Dear Mr. Shern:
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
respectively, for the required maintenance of three existing and serviceable pipelines known
as Lines 22, 23 and 24. 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
Beaver Creek at 35° 44' 9.8988"N, 78° 52' 53.5074"W located in Wake 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, the 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, bank erosion and streambed
degradation has exposed Line 22 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.
The proposed pipeline maintenance is part of CPC's Integrity Management Program (IMP).
The IMP provides an important means of achieving spill-free, error-free operations. The
purpose of the IMP is to improve the integrity of CPC's system - including pipelines,
facilities, equipment, tanks and delivery lines.
CPC's IMP also meets the requirements of 49 CFR Part 195 - "Pipeline Safety: Pipeline
Integrity in High Consequence Areas (Hazardous Liquid Operators with 500 or More Miles
of Pipeline); Final Rule." § § 195.45o and 195.452 as administered by the U.S. Department of
Transportation (USDOT). Federal Code requires an IMP, which includes prescriptive
requirements for inspection of pipeline systems, and requires excavation of certain defects
according to specific schedules. It should be noted that USDOT has completed an
Environmental Assessment (EA) under the National Environmental Policy Act (NEPA)
concerning repairs an operator would have to make to its pipeline following an integrity
assessment. The EA and corresponding Finding of No Significant Impact concluded that
these actions would not significantly affect the quality of the human environment (Docket
No. RSPA-oo-6355)• WEC conducted a field delineation to locate jurisdictional waters at the
maintenance location on January 4, 2011 (Appendix A).

Proposed Activity in Waters of the U.S.
The maintenance activity will require temporary disturbance to approximately 70 linear feet
of an unnamed intermittent stream to maintain and protect the existing pipeline at this
location. In December 2010, sandbags were temporarily hand placed over exposed Line 22
for temporary protective cover and will be removed before the maintenance work begins.
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 exposure 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 B).
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 Q. Both techniques allow the maintenance to take place without
contact to flowing water (i.e., "in the dry"), thus reducing downstream sedimentation.
Following the pipeline inspection, articulated grout revetment mats will be used to cover the
pipelines within the streambed (Appendix D). The mats will provide adequate cover to
protect the exposed pipeline from damages, including high-flow events. The mats will be
"keyed" into both the stream bed and the stream banks. Prior to mat placement, the
streambanks will be "laid back" to increase stability of the mat system. Following placement
of the mats, they will be allowed to harden (two to three hours), before restoring stream flow.
The articulated revetment mats will be placed within a 70-linear foot segment of the stream
channel, and underlaid with geotextile fabric. The quantity of this "fill material" below the
plane of the ordinary high water mark will not exceed 12 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 E).
Nationwide Permit General Conditions Summary
We have provided the following information to document compliance with the USACE NWP
general conditions. Each condition and subcategory is itemized below.

be allowed to harden (approximately two to three hours) before restoring stream flow.
General Condition 7 - Water Supply Intakes
The proposed construction does not include a water supply intake.
General Condition 8 - Adverse Effects from Impoundments
Not applicable.
General Condition g - Management of Water Flows
During the proposed activity, water flows will be maintained by the use of either a dam
and pump system (Appendix B) or a flume used to convey the flow of the stream
(Appendix Q. The grout revetment mats will be "keyed" in to both the stream bed and
the stream banks to prevent impediment of streamflow (Appendix D).
General Condition lo - Fills Within loo-Year Floodplains
The project will not result in above grade fill placed within the loo-year floodplain
(Appendix F).
General Condition ii - 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 E).

Colonial Pipeline Company - Pipeline Maintenance WEC Project No. 02-041901
Lines 22-24 - Tributary to Beaver Creek
General Condition 13 - Removal of Temporary Fills
All temporary water flow diversion devices will be removed immediately following the
maintenance activity.
General Condition 14 - Proper Maintenance
The existing pipelines and ROW will continue to be maintained and inspected on a
regular basis to ensure public safety.
General Condition in - 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 Service (USFWS) data, the federally protected species
listed as potentially occurring in Wake County include: the red-cockaded woodpecker
(Picoides borealis); dwarf wedgemussel (Alasmidonta heterodon); and Michaux's
sumac (Rhus michauxii). The bald eagle (Haliaeetus leucocephalus), which is protected
under the Bald and Golden Eagle Protection Act is also listed potentially occurring in
Wake County. Neither the small, unnamed intermittent stream nor the regularly-
mowed existing pipeline ROW provide suitable habitat for any of these species.
Additionally these species were not observed at the project site during our field
investigation on January 4, 2011. In summary this project is not anticipated to
adversely affect federally protected 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 19 - 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 stabilization
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.

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 150 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

stream above and below a pipe or culvert should not be modified by
widening the stream channel or by reducing the depth of the stream
in connection with the construction activity. The width, height, and
gradient of a proposed opening should be such as to pass the average
historical low flow and spring flow without adversely altering flow
velocity. Spring flow should be determined from gage data, if
available. In absence of such data, bankfull flow can be used as a
comparable level.
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

Explain:
1 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 III: 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 III.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 III.B 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 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.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.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 2610acres
Drainage area: 34 `acres
Average annual rainfall: inches

Tributary stream order, if known: first.
a Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.
(b) General Tributary Characteristics (check all that apply):

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:

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.
0 All terms and conditions within Nationwide Permit 3 will be followed.
t 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 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
Coloniars 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.

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:
70 linear feet of an intermittent 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 Transportation (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 70 linear feet of an unnamed intermittent 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 B 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 Cin 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 70-linear foot segment of the stream channel, underlaid with and geotextile filter
fabric (see Appendix D 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 12 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 E 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.
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.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for ? Yes ® No

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or ? Yes ® No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act ? Yes ® No
impacts?

5c. If yes, indicate the USFWS Field Office you have contacted. ?
Raleigh
? Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
Reviewed existing USFWS recoreds for the area and conducted filed survey for species known to occur in the area.
According to current U.S. Fish and Wildlife Service (USFWS) data, the federally protected species listed as potentially
occurring in Wake County include: the red-cockaded woodpecker (Picoides borealis); dwarf wedgemussel (Alasmidonta
heterodon); and Michaux's sumac (Rhus michauxii). The bald eagle (Haliaeetus leucocephalus), which is protected
under the Bald and Golden Eagle Protection Act is also listed potentially occurring in Wake County. Neither the small,
unnamed stream nor the regularly-mowed existing pipeline right-of-way provide suitable habitat for these species.
Additionally these species were not observed at the project site during our field investigation on December 17, 2010.
6. Essential Fish Habitat (Corps Requirement)
