F&R Project No. H66-5063E
Ms. Chapman:
Froehling & Robertson, lnc. (F&R) is submitting this Pre-Construction Notification (PCN) to the
North Carolina Division of Water Quality (NCDWQ) for written concurrence for allowable
impacts to "Waters of the United States". F&R is sending a courtesy copy to the US Army Corps
of Engineers (USAGE) as the project is in accordance with Nationwide Permit No. 12 and
written concurrence from the USAGE is not required. F&R has been contracted by McKim &
Creed PA to perform wetland consulting services on behalf of the Town of Clayton for the
above-referenced project site located in Johnston County, North Carolina within the Neuse River
Basin.
Specifically the project site is located on the "Clayton, NC" USSG topographic map, page 1 of
the printed soil survey of Johnston County, NC, and page 40, grid D4 of the North Carolina Atlas
and Gazetteer. The relevant portion USGS topographic map and the Soil Survey of Johnston
County, NC with the project site location marked are attached to the PCN. The project as
proposed will extend west an approximately three mile long gravity sewer line (GSL) from an
existing waste water treatment facility located at the confluence of Sam's Creek and the Neuse
River. A portion of the proposed GSL is located within an existing utility easement parallel to an
existing force main (FM).
The Town of Clayton is proposing the following impacts:
- Three parallel Zone 2 buffer impacts (less then 150 Linear feet) within an existing
easement adjoining Sam's Creek;
- Eight stream crossings (120 linear feet of impacts to six intermittent streams and 40 linear
feet to two perennial streams all of which are unnamed tributaries to Sam's Creek,. Five
of the crossings are perpendicular, two are 71 degree near-perpendicular, and one is non-
perpendicular, please see the below explanation;
- One isolated wetland (.007 acers)

Parallel impacts to Zone 1 of the Riparian Buffer were completely avoided. Parallel impacts to
Zone 2 were avoided and minimized to the extent practical by placing the GSL within the
existing utility easement. However the existing easement is already located within zone 2. The
GSL is not being proposed within the buffer. Impacts to the buffer are a result of clearing for
construction and will be temporary. Placing the GSL outside of the existing easement would
cause the GSL to diverge greatly from the existing easement and increase the total disturbed area
and easement requirements. It would also create an unusable piece of property between the new
and existing easement creating no practical alternative to placing the line in the existing
easement.
Perpendicular impacts resulting from eight stream crossing were also unavoidable. Of the eight
stream crossings listed on the PCN with a total stream impact of 160 ft, 7 crossings with a total
stream impact of 140 ft have been classified as Neuse Riparian Buffer Impacts by the NCDWQ
Raleigh Regional Office (NCDWQ RRO). One crossing listed on the PCN has been classified by
the USAGE Raleigh Regulator Office (USAGE RRO) as a "Water of the United States" but not
classified as a Neuse Riparian Buffer Impact by the NCDWQ RRO. Five stream crossings are
within the definition of "perpendicular crossing". However, staying within the existing easement
and minimizing these buffer impacts requires three of the crossings to be less then 75 degrees. It
is F&R's understanding based on conversations with DWQ staff that staying within an existing
easement and avoiding additional and unnecessary buffer impacts is preferred to making the
crossings parallel. Crossing the stream between a 75' and 1.05' angle, would again require the
new GSL to diverge greatly from the existing easement and increase the total disturbed area and
easement requirements. It would also create an unusable piece of property between the new and
existing easement creating no practical alternative to placing the line in the existing easement.
Wetland impacts were also avoided and minimized throughout the length of the project.
However, one isolated wetland impact is unavoidable due to the placement of the existing utility
easement with in the wetland.
Stream crossings will consist of a "cut and fill" type crossing and will be perpendicular to the
surface water of the stream. Once the GSL is installed, the stream channel and banks shall be
returned to the pre-existing grade. The maintained easement will be 10 feet wide.
In accordance with Cumulative Impacts and the 401 Water Quality Certification and Isolated
Wetland Programs Draft Internal Policy, Johnston County and the Town of Clayton are
committed to requiring on-site storm water management measures (such as level spreaders, bio-
retention, or constructed wetlands) for development when parcels adjacent to these sewer line
improvement corridors are developed.
It is F&R's understanding that the three parallel impacts to Zone 2 of Riparian Buffers are
"Allowable" IAW 15A NCAC 02b .0233 (6) and require written concurrence IAW North
Carolina General 401 Water Quality Certification 3625.
It is F&R's understanding that the seven perpendicular stream crossings that disturb less than
150 linear feet are "Allowable" IAW 15A NCAC 02b .0233 (6) and require written concurrence
IAW North Carolina General 401 Water Quality Certification 3625.

RE: Sam's Creek Interceptor -Stream Crossing Angles
Dear Mr. Burkhardt:
ENGINEERS
SURVEYORS
M&C 0136-0029 (40)
Per your request, we have prepared the following list of stream crossing angles
using the same naming system. as the original PCN application:
Stream Name Crossing An le
A 44°
B 71°
C 75°
F $1°
I 71°
J 86°
L 105°
O 75°
Based on GC 3374 and NW 12 permitting criteria, sanitary sewer crossings of
streams A, B and I do not meet the requirement of crossing a water course at an
angle of between 75° and 105°. We request written concurrence for these
crossing for the following reasons:
• Stream A -The portion of the proposed gravity sewer that crosses
stream A will be installed along an existing permanent sanitary sewer
easement. In order to cross the stream between a 75° and 105° angle, it
would have required the new gravity sewer line to diverge greatly from
the existing easement. and increase the total disturbed area and easement
requirements. It would also create an unusable piece of property
between the new and existing easement.

Mr. Chris Burkhardt

• Stream B -The crossing of stream B is made under the same
circumstances as Stream A.
• Stream I -The proposed gravity sewer intersects the west stream bank at
an angle of 75° and the east stream bank. at an angle of 67°. The angle of
71° shown above is an average of these two angles. Since the stream
meanders in this area, we were not able to achieve a 75° angle (average)
without significantly increasing the overall disturbed area or incurring a
parallel buffer impact along Sam's Creek.
If you have any question or concerns, please don't hesitate to contact us.
Sincerely,
McKIM & CREED, P.A.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
I . Provide a written description of the proposed impacts:
Based on consultation with representatives of the USACE and NCDWQ, temporary impacts to
seven buffered stream crossings and one isolated wetland are anticipated as a result of this
project. One stream (feature `B") has been claimed jurisdictional by the USACE but is not
subject to the NCDWQ buffer rules (not mapped on soil survey or most recent topographic map).
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

Total Wetland Impact (acres)
3. List the total acreage (estimated) of all existing wetlands on the property: 310.0
4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary
impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam
construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib
walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed,
plans and profiles showing the linear footprint for both the original and relocated streams
must be included. To calculate acreage, multiply length X width, then divide by 43,560.

local stormwater requirement, etc.): N/A
Current land use in the vicinity of the pond: N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
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.
Please see the attached cover letter. Indirect and cumulative impacts have been avoided and
minimized to the extent practical during project planning and design. The sewer line begins at
the confluence of Sam's Creek and the Neuse River at an existing Waste Water Treatment
Facility. The first portion of the sewer line (almost 1/3 of the total length) parallels an existing
sewer line within the existing easement in order to minimize new disturbance.
The remaining portion of the sewer line parallels Sam's Creek. In order for the rg avity sewer
line to work properly and be installed in the most cost effective way, the alignment needs to
parallel Sam's Creek as close as possible, causing unavoidable impacts to streams and wetlands.
These impact lengths are minor compared to the overall length of the sewer.
The proposed sewer line will not impact the Zone 1 buffer along Sam's Creek. Impacts to
Zone 1 of the Neuse River Basin Buffer will be due to perpendicular crossings of existing
tributaries of Sam's Creek.
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
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
Page 6 of 10

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/newetlands/strm~~ide.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.
Please see the attached cover letter mitigation is not anticipated 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
(9I9) 715-0476 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 http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount ofNon-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ® No ^
Page 7 of 10

2. If yes, does the project require preparation of an environmental document pursuant to the

Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
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® 15A NCAC 2B .0233 (Meuse) 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.

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.
Please see the attached Cover Letter Buffer mitigation is not required.
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. Impervious surfaces are not proposed for the project (excludinP manholes).

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.
The proposed project is a sewer line, designed to increase available capacity for current and
future development within the area of the project site. Waste carried by the proposed sewer line
would be treated in a local wastewater treatment facility according to state and local regulations
prior to being discharged into the Neuse River.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .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:
The proposed sewer line is intended to provide a safe and reliable sewer system for future
growth in the project service area as well as for existing residential and institutional land uses in
the area. The proposed sewer line will also reduce overall system operation and maintenance
costs. Heav~~rowth in the project planning area is anticipated to impact current land use with
planned developments associated with the growth of the town of Clayton. This development may
not be feasible without centralized wastewater collection. The majority of new development is
anticipated to be residential.
Indirect and cumulative water quality impacts may accrue from future development. It is
presumed that future development will be in accordance with Johnston County's Land Use Plan,
NCDENR Sediment and Erosion Control Plans. and the Neuse River Basin Riparian Buffer
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 PSA. Such an expansion
would permit the abandonment of individual septic systems within the basin, which could have a
direct, positive impact on basin-wide water quality
In accordance with Cumulative Impacts and the 401 Water Quality Certification and Isolated
Wetland Programs Draft Internal Policy, Johnston County and the Town of Clayton are
committed to requiring on-site storm water management measures (such as level spreaders, bio-
retention, or constructed wetlands) for development when parcels adjacent to these sewer line
improvement corridors are developed.

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).
