ARE – SWPPP PRACTICE EXAM QUESTIONS WITH COMPLETE SOLUTIONS

What is an SWPPP? correct 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: correct answer: Controlling the volume of stormwater runoff Impervious surfaces such as buildings, homes, roads, sidewalks, and parking lots, can significantly: correct 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: correct 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: correct answer: approx. 35-45 tons of sediment per acre each year The primary stormwater pollutant at a construction site is: correct answer: Sediment Vegetative cover provides a number of critical benefits in preventing erosion: correct 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: correct answer: Control sediment from leaving a
