Support Facilities and Utility Installations. All support facilities used in connection with the <br />operation of the mine, including but not limited to, mine buildings, equipment storage facilities, <br />sheds, shops and other buildings will be designed, constructed or reconstructed and located to <br />minimize or control erosion and siltation, water pollution and damage to public or private property. <br />Services which run through, pass over, or under the permit area, consisting of power, sewage, <br />water, and telephone lines, and wells will be protected against damage or relocated to prevent or <br />minimize the disruption of service. <br />Irrigation System. An electric irrigation pump is located in Calamity Draw, near Pond 007. It pumps <br />water into an aluminum or PVC pipe system that distributes water to several side roll sprinkler <br />systems. A second irrigation pump station has been established along the north permit boundary <br />to furnish additional irrigation water to the irrigation system, see Map 2.05.3(3) -1 for locations. This <br />irrigation system will enhance the revegation on the irrigated pastureland portion of the final <br />reclamation. <br />All information on topsoil and overburden stockpiles are given in Section 2.05.4. <br />12. Special Features <br />Pit Turn Slot Cut. A 115 ft wide slot cut of is needed on the east side of 27.00 Road as mining <br />proceeds north to the outcrop from the year 2000 -2003. The west slope of the slot cut will be near <br />vertical since it will be a highwall. The east slope of the slot cut will be the angle of repose of the <br />backfill, which is approximately 40 degrees. The 115 feet wide distance is the opening at the <br />bottom of the cut. The slot will begin approximately 630 feet south of the intersection of BB Road <br />and 27.00 Road and will extend about 920 feet north of the intersection. The total length of the slot <br />cut is about 2330 feet. This open "turn" slot is necessary to allow for a safe truck - shovel working <br />area and for the overburden push dozer(s) to dump their spoil off the coal edge when the mining <br />operation turns from the southern end of the BB Detour Road and advances westward. Map <br />2.05.3(3) -2 shows a typical cross section of the Pit Turn Slot Cut. WFC plans on making up the <br />deficit backfill volume this cut will create when it mines west of 27.00 Road and the overburden <br />depth increases. WFC anticipates that by the end of 2004 the slot cut will be backfilled, graded and <br />topsoiled by the normal ongoing mining processes. At that point a revision for bond reduction will <br />be proposed. As of the Mid Term Review of 2006, the slot cut has been mined through and <br />reclaimed. No future slot cuts are planned for the operation. <br />(Revised May 2014) 2.05.3(3) -45 <br />
