STATE OF COLORADO <br />DIVISION OF RECLAMATION, MINING AND SAFETY <br />Department of Natural Resources <br />1313 Sherman St., Room 215 <br />Denver, Colorado 80203 <br />Phone: (303) 866-3567 <br />FAX: (303) 832-8106 <br />COLORADO <br />D IV IS I ON OF <br />RECLAMATION <br />MINING <br />SAFETY <br /> <br />INTEROFFICE Bill Ritter, Jr. <br />Governor <br />MEMORANDUM Harris Sherman <br />Executive Director <br /> Ronald W. Cattany <br />TO: Joe Dudash Division Director <br /> Natural Resource Trustee <br />FROM: Jim Star <br />SUBJECT: Bowie No. 2 Mine TR-65 Cost Estimate <br />DATE: 6 January 2010 <br />Attached is the reclamation cost estimate for the Bowie No. 2 Mine's Technical Revision <br />65 - drilling one geotechnical hole and credit for gob vent holes not drilled. The estimate <br />is 5 tasks and represents a decrease in liability of $135,569.00. This decrease is slightly <br />less than the $135,979.00 shown in the estimate submitted by BRL. The main reason for <br />this difference is the fact that BRL uses a standard percentage for indirect costs versus the <br />actual calculated indirect costs used by the Division. This always leads to a difference in <br />indirect costs and calculated liability. <br />The cost decrease comes from gob vent boreholes not drilled (and the associated drill pad <br />and light-use road reclamation). These gob vent boreholes that were removed are <br />GVB9B, GVB I OB, GVB I ODG, GVB 11 C, GVB 11 D and GVB 11 E from TR-52; drill pad <br />192 from MR-104; and GVB10B and GVB10U2 from MR-106. All reference to these <br />gob vent boreholes has been removed from Map-09, Hydrologic Monitoring Location <br />Map. <br />Please let me know if you have any questions or need any additional information. <br />cc: Sandy Brown w/out Attachments <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
