ARE - SWPPP Comprehensive
Questions with Verified
Answers Graded A+
What is an SWPPP? - Answer: - Identifies potential sources of stormwater pollution at the
construction site
- Describes practices to reduce pollutants in storm water discharges from the construction site
- Identifies procedures the operator will implement to comply with the terms and conditions of
a construction general permit
Reduction of pollutants is often achieved by: - Answer: Controlling the volume of stormwater
runoff
Impervious surfaces such as buildings, homes, roads, sidewalks, and parking lots, can
significantly: - Answer: Alter the natural hydrology of the land by increasing the volume,
velocity, and temperature of runoff and by decreasing its infiltration capacity.
Increasing the volume and velocity of stormwater runoff can cause: - Answer: - Severe stream
bank erosion
- Flooding
- Degrade the biological habitat of these streams
Runoff from an unstabilized construction site can result in the loss of: - Answer: approx. 35-45
tons of sediment per acre each year
, The primary stormwater pollutant at a construction site is: - Answer: Sediment
Vegetative cover provides a number of critical benefits in preventing erosion: - Answer: -
Absorbs the energy of raindrops
- Slows velocity of runoff
- Increases infiltration
- Helps bind the soil
It is usually easier and less expensive to prevent erosion than it is to: - Answer: Control sediment
from leaving a construction site
Erosion vs. Sedimentation - Answer: *Erosion* - the process by which the land surface is worn
away by the action of water or wind.
*Sedimentation* - the movement and settling out of suspension of soil particles
Structural BMPs - Answer: - Silt Fences
- Sedimentation Ponds
- Erosion Control Blankets
- Temporary/Permanent Seeding
Non-Structural BMPs - Answer: - Picking up trash and debris
- Sweeping up nearby sidewalks and streets
- Maintaining equipment
- Training site staff on erosion and sediment control practices
