Spill monitoring will be implemented following clean up. <br />Surface water monitoring will be implemented downstream, if necessary. Soil along the spill <br />pathway will be monitored and decontaminated and/or removed from the site of the spill as <br />necessary. If there is a potential for the spill to migrate off -site, samples may be obtained <br />immediately from downgradient, existing surface and ground water location and any additional <br />water monitoring locations deemed appropriate to monitor the potential migration pathways. <br />The spilled material also may be tested to evaluate the effectiveness of mitigation. <br />11.2 Ground Water <br />Ground water quality and depth to ground water will be monitored on a quarterly basis under <br />MLE2 at the following locations: downgradient of the AGVLF in Arequa Gulch (CRMW -3A <br />and 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 in <br />Vindicator Valley (VIN -2A and VIN -2B) and five locations in Grassy Valley (GVMW -8A, <br />GVMW -8B, GVMW -16, GVMW -24A, and GVMW -24B); downgradient of the North Cresson <br />Mine area in Poverty Gulch at one location (PGMW -2); and downgradient of the External <br />Storage Pond ( "ESP ") in Arequa Gulch (ESPMW -1). <br />These wells, shown in Table 11 -2 and on Figure 11 -1, will be sampled and analyzed for the <br />parameters listed in Table 11 -4. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />11 -2 <br />
