SOUTH BURLINGTON, VT
E-001 EC SheetIntroduction
This project is subject to the terms and conditions of the authorization
from the State of Vermont to discharge construction related storm water
runoff.
Coverage under the State Construction General Permit 3-9020 is
required for any construction activity that disturbs 1 or more acres of
land, or is part of a larger development plan that will disturb 1 or more
acres.
This project has been deemed to qualify as a Low Risk Site which is
subject to the erosion prevention and sediment control (EPSC)
standards set for in the State of Vermont's
Low Risk Site Handbook for Erosion Prevention and Sediment
Control
The following narrative and implementation requirements represent the
minimum standard for which this site is required to be maintained as
regulated by the State of Vermont.
Any best management practices (BMP's) depicted on the project's EPSC
Site plan which go beyond the Handbook requirements are considered
to be integral to the management of the site and represent components
of the municipal EPSC approval for the project which shall be
implemented.
The EPSC plan depicts one snap shot in time of the site. All
construction sites are fluid in their day to day exposures and risks as it
relates to minimizing sediment loss from the site. It is the
responsibility of the Contractor to implement the necessary BMP's
to comply with the Low Risk Handbook standards outlined on this
sheet based on the interim site disturbance conditions which may or
may not be shown on the EPSC Site Plan.
Specific BMP's which are critical to allowing the project to be considered
a Low risk site include the items checked below:
x Limit the amount of disturbed earth to two acres or less at any one
time.
x There shall be a maximum of 7 consecutive days of disturbed earth
exposure in any location before temporary or final stabilization is
implemented.
1. Mark Site Boundaries
Purpose:
Mark the site boundaries to identify the limits of construction. Delineating
your site will help to limit the area of disturbance, preserve existing
vegetation and limit erosion potential on the site.
How to comply:
Before beginning construction, walk the site boundaries and flag trees,
post signs, or install orange safety fence. Fence is required on any
boundary within 50 feet of a stream, lake, pond or wetland, unless the
area is already developed (existing roads, buildings, etc.)
2. Limit Disturbance Area
Purpose:
Limit the amount of soil exposed at one time to reduce the potential
erosion on site.
Requirements:
The permitted disturbance area is specified on the site's written
authorization to discharge. Only the acreage listed on the authorization
form may be exposed at any given time.
How to comply:
Plan ahead and phase the construction activities to ensure that no more
than the permitted acreage is disturbed at one time. Be sure to properly
stabilize exposed soil with seed and mulch or erosion control matting
before beginning work in a new section of the site.
3. Stabilize Construction Entrance
Purpose:
A stabilized construction entrance helps remove mud from vehicle
wheels to prevent tracking onto streets.
Requirements:
If there will be any vehicle traffic off of the construction site, you must
install a stabilized construction entrance before construction begins.
How to install
Rock Size: Use a mix of 1 to 4 inch stone
Depth: 8 inches minimum
Width: 12 feet minimum
Length: 40 feet minimum (or length of driveway, if shorter)
Geotextile: Place filter cloth under entire gravel bed
Maintenance:
Redress with clean stone as required to keep sediment from tracking
onto the street.
4. Install Silt Fence
Purpose:
Silt fences intercept runoff and allow suspended sediment to settle out.
Requirements:
Silt fence must be installed:
x on the downhill side of the construction activities
x between any ditch, swale, storm sewer inlet, or waters of the State
and the disturbed soil
* Hay bales must not be used as sediment barriers due to their
tendency to degrade and fall apart.
Where to place:
x Place silt fence on the downhill edge of bare soil. At the bottom of
slopes, place fence 10 feet downhill from the end of the slope (if
space is available).
x Ensure the silt fence catches all runoff from bare soil.
x 0D[LPXPGUDLQDJHDUHDLVõDFUHIRUIHHWRIVLOWIHQFH
x Install silt fence across the slope (not up and down hills!)
x Install multiple rows of silt fence on long hills to break up flow.
x Do not install silt fence across ditches, channels, or streams or in
stream buffers.
How to install silt fence:
x Dig a trench 6 inches deep across the slope
x Unroll silt fence along the trench
x Ensure stakes are on the downhill side of the fence
x Join fencing by rolling the end stakes together
x Drive stakes in against downhill side of trench
x Drive stakes until 16 inches of fabric is in trench
x Push fabric into trench; spread along bottom
x Fill trench with soil and pack down
Maintenance:
x Remove accumulated sediment before it is halfway up the fence.
x Ensure that silt fence is trenched in ground and there are no gaps.
5. Divert Upland Runoff
Purpose:
Diversion berms intercept runoff from above the construction site and
direct it around the disturbed area. This prevents clean water from
becoming muddied with soil from the construction site.
Requirements:
If storm water runs onto your site from upslope areas and your site
meets the following two conditions, you must install a diversion berm
before disturbing any soil.
1.You plan to have one or more acres of soil exposed at any one time
(excluding roads).
2.Average slope of the disturbed area is 20% or steeper.
How to install:
1.Compact the berm with a shovel or earth-moving equipment.
2.Seed and mulch berm or cover with erosion control matting
immediately after installation.
3.Stabilize the flow channel with seed and straw mulch or erosion
control matting. Line the channel with 4 inch stone if the channel
slope is greater than 20%.
4.Ensure the berm drains to an outlet stabilized with riprap. Ensure that
there is no erosion at the outlet.
5.The diversion berm shall remain in place until the disturbed areas are
completely stabilized.
6. Slow Down Channelized Runoff
Purpose:
Stone check dams reduce erosion in drainage channels by slowing
down the storm water flow.
Requirements:
If there is a concentrated flow (e.g. in a ditch or channel) of storm water
on your site, then you must install stone check dams. Hay bales must
not be used as check dams.
How to install:
Height: No greater than 2 feet. Center of dam should be 9 inches lower
than the side elevation
Side slopes: 2:1 or flatter
Stone size: Use a mixture of 2 to 9 inch stone
Width: Dams should span the width of the channel and extend up the
sides of the banks
Spacing: Space the dams so that the bottom (toe) of the upstream dam
is at the elevation of the top (crest) of the downstream dam. This
spacing is equal to the height of the check dam divided by the channel
slope.
Spacing (in feet) = Height of check dam (in feet)/Slope in channel (ft/ft)
Maintenance:
Remove sediment accumulated behind the dam as needed to allow
channel to drain through the stone check dam and prevent large flows
from carrying sediment over the dam. If significant erosion occurs
between check dams, a liner of stone should be installed.
7. Construct Permanent Controls
Purpose:
Permanent storm water treatment practices are constructed to maintain
water quality, ensure groundwater flows, and prevent downstream
flooding. Practices include detention ponds and wetlands, infiltration
basins, and storm water filters.
Requirements:
If the total impervious* area on your site, or within the common plan of
development, will be 1 or more acres, you must apply for a State Storm
water Discharge Permit and construct permanent storm water treatment
practices on your site. These practices must be installed before the
construction of any impervious surfaces.
How to comply:
Contact the Vermont Storm water Program and follow the requirements
in the Vermont Storm water Management Manual. The Storm water
Management Manual is available at:
www.vtwaterquality.org/stormwater.htm
*An impervious surface is a manmade surface, including, but
not limited to, paved and unpaved roads, parking areas, roofs,
driveways, and walkways, from which precipitation runs off rather
than infiltrates.
8. Stabilize Exposed Soil
Purpose:
Seeding and mulching, applying erosion control matting, and
hydroseeding are all methods to stabilize exposed soil. Mulches and
matting protect the soil surface while grass is establishing.
Requirements:
All areas of disturbance must have temporary or permanent stabilization
within 7, 14, or 21 days of initial disturbance, as stated in the project
authorization. After this time, any disturbance in the area must be
stabilized at the end of each work day.
The following exceptions apply:
x Stabilization is not required if earthwork is to continue in the area
within the next 24 hours and there is no precipitation forecast for
the next 24 hours.
x Stabilization is not required if the work is occurring in a
self-contained excavation (i.e. no outlet) with a depth of 2 feet or
greater (e.g. house foundation excavation, utility trenches).
All areas of disturbance must have permanent stabilization within 48
hours of reaching final grade.
How to comply:
Prepare bare soil for seeding by grading the top 3 to 6 inches of soil and
removing any large rocks or debris.
Seeding Rates for Temporary Stabilization
April 15 - Sept. 15 --- Ryegrass (annual or perennial: 20 lbs/acre)
Sept. 15 - April 15 --- Winter rye: 120 lbs/acre
Seeding Rates for Final Stabilization:Choose
Mulching Rates
April 15 - Sept.15 -- Hay or Straw: 1 inch deep (1-2 bales/1000 s.f.)
Sept.15 - April 15 -- Hay or Straw: 2 in. deep (2-4 bales/1000 s.f.)
Erosion Control Matting
As per manufacturer's instructions
Hydroseed
As per manufacturer's instructions
9. Winter Stabilization
Purpose:
Managing construction sites to minimize erosion and prevent sediment
loading of waters is a year-round challenge. In Vermont, this challenge
becomes even greater during the late fall, winter, and early spring
months.
'Winter construction' as discussed here, describes the period between
October 15 and April 15, when erosion prevention and sediment control
is significantly more difficult.
Rains in late fall, thaws throughout the winter, and spring melt and rains
can produce significant flows over frozen and saturated ground, greatly
increasing the potential for erosion.
Requirements for Winter Shutdown:
For those projects that will complete earth disturbance activities prior to
the winter period (October 15), the following requirements must be
adhered to:
1.For areas to be stabilized by vegetation, seeding shall be completed
no later than September 15 to ensure adequate growth and cover.
2.If seeding is not completed by September 15, additional
non-vegetative protection must be used to stabilize the site for the
winter period. This includes use of Erosion Control Matting or netting
of a heavy mulch layer. Seeding with winter rye is recommended to
allow for early germination during wet spring conditions.
3.Where mulch is specified, apply roughly 2 inches with an 80-90%
cover. Mulch should be tracked in or stabilized with netting in open
areas vulnerable to wind.
Requirements for Winter Construction
If construction activities involving earth disturbance continue past
October 15 or begin before April 15, the following requirements must be
adhered to:
1.Enlarged access points, stabilized to provide for snow stockpiling.
2.Limits of disturbance moved or replaced to reflect boundary of winter
work.
3.A snow management plan prepared with adequate storage and
control of meltwater, requiring cleared snow to be stored down slope
of all areas of disturbance and out of storm water treatment structures.
4.A minimum 25 foot buffer shall be maintained from perimeter controls
such as silt fence.
5.In areas of disturbance that drain to a water body within 100 feet, two
rows of silt fence must be installed along the contour.
6.Drainage structures must be kept open and free of snow and ice
dams.
7.Silt fence and other practices requiring earth disturbance must be
installed ahead of frozen ground.
8.Mulch used for temporary stabilization must be applied at double the
standard rate, or a minimum of 3 inches with an 80-90% cover.
9.To ensure cover of disturbed soil in advance of a melt event, areas of
disturbed soil must be stabilized at the end of each work day, with the
following exceptions:
x If no precipitation within 24 hours is forecast and work will resume
in the same disturbed area within 24 hours, daily stabilization is not
necessary.
x Disturbed areas that collect and retain runoff, such as house
foundations or open utility trenches.
10.Prior to stabilization, snow or ice must be removed to less than 1
inch thickness.
11.Use stone to stabilize areas such as the perimeter of buildings
under construction or where construction vehicle traffic is anticipated.
Stone paths should be 10 to 20 feet wide to accommodate vehicular
traffic.
10. Stabilize Soil at Final Grade
Purpose:
Stabilizing the site with seed and mulch or erosion control matting when
it reaches final grade is the best way to prevent erosion while
construction continues.
Requirements:
Within 48 hours of final grading, the exposed soil must be seeded and
mulched or covered with erosion control matting.
How to comply:
Bring the site or sections of the site to final grade as soon as possible
after construction is completed. This will reduce the need for additional
sediment and erosion control measures and will reduce the total
disturbed area.
For seeding and mulching rates, follow the specifications under Rule 8,
Stabilizing Exposed Soil.
11. Dewatering Activities
Purpose:
Treat water pumped from dewatering activities so that it is clear when
leaving the construction site.
Requirements:
Water from dewatering activities that flows off of the construction site
must be clear. Water must not be pumped into storm sewers, lakes, or
wetlands unless the water is clear.
How to comply:
Using sock filters or sediment filter bags on dewatering discharge hoses
or pipes, discharge water into silt fence enclosures installed in vegetated
areas away from waterways. Remove accumulated sediment after the
water has dispersed and stabilize the area with seed and mulch.
12. Inspect Your Site
Purpose:
Perform site inspections to ensure that all sediment and erosion control
practices are functioning properly. Regular inspections and maintenance
of practices will help to reduce costs and protect water quality.
Requirements:
Inspect the site at least once every 7 days and after every rainfall or
snow melt that results in a discharge from the site. Perform maintenance
to ensure that practices are functioning according to the specifications
outlined in this handbook.
In the event of a noticeable sediment discharge from the construction
site, you must take immediate action to inspect and maintain existing
erosion prevention and sediment control practices. Any visibly
discolored storm water runoff to waters of the State must be reported.
Forms for reporting discharges are available at:
www.vtwaterquality.org/stormwater.htm
