2.05-84 Rev. 11/96- PR07; 04/06-PR10; 12/14- TR136, 04/24 – TR153 Timing and locations of topsoil removal and replacement within the upper refuse disposal and the facilities site are shown on Map 56 and Map 57. It is uncertain at this time however, when (or if) the upper refuse disposal site will be constructed. The timing of topsoil removal and replacement within the lower waste coal disposal site is described in Exhibit 51. Reclamation of the Refuse Pile Expansion disposal area will begin promptly as each phase of deposition of the refuse coal is completed and will follow the procedures described in the Reclamation Methodology Section and in Exhibit 50 and Exhibit 51. The Lower Refuse Pile will be used as a storage area and will be reclaimed when no longer required for a storage area. Refuse pile compaction and stabilization, topsoil replacement, and revegetation will occur as portions of the refuse disposal areas are completed. Disposal in the designated areas are also discussed in the Reclamation Methodology Section, Exhibit 50, and Exhibit 51. The surface facilities site and other disturbed areas at the West Elk Mine will be reclaimed as described in the Reclamation Methodology Section. Permanent reclamation of operational areas will not commence until actual mine operations cease. Table 41A provides a timetable for the major reclamation tasks, other than reclamation of the refuse piles. Removal of the sedimentation ponds is not included, as they will not be removed until vegetation has been established following completion of the major reclamation tasks.
