Re: Minor Modification of the Non -Discharge Permit for the Holly Ridge WWTP (WQ0019907)
Onslow Water and Sewer Authority
Dear Reviewer:
The Onslow Water and Sewer Authority (ONWASA) currently operates the Holly Ridge Wastewater
Treatment Plant (WWTP) and the Summerhouse WWTP. The Holly Ridge WWTP currently discharges to
a sprayfields site. ONWASA is building a new 1-MGD Southeast Water Reclamation Facility (WRF) and
converting the sprayfields site to an infiltration basin site. Treated effluent from the new Southeast WRF
will normally be discharged to 26 new infiltration basins. However, there will be an option to pump treated
effluent from the new WRF to the infiltration basin pump station wet well at Summerhouse via a new 8-inch
force main. This will allow discharge of treated effluent to the existing Summerhouse infiltration basins at
a future date. This force main is to be installed in a separate Transmission contract (ONWASA SE Service
Area Wastewater Capacity Improvements: Contact 1). Contract 1 construction is not being permitted under
the recently submitted Holly Springs major non -discharge permit application. Based on discussion with
Non -Discharge Unit personnel, the new 8-inch treated effluent return line constitutes a minor modification
to the existing Holly Ridge WWTP Non -Discharge permit.
To that end, on behalf of ONWASA we are sending this application for a minor modification to the Holly
Ridge WWTP non -discharge permit (WO0019907). We desire permission to construct the 8-inch force
main under the minor permit; operation of the line would be part of the major modification to the non -
discharge permit or in a modification to the Summerhouse WWTP permit. The application package includes
the Wastewater Irrigation Systems Checklist as well as the following sections:
A. Cover Letter & Project Narrative
C. Wastewater Irrigation Systems (WWIS 06-16) Form as well as attachments
D. Property Ownership Documentation
I. Engineering Plans (for the 8-inch line)

Detailed Project Narrative
DETAILED PROJECT NARRATIVE
Holly Ridge Non -Discharge Permit Minor Modification,
WQ0019907
Overview
The Onslow Water and Sewer Authority (ONWASA) is currently designing capacity improvements in their
Southeast Service Area. The capacity improvements are to be constructed in three bid contracts as listed
below:
Contract 1: Transmission. Two new pump stations and connecting force mains would be constructed
under this contract. The new Holly Ridge pump station, located at the existing Holly Ridge WWTP, will
pump wastewater flows from the Holly Ridge collection system to the new Summerhouse pump station.
The new Summerhouse pump station, to be constructed at the existing Summerhouse WWTP, will pump
Holly Ridge flows, Summerhouse subdivision flows, and future subdivisions flows to the new Southeast
Water Reclamation Facility (WRF). The transmission infrastructure in Contract 1 is to be permitted in the
Fast Track program under the North Carolina Department of Environmental Quality (NCDEQ). Contract
1 also includes installation of a new 8-inch diameter treated effluent return line to transport treated effluent
from the new WRF effluent pump station to the existing Summerhouse WWTP reclaimed water pump
station wet well. The return line will be installed parallel to the new 16-inch raw wastewater line pumping
wastewater from the new Summerhouse Pump Station to the new SE WRF. The new 8-inch line is to be
installed under Contract 1 as the 16-inch and 8-inch would be installed parallel to each other and
construction of these two lines simultaneously minimizes the environmental impact (versus separate
installation of the lines) and is most efficient from a construction time and cost perspective. Figure I is a
vicinity map for Contract 1. Figure 2 depicts the new 8-inch treated effluent transfer line route. Figure 3
is a topographic map for the 8-inch line route.
Contract 2: WWTP. Construction of a new 1.0-MGD Southeast Wastewater Reclamation Facility (WRF)
at the existing Holly Ridge spray field site.
Contract 3: Infiltration Basins. Construction of twenty-six (26) new infiltration basins at the existing
Holly Ridge spray field site.
Infrastructure under Contracts 2 and 3 above are to be permitted under a separate Holly Ridge WWTP
Major Non -Discharge permit modification. Contract 2 includes the treated effluent transfer pumps and thus

SECTION A
Detailed Project Narrative
this is included in the major permit modification. This major permit modification application was submitted
to NCDEQ on January 27, 2023.
Proposed Minor Permit Modification
Treated effluent produced by the Southeast Water Reclamation Facility (WRF) will normally be pumped
from the effluent pump station to the 26 new infiltration basins. However, a second set of pumps at the
effluent pump station are provided to pump treated effluent to the existing reclaimed water pump station at
the existing Summerhouse WWTP. This set of pumps includes two constant speed, submersible pumps
(one duty, one standby). The firm capacity of the transfer pumps is 350 gpm, which is 50 gpm below the
400 gpm capacity of the existing Summerhouse infiltration basin feed pump station. These pumps are not
part of this minor permit modification, but a part of the major permit modification already submitted.
The proposed project to be permitted under this minor modification to the Holly Ridge Non -Discharge
Permit is only for the 8-inch effluent transfer force main. Specifically, the minor permit modification is
for construction of approximately 7,400 Linear Feet (LF) of the 8-inch effluent return line to be installed
under Contract 1. The portion of the 8-inch line on the new Southeast WRF site will be installed under
Contract 2 and falls under the major modification non -discharge permit application.
There is no section of the 8-inch transfer pipe that is located within the 100-year floodplain. The new
Southeast WRF and its fence line are located on a 250-acre parcel owned by the Town of Holly Ridge and
leased under a long-term lease to ONWASA. The lease agreement is included in this permit application
under Section A Property Ownership Documentation. The existing Summerhouse WWTP is located on
a 5.52-acre parcel owned by ONWASA. The parcel report and deed for this property is also under Section
A A number of easements along Holly Ridge Road and Dolph Everett Road are required for the alignment
of the 8-inch transfer force main. ONWASA is currently negotiating these easements. The existing flow
meter at the reclaimed pump station will be used to track the flow volume and rate pumped from new
Southeast WRF to the Summerhouse infiltration basins (permitted under the Summerhouse Non -Discharge
Permit).
Per NCDEQ Non -Discharge Branch requirements, a Minor Permit Modification application to the existing
Holly Ridge permit (WQ0019907) is to be submitted separately from the Major Permit Modification
application. This is to allow construction of the treated effluent line. Operation of the treated effluent line
would be at a future date in a manner determined by NCDEQ and under the major permit modification.
This minor permit modification application includes only the drawings and specifications pertinent to the
ONWASA 2 of 3 Holly Ridge WWTP Non -Discharge

including controls for the 8-inch return line.
2. U.S. Army Corp of Engineers Individual permit 404 permit and 401 NCDEQ DWR permit which
covers all three contracts including the 8-inch pipe;
3. Fast Track permit for Contract 1.
The Fast Track permit application for Contract 1 was submitted January 31, 2023. The USACE permit is
being submitted at the same time as this permit application. The Erosion Control permit is scheduled to be
submitted in mid -February 2023. ONWASA/Wooten will keep the NCDEQ Non -Discharge Permitting
Branch apprised of the status of these other permits.

the "System"). The Authority may also abandon and dispose of any of the
Leased Assets which become obsolete or which the Authority otherwise deems

provided, however, that before disposing of any Leased Assets which the
Authority has abandoned it shall first give Notice of such intent to the Town. If
the Town does not take possession of such abandoned property within 45 days
of such Notice, the Authority shall be free to dispose of the property without
liability to the Town. Any portion of the Leased Assets comprised of real estate
or easements encumbering real estate not put to public use by the Authority for
a continuous period of eighteen months shall be considered abandoned and shall

regulations governing the use and operation of the System. The Authority shall
not permit the use of the System for any unlawful purpose.

Authority shall not incur current expenses in any fiscal year in excess of the
reasonable and necessary amount thereof. All revenues from the System shall
be the sole and exclusive property of the Authority and the Town shall have no
claim to such revenues by virtue of the Town owning the Leased Assets.
10. Annual Review of the Sim/Other Information and Reports. (a)
The Authority shall cause its consulting engineer to make a review of the System
at least once in each Fiscal Year and, on or before the 60th day next preceding

(a) its findings whether the System has been maintained in good repair, working
order and condition and (b) its recommendations as to:
(i) the proper maintenance, repair and operation of the System
during the ensuing Fiscal Year and an estimate of the amount of money
necessary for such purposes, and
(ii) the improvements, renewals and replacements that should
be made during the ensuing Fiscal Year and an estimate of the amount of money
necessary for such purposes.
Promptly after the receipt of such reports by the Authority, copies thereof

not been maintained in good repair, working order and condition, the Authority
promptly shall restore the System to good repair, working order and condition

after receipt of the Authority's annual audit provide a written report to the Town
on the financial condition of the Authority. The Executive Director shall also
provide such other written reports as the Town may reasonably request from time
to time so long as obtaining the information for the report does not require the
hiring of consultants or the expenditure of funds by the Authority other than the
normal salary of its staff and related costs.
11. Insurance. From the Commencement Date forward, the Authority
shall carry at all times insurance with a responsible insurance company or
companies, authorized and qualified under the laws of the State to assume the
risk thereof, covering such properties belonging to the System as are customarily

amounts equal to the greater of (1) the principal amount of all bonds of the
Authority at any time outstanding and (2) the full replacement cost of the
properties comprising the System, which amount shall be sufficient to ensue that
the Authority could not become a co-insurer under the terms and conditions of
the applicable policy or policies. The replacement cost of the properties
comprising the System shall be determined at least once every five years or
more often upon the request of the insurer by an appraisal by qualified
appraisers or other persons or entities selected by the Authority. The Authority

thereof.

reasonable terms and conditions, the insurance coverage required by this
paragraph may be modified in accordance with such determination, and the
coverage as modified shall constitute the minimum requirements of this
agreement.

involved, and (iii) prohibit cancellation or substantial modification by the insurer

cause there to be compliance with all applicable laws, orders, rules, regulations

paragraph shall prevent the Authority from contesting in good faith the
applicability or validity of any law, ordinance, order, rule, regulation or
requirement so long as the authority shall have received an opinion of Authority
counsel to the effect that such failure to comply during the period of such contest
will not materially impair the use or the revenue -producing capacity of the

a lien upon the System or System revenues if unpaid, provided that nothing
contained in this paragraph shall require the Authority to pay or cause to be
discharged, or make provision for the satisfaction and discharge of any cost,
expense, liability, or charge so long as the validity thereof shall be contested in
good faith and by appropriate legal proceedings in the same manner as is
hereinafter provided for the contest of liens and encumbrances.

System or System revenues or any part of the foregoing by reason of labor,
materials, supplies or other items supplied or claimed to have been supplied on

number of fill materials that have regional significance such as coral, slag,
cinders, crushed stone, and crushed shell. For these purposes of these
specifications, Class 1 materials shall be NCDOT #57 or #67 stone.
b. Class II: Coarse sands and gravels with maximum particle size of 44 mm
(1-1/2 in.), including various graded sands and gravels containing small
percentages of fines, generally granular and noncohesive, either wet or
dry. Soil Types GW, GP, SW, and SP are included in this class.
c. Class III: Fine sand and clayey gravels, including fine sands, sand -clay
mixtures, and gravel -clay mixtures. Soil Types GM, GC, SM, and SC are
included in this class.
d. Class IV: Silt, silty clays, and clays, including inorganic clays and silts of
medium to high plasticity and liquid limits. Soil Types MH, ML, CH and CL
are included in this class. These materials are not recommended for
bedding, haunching, or initial backfill.
e. Class V: This class includes the organic soils OL, OH, and PT as well as
soils containing frozen earth, debris, rock larger than 40 mm (1 1/2 in.) in
diameter, and other foreign materials. These materials are not
recommended for bedding, haunching, or initial backfill.
2. Backfill Zones: Each backfill zone shall extend the full width of the trench
bottom.
a. Foundation: Extending down from the bottom of bedding zone as defined
below.
b. Pipe Embedment
1) Bedding: Extending from 4 inches below the pipe bottom to the pipe
bottom for 30-inch diameter and smaller and 6 inches below the pipe
for pipes larger than 30 inches in diameter.
2) Haunching: Extending from the bedding (bottom of the pipe) to the
pipe spring line.
3) Initial Backfill: Extending from the haunching (pipe spring line) to 1 foot
above the top of the pipe.
c. Final Backfill: Extending from the initial backfill to the finish ground
elevation.
B. Laying Conditions:
1. Type 1: Flat bottom trench with loose backfill.
2. Type 2: Flat bottom trench with backfill lightly consolidated to centerline of pipe.
3. Type 3: Pipe bedded in 4 inches minimum of loose soil and backfill lightly
consolidated to top of pipe.

Forcemain Calculations

1.0 INTRODUCTION
The Engineering Calculations provided in this document accompany the submitted Holly Ridge
Minor Permit Modification. This document contains engineering calculations for the following as
part of transmission project (Contract 1):
• Treated Effluent Force Main from the new Southeast WRF to the existing Summerhouse
reclaimed pump station wet well.
2.0 CALCULATIONS
Treated effluent produced by the Southeast Water Reclamation Facility (WRF) will normally be
pumped from the effluent pump station to the 26 new infiltration basins. However, a second set
of pumps at the effluent pump station (i.e., the Transfer Pump Station) are provided to pump treated
effluent through an effluent return line to the existing reclaimed water pump station at the existing
Summerhouse WWTP. Calculations for transfer pump station are provided in the major permit
modification and not in this document. The firm capacity of these transfer pumps is 350 gpm,
which is below the capacity of the Summerhouse infiltration basin feed pump station. Thus, 350
gpm is the design flow in the treated effluent transfer forcemain.
Flow from the station will be transported through approximately 7,400 Linear Feet (LF) of the fl-
inch effluent transfer force main from the new Southeast WRF fence to the existing Summerhouse
reclaim water pump station wet well. From there, this water would be applied to the existing
Summerhouse infiltration basin via the existing Summerhouse WWTP reclaim water pump station.
Calculations for the transfer pump station are attached. These calculations were performed for the
major permit application, but do show and confirm that the scour velocity in the new transfer
forcemain (see Appendix A). Table 1 below provides the design criteria for the new treated
effluent transfer forcemain.

"on -discharge
Permitog Unit
AGREEMENT made this 1sr day of July, 2005, by and between ONSLOW WATER
AND SEWER AUTHORITY, a body politic and corporate of the State of North Carolina, and
the TOWN OF HOLLY RIDGE (the "Town") a political subdivision of the State of North
Carolina;
WITNESSETH:
WHEREAS, the County of Onslow (the "County % the City of Jacksonville
("Jacksonville"), and the Towns of Swansboro ("Swansboro' ), Richlands, North Topsail Beach
("North Topsail) and Holly Ridge ("Holly Ridge"), acting through their respective governing
bodies, pursuant to the provisions of Article 1, Chapter 162A of the General Statutes of North
Carolina, as amended, organized and incorporated the Onslow Water and Sewer Authority (the
"Authority") as a vehicle to assist in providing a satisfactory supply of potable water and sewer
collection/treatment for the member governments of the Authority; and
WHEREAS, the County, Jacksonville, Richlands, Swansboro, North Topsail and Holly
Ridge are the sole members of the Authority; and
WHEREAS, the Authority has entered into agreements with the United States of America
which provide that the Marine Corps Base, Camp Lejeune, shall provide specified volumes of
potable water and sewer treatment capacity to the Authority; and
WHEREAS, the Town is in need of additional potable water capacity and desires for the
Authority to make water from Camp Lejeune available to the Town's citizens; and
WHEREAS, the Town has determined that the Authority will be better able to meet the
needs of its citizens if the Authority leases and operates the water and sewer systems of its
member governments to which it will be providing water and sewer service (provided, however,
that said determination applies only to the Town of Holly Ridge's water system at the present
time), and
WHEREAS, the Authority is authorized and empowered to acquire, lease, construct,
reconstruct, extend, improve, maintain, better and operate potable water and sewage
collectiorVtreatment facilities and has determined that it will be in its best interest and in the best
interest of its member governments to lease, operate and maintain the water system of the Town;
and
WHEREAS, the Town has leased its water system to the Authority pursuant to a Capital
Lease Agreement (the "Lease") of even date with this Agreement, and
WHEREAS, in. consideration of the Town signing and delivering the Lease, the Authority
desires to enter into this Agreement to provide water service to the citizens of the Town.,

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and
conditions herein contained, it is agreed among the parties as follows:
1. Term. This Agreement shall become effective upon its execution and shall
continue in effect until the Lease is terminated.
2. Service. The Authority agrees, when economically and technically feasible, to
meet the potable water supply, treatment and distribution needs of the citizens of the Town, who
are not provided water, by any other governmental entity or public utility, subject to limitations
upon the Authority's ability to do so caused by (i) the amount of potable water supply, treatment
capacity and distribution lines available to the Authority, (ii) obligations of the Authority to
provide water service to others, (iii) the capacity of the Authority's water system and (iv)
completion of any improvements the Authority elects to make to enable it to provide water
service. Nothing herein shall obligate the Authority to provide any potable water supply if the
provision thereof will result in the Authority being in violation of any applicable laws or other
governmental regulations or result in a material breach of any agreements to which the Authority
is a party. The Authority shall maintain a satellite office in the Town for the purpose of bill
payment and telephone communication from customers. The Town shall if requested by the
Authority provide at actual cost an office at the town hall but not equipment (other than
telephones) and furnishings. The Authority shall pay the Town annually for the cost of such
office.
3. Planning. In order to provide for the public health and welfare, the Authority will
use reasonable efforts to develop additional potable water supply, treatment and distribution
facilities and sewer collection/treatment capacity to meet the needs of all of its customers and
will use financial planning practices, policies and procedures that are in the opinion of the
Authority reasonably sound to provide funds, through water and sewer user rates, impact fees
and related charges, and/or loans, necessary to provide the facilities to meet such needs.
4. Authorily to Provide All Water Service. So long as the Authority is capable of
meeting the water needs of the citizens of the Town pursuant to this agreement, the Town shall
not without the prior consent of the Authority acquire or produce potable water from any source
other than the Authority. The parties agree that in the event the Town breaches provisions of this
paragraph, monetary damages would not adequately compensate the Authority and in the event
of such breach, the Authority shall be entitled to equitable relief requiring that the Town comply
with the terms of this paragraph.
5. Operation and Maintenance. The Authority shall operate and maintain or cause

ONWASA Holly Ridge Wastewater System Improvements
Onslow Water & Sewer Authority, Onslow County NC
Endangered Species Biological Assessment -- 02 February 2023
Prepared for: The Wooten Company, Raleigh NC
Dim
MOGENSEN MITIGATION, INC
Mogensen Mitigation, Inc. (MMI) biologists conducted a biological assessment of potential impacts to federal
and state listed endangered and threatened animal and plant species that may occur in the vicinity of Holly
Ridge in Onslow County NC, in areas where the Onslow Water and Sewer Authority (ONWASA) is planning to
construct improvements to the local wastewater treatment system. A biological assessment is required for
federal and state permitting and public funding for the project.
Project Description
ONWASA operates a wastewater spray field facility on a 250 acre site owned by the Town of Holly Ridge (Parcel
# 4258001-08610) located at the north end of Dolph Everett Rd, approximately three miles ENE from downtown
Holly Ridge (Figures 1 and 2). ONWASA is planning to convert the spray fields to a wastewater infiltration basin
facility to meet the expected increased capacity need due to growth in the service area. The existing Holly Ridge
wastewater treatment plant (WWTP) on Jenkins Street will be decommissioned and replaced with a new pump
station, and new 12-inch and 16-inch force mains will be installed along existing utility corridors (2,100 feet) and
roadsides (11,800 feet) to convey the raw wastewater to a new 1.0 MGD WWTP to be built on the spray field
site.
Conversion of the wastewater spray irrigation facility to an infiltration facility will involve excavating a series of
26 basins, roughly one acre each, within the three existing spray fields (Figure 9). Each basin will be excavated 8
to 10 feet below the existing grade, and a 3 to 5-foot above ground berm erected around it. A network of 6 to fl-
inch diameter slotted drainage pipes will be installed in the surficial aquifer about 2 to 4 feet below the basin
bottoms, with a surface sand layer in each basin interior (Figure 10). Highly treated effluent from the new
WWTP will be applied to fill up the basins. The water will infiltrate into the basin sand layer, then flow to the
drainage pipes which will connect to ground water lowering submersible pump stations. These stations will
pump the groundwater into three constructed discharge swales (one discharge per field) with a terminal rip rap
apron to reduce discharge velocity and protect against soil erosion. The discharge water will then flow by a
combination of overland flow and infiltration into the adjacent forested areas and ultimately into the ditches
and stream flowing southward along the eastern side of the site to Kings Creek.
The WWTP effluent is currently treated to standards that meet groundwater quality regulations. The infiltration
basins will provide an additional final stage in the treatment process, promoting natural microbes in the sand
layer to further "polish" the effluent before discharge on land. The pumped groundwater discharge will meet
requirements under NC-DEQ Non -Discharge permitting rules. The current rules do not allow direct discharge of
the treated effluent into tidal waters in this area; thus, the infiltration basins are a necessary part of the effluent
treatment and disposal system for this project.

The infiltration basin drain system and groundwater pumping will lower the groundwater table in the area
around the basins. To avoid unintended groundwater withdrawal from the adjacent wetlands, the design
includes plastic barrier material along the outer edges of the drain trenches nearest to the wetland areas (Figure
10). The discharge of pumped groundwater will add water to the wetlands in the overland flow areas beyond
the riprap dissipators.
Environmental Setting & Habitat Impacts
The project area is in the Kings Creek watershed (Class SC-Sw-HQW) in USGS HUC # 03020302-0301 in the New
River basin. The only tidal waters near the project area is the lower segment of Kings Creek in the vicinity of
Holly Ridge Rd, 1200 feet west of the Summerhouse WWTP. The existing force main along this segment is sized
appropriately and no further improvements are needed in this area. All other waterways and wetlands in the
project area are non -tidal freshwaters and are not Areas of Environmental Concern (AEC) subject to Coastal Area
Management Act regulation.
Force Main Corridors
The force main corridors evaluated extend from the existing Holly Ridge WWTP at the north end of Jenkins
Street southeast along existing off -road utility corridors and then southwest along Homestead Lane and Stump
Sound Church Rd, and southeast along Morris Landing Rd to the intersection with Holly Ridge Rd where the new
line will connect to an existing 12-inch line running northeast along Holly Ridge Rd. From this intersection
eastward to the Summerhouse WWTP, the existing force main will convey the flows and no new pipe is needed.
A new pump station will also be built beside the Summerhouse WWTP, and a new 16-inch force main will be
installed east of Summerhouse along Holly Ridge Rd and then north along Dolph Everett Rd to the proposed
WWTP on the spray field site. Approximatley 2,100 feet of force main corridor is off -road along utility corridors
and 11,800 feet are along public road rights -of -way.
The off -road segment from the Holly Ridge WWTP to Homestead Lane crosses a small -stream swamp, a mesic
mixed pine -hardwood slope, and dry-mesic pine -oak woodland. The upslope areas adjacent to the corridor had
been recently clear-cut at the time of the field evaluation; aerial imagery shows it as predominantly pine forest
prior to clear -cutting. The swamp and floodplain immediately east of the WWTP including stream B and wetland
DE (Figure 5C) were densely forested. Wetland FIG is in a slight depression (possibly an old road bed?) half way
up the slope. The proposed force main segment crossing these two wetlands and one stream will be installed by
horizontal directional drilling (HDD) beginning and ending in uplands, to avoid disturbance in these habitats.
Upslope of wetland FG, the pipe will be installed by open -trenching in a 30 to 40 ft wide temporary construction
corridor.
The roadside force main segments from Homestead Lane to Holly Ridge Rd are bordered by a mix of residential
land and mixed pine and hardwood forest. Four headwater seep wetlands are located along the south side of
Morris Landing Rd but do not extend beyond the roadside ditch along the north side where the force main will
be installed (Figures 5D and 5E). The force main along these roads will be installed by open -trenching in a
temporary construction corridor extending 20 to 30 ft beyond the edge of pavement.
The roadside force main segments from the Summerhouse WWTP to Dolph Everett Rd are bordered by a mix of
residential and agricultural land, recreational land (Summerhouse Golf course), NC-WRC game lands, and mixed
pine and hardwood forest. A small stream swamp and perennial tributary to Kings Creek (K1) crosses Dolph
Everett Rd approximately 850 feet north of Holly Ridge Rd (Figure 5F). The force main crossing this stream and
wetland will be installed by HDD beginning and ending in uplands, to avoid disturbance in these habitats. Other
force main segments along these roads will be installed by open -trenching in a temporary construction corridor

extending 20 to 30 ft beyond the edge of pavement. The raw wastewater line flowing north and a reuse line
flowing south will be installed along the east side of Dolph Everett Rd, and a potable water line to supply the
new WWTP will be installed along the west side of Dolph Everett Rd.
The intermittent stream (K2) that crosses the existing gravel access road at the southwest corner of the spray
field site and its adjacent wetland RA is the only area where open -trench force main installation will affect
streams or wetlands (Figure 5H).
Spray Field Site (Infiltration Basins and WWTP)
Elevations on the spray field site range from 20 feet above NAVD in the Kings Creek tributary along the southern
edge of the site to 45 feet on the northwest portion. USDA soil mapping on the site indicates Goldsboro,
Baymeade, and Pactolus series soils on the drier areas, Leon and Torhunta series soils on wetter flats, and
Muckalee loam along the small stream corridors on the northwest and southwest portions of the site (Figures 2
and 3).
The property was mostly ditched and bedded for pine plantation use prior to 1980, and the streams along the
eastern and southern sides of the site were channelized and partially straightened (Figure 6). Drainage ditches
and silvicultural bedding ridges and swales are visible across most of the site in aerial images from the 1980s to
2003. The three existing spray fields, wastewater holding pond, roads, and related facilities were built in 2004
to 2005 and occupy approximately 115 acres of former pine plantation areas (Figure 5). The least disturbed
habitat on the site is a 5-acre area of swamp and adjacent forested slopes near the northwest corner of the site,
which includes approximately 1,000 feet of a small headwater swamp stream. The remaining 130 acres contains
second -growth mixed pine and hardwood forest with a dense understory shrubs and vines including Ilex,
Morella, Vaccinium, Persea, Symplocos, Lyonia, Smilax, Vitis, Gelsemium, and other plants characteristic of pine
flatwoods and pocosin communities. A majority of the remaining forested area appears to be wetlands, despite
the many drainage ditches that have probably lowered the water table.
Adjacent lands to the west, north, and east are mostly wooded, including the Folkstone Savanna Conservation
Area managed by the NC Wildlife Resources Commission (WRC). Adjacent lands to the south include a mix of
wooded, agricultural, and rural residential lands, including the Stones Creek Game Lands and dove hunting
fields, also managed by WRC (Figure 8).
Most of the proposed land disturbance on the spray field property for the new WWTP and infliltration basins
will be within the existing spray fields, which contain managed grasses and various native and non-native weeds
typical of agricultural fields. There are four areas with natural scrub and woody vegetation that will be
disturbed:
1) a 2.0 acre wooded wetland/upland patch in the middle of spray field #1 (Figures 5G and 9A)
2) a 0.5 acre wooded upland area on the east side of spray field #1 (Figures 5G and 9A)
3) 850 ft of access road for upstream water sampling on the northeast side of spray field #1 (Figure 9A)
4) 150 ft of access road for downstream water sampling on the southeast side of spray field #2 (Figure 913)
The 2.0 acre isolated forest patch in spray field #1 (34.5145,-77.5017) has a canopy of 20 to 30 year old planted
loblolly and longleaf pines, and understory of mixed hardwoods, shrubs, and vines. A ditch excavated between
1999 and 2002 runs through a wetland in the middle, draining northward offsite into another ditch.
Approximately half of this forest patch area is wetland. A depression at the upper (south) end of this area -
possibly a limesink depression - has an open understory including Nyssa, Cyrilla, Ilex, and Lyonia, and sparse
groundcover including Juncus, Ludwigia, and mosses. No standing water was present during the field study in
December 2021, but swollen bases on the older trees suggest that the depression formerly held ponded water

and may still during wet weather. Beyond the central wet depression and ditch, the remaining area is dense
shrub and sapling forest.
The 0.5 acre affected area to the east of spray field #1 (34.5148,-77.4988) is an upland ridge that appears to
have been a staging area for timber harvesting and silvicultural bedding operations in the 1980s, and possibly
also for hunting access. Planted loblolly pines in this area are smaller and less dense than in the adjacent lower
and wetter areas to the north and south. The understory is shrub and sapling -dominated, including
Liquidambar, Nyssa, Acer, Quercus, Ilex, Vaccinium, Cyrilla, Lyonia, Morella, Persea. Predominant groundcover
plants are Vaccinium, Lyonia, Andropogon, Arundinaria, Gelsemium, Smilax, Vitis, and Campsis.
The two water sampling access road corridors traverse former pine plantation land that has been naturalizing
back to a pine flatwoods/pocosin community for about 20 years. Vegetation is similar to that described above
on the 0.5 acre upland ridge, but with denser thickets of Smilax, Vitis, Campsis and other vines.

Federal Species Accounts and Likelihood of Impacts
Species descriptions and habitat requirements were compiled from US Fish and Wildlife Service (FWS), NC
Natural Heritage Program (NHP), NC Wildlife Resources Commission (WRC), and other published and online
sources. Previously reported locations within several miles of the project area were obtained from the NHP
Data Explorer and NC Wildlife Resources Commission. Characteristics for identifying potentially suitable habitats
for each species are described in the species accounts below.
Northern Long-eared Bat (Myotis septentrionalis) -- Endangered
Northern long-eared bats roost in colonies in caves and mines in western NC during winter. Bat hibernacula
caves have relatively stable temperatures, high humidity, and minimal air currents. In spring, the bats leave their
hibernacula and migrate across much of NC to their summer foraging areas, usually with a mix of forested and
open habitat, where they feed on flying insects over fields, rivers, and other open habitats. During the warm
seasons these bats roost singly or in small colonies in cavities or crevices of live or dead trees, beneath loose
bark, or in buildings. Maternity roost sites, often in hollow trees or rock crevices, are occupied during the pup
rearing season from June through July. The NC Natural Heritage Program (NHP) has only one recent record of
Northern long-eared bat in Onlsow County, in summer along the White Oak River more than 20 miles from the
project area.
There is no known winter hibernaculum for Northern long-eared bats in Onslow County or elsewhere in eastern
NC; these bats may occur near the project area during spring to early fall, and may roost in trees on the site.
The project will require removing potentially suitable roosting trees (mostly Pinus, Nyssa, Acer, and
Liquidambar) from 2.5 acres on the spray field site and up to 1.3 acres in narrow strips along the roadside force
main corridors. The other 128 acres of forest habitat on the spray field site will remain undisturbed. If
necessary, tree removal can be conducted during November to March when Northern long-eared bats are
unlikely to be in the area. Based on this analysis, the project may affect but is not likely to adversely affect the
Northern long-eared bat.
Tricolored Bat (Perimyotis subflavus) -- Proposed Endangered
Tricolored bats roost in colonies during winter in caves, mines, and rock crevices in western NC, and in road
culverts and similar cave -like features in eastern NC. Compared with the Northern long-eared bat, Tricolored
bats have a less distinct hibernation period and may emerge to forage during warm periods in winter. During

the warm seasons, these bats migrate across much of NC to forage in both forested and open habitats, where
they feed on flying insects over fields, rivers, and other open habitats. They roost singly or in small colonies in
cavities or crevices of live or dead trees, beneath loose bark, under bridges and culverts, or in buildings.
Maternity roost sites are occupied during the pup rearing season from June through July. NHP has recent
records of Tricolored bats at Camp Lejeune and Holly Shelter Game Lands; both sites are at least 10 miles from
the project area.
Tricolored bats may occur near the project area year-round, and may roost in trees or culverts on the site. The
project will
require removing potentially suitable roosting trees (mostly Pinus, Nyssa, Acer, and Liquidambar) from 2.5 acres
on the spray field site and up to 1.3 acres in narrow strips along the roadside force main corridors. The other 128
acres of forest habitat on the spray field site will remain undisturbed. If necessary, tree removal can be
conducted during November to March when Tricolored bats are unlikely to be using trees as roost sites. Based
on this analysis, the project may affect but is not likely to adversely affect the Tricolored Bat.
Red -cockaded Woodpecker (Picoides borealis) -- Endangered
The Red -cockaded woodpecker (RCW) occurs in large areas of mature pine -dominated forest, typically 80 to 100
acres or more. Unlike other woodpeckers, they excavate cavities for nesting and roosting exclusively in live
pines, typically 80 years or older and surrounded by an open understory with minimal hardwood encroachment
or climbing vines. They live in small groups comprising a breeding pair and one to three "helpers" that are often
the pair's offspring from previous years. Foraging habitat comprises pine -dominated stands at least 10-inch
diameter (generally 30 years or older) with sparse understory and within 0.5 mile from the cavity trees. Camp
Lejeune Marine Corps Base has been managing land for RCW since the 1980s and now has many RCW breeding
groups in areas east and west of the New River. Other active groups are known in Pender County west of Holly
Ridge. The nearest known active group is about 6 miles from the project area. Two historical RCW sites are
known in the Sneads Ferry area, 3 to 5 miles east of the project area; both sites have been inactive since 1980 or
earlier.
There is no suitable RCW nesting habitat on the project site. Pines in areas with open understory are too young
and small to be suitable for cavities, and the older, larger pines occur only in areas with dense sub -canopy and
understory trees and shrubs. Pine stands 30 years or older on the spray field site and along the force main
corridors may now be suitable as foraging habitat for RCW groups nesting off -site, but there is no known active
group within several miles from the project area. Based on this analysis, the project is not likely to affect the
Red -cockaded woodpecker.
Pondberry (Lindera melissifolia) -- Endangered
Pondberry is similar to the widespread Common spicebush but has far more restrictive habitat requirements,
being limited to shallow seasonal pools and wet depressions in four NC counties. Suitable habitat may be in
clay -based Carolina bays or similar wet depressions, generally associated with pine flatwoods and pocosin shrub
communities. Like Roughleaf loosestrife and Cooley's meadowrue, this shrub relies on periodic fire to limit the
growth of trees and taller shrubs and maintain sufficient sun exposure for survival. NHP has two known sites
that support Pondberry in Onslow County, both on Camp Lejeune property. The nearest is approximately four
miles north of the project area.
ranwww.Mogmit.com Page 16
MOGENSEN MITIGATION. INC

MOGENSEN MITIGATION INC.
The wet depression in the isolated forest patch in spray field #1 might have been suitable habitat for Pondberry
prior to 1980, but drainage ditching, forestry bedding, and fire suppression over the past 40+ years have
rendered it unsuitable at present. The remaining areas that will be affected by the project are previously
cleared fields, non -wetland forests, and dense scrubby forests which are not suitable habitats. Based on this
analysis, the project is not likely to affect the Pondberry.
Roughleaf loosestrife (Lysimachia asperulifolia) -- Endangered
Roughleaf loosestrife occurs in wet pine savannas and open edges of pocosins and wet pine flatwoods where
periodic fires every few years to prevent shrubs and trees from overshadowing them. In areas without periodic
fires, remaining populations often persist along roadsides and utility rights -of -way where occasional mowing
limits the growth of trees and shrubs. There are several recent records of Roughleaf loosestrife on Camp
Lejeune property north of the project site and on Holly Shelter Game Lands in Pender County to the west; the
nearest known site is on Camp Lejeune 1.5 mile from the project site.
The wet depression in the isolated forest patch in spray field #1 might have been suitable habitat for Roughleaf
loosestrife prior to 1980, but drainage ditching, forestry bedding, and fire suppression over the past 40+ years
have rendered it unsuitable at present. The wetland edges where Roughleaf loosestrife could have occurred is
now dominated by dense shrubs and vines. The remaining areas that will be affected by the project are
previously cleared fields, non -wetland forests, and dense scrubby forests which are not suitable habitats. No
suitable habitat was observed along the force main corridors. Based on this analysis, the project is not likely to
affect Roughleaf loosestrife.
Cooley's meadowrue (Thalictrum cooleyi) -- Endangered
Cooley's meadowrue occurs in wet pine savannas and open edges of pocosins and wet pine flatwoods with high
pH soils (near neutral) derived from marl (limestone), which is a rare habitat in the NC Coastal Plain. Like
Roughleaf loosestrife and Pondberry, it requires periodic fires to prevent overgrowth of shrubs and trees. In
areas without periodic fires, remaining populations often persist along roadsides and utility rights -of -way where
occasional mowing limits woody competition. Nearly all of the known records for Cooley's meadowrue in NC
are in a small area in western Onslow County and eastern Pender County where the Castle Hayne Formation
limestone occurs at shallow depths; the nearest site is 9 miles from the project area.
Wetland habitats on the project site appear to have acidic soils that are not suitable for Cooley's meadowrue;
we did not observe any characteristic calciphile plant species. Habitats beyond the mowed spray fields also have
excessively dense woody vegetation due to past land management and fire suppression. The remaining areas
that will be affected by the project are previously cleared fields, non -wetland forests, and dense scrubby forests
which are not suitable habitats. No suitable habitat was observed along the force main corridors. Based on this
analysis, the project is not likely to affect Cooley's meadowrue.
Black Rail (Laterallus jamaicensis) -- Threatened
The Black rail forages and nests in brackish marshes and the lower portions of tidal freshwater marshes. It does
not inhabit forests or dense shrub -dominated habitats. The nearest suitable marsh habitat for the Black Rail is in
the tidal portion of Kings Creek 0.2 mile southwest of the Summerhouse WWTP. There is no NHP records of
Black Rail within several miles, and the project will not affect the Kings Creek marshes. The advanced

wastewater treatment method and land disposal should protect water quality in Kings Creek. Based on the lack
of suitable habitat, the project is not likely to affect the Black Rail.
American Alligator (Alligator mississippiensis) -- Threatened by Similarity of Appearance
The American Alligator is not a federally endangered or threatened species, but is listed as Threatened by
Similarity of Appearance (TSA) to protect the American Crocodile from hunting and trade. However, the
Alligator is listed as threatened under state law. Alligators occur in coastal plain rivers, lakes, and swamps and
marshes adjacent to open water bodies, from fresh to slightly brackish. They do not normally inhabit forests or
dense shrub -dominated habitats along small headwater streams. The nearest suitable habitat for Alligators is in
the tidal portion of Kings Creek 0.2 mile southwest of the Summerhouse WWTP. NHP has recent records of
Alligators in Kings Creek south of Holly Ridge Rd, but no project impacts are planned in that area. Based on this
analysis, the project is not likely to affect the American Alligator.
Atlantic Sturgeon (Acipenser oxyrinchus) -- Endangered
West Indian Manatee (Trichechus manatus) -- Threatened
The Atlantic Sturgeon and West Indian Manatee occur in coastal ocean waters, estuaries, and rivers. Most of
their time is spent in tidal areas, but sturgeon adults migrate far upstream into freshwater rivers to spawn.
Neither sturgeon nor manatees inhabit small headwater streams. The nearest suitable habitat for Atlantic
Sturgeon and West Indian Manatee is in the tidal portion of Kings Creek 0.2 mile southwest of the Summerhouse
WWTP. NHP has recent records of Atlantic Sturgeon in Everett Bay and Topsail Sound near the mouth of Kings
Creek, and Manatee records near the mouth of New River several miles farther east. The advanced wastewater
treatment method and land disposal should protect water quality in Kings Creek. Based on this analysis, the
project may affect but is not likely to adversely affect the Atlantic Sturgeon and West Indian Manatee.
Piping Plover (Charadrius melodus) -- Threatened
Red Knot (Calidris canutus rufa) -- Threatened
Seabeach Amaranth (Amaranthus pumilus) -- Threatened
These three species (two shore birds and one plant) occur on ocean beaches and island end flats -- habitats that
do not occur in the project vicinity. The nearest suitable beach habitat for any of these species is approximately
three miles from the project area. NHP has recent records of Seabeach Amaranth from several locations along
Topsail Island beaches, and records for the two birds toward the ends of the island 5 to 10 miles away. Based
on this analysis, the project is not likely to affect the Piping Plover, Red Knot, or Seabeach Amaranth.
Green sea turtle (Chelonia mydas) -- Threatened
Kemp's Ridley sea turtle (Lepidochelys kempii) -- Endangered
Leatherback sea turtle (Dermochelys coriacea) -- Endangered
Loggerhead sea turtle (Caretta caretta) -- Threatened
These four sea turtle species occur in the ocean, sounds, and brackish reaches of rivers, and nest exclusively on
ocean beaches. The nearest suitable beach nesting habitat for these species is approximately three miles from
the project area, and three of these species have site records in the estuarine waters near New River Inlet.
Based on this analysis, the project is not likely to affect the Green sea turtle, Kemp's Ridley sea turtle,
Leatherback sea turtle, or Loggerhead sea turtle.

State -Listed Endangered & Threatened Species
The NC Natural Heritage Program (NHP) database was queried for records of rare animal and plant species listed
as endangered, threatened, or special concern by the NC Wildlife Resources Commission (WRC) and/or the NC

Branched Gerardia (Agalinis virgata) -- Threatened
The Venus Flytrap occurs in wet pine savannas, seeps, and open edges of pocosins and wet pine flatwoods
where low nutrient levels and periodic fires every few years prevent trees, shrubs and dense herbs from
overshadowing them. In areas without periodic fires, remaining populations often persist along roadsides and
utility rights -of -way where occasional mowing limits the growth of competing plant species. There are several
recent nearby records of Venus Flytrap in the Stones Creek Game Lands / Folkstone Savannas property.
The wet depression in the isolated forest patch in spray field #1 might have been suitable habitat for the Venus
Flytrap prior to 1980, but drainage ditching, forestry bedding, and fire suppression over the past 40+ years have
rendered it unsuitable at present. The wetland edges where Venus Flytraps could have occurred is now
dominated by dense shrubs and vines. MMI searched for Venus Flytraps in this area and along field edges

throughout the project site in December 2021 and did not find any. December is not the optimal season to
search for this plant, but it is usually detectable at least until the first hard freeze, which had not yet occurred.
The other areas that will be affected by the project are previously cleared fields, non -wetland forests, and dense
scrubby forest that are not suitable habitats.
The infiltration basins in the northern field are on the opposite side of Kings Creek from the Venus Flytrap sites
on the adjacent property; the project is therefore not likely to affect groundwater levels or nutrient
concentrations in the vicinity of those populations. Furthermore, the infiltration basins in the northern field will
drain eastward, away from the Folkstone Savannas preserve area. Based on this analysis, the project is not
likely to affect the Venus Flytrap.
Savanna Milkweed (Asclepias pedicellata) -- Special Concern
The Savanna Milkweed occurs in the drier portions of longleaf pine savannas and open edges in mesic pine
flatwoods where periodic fires every few years to prevent shrubs and trees from overshadowing them. In areas
without periodic fires, remaining populations often persist along roadsides and utility rights -of -way where
occasional mowing limits the growth of trees and shrubs. There are recent records of Savanna Milkweed on
Camp Lejeune property within one mile from the project site.
Portions of the site might have been suitable habitat for the Savanna Milkweed prior to 1980, but drainage
ditching, forestry bedding, and fire suppression over the past 40+ years have rendered most of the site
unsuitable or marginally suitable at present. The 0.5 acre upland forest area east of spray field #1 may have
sufficiently open canopy to support this plant, but the substantial soil disturbance and use as pine plantation
makes it unlikely that Savanna Milkweed could persist in this area. No suitable -looking habitat was observed
along the force main corridors. This plant would not have been identifiable during the December field study; a
presence or absence determination is therefore inconclusive. However, based on small area of impact and low
quality of habitat, the project may affect but is not likely to adversely affect the Savanna Milkweed.
Leconte's Flatsedge (Cyperus lecontei) -- Threatened
Brown Bogbutton (Lachnocaulon minus) -- Threatened
Leconte's Flatsedge and Brown Bogbutton grow along moist to wet edges of limesink pools and other wet
depressions in pine savannas and thin -canopy areas of pine flatwoods where woody vegetation is limited by
fires. In disturbed habitats they may persist along roadside drainage ditches and utility easements where
periodic mowing reduces competition from taller plants. NHP has recent records of Leconte's Flatsedge and
Brown Bogbutton on Camp Lejeune property near US-17 one to two miles from the project site.
The wet depression in the isolated forest patch in spray field #1 might have been suitable habitat for Leconte's
Flatsedge and Brown Bogbutton prior to 1980, but drainage ditching, forestry bedding, and fire suppression over
the past 40+ years have rendered it unsuitable or marginally suitable at present. The wetland edges are now
dominated by dense shrubs and vines. These species would not have been identifiable during the December
field study; a presence or absence determination is therefore inconclusive. The other areas that will be affected
by the project are previously cleared fields, non -wetland forests; and dense scrubby forests which are not
suitable habitats. No suitable -looking habitat was observed along the force main corridors. Based on small area
of impact and low quality of habitat, the project may affect but is not likely to adversely affect the Leconte's
Flatsedge and Brown Bogbutton.

Coastal Plain St. John's -wort (Hypericum brachyphyllum) -- Special Concern
Hooker's Milkwort (Polygala hookeri) -- Special Concern
Hooker's Milkwort and Coastal Plain St. John's -wort grow almost exclusively in pine savannas with regular fires
every few years to reduce competing woody vegetation. Unlike many other milkworts and St. John's -wort
species, these plants seldom occur in ditches and disturbed sites. NHP has recent records of Hooker's Milkwort
and Coastal Plain St. John's -wort on Camp Lejeune property near US-17 about one mile from the project site.
Portions of the site might have been suitable habitat for Hooker's Milkwort and Coastal Plain St. John's -wort
prior to 1980, but drainage ditching, forestry bedding, and fire suppression over the past 40+ years have
rendered most of the site unsuitable or marginally suitable at present. The 0.5 acre upland forest area east of
spray field #1 may have sufficiently open canopy to support this plant, but the substantial soil disturbance and
use as pine plantation makes it unlikely that these two plants could persist in this area. These species would not
have been identifiable during the December field study; a presence or absence determination is therefore
inconclusive. However, based on small area of impact and low quality of habitat, the project may affect but is
not likely to adversely affect Hooker's Milkwort and Coastal Plain St. John's -wort.
Eastern Diamondback Rattlesnake (Crotalus adamanteus) -- Endangered
Carolina Pigmy Rattlesnake (Sistrurus miliarius) -- Special Concern
Mimic Glass Lizard (Ophisaurus mimicus) -- Endangered
The Eastern Diamondback Rattlesnake, Carolina Pigmy Rattlesnake, and Mimic Glass Lizard all occur in pine
flatwoods, savannas, and pine -oak sandhill woodlands with open areas for sunning and deep holes from
decayed tree stumps for use in winter and hot summer days. NHP records of these three species in the project
vicinity are historical, from the 1940s to 1970s, including a Mimic Glass Lizard record from 1975 on Morris
Landing Rd in the project area.
These three reptiles are cryptic species, and populations could still occur in the project vicinity despite the lack
of recent records. However, forestry bedding (including stump removal) and fire suppression over the past 40+
years has certainly degraded the habitat quality for these species across most of the project site. Patches of
pine -oak woodlands along Homestead Lane and the off -road powerline corridor NE of Homestead Lane, and
along Stump Sound Church Rd and Morris Landing Rd may be suitable. Based on the relatively small area of
impact and low quality of remaining habitat, the project may affect but is not likely to adversely affect the
Eastern Diamondback Rattlesnake, Carolina Pigmy Rattlesnake, and Mimic Glass Lizard.
Carolina Swamp Snake (Seminatrix pygaea) -- Special Concern
The Carolina Swamp Snake lives in dense aquatic and emergent plant beds in cypress -gum swamps, ponds, slow -
flowing streams, and wide segments of ditches, where it feed on worms, small fish and amphibians. NHP
records of this small snake in the project vicinity are historical, from the 1940s. The small channelized streams
and ditches on the project site are shaded by dense trees and shrubs, and lack the aquatic and emergent plant
beds that Carolina Swamp Snakes prefers. There is no suitable habitat for this species on the spray field site.
The larger streams along the force main corridors on Dolph Everett Rd and east of the Holly Ridge WWTP might
be suitable, but HDD installation will avoid impacts at these sites, Therefore, the project is not likely to affect
the Carolina Swamp Snake.
