Minimum Standard 1 - CORRECT ANSWERS ✔✔Stabilization
|| || || || || ||
permanent or temporary soil stabilization shall be applied to denuded areas
|| || || || || || || || || ||
within seven days after final grade is reached on any portion of the site;
|| || || || || || || || || || || || || ||
temporary soil stabilization shall be applied within seven days to denuded
|| || || || || || || || || || ||
areas that may not be at final grade but will remain dormant for longer than
|| || || || || || || || || || || || || || ||
14 days; permanent stabilization shall be applied to areas that are to be left
|| || || || || || || || || || || || || ||
dormant for more than one year
|| || || || || ||
Site NOT at Final Grade - CORRECT ANSWERS ✔✔- stabilize in 14 days
|| || || || || || || || || || || ||
- temporarily seed
|| ||
- mulch
||
- permanently stabilize if dormant > 1 year
|| || || || || || ||
Site at Final Grade - CORRECT ANSWERS ✔✔- stabilize in 7 days
|| || || || || || || || || || ||
(recommended immediately)
|| ||
,- permanently or temporarily seed and mulch
|| || || || || ||
- mulch/matting/straw
||
Minimum Standard 2 - CORRECT ANSWERS ✔✔Stock Piles, Waste and
|| || || || || || || || ||
Borrow Areas
|| ||
during construction, soil stock piles and borrow areas shall be stabilized or
|| || || || || || || || || || ||
protected with sediment trapping measures
|| || || || ||
mulch prevents erosion by protecting the surface from raindrop impact and
|| || || || || || || || || ||
silt fence intercepts and detains from disturbed areas
|| || || || || || || ||
Minimum Standard 3 - CORRECT ANSWERS ✔✔Permanent Vegetation
|| || || || || || ||
permanent vegetation cover shall be established on denuded areas not
|| || || || || || || || ||
otherwise permanently stabilized (permanent vegetation shall not be
|| || || || || || || ||
considered established until a ground cover is achieved that is uniform,
|| || || || || || || || || || ||
mature enough to survive, and will inhibit erosion *there is no % associated
|| || || || || || || || || || || || ||
with this*)
|| || ||
reduce erosion and decrease sediment yield from disturbed area
|| || || || || || || ||
this is the standard used to verify that a site is ready for release of bonds or
|| || || || || || || || || || || || || || || ||
surety
||
Minimum Standard 4 - CORRECT ANSWERS ✔✔First-Step Measures
|| || || || || || ||
,Sediment basins and traps, perimeter dikes, sediment barriers and other
|| || || || || || || || ||
measures intended to trap sediment shall be constructed as a first step in any
|| || || || || || || || || || || || || ||
land-disturbing activity and shall be made functional before upslope land
|| || || || || || || || || ||
disturbance takes place
|| || ||
a certain amount of initial land disturbance may be required to provide access
|| || || || || || || || || || || ||
for equipment to install the perimeter controls, but site clearing and grading
|| || || || || || || || || || || ||
should be kept to a minimum until the perimeter controls are in place
|| || || || || || || || || || || || ||
intercepts and detains small amounts of sediment from disturbed areas
|| || || || || || || || ||
during construction operation to prevent sediment from leaving the site and
|| || || || || || || || || || ||
decrease velocity of sheet flows and low-to-moderate level channel flow
|| || || || || || || || || ||
Perimeter Controls - CORRECT ANSWERS ✔✔assures that sediment does not
|| || || || || || || || ||
leave the perimeter of the land-disturbing area once site clearing, grading,
|| || || || || || || || || || ||
and construction commences
|| || ||
Examples: silt fences, sediment traps, sediment basins, construction entrance,
|| || || || || || || ||
temporary diversions, diversions
|| || ||
Minimum Standard 5 - CORRECT ANSWERS ✔✔Earthen Structure
|| || || || || || ||
Stabilization
||
stabilization measures shall be applied to earthen structures such as dams,
|| || || || || || || || || ||
dikes, and diversions immediately after installation
|| || || || || ||
, reduce erosion and sedimentation and reduce damage from sediment and
|| || || || || || || || ||
runoff to downstream or off-site areas
|| || || || || ||
Minimum Standard 6 - CORRECT ANSWERS ✔✔Traps and Basins
|| || || || || || || ||
sediment traps and basins shall be designed and constructed based upon the
|| || || || || || || || || || ||
total drainage area (not just disturbed area) to be served by the trap or basin
|| || || || || || || || || || || || || || ||
Sediment Traps - CORRECT ANSWERS ✔✔minimum storage capacity shall be
|| || || || || || || || ||
134 cubic yards per acre of drainage area and shall only control drainage
|| || || || || || || || || || || || ||
areas less than 3 acres
|| || || || ||
*stone outlet = trap* || || ||
Sediment Basins - CORRECT ANSWERS ✔✔surface runoff from disturbed
|| || || || || || || ||
areas that is comprised of flow from drainage areas greater than or equal to 3
|| || || || || || || || || || || || || || ||
acres shall be controlled by a basin; minimum storage capacity of a sediment
|| || || || || || || || || || || || ||
basin shall be 134 cubic yards per acre of drainage area; the outfall system
|| || || || || || || || || || || || || ||
shall, at a minimum, maintain the structural integrity of the basin during a
|| || || || || || || || || || || || ||
25-year storm of 24-hour duration; runoff coefficients used in runoff
|| || || || || || || || || ||
calculations shall correspond to a bare earth condition or those conditions
|| || || || || || || || || || ||
expected to exist while the sediment basin is utilized.
|| || || || || || || || ||
Sediment Trapping Devises - CORRECT ANSWERS ✔✔1. place near the lowest
|| || || || || || || || || ||
drainage points of a project
|| || || || ||
2. install as a first-step measure [MS-4]
