associated disturbance will be minimal and should require no additional sediment control. Locations of the <br />~ttec[ed powerpoles and substations may be found on Map 39 (Substation and powerline Locations) and map 24 <br />• (Surface Facilities). <br />l'he powerline to supply the prep plan[ will run from the existing 69KV to [he prep plant site as shown on Map 24, <br />Surface Facilities. The po++•er line will run overhead from the existing powerline to a pointjust north of Haul Road <br />l3 +vhere it will be buried. This power line will require [he installation of five new power poles. <br />Power for the Eastern Mining District (EMD) vent shaft will be provided by an above-ground 3-phase 12,470 volt <br />line. The line will run west 8,200 feet from a switch box a[ the Mine 3 warehouse. The line will have <br />approximately 28 poles. Installation will occur in early winter over ahvo-week period. The location of all <br />proposed prnverlines for the EMD are illustrated in Figure 16C. <br />A 7,200 volt powerline supply for the EMD Dewatering Borehole will run from Substation # 2 approximately one <br />mile east-northeast to the site. The line will require 18 to 20 powerpoles. Installation will occur in early winter <br />over ahvo-week period. The line will be buried for 250-350 fee[ across the right-of-way of the 110,000 volt <br />WAPA line and the two 245,000 volt lines. A rubber-tired trencher will dig an 8-inch wide trench 2-3 feet deep. <br />"the soil will be re-laid in the trench over the line. <br />"there will be a short 240 volt powerline which will run northwest from [he county road to the proposed location of <br />the settling ponds. The length of this line will be approximately 600 feet and will require 2-3 poles for installation. <br />A liber optics line will be installed from the newly constructed lab to the weigh station located on the raihoad <br />tracks. This section of the line is approximately 900 feet long and will require the installation of 3-4 poles. The <br />• poles will be installed on previously disturbed ground adjacent to an existing road. The line will [hen travel in two <br />directions from [he lab: south to the office complex and west to the new loadout facilities. Existing poles will he <br />utilized to carry the cable to dtese locations. There is a need to install one additional pole on disuirbed ground <br />adjacent to the existing overland conveyor. The locations of the proposed poles can be seen on Map 24, Surface <br />Facilities and Freshwater Systems. <br />"fCC will utilize the existing road system when possible while establishing powerline. TCC does not intend to <br />develop roads to facilitate access along [he line unless wet conditions warrant it. In the even[ further preparatory <br />work is required, the available topsoil, usually 24", will be windrowed to [he side of [he road in a stable <br />configuration and stockpiled for use during reclamation of the road. In the event road drainage becomes an issue, <br />small waterbms will be constructed to divert flow from the road. <br />The powerline to supply the pump station located at Pond A +vill tie into the existing 4160 V powerline as shown <br />on Map 24, Surface Facilities. Existing access roads will be utilized as much as possible to gain access [o the <br />power pole sites. Cuttings from the augured holes for the power poles will be scattered around the sites to <br />minimize disturbance. Power poles will be places on 500' - 800' centers. <br />Power for the slope belt drive building constructed in 1995 +vill be provided by a buried 4,160 volt line runnin, <br />between the substation and the old transfer building. The line will not be buried for its descent down the portal <br />highwal I. <br />Substation Cxnansion <br />• The existing substation, located inunediately above and to the north of [he portal, +vill be expanded to allmv <br />msmlla[ion of a transformer, power poles and line, associated building, and fencing. The transformers and <br />building will be enclosed by fencing. It is anticipated that four additional po+ver poles will be installed at the site. <br />Upon completion of mining activities, when [he system is no longer required. the system will be removed. <br />ntR 97-I ~a 2.0>-a7 Re+•is'cd 9/9/97 <br />
