3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
A cleared maintained and mowed ROW along CPC's pipeline corridor.
3b. List the total estimated acreage of all existing wetlands on the property:
None
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
87 linear feet of perennial stream within the existing ROW.
3d. Explain the purpose of the proposed project:
Pipeline maintenance, lack of pipeline protective cover, as required by the U.S. Department of Trasportation (USDOT).
3e. Describe the overall project in detail, including the type of equipment to be used:
The maintenance activity will require temporary disturbance to approximately 87 linear feet of an unnamed perennial stream
to stabilize the stream banks and protect an existing petroleum pipeline at this location. All pipeline maintenance
activities will occur within the existing and maintained ROW.
To ensure the integrity of the Line 1 at this location, CPC will initially inspect the pipeline for any damages. This will require
CPC to excavate a small area over the pipeline to inspect the pipeline for damage. 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 at each site. The dams will be
constructed of sandbags or other suitable material, and the pump capacity 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 (see Appendix A in the attached
document).
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 disturbed area, and the
excavation will be carried out under the flume (see Appendix B in the attached document). Both techniques allow the
maintenance to take place without contact to flowing water (i.e., "in the dry"), thus reducing downstream sedimentation.
Following the inspection of the pipeline and the completion of the pipeline maintenance activities, the pipeline will be protected
using pre-cast concrete revetment mats placed within the existing CPC ROW, over the existing pipelines. Specifically,
the pre-cast revetment mats will be placed within an 87-linear foot segment of the stream channel, underlaid with and
geotextile fabric (see Appendix C in the attached document). The quantity of this "fill material" (i.e., revetment mat) below
the plane of the ordinary high water mark will be approximately 3.5 cubic yards.
During the maintenance and subsequent stabilization CPC's Soil Erosion and Sedimentation Control Plan will be
implemented to protect the streams from sedimentation (see Appendix D in the attached document). There will be no
disturbance to jurisdictional waters located outside of CPC's ROW.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed pipeline maintenance activities have been designed to avoid and minimize impacts to jurisdictional waters to the
maximum extent practicable. The temporary stream disturbances do not exceed any of the USACE, Wilmington District,
Nationwide Permit Regional Conditions requiring mitigation [Refer to USACE, Wilmington District Regional Condition 3 (2)
below]. Nevertheless, the proposed stream/bank stabilizations completed to maintain and protect the existing pipelines will
result in improved water quality of the stream by reducing soil/bank erosion, which will offset the minor/temporary disturbances
associated with the required pipeline maintenance. To ensure that the existing plant community is reestablished following the
proposed activity, CPC will segregate the topsoil containing seeds and rhizomes from the rest of the excavated soil. Upon
completion of the maintenance activity, the excavated area will be backfilled, and the topsoil will be returned to the top of the
excavated area.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Equipment will be operated from the stream banks to avoid any impacts to the stream from the machinery.

Pipeline Maintenance
Davidson County, North Carolina
WEC Project No. 02-041901
Dear Mr. Thomas:
On behalf of our client, Colonial Pipeline Company (CPC), 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, for the
required maintenance of CPC's existing Line 1 and Line 2 pipelines. The use of NWP 18 for
these projects requires the submittal of this preconstruction notification (PCN). The
proposed actions consist of maintenance activities (NWP 3) required for an existing and
serviceable petroleum pipeline (Line 1) located within a maintained right-of-way (ROW), and
subsequent streambed stabilization and pipeline protection (NWP 18) for Lines 1 and 2. The
proposed activities will require temporary disturbance to an unnamed tributary to South
Potts Creek at 350 47' 16.44"N 8o- 21' 56.52"W located in Davidson County, North Carolina
(Figurer).
Background
CPC is committed to operating their pipelines and support facilities in a manner that protects
the safety of the public, environment, and its workforce. The proposed pipeline maintenance
will be performed to prevent potential damage to the pipeline and ensure pipeline integrity.
CPC's above referenced maintained ROW, contains two pipelines that transport refined
petroleum: Line 1, 4o-inch diameter; Line 2, 36-inch diameter. At the above referenced site,
due to bank erosion and streambed degradation Line 1 has only eight inches of cover within
the stream channel, which is significantly less than the required cover protection level of the

pipeline. As required by the U.S. Department of Transportation (USDOT), CPC must inspect
and repair the pipeline area with the reduced cover at this location.
Proposed Activity in Waters of the U.S.
The maintenance activity will require temporary disturbance to approximately 87 linear feet
of an unnamed perennial stream to stabilize the stream banks and protect the existing
pipeline at this location.
To ensure the integrity of the Line i at this location, CPC will initially inspect the pipeline for
any damages. This will require CPC to excavate a small area over the pipeline to inspect the
pipeline for damage. 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 at each
site. The dams will be constructed of sandbags or other suitable material, and the pump
capacity 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 disturbed 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 (i.e., "in the dry"), thus reducing downstream sedimentation.
Following the inspection of the pipeline and the completion of the pipeline maintenance
activities, the pipeline will be protected using pre-cast concrete revetment mats placed within
the existing CPC ROW, over the existing pipelines. Specifically, the pre-cast revetment mats
will be placed within an 87-linear foot segment of the stream channel, underlaid with and
geotextile fabric (Appendix Q. The quantity of this "fill material" (i.e., revetment mat) below
the plane of the ordinary high water mark will be approximately 3.5 cubic yards.
During the maintenance and subsequent stabilization CPC's Soil Erosion and Sedimentation
Control Plan will be implemented to protect the streams from sedimentation (Appendix D).
There will be no disturbance to jurisdictional waters located outside of CPC's ROW.

general conditions. Each condition and subcategory is itemized below.
General Condition i - Navigation
The project site does not occur within navigable waters.
General Condition 2 - Aquatic Life Movements
The discharge of fill activity within the stream will be minimal. The revetment mats will
be "keyed" into the streambeds, and will not impede the passage of normal stream flow
or aquatic life.
General Condition 3 - Spawning Areas
Not applicable.
General Condition 4 - Migratory Bird Breeding Areas
Not applicable
General Condition , - Shellfish Beds
Not applicable
General Condition 6 - Suitable Material

General Condition 16 - Tribal Rights
The project sites are not located within or adjacent to an Indian reservation or nation.
General Condition 17 - Endangered Species
No impacts to federally protected species are expected from this project. According to
current U.S. Fish and Wildlife Service (USFWS) data, the federally protected species
listed as potentially occurring in Davidson County is the Schweinitz's sunflower
(Helianthus schweinitzii). This species was not observed at the maintenance location
(i.e., on the existing and maintained pipeline ROW) during a field inspection of the site
conducted by WEC on July 13, 2009, which is within the flowering period for this
species.
General Condition 18 - Historic Properties
The proposed activities will be conducted within the existing pipeline ROW, which has
been previously disturbed; thus no archeological resource impacts are probable. No
historic structures were noted within the project areas, and no aboveground structures
are proposed for construction. Therefore, the proposed pipeline protection activities
will have no adverse affects to cultural resources in the project vicinity.
General Condition 1g - Designated Critical Resources Waters
Not applicable.
General Condition 20 - Mitigation

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 At filtration bags and discharged to
a well-vegetated area.
• All work will be confined within the existing right-of-way. Staked bay bales and silt
fence will be instped around the worksite'and maintained until vegetation is established.
Proper controb 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.
• Clearing of vegetation will be kept to an absolute minimum and confined to the
existing pipeline easement area. The easement area is 5o 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 o.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.

Explain:
1 Boxes checked below shall be supported by completing the appropriate sections in Section Ill below.
z For purposes of this form, an RPW is defined as a tributary that is not a TN W and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
' Supporting documentation is presented in Section III.F.
SECTION Ill: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section 111.A.1 and Section III.D.I. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section III.D.1.; otherwise, see Section II1.13 below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanoshave been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.BA for
the tributary, Section 1H.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section HLC below.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section 111.13:
2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into

adjacent wetlands, then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of
presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to

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 project is designed to minimize impacts to jurisdictional waters as much as
practicable. The revetment mat will only be used to protect CPC's existing pipeline and to
stabilize the stream bank.
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
Updated 11/1/2005
Page 9 of 12
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
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
htlp://h2o.enr.state.nc.us/ncwetlands/strmgide.html.

construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
