RE: CAMA Major Permit Application for Brunswick H2GO WTP Effluent Discharge at Belville, NC.
Dear Ms. Coats,
Attached is a CAMA Major Permit application and supporting documents for a proposed effluent
discharge pipeline extending from the proposed Brunswick Regional Water and Sewer H2GO water
treatment plant (WTP) on Gregory Rd in Belville to the proposed effluent diffuser in the Brunswick
River, adjacent to Brunswick H2GO's existing wastewater effluent discharge.
The project components addressed in this CAMA Major Permit application include: 1)
approximately 17,450 feet of buried effluent discharge line from the proposed WTP eastward to
the diffuser in the Brunswick River; 2) The total length includes 400 ft of buried effluent discharge
line from the river bank eastward to the diffuser structure; 3) a 35 -ft long diffuser pipe on the river
bed with four discharge ports extending one foot above the river bottom; and 4) a row of pilings to
mark the diffuser location and to support a debris deflector.
We have completed the relevant portions of CAMA forms MP -1, MP -3, and MP -4, as instructed by
you and Debra Wilson, along with supporting text, plans, and maps. A CAMA Major Permit
application fee of $400 payable to NC Department of Environmental Quality is also included.
The proposed WTP will produce potable water for the H2GO service area (Leland, Belville,
Navassa, and adjacent areas) from brackish groundwater aquifers that are not currently tapped for
any other uses. H2GO will no longer routinely use Brunswick County for water supply; this will
free up approximately 2 MGD (current daily demand) of Brunswick County water for other
customers. At full design capacity of 4.0 million gallon per day (MGD), the WTP will require about
5.0 MGD of raw groundwater and will discharge about 1.0 MGD of reverse osmosis (RO
concentrate effluent with a salinity and major ion composition similar to seawater., hTC,

River will ensure rapid mixing of the effluent, more than 40x dilution within 10 meters from the
diffuser ports. The eastern half of the WTP effluent line will share the existing right-of-
way/easement to the riverbank with H2GO's Belville wastewater treatment plant (WWTP) effluent
discharge line, but the two effluents cannot be combined prior to discharge due to differences in
NPDES compliance monitoring.
The remainder of the overall Brunswick H2GO water supply project will be permitted under a
separate CAMA General Permit and Section 404-401 Nationwide Permit. These remaining project
components include: 1) five well sites, each with two wells and ancillary structures, spaced about
one mile apart; 2) a 4.0 MGD Reverse Osmosis WTP and ancillary structures at the Gregory Rd site
aquired last year for this purpose; 3) raw water lines connecting the well sites to the WTP; and 4)
a potable water line from the WTP to the existing H2GO water distribution system. These
components are located from Gregory Rd westward, far inland from tidal influence. The only
CAMA-jurisdictional Public Trust Water affected by these components is Jackeys Creek at US -17
(Ocean Hwy), which may be navigable by kayak. The proposed raw water lines will cross several
other very small non -tidal freshwater streams (Morgan Br, Sturgeon Cr, unnamed tributaries and
ditches) and non -tidal wetlands subject to Section 404-401 regulation but not subject to CAMA
regulation.
Notification letters are being mailed by Certified Mail to the property owners adjacent to the
Brunswick River near the discharge site, along with copies of this permit application. These parcel
owners include NC State Ports Authority, which owns the riverfront land; D.R. Horton, Inc., current
developer of residential lots along the north edge of the easement; and an older single-family
house on a wooded lot immediately south of the easement. Cape Fear River Watch serves as the
steward for a conservation easement on the NC State Ports parcel. A copy of the notification
letter sent to the three adjacent property owners (plus Cape Fear River Watch) is included with
this permit application.

9. PROJECT DESCRIPTION
The project site is located between 600 River Road and Hawkswater At The River Subdivision, adjacent to the
Brunswick River, in the City of Belville, Brunswick County. To locate the property from the Wilmington DCM Office,
travel north on Cardinal Dr. Ext. and turn left on to Market St. Drive 0.4 miles and turn right on to Martin Luther King
Jr. Parkway (US -74W). Travel 5.25 miles and merge right on to Isabel Holmes Bridge. Go over the bridge and take a
left onto US-17S/74W/421 S towards Leland. Continue 0.96 miles and keep right on US-17S/74W/76W (Ocean Hwy).
Travel 2.0 miles and stay right, taking the Southport/Oak Island US -133S exit, then stay in the left lane and take the
left exit toward Belville US -133S. Continue on US -133S (River Road) for 1.3 miles and the property will be on the left
side.
The project is located on the west bank of the Brunswick River, just south of the Ocean Highway Bridge and is
approximately 0.53 acres. The approximate elevation is 25' above Normal High Water (NHW) in the upland project
area. The site is currently utilized as a river discharge easement and has been maintained via mowing and clipping of
upland vegetation. Existing structures include a wastewater pump adjacent to NC -133, with a buried 8" Force Main
Discharge outfall pipe from the upland area, under the wetlands, and extending approximately 350' in to the Brunswick
River. The application states the Force Main line corridor from the WTP site to NC -133 is mostly alongside public
roads (10,600 ft.), except for an off-road easement through residential neighborhoods between Chappel Loop Rd. and
NC -133 (5,900 ft.). The proposed line will be installed alongside the existing Force Main line in the existing easement.
CAMA General Permit #68043D was issued on March 6, 2017 authorizing the installation of one (1) raw water main,
one (1) finished watermain, and one (1) force main, via horizontal directional bore, under Jackey's Creek.
The project site was historically a storage area for retired military ships known as the "Mothball Fleet" in the 1940's to
1970. The Brunswick River had been widened and deepened by the Army Corps to create a turning and storage basin
for these vessels.
The existing effluent discharge line was approved via State Permit #32-90 on March 7, 1990 to the Town of Belville.
The authorization was a part of the applicant's proposal to create a sewer district for the Town of Belville and the
surrounding areas. The service area for the proposal included 1,600 single family homes and approximately 400 light
industrial and commercial operations. The Town of Belville Wastewater Treatment Plant and service lines are now
owned and operated by H2GO. The easement has been maintained and cleared of upland vegetation.
NC State Ports Authority (NC SPA) was the original owner of the property through which the existing easement runs.
The existing easement was granted to the Town of Belville by the NCSPA on December 1, 1989, for the installation of
the existing effluent discharge line. In 2001, H2GO purchased the Town of Belville WWTP and all associated
properties and easements (see Assignment and Bill of Sale), including the easement from US -133 to the Brunswick
River. The underlying property of the existing easement is now owned by D.R. Horton.
Upland vegetation within the easement consists of wild grasses, shrubs, and hardwood species located on the western
portion of the site. The northern adjacent property has been completely cleared for future development of a residential
home. The adjacent property south of the easement contains dense upland shrubs, vines, and hardwood species. The
coastal wetlands on the site includes a border of Smooth Cordgrass (Spartina alterniflora), Phragmites, Spike Grass
(Distichlis spicata), Saltmeadow Cordgrass (Spartina patens), and Groundsel Tree (Baccharis halimifolia) that is
approximately 50 ft. in width and 40 ft. in length.
The waters of the Brunswick River (in the vicinity of the project) are classified SC, by the N.C. Division of Water
Resources. The area is designated as a Primary Nursery Area (PNA), by the N.C. Division of Marine Fisheries and
these waters are CLOSED to the harvesting of shellfish. The Brunswick County Land Use Plan classifies the area as
Conservation.

PROPOSED PROJECT
The applicant is proposing to construct a Reverse Osmosis Water Treatment Plant (WTP) to connect to an existing
water distribution system serving Leland, Belville, Navassa, and adjacent areas. The purpose of this project is to
increase Brunswick County's water capacity to serve more customers. The Water Treatment Plant will be located 2.88
miles west of the Brunswick River at the end of Gregory Road in Belville, and will transmit water through 17,150 linear
feet of finished water main to the Brunswick River. The mains will be installed within road right-of-ways and private
utility easements by open cut trenching and will avoid and minimize impacts to waters and wetlands by horizontal
direction drilling and bore and jack. The applicant anticipates approximately 12 acres of total disturbed area. Four (5)
well sites are proposed to retrieve water from existing subterranean aquifers.
The applicant states that the proposed Brunswick River discharge site is along the eastern edge of the H2GO service
area, a tidal semi -tidal river with bi-directional flow and salinities varying from nearly fresh water to at least 24 g/L in
the proposed discharge area, depending on tidal stage and fresh water inflow. The Brunswick River is 1500ft wide, and
1Oft- 14ft deep (depending on tide stage) in the discharge area, 3 60f out from the river bank.
The new 16" PVC concentrate line will be installed 275' east of US -133 via horizontal direction bore and will follow
the existing effluent discharge easement toward the Brunswick River. The diffuser line will be within the 75' Estuarine
Shoreline Area of Environmental Concern as it reaches the shoreline and will continue under the Brunswick River until
it reaches the 10ft depth contour at approximately 360ft from shore. When the bore hole is complete out in the water,
the concentrate line will be floated out by barge and fed through the bore hole back towards shore. The line will then
be connected to the main line in the upland area on shore.
As stated by the applicant, a proposed diffuser pipe will be located at the end of the 16" PVC concentrate line at a 45 -
degree angle to release RO wastewater in to the Brunswick River. The proposed diffuser is a 35ft long pipe with four
(4) discharge port pipes protruding one foot above the riverbed and angled downstream at 45 degrees. Rubber
"duckbill" valves will be fixed to each discharge port to help keep out sediment. The diffuser pipe will be lowered in to
the river by barge and placed at the bottom of an excavated trench and covered with riprap.
A turbidity curtain will be installed several days prior to the start of the excavation process to limit suspended sediments
to the project area. The bottom curtain will be approximately lft off the river bottom and will be anchored by bottom
anchors or six (6) temporary wood pilings. The turbidity curtain will be marked by flashing lights from floating buoys
and temporary pilings to aid in safe navigation around the project site. Excavation equipment will reach over the
turbidity curtain during operation and installation. The turbidity curtain will be removed seven (7) days after the
diffuser has been completely installed and secured in the trench.
The applicant proposes to excavate a 5.5ft deep, l Oft wide, and 84ft long bottom trench for the placement of the new
diffuser assembly. The trench sides will be graded so that the top of the trench (at existing grade) is 40ft in width and
124ft in length. The excavation of the trench will be accomplished using the bucket to barge method. When the
diffuser is in place, the trench will be backfilled with clean #67 stone fill to a height of approximately 36" from the
trench bottom to cover the diffuser. Approximately 24" of clean NCDOT Class 1 riprap will be placed on top of that to
the existing grade (- l Oft) to secure the diffuser assembly at the bottom of the Brunswick River. Clean NCDOT Class A
riprap will be hand placed around each "duckbill" diffuser head to complete installation.
Approximately 470 cu. yds. of excavated river bottom material, will be deposited on to a floating barge (with a skirt)
and transported to an offload area where it will be transferred to trucks on shore. A contractor will then transport the
dredge material from shore to a l 00ft by 200ft disposal site owned by H2GO. Backfill material will be loaded on to the
barge from land and transported to the trench to be deposited.

Brunswick Regional Water & Sewer H2GO c/o Gerald Pottern
Page Four
The proposed diffuser will be protected by a debris deflector located 4ft-20ft upstream of the diffuser. The deflector
will be installed after the removal of the turbidity curtain and will comprise of a row of four (4) permanent pilings
spaced 11 ft apart. The pilings will be "wet jetted" to a depth of 20ft below the river bottom, with the top of the pilings
at 2ft above Mean High Water (MHW). The floating cross beams, measuring approximately 35ft in width, will be
attached just below the MHW line. The debris deflector will be positioned at an angle toward the channel, with the
landward end piling 20ft from the connection point of the diffuser, and the waterward end piling 4ft from the terminal
end of the diffuser. One additional permanent piling will be installed approximately 4ft from the concentrate
line/diffuser connection point, using the same method as the deflector pilings. The permanent pilings will all have solar
powered warning lights and signs marking their locations.
10. ANTICIPATED IMPACTS
The technique of horizontal directional drilling will result in no direct excavation or fill impacts to wetlands or waters.
Clearing and trench excavation is expected to cause 7.5 acres of disturbance in upland areas where horizontal
directional drilling is not possible or not applicable. H2GO's discharge easement from US -133 to the river is not open
to public use.
Excavation of the diffuser trench by bucket to barge method is expected to cause temporary turbidity and siltation,
however, the impacts will be limited to the project area by the. installation of turbidity curtains. Placement of stone
riprap within the trench is anticipated to have a low impact on benthic invertebrate and vertebrate species. Natural
sediment in this area contains sands and silts that is not high quality habitat for benthic fauna or aquatic vegetation.
Five benthic samples taken in November 2013 in the proposed diffuser area revealed very low abundance and diversity
of benthic macroinvertebrates. Two samples contained no macro invertebrates, and three samples yielded two
Polychaete worms, one marsh clam, and one Amphipod. Introduction of riprap may provide habitat for estuarine
mollusks, crustaceans, bottom -dwelling fishes, and other aquatic life. The site has had a prior history of being disturbed
by dredge activities for the "Mothball Fleet" and the existing effluent discharge line.
A SEPA Environmental Assessment was circulated in 2015 by the applicant among National Marine Fisheries, US Fish
& Wildlife, NC Heritage Program, NC Wildlife Resources Commission, DENR Wilmington Regional Office, NC
Division of Coastal Management, and NC Division of Marine Fisheries. The applicant states that comments from the
agencies concluded low impact to fisheries, shellfishes, wildlife, endangered species, or water quality. Due to changes
in SEPA law in 2015, SEPA review was discontinued before the Environmental Assessment was finalized. The
installation of an RO discharge pipe to the Brunswick River without proper plant operations could create potential
water quality degradation with a resulting impact on animal resources, including the Short -nosed Sturgeon.

Form DCM MP -1:
(TP Effluent Discice
5.c. Construction Methods, Sequence, Equipment:
The new RO concentrate line diffuser pipe will be installed via open cut technology for the majority of the new
line. Directional drilling will be used at four locations along the new RO concentrate line:
• The first will be at Station 65+39 near the intersection of Two Pine Road and Eastwood Lane as shown
on attached Drawings C-1.02 and C-1.03. This directionally drilled section will be approximately 700
feet long, beneath wetland GS.
• The second will be at Station 110+35 near the intersection of Highway NC 133 and Morecamble
Boulevard SE and Eastwood Lane as shown on attached Drawings C-1.04. This directionally drilled
section will be approximately 290 feet long.
• The third will be at Station 114+73 near the intersection of Highway NC 133 and the sewer lift station
as shown on attached Drawings C-1.04. This directionally drilled section will be approximately 140 feet
long.
• The fourth directional drilling section is described below and is the only drilling section related to an
Area of Concern under this CAMA major permit application (wetland GQ).
The fourth directionally drilled pipe will be from a location approximately 275 feet east of Highway 133 and
extend out approximately 800 feet to the submerged diffuser location. The proposed directionally drilled pipe
profile is shown on Drawing C-1.05. The drilling pit will be set up on a high point elevation of approximately 20
feet msl and will be approximately 10 feet higher than the 100 year floodplain elevation. Fused PVC pipe (16 -
inch diameter) will be used with fusing occurring on the shore in the existing H2GO utility easement. The
drilling head will be advanced to the diffuser location. The PVC pipe will then be floated out onto the river and
prevented from significant movement using floating barge(s) and/or temporary wood piles. The fused pipe
will be pulled back from the water down into the borehole and back to the drilling pit in a controlled manner.
The pipe will be filled with river water as it is pulled to sink the pipe to the bottom. At the end of the pull, the
fused PVC pipe end will be located in the area where the 45 -degree elbow is shown on the Plan Sheets. The
pipe end will be marked with a temporary float.
The river bottom diffuser profile and depth is shown on Drawing C-1.05. The diffuser assembly will be installed
"in the wet" by divers without the need for a cofferdam. A barge will be used to transport the 35 -foot long,
HPDE diffuser assembly to the installation location. The diffuser assembly will include the 45 -degree elbow
already attached. The bottom trench will be - 5.5 feet deep, 10 feet wide and 84 feet long. Top trench width
to be 40 feet and top length to be 124 feet. The trench will be excavated in the existing river bottom to allow
burial of the new diffuser assembly. Bottom trench excavation will be accomplished using a floating barge and
long reach excavator bucket or clam -shell bucket (- 3.5 feet wide).
A turbidity curtain will be installed surrounding the excavation and diffuser areas. A product cut sheet on the
proposed turbidity curtain is attached. The bottom of the curtain is approximately 1 foot off the river bottom
to avoid disturbing the river sediments in the curtain area. The turbidity curtain will be held in place by either
bottom anchors or temporary wood piles driven into the river bottom. The excavating equipment will reach
over the turbidity curtain.

Once the trench is excavated and leveled using leveling rods, the diffuser assembly will be lowered in place by
the crane and divers will manually guide the diffuser in position in the trench and connect the directionally
drilled plain end pipe to the 45 -degree elbow. Connection details are showing in the attached Drawings. After
connection of the two pipes, the divers will connect the duckbill diffusers and then stone on the barge(s) will
be placed over the diffuser assembly to complete the installation. A product cut sheet on the diffuser
assemblies ("duckbill") is attached.
After the diffuser assembly is installed, the turbidity curtain will be removed. At this point the wood piles for
the debris deflector will be installed by a pile driver or wet jetting technique to a depth of 20 feet below the
river bottom with the top of the pile approximately 2 feet above high tide. The floating cross bars between the
wood piles would then be attached and the warning signs installed. The four deflector piles will be located
upstream of the approximate location of the four bottom diffuser duckbills thus identifying the location of the
bottom diffusers. Once the deflector piles are installed the construction would be complete. It is anticipated
that the direction drilling and diffuser installation work can be completed in approximately 3 to 4 weeks
(depending on weather).
5.f. Land Disturbance Area:
The entire length of the RO concentrate line is approximately 17,450 lineal feet (from starting point at WTP
fence line to river diffuser). Of this length, approximately 1,930 feet will be directionally drilled. Thus, the
length of line to be open cut is approximately 15,520 lineal feet. Based on an average open cut disturbance
width of 20 feet along the open cut areas of the project length (15,520 ft) and including some disturbance for
the directional drilling pits, the estimated land disturbance is 7.5 acres based on the attached drawings.
However, the middle segment of the project from US -17 eastward to the Belville WWTP (approximately 6,300
ft) is being permitted and installed separately along with a new wastewater forcemain, in order to minimize
construction impacts and costs. The two roadside ditch/stream crossings at Ploof Rd and Chappell Loop Rd are
within this middle segment; neither is a CAMA Public Trust Water. Subtracting the land disturbance in this
middle segment (2.9 acres) leaves 4.6 acres of "new" disturbed area.
5.g. Public Easement or Access Encroachment: H2GO's existing 30 -ft wide effluent discharge easement from
NC -133 to the river is not open for public access to the river. Private lands border the effluent easement to
the north and south, and to the east it crosses the Brunswick River floodplain (FEMA 1% base flood elevation =
9 feet, NAVD-88) which is owned by the NC State Ports Authority. The State Ports parcel extends
approximately 90 feet inland from the outer edge of the tidal marsh in this area. The Cape Fear River Watch
serves as steward for a conservation easement on this parcel.
6.a. Project Narrative:
The proposed Brunswick H2GO Reverse Osmosis Water Treatment Plant (WTP) project is a potable water
treatment plant using groundwater from five pairs of proposed wells tapping into the Lower PeeDee and Black
Creek aquifers as sources. These aquifers contain brackish water and are not currently tapped for any other
uses. Furthermore, they are separated from the shallower freshwater aquifer above (Castle Hayne) by dense
confining layers. Withdrawal from the deep brackish aquifers should not affect existing or future private wells
tapping into the freshwater aquifers (Groundwater Management Associates, 2013). The new WTP will connect
to H2GO's existing water distribution system serving Leland, Belville, Navassa, and adjacent areas. 1-12GO will
no longer routinely use Brunswick County for daily water supply, although an emergency connection will be
maintained. This will free up approximately 2 MGD (current daily demand) of Brunswick County water for
other customers. __-

The WTP will be built with a 4.0 MGD initial capacity, and may be expanded to 8.0 MGD if needed in the
future. The Reverse Osmosis (RO) process will use synthetic membranes and pressure to separate the raw
water into approximately 80 percent potable fresh water and 20 percent concentrated RO reject (saline)
wastewater. At 4.0 MGD operating capacity and 80% efficiency the WTP will require about 5.0 MGD of raw
groundwater and will discharge 1.0 MGD of RO concentrate water. Based on the measured salinities of the
two aquifers and expected RO treatment efficiency, the expected salinity of the RO reject wastewater to be
discharged into the Brunswick River will be 25 to 32 g/L, or about 75 to 95 percent of seawater salinity.
The proposed Brunswick River discharge site is the along the eastern edge of the H2GO service area, a tidal
river with bi-directional flow and salinities varying from nearly fresh to at least 24 g/L in the proposed
discharge area (Groundwater Management Associates, 2013) depending on tidal stage and freshwater inflow.
The river is 1500 ft wide and 10 to 14 ft deep (depending on tide stage) in the discharge area, 360 feet out
from the riverbank. It was artificially widened by the Army Corps of Engineers in the 1940s for storing retired
military ships, creating a "bench" on either side of the original 400 foot wide channel.
The proposed diffuser is a 35 ft long pipe anchored horizontally on the riverbed with four discharge port pipes
protruding one foot above the riverbed and angled downstream at 45 degrees to achieve rapid mixing. Based
on Cormix modeling under a variety of river flow conditions, the diffuser will achieve 40x or greater dilution
within the first 10 meters from the port outlets. A Tideflex® rubber "duckbill" valve on each diffuser port will
help keep out sediment. A row of four pilings will mark the diffuser location and support a debris deflector to
help protect the diffuser ports from boats, anchors, and drifting logs.
The effluent pipeline will extend approximately 17,150 feet from the proposed WTP site on Gregory Rd to the
west bank of the Brunswick River. The majority of it will be installed alongside roadways (Gregory Rd, US-17,
Ploof Rd, Chappel Loop Rd, and River Rd) and the remaining off-road segments will share the existing right-of-
way with Brunswick H2GO's existing Belville wastewater treatment plant (WWTP) effluent discharge line.
Most segments will be installed by trenching; other selected segments (including streams, ditches, wetlands,
and the riverbank and riverbed areas) will be installed by directional drilling. The staging area for drilling near
the riverbank will be above the 100-year flood hazard elevation of 9 ft (NAVD-88). The diffuser pipe and ports
structure will be carried to the diffuser site on a barge, river sediment will be excavated to the specified depth
(using turbidity curtains to contain turbidity), and the structure will be lowered to the bottom and connected
to the buried dischage line by construction divers. Excavated sediment will be taken to an upland site for
disposal, and concrete and ballast rock will be placed around the diffuser to anchor it. Construction methods
and sequencing are described further in Form MP-1 Section 5.c.
The ballast rock will provide a patch of hard substartum in a river reach dominated by silt and fine sand with
minimal hard bottom habitat. This ballast rock may provide habitat for estuarine mollusks, crustaceans,
bottom-dwelling fishes, and other aquatic life, although the low ambient oxygen concentrations that occur
periodically at the bottom in this area may limit the habitat benefits of the placed rock. Five benthic samples
collected from the proposed diffuser area in November 2013 using a LaMotte dredge (6 x 7.5 inches area x 3
inches deep) revealed very low abundance and diversity of benthic macroinvertebrates (William Kirby-Smith,
Duke Marine Laboratory, 2014). Two of the five samples yielded no macroinvertebrates, and the other three
samples yielded two Polychaete worms (Lumbineridae and Capitellidoe), one Marsh clam (Rangia), and one
Amphipod (Gammaridae).

The sediment from all five samples was primarily silt, clay, and fine sand with 16 to 18 percent organic matter,
and exuded a hydrogen sulfide odor indicating anaerobic conditions. However, water quality samples taken in
November 2013 at 8 to 10 foot depth revealed dissolved oxygen concentrations in the 6 to 8 mg/L range, and
salinities in the 15 to 24 g/L (or PSU) range. Monthly salinity samples collected from Aug 2012 to Aug 2013 by
NC-DWQ at 3 ft depth and 1,000 ft upstream of the discharge site ranged from 0.1 to 13.9 g/L. These data
suggest a "salt wedge" effect in the Brunswick River, with seawater moving in and out with the tides in deeper
water, and freshwater from the Cape Fear River and other feeder streams occupying the upper layers. Storms
and seasonal dynamics (e.g. rapid surface cooling) result in occasional mixing of the layers. The artificial
widening of the river in the 1940s has probably contributed to anaerobic bottom conditions by reducing flow
velocities and increasing the hydraulic retention time.
A SEPA Environmental Assessment (EA) for the project was circulated among state and federal agencies during
2015. Review comments regarding potential impacts from the discharge were received from National Marine
Fisheries (F.Rohde), US Fish & Wildlife Service (J.Ellis), NC Natural Heritage Program (A.Weakley), NC Wildlife
Resources Commission (M.Dunn), DENR Wilmington Regional Office, NC Division of Coastal Management
(S.Staples), and NC Division of Marine Fisheries (S.Jenkins), among other agencies. After extensive
consultation with agency biologists, all were satisfied that the discharge and diffuser as proposed would not be
likely to adversely affect fisheries, shellfishes, wildlife, endangered species, or water quality in the receiving
stream. The increase in salinity will be small and localized, and the species exposed to it are euryhaline
species adapted to wide salinity fluctuations. Due to changes in the SEPA law in 2015, SEPA review was
cancelled before the EA-FONSI was finalized, but the SEPA review comments and applicant responses are
appended to this CAMA application.
This CAMA Major Permit application addresses the impacts of the effluent discharge line from the proposed
WTP on Gregory Rd to the proposed effluent diffuser in the river. This includes 10,600 ft of effluent pipeline
along roadways, 6,550 ft off-road within an existing wastewater easement through residential neighborhoods,
and 400 ft under the river bed. Plans and impact calculations presented herein are based on these project
components. However, the middle segment between US -17 and the Belville WWTP (6,300 ft) is being
permitted and built separately along with a parallel wastewater force main line, to minimize construction
impacts and costs. Other components of the WTP project not included in this application include the five well
sites (each 1.2 acres with two wells, a pump house, and perimeter fence), raw water lines from the wells to the
WTP (32,400 feet), the WTP site facilities, and potable water connector into the H2GO distribution system.
These will be permitted under a separate CAMA General Permit and Section 404-401 Nationwide Permit.

Tideflex' Widebill Effluent Diffuser
Features & Benefits
• Less expensive than standard duck bill check valve
• Improved dilution
• No need to oversize in order to reduce headloss
• No additional headloss at peak flow
Materials of Construction
• Available in Buna-N, Neoprene, EPDM
Tideflex Widebill Effluent Diffuser Valves are an innovative
choice for effluent diffuser systems. The newly patented
"widebill" check valve design has several unique benefits, the
most significant being cost savings. Widebill Tideflex
Diffusers are less expensive than a standard duck bill check
valve. Also, the all -elastomer construction is flexible and non -
fouling, making them suited for long-term, maintenance free
service.
Other major benefits of the Tideflex Widebill Effluent
Diffuser include:
• Elliptical Jet has greater width/depth ratio yielding better
dilution.
• Enhanced jet velocity at flows below peak flow for
improved dilution.
• No need to oversize Tideflex Diffusers to reduce headloss.
• No additional headloss at peak flow (same headloss as fixed-
diamter port/riser).
• Widebill diffusers open to and beyond nominal pipe diame-
ter at peak flow.
• Easily retrofit to existing diffusers without oversizing
Tideflex.
• Smaller diameter risers also compound the cost savings.
