Southfield C1981014: MT6 9 February 19, 2013 <br />Refuse Disposal Area <br />Coal preparation resulted in coarse and fine coal refuse which was placed in a permanent <br />stockpile located on the mine site. Design capacity for the pile is approximately 3.8 million <br />cubic yards, with approximately 3.5 million cubic yards utilized at present. Geotechnical <br />stability analysis was conducted in 1981 by the original permittee, Dorchester Coal, Inc. The <br />report can be found in Exhibit 18 of the permit application package. In addition, an analysis <br />of soil suitability for growth medium and revegetation success was conducted in 1988 (see <br />Exhibit 9 of the permit application package). Two rock underdrains have been constructed <br />beneath the refuse pile to properly dewater the refuse pile and contribute to slope stability. <br />Both coarse and fine materials were disposed of in the refuse pile. Fine materials were <br />initially dewatered to facilitate their consolidation after final deposition and compaction. The <br />pile has been approved to be at the height of 75 feet while retaining a factor of safety greater <br />than 1.5, with surveys of the pile indicating a height of no greater than 70 feet. The <br />Southfield Mine began contemporaneous reclamation of the pile in 1983 when the eastern <br />side of the pile was topsoiled and revegetated. The refuse pile reclamation was completed <br />by covering the remaining pile area with four feet of noncombustible cover, then topsoil, <br />seeding and mulching. <br />Shrub and tree saplings have been planted on the refuse pile with limited success due to <br />deer and elk foraging on the tender transplants. EFCI has planted shrub clumps on the <br />reclaimed area (see Map 33 — Southfield Reclamation Plan). Transplants have included <br />junipers, ponderosa pines, skunkbrush sumacs, red cedars, mountain mahoganies and <br />pinion pines. <br />Reclamation of the Loadout <br />Reclamation of the loadout began with backfilling and regrading the area between July and <br />November 1996. A complete application for Phase I Bond Release was approved on November <br />4, 1997. The loadout was reseeded in 1997 and, after what the Operator deemed inadequate <br />vegetation, again in 1999. Upon submittal and approval of a Phase II Bond Release for the <br />loadout, the Operator will remove all of the surface water control structures and grade these <br />areas to approximate original contour. Topsoil will be spread on these areas followed by <br />seeding and mulching. <br />Roads <br />There are no haul roads at the Southfield Mine site or loadout. All coal was loaded into highway <br />haulage trucks within the open mine yard which extended to County Road 92. <br />The mine has one access road to and from the mine refuse disposal area, which extends from <br />County Road 92 to the refuse pile. All the permitted roads for the mine site can be found on Map <br />18 of the PAP. The access road was constructed in 1982 and is maintained in compliance with <br />
