ENG FORM 4345, FEB 2019 Page 3 of 3 USACE SAW-2019-00296 Request for Modification GEOServices Project: 45-20803A 22828 Highway 87 W / Fayetteville, NC September 7, 2022 Attachment A 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 PFAS impacted surface/groundwater on the western side of the barrier wall will be withdrawn via pumping stations and routed to on -site treatment facilities.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 Seeps A, Seep A-Trib, Willis Creek Tributary and Seep B, 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 USACE SAW-2019-00296 Request for Modification GEOServices Project: 45-20803A 22828 Highway 87 W / Fayetteville, NC September 7, 2022 discharge activities west of the wall. 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 733 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 4,597 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 USACE SAW-2019-00296 Request for Modification GEOServices Project: 45-20803A 22828 Highway 87 W / Fayetteville, NC September 7, 2022 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 Due to the nature of the activities that are herein described as "impacts" to surface waters, we are requesting that a mitigation ratio for the unavoidable impacts be assessed at a 1:1 (Impacted LFT: Stream Credit) ratio for groundwater drawdown areas, and a 2:1 ratio for in -channel fill of the barrier wall area per the applicable USACE Stream Mitigation Guidelines. The impacts were determined based on conceptual models produced by Geosyntec. Alterations to natural stream geomorphology, riparian zone, substrate, and hydrology will only be directly impacted at locations where structural fill will be placed at the facility. These unavoidable and permanent impacts will result in approximately 733 LIFT of stream channel disruption. For these specific impacts, we are request a mitigation ration of 2:1. However, the other impacted areas will be limited to a change of groundwater influence, particularly to the east side of the proposed barrier wall structure. It is of our professional opinion, that the drawdown related impacts, resulting in 3,864 LIFT, should qualify for a 1:1 mitigation ratio due to the following factors: Minimization of geomorphological impacts, improvements to stream geochemistry, and remedial improvements to improve stream biology. The drawdown area is subject to disrupting the hydro connectivity of groundwater recharge from locations upgradient, and west of the barrier wall structure. This will not directly remove all groundwater recharge areas that are still existing east of the wall. Groundwater will continue to be heavily influenced by seasonal fluctuations, weather patterns, and most importantly, the floodplain of the Cape Fear River. No alterations to the existing stream bed, sinuosity, riparian zone, or channel substrate is proposed at areas outside the footprint of the barrier wall fill. This being known, the channels will mimic the same geomorphological attributes as before the installation of the barrier wall. Given the current state of surface water chemistry at the Chemours facility, the value of water resources is significantly undermined by the presence of PFAS. PFAS laden waters cannot be utilized as a drinking water USACE SAW-2019-00296 Request for Modification GEOServices Project: 45-20803A 22828 Highway 87 W / Fayetteville, NC September 7, 2022 source, nor a recreational value. The installation of the barrier wall upgradient of these surface waters aims to meet water quality standards that can improve functional uses of the channels by removing PFAS constituents from the bedload. The proposed alterations will be improvements to general water quality of the subject features. Without the installation of the barrier wall, and in turn a lack of groundwater drawdown, the streams would continue to exist in an impaired condition with respect to geochemistry. It is the facilities goal to improve biological conditions of downstream features stemming from the facility. To achieve this, the barrier wall must be created to limit the exposure of PFAS laden runoff towards surface waters. The barrier wall aims to restrain these specific surface waters from connecting to downstream bodies. This will create conditions that are better suited for aquatic life and habitat of riparian ecosystems nearthe vicinity of the property. The introduction of impacted waters can often times be attributed to benefit successful establishments of invasive species in the ecosystem. To create conditions where native species within the local watershed can thrive, biological conditions of the surface waters must be improved through the removal of harmful constituents. A biological lift is evident with the addition of the barrier wall and dysconnectivity of groundwater recharge from upgradient sources. For the rational listed in above paragraphs, we wish to propose a mitigation ratio for the SAW-2019-00296 permit modification as a hybrid of 2:1 and 1:1 credit to debit value. Factored in at the respective lengths of 733 LFT of fill impacts and 3,864 LFT of drawdown impacts, we propose a total impact length of 4,597 LFT will require 5,330 LFT of mitigation credits. We believe that through the alterations of jurisdictional waters proposed, the Chemours Company is taking the preferred steps in order to better accommodate the community in the vicinity. A total of824 LFT of mitigation credits have been reserved through Davey Resource Group for a site located within the same HUC-08 as the project area. Documentation containing credit reservations is provided as Attachment V The remaining credits have been applied for utilizing the North Carolina Division of Mitigation Services (NCDMS) In -Lieu Fee Program. The project has been designed to minimize stream and wetland impacts while providing a potential remedy for PFAS impacts to the extent 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 USACE SAW-2019-00296 Request for Modification GEOServices Project: 45-20803A 22828 Highway 87 W / Fayetteville, NC September 7, 2022 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. wauW3 gN,JilgN W� Imuy]i�tig'711�'SAryi§�y skt3E) VN1MV,] I].L ON 'A VIIA�AVd w v.is�s .o IJNIMV2IQ .I ovdwI sno[s[nag wauW3 gN,JilgN W� Imuy]i�tig'711�'SAryi§�y skt3E) VNIMV,] I].L ON 'A ANVJWOD SWflO HHD HHL w v.is�s .o __ _ _ IJNI�YIF�2IQ .I �F�dL�II L�iF�d2I.LS ..��� sno[s[nag -, � �-) (�� )�� ) 0 AWIF :T TE NIT— EE 0 moo oM USACE SAW-2019-00296 Request for Modification GEOServices Project: 45-20803A 22828 Highway 87 W / Fayetteville, NC September 7, 2022 Attachment I Preliminary Plan Sheets s Geotechnical, Environmental and Materials Engineers BARRIER WALL AND GROUNDWATER EXTRACTION AND TREATMENT SYSTEM: EX -SITU CAPTURE REMEDY REVISED CONCEPTUAL DESIGN Chemours Fayetteville Works Prepared for The Chemours Company FC, LLC 22828 NC Highway 87 Fayetteville, NC 28306 Prepared by GEOServices, LLC 5559 North Lee Highway Cleveland, TN 37312 December 2021 lE6Sc h n ica I, laa TABLE OF CONTENTS 1.0 INTRODUCTION AND OBJECTIVES 2.0 SEEP CAPTURE AND REMEDY DESIGN............................................................. 1 2.1 SEEP CAPTURE BASIS OF DESIGN...................................................................... 2 2.1.1 SEEP CAPTURE................................................................................................. 3 2.1.2 COLLECTED WATER CONVEYANCE.......................................................... 3 2.2 MAINTENANCE........................................................................................................ 4 3.0 SUMMARY AND CLOSING...................................................................................... 4 Ex -Situ Capture Remedy Design i December 2021 lE6Sc h n ica I, laa LIST OF TABLES Table 1: Hydraulic Loading from Dry Weather Flow Table 2: Hydraulic Loading from Stormflow ATTACHMENTS G-1.0 Cover Sheet SC-0.1 Location Plan SC-0.2 Surge Pond — Schematic Flow Diagram SC-0.3 Drainage Areas SC-1.0 Seep A Capture System Site Plan SC-1.1 Seep A Capture System Grading Plan SC-2.0 Seep B Capture System Site Plan SC-2.1 Seep B Capture System Grading Plan SC-3.0 Seep A Tributary Capture System Site Plan SC-3.1 Seep A Tributary Capture System Grading Plan SC-4.0 Main Surge Pond Ex -Situ Capture Remedy Design ii December 2021 GENE Grim-kni[at Envimnmenlal and Materials Engineers 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. December 2021 GENE Grim-kni[at Envimnmenlal and Materials Engineers Table 1: Hydraulic Loading from Dry Weather Flow Channel Dry Weather Flow Rate (gpm) Willis Creek Tributary 39 Seep A Tributary 19 Seep A 31 Seep B 130 Weeps (7 total) 12 (each) Table 2: Hydraulic Loading from Stormflow (0.5" event in 24 hours) Channel Stormflow Volume (gallons) Willis Creek Tributary -- Seep A Tributary 26,000 Seep A 110,000 Seep B 46,000 Weeps (6 total) -- 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. December 2021 GENE Grim-kni[at Envimnmenlal 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'/z" 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. December 2021 GENE Grim-kni[at Envimnmenlal 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.

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. Monitoring Task Schedule Baseline Wetland Characterization Summer/Fall 2021 Post Remedy Monitoring Year 1 Summer 2022 Post Remedy Monitoring Year 2 Summer 2023 Post Remedy Monitoring Year 3 Summer 2024 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.

M 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.E-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.E-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. Chemours Fayetteville_WOTUS Report 10.19.20 1 October 2020 Geosyntec consultants crmynw, L1u'W11tlm. nl M.. P( 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 Region and per recent guidance issued jointly by the U.S. Environmental Protection 1 Environmental Laboratory. 1987.

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 3 Rapanos, John, et al. v. United States. 2006. 61 Circuit Court of Appeals. Docket Number 04-1034 Carabell, June, et al. v. United States. 2005. 6 h Circuit Court of Appeals.

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). 3 FINDINGS 3.1 Wetlands, Streams and Other Waters Assessment Seven wetlands and eleven streams, with one being the Cape Fear River and another Willis Creek, were delineated within the ecological survey area; all of which are identified in Table 2 and depicted on Figure 2.

Its source is headwater flow from tributaries west of the Project Area. It had recently been disturbed by timber harvest and road construction. Stream 7 flows approximately 750 feet into Stream 6. One of its tributaries, Stream 7a, meets it just north of the confluence of Stream 6. Approximate bank width was 4-6 feet with a moderate bed and bank definition. Stream bed substrate included silt, sand, and some cobble. Normal base flow depth is approximately 2-12 inches.

Stream 8 flows approximately 600 feet into the forested Wetland 7 and Stream 9, and ultimately the Cape Fear River. Approximate bank width was 4-10 feet with a clear incised water line on the bank. Stream bed substrate included silt and sand. Normal base flow depth is approximately 5-10 inches. Stream 9: 6.15-acre, Willis Creek, Perennial stream Stream 9, Willis Creek, is a perennial stream located partially within the 100-year floodplain of the Cape River, mostly in the area of its confluence with the river. Its southern and western banks form the northern boundary of the Project Area. The majority of the stream is outside of the Cape Fear River floodplain. Its source is several tributaries to the north, west, and southwest; including Streams 8 and 10. It flows approximately 2,800 feet into the Cape Fear River and its ordinary high water mark encompasses most of Wetland 7. Approximate bank width was 40-50 feet with a clear incised water line on the bank. Stream bed substrate included silt, sand, and some cobble. Normal base now depth is approximately 12-24 inches. Stream 10: 0.09-acre, Un-named, Intermittent stream Stream 10 is an intermittent stream located outside of the floodplain of the Cape Fear River. Its source is primarily stormwater flow and shallow groundwater as it flows into Stream 9, Willis Creek. Stream 10 flows approximately 400 feet into Wetland 7 and Stream 9. The approximate bank width of Stream 10 was 4 feet with a moderately defined bed and bank. Stream bed substrate included silt and clay. At the time of survey Stream 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.

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.

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. Primarily hydrology is high water table and flooding from Willis Creek.
