Dear Mr. Matthews:
On behalf of our client, Colonial Pipeline Company, Wetland & Ecological Consultants
(WEC) respectfully requests authorization for the above referenced project pursuant to
Nationwide Permit (NWP) Nos. 3 and 18 for Maintenance and Minor Discharges,
respectively. The use of NWP 18 for this project requires the submittal of this
preconstruction notification (PCN). The proposed action consists of a maintenance
activity (NWP 3) required for an existing and serviceable petroleum pipeline located
within a maintained right-of-way (ROW), and subsequent streambed stabilization and
pipeline protection (NWP 18). The proposed activities will require disturbance to Guffy
Branch and an adjacent wetland area in Wake County, North Carolina, at 350 37'49"N
and 780 3725"W (Figure i).
Background
CPC's maintained ROW is approximately 8o feet in width at the location of the proposed
project, and contains three existing pipelines (Lines 22, 23, and 24). Line 22 is 16 inches
in diameter and transports refined petroleum products. Lines 23 and 24 are both eight
inches and diameter, and serve as reserve and contingency transport lines for shipping
refined petroleum products. Past high flow events have resulted in erosion within Guffy
Branch at CPC's ROW. These high flow events have resulted in the stream becoming
more incised causing Line 24 to be exposed within the creek channel (Photograph No. 1);
this exposure has significantly reduced the required protection level of this pipeline.

Proposed Activity in Waters of the U.S.
The maintenance activity will require temporary disturbance to approximately 30 linear
feet of Guffy Branch (Photograph No. 2) and to approximately o.o6 acre of an emergent
wetland that is adjacent to this creek (Photograph No. 3). After the maintenance all
three pipelines will be protected using pre-cast concrete revetment mats that will be
placed into approximately 6o linear feet of Guffy Branch and approximately o.oo6 acre
of the wetland (Figure 2). The quantity of fill "material" below the plane of the ordinary
high water mark will be less than 4.5 cubic yards, and the proposed activities will be
confined to CPC's existing ROW.
To ensure the integrity of the exposed pipeline (Line 24) at this location, CPC will
initially inspect the pipeline for any damages. This will require CPC to excavate a small
area (no larger than 30 feet by 6o feet) over pipeline location to be inspected. To
minimize sedimentation to the creek during the inspection and subsequent maintenance
activity, temporary dams will be constructed at each end of the maintenance area and the
stream flow will be pumped around the maintenance area. The dams will be constructed
of sandbags or other suitable material, and the pumps used will be able to sufficiently
accommodate the stream flow. The pumps will be installed above the upstream dam
with the discharge line routed through the maintenance area, discharging immediately
downstream of the downstream dam (Appendix A).
As an alternative method to using a pump, CPC may use a steel pipe flume to convey the
stream flow through the reach of stream to be disturbed. The flume will be used to
maintain flow to the downstream side of the maintenance area, and the excavation will
be carried out under the flume (Appendix B). Both techniques allow the maintenance to
take place without contact to flowing water, thus reducing downstream sedimentation.
Regardless of technique, upon completion of the maintenance activity, the stream
channel will be returned to its original contours (prior to the erosion) and the flow will
be restored.
With respect to the adjacent wetlands that will be disturbed during the maintenance
activities, equipment will be operated from mats, and stabilization will be conducted

immediately following completion of the maintenance activity. All excavated soils will be
temporarily stored on geotextile fabric or plastic sheeting until backfilling of the
excavation area. Measures will be taken to avoid any hydrology alteration (Appendix Q.
After the inspection, the pipeline will be recoated (if necessary), wrapped in a rock
shield, and buried beneath sandbags. To prevent future erosion of the streambed at this
location, and to protect the pipelines from damage, pre-cast concrete revetment mat will
be used to cover and protect all three pipelines while stabilizing the excavated portions of
the streambed as depicted in Appendix D. The revetment mat will extend approximately
6o linear feet within the stream and include approximately o.oo6 acre of the adjacent
wetlands. The stream banks will be stabilized with geotextile erosion control mats, and
CPC's Soil Erosion and Sedimentation Control Plan will be implemented to protect the
stream from sedimentation (Appendix E).

Conditions for NWP 18 (GS3362) MC No. 3402)
1. Enumerating and Reporting of Impacts:
a. Streams - Impacts to -streams shall be measured as length of the
centerline of the normal flow channel. Permanent and/or
temporary stream impacts shall be enumerated on the entire
project for all impacts regardless of which NWPs are used. Stream
relocations and stream bed and/or bank hardening are considered
to be permanent impacts.
This project will cause temporary disturbance to approximately 30
linear feet of Guffy Branch during the inspection and maintenance
activity (i.e., temporary disturbance authorized by NWP 3). After
any required maintenance, in a 6o-linear foot segment of the
stream, concrete revetment mats will be placed over the pipelines
as depicted in Appendix D, This approach will stabilize the
recently excavated stream bottom while protecting all three pipes
from future exposure (i.e., permanent impacts authorized by NWP
18)
b. Wetlands - Impacts to wetlands shall be measured as area.
Permanent and/or temporary wetland impacts shall be
enumerated on the entire project for all impacts regardless of
which NWPs are used.
This project will cause temporary disturbance to approximately
o.o6 acre of wetland during the excavation required to inspect the
pipelines. CPC proposes to place 8-foot wide revetment mats in
the stream channel to provide protection to the existing pipelines.
These mats will extend approximately two feet beyond the
ordinary high water mark on both stream banks and therefore into
the adjacent wetlands. This will result in approximately 24o
square feet (o.o06 acre) of fill in the wetland areas.
C. Lakes and Ponds - Impacts to waters other than streams and
wetlands shall be measured as area.

General Condition 19 - Mitigation
The proposed pipeline maintenance activities have been designed to avoid and
minimize impacts to jurisdictional waters to the maximum extent practicable. The
minimal amount of permanent impact associated with this project (i.e.,
approximately 60 linear feet of intermittent stream and o.006 acre of wetland) does
not emceed any of the regional conditions requiring mitigation (Refer to General
Condition 6 above). However, the proposed stream/bank stabilization completed to
maintain and protect the existing pipelines will result in improved water quality of
the stream by reducing soil/bank erosion, which offsets the temporary disturbance.

CPC'S SOIL EROSION AND SEDIMENTATION CONTROL PLAN
Colonial Pipeline Company
Soil Erosion and Sediment Control Plan
For
Pipeline Maintenance Activities
Objective
Disturbed areas are to be restored as close as practical to their original contours and
conditions so that once vegetation is reestablished, erosion will be reduced to the same
or lower level that existed prior to disturbance.
Description
This section defines the soil erosion and sediment control measures that Colonial
Pipeline Company will implement during and after inspection and repairs of the pipeline
are complete. The objectives of this plan are to establish general guidelines for
controlling erosion and sedimentation and to specify criteria for sensitive or particularly
susceptible soil areas. The plan incorporates measures to control erosion and
sedimentation, including minimizing cover removal, limiting the time of exposure,
limiting the flow of water onto the disturbed right-of-way, and filtering or settling out
sediment from water flowing from the right-of-way.
The primary objective of the soil erosion and sediment control plan is to reduce the area
and duration of soil disturbance and reestablish permanent vegetation as soon after
construction as possible, thereby minimizing long-term erosion and sedimentation.
Some erosion is inevitable during construction; however, the plan includes measures to
reduce erosion to the minimum practical.
Colonial Pipeline Company plans to reduce soil erosion and provide sediment control
during the repair of the pipeline at the project site by incorporating the following
measures:
• Water pumped from the construction area as part of the dewatering operation
from the excavation will be filtered through silt filtration bags and discharged to
a well-vegetated area.
• All work will be confined within the existing right-of-way. Staked hay bales and
silt fence will be installed around the worksite and maintained until vegetation is
established. Proper controls will be added if necessary during construction.
• All terms and conditions within Nationwide Permit 3 will be followed.
• Erosion control measures will be installed prior to conducting any soil disturbing
activities associated with the pipeline maintenance activity.
1 of 2
• Clearing of vegetation will be kept to an absolute minimum and confined to the
existing pipeline easement area. The easement area is 50 feet in width and devoid
of large trees. The right of way is vegetated with undergrowth grasses and other
short vegetation.
• Vegetation will be reestablished within disturbed areas and along stream banks
as soon as possible upon completion of work. Disturbed areas will be seeded
with a wetland seed mixture
• All erosion and sediment control measures will be inspected every two weeks at a
minimum and after every significant rainfall event of 0.5 inch or more until
disturbed areas have been stabilized. Identified damages to control measures
must be repaired immediately.
Refuse and Waste Disposal
Colonial's representative will not allow the Contractor to discard any litter, including
paper, bottles, cans, rags, sacks, welding rod stubs, fuel, crankcase draining, coating
materials, equipment, and junk pipe in the ditch or along the right-of-way. All refuse
must be collected and disposed in accordance with company specifications. Personnel
will be instructed regarding the correct procedure for waste disposal.
Maintenance/Inspection Procedures
The following inspection and maintenance practices will be implemented to maintain
erosion and sediment controls:
1. All control measures will be inspected every two weeks at a minimum and following
any storm event of 0.5 inch or greater.
2. All control measures will be maintained in good working order. If a repair is
necessary, it will be initiated within 24 hours of the report.
3. Built-up sediment will be removed from silt fences when it has reached one-third the
height of the fence.
4. Silt fences will be inspected for depth of sediment, tears, secure attachment of the
fabric to the fence posts, and firm placement of the fence posts in the ground.
5. Temporary and permanent seeding and planting will be inspected for bare spots,
washouts, and healthy growth.
6. Colonial Pipeline Company will select individuals to be responsible for inspections,
maintenance and repair activities, and completion of the inspection and
maintenance report. Personnel selected for inspection and maintenance
responsibilities will receive training from Colonial Pipeline Company or its
representative. Personnel must be trained in all practices necessary for maintaining
the erosion and sediment controls used on-site.

Colonial Pipeline Company Exposed Pipe Maintenance
Aqua Lane Site
Wake County, North Carolina
WEC Project No. 02-041901
Dear Mr. Matthews:
APR .1 7. 200
DiZNR - WAT9R QUALITY
On behalf of our client, Colonial Pipeline Company, Wetland & Ecological Consultants
(WEC) respectfully requests authorization for the above referenced project pursuant to
Nationwide Permit (NWP) Nos. 3 and 18 for Maintenance and Minor Discharges,
respectively. The use of NWP 18 for this project requires the submittal of this
preconstruction notification (PCN). The proposed action consists of a maintenance
activity (NWP 3) required for an existing and serviceable petroleum pipeline located
within a maintained right-of-way (ROW), and subsequent streambed stabilization and
pipeline protection (NWP 18). The proposed activities will require disturbance to Guffy
Branch and an adjacent wetland area in Wake County, North Carolina, at 35° 37' 49"N
and 780 3725"W (Figure 1).
Background
CPC's maintained ROW is approximately 8o feet in width at the location of the proposed
project, and contains three existing pipelines (Lines 22, 23, and 24). Line 22 is 16 inches
in diameter and transports refined petroleum products. Lines 23 and 24 are both eight
inches and diameter, and serve as reserve and contingency transport lines for shipping
refined petroleum products. Past high flow events have resulted in erosion within Guffy
Branch at CPC's ROW. These high flow events have resulted in the stream becoming
more incised causing Line 24 to be exposed within the creek channel (Photograph No. 1);
this exposure has significantly reduced the required protection level of this pipeline.

Proposed Activity in Waters of the U.S.
The maintenance activity will require temporary disturbance to approximately 3o linear
feet of Guffy Branch (Photograph No. 2) and to approximately o.o6 acre of an emergent
wetland that is adjacent to this creek (Photograph No. 3). After the maintenance all
three pipelines will be protected using pre-cast concrete revetment mats that will be
placed into approximately 6o linear feet of Guffy Branch and approximately o.oo6 acre
of the wetland (Figure 2). The quantity of fill "material" below the plane of the ordinary
high water mark will be less than 4.5 cubic yards, and the proposed activities will be
confined to CPC's existing ROW.
To ensure the integrity of the exposed pipeline (Line 24) at this location, CPC will
initially inspect the pipeline for any damages. This will require CPC to excavate a small
area (no larger than 30 feet by 6o feet) over pipeline location to be inspected. To
minimize sedimentation to the creek during the inspection and subsequent maintenance
activity, temporary dams will be constructed at each end of the maintenance area and the
stream flow will be pumped around the maintenance area. The dams will be constructed
of sandbags or other suitable material, and the pumps used will be able to sufficiently
accommodate the stream flow. The pumps will be installed above the upstream dam
with the discharge line routed through the maintenance area, discharging immediately
downstream of the downstream dam (Appendix A).
As an alternative method to using a pump, CPC may use a steel pipe flume to convey the
stream flow through the reach of stream to be disturbed. The flume will be used to
maintain flow to the downstream side of the maintenance area, and the excavation will
be carried out under the flume (Appendix B). Both techniques allow the maintenance to
take place without contact to flowing water, thus reducing downstream sedimentation.
Regardless of technique, upon completion of the maintenance activity, the stream
channel will be returned to its original contours (prior to the erosion) and the flow will
be restored.
With respect to the adjacent wetlands that will be disturbed during the maintenance
activities, equipment will be operated from mats, and stabilization will be conducted
2

Aqua Lane WECProjectNo. o2-o4igol
immediately following completion of the maintenance activity. All excavated soils will be
temporarily stored on geotextile fabric or plastic sheeting until backfilling of the
excavation area. Measures will be taken to avoid any hydrology alteration (Appendix Q.
After the inspection, the pipeline will be recoated (if necessary), wrapped in a rock
shield, and buried beneath sandbags. To prevent future erosion of the streambed at this
location, and to protect the pipelines from damage, pre-cast concrete revetment mat will
be used to cover and protect all three pipelines while stabilizing the excavated portions of
the streambed as depicted in Appendix D. The revetment mat will extend approximately
6o linear feet within the stream and include approximately o.oo6 acre of the adjacent
wetlands. The stream banks will be stabilized with geotextile erosion control mats, and
CPC's Soil Erosion and Sedimentation Control Plan will be implemented to protect the
stream from sedimentation (Appendix E).

Conditions for NWP 18 (GS3362) MC No. 3402)
1. Enumerating and Reporting of Impacts:
a. Streams - Impacts to streams shall be measured as length of the
centerline of the normal flow channel. Permanent and/or
temporary stream impacts shall be enumerated on the entire
project for all impacts regardless of which NWPs are used. Stream
relocations and stream bed and/or bank hardening are considered
to be permanent impacts.
This project will cause temporary disturbance to approximately 30
linear feet of Guffy Branch during the inspection and maintenance
activity (i.e., temporary disturbance authorized by NWP 3). After
any required maintenance, in a 6o-linear foot segment of the
stream, concrete revetment mats will be placed over the pipelines
as depicted in Appendix D, This approach will stabilize the
recently excavated stream bottom while protecting all three pipes
from future exposure (i.e., permanent impacts authorized by NWP
18)
b. Wetlands - Impacts to wetlands shall be measured as area.
Permanent and/or temporary wetland impacts shall be
enumerated on the entire project for all impacts regardless of
which NWPs are used.
This project will cause temporary disturbance to approximately
o.06 acre of wetland during the excavation required to inspect the
pipelines. CPC proposes to place 8-foot wide revetment mats in
the stream channel to provide protection to the existing pipelines.
These mats will extend approximately two feet beyond the
ordinary high water mark on both stream banks and therefore into
the adjacent wetlands. This will result in approximately 240
square feet (o.oo6 acre) of fill in the wetland areas.
C. Lakes and Ponds - Impacts to waters other than streams and
wetlands shall be measured as area.

(c) Form of Notification:
The Wilmington District's PCN form is attached as Appendix F.
General Condition 14 - Compliance Certification
Upon completion of the required maintenance, WEC (as CPC's authorized agent)
will sign and submit the USACE certification letter documenting compliance with
maintenance activities as they are described in this PCN submittal.
General Condition Ls - Use of Multiple Nationwide Permits
This project will use both NWP 3 and NWP 18. The cumulative impacts of both
parts of this project will not exceed the highest specified acreages or linear feet of
either NWP.
General Condition 16 - Water Supply Intakes
The proposed construction does not include a water supply intake.
General Condition 12 - Shellfish Beds
The proposed project is not located within or adjacent to a shellfish bed.
General Condition 18 - Suitable Material
Only material excavated from the maintenance area will be replaced within the
trench following maintenance completion. As described above the concrete
revetment mats are pre-cast and hardened before they are placed in the stream.
General Condition 19 - Mitigation
The proposed pipeline maintenance activities have been designed to avoid and
minimize impacts to jurisdictional waters to the maximum extent practicable. The
minimal amount of permanent impact associated with this project (i.e.,
approximately 6o linear feet of intermittent stream and mo6 acre of wetland) does
not exceed any of the regional conditions requiring mitigation (Refer to General
Condition 6 above). However, the proposed stream/bank stabilization completed to
maintain and protect the existing pipelines will result in improved water quality of
the stream by reducing soil/bank erosion, which offsets the temporary disturbance.
General Condition 20 - Spawning Areas
Not applicable

POVNWPNos. 3 and 18 April io, 2oo6
Aqua Lane WECProjectNo. o2-o419o1
General Condition 21- Management of Water Flows
During the maintenance activity, water flows will be maintained by the use of either
a dam and pump system (Appendix A) or a flume used to convey the flow of the
stream (Appendix B). The concrete revetment mats will be "keyed" in to the
upstream end of the maintenance area to ensure that flow of the stream is not
impeded (Appendix D).
General Condition 22 - Adverse Effects from Impoundments
Not applicable
General Condition 23 - Waterfowl Breeding Areas
Waterfowl breeding areas do not occur on the subject site.
General Condition 24 - Removal of Temporary Fills
All temporary soil piles will be removed immediately following the maintenance
activity.
General Condition 26 - Designated Critical Resource Waters
Not applicable
General Condition 26 - Fills within loo-year Floodplains
The project will not result in above grade fill placed within the :Loo-year floodplain.
General Condition 2Z - Construction Period
Not applicable
Conclusion
The pipeline maintenance activity proposed in jurisdictional waters of the U.S. and the
State of North Carolina will result in disturbance to approximately 6o linear feet of Guffy
Branch and o.o6 acre of an adjacent wetland. There will be no disturbance to
jurisdictional waters located outside of CPC's existing ROW. During the maintenance
activity, appropriate erosion and sedimentation control devices will be used on the entire
project site and the proposed activity is in compliance with Nationwide Permit General
Conditions and NCDWQ conditions for Section 401 water quality certification and
riparian buffer protection.

CPC'S SOIL EROSION AND SEDIMENTATION CONTROL PLAN
Colonial Pipeline Company
Soil Erosion and Sediment Control Plan
For
Pipeline Maintenance Activities
Objective
Disturbed areas are to be restored as close as practical to their original contours and
conditions so that once vegetation is reestablished, erosion will be reduced to the same
or lower level that existed prior to disturbance.
Description
This section defines the soil erosion and sediment control measures that Colonial
Pipeline Company will implement during and after inspection and repairs of the pipeline
are complete. The objectives of this plan are to establish general guidelines for
controlling erosion and sedimentation and to specify criteria for sensitive or particularly
susceptible soil areas. The plan incorporates measures to control erosion and
sedimentation, including minimizing cover removal, limiting the time of exposure,
limiting the flow of water onto the disturbed right-of-way, and filtering or settling out
sediment from water flowing from the right-of-way.
The primary objective of the soil erosion and sediment control plan is to reduce the area
and duration of soil disturbance and reestablish permanent vegetation as soon after
construction as possible, thereby minimizing long-term erosion and sedimentation.
Some erosion is inevitable during construction; however, the plan includes measures to
reduce erosion to the minimum practical.
Colonial Pipeline Company plans to reduce soil erosion and provide sediment control
during the repair of the pipeline at the project site by incorporating the following
measures:
• Water pumped from the construction area as part of the dewatering operation
from the excavation will be filtered through silt filtration bags and discharged to
a well-vegetated area.
• All work will be confined within the existing right-of-way. Staked hay bales and
silt fence will be installed around the worksite and maintained until vegetation is
established. Proper controls will be added if necessary during construction.
• All terms and conditions within Nationwide Permit 3 will be followed.
• Erosion control measures will be installed prior to conducting any soil disturbing
activities associated with the pipeline maintenance activity.
1 of 2
• Clearing of vegetation will be kept to an absolute minimum and confined to the
existing pipeline easement area. The easement area is 50 feet in width and devoid
of large trees. The right of way is vegetated with undergrowth grasses and other
short vegetation.
• Vegetation will be reestablished within disturbed areas and along stream banks
as soon as possible upon completion of work. Disturbed areas will be seeded
with a wetland seed mixture
• All erosion and sediment control measures will be inspected every two weeks at a
minimum and after every significant rainfall event of 0.5 inch or more until
disturbed areas have been stabilized. Identified damages to control measures
must be repaired immediately.
Refuse and Waste Disposal
Colonial's representative will not allow the Contractor to discard any litter, including
paper, bottles, cans, rags, sacks, welding rod stubs, fuel, crankcase draining, coating
materials, equipment, and junk pipe in the ditch or along the right-of-way. All refuse
must be collected and disposed in accordance with company specifications. Personnel
will be instructed regarding the correct procedure for waste disposal.
Maintenance/Inspection Procedures
The following inspection and maintenance practices will be implemented to maintain
erosion and sediment controls:
i. All control measures will be inspected every two weeks at a minimum and following
any storm event of 0.5 inch or greater.
2. All control measures will be maintained in good working order. If a repair is
necessary, it will be initiated within 24 hours of the report.
3. Built-up sediment will be removed from silt fences when it has reached one-third the
height of the fence.
4. Silt fences will be inspected for depth of sediment, tears, secure attachment of the
fabric to the fence posts, and firm placement of the fence posts in the ground.
5. Temporary and permanent seeding and planting will be inspected for bare spots,
washouts, and healthy growth.
6. Colonial Pipeline Company will select individuals to be responsible for inspections,
maintenance and repair activities, and completion of the inspection and
maintenance report. Personnel selected for inspection and maintenance
responsibilities will receive training from Colonial Pipeline Company or its
representative. Personnel must be trained in all practices necessary for maintaining
the erosion and sediment controls used on-site.

Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The proposed proiect is designed to minimize impacts to iurisdictional waters as much as
practicable. The revetment mats will only be used to protect CPC's pipelines and to stabilize the
area that had been excavated.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Updated 11/1/2005
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
llqp://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
