DEQ- STORMWATER MANGEMENT INSPECTOR EXAM QUESTIONS AND ANSWERS 2025
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)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? - (ANSWER)Phosphorus
What is the lower limit of imperviousness that can result in stream degradation? - (ANSWER)10%
What destructive forces does the SWM regulation protect against? - (ANSWER)Channel erosion and
flooding.
How does the rate of runoff change after development? - (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? - (ANSWER)ESC plan and SWM
plan (9VAC25-870-148)
List three violations for which a penalty may be imposed. - (ANSWER)Violations include: No registration
date, No SWPPP, Incomplete SWPPP, SWPPP not available for review, No approved ESC plan, Failure to
install stormwater management BMPs or ESCs, Improperly installed or maintained stormwater BMPs or
ESCs, Operational deficiencies, Failure to conduct required inspections, Incomplete, improper, or missed
inspections.
Maximum Penalty under the Stormwater Act - (ANSWER)$32,500
