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