Dear Mr. Williams:
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 three existing and serviceable pipelines
known as Lines 22, 23 and 24. The use of NWP 18 for this project requires the submittal
of this preconstruction notification (PCN). The proposed actions consist of maintenance
activities (NWP 3) required for these existing and serviceable petroleum pipelines within
CPC's maintained right-of-way (ROW), and subsequent streambed stabilization and
pipeline protection (NWP 18). The proposed activities will require temporary
disturbance to an unnamed tributary to Big Alamance Creek at 35° 57'39-312"N 79° 41'
37.2114"W located in Guilford 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 pipelines and ensure
pipeline integrity. CPC's above referenced maintained ROW, contains three pipelines
that transport refined petroleum: Line 22, 16-inch diameter; Line 23, eight-inch

diameter; and Line 24, eight-inch diameter. At the above referenced site, due to bank
erosion and streambed degradation Line 22 has been exposed within the stream channel,
thus the required protection level of the pipeline has been lost. As required by the U.S.
Department of Transportation (USDOT) the pipeline regulatory authority, CPC must
inspect and repair the exposed pipeline at this location.
Proposed Activity in Waters of the U.S.
The maintenance activity.will require temporary disturbance to approximately 55 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 22 at this location, CPC will initially inspect the line
for any damages. This will require CPC to excavate a small pit at the location which will
allow CPC personnel to inspect the integrity of the subject pipeline segment. 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-formed articulated grout revetment
mats placed within the existing CPC ROW, over the existing pipelines. Specifically, the
articulated grout mats will be placed within a 55-linear foot segment of the stream
channel, underlaid with and geotextile fabric (Appendix Q. The quantity of this "fill

material" below the plane of the ordinary high water mark will not exceed 8.15 cubic
yards. The grout revetment mats will be allowed to completely harden (in the dry) before
the stream flow is restored.
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.
Nationwide Permit General Conditions Summary

General Condition I - Water Supply Intakes
The proposed construction does not include a water supply intake.
General Condition 8 - Adverse Effects from Impoundments
Not applicable.
General Condition q - Management of Water Flows
During the proposed 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 revetment mats will be "keyed" in to the upstream end of
the disturbed areas to prevent impediment of streamflow (Appendix Q.
General Condition lo - Fills Within ioo-Year Floodplains
The project will not result in above grade fill placed within the ioo-year floodplain.
General Condition n - Equipment
Equipment will be operated from the stream banks.
General Condition 12 - Soil Erosion and Sediment Controls
Best Management Practices and proper erosion and sedimentation controls will be
followed during the maintenance activities (Appendix D).
General Condition ij - Removal of Temporary Fills
All temporary water flow diversion devices will be removed immediately following
the maintenance activity.
General Condition la - Proper Maintenance
The existing pipelines and ROW will continue to be maintained and inspected on a
regular basis to ensure public safety.
General Condition it; - Wild and Scenic Rivers
The project site is not located in or adjacent to a Wild and Scenic River.
General Condition 16 - Tribal Rights
The project site is 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 data, the only federally protected species listed to
occur in Guilford County is the small whorled pogonia (Isotria medeoloides). At the

March 24, 2010
WEC Project No. 02-041901
maintenance location, the pipeline ROW is regularly mowed, and does not provide
suitable habitat for the small whorled pogonia.
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 i9 - Designated Critical Resources Waters
Not applicable.
General Condition 20 - Mitigation
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.
General Condition 21 - Water Quality
The activity will be in accordance with the conditions of the DWQ General
Certifications for NWP 3 (WQC NO. 3687) and NWP 18 (WQC No. 3705).

3.0 List of Final Wilmington District Regional Modifications and Conditions
for All Nationwide Permits:
3.1 NWPs may not be used for activities that may result in the loss or
degradation of greater than 300 total linear feet of perennial,
intermittent, or ephemeral streams that exhibits important
aquatic function(s). Loss of stream includes the linear feet of
stream bed that is filled, excavated, or flooded by the proposed
activity.
The proposed activities will disturb less than 300 linear feet of
stream.
3.2 For any NWP that results in impacts more than 150 total linear
feet of perennial and/or ephemeral/intermittent stream, the
applicant shall provide a mitigation plan to compensate for the
loss of aquatic function, associated with the proposed activity. For
stream impacts of less than i5o linear feet compensatory
mitigation is determined on a case by case basis.
Stream impact is less than 150 linear feet, and the proposed
pipeline protection activity will improve water quality and the
aquatic environment by reducing bank erosion and stream
turbidity.
3.3 For any NWP that results in a loss of more than 150 linear feet of
perennial and/or intermittent/ephemeral stream, the applicant
must comply with NWP General Condition 27 (PCN).
Not applicable (i.e., less than 150 linear feet of stream); however, a
PCN is required for NWP 18 and compliance with NWP General
Condition No. 27 has been provided by the submission of this
PCN.
3.4 For all NWPs which allow the use of concrete as a building
material, measures will be taken to prevent live or fresh concrete,
including bags of uncured concrete from coming into contact with
waters of the state until the concrete has hardened.
During the maintenance activities streamflow will be isolated
through either a dam and pump (Appendix A) or a flume pipe
technique (Appendix B). Streamflow will not be returned to the
maintenance area until the grout revetment mats have fully
hardened.

Not applicable.
3.7 Applicants shall notify the NCDENR Shellfish Sanitation Section
prior to dredging in or removing sediment from an area closed to
shell fishing where the effluent may be released to an area open for
shell fishing or swimming in order to avoid contamination of the
disposal area and allow a temporary shellfish closure to be made.
Any disposal of sand to the beach should occur between November
i and April 30 when recreational usage is low. Only clean sand
should be used and no dredged sand from closed shell fishing
areas. If beach disposal was to occur at times other than stated
above or if sand from a closed shell fishing area is to be used, a
swim advisory shall be posted, and a press release shall be made.
Not applicable.
3.8 Adverse impacts to Submerged Aquatic Vegetation are not
authorized by any NWP within any of the 20 costal counties.

sedimentation (Appendices A and B).
7. Riparian Area Protection (Buffer) Rules
Not applicable; the site is not located within the Catawba, Neuse, Tar-
Pamlico, or Randleman river basins.
8. Water Supply Watershed Buffers
The stream is located within a WS-IV, NSW designated watershed (Big
Alamance Creek). However, it is our opinion that project is allowable per
the DWG "Redbook" [15NCAC 02B .0216(3)(b)(i)(G)] as it will not result
in increased impervious areas and there is no practical alternative.
Further, the proposed action will result in reduced stream sedimentation
(i.e., maintain/improve water quality) and protect the pipelines from
damage that may result in a release of petroleum into a stream within the
protected watershed.
9. If concrete is used during the construction, then a dry work area should be
maintained to prevent direct contact between curing concrete and stream water.

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 G reduce sail 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 Oration bap 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 instilled around the worlashe'and maintained until vegetation is established.
Proper controb w11 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 wM 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 o.s 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 wM be inspected every two weeks at a minimum and foilowmg
any storm event of o.s 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.
s. 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:
Boxes checked below shall be supported by completing the appropriate sections in Section III below.
z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
3 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 11I.A.1 and Section III.D.1. 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 HIM 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 Rapanos have 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 waterbody4 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.B.1 for
the tributary, Section III.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 III.C below.

the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

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:

findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:

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:
55 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 55 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 Lines 22-24 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 grout mats will be placed within an 55-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 8.15 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
1 a. 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.
1 b. 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.
