building and the maintenance-warehouse shop building. In addition to these buildings are areas for <br />parking and storage, the mine entrance portals and the coal handling, preparation and storage <br />facilities. <br />Sedimentation control is provided by two methods. First, as much as possible, runoff is prevented from <br />entering the disturbed areas by the use of interceptorditches that divert the runoff. Second, runoff from <br />these areas is captured and held in sedimentation ponds. <br />I.D Utilities <br />I.D.1 Electric Power Supply Electric power to the mine is provided by the Moon Lake Electric <br />Association. Permanent power is supplied by tapping a 138,000-volt line in the SW1/4 of Section 7, <br />T2N, R100W to a substation located near the D/B Portal Area. This substation, rated at 20 MVA <br />transforms the power down to 13,800 volts for distribution to the various points of use at the mine. <br />During October and November of 1986, Moon Lake Electric Association installed an additional three <br />phase 480 volt power line from Conveyor Transfer Station 1 to the coal refuse areas. Raptor proof <br />poles were placed approximately 300 feet apart located about fifty feet off the east edge of the refuse <br />haul road. Powerwas needed for lighting at the refuse area to allow 24 hour operation. <br />In anticipation of possible future power requirements for the B-Seam ventilation area, approximately <br />3400 feet of overhead electric utility lines may be installed. Raptor proof poles will be used to minimize <br />electrocution hazards. At the end of the mine life, the poles and powerline will be dismantled and <br />disposed of. <br />I.D.2 Water Supply Water for the mine was initially obtained through alluvial wells. The well water <br />was very high in salinity. Hence, the water is now primarily obtained from a surface lagoon created <br />near the well houses. The lagoon collects water from the White River. BME has all the necessary <br />water rights to pump this water and use it for industrial purposes. This water is delivered by pipeline to <br />the D Portal Area. <br />A portion of the water pumped to the D Portal Area is treated by areverse-osmosis water treatment <br />plant and stored in a 40,000-gallon tank for use as potable water. The remaining portion is pumped <br />directly into a 1,600,000-gallon head tank. Water from this tank is used as makeup water in the <br />preparation plant as well as fire protection and dust suppression water throughout the mine and <br />surface facilities. <br />Rio Blanco County Special Use Permitit87-1 <br />Exhibit6-Mining Plan <br />September2000 <br />18 <br />
