A storm drain inlet is protected with a gravel bag barrier. After a storm,
water is ponding several inches deep upstream of the inlet and beginning
to flood an adjacent travel lane. What should the inspector recommend
first?
A. Remove all inlet protection permanently
B. Modify or maintain the inlet protection to restore adequate drainage
while retaining sediment control
C. Ignore the ponding because sediment is being captured
D. Replace the inlet with a larger storm drain - Correct Answer - B
Inlet protection must balance sediment capture with safe drainage.
Excessive ponding that creates a hazard requires maintenance or
modification.
A newly graded 3:1 slope was hydroseeded two weeks ago. An
inspection reveals several rills forming on the slope, sparse germination,
and exposed soil throughout much of the area. Which BMP adjustment
is most appropriate?
A. Remove all seed and leave the slope bare
B. Install erosion control blankets and repair eroded areas
C. Add only additional fertilizer
D. Wait until vegetation reaches 100% cover - Correct Answer - B
,2|Page
Active erosion indicates that temporary stabilization is inadequate.
Erosion control blankets can provide immediate protection while
vegetation establishes.
A sediment basin designed for a large disturbed drainage area is nearly
half-filled with sediment. The outlet structure remains functional, but the
available storage volume has been significantly reduced. What is the
inspector’s best recommendation?
A. Leave the basin unchanged until it completely fills
B. Breach the basin and rely on downstream controls
C. Remove accumulated sediment to restore design capacity
D. Convert the basin into a permanent pond immediately - Correct
Answer - C
Sediment basins require periodic cleanout to maintain storage volume
and treatment effectiveness.
During a site inspection, workers are washing concrete equipment
directly onto bare soil near a drainage swale. No designated washout
area is present. What is the primary compliance concern?
A. Dust generation
B. Excessive vehicle traffic
C. Improper concrete washout and potential discharge of high-pH waste
D. Lack of fertilizer management - Correct Answer - C
Concrete washout water is highly alkaline and must be contained in a
designated washout area.

A large soil stockpile is located adjacent to a storm drain inlet. No
perimeter controls or cover are installed, and rain is forecast within 24
hours. Which action should be recommended immediately?
A. Move the inlet
B. Install perimeter sediment controls and cover or stabilize the stockpile
C. Wait until after the rain event
D. Add fertilizer to the stockpile - Correct Answer: B
Unprotected stockpiles near drainage features are a major sediment
source and should be controlled before rainfall.
Rock check dams have been installed in a temporary drainage swale.
The dams are spaced so far apart that water accelerates between them
and erodes the channel bed. What is the most appropriate corrective
action?
A. Remove all check dams
B. Increase spacing between dams
C. Reconfigure the check dams with proper spacing and elevation
control
D. Replace the swale with a pipe immediately - Correct Answer: C
Check dams must be spaced so the crest of the downstream dam is
approximately level with the toe of the upstream dam, reducing flow
velocity.
Strong winds are carrying dust from a large disturbed area across
adjacent properties and roadways. No dust-control measures are being
implemented. Which BMP category is most appropriate?
A. Dust suppression measures such as watering or soil stabilization
B. Inlet protection
, 4|Page
C. Sediment basin cleanout
D. Riprap outlet protection - Correct Answer - A
Dust control is a pollution-prevention measure commonly addressed
through watering, mulch, or other stabilization methods.
A storm sewer outfall discharges onto an unprotected slope. The
discharge area shows scour holes and exposed subsoil. What BMP is
most likely needed?
A. Additional fertilizer
B. Riprap or other outlet protection to dissipate energy
C. Removal of the storm sewer
D. More inlet protection upstream - Correct Answer - B
Scour at an outfall indicates excessive discharge energy that should be
dissipated with appropriate outlet protection.
During a routine inspection, you identify several BMP deficiencies. The
superintendent agrees to make repairs within 48 hours. What
documentation practice is most appropriate?
A. Document the deficiencies, required corrective actions, and expected
completion timeframe
B. Skip documentation because repairs are promised
C. Record only photographs without notes
D. Wait until the next inspection to document the issues - Correct
Answer - A
Inspection reports should clearly document observations, corrective
actions, responsible parties if applicable, and timelines.
