DETAILED ANSWERS| LATEST UPDATE
When working in waterways or wetlands, which permit is required? - CORRECT
ANSWER- 404 Permit
NPDES - CORRECT ANSWER- 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 - CORRECT ANSWER- Class I. Negligent
Class II. Knowingly = Greater Fines
What documents are required onsite? - CORRECT ANSWER- SWPPP
CGP
Site Map
Drawings and Key
All inspection reports
Any amendments to SWPPP
Who is the "Operator" - CORRECT ANSWER- 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 - CORRECT ANSWER- Homebuilding, smaller residential
construction projects
Usually multiple subcontractors
Requires a lot of housekeeping
LDP - CORRECT ANSWER- Land Developing Projects - altering landscape for
projects
Big Box Projects - CORRECT ANSWER- Commercial buildings
Mass grading and mass chaos
Limits site access and continually changing (high activity)
Linear Priojects - CORRECT ANSWER- Roadways, utilities, and stream
corridors
Long narrow sites and mass chaos
Highly visible with fairly large footprint
What is erosion? - CORRECT ANSWER- The process by which soil particles get
displaced by the act of wind or water
What are three types of wind erosion - CORRECT ANSWER- Surface Creep,
Saltation, and Suspension
What is surface creep? - CORRECT ANSWER- Rolling and sliding movement of
particles across a surface. 5-25% total soil loss by wind
,What is saltation? - CORRECT ANSWER- Hopping and bouncing movement of
particles. 50-80% total soil loss by wind
What is suspension? - CORRECT ANSWER- Small, lightweight particles carried
great distances by wind. Less than 10% total soil loss by wind
What are the types of water erosion? - CORRECT ANSWER- Raindrop erosion,
sheet erosion, rill and gully erosion, stream and channel erosion, shoreline erosion,
landslides
What is sheet erosion? - CORRECT ANSWER- Stripping of soil that occurs due
to sheet flows of runoff
Rill and Gully Erosion - CORRECT ANSWER- 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 - CORRECT ANSWER- 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 - CORRECT
ANSWER- False: gullies are more than 75mm deep
, What factors impact rainfall erosion? - CORRECT ANSWER- 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 - CORRECT ANSWER- False
What is sediment? - CORRECT ANSWER- The eroded material suspended in
water or air
Flocculants - CORRECT ANSWER- Chemicals added to a mixture to make
suspended particles clump together.
Cationic (bad), Anionic (good)
Who decides the necessary BMPs in the SWPPP for a project? - CORRECT
ANSWER- Developer/Designer (not inspector)
Types of EC BMPs - CORRECT ANSWER- Placement of pavement, installing
landscaping materials, establishing vegetation, construction of homes,
culverts/slope drains, diversion channels, ECB and TRMs
What is the minimum number of inspections required? - CORRECT ANSWER-
Once every 14 days
Major things to look for on S&EC plans - CORRECT ANSWER- What is to be
installed before grading, as per plan
NOTES sections
Major discharge points
