sources and disposal of hydrostatic test water: The water source for hydrostatic <br />testing will be Unocal's alluvial water wells or Unocal's water withdrawal facilifij o n <br />the Colorado River south of the town of Parachute (see our response to item 6). <br />Water grralifij will be tested before running the hydrostatic test and again before the <br />water is discharged at the Parachute Site. <br />Botanical, raptor, and cultural resources clearance surveys of most of the pipeline <br />route, as determined in consultation with the BLM, were conducted during the <br />spring and summer of 1998. These surveys are described in Section 7.9, Section 7.7, <br />and Section 7.10 of the Mine Plan, respectively. The results of all three of the <br />surveys have been provided to the BLM and to Woodward-Clyde. Additional <br />surveys of certain sections (e.g., cultural survey below Davis Point to the point the <br />pipeline joins the existing 5-party corridor) may be required prior to construction. <br />19. Figure 2-3 only shows portions of these pipelines; we need the entire route if they aze to <br />be assessed. <br />20. Section 2.1.2.3, page 2-7 -Electrical power. Figure 2-3 shows three transmission line <br />routes, which aze not discussed in this section. We need an explanation. Does Figure 2-3 show <br />the entire routes? Please provide basic descriptive information on the 138-kV line -height of <br />poles (structures), type of poles/structures, number per mile (average span length), azea of <br />disturbance, permanent access roads, ROW width, azea of temporary construction disturbance, <br />azea of permanent disturbance, etc., ground to conductor cleazance, allowable vegetation height <br />under conductors, and construction methods. <br />Based on the level of detail in this request, it appears that you are assuming you will <br />need to conduct a firll assessment of the transmission line. Note that the <br />transmission line will be permitted and built by White River Electric Association as <br />part of their systern needs. BLM is or will be conducting a separate EA for the <br />transmission line. WREA has conducted field studies as required by BLM. <br />The maps that we have on the routes are attached. Our understanding of the line is <br />as follows. The power line poles will be wooden and are 70' type TT. There will be 9 <br />poles per mile with an average span between poles of 600 feet. The ground to <br />conductor clearance is 9 feet and the allowable vegetation height under the <br />conductors is 15 feet. The minimum surface of the earth to conductor clearance is 30 <br />feet where vehicle clearance is possible. The power line ROW is 100 feet. <br />11 <br />
