CISEC Exam Questions and Answers Already Graded
When working in waterways or wetlands, which permit is required?
Ans: 404 Permit
NPDES
Ans: National Pollutant Discharge Elimination System
Section of CWA (Clean Water Act) to permit stormwater discharges associated with industrial
activities per the permit
CWA Penalty Types
Ans: Class I. Negligent
Class II. Knowingly = Greater Fines
What documents are required onsite?
Ans: SWPPP
CGP
Site Map
Drawings and Key
All inspection reports
Any amendments to SWPPP
Who is the "Operator"
Ans: Usually the OWNER of the site, not the contractor, unless authorized by the owner to general
contractor to have day-to-day operational control
Vertical Projects

,Ans: Homebuilding, smaller residential construction projects
Usually multiple subcontractors
Requires a lot of housekeeping
LDP
Ans: Land Developing Projects - altering landscape for projects
Big Box Projects
Ans: Commercial buildings
Mass grading and mass chaos
Limits site access and continually changing (high activity)
Linear Priojects
Ans: Roadways, utilities, and stream corridors
Long narrow sites and mass chaos
Highly visible with fairly large footprint
What is erosion?
Ans: The process by which soil particles get displaced by the act of wind or water
What are three types of wind erosion
Ans: Surface Creep, Saltation, and Suspension
What is surface creep?
Ans: Rolling and sliding movement of particles across a surface. 5-25% total soil loss by wind
What is saltation?
Ans: Hopping and bouncing movement of particles. 50-80% total soil loss by wind
What is suspension?

, Ans: Small, lightweight particles carried great distances by wind. Less than 10% total soil loss by
wind
What are the types of water erosion?
Ans: Raindrop erosion, sheet erosion, rill and gully erosion, stream and channel erosion, shoreline
erosion, landslides
What is sheet erosion?
Ans: Stripping of soil that occurs due to sheet flows of runoff
Rill and Gully Erosion
Ans: If the runoff is allowed to concentrate and gain velocity or energy, it will cut rills and gullies as it
detaches more soil particles
Rills: </= to 3" deep
Gullies: 3 or more rills converted to greater that 3" deep
Streambank/Channel Erosion
Ans: Removal of soil and other embankment materials due to concentrated channel flows
T/F: Rills are more than 75mm deep and are often the start of gullies
Ans: False: gullies are more than 75mm deep
What factors impact rainfall erosion?
Ans: Climate events, soil erodibility, length of flow down a slope, slope of land (critical), erosion
control BMPs, sediment control BMPs
T/F: Clay is highly erodible
Ans: False
What is sediment?
