Mountain Coal Company Exhibit 69 <br />West Elk Mine Sylvester Gulch Facilities <br />r~ <br />Reclamation <br />The total wetland impact caused by this project is estimated to be 0.69 acres. Wetland <br />impacts will be mitigated according to a plan approved by the U.S. Army Corps of <br />Engineers. <br />It is estimated that it will take approximately six months to complete ail the major steps in <br />the reclamation plan. The plan would involve demolishing the major structures first (fans, <br />hoist, substation, power poles and lines, etc.), sealing the ventilation shafts and sealing the <br />electric borehole and the degasification hole. The small facility pads (substation, <br />degasification hole, electric borehole, and the roads to these aeeas, including the powerline <br />water tank road), would be reclaimed. The Shaft #1 and #2 site, the Shaft #3 site and <br />road, and the sediment pond would be reclaimed, and then the maln/haul access road <br />would be reduced to a light-use road. As areas are reclaimed, topsoil will be replaced and <br />the aeeas seeded and mulched. <br />As the completion of the electric borehole and degasification hole included completely <br />grouting and casing the holes to prevent surface and ground water from entering the hole, <br />the holes will be reclaimed by cutting the surface casing below grade and seafing the holes <br />in accordance with Rule 4.07.3(1). <br />Reclamation of the three ventilation shafts will include removal of the hoisting facilities, <br />removal of the ventilation fans facilities and sealing of the ventilation shafts. All structure <br />foundations will be removed. The concrete collar pads will be removed from the three <br />shafts. The ventilation shafts will be sealed by constructing a steel and concrete plug ten <br />(10) feet below the ground surface that will span each shaft and support a concrete seal. <br />A concrete seal will be constructed that will fill the entire inside diameter of each lined <br />shaft and completely seal the opening from ten (10) feet below the ground surface to <br />within three (3) foot of the ground surface. Suitable fill material will be used to cover the <br />concrete seal to the level of the surrounding terrain. This sealing method will be used for <br />the three ventilation shafts and complies with MSHA regulations and is designed to <br />prevent access to the mine workings by people, livestock, fish and wildlife and machinery. <br />Drawings entitled Typical Shaft Seal -Ventilation Shaft #3, aze included in Exhibit 69. <br />The downcomer pipes for the shafts will be sealed by filling the entire hole with cement <br />grout or other similar material. <br />Reclamation will also include removing and hauling off-site CCW-1B, the Clearwater <br />diversion culvert. Because of the culvert size, it is not practical to bury it on site. The <br />culvert will either be recycled or disposed of in the local landfill. <br /> <br />All of the approximately 160,000 CY of fill material will remain within the site as the <br />SGFA is regraded to approximate original contour (AOC) during reclamation, although <br />relocation of approximately 80,000 CY of material will be required. For example, <br />approximately 20,000 CY of fill material from the shaft site azea will be used to reclaim <br />13 Nav. 1996 PR07R; Revised May 1997MR216: <br />RevisedJuC 1997MR219 <br /> <br />
