• A 100 KVA transformer measuring 2 x 2 x 1.5 feet is located on the east side of the third office trailer to <br />provide power to the trailer. <br />• A short (600 feet - 3 poles) 240 volt powerline runs northwest from the County road to the Fish Creek <br />Water Treatment System settling ponds, however, while this line remains in- place, it has been replaced by <br />the distribution line from Substation S. A 400 foot extension off this distribution line (3 poles) supplies <br />power to the Fish Creek Ventilation Shaft Dewatering Borehole. A fiber -optic line was installed from the <br />coal lab to the weigh - station, located along the railroad tracks and from the lab to the main office building. <br />The new section of line along the railroad tracks is approximately900 feet long (4 poles), and was installed <br />on previously disturbed ground adjacent to an existing road. The section of line from the lab to the office <br />was hung on existing poles. <br />• TCC uses three voltage regulators to increase the electrical efficiency of its power - distribution system. The <br />regulators set on concrete pads, within a chain -link security fence, as shown on Map 24. <br />• Power for the slope -belt drive building, constructed in 1995, is provided by a buried 4,160V line running <br />between Substation 1 and the old transfer building. The line is not buried where it drops over the portal <br />highwall. <br />Capacitor Banks (MRO1 -174) <br />To enhance the reliability and efficiency of the power - delivery system to the mine, YVEA installed and maintains <br />two capacitor banks at the Foidel Creek Mine Metering location. The capacitor banks are owned by YVEA and <br />will remain after mining, as a component of YVEA's power - distribution system. Installation of the capacitor banks <br />resulted in incremental disturbance of approximately 0.2 acres for extension of the existing pad. Approximately <br />485cy (12 -18 inches), of topsoil was salvaged from the disturbance area and placed in Stockpile SF -1. A short <br />segment of Colorado Yampa Coal Company's (CYCC) drainage channel PG 1 -2 was also relocated to <br />accommodate construction. The channel was moved approximately 5 feet to the west of its current location. The <br />channel was reconstructed consistent with the design approved in CYCC's permit number C -81 -071. The pad <br />extension was constructed using approximately 700cy of select material from the refuse pile clay salvage area, <br />supplemented by off -site borrow. <br />Six 12 foot x 3 -foot diameter piers with an 18 -inch x 5 foot concrete slab, a 6 x 3 x 1.5 foot footer, and ten 12 foot x <br />3 -foot diameter piers were poured in -place to support the capacitor banks, a battery cabinet, and various dead -end <br />structures, switches, and fuse panels. A security fence was constructed around the pad to limit access to authorized <br />persons. <br />Borehole Pumn Substation <br />TCC installed the Borehole Pump Substation southwest of the PM Bay, consisting of a transfonmer, related <br />switchgear, and four powerpoles. The 50 x 50 foot area is graveled and fenced with a ten -foot high chain -link <br />security fence. The substation ties into the existing overhead 69KV line. <br />69 KV Powerline and Substation <br />CYCC constructed a 69 KV powerline to provide power to the substation that powered the 8050 dragline, in <br />conjunction with the previous surface mining operations. Once the dragline was moved from the site, the <br />associated trailing cable was removed, and subsequently both the powerline and substation were removed. <br />Washplant II Powerline and Substation (TR07 -59, MR07 -222, Washplant I1) <br />A new 69 KV distribution line was extended approximately 350 feet from the existing 69KV to the Washplant II <br />substation. Powerpole installation involved the use of existing roads or limited overland access to the individual <br />pole locations, localized shallow auger drilling to set each pole, pole placement and anchoring, and distribution of <br />the limited drill cuttings over the small area surrounding each pole. Given the very limited temporary disturbance <br />involved, TCC did not include topsoil recovery for the individual power pole locations. It should be noted that pole <br />locations were selected specifically to avoid stream buffer zones or other sensitive areas. Construction of the <br />distribution lines involved the use of existing roads or limited overland access by a bucket truck and cable truck to <br />install cross -bars, insulators and conductors. All cross -bars have installed raptor deterrents, consistent with <br />approved raptor protection guidelines. Installation of the new dedicated Washplant Substation required <br />construction of a 40 x 60 foot concrete pad, enclosed by an 8 -foot high chain -link fence and installation of steel <br />MR11 -258 2.05 -47 10/25/11 <br />
