NEWMONT <br /> GOLDCORP <br /> 2.2.7 Squaw Gulch <br /> The activities associated with Amendment 13 are not expected to have an impact on groundwater <br /> quality in the Squaw Gulch drainage as the proposed activities will be entirely on previously <br /> disturbed lands. <br /> 2.2.8 Grassy Valley <br /> The activities associated with Amendment 13 are not expected to impact groundwater in Grassy <br /> Valley. <br /> 3 WATER QUALITY MONITORING <br /> CC&V maintains an extensive monitoring and stormwater management network at the Cresson <br /> Project. Various plans have been developed by CC&V to manage and monitor surface and <br /> groundwater quality including the following: <br /> • Stormwater Management Plan, provided in Appendix 3; <br /> • Water Quality Monitoring Plan, provided in Appendix 7; and <br /> • Quality Assurance Project Plan, provided in Appendix 7. <br /> Surface water and groundwater monitoring is conducted by CC&V professional staff or outside <br /> contractors, as needed. Samples collected in connection with this monitoring program are <br /> analyzed by qualified third-party laboratories. Historical surface water and groundwater sampling <br /> data is provided as Appendix 6 to this Amendment 13 permit. Appropriate quality assurance and <br /> quality control ("QA/QC") procedures are used to validate the sample collection and analytical <br /> methods, as described in the Quality Assurance Project Plan (QAPP) and Field Sampling <br /> Guidance provided as Appendix 7 to this Amendment 13 permit. <br /> 3.1 Surface Water Monitoring <br /> Surface water quality and flow monitoring will be conducted as stated in previous submittals on a <br /> quarterly basis. The following locations are recognized as compliance surface monitoring <br /> locations: one station down-gradient of Valley Leach Facility 1 (VLF1) on Arequa Gulch (AG-2.0); <br /> one station downgradient of the East Cresson Mine area on Theresa Gulch (T-2); a station <br /> downgradient of the operations on Wilson Creek just below the confluence with Bateman Creek <br /> (WCSW-01); and two stations in Grassy Valley(GV-02, and GV-04). No surface water monitoring <br /> station is located downgradient of the VLF2 in Squaw Gulch as this is a zero-discharge facility. <br /> VLF2 Phase 3 also will be a closed loop facility. Samples collected at the surface water monitoring <br /> stations, shown in Table G-1 below, and on Figure G-1.
