Page 1 of 16
,roadway - undisturbed right of way - other similar feature- Condition along each inspected
segment are considered "representative" along that reach of construction
permittees must record rainfall events of - Answer: 0.5 inches or greater
where should rainfall records be kept - Answer: maintained in rain log located as part of the OS-
SWPPP
Inspection reports of rainfall must be - Answer: reported on each weekly inspection report and
maintained in rain log
For each compliance inspection a report must be completed and include at a minimum -
Answer: 1. Inspection date
2. Name, title, qualification of inspector
3. Weather information for period since last inspection
4.Weaher information and description of any discharges occurring at time of inspection.
5. Locations(s) of discharges of sediment or other pollutants leaving the site.
6. Location(s) of BMP's that need maintenance only.
7. Location of any BMPs that failed to operate as designed or have proven inadequate for a
particular location.
8. Location where additional BMPs are needed that did not exist at the time of inspection.
9. Corrective action required including any changes to the OS-SWPPP necessary.
10. Site name, operator name and permit identification number.

, pipe slope drain - Answer: PSD's are used when it is necessary for water to flow down slope
without causing erosion, especially before slope has been stabilized or before permanent
drainage structures are installed.
Runoff Diversion Measures INSTALLATION - Answer: Prior to swale excavation or dike building,
clear and grub all trees, brush, stumps, and other objects in path of diversion structure.
Runoff Diverson measures DESCRIPTION - Answer: Diversion dikes and berms (ridges of
compacted soil) are used to divert upslope clean water runoff from crossing areas where there
is high risk of erosion or Temporary silt ditches or swales ( excavated depressions) are used to
prevent sediment laden runoff from leaving site before being treated by sediment control BMP
Runoff Diversion inspection/maintenance - Answer: -inspect dikes and silt ditches after
specified intervals and rainfall events
-Repair damage from construction traffic and act. before end of each working day
-maintain dikes and ditches at original height or depth
-to remain effective, earth dikes must be compacted at all times
Temporary stream crossing DESCRIPTION - Answer: A temp stream crossing is typically a bridge
or culvert erected to provide safe and stable way for construction vehicle traffic to cross a
running watercourse.
-TYPICALLY ONLY USED FOR DOT PROJECTS BECAUSE THEY REQUIRE EXTRA PERMITTING(DHEC
AND OR CORPS OF ENGINEERS)
Construction De-watering DESCRIPTION - Answer: removing storm water or ground water from
bore pits, trenches, and other excavations. Usually involves pumping of water to sediment
basin, sediment trap, or geotextile filter bag.
