The project site is located within an undeveloped, forested area adjacent to existing utility easements held by the City of Durham and Duke Power. The southernmost portion of the
project site consists of herbaceous, meadow -like community along the adjacent utility corridors. The herbaceous cover is retained by infrequent, regular site maintenance. The project
site is located within a 5.8-acre utility easement acquired from Durham Technical Community College. The site abuts a Durham Technical Community College facility and associated
parking areas to the north, Snow Hill Road to the west, an existing wastewater pump station access road and overhead electric lines to the south, and undeveloped forested lands to the
east.

4f. List the total estimated acreage of all existing wetlands on the property:
0.13
4g. List the total estimated linear feet of all existing streams on the property:
4h. Explain the purpose of the proposed project:*
Currently, there are three pump stations that send flow to the existing pump station on Snow Hill Road. The three upstream pump stations have a combined capacity of 3,540 gallons
per minute (gpm). The existing pump station capacity is 1,190 gpm and is therefore a limiting factor in accommodating high flows or increased flows. The proposed pump station will
have a capacity of approximately 4,800 gpm, allowing the proposed pump station to efficiently convey peak flows from the three upstream pump stations. Additionally, the existing pump
station and the majority of the length of the access road are situated in the mapped 100-year flood zone (future condition). In order to comply with the 2T rules, the proposed pump
station and associated infrastructure will be constructed outside the 100-year flood zone (future condition). The pump station, chemical tank, and odor control facility will have finished
floor elevations approximately 5 feet above the BFE, and the electrical generator pad will have an elevation approximately 6 feet above the BFE.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The project consists of construction of a new4,800-gpm wastewater pump station and associated infrastructure. Associated infrastructure for the Snow Hill Road Pump Station (SHRPS)
project includes electric generator, odor control facility, chemical tank, a retaining wall, and paved access driveway. The driveway will connect to Snow Hill Road immediately north of the
existing utility access road. A culvert will be installed under the new access road to allow roadside stormwater drainage to continue to be conveyed along the east side of Snow Hill
Road. The new SHRPS will tie into the existing sewer network and allow the existing SHRPS to be decommissioned. An existing stormwater pipe discharges onto the land which is
proposed to be paved for the access driveway. As such, the pipe will be realigned, and a new discharge will be established downgradient of the proposed access driveway.
The project is anticipated to result in permanent impacts to a jurisdictional wetland in order to accommodate construction of the proposed access driveway above the 100-year flood
zone, future condition, as required under 2T rules. Trees will be removed from within the site to accommodate the access road, pump station, and construction staging/temporary
stockpile area. The trees to be removed consist of a narrow swath of early successional forest along the proposed access road corridor and two rectangular areas to accommodate the
pump station and staging/stockpile area. Erosion and sediment control devices will be in place prior to initiation of land disturbance or tree removal. The devices include perimeter silt
fence, clean water diversion, outlet protection, concrete washout area, dewratering silt bag filtration, and a stabilized construction entrance. Additionally, minimization of tree removal was
factored into the site design.
Construction -phase access to the project site will be provided via the existing pump station access road. A gravel construction entrance will be installed between the existing access
road and the site. The existing road is located within the existing ingress/egress easement held by Duke Power. Staging of equipment or materials within the ingress/egress easement is
not permitted as doing so may impede access and response time in case of an emergency.
Equipment to be used for the proposed project may include, but is not limited to, an excavator, backhoe, front-end loader, bulldozer, crane, and dump trucks. Blast mats will be utilized
during blasting operations, as required under North Carolina OSHA standards.
4j. Please upload project drawings for the proposed project.

E. Impact Justification and Mitigation u
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The design team evaluated the pump station site for potentially jurisdictional waters in areas assessed for siting the pump station structure. Full
avoidance of all regulated and sensitive resources is only possible with a No Action alternative, which leaves the epsting pump station at risk of
damage due to flooding, at risk of being inaccessible due to flooding of the access road, and as the capacity -limiting component of the sewershed.
The design team evaluated several design concepts for engineering feasibility, site layout, system connectivity, and avoidance of sensitive resources.
The selected alternative (1) avoids impacting the 100-year flood zone, streams, and protected riparian buffers; (2) places utility lines in upland areas;
(3) meets the need for the project; and (4) provides a logical site layout.
The pump station and associated structures have been laid out in upland areas and above the 100-year base flood elevation, in accordance with the
2T rules. The site layout allows for excavation activities to avoid encroaching on the wetland. Full avoidance of the wetland would (1) require removal
of trees from an area that is not anticipated to otherwise be impacted by the project and that is within the 100-year flood zone (future condition), (2)
require laydown of materials and staging of equipment in the Duke Power overhead electric or ingress/egress easement that abuts the site to the
south, and/or (3) construction of the proposed access road in the 100-year flood zone (future condition), which does not fully meet the purpose and
need of the project. Construction of the proposed access road outside the wetland area would not provide access to the pump station following
significant storm events and would not comply with the 2T rules.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Best management practices for erosion and sediment control measures are specified in the project design. Measures include perimeter silt fence,
clean water diversion, outlet protection, concrete washout area, dewatering silt bag filtration, and a stabilized construction entrance. Additionally,
minimization of tree removal was factored into the site design. The contractor shall perform weekly inspections of erosion and sediment control devices
and perform maintenance as needed to ensure mabmum efficacy of all devices in use. Vehicle and equipment maintenance activities are required to
be performed outside of jurisdictional areas. Disturbed soils will be temporarily stabilized if the disturbed area will not be final graded and permanently
stabilized within a reasonable timeframe.

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?

Snow Hill Road Pump Station — Phase 1
Detailed Information for Proposed Blasting Operations
The proposed Snow Hill Road Pump Station is required to be approximately 40 feet deep, connecting to
existing and proposed sanitary sewer lines. According to boring logs and a geotechnical report of the
pump station area, approximately 25 feet of partially weathered rock underlays the soil within the
project site. Therefore, in order to complete excavation in the area, blasting will be required. Blasting
shall be performed according to standard specification 3123 16 — Excavation By Blasting, North Carolina
Occupational Safety and Health Administration (OSHA) standards, and recommendations of the
Geotechnical Report.
Explosives shall be of such quantity and power and shall be used in such locations as will neither open
seams nor otherwise disturb the material outside the prescribed limits of excavation. As the excavation
approaches its final limits, the depth of holes for blasting and the amount of explosives used for each
hole shall be reduced so that the underlying or adjacent rock will not be disturbed or shattered.
A pre -construction survey, condition inspection and documentation of adjacent structures on -site and
off -site shall be performed by the Contractor. The Contractor shall notify each adjoining property owner
within 2,500 feet of the site of the anticipated ground vibrations and noise which will occur due to
blasting operations. Notice shall be given 30 days in advance to enable adjacent property owners to take
precautions they consider necessary. The Contractor shall limit blasting operations to minimize
disturbance to adjacent property owners. Motorists on adjacent roadways shall be notified in
accordance with state regulations. Adequate signage to alert motorists to blasting operations shall be
provided in accordance with requirements of the North Carolina Department of Transportation.
For each blast round, Contractor shall monitor and record noise and air blast overpressures at the site
perimeter nearest the blast location and at the on -site or off -site structure located nearest to the round.
The site of every blast round shall be sufficiently covered with blasting mats or other devices to prevent
any flying debris. Whenever blasting is to be performed within 2,500 feet of a structure, the Contractor
shall measure the peak particle velocities of ground vibration resulting from each blast at the structure
to ensure that no damage occurs to adjacent structures.

WaC 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 fo
office(s) with jurisdiction in the defined project area. Please read the introduction to eac
follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for a

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 of the U.S. Fish and Wildlife
Service (USFS) 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

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.

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 (1)
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, O
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 and/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?
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
https:Hecos.fws.gov/ipac/location/RZN3NI243FGZVJQP5QBICOBLRU/resources 2/11/2020

INC: Explore Location Page 10 of 12
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
Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use th
migration. Models relying on survey data may not include this information. For additional
tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel
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 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 1 1 ly N-3 Ir'll
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.
This location overlaps the following wetlands:
FRESHWATER FORESTED/SHRUB WETLAND
PF01A
A full description for each wetland code can be found at the National Wetlands Inventory website
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.
