1. What is the primary purpose of a Stormwater Pollution Prevention Plan
(SWPPP)?
A. To establish employee work schedules
B. To document construction costs
C. To identify potential pollutant sources and describe measures to control them
D. To replace all construction permits
Correct Answer: C. To identify potential pollutant sources and describe
measures to control them
Rationale: A SWPPP explains how a construction project will identify potential
sources of stormwater pollution and implement erosion, sediment, and pollution-
prevention controls. It is a central document for demonstrating how permit
requirements will be implemented.
2. When should a SWPPP generally be developed under the federal construction
general permit framework?
A. After construction is completed
B. Before submitting the Notice of Intent (NOI)
C. Only after the first rainfall
D. After final stabilization
Correct Answer: B. Before submitting the Notice of Intent (NOI)
Rationale: EPA's construction general permit requires operators to develop a
SWPPP consistent with the permit requirements before submitting the NOI for
,coverage. The SWPPP provides the framework for implementing required
stormwater controls. (US EPA)
3. What does SWPPP stand for?
A. Stormwater Pollution Prevention Plan
B. Surface Water Protection and Planning Program
C. Stormwater Permit Processing Procedure
D. Soil and Water Pollution Prevention Program
Correct Answer: A. Stormwater Pollution Prevention Plan
Rationale: SWPPP is the standard abbreviation for Stormwater Pollution
Prevention Plan. It is the site-specific planning document used to describe
stormwater pollution-prevention practices and controls.
4. Which construction activity is most likely to increase the potential for
sediment discharge?
A. Interior office painting
B. Clearing and grading soil
C. Installing office furniture
D. Conducting employee training
Correct Answer: B. Clearing and grading soil
Rationale: Clearing removes protective vegetation and grading exposes and
moves soil. These activities increase the amount of soil that can be detached and
transported by stormwater.
5. What is the main pollutant of concern associated with exposed soil at many
construction sites?
A. Sediment
B. Chlorine gas
,C. Refrigerant
D. Compressed air
Correct Answer: A. Sediment
Rationale: Sediment is one of the most common pollutants associated with
construction activities. Rainfall and runoff can detach exposed soil and transport it
to storm drains and receiving waters. (US EPA)
6. Which SWPPP component identifies locations where construction activities
may generate pollutants?
A. Site-specific pollutant source assessment
B. Employee attendance sheet
C. Payroll schedule
D. Equipment warranty
Correct Answer: A. Site-specific pollutant source assessment
Rationale: Identifying pollutant sources is fundamental to SWPPP development.
Sources can include exposed soil, stockpiles, construction materials, equipment
fueling areas, waste storage, and other activities that may interact with
stormwater.
7. Why should a SWPPP include a site map?
A. To display employee parking preferences
B. To show relevant site features, drainage patterns, and stormwater controls
C. To replace all inspection records
D. To calculate construction wages
Correct Answer: B. To show relevant site features, drainage patterns, and
stormwater controls
Rationale: A site map helps users understand drainage patterns, disturbed areas,
discharge points, receiving waters, BMP locations, material-storage areas, and
other features relevant to stormwater management.
, 8. Which feature is particularly important to identify on a construction SWPPP
site map?
A. Employee break-room furniture
B. Stormwater discharge points
C. Office computer locations
D. Contractor advertising signs
Correct Answer: B. Stormwater discharge points
Rationale: Identifying discharge points helps the project understand where
stormwater leaves the site and where controls and inspections may need
particular attention.
9. What is the primary function of an erosion control?
A. Prevent or minimize soil detachment and erosion
B. Increase runoff velocity
C. Transport sediment off site
D. Store construction chemicals
Correct Answer: A. Prevent or minimize soil detachment and erosion
Rationale: Erosion controls address soil loss at its source. Examples include
maintaining vegetation, applying mulch, stabilizing slopes, and using erosion-
control blankets.
10. What is the primary function of a sediment control?
A. Increase soil exposure
B. Capture or retain sediment after it has been mobilized
C. Increase concentrated flow
D. Remove vegetation from slopes
Correct Answer: B. Capture or retain sediment after it has been mobilized
