<br />~ Issues to be considered by the Mined Land Reclamation Board regarding the <br />San Luis Project permit amendment application. <br />1. Design <br />- Adequacy of water augmentation plan; <br />- Routing of flows which exceed probable maximum precipitation event; <br />- Clarification of tailings receiving stream; <br />- Adequacy of 100-year 24-hour design storm event for temporar,~ diversions; <br />- Adequacy of tailings liner system; <br />- Necessity of leak detection system; <br />- Definition of acceptable leakage from tailings facility; <br />- Establishment of appropriate probable maximum precipitation event; <br />- Anticipated tailings permeability; <br />2. Water Quality <br />- Impacts to waterfowl due to free water pool and water retention structure; <br />- Potential for post mining groundwater contamination; <br />- Potential for toxic leakage from Waste Rock Disposal Area D entering <br />Rito Seco; <br />3. General Hydrology <br />- Offsite erosion and sedimentation potential during operations; <br />- Placement of downgradient monitoring wells; <br />4. Air Quality <br />- Dust generation from tailings facility; <br />- Health impacts due to gasseous emissions from the mill facility; <br />5. Geochemistry <br />- Tailings geochemistry; <br />- Long-term leaching of metals from tailings; <br />6. Stability <br />- Impacts to Rito Seco due to earthquake related failures of Waste Rock <br />Disposal Area D and South Waste Rock Disposal Facility; <br />- Consequence of splitter embankment failure; <br />7. Operations <br />- Containment of chemical spills within the mill facility; <br />- Adequacy of leakage reporting and corrective action criteria; <br />- Public access to monitoring data; <br />- Tailings decontamination; <br />- Topsoil losses due to erosion; <br />
