The operation is: <br />Describe the basis for the Finding/Deficiencies Identified: <br />The CERP specifies that all releases of cyanide to the land will be cleaned up as soon as <br />practicable. The plan stipulates using calcium hypochlorite solution to neutralize the <br />cyanide and to over - excavate the spill area to ensure all impacted material is removed. It <br />includes precautions to prevent the generation and exposure to cyanogen chloride gas. <br />Methods for collection and analysis of samples and environmental monitoring to confirm <br />completion of cleanup are provided in the Spill Response Plan that forms part of the ERP. <br />In the event that a spill of cyanide solution outside the lined area of cyanide- containment, <br />the CERP specifies that soil material generated during spill cleanup would be placed on <br />the VLF. Spilled solutions and carbon granules in the mill would be recycled back in the <br />process. Solid cyanide from spilt briquettes will be shoved or swept up and returned to <br />the ADR process stream, cyanide area, or VLF. <br />Drinking water supply wells are a considerable distance from the site, and are highly <br />unlikely to be affected by spills. Victor and Cripple Creek are on municipal water supply <br />from reservoir sources. CC &V uses bottled water. There is therefore no provision <br />needed for an alternate drinking water source. In the event of a spill to Arequa Gulch <br />samples of the released solution would be collected if possible, at established locations, <br />and downstream as close to the point of entry. The CERP prohibits attempts to oxidize, <br />neutralize or otherwise treat cyanide once it has entered surface water. <br />7.6 Periodically evaluate response procedures and capabilities and revise <br />them as needed. <br />The operation is: <br />Describe the basis for the Finding/Deficiencies Identified: <br />Cresson Project <br />Name of Mine <br />7.5 Incorporate into response plans monitoring elements and remediation <br />measures that account for the additional hazards of using cyanide <br />treatment chemicals. <br />• in full compliance <br />❑ in substantial compliance <br />❑ not in compliance...with Standard of Practice 7.5. <br />• in full compliance <br />❑ in substantial compliance <br />❑ not in compliance...with Standard of Practice 7.6. <br />September 22, 2010 <br />Signature of Lead Auditor Date <br />Page 31 of 36 <br />
