As part of the CLRS Permit, this CSA is to be completed within 2 years following the issuance of the final permit. This CSA includes the items identified in 15A NCAC 02L .0106(g) and "I" Schedules of the CLRS Permit. This CSA was developed by EHS Support in concert with ONE Environmental of Carolina, PLLC ("ONE") as necessary to provide the Professional Engineer (P.E.) certification of the CSA as required by Section I — Schedules of the Permit. The area of interest for this CSA is the former CLRS lined pond that was taken out of service in 2011 and obtained final closure in November 2019 (EHS Support, 2020). This area is herein referred to as the "Site" and is provided on the topographic location map (Figure 1) which provides the outline and location of the Bakelite Acme Facility and the Site. The Site is also shown on Figure 2 to present the location in relation to the Bakelite Acme Facility. The current site conditions are presented as Figure 3. 1.1 Purpose and Objectives On July 29, 2021, the North Carolina Department of Environmental Quality (NCDEQ) issued a revised CLRS Permit WQ0034775 based on change of ownership of the Facility to Bakelite. Several existing conditions to the Permit were removed because the lined pond was closed, and the following two new conditions were added to the Permit: • Condition 1.1— Within 24 months of Permit issuance, the Permittee shall submit a CSA addressing the cause, significance, and extent of groundwater contamination in accordance with 15 A NCAC 02L.0106(g). Condition 1.2 — Upon approval of the CSA, the Permittee may be required to prepare and submit a Corrective Action Plan (CAP) for restoration of groundwater quality in accordance with 15 A NCAC 02L.0106(h). The following objectives were identified for this CSA in accordance with 15A NCAC 02L .0106 Corrective Action (paragraphs "d" and "g") to satisfy condition 1.1 of the permit: 1. Review historical reports and data for soil, sediment, sediment porewater, surface water, and groundwater data collected for the Acme, North Carolina Facility, and associated Wright Chemical Superfund Site to determine the source and cause of contamination. 2. Identify hazards to the public health and safety, and receptors and significant exposure pathways. 3. Determine the current groundwater conditions surrounding the CLRS. 4. Identify potential data gaps to characterize the horizontal and vertical extent of soil and groundwater contaminants and significant factors affecting contaminant transport. 5. Identify geological and hydrogeological features influencing the movement, chemical, and physical character of the contaminants. 6. Demonstrate that natural attenuation is occurring at the Site and that groundwater contaminants will not exceed the Permit standards at a compliance boundary. EHS Support LLC Comprehensive Site Assessment — Bakelite Acme Introduction 1.2 Site Background k7 The Acme Facility (owned and operated by Bakelite) is an active facility specializing primarily in the production of formaldehyde, aqua ammonia, and hexamine. The Site is the former CLRS lined pond area in the northwest corner of the Facility that was associated with the CLRS (Figure 2 and Figure 3). The Acme Facility is within the footprint of a United States Environmental Protection Agency (USEPA) led Superfund Site (Wright Chemical Corporation Superfund Site) (Figure 2). The former lined pond was regulated under the NCDEQ Division of Water Quality (DWQ) CLRS Permit number WQ0034775, issued to Momentive (d.b.a. Hexion) on November 30, 2010 (NCDENR, 2010). The current Permit issued in July 2021 was updated based on the change in ownership and the closure of the lined pond. Water (including stormwater first flush) previously generated from plant operations was discharged to the former lined pond as a historical practice. As allowed by the Permit, Bakelite operates three cooling towers (CT-3, CT-5, and CT-6) to support the manufacturing process, with the lined pond historically being both the source of the cooling tower make-up water and the discharge location of the cooling tower blowdown. Over time, the lined pond accumulated sludge, as indicated in the sludge surveys conducted in April 2009 and February 2010 (Arcadis, 2012). In 2010, Hexion installed two groundwater monitoring wells per NCDEQ DWQ CLRS Permit number WQ0034775CLRP. The locations of these monitoring wells are shown on Figure 2 and Figure 3. The monitoring wells, located northwest (WWMW-1) and southwest (WWMW-2), are sampled triennially (three times per year) and analyzed for pH, total dissolved solids (TDS), total sulfate (as SO4), total ammonia nitrogen (as N), total nitrate nitrogen (as N), volatile organic compounds (VOCs), total organic carbon (TOC), and methanal (formaldehyde) whole water. Groundwater monitoring has continued at the two monitoring wells after the lined pond was taken out of service. As part of this CSA, a third monitoring well (WWMW-3) was installed southeast of the former lined pond on July 7, 2022 (Figure 2 and Figure 3). This monitoring well was added to the triennial monitoring program and groundwater samples from all three wells were analyzed for the Permit required parameters and three additional CSA parameters (sulfide, dissolved iron, and dissolved manganese). 1.3 CLRS Pond Closure The CLRS lined pond was placed into service in the early 1990s (J.M. Waller Associates, Inc., 2012) in support of the prior owner's operations. Hexion (formerly d.b.a. Momentive Specialty Chemicals, Inc. ["Momentive"]) acquired this Site in 2006 and continued to operate the lined pond in a similar manner to the prior operations. Hexion took the lined pond out of service and initiated pre -characterization activities in July 2011. Initial cleaning of the lined pond started on July 26, 2011, and finished by the end of October 2011. After the sludge removal was complete the liner was inspected, and it was determined the liner was not repairable and the lined pond remained out of service since 2011. Final closure activities for the former lined pond were implemented by Hexion in 2019. The final closure activities consisted of liner removal, localized over -excavation beneath the liner, berm removal, and regrading to support positive drainage and placement of a vegetative layer, and were completed in November 2019. Following final closure, a three-year groundwater compliance monitoring program was implemented to assess the ongoing attenuation of Site -related constituents of potential concern (COPCs) in groundwater (EHS Support, 2020). Additional details of the lined pond closure are presented in the Lined Pond Closure Completion Report (EHS Support, 2020). EHS Support LLC Comprehensive Site Assessment — Bakelite Acme Introduction 1.4 Report Organization �7 As required by the Permit, this CSA was prepared to describe and include the items listed in 15A NCAC 02L .0106(g) and "I" Schedules of the draft CLRS Permit (Section 1.1). The CSA includes a summary of assessment activities and sampling results, a tabulated summary of field and laboratory data. The CSA also includes scaled figures showing sample locations, potentiometric surface maps, geochemical analyses, and example model parameters. Following this introductory section, the CSA consists of the following sections: • Section 2 — Assessment Activities: Summarizes the assessment activities conducted to meet the requirements of the CSA. • Section 3 — Hydrogeological Framework: Summarizes the groundwater contaminants and hydrogeology of the Site. • Section 4 — Geochemical Evaluation: Provides a summary of geochemical evaluation conducted as part of the CSA using data collected and Remedial Investigation (RI) data. • Section 5 — Compliance Boundary Demonstration: Summarizes the application of BIOSCREEN and BIOCHLOR models to demonstrate that that groundwater contaminants will not exceed the Permit standards at the compliance boundary. • Section 6 — Summary and Conclusions: Summarizes the assessment and evaluations completed as part of the CSA and conclusions following the findings of the CSA. • Section 7 — References: Provides a list of reference materials used in the preparation of the CSA. EHS Support LLC Comprehensive Site Assessment —Bakelite Acme L14h.4--ol-R Assessment Activities 2 Assessment Activities The following activities were conducted to prepare the CSA in accordance with 15A NCAC 02L .0106 Corrective Action (paragraphs "d" and "g"): • Historical report and data review for soil, sediment, sediment porewater, surface water, and groundwater data collected for the Acme, North Carolina Facility, and associated Wright Chemical Superfund Site for source, hazards to the public health and safety, and receptors and significant exposure pathways. • A baseline groundwater monitoring event to determine the current groundwater conditions surrounding the Site and compare groundwater sampling methods. • Data gap assessment to identify potential data gaps in the characterization of the horizontal and vertical extent of soil and groundwater contaminants. • Demonstration that groundwater contaminants will not exceed the permit standards at the compliance boundary (Mill Creek). • Geochemical evaluation to assess the concentrations and source of constituents of potential concern (COPC) in groundwater. 2.1 Historical Report and Data Review A comprehensive review of historical reports and data for the Acme Facility and Wright Chemical Superfund Site surrounding the former lined pond was conducted to identify potential data gaps in the Site characterization. Historical soil, groundwater, pore water, and surface water investigation findings were reviewed for historical concentrations of Site COPCs. In addition, historical laboratory results for the two groundwater monitoring wells (WWMW-1 and WWMW-2) were reviewed to evaluate COPC trends and permit standard exceedances. 2.2 Baseline Groundwater Sampling Event Following the historical report and data review for potential data gaps and historical concentrations of COPCs, a baseline groundwater sampling event was conducted to determine the current groundwater concentrations. Two monitoring wells (WWMW-1 and WWMW-2) were redeveloped to remove any potential sediment or solids from the well casing and sampled approximately 24 hours later using low - flow groundwater sampling techniques. The groundwater samples were analyzed for the constituents required by the 2021 Permit and compared to the typical triennial sampling results which were collected approximately one day following low -flow sampling. The triennial samples are collected by bailing three well volumes, allowing the well to recharge, and returning the following day to collect a sample from each well with a bailer. The results for both low -flow sampling and the triennial samples collected by bailer appeared to correlate in both wells sampled and it was determined the sampling method did not influence concentrations of COPCs. 2.3 Data Gap Assessment The historical data review and the baseline groundwater sampling data supported the completion of a data gap assessment to identify where additional sampling or analyses may be required to refine the Site conceptual model. The data gap assessment concluded that the Site -related COPCs above Permit groundwater standards at WWMW-1 and WWMW-2 are most likely derived from upgradient EHS Support LLC 4 Comprehensive Site Assessment —Bakelite Acme Assessment Activities groundwater; therefore, one new monitoring well south-southeast of the former lined pond was recommended to investigate an upgradient source of COPCs. 2.4 Groundwater Monitoring Well Installation Based on the data gap assessment identifying that the Site did not have an appropriately located monitoring well upgradient of the former lined pond area, a recommendation of the data gap assessment was to install a monitoring well (WWMW-3) southeast of the former lined pond area (Figure 2 and Figure 3). Specifically, the well was proposed to be installed upgradient of the former lined pond area in the southeast corner just outside of the former berm. Groundwater monitoring well WWMW-3 was subsequently installed in July 2022 to help define the horizontal extent of COPCs in Site groundwater and facilitate the generation of localized potentiometric surface in this area. The boring log including well construction details and the NCDEQ division of water resources well construction record are provided as Appendix A. The groundwater monitoring well was developed at least 24 hours after installation and groundwater samples were collected as part of the triennial sampling conducted in accordance with the Permit. The groundwater samples were analyzed for the permitted constituents along with natural attenuation parameters (sulfide, dissolved iron, and dissolved manganese as recommended in the data gap assessment). 2.5 Geochemical Evaluation The geochemical evaluation provided in the data gap assessment was updated for the CSA following the installation of WWMW-3 and an additional year of monitoring to update the findings and conclusions. Ir addition, the installation of WWMW-3 facilitated the development of groundwater contour maps (Figure 4 through Figure 7) to determine the localized flow direction of shallow groundwater at the Site. The geochemical evaluation is provided as Section 4. 2.6 Compliance Boundary Demonstration The compliance boundary demonstration leverages predictive calculations and modeling using BIOSCREEN and BIOCHLOR, Domenico based models. These models were produced to show groundwater contaminants will not exceed the CLRS Permit standards Mat the compliance boundary through natural site conditions, facility design, and operational controls as identified in 15A NCAC 02L .0106(d)(1). The input parameters, assumptions, and summary of this compliance boundary demonstration are provided in Section 5. EHS Support LLC Comprehensive Site Assessment —Bakelite Acme k14h..4--01-R Hydrogeological Framework 3 Hydrogeological Framework This section provides a summary of groundwater monitoring, Site COPCs, and hydrogeology of the Site. 3.1 Groundwater Monitoring Three wells WWMW-1, WWMW-2, and WWMW-3 are monitored triennially by Wood Environment & Infrastructure Solutions, Inc. (now WSP USA Environment & Infrastructure Inc.) of Wilmington, NC. Groundwater sampling is typically completed over two days. The depth to groundwater and purging of three well volumes with a bailer and collection of water quality parameters (temperature, pH, and specific conductivity) are completed on the first day of each sampling event. The following day, a set of water quality parameters is collected from each well at the time of sampling for the permitted constituents: • TOC • Formaldehyde Whole Water • Ammonia as N • Total Nitrate (as N) • pH • Total Phosphorus • TDS • Total Sulfate • VOCS In addition to the permitted constituents, the last three sampling events (July 2022 through March 2023) included the following constituents for the geochemical evaluation: • Dissolved iron • Dissolved manganese • Sulfide Field parameters including depth to water prior to purging, and water quality parameters collected at the time of sampling are provided on Table 1. The field sampling sheets are provided as Appendix B. 3.1.1 COPCs Based on the evaluation of groundwater monitoring results to Permit standards, the Site COPCs with their respective Permit standard are: • Ammonia — 1.5 milligrams per liter (mg/L) • Formaldehyde — 0.6 mg/L • Nitrate (as N) — 10 mg/L • Sulfate — 250 mg/L • TDS — 500 mg/L at 180 degrees Celsius (C) These COPCs were evaluated for this CSA as the Site groundwater contaminants in Section 4 and Section 5. Periodic detections of VOCs were observed (Table 2) in all three wells from April 2011 to March 2023 and reported in the triennial submittals of the Compliance Monitoring Form (GW-59). However, these were not evaluated for this CSA because the detections were sporadic and may be from an upgradient EHS Support LLC 6 Comprehensive Site Assessment — Bakelite Acme Hydrogeological Framework k7 groundwater source or potential lab contamination. Groundwater sample results are summarized in Table 2 and laboratory reports are provided in Appendix C. 3.2 Groundwater Flow The potentiometric surface map and groundwater elevations collected in 2016 and presented in the 2018 RI (Shield Engineering, Inc., 2018) indicated that groundwater beneath the former manufacturing area flows from the southeast to the northwest toward WWMW-1 and WWMW-2 (Figure 3-1). The 10- foot elevation contour has a notable northward bend around WWMW-1 immediately north of the former lined pond. The cause of the bend in the potentiometric surface was identified as a data gap as part of the data gap assessment, as it was uncertain if this condition was due to preferential infiltration from the former lined pond causing groundwater mounding in the vicinity of WWMW-2, or due to another cause. In July 2022, a new well (WWMW-3) was installed southeast of WWMW-2 to better understand constraints on groundwater flow and to obtain a sample upgradient of the former lined pond to identify if the feature or its removal in 2019 affected groundwater quality. Groundwater elevation data from the new WWMW-3 monitoring well indicate groundwater where the former lined pond was located flows consistently from east to west toward WWMW-2 (Figure 4 through Figure 7). Consequently, WWMW-2 provides a point directly downgradient of the former lined pond and can be used to identify water quality impacts attributed to the former lined pond or its removal. a Figure 3-1: Groundwater Elevations Measured in 2016 for the 2018 RI (Shield Engineering, Inc., 2018). EHS Support LLC 7 Comprehensive Site Assessment —Bakelite Acme ��� Hydrogeological Framework To better understand upgradient influences on groundwater quality, WWMW-1 and WWMW-3 are compared to concentration data for upgradient groundwater wells provided in the 2018 RI report and are further discussed in Section 4. Available water level data indicate groundwater elevations in WWMW-1 and WWMW-2 initially declined following removal of lined pond, supporting the idea that the former pond was a source of recharge. Water levels in WWMW-1, WWMW-2, and WWMW-3 show a recent increasing elevation trend, suggesting the groundwater system is re -equilibrating as groundwater from upgradient moves through the system (Figure 3-2). This supports the idea that infiltration to groundwater through the former lined pond is no longer occurring following closure of the pond and re -grading to redirect surface runoff away from the Site. Groundwater elevations from the RI to March 2023 are included in Appendix D. V 16 1/1/2016 6/14/2017 11/26/2018 5/9/2020 10/21/2021 Date Figure 3-2: Groundwater elevations for WWMW-1 through WWMW-3 (note, the dashed line represents the time between 2016 RI groundwater measurement and July 2019 measurement) EHS Support LLC Comprehensive Site Assessment — Bakelite Acme Geochemical Evaluation 4 Geochemical Evaluation k7 This section provides the details of the geochemical evaluation following the data gap assessment and one year of groundwater monitoring following the installation of WWMW-3. The geochemical assessment provides a primary line of evidence for the source of COPCs at WWMW-1 and WWMW-2. 4.1 Groundwater Geochemistry In addition to the standard analytes, samples were analyzed for sulfide, and field filtered (0.45 micron) dissolved iron and dissolved manganese to assess redox conditions as part of the geochemical evaluation. The results were evaluated in the context of the redox ladder, which refers to the order of preferential electron acceptor utilization in waters, which follows the sequence — Oz > NO3 > Mn(IV) > Fe(III) > S042- in progressively more reducing conditions (McMahon and Chapelle, 2008). Given the sequential nature of electron acceptor utilization, increased concentrations of the end products (ammonium [NH4'], dissolved manganese [Mn(II)], ferrous iron [Fe(II)], sulfide), and depleted electron acceptors (02, NO3, S042-) through water quality sampling can be used to identify redox conditions. The redox assessment results are summarized on Figure 8: • Samples from upgradient well WWMW-1 are highly reduced and sulfate/sulfide controls redox. • Samples from downgradient well WWMW-2 are oxic; sulfide is not detected; iron is very low; ammonia is low; and nitrate is elevated. The presence of manganese (a slightly more reducing indicator) suggests this water was once more reduced and is transforming to more oxidizing conditions or is a disequilibrium mixture between oxidized and reduced waters. • Groundwater in WWMW-3 is reduced, but low to non -detect sulfide suggests fewer reducing conditions than at WWMW-1. • In summary, natural attenuation of COPCs is occurring due to a combination of geochemical reactions and mixing with infiltrated precipitation. Figure 8 indicates a correlation between sulfate and sulfide in WWMW-1: elevated sulfate corresponds to lower sulfide and vice versa. Given that pH values are circum-neutral at WWMW-1 (Table 2), sulfide oxidation at this location is not likely as this process generates substantial acidity. This observation suggests that sulfate is transforming to sulfide at this location. Sulfide precipitation in groundwater at WWMW-1 is consistent with the field sampling logs, which indicate that a black color is present in samples (commonly a result of microcrystalline iron sulfide minerals precipitating) and an odor that is noted on the sampling logs suggesting hydrogen sulfide is present (Appendix B). Constituent cross plots indicate WWMW-1 is distinct in composition from WWMW-2 and WWMW-3, and the composition of samples from WWMW-1 can be explained by mixture of waters from upgradient wells MW-4 or MW-28 (Figure 9). WWMW-3 and downgradient well WWMW-2, and WWMW-2 appear to mixtures from background groundwater upgradient of the facility (represented by the 2016 sample reported in the RI from KMW-2) and WWMW-1. The pH data in combination with the redox conditions at WWMW-1 through WWMW-3 support this mixing model. Notably, the pH in downgradient well WWMW-2 is distinctly acidic compared to upgradient wells WWMW-1 and WWMW-3. A geochemical model using a simplified WWMW-1 composition illustrates a potential cause of the pH change in the downgradient direction (Figure 10). Complete oxidation of the sulfide measured in the WWMW-1 sample can conceivably result in a pH shift EHS Support LLC Comprehensive Site Assessment — Bakelite Acme Geochemical Evaluation �7 to acidic conditions of over 3.5 pH units. Analytical results at WWMW-2 compared to the upgradient wells further support this oxidation model. Specifically, sulfide is absent at WWMW-2, ammonia is depleted, and nitrate is elevated (indicating ammonia oxidation). The cause of the oxidation is potentially infiltration of oxidized precipitation into the area where the former lined pond was removed. 4.2 Disturbance to Soil During Lined Pond Closure During closure activities, four composite soil samples were collected from four quadrants of the base of the lined pond and four composite samples were collected from the four berms. Soil samples were collected from the 0 to 6-inch interval and were biased toward areas of potential impact, as determined by visual inspection and field screening using an organic vapor monitor and a formaldehyde monitor. The results of the composite soil sampling showed no exceedances of protection of groundwater standards for any of the COPCs (EHS Support, 2020). Detections of total Kjeldahl nitrogen, ammonia nitrogen, nitrate, and nitrogen were noted but only one detection of nitrite at a low concentration (J flagged by the laboratory for a lower concentration than the reporting limit). These results were consistent with no increases in these constituents in groundwater following soil removal activities. Furthermore, the absence of composite soil exceedances indicates an upgradient source for the nitrogen constituents that persistently exceed permit standards in WWMW-1 and WWMW-2. Formaldehyde and molybdenum were the only COPCs present in the berm and soil composite samples that exceeded their respective protection of groundwater standards (EHS Support, 2020). As there are no soil standards for the protection of groundwater for sulfate or TDS, and TDS cannot be directly measured in soil, soil composite sampling cannot be used to determine if berm soils used to fill the lined pond or in the soils that were left in -place were a source for these constituents to groundwater. In summary, composite sampling indicates that soil at the former lined pond is not the source of nitrogen compounds to groundwater at the Site. 4.3 Groundwater Concentration Trends The cause of increases in groundwater sulfate, formaldehyde, and TDS in 2020 following removal of the former lined pond were identified as a data gap. Hypotheses for the increasing trends include: • Changes in precipitation infiltration at the former lined pond led to decreased dilution. Changes in upgradient water quality. Soil disturbed during the lined pond closure construction temporarily led to elevated groundwater concentrations. Geochemical changes in samples during transit to the laboratory. Time series concentration data through March 2023, coupled with the revised understanding of groundwater flow directions described in Section 3.2, provide a basis for understanding the cause of the concentration increases (Figure 11 through Figure 13). The time series charts indicate that the concentration increases have generally decreased for most monitored parameters and have stabilized and returned to pre -closure conditions. A summary of the concentration trends is provided in Table 4-1 for the period of operation, after the lined pond was cleaned and after final closure activities.

Time series data for WWMW-1 and WWMW-2 indicate that concentrations remained stable throughout closure activities (Figure 11 and Figure 12). Ammonia concentrations are highest in well WWMW-1 (located upgradient of the former lined pond) and lowest in well WWMW-2 (located downgradient of the former lined pond). Nitrate is below the Permit standard in WWMW-1 and WWMW-3 but the groundwater concentrations at downgradient well WWMW-2 are above the standard. EHS Support LLC 11 Comprehensive Site Assessment — Bakelite Acme Geochemical Evaluation k7 These observations are interpreted to indicate that ammonia in wells WWMW-1 through WWMW-3 are from an upgradient source. The lower concentrations of ammonia at downgradient well WWMW-2 suggest that dilution from infiltration of precipitation where the former lined pond was located contributes to lower ammonia concentrations at WWMW-2. In addition, oxidation of ammonia to nitrate is supported by elevated nitrate above the Permit standard at downgradient well WWMW-2. 4.3.2 Formaldehyde Concentrations of formaldehyde in WWMW-1 had increased above the Permit standard briefly following removal of the former lined pond and have since returned to values below the Permit standard and returned to pre -removal levels. A brief increase in formaldehyde was observed in WWMW-2 following removal of the former lined pond, but concentrations have remained below the Permit standard and subsequently returned to pre -removal levels. Formaldehyde was below the Permit standard for all samples collected from WWMW-3. Formaldehyde concentrations briefly spiked following soil disturbance during removal of the lined pond but are now below the Permit standard in all three wells. 4.3.3 TDS Concentrations of TDS in WWMW-1 had increased above the Permit standard briefly following removal of the former lined pond and have since declined to pre -removal levels but still above the Permit standard. A brief increase in TDS was observed in WWMW-2 following removal of the former lined pond, but concentrations have remained near (above and below) the Permit standard. TDS was below the Permit standard for all samples collected from WWMW-3. 4.3.4 SulfotF Concentrations of sulfate in downgradient well WWMW-2 had increased above the Permit standard following removal of the former lined pond, and quickly decreased to below the standard in WWMW-2 by 2022. Between July 2022 and March 2023, sulfate was below the Permit standard in WWMW-3. Sulfate hovered above and below the Permit standard in WWMW-1 prior to pond removal, and increased following removal of the lined pond and has since persisted above the Permit standard although fluctuates seasonally. Elevated sulfate in downgradient well WWMW-2 in 2020 and 2021 was a temporary condition that occurred due to disturbance caused during removal of the former lined pond. Concentrations returned to below the Permit standard indicating that sulfate attenuates between the upgradient and downgradient points likely due to dilution by precipitation infiltration. The source of the sulfate is likely sulfide from a location upgradient of WWMW-1 and WWMW-3 that is oxidized to sulfate by infiltration of oxic precipitation. An increase in sulfate at WWMW-1 followed removal of the former lined pond. As indicated in Figure 4- 1, times of elevated sulfate in WWMW-1 correspond to periods of elevated precipitation (90 day rolling average) following removal of the former lined pond in 2019. It is not clear if the precipitation infiltration is mobilizing sulfate from soil disturbed during removal of the former lined pond, or if oxidation of sulfide in groundwater from an upgradient source is occurring as a result of precipitation infiltration.

The compliance boundary used for these models was the closest portion of Mill Creek in the direction of groundwater flow which may potentially discharge to surface water (Figure 7). 5.1 Approach BIOSCREEN (USEPA, 1997) and BIOCHLOR (USEPA, 2002) are screening models that simulate remediation through natural attenuation of dissolved components and were used to model the extent of the plume. The software was developed by Groundwater Services, Inc and the United States Air Force and uses the Domenico analytical solute transport model to simulate one -dimension advection, three - dimension dispersion, linear adsorption, and biotransformation. In addition, BIOCHLOR, can simulate the sequential degradation of one compound into another. The models were run for compounds exceeding their corresponding standard in the March 2023 sampling event: sulfate, ammonia nitrogen, nitrate, and TDS. As stated in Section 4.3, oxidation of ammonia to nitrate is supported by elevated nitrate above the Permit standard at downgradient well WWMW-2. For this model, nitrate was assumed to be the only degradation product of ammonia oxidation. Although BIOCHLOR is primarily programmed to model the reductive dechlorination of chlorinated ethenes and ethanes, it can also be used to model any compound that degrades via sequential first order decay kinetics by entering the yield constants for the specified reaction. In the model, ammonia was modeled as tetrachloroethene (PCE) and nitrate as the first daughter product, trichloroethene (TCE). The previously calculated half-life of 0.06 years for ammonia was used for ammonia degradation and the model was then calibrated to field data by adjusting the biodegradation half-life of nitrate until the model matched the concentrations measured at WWMW-2. The model -derived half-life for nitrate was found to be 0.02 years (7 days). The starting input parameters are organized into different screen boxes in BIOSCREEN and are summarized as follows: Hydrogeology. Seepage velocity, Vs, was entered directly into the model as this parameter was provided in the RI Report (Shield Engineering, Inc., 2018). Seepage velocities between 11 and 210 feet per year were reported and the highest velocity of 210 feet per year was selected for the model. Hydraulic conductivity, K, and hydraulic gradient, i, are not required if seepage velocity is provided as an input. However, porosity, n, is required for adsorption and mass calculations. For this parameter, the default value of 0.25 was accepted. Dispersion. As dispersivity is difficult to measure in the field, dispersivity was estimated in the calibration step described below. Longitudinal dispersivity, alpha x; transverse dispersivity, alpha y; and vertical dispersivity, alpha z were all calculated by the models using an estimated plume length. Adsorption. The models use a retardation factor, R, to calculate how sorption of contaminants to organic material in the solid aquifer matrix decreases advection of the contaminants through the plume. However, all dissolved contaminants considered in the model were ionic components. Thus, adsorption was assumed to be negligible, and R was set to 1 for all modeled contaminants. If R is entered, no other sorption parameters are needed in the models. EHS Support LLC 14 Comprehensive Site Assessment —Bakelite Acme Compliance Boundary Demonstration • Biodegradation. BIOSCREEN calculates plume length using three distinct methods: no degradation, first -order decay kinetics and instantaneous reaction kinetics. BIOCHLOR uses only the first two approaches. Degradation of TDS was assumed to be negligible and thus transport of this COPC was modeled with no degradation. The biodegrading rates for the other compounds were estimated in the calibration step, described in Section 5.2 below. The yield (required for BIOCHLOR only) is the the ratio of the daughter product molecular weight to the parent compound molecular weight which was calculated to be 3.6 for the oxidation of ammonia into nitrate. • Modeled Area Length and Width. The model area length was adjusted to include the entire plume. As only the centerline output is used for this model, the plume width was not required. • Simulation Time. The time of the simulation was adjusted as needed for each specific model. • Source Data. The default value of 10 feet for the source thickness in the saturated zone was used. Site data from the second quarterly sampling event was used for both calibrating plume properties and predicting plume extents. The source width was calibrated in the following step. Due to uncertainties in the source of the contaminants, the soluble mass of the source was assumed to be infinite as a conservative approach. • Field Data for Comparison. WWMW-1 and WWMW-2 were used to define the centerline of the plume to leverage field data in the model. Concentrations reported at these monitoring points during the March 2023 sampling event were used. To obtain distances for the compliance point (Mill Creek), a transect was determined parallel to groundwater flow using the groundwater contours (Figure 7) near each well. The distance between the contour lines was taken as the distance between WWMW-1 and WWMW-2 (90 feet). The distance from WWMW-2 to Mill Creek was 65 feet (in the direction of groundwater flow). • Output. Only the Centerline output was used for this model. 5.2 CaiiDrazion The BIOSCREEN and BIOCHLOR calibration input and output for each contaminant are provided in Appendix E and an example is provided on Figure 14. The TDS data for WWMW-1 and WWMW-2 was used to calibrate the model for plume length and source zone width, assuming negligible degradation of TDS along the length of the plume ("No Degradation" kinetics). It is important to note that for the model, WWMW-1 was modeled as the "source" as it was the most upgradient well with the highest concentration of each contaminant. However, this does not imply that WWMW-1 is the ultimate source of contaminants at the Site. Total plume length and source zone width were determined through an iterative process. The time was set to 1 year for the calibration step as the seepage velocity indicated that contaminants would travel the 90 feet between the two wells in this time. The other model parameters were used are exactly as described in Section 5.1. An initial approximation for plume length was estimated by plotting TDS at each well as a function of distance downgradient from WWMW-1 and extending the regression to determine the distance at which this linear approximation predicts the plume will end. BIOSCREEN was then run to determine the predicted length of the plume (here assumed to be the distance along the center line at which modeled concentration falls below 1% of initial concentration). This modeled value for the plume was then taken as the plume length and the model re -run. This step is consistent with the methodology described in the BIOSCREEN User's Manual (USEPA, 1996). The source zone width was then adjusted so that the concentration 90 feet downgradient matched those measured for WWMW-2. EHS Support LLC 15 Comprehensive Site Assessment — Bakelite Acme Compliance Boundary Demonstration �l From this process, the final plume length and source zone width were estimated to be 360 feet and 19 feet, respectively. BIOSCREEN's no degradation kinetics overpredicted the concentrations of sulfate and ammonia observed at WWMW-2, supporting the fact that degradation of these compounds occurs, in addition to dispersion of the plume as it moves downgradient. The biodegradation rates for degrading compounds (sulfate, ammonia) were then calibrated to field data by adjusting the biodegradation half-life until the model matched the concentrations measured at WWMW-2. The model -derived half-life for sulfate was found to be 0.55 years (200 days). The half-life for ammonia was found to be 0.06 years (22 days). As nitrate is assumed to be produced by the oxidation of ammonia, BIOCHLOR was used to model the production of nitrate as ammonia is degraded. 5.3 Plume Extent The BIOSCREEN and BIOCHLOR plume extent model input and output for each contaminant are provided in Appendix E and an example is provided on Figure 15. The model results are summarized in Table 5-1. The calibrated models were used to determine the concentration of each contaminant reaching the compliance point (receptor) 155 feet downgradient of WWMW-1 along the centerline of the plume. The simulation time was extended until concentration at the compliance point no longer increased to determine the maximum concentration expected at the compliance point. This occurred at simulation times longer than 4 years. Concentrations of TDS, sulfate, ammonia, and nitrate at the receptor were found to be 334 mg/L, 146 mg/L, 0.7 mg/L, and 1.0 mg/L respectively, all lower than the corresponding Permit standards. In summary, the modeled plume extent of these COPCs are below corresponding Permit Standards at the compliance boundary.

Oxidation reactions occur in groundwater as it flows beneath the area where the former lined pond was located by infiltration of precipitation. Sulfide is oxidized to sulfate which lowers the pH, and ammonia is oxidized to nitrate. The ammonia and sulfide that lead to the nitrate and pH exceedances at downgradient well WWMW-2 are present in upgradient wells WWMW-1 and WWMW-3, suggesting a source other than the former lined pond for these constituents. Acquisition of additional time series data indicates that concentration increases observed in 2019-2020 at WWMW-1 and WWMW-2 were a brief event that has returned to prior conditions for most constituents. The brief spike in concentrations is attributed to ground disturbance and modification of the hydrological system during construction activities related to closure of the former lined pond. BIOSCREEN and BIOCHLOR models incorporating the most recent concentrations of groundwater contaminants forecast that it will take approximately four years to reach peak concentrations. However, at these peak concentrations, the groundwater at the compliance point (closest portion of Mill Creek to WWMW-2) will not exceed the Permit standards and therefore do not require corrective action. 6.2 Conclusions Natural attenuation at the Site is occurring and is evident from the trend evaluations described in Section 4.3 and the BIOSCREEN and BIOCHLOR models described in Section 5. As modeled, the Site COPCs will be below Permit standards at the compliance boundary (Mill Creek). In November 2019, the Pond closure returned the Site to natural conditions (pre-CLRS) which allows infiltration of oxic stormwater. Ground disturbance during construction temporarily caused an increase in some reported COPCs. As noted in the Closure Report the source of the CURS constituents was removed and the residual COPCs in soil will continue to naturally attenuate (EHS Support, 2020). This Site is within the footprint of the Wright Chemical Corporation Superfund Site where several COPCs were detected at much higher concentrations in upgradient and sidegradient groundwater. This upgradient/sidegradient source of COPCs will continue to flux into the former CURS pond area until they are attenuated before reaching Mill Creek. As WWMW-2 is now the most downgradient well, future monitoring will continue to report COPCs from the upgradient sources. Since the source of most of the Site impacts is from upgradient / sidegradient groundwater contamination managed by the USEPA Region 4 superfund program, we recommend cessation of the triennial sampling for the CLRS Permit. Three years of data since the closure of the pond support natural attenuation is occurring as evidenced by the compliance boundary demonstration (Section 5).
