• 4.0 CONSTRUCTION SEQUENCE <br />Construction specifications aze included in Appendix C. This section presents a summary of the <br />construction sequence for completion of the evaporative spray facilities. <br />4.1 Phase 1 <br />The first phase of construction will consist of grading the holding pond, the evaporative spray <br />area, and the diversion channel. The grading plan is shown on Drawing 4. Existing wells within <br />liner azea (BF-2 and BF-6) will be preserved for continued monitoring and possibly as a source <br />for pumping. Excess cut material from the grading will be used to construct the holding pond <br />berm. The berm will be placed and compacted in accordance with the construction <br />specifications presented in Appendix C. Afrer rough grading is completed the azea will be proof- <br />rolled and visually inspected in accordance with the construction specifications. Rocks and <br />deleterious material protruding more than an inch above the required grade will be removed to <br />avoid puncturing the synthetic liner. <br />In general, the diversion channel will follow the slope of the evaporative spray area. The <br />dimensions of the diversion channel were presented in Section 3 and shown on Drawing 5. Cut <br />material from the diversion channel will be used to construct the berm where required (see <br />Drawing 5). The berm will be placed and compacted in accordance with the construction <br />specifications. <br />4.2 Phase 2 <br />Phase 2 will consist of construction of the concrete slabs for the evaporative sprayers. The <br />concrete slabs will be constructed in accordance with the specifications in Appendix C. Due to <br />the weight of the evaporative sprayers, they will be mounted on the concrete slabs prior to <br />placement of the synthetic liner. <br />4.3 Phase 3 <br />Phase 3 will consist of synthetic liner placement and anchoring, and facilitation of the pumps and <br />delivery lines for the evaporative sprayers. The liner anchoring details are shown on Drawing 3 <br />Ba++(e ~tfoun+ain Resources, /nc. DRaF1' Shepherd hfiller, /nc. <br />p:1+00'6,e.ap pnxLs~epon.Juc 4-I May 11, 1999 <br />
