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 and scalping facility to provide coal material feed from the existing ROM coal storage <br />system to the preparation plant. <br />• A coal refuse handling system from the preparation plant to the coal refuse disposal area. <br />• An addition to the product storage system for the salable plant products that provides for blending <br />with the existing crushed /screened products and reclaim to the existing unit train loadout. <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, -1,004, -L007 and -L008. All facilities <br />will be steel structures on reinforced concrete foundations. <br />Loader -Fed Hopper, Conveyor TC -1, and TC- 1 1PR -2 Transfer Tower & Scalping Station <br />Conveyor TC -1 is a 350 -foot long, 36 -inch wide conveyor belt designed to convey ROM coal material from <br />a dozer /loader -fed hopper near the ROM coal stack tube ST -1 stockpile to the TC- 1 /PR -2 Transfer Tower & <br />Scalping Station. The Transfer Tower & Scalping Station, expected to be approximately 20 feet wide by 40 <br />feet long by 50 feet tall, will house a single 8' wide by 24' long vibrating screen to remove the oversize coal <br />material and drop it into a concrete walled pit at ground level. ROM coal material that passes through the <br />screen will be directed onto plant feed conveyor PR -2. <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 & Scalping Station to the Preparation Plant located on the <br />LRP mine facilities bench (LRP). This conveyor will follow the ground for approximately half its length and <br />will be elevated using bent (open structural -steel support) structures of varying length for the other half of its <br />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 />08109- TR118; Rev. 09109- MR357 <br />
