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
