Re: PreConstruction Notification for Nationwide Permit No. 12
East Clayton and Wilson's Mills Sewer Line Projects (Phase I & Phase II)
Clayton, Wilson's Mills, and Smithfield, Johnston County, North Carolina
F&R Project No. H66-5104E
Mr. Brown:
Froehling & Robertson, Inc. (F&R) has been contracted by McKim and Creed PA to perform
wetland consulting services on behalf of Johnston County for the above-referenced project sites.
Johnston County is proposing to expand two separate sewer lines to improve municipal
wastewater services for existing residential and commercial properties, as well as reduce system
operation and maintenance costs. The two sewer line expansion projects will also provide safe
and reliable wastewater system capacity in surrounding areas.
F&R is submitting PreConstruction Notifications (PCN) to obtain Nationwide Permit No.12 for
each of these separate projects, referred to as Phase I and Phase II of the East Clayton and
Wilson's Mills Sewer Line. The Phase I and II designation was selected in order to provide
continuity with the County's design team and because the funding was allocated simultaneously
for the two projects.
Although the two projects are known as Phase I and Phase II, each Phase has independent utility
and can be constructed absent the construction of the other Phase. In fact, Phase I will be
constructed even if Phase II is not executed and Phase II will be installed even if Phase I is not
built.
Phase I will consist of three separate segments. The first of these, Phase I-A, will install a new
sewer line that begins at the existing force main on the north side of NC Highway 42 at the
Neuse River; the line continues south to Gully Mill Creek; southwest to Glen Laurel Drive;
east/southeast to Powhatan Road; west/southwest to a railroad crossing; southeast/south to North
Tech Park Drive; and west/southwest to US Highway 70 Business (70-BUS). After crossing to
the west side of 70-BUS, the sewer line will connect to an existing force main. Site vicinity maps
(Figure 1), USGS topographic maps (Figures 2a & 2b), and NRCS Soil Survey maps (Figures 3a
& 3b) are included with the PCN.

SIMCf
Ietll
Phase I-B begins at the existing Wilson's Mills Elementary School Pump Station; continues
south to an unnamed tributary of Poplar Creek; south across US Highway 70 Bypass (70-BYP)
to Twin Creek Road; west to the existing Wilson's Mills Pump Station, east to Swift Creek
Road; and southwest to 70-BUS. After crossing to the west side of 70-BUS, the sewer line will
connect to an existing force main, as well as to a new force main that comprises Phase I-C (see
below). Wastewater from Phase I-B will be able to be directed to either the existing force main
or the new force main (Phase I-C). Site vicinity maps (Figure 4), USGS topographic maps
(Figures Sa & Sb), and NRCS Soil Survey maps (Figures 6a & 6b) are included with the PCN.
Phase I-C begins at the terminus of Phase I-B at 70-BUS and continues southeast along 70-BUS
to the east side of the Neuse River in Smithfield. The new sewer line will parallel the existing
force main along 70-BUS, thereby minimizing impacts to wetlands, streams, and open waters.
Site vicinity maps (Figure 7), USGS topographic maps (Figures 8a & 8b), and NRCS Soil
Survey maps (Figures 9a & 9b) are included with the PCN.
Phase II will install a new sewer line that begins on the west side of 70-BUS to the north and west
of the intersection with North Tech Park Drive; the line continues south along 70-BUS; and
southeast to the southeast corner of the intersection of Swift Creek Road and 70-BUS. At this point,
the sewer line will connect to an existing force main, as well as to a new force main that
comprises Phase I-C. Wastewater from Phase I-A will be able to be directed to either the existing
force main or the new force main (Phase II). Site vicinity maps (Figure 10), USGS topographic
maps (Figures l la & 12b), and NRCS Soil Survey maps (Figures 13a & 13b) are included with
the PCN.
As described above, the two projects referred to as Phase I and Phase II of the East Clayton and
Wilson's Mills Sewer line would be constructed absent the construction of the other project.
Consequently, the two projects satisfy the independent utility test of the USACE and each
constitutes a single and complete project.
As a result of independent utility, F&R is requesting separate Nationwide Permit No.12 for
Phase I and Phase II and completed PCN forms are attached for each project. Please contact us if
you have any questions or if additional information is required.
Respectfully Submitted,
FROEHLING & ROBERTSON, INC.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
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.
Avoidance and minimization of direct impacts was a rimary concern recognized throughout
proiect planning, resulting in development and consideration of numerous alternative desi ng s _
Specific measures incorporated to avoid proposed impacts in the proposed design include a~
locating sewer line in existing DOT right-of-way and parallel to an exsistin~ sewerlin and
sewerline easement; b) installation of sewer line below existing culverts (UT Cooper Branch UT
Reedy Branch,; and c) installation above existing culverts (UT Reedy Branch)
Specific measures incorporated to minimize impacts in the proposed design include 1)
pemendicular crossings of channels where avoidance was not practical (e ~ directional drilling
cost prohibitive, use of previously impacted existing easement not possible• installation of sewer
line above or below existing culverts not ractical)• stabilization of excavated areas with stone
or rip-rap and geotextile fabric• compliance with conditions of WOC #3374 and appropriate best
management practices.
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
Page 6 of 10

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
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Mitigation is not required for this project.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at htta://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please

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:
The proposed force main is intended to provide a safe and reliable sewer system for
existing residential and commercial land uses in the project service area, as well as, for future
growth in the area. The proposed project will also reduce overall system operation and
maintenance costs. The project will provide additional safe and reliable wastewater system
capacity in areas surrounding the project site. The project service area is an area of heavy r
within Johnston County. The rate of growth in the project planning area is anticipated to impact
current land use with planned developments. This development trend is likely to continue with or
without this project, however, this project may hasten this trend. The majority of new
development within this area is anticipated to be residential.
Indirect and cumulative water qualitypacts may accrue from future development. It is
presumed that future development will be in accordance with Johnston County Land Use
Ordinances,NCDENR Sediment and Erosion Control Plans as well as the Neuse River Basin
Riparian Buffer Rules. However, loss of riparian forests and increased impervious surface area
reduces rainfall infiltration, increases soil erosion, and concentrates pollutants. Urban stormwater

eroded soil. and animal waste. Peak stream flows are typically increased causing stream bank
erosion, channel destabilization decradation of in-stream habitat and increased magnitude and
frequency of floodinc. Conversely the increase in impervious surface area and soil com action
that occurs with development can reduce infiltration rates which may in turn reduce base stream
flows durinc dry weather adversely affecting aquatic habitat
Sediment, nutrients and other forms of pollution from agricultural sources will likely decline
as the area develops but urban stormwater impacts will likely increase The installation of the
sewer line will allow for future sewer network expansion within the project service area Such an
expansion would permit the abandonment of individual se tic systems within the basin which
could have a direct positive impact on basin-wide water quality
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).
No constraints are anticipated

FINDING OF NO SIGNIFICANT IMPACT (FNSI)
Article 1, Chapter 113A of the North Carolina General Statutes requires an action to be subject to
the requirements of the North Carolina Environmental Policy Act (NCEPA) if it involves the
expenditure of public funds and a potential impact is anticipated to the environment. The project
has been evaluated for compliance with the NCEPA and determined to be a major agency action
which will affect the environment.
Project Applicant: Johnston County
Project Description: The proposed Johnston County, North Carolina wastewater treatment
and transmission facilities improvements project includes the phased
upgrade and expansion of an existing 7.00 MGD wastewater
treatment plant to 13.5 MGD, the constntction of new wastewater
transmission facilities, and the expansion of the County's existing
reclaimed water system. This project will serve portions of Johnston
County, North Carolina and the Towns of Smithfield, Selma, Four
Oaks, and Pine Level.
Project Number. CS370560-09
Project Cost: $15,805,000
State Revolving Fund
Loan: $ 15,000,()0()
Local Funding: $805,000
The review process indicated that significant adverse environmental impacts should not occur if
mitigative measures are implemented, and an environmental impact statement will not be
required. The decision was based on information in the engineering report and reviews by
governmental agencies. An environmental assessment supporting this action is attached. This
FNSI completes the environmental review record, which is available for inspection at the State
Clearinghouse.
No administrative action will be taken on the proposed project for at least thirty days after
notification that the FNSI has been published in the North Carolina Environmental Bulletin.
