Colonial Pipeline Company — Greensboro Junction WWTF
Wastewater Irrigation System
Mr. Mega:
Phone: [phone]
e-mail: [e-mail]
Colonial Pipeline Company (CPC) submitted a Request for Minor Permit Modification to the North Carolina
(NC) Department of Environmental Quality (DEQ) on April 30, 2023 associated with the Greensboro Junction
Wastewater Treatment Facility (VW TF), Wastewater Irrigation System (WWIS), Non -Discharge Permit No.
WQ0006317. The NC DEQ asked for additional information in a letter dated June 12, 2023. CPC
subsequently submitted a request for an additional 14-days to provide the additional information on July 6,
2023, which was approved on July 7, 2023 by email.
CPC is planning for construction activities that will require modifications to the existing WWIS permit. CPL
requested the following:
• Removal of Zone 1 (1.09 acres)
• Removal of Monitoring Wells MW-1, MW-2, and MW-6
The NC DEQ's requests are provided below, followed by CPC's responses.
1. Please provide a closure plan for the removal of Zone 1. This closure plan should include, but
not be limited to demolition, erosion and sedimentation control, and site restoration. More
detail should be provided about the irrigation piping/spray head abandonment and pipe
capping process.
The final permit will include a compliance schedule that requires a North Carolina licensed
Professional Engineer to provide an Engineering Certification for the proper closure of Zone
1 after construction is complete.
A closure plan for the removal of Zone 1 is included as Attachment 1.
2. Is there potential for the removal of the Zone 1 irrigation piping to raise the PSI in the
remaining irrigation piping for Zones 2 and 3 past their rated capacity? If so, please provide
calculations showing the capacity is not exceeded.
The spray irrigation procedures historically implemented at the facility have been to spray to the
at
1000 Lake Street Alpharetta, Georgia 30009 1 www.colpipe.com

(a Colonial Pipeline Company
zones in pairs. Further, Zone 1 has not been used since November 2021 and since then, Zones 2
and 3 have been operated together. Therefore, the removal of Zone 1 will not impact how the spray
irrigation system has been historically operated and will not impact the PSI typically present when the
system is operated.
3. Please confirm the linear feet of the 3-inch distribution force main, the linear feet of the 4-inch
force main, and the number of spray heads to be removed so the facility description in the
final permit can be updated accordingly.
Based on as-builts during the construction of the spray fields, Zone 1 is comprised of approximately
802 feet of 3-inch force main. Spray heads 1 through 5 will be removed. Please note that spray head
6 was previously removed. Zone 2 will continue to include spray heads 7 through 11 and Zone 3 will
continue to include spray heads 12 through 17.
4. Caitlin Caudle of the Winston-Salem Regional Office noted in her Staff Report that wastewater
with a sodium adsorption ratio (SAR) of greater than 30 has been infrequently irrigated since
March 2020 at this facility. Permittees that irrigate wastewater with a SAR of 10 or higher are
required to obtain recommendations from the local Cooperative Extension Office, the
Department of Agriculture and Consumer Services, the Natural Resource Conservation
Service, a North Carolina Licensed Soil Scientist, or an agronomist. The recommendations
shall address the sodium application rate, soil amendments (e.g., gypsum, etc.), or a
mechanism for maintaining site integrity and conditions conducive to crop growth. Please
provide recommendations from one of the entities listed above that addresses the high SAR
wastewater being irrigated at this facility.
Willcox & Mabe Soil Solutions, PLLC of Summerfield, NC has prepared recommendations to
maintain site integrity and conditions conducive to crop growth, which are included as Attachment 2.
CPC appreciates your assistance with this minor permit modification request. If there is any further
information required or questions regarding this request please do not hesitate to contact me at (678) 213-
7365.
Sincerely,
Colonial Pipeline Company

1.0 INTRODUCTION
Colonial Pipeline Company (CPC) submitted a Request for Minor Permit Modification to the North Carolina
(NC) Department of Environmental Quality (DEQ) on April 30, 2023 associated with the Greensboro Junction
Wastewater Treatment Facility (VW TF), Wastewater Irrigation System (VVV\AS), Non -Discharge Permit No.
WQ0006317. CPC is planning for construction activities that will require modifications to the existing WWIS
permit. CPC requested the following:
• Removal of Zone 1 (1.09 acres)
• Removal of Monitoring Wells MW-1, MW-2, and MW-6
The NC DEQ asked for additional information in a letter dated June 12, 2023. In the letter, the NC DEQ
requested a closure plan for the removal of Zone 1 that would include, but not be limited to, demolition;
erosion and sedimentation control; and site restoration. The NC DEQ also requested that more detail should
be provided about the irrigation piping/spray head abandonment and pipe capping process. Lastly, the NC
DEQ stated that the final permit will include a compliance schedule that requires a NC licensed Professional
Engineer to provide an Engineering Certification for the proper closure of Zone 1 after construction is
complete.
2.0 DEMOLITION
CPC proposes that the Zone 1 irrigation system will be decommissioned by removing the Zone 1 piping. The
valve that directs water to Zone 1 will be removed and replaced with an end cap that will be welded on. The
spray heads will be removed and stored as replacement parts for Zones 2 and 3. The 802 feet of 3-inch pipe
will be excavated and properly disposed of.
3.0 EROSION AND SEDIMENT CONTROL
The excavation and removal of the pipe from Zone 1 will cause less than a quarter acre of disturbance.
However, the excavation and removal of the pipe will be performed as part of a larger construction project
to construct one or more butane spheres in the Zone 1 area, as shown on the proposed Site Plan drawing
(7-GBJ-P2 Sheet 8). Therefore, the decommissioning of Zone 1 is included in the proposed Erosion and
Sediment Control Plan for the construction project. Select drawings from the proposed Erosion and
Sediment Control Plan are attached (7-GBJ-P7 Sheets 1, 7, 11-16, 18, and 20-28). Please note that the
designs may be modified and the proposed plans will be modified accordingly.
4.0 SITE RESTORATION
As discussed above, one or more butane sphere are proposed to be constructed at the Zone 1 location
after the removal of the irrigation piping. Any area outside of the construction area will be returned to
original grade and seeded. The remaining area will be seeded or graveled based on its proposed use
after construction.
5.0 ENGINEERING CERTIFICATION
Upon completion, a NC licensed engineer will certify that the decommissioning of Zone 1 was performed in
accordance with this Closure Plan.
6.0 CONCLUSION
This Closure Plan has been prepared to address the requests from the June 12, 2023 letter from the NC
DEQ, which requested a closure plan for the removal of Zone 1 that would include, but not be limited to,
1000 Lake Street Alpharetta, Georgia 30009 1 www.colpipe.com

(a Colonial Pipeline Company
demolition; erosion and sedimentation control; and site restoration. The NC DEQ also requested that more
detail should be provided about the irrigation piping/spray head abandonment and pipe capping process.

CONTROL MANUAL
4.3.1 Temporary Silt Fence
(1605.01)
Prior tc installing the salt fence, a trench needs to be excavated so that the geotextile can be buried with compacted
soil or gravel backfill. Thorough compaction of the backfill is critical to the performance of the silt fence. Temporary
silt fence can be installed with or without a woven wire backing. Periodic inspections and maintenance of the fence
will need to be done, especially after each rainfall.
Technician's Checklist
* The silt fence should be installed in accordance with the Erosion and Sediment Control Plans.
In order for the silt fence to be effective, it is essentW to verify that the geotextile is buried in an excavated
trench.
• In addition to the geotextile being buried, it should be adequately buried tivith compacted soil backfill to
secure the silt fence and keep ;t in place.
• The silt fence should be inspected for sediment accumulation and repairs on a regular basis and after
significant rain events.
Measurement & Payment
VVhen the accumulated silt is removed along the silt fence, it is paid for as "Silt Excavation."
Pay Iterns Pay Units
Temporary Silt Fence Linear Foot
Seeding and Mulching Acre
Silt Excavation Cubic Yard
Maintenance
r Inspect the silt fence on a regular basis and after each
significant rainfall. Make any repairs immediately.
• e �
* Inspect the silt fence to be sure the bottom of the
geotextile is keyed in properly.
■ At a minimum, remove and dispose of all silt - - - . •
accumulations when depth reaches i}z the height of the
geotextile. Do not undermine the fence during _
cleanout.
• Dispose of sediment by hauling it to an approved waste
site with appropriate perimeter protection.
• Remove and replace deteriorated or clogged silt fence.
• Replace silt fence removed for access at the end of each day's operation.
• Install additional pasts or wire backing if fence is sagging.

Note; .After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable against accelerated erosion until permanent ,round stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground' sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
Temporary Stabilizatlan Permanent Stabilization
• Terriporary grass seed covered with straw or • Permanent grass seed covered with straw or
l other mulches and tackifiers other mulches and tackifiers
• Hydroseeding * Geotextiie fabrics such as permanent sail
• Rolled erosion control products with or reinforcernent mattill
without temporary grass seed • Hydroseedin,g
• Apl)ropriately applied straw or other mulch • Shrubs or other permanent plantings covered
• Plastic sheeting With mulch

waters unless no other alternatives are reasonably available.
4- Locate waste containers on areas that do not receive substantial amounts of runoff
from upland areas ,and does not drain directly to a storm drain, stream or wetland.
Cover waste containers at the end of each workday and before storm events or
provide secondary containment. Repair or replace damaged waste containers.
6. Anchor all lightweight items in waste containers during times of high winds.
�'. Empty waste containers as needed to prevent overflow. Clean up immediately if
containers overflow.
R. Dispose waste off -site at an approved disposal facility.
9. On business days, clean up and dispose of waste in designated waste containers.
PAINT AND OTHER LIQUID WASTE
1. Igo not dump paint and other liquid waste into storm drains, streams or wetlands.
2. Locate paint washouts at least 50 feet array from storm drain inlets and surface
waters unless no rather alternatives are reasonably available.
3. Contain liquid wastes in a controlled area.
4. Containment must be labeled, sized and placed appropriately for the needs of site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from
construction sites,
PORTABLE TOILETS
1. Inst�adl portable toilets on level ground, at least 50 feet array from storm drains,
strearms or wetlands unless there is no alternative reasonably available. if 50 foot
offset is not attainable, provide relocation of portable toilet behind silt fence or place
on a gravel pad and surround with sand bags_
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot traffic areas.
3. Monitor portable toilets for leaking, and properly dispose of any leaked material.
Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace
with properly operating unit.

1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least
50 feet away from storm drain inlets, sediment basins, perimeter sediment controls
and surface waters unless it can be shown no ether alternatives are reasonably
available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of
five feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance
with the approved plan and any additional requirements. Soil stabilization is defined
as vegetative, physical or chemical coverage techniques that will restrain accelerated

6.64 SKIMMER SEDIMENT BASIN
Definition An earthen embankment suitably located to capture runoff, with a trapezoidal
S B ST spillway lined with an impermeable geotextile or laminated plastic membrane,
and equipped with a floating skimmer for dewatering.
Purpose Sediment basins are designed to provide an area for runoff to pool and settle
out a portion of the sediment carried down gradient. Past designs used a
perforated riser for dewatering, which allowed water to leave the basin from
all depths. One way to improve the sediment capture rate is to have an outlet
which dewaters the basin from the top of the water column where the water
is cleanest. A skimmer is probably the most common method to dewater a
sediment basin from the surface. The basic concept is that the skimmer does
not dewater the basin as fast as runoff enters it, but instead allows the basin
to fill and then slowly drain over hours or days. This process has two effects.
First, the sediment in the runoff has more time to settle out prior to discharge.
Second, a pool of water forms early in a storm event and this further increases
sedimentation rates in the basin. Many of the storms will produce more
volume than the typical sediment basin capacity and flow rates in excess of
the skimmer capability, resulting in flow over the emergency spillway. This
water is also coming from the top of the water column and has thereby been
"treated" to remove sediment as much as possible. (Adapted from SoilFacts:
Dewatering Sediment Basins Using Surface Outlets. N. C. State University,
Soil Science Department.)
Conditions Where Skimmer sediment basins are needed where drainage areas are too large
Practice Applies
for temporary sediment traps. Do not locate the skimmer sediment basin in
intermittent or perennial streams.
Planning Select locations for skimmer basins during initial site evaluation. Install
Considerations skimmer sediment basins before any site grading takes place within the
drainage area.
Select skimmer sediment basin sites to capture sediment from all areas that are
not treated adequately by other sediment control measures. Always consider
access for cleanout and disposal of the trapped sediment. Locations where
a pond can be formed by constructing a low dam across a natural Swale are
generally preferred to sites that require excavation. Where practical, divert
sediment -free runoff away from the basin.
A skimmer is a sedimentation basin dewatering control device that withdraws
water from the basin's water surface, thus removing the highest quality water
for delivery to the uncontrolled environment. A skimmer is shown in Figure
6.64a. By properly sizing the skimmer's control orifice, the skimmer can be
made to dewater a design hydrologic event in a prescribed period. Because the
spillway is actually used relatively frequently, it should be carefully stabilized
using geotextiles, or rock if necessary, that can withstand the expected flows.
The spillway should be placed as far from the inlet of the basin as possible to
maximize sedimentation before discharge. The spillway should be located in
natural groundcover to the greatest extent possible

Minimum Surface Area: 325 square feet per cfs of Qlo peak inflow
Minimum L/W Ratio: 2:1
Maximum L/W Ratio: 6:1
Minimum Depth: 2 feet
Dewatering Mechanism: Skimmer
Minimum Dewatering Time: 2 days
Baffles Required: 3 baffles*
(*Note: Basins less than 20 feet in length may use 2 baffles.)
Drainage areas —Limit drainage areas to 10 acres.
Design basin life —Ensure a design basin life of 3 years or less.
Dam height —Limit dam height to 5 feet.
Basin locations —Select areas that:
• Provide capacity for storage of sediment from as much of the planned
disturbed area as practical;
• Exclude runoff from undisturbed areas where practical;
• Provide access for sediment removal throughout the life of the project;
• Interfere minimally with construction activities.
Basin shape —Ensure that the flow length to basin width ratio is at least 2:1
to improve trapping efficiency. Length is measured at the elevation of the
principal spillway.
Storage volume —Ensure that the sediment storage volume of the basin, as
measured to the elevation of the crest of the principal spillway, is at least
1,800 cubic feet per acre for the disturbed area draining into the basin (1,800
cubic feet is equivalent to half an inch of sediment per acre of basin disturbed
area).
Remove sediment from the basin when approximately one-half of the storage
volume has been filled.
Spillway capacity —The spillway system must carry the peak runoff from
the 10-year storm with a minimum 1 foot of freeboard in the spillway. Base
runoff computations on the disturbed soil cover conditions expected during
the effective life of the structure.
Sediment cleanout elevation —Determine the elevation at which the invert of
the basin would be half -full. This elevation should also be marked in the field
with a permanent stake set at this ground elevation (not the top of the stake).

The costs of using a skimmer system are similar, or occasionally less, than
a conventional rock outlet or perforated riser. However, the basin is more
efficient in removing sediment. Another advantage of the skimmer is that it
can be reused on future projects. The main disadvantage of the skimmer is
that it does require frequent maintenance, primarily in removing debris from
the inlet.
A skimmer must dewater the basin from the top of the water surface. The rate
of dewatering must be controlled. A dewatering time of 2-5 days is required.
Any skimmer design that dewaters from the surface at a controlled rate
is acceptable.

Basin dewatering—The basin should be provided with a surface outlet. A
floating skimmer should be attached to a Schedule 40 PVC barrel pipe of the
same diameter as the skimmer arm. The orifice in the skimmer will control
the rate of dewatering. The skimmer should be sized to dewater the basin in
2-5 days).
Outlet Protection —Discharge velocities must be within allowable limits for
the receiving stream (References: Outlet Protection).
Basin spillway —Construct the entire flow area of the spillway in undisturbed
soil if possible. Make the cross section trapezoidal with side slopes of 3:1 or
flatter.
• Capacity —The minimum design capacity of the spillway must be the peak
rate of runoff from the 10-year storm. Maximum depth of flow during the
peak runoff should be 6 inches. In no case should the freeboard of the
spillway be less than 1 foot above the design depth of flow.
• Velocity —Ensure that the velocity of flow discharged from the basin
is nonerosive for the existing conditions. When velocities exceed that
allowable for the receiving areas, provide outlet protection (References:
Outlet Protection).
Embankment —Ensure that embankments for skimmer sediment basins do
not exceed 5 feet in height (measured at the center line from the original
ground surface to the top of the embankment). Keep the crest of the spillway
outlet a minimum of 1.5 feet below the top of the embankment. Additional
freeboard may be added to the embankment height which allows flow through
a designated bypass location. Construct embankments with a minimum
top width of 5 feet and side slopes of 2:1 or flatter. Machine compact the
embankments.
Excavation —Where sediment pools are formed or enlarged by excavation,
keep side slopes at 2:1 or flatter for safety.
Erosion protection —Stabilize all areas disturbed by construction (except
the lower half of the sediment pool) by suitable means immediately after
completing the basin (References: Surface Stabilization).
Trap efficiency —Improve sediment basin trapping efficiency by employing
the following considerations in the basin design:
• Surface areaIn the design of the settling pond, allow the largest surface
area possible.
• Length —Maximize the length -to -width ratio of the basin to prevent short
circuiting, and ensure use of the entire design settling area.
• Baffles —Provide a minimum of three porous baffles to evenly distribute
flow across the basin and reduce turbulence.
• Inlets —Area between the sediment inlets and the basin should be stabilized
by geotextile material, with or without rocks (Figure 6.64c shows the area
with rocks). The inlet to basin should be located the greatest distance
possible from the principal spillway.

SKIMMER ORIFICE DIAMETER
The orifice of a skimmer should be selected in order to achieve the desired
dewatering time. Three days is probably the optimal length oftime for temporary
sediment controls. It allows longer settling time for suspended solids remaining
in the basin after a storm event, while dewatering the basin in less time than
the average interval between rainfall events. Design criteria for permanent
stormwater detention basins in the Division of Water Quality Stormwater BMP
Manual require 2-5 days for dewatering.
Procedure
First determine the desired dewatering time in days (td) and the volume (V) of
water to be released in that time period. Dividing the volume in cubic feet by the
dewatering time in days gives a flow rate Qd in cubic feet per day.
Qd = V / td (ft'/day)
Next determine the head on the skimmer orifice. Table 6.64a has the values for
various sizes of the Faircloth skimmer.

The desired orifice diameter (D) in inches can now be calculated using the
equation
D V Qd /(2310 * V H) (inches)
Example: Select a skimmer that will dewater a 20,000 ft' skimmer basin in 3
days.
1. Qd = V / td (ft3/day) = 20,000 ft3 / 3 days = 6670 (W/day).
2. Try a 4 inch skimmer, with H = 0.333 ft. (Table 6.64a)
3. D = V Qd /(2310 * V H) (in.) = V 6670 ft3/day /(2310 * OV 333 ft.) (in.)
= 2.24 inches (Use 2 I/4 inches)
6.64.3
Practice Standards and Specifications
• Dewatering—Allow the maximum reasonable detention period before the
basin is completely dewatered (at least 48 hours).
• Inflow rate —Reduce the inflow velocity and divert all sediment -free
runoff.

root mat. Remove all surface soil containing high amounts of organic matter
and stockpile or dispose of it properly. Haul all objectionable material to the
designated disposal area. Place temporary sediment control measures below
basin as needed
2. Ensure that fill material for the embankment is free of roots, woody
vegetation, organic matter, and other objectionable material. Place the fill in
lifts not to exceed 9 inches, and machine compact it. Over fill the embankment
6 inches to allow for settlement.
3. Shape the basin to the specified dimensions. Prevent the skimming device
from settling into the mud by excavating a shallow pit under the skimmer or
providing a low support under the skimmer of stone or timber.
4. Place the barrel (typically 4-inch Schedule 40 PVC pipe) on a firm, smooth
foundation of impervious soil. Do not use pervious material such as sand,
gravel, or crushed stone as backfill around the pipe. Place the fill material
around the pipe spillway in 4-inch layers and compact it under and around
the pipe to at least the same density as the adjacent embankment. Care must
be taken not to raise the pipe from the firm contact with its foundation when
compacting under the pipe haunches.
Place a minimum depth of 2 feet of compacted backfill over the pipe spillway
before crossing it with construction equipment. In no case should the pipe
conduit be installed by cutting a trench through the dam after the embankment
is complete.
5. Assemble the skimmer following the manufacturers instructions, or as
designed.
6. Lay the assembled skimmer on the bottom of the basin with the flexible
joint at the inlet of the barrel pipe. Attach the flexible joint to the barrel pipe
and position the skimmer over the excavated pit or support. Be sure to attach
a rope to the skimmer and anchor it to the side of the basin. This will be used
to pull the skimmer to the side for maintenance.
7. Earthen spillwaysInstall the spillway in undisturbed soil to the greatest
extent possible. The achievement of planned elevations, grade, design width,
and entrance and exit channel slopes are critical to the successful operation
of the spillway. The spillway should be lined with laminated plastic or
impermeable geotextile fabric. The fabric must be wide and long enough to
cover the bottom and sides and extend onto the top of the dam for anchoring
in a trench. The edges may be secured with 8-inch staples or pins. The fabric
must be long enough to extend down the slope and exit onto stable ground.
The width of the fabric must be one piece, not joined or spliced; otherwise
water can get under the fabric. If the length of the fabric is insufficient for the
entire length of the spillway, multiple sections, spanning the complete width,
may be used. The upper section(s) should overlap the lower section(s) so
that water cannot flow under the fabric. Secure the upper edge and sides
of the fabric in a trench with staples or pins. (Adapted from "A Manual for
Designing, Installing and Maintaining Skimmer Sediment Basins." February,
1999. J. W. Faircloth & Son.).

9. Erosion control -Construct the structure so that the disturbed area is
minimized. Divert surface water away from bare areas. Complete the
embankment before the area is cleared. Stabilize the emergency spillway
embankment and all other disturbed areas above the crest of the principal
spillway immediately after construction (References: Surface Stabilization).
10. Install porous baffles as specified in Practice 6.65, Porous Baffles.
11. After all the sediment -producing areas have been permanently stabilized,
remove the structure and all the unstable sediment. Smooth the area to
blend with the adjoining areas and stabilize properly (References: Surface
Stabilization).
Maintenance Inspect skimmer sediment basins at least weekly and after each significant
(one-half inch or greater) rainfall event and repair immediately. Remove
sediment and restore the basin to its original dimensions when sediment
accumulates to one-half the height of the first baffle. Pull the skimmer to
one side so that the sediment underneath it can be excavated. Excavate the
sediment from the entire basin, not just around the skimmer or the first cell.
Make sure vegetation growing in the bottom of the basin does not hold down
the skimmer.
Repair the baffles if they are damaged. Re -anchor the baffles if water is
flowing underneath or around them.
If the skimmer is clogged with trash and there is water in the basin, usually
jerking on the rope will make the skimmer bob up and down and dislodge
the debris and restore flow. If this does not work, pull the skimmer over to
the side of the basin and remove the debris. Also check the orifice inside the
skimmer to see if it is clogged; if so remove the debris.
If the skimmer arm or barrel pipe is clogged, the orifice can be removed and
the obstruction cleared with a plumber's snake or by flushing with water. Be
sure and replace the orifice before repositioning the skimmer.
Check the fabric lined spillway for damage and make any required repairs
with fabric that spans the full width of the spillway. Check the embankment,
spillways, and outlet for erosion damage, and inspect the embankment for
piping and settlement. Make all necessary repairs immediately. Remove all
trash and other debris from the skimmer and pool areas.
Freezing weather can result in ice forming in the basin. Some special
precautions should be taken in the winter to prevent the skimmer from
plugging with ice.

Definition Porous barriers installed inside a temporary sediment trap, skimmer basin, or
sediment basin to reduce the velocity and turbulence of the water flowing
through the measure, and to facilitate the settling of sediment from the water
before discharge.
Purpose Sediment traps and basins are designed to temporarily pool runoff water to
allow sediment to settle before the water is discharged. Unfortunately, they
are usually not very efficient due to high turbulence and "short-circuiting"
flows which take runoff quickly to the outlet with little interaction with most
of the basin. Porous baffles improve the rate of sediment retention by distributing
the flow and reducing turbulence. This process can improve sediment retention.
Conditions Where This practice should be used in any temporary sediment trap, skimmer basin,
or temporary sediment basin.
Practice Applies
Planning Porous baffles effectively spread the flow across the entire width of a sediment
Considerations basin or trap. Water flows through the baffle material, but is slowed sufficiently
to back up the flow, causing it to spread across the entire width of the baffle
(Figure 6.65a).
Spreading the flow in this manner utilizes the full cross section of the basin,
which in turn reduces flow rates or velocity as much as possible. In addition,
the turbulence is also greatly reduced. This combination increases sediment
deposition and retention and also decreases the particle size of sediment captured.
The installation should be similar to a sediment fence (Figure 6.65b). The fabric
should be 700 g/m2 coir erosion blanket (Figure 6.65c) or equal. A support wire
across the top will help prevent excessive sagging if the material is attached to it
with appropriate ties.

Practice Standards and Specifications
Construction MATERIALS
Specifications 1. Use matting made of 100% coconut fiber (coir) twine woven into high
strength matrix with the properties shown in Table 6.65a.
2. Staples should be made of 0.125 inch diameter new steel wire formed into a
`U' shape not less than 12 inches in length with a throat of 1 inch in width. The
staples anchor the porous baffles into the sides and bottom of the basin.
3. Ensure that steel posts for porous baffles are of a sufficient height to support
baffles at desired height. Posts should be approximately 1-3/8" wide measured
parallel to the fence, and have a minimum weight of 1.25 lb/linear ft. The posts
must be equipped with an anchor plate having a minimum area of 14.0 square
inches and be of the self -fastener angle steel type to have a means of retaining
wire and coir fiber mat in the desired position without displacement.
4. Use 9-gauge high tension wire for support wire.

CONSTRUCTION
1. Grade the basin so that the bottom is level front to back and side to side.
2. Install the coir fiber baffles immediately upon excavation of the basins.
3. Install posts across the width of the sediment trap (Practice 6.62, Sediment
Fence).
4. Steel posts should be driven to a depth of 24 inches and spaced a maximum of
4 feet apart. The top of the fabric should be a minimum of 6 inches higher than
the invert of the spillway. Tops of baffles should be a minimum of 2 inches lower
than the top of the earthen embankment.
5. Install at least three rows of baffles between the inlet and outlet discharge
point. Basins less than 20 feet in length may use 2 baffles.
6. Attach a 9 gauge high tension wire strand to the steel posts at a height of 6
inches above the spillway elevation with plastic ties or wire fasteners to prevent
sagging. If the temporary sediment basin will be converted to a permanent
stormwater basin of a greater depth, the baffle height should be based on the pool
depth during use as a temporary sediment basin.

7. Extend 9 gauge minimum high tension wire strand to side of basin or install
steel T-posts to anchor baffle to side of basin and secure to vertical end posts as
shown in Figure 6.65b.
8. Drape the coir fiber mat over the wire strand mounted at a height of 6 inches
above the spillway elevation. Secure the coir fiber mat to the wire strand with
plastic ties or wire fasteners. Anchor the matting to the sides and floor of the
basin with 12 inch wire staples, approximately 1 ft apart, along the bottom and
side slopes of the basin.
9. Do not splice the fabric, but use a continuous piece across the basin
10. Adjustments may be required in the stapling requirements to fit individual
site conditions.
Maintenance Inspect baffles at least once a week and after each rainfall. Make any required
repairs immediately.
Be sure to maintain access to the baffles. Should the fabric of a baffle collapse,
tear, decompose, or become ineffective, replace it promptly.
Remove sediment deposits when it reaches half full, to provide adequate
storage volume for the next rain and to reduce pressure on the baffles.
Take care to avoid damaging the baffles during cleanout, and replace if damaged
during cleanout operations. Sediment depth should never exceed half the
designed storage depth.
After the contributing drainage area has been properly stabilized, remove all
baffle materials and unstable sediment deposits, bring the area to grade, and
stabilize it.

Baffles need to be installed correctly in order to fully provide their benefits.
Refer to Figure 6.65b and the following key points:
• The baffle material needs to be secured at the bottom and sides using
staples.
• Most of the sediment will accumulate in the first bay, so this should be
readily accessible for maintenance.

Design Criteria The temporary sediment trap or temporary sediment basin should be sized
using the appropriate design criteria.
The percent of surface area for each section of the baffle is as follows:
G
• inlet zone: 25%
• first cell: 25%
• second cell: 25%
• outlet zone: 25%
Baffle spacing in future permanent stormwater basins is beyond forebay.
Be sure to construct baffles up the sides of the trap or basin banks so water does
not flow around the structures. Most of the sediment will be captured in the inlet
zone. Smaller particle size sediments are captured in the latter cells. Be sure to
maintain access to the trap for maintenance and sediment removal. i Ill ill r o 1p,,"

wastewater being irrigated at this facility.
Response:
• WMSS has been assisting S&ME and Colonial Pipeline since October 2021 with
technical support associated with the wastewater irrigation system permit. During the
2022 calendar year WMSS obtained soil samples for annual permit compliance
associated with Condition IV.12. Additional soil samples beyond those required for

permit compliance were also obtained to further review the acreage associated with
the current irrigation system. WMSS will also assist with obtaining soil samples for
the 2023 calendar year for permit compliance.
The 2022 soil samples obtained had exchangeable sodium percentage (ESP) values
ranging from 1.8 to 15.7. Based upon these results, soil sodium values are borderline
high. At this time, the need for any remediation associated with the addition of soil
amendments is not necessary. After the 2023 soil samples are obtained, further
review of soil sample results will be performed.
Currently, the crop associated with the irrigation acreage is a mixture of fescue and
coastal bermuda. The coastal bermuda is extremely tolerant to higher sodium
concentrations within the soil profile. Past review of the irrigation acreage has not
indicated crop conditions that have evidenced signs of stress associated with current
soil conditions.
During future evaluations, if ESP values continue to rise, and if crop conditions
change, WMSS will assist Colonial Pipeline with any soil remediation
recommendations necessary.
WMSS appreciates the opportunity to assist in responding to the Additional Information
Request for the Colonial Pipeline — Greensboro Junction WWTF. If after reviewing the
enclosed information you have any questions or require any additional information,
please contact us at your convenience.
