• <br />The CERP also includes procedures for contacting the media, as well as <br />downstream water users if the watershed below the VLF (Arequa Gulch) were to <br />be impacted. <br />7.5 Incorporate into response plans monitoring elements and <br />remediation measures that account for the additional hazards of <br />using cyanide treatment chemicals. <br />The operation is: ^ in full compliance <br />^ in substantial compliance <br />Drinking water supply wells are a considerable distance from the site, and are <br />highly unlikely to be affected by any spills. The Cities of Victor and Cripple <br />Creek are on a municipal water supply with a reservoir source upgradient of the <br />mine site. CC&V uses only bottled water; there is no other potable water supply. <br />Describe the basis for the Finding/Deficiencies Identified: <br />• <br />• <br />The potential for a cyanide spill to the ground surface outside the containment <br />area is low as the ADR and VLF are all underlain by an engineered liner system. <br />If a spill did occur off-liner, contaminated soil. material from spill cleanup is <br />required to be placed on the VLF heap. Spilled solutions and carbon granules <br />within the ADR are recycled back into the process. <br />The CERP specifies actions to be taken to respond to a spill and requires soil <br />neutralization using sodium hypochlorite solution and over-excavation of the <br />spill area to ensure all impacted material, including neutralized material, is <br />removed. Cyanide SOPs implemented in the ADR also details procedures for <br />clean up of a plant-site cyanide spill. The Spill Prevention, Control and <br />Countermeasure (SPCC) Plan also provides general guidance for collection and <br />analysis of soil samples. <br />^ not in compliance ...with Standard of Practice 7.5. <br />In the event of a spill to surface water (i.e., a hypothetical release to Arequa <br />Gulch) samples would be collected at established downstream locations as close <br />to the point of entry as possible. Methods for collection and analyzing samples <br />to confirm cleanup of spills are provided in the SPCC Plan.
