Pump discharge shall be discharged into a settling pond or onto an area suitable to filter the sediment from the discharge prior to entering a stream or body of water as directed by the C.O.R.

D. Dredging Requirements. Prior to the beginning of excavation all necessary clearing along the pond edge and dewatering shall be completed.

The pond shall be excavated to the depth and slopes shown on Sheet 19 and with a horizontal bottom. The excavation shall be carried to either the specified depth or solid rock whichever occurs first. Excavation of solid rock is not required. If a permeable material is encountered in the excavation that will cause the pond to leak, all excavation shall cease and the COR shall be notified immediately.

Excavated surfaces shall be reasonably smooth and uniform around the pond perimeter. All existing depressions, sloughs and washed or worn depressions on the external dike side slope surface and on all internal pond perimeter side slope surfaces shall be filled with excavated material to provide a uniform surface from the existing ground surface to the pond bottom. Transitions between different side slopes shall be uniform over the distance specified on the drawings.

E. Silt Fence Used For Erosion Control. A silt fence shall be used in the construction of temporary structures such as settling basins, check dams and other application as determined by the C.O.R. to control erosion and contain soil runoff. Silt fence shall be constructed in accordance with manufactures specifications.

F. Cleanup and Disposal. All excavated material shall be disposed of at the on site location(s) shown on the drawings or at other on site locations directed by the C.O.R. Excavated material shall be placed and spread so that it shall blend in with the existing natural or man-made landforms at the disposal site. It is not the intent to create mounds or piles of waste material. The surface of the disposed material shall be sloped to drain, graded smooth and uniform with no projecting rocks, roots, stumps or other debris and be suitable for field mowing. Machine back blading is acceptable for the finished surface.

When disposed material is to wet to shape properly, it will be left to drain until it becomes suitable to grade and shaped as required above.

All cut brush and trees and slash shall be removed and buried in the waste disposal area shown on the drawings or at other locations as directed by the C.O.R. All waste materials shall be matted down in layer and covered with at least two (2) feet of material dredged from the pond.
