Phase II ERD Injection and SVE Semi-Annual Monitoring Report Former Knitronics Facility 1515 W.Academy Street Cherryville,North Carolina NCD0002787 H&H Job No. MOH-014 1.0 Introduction Hart & Hickman, P.C. (H&H) prepared this Phase II Enhanced Reductive Dechlorination (ERD) and Soil Vapor Extraction (SVE) System Semi-Annual Monitoring Report on behalf of Mohican Mills, Inc. (Mohican) for the former Knitronics facility (NONCD0002787; BF #20051-16-036) located at 1515 W. Academy Street in Cherryville, North Carolina (hereafter referred to as the site). This report serves as a Remedial Action Progress Report (RAPR). A Site Location Map is provided as Figure 1. The general layout of the site, including buildings, pavement, and vegetation, is illustrated on the Site Map provided as Figure 2. This report has been prepared in accordance with a voluntary Administrative Agreement (AA) for a state-directed remedial action executed July 10, 2019, between the North Carolina Department of Environmental Quality (DEQ) Division of Waste Management Superfund Section and Mohican. In a letter dated March 9, 2018, the Division requested Mohican enter into the voluntary AA to perform the work necessary to develop and implement a remedial action program that focused on mitigating potential exposure risks and contaminant mass reduction. The signed and notarized DEQ Inactive Hazardous Sites Branch (IHSB) Report Certifications are provided in Appendix A. The Remedial Action Plan (RAP), submitted on June 12, 2020, included the results of remedial action pilot testing and the system designs for soil and groundwater remediation proposed for the site. Soil treatment via the SVE system was proposed to mitigate the potential for future vapor intrusion and leaching of contaminants to groundwater. The active groundwater remedy for the site is ERD in the source area. ERD injections were conducted to reduce contaminant mass in the groundwater source area such that natural attenuation can proceed for the non- 1 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Peport/Knitron hart hickman SMARTtR .. .•.'i r, ;i->I.ITI�1.S source/downgradient areas of the plume. Ultimately, as stated in the RAP, the goal of the contaminant mass reduction is to reduce source area soil and groundwater concentrations by an order of magnitude. The RAP was approved by DEQ in a letter dated July 24, 2020. SVE system installation activities were completed in general accordance with the RAP between August 2021 and January 2022. A summary of the SVE system installation activities is discussed in Section 5.0, and a detailed description of the SVE system installation activities is presented in H&H's Soil Vapor Extraction (SVE) System Construction Completion Report (CCR) dated June 29, 2022. From November 3, 2020 to November 21, 2020, H&H conducted Phase I ERD groundwater injection activities at the Site. The Phase I ERD event was performed by injecting Terra Systems, Inc. (TSI) SRS®-SD Small Droplet Emulsified Vegetable Oil (EVO) Substrate into 40 injection points near the former wastewater treatment basin. A total of approximately 825 gallons of SRS®-SD concentrate (mixed with approximately 8,250 gallons of potable water, TSI- DC, and sodium bicarbonate and calcium carbonate for pH buffering) were injected into the subsurface. A detailed description of the Phase I ERD injection activities is presented in H&H's Phase I ERD and First Quarterly Remedial Action Progress Report dated May 5, 2021. From September 19, 2022 to October 24, 2022, H&H conducted Phase II ERD groundwater injection activities at the site. The Phase II ERD event was performed by injecting TSI SRS®- SD Small Droplet EVO Substrate into 75 injection points within the eastern portion of the site warehouse building where the former dye house was located and areas between the former dye house and the former wastewater basin (Figure 3). An equipment layout schematic is shown on Figure 4. A total of approximately 1,590 gallons of SRS®-SD concentrate (mixed with approximately 15,900 gallons of potable water, TSI-DC, sodium bicarbonate, and calcium carbonate) was injected into the subsurface. A detailed description of the Phase II ERD injection activities and first semi-annual post-injection sampling event conducted in January 2023 is presented in H&H's Phase II ERD Injection and SVE Semi-Annual Monitoring Report dated April 28, 2023. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. This report includes a summary of the second semi-annual post-injection sampling event conducted in July 2024. Additionally, the report presents operation and maintenance (O&M) activities and off-gas sampling results for the SVE system for the latest period of operation. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 2.0 Site Background Information 2.1 Site Location The subject site is a former textile dyeing and finishing facility located on the property currently owned by Mohican Mills, Inc. via merger with Travis Knits, Inc. The property is located at 1515 W. Academy Street, in Cherryville, North Carolina (Figure 1). The facility warehouse building is on a parcel approximately 12.13 acres in size (Figure 2). An adjacent parcel, also owned by Mohican Mills, Inc, contains 4.64 acres consists of undeveloped wooded land to the east of the facility building. Currently, the warehouse building (referred to as the Site building) is occupied by Tire Cord USA and its affiliate Carolina-Pacific Fibers, LLC which are leasing the building for warehouse space. The approximate coordinates of the site are 35' 22' 9.44"N latitude and - 81° 24' 7.13"W longitude. The DEQ Inactive Hazardous Sites Branch (IHSB) reference number for the Site is NCD0002787. 2.2 Land Usage and Zoning The land use in the vicinity of the Site is primarily residential. Properties located to the west and south are generally residential while properties to the north and east are generally undeveloped. The site and properties to the north are zoned General Manufacturing and Commercial (GMC); and properties to the west, south and east are zoned Residential (R-9, R-19, and R-40). The land surrounding the site in a half-mile radius is a mixture of undeveloped, residential, commercial and industrial properties. The surrounding properties include the following: • North — West Academy Street with undeveloped wooded land and mix of land uses including residential beyond. • South—Residential properties and undeveloped land. • East — Undeveloped wooded land with a Pre-Regulatory Landfill known as Westgate Park Landfill (NONCD0000817); residential properties; and commercial properties beyond. • West—An industrial property with Paul H Beam Road and residential properties beyond. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican ican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual t h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 2.3 Operational History A description of the Site operational history and owners is included in the RAP. Briefly, the Site was formerly operated as textile dyeing and finishing facility with warehouse storage by third parties. The Site was last operated as a textile facility in 2001 and was sold in 2005 to Mohican Mills as part of an asset transaction. Mohican Mills has used the Site for storage and warehousing. A common compound associated with certain former textile dyeing and finishing operations is the chlorinated volatile organic compound (VOC) tetrachloroethene (PCE). As summarized in the RAP,previous remedial investigations indicated that widespread PCE impacts were present in soil above the DEQ Protection of Groundwater Preliminary Soil Remediation Goals (PSRGs) and in groundwater above the 2L Standard. The source area is mostly underneath the east side of the Site building and in the area of the former wastewater pre- treatment pit to the east of the Site building. 2.4 Area Water Supply Wells As described in prior reports, water supply wells are located in the area. However, there are no water supply wells downgradient of the plume and municipal water is available on W. Academy St. In addition, upgradient and cross-gradient water supply wells were tested multiple times over several years by H&H and NC DEQ. A deeper monitoring well (MW-2D) between the source area and the nearest water supply well did not contain impacts above the 2L Groundwater Standards based on September 2024 data. Based on the lack of VOC compound detections in the water supply wells, reduction in groundwater PCE concentrations, the lack of downgradient water supply wells relative to the plume, and recent data for MW-213, the potential for Site groundwater to impact water supply wells appears to be low. Following submittal of H&H's Phase II ERD Injection and SVE Semi-Annual Report dated November 6, 2023, DEQ approved cessation of routine monitoring of water supply wells while noting that concentration trends should be monitored in that aforementioned monitoring well MW-21). https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 2.5 Geology and Hydrogeology The geology below the site consists of three layers: the saprolite zone, the partially weathered rock (PWR) zone, and the bedrock zone. These geologic layers are interconnected and no confining units are present. The saprolite consists of unconsolidated clay, silt, and sand with lesser amounts of rock fragments. Due to the range of parent rock types and their variable susceptibility to weathering, the saprolite ranges widely in color, texture, and thickness. The PWR zone, also termed the transition zone, contains highly weathered bedrock that is typically characterized as a zone of high permeability. The bedrock zone is competent but fractured parent rock. In the site area, underlying bedrock is composed of metamorphic rock consisting mainly of mica schist. Soils encountered at the site generally consist of red/brown to tan sandy silt to approximately 55 to 89 ft below ground surface (bgs). PWR, as determined by auger refusal, was encountered at a depth of 55 to 89 ft bgs. Competent bedrock was not encountered during Phase I and II RI assessment activities, but it is likely present just below the PWR zone. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 3.0 Groundwater Performance Sampling 3.1 Semi-Annual Post Injection Performance Monitoring Based on the amount of groundwater data collected to date, ERD is effectively treating the groundwater PCE plume. Therefore, semi-annual post-injection performance monitoring is being conducted instead of quarterly monitoring as proposed in the RAP. Historical groundwater elevation measurements, data, and natural attenuation data are presented in Tables 1, 2 and 3, respectively. A matrix summarizing the injection performance monitoring is provided as Table 4. During the fourth post-injection semi-annual sampling event conducted on July 16 and July 17, 2024, groundwater samples were collected from MW-1, MW-2S, MW-2D, MW-3S, MW-3D, MW-4S, MW-4D, MW-5S, MW-5D, MW-6S, MW-7S, MW-8S, MW-9S, MW-IOS, MW-11S, and MW-11D. The wells were purged utilizing a decontaminated bladder pump with dedicated polyethylene tubing and low flow/low stress techniques. Field measurements, including DO, ORP, pH, specific conductivity, ferrous iron, and temperature, were recorded during purging activities at each of the monitoring well locations. Groundwater samples were submitted to Waypoint Analytical, a North Carolina certified laboratory, for analysis of contaminants of concern (COC) VOCs by EPA Method 8260 and the natural attenuation parameter total organic carbon (TOC). For quality assurance purposes, one duplicate sample and one trip blank were also submitted for analysis of COC VOCs by EPA Method 8260. H&H instructed the laboratory to report J-values. Monitoring wells MW-3S, MW-4S, MW-4D, MW-5S, MW-5D, MW-6S, MW-7S, MW-9S, MW-IOS, MW-I IS, and MW-I ID were also analyzed for dissolved gases (methane, ethene, and ethane) using RSK 175 and Resource Conservation and Recovery Act (RCRA) metals. The dissolved gas analysis is primarily to check for ethene which provides evidence of complete PCE reduction while the metals analysis is to check for metal solubilization due to changes in aquifer geochemistry potentially related to the injection. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. Because of a slightly elevated PCE detection limit (<2.2 µg/L) in MW-21) in the July 2024 data, H&H resampled this well in September 2024. The PCE detection limit for the September 2024 sample from MW-21)was improved and below the 2L Standard. Groundwater sample results are summarized on Table 2, and groundwater field parameters are summarized in Table 3. The low-flow groundwater sampling records are included in Appendix B, and groundwater laboratory reports and chain-of-custody forms are included in Appendix C. 3.1.1 Groundwater Levels Groundwater levels in the monitoring well network were gauged using an electronic water level meter on July 16 and 17, 2024 (Table 1). The estimated potentiometric surface maps for the shallow (saprolite) and deeper (bedrock) aquifers for the July 2024 groundwater elevation data are presented in Figures 5 and 6, respectively. The groundwater flow directions in the shallow and deeper aquifers are generally to the east or east-southeast toward an unnamed tributary of Muddy Fork Creek located approximately 700 ft southeast of the southeast corner of the site. This flow direction is generally consistent with prior data. 3.1.2 VOCs The July 2024 groundwater sampling results indicate that VOCs remain in groundwater above 2L groundwater standards. PCE was the parent chlorinated solvent in groundwater prior to the ERD injections, and PCE concentrations have been greatly reduced by the injections. The maximum PCE concentration detected during the July 2024 sampling event was 36,000 µg/L in source area well MW-3S. This PCE concentration compares to a pre-injection concentration of 190,000 µg/L in MW-3S in 2019. In other source area wells (MW-6S, MW-9S, MW-10S, MW- 11S, and MW-11D), PCE concentrations varied compared to the January 2024 semi-annual sampling event. However, in general, PCE concentrations have been significantly reduced over time by the ERD injections. For example, the PCE concentration in MW-9S in July 2024 was 208 µg/L compared to a pre-injection maximum of 140,000 µg/L in 2019. For wells located outside of the ERD injection areas and comparing July 2023 and July or September 2024 data, there was a continued reduction in the PCE concentrations in monitoring https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. wells MW-2D, MW-4S, MW-5S and MW-5D and slight increases in PCE concentrations in wells MW-3D and MW-4D. The reduction of PCE concentrations in select wells located outside of the injection areas is most likely associated with source area mass reduction resulting from the SVE system and Phase I and 11 ERD injection events. The ERD degradation products trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE), vinyl chloride (VC), and ethene generally increased in injection area wells following the ERD injections. In July 2024, TCE concentrations (up to 28,800 µg/L; MW-3S), cis-1,2-DCE concentrations (up to 37,800 µg/L; MW-3S); and VC concentrations (up to 2,690 µg/L) in MW- 9S remain. However, while daughter products concentrations are particularly elevated in MW- 3S and MW-9S, ethene concentrations increased in these same two wells comparing July 2023 and July 2024 data. The continued increase of PCE degradation products (TCE, cis-1,2-DCE, VC, and ethene) following the Phase II ERD injection indicates progression in the PCE reductive dechlorination process to the desired end point which is ethene. These trends indicate that the ERD injections are resulting in enhanced bioremediation in the injection area. Groundwater PCE concentrations detected in the shallow and deeper monitoring wells are shown on Figures 7 and 8. Concentrations of PCE, TCE, cis-1,2-DCE, and VC detected in the shallow source area monitoring wells are shown on Figure 9. The reduction of shallow groundwater PCE concentrations between October 2020 and July 2024 is shown on Figure 10. Graphs depicting the PCE, TCE, cis-1,2-DCE, and VC trends in source area monitoring wells along with the timing of the ERD injection events are included in Appendix D. 3.1.3 RCRA Metals To check for metal concentration changes due to potential changes in geochemistry related to the injection, H&H is monitoring metals in groundwater in accordance with the injection permit. Low concentrations of RCRA metals were detected in July 2024 (Table 2). Only the concentration of arsenic in MW-11S (18.6 µg/L) exceeded its respective 2L Groundwater Standard of 10 µg/L. Turbidity (191 NTUs) is also elevated in MW-11 S which is the likely reason for the elevated arsenic in that well. No metals were detected in downgradient monitoring https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. wells above 2L Groundwater Standards. Metals concentrations will continue to be monitored in the site wells during future post-injection groundwater sampling events. 3.2 Geochemical Parameters A discussion of the field measurements collected for certain natural attenuation parameters and geochemical laboratory results from the July 2024 post-injection sampling event is presented below. Field measurements and laboratory results of the geochemical analyses are summarized in Table 3, and the laboratory analytical reports are provided in Appendix C. 3.2.1 TOC Because TOC is utilized as an electron donor in the reductive dechlorination process, TOC concentrations provide an indication of the presence and sustainability of the substrate injection. The presence of TOC at concentrations greater than 20 mg/L is considered ideal for biodegradation of chlorinated solvents. During the first monitoring event following the Phase II ERD injection, TOC concentrations were detected above 20 mg/L in MW-3S, MW-9S, MW- IOS, and MW-IIS and have generally remained above 20 mg/L in these wells since the injection. For the July 2024 sampling event, TOC concentrations exceeded 20 mg/L in MW- 3S, MW-9S, and MW-I IS. The available TOC in the injection area shallow wells continues to be favorable for facilitating reductive dechlorination. 3.2.2 Methane The presence of methane indicates anaerobic microbial degradation (methanogenesis) is occurring and reducing conditions have been established which are favorable for reductive dechlorination. Methane concentrations increased in monitoring wells MW-3S, MW-9S, MW- 1 OS, MW-I I S, and MW-I I D between the baseline sampling event in November 2021 and the post-injection sampling event in January 2023. Elevated methane levels remain in these same six source area monitoring wells in July 2024. These concentrations indicate that strongly reducing conditions have been established in shallow groundwater in the injection area. 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 3.2.3 Ethane and Ethene The dissolved gases ethene and ethane are the non-toxic end products of reductive dechlorination of chlorinated solvents, and their presence indicates the complete degradation of chlorinated solvents. For PCE, the end product of reductive dechlorination is ethene. Ethene was detected in MW-3S (369 µg/L), MW-9S (2,380 µg/L), MW-10S (352 µg/L), and MW-11S (31.2 µg/L) in July 2024. These concentrations provide evidence of complete degradation of a portion of the PCE in groundwater in the injection area. 3.2.4 Natural Attenuation Field Measurements Dissolved Oxygen (DO) DO is used by microbes as an electron acceptor for the biodegradation of organic carbon. Reductive dechlorination occurs under anaerobic or low DO conditions. DO concentrations of less than 1 mg/L are favorable for ERD. For the July 2024 dataset, DO measurements ranged from 0.04 mg/L to 6.35 mg/L in injection area wells MW-3S, MW-6S, MW-9S, MW-10S, MW-11S, and MW-11D during the July 2023 post-injection sampling event. Other than low dissolved oxygen levels in MW-3S and MW-10S, the dissolved oxygen levels exceeded 1 mg/L. However, other parameters such as ORP, ferrous iron and methane indicate reducing conditions in these source area monitoring wells. pH and Temperature Groundwater pH values ranging from 6 to 8.5 standard units are generally preferable for anaerobic biodegradation. The pH of groundwater affects the presence and activity of microbial populations. Acid generated during reductive dechlorination can decrease pH levels after a bioenhancement injection. The pH ranged from 5.30 to 6.53 in the injection area wells in July 2024. Certain pH values are below the range considered favorable for reductive dechlorination. The low pH levels in groundwater may limit anaerobic biodegradation processes at the site. The low pH levels are due to naturally occurring conditions and the acids produced by reductive dechlorination process. Temperature does not greatly influence reductive dechlorination, but temperatures greater than 20 C may accelerate biochemical processes. Temperatures ranged from 18.5 C to 21.8 C in the https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. injection area wells in July 2024. These temperatures are in the range which is considered acceptable for biodegradation. ORP The ORP of groundwater is a measure of electron activity and is an indicator of the relative tendency of a solution to accept or transfer electrons. ORP of a groundwater system affects biodegradation rates. Reductive dechlorination is most efficient in the ORP range corresponding to sulfate reduction and methanogenesis (<-100 mV), but reductive dechlorination also occurs in the ORP range associated with nitrate, manganese, and iron reduction (-50 mV to 740 mV). ORP ranged from -164.3 mV to 374.5 mV in the injection area wells during the July 2024 sampling event. With the exception of the relatively high ORP in MW-6S, the ORP data were negative indicating reducing conditions favorable for reductive dechlorination. Ferrous Iron H&H used a Hach field test kit to measure ferrous iron. Ferrous iron was detected in four of the six injection area monitoring wells. The presence of ferrous iron indicates reducing conditions which is favorable for reductive dechlorination. 3.3 Quality Control For quality assurance purposes, one duplicate sample (taken at MW-3S) and a laboratory- prepared trip blank were submitted for analysis of COC VOCs by EPA Method 8260 for the July 2024 sampling event. The duplicate sample contained similar concentrations to the parent sample particularly for PCE and PCE degradation products. The trip blank did not contain detectable concentrations of target VOCs other than a trace level of acetone which is a common laboratory-introduced contaminant. The quality control data indicate that the data collected are suitable for their intended use. Duplicate sample results are summarized in Table 2. 12 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 3.4 Investigation Derived Waste Due to elevated compound concentrations near the source area, purge water generated during the July 2024 sampling event from source area monitoring wells was containerized in a 55-gallon drum. The drum is approximately 1/2 full and is staged on-site near the remediation building for additional use. 13 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 4.0 SVE System Operation The SVE system construction was completed in January 2022 with system start-up beginning on January 12, 2022. The SVE system is split into four well fields: Fields A, B, C, and D. Fields A and B pull air from under the eastern portion of the building. Two SVE wells are located on each well field. Field A consists of SVE-1 and SVE-2; Field B consists of SVE-3 and SVE-4; Field C consists of SVE-5 and SVE-6; and Field D consists of SVE-7 and SVE-8. The piping for each well field extends from the SVE building then splits into individual headers that run to each well. The total depth and screen interval for each SVE well is listed in the table below, and the SVE well locations and final SVE piping layout are shown on Figure 11. SVE Well Well Total Depth Screen Interval ftb s ftb s SVE-1 30 10—30 SVE-2 30 10—30 SVE-3 30 10—30 SVE-4 30 10—30 SVE-5 25 10—25 SVE-6 25 10—25 SVE-7 23 10—23 SVE-8 23 10—23 The well fields are manifolded to an Ametek Rotron® 20 horsepower (hp) explosion-proof regenerative blower. An air/water separator precedes the blower to remove particulates and water from the extracted air. Due to the potential for contaminant concentrations within the condensate water, the air/water separator contains a manually controlled ball valve and flexible piping to discharge the accumulated liquids into two separate 55-gallon drums equipped with level gauges and stored on a 66-gallon secondary containment pallet within the SVE building. The SVE system building as-built diagram is included as Figure 12. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects 4 an Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I ha rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. Due to the proximity of the remediation building and SVE off-gas discharge to the Site building (approximately 120 ft), SVE system controls are designed to prevent discharged vapors from reaching the Site building based on ambient wind direction and speed. 4.1 SVE System Performance System O&M activities include regular site visits by H&H personnel to maintain the SVE equipment, improve performance, and for incidental troubleshooting. In addition, H&H periodically checks on system operation via remote online access. System operating parameters are adjusted as necessary to maintain the desired system performance. During the period of system operation between April 2024 and September 2024, the SVE system continued to operate with only brief shut-downs. During each monthly O&M visit, the air/water separator is observed for accumulation of water and is manually drained as necessary into a storage drum. Once full, the storage drum water will be sampled for characterization,profiled, and properly disposed at a permitted facility. Key SVE parameter data since system start-up are summarized on Table 5, and prior individual wellhead SVE data are included on Table 6. A brief summary and evaluation of the main parameters, including SVE vacuum levels, flow rates, and off-gas vapor concentrations are presented below. SVE Vacuum Vacuum levels have been maintained at approximately 52 to 55 in-WC at the distribution piping headers. This vacuum allows for the blower temperature to remain within the blower operational range without dilution air. The data indicate that only minimal vacuum loss is occurring through the system equipment and piping. SVE Flow Rates SVE air flow rates measured with the flow meter at the equipment building have ranged from approximately 160 standard cubic feet per minute (scfm) to 234 scfm during the current 15 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. reporting period with the dilution air valve closed and the blower set to approximately 55 to 58 in-WC vacuum. The individual well field flow data indicate that the largest portion of the total air flow is coming from Field A, which contains the highest PCE concentrations as mentioned below. The smallest portion of the total air flow is coming from Field B. SVE Vapor Concentrations During each O&M visit, SVE system off-gas discharge concentrations are measured using a photoionization detector (PID) from each of the four well fields (Table 5). The data for the current reporting period indicated that the highest vapor concentrations were present in Field A, with Field D exhibiting the lowest vapor concentrations. A sample of the off-gas discharge vapor was collected on August 6, 2024 for laboratory analysis of VOCs by EPA Method TO-15. The analytical off-gas samples were collected using a 1-Liter Tedlar bag connected to the off-gas discharge. After collection, the bag was sealed per standard procedures and shipped under chain-of-custody record to Eurofins, a North-Carolina certified laboratory. A summary of the TO-15 analytical results is included on Table 7, and the analytical laboratory report is included in Appendix C. The analytical data indicate PCE in the SVE off-gas at a concentration of 420,000 micrograms per cubic meter(µg/m3). The concentration is greatly reduced compared to the start-up PCE off- gas concentration of 8,500,000 µg/m3. No other constituents in the off-gas samples were detected above laboratory reporting limits, potentially due to elevated laboratory reporting limits of other compounds as a result of the elevated PCE concentrations. The data indicate that PCE is the primary contaminant being removed by the SVE system, which is consistent with soil and groundwater data. However, other contaminants at lower concentrations are likely also being removed. The data also indicate that off-gas concentrations are declining as mass is removed from the vadose zone. A graph depicting the PCE concentrations over time is included in Appendix E. 16 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 4.2 SVE Mass Removal Contaminant mass removal has been calculated using the TO-15 laboratory analytical results (Table 8) and average flow rates for each O&M visit. Note, for visits where TO-15 samples were not collected, an assumed concentration of PCE was used based on the concentration of the previous TO-15 sample. In addition, the discharge flow rate over the specific period between O&M visits was assumed to be consistent between visits. Using the mass removal calculations for the time from start-up (January 12, 2022) to September 11, 2024, approximately 33,989 lbs of PCE (equivalent to approximately 2,518 gallons) have been removed by the SVE system. The estimated September 2024 removal rate is 8.8 lbs/day. As stated above, additional mass removal from other compounds is likely also occurring. Graphs depicting mass removal for PCE overtime and cumulative mass removal are included in Appendix E. 4.3 Ambient Air Testing As discussed in the SVE System CCR dated June 29, 2022, the ambient air within typical breathing space (approximately 5-ft above ground surface) was monitored during system startup and several months thereafter under various wind conditions based on the wind vane anemometer data at the discharge stack and using a hand-held PID capable of reading VOC concentrations in vapor in the parts per billion by volume (ppbv) range. The ambient air monitoring generally included recording measurements from between 50 feet to 200 feet from the discharge stack in the cardinal directions. Several additional locations were measured near the Site Building. The prior ambient air monitoring data are summarized on Table 9, and the locations where measurements were collected are depicted on Figure 11. Evaluation of the prior ambient air monitoring and the wind speed and direction in the area of the discharge stack indicate the Site building is upwind or crosswind the majority of the time and that most downwind locations did not exhibit detectable levels of VOC vapor concentrations 17 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. during operation of the SVE system. Because off-gas discharge mass concentrations are decreasing and the risk of increased VOC concentrations at the building envelop has diminished, ambient air monitoring was discontinued in May 2022. 18 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. 5.0 Remediation Status Summary and Recommendations Based on the laboratory analytical results for groundwater samples collected during the four semi-annual post-injection sampling events, including the most recent data from July 2024, significant reductions in concentrations of PCE were observed in injection area wells since implementation of the Phase II ERD remedial actions. Additionally, concentrations of the degradation products TCE, cis-1,2-DCE, trans-1,2-DCE, and VC increased in monitoring wells near the injection area following the injection. Ethene is also present which is indicative that the reductive dechlorination process is proceeding fully to the desired end point. Geochemical conditions are generally conducive to continued reductive dechlorination in the source area. As noted in the DEQ-approved RAP, the purpose of the groundwater remedial action was to reduce contaminant mass in the source area such that natural attenuation can proceed for the non- source/downgradient areas of the plume. The specific goal of the contaminant mass reduction was to reduce source area concentrations by an order of magnitude. As noted below, the PCE concentrations in shallow source area monitoring wells have in essence been reduced by an order of magnitude. Comparison of RAP Baseline Groundwater Event (2019) and Current Data (Jul 2024) for PCE in Shallow Source Area Monitoring Wells PCE Concentration Order of Source Area Baseline (Jan Current (Jul Magnitude Monitoring Well or Sept 2019) 2024) % Reduction Reduction MW-3S 87,000 36,000 59 90 MW-6S 14,000 47 100 90 MW-9S 140,000 208 100 90 MW-10S 18,000 4,070 77 1 90 MW-11S 22,000 1.38 100 90 Average 87 90 Based on the remedial efforts to date, which included a pilot test and two phases of ERD injections, and the above results, H&H is not proposing to conduct additional injections. 19 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I ha rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`. However, H&H is proposing to continue groundwater performance monitoring on an annual basis with slight reductions to the sampling for upgradient wells MW-1 and MW-7S and cross- gradient well MW-8S. Based on the long groundwater monitoring history, H&H is proposing the following changes which will be implemented with the annual sampling event in July 2025 (Table 4): • discontinue analysis of VOCs and TOC in MW-1 • discontinue analysis of TOC, dissolved gases, and RCRA metals in MW-7S • discontinue analysis of TOC and dissolved gases in MW-8S In accordance with the DEQ-approved RAP, an SVE system was installed to mitigate on-going contaminant contributions to groundwater via leaching from the overlying soil and to reduce the VOC mass that may contribute to vapor intrusion. The SVE system was started up on January 17, 2022 and has removed approximately 33,989 lbs of PCE (approximately 2,518 gallons). As noted below, the PCE concentrations in SVE off-gas have been reduced by more than an order of magnitude. In addition, significant rebounding did not occur when the SVE system was shut down for a period of time in October 2023 (Appendix E). Comparison of PCE Off-Gas Reduction (Jan 2022) and Current Data (Aug 2024) Order of SVE Off-Gas Results Magnitude by TO-15 Baseline (Jan 2022) Current (Aug 2024) % Reduction Reduction PCE in Off-Gas 8,500,000 420,000 95 90 Based on the soil remedial efforts to date and the above results, H&H is proposing to discontinue use of the SVE system. 20 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual(h art : h i c k I 1 1 an SMARTER kwiRONMENGI SOLUTION`. 6.0 Schedule Monitoring reports have been submitted semi-annually for two years following the Phase II ERD injection. Based on the results described herein, the frequency of groundwater sampling will now be annually in approximately July. The plan to convert to annual sampling was previously described in the UIC permit application dated August 17, 2022 as approved by UIC Permit #WI0300476 dated August 19, 2022. Each annual report will be submitted within approximately 90 days of the annual sampling event. Reports will include groundwater data, copies of laboratory analytical data, summary tables, figures, and other information. A Final Project Evaluation (FPE) for the UIC permit is to be submitted within nine months of completing injection activities or an interim evaluation will be submitted with a permit renewal application. The final report or interim evaluation will include historical monitoring data, and updated groundwater plume and potentiometric surface maps. The need for either a FPE or interim report will be decided prior to the UIC permit expiration date of July 31, 2027. 21 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-015 Knitronics 2024/Report/Knitronics Annual I h a rt : h i c k m a n SMARTER kwiRONMENGI SOLUTION`.

Receipt Exceptions The following sample was received in air sample bags: SVE-052924(140-36926-1). EPA Methods TO-14A and TO-15 describe the use of canisters for sampling and analysis,therefore,the use of air sample bags constitutes a modification to the method. The Field Sampler was not listed on the Chain of Custody. Air-GC/MS VOA Methods TO 15 LL, TO-14A, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air"as the blank reagent for canister cleaning, instrument calibration and sample analysis. Ultra-high purity humidified nitrogen from a cryogenic reservoir is used in place of"zero air" by Eurofins TestAmerica Knoxville. Method Air Transfer: The following sample was received in air sample bags: SVE-052924(140-36926-1).

Receipt Exceptions The Field Sampler was not listed on the Chain of Custody. Air-GC/MS VOA Methods TO 15 LL, TO-14A, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air"as the blank reagent for canister cleaning, instrument calibration and sample analysis. Ultra-high purity humidified nitrogen from a cryogenic reservoir is used in place of"zero air" by Eurofins TestAmerica Knoxville. Method TO-15: The continuing calibration verification (CCV)associated with batch 140-89634 exhibited %difference of>30%for C the following analyte(s): 1,3,5-Tri methyl benzene and Isopropyl alcohol; however,the results were within the LCS acceptance limits. The EPA method requires that all target analytes in the continuing calibration verification standard be within 30%difference from the initial calibration. According to the laboratory standard operating procedure,the continuing calibration is acceptable if it meets the laboratory control sample acceptance criteria. Method TO-15: The following analyte(s)recovered outside control limits for the LCS associated with analytical batch 140-89634: 1,3,5-Tri methyl benzene. This is not indicative of a systematic control problem because this was random marginal exceedance. Qualified results have been reported. Method Air Transfer: The following sample was received in air sample bags: SVE-080624(140-37931-1). In order to extend the holding times,this sample was transferred from the air sample bags into a Summa canister. No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
