Question 1
What is the primary purpose of a construction stormwater permit?
A. To regulate building height
B. To control pollutants discharged from construction-site stormwater runoff
C. To establish contractor licensing fees
D. To determine construction material prices
Construction stormwater permits are designed to reduce pollutants discharged in
stormwater runoff from regulated construction activities, particularly sediment
and other pollutants associated with disturbed land.
Question 2
Which pollutant is commonly associated with construction-site runoff?
A. Ozone
B. Carbon monoxide
C. Sediment
D. Natural gas
Sediment is one of the most common pollutants generated by construction
activities because clearing, grading, and excavation expose soil to rainfall and
runoff.
,Question 3
What does SWPPP commonly stand for?
A. Stormwater Work Protection and Planning Program
B. Stormwater Pollution Prevention Plan
C. Soil and Water Permitting Protection Procedure
D. Surface Water Pollution Permit Program
A SWPPP is a Stormwater Pollution Prevention Plan. It documents the site's
potential pollutant sources and the control measures that will be used to minimize
stormwater pollution.
Question 4
What is a major objective of a construction SWPPP?
A. Maximize soil disturbance
B. Eliminate all construction activity during rainfall
C. Establish employee payroll procedures
D. Identify potential pollutant sources and describe measures to control them
The SWPPP provides a site-specific framework for identifying pollutant sources
and implementing appropriate erosion, sediment, and pollution-prevention
controls.
Question 5
Which construction activity most directly increases the risk of sediment entering
stormwater?
A. Installing office furniture
B. Painting interior walls
C. Clearing and grading soil
D. Installing indoor lighting
Clearing and grading remove vegetation and disturb soil, increasing the amount of
exposed soil that can be transported by rainfall and runoff.
,Question 6
What is the main purpose of preserving existing vegetation on a construction
site?
A. Increase equipment traffic
B. Reduce soil exposure and erosion
C. Increase the amount of disturbed area
D. Eliminate the need for site inspections
Existing vegetation protects soil from raindrop impact and slows runoff.
Preserving vegetation can therefore reduce erosion and sediment transport.
Question 7
Which practice is generally considered a stabilization measure?
A. Increasing vehicle traffic over bare soil
B. Removing temporary vegetation
C. Expanding the disturbed area
D. Establishing permanent vegetation
Permanent vegetation stabilizes exposed soil by providing root reinforcement and
surface protection, reducing erosion after construction.
Question 8
What is the primary purpose of a stabilized construction entrance?
A. Increase vehicle speed
B. Store excavated soil
C. Reduce sediment tracked from the site onto public roads
D. Divert sanitary sewage
A stabilized entrance provides a controlled access point and uses appropriate
aggregate or other measures to reduce the amount of soil carried by construction
vehicles onto paved roads.
, Question 9
Why is sediment tracking onto public roads a stormwater concern?
A. It increases pavement strength
B. It reduces traffic
C. Sediment can be transported by runoff into storm drains and receiving waters
D. It improves road drainage
Sediment deposited on roads can later be washed into storm drains or nearby
surface waters, contributing to sediment pollution.
Question 10
What is the primary function of a silt fence?
A. Treat sanitary wastewater
B. Intercept and slow sediment-laden sheet flow from disturbed areas
C. Increase runoff velocity
D. Replace all site stabilization measures
Silt fences can intercept sheet flow and allow sediment to settle before runoff
leaves the disturbed area. They are most effective when properly installed and
used in appropriate flow conditions.
Question 11
Where should a silt fence generally be installed?
A. Across a major concentrated-flow channel
B. Inside a building
C. On a paved parking area
D. Along the downslope perimeter of a disturbed area where it can intercept
sheet flow
Silt fences are intended primarily for sheet-flow conditions. Concentrated flows
can overwhelm or bypass them, requiring other appropriate controls.
