1. What is the primary purpose of the NPDES stormwater program?
A. Increase the amount of impervious surface in developed areas
B. Reduce the discharge of pollutants associated with stormwater runoff
C. Eliminate all stormwater from developed areas
D. Regulate only drinking-water treatment facilities
Rationale: The NPDES stormwater program regulates certain stormwater
discharges to reduce pollutants transported by runoff into surface waters. The
program addresses municipal, construction, and industrial sources.
2. Which three major source categories are addressed by the federal NPDES
stormwater program?
A. Agriculture, wastewater treatment, and drinking water
B. Mining, agriculture, and household plumbing
C. Construction, agriculture, and groundwater
D. MS4s, construction activities, and industrial activities
Rationale: EPA identifies municipal separate storm sewer systems (MS4s),
construction activities, and industrial activities as the three major potential
stormwater discharge sources regulated under the NPDES stormwater program.
(US EPA)
,3. What is the primary purpose of a Stormwater Pollution Prevention Plan
(SWPPP)?
A. Establish employee payroll procedures
B. Replace the requirements of an NPDES permit
C. Identify potential pollutant sources and describe measures to control them
D. Determine property tax obligations
Rationale: A SWPPP documents how a facility or construction operator will identify
potential sources of stormwater pollution and implement appropriate control
measures to minimize pollutant discharges.
4. Which item would normally be important on a stormwater site map?
A. Employee vacation schedules
B. Stormwater drainage pathways and discharge points
C. Office furniture locations
D. Payroll records
Rationale: A useful stormwater site map identifies drainage features, discharge
points, pollutant source areas, and relevant stormwater control measures so that
compliance personnel can understand how runoff moves through the site.
5. What is the primary purpose of a Best Management Practice (BMP) in
stormwater management?
A. Increase pollutant concentrations
B. Eliminate the need for inspections
C. Increase runoff velocity
D. Prevent or reduce the release of pollutants
Rationale: BMPs are practices or control measures designed to prevent pollution
at its source or reduce pollutants carried by stormwater runoff.
6. Which condition presents the greatest potential for stormwater
contamination from stored industrial materials?
,A. Materials stored in a sealed indoor area
B. Materials protected by effective secondary containment
C. Pollutant-containing materials exposed to rainfall and runoff
D. Empty containers stored under a roof
Rationale: When pollutant-containing materials are exposed to precipitation and
runoff, pollutants can be mobilized and transported toward stormwater drainage
systems.
7. What is the primary purpose of secondary containment around a liquid
storage area?
A. Increase tank capacity
B. Improve vehicle access
C. Increase stormwater flow
D. Contain releases from the primary storage container
Rationale: Secondary containment provides an additional barrier that can capture
spills or leaks if the primary container fails, reducing the likelihood that pollutants
reach stormwater.
8. Which activity is most likely to create an industrial stormwater exposure?
A. Indoor administrative work
B. Outdoor handling of pollutant-containing materials
C. Office computer use
D. Indoor employee training
Rationale: Outdoor material handling can expose pollutants to precipitation and
runoff. EPA's industrial stormwater program focuses on activities and materials
that can contribute pollutants to stormwater discharges. (US EPA)
9. What should an inspector first compare during a stormwater compliance
inspection?
, A. Employee schedules and payroll records
B. Vehicle mileage and fuel consumption
C. Actual site conditions with applicable permit and SWPPP requirements
D. Building color with architectural plans
Rationale: Compliance inspections evaluate whether site activities and controls
conform to applicable permit requirements and the facility's or project's
documented stormwater controls.
10. Why should stormwater BMPs be inspected regularly?
A. To increase the number of site violations
B. To eliminate documentation
C. To prevent all rainfall
D. To verify that controls remain installed, maintained, and functional
Rationale: BMP performance can decline because of sediment accumulation,
damage, improper installation, or changing site conditions. Regular inspections
help identify these problems.
11. What is the primary purpose of corrective action in stormwater compliance?
A. Hide evidence of a violation
B. Address the cause or condition contributing to noncompliance
C. Eliminate monitoring requirements
D. Replace the applicable permit
Rationale: Corrective action is intended to address identified deficiencies or
pollutant sources and restore or improve compliance.
12. A stormwater inspection identifies a damaged sediment barrier. What is the
most appropriate compliance response?
A. Ignore the condition until the project ends
B. Remove all other stormwater controls
