Sherman <br />Executive Director <br />Ronald <br />TO: Joe Dudash W. Catt <br />Division Director <br />or <br />Natural Resource Trustee <br />FROM: Jim Stark <br />SUBJECT: Bowie No. 2 Mine's MR-108 Cost Estimate <br />DATE: 6 August 2009 <br />Attached is the reclamation cost estimate for Bowie No. 2 Mine's Minor Revision 108 - <br />installation of a Quonset but at the Hubbard Creek Fan site. The estimate is two tasks (a <br />summary sheet and task 351) and represents an increase in liability of $7,249.000. The <br />Division's estimate is slightly more than ($169.00) the estimate submitted by BRL (of <br />$7,080.00). The reason for this is the Division recently updated the costs in CIRCES and <br />BRL is still using the older costs. <br />One item of note is that this estimate was calculated with the assumption that the <br />structure that Bowie would be building is, in fact, a "real" Quonset hut. If not, the <br />demolition costs will increase slightly (approximately $1,000) due to the increase in <br />building volume for a "regular" building versus a Quonset hut. <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 lunction • Durango Artivo. and InartivP Mina
