together, although they would probably not be reclaimed at the same time, as previously noted. Reclamation will involve excavation, removal, and salvage or dispose of all of the Elk Creek Culvert except for those portions approved for retention in conjunction with permanent postmining road crossings. The lower portion of the Elk Creek channel will then be reestablished through the mine disturbance area consistent with approved postmining drainage designs, and remaining disturbance areas will be regraded to a stable configuration which ties into the existing topography and adjacent reclaimed areas. Reclamation of these areas will require approximately 123,000 cy of cut and 185,500 ry of fill. The remaining 62,500 ry of excess cut from the Elk Creek Mine Surface Facilities area will be used to meet the cut/fill material balance. The only existing or proposed satellite facility requiring reclamation (other than miscellaneous water and sewage effluent facilities, exploration sites and coalbed methane well sites and roads) is the Substation No. 3 and C-Gulch Ventilation Shaft area, the Hubbard Creek Fansite area and the Bear Creek Fansite area. Reclamation of the substation No. 3 and C-Gulch ventilation area will involve recovery and distribution of approximately 5,000 ry of material from the existing overburden stockpile and regrading of the replaced material to tie into the existing topography. Reclamation of the Hubbard Creek Fansite area will require recovery and distribution of approximately 6700 yards of material from the existing overburden stockpile and regrading of the replaced material to tie into the surrounding topography. Reclamation of the Bear Creek Fansite area will require recovery and distribution of approximately 7,700 yards of material from the laydown area and regrading of the pad facility material to tie into the surrounding topography. The miscellaneous satellite facilities noted above would generally require moderate grading, which can be accomplished in conjunction with soil material replacement, and will involve a direct on-site cut/fill balance. The final postmining configurations for all mine disturbance areas are shown on the Facilities Postmining Topography Maps (Map 2.05-M6, Sheets 1 thru xx). Cuts and fills for final reclamation backfilling and grading are shown on the Reclamation Cut/Fill Isopach Maps (Map 2.05-E5-M1) and post mine cross-section Map 2.05-R5-M2. Table 2.05-E5-T2, Reclamation Cut/Fill Summary, provides a tabular summary of the volumes is shown on the Reclamation Cut/Fill Isopach Maps.
