activities greater than or equal to 1 acre
7. -land disturbance less than 1 ac within 1/2 miles of water body in SC costal
zone
8. NPDES permits are issued to - ANSWER ✔ operator-person or company
for a particular discharge
9. primary permittee - ANSWER ✔ -has day to day operational control to
ensure compliance with SWPP
10.-typically the owner or developer
,11.primary permittee responsibilites - ANSWER ✔ submit NOI, Preparation
of the C_SWPPP
12.Secondary permittee - ANSWER ✔ individual lot owner or residential
builder that conducts land disturbing activity limited to an individual lot or
group of lots as part of approved LCP of development
13.contractors - ANSWER ✔ must on Contractor Certification- D-0437
14.On-Site SWPPP - ANSWER ✔ SCDHEC CGP, NOI, NPDES coverage
approval letter, Contractor Certifications, Local Approvals, USACE
approvals, Critical area permit(coast)
15.OS_SWPPP - ANSWER ✔ a copy of signed and certified SWPPP, NOI,
and CGP coverage letter from DHEC must be retained at site or
electronically accessible
16.3 types of PAM - ANSWER ✔ dry/powder polyacrylamides
liquid polyacrylamides
solid/block polyacrylamides
17.Sediment control BMP's - ANSWER ✔ sediment tube ditch check
stabilized construction entrance
filter fabric inlet protection
block and gravel inlet protection
hardware fabric and stone inlet protection
pre-fabricated inlet protection
18.water surface withdrawal - ANSWER ✔ when discharging from sediment
basins, utilize outlet structures that only withdraw water from near the
waters surface within the basin, unless infeasible
19.what are the additional requirements for sediment basins - ANSWER ✔
surface water withdrawal ( skimmers or stop log risers)
Clean out stake ( 1/2 of sediment storage volume)
Public safety addressed, (as applicable)
,safety fences and signs, vector control(mosquitoes)
sediment forebays (as applicable)
Porous baffles (as applicable)
3 row minimum/ may NOT use silt fence
20.Sediment basin - ANSWER ✔ This sediment control BMP is a structure
designed to capture sediment from storm water runoff before it leaves
construction site. Basin de-watering is achieved through riser and pipe
leading to outlet on downstream side of embankment. NOTE: Near surface
withdrawal required in current CGP.
21.Installation of sediment basins - ANSWER ✔ This sediment control BMP
should be constructed before any grading takes place within drainage area.
This BMP with earthen embankments should be outfitted with de-watering
pipe and riser set just above sediment removal cutoff level. Cleanout stake
must be installed showing 1/2 sediment storage volume.
22.Sediment dam - ANSWER ✔ aka Trap. This sediment control BMP is
formed by excavating or placing earthen embankment across drainage swale.
An outlet or spillway is constructed using No. 5 washed stone and Class B
riprap aggregate.
23.Installation of sediment dam - ANSWER ✔ This sediment control BMP
specifications: 1. Upstream side of outlet should be lined with uniform 6-
inch thick layer of No. 5 stone. 2. Allow stone to extend downstream past
toe of embankment. 3. Mark sediment cleanout level of dam with stake at
1/2 sediment storage volume. 4. All areas of sediment dam should be seeded
except for bottom of basin.
24.Filter fabric inlet protection is the most appropriate BMP of choice in
situations where the flow rate is:
a. High (> 0.5 cfs)
b. Medium (~ 0.5 cfs)
c. Low (< 0.5 cfs)
d. Frequent - ANSWER ✔ c. Low (< 0.5 cfs)
, 25.Which of the following would not file a Notice of Intent (NOI) prior to any
land disturbing activities?
a. Secondary Permittee
b. Utility Provider
c. Compliance Inspector
d. Primary Permittee - ANSWER ✔ c. Compliance Inspector
26.Final site stabilization is achieved when percent vegetative cover on all
disturbed areas is at least the following:
a. 65%
b. 70%
c. 80%
d. 90% - ANSWER ✔ b. 70%
27.The sediment control structure in the center right side of the photo above is
a:
a. Rock-filter fabric inlet
b. Rock construction entrance
c. Rock ditch check
d. Rock spillway for a sediment trap - ANSWER ✔ d. Rock spillway
for a sediment trap
28.Consider the following situation: You observe bulldozer tracks with dozer
traveling parallel to the contour. The statement that you would use in an
inspection report about the situation shown is most nearly.
a. The bulldozer tracks indicate that the tracking was done in the
incorrect direction.
b. The bulldozer tracks indicate that the tracking was done in the correct
direction.
c. The situation is an improper application of tracking and should be
replaced immediately with sod.
d. ECB would not be appropriate on the site because the slope is too flat.
- ANSWER ✔ a. The bulldozer tracks indicate that the tracking was
done in the incorrect direction.
