Question 1
What is the primary purpose of an environmental construction
management plan?
A. To eliminate all project costs
B. To replace engineering drawings
C. To identify and control environmental risks associated with
construction activities
D. To guarantee that no inspections will occur
Rationale: An environmental construction management plan establishes
procedures for identifying, preventing, monitoring, and correcting
environmental impacts during construction. It may address erosion,
,sediment, waste, hazardous materials, water quality, dust, and other
site-specific risks.
Question 2
Which construction activity has the greatest potential to cause soil
erosion?
A. Interior painting
B. Clearing and grading exposed soil
C. Installing cabinet hardware
D. Installing interior lighting
Rationale: Clearing vegetation and grading disturb and expose soil.
Rainfall and runoff can then transport loose sediment to drainage
systems and surface waters. Proper erosion and sediment controls
should therefore be installed before and during earthwork.
Question 3
What is the main purpose of an erosion-control measure?
A. Increase vehicle traffic
B. Improve concrete strength
C. Prevent soil from being detached and transported by wind or water
D. Reduce electrical consumption
,Rationale: Erosion occurs when soil particles are detached and moved
by water or wind. Measures such as mulching, vegetation, erosion-
control blankets, and stabilized slopes reduce the potential for soil loss.
Question 4
What is the primary purpose of sediment-control measures?
A. Prevent all excavation
B. Capture or retain sediment before it leaves the construction site
C. Increase excavation depth
D. Accelerate stormwater runoff
Rationale: Sediment controls are intended to intercept sediment after it
has been mobilized. Examples include sediment basins, silt fences, inlet
protection, and sediment traps.
Question 5
Which condition generally increases the risk of construction-site
erosion?
A. Dense established vegetation
B. Flat, fully stabilized ground
C. Steep slopes with exposed soil
D. Completed pavement
, Rationale: Steep exposed slopes allow runoff to gain velocity and carry
greater quantities of soil. Stabilization and properly designed drainage
controls are especially important on steep or disturbed areas.
Question 6
Why should construction entrances be stabilized?
A. To increase sediment production
B. To eliminate the need for site inspections
C. To reduce soil and sediment tracked onto public roads
D. To increase vehicle speed
Rationale: Vehicles leaving a construction site can carry mud and
sediment onto public roads. A stabilized entrance helps remove soil
from tires and limits tracking onto roadways and adjacent properties.
Question 7
Which practice is most effective for reducing dust from an active
unpaved construction road?
A. Increasing vehicle speed
B. Removing all vegetation nearby
C. Applying water or another approved dust-control method
D. Disturbing additional soil
