Question 1
What is the primary purpose of an industrial stormwater inspection?
A. Evaluate employee productivity
B. Determine the market value of the facility
C. Assess whether stormwater controls and pollution-prevention practices are
functioning as required
D. Approve industrial production schedules
Correct Answer: C. Assess whether stormwater controls and pollution-
prevention practices are functioning as required
Rationale: An industrial stormwater inspection evaluates site conditions, potential
pollutant sources, stormwater controls, discharges, and compliance with
applicable permit requirements.
Question 2
What does NPDES stand for?
A. National Pollutant Discharge Elimination System
B. National Pollution Development Evaluation Standard
C. National Drainage Protection Enforcement System
D. National Discharge Prevention Evaluation Standard
Correct Answer: A. National Pollutant Discharge Elimination System
,Rationale: NPDES is the federal permitting program established under the Clean
Water Act to regulate point-source discharges of pollutants to waters of the
United States.
Question 3
What is the primary purpose of an industrial Stormwater Pollution Prevention
Plan?
A. Establish employee compensation
B. Identify pollutant sources and describe measures used to control stormwater
pollution
C. Establish production quotas
D. Determine equipment replacement schedules
Correct Answer: B. Identify pollutant sources and describe measures used to
control stormwater pollution
Rationale: An industrial SWPPP documents potential pollutant sources,
stormwater control measures, inspection and monitoring procedures, schedules,
and other information necessary to manage stormwater discharges.
Question 4
Which area is particularly important to inspect at an industrial facility?
A. Employee parking only
B. Office reception areas
C. Areas where industrial materials or activities are exposed to stormwater
D. Administrative offices with no stormwater exposure
Correct Answer: C. Areas where industrial materials or activities are exposed to
stormwater
*Rationale: Industrial materials or activities exposed to stormwater can become
pollutant sources. The 2021 MSGP specifically identifies these areas as inspection
locations. *
,Question 5
Which condition should an inspector specifically look for around industrial
equipment?
A. Equipment color
B. Leaks or spills
C. Equipment purchase price
D. Manufacturer advertising
Correct Answer: B. Leaks or spills
*Rationale: Leaks and spills from equipment, drums, tanks, and containers can
introduce pollutants into stormwater and are specifically identified as inspection
concerns under the MSGP. *
Question 6
What is the primary function of an industrial stormwater control measure?
A. Increase pollutant exposure
B. Increase stormwater velocity
C. Minimize or eliminate pollutants in stormwater discharges
D. Increase industrial production
Correct Answer: C. Minimize or eliminate pollutants in stormwater discharges
Rationale: Industrial stormwater permits require control measures designed to
reduce pollutant exposure and prevent or minimize pollutant discharges
associated with industrial activity.
Question 7
Which document should an inspector review to identify potential pollutant
sources at a facility?
, A. Employee attendance sheet
B. Facility SWPPP
C. Equipment warranty
D. Purchase order
Correct Answer: B. Facility SWPPP
Rationale: The SWPPP identifies potential pollutant sources and the stormwater
controls used to address them, making it an essential inspection reference.
Question 8
What is an industrial stormwater outfall?
A. A location where stormwater leaves the facility through a discharge point
B. A building entrance
C. A material storage room
D. An employee parking area
Correct Answer: A. A location where stormwater leaves the facility through a
discharge point
Rationale: Outfalls are discharge locations through which stormwater exits a
facility. Monitoring and visual assessments are generally performed at applicable
discharge points.
Question 9
Where are industrial stormwater samples generally collected when monitoring is
required?
A. Inside administrative offices
B. At the facility's stormwater discharge points
C. Inside production machinery
D. From drinking-water faucets
Correct Answer: B. At the facility's stormwater discharge points
