RE: Bowie No. 2 Mine, Permit No. C-96-083, Bowie Resources LLC
Technical Revision No. 57, Mine Water Discharge into Somerset Mine, Adequacy
Review Letter
Dear Mr. Bear:
The Colorado Division of Reclamation, Mining and Safety (Division) has finished its review of
Technical Revision No. 57 (TR-57) for the Bowie No. 2 Mine. TR-57, dated October 28, 2008, was
submitted by Bowie Resources LLC (BRL). The following are the Division's questions and
comments:
1. BRL has adequately described the location of the borehole and wellhead configuration in the
approval request letter to MSHA which would be incorporated into the PAP as Volume IIIA
Tab 14, upon approval of TR-57. The precise location for the borehole is described in the
MSHA letter but not in the amended permit pages. Please add a brief discussion to the bottom
of page 2.05-73 describing the sump, borehole and discharge location and add these locations to
a map prepared in accordance with the standards of Rule 2.10.
2. In Item 1 on page 2.05-74 BRL states that the North Fork of the Gunnison River will eventually
receive water that is discharged into the old U.S. Steel Mine and the flow from the mine will
primarily enter the river through outcrop seepage. Rule 4.05.16 (3) requires that in the case of
underground mining activities, the discharge continue as a controlled and identifiable flow and
ultimately be treated by an existing treatment facility. Since flow from the mine will enter the
river through outcrop seepage, BRL should provide an update to the PHC with an estimated
volume and rate of discharge through the outcrop and describe any potential impacts to the
hydrologic balance as a result of the mine water seepage. Please update the PHC with the
formation/outcrop that the water is expected to discharge through, the estimated seepage
velocity and volume of discharge, and provide an approximate location and elevation relative to
the North Fork of the Gunnison River that discharge is expected to occur. The map should be
prepared in accordance with Rule 2.10.
3. Rule 4.05.16(2) requires that the discharge be a controlled and identifiable flow, meeting the
requirements of 4.05.2 for pH and total suspended solids. Initially the flow is controlled and
