Letter to BUce Romig 3 April 12, 2001 DRAFT River channel, including cut and fill balances and channel configuration details, may be required as a technical revision to the permit as a result of the observations made during the pending inspection. DMG currently holds $292,930.00 in bond for the backfilling and grading of Storke Yard and reconstruction of the Arkansas River channel (see sections 4.1 and 4.15 of the February 1999 Climax estimate). The SR-03 application requests Bond reduction in the amount of$155,381.00 for the reclamation completed to date in the Storke Yard. DMG's estimated costs for the completion of reclamation earthwork in the Storke Yard, assuming that the Arkansas River cut material can be blended and backfilled adjacent to the channel, is $175,543.00 (see inspection report dated September 26, 2000 and attachments). The DMG estimate yields a bond reduction of$292,930.00 - $175,543.00 = $117,387.00 for the Storke Yard. The total bond amount required as a result of the approval of SR-03 will reflect this reduction as detailed below. 2. E-Dump The DMG, through approval of Revision SR-03 releases Climax from reclamation liability for grading the west side of E-Dump. The bond amount of$409,165.00 dedicated to this grading project based on the February 1999 Climax estimate is subtracted from the total bond amount required as a result of the approval of SR-03 as detailed below. Climax requested further reduction in bonding for E-Dump to reflect extensive topsoil placement completed on E- Dump in conjunction with the Eagle Park Reservoir Project. DMG currently holds $12,124.00 bond for E-Dump topsoiling (section 4.4, 1999 Climax estimate), and has determined that this topsoiling bond should remain in place even though extensive topsoil placement above and beyond reclamation permit requirements has already occurred on the dump's west side. The E-Dump topsoiling cost is not deleted from the amount of required bond because the topsoil that this cost applies to remains in stockpile, and if it is not spread on E-Dump it will be used to enhance revegetation potential elsewhere on the affected land. Removing the E-Dump topsoiling cost from the bond could compromise the assurance that all of the topsoil stockpiled for reclamation at Climax could be put to beneficial use. Limitations to the release of reclamation responsibility for the west side of E-Dump are as follows: • Topsoiling requirement remains in place as discussed above. • On-going maintenance of storm water controls, repair of rills and gullies, and improvements to manage potentially acidic seepage may be required on E-Dump (see 9/26/00 and 8/30/99 inspection reports). • Revegetation responsibility release was not requested by Climax and is not included. 3. No. 3-Dam The DMG, through approval of Revision SR-03 releases Climax from reclamation liability for grading and capping No. 3-Dam. The bond amount of$735,691.00 dedicated to this grading project based on the February 1999 Climax estimate is subtracted from the total bond amount required as a result of the
