<br />Earthmoving techniques for the natural gas pipeline will follow generally accepted <br />practices. The line will be left in place at the end of the Yankee Gulch Project. <br />Electric White River Electric Association, Inc. plans to permit and build a new 138- <br />kV transmission line as part of its system needs. Therefore, although this line would <br />also provide electric power to the Piceance Site, it is not directly associated with the <br />Yankee Gulch Project. There are two potential alternate routes being considered. The <br />BLM will be preparing a separate EA to assess the potential impacts from the <br />transmission line. The line would be pole mounted and located along the well field <br />access road in the 0-5 year mining panel. <br />Natural gas emergency generators will be available to supply electricity for an orderly <br />shutdown during an outage or other unforeseen emergency situations. Emergency <br />generators will be located within the initial processing plant area. <br />Pumping Station and Transformers Pumping stations may be located on the <br />western edge of a mining panel, depending on the distance between the mining panel <br />and the initial processing facility. Pumping stations will be skid-mounted and will <br />contain pumps and a control panel. The equipment will be housed in a metal building <br />on an area measuring 48 feet by 16 feet. Two skid-mounted to reduce the voltage from <br />the 15-kV distribution line will also accompany each pumping station. The total <br />disturbed surface area for the pumping stations is included in Table D-1. <br />Septic System Raw sewage will be discharged to an on-site septic system. The <br />septic tank and sewage leach field at the Piceance Site will be located approximately 50 <br />feet north of the northwest fence line of the processing plant, near the west edge of the <br />plant. The septic tank will have an approximate capacity of 1,500 gallons. The leach <br />field will extend off the north edge of the tank and will contain five 90-foot-long leach <br />pipes, spaced at approximately 10-foot centers. <br />Water Potable water will be trucked to the site, and process water will be <br />provided the return water pipeline from the Parachute Site. Water information is <br />provided in Exhibit G, Section G.4. <br />D.2.6.2 Parachute Site Utilities <br />Natural Gas An existing natural gas pipeline will serve the Parachute Site. It <br />enters the project from the east. <br />Electric Public Service Company of Colorado will provide electric power to the <br />Parachute Site via an existing 230-kV line originating from its Parachute Substation. <br />One existing substation at the Parachute Site would be refurbished/reconstructed, and <br />a new secondary substation would be constructed to serve the process building. <br />D-10 <br />
