J' <br />feet of available storage. Figure 3, HG-8 Cross-Section, displays the discharge structure <br />configuration and shows the corresponding water surface elevations. In addition, the SEDCAD <br />modeling indicates that 2.70 acre-feet of storage is required to retain runoff from the 10-year, 24-hour <br />storm event. Figure 4, Pond HG-8 StagelStorage Curve, displays stage and the corresponding <br />storage for pond HG-8 which indicate that the pond capacity will be sufficient to contain the storm <br />run-off. The methodology and assumptions used in calculating runoff are included in Attachment 1. <br />Results ofthe SEDCAD modeling can be found in Attachment 2. The SEDCAD modeling indicates <br />that the retention time for the storm event inflows is in excess of seven days which will allow pond <br />storm event inflows to meet effluent limitations for settleable solids prior to being discharged into <br />receiving waters. <br />~:~s~~es~muym~x~nu~vs 7/16/96 2 <br />
