Action ID No. SAW-2022- 01017
To Julia Tillery,
On behalf of the City of Durham (City), CDM Smith Inc. (CDM Smith) is pleased to submit this pre -
construction notification (PCN) and supplemental information concerning the Stagecoach Road
Force Main Sewer Improvements project in Durham County, North Carolina (Figure 1). We are
requesting concurrence from the U.S. Army Corps of Engineers (USACE) that the activities proposed
below may proceed under a Nationwide Permit 58 and concurrence from the NC Division of Water
Resources (NCDWR) that the activities proposed below may proceed under an Individual Water
Quality Certification. We are also requesting a riparian buffer authorization in the Jordan Lake
Watershed. A NCDWR pre -filing meeting request was submitted on June 16th, 2023 (submittal e-
mail attached).
Project Purpose and Need
Durham is one of the most rapidly growing cities in North Carolina. Significant development in the
Stagecoach Basin has resulted in increased wastewater flow to the Stagecoach Lift Station (LS) and
Southpoint LS (Figure 2). The purpose of the project is to improve the infrastructure to manage the
additional flow and continue to provide wastewater treatment for the City's residents.

Project Description
The Stagecoach Road Force Main Project will redirect wastewater flow to the South Durham Water
Reclamation Facility (SDWRF). The Stagecoach LS and Southpoint LS will both send wastewater
through new force mains to the SDWRF.
The Stagecoach Road Force Main Sewer Improvements project includes the following components:
■ Installation of approximately 8,645 linear feet of 24-inch force main between the Stagecoach
Road LS and the SDWRF.
■ Installation of approximately 3,275 linear feet of 8-inch force main between the Southpoint
Plantation LS and the SDWRF.
■ Temporary facilities (including bypass pumping and temporary water) as required to
maintain service during construction and connection to the new facilities.
■ Grading, paving, erosion control, site cleanup, seeding, and testing of all installed sewer
infrastructure.
There are approximately 11.3 acres of ground disturbance planned. Construction for the force
mains installation will include work along a new 30-foot wide sewer right-of-way, and existing
sewer and NCDOT right-of-way. More details regarding the proposed work are shown on the
impact plan sheets.
The construction period is estimated to be approximately 18 months, with temporary wetland,
stream and buffer impacts in place for less than 90 days each. Each individual temporary impact
would be limited to a very short time, just enough to install or replace the gravity sewer lines.
Standard construction and pipe installation equipment such as cranes, excavators, dump trucks,
and similar vehicles would be used for the project. Proper erosion and sedimentation control
measures would be employed throughout the project.
Jurisdictional Features
Mr. Jason Hales of CDM Smith conducted a wetland delineation within the approximately 76-acre
Project Study Area (PSA) on June 161h and 17th, and September 2nd, 2021. Figures 3 through 6 show
the USGS topographic, USDA Soils survey, NWI wetland, and preliminary wetland boundary
mapping for the site. Seven wetland areas, three perennial streams, and three intermittent streams
were identified during the delineation (Figure 6). Table 1 provides a summary of the delineated
features within the PSA. A preliminary jurisdictional determination (PJD) request for the
delineation was submitted to the USACE on May 4th, 2022. A PJD concurrence e-mail verifying the
delineation was received from the USACE on July 7th, 2022 (attached). A buffer determination
request for the project area was submitted to NCDWR on March 20th, 2023 and a buffer
determination letter was received from NCDWR on April 181h, 2023 (attached).

Proposed Impacts
Permanent and temporary impacts to wetlands, streams and buffers would be necessary to
improve the sewer infrastructure. The proposed wetland, stream and buffer impacts are described
below, summarized in Tables 2, 3 and 4 below, and shown on the attached impacts plan sheets.
Wetland Impacts
There are 0.975 acres of proposed permanent wetlands impacts for land clearing, conversion, and
force main installation along a new maintained 30-foot wide sewer right-of-way between the
Stagecoach LS and the SDWRF. (Impacts plan sheet C-102, C-103, C-104, C-105, C-106, C-107 and C-
108), Impact numbers W1, W2, W3 and W5). These areas will be cleared of vegetation, used for the
installation of the 24-inch force main, and maintained for future access.
There are a total of 0.975 acres of proposed permanent wetland impacts.
There are 1.109 acres of proposed temporary wetlands impacts for construction access and force
main installation between the Stagecoach LS and the SDWRF. (Impacts plan sheets C-104, C-105, C-
106, C-107 and C-108, Impact numbers W4 and W6). These areas will be used for the installation of
the 24-inch force main and maintained for future access.
There are a total of 1.109 acres of proposed temporary wetland impacts.
There are a total of 2.084 acres of proposed permanent and temporary wetland impacts.

In wetland areas used for the force main installation the material from the trench will be used to
back fill and will be returned to the trench after the force main installation. Impacted wetland areas
will be seeded with native wetland herbaceous species and then be maintained as herbaceous
wetlands for future access.

Stream Impacts
There are 67-linear feet of proposed temporary stream impacts for dewatering and force main
installation across New Hope Creek between the Stagecoach LS and the SDWRF (Impacts plan sheet
C-104, Impact number S1). This area will be used for the installation of the 24-inch force main. The
proposed construction corridor across the stream is 40-foot wide with a planned 30-foot wide
permanent maintained right-of-way.
There are a total of 67-linear feet of proposed temporary stream impacts.
The stream bed in areas of proposed temporary stream impacts will be restored to pre -project
elevations and widths using natural stream bed material. Temporarily impacted stream banks will
be restored through regrading, seeding and woven coir fiber mat, and then be maintained for future
access. All work in or adjacent to streams will be conducted so that the flowing stream does not
come in contact with the disturbed area (typical detail shown on sheet CD-8).

Avoidance and Minimization
The proposed wetland, stream and buffer impacts have been kept to the minimum possible to allow
the sewer infrastructure installation. The planned limits of disturbance for construction and
permanent maintenance corridors were reduced following the wetland delineation to reduce
potential impacts. The proposed impact amounts would be a maximum of potential impacts to the
features. Land clearing will be the minimum necessary to install the infrastructure.
In wetlands, across stream channels and in riparian buffers, stumps will be grubbed only as needed
to install the infrastructure, and remaining stumps will be cut off at grade level. The general
stripping of topsoil within wetlands along the construction corridor will be avoided. Heavy
equipment working in wetlands will be placed on mats to minimize soil disturbance and
compaction. Work in wetlands will be limited to only what is necessary to install the infrastructure.
Impacted wetland areas will be seeded with native wetland herbaceous species and then be
maintained as herbaceous wetlands for future access.
All work in or adjacent to streams will be conducted so that the flowing stream does not come in
contact with the disturbed area (typical detail shown on sheet CD-8). Temporarily impacted stream
banks will be restored through regrading, seeding and woven coir fiber mat, and then be
maintained for future access. The stream bed in areas of proposed temporary stream impacts will
be restored to pre -project elevations and widths using natural stream bed material.
There will be no change in pre -construction contours of waters of the United States in temporarily
impacted areas. Erosion control matting that incorporates plastic mesh and/or plastic twine will
not be used along stream banks or within wetlands. All mechanized equipment operated near

Page 7
surface waters shall be inspected and maintained regularly to prevent contamination of surface
waters from fuels, lubricants, hydraulic fluids, or other toxic materials. Construction shall be staged
in order to minimize the exposure of equipment to surface waters to the maximum extent
practicable.
Mitigation
Mitigation is proposed for 0.975 acres of wetland conversion associated with the planned new
maintained 30-foot wide sewer right-of-way between the Stagecoach LS and the SDWRF. Wetland
credits would be purchased from a private bank in the Cape Fear 03030002 River Basin. A
Statement of Availability was received from Wildlands Holdings VI, LLC on August 281h, 2023
(attached) for 1.00 acres of wetland mitigation credits from the Cape Fear 02 Umbrella Mitigation
Bank: Flat Rock Mitigation Site.
Threatened and Endangered Species
A biological assessment for potential effects to endangered or threatened species was submitted to
the US Fish and Wildlife Service (USFWS) Raleigh office for review on February 281h, 2023
(attached). The biological assessment included a field reconnaissance survey for potential
threatened and endangered species and habitats conducted in the project area June 161h and
September 2nd, 2021. As of the date of this request a response has not been received from the
USFWS. The biological assessment recommended that the proposed action is not likely to adversely
affect any federally listed endangered or threatened species, their formally designated critical
habitat, or species currently proposed for listing at these sites.
Historical and Cultural Resources
An environmental review request for the project was submitted on February 27th, 2023 to the
North Carolina State Historic Preservation Office (NC HPO). A response was received on May 22nd,
2023 from NC HPO following their review of the project. They are aware of no historic resources
which would be affected by the proposed project (response e-mail attached).
We look forward to working with you on the project. Please contact us with questions or if
additional information is required.
Sincerely,
690--944

Dear Jason Hales,
Reference is made to Corps Action ID: SAW-2022-01017. Please reference this number on any correspondence regarding
this action.
We have reviewed the information provided by you concerning the aquatic resources, and by copy of this e-mail, are
confirming that the aquatic resources delineation has been verified by the Corps to be a sufficiently accurate and
reliable representation of the location and extent of aquatic resources within the identified review area. The location
and extent of these aquatic resources are shown on the delineation map entitled, "Figure 6. Preliminary Wetland
Boundary Map" and received 5/4/2022.
Regulatory Guidance Letter (RGL) 16-01 https://usace.contentdm.ocic.org/utils/getfile/collection/pl602lco119/id/1256
provides guidance for Jurisdictional Determinations (JD) and states, "The Corps generally does not issue a JD of any type
where no JD has been requested." Currently, we are only verifying the delineation. This delineation may be relied upon
for use in the permit evaluation process, including determining compensatory mitigation. This verification does not
address nor include any consideration for geographic jurisdiction on aquatic resources and shall not be interpreted as
such.
This delineation verification is not an Approved Jurisdictional Determination (AJD) and is not an appealable action under
the Regulatory Program Administrative Appeal Process (33 CFR Part 331). However, you may request an AJD, which is an
appealable action.
If you wish to receive a Preliminary Jurisdictional Determination (PJD), or an Approved Jurisdictional Determination (AJD)
please respond accordingly, otherwise nothing further is required and we will not provide any additional
documentation.
**Due to workload volume, the issuance of standalone JDs is not priority; however, you may use the delineation for
planning and permitting purposes.

(1) E = Ephemeral, I = Intermittent, P = Perennial, NP = Not Present, N/A=Not Applicable
(2) Refers to State riparian buffer rules only. Stream, wetland, or pond impacts are still subject to
applicable water quality standards and permitting requirements.
Explanation: The stream(s)/pond(s) listed above has been located on the most recent published NRCS
Soil Survey of Durham County, North Carolina and/or the most recent copy of the USGS Topographic
map at a 1: 24,000 scale. Each feature that is checked "Not Subject" has been determined to not be an
intermittent stream, perennial stream, a pond connected to a stream feature, or the feature is determined
not to be present. Stream features that are checked "Subject" have been located on the property and
possess characteristics that qualify them to be subject to the buffer rules. There may be other streams
located on the property that are not depicted on the maps referenced above and are therefore not subject to
the buffer rules. However, if the stream features are present on the tract, they are subject to all other
applicable North Carolina stream standards and permitting requirements as outlined in 15A NCAC 0213,
and may be considered jurisdictional according to the US Army Corps of Engineers.
This on -site determination shall expire five (5) years from the date of this letter. Landowners or
affected parties that dispute a determination made by the DWR may request a determination by
the Director. An appeal request must be made within sixty (60) days of date of this letter. A
request for a determination by the Director shall be referred to the Director in writing. If sending
via US Postal Service: c/o DWR 401 & Buffer Permitting Supervisor; DWR — 401 & Buffer Permitting
Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617. If sending via delivery service (UPS,

Subject: Biological Assessment -Threatened and Endangered Species Survey -City of
Durham - Stagecoach Road Force Main Sewer Improvements
To Project Manager:
This Biological Assessment (BA), prepared by CDM Smith on behalf of the City of Durham for the
Southeast Farrington and Stagecoach Road Force Main Sewer Improvements Project, addresses the
proposed action in compliance with Section 7 of the Endangered Species Act (ESA) of 1973 (Title 16
United States Code [U.S.C.] § 1536 (c)), as amended. This BA evaluates the potential effects of the
proposed project on species that are listed under Section 7 of the ESA. A field survey for potential
threatened and endangered species was conducted in the project area on June 16th, 2021 and
September 2nd, 2021.
Site Description
The project is located in Durham County, North Carolina (Figures 1 and 2). The project area is
approximately 76 acres and consists of the South Durham Water Reclamation Facility (SDWRF),
existing sewer lines and maintained easements, a Dominion Energy gas line and maintained
easement, paved roadways, electric utility lines, residences, wooded areas, wetlands, and streams
(representative photographs attached). Figure 3 shows the USGS topographic map for the project
area.
Project Description
Southeast Farrington and Stagecoach Road Force Main Sewer Improvements Project includes the
following:
■ 9700' of 24" force main from Stagecoach Lift Station to South Durham WRF
■ 5600' of 8" force main from Southpoint Plantation Lift Station to South Durham WRF
Standard construction and pipe installation equipment such as cranes, excavators, dump trucks,
and similar vehicles will be used for the project. Proper erosion and sedimentation control
measures will be employed throughout the project. All work will be done in the dry.

Federally Protected Resources
A list of threatened and endangered species that may occur within the boundary of the proposed
project and/or may be affected by the proposed project was provided for the survey area by the
U.S. Fish and Wildlife Service (USFWS) through the Information for Planning and Consultation
(IPaC) system on February 17th, 2023 (attached). A field survey for the USFWS federally protected
threatened and endangered species on the list was conducted by CDM Smith within the project area
on June 161h, 2021 and September 2nd, 2021. Species that are endangered, threatened or candidate
species on the list provided for the survey area are summarized in Table 1 below.

Mammals
Tricolored bat — Proposed Endangered
USFWS Recommended Survey Window: May 1 to September 15
Species Description: The tricolored bat is distinguished by its unique tricolored fur and often
appears yellowish to nearly orange. Individual hairs are tricolored: dark gray at the base, yellowish
brown in the middle, and brown or reddish brown at the tip. It is the smallest bat species found in
the eastern and midwestern United States. Individuals have a forearm length of 31.4 to 34.1 mm
(1.24 to 1.34 in) and weigh 4.6 to 7.9 g (0.16 to 0.28 oz). Its forearms are reddish, contrasting
sharply with the black membranes of its wings. Its wingspan is 21 to 26 cm (8.3 to 10.2 in).

Page 3
Habitat: During the summer tricolored bats roost among leaf clusters of live or recently dead
deciduous hardwood trees. Tricolored bats will also roost in Spanish moss and have been observed
roosting during summer among pine needles, eastern red cedar, and occasionally human
structures. During the winter, tricolored bats hibernate in caves and mines. It forages with slow,
erratic flight in areas near water or forest edges.
Effects: Potential suitable summer roosting habitat for the tricolored bat is present in the project
area. Most of the planned improvements are within existing maintained easements or road right-of-
way. Tree clearing will be necessary in some areas of new sewer alignment. Potential suitable
foraging habitat for the tricolored bat occurs in the project area adjacent to New Hope Creek, some
smaller unnamed tributaries, and along the forest edges. Any removal of mature trees would occur
between October 15th to March 31st. The proposed project will have no effect on this species.
Bioloeical Conclusion: no effect
Clams
Atlantic Pigtoe
USFWS Recommended Survey Window: year round
Species Description: The shell of the Atlantic pigtoe is a chunky, rhombus shape, like that of a pig's
hoof/toe. Individuals from headwater areas are more elongate. There is a distinct posterior ridge.
The outer surface of the shell is yellow to dark brown and parchment -like, while the inner layer is
iridescent blue to salmon, white, or orange. Although larger specimens exist, the Atlantic pigtoe
rarely exceeds 2-inches in length. Young individuals may have greenish rays across the entire shell
surface. When collected fresh, the interior surface (nacre) in the shell tends to be salmon colored
and sometimes iridescent. Atlantic pigtoe has interlocking hinge "teeth" on the inside of the shell to
help keep the two valves in proper alignment.
Habitat: The Atlantic pigtoe has been found in multiple physiographic provinces, from the foothills
of the Appalachian Mountains, through the Piedmont and into the Coastal Plain. The Atlantic pigtoe
requires relatively fast waters with high quality riverine/large creek habitat. It is typically found in
headwaters or rural watersheds. The preferred habitat of the Atlantic pigtoe is coarse sand and
gravel at the downstream edge of riffles. It is less common in sand, cobble and mixtures of sand, silt
and detritus. The Atlantic pigtoe requires fast flowing, well oxygenated streams and is restricted to
fairly pristine habitats. Historically, the best populations existed in small creeks to larger rivers
with excellent water quality, where flows were sufficient to maintain clean, silt -free substrates. The
general pattern of its current distribution indicates that the species is currently limited to
headwater areas of drainages and most populations are represented by few individuals. In North
Carolina, aside from the Waccamaw River, it was once found in every Atlantic Slope river basin.
Effects: The project area contains several intermittent and perennial stream features, which do not
have potential habitat for Atlantic pigtoe. The intermittent streams and upper perennial streams

Page 4
are not large enough and do not have suitable water quality to support Atlanic pigtoe. New Hope
Creek in the project area is an impounded lower perennial stream within a large floodplain. It has a
very sedimentary environment without fast flowing, well oxygenated water, or riffles. Two open cut
crossings are proposed across streams. One crossing is on an intermittent stream at the very upper
most portion of its drainage. The other crossing is on New Hope Creek along the Dominion Energy
gas line between the SDWRF and NC Highway 751. The North Carolina Natural Heritage Program
(NCNHP) database does not show any elemental occurrences for this species in the project area or
within 7-miles of the project area (Figure 4). All work within streams will be done in the dry and
will be the minimum necessary to install the infrastructure. The proposed project will have no
effect on this species.
Biological Conclusion: no effect
Insects
Monarch butterfly
USFWS Recommended Survey Window: August -December
Species Description: Adult monarch butterflies are large and conspicuous, with bright orange
wings surrounded by a black border and covered with black veins. The black border has a double
row of white spots, present on the upper side of the wings. Adult monarchs are sexually dimorphic,
with males having narrower wing venation and scent patches. The bright coloring of a monarch
serves as a warning to predators that eating them can be toxic. During the breeding season,
monarchs lay their eggs on their obligate milkweed host plant (primarily Asclepias spp.), and larvae
emerge after two to five days. Larvae develop through five larval instars (intervals between molts)
over a period of 9 to 18 days, feeding on milkweed and sequestering toxic chemicals (cardenolides)
as a defense against predators. The larva then pupates into a chrysalis before emerging 6 to 14 days
later as an adult butterfly. There are multiple generations of monarchs produced during the
breeding season, with most adult butterflies living approximately two to five weeks; overwintering
adults enter into reproductive diapause (suspended reproduction) and live six to nine months.
Habitat: The monarch butterfly occurs in migratory populations that breed in summer across North
America. It occurs in a variety of habitats where it searches for its host plant milkweed. The species
is widespread in the U.S., and in Southern Canada, with the overall range extending through Central
America and the Caribbean to South America. Monarchs also occur in Hawaii, Australia, and several
Pacific islands, as well as parts of Asia, Africa, and southern Europe. The population size fluctuates
in much of its range but remains in the tens of millions in North America. In North Carolina during
the fall, winter, and early spring, they can be found basking or roosting on evergreen trees and
shrubs.
Effects: The monarch butterfly is a candidate species and not yet listed or proposed for listing.
There are generally no Section 7 requirements for candidate species. The proposed project will
have no effect on this species.

Biological Conclusion: no effect
Plants
Michaux's sumac
USFWS Recommended Survey Window: May to October
Species Description: Michaux's sumac is a rhizomatous, densely hairy shrub, with erect stems from
1 to 3-feet in height. The compound leaves contain evenly serrated, oblong to lanceolate, acuminate
leaflets. Most plants are unisexual; however, observations have revealed plants with both male and
female flowers on one plant. The flowers are small, borne in a terminal, erect, dense cluster, and
colored greenish yellow to white. Flowering usually occurs from June to July; while the fruit, a red
drupe, is produced through the months of August to October.
Habitat: Michaux's sumac, endemic to the inner Coastal Plain and lower Piedmont, grows in sandy
or rocky, open, upland woods on acidic or circumneutral, well -drained sands or sandy loam soils.
The species is also found on sandy or submesic loamy swales and depressions in the fall line
Sandhills region as well as in openings along the rim of Carolina bays; maintained railroad,
roadside, power line, and utility rights -of -way; areas where forest canopies have been opened up by
blowdowns and/or storm damage; small wildlife food plots; abandoned building sites; under sparse
to moderately dense pine or pine/hardwood canopies; and in and along edges of other artificially
maintained clearings undergoing natural succession. In the central Piedmont, it occurs on clayey
soils derived from mafic rocks. The plant is shade intolerant and, therefore, grows best where
disturbance (e.g., mowing, clearing, grazing, periodic fire) maintains its open habitat.
Effects: The project area contains maintained easements and roadway right-of-way with potential
suitable habitat for Michaux's sumac. The NCNHP database does not show elemental occurrences
for this species in the project area or within 9-miles of the project area (Figure 4). The closest
current elemental occurrence is 11-miles from the project area. Michaux's sumac was not observed
during the field survey. The proposed project action may affect, but is not likely to adversely affect
this species.
Biological Conclusion: may affect, but is not likely to adversely affect
Smooth conef lower
USFWS Recommended Survey Window: late May to October
Species Description: Smooth coneflower is a rhizomatous perennial herb that grows up to 5-feet
tall from a vertical root stock. The stems are smooth, with few leaves. The largest leaves are the
basal leaves, which reach 8-inches in length and 3-inches in width, have long stems, and are
elliptical to broadly lanceolate, tapering to the base, and smooth to slightly rough. Mid -stem leaves
have shorter stems or no stems and are smaller in size than the basal leaves. The rays of the flowers

Page 6
(petal -like structures) are light pink to purplish, usually drooping, and 2 to 3.2-inches long. Flower
heads are usually solitary, with flowering occurring from May through July.
Habitat: The habitat of smooth coneflower is open woods, cedar barrens, roadsides, clearcuts, dry
limestone bluffs, and utility line right-of-way, usually on magnesium- and calcium -rich soils.
Optimal sites are characterized by abundant sunlight and little competition in the herbaceous layer.
Natural fires, as well as large herbivores, are part of the history of the vegetation in this species'
range.
Effects: The project area contains maintained easements and roadway right-of-way with potential
suitable habitat for smooth coneflower. The NCNHP database does not show any elemental
occurrences for this species in the project area or within 2-miles of the project area (Figure 4). The
closest current elemental occurrence is 11-miles from the project area. Smooth coneflower was not
observed during the site survey. The proposed project action may affect, but is not likely to
adversely affect this species.
Biological Conclusion: may affect, but is not likely to adversely affect
Critical Habitat
There is no critical habitat within the boundary of the proposed project area (IPaC report dated
February 17th, 2023).

Page 7
Conclusions and Determination
Potential habitat for Tricolored bat, Michaux's sumac and smooth coneflower is present in the
project area. The proposed project is designed primarily within existing maintained easements and
road right-of-way, and the minimum necessary to perform the improvements. Any removal of
mature trees would occur between October 15th to March 31st. Based on the minimal planned
impacts, the potential benefits of continued disturbance and maintenance of the easements, and no
observations of the listed species during the field survey, the proposed action may affect, but is not
likely to adversely affect Michaux's sumac and smooth coneflower. If you need additional
information, please contact Jason Hales at [e-mail] or 910-520-1832. Thank you
very much for your assistance.

Project Name: Stagecoach Road Force Main
February 17, 2023
Subject: List of threatened and endangered species that may occur in your proposed project
location or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. The species list fulfills the
requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the
Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). If your project area
contains suitable habitat for any of the federally -listed species on this species list, the proposed
action has the potential to adversely affect those species. If suitable habitat is present, surveys
should be conducted to determine the species' presence or absence within the project area. The
use of this species list and/or North Carolina Natural Heritage program data should not be
substituted for actual field surveys.
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through the ECOS-IPaC system by completing the same process used to receive the enclosed list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered

02/17/2023
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a biological
evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that
listed species and/or designated critical habitat may be affected by the proposed project, the
agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service
recommends that candidate species, proposed species and proposed critical habitat be addressed
within the consultation. More information on the regulations and procedures for section 7
consultation, including the role of permit or license applicants, can be found in the "Endangered
Species Consultation Handbook" at:
http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF
Migratory Birds: In addition to responsibilities to protect threatened and endangered species
under the Endangered Species Act (ESA), there are additional responsibilities under the
Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to
protect native birds from project -related impacts. Any activity, intentional or unintentional,
resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by
the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more
information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php.
The MBTA has no provision for allowing take of migratory birds that may be unintentionally
killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to
comply with these Acts by identifying potential impacts to migratory birds and eagles within
applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan
(when there is no federal nexus). Proponents should implement conservation measures to avoid
or minimize the production of project -related stressors or minimize the exposure of birds and
their resources to the project -related stressors. For more information on avian stressors and
recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-to-
birds.php.
In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies
to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities
that might affect migratory birds, to minimize those effects and encourage conservation measures
that will improve bird populations. Executive Order 13186 provides for the protection of both
migratory birds and migratory bird habitat. For information regarding the implementation of
Executive Order 13186, please visit https://www.fws.govibirds/policies-and-regulations/
executive-orders/e0-13186.php.

We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Code in the header of
this letter with any request for consultation or correspondence about your project that you submit
to our office.

MIGRATORY BIRDS
Certain birds are protected under the Migratory Bird Treaty Act! and the Bald and Golden Eagle
Protection Act2.
Any person or organization who plans or conducts activities that may result in impacts to
migratory birds, eagles, and their habitats should follow appropriate regulations and consider
implementing appropriate conservation measures, as described below.
1. The Migratory Birds Treaty Act of 1918.
2. The Bald and Golden Eagle Protection Act of 1940.
3. 50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)
The birds listed below are birds of particular concern either because they occur on the
USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your
project location. To learn more about the levels of concern for birds on your list and how this
list is generated, see the FAQ below. This is not a list of every bird you may find in this location,
nor a guarantee that every bird on this list will be found in your project area. To see exact
locations of where birders and the general public have sighted birds in and around your project
area, visit the E-bird data mapping tool (Tip: enter your location, desired date range and a species
on your list). For projects that occur off the Atlantic Coast, additional maps and models detailing
the relative occurrence and abundance of bird species on your list are available. Links to
additional information about Atlantic Coast birds, and other important information about your
migratory bird list, including how to properly interpret and use your migratory bird report, can be
found below.

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.

02/17/2023 3
How is the probability of presence score calculated? The calculation is done in three steps:
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.
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.
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.

MIGRATORY BIRDS FAQ
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

02/17/2023
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 list of migratory birds that potentially occur in my
specified location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern
(BCQ 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 Rapid Avian Information
Locator (RAIL)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 or migrating in my 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 query your location using the RAIL Tool and look
at the range maps provided for birds in your area at the bottom of the profiles provided for each
bird in your results. 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);

02/17/2023
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
Outer Continental Shelf project webpage.
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 Lorin.
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
