1. Which of the following is the primary purpose of a stormwater
environmental inspector during construction and industrial site
inspections?
A. To design new drainage systems for private developments
B. To enforce compliance with stormwater regulations and prevent pollution
from entering waterways
C. To approve building permits for all construction projects
D. To replace engineers responsible for site planning
Answer: B
A stormwater environmental inspector’s main responsibility is to verify
that sites comply with stormwater management requirements and that
pollutants such as sediment, chemicals, and debris are prevented from
reaching surface waters.
2. Which federal regulation primarily establishes requirements for
controlling stormwater discharges from construction and industrial
activities in the United States?
,A. Clean Air Act
B. Resource Conservation and Recovery Act
C. National Pollutant Discharge Elimination System (NPDES) Program
D. Safe Drinking Water Act
Answer: C
The NPDES program, established under the Clean Water Act, regulates
stormwater discharges and requires permits and pollution prevention
measures for certain activities.
3. During a stormwater inspection, what is the inspector’s first priority
upon arriving at a construction site?
A. Collecting fines immediately
B. Reviewing site conditions and identifying potential pollution sources
C. Interviewing all construction workers
D. Measuring the height of all structures
Answer: B
Inspectors must first evaluate site conditions, observe potential pollutant
sources, and understand site activities before determining compliance
status.
4. What is the main purpose of a Stormwater Pollution Prevention Plan
(SWPPP)?
A. To provide architectural designs for buildings
B. To document employee schedules
C. To identify potential pollutant sources and describe control measures
D. To replace environmental permits
Answer: C
A SWPPP identifies risks associated with stormwater runoff and explains
the best management practices used to minimize pollution from the site.
, 5. Which Best Management Practice (BMP) is commonly used to reduce
sediment leaving a construction site?
A. Increasing vehicle traffic
B. Installing silt fences and sediment basins
C. Removing vegetation from slopes
D. Washing equipment directly into storm drains
Answer: B
Silt fences and sediment basins slow runoff and capture sediment before it
can leave the construction area and pollute waterways.
6. Why is sediment considered a major stormwater pollutant?
A. It increases water temperature only
B. It improves aquatic habitats in all cases
C. It can reduce water quality and harm aquatic organisms
D. It eliminates the need for erosion controls
Answer: C
Excess sediment can cloud water, reduce sunlight penetration, damage
aquatic habitats, and transport other pollutants attached to soil particles.
7. Which inspection finding would most likely indicate ineffective erosion
control?
A. Healthy vegetation covering disturbed areas
B. Clear stormwater discharge leaving the site
C. Visible sediment deposits outside the construction boundary
D. Properly maintained inlet protection
Answer: C
Sediment outside the permitted work area indicates that erosion controls
are failing and corrective actions are needed.
, 8. What is the purpose of inlet protection at a construction site?
A. To increase stormwater flow speed
B. To prevent sediment and debris from entering storm drains
C. To eliminate all runoff
D. To replace erosion control practices
Answer: B
Inlet protection devices capture sediment and debris before stormwater
enters drainage systems that discharge to receiving waters.
9. Which type of pollution is considered a nonpoint source pollution
problem?
A. A single pipe discharge from a factory
B. Runoff carrying pollutants from many areas during rainfall
C. A permitted wastewater treatment facility discharge
D. A documented industrial outfall
Answer: B
Nonpoint source pollution comes from widespread sources such as streets,
agricultural fields, and construction sites where runoff collects pollutants.
10. What should a stormwater inspector verify when reviewing a
SWPPP?
A. Whether the document contains employee vacation schedules
B. Whether required BMPs are identified and properly implemented
C. Whether the contractor has completed architectural drawings
D. Whether the project has exceeded its construction budget
Answer: B
Inspectors review SWPPPs to confirm that pollution risks have been
identified and appropriate stormwater controls are being maintained.
