to the emergency spillway, which is at that same elevation. The <br />• spillway is not approximately 20 feet from the top of the embankment but <br />has been constructed through the embankment to ensure that high Tevei <br />flows of water are routed in a controlled manner from the sediment pond <br />to the existing receiving waters channel. <br />17. What ha ens to flows once the exit the emer enc s illwa ? How <br />wi t ey be channe ize to t e existing drainage? <br />RESPONSE: <br />As part of the emergency spillway, a channel has been constructed to the <br />receiving stream channel downstream of the embankment. The emergency <br />spillway has been channelized to hold the design flow and direct it to <br />the existing drainage. <br />18. The principal and emergency spillway locations should be shown on <br />MaP 12. <br />• RESPONSE: <br />The principal and emergency spillway locations are shown on the Mine <br />Facilities Map (Map 12). <br />19.
