The reclamation of the RPE was approved with an average total of 18 to 24 inches of <br /> subsoil and topsoil. A variance to cover the lower refuse pile through TR43 in July, <br /> 1987. That variance was applied also to the RPE. As the RPE is graded and overed <br /> with subsoil and topsoil, it will be revegetated with the approved permanent seed mix. <br /> The seeding will be done either by broadcast or by hydroseeding and then mulched. <br /> Interim and final revegetation will be conducted in the same manner as for the lower <br /> refuse pile (LRP). The haul road for the RPE will be reclaimed at the end of mine life <br /> to approximate original contour. <br /> A small waste pile at the Lone Pine ventilation fan site was approved through technical <br /> revision #69 on August 12, 1994. The pile stores refuse from the development of that <br /> facility. It covers an area of 0.7 acres, storing 17000 cubic yards of refuse. A <br /> subdrain system was installed. The pile was covered with three feet of subsoil and one <br /> foot of topsoil and reclaimed. <br /> IX. Coal Mine Waste <br /> 1. The Division proposes to approve a plan for extinguishing coal mine waste fires. <br /> This plan has been approved by MSHA and contains provisions about who will <br /> be involved in the extinguishing operations (4.11.1). The plan can be found in <br /> Exhibit 65 in Volume 11 of the permit document. <br /> 2. No coal mine waste from the West Elk Mine is proposed to be returned to <br /> underground workings (4.11.3). <br /> 3. Disposal of non-coal waste will be handled as required (4.11.4). <br /> 4. No dams or embankments constructed of coal mine waste have been or are <br /> proposed to be constructed (4.11.5). <br /> X. Backfilling and Grading <br /> The Backfilling and Grading plan can be found throughout Section 2.05.4. Exhibit 54 <br /> of the permit document contains detailed information regarding abandonment and <br /> sealing of portals. Maps 58, 58A, 5813, and 59 show post-mining topography. <br /> During the course of MCC's study of the original West Elk lease property and the <br /> Jumbo Mountain lease area, numerous slope failures and rock falls were identified. <br /> Landslides and rockfalls identified during their study are delineated on Map 32 and <br /> 32A. However, MCC also observed that it believes such slope problems would have a <br /> minimal effect on the operation and these areas can be stabilized or removed when the <br /> facility is built. <br /> In order to judge the credibility of MCC's statements regarding slope stability, the <br /> Division requested the submittal of supporting information. MCC responded by <br /> submitting a report prepared by Geo-Hydro Consultants, Inc., entitled "Landslide <br /> 52 <br />
