RE: Bowie No. 2 Mine, Permit No. C-96-083, Bowie Resources LLC
Technical Revision No. 43, New Borrow Area and Revised Drainage Plan
Dear Mr. Bear:
The Colorado Division of Minerals and Geology (Division) has finished its adequacy review of Bowie
Resources LLC's (BRL) submittal, dated July 7, 2006, for TR-43 for the Bowie No. 2 Mine. The submittal
was in response to the Division's adequacy review letter dated June 23, 2006. The following are the
Division's comments as well as several new questions and comments:
The application form submitted with the revision states that there will be an increase in disturbed
area of 2.8 acres. Page 4 ofExhibit IX indicates there are t 6 acres of disturbance with the borrow
area, and page 11 of Exhibit IX notes that the borrow area includes 4.6 acres to reclaim. Please
determine the actual proposed disturbance acreage and revise the pages to be consistent with the
actual proposed disturbance, as required by Rule 2.03.3(2).
The Division has no further concerns. The operator explained that, of the total disturbed acreage in
the borrow area, MR-66 accounted for 1.8 acres of disturbance and TR-43 accounted for the
remaining 2.8 acres of disturbance. Also, there is no discrepancy on page 4 of Volume IX.
2. BRL has an approved topsoil replacement depth of approximately 2 feet far the cover pile, topsoil
pile, and Gob Pile 2 disturbance areas. With the addition of the borrow area, TRL now proposes a
replacement depth of 0.5'. Based on the approximately 31.5 acre proposed disturbance (gob pile.
borrow area, cover pile area and topsail stockpile area), and a reported available topsoil volume of
55,813 cubic yards, it appears that BRL would have ample topsoil available for an approximate
replacement depth of 1.1 ' of topsoil. Please explain the rationale behind the proposal to reduce
topsoil replacement depth, and how this replacement depth would comply with the requirements of
Rules 2.04.9, 2.05.4(d), and 4.06.
In the submittal dated July 7, 2006, BRL revised Appendix A of Volume IX to show that the
topsoil replacement depth will be I foot. This revised topsoil cover depth is acceptable to the
Division. However, the Division requests that the revised Appendix A of Volume IX retain the
format and detailed information of the currently approved Appendix A. The detailed information is
needed to properly determine the reclamation cost estimate. In addition please revise page 2.05-38
in Volume 1 to show that the topsoil depth wilt be 1 foot instead ofthe stated 2 feet.
3. BRL did not include an updated post-mining topography map, as required by Rule 2.O.i.4(2)(c).
Please revise Map 18, the currently approved post-mining topography map to include proposed post-
