CISEC Exam Comprehensive Questions
(Frequently Tested) with Verified
Answers Graded A+
Stormwater control design goal - Answer: Minimize the discharge of pollutants in stormwater.
SW control design factors - Answer: Expected amount and frequency of precipitation, soil type
and range, flow from impervious surfaces, slopes, and BMPs to control flow rates.
Erosion and sediment control requirements - Answer: Provide and maintain natural buffers
and/or equivalent erosion and sediment controls for discharges to any receiving waters located
within 50 feet of the site's earth disturbances.
Directing stormwater - Answer: Towards vegetated areas, maximize infiltration and filtering to
minimize pollutant discharges unless unadvisable due to geological factors (GW contamination,
karst geography, etc.)
Installing perimeter controls - Answer: Must be installed upgradient of any natural buffers,
extend on the contour of a slope with ends curved upwards.
Maintaining perimeter controls - Answer: Remove sediment before it has accumulated to 1/2
the height of the control, and if it is ineffective following a precipitation event: extend or repair
controls.
Minimizing sediment track-out - Answer: Restricting vehicle use to designated points and
installing tracking controls like wheel washing, rumble plates, and 3-inch gravel.
, Managing stockpiles - Answer: Away from inlets or concentrated flow areas, install a sediment
barrier along downgradient areas, and if unused for 14+ days provide cover.
Minimizing dust - Answer: On areas of exposed soil, apply water or other suppression
techniques.
Soil health factors - Answer: Minimize steep slope disturbances, preserve native topsoil unless
infeasible, and minimize soil compaction.
Inlet protection - Answer: Install protection measures that remove sediment from discharges
prior to entry (not required for sites with a sediment trap system); and clean or replace
protections as sediment accumulates.
Chemical use and storage - Answer: Must be appropriately suited for soil type and treated
discharges. Must be stored in leak-proof containers under storm-resistant covers and
surrounded by secondary containment.
Exposed soil - Answer: Must be stabilized and resistant to erosion.
Timeline:
5 acres or less--begin stabilizing where activity stops permanently or for more than 14 days
immediately, no more than 14 days.
More than 5 acres--begin stabilizing where activity stops permanently or for more than 14 days
immediately, no more than 7 days.
Turbidity monitoring--dewatering - Answer: Must collect a sample from dewatering discharge
each day a discharge occurs, and after it has been treated.
Turbidity benchmark - Answer: 50 NTUs
