STORM WATER COMPLIANCE
CONSTRUCTION FINAL PAPER TESTED
QUESTIONS WITH DETAILED SOLUTIONS
STUDY MATERIAL
●● Hazardous Materials
Answer: Any material, including any substance, waste or combination
thereof which because of its quantity, concentration, physical, chemical
or infectious characteristics may cause or significantly contribute to a
potential hazard to human health or safety, property, or the environment
when improperly treated, stored, transported, disposed of or otherwise
managed.
●● Illegal Discharge
Answer: Any direct or indirect non-storm water discharge to the MS4, or
conveyance. An illegal discharge can also include storm water
discharges that have not been properly treated by Best Management
Practices as outlined in the approved Permit.
●● Impermeable
Answer: A surface that prevents the infiltration of water.
●● Impervious Surface
, Answer: A term applied to any ground or structural surface that water
cannot penetrate or through which water penetrates with great difficulty.
●● Land Disturbance
Answer: The purposeful act of clearing, grubbing, excavating, or
grading; disrupting ground surface by or for construction activities,
including construction access/road, staging, and storage sites producing
significant areas of exposed soil and soil piles.
●● Level Spreader
Answer: A channel or bunker, typically made from concrete, at a zero
percent grade across a slope. Level spreaders spread out concentrated
flow into a sheet flow and reduce water velocity.
●● MS4 (Municipal Separate Storm Sewer System)
Answer: A system of inlets, conveyances, storage basins and outfalls in
which storm water is introduced, conveyed, stored or discharged.
●● National Pollutant Discharge Elimination Systems (NPDES)
Answer: EPA's program to control the discharge of pollutants to waters
of the United States.
●● Storm Water Pollution Prevention Plan (SWPPP)
