Letter to Bryce Romig 2 February 22 2001 could be backfilled into the main area of Storke Yard. Since backfilling is complete and released for the main area of the yard, the cost re-estimate assumes that river channel cut will be backfilled into the 7-Shaft area. The DMG's cost re-estimate indicates that the reduction in bond amount requested in the SR-03 application based on a percentage completion of the Storke Yard backfilling and grading would create a funding shortfall for the river channel reconstruction project, and that re-estimated reclamation costs based on current conditions are the appropriate basis for determination of the bond amount. 2. E-Dump The DMG, through approval of Revision SR-03 releases CMC from reclamation liability for grading the west side of E-Dump. The costs associated with reclamation task#25 from the DMG's original 1998 estimate and in the year 2001 re-estimate have been eliminated from the amount of required bond. Reclamation costs for tasks 28 and 29, to place and spread topsoil on top of E-Dump are included in the year 2001 re-estimate 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 cost dedicated to tasks 28 and 29 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. • ran-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 CMC and is not included. 3. No. 3-Dam The DMG, through approval of Revision SR-03 releases CMC from reclamation liability for grading and capping No. 3-Dam. The costs associated with reclamation tasks 54, 55, 56, 57, 58, and 64 from the DMG's original 1998 estimate and in the year 2001 re-estimate have been eliminated from the amount of required bond. Limitations to the release of reclamation responsibility for the 3-Dam capping project are as follows: • On-going maintenance of storm water controls and repair of rills and gullies may be required on 3- Dam (see 9/26/00 inspection report). • Revegetation responsibility release was not requested by CMC and is not included. • Area C-19 illustrated on the permit amendment AM-02 map is not released (see 9/26/00 inspection report).
