SWPPP EXAMPREP REVIEW SHEET TESTED
QUESTIONS AND ACCURATE ANSWERS
●● 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
