1. INTRODUCTION AND BACKGROUND
1.1 Project Background and Scope
Geosyntec Consultants of NC, P.C. (Geosyntec), on behalf of Chemours Fayetteville Works
(Chemours) respectfully submits this Pre -Construction Notification (PCN) requesting authorization for
an action identified as the Lock and Dam 3 Seep Diversion (Project). Chemours intends to install two
seepage diversion channels adjacent to a public boat ramp located on U.S. Army Corps of Engineers
(USACE) property at the William O'Huske Lock and Dam 3 in Bladen County, North Carolina (Figure
1). At the Project location, groundwater seepage discharges to the Cape Fear River and encroaches onto
the boat ramp during high flow events. This groundwater seepage contains per- and
polyfluoroalkyl substances (PFAS) from the Chemours facility upgradient of the USACE property.
The proposed diversion channels are measures requested by the USACE and North Carolina
Department of Environmental Quality (NCDEQ) to prevent water from flowing onto the boat ramp
and any areas frequented by the public.
The total survey area is approximately 1-acre and contains the Cape Fear River (SI) and an unnamed
intermittent stream (S2; Figure 2). The anticipated total permanent impacts to waters of United
States (WOTUS) and traditionally navigable waters (TNW) resulting from this action are 0.043-acre
(72 linear feet), summarized in Table 1.

This PCN is prepared in compliance with the notification requirements of the USACE Nationwide
Permit' (NWP) program and the NCDEQ 401 Water Quality Certification (401 WQC) procedures. It
is our belief that impacts associated with this Project may be authorized under the permitting
requirements of USACE Nationwide Permit 38 (NWP 38) — Cleanup of'Hazardous and Toxic Waste
and will require an approved Individual 401 WQC from NCDEQ. Further, the Project site intersects
areas under USACE Civil Works jurisdiction, and a request for authorization in accordance with the
i 33 U.S.C. 1344, Clean Water Act, Section 404; and 33 U.S.C. 403, Rivers and Harbors Act, Section 10

USACE Wilmington District's Section 408' program is included in this PCN. The PCN Application
Form and Checklist is attached as Appendix A
1.2 Project Purpose and Need
The purpose of the Project is to implement measures to prevent groundwater seepage from encroaching
onto a public boat ramp and surrounding public shoreline recreational areas, as requested by the
USACE and NCDEQ. PFAS contaminants originate from upgradient of the Project site and remediation
actions within areas beyond the Project site are ongoing under the Consent Order and Consent Order
Addendum between Chemours and the State of North Carolina. Geosyntec conducted a jurisdictional
waters delineation at the Project site on 8 May 2024 to support Project design and planning for potential
regulatory requirements. Based on the results of the delineation, minor impacts to streambed are
required to implement the Project.
1.3 Construction
Geosyntec engineers, on behalf of Chemours, developed Project -specific plans (Appendix B) that
include the implementation of construction best management practices (BMPs) to minimize impacts
associated with stormwater runoff, erosion, and sedimentation.
Following receipt of applicable permit authorizations, the proposed construction is anticipated to begin
in during low -flow periods in 2024 and take approximately one week to install the drainage channels.
Construction activities will generally proceed as follows:
• BMP installations
• Site preparation for accessing equipment and materials into the workspace
• Excavation of trench and installation of diversion channel materials (riprap, underlain by 30-
mil high density polyethylene (HDPE) geomembrane and non -woven geotextile cushion)
• Restoration of the temporary workspaces and final stabilization
2. ENVIRONMENTAL SETTING AND POTENTIAL IMPACTS
2.1 Introduction
This section describes the affected environment and Project impacts that have the potential to be greater
than de minimis.
Prior to conducting a physical ecological assessment of the proposed Project area, a Geographic
Information Systems (GIS) desktop review was conducted using publicly available vector datasets such
as National Wetland Inventory (NWI) polygons, National Hydrography Dataset (NHD) flowlines and
waterbodies, Federal Emergency Management Agency (FEMA) National Flood Hazard Layer (NFHL)
s 33 U.S.C. 408, Rivers and Harbors Act, Section 14

viewer, U.S. Geological Survey (USGS) 1:24,000 topographic maps, USGS 3D Elevation Program
lidar derived terrain, and current/historical aerial imagery to provide a general understanding of the
landscape characteristics of the site.
Geosyntec was contracted by Chemours to complete an aquatic resources delineation. The assessment
included wetland and stream delineations as well as assessment of potential threatened and endangered
species habitats. The field visit was conducted on 8 May 2024 within the USACE William O'Huske
Lock and Dam #3 property (Figure 1). A photographic record of site characteristics is provided in
Appendix C.
The Project site is limited to the sparsely vegetated right bank of the Cape Fear River, which contains
an existing boat ramp and riprap bank stabilization. Portions of the survey area from Geosyntec's May
2024 site assessment intersects mixed hardwood forested habitat adjacent to the Project area. This
habitat includes representative canopy and midstory species such as box elder (Ater negundo) and
hackberry (Celtis occidentalis), and a dense herbaceous layer of poison ivy (Toxicodendron radicans),
perennial ryegrass (Lolium perenne), and Japanese hops (Hb774ulus japonicus).
The U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (MRCS) Web
Soil Series identified one soil type within the Project area: Congaree silt loam, frequently flooded (Cn),
which is identified as a hydric soil in Bladen County. NRCS identifies the remainder of the site as
water. The most recent published hardcopy of the NRCS Soil Survey is included in Figure 3 to fulfil
Section C(4e) of the PCN application.
2.2 Water Resources
The project area is located within the Phillips Creek -Cape Fear River subwatershed (12-digit
Hydrologic Unit Code [HUC]: 030300050104). The USEPA sets national water quality standards based
on a series of pollutants. Waters listed as impaired have a concentration of one or more of these
pollutants above the standard. Data on this section of the Cape Fear River is inconclusive in the most
recent 2022 Final 303(d) List for North Carolina; however, construction activities are not anticipated
to affect the quality assessment status of Cape Fear River or its tributaries or result in an increase of
listed pollutants.
2.2.1 Wetlands, Streams, and Other Special Aquatic Sites
Wetlands are defined by the USACE (33 CFR §328.3, 1986) and the USEPA (40 CFR §230.3, 1980)
as "areas that are inundated or saturated by surface or groundwater at a frequency and duration
sufficient to support, and that under normal circumstances do support, a prevalence of vegetation
typically adapted for life in saturated soil conditions." Many wetlands and other aquatic features,
including intermittent, and perennial streams, are considered WOTUS by the USACE and deemed
"jurisdictional" under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors
Act of 1899.

During the 8 May 2024 delineation, the survey area was assessed for wetlands using methodology
outlined in the 1987 USACE Wetland Delineation Manual4. Specifically, the presence or absence of
jurisdictional areas was determined using methods outlined in Section D, subsection 2, for on -site
inspections. The USACE Regional Supplement for the Atlantic and Gulf Coastal Plain Region, Version
2.05 was also used during field surveys. Streams on -site were evaluated using a combination of in-
house data forms and the North Carolina Division of Water Quality (NCDWQ), Methodology for
Identification of Intermittent and Perennial Streams and Their Origins (NCDWQ 2010). Geosyntec
recorded all water resources with a Global Positioning System (GPS) with submeter capabilities
(Manufacturer/Model: Trimble R1 receiver).
Within the assessed survey area, two streams (S 1 and S2) were identified and delineated. No wetlands
were observed within the survey area; however, a palustrine forested wetland (PFO) was observed
outside the survey limits, draining into S2. The survey area is dominated by S 1 (Cape Fear River) on
the central and eastern site boundaries. The ordinary high-water mark (OHWM) of S 1 was identified
based on criteria including sediment deposition, water staining, presence of wrack lines, and changes
in the vegetative community. S2 (unnamed intermittent stream) originates within the PFO area west of
the survey limits, where wetland seepage forms a channel and flows southeast out of the treeline to join
S 1. An intermittent flow regime was determined for S2 based on a NCDWQ Score of 28.75, where the
stream was most notably characterized by strong presence of iron oxidizing bacteria and presence of
biological indicators including amphibians, macro invertebrates, and wetland vegetation. Stream forms
documenting site conditions at the time of the survey are included for review (Appendix D). The
remainder of the survey area is comprised of uplands and documented through two USACE upland data
points (Appendix E).
2.2.2 Floodplains
A floodplain is the area adjacent to a water body that may be partially or fully flooded during flood
stage conditions. The 100-year floodplain is defined as the area that has a one percent chance of
flooding each year. Construction within the 100-year floodplain is regulated by a variety of state and
local governments. FEMA is responsible for mapping floodplain locations and county floodplain
administrators are often responsible for permitting work within regulated areas. The Project will
construct permanent structures within the 100-year floodplain (Figure 4), and coordination with Bladen
County's floodplain administer will occur prior to start of work.

2.2.3 Coastal Management Zone
The Project area does not occur within the North Carolina Coastal Zone boundary. As such, Chemours
will not need to coordinate with the North Carolina Division of Coastal Management for this project.
2.3 Threatened and Endangered Species
The Endangered Species Act of 1973 (ESA) provides protection and conservation for threatened and
endangered wildlife and plants. Per the ESA, it is against the law to harm, hurt, shoot, pursue, lure,
wound, kill, destroy, harass, gig, spear, ensnare, trap, capture, collect, or to attempt to engage in such
conduct with any threatened or endangered (T&E) species, or to adversely impact critical habitat. The
U.S. Fish and Wildlife Service (USFWS) maintains lists for federally listed species. In North Carolina,
the North Carolina Wildlife Resources Commission (NCWRC) manages species at a state level and the
North Carolina Natural Heritage Program (NCNHP) maintains a database of documented occurrences
of protected species and sensitive habitats.
Geosyntec prepared a Project Review Request in accordance with the procedures outlined by the
USFWS Eastern North Carolina Ecological Services (Raleigh Field Office), Project Planning and
Consultation webpage. The request package is attached (Appendix F) and will be submitted to the
Raleigh Field Office via email concurrently with this PCN submittal. Resources consulted for the
request include the USFWS Information for Planning and Consultation (IPaQ tool and NCNHP
database to determine species with potential to occur at the Project site. The NCNHP report indicates
no federally protected species have documented occurrences at the Project site, and the IPaC report
suggests the following seven species have potential to occur in vicinity of the Project:
1. Red -cockaded woodpecker (RCW; Picoides borealis), Endangered
2. Northern long-eared bat (NLEB; Myotis septentrionalis), Endangered
3. Tricolored bat (Perimyotis subflavus), Proposed Endangered
4. American alligator (Alligator mississippiensis), Similarity of Appearance (Threatened)
5. Monarch butterfly (Danaus plexippus), Candidate
6. Rough -leaved loosestrife (Lysimachia asperulaefolia), Endangered
7. American chaffseed (Schwalhea americana), Endangered
In summary, no protected species were observed during 8 May 2024 site assessment and no impacts to
protected species are anticipated as a result of the Project activities. Potentially suitable habitat was
observed within the survey area for NLEB and tricolored bat (forested areas), and American alligator
(Cape Fear River). No tree clearing or disturbance within the treeline is proposed and, a "No Effect"
determination was generated for NLEB using the USFWS NLEB Rangewide Determination Key. In
regard to aquatic species, adverse effects are not anticipated as work will occur during low -flow periods
and not require water -diversion methods in the river. Please refer to the Project Review Request
(Appendix F) for a detailed assessment of the Project's potential to affect protected species.

2.4 Cultural Resources
According to the National Historic Preservation Act (NHPA) of 1966, cultural resources include
prehistoric and historical archaeological resources, as well as architectural resources. Prehistoric
resources include evidence of human activity that predates the advent of written records. Historic
archaeological resources often include battlegrounds, campsites, roads, or other structures representing
the recorded history period of a region. Architectural resources include those of historic or aesthetic
significance (typically more than 50 years in age) and often include buildings, bridges, and dams, or
entire districts with significant structures.
The North Carolina State Historic Preservation Office (SHPO) Historic Properties mapping application
was reviewed for the Project site. The Project is adjacent to the William O'Huske Lock and Dam 3,
which is listed eligible for the National Register of Historic Places. No disturbance is proposed to the
Lock and Dam structures, and the seep diversion channels will be installed adjacent to existing modern
structures (i.e., boat ramp, riprap bank stabilization), occupying a minimal footprint of disturbance. A
project review request was prepared in accordance with SHPO's online project review procedures and
will be submitted to SHPO concurrently with this PCN submittal. Please see the attached consultation
request (Appendix G).
3. MITIGATION
The proposed Project is designed to minimize impacts to the greatest extent practicable while
accomplishing the Project purpose (i.e., preventing public access to contaminated groundwater
seepage). Impacts are limited to areas that are most accessible by the public at the boat ramp and
recreational shoreline. The project does not encroach into waters that extend beyond the forested
treeline and is primarily adjacent to areas effected by existing disturbance (riprap bank stabilization,
boat ramp).
The project will be scheduled during low -flow periods (anticipated Summer 2024) to avoid the use of
temporary de -watering methods for work below the ordinary high-water mark of the Cape Fear River.
Site access will be accomplished using existing impervious surfaces (boat ramp via Bill Hall Road) and
measures to minimize temporary soil disturbance within the temporary workspace. Site -specific BMPs
will be implemented to avoid and minimize erosion/sedimentation within the Cape Fear River.
Since the Project is being conducted as a remediation action at the request of the USACE and NCDEQ;
incorporates the aforementioned impact -reduction measures; and will result in no more than minimal
disturbance required to accomplish the Project purpose, mitigation is not proposed for this Project at
this time. Should the USACE or NCDEQ determine that mitigation is required for this Project, then a
site -specific compensatory mitigation plan will be designed and submitted for agency approval prior to
beginning construction.

4. SECTION 404 AND SECTION 10
Streams within the Project site are subject to federal regulation under Section 404 (S1 and S2) and
Section 10 (S1). Authorization for impacts is being requested under NWP 38, and subject to the
conditions described below.
4.1 Regional and General Conditions
USACE Headquarters released Public Notices dated January 13, 2021 and December 27, 2021
addressing the 32 General Conditions (GCs) applicable to use of the NWPs. In the Public Notice dated
February 4, 2022 by the USACE Wilmington District published Regional Conditions (RCs) for most
individual NWP authorizations. RCs provide additional protections for the aquatic environment that is
necessary to ensure that the NWPs authorize only those activities with no more than minimal adverse
environmental effects.
The Project was evaluated against the USACE GCs and USACE Wilmington District's RCs, and will
comply with all conditions. There are no NWP-specific RCs applicable for use of NWP 38 and no
activity -specific RCs established by the USACE Wilmington District.
5. SECTION 401
The NCDEQ, Division of Water Resources (NCDWR) denied Section 401 Water Quality Certification
(WQC) for use of NWP 38, and application for an Individual 401 WQC must be made to NCDWR.
The USACE Wilmington District and NCDEQ developed a PCN application to allow for j oint submittal
of applications for certain activities authorized through NWPs and Regional General Permits under
Sections 401, 404, and 10. The PCN form requesting authorization for the proposed project is attached
as Appendix A.
6. SECTION 408
The Project site is located on federally -owned property and intersects areas under USACE Civil Works
jurisdiction. Geosyntec, on behalf of Chemours, is requesting authorization to proceed with work
pursuant to Section 408. The referenced Civil Works project is the William O'Huske Lock and Dam 3,
and no impacts will occur to the lock and dam structures as a result of the work.

Chemours intends to construct a seepage diversion channel adjacent to a public boat ramp located on U.S. Army
Corps of Engineers property at the William O'Huske Lock and Dam 3 in Bladen County, North Carolina (Figure
1). This diversion channel is necessary to divert seepage water from the Lock and Dam Seep such that it does
not flow over the boat ramp.
4i. Describe the overall project in detail, including the type of equipment to be used:
The drainage channels will capture the seepage water as it emanates from the tree line, and will ultimately divert
it to a path that is parallel to the boat ramp. The parallel portion will be installed at a minimum 6-foot offset from
the ramp. The drainage channel will consist of a trench filled with riprap, underlain by a 30-mil high density
polyethylene (HDPE) geomembrane, with a non -woven geotextile cushion between the geomembrane and riprap
for protection. Engineering calculations were performed to determine the dimensions of the trench that will
accommodate surge flow from a 1-year storm. A design drawing of the diversion ditches is attached.
4j. Attach project drawings/site diagrams/depictions of impact areas for the proposed project.
4k. Will this activity involve dredging in wetlands or waters?
❑ Yes ® No

E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts through project design:
The proposed project is designed to minimize impacts to the greatest extent practicable while accomplishing the
project purpose (i.e., preventing public access to groundwater seepage). Impacts are limited to areas that are
most accessible by the public at the boat ramp and recreational shoreline. The project does not encroach into
waters that extend beyond the forested treeline and is primarily adjacent to areas effected by existing
disturbance (riprap bank stabilization, boat ramp).
1 b. Specifically describe measures taken to avoid or minimize proposed impacts through construction techniques:
The project will be scheduled during low -flow periods (anticipated Summer 2024) to avoid the use of temporary
de -watering methods for work below the ordinary high-water mark of the Cape Fear River. Site access will be
accomplished using existing impervious surfaces (boat ramp via Bill Hall Road) and measures to minimize
temporary soil disturbance within the temporary workspace. Site -specific Best Management Practices (BMPs)
will be implemented to avoid and minimize erosion/sedimentation within the Cape Fear River.
2. Compensatory Mitigation for Impacts to Waters of the U.S., Waters of the State, or Riparian Buffers

Remarks:
The field surveys were conducted May 8, 2024 during a period in which the region had received above normal rainfall amounts for the May month -to -date (a 0.45"
surplus from a 0.76" normal value) as of May 8. This includes recent precipitation events just prior to the surveys in which 0.12 and 1.03" were recorded on 5/5 and
5/6; respectively. The observed Year -to -Date amount was 10.86" which is a 3.62" deficit according to the National Weather Service Fayetteville Area, SC climate
station. Considering recent rainfall but overall deficit for the year, the delineators felt that surface hydrology was normal with minimal stormwater influence affecting
typical surface hydrology despite the below average annual precipitation to date. No high-water, flooding conditions were observed. A review of regional drought
conditions from the website droughtmonitor.gov indicated abnormally dry conditions existed for the regional area for the week of April 30, 2024. In addition, based o
the results of the climate analysis using the Antecedent Precipitation Tool (Deter, USACE v.2.0.0) the calculated output was a -9 value "Drier that Normal' with the
graphic indicating the 30-day Rolling Total was located within the 30-Year Normal Range (see attached graphic).

To Whom It May Concern:
Geosyntec Consultants of NC, P.C. (Geosyntec), on behalf of Chemours Fayetteville Works (Chemours),
is submitting this request for project review in accordance with the U.S. Fish and Wildlife Service
(USFWS), Raleigh Field Office's online project review guidance. Geosyntec completed in-house project
review on 25 June 2024 and requests USFWS concurrence with our findings, summarized in the attached
USFWS Species Conclusions Table (Appendix A).
Background and Scope of Work
Chemours intends to construct a seepage diversion channel adjacent to a public boat ramp located on U.S.
Army Corps of Engineers property at the William O'Huske Lock and Dam 3 in Bladen County, North
Carolina (Figure 1). This diversion channel is necessary to divert seepage water from the Lock and Dam
Seep such that it does flow over the boat ramp.
Approximately 112 linear feet of diversion channel is proposed and will consist of stone riprap underlain
by a non -woven geotextile material and necessitate minor excavation/grading. Total ground disturbance is
approximately 0.1-acre. No tree disturbance is proposed for this project. Construction of the diversion
channel involves permanent fills below the ordinary high-water mark of the Cape Fear River, and
authorization from the USACE, Wilmington District will be requested for proposed impacts to areas within
Corps jurisdiction under Section 404, Section 10, and Section 408. A Pre -Construction Notification will be
submitted to the USACE requesting coverage under Nationwide Permit No. 38 (Cleanup of Hazardous and
Toxic Waste), as well as a request for Section 408 approval. Further, an Individual 401 Water Quality
Certification will be requested from NCDEQ, Division of Water Resources.

Site access will be accomplished from the boat ramp via Bill Hall Road. Following receipt of applicable
permit authorizations, the proposed construction is anticipated to begin in during low -flow periods in
Summer 2024 and take approximately one week to install the drainage channels.
Required Project Review Documentation
Defined Action Area and IPaC Species List: Geosyntec consulted the USFWS Information for Planning
and Consultation (IPaC) tool to determine the project action area and identify federally protected or
sensitive species with potential to be impacted by project activities (IPaC Project Code 2024-0085242;
Appendix B). Seven species were identified in the IPaC report as potentially occurring at the project site:
1. Red -cockaded woodpecker (RCW; Picoides borealis), Endangered
2. Northern long-eared bat (NLEB; Myotis septentrionalis), Endangered
3. Tricolored bat (Perimyotis suhflavus), Proposed Endangered
4. American alligator (Alligator mississippiensis), Similarity of Appearance (Threatened)
5. Monarch butterfly (Danaus plexippus), Candidate
6. Rough -leaved loosestrife (Lysimachia asperulaefolia), Endangered
7. American chaffseed (Schwalhea americana), Endangered
State Coordination: The North Carolina Natural Heritage Program (NCNHP) conducted a database review
of the project action area for documented occurrences of federally protected species. The NCNHP report
indicates no occurrences of federally listed species are documented on -site (Appendix C).
Habitat Assessment: Qualified Geosyntec biologists conducted a field reconnaissance on 8 May 2024 to
determine if suitable habitat is present for species identified in the IPaC Species List and NCNHP report.
Please see the attached photographic record illustrating current site conditions (Appendix D) and the results
of the habitat evaluation, summarized in Table 1.
Critical Habitat: The project does not intersect designated Critical Habitat according to the IPaC Report and
USFWS Critical Habitat Mapper.
Eagle Protection: Neither the IPaC report nor the NCNHP report documents bald eagle nesting areas in the
project vicinity. Further, the project will not require tree clearing or blasting, and loud noise components
will be minimal.
Northern long-eared bat: No tree clearing is proposed and no NLEB hibernacula (caves/mines) were
observed on -site. Further, Geosyntec evaluated the site using the USFWS Northern Long-eared Bat
Rangewide Determination Key, which resulted in a determination of "no effect" (Appendix E).

Red -cockaded woodpecker - Moore County Only The project is not located in Moore County, therefore
RCW project review guidelines are not applicable. RCW is listed on the IPaC Species List for the project
site, but no suitable habitat or RCW individuals were observed.

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 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 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

Project code: 2024-0085242
05/02/2024 19:23:14 UTC
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:
https://www.fws. gov/sites/default/files/documents/endangered-species-consultation-
handbook.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/program/migratory-bird-permit/what-
we-do.
The META 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/library/collections/threats-birds.
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.gov/partner/council-conservation-
migratory-birds.

ENDANGERED SPECIES ACT SPECIES
There is a total of 7 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include
species that exist in another geographic area. For example, certain fish may appear on the species
list because a project could affect downstream species. Note that 1 of these species should be
considered only under certain conditions.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA
Fisheriesl, as USFWS does not have the authority to speak on behalf of NOAA and the
Department of Commerce.
See the "Critical habitats" section below for those critical habitats that lie wholly or partially
within your project area under this office's jurisdiction. Please contact the designated FWS office
if you have questions.

RE: Geosyntec Consultants, Inc. -Cape Fear River
Dear Mackenzie Wallace:
D. Reid Wilson, Secretary
Misty Buchanan
Deputy Director, Natural Heritage Program
NCNHDE-25913
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached `Documented Occurrences' tables and map.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is documented within the project area or indicated within a one -mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund
easement, or an occurrence of a Federally -listed species is documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact the NCNHP at natural.heritageLdncr.nc.gov.
Sincerely,
NC Natural Heritage Program

Project code: 2024-0085242
Project Name: Chemours - Fayetteville
Federal Nexus: yes
Federal Action Agency (if applicable): Army Corps of Engineers
Subject: Record of project representative's no effect determination for 'Chemours -
Fayetteville'
Dear Mackenzie Wallace:
This letter records your determination using the Information for Planning and Consultation
(IPaC) system provided to the U.S. Fish and Wildlife Service (Service) on May 30, 2024, for
'Chemours - Fayetteville' (here forward, Project). This project has been assigned Project Code
2024-0085242 and all future correspondence should clearly reference this number. Please
carefully review this letter.
Ensuring Accurate Determinations When Using IPaC
The Service developed the IPaC system and associated species' determination keys in accordance
with the Endangered Species Act of 1973 (ESA; 87 Stat. 884, as amended; 16 U.S.C. 1531 et
seq.) and based on a standing analysis. All information submitted by the Project proponent into
IPaC must accurately represent the full scope and details of the Project.
Failure to accurately represent or implement the Project as detailed in IPaC or the Northern
Long-eared Bat Rangewide Determination Key (Dkey), invalidates this letter. Answers to certain
questions in the DKey commit the project proponent to implementation of conservation
measures that must be followed for the ESA determination to remain valid.
Determination for the Northern Long -Eared Bat
Based upon your IPaC submission and a standing analysis, your project has reached the
determination of "No Effect" on the northern long-eared bat. To make a no effect determination,
the full scope of the proposed project implementation (action) should not have any effects (either
positive or negative), to a federally listed species or designated critical habitat. Effects of the
action are all consequences to listed species or critical habitat that are caused by the proposed

Project code: 2024-0085242 IPaC Record Locator: 746-144149278 05/30/2024 21:24:47 UTC
action, including the consequences of other activities that are caused by the proposed action. A
consequence is caused by the proposed action if it would not occur but for the proposed action
and it is reasonably certain to occur. Effects of the action may occur later in time and may
include consequences occurring outside the immediate area involved in the action. (See §
402.17).
Under Section 7 of the ESA, if a federal action agency makes a no effect determination, no
consultation with the Service is required (ESA §7). If a proposed Federal action may affect a
listed species or designated critical habitat, formal consultation is required except when the
Service concurs, in writing, that a proposed action "is not likely to adversely affect" listed species
or designated critical habitat [50 CFR §402.02, 50 CFR§402.13].
Other Species and Critical Habitat that May be Present in the Action Area
The IPaC-assisted determination for the northern long-eared bat does not apply to the following
ESA -protected species and/or critical habitat that also may occur in your Action area:
■ American Alligator Alligator mississippiensis Similarity of Appearance (Threatened)
■ American Chaffseed Schwalbea americana Endangered
■ Monarch Butterfly Danaus plexippus Candidate
■ Red -cockaded Woodpecker Picoides borealis Endangered
■ Rough -leaved Loosestrife Lysimachia asperulae folio Endangered
■ Tricolored Bat Perimyotis sub flavus Proposed Endangered
You may coordinate with our Office to determine whether the Action may affect the animal
species listed above and, if so, how they may be affected.
Next Steps
Based upon your IPaC submission, your project has reached the determination of "No Effect" on
the northern long-eared bat. If there are no updates on listed species, no further consultation/
coordination for this project is required with respect to the northern long-eared bat. However, the
Service recommends that project proponents re-evaluate the Project in IPaC if: 1) the scope,
timing, duration, or location of the Project changes (includes any project changes or
amendments); 2) new information reveals the Project may impact (positively or negatively)
federally listed species or designated critical habitat; or 3) a new species is listed, or critical
habitat designated. If any of the above conditions occurs, additional coordination with the
Service should take place to ensure compliance with the Act.
If you have any questions regarding this letter or need further assistance, please contact the
Raleigh Ecological Services Field Office and reference Project Code 2024-0085242 associated
with this Project.

DETERMINATION KEY RESULT
Based on the information you provided, you have determined that the Proposed Action will have
no effect on the Endangered northern long-eared bat (Myotis septentrionalis). Therefore, no
consultation with the U.S. Fish and Wildlife Service pursuant to Section 7(a)(2) of the
Endangered Species Act of 1973 (87 Stat. 884, as amended 16 U.S.C. 1531 et seq.) is required
for those species.
QUALIFICATION INTERVIEW
1. Does the proposed project include, or is it reasonably certain to cause, intentional take of
the northern long-eared bat or any other listed species?
Note: Intentional take is defined as take that is the intended result of a project. Intentional take could refer to
research, direct species management, surveys, and/or studies that include intentional handling/encountering,
harassment, collection, or capturing of any individual of a federally listed threatened, endangered or proposed
species?
No
2. Your project overlaps with an area where northern long-eared bats may be present year-
round. Time -of -year restrictions may not be appropriate for your project due to bats being
active all year.
Do you understand that your project may impact bats at any time during the year and time -
of -year restrictions may not apply to your project?
Yes
3. The action area does not overlap with an area for which U.S. Fish and Wildlife Service
currently has data to support the presumption that the northern long-eared bat is present.
Are you aware of other data that indicates that northern long-eared bats (NLEB) are likely
to be present in the action area?
Bat occurrence data may include identification of NLEBs in hibernacula, capture of
NLEBs, tracking of NLEBs to roost trees, or confirmed NLEB acoustic detections. Data
on captures, roost tree use, and acoustic detections should post-date the year when white -
nose syndrome was detected in the relevant state. With this question, we are looking for
data that, for some reason, may have not yet been made available to U.S. Fish and Wildlife
Service.
No
4. Does any component of the action involve construction or operation of wind turbines?
Note: For federal actions, answer `yes' if the construction or operation of wind power facilities is either (1) part
of the federal action or (2) would not occur but for a federal agency action (federal permit, funding, etc.).
No

Project code: 2024-0085242 IPaC Record Locator: 746-144149278 05/30/2024 21:24:47 UTC
5. Is the proposed action authorized, permitted, licensed, funded, or being carried out by a
Federal agency in whole or in part?
Yes
6. Is the Federal Highway Administration (FHWA), Federal Railroad Administration (FRA),
or Federal Transit Administration (FTA) funding or authorizing the proposed action, in
whole or in part?
No
7. Are you an employee of the federal action agency or have you been officially designated in
writing by the agency as its designated non-federal representative for the purposes of
Endangered Species Act Section 7 informal consultation per 50 CFR § 402.08?
Note: This key may be used for federal actions and for non-federal actions to facilitate section 7 consultation and
to help determine whether an incidental take permit may be needed, respectively. This question is for information
purposes only.
No
8. Is the lead federal action agency the Environmental Protection Agency (EPA) or Federal
Communications Commission (FCC)? Is the Environmental Protection Agency (EPA) or
Federal Communications Commission (FCC) funding or authorizing the proposed action,
in whole or in part?
No
9. Is the lead federal action agency the Federal Energy Regulatory Commission (FERC)?
No

10. Have you determined that your proposed action will have no effect on the northern long-
eared bat? Remember to consider the effects of anv activities that would not occur but for
the proposed action.
If you think that the northern long-eared bat may be affected by your project or if you
would like assistance in deciding, answer "No" below and continue through the key. If you
have determined that the northern long-eared bat does not occur in your project's action
area and/or that your project will have no effects whatsoever on the species despite the
potential for it to occur in the action area, you may make a "no effect" determination for
the northern long-eared bat.
Note: Federal agencies (or their designated non-federal representatives) must consult with USFWS on federal
agency actions that may affect listed species [50 CFR 402.14(a)]. Consultation is not required for actions that will
not affect listed species or critical habitat. Therefore, this determination key will not provide a consistency or
verification letter for actions that will not affect listed species. If you believe that the northern long-eared bat may
be affected by your project or if you would like assistance in deciding, please answer "No" and continue through
the key. Remember that this key addresses only effects to the northern long-eared bat. Consultation with USFWS
would be required if your action may affect another listed species or critical habitat. The definition of Effects of

11. Your project overlaps with an area where northern long-eared bats may be present year-
round.
Is suitable northern long-eared bat habitat present within 1000 feet of project activities?
Yes
12. Will the action cause effects to a bridge?
No
13. Will the action result in effects to a culvert or tunnel?
No
14. Does the action include the intentional exclusion of northern long-eared bats from a
building or structure?
Note: Exclusion is conducted to deny bats' entry or reentry into a building. To be effective and to avoid harming
bats, it should be done according to established standards. If your action includes bat exclusion and you are
unsure whether northern long-eared bats are present, answer "Yes." Answer "No" if there are no signs of bat use
in the building/structure. If unsure, contact your local U.S. Fish and Wildlife Services Ecological Services Field
Office to help assess whether northern long-eared bats may be present. Contact a Nuisance Wildlife Control
Operator (NWCO) for help in how to exclude bats from a structure safely without causing harm to the bats (to
find a NWCO certified in bat standards, search the Internet using the search term "National Wildlife Control
Operators Association bats"). Also see the White -Nose Syndrome Response Team's guide for bat control in
structures

(barn, house, or other building) known or suspected to contain roosting bats?
No
16. Will the action directly or indirectly cause construction of one or more new roads that are
open to the public?
Note: The answer may be yes when a publicly accessible road either (1) is constructed as part of the proposed
action or (2) would not occur but for the proposed action (i.e., the road construction is facilitated by the proposed
action but is not an explicit component of the project).
No
17. Will the action include or cause any construction or other activity that is reasonably certain
to increase average daily traffic on one or more existing roads?
Note: For federal actions, answer `yes' when the construction or operation of these facilities is either (1) part of
the federal action or (2) would not occur but for an action taken by a federal agency (federal permit, funding,
etc.). .

Project Description:
Chemours intends to construct a seepage diversion channel adjacent to a public boat ramp located
on U.S. Army Corps of Engineers property at the William O'Huske Lock and Dam 3 in Bladen
County, North Carolina (Figure 1). This diversion channel is necessary to divert seepage water
from the Lock and Dam Seep such that it does flow over the boat ramp.
The total project review area is approximately 1-acre, and the acreage of ground disturbance is
approximately 0.1-acre. Approximately 125 linear feet of diversion channel is proposed and will
consist of a trench filled with riprap underlain by a non -woven geotextile material and requires
minor excavation/grading. Construction of the diversion channel involves permanent fills below
the ordinary high-water mark of the Cape Fear River. Authorization from the USACE, Wilmington
District will be requested for proposed impacts to areas within Corps jurisdiction under Section
404, Section 10, and Section 408. A Pre -Construction Notification will be submitted to the USACE
requesting coverage under Nationwide Permit No. 38 (Cleanup of Hazardous and Toxic Waste),
as well as a request for Section 408 approval. Further, an Individual 401 Water Quality
Certification will be requested from NCDEQ, Division of Water Resources.
The proposed work is adjacent to the William O'Huske Lock and Dam 3 (NC SHPO Site ID
BL0261). Construction of the Lock and Dam 3 was completed in 19351, and the structure is
determined eligible for listing in the National Register of Historic Places. Current conditions in
vicinity of the lock/dam are influenced by modern structures and public access. A concrete boat
ramp and riprap bank stabilization is on the Cape Fear River's right bank, located between the
proposed seep diversion channel and the lock/dam structure. Asphalt roadways and parking areas
provide public access to the boat ramp, and picnic grounds are west of the lock/dam. Due to the
existing modern disturbances on -site and the minimal footprint of the proposed seep diversion
channel, no effects are anticipated to the William O'Huske Lock and Dam as a result of the project.
Included for your review is a map of the project area (Figure 1), photographic record and KMZ
file of the review area boundary.
Your review of this consultation package is appreciated. As discussed above Geosyntec, on behalf
of Chemours, requests your comments and/or concurrence with our effect determinations. Should
