Question 1
The 1970s law that set into place the regulation of stormwater is:
A) The Clean Air Act.
B) The Resource Conservation and Recovery Act.
C) The Clean Water Act.
D) The Safe Drinking Water Act.
E) The Endangered Species Act.
Correct Answer: C) The Clean Water Act
Rationale: The Clean Water Act, enacted in the 1970s, established the
framework for regulating discharges of pollutants into U.S. waters,
including stormwater.
Question 2
Requirements for managing stormwater activity on a construction site are
outlined in the following regulation:
A) OSHA.
B) RCRA.
C) NPDES.
D) CERCLA.
E) EPA.
Correct Answer: C) NPDES
Rationale: The National Pollutant Discharge Elimination System
(NPDES) is a permit program under the Clean Water Act that
regulates discharges into U.S. waters, including stormwater runoff
from construction sites.
Question 3
Which of the following is never an allowable stormwater discharge from a
construction site?
A) Discharge from uncontaminated groundwater.
B) Discharge from routine external building washing.
,C) Discharge from hydrostatic testing.
D) Discharge from contaminated groundwater.
E) Discharge from foundation dewatering.
Correct Answer: D) Discharge from contaminated groundwater
Rationale: Discharge from contaminated groundwater is never an
allowable stormwater discharge from a construction site, as it
contains pollutants that must be treated or managed appropriately.
Question 4
The Notice of Termination (NOT) can be filed when:
A) Construction activity has begun.
B) The SWPPP (Stormwater Pollution Prevention Plan) has been prepared.
C) All construction activity, inside and outside the building, is complete and
permanent stabilization verified.
D) Temporary stabilization is implemented.
E) An inspection is performed.
Correct Answer: C) All construction activity, inside and outside the
building, is complete and permanent stabilization verified
Rationale: The Notice of Termination (NOT) can be filed when all
construction activity, inside and outside the building, is complete
and permanent stabilization of the site has been verified.
Question 5
Relative to stormwater permitting, all of the following must occur before
construction starts EXCEPT:
A) Submit the Notice of Intent (NOI).
B) Prepare the SWPPP.
C) Install initial erosion controls.
D) Submit the Notice of Termination (NOT).
E) Conduct a site assessment.
Correct Answer: D) Submit the notice of termination (NOT)
Rationale: The Notice of Termination (NOT) is
,submitted after construction is complete and the site is stabilized,
not before construction starts.
Question 6
Which erosion control best management practice (BMP) increases water
infiltration, dissipates rainfall energy, and slows overland flow of stormwater?
A) Silt fence.
B) Check dam.
C) Sediment basin.
D) Vegetation.
E) Construction exit.
Correct Answer: D) Vegetation
Rationale: Vegetation (e.g., seeding, sodding) is a highly effective
erosion control BMP that stabilizes soil, increases infiltration, and
slows runoff.
Question 7
Of the following factors that influence erosion rates, the one a contractor has
the MOST control over is:
A) Rainfall intensity.
B) Soil type.
C) Groundcover.
D) Slope length.
E) Wind speed.
Correct Answer: C) Groundcover
Rationale: A contractor has the most control over groundcover, as
they can implement various BMPs like vegetation, mulching, or
erosion control blankets to protect the soil surface.
Question 8
Temporary stabilization should be implemented:
A) Only after permanent structures are built.
B) Only if the site will be inactive for more than 30 days.
, C) Immediately on all disturbed areas that are likely to or will remain inactive
for 14-days or more.
D) Only in areas with steep slopes.
E) Only during the rainy season.
Correct Answer: C) Immediately on all disturbed areas that are likely
to or will remain inactive for 14-days or more
Rationale: Temporary stabilization measures (e.g., seeding, mulching)
should be implemented immediately on all disturbed areas that are
likely to or will remain inactive for 14 days or more to prevent
erosion.
Question 9
The primary purpose of a construction exit is:
A) To manage pedestrian traffic.
B) To provide a secure entry point.
C) To remove sediment from construction site vehicles and minimize
trackout.
D) To store construction materials.
E) To control dust generation.
Correct Answer: C) To remove sediment from construction site vehicles
and minimize trackout
Rationale: A construction exit (stabilized construction entrance/exit)
is primarily designed to minimize the tracking of sediment off-site
by vehicles.
Question 10
Common types of erosion include all of the following EXCEPT:
A) Sheet erosion.
B) Rill erosion.
C) Gully erosion.
D) Wind erosion.
E) Sedimentation.
