4h. Explain the purpose of the proposed project:*
The existing force main is a 12-inch diameter pipe that conveys wastewater from the existing Snow Hill Road Pump Station to a 21-inch diameter gravity sewer, which carries the
wastewater to the Eno River Pump Station. The Snow Hill Road Pump Station is being replaced under a separate project (SAW-2020-00987 and DWR #20-0727), and the existing 12-
inch force main does not have the capacity to hydraulically accommodate future peak flow rates from the new Snow Hill Road Pump Station. The proposed 20-inch Snow Hill Road Force
Main will convey flows to a proposed new segment of gravity sewer at the Eno River Pump Station. The new segment of gravity sewer will replace the downstream most segment of the
existing, 21-inch influent sewer and will tie into the existing 48-inch influent gravity sewer.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The project consists of installation of approximately 14,423 feet of 20-inch sewer force main and 120 feet of 48-inch gravity sewer. The force main and gravity sewer will be ductile iron
pipe. The force main pipe will extend from an existing fitting in the sewer collection network located at 2525 Snow Hill Road to a new manhole (MH-1) adjacent to the Eno River Pump
Station. The proposed force main will parallel the existing force main, which will be abandoned once the proposed pipe is put into service. The pipe corridor parallels the west side of the
right-of-way associated with Snow Hill Road, heading south to just southeast of the eastern terminus of Infinity Road. The pipe corridor then turns to the southwest, following the existing
utility easement toward the Eno River. The proposed pipe will cross the Eno River, traverse an undeveloped island, and cross an oxbowconnected to the Eno River. The river, island,
and oxbow crossings Will be installed via a trenchless technique, specifically horizontal directional drilling. The pipe corridor follows the existing sewer easement to the west, then north-
northwest, then west to MH-1 adjacent to the Eno River Pump Station. The gravity sewer will begin at manhole MH-1 and extend to an existing manhole (MH-4) that is proposed to be
replaced. From MH-4, the existing gravity sewer Will convey the wastewater into the Eno River Pump Station.
From MH-1 to the end of the existing 21-inch diameter gravity sewer, the existing gravity line will be removed. The proposed 48-inch gravity sewer, extending from MH-1 to MH-4, Will
provide conveyance of flows currently carried by the gravity sewer segment to be demolished. To accomplish the connections and turns required along the 48-inch gravity line, a total of
four manholes Will be installed.
The pipe will be installed via open cut trench for the majority of its length. The crossing of Infinity Road Will be installed by jack and bore. Horizontal directional drilling will be the method
of installation under the Eno River and an oxbow of the Eno River. The pipe Will also be horizontally directionally drilled across the island located between the Eno River and its oxbow.
The proposed sewer pipe crosses eight streams, including Cabin Branch, the Eno River, the Eno River oxbow, an unnamed tributary (UT) to the Eno River, two UTs to Little River, and
two UTs to Cabin Branch. Temporary impacts to six of the streams are proposed to result from the open -cut installation of the new force main. The stream crossings will be performed
under dry conditions, using a cofferdam and temporary pump -around system to establish and maintain the dry work area. Once the streambed and banks are restored to their pre -
construction grade and elevation and stabilized, the temporary pump -around system and cofferdams will be removed, allowing the stream flowto return to its natural course. The pipe
corridor is in proximity to two jurisdictional wetland areas and one pond. The wetlands and the pond Will not be impacted by construction of the proposed project.
A variety of construction equipment is anticipated to be used due to the various construction techniques for the project. A horizontal directional drill rig and associated equipment,
reamers, HOPE pipe rollers, cranes, jack and bore machine, backhoes, trackhoes, excavators, shoring equipment, land clearing equipment, and welders are expected to be used.
Additionally, grout pumps, temporary stream bypass pumps, generators, and dump trucks are expected to be utilized. Other construction equipment may be utilized at the discretion of
the contractor.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
2.5MB
2.49MB
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
u

Impacts to jurisdictional areas can only be fully avoided by a no -build alternative, which does not meet the purpose and need for the project. Extensive
efforts to minimize impacts to jurisdictional areas have been made during the development of the project design. The proposed force main follows an
existing force main parallel to an existing NCDOT road and in both existing and proposed easement. Designing the pipe along an already maintained
corridor minimizes new impacts to streams as they are already being maintained. In locations where new easement is required due to space limitations
inside the existing easement, the new force main is designed to be installed as close to the existing easement as possible in order to minimize the new
easement width.
Wetland and open water impacts have been fully avoided by modifications to the alignment and the width of disturbance in areas near these features.
The limits of disturbance have been reduced in width within streams and riparian buffer areas. Permanently maintained corridors will be retained in
perpetuity to accommodate future operations and maintenance needs and provide access for emergency response. Where feasible, the maintained
corridor for the proposed force main will coincide with currently maintained corridors. The proposed new maintained corridors have been reduced in
width within stream buffer areas. The maintained corridors will be seeded with native grasses. The portions of the construction corridor that are
beyond the maintained corridor will be allowed to revegetate naturally from local seed stock.
Relocating the pipe to the east side of Snow Hill Road may offer an opportunity to further reduce the impacts to UT1 to Cabin Branch. However, this
alignment modification was eliminated from consideration due to the presence of an existing natural gas pipeline parallel to the east side of Snow Hill
Road in this area. The measures necessary to avoid conflicts with the natural gas pipeline would result in significantly greater private property
impacts, tree removals, and risks during construction.
Crossings of streams and riparian buffer areas have been designed to be within 15 degrees of perpendicular to the extent practicable. One stream
crossing (S3 — UT2 to Cabin Branch) is not practicable to be achieved at a near -perpendicular angle. Crossing Lfr2 to Cabin Branch at a near -
perpendicular angle would necessitate disturbance of approximately 3,275 square feet of forested buffer that will not be disturbed as a result of the
proposed design. The design keeps the buffer disturbance almost entirely in areas that are currently maintained as part of the roadway right-of-way,
overhead electric easement, and buried utility easement. The impacts to the buffer associated with the UT2 to Cabin Branch crossing will consist of
temporary disturbance of maintained grassy areas that will be restored to pre -construction conditions upon installation of the force main.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
The erosion and sediment control measures specified in the design will be installed prior to initiation of land disturbance. Regular inspections of the
erosion and sediment control devices Will be performed, and any necessary repairs or modifications to the devices will be addressed in a timely
manner to ensure that they are maintained in good working order throughout the construction period. Erosion and sediment control devices shall
include silt fencing, fiber filtration tubes and channel lining for drainage swales and roadside ditches, stabilized construction entrances, and temporary
stabilization of disturbed soils and sediments. Excavations will be backfilled and restored on a daily basis to protect against erosion of disturbed soils.
Installation methods were evaluated for each stream crossing associated with the proposed design. Where practicable, trenchless techniques wall be
utilized to avoid impacts to streams and buffers. Horizontal directional drilling Will be performed for the Eno River and Eno River oxbow installation.
Trenchless techniques were determined to be infeasible options at the remaining six stream and buffer crossings.
In -stream construction Will be performed in the dry. Temporary cofferdams and pump -around system will be utilized to establish and maintain dry
conditions within the work area. Stream water discharged from the pump will pass through a filter bag or other device intended to remove excess
sediments from the water prior to returning to the stream channel downstream of the work area.
Construction support activities Will be performed away from surface waters, riparian buffers, and other sensitive resources. Vehicle and equipment
maintenance Will be performed in upland areas to protect against unintentional spills or leaks reaching sensitive ecological areas. Staging of
equipment and materials will be sited in upland areas along the project construction corridor.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes
r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:

5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat?
The IPaC tool was utilized to identify the federally protected species that may occur in the project vicinity. IPaC identified three species proposed for
listing, three endangered species, and two proposed critical habitat areas. The endangered species include dwarf wedgemussel (DWM), Michaux's
sumac, and smooth coneflower. DWM's inclusion on the list is associated with the Eno River. The Eno River and its oxbow will be traversed via
trenchless technique, thereby avoiding impacts to the waterways, their habitats, and water quality in the waterways. Michaux(s sumac and smooth
coneflower inhabit disturbed areas and edges of forested areas that occur on circumneutral to basic soils. The soils required for the endangered
plants are not mapped within the project area. Hazen biologists performed visual assessments of the project area during onsite investigations in June
2020 and observed no individuals of the two species.
Designated critical habitat has been proposed for two species that are proposed for listing - Carolina madtom and %use River waterdog. The
proposed critical habitat for Carolina madtom and for Meuse River waterdog within the project area is within the Eno River, which will be crossed by a
trenchless technique and thereby not impacted by the proposed project.

Re Project: Snow Hill Road Force Main

This document confirms that Durham County (Applicant) for the Snow Hill Road Force Main (Project)
has expressed an interest to utilize 15,609.00 Square Feet of Riparian Buffer Mitigation Credits from
the EBX sponsored Upper Neuse Riparian Buffer Umbrella Mitigation Bank or EBX-Neuse I, LLC
sponsored Bucher Mitigation Bank. The specific bank site to be debited will either be Cedar Grove,
Hatley or Bucher all located in HUC 03020201 and in the Falls Lake watershed. As the official Bank
Sponsor, EBX and EBX-Neuse I, LLC, attests to the fact that mitigation is available for reservation at this
time.
These mitigation credits are not considered secured, and consequently are eligible to be used for alternate
purposes by the Bank Sponsor, until payment in full is received from the Applicant resulting in the
issuance of a Mitigation Credit Transfer Certificate by the bank acknowledging that the Applicant has
fully secured credits from the bank and the Banker has accepted full responsibility for the mitigation

Snow Hill Road Force Main – diffuse flow discussion
Diffuse flow will be maintained throughout the limits of disturbance and the riparian buffer through the
use of permanent seeding and planting of native and riparian vegetation, and maintenance of existing
drainage patterns throughout the buffered areas. No grading or permanent stormwater measures will
be put in place to channelize or concentrate stormwater runoff from the site. The erosion and sediment
control measures for the project were designed to meet NC DEQ requirements, including the NC Erosion
and Sedimentation Control Planning and Design Manual and the NC Construction General Permit
NCG01, as well as Title 15A, Chapter 4 of the NC Administrative Code. The proposed project will not
create concentrated stormwater flow through the buffer.
Description of Blasting
Blasting is necessary to fracture the subsurface rock so that it can be excavated by mechanical means
when the pipe laying construction equipment digs the pipe trench. It is confined to the pipe alignment,
and blasts are sized and spaced to provide the necessary fracturing while maintaining the fracturing
within the work area limits. Generally, a drill rig works ahead of the trench excavation equipment (pipe
laying crew), and drills pilot holes until the surface of the rock is located. Then, the rig will drill holes to
the depth required through the rock to set the dynamite in the proper location. Typically, the pilot hole
drilling is completed for a certain length ahead of the pipe laying crew to map out the rock profile. The
drilling and blasting crew returns to drill and set the dynamite. The pre-blast effort can take days or
weeks depending on how far ahead of the pipe laying the contractor wants to drill before blasting.
Blasting is typically performedin an isolated section where blast mats can be laid on top of the ground
surface above the blasting area. Setup for blasting may take several days, and a series of blasts in one
location will be performed in one day. The blast locations are dictated by the actual subsurface
conditions discovered during pre-drilling of the pipe alignment.
IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat
(collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS)
jurisdiction that are known or expected to be on or near the project area referenced below. The list
may also include trust resources that occur outside of the project area, but that could potentially be
directly or indirectly affected by activities in the project area. However, determining the likelihood and
extent of effects a project may have on trust resources typically requires gathering additional site-
specific (e.g., vegetation/species surveys) and project-specific (e.g., magnitude and timing of proposed
activities) information.
Below is a summary of the project information you provided and contact information for the USFWS
office(s) with jurisdiction in the defined project area. Please read the introduction to each section that
follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional
information applicable to the trust resources addressed in that section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of project
level impacts.
The primary information used to generate this list is the known or expected range of each species.
Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the
species range if the species could be indirectly affected by activities in that area (e.g., placing a dam
upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the
species by reducing or eliminating water flow downstream). Because species can move, and site
conditions can change, the species on this list are not guaranteed to be found on or near the project
area. To fully determine any potential effects to species, additional site-specific and project-specific
information is often required.
Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary
information whether any species which is listed or proposed to be listed may be present in the area of
such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal
agency. A letter from the local office and a species list which fulfills this requirement can only be
obtained by requesting an official species list from either the Regulatory Review section in IPaC (see
directions below) or from the local field office directly.
For project evaluations that require USFWS concurrence/review, please return to the IPaC website and
request an official species list by doing the following:
1. Draw the project location and click CONTINUE.
2. Click DEFINE PROJECT.
3. Log in (if directed to do so).
4. Provide a name and description for your project.
5. Click REQUEST SPECIES LIST.
Listed species
and their critical habitats are managed by the Ecological Services Program of the U.S. Fish and Wildlife
Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric Administration
(NOAA Fisheries ).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list.
Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows
species that are candidates, or proposed, for listing. See the listing status page for more
information. IPaC only shows species that are regulated by USFWS (see FAQ).

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project activities
to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper
Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this
report.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your
project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A
taller bar indicates a higher probability of species presence. The survey effort (see below) can be used
to establish a level of confidence in the presence score. One can have higher confidence in the
presence score if the corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in the week
where the species was detected divided by the total number of survey events for that week. For
example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of
them, the probability of presence of the Spotted Towhee in week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of presence is
calculated. This is the probability of presence divided by the maximum probability of presence
across all weeks. For example, imagine the probability of presence in week 20 for the Spotted
Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week
of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is
0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of
presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season ( )
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its
entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.
Survey Effort ( )
Rusty Blackbird Euphagus carolinus
This is a Bird of Conservation Concern (BCC) throughout its range in the
continental USA and Alaska.
Breeds elsewhere
Wood Thrush Hylocichla mustelina
This is a Bird of Conservation Concern (BCC) throughout its range in the
continental USA and Alaska.

1/19/2021https://ecos.fws.gov/ipac/location/3TCSQCBFF5BFRHPXGLUBLEUIAU/resources
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is
expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ( )
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on all
years of available data, since data in these areas is currently much more sparse.
Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any
location year round. Implementation of these measures is particularly important when birds are most likely to occur in
the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding
their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be
breeding in your project area, view the Probability of Presence Summary.Additional measures or permits may be
advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present
on your project site.
What does IPaC use to generate the migratory birds potentially occurring in my specified location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC)and other species that
may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network
(AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried
and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects,
and that have been identified as warranting special attention because they are a BCC species in that area, an eagle
(Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or
development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not
representative of all birds that may occur in your project area. To get a list of all birds potentially present in your
project area, please visit the AKN Phenology Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in
my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian
Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science
datasets .
Probability of presence data is continuously being updated as new and better information becomes available. To learn
more about how the probability of presence graphs are produced and how to interpret them, go the Probability of
Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering, migrating or present year-round in my project area?
Page 8 of 11IPaC: Explore Location resources
1/19/2021https://ecos.fws.gov/ipac/location/3TCSQCBFF5BFRHPXGLUBLEUIAU/resources
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-
round), you may refer to the following resources:The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you
are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird
on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area,
there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the
bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range
anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the
continental USA; and
3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of
the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain
types of development or activities (e.g. offshore energy development or longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid
and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more
information on conservation measures you can implement to help avoid and minimize migratory bird impacts and
requirements for eagles, please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and groups of bird
species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also
offers data and information about other taxa besides birds that may be helpful to you in your project review.
Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS
Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including
migration. Models relying on survey data may not include this information. For additional information on marine bird
tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle
Act should such impacts occur.
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern.
To learn more about how your list is generated, and see options for identifying what other birds may be in your project
area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified
location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that
overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey
effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high
survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as
more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of
certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of
concern have the potential to be in your project area, when they might be there, and if they might be breeding (which

means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in
knowing when to implement conservation measures to avoid or minimize potential impacts from your project
activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about
conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your
migratory bird trust resources page.

Wetlands in the National Wetlands Inventory
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of
the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers
District.
Please note that the NWI data being shown may be out of date. We are currently working to update our
NWI data set. We recommend you verify these results with a site visit to determine the actual extent of
wetlands on site.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information
on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery.
Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use
of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland
boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the
amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata
should be consulted to determine the date of the source imagery used and any mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be
occasional differences in polygon boundaries or classifications between the information depicted on the map and the
actual conditions on site.
Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery
as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic
vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some
deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These
habitats, because of their depth, go undetected by aerial imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a
different manner than that used in this inventory. There is no attempt, in either the design or products of this
inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the
geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities
involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or
local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such
activities.

The project consists of construction of a new sewer force main, connecting
the new Snow Hill Road Pump Station (currently under construction) to the
existing Eno River Pump Station. The proposed force main extends
approximately 2.78 miles. The proposed project generally follows either
existing sewer easements or roadway rights-of-way. A stream determination
for buffer applicability was conducted on 9/10/2020 for the project.
Installation of the proposed force main will be by open cut trenching for the
majority of the length. Trenchless installation techniques will be used to
install the crossing of the Eno River (mainstem and an oxbow).
Ple ase attach the docume ntation you would like to hav e the me e ting about.
