69ICV Powerline <br />TCC constructed a 69 KV powerline as shown on Map 24, Surface Facilities. The line provided power to the <br />• substation that powered the 8050 dragline. A trailing cable extended from the substation located near the Batch- <br />Weigh system to the dragline. Once the dragline, which is not the property of TCC, was moved from the site, the <br />trailing cable was removed. It is anticipated the substation will be removed unless needed for other applications at <br />the mine. When the powerline is no longer needed, it will be taken down and removed from the site. <br />Washplant II Powerline and Substation (TR07-59, Washolant 1T1 <br />A new 69 KV distribution line was extended approximately 300 feet from the existing 69KV line to a new <br />substation location adjacent to the Overland Conveyer. Powerline construction involved the limited disturbance <br />required to place 4 powerpoles, with pole placement avoiding the Foidel Creek buffer zone. Installation of the new <br />dedicated Washplant Substation required construction of a 40 x 60 foot concrete pad, enclosed by an 8-foot high <br />chain-link fence and installation of steel supports, transformers, and associated control and electrical switch-gear. <br />The existing 24-inch culvert, in the substation location, was extended approximately 120 feet to convey drainage <br />under the substation area. <br /> <br />i <br />TR07-59 2.05-47.1 03/26/07 <br />
