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 />Date: June 30, 2011 <br />To: Susan Burgmaier <br />From: Joe Dudash <br />RE: Bear No. 3 Mine, Permit No. C -1981 -033, Bear Coal Company <br />Partial Phase One Bond Release, SL -4, Request for Assistance <br />STATE OF COLOFADO <br />As we had talked about previously, I am requesting that you recalculate the reclamation cost estimate <br />for the Bear No. 3 Mine, using the new CIRCES with the updated unit costs. As you had mentioned in <br />your memo dated December 29, 2010 for the Partial Phase One Bond Release (SL -4), the unit costs <br />that you had used to calculate the reclamation cost estimate had not been updated by the Division since <br />the December 9, 2009 cost estimate. The Division will need to know the reclamation cost estimate with <br />the updated unit costs in order to further evaluate the Bear Coal Company bond situation. <br />If you need any additional information, please let me know. Thanks for your assistance. <br />cc: Sandy Brown <br />c: /word2007/bear3 /sl4memo2 <br />Office of <br />Mined Land Reclamation <br />COLORADO <br />D I V I S I O N O F <br />RECLAMATION <br />MINING <br />— &— <br />SAFETY <br />John W.
