Re: Response to Additional Information Request
Holly Ridge WWTF Minor Modification to Non -Discharge Permit No. WQ0019907
Onslow Water and Sewer Authority (ONWASA)
Dear Mr. Saunders:
We received your request for additional information (dated June 6, 2024) on the Minor Modification
application to the Non -Discharge Permit for the Holly Ridge Wastewater Treatment Facility (WQ0019907),
which we submitted on April 1, 2024, for SE Area WW Capacity Improvements, Contract 1 — Transmission
System (SRP-W-ARP-0189). Please find attached the following:
• Signature Authority Designation (NDSDAL) Letter.
• Updated WWIS 06-16 Form.
• Updated Engineering Plans showing the 8-inch treated effluent force main.
• Relevant Specifications for the 8-inch treated effluent force main.
Responses to your additional information request are provided below:
A. Overall:
1. The 8-inch effluent force main on parcel 747-13.75 containing the storage lagoon and spray fields
that are associated with this permit shall be permitted in this application rather than the
Summerhouse WWTP (Permit No. WQ0029945) because this modification is adding flow and a
new source to this facility. A response to this item is not needed.
Noted.
2. Upon reviewing monitoring reports for this facility, it was noted that the Holly Ridge WWTF had
an average daily flow (ADF) of 214,876 gallons per day (GPD) in 2023, which exceed 90% of the
224,673 GPD permitted capacity for the disposal system. As this application is adding a new source
to this facility, the Permittee shall provide a demonstration that this modification does not violate
15A NCAC 02T .0118.
Technically, we are adding a new source of effluent flow to the sprayfields from the Summerhouse
WRF. However, the combined effluent flow from the Holly Ridge and Summerhouse collection
systems is not necessarily being increased. The strategy is that ONWASA will continue to manage
treatment of total combined collection system wastewater currently generated by splitting some
flow from the Holly Ridge system to the Summerhouse WRF. Treated effluent flow will continue
to be managed to keep flow to the sprayfields within permitted values. Once the force main to the
North Topsail WWTP is completed, the Holly Ridge WWTF will be shut down and wastewater
from the service areas will be split between the Summerhouse WRF and the North Topsail WWTP.
TheWootenCompany.Com, DESIGNING THE FUTURE ►

Page 2 of 4
At that time, there will be only one flow source to the sprayfields: the 8-inch treated effluent line
from the Summerhouse WRF, and the flows to the fields will be managed to permit values. In the
interim period, ONWASA can actively manage flows to the Holly Ridge sprayfields and
Summerhouse infiltration beds to be at or below the permitted capacity, as they already do now.

County Water and Sewer Authority (ONWASA).
B. Contractor shall coordinate for telemetry/SCADA, forcemain tie-ins and pump
station commissioning with the following Contractors for the following projects which
are expected to be occurring concurrent with this project:
1. Upgrade of the existing Summerhouse Wastewater Treatment Plant (WWTP) at
the Summerhouse Pump Station site. ONWASA is currently upgrading existing
process units, adding new screens, membrane units, UV disinfection, and
SCADA system controls. Telemetry for Contract 1 will need to be coordinated
with the SCADA system installed in the Summerhouse WWTP upgrade project.
This project is currently under construction and is scheduled to be completed in
October/November 2024.
2. Southeast Area Wastewater Capacity Improvements: Contract 2 Transmission
System. This project will be for the installation of a new 18-inch diameter raw
wastewater force main from the termination of the 18-inch force main on this
Contract 1 to the North Topsail Wastewater Treatment Plant (WWTP) influent
diversion box. The length of this force main is approximately 6.5 miles. This
project is currently under design and is anticipated to start construction in
April/May of 2025. This force main must be completed in order to put the new
Summerhouse and Holly Ridge Pump Stations in full operation.
3. A third contract for construction of a new screen and grit headworks at the
diversion box area at the North Topsail WWTP is also planned. However, this
may affect Contract 2 above but should not affect Contract 1 work.
1.02 CONTRACTS
A. Project construction will be let under one Contract with construction including, but
not limited to, the following major work items:
1. Construction of a new Holly Ridge Pump Station at the existing Holly Ridge
Wastewater Treatment Plant (WWTP) site. New pump station to include

seepage with slope drains.
H. Water from dewatering operations must be disposed of in accordance with the North
Carolina Sedimentation Pollution Control Act.
3.05 USE OF EXPLOSIVES
A. Explosives may not be used on the Project.
3.06 TOPSOIL
A. A thin veneer of topsoil was encountered at the each pump station site. Strip topsoil
from areas to be disturbed such that the underlying "clean" soils remain intact and

the site, the ground surface is not expected to support rubber -tired construction
equipment. It is anticipated that loose near -surface soils (estimated to be 3 to 4 feet
in depth) will require undercut and replacement in the footprints of all structures and
pavements at the site, plus 5 feet outside. The undercut excavations will require
dewatering as recommended in Paragraph 3.04 of this section. The undercut
bottoms shall be observed by the Engineer to determine if sufficient undercut has
occurred prior to fill placement. Payment for in place repair or undercutting and
backfilling of unsuitable areas shall be as indicated in the Measurement and
Payment paragraph.
B. Perform undercutting of unsuitable soils with tracked excavators, top loading dump
trucks or similar equipment approved for the use by the Engineer. Backfill undercut

and cross sections indicated on the Drawings and be uniformly sloped for a positive
drainage away from structures.
F. Excavate rock encountered in cut sections to a depth of 6 inches below finished
subgrade and backfill with satisfactory material.
G. Scarify the existing subgrade surface to a minimum depth of 6 inches and
recompact if subgrade density is less than the degree of compaction for the
proposed fill material. Plow or bench existing ground surfaces steeper than one
vertical to four horizontal in such a manner that the fill material will bond with or be
keyed to the existing surface. Use compaction equipment suitable for the soil being
compacted. Moisten or aerate material as necessary to obtain the optimum moisture
content within plus or minus one percent to obtain specified compaction.
H. Approved compacted subgrade that is disturbed by construction or adverse weather
shall be scarified and re -compacted as specified previously. Re -compaction over
utilities shall be by hand tamping.

include silty and clayey sands and low to high plasticity clays with SPT resistances
SE Area Capacity Improvements Earthwork - 02300-6
Contract 1 - Transmission

between 0 and 21 bpf. The silty and clayey sands and low plasticity soils may be
used as backfill provided compaction moisture is maintained near optimum during
placement. The moisture levels of these soils are expected to be well above
compactable levels (especially those soils below the water table) and drying of
these soils will be required prior to placement and compaction. Use of lime may be
required if natural drying is not effective.
B. Offsite borrow should consist of sandy soils having Unified soil classifications of SW,
SM, SC, and SP. SW and SP soils are preferable as the initial fill lift in undercut
bottoms. These soils shall have standard Proctor maximum dry unit weights of at

complete prior to construction of settlement -sensitive structures. All site grading
shall be completed prior to any structure construction.
D. Place and compact fill and backfill material adjacent to structures in a manner that
prevents wedging and eccentric loading on or against structures. Do not use
equipment adjacent to structures that may overload structure. Backfill against
structure only after concrete has attained the specified 28-day compressive
strength. It is recommended that no self-propelled compaction equipment be used
within 5 feet of structure walls.
E. Stone Base: Structures shall have a compacted crushed stone subgrade to the
depth of 12 inches with a nonwoven geotextile placed below the bottom of the stone
layer.
F. All structural fill shall be placed in 8 to 10-inch loose lifts (6 to 8 inches for utility
trench backfill) and compacted to at least 95 percent of the standard Proctor
maximum dry density (MDD) (ASTM D 698). The moisture content of structural fill
shall be maintained within +/- 3% of optimum moisture during compaction. The top
12 inches beneath pavements and structures shall be compacted to at least
G. Place backfill and fill material in accordance with the following:
1. Maximum uniform loose lifts: 8-10 inches (6-8 inches for utility trench
backfill)
