STANDARD EROSION AND SEDIMENTATION CONTROL PLAN NOTES


General notes


1.

Only limited disturbance will be permitted to provide access to (construct
sediment traps, diversion terraces, etc.) for grading and acquiring borrow to
construct those controls.


2.

Erosion and sedimentation controls must be constructed, stabilized, and functional
before site disturbance within the tributary areas of those controls.


3.

After final site stabilization has been achieved, temporary erosion and
sedimentation controls must b
e removed. Areas disturbed during removal of the
controls must be stabilized immediately.


4.

Vehicles and equipment may neither enter directly to nor exit directly from lot
_________ onto ________. (Insert the lot numbers and road names.)


5.

At the end of ea
ch working day, any sediment tracked or conveyed onto a public
roadway will be removed and redeposited onto the construction site. Removal can

be completed through use of mechanical or hand tools, but must never be washed
off the road by use of water.


6.

Se
diment removed from E&SPC controls & facilities shall be disposed of in
landscaped areas outside of steep slopes, wetlands, floodplains or drainage swales
and immediately stabilized, or placed in topsoil stockpiles.


7.

All pumping of sediment laden water s
hall be through a dirt bag filtration device,
or equivalent sediment removal facility, over non
-
disturbed vegetated areas.
Discharge points should be established to provide for maximum distance to active
waterways.


8.

All excavation for utility line install
ation shall be limited to the amount that can
be excavated, installed, backfilled and stabilized within one working day. All
excavated material shall be deposited on the upslope side of the trench.



9.

Should unforeseen erosive conditions develop during con
struction, the contractor
shall take action to remedy such conditions and to prevent damage to adjacent
properties as a result of increased runoff and/or sediment displacement.
Stockpiles of wood chips, hay bales, crushed stone and other mulches shall be
held in readiness to deal immediately with emergency problems of erosion.


10.

The contractor is advised to become thoroughly familiar with the provisions of the
Appendix 64, Erosion Control Rules and Regulations, Title 25, Part 1,
Department of environmental
Protection, Subpart C, Protection of Natural
Resources, Article III, Water Resources, Chapter 102, Erosion Control.


11.

A copy of this erosion and sedimentation control report and plans must be posted
at the construction site.


Sediment Basin Notes
(to be in
cluded with detail)


12.

Clean out stakes must be placed at half distances from points of concentrated
inflows to temporary risers. When sediment has accumulated to clean out
elevations on any stake, it must be removed to restore basin capacities.


13.

Sedimenta
tion basins must be protected from unauthorized acts of third parties.


14.

Baffles must be installed to allow basin maintenance and clean
-
out.


15.

Approval of the use of a skimmer does not approve owner or operator use of any
skimmer in violation of any patent,

patent rights and/or patent laws.


16.

Fill material for the embankments shall be free of roots, or other woody
vegetation, organic material, large stones, and other objectionable materials. The
embankment shall be compacted in maximum ______” layered lifts
at _______%
density.


17.

Sediment basins shall be kept free of all trash, concrete wash water and other
debris that pose the potential for clogging the basin outlet structures and/or pose
the potential for pollution to Waters of the Commonwealth.


18.

A standard
note is needed with the clean out marker detail stating, “When
sediment has accumulated to the clean out elevation on any stake, all accumulated
sediment shall be removed from the entire basin bottom.”



Sediment Trap Notes
(to be included with detail)


19.

Se
diment must be removed from traps when sediment has accumulated to the
clean out elevation.


20.

Sediment traps must be protected from una
uthorized acts of third parties.


Channel Notes


21.

All channels must be kept free of obstructions such as fill ground, falle
n leaves &
woody debris, accumulated sediment, and construction materials/wastes.
Channels should be kept mowed and/or free of all weedy, brushy or woody
growth. Any underground utilities running across/ through the channel(s) shall be
immediately backfi
lled and the channel(s) repaired and stabilized per the channel
cross
-
section detail.


22.

Vegetated channels shall be constructed free of rocks, tree roots, stumps or other
projections that will impede normal channel flow a
nd/or prevent good lining to
so
i
l contact
. The channel shall be initially over
-
excavated to allow for the
placement of topsoil.


Filter Fabric Notes
(to be included with detail)


23.

Filter fabric fence must be installed at level grade. Both ends of each fence
section must extend at least
8’ upslope at 45 degrees to the main fence alignment.


24.

Sediment must be removed when accumulations reach ½ the above ground height
of the fence.


25.

Any fence section, which has been undermined or topped, must be immediately
replaced with a rock filter outl
et. (See Rock Filter Outlet Detail.)


26.

Where ends of filter fabric come together, they must be overlapped, folded and
stapled to prevent sediment bypass. The toe anchor must be backfilled and
compacted to a density equal to the surrounding soils.


Straw B
ale Barrier Notes
(to be included with detail)


27.

Straw Bale Barriers should not be used for more than 3 months.


28.

Straw Bale Barriers must be placed at level grade. Both ends of the barrier must
be extended at least 10’ upslope at 45 degrees to the main ba
rrier alignment.


29.

Sediment must be removed when accumulations reach 1/3 the above ground
height of the barrier.


30.

Any section of straw bale barrier, which has been undermined or topped, must be
immediately replaced with a rock filter outlet. (See rock filt
er outlet detail.)


Storm Sewer Inlet Notes


31.

Stormwater inlets, which do not discharge to sediment traps or basins, must be
protected until the tributary areas are stabilized.


32.

Sediment must be removed from inlet protection after each storm event, or when
the distance between the grate and the sediment level is reduced to 18”.


Stabilization notes


33.

Stockpile heights must not exceed 35’. Stockpile slopes must be 2:1 or flatter.


34.

Upon completion of an earth disturbance activity or any stage or phase of an
ac
tivity, the operator shall stabilize immediately the disturbed areas to protect
from accelerated erosion. During non
-
germinating periods, mulch must be
applied at the specified rates. Disturbed areas which are not at finished grade and
which will be redi
sturbed within 1 year may be stabilized in accordance with
temporary seeding specifications. Disturbed areas, which are either at finished
grade or will not be redisturbed within 1 year, must be stabilized in accordance
with permanent seeding specificatio
ns.


35.

Diversion channels, sedimentation basins, sediment traps, and stockpiles must be
stabilized immediately.


36.

Hay or straw mulch must be applied at rates of at least 3.0 tons per acre.


37.

Until the site has achieved final stabilization the owner and/or cont
ractor shall
properly implement, operate and maintain all the best management practices.
Maintenance shall include inspections of all erosion and sedimentation control
after each runoff event and on a weekly basis. All preventative and remedial
maintenan
ce work, including clean out, repair, replacement, regrading, reseeding,
remulching, and renetting, must be performed immediately.


38.

An area shall be considered to have achieved final stabilization when it has a
minimum of 70% uniform perennial vegetative c
over or other permanent non
-
vegetative cover with a density sufficient to resist accelerated surface erosion and
subsurface characteristics sufficient to resist sliding or other movements.


39.

Mulch with mulch control netting or erosion control blankets must
be installed on
all slopes greater than 3:1.


Stream Crossing Notes


40.

At stream crossings, 50’ stream bank buffer areas should be maintained. On
buffers, clearing, sod disturbances, excavation, and equipment traffic should be
minimized. Activities such as

stacking cut logs, burning cleared brush,
discharging rainwater from trenches, welding pipe sections, refueling and
maintaining equipment should be accomplished outside of buffers.

(to be included with detail)


43.

Rock construction entrance thickness
will be constantly maintained to the
specified dimensions by adding rock. A stockpile of rock material will be
maintained on the site for this purpose. At the end of each construction day, all
sediment deposited on public roadways will be removed and ret
urned to the
construction site.
