CESSWI- 8 (BMPs) Exam Questions
and Answers 100% Pass
Existing vegetation - ✔✔-designed to stabilize soil and to remove suspended particles
from sheet flow runoff
Limitations= some regions may not have vegetation to work with
Scheduling - ✔✔-involves creating a written plan to address necessary BMPs and
sequencing of construction events
-must take into account local considerations such as rainfall, wind, soil types
-overall purpose is to minimize the amount and duration of exposed soil
Tree protection - ✔✔-protecting trees so they don't have to be removed
-delineate tree area with fencing or similar devices
Hydromulch - ✔✔-consists of wood or other fiber in a hydraulic matrix with a
stabilizing emulsion or tackifying agent
Limitations= requires curing time, not meant for high-traffic areas

, Hydroseed - ✔✔-consists of seed, fertilizer, and stabilizing emulsion applied with
hydraulic equipment to protect soils from wind and water
Limitations= may be difficult on steeper slopes
Mulching - ✔✔designed to reduce erosion and runoff by applying straw, wood, bark, or
other mulching material to exposed soil
Limitations= not suitable for steep slopes, undesirable species may be introduced to
your site
Rolled Erosion Control Products (RECP) - ✔✔-erosion control blankets (temp.) or turf
reinforcement mats (permanent) that act as soil stabilization devices. Constructed of
natural materials-straw, wood excelsior, or coconut husk.
Seeding - ✔✔-brings about the establishment of temporary or permanent vegetative
cover
Sod - ✔✔-operates, by laying either in squares or rolls, a thick, lush vegetative cover on
top of soil
Limitations= time from harvest to installation should not exceed two to three days; DO
NOT mow until the sod has had a chance to establish a local root system
Soil Binders - ✔✔-applied to disturbed soils to reduce erosion (ex. polyacrylamides
(PAM))
