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
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
Erosion control vs. Sediment Control - ANSWER-- Erosion control measures (mulch,
blankets, mats, vegetative cover) protect the soil surface and prevent soil particles from
being dislodged and carried away by wind or water.
- Sediment control measures remove soil particles after they have been dislodged
(typically thought settling or filtration).
