2. Monitoring Plan <br /> Contained in Amendment 11 to the Cresson Permit M-1980-244, is the currently approved groundwater <br /> monitoring plan for the CC&V mine site. This monitoring plan identifies the locations for groundwater <br /> monitoring, the frequency of monitoring, and analyses to be performed. Section 11.2 of the groundwater <br /> monitoring plan states the following: <br /> "Groundwater quality and depth to groundwater is monitored on a quarterly basis at the <br /> following locations: downgradient of the AGVLF in Arequa Gulch (CRMW-3A and <br /> CRMW-3B) and Wilson Creek(WCMW-3 and WCMW-6); downgradient of the SGVLF in <br /> Squaw Gulch (SGMW-5); downgradient of the East Cresson Mine area at two locations <br /> in Vindicator Valley (VIN-2A and VIN-2B) and five locations in Grassy Valley (GVMW- <br /> 8A, GVMW-8B, GVMW-22A, and GVMW-22B); downgradient of the North Cresson <br /> Mine area in Poverty Gulch at one location (PGMW-2); and downgradient of the <br /> External Storage Pond ("ESP') in Arequa Gulch (ESPMW-1). A list of wells, <br /> parameters analyzed, and results are presented in Appendix 2, Volume II of this <br /> Amendment 11 documentation. Groundwater may not be encountered in some wells <br /> completed to within a few hundred feet of the surface. In these cases, monitoring will be <br /> limited to checking water levels (i.e., checking for the presence of water) and samples <br /> will not be analyzed unless sufficient water is encountered to allow sampling and <br /> analysis of non-turbid water. " <br /> Table 11-2 in Section 11.2 of the groundwater monitoring plan states that all DRMS groundwater <br /> monitoring locations listed within the table are to be sampled on a quarterly basis. <br /> CC&V's review of the monitoring locations identified within the monitoring plan confirms that CC&V is <br /> monitoring the appropriate locations for groundwater quality. Figure 2 presents the Amendment 11 <br /> compliance groundwater monitoring locations identified within the monitoring plan. <br /> 5 <br />
