SWPPP CORRECT TEST PAPER QUESTIONS AND
ANSWERS SET A+
✔✔Who is required to get NPDES Permit Coverage? - ✔✔- Construction site operators
Operators may include:
- GCs, independent subs, government officials, companies, or corporations
- Any party that has control over the construciton plans ans specs and/or
- Has day-to-day operational control of the site
✔✔Erosion control vs. Sediment Control - ✔✔- Erosion control measures (mulch,
blankets, mats, vegetative cover) protect the soil surface and prevent soil particles from
being dislodged and carried away by wind or water.
- Sediment control measures remove soil particles after they have been dislodged
(typically thought settling or filtration).
It is usually easier and less expensive to prevent erosion than it is to control
sedimentation.
✔✔Common SWPPP Objectives: - ✔✔- Stabilize the site as soon as possible
- Protect slopes and channels
- Reduce impervious surfaces and promote infiltration
- Control the perimeter of your site
- Protect receiving waters adjacent to your site
- Follow pollution prevention measures
- Minimizes the area and duration of exposed soils
✔✔The first step in developing an SWPPP: - ✔✔Evaluate your proposed construction
site. It should describe the undeveloped site and identify features of the land that can be
incorporated into the final plan and natural resources that should be protected.
, ✔✔Assess existing construction site conditions: - ✔✔- Assess how stormwater currently
drains from the site, identify location of discharge points or areas
- Identify slopes and slope lengths
- Identify soil types and any highly erodible soils and the soil's infiltration capacity
- Identify past soil contaminants
- Identify natural features
✔✔Fingerprinting - ✔✔Identifies natural features that you can protect from clearing and
heavy equipment by signage or physical barriers.
✔✔If your site's stormwater flows into a municipal storm drain system, you should: -
✔✔Determine the ultimate destination of that system's discharge.
✔✔If your site's stormwater could potentially reach two or more waterbodies, - ✔✔not
that in your SWPPP
✔✔The principal pollutant of concern is: - ✔✔sediment
✔✔Allowable non-stormwater discharges: - ✔✔- Discharges from fire-fighting activities
- Fire hydrant flushings
- Waters used to wash vehicles
- Buildings and pavements where detergents are not used
- Water used to control dust
- Potable water (including uncontaminated water line flushings)
- Uncontaminated air conditioning condensate
- Uncontaminated ground water or spring water
✔✔Permanent stormwater controls should be designed with 2 important goals in mind: -
✔✔1. Reduction of the volume and velocity of runoff
2. Reduction of the pollutants in the stormwater that does leave your site.
✔✔Total Maximum Daily Load (TMDL) - ✔✔A plan for correcting a situation, developed
from the state or EPA, for when a water is determined to be impaired.
✔✔Site maps should legibly identify the following features: - ✔✔- Stormwater flow and
discharges
- Areas and features to be protected
- Disturbed areas
- BMPs
- Areas of stabilization
- Other areas and roads (waste/storage)
✔✔The heart of any effective SWPPP: - ✔✔Erosion control, primary means of
preventing stormwater pollution
