SAW-2019-00296 — Request for Modification
Chemours Fayetteville Works — Barrier Wall Project
22828 Highway 87 West
Fayetteville, North Carolina 28306
Dear Mr. McLendon:
On October 5, 2020, The Chemours Company (Chemours) received authorization from the U.S. Army Corps of Engineers
(USACE) for the installation of a flow -through cell and in -stream treatment facility at a location designated as Seep C,
at the Chemours Fayetteville Works facility (SAW- 2019-00296). A modification to SAW-2019-00296 was granted via
email on December 18, 2020, to construct the remedial activities utilized for Seep C at the locations of Seeps A, B, and
D, flowing toward the Cape Fear River. The purpose of the barrier wall project is to comply with an Addendum to
Consent Order (CO) Paragraph 12, issued on October 12, 2020, by the North Carolina Superior Court for Bladen County
between Chemours and the State of North Carolina and Cape Fear River Watch. The CO required Chemours to develop
a remedial plan for reducing perfluoroalkyl and polyfluoroalkyl substances (PFAS) loading from Chemours Fayetteville
Work Facility to the Cape Fear River. A barrier wall is proposed to be installed to separate groundwater and surface
water flows from the Chemours plant and the Cape Fear River.
Chemours is respectfully requesting a modification to the previously issued authorization to include the installation of
a barrier wall, as shown in the attached drawings. The barrier wall will be installed above or at the 72-foot elevation
(i.e. the 100-year floodplain). The barrier wall will consist of a mix of cement, bentonite clay, and onsite soils. The
mixture will create a minimum permeability of 1x10-6 cm/sec and have a minimum thickness of 1.5-feet. The barrier
wall will extend from the surface to approximately 80-feet below existing grade. The groundwater elevation on the
upgradient side will be controlled using a network of wells and transferred to an onsite wastewater treatment plant.
GEOSen ices, LLC, 2561 Willow Point Way, Knoxville, Tennessee 37931 Phone [phone] Fax [phone]

Several groundwater seeps, identified as Seeps A, Seep A-Trib, Willis Creek and B, are located along the
alignment of the barrier wall and, as described in this submission, the barrier wall will capture surface flows
from the first %' precipitation event and groundwater upgradient the wall. The seep capture locations will include
catch basins at each identified seep to divert baseflows and the first %' rainstorm event. The water will be
transferred to pump stations where it will then be pumped to a proposed onsite surge pond. The surge pond will
transfer the water to the onsite wastewater treatment plant prior to discharge to the Cape Fear River.
Included in our attachments is the draft modeling of the anticipated groundwater drawdown after installation of the
barrier wall. Also provided is a plan view that identifies the anticipated extent of the groundwater drawdown based
on our team's projected groundwater modeling with the overlayed seeps and wetlands identified in the wetlands
and waterbodies delineation of the project area. The wetlands and waterbodies delineation was performed by
Geosyntec and submitted to USACE in September 2020.
By way of this letter and the accompanying support documentation, including ENG Form 4345, previous
authorizations, and project -specific documentation, we are respectfully requesting a modification to the previously
issued SAW-2019-00296 to include the installation of Barrier Wall. If you have any questions or need additional
information, please do not hesitate to contact Chris Butler at [phone] or via e-mail at
[e-mail].

SAW-2019-00296 — Request for Modification: Barrier Wall Project
18. Nature of Activity (Description of project, include all features)
On October 1, 2020, the North Carolina Superior Court for Bladen County entered a Consent Order (CO)
among The Chemours Company FC, LLC (Chemours) and the State of NC and Cape Fear River Watch to
address discharges of perfluoroalkyl and polyfluoralkyl substances (PFAS) at the Chemours Fayetteville
Works. As a result of the CO, Chemours must reduce the amount of impacted surface water draining
towards the Cape Fear River. As a part of the Addendum CO, a barrier wall has been proposed to capture
groundwater and surface waters from potentially discharging PFAS impacted waters to the Cape Fear
River.
Currently, flow -through cell technology is being utilized at major surface water discharges, identified as
Seeps A, B, C, and D from the facility. The flow -through cell implementation is part of a short-term
remediation schedule, and will need to be replaced with a long-term solution to reduce PFAS loading into
the Cape Fear River. The barrier wall will be constructed east of the facility in a north -south fashion and
will reduce surface/groundwater loading from the facility to the Cape Fear River. The barrier wall will be
installed above or at the 72-foot elevation (i.e. the 100-year floodplain). The barrier wall consists of a mix
of cement, bentonite clay, and onsite soils. The proposed mix design creates a minimum permeability of 1x10
-6cm/sec and installed at a minimum thickness of 1.5-feet. The barrier wall extends from the surface to
approximately 80-feet below existing grade. PFAS impacted surface/groundwater on the western side of
the barrier wall will be withdrawn via pumping stations and routed to on -site treatment facilities. With
the elimination of hydrologic connectivity between the two areas, it is expected that the presence of
surface or groundwater east of the wall will be from precipitation events, and fluctuation of groundwater
influence from the Cape Fear River. Preliminary plan sheets for the Barrier Wall and Ex -Situ Seep Capture
are included as Attachment I.
In addition to the four main seeps, numerous unnamed tributaries were identified east of, and
within the drawdown area of, the proposed barrier wall structure in the Waters of the U.S.
Findings Report; Chemours Fayetteville Works Project, Bladen and Cumberland Counties, North
Carolina; dated October 2020, prepared by Geosyntec Consultants of NC. These identified features in
the report will also be entirely hydrologically disconnected from groundwater and surficial discharge
activities west of the wall.

GEOServices Project: 45-20803A
January 24, 2022
Stream impacts at the location can be categorized into two general groups. Those for which will be
impacted due to physical displacement resulting from fill of the barrier wall structure, and those impacts
due to drawdown created from the proposed pumping system. Alterations resulting from the structural
fill will accumulate to approximately 707 Linear Feet (LFT) of impacts. Additionally, alterations resulting
from the expected groundwater drawdown area will accumulate to approximately 3,864 LFT of impacts.
The presumed alterations to existing streamflow stemming from the above -mentioned hydrologic
features will result in a total of approximately 4,571 LFT of stream impacts at the project location.
Wetlands are present within the project area and are detailed further in the Waters of the U.S. Findings
report. However, due to the nature of activities, no impact is expected to wetland features within the
project limits. Groundwater modeling of the area has been completed by Geosyntec Consultants of NC
during the development of the groundwater remedy design (Attachment II). The modeling depicted a
drawdown of groundwater on the eastern portion of the project area ranging from 4.5' below ground
surface (bgs) to 0' of drawdown. It is our professional opinion that these wetlands are within the
floodplain of the Cape Fear River, and wetland hydrology within the project area is sustained by multiple
sources other than the seeps, including position within the floodplain/micro topography and geomorphic
position. It is not likely that a drawdown of a maximum of 4.5' bgs will impact the nature of these features.
We are proposing the development and implementation of a monitoring plan for this location, including
the collection of appropriate baseline data before construction begins to validate our position that
wetlands will not be impacted in a manner that will result in degradation.
The wetland monitoring plan and Waters of the U.S. Findings Report are included as Attachment III and
Attachment IV respectively.
19. Project Purpose
The purpose of the project is to comply with the Addendum CO between Chemours, the State of NC, and
Cape Fear River Watch to address discharges of PFAS at the Chemours Fayetteville Works. According to
the Addendum CO, Chemours is required to reduce total mass loading of PFAS substances during dry
weather by at least 99%, following rain events of 0.5 inches or less must reduce mass loading by at least
95%, and capture total dry weather flow plus rain events up to 0.5 inches in a 24-hour period upgradient
of the barrier wall for all streams. The addendum to consent order paragraph 12 states in paragraph 3(B)

that "Chemours shall proceed with the design and installation of a barrier wall and groundwater extraction
system to reduce PFAS loading from groundwater flow from under the facility to the Cape Fear River and
Willis Creek".
23. Description of Avoidance, Minimization, and Compensation
The project has been designed to minimize stream and wetland impacts while providing a potential
remedy for PFAS impacts to the extant practicable. Access to the site will utilize the existing barrier wall
access road which was permitted through BLADE-2021-002 Chemours Temporary Geotechnical Access
Road Land Disturbance Permit. Chemours will compensate for unavoidable wetland and stream impacts
through the purchase of credits from an approved mitigation bank or purchase of in -lieu -fee mitigation,
as required. A draft plan for monitoring was submitted to the USACE on August 5, 2021, for review and
comment. If we observe wetlands losses in the project area following installation of the barrier wall, the
monitoring plan will allow us to quantify those impacts accurately and consult with USACE and NC DEQ,
in order to provide mitigation for them in a timely manner.

1 INTRODUCTION AND OBJECTIVES
The site for the proposed Barrier Wall and Groundwater Extraction System project is
located at the existing Chemours Fayetteville Works facility located at 22828 NC
Highway 87 in Fayetteville, North Carolina.
At the Chemours Fayetteville Works facility there are four on -site Seeps (A through D)
with identified discharges into the nearby Cape Fear River. The seeps are currently being
collected in in -situ flow -through cells to reduce loadings from the seeps to the Cape Fear
River pursuant to Consent Order Paragraph 12 Addendum (COA) paragraph 2(a). Under
the COA, the Long -Term Seep Remediation Objective is to reduce the total annual mass
loading of PFAS (as measured by indicator parameters) to the Cape Fear River from
Seeps A through D by: (i) during dry weather flow, reducing total mass by at least 99%;
(ii) during dry weather flow and following rain events of 0.5 inches or less, reduce total
mass loading by at least 95%; and (iii) for any seep that daylights upgradient of the Barrier
Wall, capture total dry weather flow plus rain events up to 0.5 inches in a 24-hour period
upgradient of the Barrier Wall and treat PFAS (as measured by indicator parameters) with
a removal efficiency of at least 99%.
The purpose of this document is to outline the conceptual design methods for the
collection of dry weather and 0.5-inch or less rain event flows from four seeps that
daylight upgradient of the Barrier Wall: Seep A, a Seep A tributary, Seep B, and a Willis
Creek tributary. The document also describes transportation of the collected water to the
on -site water treatment plant. The following sections of this document and the supporting
figures outline the design basis, capture basis, implementation, and verification methods
utilized for this portion of the design.
2 SEEPS CAPTURE REMEDY DESIGN
Per the COA, the seep remedy at the sites of seeps designated Seep A and Seep B will
consist of the ex -situ capture of dry weather baseflow and rain events up to one-half inch
in a 24-hour period. Based on topography and the observed seeps on site, the Seep A flow
and capture system is separated into two seeps designated as Seep A and Seep A tributary.
Dry weather baseflow will also be collected from the Willis Creek tributary seep and from
seven "weeps" that daylight upgradient of the Barrier Wall.
The seep remedy was developed based on flume data and catchment modeling prepared
by Geosyntec Consultants of NC, P.C. (Geosyntec). The tables outlining the flows used
for the design are included below.

The remaining sections of this document discuss the basis for the design, the collection,
storage, conveyance, and solid control and maintenance requirements for the Ex -Situ
Capture design.
2.1 Seep Capture Basis of Design
Conceptual ex -situ capture systems for both Seep A and B were described in the 60
percent design submittal pursuant to the COA. In the 60 percent design systems, the seeps
were captured and diverted to a series of storage ponds located near the seep collection
system. The ponds were designed to smooth the peak flows to the water treatment plant
while also settling solids from the seep waters very near their collection points.
2 December 2021

GE*,S
Geotechnical, Environmental and Materials Engineers
Subsequent to the 60 percent design submittal, the flow rates have been refined using new
information and the design has been modified to reduce the size of the ponds at the seep
locations while maintaining the simultaneous benefits of the equalization of flows and
solids management before the water reaches the treatment plant. Additional dry weather
flows from the Willis Creek Tributary and seven "weeps" daylighting above the Barrier
Wall have also been included in the revised design.
Based on experience at the existing treatment plant at Outfall 003, the 1/2" rainfall flow
is expected to be the most sediment laden component of the proposed network. To allow
for TSS control, the dry weather baseflow and stormflow will be pumped to a single surge
pond prior to entering the water treatment plant. The single surge pond functions similar
to the original design but combines all captured flow into one surge basin instead of
individual basins at each capture location.
2.1.1 Seep Capture
In the revised design, the seeps will still be collected in existing topographic channels or
adjacent low-lying areas, but the method of collection has changed to account for the
topography of each location.
Based on the topography and the relatively small flows, dry weather flow from the Willis
Creek Tributary and the seven surficial weeps will be collected in structures and pumped
directly to the lined surge pond.
At the Seep A Tributary and Seep B locations, the lined basin has been located and graded
such that the dry weather flow and stormflow will flow directly into the small basin
located at each location before being conveyed to the surge pond.
The flows from Seep A manifest from two drainage areas that currently (before the barrier
wall) convene into one collectable seep near the location of the temporary collection
system. Once the barrier wall is installed, the flows from the two areas will manifest
separately but close together so the revised design collects the north side of the Seep A
area and conveys it via actuated sluice gate into the lined Seep A basin located further to
the south (Sheet SC-0.3). Once both flows are collected into the Seep A basin near the
Barrier Wall, the water is conveyed to the surge pond and ultimately to the water
treatment plant.
2.1.2 Collected Water Conveyance
A series of pumps will be utilized to transport the dry weather flow and storm flow from
the individual collection locations to the large surge pond. The pump stations will provide
a steady/known flow to the surge pond via a force main system. Each seep (A and B, A
tributary) will include a pump station. The pump station will be sized to function with the
surge pond of each seep. A pump station will also be present at the Willis Creek feature.
3 December 2021

GE*,S
Geotechnical, Environmental and Materials Engineers
The purpose of the single large surge pond is to replace the functionality (solids reduction
and consistent flow rates to the treatment plant) of the original design settling basins. The
combination of peak storm flow attenuation at the site of collection and the large surge
pond provides multiple layers of surge protection for the water treatment system that is
also handling flows from other sources. The Schematic Flow Diagram is shown on Figure
SC-0.2.
2.2 Maintenance
As with all systems, general maintenance will be required. A summary of expected
weekly inspections and maintenance is listed below:
• Inspect trash rack system at Seep A
• Remove all material from pipe guard grates (debris, leaves, limbs,
sticks, etc.)
• Inspect base flow collection structures at Willis Creek Tributary and
weeps including inlet grates. Remove any debris blocking the inlet
grate.
• Measure sediment in each pond and record depths. Remove sediment,
as necessary.
• Inspect pump stations and test each pump. Remove any collected
solids.
In addition to the general maintenance listed above, the system shall be monitored during
rainfall events to ensure proper operation.
3 SUMMARY AND CLOSING
The conceptual design of ex -situ seep capture is part of the overall Barrier Wall and
Groundwater Extraction System planned to accomplish the requirements of the Consent
Order Addendum with the State of North Carolina. Hydraulic modeling results and
subsequent hydraulic loading information prepared by Geosyntec Consultants of NC,
P.C. have been utilized to prepare the conceptual design documents which are attached
to this document.
The conceptual design plan is based on the collection system for each seep functioning
as part of an equalization chain between the seep capture and the treatment plant. This
storage chain function allows the flow to the treatment plant to be controlled. The design
of the seep capture system will capture and store both the dry weather flow and the peak
flow/volume from the 1/2" rainfall event.

Seep A - Pond Notes
1. The existing elevation of the seep channel at the Barrier Road Crossing Location is higher than the adjacent low elevation of a portion of the
drainage area to Seep A. Therefore, the pond for Seep A is located in the lower area and the Dry Weather Flow and the 4" Rainfall Runoff from
Seep A will be piped to the pond.
2. Shape and volume of pond, elevations of structures and pipes are critical to operation of the pond. The intent of the pond is to capture the Dry
Weather Flow from Seep A and Weep at 50+00 and to capture the runoff from the 4" rainfall from Seep A.
3. The grades and elevations shown are final grades and elevations. The entire area shall include 3" topsoil. Thus subgrade shall be 3" lower than
grades shown on plan.
4. The entire basin and all 3:1 slopes shall include permanent seeding and erosion control matting.
5. The outlet structure is sized to allow discharge of the 100-year storm while maintaining a maximum surface water elevation of 69.68.

4" Rainfall Runoff Volume = 46,000 gallons - Elevation 67.19
Seep B - Pond Notes
1. Shape and volume of pond, elevations of structures and pipes are critical to operation of the pond. The intent of the pond is to capture the Dry
Weather Flow from Seep B and Weep at 60+00 and to capture the runoff from the rainfall.
2. The grades and elevations shown are final grades and elevations. The entire area shall include 3" topsoil. Thus subgrade shall be 3" lower than
grades shown on plan.
3. The entire basin and all 3:1 slopes shall include permanent seeding and erosion control matting.
4. The outlet structure is sized to allow discharge of the 100-year storm while maintaining a maximum surface water elevation of 69.00 (1.5' below
the emergency spillway).

1. Shape and volume of pond, elevations of structures and pipes are critical to operation of the pond. The intent of the pond is to capture the Dry
Weather Flow from Seep A Tributary and to capture the runoff from the 4" rainfall.
2. The grades and elevations shown are final grades and elevations. The entire area shall include 3" topsoil. Thus subgrade shall be 3" lower than
grades shown on plan.
3. The entire basin and all 3:1 slopes shall include permanent seeding and erosion control matting.
4. The outlet structure is sized to allow discharge of the 100-year storm while maintaining a maximum surface water elevation of 70.49. Note that
this assumes the tailwater on the outlet pipe is at elevation 68.00 (the 100-year Flood Elevation of the Cape Fear River. This is a very
conservative estimate as it assumes the Cape Fear River is at 100-year stage for the entire storm and thus there is no outflow from the pond
until the water surface elevation in the pond rises above elevation 68.00.

DRAFT
Fayetteville Works Wetlands Monitoring Plan -- Barrier Wall Impact Monitoring
This draft monitoring plan describes the approach for monitoring and measuring possible impacts
on the wetlands caused by the construction of the barrier wall at Fayetteville Works. This is an
initial draft and will be refined in consultation with the Corps of Engineers.
Baseline Wetland Characterization
To provide for accurate measure of wetland impacts due to the construction of remediation activities,
a baseline assessment will be conducted prior to the commencement of construction. This
assessment will focus on a detailed characterization of wetlands previously identified in the project
area by Geosyntec Consultants, Inc. and included in the previously submitted Wetland Delineation
Report (October 2020). Fourteen locations, corresponding with the existing U.S. Army Corps of
Engineers (USACE) Wetland Routine Data Form plots completed during the 2020 wetland
delineation (7 wetland, 7 upland), will be revisited during the baseline wetland characterization field
effort to gather additional data not included in a typical wetland delineation for the purpose of
obtaining additional baseline characteristics. In addition, two new randomly selected sample plots
will be added during the baseline assessment that will be incorporated into the monitoring program
to fully characterize the upgradient/downgradient conditions along the fringe of each wetland.
Corresponding photographs will be taken at each monitoring plot (photo point) in each cardinal
direction, along with a photo of the soil profile. Additional representative photographs will also be
taken at fixed locations which best reflect the observed hydrological conditions of the site and
surrounding habitats. The same monitoring plots and photo points will be used during each
subsequent monitoring event to evaluate changes to the site hydrology and/or any response in the
characteristics of the wetland habitats. Upon completion of the baseline characterization survey, a
report of findings complete with a photographic record and figures will be submitted to the USACE
for review prior to the remediation activities to establish baseline conditions for comparison to
subsequent monitoring results.
Post -remedy Monitoring Plan
Post -remedy monitoring will be conducted for three years following implementation of remediation
activities, consistent with anticipated requirements of the permit modification. If the performance
standards defined below are met after three years, Chemours will petition the USACE to be released
from further monitoring requirements. If performance standards are not met after three years, post -
remedy monitoring will continue until the requirements are satisfied or until impacts to wetlands are
evident, thenceforth compensatory mitigation for the impacts will be assessed by the USACE. Post -
remedy monitoring will focus on monitoring changes (if any) in hydrology and follow-on effects to
the delineated wetland habitats within the project area and assessing the areal extent of the delineated
wetlands and overall functionality of the wetland habitat.
The performance standards for this monitoring plan are as follows:
1. No non -wetland determinations at any assigned wetland monitoring point.

DRAFT
2. Maintain an average areal extent of 90 percent of the delineated wetland boundary, as tabulated
by acres unit measurement, following three years monitoring.
Pre planning Desktop Review
Prior to commencing field activities, an office desktop review will be conducted to compile reference
materials on climatic and hydraulic conditions at the site prior to each monitoring event, as climatic
events (droughts, floods, etc.) can often impact qualitative wetland characteristics. The desktop
review will enable an understanding of the current climatic conditions and allow for a calibration of
the anticipated field monitoring. Data from the National Weather Service's Fayetteville Area, NC
climate station, U.S. Geologic Survey (USGS) drought monitor, the nearest USGS river gauge for
the Cape Fear River at the W.O. Huske Dam (Station ID 02105500), the USACE's Antecedent
Precipitation Tool (APT), and available groundwater wells will be assessed against the Fall 2020
wetland delineation event, baseline assessment, and preceding monitoring events and included in the
monitoring reports.
Field Monitoring
Post -remedy field monitoring will consist of conducting site visits annually during the growing
season by qualified wetland biologists. The site visit will involve a quantitative assessment using the
USACE Routine Wetland Data Form in accordance with the 2010 Regional Supplement to the Corps
of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region — Version 2.0 at
each monitoring point identified in the baseline characterization assessment and a visual evaluation
of the physio state of the wetland and its surface hydrology. In addition, the site will be surveyed
for indications of potential negative wetland plant stressors (e.g. — lack of growth/vigor, mortality,
upland/pioneer plant competition) not related to natural climatic or storm -related damage.
Below is a schedule for field monitoring activities.

A global positioning system (GPS) receiver capable of submeter accuracy will be used for navigating
the perimeter of the wetland boundary and for collecting field data, per the USACE standard
operating procedures. GPS positions and final monitoring locations will be provided as part of the
baseline monitoring report.
Successive monitoring reports will be prepared each year, for three years, and provided to the
USACE by December 31 of the year subsequent to annual data collection. The overall objective of
each monitoring report will be to illustrate status quo, or deviation from, stipulated performance

DRAFT
standards. This will be achieved by summarizing data and providing comparisons to data collected
during previous years. Figures will be generated that identify areas of interest or concern, as well
as, trends of the wetland data forms results. For example, if the percent dominance test for a wetland
data form begins to trend towards less dominated by facultative species or if the number of hydrology
indicators are reduced, these changes will be mapped and indicated in the monitoring report.
Furthermore, a summary discussion of the monitoring event's pre -planning review and observed
surface hydrology shall be incorporated into the report. A statement defining the results of the
monitoring period, along with recommendations for specific monitoring observations/concerns, will
be provided in each report.
After Year 3 of the monitoring program, a formal wetland delineation will be conducted to compare
the areal extent with the initial Fall 2020 delineation. In accordance with standard USACE
delineation methodology, wetlands will be flagged and labeled with the feature identification (ID),
flag ID, and delineation date. A Wetland Delineation Report will be drafted with completed data
forms and tabulated acreages for each wetland feature. High -resolution figures will be generated
that show the current delineation results along with any changes in the wetland boundaries
highlighted in a contrasting color. Due to an expected maximum submeter-accuracy of the GPS data
collection, a 10 percent tolerance between areal extents will be permitted to quantify final
performance standard for this monitoring program. Since impacts to stream features will be
mitigated through purchase of compensatory mitigation credits for the project, the surface area for
ordinary high-water marks of streams will be excluded from the performance standard criteria.
If the monitoring program identifies that the performance standard cannot be achieved or if evidence
of permanent impacts to the wetlands from the activities is documented, Chemours agrees to consult
with the USACE to negotiate compensatory mitigation for impacts to wetlands.

1 INTRODUCTION
Geosyntec Consultants of NC, P.C. (Geosyntec), on behalf of Chemours Fayetteville
Works (Chemours), conducted wetlands and waterbodies delineation at a section of
Chemours Fayetteville Works adjacent to the Cape Fear River, a 137.6-acre Project Area
in Fayetteville, Bladen/Cumberland County, North Carolina (Site) (Figure 1). Below is a
summary of the site conditions documented during field surveys, a project background,
and the objectives of this work.
1.1 Site Description
The Site is located in southern Cumberland and northern Bladen County, approximately
ten miles south of the town of Fayetteville (Figure 1). The north boundary of the Site
begins along the southern edge of Willis Creek and the Site continues south, bounded on
the east by a Cape Fear River, on the west by the plant Chemours plant facility, and on
the south by Glengerry Road/Bill Hall Road. Current land use includes woodlands, a
water treatment facility, monitoring wells, and access roads. A per- and polyfluoroalkyl
substances (PFAS) containment system is being built on -site at this time.
The 137.6-acre ecological survey area (Figure 2), is composed of mixed hardwood/pine
forest habitat, monitoring wells, a water treatment facility, and several unimproved access
roads. Forested habitat within the Site is primarily mid- to late successional that naturally
regenerated following historic logging activities. Dominant canopy species include box
elder (Acer negundo), red maple (Acer rubrum), bald cypress (Taxodium distichum),
northern red oak (Quercus rubra), and sweetgum (Liquidambar styraciflua). Midstory
species include red maple (Acer rubrum), ironwood (Carpinus caroliniana), sweetgum
(Liquidambar styraciflua), and invasive shrubs such as Chinese privet (Ligustrum
sinense).
1.2 Background
In response to a Consent Order entered into between Chemours and the State of North
Carolina and the Cape Fear River Watch, Chemours contracted Geosyntec to perform a
wetlands and waterbodies investigation to collect data for the planning of proposed
remediation activities on the property and future regulatory correspondence. The project
is collectively known as the Chemours Fayetteville Works Project.

1.3 Objectives
The objective of the wetlands/waters delineation and protected species survey was to
identify wetlands and other waters (streams, open waters, etc.) within the ecological
survey area and provide a general characterization of their condition (forested/scrub-
shrub/herbaceous, degraded/pristine), and provide a preliminary determination as to their
anticipated jurisdictional status. Experienced Geosyntec biologists conducted the
wetlands and waters surveys from September 14 to 17, 2020.
The remainder of this report summarizes the methodology used in the wetland and stream
assessment, delineation results, and summary of findings.
2 WETLAND AND STREAM ASSESSMENT METHODOLOGY
In general, wetlands and other waters of the United States (U.S.) are federally protected
under Section 404 of the Clean Water Act (CWA). The definition of wetlands (40 Code
of Federal Regulations §230.3(t)) is "those 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. Wetlands generally include swamps, marshes, bogs and similar
areas."
Geosyntec performed a wetlands/waters delineation of the Site in accordance with the
three -parameter methodology outlined in the 1987 U.S. Army Corps of Engineers
(USACE) Wetlands Delineation Manual] (Manual), the Regional Supplement to the
Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain
Region2, and per recent guidance issued jointly by the U.S. Environmental Protection

Waterways Experiment Station. Vicksburg, Mississippi. 117 pages.

Agency (EPA) and the USACE that resulted from the Rapanos vs. U.S. and Carabell vs.
U.S. Supreme Court decisions3.
The three parameters required for identifying a jurisdictional wetland are as follows:
• The presence of hydrology - At each data point, the delineator evaluates the area
for evidence of hydrology. The Manual identifies both primary and secondary
hydrologic indicators, where one primary indicator or two secondary indicators
must be evident. Some examples of wetland hydrology indicators include
saturation in the upper 12 inches of the soil profile, inundation, water marks on
vegetation, drift lines, sediment deposits, drainage patterns, oxidized root
channels, and waters stained leaves.
• The presence of hydrophytic vegetation - Plant species are assigned a regionally
based facultative status, by the U.S. Department of Agriculture (USDA), which
describes a particular species' tolerance of water. A plant's facultative status
suggests habitat preference(s) in a given region with respect to its aptitude to grow
in low -oxygen (anaerobic) conditions. Hydrophytic, or "water loving", vegetation
are those plants which have adapted to growing in the anaerobic conditions
associated with prolonged saturation or flooding. Hydrophytic species can have a
facultative status of "facultative" (FAC), "facultative wet" (FACW), or "obligate"
(OBL). If, after defining a study plot that contains vegetation representative of
the larger area being described and identifying all species within it, 50 percent or
greater of all identified species have an assigned facultative status of FAC, FACW
or OBL, wetland vegetation criteria is met.
• The presence of hydric soils - Evaluating the presence of hydric soils requires that
the delineator sample the upper 12 inches of soil to obtain a profile description
and identify hydric soil indicators, such as histosols, histic epipedons, sulfidic
odor, aquic moisture regime, reducing conditions, gleyed or low-chroma colors,
concretions, etc. In most cases, hydric soils are most efficiently identified by the

profile description, where the soil coloration is compared to the Munsell Color
chart system to determine if the material meets hydric conditions.
An area is classified as a wetland only in instances where all three parameters exist (under
normal circumstances). If one or more criteria are absent, then the area is deemed an
upland. To sufficiently justify the wetland boundary line, a wetland data point and an
upland data point are obtained at each respective location (a minimum of one pair of data
points per wetland). As the delineator reviews the area and obtains data points, visible
indicators (e.g., abrupt changes in vegetation, elevation, surface water, etc.) often become
apparent, allowing the delineator to more efficiently establish the wetland boundary.
Streams were classified and characterized using North Carolina Division of Water
Quality Methodology for Identification of Intermittent and Perennial Streams and Their
Origins4. This method entails calculating a score for each stream based on its
characteristics. Streams with a score above 30 are considered perennial, 19 to 30 is
considered intermittent, and below 19 is ephemeral in nature.
Geosyntec biologists conducted on -site wetland assessments in accordance with the
methodologies prescribed by the USACE and EPA pursuant to Sections 401 and 404 of
the CWA. During the on -site wetland assessments, Geosyntec located and delineated the
boundaries of jurisdictional features within the ecological survey area as depicted in
Figure 2. Geosyntec flagged the boundaries of all delineated features with sequentially
numbered, high -visibility flagging (pink for wetlands; blue/white for streams) and
recorded the flag locations with Global Positioning System (GPS) units with submeter
capabilities (Manufacturer/Model: Trimble R-1 receiver and Trimble Geo-Explorer 7x).

10 did not exhibit normal base flow, as the surveys were conducted during the seasonal
dry period.
Stream 11: 26.68-acre, Cape Fear River, Perennial Stream/River
The Cape Fear River is the perennial river in which its western banks form the eastern
perimeter boundary of the Site. Its 500-year and 100-year floodplains and Floodway
boundaries exist within the Project Area and it serves as the primary drainage for the site
tributaries. According to Federal Emergency Management Agency (FEMA) the
established elevation for the 100-year floodplain is 68 feet, which encompasses a maj ority
of streams and wetlands identified within the Site, but less than 1/3 of the Site itself. The
approximate bank width of the Cape Fear River was 300-350 feet, and multiple wrack
lines of debris from past floods were observed within the floodplain. Stream bed substrate
included silt and sand. Normal base flow depth is greater than 6 feet. Many aquatic fishes,
reptiles, and avian species were observed within the river during survey activities.

--See Climatic Summary Below —
Remarks:
The field surveys were conducted September 14-17, 2020 during a period in which the region had received below normal rainfall amounts for the september month -
to -date (a -1.49" deficit from a 2.09" normal value) as of September 14. This includes recent precipitation events just prior to the surveys in which 0.01 ", 0.45, and
0.13" were recorded on 9/12, 9/11, and 9/9; respectively. The observed Year -to -Date amount was 43.67" which is a 10.15 surplus according to the National
Weather Service Fayetteville Area, NC climate station. Considering the recent precipation was small and preceded by dry weather, the delineators felt that surface
hydrology was normal with minimal stormwater influence affecting typical surface hydrology despite the above average annual precipitation to date. No high-water,
flooding conditions were observed. A review of regional drought conditions from the website droughtmonitor.gov indicated no drought conditions existed for the
regional area for the week of September 14, 2020. Shallow seep head associated with a backwater floodplain of the Cape Fear River. Perennial seep is the primary
hydrology. A lot of slash debris from windstorms.

Remarks:
The field surveys were conducted September 14-17, 2020 during a period in which the region had received below normal rainfall amounts for the september month -
to -date (a -1.49" deficit from a 2.09" normal value) as of September 14. This includes recent precipitation events just prior to the surveys in which 0.01 ", 0.45, and
0.13" were recorded on 9/12, 9/11, and 9/9; respectively. The observed Year -to -Date amount was 43.67" which is a 10.15 surplus according to the National
Weather Service Fayetteville Area, NC climate station. Considering the recent precipation was small and preceded by dry weather, the delineators felt that surface
hydrology was normal with minimal stormwater influence affecting typical surface hydrology despite the above average annual precipitation to date. No high-water,
flooding conditions were observed. A review of regional drought conditions from the website droughtmonitor.gov indicated no drought conditions existed for the
regional area for the week of September 14, 2020. Shallow exposed roots on many trees. Primary hydrology is seepheads and high water table.

Remarks:
The field surveys were conducted September 14-17, 2020 during a period in which the region had received below normal rainfall amounts for the september month -
to -date (a -1.49" deficit from a 2.09" normal value) as of September 14. This includes recent precipitation events just prior to the surveys in which 0.01 ", 0.45, and
0.13" were recorded on 9/12, 9/11, and 9/9; respectively. The observed Year -to -Date amount was 43.67" which is a 10.15 surplus according to the National
Weather Service Fayetteville Area, NC climate station. Considering the recent precipation was small and preceded by dry weather, the delineators felt that surface
hydrology was normal with minimal stormwater influence affecting typical surface hydrology despite the above average annual precipitation to date. No high-water,
flooding conditions were observed. A review of regional drought conditions from the website droughtmonitor.gov indicated no drought conditions existed for the
regional area for the week of September 14, 2020.

Remarks:
The field surveys were conducted September 14-17, 2020 during a period in which the region had received below normal rainfall amounts for the september month -
to -date (a -1.49" deficit from a 2.09" normal value) as of September 14. This includes recent precipitation events just prior to the surveys in which 0.01 ", 0.45, and
0.13" were recorded on 9/12, 9/11, and 9/9; respectively. The observed Year -to -Date amount was 43.67" which is a 10.15 surplus according to the National
Weather Service Fayetteville Area, NC climate station. Considering the recent precipation was small and preceded by dry weather, the delineators felt that surface
hydrology was normal with minimal stormwater influence affecting typical surface hydrology despite the above average annual precipitation to date. No high-water,
flooding conditions were observed. A review of regional drought conditions from the website droughtmonitor.gov indicated no drought conditions existed for the
regional area for the week of September 14, 2020. Primary hydrology is seepheads and high water table.

Remarks:
The field surveys were conducted September 14-17, 2020 during a period in which the region had received below normal rainfall amounts for the september month -
to -date (a -1.49" deficit from a 2.09" normal value) as of September 14. This includes recent precipitation events just prior to the surveys in which 0.01 ", 0.45, and
0.13" were recorded on 9/12, 9/11, and 9/9; respectively. The observed Year -to -Date amount was 43.67" which is a 10.15 surplus according to the National
Weather Service Fayetteville Area, NC climate station. Considering the recent precipation was small and preceded by dry weather, the delineators felt that surface
hydrology was normal with minimal stormwater influence affecting typical surface hydrology despite the above average annual precipitation to date. No high-water,
flooding conditions were observed. A review of regional drought conditions from the website droughtmonitor.gov indicated no drought conditions existed for the
regional area for the week of September 14, 2020. Primary hydrology is seepheads and a high water table.

Remarks:
The field surveys were conducted September 14-17, 2020 during a period in which the region had received below normal rainfall amounts for the september month -
to -date (a -1.49" deficit from a 2.09" normal value) as of September 14. This includes recent precipitation events just prior to the surveys in which 0.01 ", 0.45, and
0.13" were recorded on 9/12, 9/11, and 9/9; respectively. The observed Year -to -Date amount was 43.67" which is a 10.15 surplus according to the National
Weather Service Fayetteville Area, NC climate station. Considering the recent precipation was small and preceded by dry weather, the delineators felt that surface
hydrology was normal with minimal stormwater influence affecting typical surface hydrology despite the above average annual precipitation to date. No high-water,
flooding conditions were observed. A review of regional drought conditions from the website droughtmonitor.gov indicated no drought conditions existed for the
regional area for the week of September 14, 2020.

Notes:
Perennial stream, Willis Creek, shortly before it flows into the Cape Fear River. Backwater flooding occurs up the
confluence, from the Cape Fear River when it floods. S8 and S10 provide additional drainage for this stream. A
mature forested wetland consisting of baldcypress are located within the stream channel and multiple sandy sediment
"islands" are present during low water conditions.

Notes:
The Cape Fear River is perennial river with head water source from multiple upstream tributaries. Substrate is a mix of
sand and silt. The river frequently floods and inundates the floodplain within the project area. A lock and dam is
located within the river immediately downstream of the project area to provide navigable transportation and flood
control.
