CESSWI Part 2 Exam Questions And 100% Correct
Answers A+ Graded
Hydromulch desc/purp - ANSWER temporary BMP that consists of wood/fiber in
hydraulic/tractifying mix to cover and protect soils from erosion
Hydromulch objectives - ANSWER erosion control
good housekeeping/materials mgmt
runoff control
Hydro mulch applications - ANSWER areas in need of temp stabilization
on disturbed areas to be re-disturbed
used as tackifier over other BMPs
Hydro mulch inspections - ANSWER bare sections that recieved little application
shadowed areas during application
signs of erosion
signs of pedestian or vehicle activity
signs of animal activity
application per specs in the SWPPP
Hydromulch maintennce - ANSWER reapply in areas of inadequacies
maintain un-broken coverage durin period before temporary or permanent ground
cover is established
req repair if traffic or animal acitivity
,Mulching desc/purp - ANSWER reduce erosion and runoff by applying material to
exposed soil to disipate impact force of water. reduces the velocity of runoff and helps
soil retain moisture as well as reduced temp.erature. tackifiers should be used with
mulching
mulching objectives - ANSWER erosion control
runoff control
good housekeeping/materials mgmt
mulching applications - ANSWER temporary coverage until final stabilization is achieved
Used with seeding to promote establishment of veg cover may be used with tackifiers
for increased efficiency
Mulching inspection - ANSWER Check for bare areas
Netting or other containment devices hold holes in them
Tackifier application is required, if needed
Materials moving off the installation site and into violation areas
Mulching maintenance - ANSWER Remove netting or other material to hold mulch in
place
Repair bare areas
Shall be applied/thickness shall be as ID'd in SWPPP
Add tackifier as suggested by manufacturer and as necessary due to weather
Traffic repairs
Seeding desc/purp - ANSWER temp or perm, is a bmp that brings establishment of veg
cover. will establish roots to prevent erosion
Seeding objectives - ANSWER erosion control
,post-cons mgmt
Seeding applications - ANSWER areas where no activity will occur for extended periods
areas where final stabilization is desired
Seeding Inspection - ANSWER ensure that seed is as specified in SWPPP/plan
Ensure that seedbed preparation is proper.
Ensure that seed is uniformly distributed
Efficient Mulching or blanketing
The Bare earth area where no germination has occurred
Runoff carries away seeds/Erosion
Identify flows concentration areas.
Seeding Maintenance - ANSWER Irrigate whenever necessary for germination to occur
Fertilize according to the recommendation by the manufacturer unless otherwise stated
in SWPPP/plan.
Surface roughening desc/purp - ANSWER applies a rough texture to graded soils with
mechanized equipment. texture forces water to
Surface roughening objectives - ANSWER erosion control
sediment control
runoff control
Surface roughening applications - ANSWER slopes to promote veg growth and velocity
dicipation
before rain events to minimize dust and erosion and to trap sediment
prior to leaving the job site for an extended period to aid other BMPS in event of rain
on stockpiles
, Surface roughening inspection - ANSWER process should follow the plan/swppp
indicative of rills, gullies, smoothing, or depressions
horizontally oriented grooving or depressions applied on the contour
Surface roughening maintenance - ANSWER re-treat when signs of smoothing rills or
gullies occur
seed as soon as possible to achieve perm stabilization
Baffles desc/purp ANSWER structural BMPs designed to legnthen the flow path of
basins, traps, ponds as well as slowing flow to allow pollutants time to fall out of
suspension.
May be solid, or porous.
Baffles applications - ANSWER used where runoff must be slowed to allow the receiving
basin to improve pollutant trapping
baffles objectives - ANSWER sediment control
post construction mgmt
good housekeeping/materials mgmt
baffles inspection, baffle - ANSWER inspect according to regulatory times tables
structural material integrity
Installed correctly as shown in plan / SWPP
weir width adjusted for the expected flow
sediment siltation behind baffles
trash and debris build up
baffles maintenance - ANSWER keep weir size as per plan
