Exam Questions And Answers 100% Pass
What two plans in the SWPPP must be approved? - ANS Erosion and sediment control plans
and stormwater management plans must be approved.
Does the stormwater management plan address runoff during construction or after? -
ANS The stormwater management plan addresses post-construction stormwater runoff.
What impact does impervious cover have on water quality? - ANS The volume and velocity of
stormwater runoff increases as natural vegetation is replaced with roads, buildings, parking
areas and other impervious surfaces. The increase in stormwater runoff leads to an increase in
pollutants, such as sediment and phosphorus that are carried to waterways, which has a
negative effect on water quality.
What is the target pollutant in the water quality criteria ? - ANS Phosphorus
What is the lower limit of the range of imperviousness that scan result in stream degradation? -
ANS 10%
The SWM regulation ensures water quantity is considered in stormwater management planning
to protect against which two destructive forces? - ANS Channel erosion and flooding.

Discuss how the rate of runoff changes after development. - ANS The rate of runoff increase
after development because of the replacement of vegetation with impervious surfaces. A larger
volume of water will travel more quickly through a stream channel, potentially causing erosion
and flooding.
A locality VSMP must be at least as stringent as what state permit? - ANS Construction GP
(9VAC25-870-106).
What plans must a locality's ordinance require to be submitted and approved? - ANS ESC
plan and SWM plan (9VAC25-870-148)
List three violations for which a penalty may be imposed. - ANS (9VAC25-870-116)
*No registration date
*No SWPPP
*Incomplete SWPPP
*SWPPP not available for review
*No approves ESC plan
*Failure to install stormwater management BMPs or ESCs
