1. What is the primary purpose of a Construction Stormwater Pollution
Prevention Plan (SWPPP)?
A. Establish construction payroll procedures
B. Identify potential stormwater pollutants and establish controls to reduce their
discharge
C. Replace all construction drawings
D. Determine the project's final construction cost
Correct Answer: B. Identify potential stormwater pollutants and establish
controls to reduce their discharge
Rationale: A SWPPP identifies potential sources of stormwater pollution and
specifies control measures to prevent or minimize pollutant discharges. It serves as
a central document for implementing stormwater requirements during
construction.
2. Which federal law provides the primary statutory framework for the NPDES
stormwater permitting program?
A. Clean Air Act
B. Resource Conservation and Recovery Act
C. Clean Water Act
D. Endangered Species Act
Correct Answer: C. Clean Water Act
,Rationale: The Clean Water Act established the federal framework for regulating
pollutant discharges to waters of the United States, including the NPDES permit
program. Construction stormwater permits operate within this framework.
3. What does NPDES stand for?
A. National Pollution Discharge Elimination System
B. National Pollutant Discharge Elimination System
C. National Prevention of Drainage Erosion System
D. National Permit Development and Enforcement Standard
Correct Answer: B. National Pollutant Discharge Elimination System
Rationale: NPDES is the National Pollutant Discharge Elimination System, the
federal permitting framework used to regulate point-source discharges of
pollutants to waters of the United States.
4. Under the California Construction General Permit framework, what is the
primary role of a Qualified SWPPP Practitioner (QSP)?
A. Prepare all project architectural drawings
B. Implement and oversee SWPPP-related requirements during construction
C. Approve building permits
D. Replace the legally responsible person
Correct Answer: B. Implement and oversee SWPPP-related requirements during
construction
Rationale: The QSP is responsible for implementing applicable SWPPP
requirements in the field, including BMP implementation, inspections, monitoring,
and related compliance activities. The QSP does not replace the legally responsible
person.
5. Which role is primarily associated with developing the Construction SWPPP
under the California CGP?
,A. Qualified SWPPP Developer
B. Construction equipment operator
C. Site security officer
D. Materials supplier
Correct Answer: A. Qualified SWPPP Developer
Rationale: The Qualified SWPPP Developer (QSD) is the qualified professional
responsible for developing the project-specific SWPPP and associated technical
components required by the permit.
6. What is the main purpose of a Best Management Practice (BMP)?
A. Increase pollutant discharge
B. Control or reduce stormwater pollution
C. Increase soil disturbance
D. Eliminate construction inspections
Correct Answer: B. Control or reduce stormwater pollution
Rationale: BMPs are practices, procedures, or structural measures used to
prevent, reduce, or control pollutants in stormwater discharges. They may address
erosion, sediment, materials, runoff, or other pollutant sources.
7. Which process describes the detachment and transport of soil particles?
A. Sedimentation
B. Infiltration
C. Erosion
D. Filtration
Correct Answer: C. Erosion
Rationale: Erosion involves the detachment and movement of soil particles by
water, wind, or other forces. Sediment-control measures address soil after it has
become mobile.
, 8. What is sedimentation?
A. The settling or deposition of transported particles
B. The detachment of soil by rainfall
C. The infiltration of water into soil
D. The evaporation of stormwater
Correct Answer: A. The settling or deposition of transported particles
Rationale: Sedimentation occurs when suspended or transported particles settle
out of moving water. Sediment basins and traps use detention and reduced flow
velocity to promote this process.
9. Which condition generally creates the greatest potential for construction-site
erosion?
A. Dense established vegetation
B. Fully stabilized soil
C. Exposed disturbed soil
D. Completed pavement
Correct Answer: C. Exposed disturbed soil
Rationale: Disturbed soil without protective cover is highly vulnerable to rainfall
and runoff. Minimizing exposed soil and stabilizing disturbed areas are important
erosion-prevention strategies.
10. Why is temporary stabilization used on a construction site?
A. To protect exposed soil until permanent stabilization is established
B. To increase runoff velocity
C. To eliminate all stormwater monitoring
D. To increase the amount of disturbed soil
Correct Answer: A. To protect exposed soil until permanent stabilization is
established
