Exhibit 81 <br />Mountain Coal Company, L.L.C. West Elk Mine <br />Coal Preparation Plant and Associated Coal Handling Facilities <br />Purpose <br />The purpose of the coal preparation plant and associated coal handling facilities is to provide the following. <br />• A coal preparation facility to improve the quality of a portion of the raw, run-of-mine (ROM) coal to <br />meet Mountain Coal Company, LLC's (MCC) customers' coal quality specifications. <br />• Conveyors to provide coal material feed from the existing ROM coal storage system to the <br />preparation plant. <br />• A coal refuse handling system from the preparation plant to the coal refuse disposal area. <br />Proiect Description <br />The coal preparation plant and associated coal handling facilities described below will be constructed <br />entirely within the existing disturbed area of the West Elk Mine located on MCC property. These facilities <br />are shown on drawings CPP CONST-PLAN and CPP -L002, -L003, -L004, -L007 and -L008. All facilities <br />will be steel structures on reinforced concrete foundations. <br />Loader-Fed Hopper, Conveyor TC-1, and TC-11,PR-2 Transfer Tower <br />Conveyor TC-1 is a 350-foot long, 36-inch wide conveyor belt designed to convey ROM coal material from <br />a loader-fed hopper near the ROM coal stack tube ST-1 stockpile to the TC-1/PR-2 Transfer Tower. This <br />transfer tower is expected to be approximately 20-feet wide, 20-feet long and 40-feet tall. The ROM coal <br />material will be transferred from the TC-1 conveyor to the PR-2 conveyor described below within an <br />enclosed portion of this tower. The tower is designed large enough for oversized-material scalping <br />equipment to be added at a future time. <br />Plant Feed Conveyor PR-2 <br />Conveyor PR-2 is a 2,000-foot long, 48-inch wide conveyor designed to convey ROM coal material from <br />conveyor TC-1 via the TC-1/PR-2 Transfer Tower to the Preparation Plant located on the LRP mine facilities <br />bench (LRP). This conveyor will follow the ground for approximately half its length and will be elevated <br />using bent (open structural-steel support) structures ofvarying length for the other half of its length. <br />A geotechnical investigation was conducted to reassess the site stability and determine the best location and <br />alignment of the conveyor PR-2 corridor, along with recommended stabilization measures. As a result of the <br />investigation, it was determined that a bench excavated along approximately 900'of the alignment would aid <br />the overall stability of the site and conveyor structures. The bench will be an average width of approximately <br />36-feet and a total average width (including cutslopes) of approximately 56-feet. Redisturbance of the <br />hillside north of the existing stacktube bench access/haul road will be minimized by moving the road to the <br />south. <br />A total of 40 foundation/support locations are expected to be constructed. Each support location will have <br />two 30-inch diameter by 40-foot deep drilled, reinforced concrete piles installed on the downslope side to <br />provide for stabilization of each conveyor support foundation. Refer to the attached geotechnical <br />investigation and recommendations memo for more detailed information. <br />08/09- TR118
