Based on the site conditions, <br />l_ reclamation measures are needed to address: <br />• Eagle Park Reservoir - The reservoir contains approximately 1.0 million cubic <br />0; <br />yards of oxide tailing and poor quality water. The reservoir will need to be <br />reclaimed to restore water quality and to provide fresh water storage. In addition, <br />measures will need to be taken to protect the reservoir water quality from upstream <br />sources of poor quality water; <br />Robinson Lake - The lake contains over 1.4 mcy -of unknown quality sludges. <br />Water within the lake is likely to be of poor quality. The lake will need to be <br />reclaimed if it is to be used as future freshwater storage; <br />• No. 1 Tailing Dam seeps - Poor quality seep water directly discharges into <br />Robinson Lake. Reclamation measures will need to be taken to mitigate <br />downstream impact by the poor quality seep water; and <br />• Surface water runoff control - Surface water runoff from the No. 1 Tailing Dam <br />may transport suspended tailing material downstream, thus impacting the <br />overall reclamation of the ERV. <br />Reclamation measures for the ERV were evaluated based on the following criteria: <br />• Compatibility with the current site conditions, <br />• Ability to successfully meet the reclamation objectives for the site, and <br />• Cost-effectiveness and proven field performance. <br />Potential reclamation measures were evaluated using the aforementioned criteria to develop a set <br />of measures that would be applicable to the ERV. Each reclamation measure for the ERV was <br />evaluated as a stand-alone "module." This approach was taken to allow Climax to tailor the <br />reclamation of the valley by "packaging" reclamation measures to suite its specific desires and <br />budgetary constraints. <br />11 <br />c <br />G <br /> <br />3.1 Reclamation Measures Selection <br />This section presents a detailed discussion on the applicable reclamation measures for the ERV. <br />The measures presented are based on the available site data used to define current conditions. A <br />final selection of reclamation measures for the ERV may require collection of additional site data. <br />e _-w Environmental <br />?J <br />• <br />u
