RE: Bowie No. 2 Mine, Permit No. C-96-083, Bowie Resources LLC
Technical Revision No. 52, Thirteen Gob Vent Boreholes, Second Adequacy Review
Dear Mr. Bear:
The Colorado Division of Reclamation, Mining and Safety (Division) has finished its adequacy review of
Bowie Resources LLC's (BRL) responses dated March 3, 2008 for Technical Revision No. 52 (TR-52) for the
Bowie No. 2 Mine. The following is the status of the Division's questions and comments:
Section 2.03.6, Right of Entry and Operation Information
Please provide documentation that the USDA-Forest Service and the Bureau of Land Management
approve of this project. The Division understands that the NEPA process will be utilized for TR-52.
In the submittal dated March 3, 2008, BRL committed to providing the USDA-FS and BLM
approvals.
Section 2.05.4, Reclamation Plan
2. In the cover letter for the TR-52 submittal, BRL requested incremental bonding. The Division was
agreeable with incremental bondingprovided a certain methodology was used. In the submittal dated
March 3, 2008, BRL decided not to use incremental bonding. Therefore, the Division calculated the
total reclamation bond for TR-52.
Attached is the Division's reclamation cost estimate for TR-52. The estimate consists of a summary
sheet and tasks nos. 271 through 278, for a total of nine tasks, and represents an increase in liability of
$273,624.00.
The Division's estimate is approximately $75,000 more than the estimate submitted by BRL. The
main reason for the higher Division estimate is the earthwork costs (dozer tasks nos. 272-275). BRL
estimates the earthwork costs at approximately $14,000, while the Division estimates the earthwork
costs at approximately $93,000. In BRL's estimate, a generalized cost of $90/hour for the equipment
and a generalized time of4 hours/pad for reclamation is used. The Division estimates the quantity of
dirt moved and the variables (adjustment factors) that go into the tasks. Additionally, there does not
appear to be a cost for topsoil replacement in the BRL estimate, which accounts for approximately
$28,000 of the earthwork costs.
