Definition A compost sock is a three-dimensional tubular sediment control and storm water
runoff device typically used for perimeter control of sediment and soluble
pollutants (such as phosphorous and petroleum hydrocarbon), on and around
construction activities. Compost socks trap sediment and other pollutants in
runoff water as it passes through the matrix of the sock and by allowing water to
temporarily pond behind the sock, allowing deposition of suspended solids.
Compost socks are also used to reduce runoff flow velocities on sloped surfaces.
Compost products acceptable for this application should meet the chemical,
physical and biological properties specified for Practice 6.18, Compost Blankets.
Figure 6.66a — Compost Sock
Photo Credit — Filtrexx International
Conditions Where Compost socks are to be installed down slope of disturbed areas requiring
Practice Applies erosion and sediment control. Compost socks are effective when installed
perpendicular to sheet flow, in areas where sediment accumulation of less
than six inches is anticipated. Acceptable applications include (Fifield,
2001):
• Site perimeters
• Below disturbed areas subject to sheet runoff, with minor sheet or rill
erosion. Compost socks should not be used alone below graded slopes
greater than 10 feet in height.
• Above graded slopes to serve as a diversion berm.
Rev. 5/13 6.66.1
Practice Standards and Specifications
Vegetated Compost Sock:
For permanent areas the compost sock can be directly seeded to allow vegetation
established directly on the device. Vegetation on and around the compost sock
will assist in slowing runoff velocity for increased deposition of pollutants. The
option of adding vegetation should be shown on the erosion and sedimentation
control plan. No additional soil amendments or fertilizer are required for
vegetation establishment in the vegetated compost sock.
Slope Spacing & Drainage Area:
Maximum drainage area to and spacing between the compost socks is dependent
on rainfall intensity and duration used for specific design/plan, slope steepness,
and width of area draining to the sock.
A compost sock across the full length of the slope is normally used to ensure that
stormwater does not break through at the intersection of socks placed end -to -end.
Ends are jointed together by sleeving one sock end into the other. The diameter
of the compost sock used will vary depending upon the steepness and length of
the slope; example slopes and slope lengths used with different diameter compost
socks are presented in Table 6.66b.

Material:
The compost media shall be derived from well -decomposed organic matter
source produced by controlled aerobic (biological) decomposition that has been
sanitized through the generation of heat and stabilized to the point that it is
appropriate for this particular application. Compost material shall be processed
through proper thermophilic composting, meeting the US Environmental
Protection Agency's definition for a `Process to Further Reduce Pathogens'
(PFRP), as defined at 40 CFR Part 503. The compost portion shall meet the
chemical, physical and biological properties specified in Practice 6.18, Compost
Blankets Table 6.18a, with the exception of particle size. Slightly more coarse
compost is recommended for the socks, as follows:
Particle Size Distribution
Sieve Size Percent Passing Selected Sieve Mesh Size, Dry Weight Basis
2" 99 % (3" Maximum Particle Size)
3/8" 30-50 %
See Practice 6.18, Compost Blankets for complete information on compost
parameters and tests. Installer should provide documentation to support
compliance of testing required in the compost specification.
6.66.5
• Check dams
• Along the toe of stream and channel banks
• Around area drains or inlets located in a storm drain system
• Around sensitive trees where trenching of silt fence is not beneficial for tree
survival or may unnecessarily disturb established vegetation.
• On paved surfaces where trenching of silt fence is impossible.
A compost sock can be applied to areas of sheet runoff, on slopes up to a 2:1
grade with a maximum height of 10 feet, around inlets, and in other disturbed
areas of construction sites requiring sediment control. Compost socks may also
be used in sensitive environmental areas, or where trenching may damage roots.
The weight of a filled sock (40 lbs / linear ft. for 8" diameter) effectively
prevents sediment migration beneath the sock. It is possible to drive over a
compost sock during construction (although not recommended); however, these
areas should be immediately repaired by manually moving the sock back into
place, if disturbed. Continued heavy construction traffic may destroy the fabric
mesh, reduce the dimensions, and reduce the effectiveness of the compost sock.
Vegetating the compost sock should be considered.
Planning Compost socks shall either be made on site or delivered to the j obsite
Considerations assembled. The sock shall be produced from a 5 mil thick continuous
HDPE or polypropylene, woven into a tubular mesh netting material, with
openings in the knitted mesh of - 3/8 (3-10mm). This shall then be filled with
compost meeting the specifications outlined in Practice 6.18, Compost Blankets,
with the exception of particle size, to the diameter of the sock. Compost sock
netting materials are also available in biodegradable plastics for areas where
removal and disposal are not desired (i.e., when using pre -seeded socks).
Compost socks contain the compost, maintaining its density and shape.
Compost socks should be installed parallel to the base of the slope or other
affected area, perpendicular to sheet flow. The sock should be installed a
minimum of 10 feet beyond the top of graded slopes. When runoff flows onto
the disturbed area from a land above the work zone, a second sock may be
constructed at the top of the slope in order to dissipate flows.
On locations where greater than a 200-foot long section of ground is to be treated
with a compost sock, the sock lengths should be sleeved. After one sock section
(200 feet) is filled and tied off (knotted) or zip tied, the second sock section shall
be pulled over the first 1-2 feet and 'sleeved creating an overlap. Once
overlapped, the second section is filled with compost starting at the sleeved area
to create a seamless appearance. The socks may be staked at the overlapped area
(where the sleeve is) to keep the sections together. Sleeving at the joints is
necessary because it reduces the opportunity for water to penetrate the joints
when installed in the field.
6.66.2 Rev. 5/13
6.66.6
Practice Standards and Specifications
This specification covers compost produced from various organic by-products,
for use as an erosion and sediment control measure on sloped areas. The
product's parameters will vary based on whether vegetation will be established
on the treated slope. Only compost products that meet all applicable state and
federal regulations pertaining to its production and distribution may be used in
this application. Approved compost products must meet related state and federal
chemical contaminant (e.g., heavy metals, pesticides, etc.) and pathogen limit
standards pertaining to the feedstocks (source materials) in which it are derived.
In regions subjected to higher rates of precipitation and/or greater rainfall
intensity, larger compost socks should be used. In these particular regions,
coarser compost products are preferred as the compost sock must allow for an
improved water percolation rate. The designer should check the flow rate per
foot of sock in order to ensure drainage rate of the compost sock being used is
adequate. The required flow rates are outlined in Table 6.66c.

Construction INSTALLATION
Specifications 1. Materials used in the compost sock must meet the specifications outlined
above and in Practice 6.18, Compost Blankets.
2. Compost socks should be located as shown on the erosion and sedimentation
control plan.
3. Prior to installation, clear all obstructions including rocks, clods, and other
debris greater than one inch that may interfere with proper function of the
compost sock.
4. Compost socks should be installed parallel to the toe of a graded slope, a
minimum of 10 feet beyond the toe of the slope. Socks located below flat
areas should be located at the edge of the land -disturbance. The ends of the
socks should be turned slightly up slope to prevent runoff from going around
the end of the socks.
5. Fill sock netting uniformly with compost to the desired length such that logs
do not deform.
6. Oak or other durable hardwood stakes 2" X 2" in cross section should be
driven vertically plumb, through the center of the compost sock. Stakes
should be placed at a maximum interval of 4 feet, or a maximum interval of 8
feet if the sock is placed in a 4 inch trench. See Figure 6.66b. The stakes

After filling, the compost sock must be staked in place. Oak or other durable
hardwood stakes 2"x 2" in cross section should be driven vertically plumb,
through the center of the compost sock. Stakes should be placed at a maximum
interval of 4 feet, or a maximum interval of 8 feet if the sock is placed in a 4 inch
trench. See Figure 6.66b. The stakes should be driven to a minimum depth of 12
inches, with a minimum of 3 inches protruding above the compost sock.
If the compost sock is to be left as part of the natural landscape, it may be seeded
at time of installation for establishment of permanent vegetation using the
seeding specification in the erosion and sedimentation control plan. A maximum
life of 2 years for photodegradable netting and 6 months for biodegradable
netting should be used for planning purposes.

Practice Standards and Specifications
should be driven to a minimum depth of 12 inches, with a minimum of 3
inches protruding above the compost sock.
7. In the event staking is not possible (i.e., when socks are used on pavement)
heavy concrete blocks shall be used behind the sock to hold it in place during
runoff events.
8. If the compost sock is to be left as part of the natural landscape, it may be
seeded at time of installation for establishment of permanent vegetation using
the seeding specification in the erosion and sedimentation control plan.
9. Compost socks are not to be used in perennial or intermittent streams.
Maintenance Inspect compost socks weekly and after each significant rainfall event (1/2 inch
or greater). Remove accumulated sediment and any debris. The compost sock
must be replaced if clogged or torn. If ponding becomes excessive, the sock may
need to be replaced with a larger diameter or a different measure. The sock
needs to be reinstalled if undermined or dislodged. The compost sock shall be
inspected until land disturbance is complete and the area above the measure has
been permanently stabilized.
Rev. 5/13
DISPOSAL/RECYCLING
Compost media is a composted organic product recycled and manufactured from
locally generated organic, natural, and biologically based materials. Once all soil
has been stabilized and construction activity has been completed, the compost
media may be dispersed with a loader, rake, bulldozer or similar device and may
be incorporated into the soil as an amendment or left on the soil surface to aid in
permanent seeding or landscaping. Leaving the compost media on site reduces
removal and disposal costs compared to other sediment control devices. The
mesh netting material will be extracted from the media and disposed of properly.
The photodegradable mesh netting material will degrade in 2 to 5 years if left on
site. Biodegradable mesh netting material is available and does not need to be
extracted and disposed of, as it will completely decompose in approximately 6 to
12 months. Using biodegradable compost socks completely eliminates the need
and cost of removal and disposal.
6.66.7
Compost socks may be used as check dams in ditches not exceeding 3 feet in
depth. Normally, 8 to 12 inch diameter socks should be used. Be sure to stake
the sock perpendicular to the slope of the ditch. When used as check dams,
installation should be similar to that of natural fiber wattles. The ends and
middle of the sock should be staked, and additional stakes placed at a 2-foot
maximum interval. See Table 6.66b for spacing.
Design Criteria The sediment and pollutant removal process characteristic to a compost sock
allows deposition of settling solids. Ponding occurs when water flowing to the
sock accumulates faster than the hydraulic flow through rate of the sock.
Typically, initial hydraulic flow -through rates for a compost sock are 50%
greater than geotextile fabric (silt fence). However, installation and maintenance
is especially important for proper function and performance. Design
consideration should be given to the duration of the project, total area of
disturbance, rainfall/runoff potential, soil erosion potential, and sediment loading
when specifying a compost sock.
Runoff Flow:
The depth of runoff ponded above the compost sock should not exceed the height
of the compost sock. If overflow of the device is a possibility, a larger diameter
sock should be constructed, other sediment control devices may be used, or
management practices to reduce runoff should be installed. Alternatively, a
second sock may be constructed or used in combination with Practice 6.17,
Rolled Erosion Control Products or Practice 6.18, Compost Blankets to slow
runoff and reduce erosion.
Level Contour:
The compost sock should be placed on level contours to assist in dissipating low
concentrated flow into sheet flow and reducing runoff flow velocity. Do not
construct compost socks to concentrate runoff or channel water. Sheet flow of
water should be perpendicular to the sock at impact and un-concentrated.
Placing compost socks on undisturbed soil will reduce the potential for
undermining by concentrated runoff flows.
Runoff and Sediment Accumulation:
The compost sock should be placed at a 10 foot minimum distance away from the
toe of the slope to allow for proper runoff accumulation for sediment deposition
and to allow for maximum sediment storage capacity behind the device. On flat
areas, the sock should be placed at the edge of the land -disturbance.
End Around Flow:
In order to prevent water flowing around the ends of the compost sock, the ends
of the sock must be constructed pointing upslope so the ends are at a higher
elevation. A minimum of 10 linear feet at each end placed at a 30 degree angle is
recommended.
