SWM Inspector
Knowledge
Check questions
and answers
Which two plans in the SWPPP must be approved? - answer ESC
plan and SWM plan
Does the SWM plan address runoff during construction or after? -
answer Post-construction
What impact does impervious cover have on water quality? -
answer More impervious cover means more stormwater runoff
(increased volume and velocity) that can pick up pollutants and
be carried to streams, impacting water quality
What is the target pollutant in the water quality criteria? - answer
Phosphorus
What is the lower limit of the range of imperviousness that can
result in stream degradation? - answer 10%
, The SWM regulation ensures water quantity is considered in
stormwater management planning to protect against which two
destructive forces? - answer Channel erosion and flooding
How does the rate of runoff changes after development? - answer
In a pre-development watershed, the peak discharge gradually
increases and gradually declines. In a post-development
watershed, the peak discharge increases much faster and to a
much higher amount (2-5x) than pre-development conditions and
declines much more abruptly. This is due to more impervious
cover in post-development and could potentially cause erosion
and flooding.
A locality VSMP must be at least as stringent as what state
permit? - answer Construction General Permit (General VDPES
Permit)
What plans must a locality's ordinance require to be submitted
and approved? - answer An approved ESC and SWM plan
List three violations for which a penalty may be imposed. - answer
Any of the following:
- no state permit
- no SWPPP
- incomplete SWPPP
- SWPPP not available for review
- no approved ESC plan
- failure to install E&S controls or stormwater BMPs
- failure to properly install or maintain E&S controls or stormwater
BMPs
