The process by which eroded material is moved and deposited is called
sedimentation.
"CGP" is an acronym for "ANSWER Construction General Permit," which is
one of the NPDES permits that DHEC oversees.
When is a land disturbance permit required in a coastal county? ANSWER > or
= 1 acre or > or = 0.5 acres within 0.5 miles of a body of water
ANSWER Storm Water Pollution Prevention Plan: What Is It?
-Describes stormwater control measures - identifies possible sources of
stormwater pollution - explains how CGP will be implemented
What an SWPPP consists of: ANSWER - Permit Copy - Copy of "Notice of
Intent" (NOI) - Copy of SCDHEC Approval Letter - Construction Plans
-Inspection report -Copy of the necessary 401 certificate and 404 permission
What two documents must be included in the SWPPP in coastal zones? -
ANSWER - Critical Area Permit (if applicable) -Coastal Zone Consistency
Letter (CZC)
In a CGP, who are the three parties? ANSWER -Owner: the individual or
company that obtained the CGP
The person in charge of daily operations is known as the operator. The primary
contractor is known as the secondary operator.
What is the frequency of inspections? - ANSWER Once a month for a
temporarily stabilized area, every seven days
Is it necessary to have a rain gauge on site? ANSWER: In agreement
1. What are the two priority levels if an inspector determines that a BMP needs
maintenance or modifications?
, 2. What more has to happen? ANSWER Priority 1: Fix the problem within 48
hours (either the sediment is leaving the site or the BMP is failing).
Priority 2: Provide a remedy within seven days.
Within seven calendar days following the inspection, the resident constriction
engineer must make changes to the SWPPP.
When is it necessary to keep a Grading and Stabilization log? - ANSWER
When significant grading takes place or a graded area is left undisturbed for
more than 14 days
Which five categories of runoff control BMPs are there? ANSWER 1.
Construction dewatering 2. Runoff diversion 3. Stream crossing 4. Pipe slope
drain
Flow control and five buffers
Answer for buffer zones necessary between surface waters and damaged areas
Type and width depend on the situation.
What are the five common BMPs for erosion prevention? Surface roughening is
the first ANSWER; temporary stability is the second.
3. The use of mulch
4. ECBs, or erosion control blankets
5. TRM, or Turf Reinforcement Mat
ANSWER: Four categories of long-term BMPs 1. Complete stabilization
2. Using riprap to stabilize the channel
3. protection of outlets 4. control of dust
Three factors to be aware of when surface roughening - ANSWER Instead of
running across a slope, the dozer must run up and down it. Dozer track bumps
will cause the water to move more slowly.
2. If rills develop, they need to be regraded.
3. is carried out right away following the removal of vegetation and grading.
Temporary Stabilization: Three Important Considerations ANSWER 1. Usually,
vegetation is used. ANSWER 2. Implementation is required. If the place
remains undisturbed for 14 days
sedimentation.
