NEWMONT <br /> GOLDCORR <br /> Groundwater may not be encountered in some wells completed to within a few hundred feet of <br /> the surface. In these cases, monitoring will be limited to checking water levels (i.e., checking for <br /> the presence of water) and samples will not be analyzed unless sufficient water is encountered <br /> to allow sampling and analysis of non-turbid water. No additional surface monitoring locations are <br /> proposed, as VLF2 is a zero discharge facility. <br /> 3.3 Phase 3 PSSA Monitoring <br /> VLF2 Phase 3 will also have a separate Pregnant Solution Storage Area (PSSA), which will have <br /> monitoring requirements similar to existing PSSAs. Design details for the VLF2 Phase 3 PSSA <br /> are provided in Appendix 1. Monitoring requirements at the leak detection systems, the high- <br /> volume solution collection systems, the low-volume solution collection systems, the pregnant <br /> solution storage areas, and the external pond are described in Exhibit U, and various facility <br /> documents including the Water Quality Monitoring Program and the SPCC Plan (Appendix 7 and <br /> Appendix 11, respectively). The only change to VLF monitoring anticipated by Amendment 13 is <br /> the addition of monitoring requirements for the new Phase 3 PSSA. <br /> The information presented below reflects the currently approved criteria for responding to <br /> changes in operating parameters observed as a result in monitoring activities. The situations <br /> outlined below are those that require further action. <br /> • Underdrains: The 30-day running average of CNWAD monitoring data for an underdrain <br /> exceeds 1.0 mg/L and the 30-day running average pH value from monitoring data for <br /> the same underdrain for the same period exceeds 9.0. <br /> • LDS: The 30-day running average of CNwAo monitoring data for a LDS exceeds 0.5 <br /> mg/L and the 30-day running average pH value for the same LDS monitoring data for <br /> the same period exceeds 9.0. <br /> • HVSCS: The average of the water level monitoring data in the PSSAs exceeds 80 <br /> percent of the total capacity of the PSSA in a sustained manner. <br /> • LVSCS, LDCRS: The transducers monitoring data in the LVSCS or LDCRS exceed <br /> two feet in a sustained manner. <br /> The first response to the conditions listed above will be to verify that the measurements and data <br /> are accurate. This may involve re-sampling or revisiting the monitoring location to confirm the <br /> initial monitoring results. In the event that initial monitoring results are confirmed, verbal notice <br /> will be provided to DRMS. Recommendations will be provided to DRMS regarding further analysis <br /> of the situation and, if warranted, appropriate corrective actions will be developed and <br /> implemented. Corrective actions may include, but not be limited to, providing a written plan to <br /> DRMS regarding proposed measures for addressing the situation, changing flow rates to the <br /> Cripple Creek&Victor Gold Mining Company Exhibit G <br /> Cresson Project Amendment 13 <br /> 12 <br />
