CISEC REVIEW TIPS QUESTIONS AND ANSWERS
SURE A+
✔✔Sediment Containment Systems (SCS) - Purpose
Types of drainage methods - ✔✔to contain runoff long enough for deposition of the
suspended particles
must properly trap and contain waters and embakements must be stabilized against
erosion
Types of draining methods:
1. Filter bag
- needs replacement when full
- inspect for tears, connection leaks
2. Riser pipe outlet structure - pipe must have perforations
- Is size and height of pipe adequate?
- Does 1 to 2 in rock surround pipe?
- Never wrap pipe w fabric, will clog
3. Skimmer outlet = EPA Reccommended / most effective
- Is the vent pipe on the top? (Keep screen clean)
✔✔Types of Stabilized Construction Entrances - TC 1's - ✔✔1. Vehicular Tracking Pads
- Rock size 2-4in no larger than 6in
- Is rock dissappearing/ need to be turned over?
2. Grates or Ridges (Pods?)
- Is there sufficient length of pad?
- Is it clean?
- Does a rock pad exist at end?
, 3. Wheel washing
- Is the water properly contained?
- Do polluted waters discharge/leak from the system?
✔✔Flocculant Treatment System Types - ✔✔1. Liquid Treatment System - water
pumped from SCS and mixed w flocculant in a treatment chamber then sent to a
capture system where treated water can be discharged
2. Solid Treatment System - runoff dissolves o soild flocculant "block"
-may or may not have a treatment chamber
✔✔Diversion Channel and Berms - ✔✔an E.C. method used to direct runoff to a specific
location
Inspection:
- Will runoff remain within the diversion channel?
- Are the embankements stabilized?
- Is the discharge area stabilized?
✔✔Slope Drains - ✔✔an E.C. product
Inspection:
- Is the pipe diameter correct?
- Is there an adequate method to CAPTURE that runoff into the pipe?
- Is the pipe properly held in place? (to avoid slipping)
- Ensure that proper connections between pipes exist and there are no leaks
- Does a proper discharge methid exist? (Into a riprap channel? Into a SCS?)
✔✔Establishing Vegetation - ✔✔#1 method for E.C.
- Delineate area carefully!
1. Vegetative Buffer Strip: used to delineate areas of no construction and sensitive
areas. Also traps sediment in runoff waters.
2. Installing SOD: Instant erosion control, but requires moisture and proper installation.
✔✔Seeding - ✔✔Save the removed topsoil for reapplication later when seeding!
Inspection:
- Was the hillside "catwalked" / tracked UP AND DOWN (not along the hillside)
- Was the soil scarified (grooves/raked) for seeding?
- Is fertilizer required? Organic vs Synthetic
✔✔Inspecting Hydraulic Mulch - ✔✔- Do 'shadows' exist?
