Pond 9 collects run-off from the South Portal and RSRDA. The pond was dry during <br />the inspection. Volume 111, Appendix 13-2, page RSS-15 shows that its design water <br />and sediment capacities are 0.70 A-F and 0.33 A-F respectively. There are <br />approximately 2.2 feet of sediment buildup in the pond. This figure is derived from the <br />length of the sediment pole minus the design depth. Based on this sediment buildup <br />and aerial topo maps, the pond has the following estimated capacity: <br /> Water Sediment Total <br />Pond 9 - A-F 0.66 0.14 0.70 <br />The actual water capacity of Pond 9 is slightly less than the design capacity. However, <br />since the pile has been partially reclaimed, the available water capacity in pond 9 <br />should be adequate. <br />Pond 10 collects run-off from CRDA-2. The pond was dry during the inspection. <br />Volume III, Appendix 13-2, page CRDA2-1 shows its design water and sediment <br />capacities are 1.37 A-F and 1.23 A-F respectively. There are approximately 3-feet of <br />sediment buildup in the pond. This figure is derived from the average length of the two <br />sediment poles located in the pond minus the design depth. Based on this sediment <br />buildup and aerial topo maps, the pond has the following estimated capacity: <br /> Water Sediment Total <br />Pond 10 A-F 1.48 0.58 2.06 <br />Pond 11 collects run-off from Cameo Borrow Area No 2. The pond was dry during the <br />inspection. Volume III, Appendix 13-2, page CRDA3-2 indicates its design water and <br />sediment capacities are 0.40 A-F and 0.27 A-F respectively for CBA-2 only. This pond <br />was changed substantially during borrow operations at CBA-2 during the first quarter of <br />2002. The embankment on the west end of the pond was opened up to the borrow <br />area. Therefore, the capacity of the pond was expanded to beyond what is necessary <br />for the design event from CBA-2. <br />The CBA-1 sump collects run-off from Cameo Borrow Area No. 1. The sump was dry <br />during the inspection. The sump was certified by Larry M. Reschke, P.E., on <br />September 10, 1994. Based on visual observations during the inspection and a hand <br />level survey of the depth of the sump, CBA-1 sump has the following estimated <br />capacity: <br /> Water Sediment Total <br />CBA-1 Sump A-F 0.22 N/A 0.22 <br />-3- <br />
