1. What is the primary goal of stormwater management on
construction sites?
A. Increase groundwater levels
B. Prevent erosion and control pollutant discharge
C. Speed up construction activities
D. Eliminate all rainfall runoff
Correct answer: B
Rationale: Stormwater management focuses on reducing
erosion, sediment transport, and pollutant discharge from
disturbed sites into waterways.
2. Which federal law regulates stormwater discharges in the
United States?
A. Clean Air Act
B. Safe Drinking Water Act
C. Clean Water Act
D. Resource Conservation and Recovery Act
Correct answer: C
,Rationale: The Clean Water Act regulates pollutant discharges
into U.S. waters, including stormwater through the NPDES
program.
3. What does BMP stand for in stormwater management?
A. Best Management Practices
B. Basic Maintenance Procedures
C. Bulk Material Protection
D. Biological Monitoring Plan
Correct answer: A
Rationale: BMPs are practices or controls used to reduce
pollution and manage stormwater runoff effectively.
4. Which of the following is an example of a structural BMP?
A. Employee training
B. Silt fence installation
C. Spill prevention plan
D. Material storage policy
Correct answer: B
Rationale: Structural BMPs are physical devices or installations
such as silt fences, sediment basins, or check dams.
5. What is erosion?
,A. Movement of sediment by wind, water, or gravity
B. Chemical breakdown of rocks
C. Water infiltration into soil
D. Plant growth on soil
Correct answer: A
Rationale: Erosion is the physical removal and transport of soil
particles by natural forces.
6. What is the purpose of a Stormwater Pollution Prevention
Plan (SWPPP)?
A. Increase construction speed
B. Identify and control pollutant sources on a site
C. Design building foundations
D. Manage labor schedules
Correct answer: B
Rationale: A SWPPP outlines how a site will prevent
stormwater contamination during construction.
7. Which BMP helps stabilize soil temporarily?
A. Concrete pavement
B. Mulching
C. Steel reinforcement
D. Asphalt paving
, Correct answer: B
Rationale: Mulching protects exposed soil from rainfall impact
and reduces erosion.
8. What is sediment?
A. Dissolved chemicals in water
B. Solid particles transported by water or wind
C. Clean sand used in construction
D. Organic plant material only
Correct answer: B
Rationale: Sediment consists of soil particles carried by runoff
or wind.
9. What is the purpose of a silt fence?
A. Filter air pollutants
B. Trap sediment while allowing water flow
C. Strengthen excavation walls
D. Increase water pressure
Correct answer: B
Rationale: Silt fences slow runoff and trap sediment on
construction sites.
10. What is non-point source pollution?
