INTRODUCTION This report was prepared by Geosyntec Consultants of NC, P.C. (Geosyntec) for The Chemours Company FC, LLC (Chemours) as the first semiannual report for Ongoing Sampling of the concentrations of per- and polyfluoroalkyl substances (“PFAS”) in process wastewater, non-process wastewater, and stormwater at the Chemours Fayetteville Works, North Carolina site (the Facility, Figure 1). This is the first semiannual report addressing paragraph 11(d) of the Consent Order amongst Chemours, the North Carolina Department of Environmental Quality (DEQ), and Cape Fear River Watch, entered into court on February 25, 2019. This semiannual report is a continuation of bimonthly sampling and quarterly reporting conducted under paragraph 11(c) of the Consent Order, which was an 18-month Initial Characterization of PFAS concentrations in the process wastewater, non-process wastewater, and stormwater at the Facility that is discharged through Outfall 002. At the culmination of the 18-month paragraph 11(c) Initial Characterization period, a final report summarized the findings of the paragraph 11(c) sampling events and provided recommendations for transitioning to paragraph 11(d), Ongoing Sampling. An addendum to the final report was submitted on May 28, 2021 to report bimonthly samples collected in October 2020 and November 2020. Chemours is awaiting comment from DEQ regarding these recommendations. As such, recent sampling conducted under the Ongoing Sampling program was consistent with sampling conducted during the Initial Characterization period. This semiannual report summarizes the findings for the first three (3) paragraph 11(d) sampling events during 2021 Quarters 1 and 2 and provides further support for implementing the recommendations proposed at the conclusion of the paragraph 11(c) Initial Characterization period. The remainder of this document is organized as follows:  Section 2 – Background: this section describes the Facility, the conveyance network which transmits flow to Outfall 002, locations sampled and location categories, and conclusions from the paragraph 11(c) Initial Characterization period;  Section 3 – Semi-Annual Report Objectives: this section describes the objectives of this report;  Section 4 – Paragraph 11(d) Methods and Scope: this section describes the methods employed for sample collection and analysis for 2021 Quarters 1 and 2;  Section 5 – Assessment of Paragraph 11(d) Ongoing Sampling: this section describes PFAS concentrations trends and observations in investigative samples DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 2 28-September-21 over the first semiannual period in context with paragraph 11(c) observations (2021 Quarters 1 and 2);  Section 6 – Summary and Recommendations: this section summarizes the observations of results from the first semiannual period and recommended changes to the sampling plan for ongoing sampling activities pursuant to paragraph 11(d) of the executed Consent Order; and  Section 7 – References: this section lists the documents referenced in the report. 2. BACKGROUND This section provides a summary of past paragraph 11(c) quarterly reports, an overview of how the Facility uses water, the types of water present at the site, how this water flows to the Facility’s discharge point at Outfall 002, how the locations sampled as part of paragraph 11(c) and paragraph 11(d) are grouped for interpretation, and an overview of recent site work conducted to mitigate PFAS contributions to Outfall 002. 2.1 Paragraph 11(c) Reporting Background Chemours submitted the PFAS Characterization Sampling Plan (the Sampling Plan) to DEQ on May 6, 2019 (Geosyntec, 2019a) and received written approval to implement the program from DEQ on June 19, 2019. Past quarterly reports for the Initial Characterization Period have summarized the activities conducted during the previous quarter, reported observed trends in context to previous bimonthly sampling events, and provided recommendations to implement during the next quarter. A summary of the bimonthly sampling events and supplemental investigations included in past quarterly reports for the Initial Characterization period are provided in the table below.

These areas are shown in Figure 1 and listed below:  Chemours Monomers/Ion Exchange Materials (Monomers/IXM);  Chemours Polymer Processing Aid (PPA) Area;  Kuraray Trosifol® Leased Area;  Kuraray SentryGlas® Leased Area;  DuPont Polyvinylfluoride Leased Area;  Wastewater treatment plant (WWTP); and  Power Area at the Facility (produces filtered water and demineralized water). These various areas both use and produce water which flow through the site conveyance network to Outfall 002. The site conveyance network waters are comprised of three (3) DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 4 28-September-21 water types and five (5) primary flow pathways as they combine at Outfall 002. The water types and flow pathways at the Facility are listed below: Water Types 1. Process wastewater (Note: Chemours process wastewaters are presently disposed of offsite while tenant [Kuraray and DuPont] process wastewaters are treated at the onsite WWTP prior to discharge); 2. Non-Process Wastewater (Note: Non-Process Wastewater is also commonly called non-contact cooling water [NCCW] or steam condensate); and 3. Stormwater. Flow Pathways 1. Monomers/IXM Conveyance Network (formerly Cooling Water Channel, see Section 2.4), which transmits NCCW and stormwater from the Chemours Monomers/IXM area; 2. Wood Lined Trench, which transmits NCCW from Kuraray areas and stormwater from Kuraray and limited areas in the Chemours PPA area; 3. Wastewater Treatment Plant Discharge, which transmits treated waters from the WWTP; 4. DuPont Area Ditches, which transmit NCCW and stormwater from DuPont; and 5. Open Channel to Outfall 002, which combines the above flows and transmits and discharges them through Outfall 002. 2.2.1 Locations and Location Categories Sample locations have been grouped into seven location categories developed to facilitate analysis and interpretation of data collected during this program. The location categories were developed based on locations having either (a) a common type of water (e.g., NCCW), or (b) a common spatial and flow path relationship (e.g., WWTP related locations). The seven categories are listed and briefly described below: Location Category Description Intake River Water at Facility Represents background PFAS concentrations Non-Chemours Process Wastewater Locations representing process wastewater from Kuraray and DuPont Non-Contact Cooling Water Locations representing NCCW from Kuraray and Chemours DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 5 28-September-21 Location Category Description Stormwater Locations containing only stormwater from throughout the Facility Stormwater-Non-Contact Cooling Water Locations representing commingled stormwater and NCCW Wastewater Treatment Plant Locations representing the WWTP influent and effluent and the Terracotta pipe, which prior to November 2017 transmitted Chemours process wastewater to the WWTP and was fully decommissioned in April 2021 Combined Flows to Outfall 002 Locations representing stormwater, NCCW, and process wastewater from the combined flow pathways at the Facility in the Open Channel to Outfall 002 2.3 Paragraph 11(c) Conclusions and Recommendations Chemours collected samples pursuant to the Sampling Plan for nine (9) bimonthly sampling events during the 18-month Initial Characterization period from April 2019 to September 2020. Samples were analyzed for EPA Method 537 Mod (EPA 537M) and Table 3+ Method PFAS. Summarized findings and recommendations from the Initial Characterization are listed below. Summary of Findings The following conclusions were drawn based on the samples collected during the Initial Characterization period:  The intake river water at the facility (Location 1) contains PFAS before this water is used at the Facility. PFAS detected at Location 1 represent the background level of PFAS at other sampling locations.  Across all locations, EPA 537M PFAS were not statistically different or higher than intake data with the exception of one location (23A) on the Terracotta pipe which was decommissioned as of April 21, 2021.  Non-Chemours process wastewater locations (Locations 18, 19A, 19B, and 23B) and NCCW only locations (Locations 6A, 6B, 24A, 24B, and 24C) generally had DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 6 28-September-21 low PFAS concentrations, similar to or less than those observed at the intake river water at the Facility.  The primary sources of total Table 3+ PFAS concentrations to Outfall 002 were (1) locations comprising both stormwater and non-process wastewater from the Monomers/IXM area, (2) stormwater-only locations, and (3) the WWTP effluent, including PFAS loadings from the Terracotta pipe (now decommissioned), which prior to November 2017 transmitted Chemours process water to the WWTP. The degree of PFAS contributions from the sources outlined in the last bullet above are expected to be reduced through recent site actions as summarized in Section 2.4. Summary of Recommendations from Paragraph 11(c) Initial Characterization Based on the findings from the paragraph 11(c) Initial Characterization, the following recommendations were made to the sampling program transitions to Ongoing Sampling in paragraph 11(d):  Continue analyzing EPA 537M at the intake river water at Location 1 and Location 20 only;  Upon completion of the Monomers/IXM stormwater treatment system by June 30, 20211, replace Locations 9, 10, 10A, 24A, 24B, and 24C with one new sample location representing the combined NCCW (Location 9A);  Replace locations representing inputs to the WWTP (Locations 6A, 6B, 18, 19A, 19B, 23A, 23B) with ongoing sampling of the WWTP influent (Location 22); and  Replace stormwater-only Locations 2, 3, 4, and 5 with ongoing sampling of downstream Location 7A. Chemours submitted these recommendations to DEQ as a part of the Final Quarterly Report (Geosyntec 2020d) on December 18, 2021 and requested approval from DEQ to perform the Ongoing Sampling in accordance with these recommendations by January 8, 2021; DEQ has not yet approved this request. Therefore, recent sampling conducted under the Ongoing Sampling program was consistent with sampling conducted during the Initial Characterization period. A follow-up technical discussion between Chemours and DEQ took place in June 2021 to further clarify the recommendations and request approval for future sampling events. With submittal of this report, Chemours requests approval 1 The Monomers/IXM stormwater treatment system was operational as of June 30, 2021 and is currently being monitored in accordance with the Stormwater Treatment System Sampling Plan (Geosyntec, 2021b). DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 7 28-September-21 from DEQ to perform the Ongoing Sampling in accordance with these recommendations by October 31, 2021. 2.4 Summary of Recent Site Work to Mitigate PFAS Contributions to Outfall 002 The degree of PFAS contributions from the primary sources identified during the Initial Characterization Period have been or are being mitigated through on-going actions, specifically:  Continued use of the Thermal Oxidizer and other air emissions controls at the Facility reduces aerial emissions of PFAS. This mitigates future PFAS loading to surfaces and subsequent stormwater concentrations;  Sediment is removed annually from onsite conveyance channels. Removal of sediment prevents the potential transfer of PFAS compounds from the sediment and soils in the overlying water of Outfall 002;  The Terracotta pipe, which prior to November 2017 conveyed Chemours PFAS manufacturing process water, was fully decommissioned in April 2021, reducing PFAS contributions to the WWTP2; and  Pursuant to paragraph 4(a) of the Addendum to Consent Order Paragraph 12 (CO Addendum), a Stormwater Treatment System (SWTS) has been installed and was operational as of June 30, 2021. The SWTS treats stormwater flows from the Monomers/IXM Area, up to the 1-inch design storm. This is reducing PFAS contributions from the Monomers/IXM Area to Outfall 002. Influent and effluent stormwater is being monitored as a part of the SWTS Sampling Plan (Geosyntec, 2021). 3. SEMI-ANNUAL REPORT OBJECTIVES This semiannual report summarizes the data from three bimonthly Ongoing Sampling events that have been collected to characterize PFAS in non-process wastewater, process wastewater, and stormwater at the Facility. Objectives of the first semi-annual report are to: 1) Evaluate trends and observations at each location / location category in context with conclusions drawn from the Initial Characterization Period, and 2 Kuraray process wastewater lines to the WWTP were also reconfigured due to the decommissioning of the Terracotta pipe, eliminating some sampling locations from the Sampling Plan (Geosyntec, 2019a) DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 8 28-September-21 2) Review the recommendations made for the Ongoing Sampling program based on findings from the Initial Characterization period and confirm the results from the first semiannual period of Ongoing Sampling continue to support those recommendations. 4. PARAGRAPH 11(D) METHODS AND SCOPE This section describes the methods implemented for the first semiannual Ongoing Sampling period including locations sampled, field methods implemented, and laboratory methods used. Samples were collected during wet weather on February 18 and 19, 2021 (the February 2021 event); during dry weather on April 26 and 29, 2021 and May 4 and 7, 2021 (the April/May 2021 event); and during dry weather on June 18, 2021 (the June 2021 event). This sampling was conducted as outlined in the Sampling Plan (Geosyntec, 2019a), with adjustments made based on recommendations in prior reports (Geosyntec 2019a, 2019b, 2019c, 2020a, 2020b, and 2020c). The April/May 2021 event was collected over multiple days due to construction activities including the replacement of the Terracotta pipe and installation of the SWTS infrastructure. Recommendations made in the Final Quarterly Report (Geosyntec, 2020d) are awaiting approval from DEQ; however, some changes were required due to recent site work as discussed in Section 2.4. These changes are summarized in Section 4.1. 4.1 Sample Locations Locations sampled are described in Table 1 and shown in Figures 2 and 3. Figures 2 and 3 display the sample locations prior to and after SWTS and Terracotta pipe activities described in Section 2.4, respectively. The number of samples collected during the first semi-annual period were thirty (30) in the wet February 2021 event, twenty-four (24) in the dry April/May 2021 event, and twenty-one (21) in the dry June 2021 event sampling. Table 1 provides a summary of the sample locations collected during each event. Samples were not able to be collected from some locations because they were dry during the sampling event or because recent site work prohibited sample collection or eliminated the sample locations. Additionally, some sample locations were added to characterize locations that were no longer accessible due to recent site work. A summary of the reasoning for samples that were not able collected or added to the program is listed below:  Locations 2, 3, 4, 5, 10, 11, and 13 were not sampled during the April/May 2021 and June 2021 events because they were dry. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 9 28-September-21  Locations 9 and 10A were not sampled during the June 2021 event due to construction related to the separation of stormwater and NCCW in the Monomers/IXM area.  Locations 23A (Terracotta pipe) and 23B (Kuraray laboratory process wastewater) were not sampled after the February 2021 event because the Terracotta pipe was decommissioned on April 21, 2021. The new sample location representing Location 23B is Location 23C-2.  Locations 23C-1, 23C-2, and 23C-3 were added to the sampling program as they came into services after the decommissioning of the Terracotta pipe. 4.2 Field Methods Field methods used during the Ongoing Sampling period are consistent with methods documented in previous quarterly reports. The following sub-sections summarize these field methods. 4.2.1 General Field Methods Equipment was inspected by the field program supervisor, decontaminated, and calibrated daily prior to use in the field, according to the manufacturer’s recommendations. Field parameters (e.g., pH, temperature, turbidity) were measured with a water quality meter prior to sample collection for grab samples, and for temporal composite samples, once during composite sampling (collected directly from the water stream), and once after composite sampling (collected from the autosampler reservoir). A field notebook and location-specific field forms were used to record information regarding additional items such as quality assurance/ quality control (QA/QC), sample identifications, color, odor, and other field observations. Field QA/QC samples, including blind field duplicates, equipment blanks, field blanks, and trip blanks were collected in general accordance with the Sampling Plan (Geosyntec, 2019a). Upon sample collection, labelled and containerized samples were placed inside an insulated sample cooler with ice. Prior to shipment of the samples to the laboratory, a chain of custody form was completed identifying sample locations, sample identification numbers, and specific laboratory analyses to be performed on the samples. Chain of custody forms were signed by the field personnel relinquishing the samples to the courier and were signed by the laboratory upon receipt of the cooler. 4.2.2 Grab Sampling Methods Grab samples were collected from locations where temporal variability over the course of one day was not expected. These locations include non-process wastewater only DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 10 28-September-21 locations (Locations 6A, 6B, 24A, 24B, and 24C); select process wastewater only locations (Locations 19A, 19B, and 23B); and the Sediment Basin South location (Location 21A), as identified in Table 1 and shown on Figure 2. Location 23C-2 was collected as a grab sample during the April/May 2021 event due to site construction but was collected as a temporal composite for the June 2021 event and will continue to be collected as a temporal composite moving forward. 4.2.3 Temporal Composite Sampling Methods Temporal composite samples were collected during the bimonthly sampling events from locations where variability was expected to potentially be significant within a short time frame (e.g., one day). These locations, identified in Table 1 and shown on Figure 2, include those within the site conveyance network and the intake and outfall locations, since these locations can have highly variable dissolved and suspended constituent loads over short time periods. Temporal composite samples were collected using a dedicated Teledyne 6712C autosampler equipped with a rain gauge, high-density polyethelene (HDPE) tubing, silicon tubing, and an HDPE sample reservoir. During dry sampling events, autosamplers integrated water over a four-hour sample collection period. During wet sampling events, the integration time on the autosamplers was set to correspond to the duration of the storm event. 4.2.4 Wet Event Sampling Methods The February 2021 event included a wet sampling event on February 18, 2021 and a dry sampling event on February 19, 2021. Locations that contain stormwater (Locations 1, 2, 3, 4, 5, 7A, 7B, 7C, 9, 10, 10A, 11, 12, 13, 14, 15, 20, and 21A) were sampled on February 18, 2021 during a storm event. The storm event began on February 18, 2021 at 4:30 AM and lasted through February 19, 2021 at 7:15 AM; a total of 2.01 inches of rainfall fell during the storm event. Composite samples were collected over an approximately 8-hour period. In accordance with the PFAS Characterization Sampling Plan (Geosyntec, 2019a), Locations 6A, 6B, 8, 18, 19A, 19B, 22, 23A, 23B, 24A, 24B, and 24C were collected during dry weather after rainfall ended on February 19, 2021. 4.3 Laboratory Methods Samples were analyzed for PFAS by the following methods:  Table 3+ Laboratory Standard Operating Procedure (SOP); and  EPA Method 537 Mod Laboratory SOP (EPA 537M). PFAS reported under each of these methods are listed in Table 2. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 11 28-September-21 The February 2021 and June 2021 events were analyzed using the low-level Table 3+ SOP method, with minimum reporting limits range from 2 to 20 nanograms per liter (ng/L). This is consistent with previous sampling conducted under paragraph 11. The April/May 2021 event was analyzed using the high-level Table 3+ SOP method, with higher minimum reporting limits ranging from 6.1 ng/L to 620 ng/L depending on the compound and sample. Elevated reporting limits may potentially result in some analytes being non-detect which would have otherwise been detected using the low-level Table 3+ SOP method. Laboratory analyses were performed largely in accordance with the Sampling Plan (Geosyntec, 2019a) and within the guidelines specified by the laboratory SOPs. The collection frequency of field duplicates, matrix spike / matrix spike duplicates, trip blanks, and equipment blanks was largely in accordance with the Sampling Plan (Geosyntec, 2019a). All data were reviewed using the Data Verification Module (DVM) within the LocusTM Environmental Information Management (EIM) system, which is a commercial software program used to manage data. Following the DVM process, a manual review of the data was conducted. The data usability, in view of the project’s data quality objectives, was assessed and the data were entered into the EIM system. Additional details regarding the data review process are provided in Section 5.2.1. 5. ASSESSMENT OF PARAGRAPH 11(D) ONGOING SAMPLING This section presents an assessment of the key observations during the first six (6) months of Ongoing Sampling within the context of observations from the Initial Characterization period. Observations in this section are based on total Table 3+ concentrations and total EPA 537M concentrations. The remainder of this section discusses the presentation of Table 3+ results and PFAS data observations. 5.1 Presentation of Results Table 3+ 17 Compounds For clarity, the text and figures of this report describe the Table 3+ 17 compound sums while both Table 3+ 17 compound and Table 3+ 20 compound sums are included in the tables. As reported in the Matrix Interference During Analysis of Table 3+ Compounds memorandum (Geosyntec, 2020e), matrix interference studies conducted by the analytical laboratory (TestAmerica, Sacramento) have shown that the quantitation of three compounds (R- PSDA [formerly Byproduct 4], Hydrolyzed PSDA [formerly Byproduct 5], and R-EVE) is inaccurate due to interferences by the sample matrix in both groundwater and surface water. Given the matrix interference issues, Total Table 3+ PFAS concentrations are DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 12 28-September-21 calculated and presented in the tables of this report in two ways: (i) summing over 17 of the 20 Table 3+ compounds “Total Table 3+ (sum of 17 compounds)”, i.e., excluding results of R-PSDA, Hydrolyzed PSDA, and R-EVE; and (ii) summing over 20 of the Table 3+ compounds “Total Table 3+ (sum of 20 compounds)”. Expressing these data as a range represents possible values of what these results might be without matrix interferences. In other words, the sum of all 17 compounds is likely an underestimate of the actual value while the sum of the 20 compounds is likely an overestimate of the actual value. 5.2 Results - Semiannual Period (2021 Quarters 1 and 2) This section describes the data quality, field parameter data, and investigative sample results from the February, April/May, and June 2021 events. PFAS concentrations for all sample locations in the February, April/May, and June 2021 events are provided in Appendix A. Table 3 provides the total daily precipitation within the vicinity of the Facility and the flow measured at Outfall 002 at the times of sampling events discussed in this report. Field parameters recorded during the February, April/May, and June 2021 events are provided in Appendix B. The observations and assessment described in this section are based on the following figures:  Figures 4A – 4F present time series plots for total Table 3+ concentrations. Each time series plot displays the total Table 3+ concentrations observed during each event of the Ongoing Sampling period at the intake river water at the Facility (Location 1) and at other locations as grouped by sample location type described in Section 2.2 (e.g., Stormwater, NCCW, etc.).  Figures 5A and 5B display the distribution of concentrations total Table 3+ and total EPA 537M concentration by location for all sampling locations, respectively. Samples collected prior to January 2021 are displayed in gray to provide comparison between the Ongoing Sampling period and the Initial Characterization period.  The analytical reporting limits associated with the February 2021, April/May 2021, and June 2021 event data were determined by the laboratories. As discussed in Section 4.3, the Table 3+ reporting limits for April/May 2021 were higher than previously analyzed samples. Appendix A lists the minimum reporting limits for non-detected analytes and Figures 4A – 4F symbolizes the April/May event in orange hatching to differentiate the higher reporting limits. The higher reporting limits were considered acceptable for this event because all other events, DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 13 28-September-21 including the prior nine events during the Initial Characterization Period and the subsequent June 2021 event were analyzed with lower reporting limits. TestAmerica analytical reports and the data review narrative whitebooks are provided in Appendix C. 5.2.1 Data Quality Data Management and Reporting Chemours’s Analytical Data Quality Management team currently uses the EIM system for management of analytical data, xyz Site coordinate data, and field parameter data. Validation and qualification of data are performed by AECOM who maintains the EIM system for the Chemours Fayetteville Site. Whitebooks consisting of the data review narratives and the laboratory analytical reports produced by AECOM summarize the findings of the DVM and manual review process. QA/QC Samples PFAS concentrations for all field QA/QC samples in the February 2021, April/May 2021, and June 2021 events are reported in Appendix A. The following observations were noted for the QA/QC samples:  The relative percent difference (RPD) for field duplicate pairs in the February 2021, April/May 2021, and June 2021 events were generally less than 30% for all PFAS. Where RPDs were greater than 30%, the reported results may be imprecise and were J qualified, indicating the results are estimated.  No PFAS were detected above the associated reporting limits in the February 2021, April/May 2021, and June 2021 Equipment Blanks, Trip Blanks, or Field Blanks, except for the April/May 2021 equipment blank for the autosampler, which had PS Acid detected at 2.1 ng/L. 5.2.2 Field Parameter Data Field parameters recorded during the February, April/May, and June 2021 events are provided in Appendix B for grab samples and temporal composite samples. Field parameters were measured using a Horiba U-52 model. The water quality meter was calibrated at the start of every sampling day. For grab samples, field parameters were measured once prior to sampling using a flow through cell. For temporal composite samples once during composite sampling and collected directly from the water stream. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 14 28-September-21 Recorded field parameter data observed during the February, April/May, and June 2021 events are generally in accordance with expectations for the sample locations, with the following exceptions.  Most locations had recorded pH between 5 and 10. During the February 2021 sampling event, the combined influent to the WWTP (Location 22) had pH greater than 10. During the April/May 2021 sampling event, DuPont process wastewater – Plant 1 (Location 19A) had pH less than 5.  Most locations had recorded dissolved oxygen between 5 and 11 milligrams per liter. The Chemours PPA area stormwater discharge (Location 3) had the highest dissolved oxygen measurement at 12.8 milligrams per liter during the February 2021 event.  Most locations had recorded oxidation reduction potential (ORP) between 20 and 150 millivolts (mV). The DuPont process wastewater - Plant 1 (Location 19A) had the lowest ORP reading at -11 mV during the April/May 2021 event. The Kuraray laboratory process wastewater (Location 23C-2) had the highest ORP reading at 223 mV during the April/May 2021 event suggesting greater contact with atmospheric oxygen.  Most locations had recorded turbidity between 0 and 200 nephelometric turbidity unit (NTU). The combined Chemours Monomers/IXM NCCW and stormwater discharge (Location 10A) and the WWTP combined influent (Location 22) had turbidity measurements greater than 200 NTU during the April/May 2021 event at 376 and 2,253 NTU, respectively. 5.3 Conveyance Network PFAS Data Observations Observations from the first six months of the Ongoing Sampling period are generally consistent with previous sampling events and further support the conclusions and recommendations from the Paragraph 11(c) Final Quarterly Report (Geosyntec, 2020d). A summary of observations from the first six months of Ongoing Sampling is provided below.  The intake river water at the facility (Location 1) continues to contain PFAS before this water is used at the Facility. PFAS detected at Location 1 represent the background level of PFAS at other sampling locations.  Consistent with previous samples collected during the Initial Characterization period, EPA 537M PFAS across all locations were similar to Location 1, the intake river water at the Facility (Figure 5B). This continues to support: (1) the Initial Characterization period conclusion that the site is not a significant contributor of EPA 537M PFAS to Outfall 002, and (2) the Initial Characterization DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 15 28-September-21 period recommendation of analyzing EPA 537M PFAS at Location 1 and Location 20 (Outfall 002) only.  The distribution of Table 3+ PFAS for sample locations during the Ongoing Sampling Period was generally within the range observed from samples collected in 2019 and 2020 (Figure 5A). Recent site work conducted to reduce PFAS contributions to Outfall 002, including decommissioning of the Terracotta pipe and collection and conveyance of stormwater from the Monomers/IXM area to the stormwater treatment system, was completed in April 2021 and June 2021, respectively. The impact of this site work in reducing PFAS contributions is therefore not reflected in the samples collected during the first semiannual period of Ongoing Sampling and will continue to be evaluated in future bimonthly sampling events.  Non-Chemours process wastewater locations (Locations 18, 19A, 19B, 23B, 23C- 1, 23C-2, and 23C-3) and NCCW only locations (Locations 6A, 6B, 24A, 24B, and 24C) continue to have low PFAS concentrations, similar to or less than those observed at the intake river water at the Facility (Figure 4A, Figure 4B, Figure 5A, Figure 5B). This supports replacing these locations with ongoing sampling of the combined influent to the WWTP (Location 22), as recommended in the Final Quarterly Report (Geosyntec, 2020d).  Stormwater-only locations continue to show elevated concentrations compared to the intake river water at the Facility (Location 1), with the highest concentrations represented at the stormwater-only location in the Monomers/IXM area (Location 10) (Figure 4C). As of June 30, 2021, stormwater from the Monomers/IXM area is now being collected and treated per CO Addendum paragraph 4(a).  During the wet February 2021 event, locations comprising both stormwater and non-process wastewater from the Monomers/IXM area (Locations 7C, 9, 10A, and 15) showed elevated concentrations compared to the intake river water at the Facility and other stormwater-NCCW locations (Figures 4D and 4F). Elevated PFAS concentrations were also reflected in Outfall 002 (Location 20) in the February 2021 event (Figure 4F). The SWTS was commissioned on June 30, 2021 and was not yet operational for this event; future wet events will evaluate the effect of stormwater treatment from the Monomers/IXM area on PFAS concentrations observed at Outfall 002.  Locations 23A and 23B are no longer a source of PFAS to Outfall 002 because the Terracotta pipe was decommissioned in April 2021. These locations were therefore no longer accessible after the February 2021 event and have been removed from the sampling program (Figure 4B, Figure 4E, Figure 6). DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 16 28-September-21  Locations 24A, 24B, and 24C have been removed from the sampling program because they are no longer accessible due to the separation of stormwater and NCCW in the Monomers/IXM area. These sources of water are planned to be represented at a single point representing combined NCCW from the Monomers/IXM area in future sampling events (Location 9A, Figure 6). Based on these observations, the conclusions and recommendations drawn from the Initial Characterization period are supported, as discussed below. Subsequent bimonthly sampling during the remaining 18 months of the Ongoing Sampling period will provide more information on the impact of recent site work on PFAS concentrations at Outfall 002. 6. SUMMARY AND RECOMMENDATIONS Pursuant to Consent Order paragraph 11(d), this semiannual report summarizes results and observations from the first three (3) bimonthly sampling events collected during the Ongoing Sampling period. The objective of the Ongoing Sampling period is to continue to characterize the concentrations of PFAS in the raw water intake, process wastewater, non-process wastewater, and stormwater at the Facility. Observations and trends from the Ongoing Sampling period continue to support the findings from the Initial Characterization period. Results from the Ongoing Sampling program support Initial Characterization findings including:  The intake river water is a background source of PFAS;  The site is not a significant contributor of EPA 537M PFAS to Outfall 002;  Non-Chemours process wastewater and NCCW are not significant contributors of Table 3+ PFAS to Outfall 002; and  The primary sources of Table 3+ PFAS to Outfall 002 are stormwater-only locations and locations comprising both stormwater and NCCW from the Monomers/IXM area. The SWTS was commissioned on June 30, 2021 and is expected to reduce PFAS concentrations at Outfall 002 with the treatment of stormwater from the Monomers/IXM area. Observations from the Ongoing Sampling period also continue to support the recommendations to the sampling program that were made based on findings from the Initial Characterization period. These recommendations are summarized based on current site conditions as follows: DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 17 28-September-21  Continue analyzing EPA 537M at the intake river water at Location 1 and Location 20 only;  Replace Locations 9, 10, 10A with one new sample location representing the combined NCCW at Location 9A;  Replace the current locations representing inputs to the WWTP (Locations 6A, 6B, 18, 19A, 19B, 23C-1, 23C-2, and 23C-3) with ongoing sampling of the WWTP influent (Location 22); and  Replace stormwater-only Locations 2, 3, 4, and 5 with ongoing sampling of downstream Location 7A. Based on recent site work, the following locations no longer exist and have been removed from the sampling program:  Locations 23A and 23B no longer exist due to the decommissioning of the Terracotta pipe; and  Locations 24A, 24B, and 24C no longer exist due to the separation of stormwater and NCCW for treatment of stormwater from the Monomers/IXM area. Pursuant to paragraph 11(d), Chemours will continue to collect bimonthly samples to characterize PFAS in the intake river water, process wastewater, non-process wastewater, and stormwater at the Facility through December 2022. The proposed sampling locations for the remainder of paragraph 11(d) are identified in Figure 6. Chemours requests approval from DEQ to perform the Ongoing Sampling in accordance with these recommendations by October 31, 2021. Results will continue to be reported semi- annually, i.e. every-other quarter, within 90 days of the previous semiannual period. The next semiannual report will be submitted within 90 days of the end Quarter 4, 2021. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF TR0807E 18 28-September-21 7.

The electronic data submitted for this project was reviewed via the Data Verification Module (DVM) process.

The lab reports due to a large page count are stored on a network shared drive and are available to be posted on external shared drives, or on a flash drive. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF Data Verification Module (DVM) The DVM is an internal review process used by the ADQM group to assist with the determination of data usability. The electronic data deliverables received from the laboratory are loaded into the Locus EIM™ database and processed through a series of data quality checks, which are a combination of software (Locus EIM™ database Data Verification Module (DVM)) and manual reviewer evaluations. The data is evaluated against the following data usability checks: • Field and laboratory blank contamination • US EPA hold time criteria • Missing Quality Control (QC) samples • Matrix spike (MS)/matrix spike duplicate (MSD) recoveries and the relative percent differences (RPDs) between these spikes • Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • Difference/RPD between field duplicate sample pairs • RPD between laboratory replicates for inorganic analyses • Difference/percent difference between total and dissolved sample pairs There are two qualifier fields in EIM: Lab Qualifier is the qualifier assigned by the lab and may not reflect the usability of the data. This qualifier may have many different meanings and can vary between labs and over time within the same lab. Please refer to the laboratory report for a description of the lab qualifiers. As they are lab descriptors they are not to be used when evaluating the data. Validation Qualifier is the 3rd party formal validation qualifier if this was performed. Otherwise this field contains the qualifier resulting from the ADQM DVM review process. This qualifier assesses the usability of the data and may not equal the lab qualifier. The DVM applies the following data evaluation qualifiers to analysis results, as warranted: Qualifier Definition B Not detected substantially above the level reported in the laboratory or field blanks. R Unusable result. Analyte may or may not be present in the sample. J Analyte present. Reported value may not be accurate or precise. UJ Not detected. Reporting limit may not be accurate or precise. The Validation Status Code field is set to “DVM” if the ADQM DVM process has been performed. If the DVM has not been run, the field will be blank. If the DVM has been run (Validation Status Code equals “DVM”), use the Validation Qualifier.

The electronic data submitted for this project was reviewed via the Data Verification Module (DVM) process. Overall, the data is acceptable for use without qualification, except as noted on the attached DVM Narrative Report. The lab reports due to a large page count are stored on a network shared drive and are available to be posted on external shared drives, or on a flash drive. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF Data Verification Module (DVM) The DVM is an internal review process used by the ADQM group to assist with the determination of data usability. The electronic data deliverables received from the laboratory are loaded into the Locus EIM™ database and processed through a series of data quality checks, which are a combination of software (Locus EIM™ database Data Verification Module (DVM)) and manual reviewer evaluations. The data is evaluated against the following data usability checks: • Field and laboratory blank contamination • US EPA hold time criteria • Missing Quality Control (QC) samples • Matrix spike (MS)/matrix spike duplicate (MSD) recoveries and the relative percent differences (RPDs) between these spikes • Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • Difference/RPD between field duplicate sample pairs • RPD between laboratory replicates for inorganic analyses • Difference/percent difference between total and dissolved sample pairs There are two qualifier fields in EIM: Lab Qualifier is the qualifier assigned by the lab and may not reflect the usability of the data. This qualifier may have many different meanings and can vary between labs and over time within the same lab. Please refer to the laboratory report for a description of the lab qualifiers. As they are lab descriptors they are not to be used when evaluating the data. Validation Qualifier is the 3rd party formal validation qualifier if this was performed. Otherwise this field contains the qualifier resulting from the ADQM DVM review process. This qualifier assesses the usability of the data and may not equal the lab qualifier. The DVM applies the following data evaluation qualifiers to analysis results, as warranted: Qualifier Definition B Not detected substantially above the level reported in the laboratory or field blanks. R Unusable result. Analyte may or may not be present in the sample. J Analyte present. Reported value may not be accurate or precise. UJ Not detected. Reporting limit may not be accurate or precise. The Validation Status Code field is set to “DVM” if the ADQM DVM process has been performed. If the DVM has not been run, the field will be blank. If the DVM has been run (Validation Status Code equals “DVM”), use the Validation Qualifier. If the data has been validated by a third party, the field “Validated By” will be set to the validator (e.g., ESI for Environmental Standards, Inc.).

X ER# Description Other QA/QC Items to Note: * See DVM Narrative Report, Lab Report, and/or ER # for further details as indicated. The electronic data submitted for this project was reviewed via the Data Verification Module (DVM) process. Overall, the data is acceptable for use without qualification, except as noted on the attached DVM Narrative Report. The lab reports due to a large page count are stored on a network shared drive and are available to be posted on external shared drives, or on a flash drive. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF Data Verification Module (DVM) The DVM is an internal review process used by the ADQM group to assist with the determination of data usability. The electronic data deliverables received from the laboratory are loaded into the Locus EIM™ database and processed through a series of data quality checks, which are a combination of software (Locus EIM™ database Data Verification Module (DVM)) and manual reviewer evaluations. The data is evaluated against the following data usability checks: • Field and laboratory blank contamination • US EPA hold time criteria • Missing Quality Control (QC) samples • Matrix spike (MS)/matrix spike duplicate (MSD) recoveries and the relative percent differences (RPDs) between these spikes • Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • Difference/RPD between field duplicate sample pairs • RPD between laboratory replicates for inorganic analyses • Difference/percent difference between total and dissolved sample pairs There are two qualifier fields in EIM: Lab Qualifier is the qualifier assigned by the lab and may not reflect the usability of the data. This qualifier may have many different meanings and can vary between labs and over time within the same lab. Please refer to the laboratory report for a description of the lab qualifiers. As they are lab descriptors they are not to be used when evaluating the data. Validation Qualifier is the 3rd party formal validation qualifier if this was performed. Otherwise this field contains the qualifier resulting from the ADQM DVM review process. This qualifier assesses the usability of the data and may not equal the lab qualifier. The DVM applies the following data evaluation qualifiers to analysis results, as warranted: Qualifier Definition B Not detected substantially above the level reported in the laboratory or field blanks. R Unusable result. Analyte may or may not be present in the sample. J Analyte present. Reported value may not be accurate or precise. UJ Not detected. Reporting limit may not be accurate or precise. The Validation Status Code field is set to “DVM” if the ADQM DVM process has been performed. If the DVM has not been run, the field will be blank. If the DVM has been run (Validation Status Code equals “DVM”), use the Validation Qualifier. If the data has been validated by a third party, the field “Validated By” will be set to the validator (e.g., ESI for Environmental Standards, Inc.).

X ER# Description Other QA/QC Items to Note: * See DVM Narrative Report, Lab Report, and/or ER # for further details as indicated. The electronic data submitted for this project was reviewed via the Data Verification Module (DVM) process. Overall, the data is acceptable for use without qualification, except as noted on the attached DVM Narrative Report. The lab reports due to a large page count are stored on a network shared drive and are available to be posted on external shared drives, or on a flash drive. DocuSign Envelope ID: 9F06E5E5-B9D0-409B-8A8A-8D82E4596CEF Data Verification Module (DVM) The DVM is an internal review process used by the ADQM group to assist with the determination of data usability. The electronic data deliverables received from the laboratory are loaded into the Locus EIM™ database and processed through a series of data quality checks, which are a combination of software (Locus EIM™ database Data Verification Module (DVM)) and manual reviewer evaluations. The data is evaluated against the following data usability checks: • Field and laboratory blank contamination • US EPA hold time criteria • Missing Quality Control (QC) samples • Matrix spike (MS)/matrix spike duplicate (MSD) recoveries and the relative percent differences (RPDs) between these spikes • Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) recoveries and the RPD between these spikes • Surrogate spike recoveries for organic analyses • Difference/RPD between field duplicate sample pairs • RPD between laboratory replicates for inorganic analyses • Difference/percent difference between total and dissolved sample pairs There are two qualifier fields in EIM: Lab Qualifier is the qualifier assigned by the lab and may not reflect the usability of the data. This qualifier may have many different meanings and can vary between labs and over time within the same lab. Please refer to the laboratory report for a description of the lab qualifiers. As they are lab descriptors they are not to be used when evaluating the data. Validation Qualifier is the 3rd party formal validation qualifier if this was performed. Otherwise this field contains the qualifier resulting from the ADQM DVM review process. This qualifier assesses the usability of the data and may not equal the lab qualifier. The DVM applies the following data evaluation qualifiers to analysis results, as warranted: Qualifier Definition B Not detected substantially above the level reported in the laboratory or field blanks. R Unusable result. Analyte may or may not be present in the sample. J Analyte present. Reported value may not be accurate or precise. UJ Not detected. Reporting limit may not be accurate or precise. The Validation Status Code field is set to “DVM” if the ADQM DVM process has been performed. If the DVM has not been run, the field will be blank. If the DVM has been run (Validation Status Code equals “DVM”), use the Validation Qualifier. If the data has been validated by a third party, the field “Validated By” will be set to the validator (e.g., ESI for Environmental Standards, Inc.).
