<br /> <br />8.Division: <br />d the acreages <br />provided by BME. The Division currently has approved the amount of 464.86 disturbed <br />acreage and 8,095.46 affected acreage. Please provide an explanation to the discrepancies <br />between acreages specified by the Division and what BME has provided. <br /> <br />BME: The discrepancy concerning the Affected area originated from MR-156. An <br />increase of 1.56 acres was warranted due to a portion of the new roads falling outside of the <br />subsidence area. An increase of 7.22 acres was instead applied which included all proposed <br />disturbance. 5.66 acres of this disturbance was already accounted for in the Affected area <br />since it was Affected by planned subsidence. <br /> <br /> The discrepancy concerning the Disturbed area was traced back to MR-145 and <br />MR-157, which was approved after MR-158, the base acreages used came back from MR- <br />reduction <br />156. Thus eliminating the 0 .52 acres of net disturbance associated with MR-158. <br />A total increase of 4.00 acres to the Divisions last Revised Decision (MR-157) document <br />total disturbed acreage is needed. <br /> <br /> An additional 2.41 acres of disturbance was added to account for recently submitted <br />MR-159. <br /> <br /> A revised page 3 of the renewal application form is attached with the proper <br />corrections made which reflects the appropriate account of the current acreage figures. <br /> <br /> Page 4 was also updated to increase the estimated life of mine to 20 years. <br /> <br />Division <br />: The Division has reviewed all revisions that have been approved since the <br />previous renewal (RN-5). At the time of approval for RN-5, both the Divisions and BMEs <br />acreage tracking for disturbed and affected acreage for the Deserado Mine matched. <br />Reviewing each revision since RN-5, the Division has created three tables comparing <br />acreage changes requested by BME with each revision, acreage approved by the Division <br />and final adjusted acreage with corrected known errors. However, even with adjusting the <br />disturbed and affected acreages with the known errors, there still appears to be some <br />discrepancies between the Divisions calculated acreages and what has been provided by <br />BME with the renewal application. Please see the attached tables for reference. <br /> <br />Please provide additional explanation for discrepancies in disturbed and affected acreage for <br />the Deserado Mine in comparison to the Divisionrevised acreage calculations. <br /> <br /> <br />9.Division: Once the Division receives the response from BME regarding adequacy question <br />#8, an accurate updated reclamation cost estimate will be provided. As discussed with MR- <br />157, the removal of structures related to the B-Vent Shaft #2 will be removed from the <br /> <br /> <br />BME: Comments noted. <br /> <br /> <br />
