EMERGENCY SPILLWAY <br />I. Is the overall emergency spillway system of currently capable of passing the design storm discharge? Yes <br />No <br />The capacities of the spillways were not checked. The spillways are in good condition. <br />2. Does it appear as if the emergeny spillways have discharged water since the last inspection? Yes <br />No X . <br />3. Ls erosion occurring at any section of the emergency spillways? Yes _ No X . Describe extent and <br />location• None. <br />SEDIMENT STORAGE CAPACITY <br />1. Has the design sediment storage capacity of the reservoir been surpassed? Yes _ No _ If yes, <br />explain. <br />Water in the ponds obscured any sedimen[ that may have been in the ponds. A cursory review of Permit <br />documentation available found no design sedimentation volume for the current pond. <br />OTHER OBSERVATIONS: <br />1. Indications of potential failure or instability: None. There were no indications of slumps, slides, cracks, <br />or differential settlement on the embankments (upslope or downslope). <br />2. There were no indications of rodent activity on the embankments (upslope or downslope). <br />3. Threat to human life or property: slight to none except to the structures [hemselves. Maximum capacity <br />of Pond 002 is approximately 0.8 acre feet. The maximum capacity of Pond 002A is approximately 0.5 acre <br />feet, and approximately 0.9 acre feet for Pond 002B. The region below the structures is a short slope to <br />the ephemral stream, u~th no development. <br />5. Potential harm to land, air, and water resources: Water quality of the Purgatoire River could be affected <br />by a release from one or a combination of the three ponds, not exceeding approximately 2.5 acre feet of <br />mine water discharge, for a short period of time should the pond embankments fail. <br />MAINTENANCE REQUIRED <br />1.
