior to any significant water saturation.
2) The Reclamation Plan states 15 to 18" of topsoil are to be replaced. Exhibit L notes only 8. Staff must go by what
the plan notes and with the most conservative of the estimate range.
3) Given the amount of topsoil to be replaced and distance to move it, scrapers will need to be utilized, not a dozer.
Given the fact that the equipment will be on site for overburden movement [o slopes there is no additional costs for
mobilization, etc.
4) Staff must assume that the entire processing area will be utilized and therefore must be top soiled and revegetated.
This adds to the total area of disturbance in the worst case scenario noted in Exhibit L.
Other costs differentials appear to be more due to inflationary costs, etc. but added up. Please review the estimate and feel
free to contact staff if there are issues or errors. As a reminder, the Decision Date is May 17`", 2007. If the estimate is
acceptable, please call staff as soon as possible so the Decision Date can be met. If there are issues with the bond it is most
likely that the applicant will need to request an extension of the decision date for 7 days so [his final issue can be resolved.
If you need additional information, please contact me at the Division of Reclamation, Mining and Safety, Grand Junction
Field Office, 101 S. 3rd St., Suite 301, Grand Junction, Colorado 81501, telephone no. 970.241.1117.
