Robinson Lake Operating Plan Climax Molybdenum Company <br />Version R1 Permit M-1977-493 <br />• Operate the Robinson Lake Pump Station to remove water from Robinson Lake, utilizing <br />the installed spare pump to increase pumping capacity as needed. <br />• Operate Warren's Pump Station to remove water from the Robinson Lake basin into the <br />Tenmile Creek basin. <br />• In the event of a long-term power failure, Climax will mobilize a generator(s) to the Site to <br />power pumps as needed. <br />• In the event of catastrophic failure of one or more of the pump systems, Climax will <br />mobilize portable diesel -powered pumps to the Site to provide adequate pumping <br />capacity. <br />Following any storm event, snowmelt events, and/or combination of such events that has caused <br />the reservoir to exceed operational thresholds, Climax will take action to return the lake level to <br />allow storage of a 10 -year storm event within ten days and to a level at or below the appropriate <br />operating threshold as soon as possible but no later than 30 days from when the threshold is <br />exceeded using all reasonably available measures. If the available onsite pumping capacity is <br />not adequate to return the water level in the lake to below the appropriate upper operating limit <br />following such an occurrence, the necessary equipment and appropriate actions will be employed <br />to return Robinson Lake as described above. No process water will be transferred into Robinson <br />Lake until the water level in the lake is returned to a level at or below the appropriate operational <br />threshold. The water removed from Robinson Lake during such an event will be contained within <br />the Climax process water/water treatment system in the Tenmile Creek basin. <br />8.0 REPORTING <br />An annual report will be prepared that documents the flood storage and release status for the <br />year. Climax will provide a copy of this report to the Eagle Park Reservoir Company and the <br />Clinton Ditch & Reservoir Company concurrently with its provision to the DRMS. <br />EPP — Appendix D December 2011 <br />
