1. The primary purpose of an NPDES Construction Stormwater Permit is
to regulate which of the following activities?
A. Discharge of treated drinking water
B. Stormwater discharges associated with construction activities
C. Industrial wastewater from manufacturing facilities
D. Agricultural irrigation runoff
B. Stormwater discharges associated with construction activities
The NPDES Construction Stormwater Permit is specifically designed to
control pollutants in stormwater runoff from construction sites that disturb
land.
2. NPDES stands for which of the following?
A. National Pollution Discharge Evaluation System
B. National Permit Drainage Enforcement Standard
C. National Pollutant Discharge Elimination System
D. National Prevention of Drainage and Erosion System
C. National Pollutant Discharge Elimination System
,NPDES is the federal permitting program established under the Clean
Water Act to regulate pollutant discharges into waters of the United
States.
3. Which federal law authorizes the NPDES permitting program?
A. Safe Drinking Water Act
B. Clean Water Act
C. Resource Conservation and Recovery Act
D. Endangered Species Act
B. Clean Water Act
The Clean Water Act created the legal framework for regulating pollutant
discharges through programs such as NPDES.
4. A construction project generally requires an NPDES stormwater permit
when it disturbs how much land area?
A. One acre or more
B. One-half acre or more
C. Five acres or more only
D. Ten acres or more only
A. One acre or more
Federal construction stormwater regulations generally apply to projects
disturbing one or more acres of land, including certain smaller projects
that are part of larger developments.
5. The document that describes how a construction site will prevent
stormwater pollution is called the:
A. Spill Prevention Plan
B. Stormwater Pollution Prevention Plan (SWPPP)
C. Environmental Impact Report
D. Construction Safety Manual
B. Stormwater Pollution Prevention Plan (SWPPP)
,The SWPPP identifies potential pollution sources and establishes control
measures to minimize stormwater impacts.
6. Who is typically responsible for obtaining coverage under an NPDES
Construction Stormwater Permit?
A. Any nearby property owner
B. The construction permittee or operator with control over the site
C. Local residents
D. Equipment manufacturers
B. The construction permittee or operator with control over the site
The operator who has control over construction activities or site plans is
generally responsible for permit compliance.
7. Which pollutant is most commonly associated with construction
stormwater runoff?
A. Sediment
B. Chlorine
C. Radioactive waste
D. Medical waste
A. Sediment
Construction activities expose soil, making sediment the most common
pollutant transported by stormwater runoff.
8. The main purpose of erosion controls at a construction site is to:
A. Increase soil movement
B. Prevent soil from leaving disturbed areas
C. Eliminate all construction activity
D. Replace storm drains
B. Prevent soil from leaving disturbed areas
Erosion controls stabilize soil and reduce the amount of sediment carried
away by runoff.
, 9. Which of the following is considered a perimeter control?
A. Silt fence
B. Concrete mixer
C. Excavator
D. Generator
A. Silt fence
Silt fences are installed around disturbed areas to intercept sediment
before it leaves the construction site.
10. A sediment basin is primarily used to:
A. Store fuel
B. Treat drinking water
C. Allow sediment to settle before stormwater discharge
D. Increase runoff velocity
C. Allow sediment to settle before stormwater discharge
Sediment basins temporarily hold runoff so suspended particles can settle
before water leaves the site.
11. Which stormwater control practice reduces erosion by
protecting exposed soil surfaces?
A. Soil stabilization
B. Increasing excavation depth
C. Removing vegetation
D. Clearing drainage channels
A. Soil stabilization
Stabilizing exposed soil with vegetation, mulch, or other materials reduces
erosion caused by wind and water.
12. A construction site inspection under an NPDES permit is
performed primarily to:
A. Increase project costs
