The Corps will evaluate this application and a decide whether to issue, conditionally
issue, or deny the proposed work pursuant to applicable procedures Section 404 of the
Clean Water Act (33 U.S.C. 1344).
Location
A portion of the project is located within the limits of the City of Jacksonville while the
remainder of the project is located outside the City limits, Onslow County. The existing
treatment facility and sprayfields are located west of Jacksonville comprised of
approximately 6500 acres between Five Mile Road and Blue Creek Road with drainage
to Southwest Creek, Stewart Creek, and Deep Run. The proposed flow equalization tank
is located within the City limits of Jacksonville with drainage to Chaney Creek and Sandy
Run Branch. The existing LTS can be located at 34 47.22 N 77 34.12 W and the
proposed flow equalization tank can be located at 34 45.31 N and 77 25.19 W.

Existing Site Conditions
The existing Land Treatment System site contains the existing storage and treatment
lagoons, the administration building, the equipment storage building, and numerous
auxiliary structures associated with the treatment process. The LTS contains several
miles of buried transmission mains, irrigation header and lateral pipes which transport the
pretreated effluent to approximately 19,000 sprinkler heads. The land surrounding the
treatment works and the land currently being irrigated is managed as a pine plantation.
The land surface of the current LTS property slopes eastward toward Deep Run with
elevations ranging from 30 to 90 feet above mean sea level. As you head down gradient
toward Deep Run the vegetation will change to a more bottomland hardwood system.
The land surrounding the LTS is rural with sparse housing and the majority of the land
being utilized for farming and silviculture.
The location of the proposed flow equalization tank contains two sanitary sewer lines and
several man made structures including the main sewer pump station. The vegetation
within this parcel is primarily pine forest. The land slopes generally to the south and
west towards Chaney Creek but does lie above the 100 year floodplain. The site
elevation varies from 0 to 15 feet above mean sea level. The surrounding land use is an
urban stretch of Highway 17 in the heart of Jacksonville.
Parcels 2, 3, 11, 12, 23 and 62 which are proposed for land treatment expansion areas
have exsting unpaved access roads and drainage ditches. Parce162 contains a cementary
which was determined as not eligible for the National Register of Historic Places
(NRHP). The majority of the expansion area if forested with the exception of a couple
small agricultural fields on Parcel 12. Forests within the project area can be divided into
the following communities: Pine plantation, mesic mixed hardwood, small depression
ponds, bottomland hardwood, and pocosin. Relief of Parcels 2, 3, and 23 is slight and
elevations range from 62 to 94 feet above mean sea level. The land surface of Parce162
is moderately sloped generally to the southwest towards Southwest Creek with elevations
ranging from 44 to 78 feet above mean sea level. As with the existing LTS site, the
surrounding land use is rural primarily utilized for farming and silviculture.
Applicant's Stated Purpose
The applicant's stated purpose to provide the City of Jacksonville with the increased
storage and treatment capacity to be able to handle the increasing demand on the system.
The City currently is under a Special Order of Consent from NCDENR-DWQ which
requires the City to pursue plant expansions and improvements within six years from the
issuance of the Order in May of 2005. The need for the plant expansion stems from the
fact the LTS is City's sole treatment system which was selected as the preferred treatment
alternative in the 201 Facilities Plan.
2 Version 12/12/05

Project Description
Expansion of the LTS facility to increase treatment capacity from an average daily flow
of 6.0 mgd to 9.0 mgd will involve:
1. Developing a new effluent storage lagoon with a nominal capacity of 180 to 365 MG
located on adjacent properties,
2. Pumping and piping improvements to convey flow between the new effluent storage
lagoon and the existing storage lagoon system,
3. Construction of new Flow Equalization Tank to be connected to the existing force
main,
4. Expansion of the existing spray irrigation system using approximately 319 acres
within the existing LTS property,
5. Upgrades to the existing spray irrigation areas to enhance their suitability for spray
irrigation, and
6. Acquisition and expansion of the spray irrigation system on approximately 220 acres
of property adjacent to the existing LTS.
Construction of the storage lagoon. Parcels 11 and 12 contain a total of 75 acres of
wetlands. An estimated 24.4 acres of forested headwater wetlands and 4001inear feet of
intermittent channelized stream will be impacted through the construction of the storage
lagoon. Red maple,sweetgum and swamp chestnut oak dominate the above-referenced
wetlands. The remaining approximate 50 acres of wetlands on Parcels 11 and 12 will not
be impacted as part of this project.
Irrigation Spray Field Expansion. Where practical, piping will be placed in existing road
corridors, through uplands and previously cleared areas. However, some of the
transmission mains and header pipes cannot avoid wetlands. Permanent forested wetland
impacts associated with irrigation spray field expansion will total approximately 1.2 acre.
These impacts will be permanent because of construction of access roads over the top of
buried piping. Permanent conversion from forested to herbaceous wetland caused by
piping installation will tota15.9 acres. These permanent conversions will result from
clearing of corridors through which irrigation piping will be installed. These areas will
remain wetland but will be maintained in an herbaceous state to allow access for repairs
and normal maintenance.
Flow Equalization Tank Construction. The construction of the proposed Flow
Equalization Tank site and associated force mains will result in permanent conversion of
approximately 0.06 acres of forested wetland to herbaceous wetland and temporary
impact to approximately 0.17 acres of existing herbaceous wetlands.
To offset the projected unavoidable wetland impacts the applicant has designed the
following mitigation proposal. The applicant proposes a combination of onsite wetland
preservation and offsite wetland restoration.
Version 12/12/05

To mitigate for the permanent conversion of over 5 acres of forested wetlands the City
proposes to preserve 51 acres of wetlands and 37 acres of upland inclusions on Parcels 11
and 12. This represents a 9:2:1 mitigation ratio for the permanent conversion.
The City proposes to compensate for the permanent forested wetland impacts by
preserving approximately 640 acres of wetlands within Parcels 2, 3, and 23 and by
purchasing 25.56 credits from the Hoffman Forest Mitigation Bank. The combination of
preservation on Parcels 2, 3, and 23 and the purchase of credits at Hoffman Forest
provide 1 acre of restoration and 25 acres of preservation for each acre of permanent
impact.
In order to mitigate for the stream impacts necessary for lagoon construction, the City
proposes to create approximately 400 feet of intermittent channel.
Detailed plans of the project proposal can be viewed at the U.S. Army Corps of Engineer
Wilmington District Office. For more information to view the plans, please contact Brad
Shaver, Regulatory Specialist at [phone] or Gwen Robinson, Regulatory Program
Assistant at [phone].

APPENDIX G -MITIGATION PROPOSAL
A wide of variety of compensatory wetland mitigation alternatives have been
evaluated for the unavoidable impacts to 25.56 acres of forested wetlands and 5.54
acres of permanent conversion of forested wetlands to an herbaceous community
associated with the expansion and upgrade of the LTS. The alternatives included
both on and offsite wetland restoration, enhancement and preservation, North
Carolina's Ecosystem Enhancement Program and the Hoffman Forest Wetland
Mitigation Bank.
A brief summary of the mitigation alternative evaluations are provided below
followed by the mitigation proposal, which also includes mitigation for unavoidable
impacts to 400 linear feet of intermittent channel on the Proposed South Lagoon
site.
Onsite Evaluations
Onsite mitigation opportunities evaluated include creation, restoration,
enhancement and preservation. Wetland creation, restoration and enhancement of
hydrologic regimes internal to the LTS and adjacent to existing irrigation fields
could potentially reduce infiltration rates in the existing spray zones. This
interference would be counter productive to the expansion, resulting in greater
potential impacts to accommodate the drop in irrigation rate. Therefore, these
options were dismissed. However, there remains the potential for wetland
restoration within Parcel 12 and wetland preservation within. Parcels 2, 3,11,12 and
23.
Two areas within Parcel 12 were identified as potential wetland restoration /
creation sites based on a preliminary evaluation (Figure G-1). Area 1 is
approximately 6.2-acres in size and is partially covered by hydric soils, adjacent to
existing wetlands and water currently following offsite could potentially be diverted
to hydrate the site. Area 2 is approximately 2.1-acres in size and is primarily a
fallow agricultural field located between the natural gas ROW and the eastern side
of the proposed South Storage Lagoon.
However, after further evaluation, use of Area 1 or Area 2 on Parcel 12 does not
appear to be feasible. Area 1 would require extensive earthwork including
excavation of approximately 1-3 feet of soil across the site so that water from the
adjacent ditch could be intercepted and used to hydrate the site. In addition, Area 1
is planned to be a contractor lay-down area during construction of the South
Storage Lagoon. If Area 1 is used for mitigation, another contractor lay-down area
would need to be identified or the mitigation postponed until after the construction
of the lagoon.
Field verification of existing topographic maps suggests Area 2 does not have a
large enough watershed to provide the required hydrology needed to create a
wetland. across the site. However, the potential to establish a small intermittent
G-1

stream channel does exist. See the recommended location for potential stream
restoration in Figure G-1 and the stream mitigation proposal below.
Parcels 2, 3, and 23 contain approximately 584,124, and 90 acres of wetlands,
respectively, which are not suitable for irrigation. Figure G-2 shows a nearly
contiguous 640 acre tract of wetlands that is located along the southern property
boundary of Parcels 2, 3, and 23. These numbers exclude access roads and the
power ROW which crosses the southern portion of Parcel 2. Preservation of the
above referenced 640 acres could be a component of a larger mitigation package.
Additional onsite preservation opportunities exist on Parcels 11 and 12. Combined,
these parcels contain approximately 51 acres of wetlands which are outside of the
limits of construction specified for the proposed lagoon (Figure G-3). These
wetlands also contain approximately 37 acres of upland inclusions which create a
somewhat unique habitat in the Southwest Creek flood plain. Preservation of the
above referenced 88 acres of wetland /upland mosaic could be a component of a
larger mitigation package.
Offsite Evaluations
Preliminary assessments were conducted at approximately 20 sites within Onslow
County, with some being as far away as 15 miles to the east of the site near the
Hoffman Forest. The sites were selected because they showed favorable mapped
conditions, including: little topographic relief, hydric soils, and adjacency to existing
wetlands and streams. These potential restoration /creation sites were evaluated
to further refine the search for potential mitigation acreage. Based on this process,
a portion of Parcel 22 represented the most practical property to conduct wetland
restoration in the vicinity of the project area (Figure G-4).
Parcel 22 is approximately 577 acres in size. Most of this site is suitable for
wetland restoration /creation and, as such, has the potential to provide wetland
restoration /creation opportunities in excess of what is needed for the LTS
Expansion and Upgrade Project. However, the property is currently being sold to a
developer and the $3.2 million sale price makes the property cost prohibitive.
The Brookview Lagoons, located within the 100-year flood plain of the New River,
were evaluated for potential use as a wetland restoration site (Figure G-5). These
man-made lagoons, which total approximately 21.5 acres in size, served as part of
the City's wastewater treatment system until the late 1970s.
Approximately 26 acres of wetland restoration could be achieved at this site based
on lagoon construction plans provided by the City. Restoration of the lagoons would
require the placement of approximately 100,000 cubic yards of fill material in the
lagoons and the grading down of the lagoon berms.
The Brookview Lagoons represent an excellent opportunity for wetland mitigation
that could directly affect the water quality of the New River; however, the wetland
restoration at the Brookview Lagoons would be out-of-kind. The wetlands being
G-2

impacted as a result of the project are palustrine/nontidal and those which would
result from the mitigation would be riverine/tidal.
In addition, hauling the soil needed to fill the lagoons would be cost prohibitive and
would significantly increase the amount of traffic through a residential
neighborhood. Approximately 40 dump truck loads of material per day for 260 days
would be needed to provide the required fill. Not only is this a massive undertaking
due to the amount of fill required but the transport of the material will have a
negative impact on the communities and road infrastructure leading into the
Brookview Lagoons. For these reasons, mitigation at this site is not advised.
Two abandoned lagoons within Northeast Creek Park were evaluated for their
potential use as mitigation sites (Figure G-6). Unfortunately, since being
abandoned, wetlands have developed within the bottom of each lagoon with the
exception of a 2.3 acre open water system that still exists within the lagoon to the
south. The Northeast Creek Park Lagoons were eliminated as potential mitigation
sites because of the limited opportunity to conduct wetland restoration.
Currently, the Hoffman Forest Wetland Mitigation Bank has 8 credits (acres) with
another 30 credits likely to become available within the next two months. The
additional credits will be released by the MBRT once new water control structures
are installed.
The North Carolina Ecosystem Enhancement Program (EEP) was not considered
based on agency response on other projects.
Proposed Mitigation Package
Wet/and Mitigation
In order to mitigate for the unavoidable permanent wetland impacts associated with
this project, the City proposes a combination of onsite wetland preservation and
offsite wetland restoration.
To mitigate for the permanent conversion of approximately 5.54 acres of forested
wetlands the City proposes to preserve approximately 51 acres of wetlands with 37-
acres of upland inclusions on Parcels 11 and 12 (Figure G-3). Preservation of the 51
acres represents a 9.2:1 mitigation ratio for permanent conversion while not
considering the ecological value of the uplands. The above-referenced acreage also
provides buffer along one side of Southwest Creek and Stewart Branch for
approximately 4,900 and 4,350 linear feet, respectively. The buffer varies in width
from 30 to 1,300 feet wide along the two streams.
The City proposes to compensate for the permanent forested wetland impacts by
preserving approximately 640 acres of wetlands within Parcels 2, 3, and 23 (Figure
G-2) and by purchasing 25.56 credits from the Hoffman Forest Mitigation Bank. The
combination of preservation on Parcels 2, 3, and 23 and the purchase of credits at
Hoffman Forest provide 1 acre of restoration and 25 acres of preservation for each
acre of permanent impact.
G-3

Stream Mitigation
In order to mitigate for the unavoidable permanent filling of 400 linear feet of
intermittent ditched stream channel, the City proposes to create approximately 400
feet of intermittent channel as shown in Figure G-1. The proposed location of this
channel is in a natural topographic depression that is well suited for channel
construction.
The objectives of this channel creation are summarized below in terms of hydraulics
and biology.
1. Hydraulics-Reduce shear velocities to reduce excess transport of sand and
fine sediment to Stewart's Branch.
2. Biology-Provide habitat conducive to micro- and macro-fauna establishment
and allow for upstream and downstream movement on an intermittent basis.
The channel proposed for impact is approximately 4 feet wide and 1 foot deep. A
Perennial Flow assessment was conducted in January 2006, which determined the
channel as intermittent. The substrate was estimated to have a Dso in the medium
sand range (i.e., 0.2 mm). There is little sinuosity (~1.1) to this channel. It appears to
have been channelized at some point in the past.
Natural channel design (NCD) methodology will be used to design and construct the
channel. Local reference information will be used to develop appropriate
dimensionless relationships for construction of proper channel plan, section and
profile appropriate for the existing valley type and slope.
• ReveQetation and Site Stabilization
The floodplain and stabilization of the stream and floodplain will be achieved
through the use of erosion control blankets and the establishment of
vegetation. Natural fiber erosion control blankets (e.g., jute) will be installed
on. the outside bend of most meanders to decrease erosion. The bottom 12
inches of fabric will be keyed into the stream bed. The remainder of the
blanket will secured through the use of metal hooks. Black willow stakes will
be installed at 3-foot spacings along the jute to secure and to expedite
revegetation along the meanders. An appropriate wetland, herbaceous seed
mix will be used to quickly revegetate the floodplain. All appropriate
standard engineering practices will be utilized to stabilize the site.
• Mitigation Monitoring
Stream monitoring will be conducted for three consecutive years following
construction. All tasks will be performed once a year during the specified
monitoring year, unless stated otherwise. The annual monitoring will be
G-4

conducted between July 1 and September 30. The following tasks will be
conducted on site.
The following activities comprise the stream monitoring plan.
1. Photographs showing an upstream and downstream view of the
stream taken from fixed stations. The photos will be taken from a
height of approximately five to six feet. Permanent markers will be
affixed at the photo site indicating the direction the photo is to be
taken. The photos and a map of their locations will be included in the
monitoring reports.
2. Channel stability will be determined by annually monitoring changes in
permanent cross-sections of selected riffle and pools, longitudinal
profile and bed material (as appropriate)
• Buffer
A maximum buffer of 100 feet from the edge of bank will be designated
except for adjacent areas where required site improvements may encroach
on this 100-foot buffer. In these areas, a minimum buffer width of 30 feet is
proposed.

3. DESCRIPTION AND PLANNED USE OF PR~Pnsl= n pRn i~rr
a. List all development activities you propose (e.g. building a home, motel,
marina, bulkhead, pier, and excavation and/or filling activities).
Effluent Storage Lagoon
Expansion of the Land Treatment System facility to increase treatment capacity
from an average daily flow of 6.0 MGD to 9.0 MGD will involve developing a new
effluent storage lagoon with a nominal capacity of 180 to 365 MGD located on City
owned properties (Parcels 11 and 12) adjacent to the existing effluent storage
lagoon. The proposed lagoon will be impounded by a dam structure located
southeast of the existing LTS facility (Figure 4-17, Final Engineering and
Environmental Assessment Report).
The dam will be constructed from the existing grade to a maximum height of 23
feet. Most of the dam however, will be approximately 16 feet high. The estimated
impoundment volume will be approximately 369 million gallons (MG) (1,132 acre-
feet). The perimeter length of dam is anticipated to be approximately 9,000 feet
(Section 4.3.2.6, Final Engineering and Environmental Assessment Report).
The proposed dam will be a modified homogenous embankment section that is
constructed primarily from borrow material obtained from the near surface upper
sand stratum located within the proposed lagoon footprint. This material will be
selectively excavated and then compacted in thin lifts to construct the
embankment. Material of this type is commonly used in the construction of earth
embankments, and exhibits beneficial excavation, placement, and compaction
characteristics. In addition to the main embankment section, there may be a need

~'~ to construct stabilizing embankment berms to achieve the required stability for the
proposed slopes. Upon completion, the slopes of the dam are anticipated to be
covered with a turf layer, established through topsoil, seeding, and temporary turf
reinforcing mats. The purpose of the turf cover is to protect the primary material
from erosion, and to provide for easier inspections of the embankment.
The dam will be designed in accordance with the guidelines established by the North
Carolina Department of Environmental and Natural Resources, Division of Land
Resources, Dam Safety Section.
Pretreatment Facility Expansion
The proposed upgrade and expansion involves the construction of a third treatment
train which will parallel the existing Train Nos.1 and 2, as shown on Figure 4-16 in
the Final Engineering and Environmental Assessment Report. The new train will be
designed and sized similarly to the existing treatment trains and will include four
separated treatment cells. Cell A will contain completely mixed wastewater and will
have a top of berm dimension of 290 ft x 290 ft. The final volume of Cell A will be
4.5 MG. Cells B through D will be separated by floating baffle curtains and together
they will have a top of berm dimension of 290 ft x 520 ft. The combined volumes of
Cells B-D will be 3.0 MG.
Irrigation Spray Field Expansion
i
To increase the treatment capacity of the LTS, the spray irrigation system will be
expanded to include suitable soil areas within the exiting LTS and Parcels 2, 3, 23,
and 62. The suitable soils were identified through a series of field investigations
and total 480 acres within the existing LTS and 221.6 acres within Parcels 2, 3, and
23.
Pre-treated wastewater will be supplied to the expansion sites within Parcels 2, 3,
23, and 62 by a new transmission main and header pipelines having a total length of
6.7 miles (Section 4.4.3, Final Engineering and Environmental Assessment Report).
These pipelines will connect the expansion sites to the 36-inch transmission main in
the existing land treatment system. Within the expansion sites, laterals will be
installed on 80-foot centers to transport the wastewater to the sprinkler head
assemblies for spray irrigation. Piping improvements within the existing LTS will
connect the expansion areas to the existing header pipelines. As with the areas
within Parcels 2, 3, 23, and 62, the laterals will be on 80-foot centers and they will
transport wastewater to newly installed sprinkler heads.
All below grade expansion piping will be installed using conventional overland buried
pipeline construction techniques. Once the pipe has been placed and tested the
trench will be backfilled with the excavated topsoil. No surplus of soil from the
trenching of the header or transmission main pipelines is anticipated.

Flow Equalization Tank
The expansion will involve the construction of a new flow equalization tank to be
connected to the existing force main and located approximately 600 feet southeast
of the main pump station on City of Jacksonville property (Section 4.2.7.2, Final
Engineering and Environmental Assessment Report). The flow equalization tank will
be located between the groundwater wells that were constructed on this property
but would not encroach on the required well head protection zones. The flow
equalization tank will be connected to the main pump station by a newly constructed
20-inch influent pipeline and an existing 48-inch sanitary sewer which will carry
effluent back to the pump station.
Construction of the flow equalization tank will involve the permanent clearing of
approximately 0.5 acres of mixed forestland. However, the tank location was
chosen to avoid wetlands. All proposed piping will be installed below grade, and
once the pipe has been tested, the trench will be backfilled with the excavated
topsoil. No surplus of soil from the trenching of the pipeline or the construction of
the flow equalization tank is anticipated.
Auxiliary Features
The upgrade and expansion will involve pumping and piping improvements to convey
flow between the new effluent storage lagoon and the existing storage lagoon
system. Anew gravity flow pipe will be installed to connect the East and West
~'_ Lagoons to the South Lagoon. This will allow the South Lagoon to drain down to a
level equal to the bottom of the East and West Lagoons at the connecting pipes.
The pipeline will be installed using conventional overland buried pipeline
construction techniques, and once the pipe has been placed and tested, the trench
will be backfilled with the excavated topsoil. No surplus of soil from the trenching of
the connecting pipeline is anticipated.
b. Is the proposed activity maintenance of an existing project, new work,
both?
As mentioned above in 3.a, the proposed activity involves upgrading the existing
capacity ofi the LTS from 6.0 to 9.0 MGD. In order to achieve the increased capacity
both the maintenance of existing components (i.e., pumps, control panels, etc.) and
the construction of new components, (e.g., effluent storage lagoon, Train 3, and
spray field expansion areas) are needed.
c. Will the project be for public, private or commercial use?
The LTS is operated by the City of Jacksonville to treat its municipal wastewater;
therefore this project will be for public use. The proposed upgrade and expansion
will allow the City to serve its current and future needs.
d. Give a brief description of purpose, use, methods of construction and
daily operations of proposed project. If more space is needed, please attach
additional pages.

The purpose of this project is to provide the City of Jacksonville with increased
storage and treatment capacity to be able to safely handle the increasing demand
on the City's only wastewater treatment facility.
The primary use of the LTS is to treat the wastewater from the City of Jacksonville
and to provide irrigation land for the pretreated effluent to be sprayed.
The Jacksonville LTS is responsible for the treatment and land application of the
City's wastewater. Wastewater is transported eight miles from Jacksonville to the
LTS via a 36-inch diameter force main. The wastewater is treated with hydrogen
peroxide to remove odors before flowing into the headwork facility. At the
headwork facility, the influent (raw wastewater) passes through a Huber Step
Screen where material greater than 1/8-inch in size is removed. The wastewater
then flows into an aerated grit an grease removal system where inorganic material
and floatables are removed. Wastewater then flaws into a series of aerated lagoons
where biological treatment of the waste occurs. Secondary treated wastewater
then flows into storage lagoons. The storage lagoons have a capacity of 340 MG
and provide storage of treated wastewater during periods of inclement weather,
when spray irrigation of wastewater is not feasible. The stored treated wastewater
is used to irrigate a forested 6,270 acre pine plantation. Before irrigation, this
treated wastewater is chlorinated to insure that no harmful bacteria are sprayed
onto the forest. The treated wastewater is applied in the spray irrigation fields at
the rate of 1.4 inches per week from April 1St through October 31St and 0.7 inches per
week from November 1St through March 31St
The LTS is staffed by a Plants Superintendent, achief operator, five wastewater
plant operators, a Plants Maintenance Mechanic, a Plants Maintenance Worker II and
two Equipment Operators. A Chemist is responsible for the certification of the
water and wastewater laboratory and performs all the required analyses for both
the wastewater and water sections.
The proposed project will be constructed persistent to the specifications within the
project manual and drawing set. A general description is provided in item 3.a above.
Because of the extensive clearing and soil movement necessary for the proposed
project the following mechanized equipment may be used: excavators, bulldozers,
front-end loaders/backhoes, portable batch plants, trucks, tandem dump trucks,
cranes, chipper/mulchers, tub grinders and bushhogs.
4. LAND AND WATER CHARACTERISTICS
a. Size of entire tract
N/A

b. Size of individual lot(s)
See item 2.c above.
c. Approximate elevation of tract above MHW or NWL
The land surface of the current LTS property slopes. eastward with elevations
ranging from 30 to slightly above 90 feet mean sea level (MSL) (Figure 8-13, Final
Engineering and Environmental Assessment Report). The land surface of Parcels 11
and 12 slopes generally to the south with a range in elevation from 26 feet to
approximately 65 feet above MSL (Figure 8-25, Final Engineering and
Environmental Assessment Report). Relief of Parcels 2, 3, and 23 is very slight and
elevations range from 62 to 94 feet above MSL (Figure 8-26, Final Engineering and
Environmental Assessment Report). The land surface of Parcel 62 is moderately
sloped generally to the southwest towards Southwest Creek with elevations ranging
from 44 to 78 feet above MSL (Figure 8-27, Final Engineering and Environmental
Assessment Report). Due to the flatness of the land, the physical features of a
majority of the area relate closely to the interaction of Southwest Creek and its
tributaries with various soils. Physical features of the western portions of Parcels 2
and 23 are influenced by tributaries of the adjacent Cypress Creek watershed to the
west. Natural surface drainage is moderate on much of the existing LTS land, on a
majority of the effluent storage lagoon expansion site and on the proposed irrigation
spray field expansion sites.
The flow equalization tank site slopes generally to the south and west towards the
Chaney Creek bottomland. The flow equalization tank site is relatively flat and
located above the 100-year floodplain. Ground elevation varies across the site from
0 feet above sea level at Chaney Creek to approximately 15 feet above sea level at
the northeast edge of the site (Figure 8-14, Final Engineering and Environmental
Assessment Report).
In addition to being shown in the figures within the Final Engineering and
Environmental Assessment Report, the elevations for the project area are shown
within the permit drawing set.
d. Soil type(s) and texture(s) of tract
According to the NRCS Onslow County Soil Survey there are 17 different soil series
occurring within the boundaries of the project area as shown in Figures 8-14 and 8-
15 of the Final Engineering and Environmental Assessment Report and as listed in
Table 2 below. Additional information on soil types can be found in Section 8.7.2 of
the Final Engineering and Environmental Assessment Report.

e. Vegetation on tract
The majority of the project area is forested with the exception of a couple of small
agricultural fields on Parcel 12. Forests within the project area can be divided into
the following communities: Pine plantation, mesic mixed hardwood, small depression
ponds, bottomland hardwood and pocosin. A discussion of each of the above
referenced communities and their respective vegetation is provided in Sections
8.7.11 and 8.7.13.2 of the Final Engineering and Environmental Assessment Report.
f. Man-made features now on tract
Man-made features within Parcel 2, 3,11,12, 23 and 62 are limited to unpaved
access roads and drainage ditches with one exception. Parcel 62 contains a
cemetery which was determined as not eligible for the NHRP. The cemetery is
discussed in Sections 8.7.7 and 10.6 of the Final Engineering and Environmental
Assessment Report in greater detail. The location of the cemetery is shown on
Sheet I-7 of the permit drawing set.
The existing LTS contains numerous man made features including the existing
storage and treatment lagoons, the administration building, the equipment storage
building, and numerous auxiliary structures associated with the treatment process.
In addition, the LTS contains several miles of buried transmission mains, irrigation
header and lateral pipes which transport the pretreated effluent to approximately
19,000 sprinkler heads.
The proposed flow equalization tank site contains two existing sanitary sewer lines;
however, there are several man made structures around the site including the main
pump station.
g: What is the CAMA Land Use Plan land classification of the site?
The CAMA Land Use Plan land classification for the effluent storage lagoon site
(Parcels 11 and 12) and the irrigation spray field expansion sites (Parcels 2, 3, 23, 62
and the existing LTS) is rural with services. The flow equalization tank site, which is
in the City of Jacksonville, is zoned as developed.

~ h. How is the tract zoned by local government?
The proposed effluent storage lagoon site, irrigation spray field expansion sites and
the existing LTS are all zoned as residential/agricultural. The proposed flow
equalization tank site is zoned as both townhouses condominiums and apartments,
and industrial.
i. Is the proposed project consistent with the applicable zoning?
The proposed project is consistent with the applicable zoning of the proposed
expansion parcels.
j. Has a professional archaeological assessment been done for the tract?
If Yes, by whom?
Preliminary archaeological research was conducted at the existing LTS site in
conjunction with an EA prepared by Malcolm Pirnie in 1989 for construction of the
existing LTS. This research involved the examination of published studies of coastal
North Carolina, the review of reports on Onslow County archaeology on file at the
North Carolina Department of Archive and History (NCDAH), a walkover and the
excavation and drawing of soil profiles in the floodplain, upland and intermediate
sections of the LTS.
According to the archaeological investigations performed by Gray and Pape (1995),
no known archaeological sites at the time were listed or eligible for listing on the
National Register of Historic Places (NRHP) were known to exist within the existing
LTS. A majority of archaeological sites in the general study area appeared to be
represented by ephemeral prehistoric camps. Sites were generally shallow in nature
and lacking sufficient numbers of features and remains to significantly improve the
understanding of the archaeological past. In addition, many artifacts had been
impacted by tree harvesting and grading activities unrelated to this project.
Inquiries at the inception of this phase of the project determined that no historic
properties were identified on the current resource maps maintained by the State
Historic Preservation Office (SHPO) for the project area. However, the SHPO
requested a Phase I Archeological Survey be conducted for the areas of impact
within the project area, excluding the existing LTS. According to the SHPO, no
impact to archaeological resources are anticipated within these internal expansion
areas.
Phase I surveys were conducted at the proposed effluent storage lagoon sites
between December 2005 and January 2006 by Coastal Carolina Research, Inc.
(CCR). Between April and June 2006, CCR conducted Phase I archaeological
surveys at the proposed irrigation expansion sites, except for within the existing
LTS, and the proposed flow equalization tank site. The archaeological reports for
these surveys and the correspondences with the SHPO are included in the Final
Engineering and Environmental Assessment Report.

k. Is the project located in the National Registered Historic District or does
it involve a National Register listed or eligible property?
The Phase 1 surveys, discussed in Item 4.j above, determined that the project area
does not involve a National Register listed or eligible property.
I. Are there wetlands on the site? Coastal? Other? If yes, has a
delineation been conducted?
Delineations of Waters of the United States (WOOS) were performed within the
piping corridors of the irrigation spray field expansion sites, within the project area
of the flow equalization tank site, and within the effluent storage lagoon expansion
site in entirety. These delineations were conducted in accordance with the 1987 U.
S. Army Corps of Engineers Wetland Delineation Manual (TR Y-87-1)
Wetlands within the project area are predominately forested and scrub-shrub
however, emergent wetlands do occur along maintained utility corridors. Section
8.7.13.2 of the Final Engineering and Environmental Assessment Report
characterizes wetland plants within the project area.
Estimates of the amount of wetlands within the irrigation spray field expansion
areas relied on a detailed soil suitability analysis that was conducted by Nutter and
Associates. Soils deemed suitable for spray irrigation would generally be well
drained, and therefore would not be characterized as hydric soils. Alternatively,
soils determined to be unsuitable for spray irrigation potentially constitute wetland
areas.
Within the proposed irrigation spray field expansion areas, 539 acres of suitable
land not currently under spray irrigation were identified. This information was used
to determine potential piping corridors through and between these potential spray
fields which would minimize impacts to WOUS. During this iterative process,
wetland delineations were conducted to further refine header placement and to
calculate the proposed impacts. Delineations conducted within the header corridors
were verified by the U. S. Army Corps of Engineers Wilmington, NC District Office. A
Jurisdictional Determination was issued for portions of Parcels 2, 3, and 23 on
March 13, 2006. A confirmation site visit was conducted on July 27, 2006 by the U.
S. Army Corps of Engineers for additional areas in Parcels 2, 3, and 23, and within
the proposed header corridors in Parcel 62 and the existing LTS. Although the
Corps concurred with the delineation, a Jurisdictional Determination has not been
issued because of potential regulatory changes associated with the
Rapanos/Carabell Supreme Court decision.
Based on wetland assessments and delineations, and soil suitability analyses,
Parcels 2, 3, 23, 62 and the existing LTS contain approximately 584,124, 90, 82
and 4,009 acres of wetlands, respectively. These totals were calculated by
subtracting the suitable soil and delineated wetland acreages from each parcel's
total acreage, and may represent an overestimate of WOUS. The approximate
locations and extents of WOUS within the irrigation spray field expansion areas are

shown in Figures 8-26 and 8-27 of the Final Engineering and Environmental
Assessment Report and within the permit drawing set.
Delineations of Parcels 11 and 12 were verified by the U. S. Army Corps of Engineers
Wilmington, NC District Office on August 9, 2005 and November 16, 2005
respectively. Parcel 11 contains approximately 75 acres of WOUS, which include
pocosin, bottomland hardwood and 2 doline communities. Parcel 12 contains
approximately 4.2 acres of forested wetlands. One approximate 0.1-acre wetland
system on Parcel 12 was determined by the U. S. Army Corps of Engineers to be an
isolated system. An approximate 600-linear foot intermittent-channelized stream
is located between Parcels 11 and 12. This stream flows to Stewart Branch, which is
the southeastern and southern property border for Parcels 11 and 12, respectively.
The approximate location of WOUS within Parcels 11 and 12 is shown in Figure 8-25
of the Final Engineering and Environmental Assessment Report and within the
permit drawing set.
A delineation was verified and a Jurisdictional Determination was provided by the U.
S. Army Corps of Engineers for the flow equalization tank site on March 13, 2006.
Approximately 1.6 acres of wetlands adjacent to Chaney Creek are located in the 5.3
acre area associated with installation of the flow equalization tank. These wetlands
are forested and emergent wetlands associated with the existing right-of-way
(ROW) and are shown in Figure 8-18 of the Final Engineering and Environmental
Assessment Report and within the permit drawing set.
m. Describing existing wastewater treatment facilities
The LTS is the wastewater treatment facility for the City of Jacksonville, and
therefore treats its own wastewater. A description of the LTS can be found in
Section 1.1 of the Final Engineering and Environmental Assessment Report and in
Item 3.d above.
n. Describe location and type of discharges to waters of the state.
The proposed activities will not discharge to surface waters of the state per 15A
NCAC 02T .0506.
o. Describe existing drinking water supply source.
The 8-inch water line that services the LTS is part of the Onslow County municipal
water supply.

1. EXCAVATION AND FILL
1.a. Amount of material to be excavated from below MHW or NWL in cubic
yards.
No excavation will occur in areas below MHW or NWL as part of the upgrade and
expansion of the City of Jacksonville's Land Treatment System (LTS).
1.b. Type of material to be excavated.
For all project sites, the material to be excavated includes silty sands.
1.c. Does the area to be excavated include coastal wetlands (marsh),
submerged aquatic vegetation (SAVs) or other wetlands?
Delineation of Waters of the United States (WOUS) have been performed on portions
of all of the irrigation spray field expansion sites, the effluent storage lagoon
expansion site, and the flow equalization tank site. The wetlands within these areas
are predominately forested and scrub-shrub, however, emergent wetlands do occur
along maintained utility corridors. The impact of the project on wetlands is further
discussed in Item 4.1 of DCM-MP-1 and within Section 8.7.4 of the Final Engineering
and Environmental Assessment Report.
1.d. Highground excavation in cubic yards.
The amount of highground excavation will approximately be 252,189 cubic yards.
This excavation will be part of the development of the new effluent storage lagoon
on Parcels 11 and 12 and is further discussed in Item 3.a of DCM-MP-1 and within
Section 4.3.2.6 of the Final Engineering and Environmental Assessment Report.
2. DISPOSAL OF EXCAVATED MATERIAL
2.a. Location of disposal area
At the effluent storage lagoon expansion site, the material remaining after
excavation is completed will be used for the construction of the dam surrounding
the lagoon (Figure 8-17, Final Engineering and Environmental Assessment Report).
It is anticipated that no excess material will remain from construction at the effluent
storage lagoon expansion site. Excavation within the irrigation spray field
expansion sites will occur during transmission main and header placement (Figures
8-5 and 8-5A, Final Engineering and Environmental Assessment Report). It is
anticipated that no excess material will remain once the pipelines are in place and
the trenches are backfilled. Excavation at the flow equalization tank site will be
used for the installation of the influent and effluent pipelines which will connect the
flow equalization tank to the existing force main (Figure 8-18, Final Engineering and

~' Environmental Assessment Report). It is anticipated that no excess material will
remain as a result of construction at the flow equalization tank site.
2.b. Dimensions of disposal area.
Once constructed, the 20.2 acre dam, on average, will be 90 feet wide at its base
and will range from 0 to 23 feet above the existing ground surface. The outboard
dam slope will be 2.8:1 and the inboard dam slope will be 2.5:1. The proposed
effluent storage lagoon will be irregularly shaped and will be 74.1-acres in size within
the inner toe of the dam. The disposal area is further discussed in Section 4.3.2.6 of
the Final Engineering and Environmental Assessment Report.
2.c. Do you claim title to the disposal area?
Yes, the City of Jacksonville is the owner of the construction and disposal areas.
2.d. Will a disposal area be available for future maintenance?

There will be 50,808 cubic yards of fill material placed in wetlands during the
construction of the dam around the effluent storage lagoon.
C, 4.a.(2)Dimensions of fill area
As answered above in Item 2.b, the dimension of the fill area would be the same as
the dam bounding the effluent storage lagoon.
4.a.(3)Purpose of fill
The fill material will be used to alter the existing topography of the site to construct
the dam required for the lagoon.
4.b. Will fill material be placed in coastal wetlands (marsh), SAVs or other
wetlands?
Yes, fill material will be placed in non tidal palustrine wetlands during construction
of the dam.
4.b.(1) Dimensions of fill area
The area of fill will be irregularly shaped and will total 4.0 acres in wetlands.
4.b.(2) Purpose of fill
The purpose of the fill will be t9 construct the dam for the effluent lagoon.

5. GENERAL
5.a. How will excavated or fill material be kept on site and erosion
controlled?
All soil disturbances will be conducted pursuant to an Erosion and Sediment Control
Plan approved by the North Carolina Division of Land Resources, Land Quality
Section (Section 8.8.2, Final Engineering and Environmental Assessment Report).
Erosion and sediment controls will be installed and maintained between the
construction site and any nearby down gradient surface waters. Natural vegetated
buffers will be maintained on all streams and creeks adjacent to the work sites.
5.b. What type of construction equipment will be used (for example, dragline,
backhoe, or hydraulic dredge)?
Construction at the site will require the use of various mechanized equipment as
discussed in Item 3.d of DCM-MP-1.
5.c. Will wetlands be crossed in transporting equipment to project site? If
yes, explain steps that will be taken to lessen environmental impacts.
Yes, wetlands will be crossed while transporting equipment to, and within, the
project site. The environmental impacts will be lessened by following the approved
Sediment and Erosion Control Plan, and by minimizing construction activities within,
C or adjacent to, wetlands (Section 8.8.4 Final Engineering and Environmental
Assessment Report).

DCM-MP-3 EXCAVATION AND FILL
~~
a. Type and number of buildings, facilities, units or structures proposed.
The City of Jacksonville Land Treatment System (LTS) upgrade and expansion will
involve the development of a new 95-acre effluent storage lagoon that will be
constructed on City owned property south of the existing effluent storage lagoon.
The lagoon will be contained by a dam which will have a perimeter of approximately
9,000 feet (Item 3.a, DCM-MP-1).
The expansion will involve the construction of a new 2.5 million gallon, flow
equalization tank on city owned property south of the existing main pump station
(Item3.a, DCM-MP-1). The tank will be constructed to contain wastewater during
peak flow events at the pump station. Wastewater will enter the tank after passing
through a new vault and mechanical screen with a bypass channel. The mechanical
screen will be housed in a building which will be constructed north of the proposed
flow equalization tank. Once the flow of wastewater into the pump station has
decreased below 18.0 MGD, the stored wastewater will be released back to the pump
station through an existing gravity sewer.
As part of the expansion, a third treatment train parallel to the existing Train Nos.1
and 2 will be constructed and it will include four separate cells (Item 3.a, DCM-MP-1).
Cell A will have a top of berm dimension of 290 ft x 290 ft and a volume of 4.5
million gallons. Cells B-D will have a top of berm dimension of 290 ft x 520 ft and a
combined volume of 9.0 million gallons. Effluent flow will be distributed to the West
and South storage lagoons by a newly constructed aerated lagoon effluent splitter
box which will be sited west of the new Train 3.
The spay field irrigation system will be expanded to increase the capacity of the
system to accept the pretreated wastewater being held within the effluent storage
lagoons (Item 3.a, DCM-MP-1). The wastewater will be supplied to the expansion
areas in Parcels 2, 3, and 23 through a new transmission main and header pipelines
having a total length of approximately 6.7 miles. The improvement and extension of
existing header pipelines will allow for the irrigation of suitable lands within Parcel
62 and the existing LTS.
b. Number of lots or parcels.
The land treatment system upgrade and expansion will involve the use of eight
parcels which are owned by the City of Jacksonville, NC (Item 2.c, DCM-MP-1).
c. Density (give the number of residential units and the units per acre)
N/A
d. Size of area to be graded, filled or disturbed including roads, ditches, etc.
The total area of land disturbance will be approximately 238 acres. The flow
equalization tank will require clearing of 0.1 acres, the storage lagoon will require 117
acres of mixed forest and 8.0 acres of ag land cleared, the irrigation expansion will

f require 108 acres of pine forest cleared for piping and irrigation, and the
pretreatment facilities will require 5 acres of disturbance (Section 8.8.11, Final
Engineering and Environmental Assessment Report).
e. If the proposed project will disturb more than one acre of land, the
Division of Land Resources must receive an erosion and sedimentation control
plan at least 30 days before land disturbing activities begin. If applicable, has a
sedimentation and erosion control plan been submitted to the Division of Land
Resources?
No, an erosion and sediment control plan has not been submitted. However, an
erosion and sediment control plan will be submitted to, and approved by, the
Division of Land Resources prior to soil disturbance at the Project Site (Section
8.8.2, Final Engineering and Environmental Assessment Report).
f. List the materials (such as marl, paver stone, asphalt, or concrete) to be
used for paved surfaces.
N/A
g. Give the percentage of the tract within 75 feet of MHW or NWL, or within
575 feet in the case of an Outstanding Resource Water, to be covered by
impervious and/or built-upon surfaces, such as pavement, buildings, rooftops,
or to be used for vehicular driveways or parking.
No portion of the project area within 75 feet of MHW or NWL, or within 575 feet of
an Outstanding Resource Water, is to be covered by an impervious and/or built-upon
surface, or to be used for vehicular driveways or parking.
h. Projects that require a CAMA Major Development Permit may also
require a Stormwater Certification. Has a site development plan been
submitted to the Division of Environmental Management for review?
No, a site development plan has not been submitted. However, a site development
plan will be submitted to, and approved by, the Division of Environmental
Management prior to development at the site.
i. Describe proposed method of sewage disposal.
Sewage produced at the site will be treated by the City of Jacksonville's Land
