Question 1
What is the primary purpose of a construction site stormwater inspection?
A. Determine the project's construction budget
B. Approve architectural designs
C. Evaluate whether stormwater controls are properly installed, maintained,
and functioning as required
D. Determine the contractor's production rate
Rationale: A stormwater inspection evaluates the condition and effectiveness of
required controls and identifies deficiencies that may require maintenance or
corrective action.
Question 2
Which document should an inspector generally review before conducting a
permitted construction-site inspection?
A. The contractor's payroll records
B. The Stormwater Pollution Prevention Plan (SWPPP)
C. The project's interior design drawings
D. Equipment purchase invoices
Rationale: The SWPPP identifies site-specific stormwater controls, drainage
features, pollutant sources, inspection procedures, and other requirements that
provide an important basis for the field inspection.
Question 3
What does SWPPP stand for?
,A. Surface Water Protection and Planning Program
B. Soil and Watershed Preservation Project Plan
C. Stormwater Work and Pollution Prevention Procedure
D. Stormwater Pollution Prevention Plan
Rationale: SWPPP is the standard abbreviation for Stormwater Pollution
Prevention Plan. It is used to identify potential sources of stormwater pollution
and the controls used to minimize those impacts.
Question 4
What is the main purpose of reviewing previous inspection reports before a new
inspection?
A. Determine the project's final cost
B. Identify recurring deficiencies and previously documented site conditions
C. Replace the current field inspection
D. Determine employee qualifications
Rationale: Previous reports can reveal recurring problems, unresolved deficiencies,
and areas that deserve particular attention during the current inspection.
Question 5
What is the primary difference between routine maintenance and corrective
action?
A. Routine maintenance applies only before construction begins
B. Corrective action applies only to vegetation
C. Routine maintenance addresses ordinary upkeep, while corrective action
addresses specified significant or compliance-related deficiencies
D. They are always identical
Rationale: Routine maintenance keeps controls in effective operating condition,
while corrective action is triggered by specified conditions such as significant
repairs, missing or incorrectly installed controls, certain discharge problems, or
prohibited discharges.
Question 6
,Which condition is most directly associated with routine maintenance of a
stormwater control?
A. A completely missing required control
B. A prohibited discharge
C. A major new control being required
D. Minor damage that can be repaired to restore the control's normal function
Rationale: Routine maintenance includes minor repairs and other upkeep needed
to keep controls operating effectively. More significant failures may trigger
corrective-action requirements depending on the applicable permit.
Question 7
What should an inspector do when a required stormwater control is missing?
A. Assume another control will compensate for it
B. Remove the requirement from the SWPPP
C. Document the deficiency and follow the applicable corrective-action process
D. Ignore the condition if no rain is occurring
Rationale: A required control that was never installed can represent a compliance
deficiency. The inspector should document the condition and follow the applicable
permit and project procedures.
Question 8
Which area should generally be included in a construction stormwater inspection?
A. Only the contractor's office
B. Only areas containing permanent buildings
C. Disturbed areas, stormwater controls, applicable storage areas, and site
drainage pathways
D. Only completed portions of the project
Rationale: Inspection coverage should include areas where construction activities
or stormwater controls can affect water quality. EPA inspection guidance
identifies disturbed areas, controls, storage areas, and stormwater flow areas
among the areas to inspect.
Question 9
, What is the primary purpose of inspecting material and equipment storage areas?
A. Determine equipment resale value
B. Identify potential sources of stormwater pollution such as spills, leaks,
exposed materials, or poor housekeeping
C. Verify employee attendance
D. Determine construction productivity
Rationale: Storage and maintenance areas can contain fuels, chemicals, waste,
soil, and other materials that may become pollutants if exposed to stormwater.
EPA inspection training specifically emphasizes inspecting these areas.
Question 10
What is the primary purpose of erosion-control measures?
A. Increase soil transport
B. Increase stormwater velocity
C. Prevent or minimize soil detachment
D. Eliminate all precipitation
Rationale: Erosion controls protect soil from being detached by rainfall, runoff,
wind, or other forces. Examples include vegetation, mulch, and erosion-control
blankets.
Question 11
What is the primary purpose of sediment-control measures?
A. Create additional soil disturbance
B. Intercept or retain sediment after it becomes mobile
C. Increase channel erosion
D. Eliminate infiltration
Rationale: Sediment controls capture, filter, or settle sediment transported by
runoff. They complement erosion controls, which focus on preventing soil
detachment.
Question 12
Which practice is primarily an erosion-control measure?
