Thanks Stephanie and Lyle for your review. I will go back through and check the quantities but wanted to let you both
know that the Neuse crossing is likely to get pulled from the project so will be coming back with some revised plans with
the crossing excluded.

Mr. Aycrigg,
I have reviewed the above referenced project and need the following comments/questions addressed to evaluate the
proposed activities.
1) The requested NWP 12 authorizes activities required for the construction, maintenance, repair, and removal of
oil and natural gas pipelines and associated facilities in waters of the United States. It appears the proposed
activities are more applicable to and may be authorized under NWP 58 (attached). Please review NWP 58 and
conditions and advise if you would like to proceed under NWP 58. Yes please this was the original intent.
2) The referenced "purpose and need" document is not located in the file. Please provide the "purpose and need"
document that details the purpose, project description and avoidance and minimization. Note: There may be
additional comments after review of the "purpose and need" document. Please see attached.
3) Please provide a brief statement explaining the proposed compensatory mitigation plan. Mitigation is proposed.
Please see attached SOA.
4) It appears that the proposed permanent wetland impacts (easement impacts) are conversion of forested
wetlands to herbaceous wetlands and not a result of permanent fill? Please confirm. Correct.
5) It appears that the temporary crossing of the Neuse River and two crossings of Perry Creek will include the
introduction of riprap fill to the toe of slope. Permanent fill installed below the OHWM would be considered a
4

permanent stream impact. Based on the plans it appears the riprap will match the pre -construction stream
elevation and contours and therefore would be considered permanent impacts resulting in no functional loss. If
this is the case please update the PCN and exhibits accordingly. The applicant does not propose riprap below the
OHWM.
6) The location of the Neuse River crossing is located approximately 6 river miles upstream of NOAAs critical
habitat designation and NCWRCs Anadromous Fish Spawning Inland Waters Area. The extent of these areas end
at the former location of the Milburnie Dam, which since has been removed. In order to verify compliance with
General Condition 3 & 18 coordination/consultation with NOAA and NCWRC will be necessary. As the Neuse
River crossing has been removed from the project, this effort is not needed.
a. I have attached the Section 7 checklist which will need to be filled out in order to consult with NOAA.
7) It appears the stream width at S5 is less than the 334 feet listed in the PCN. Please update the stream width on
the PCN. The tables have been updated to reflect the updated plan set.
Please let me know if you have any questions/concerns. It may be helpful to set up a phone call to discuss the Section 7
process if you would like to.

Purpose & Need/Avoidance & Minimization Statement for Proposed Wetland and Stream Impacts
Perry Creek Neuse River Interceptor Project
Raleigh, Wake County, North Carolina
F&R Project No. 66V-0170-1000
PURPOSE AND NEED
The proposed sewer line replacement project is located in northern Wake County and generally
follows Perry Creek from Capital Boulevard east to east of Perry Creek Road, then turns south,
crosses SR 401 and continues to the Neuse River where a siphon is proposed. The proposed project is
intended to address existing and future system wet -weather hydraulic deficiencies by upgrading
12,400 linear feet (LF) of a gravity outfall consisting of 24" sewer pipe, comprised of approximately
6,650 LF of direct replacement and 5,750 LF of relocated pipe. This Purpose and Need statement
provides general project information and describes the design aspects utilized to reduce and
eliminate wetland and stream impacts to the maximum extent practicable.
The project has had two riparian stream buffer calls; one was completed July 6, 2018 that covered
the alignment (NBRRO #18-211) and a second call was completed March 4, 2020 (RRO #20-009) that
covered access roads that may be used to for construction. Additionally, a Preliminary Jurisdictional
Determination was completed October 10, 2018 (see included approval email from Mr. Ross Morton,
PWS).
The applicant has conferred with the US Fish and Wildlife Service (USFWS) with regard to threatened
and endangered species for this project. The USFWS has recommended a salvage and relocation
effort be completed for the Neuse River siphon. Three Oaks Engineering has been contracted to
complete the salvage and recovery effort. No other concerns have been raised with regard to other
species besides mussels in the Neuse River.
AVOIDANCE AND MINIMIZATION
Project construction will require excavation within the boundaries of the project as soil is temporarily
side cast during construction/installation of the sewer line. In wetland areas, upon completion of
installation, side cast soil material will be approximately returned to its original location to maintain
the preconstruction grade elevation. Once grade is reestablished in the temporary impact areas, the
restored areas will be seeded with appropriate native grasses as referenced in the Temporary and
Permanent Seeding Specs published by the North Carolina Department of Environmental Quality.
This reference is included with the PCN and will be included with the bid package for the job. Soil
erosion during construction will be minimized by following a DEQ-approved Erosion and
Sedimentation Control Plan, submitted to the DEQ at least 30 days prior to construction. A number of
steps were taken during the planning stages of this project in an effort to substantially reduce and, in

some cases, eliminate wetland and stream impacts; however, the alignment design is largely based
on utilizing the existing corridor and gravity flow for the sewer pipes. Some of the specific measures
and considerations taken to avoid and minimize impacts to streams and wetlands include:
• Realignment of the sewer location where practical to avoid placing permanent
aboveground features such as vents and manholes in wetlands.
• Natural vegetated buffers being maintained where possible.
• Consideration of practices such as aerial crossings, bore and jack, etc.
• Lay -down and staging areas located outside of wetlands and greater than 100' from
streams
• Limiting areas of disturbance within wetlands where feasible to reduce construction
footprint
• Utilizing super silt fence and other enhanced erosion and sediment control measures to
prevent silt and sediment from entering wetlands.
• Reducing permanent maintained easement corridor where feasible.
• Completion of a salvage and recovery effort for mussels that may occur in the vicinity of
the Neuse River siphon.
The planning measures listed above have been taken to effectively reduce the amount of wetland
and stream impacts to the greatest extent practicable. To address potential impacts to aquatic
species, the USFWS recommends all practicable measures be taken to avoid adverse impacts,
including sediment and erosion control measures, maintaining natural vegetated buffers on streams
adjacent to the project site. All practicable measures will be taken to avoid adverse impacts to
aquatic species. Examples of these measures include installing silt fence tree protection fencing,
super silt fence, rock check dams, silt sack inlet protection, temporary pump -around for streams,
concrete washouts and temporary gravel construction entrances. Erosion and sedimentation controls
will be installed and maintained between the construction site and nearby down -gradient surface
waters. An erosion and sedimentation control plan will be submitted to the NC Land Quality Section
for approval of a NPDES Stormwater prior to construction and is pending review and approval.
The USFWS may also recommend directional drill methods for stream and wetland crossings;
however, directional drill is not appropriate for this project. The project entails a long, relatively flat
sewer outfall with little elevation difference between the upstream and downstream portions of the
project. Therefore, directional drill of stream or wetland crossings is not practical due to the
challenges of maintaining grade with horizontal directional drill. Dips or sags could easily form
resulting in significant constructability issues or worse, operability issues if left unresolved. As
recommended, open cut stream crossing methods will be utilized when water levels are low and
stream flow is minimal, and pump -around methods will be used where applicable. Negative impacts
to protected aquatic species or aquatic resources are not anticipated as a result of this project. It is
our opinion that these efforts satisfy the requirement to avoid wetland and stream impacts where
possible and reduce impacts where necessary to the maximum extent practicable.
W.K. Dickson 2 Perry Creek Interceptor
F&R Project Number: 66v-0170-1000 April 2021

As recommended by USFWS, natural vegetated buffers on all streams and creeks adjacent to the
project site will be protected to the maximum extent practicable. Reasonable care will be taken
during construction to avoid damage to vegetation not located in the easements. Trees that are not
selected for removal within the proposed alignment and trees located outside of the project
boundary will be protected from unnecessary cutting, breaking or skinning of roots; skinning and
bruising of bark; smothering of trees by stockpiling construction materials or excavated material
within the drip line; excessive foot and vehicular traffic including parking of vehicles within drip line
during construction.
SUMMARY
The Purpose of the Perry Creek Neuse River Interceptor project, as described above, is to address
wet -weather hydraulic deficiencies in the existing sewer line system, protect the environment by
providing a means of replacing septic systems areas that will eventually fail, and provide for future
growth.. This PCN submittal addresses the general and regional conditions of Nationwide Permit 58
and ensures aquatic resources are protected.
F&R on behalf of W.K. Dickson respectfully requests review and approval of this NWP 58 verification
so that bidding and construction of the project can proceed without delay.
Sincerely,
