sediment poles located in the pond minus the design depth. The percent of sediment <br />buildup is 56% (3' deep divided by 5.3' maximum 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 />Pond 13 collects run-off from the reclaimed north portal. The pond was dry during the <br />inspection. Volume V, Appendix 14-6, page 14-6-58 and 60 show that its design water <br />and sediment capacities are 0.80 A-F and 0.31 A-F respectively. There is little if any <br />sediment build up in the pond. Therefore, the pond's capacity is obtained from the most <br />recent pond certification performed by James E. Stover on August 29, 2002. <br /> Water Sediment Total <br />Pond 13 A-F 0.80 0.34 1.14 <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 />The north decline east and west sumps are designed to contain the 25-year 24 hour <br />storm event without discharge. The sumps were dry during the inspection. The sumps <br />were certified by Larry M. Reschke, P.E. on December 21, 1992. Based on visual <br />observations during the inspection and a hand level survey of the depth of the sumps, <br />the sumps have excess capacity plus the following design capacity: <br />-3- <br />
