CESSWI - BMP's
questions and
answers(already
passed)
Existing vegetation - answer a temporary or permanent BMP
designed to stabilize
soil and to remove suspended particles from sheet flow runoff.
Scheduling/Sequencing - answer temporary, procedural control that
involves
creating a written plan to address necessary BMPs and the
sequencing of
construction activities in order to mitigate the erosive effects of
wind, water,
and construction activity.
Tree protection - answer a temporary or permanent, structural BMP
that minimizes the
potential of removing or injuring those trees, which protect the soil
from the erosive
forces of wind and water through:
Leaves and branches dissipating raindrop impact forces
Roots binding soil particles together
Acting as a windbreak
Temperature control for streams.
,Bank stabilization
Hydromulch - answer stabilizing emulsion or tackifying agent,
applied with
hydraulic equipment to temporarily protect soils from the erosive
forces of
wind and water.
Hydroseeding - answer a temporary or permanent BMP that consists
of seed,
fertilizer, and stabilizing emulsion applied with hydraulic equipment
to
temporarily protect soils from the erosive forces of wind and water.
Mulching - answer a temporary, structural BMP designed to reduce
erosion and
runoff by applying straw, wood, bark, or other mulching material to
exposed
soil to dissipate the impact force of raindrops.
Temporary RECPs - answer structural BMPs, typically seen as
Erosion Control
Blankets that act as soil stabilization devices to protect disturbed
areas from
the erosive effects of water and wind. These devices are
constructed of
natural materials such as straw, wood excelsior, or coconut husk.
Permanent RECPs - answer structural BMPs, typically seen as
Erosion Control
or Turf Reinforcement Mats (more durable than blankets), that act
as soil
, stabilization devices to protect disturbed areas from the erosive
effects of
water and wind. The devices are constructed of natural materials
jute or coir,
or a synthetic material such as polypropylene
Seeding - answer a BMP
that brings about the establishment of annual (temporary) or
perennial
(permanent) vegetative cover.
Soil binders - answer A temporary, chemical BMP. Applied to
disturbed soils to reduce erosion (wind and water).
Surface roughening/scarification - answer rough texture to graded
soils. This texture forces water to encounter multiple small
"sediment traps"
as it travels down a slope, allowing for both sediment removal and
velocity
dissipation of the runoff.
Tackifiers - answer adhesives that are used to secure
mulchmaterials to a surface
and to other mulch materials, or to cause soil particles to adhere to
one
another in order to reduce erosion.
Temporary stabilization, - answer such as stone and plastic is a BMP
designed to
reduce erosion by stabilizing areas that will lay bare for extended
periods,
