Storage Capacity <br /> The storage capacity of Sediment Pond 005 was also analyzed using the <br /> SEDIMOT II computer program. Table 6 is a summary of the designed <br /> storage capacity. <br /> TABLE 6 <br /> Design Storage Capacity Summary <br /> Sediment Pond 005 <br /> Stage Capacity <br /> Elevation (Feet) (Ac-ft) Description <br /> 5690.0 0.0 0.00 Bottom of Pond <br /> 5694.0 4.0 0.42 Elevation of Principal <br /> Spillway and 100% <br /> Sediment Storage <br /> 5699.04 9.04 1.50 10-year, 24-hour Peak <br /> Stage <br /> 5700.06 10.06 1.82 25-year, 24-hour Peak <br /> Stage <br /> 5701.0 11.0 2.20 Elevation of Emergency <br /> Spillway <br /> 5702.53 12.53 2.94 100-year, 24-hour Peak <br /> Stage <br /> 5703.0 13.0 3.19 Elevation of the Top <br /> of the Embankment <br /> Peabody does not anticipate any pit pumpage or other inflow to the pond <br /> at this time. <br /> SPILLWAY <br /> Sediment Pond 005 provides for a combination of principal-emergency <br /> spillway to safely discharge the runoff from a 25-year, 24-hour storm. <br /> The principal spillway inlet will also be used as the nonclogging <br /> dewatering device and is located at an elevation higher than the maximum <br /> sediment storage volume. The principal spillway inlet is located in a <br /> position on the embankment so as to prevent short-circuiting as much as <br /> 9 <br />
