Exhibit 81 <br />Mountain Coal Company, L.L.C. West Elk Mine <br />Coal Preparation Plant and Associated Coal Handling Facilities <br />Preparation Plant <br />The Preparation Plant will be located on the existing LRP mine bench. The Preparation Plant building will be <br />approximately 40-feet wide, 109-feet long and 148-feet tall. The building will steel-sided and completely <br />enclose the washing and coal handling equipment. <br />The Preparation Plant will separate the ROM coal material into salable coal products and coal refuse. The <br />salable products will be blended in the plant as required to meet customer specifications. The refuse material <br />will be conveyed by 550-foot long, 36-inch wide conveyor PP-4 into a 300-ton truck loading bin at the <br />existing RPE coal refuse area. The truck loading bin will load off-highway trucks for distribution to the <br />existing RPE coal refuse pile. Conveyor P-6, a 200-foot long, 36-inch wide stacking conveyor and the fines <br />stockpile on the LRP allow for temporary storage of up to approximately 5,000 tons of coal and/or coal fines <br />product. If needed, the fines can be used for later blending to meet coal quality specifications, or can be <br />transported to the RPE for disposal, depending on the quality of the fines. <br />Water will be supplied to the Preparation Plant via a new 8-inch diameter buried HDPE pipeline. The <br />pipeline will tie into the FW-1 outlet south of the ST-1 coal stack tube to provide the necessary volume of <br />water to complete the coal washing process in the preparation plant. When operating at full capacity, the <br />plant is expected to consume approximately 52 gpm of raw water from MCC's existing water rights in FW- <br />1. The coal preparation plant is a closed loop system designed to produce no effluent. As a precaution, a <br />buried HDPE discharge water pipe will be installed to flow to a sediment trap to be constructed on the south <br />east corner of the bench and flow to an existing LRP perimeter drainage ditch. <br />Plant Control and Lab Building <br />The Plant Control and Lab building will be a two-story enclosed building, approximately 40-feet wide, 50- <br />feet long and 30-feet tall, on the south side of the preparation plant building. The preparation plant controls <br />and operating facilities will be housed on the top floor and third-party-operated laboratory facilities will be <br />housed on the bottom floor. The new lab facilities will replace the existing lab facilities currently located <br />near existing coal stack tube ST-4. <br />Preliminary Proiect Schedule <br />MCC is currently conducting an engineer, procure and construct (EPC) bidding process that is expected to <br />conclude with a bid award to a major EPC firm on or before September 14, 2009. <br />The facilities described above must be fully-operational by mid-July of 2010 to meet West Elk Mine's <br />operational needs. No preliminary project schedules have been developed for this project, however, in order <br />to meet the July, 2010 commissioning date, site construction activities must commence as soon as possible <br />following the bid award date. <br />08/09- TR118
