• <br />• <br />• A conservative 100-year, 24-hour design storm was used in design and <br />permitting (3.65 inches) plus a 12-hour power outage instantaneous drain- <br />down situation. <br />• Reliable precipitation and evaporation data are provided by the <br />meteorological monitoring stations. <br />• Precipitation entering the pond is tracked in gpm for the six VLF <br />subdivisions. <br />• Freezing and thawing conditions require seasonal discontinuation of <br />sidehill leaching, but have otherwise not interrupted the normal leach <br />cycle. <br />• Solution losses other than evaporation are limited, due to close oversight <br />and maintenance, and the operation of solution collection and pumpback <br />systems at all major collection points. <br />• Power outages and their effects on the water balance are effectively <br />mitigated by the availability of the emergency diesel generating system. <br />• Heap dynamics are also considered in the model, including delivered ore <br />moisture, surface area, and saturation capacity. <br />The model also considers local climatological data, which are collected from <br />multifunction meteorological stations and wind speed monitors at the mine site. <br />The multifunction stations collect data year round, including wind speed and <br />direction, wind direction, temperature, barometric pressure, and precipitation. <br />4.4 Implement measures to protect birds, other wildlife and livestock <br />from adverse effects of cyanide process solutions. <br />The operation is: ^ in full compliance <br />^ in substantial compliance <br />^ not incompliance ...with Standard of Practice 4.4. <br />Discuss the basis for the Finding/Deficiencies Identified: <br />• <br />Cresson Proiect <br />Name of Mine <br />/'" <br />~~~r~ ~ <br />Signature of Lead Auditor <br />10 September 2007 <br />Date <br />Page 15 of 41 <br />
