Mountain Coal Company, LLC <br />West Elk Mine <br />High Voltage Overhead Transmission Line Installation <br />Proiect Description <br />The project consists of constructing a new 12,470 volt overhead electric power transmission line <br />extension to provide electric power for new facilities within the existing disturbed area of the <br />West Elk Mine. The new line will connect to the existing 12,470 volt overhead line that feeds the <br />West Elk Mine surface facilities and will terminate at the existing Lower Refuse Pile location as <br />shown on West Elk Mine Facilities Powerline drawing. The new line installation will consist of <br />the following. <br />Installation of nine (9) new direct burial wood poles expected to be 50-55 feet high. <br />A high voltage safety switch arrangement mounted on structure 7A. <br />Approximately 1,800 feet of overhead power conductors. There will be three (3) runs of 556 <br />ASCR line, one run of 4/0 ground conductor and one run of static wire. <br />The line will be constructed entirely within previously disturbed areas. Existing light use roads <br />and trails will be used for access to the pole locations for construction. Some brush clearing will <br />be required on existing trails to allow access by line trucks for setting poles. No new light use <br />road construction is expected to be necessary for long term access to the structures. <br />09/28/09 MR 358
