Item | Corrective Action Required if | Corrective Action |
---|---|---|
Silt fence | Wrong type installed
Installed in wrong location Improper geotextile used Insufficient geotextile embedment or weighting units Insufficient compaction of soil Soil turned over, loosened, or both due to inadequate equipment for sliced type Inadequate fastenings Incorrect post spacing Inadequate intra-fence end-joint connections Improperly wrapped under J-barrier Silt fence left in place when no longer needed Turbidity barrier missing top interconnect cable Silt fence type not maintained for function or performance |
Remove and install as shown in plan
Remove silt fence Replace with correct geotextile Reinstall silt fence or apply sandbags or aggregate toe mass Compact soil with tire or plate compactor Compact soil with tire or plate compactor Install more zip-ties Install more posts Wrap geotextiles around post to provide seal; else fill gap Reinstall J-barrier Immediately remove silt fence Install interconnect cable Immediately fix the problem |
Bale barriers | Not notched in
Not properly staked into the ground Not properly overlain with RECP |
Remove bales and subcut a notch
Add stakes of sufficient length Install blanket and anchors |
Filter berms | Damaged or compacted by equipment
Berm breached or bypassed Improper depth to width ratio Rock weeper missing filter aggregate face |
Restore filtration function by soil loosening
Add fill, embed rock buttress, reconfigure drainage Add more fill to conform to berm detail Add coarse filter aggregate front side of flow |
Floating silt curtain | Curtain not end anchored on land or adjacent perimeter control
Curtain not weighted sufficiently in water or for field conditions Improper depth(s) Improper in-water anchoring/tethering Curtain left in water beyond temporary in-water work phase Curtain too far from land edge Navigation buoys not installed with flowing water type |
Bring end of curtain onto land or close the gap
Install correct curtain, add anchors and cables Install correct curtain depth for in-water ground contact Remove and install with proper depths Immediately remove and install new controls on land Recover and reinstall following detail of 6 ft maximum Install navigation buoys as necessary |
Perimeter controls | Incorrect BMP for location
Not properly J-hooked at termination points Not placed along contours when feasible Wrong type installed for intended application Not maintained for function No redundant practice above water resource |
Remove and install proper perimeter control
Remove section, install J-hook section and connect upgradient Reconfigure control to match slope contour Remove and install proper control Immediately apply maintenance to restore function Add control redundancy |
Sediment control logs | Not staked properly resulting in undermining or movement of logs
Log ends not overlapped when more than one is needed in a line |
Install additional stakes
Reconfigure logs for overlap |
Sandbag barrier | Sandbags not butt end jointed to provide seal
Sandbags not sufficiently high Sandbags not installed on contour Sandbags not working as a diversion Middle of sandbag dike higher than ends |
Re-install sand bags
Add more sand bags in interlocked pyramid style configuration Re-configure barrier to conform to contour Re-install with a plastic cover wrap Reconfigure placement to lower middle or extend upper ends |
