The Division agreed with BRL concerning both of their questions so the reclamation cost estimate <br />was revised accordingly. Enclosed are updated cost estimate worksheets that will need to be <br />inserted into the original cost estimate worksheets. The replacement pages include the cost <br />summary (2 pages) and tasks 00a, 00k, 015 and 165 (12 pages). The new liability for the Bowie <br />No. 2 Mine is $8,706,741.00. This is a decrease of $311,662.00 from the previously calculated <br />2009 Midterm estimate of $9,018,403.00. <br />The first question involved the calculation of the structural demolition costs for task 165. It is <br />correct that several of the line items were incorrectly calculated. The entire worksheet was checked <br />and no other errors (besides those pointed out) were found. The new cost for structural demolition <br />task 165 is $1,495,185.00. This is a decrease of $188,089.00 from the previous structural <br />demolition task worksheet cost of $1,683,274.00. <br />The second question dealt with the backfilling volumes for the B-seam portal bench. It is correct <br />that the volume for task 015 was overstated by 55,000 cubic yards. The original estimate used a <br />volume of 87,000 cubic yards while the revised estimate uses a volume of 32,000 cubic yards. The <br />new cost for task 015 is $39,749.00. This is a decrease of $68,317.00 from the previous task 015 <br />cost of $108,066.00. <br />The remaining cost decreases not accounted for at the task level were due to the decrease in the <br />indirect costs. <br />Please inform the Division in writing whether or not BRL agrees with this revised reclamation cost <br />estimate. <br />If you have any questions, please call me. <br />Sincerely, <br />E <br />Joseph J.
