~, , <br />SMITH WILLIAMS CONSULTANTS, INC. <br />• <br />Figure 8 presents the volume time series for the new Phase 5 PSSA. The capacity of the Phase 5 <br />PSSA was calculated based on the average ore depth presented- in the ore-stacking plan <br />presented in Figure 3. The average ore within the PSSA is 300 feet. Using the load-porosity <br />relationship for Cresson ore presented in Appendix B, this corresponds to a porosity of 0.32, and <br />yields a pore volume of 74.5 MG at an elevation of 9,765 feet. Eighty percent of the total Phase <br />5 PSSA volume is 59.6 MG, which corresponds to an elevation of 9759.8 feet. As shown, the <br />Phase 5 PSSA is predicted to fully contain all solutions, including contingency inflow, reporting <br />to the PSSA. <br />The results of the water balance shown in Figures 5 through 8 show that all of the PSSAs will <br />fully contain operational and contingency flows,. therefore no solution is predicted to report to <br />the ESP, with the exception of precipitation falling onto the pond footprint. The ESP has a <br />maximum available storage capacity of 22.5 MG at the top of the berm (El. 9416.7). Figure 9 <br />presents the volume time series for the ESP. <br />• <br />• <br />S:\PROJECTS\1125 CCBV PHASE S VLF\H2 - DESIGMAREQUA VLF\VLF PHASE 5 FINAL REPORT V2.DOC 46 <br />
