Box 483 <br />Paonia, Colorado 8]428 <br />RE: Permit Revision No. 3, Facilities Expansion and Production Increase, Bowie No. 2 Mine, <br />Permit No. C-96-083, Bowie Resources Limited <br />Deaz Mr.Beaz: <br />The Division has finished its adequacy review of Bowie Resources Limited's (BRL) October 4, <br />1999 submittal for Permit Revision No. 3. This Division adequacy letter only summarizes those <br />issues not resolved since the Division's adequacy letter dated September 24, 1999. <br />ORIGINAL TR-06 QUESTIONS <br />Geotechnical <br />BRL proposes !o construct a conveyor transfer station immediately uphill from the <br />existing haul road at an elevation of approximately 6730 feet. In order to accommodate <br />the stanchion for the transfer structure, BRL proposes to excavate a bench into the slope <br />immediately up slope from the haul road. This will create a steepened pocket-shaped 30' <br />to d0' high c:u slope. BRL should provide a complete stability analysis report for this cut <br />slope to demonstrate that it will be stable during operation and following reclamation. <br />The Division has no further concerns. BRL submitted the Terracon geotechnical stability <br />report, dated June 1999. In addition, the submittal dated October 4, 1999 included a two <br />page introduction to that report. The introduction listed the conditions requested by the <br />Division concerning the engineering evaluation and reporting requirements needed during <br />the excavation work. Also, page exh-8-29 was revised in the submittal dated October 4, <br />1999, requiring ditch linings for the ditches above the transfer station. <br />
