CISEC Exam Questions and Answers Already Graded
Stormwater control design goal
Ans: Minimize the discharge of pollutants in stormwater.
SW control design factors
Ans: 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
Ans: 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
Ans: 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
Ans: Must be installed upgradient of any natural buffers, extend on the contour of a slope with ends
curved upwards.
Maintaining perimeter controls
Ans: 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
Ans: Restricting vehicle use to designated points and installing tracking controls like wheel washing,
rumble plates, and 3-inch gravel.

, Ans: Away from inlets or concentrated flow areas, install a sediment barrier along downgradient
areas, and if unused for 14+ days provide cover.
Minimizing dust
Ans: On areas of exposed soil, apply water or other suppression techniques.
Soil health factors
Ans: Minimize steep slope disturbances, preserve native topsoil unless infeasible, and minimize soil
compaction.
Inlet protection
Ans: 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
Ans: 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
Ans: 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
Ans: Must collect a sample from dewatering discharge each day a discharge occurs, and after it has
been treated.
