1.Under the National Pollutant Discharge Elimination System (NPDES), the
primary purpose of a stormwater permit for an industrial facility is to:
A. Regulate groundwater withdrawals
B. Control pollutants discharged in stormwater to waters of the
United States
C. Regulate indoor air emissions
D. Control drinking water treatment processes
Rationale: The NPDES Stormwater Program is designed to reduce
pollutants in stormwater runoff from industrial facilities,
construction sites, and municipal separate storm sewer systems
before they reach waters of the United States.
1. Which federal law established the NPDES permitting program?
A. Safe Drinking Water Act
B. Clean Water Act
, C. Resource Conservation and Recovery Act
D. Toxic Substances Control Act
Rationale: The Clean Water Act created the NPDES program to
regulate point source discharges into waters of the United States.
2. Which of the following is considered stormwater pollution?
A. Rainwater that falls directly into a lake
B. Clean groundwater seepage
C. Rainwater that carries oil, sediment, or chemicals from industrial
areas
D. Distilled water discharged from a laboratory
Rationale: Stormwater becomes polluted when it contacts industrial
materials, chemicals, waste, sediment, or other contaminants before
entering waterways.
3. A Stormwater Pollution Prevention Plan (SWPPP) primarily serves to:
A. Estimate facility tax obligations
B. Identify pollutant sources and describe measures to minimize
stormwater contamination
C. Determine employee salaries
D. Manage hazardous waste manifests
Rationale: A SWPPP identifies potential pollutant sources and
outlines best management practices (BMPs), inspections, and
monitoring procedures to reduce stormwater pollution.
4. Which activity is considered a Best Management Practice (BMP)?
, A. Leaving drums uncovered outdoors
B. Installing spill containment around chemical storage areas
C. Washing equipment into storm drains
D. Disposing waste into drainage ditches
Rationale: Secondary containment helps prevent spills from reaching
stormwater and is a commonly required BMP.
5. The purpose of routine facility inspections is to:
A. Increase production efficiency only
B. Identify conditions that may contribute to stormwater pollution
C. Eliminate OSHA requirements
D. Monitor employee attendance
Rationale: Routine inspections help identify leaks, spills, damaged
controls, and other issues before pollutants are discharged.
6. Which material should generally be stored under cover whenever
possible?
A. Clean gravel
B. Chemicals susceptible to contact with rainfall
C. Empty pallets
D. Office furniture
Rationale: Protecting chemicals from precipitation minimizes the risk
of contaminated stormwater runoff.
7. Secondary containment is intended to:
, A. Improve air quality
B. Capture spills before they reach the environment
C. Increase equipment speed
D. Reduce electrical hazards
Rationale: Secondary containment prevents accidental releases from
migrating into stormwater systems.
8. Which stormwater discharge is generally prohibited unless
authorized?
A. Uncontaminated rainfall
B. Unauthorized discharge of industrial pollutants
C. Snowmelt
D. Natural runoff from undisturbed forests
Rationale: Industrial stormwater discharges containing pollutants
require permit authorization and compliance with permit conditions.
9. Employees should immediately report:
A. Completed lunch breaks
B. Spills and leaks that may affect stormwater
C. Vacation requests
D. Computer software updates
Rationale: Prompt reporting enables rapid response to minimize
environmental impacts.
11. Good housekeeping practices include:
