Spill <br />monitoring will be implemented following clean up. Surface water monitoring will be <br />• implemented downstream, if necessary. Soil along the spill pathway will be monitored <br />and decontaminated and/or moved as necessary. If there is a potential for the spill to <br />migrate off-site, samples will be obtained expeditiously from down-gradient, existing <br />surface and ground water stations and any additional water monitoring points deemed <br />appropriate to monitor the potential migration pathways. The spilled material also may be <br />tested to evaluate the effectiveness of mitigation. <br />10.2 Ground Water <br />Ground water quality and depth to ground water will be monitored on a quarterly basis <br />under the MLE at the following locations: downgradient of the VLF in Arequa Gulch <br />(CRMW-3A and CRMW-3B); downgradient of the mining operations in Squaw Gulch <br />(SGMW-5); downgradient of the East Cresson Mine area at two locations in Vindicator <br />Valley (VIN-2A and VIN-2B); downgradient of the North Cresson Mine area in Poverty <br />Gulch at one location (PGMW-2); downgradient of the operation in Wilson Creek <br />(WCMW-6); and downgradient of ESP in Arequa Gulch (ESPMW-1). <br />These wells, shown in Table 10-2 and on Figure 10-1, will be sampled and analyzed for <br />the parameters listed in Table 10-4. <br />• Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />10-2
