A compiled reclamation cost estimate was developed by the Division as a part <br /> of the Permit Renewal No. 8 process issued on February 25, 2023. The Division's reclamation <br /> costs have been updated since that date. Per Rule 3.02.1(6), Colowyo has elected to file a <br /> cumulative bond schedule for the permit term and not the life of the Mine. For the worst-case- <br /> scenario at Colowyo,the Division has determined the reclamation liability for the 2023 - 2028 <br /> permit term is $134,625,646.00. The previous worst-case-scenario at Colowyo was <br /> $117,304,293.00. The difference between this amount for the worst-case-scenario and the <br /> previously calculated worst-case-scenario bond reported is an increase of$17,321,353.00. <br /> Therefore,with a bond held in the amount of$119,000,000.00 by the Division, the Division has an <br /> insufficient amount in bond monies to assure completion of the remaining reclamation work at the <br /> Colowyo Mine if the work had to be performed by the Division,including the cost of reestablishing <br /> vegetation on any revegetated areas, should those areas fail. The Division will initiate a surety increase <br /> revision pursuant to Rule 3.02.2(4) and provide the permittee with an opportunity for an informal <br /> conference on the adjustment pursuant to Rule 3.02.2(4)(a). <br /> This concludes the Division's Midterm Review No. 9 for the Colowyo Mine. <br /> Colowyo Coal Mine -13- 5/5/2025 <br />
