Sediment control structures such as silt fence most commonly trap sediment by the following
means:
a. Slowing water to allow sediment particles to settle out.
b. Serving as a filter that traps sediment particles in the small openings.
c. Preventing on-site erosion.
d. Serving as obstacles for vehicular traffic to slow movement. - ANS a. Slowing water to
allow sediment particles to settle out.
PAM is a chemical that is added to turbulent runoff primarily to achieve the following:
a. Change the turbulent flow to laminar flow.
b. Cause flocculation that reduces sediment transport.
c. Make the water potable immediately.
d. Provide binding of seed to mulch so that vegetation can be established. - ANS b. Cause
flocculation that reduces sediment transport.

a. ECBs
, b. Mulches
c. Riprap
d. Construction entrance - ANS d. Construction entrance
Filter fabric inlet protection is the most appropriate BMP of choice in situations where the flow
rate is:
a. High (> 0.5 cfs)
b. Medium (~ 0.5 cfs)
c. Low (< 0.5 cfs)
d. Frequent - ANS c. Low (< 0.5 cfs)
Which of the following would not file a Notice of Intent (NOI) prior to any land disturbing
activities?
a. Secondary Permittee
b. Utility Provider

Final site stabilization is achieved when percent vegetative cover on all disturbed areas is at
least the following:
a. 65%
b. 70%
c. 80%
