1、BCCD STANDARD EROSION AND SEDIMENTATION CONTROL PLAN NOTESGeneral notes1. Only limited disturbance will be permitted to provide access to (construct sediment traps, diversion terraces, etc.) for grading and acquiring borrow to construct those controls. 2. Erosion and sedimentation controls must be c
2、onstructed, stabilized, and functional before site disturbance within the tributary areas of those controls.3. After final site stabilization has been achieved, temporary erosion and sedimentation controls must be removed. Areas disturbed during removal of the controls must be stabilized immediately
3、.4. Vehicles and equipment may neither enter directly to nor exit directly from lot _ onto _. (Insert the lot numbers and road names.)5. At the end of each working day, any sediment tracked or conveyed onto a public roadway will be removed and redeposited onto the construction site. Removal can be c
4、ompleted through use of mechanical or hand tools, but must never be washed off the road by use of water.6. Sediment removed from E&SPC controls & facilities shall be disposed of in landscaped areas outside of steep slopes, wetlands, floodplains or drainage swales and immediately stabilized, or place
5、d in topsoil stockpiles. 7. All pumping of sediment laden water shall be through a dirt bag filtration device, or equivalent sediment removal facility, over non-disturbed vegetated areas. Discharge points should be established to provide for maximum distance to active waterways.8. All excavation for
6、 utility line installation shall be limited to the amount that can be excavated, installed, backfilled and stabilized within one working day. All excavated material shall be deposited on the upslope side of the trench.9. Should unforeseen erosive conditions develop during construction, the contracto
7、r shall take action to remedy such conditions and to prevent damage to adjacent properties as a result of increased runoff and/or sediment displacement. Stockpiles of wood chips, hay bales, crushed stone and other mulches shall be held in readiness to deal immediately with emergency problems of eros
8、ion.10. The contractor is advised to become thoroughly familiar with the provisions of the Appendix 64, Erosion Control Rules and Regulations, Title 25, Part 1, Department of environmental Protection, Subpart C, Protection of Natural Resources, Article III, Water Resources, Chapter 102, Erosion Cont
9、rol.11. A copy of this erosion and sedimentation control report and plans must be posted at the construction site. Sediment Basin Notes (to be included with detail)12. Clean out stakes must be placed at half distances from points of concentrated inflows to temporary risers. When sediment has accumul
10、ated to clean out elevations on any stake, it must be removed to restore basin capacities. 13. Sedimentation basins must be protected from unauthorized acts of third parties. 14. Baffles must be installed to allow basin maintenance and clean-out.15. Approval of the use of a skimmer does not approve
11、owner or operator use of any skimmer in violation of any patent, patent rights and/or patent laws.16. Fill material for the embankments shall be free of roots, or other woody vegetation, organic material, large stones, and other objectionable materials. The embankment shall be compacted in maximum _
12、” layered lifts at _% density.17. Sediment basins shall be kept free of all trash, concrete wash water and other debris that pose the potential for clogging the basin outlet structures and/or pose the potential for pollution to Waters of the Commonwealth.18. A standard note is needed with the clean
13、out marker detail stating, “When sediment has accumulated to the clean out elevation on any stake, all accumulated sediment shall be removed from the entire basin bottom.”Sediment Trap Notes (to be included with detail)19. Sediment must be removed from traps when sediment has accumulated to the clea
14、n out elevation.20. Sediment traps must be protected from unauthorized acts of third parties.Channel Notes21. All channels must be kept free of obstructions such as fill ground, fallen leaves & woody debris, accumulated sediment, and construction materials/wastes. Channels should be kept mowed and/o
15、r free of all weedy, brushy or woody growth. Any underground utilities running across/ through the channel(s) shall be immediately backfilled and the channel(s) repaired and stabilized per the channel cross-section detail. 22. Vegetated channels shall be constructed free of rocks, tree roots, stumps
16、 or other projections that will impede normal channel flow and/or prevent good lining to soil contact. The channel shall be initially over-excavated to allow for the placement of topsoil.Filter Fabric Notes (to be included with detail)23. Filter fabric fence must be installed at level grade. Both ends of each fence section must extend at le
