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 />INTEROFFICE <br />MEMORANDUM <br />TO: Joe Dudash <br />FROM: Jim Stark <br />SUBJECT: Bowie No. 2 Mine TR-66 Cost Estimate <br />DATE: 8 January 2010 <br />COLORADO <br />D IV IS I ON Of <br />RECLAMATION <br />MINING <br />SAFETY <br />Bill Ritter, Jr. <br />Governor <br />Harris D. Sherman <br />Executive Director <br />Ronald W. Cattany <br />Division Director <br />Natural Resource Trustee <br />Attached is the reclamation cost estimate for the Bowie No. 2 Mine's Technical Revision <br />66 - Terror Creek Vent Shaft and associated structures. The estimate is six tasks (a <br />summary sheet and tasks 221-225) and represents an increase in liability of <br />$208,818.00. This increase is slightly less than the estimated liability of $225,324.00 <br />submitted by BRL. The main reason for this difference is the fact that BRL used a <br />different diameter for the poured-in-place concrete cap for the vent shaft (a diameter <br />larger than the one used by the Division). As always, we will use the Division's <br />estimated liability on the coding form. <br />If there are any changes to the plans as a result of the adequacy review please let me <br />know, as a recalculation of the liability may be warranted. Please let me know if you <br />have any questions regarding this estimate 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
