sediment control plans and stormwater management plans must be approved.
Does the stormwater management plan address runoff during construction or after? - CORRECT
ANSWER - The stormwater management plan addresses post-construction stormwater
runoff.
What impact does impervious cover have on water quality? - CORRECT ANSWER -
Impervious cover increases stormwater runoff volume and velocity, leading to higher pollutant
levels like sediment and phosphorus, negatively affecting water quality.
What is the target pollutant in the water quality criteria? - CORRECT ANSWER -
Phosphorus
What is the lower limit of imperviousness that can result in stream degradation? - CORRECT
ANSWER - 10%
What destructive forces does the SWM regulation protect against? - CORRECT
ANSWER - Channel erosion and flooding.
How does the rate of runoff change after development? - CORRECT ANSWER - Runoff
rate increases post-development due to vegetation replacement with impervious surfaces,
potentially causing erosion and flooding.
What must a locality's ordinance require for submission and approval? - CORRECT
ANSWER - ESC plan and SWM plan (9VAC25-870-148)

to conduct required inspections, Incomplete, improper, or missed inspections.
Maximum Penalty under the Stormwater Act - CORRECT ANSWER - $32,500
Locality VSMP Authority Registration Statement Retention - CORRECT ANSWER -
Must be documented and retained for at least three years from project completion or permit
termination
DEQ Program Reviews Frequency - CORRECT ANSWER - DEQ conducts a program
review once every five years

control measures
Locations for Notice of Coverage Letter Posting - CORRECT ANSWER - Near main
entrance of construction activity and in general information section of SWPPP
Options for Making SWPPP Available to Public - CORRECT ANSWER - Electronic
format or hard copy upon request at a publicly accessible location
