Colonial Pipeline Company Exposed Pipe Maintenance DENR - WATER QUALITY
Cane Creek Tributary Station No. 1998+54 WETLANDS AND STORMWATER BRANCH
Mecklenburg 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, respectively, for the required maintenance of CPC's existing Line 2 pipeline.
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 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 temporary disturbance to an unnamed
perennial tributary to Cane Creek near Holbrooks Road in Mecklenburg County, North
Carolina (Figure 1; Photograph Nos. 1-2).
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: 1) Line 1, 4o-inch diameter; and 2) Line 2, 36-inch
diameter. At the above referenced site, bank erosion and streambed degradation has
exposed Line 2 within the stream channel (Photograph No. 3), significantly reducing the
required cover protection level of the pipeline (Appendix A). As required by the U.S.
Department of Transportation (USDOT), CPC must inspect and repair the exposed
pipeline at this location if necessary.
Proposed Activity in Waters of the U.S.
The maintenance activities required to stabilize the stream banks and protect the
existing pipeline will result in temporary disturbance to approximately 6o linear feet of
an unnamed perennial stream located at N350 23.763', W800 49.305'. To ensure the
integrity of the Line 2 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 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 inspection of the pipeline and the completion of the pipeline maintenance
activities, the pipeline will be protected using pre-cast concrete, flexible revetment mats
placed over the pipeline within the existing CPC ROW. This approach includes the use of

geotextile fabric, which is placed between the pipeline and revetment mat (Appendix D).
Specifically, the pre-cast revetment mats will be placed at grade within a 6o4inear foot
segment of the tributary. The pre-cast concrete revetment mats will be used to cover and
protect the pipeline while stabilizing the excavated portions of the streambed. The
quantity of this "fill material" (i.e., revetment mat) below the plane of the ordinary high
water mark will be less than 25 cubic yards.
Additionally, CPC will remove a culvert from the downstream end of the tributary and
replace it with revetment mats to provide a low water crossing for the road. The
proposed maintenance activity will be completed using CPC's Soil Erosion and
Sedimentation Control Plan (Appendix E) to protect the streams from sedimentation.
There will be no disturbance to jurisdictional waters outside of CPC's ROW.

Colonial Pipeline Company - Fxposed Pipe Maintenance WEC Project No. o2-o4i9oi
Cane Greek Tributary Station No. j998+59
General Condition 6 - 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 7 - Water Supply Intakes
The proposed construction does not occur near 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 concrete revetment mats will be "keyed" in to the
upstream end of the disturbed areas 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.
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 - Exposed Pipe Maintenance WEC Project No. 02-o419oi
Cane Creek 7Wbutary Station No. 1998+54
General Condition 15 - Wild and Scenic Rivers
The project sites are not located in or adjacent to a Wild and Scenic River.
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
According to current U.S. Fish and Wildlife Service (USFWS) data, there are four
federally protected species listed as potentially occurring in Mecklenburg County.
Three of the listed plant species are known to occur in similar disturbed habitats
such as roadsides and power lines (Appendix F); however, site disturbance will be
limited to the stream channel and adjacent stream banks which do not provide
preferable habitat for these species. Further, no listed species were observed during
a field inspection of the site conducted by WEC on August 23, 2008. Consequently,
no impacts to federally protected species are expected from this project.
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 ig - 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
total stream disturbance does not exceed the thresholds put forth 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 (i.e., restoration of the pipeline protective
cover). 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.

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.
• 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.

Explain:
B. CWA SECTION 404 DETERMINATION OF JURISDICTION.
There Pick List "waters of the U.S." within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 328) in the review area. [Required]
1. Waters of the U.S.
a. Indicate presence of waters of U.S. in review area (check all that apply):'
? TNWs, including territorial seas
? Wetlands adjacent to TNWs
® Relatively permanent waters' (RPWs) that flow directly or indirectly into TNWs
? Non-RPWs that flow directly or indirectly into TNWs

? Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs
? Impoundments of jurisdictional waters
? Isolated (interstate or intrastate) waters, including isolated wetlands
b. Identify (estimate) size of waters of the U.S. in the review area:
Non-wetland waters: 60 linear feet: 4width (fl) and/or acres.
Wetlands: acres.
c. Limits (boundaries) of jurisdiction based on: Established by OHWM.
Elevation of established OHWM (if known):
2. Non-regulated waters/wetlands (check if applicable)?
? Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional.
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 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.I.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
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 IH.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 HI.B.1 for
the tributary, Section HI.B.2 for any onsite wetlands, and Section HI.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section IH.C 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:

practicable. The revetment mat and will be used to protect CPC's existing pipeline stabilize the
stream bank that is significantly eroded, and provide a low water crossing for future ROW access
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.

required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ? No
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.
I Zone I Impact I I * (ennara fr AA Multiplier Required
1 3 (2 for Catawba)
2 1.5
Total
# Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or.0244, or.0260.

XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The project will not result in impervious
surfaces. BMP's will be incorporated as described under General Condition 9 of the attached
cover letter.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
N/A
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 211.0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ? No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
Upon completion of the project the pipeline should be repaired and protected from future
damage. No other work will be needed
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
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).
