Sherman <br />' Executive Director <br />/~ Ronald W. Cattany <br />FROM: Joe Dudash ~1, 1~ Division DireROr <br />U Natural Resource Trustee <br />RE: Bowie No. 2 Mine, Permit No. C-1996-083, Bowie Resources LLC <br />Technical Revision No. 47, Hubbard Creek Vent Shaft and Incidental <br />Boundary Change, Adequacy Review <br />I am requesting your assistance in the adequacy review of the reclamation cost estimate <br />for Technical Revision No. 47 (TR-47), for the Bowie No. 2 Mine. In TR-47, Bowie <br />Resources LLC (BRL) is proposing to construct a vent shaft with support structures. <br />Also, the permit area is being increased by about 19 acres to accommodate the site. Total <br />disturbed acreage at the site will be 1.8 acres, but 0.6 acres was previously approved to be <br />disturbed through MR-75, Geotech Hole. Therefore, 1.2 acres will be disturbed under <br />TR-47. <br />The vent shaft will be constructed from the top down and will be 18 feet in diameter and <br />600 feet deep. Sediment control for the site will include a pond, three ditches, one culvert <br />and a berm. Topsoil will be stockpiled on the cut slope. <br />Attached is a complete copy of the submittal. Sorry I'm very late in getting this to you. <br />The submittal was received at the Division on March 12. The adequacy due date is April <br />19, 2007. I will probably be in the field April 16 through April 19. If you could get a <br />response to me by April 20, that would be great. There is no problem if you need <br />additional time. BRL still has to conduct a cultural resources survey of the area. If you <br />need additional information, please let me know. Thanks for your help. <br />Attachments <br />cc: Sandy Brown (without attachments) <br />c:/word/bowie2/tr47memo 1 <br />Office of Office of <br />Mined Land Rxlamation Denver Grand Junction Durango Active and Inactive Mines <br />
