r~ u Due to previous contamination and misuse by the Staley Gordon Mine, there is no suitable topsoil in the area to be saved. A dozer was used to level the space and form a two foot berm for sediment control at the low elevation of the site. During final reclamation (2001), the site was restored to blend into the natural slope. Four inches of topsoil was imported from the haul road topsoil stockpile #3 and spread on the site. Table V-4 reflects importation of topsoil. After topsoil has been spread, the seed mixture as shown in Table V-14 was planted. Reclamation standards in the permit that apply to reclamation of the ventilation entry will also apply to the material storage site. The D Portal area surface facilities, Map 15, shows the various buildings and structures comprising the D Portal area. The Administrative Building is currently used mainly for storage and most administrative and technical support personnel offices are in the Change House. In addition to these buildings are areas for parking and storage, mobile equipment maintenance, mine entrance portals and the coal handling, preparation and storage facilities. Sedimentation control is provided by two methods. First, as much as possible, runoff is prevented from entering the disturbed areas by the use of interceptor ditches that divert the runoff. Second, • runoff from these areas is captured and held in sedimentation ponds. III.D Utilities III.D.1 Electric Power Suooly Electric power to the mine is provided by the Moon Lake Electric Association. Permanent power is supplied by tapping a 138,000-volt line in the SW1/4 of Section 7, T2N, R100W to a substation located near the D Portal Area. This substation, rated at 20 MVA transforms the power down to 13,800 volts for distribution to the various points of use at the mine. During October and November of 1986, Moon Lake Electric Association installed an additional three phase 480 volt power line from Conveyor Transfer Station 1 to the coal refuse areas. Raptor proof poles were placed approximately 300 feet apart located about fifty feet off the east edge of the refuse haul road. Power was needed for lighting at the refuse area to allow 24 hour operation. An 800' single phase 120 volt powerline was to extend off this line to serve a proposed air monitoring site across the haul road from Red Wash Reservoir No. 2. Colorado Air Pollution Control Division has waived such air monitoring requirements. Moon Lake used its standard equipment to drill holes, set the poles and hang the line. Equipment traveled across undisturbed ground. No surface preparation was performed since this would probably create more I. Midterm Review (812002) III-33
