DEQ- STORMWATER MANAGEMENT
INSPECTOR TEST WITH 100% CORRECT
ANSWERS
What two plans in the SWPPP must be approved? - ANSWER:
Erosion and sediment control plans and stormwater management
plans must be approved.
Does the stormwater management plan address runoff during
construction or after? - ANSWER: The stormwater management plan
addresses post-construction stormwater runoff.
What impact does impervious cover have on water quality? -
ANSWER: 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 ? - ANSWER:
Phosphorus
What is the lower limit of the range of imperviousness that scan 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.
, Discuss how the rate of runoff changes after development. -
ANSWER: 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? -
ANSWER: Construction GP (9VAC25-870-106).
What plans must a locality's ordinance require to be submitted and
approved? - ANSWER: ESC plan and SWM plan (9VAC25-870-148)
List three violations for which a penalty may be imposed. - ANSWER:
(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
