NWP 12 PCN Submittal
Clayton, Johnston County
USACE AID: SAW-2020-00777
WR Project #02190247.00
Dear Mr. Hopper and Mr. Wojoski,
On behalf of the Town of Clayton, we are requesting authorization from the USACE to use NWP
12 for 213 If of temporary stream impacts and 0.082 ac of temporary wetland impacts for
construction of a new sewer force main and gravity sewer to provide conveyance of wastewater
to the new Neuse River Water Reclamation Facility (WRF). We are also requesting an NCDWR
Riparian Buffer Authorization for 7,707 sf of permanent riparian buffer impacts and 17,528 sf of
temporary riparian buffer impacts for construction of the proposed project.
The proposed project consists of the following:
Neuse River WRF - ±79-acres - No Impacts
WRF Access Road - ±10-acres - No Impacts
Little Creek Transmission Lines (new force main and gravity sewer) - ±13-acres - Wetland,
Stream and Riparian Buffer Impacts
The project is located in the Neuse River basin and onsite waters eventually drain to the Neuse
River (HUC: 03020201).
The new sewer force main portion of the project located south of US 70 Business drains to Little
Creek, which flows to Swift Creek and ultimately the Neuse River. The Water Quality
Classification for the Little Creek is C;NSW and the Stream Index Number is: 27-43-12.
The Neuse WRF and new gravity sewer portion of the project located north of US 70 Business
drains to a perennial stream locally known as Sam's Branch, which is a tributary to the Neuse River.
The Water Quality Classification for this section of the Neuse River is WS-IV; NSW and the Stream
Index Number is 27-(38.5).
Proposed Project
The purpose of the proposed project is to replace existing 4.9 MGD capacity provided by the aging
Little Creek Water Reclamation Facility (LCWRF) and prepare for known increasing near -term
demands with construction of the new Neuse River WRF which will provide 6-MGD capacity. This
project is needed because of the LCWRF's aging infrastructure which has exceeded expected

useful life, expiration of its existing contract with the County, and known near term demands for
wastewater treatment.
The proposed project consists of the following:
• Neuse River WRF - Construction of the Neuse River WRF, which will be a 6 MGD facility
constructed at the current site of the pump station that serves as the outfall for the LCWRF
(Lat: 35.664901°N;-78.428642°W), which will be incrementally expanded to 10 MGD to
meet future needs. The LCWRF is being replaced for several reasons, including it being
located within the 100-year flood plain and subject to frequent flooding, it is currently at
maximum capacity and is beyond its life expectancy. The Little Creek WRF is prone to
flooding, and the construction of the Neuse River WRF outside of the 100-year floodplain
will increase the reliability of the Town's treatment capacity and improve provisions for
continuity of service during storm events. The construction of the Neuse River WRF will
not result in impacts to wetlands, streams, or riparian buffers. At this time, only the clearing
and preliminary grading of the WRF site is proposed and impacts will not be required. The
actual design, permitting and construction of the WRF (structures, buildings, piping,
utilities, stormwater management, etc.) will ultimately be determined by the design/build
contractor and therefore a design plan for the WRF is not provided. The WRF early grading
design and sediment & erosion control design is depicted in the construction drawings for
"Access Road/WRF Early Grading Contract" which are attached to this application. Please
note that the replacement/construction of the new outfall into the Neuse River is not part
of this application, as the final design of the outfall and dewatering plan are not complete.
The replacement/construction of the outfall will be permitted by the contractor upon
completion of design.
• NRWRF Access Road - Construction of the access road for the Neuse River WRF. The
proposed access road will be located on the eastern side of the high voltage overhead
power line easement and will provide access from N. O'Neil Street (Lat: 35.669383°N;
Long:-78.441600°W) to the proposed Neuse River WRF. This alignment will provide direct
access to the Neuse River WRF and avoid the use of surrounding subdivision streets during
construction of the Neuse River WRF facility. The construction of the access road will not
require impacts to wetlands, streams, or riparian buffers. The construction drawings for
"Access Road/WRF Early Grading Contract" show the design for the access road.
• Little Creek Transmission Lines Improvements - The Little Creek transmission line
improvements consist of:
o Construction of a new pump station at the LCWRF and 4,595 If of 24" force main
beginning at the current Little Creek WRF (Lat: 35.641237°N; Lat:-78.463271°W)
and running east, ending approximately 130 If east of East Front Street (Lat:
35.643700°N; Long:-78.449439°W).
o Construction of 3,590 If of 24" gravity sewer, 1,067 If of 30" gravity sewer, 5,890
If of 36" gravity sewer, 805 If of gravity sewer and 800 If of 48" gravity sewer
beginning at the terminus of the proposed force main (Lat: 35.643700°N; Long: -
78.449439°W) and running northeast to the proposed Neuse River WRF (Lat:
35.663859°N; Lat:-78.426732°W).
The Town's existing wastewater treatment capacity is 4.9 MGD via its Little Creek WRF (2.5 MGD)
and wholesale contracts with Johnston County (County) for 1.4 MGD and the City of Raleigh (City)
Page 2 of 8

Neuse River WRF - Little Creek Transmission Improvements %� WVithersRavene l
Clayton, Johnston Co.
Our People. Your Success.
for 1.0 MGD. The Town has an existing agreement with the County to provide 1.4 MGD of
pretreated industrial wastewater which will expire in 7/1/2022. The County has made the
decision to not accept any wastewater with characteristics exceeding domestic -strength limits
beginning beyond the expiration of the current contract. With the known increase in industrial
wastewater from existing industrial and commercial customers including Grifols and Novo Nordisk,
the Town must construct the proposed Neuse WRF to handle this demand or else these facilities
could potentially be forced to relocate, resulting in a significant economic impact to the Town and
County from loss of jobs and tax base.
Under the current agreement with the City, the Town conveys domestic -strength wastewater
from the northeastern side of Clayton using the Clayton to Raleigh Pump Station at the City's
NRWWTP. The City has indicated the current contract from 1.0 MGD maximum monthly capacity
could be extended from 2027 to 2032. However, the City is also experiencing growth and with
the growing demand from its customers, the City has indicated that it is not interested in
supporting economic development beyond its retail base in eastern Wake County by expanding
the current agreement with the Town after 2032. Therefore, to assure that the Town can provide
the needed wastewater treatment capacity beyond 2032, the Neuse River WRF is necessary.
The proposed pump station, force main and gravity sewer are necessary to convey wastewater
currently received at the LCWRF to the proposed Neuse River WRF. The proposed force main
line is necessary to transfer wastewater over the natural ridge at East Main Street and into the
proposed gravity sewer line.
The proposed project includes repurposing the existing treated water outfall and proposed gravity
sewer to convey all future raw water flows to the new Neuse River WRF. At the discharge of the
proposed force main to the proposed gravity sewer, there are two other pipes in the ground: one
gravity of the treated effluent for discharge to the Neuse River and one force main conveying raw
sewer to the existing Little Creek WRF. The existing treated water effluent will be repurposed to
convey raw sewage. The existing raw water force main is no longer in use and will be removed as
needed for the proposed project. Approximately 3,110 LF below the force main discharge, another
raw gravity sewer parallels the existing force main and treated effluent gravity sewer. This new
raw sewer line will be dug up and replaced, as is feasible to avoid additional stream impacts, with
a larger capacity line for approximately 5,972 LF. The last portion of the proposed sewer from the
transmission easement to the river will not replace the existing raw sewer but parallel it. This will
keep the proposed gravity sewer out of the floodplain and provide a bypass should repairs need
to be made in the existing sewer. It will be upsized to allow for additional raw water sewer
connections.
There is one gravity sewer that is currently discharging into the exiting Neuse 2 pump station next
to the Neuse River. This sewer will be rerouted to the influent pump station within the new Neuse
River WRF.
The project will be constructed using traditional commercial construction equipment and
trench/backfill construction.
Proiect History
The proposed project required approval by the NCDEQ-Division of Water Infrastructure (DWI)
for State Revolving Fund (SRF) funding. As part of the DWI application process, an Environmental
Impact Document (EID) was prepared by Jacobs and submitted for review and approval. The

project received a FONSI from both the State Clearinghouse and NCDEQ-DWI. Copies of the
FONSIs have been attached to this application, along with the EID.
The USACE field verified the delineation for the Neuse River WRF site on 7/22/2020 (AID: SAW-
2020-00777) as documented in the attached email from Chris Hopper with the USACE dated
12/15/2020. We are requesting issuance of a PJD for the Neuse WRF site in conjunction with
issuance of the NWP 12.
NCDWR issued a buffer determination letter for the Neuse River WRF site on 5/11/2020
(RRO#20-131) which has been attached to this application.
WithersRavenel completed a wetland/buffer delineation for the Neuse WRF Access Road
alignment and Little Creek transmission lines in March 2020. A Preliminary JD Exhibit and
wetland/upland data forms in support of the delineation have been attached to this application.
Please note that we are not requesting issuance of a PJD for this project.
All depicted streams within the Little Creek transmission line alignment were present in the field
and subjectivity to Neuse River Riparian Buffers is conceded and a formal buffer determination
from NCDWR was not requested.
There are no depicted streams within the Neuse WRF Access Road alignment and therefore a
formal buffer determination from NCDWR was not requested.
Proposed Impacts
Construction of the proposed sewer force main and gravity sewer lines will result in 213 If of
temporary stream impacts, 0.082 ac of temporary wetland impacts, 7,707 sf of permanent riparian
buffer impacts and 17,528 sf of temporary riparian buffer impacts.
The proposed 213 If of temporary stream impacts and 0.082 acres of temporary wetland impacts
are necessary for construction of the proposed sewer force main and gravity sewer lines. Impacts
to these features will occur within the existing cleared/maintained easement where possible, as
well as the additional 5 ft of new permanent easement to accommodate the gravity sewer line.
The project will result in 0.082 acres of permanent wetland conversion as a result of
mowing/maintenance of the permanent sewer easement in perpetuity which will permanent
convert forested wetlands to herbaceous wetlands.
The proposed 7,707 sf of permanent riparian buffer impacts will result from clearing of riparian
buffer within the additional 5 ft of new permanent easement which will be mowed/maintained in
perpetuity.
The proposed 17,528 sf of temporary riparian buffer impacts will result from the 10 ft temporary
construction easement necessary for access during construction.
Avoidance and Minimization
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted
so that impacts to wetlands and "waters" could be minimized.
Proposed impacts have been minimized to only temporary impacts necessary for construction of
the new sewer force main and new gravity sewer to convey wastewater flow received at the
current LCWRF to the proposed Neuse River WRF.
Page 4 of 8

Neuse River WRF - Little Creek Transmission Improvements %� WVithersRavene l
Clayton, Johnston Co.
Our People. Your Success.
Wetland, stream, and riparian buffer impacts have been minimized by utilizing the existing
cleared/maintained easement as much as possible. The proposed force main will be located
entirely within existing easement and roads. There are no proposed wetland or stream impacts
necessary for construction of the proposed force main, and only minimal riparian buffer impacts.
The proposed gravity sewer will be located within the existing easement where possible.
However, there is an existing reuse line and gravity sewer line currently in the easement. In order
to meet separation requirements from the existing lines, an additional 5 ft of permanent easement
must be acquired and cleared.
During construction, installation of the sewer line at the stream crossings will be conducted in the
dry using either a bypass pump around option or bypass swale option to bypass stream flow
around the construction areas (see Sheet 116 of Impact Maps). It will be up to the discretion of
the contractor on which method is the best option for each crossing.
All temporarily impacted streams will be restored to preconstruction grades and the banks
stabilized with biodegradable matting. No matting will be placed on the stream beds. The banks
will be seeded with a riparian seed mix to provide temporary stabilization until natural regeneration
of vegetation in the vicinity permanently stabilizes the banks.
Temporarily impacted wetlands within the permanent easement will be restored to natural grade
and seeded with a wetland seed mix to stabilize these areas. The wetlands within the permanent
easement will be mowed/maintained in perpetuity permanently converting these areas to
herbaceous wetlands.
Temporarily impacted wetlands within the 10 ft temporary access easement will be restored to
natural grade and seeded with a wetland seed mix. These areas will not be maintained and will be
allowed to return to forested wetlands.
Temporarily impacted riparian buffers within the 10 ft temporary construction easement will be
restored to natural grade and seeded with a riparian seed mix to restore the riparian buffer, which
will be enhanced by natural revegetation of surrounding vegetation.
Access during construction will occur from uplands where possible and will be restricted to the
project corridor as defined within the impact exhibits. Silt fencing will be installed around all
disturbed areas to prevent loss of sediment into adjacent waters.
Mitigation
All proposed wetland and stream impacts are temporary and therefore mitigation is not proposed.
Additionally, "permanent wetland conversion" impacts are less than 0.10 acres and therefore
mitigation is not proposed.
All proposed riparian buffer impacts are classified as "Allowable Upon Authorization" except for
Impact B21B. Impact B21B is a non -perpendicular sewer crossing resulting from the additional 5
ft of new permanent easement, which will impact 944 sf within Zone 1. Mitigation is required at
a 3:1 ratio for Zone 1 impacts, resulting the requirement of 2,832 sf of riparian buffer mitigation.
The applicant proposes to provide the 2,832 sf of riparian buffer mitigation through purchase of
riparian buffer credits from EBX in one of their various mitigation banks. The Statement of
Availability from EBX for the buffer mitigation has been attached to this application.

During preparation of the EID, Jacobs and WithersRavenel consulted with the USFWS and
NCWRC for determination of the proposed project's potential effects on listed threatened and
endangered species, as well as species proposed for listing under the Endangered Species Act.
Through consultation with USFWS and NCWRC, it was determined that construction of the
proposed Neuse River WRF, access road Little Creek transmission lines would have "No Effect"
on bald eagle, red -cockaded woodpecker and Michaux's sumac. Additionally, it was determined
that the construction of the proposed Access Road and Little Creek Transmission Line would have
"No Affect" on dwarf wedgemussel, Tar River spinymussel, yellow lance, Atlantic pigtoe, Neuse
River waterdog or Carolina madtom as noted on pages 7-40 & 7-41 in the attached "Clayton WRF
Capacity Expansion_ER-EID_CS370431-07_20201007" document.
It was determined that the construction of the new outfall within the Neuse River, which is not
part of the proposed project under this application, may affect but is not likely to adversely affect
dwarf wedgemussel, Neuse River waterdog and Carolina madtom as noted on pages 7-40 & 7-41
in the attached "Clayton WRF Capacity Expansion_ER-EID_CS370431-07_20201007" document.
Through consultation with USFWS and NCWRC it was determined that surveys for Neuse River
waterdog would be conducted and has begun. Additionally, a survey for mussels within the WRF
outfall project area and salvage and relocation if necessary, would be completed prior initiation of
construction of the outfall in the Neuse River.
During the Division of Water Infrastructure's review of the EID, John Ellis with USFWS stated in
an email dated 10/27/2020 that the USFWS concurs with the effect determinations specified in
the EID. The USFWS email has been provided as an attachment to this application.
NCWRC issued a comment letter dated 10/8/2020 during the Division of Water Infrastructure's
review of the EID with their recommendations for the project. All NCWRC's recommendations
were incorporated in the proposed project. NCWRC's comment letter has been provided as an
attachment to this application.
Cumulative Impact Analysis
Secondary impacts to wetlands, groundwater, and water resources are not expected as a result of
the 6-MGD WRF capacity expansion because the expansion is supporting existing and near -term
development already in progress rather than stimulating new development with its associated
impacts.
Cumulative impacts to wetlands, groundwater, and water resources as a result of the proposed
project are not expected to be significant because of water supply watershed protections; Neuse
River watershed stream buffer requirements; and other plans, ordinances, and regulatory
requirements designed to minimize and mitigate those impacts. The NPDES permitting process
accounts for the potential for cumulative impacts to a waterway from the project and other
dischargers.
The potential for secondary impacts to wetlands and streams in the study area will be limited by
the continued implementation of stormwater management and programs, such as the protection
of stream buffers. Increases in both the quality and quantity of stormwater runoff as a result of
development and the addition of impervious area can alter the natural hydrology of an area. As
imperviousness increases, the more impacted surface waters become from contaminants,
increased runoff, flooding potential, and associated stream channel changes. The cumulative
effects of stormwater runoff are evident in the frequent correlation between the location of a

stream and its water quality, where urban streams overall have poorer water quality than rural
streams.
Final development plans must be approved by the Town. USACE and state permitting are also
required for fill-in wetlands or streams. Wetlands adjacent to streams are also protected, in part,
by stream buffer rules and limits on floodplain development. These buffers and wetlands provide
important filtering of runoff, helping to limit SCIs from development to water resources.
Implementation and enforcement of these programs will prevent significant SCIs to wetlands and
water resources in the study area.
The Town's LCWRF currently discharges into the Neuse River. While additional treated effluent
will be discharged, the location is not changing. During the major NPDES permit modification
request process, water quality modeling of the Neuse River was conducted to confirm that this
expanded discharge would not cumulatively impact the Neuse River. Modeling was conducted far
downstream of the outfall location and considered other discharges, including the JCRWWTP, to
consider cumulative impacts. DO levels in the river are projected to be protected. In addition, the
Neuse River watershed has a nitrogen credit trading program to limit nutrient loading into the river
and reduce cumulative impacts to the Neuse River estuary. The Town has purchased the
equivalent of 6 MGD of nitrogen credits. With the granting of speculative limits, the modified
NPDES permit, and the purchase of additional nitrogen credits, SCIs to the Neuse River are not
expected (Appendix B).
Land use activities and growth in the study area could impact groundwater quality by introducing
toxic contaminants into or onto the soil, where they could seep into the water table. Such pollution
can contaminate drinking water wells for communities and individual homes, making them
unsuitable for potable water use. Potential sources of groundwater contamination include:
• Solid waste disposal sites
• Storage or use of hazardous substances
• Poorly designed or maintained septic systems
• Accidental spills
• Leaking underground storage tanks
These potential SCIs resulting from land use activities would likely not be significantly different
from the No Action alternative. Overall, SCIs associated with increases in capacity beyond 6 MGD
are not expected to be significant.
The current request is for 213 If of temporary stream impacts, 0.082 ac of temporary wetland
impacts, 7,707 sf of permanent riparian buffer impacts and 17,528 sf of temporary riparian buffer
impacts (see the attached maps and PCN for details).
Please feel free to call if you have questions or require additional information.
Sincerely,

4h. Explain the purpose of the proposed project:*
The purpose of the proposed project is to replace existing 4.9 MGD capacity provided by the aging Little Creek Water Reclamation Facility (LCWRF) and prepare for known increasing
near -term demands with construction of the new Neuse River WRF which will provide 6-MGD capacity. This project is needed because of the LCWRF's aging infrastructure which has
exceeded expected useful life, expiration of its existing contract with the County, and known near term demands for wastewater treatment.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*

The proposed project consists of the following:
• Neuse River WRF - Construction of the Neuse River WRF, which will be a 6 MGD facility constructed at the current site of
the pump station that serves as the outfall for the LCWRF (Lat: 35.664901 °N;-78.428642°W), which will be incrementally
expanded to 10 MGD to meet future needs. The LCWRF is being replaced for several reasons, including it being located
within the 100-year flood plain and subject to frequent flooding, it is currently at maximum capacity and is beyond its life
expectancy. The Little Creek WRF is prone to flooding, and the construction of the Neuse River WRF outside of the 100-
year floodplain will increase the reliability of the Town's treatment capacity and improve provisions for continuity of service
during storm events. The construction of the Neuse River WRF will not result in impacts to wetlands, streams, or riparian
buffers. At this time, only the clearing and preliminary grading of the WRF site is proposed and impacts will not be
required. The actual design, permitting and construction of the WRF (structures, buildings, piping, utilities, stormwater
management, etc.) will ultimately be determined by the design/build contractor and therefore a design plan for the WRF is
not provided. The WRF early grading design and sediment & erosion control design is depicted in the construction
drawings for "Access Road/WRF Early Grading Contract" which are attached to this application. Please note that the
replacement/construction of the newouffall into the Neuse River is not part of this application, as the final design of the
outfall and dewatering plan are not complete. The replacement/construction of the outfall will be permitted by the
contractor upon completion of design.
• Neuse River WRF Access Road - Construction of the access road for the Neuse River WRF. The proposed access road
will be located on the eastern side of the high voltage overhead power line easement and will provide access from N. O'Neil
Street (Lat: 35.669383°N; Long:-78.441600°W) to the proposed Neuse River WRF. This alignment will provide direct
access to the Neuse River WRF and avoid the use of surrounding subdivision streets during construction of the Neuse
River WRF facility. The construction of the access road will not require impacts to wetlands, streams, or riparian buffers.
• Little Creek Transmission Lines Improvements - The Little Creek transmission line improvements consist of:
o Construction of a new pump station at the LCWRF and 4,595 If of 24" force main beginning at the current Little Creek
WRF (Lat: 35.641237°N; Lat:-78.463271 °W) and running east, ending approximately 130 If east of East Front Street
(Lat: 35.643700°N; Long:-78.449439°W).
o Construction of 3,590 If of 24" gravity sewer, 1,067 If of 30" gravity sewer, 5,890 If of 36" gravity sewer, 805 If of gravity
sewer and 800 If of 48" gravity sewer beginning at the terminus of the proposed force main (Lat: 35.643700°N; Long:
-78.449439°W) and running northeast to the proposed Neuse River WRF (Lat: 35.663859°N; Lat:-78.426732°W).
The Town's existing wastewater treatment capacity is 4.9 MGD via its Little Creek WRF (2.5 MGD) and wholesale contracts with Johnston County (County) for 1.4 MGD and the City of
Raleigh (City) for 1.0 MGD. The Town has an existing agreement with the County to provide 1.4 MGD of pretreated industrial wastewater which will expire in 7/1/2022. The County has
made the decision to not accept any wastewater with characteristics exceeding domestic -strength limits beginning beyond the expiration of the current contract. With the known increase
in industrial wastewater from existing industrial and commercial customers including Grifols and Novo Nordisk, the Town must construct the proposed Neuse WRF to handle this demand
or else these facilities could potentially be forced to relocate, resulting in a significant economic impact to the Town and County from loss ofjobs and tax base.
Under the current agreement with the City, the Town conveys domestic -strength wastewater from the northeastern side of Clayton using the Clayton to Raleigh Pump Station at the
City's NRWWTP. The City has indicated the current contract from 1.0 MGD maximum monthly capacity could be extended from 2027 to 2032. However, the City is also experiencing
growth and with the growing demand from its customers, the City has indicated that it is not interested in supporting economic development beyond its retail base in eastern Wake
County by expanding the current agreement with the Town after 2032. Therefore, to assure that the Town can provide the needed wastewater treatment capacity beyond 2032, the
Neuse River WRF is necessary.
The proposed pump station, force main and gravity sewer are necessary to convey wastewater currently received at the LCWRF to the proposed Neuse River WRF. The proposed
force main line is necessary to transfer wastewater over the natural ridge at East Main Street and into the proposed gravity sewer line.
The proposed project includes repurposing the existing treated water outfall and proposed gravity sewer to convey all future raw water flows to the new Meuse River WRF. At the
discharge of the proposed force main to the proposed gravity sewer, there are two other pipes in the ground: one gravity of the treated effluent for discharge to the Neuse River and
one force main conveying raw sewer to the existing Little Creek WRF. The existing treated water effluent will be repurposed to convey raw sewage. The existing rawwater force main is
no longer in use and will be removed as needed for the proposed project. Approximately 3,110 LF below the force main discharge, another raw gravity sewer parallels the existing force
main and treated effluent gravity sewer. This new raw sewer line will be dug up and replaced, as is feasible to avoid additional stream impacts, with a larger capacity line for
approximately 5,972 LF. The last portion of the proposed sewer from the transmission easement to the river will not replace the existing raw sewer but parallel it. This will keep the
proposed gravity sewer out of the floodplain and provide a bypass should repairs need to be made in the existing sewer. It will be upsized to allow for additional raw water sewer
connections.
There is one gravity sewer that is currently discharging into the exiting Neuse 2 pump station next to the Neuse River. This sewer will be rerouted to the influent pump station within the
new Neuse River WRF.
The project will be constructed using traditional commercial construction equipment and trench/backfill construction.

Supporting Documentation
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:

Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and "waters" could be
minimized.
Proposed impacts have been minimized to only temporary impacts necessary for construction of the new sewer force main and new gravity sewer to
convey wastewater flow received at the current LCWRF to the proposed Neuse River WRF.
Wetland, stream, and riparian buffer impacts have been minimized by utilizing the epsting cleared/maintained easement as much as possible. The
proposed force main will be located entirely within existing easement and roads. There are no proposed wetland or stream impacts necessary for
construction of the proposed force main, and only minimal riparian buffer impacts.
The proposed gravity sewer will be located within the epsting easement where possible. However, there is an epsting reuse line and gravity sewer line
currently in the easement. In order to meet separation requirements from the epsting lines, an additional 5 ft of permanent easement must be
acquired and cleared.
During construction, installation of the sewer line at the stream crossings will be conducted in the dry using either a bypass pump around option or
bypass swale option to bypass stream flow around the construction areas (see Sheet 116 of Impact Maps). It will be up to the discretion of the
contractor on which method is the best option for each crossing.
All temporarily impacted streams will be restored to preconstruction grades and the banks stabilized with biodegradable matting. No matting will be
placed on the stream beds. The banks Will be seeded with a riparian seed mix to provide temporary stabilization until natural regeneration of
vegetation in the vicinity permanently stabilizes the banks.
Temporarily impacted wetlands within the permanent easement will be restored to natural grade and seeded with a wetland seed mix to stabilize these
areas. The wetlands within the permanent easement will be mowed/maintained in perpetuity permanently converting these areas to herbaceous
wetlands.
Temporarily impacted wetlands within the 10 ft temporary access easement will be restored to natural grade and seeded with a wetland seed mix.
These areas will not be maintained and will be allowed to return to forested wetlands.
Temporarily impacted riparian buffers within the 10 ft temporary construction easement will be restored to natural grade and seeded with a riparian
seed mix to restore the riparian buffer, which will be enhanced by natural revegetation of surrounding vegetation.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Access during construction will occur from uplands where possible and will be restricted to the project corridor as defined within the impact exhibits. Silt
fencing will be installed around all disturbed areas to prevent loss of sediment into adjacent waters.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
All proposed wetland and stream impacts are temporary and therefore mitigation is not proposed. Additionally, "permanent wetland conversion' impacts are less than 0.10 acres and
therefore mitigation is not proposed.
6b. If yes, then identify the square feet of impact.

Buffer SOA - Clayton WRF-Little Creek Transmission Line Improvements. pdf 122.25KB
6j. Comments:
All proposed riparian buffer impacts are classified as "Allowable Upon Authorization" except for Impact B21 B. Impact B21 B is a non -perpendicular
sewer crossing resulting from the additional 5 It of new permanent easement, which will impact 944 sf within Zone 1. Mitigation is required at a 3:1 ratio
for Zone 1 impacts, resulting the requirement of 2,832 sf of riparian buffer mitigation. The applicant proposes to provide the 2,832 sf of riparian buffer
mitigation through purchase of riparian buffer credits from EBX in one of their various mitigation banks. The Statement of Availability from EBXfor the
buffer mitigation has been attached to this application.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)

f— Wetland Swale (higher SMNT)
f— Other SCM that removes minimum 30 % nitrogen
W Proposed project will not create concentrated stormwater flow through the buffer

2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
r Yes r No
2b. Does this project meet the requirements for low density projects as defined in 15ANCAC 02H .1003(2)?
r Yes r No
Comments:
At this point, the only proposed impervious area is the access road which will be treated by a vegetated roadside Swale. The only proposed activity currently proposed within the Neuse
River WRF is the early grading of the site, which will not result in impervious area and does not require stormwater management. The actual design, permitting and construction of the
WRF (structures, buildings, piping, utilities, stormwater management, etc.) will ultimately be determined by the design/build contractor and therefore a design plan for the WRF is not
provided. The WRF early grading design and sediment & erosion control design is depicted in the construction drawings for "Access Road/WRF Early Grading Contract" which are
attached to this application.
Once designed, the design/build contractor will be responsible for stormwater management permitting for the Neuse River WRF.

During preparation of the EID, Jacobs and WithersRavenel consulted with the USFWS and NCWRC for determination of the proposed project's
potential effects on listed threatened and endangered species, as well as species proposed for listing under the Endangered Species Act.
Through consultation with USFWS and NCWRC, it was determined that construction of the proposed Neuse River WRF, access road Little Creek
transmission lines would have "No Effect" on bald eagle, red -cockaded woodpecker and Michaux(s sumac. Additionally, it was determined that the
construction of the proposed Access Road and Little Creek Transmission Line would have "No Affect" on dwarf wedgemussel, Tar River spinymussel,
yellow lance, Atlantic pigtoe, Neuse River waterdog or Carolina madtom as noted on pages 7-40 & 7-41 in the attached "Clayton WRF Capacity
Expansion _ER-EID _CS370431-07_20201007" document.
it was determined that the construction of the new outfall within the Neuse River, which is not part of the proposed project under this application, may
affect but is not likely to adversely affect dwarf wedgemussel, Neuse River waterdog and Carolina madtom as noted on pages 7-40 & 7-41 in the
attached "Clayton WRF Capacity Expansion_ER-EID_CS370431-07_20201007" document. Through consultation with USFWS and NCWRC it was
determined that surveys for Neuse River waterdog would be conducted and has begun. Additionally, a survey for mussels within the WRF outfall
project area and salvage and relocation if necessary, would be completed prior initiation of construction of the outfall in the Neuse River.
During the Division of Water Infrastructure's review of the EID, John Ellis with USFWS stated in an email dated 10/27/2020 that the USFWS concurs
with the effect determinations specified in the EID. The USFWS email has been provided as an attachment to this application.
NCWRC issued a comment letter dated 10/812020 during the Division of Water Infrastructure's review of the EID with their recommendations for the
project. All NCWRC's recommendations were incorporated in the proposed project. NCWRC's comment letter has been provided as an attachment to
this application.

Cumulative Impact Analvsis
Secondary impacts to wetlands, groundwater, and water resources are not expected as a result of
the 6-MGD WRF capacity expansion because the expansion is supporting existing and near -term
development already in progress rather than stimulating new development with its associated
impacts.
Cumulative impacts to wetlands, groundwater, and water resources as a result of the proposed
project are not expected to be significant because of water supply watershed protections; Neuse
River watershed stream buffer requirements; and other plans, ordinances, and regulatory
requirements designed to minimize and mitigate those impacts. The NPDES permitting process
accounts for the potential for cumulative impacts to a waterway from the project and other
dischargers.
The potential for secondary impacts to wetlands and streams in the study area will be limited by
the continued implementation of stormwater management and programs, such as the protection
of stream buffers. Increases in both the quality and quantity of stormwater runoff as a result of
development and the addition of impervious area can alter the natural hydrology of an area. As
imperviousness increases, the more impacted surface waters become from contaminants,
increased runoff, flooding potential, and associated stream channel changes. The cumulative
effects of stormwater runoff are evident in the frequent correlation between the location of a
stream and its water quality, where urban streams overall have poorer water quality than rural
streams.
Final development plans must be approved by the Town. USACE and state permitting are also
required for fill-in wetlands or streams. Wetlands adjacent to streams are also protected, in part,
by stream buffer rules and limits on floodplain development. These buffers and wetlands provide
important filtering of runoff, helping to limit SCIs from development to water resources.
Implementation and enforcement of these programs will prevent significant SCIs to wetlands and
water resources in the study area.
The Town's LCWRF currently discharges into the Neuse River. While additional treated effluent
will be discharged, the location is not changing. During the major NPDES permit modification
request process, water quality modeling of the Neuse River was conducted to confirm that this
expanded discharge would not cumulatively impact the Neuse River. Modeling was conducted far
downstream of the outfall location and considered other discharges, including the JCRWWTP, to
consider cumulative impacts. DO levels in the river are projected to be protected. In addition, the
Neuse River watershed has a nitrogen credit trading program to limit nutrient loading into the river
and reduce cumulative impacts to the Neuse River estuary. The Town has purchased the
equivalent of 6 MGD of nitrogen credits. With the granting of speculative limits, the modified
NPDES permit, and the purchase of additional nitrogen credits, SCIs to the Neuse River are not
expected (Appendix B).
Land use activities and growth in the study area could impact groundwater quality by introducing
toxic contaminants into or onto the soil, where they could seep into the water table. Such pollution
can contaminate drinking water wells for communities and individual homes, making them
unsuitable for potable water use. Potential sources of groundwater contamination include:

• Storage or use of hazardous substances
• Poorly designed or maintained septic systems
• Accidental spills
• Leaking underground storage tanks

These potential SCIs resulting from land use activities would likely not be significantly different
from the No Action alternative. Overall, SCIs associated with increases in capacity beyond 6 MGD
are not expected to be significant.

NORTH CAROLINA WILDLIFE RESOURCES COMMISSION
Cameron Ingram, Executive Director
MEMORANDUM
TO: Jaime Robinson, Jacobs
FROM: Gabriela Garrison
Eastern Piedmont Coordinator`s"`"~
Habitat Conservation
DATE: October 8, 2020
SUBJECT: Comments for Environmental Review for the Town of Clayton, Wastewater Treatment
Capacity Expansion.
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject
document. Comments are provided in accordance with provisions of the Fish and Wildlife Coordination
Act (48 Stat. 401, as amended; 16 U.S.C. 661-667e), North Carolina Environmental Policy Act (G.S.
113A-1 through 113A-10; 1 NCAC 25) and North Carolina General Statutes (G.S. 113-131 et seq.).
The Town of Clayton (Town) proposes to expand its wastewater treatment capacity, currently operating at
4.9 million gallons per day (MGD) via the Little Creek Water Reclamation Facility (LCWRF). A phased
approach to meet current and projected demands will occur, beginning with construction of a new 6.0
MGD water reclamation facility on a town -owned site adjacent to the Neuse River. There will be an
anticipated incremental expansion to 10 MGD to meet future needs. The Town's existing LCWRF will
be abandoned, and a pump station will be constructed at that site instead. Additionally, a transmission
main between the new WRF and abandoned LCWRF site will be constructed.
There are records for the following freshwater mussel species, downstream of the project site in the Neuse
River: the federal at -risk and state -endangered, green floater (Lasmigona subviridis); the federal species
of concern and state -threatened, triangle floater (Alasmidonta undulata) and Roanoke slabshell (Elliptio
roanokensis); and the state -threatened, eastern lampmussel (Lampsilis radiata). There are also records
for the federal at -risk and state -special concern, Neuse River waterdog (Necturus lewisi, NRWD), both
upstream and downstream of the proposed project site in the Neuse River.
Personnel from NCWRC have virtually met with consultants representing the Town to give technical
guidance, including the following recommendations, intended to minimize impacts to aquatic and
terrestrial wildlife resources:
1. If mussel surveys in the Neuse River are not conducted to determine species presence, a
salvage and relocation effort by an accredited consultant should be conducted at the proposed
project site on the Neuse River. If NRWD surveys are conducted, the following parameters
should be followed:

Telephone: [phone] • ncwildlife.org

Page 2

Town of Clayton Wastewater Treatment Capacity Expansion
o Trapping should occur in the cooler months of the year when NRWD are most
active.
o If water quality is clear, snorkeling may occur to locate target species through
cobbling and/or searching leaf litter.
o Minnow trapping with bait (chicken livers) in the winter months is a suitable
method. There should be at least ten traps per site — one site upstream of outfall
and one site below outfall for a total of 20 traps. Traps are 10 meters apart from
each other, so they would span a stretch of 200 meters.
If NRWD surveys are not conducted, and species presence is assumed, stringent best
management practices for sediment and erosion control should be implemented to prevent
potential impact, as this species is very sensitive to siltation. In addition, all sediment and
erosion control measures should be checked after significant rain events to ensure they are
still functional.
The National Marine Fisheries Service should be consulted regarding potential moratoria and
impacts related to anadromous fish.
2. Maintain a minimum 100-foot undisturbed, native, forested buffer along perennial streams,
and a minimum 50-foot buffer along intermittent streams and wetlands. Maintaining
undisturbed, forested buffers along these areas will minimize impacts to aquatic and
terrestrial wildlife resources. Wide riparian buffers are helpful in maintaining stream bank
stability. In addition, these buffers provide a travel corridor for wildlife species. Lay down
and staging areas should be located outside wetland areas and at least 100 feet from stream
banks.
3. Measures to avoid or minimize impacts to wetlands should be implemented. In addition to
providing wildlife habitat, wetland areas perform important functions of flood control and
water quality protection. If necessary, crossings should only be at the narrowest point of
wetland areas. In all forested wetlands, clearing should be done by hand.
4. Where applicable, the directional bore (locating utilities beneath the riverbed and avoiding
impacts to the stream and buffer) stream crossing method should be used for utility crossings.
The open cut stream crossing method should only be used when water level is low and stream
flow is minimal. Stream crossings should be near perpendicular (750 to 1050) to stream flow.
Avoid the removal of large trees at the edges of construction corridors. Disturbed areas
should be re -seeded with seed mixtures that are beneficial to wildlife. Avoid fescue -based
mixtures and Sericea lespedeza, as both are invasive, difficult to eradicate and provide little
benefit to wildlife. Native, annual small grains appropriate for the season are preferred and
recommended. Pollinator mixes are commercially available and provide forage and shelter
for numerous species of bees, butterflies, moths and birds. Where feasible, use woody debris
and logs from cleared areas to establish brush piles adjacent to the cleared right-of-way to
improve habitat. If planting native seed mixes is not an option, allowing the corridor area to
re -vegetate into a brush/scrub habitat would maximize benefits to wildlife. For areas adjacent
to residential areas, a native shrub/grass option may also be beneficial.
o Manage non-native, invasive species by pretreating the project sites prior to
construction, preventing spread during construction, and controlling non-native,
invasive species after construction is complete.

Town of Clayton Wastewater Treatment Capacity Expansion
Minimize corridor maintenance and prohibit mowing between April 1 and October 1 to
minimize impacts to nesting wildlife. Create a maintenance schedule that incorporates only a
portion of the area (one third of the area, for example) each year instead of the entire project
area every 3 to 4 years. Pesticides (including insecticides and herbicides) should not be used
for maintenance of right-of-ways within 100 feet of perennial streams and 50 feet of
intermittent streams, or within floodplains and wetlands associated with these streams.
Sediment and erosion control measures should be installed prior to any land -disturbing
activity. The use of biodegradable and wildlife -friendly sediment and erosion control devices
is strongly recommended. Silt fencing, fiber rolls and/or other products should have loose -
weave netting that is made of natural fiber materials with movable joints between the vertical
and horizontal twines. Silt fencing and similar products that have been reinforced with
plastic or metal mesh should be avoided as they impede the movement of terrestrial wildlife
species. Excessive silt and sediment loads can have detrimental effects on aquatic resources
including destruction of spawning habitat, suffocation of eggs and clogging of gills.
The NCWRC encourages the applicant to consider additional measures to protect aquatic and terrestrial
wildlife species in developing landscapes. The NCWRC's Guidance Memorandum to Address and
Mitigate Secondary and Cumulative Impacts to Aquatic and Terrestrial Wildlife Resources and Water
Quality (August 2002; http://www.ncwildlife.org/Portals/0/Conserving/documents/2002_
GuidanceMemorandumforSecondaryandCumulativeImpacts.pdf) details measures to minimize secondary
and cumulative impacts to aquatic and terrestrial wildlife resources; in addition, the Green Growth
Toolbox (hops://www.ncwildlife.org/Conservin /g Programs/Green-Growth-Toolbox) provides
information on nature -friendly planning that discusses how to address growth while concurrently
conserving priority terrestrial and aquatic habitat.

Please give a brief project description below.*

The proposed project consists of construction of:
1) a new Water Reclamation Facility (WRF) that will replace the existing
Little Creek WRF which is undersized and outdated and will be
decommissioned. The proposed WRF site will be located at the existing
pump station along the Neuse River.
2) an access road to the new WRF site from North O'Neil Street along an
existing overhead high tension powerline easement
3) a newsewer line to convey flowfrom the existing Little Creek WRF within
the existing force main easement from the Little Creek WRF to the existing
pump station.
4) Upgrades to the existing outfall pipe within the Neuse River.
There are no anticipated wetland, stream or riparian buffer impacts for the
construction of the WRF site or the access road. There will be temporary
wetland and stream impacts for construction of the new sewer line within
the existing easement. The project is anticipated to be permitted under
either the existing NWP 12 or the proposed NWP-D.
An EA has been prepared for the project and is currently being reviewed
by NCDWI for approval.
