B.EXECUTIVE SUMMARY The Blalock Fina site, located at 3574 NC Highway 55 in Angier, North Carolina (site), is 0.69 acres (Figure 1). The property is vacant and consists of cleared land. The site formerly contained a gasoline station and convenience store, which began operation in 1957. The gas station was reportedly closed in 1989 and the underground storage tanks (USTs) were reportedly pumped dry and filled with a sand/cement/water slurry. A release from the former on-site UST system was discovered in February 2001, when laboratory analyses of soil samples collected following the removal of the USTs revealed the presence of petroleum contaminants. Subsequent environmental investigations at the site are summarized in the following sections. The North Carolina Department of Environmental Quality (NCDEQ) filed a Notice of Residual Petroleum (NRP) for soil and groundwater on December 9, 2016 prior to the sale of the property between the property owner at the time, Mr. Donald Blalock, and the purchaser, Mr. Scott Leonard. The NRP was filed with the Harnett County deed in Book 3462, Page 818-820. As requested by NCDEQ, Terracon mobilized to the site on March 30 and 31, 2023 to: n gauge depths to groundwater in monitoring wells; n measure the potential presence of free product in the wells; n collect field parameters to assess the effectiveness of the remedial activities performed in August 2021 that included the injection of RemRx™ Controlled Release Polymer (CRP) Persulfate and instantaneous release persulfate into multiple borings (Terracon, 2021); n collect samples from fifteen monitoring wells (MW-1, MW-3 through MW-12, RW-1, RW-2, VEW-1, and VEW-2) for analysis of volatile organic compounds (VOCs) and sulfate; and n Install two soil gas sample points (SG-01 and SG-02) at 5 feet below land surface (bls) and collect soil gas samples for analysis of VOCs. Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 3 Based on information obtained during the groundwater and soil gas monitoring activities, Terracon provides the following findings and conclusions: n Shallow groundwater depths in March 2023 ranged from 4.55 to 9.00 feet below top of casing (bTOC). The apparent direction of surficial groundwater flow was to the southwest. n Free product thicknesses were not detected in the monitoring wells. Free product has not been detected since May 2012 (in MW-5). n Benzene; ethylbenzene; isopropylbenzene; naphthalene; n-propylbenzene; toluene; 1,2,3-trichloropropane; 1,3,5-trimethylbenzene; 1,2,4-trimethylbenzene; and/or total xylenes were detected at concentrations above the 15A North Carolina Administrative Code (NCAC) 2L Groundwater Quality Standards (2L Standards) in wells MW-1, MW-3, MW-5, MW-6, MW-11, RW-1, RW-2, and VEW-1. n Petroleum constituents were not detected above the North Carolina Gross Contaminant Levels (GCLs) during this sampling event. Benzene has historically been detected above the GCL in MW-3 in January 2012 and in MW-5 in January 2018. n VOCs were detected above the laboratory reporting limits, but below the 2L Standards in MW-7, MW-8 and VEW-2. n VOCs were not detected above the laboratory reporting limits in MW-4, MW-9, MW-10, and MW-12. n Based on the analytical results of injectant indicators (i.e., sulfate, specific conductivity, and oxidation-reduction potential [ORP]), local spreading of RemRx™’s CRP Persulfate was indicated by higher average specific conductivity and ORP compared to the baseline sampling event and higher sulfate concentrations in monitoring wells located nearer and immediately downgradient of the injectant borings. A reduction in sulfate and conductivity values in the monitoring wells compared to previous sampling events may be due to dissipation of the instantaneous release persulfate. Additional monitoring events will aid in interpreting field measurement and analytical trends. n Groundwater samples from monitoring wells MW-3, MW-5, RW-1, and RW-2 in close proximity to the RemRx™ injection locations in August 2021 have exhibited limited concentration reductions. However, only three monitoring events (November 2022, February 2022, and September 2022) have occurred since the August 2021 injections; therefore, additional time may be needed for the RemRx™ injections to present larger concentration changes. Groundwater impacts extended off the site to the southwest. The groundwater contaminant plume appeared to be relatively stable and was generally delineated horizontally with the exception of the southeastern extent. The contaminant plume was not vertically delineated. n Seven potable water supply wells have historically been identified within 1,000 feet of the source area. These wells are located to the north, east, and south of the site and are topographically cross- to up-gradient in relation to the plume. Active potable wells have not been identified within 500 feet of the source area. Based on Terracon's receptor survey in Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 4 October 2019, municipal water was available to the site and properties located within 1,000 feet of the source area. n VOCs were detected above the laboratory reporting limits, but below NCDEQ Residential and Non-Residential Sub Slab and Exterior Soil Gas Screening Levels (SGSL) in SG-01 and SG-02. Terracon entered the maximum detected concentrations of the soil gas samples into the NCDEQ Risk Calculator (January 2023 version) to evaluate human health risk from vapor intrusion into the on-site residence. Based on the risk calculator results, the detected concentrations of VOCs do not present an unacceptable risk to the residence. Based on the results, additional evaluation of the PVI pathway is not warranted at this time. Further evaluation should be considered if the following occurs: o Extension of the residential building over a larger footprint on the site; o Connection of additional utilities to the on-site dwelling that may act as preferential pathways for soil vapor intrusion; o Petroleum concentrations in the on-site monitoring wells increase; or o Future releases occur on or adjacent to the site. C.SITE HISTORY AND CHARACTERIZATION The purpose of this report is to present the findings of assessment activities performed in March 2023 at the Blalock Fina site located at 3574 NC Highway 55 in Angier, Harnett County, North Carolina. This Quarterly Injection Performance Monitoring Report was prepared for the site in response to a request by Mr. Mark Petermann with the NCDEQ DWM, State Lead Program. The Quarterly Injection Performance Monitoring Report was prepared in general accordance with the 15A NCAC 2L .0115 regulations and the NCDEQ UST Section Assessment Guidelines and Corrective Action Guidelines for Petroleum and Hazardous Substance UST Releases / Petroleum Non-UST Releases,dated January 19, 2021, under the supervision of Mr. Donald R. Malone, a North Carolina registered professional engineer (North Carolina Professional Engineering License No. 20195). C.1 Site Setting The Blalock Fina site is comprised of 0.69 acres and consists of vacant, predominantly cleared land. The surrounding properties consist of residential properties to the west, south, and east with agricultural land to the north. The site and surrounding properties are depicted on Figures 2 and 3. C.2 Release Summary A petroleum release was discovered in February 2001, when laboratory analysis of soil samples collected following the removal of the former on-site USTs revealed the presence of petroleum contaminants (Armstrong Geological & Engineering Services, P.C., 2001). The site operated as a gasoline station and convenience store beginning in 1957. The site operated two 1,000- gallon gasoline USTs with a third 550-gallon gasoline UST added to the site in 1958. Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 5 Approximately 1,224 tons of contaminated soil was excavated during the UST removal activities in February 2001. A chronological summary of UST removal and subsequent assessment activities at the site is discussed in the following subsection of this report. C.3 Previous Investigations Investigation activities conducted between 2002 and the present included installation of twelve monitoring wells, two recovery wells, two vapor extraction wells, water supply well sampling, and a mobile multi-phase extraction (MMPE) event in 2004. An injection event was conducted in July 2011 that utilized chemical oxidation and oxygen-releasing compounds. The injectate consisted of a solution of 18% persulfate and 2% PermOx Plus into two separate areas at the site including the former source area on the north side of NC Highway 55 and a down-gradient area south of NC Highway 55. During the injection, vacuum extraction was applied to extraction wells and monitoring wells to remove contaminant mass, prevent groundwater mounding, and provide hydraulic control (Force Environmental Service Company, LLC, 2011). NCDEQ filed an NRP for soil and groundwater on December 9, 2016 prior to the sale of the property between the property owner at the time, Mr. Donald Blalock, and the purchaser, Mr. Scott Leonard. The NRP is filed with the deed in Book 3462, Page 818-820. From 2014 to the present, Terracon has conducted groundwater and soil investigations at the site to monitor the concentrations and extents of petroleum contamination. Due to the lack of plume delineation to the southeast of MW-3, Terracon installed monitoring well MW-12 in October 2019 (Terracon, 2019). In July and August 2021, Terracon completed a baseline groundwater sampling event of the monitoring well network prior to a persulfate injection at the site. Between August 23 and 25, 2021, Terracon completed the application of approximately 1,800 pounds of RemRx™ CRP Persulfate and 900 pounds of instantaneous release persulfate in 18 soil borings up to 18 feet below land surface to chemically enhance degradation of petroleum contaminants in groundwater (Figure 3) (Terracon, 2021). RemRx™ CRP Persulfate was utilized to establish in-situ chemical oxidation of the petroleum hydrocarbons by providing a sustained delivery of oxidizing persulfate ions (S2O82–) and sulfate radicals (SO4• –). RemRx™ developed the sustained-release process to reduce the potential for contaminant rebounding. Persulfate and the resulting sulfate radical anions degrade fuel-related constituents using reduction/oxidation chemistry and do not rely on the presence of naturally occurring or supplemental microbial bacteria. Between November 2021 and March 2023, Terracon completed four post-injection groundwater monitoring events after application of the RemRx™ CRP Persulfate. Local spreading of the CRP Persulfate was indicated by higher average specific conductivity and ORP compared to the baseline sampling event and higher sulfate and persulfate concentrations in some of the monitoring wells located nearer and immediately downgradient of the injectant borings. Overall reductions of conductivity, ORP, and sulfate concentrations in later post-injection monitoring events indicated an apparent dissipation of the instantaneous release persulfate (Terracon, Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 6 2022a; 2022b; 2022c, and 2022d). The results of the injection and other investigation activities were used to generate a conceptual site model of the current site conditions (Table 1). C.4 Water Supply Wells Terracon performed a receptor survey in October 2019 and identified thirteen water supply wells within 1,000 feet of the source area. At that time, seven of the thirteen wells appeared to be within 1,000 feet of the source area and serve as active, potable water sources. These wells were generally situated topographically cross- to up-gradient of the plume. The most proximate potable water supply well was WSW-5, located approximately 625 feet east of and cross- gradient to the source area. Downgradient water supply wells were either inactive or non-potable. Municipal water was available to the site and surrounding properties located within 1,000 feet of the source area. Results of the water-supply well inventory are in Table 2 and well locations are on Figure 3. D.ASSESSMENT INFORMATION Terracon mobilized to the site on March 30 and 31, 2023 to: n gauge depths to groundwater in monitoring wells; n measure the potential presence of free product in the wells; n collect field parameters to assess the effectiveness of the remedial activities performed in August 2021 that included the injection of RemRx™ CRP Persulfate and instantaneous release persulfate into multiple borings (Terracon, 2021); n collect samples from fifteen monitoring wells (MW-1, MW-3 through MW-12, RW-1, RW-2, VEW-1, and VEW-2) for analysis of VOCs and sulfate; and n Install two soil gas sample points 4.5 to 5 feet bls and collect soil gas samples for analysis of VOCs. D.1 Free Product Evaluation Free product was not detected in the monitoring wells during this assessment. Free product has not been detected since May 2012 (in MW-5). D.2 Groundwater Sampling Activities Prior to sample collection, Terracon gauged the depth to groundwater in the monitoring wells. Current and historical groundwater elevation measurements are in Table 3. Shallow groundwater depths in March 2023 ranged from 4.55 to 9.00 feet bTOC. The apparent direction of surficial groundwater flow direction was to the southwest based on the calculated groundwater elevations. Groundwater elevations from the March 2023 gauging event are in Figure 4. The manway for MW-1 was observed to be located below the existing land grade and Terracon recommends raising the manway for continued integrity of the well. Copies of field notes and a photographic log are in Appendix A. Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 7 Prior to sampling, the wells were purged with a peristaltic pump using low flow sampling techniques (i.e., <200 milliliters per minute) prior to sampling. Field parameters consisting of pH, temperature, ORP, dissolved oxygen, and specific conductivity were measured at each of the well locations. After stabilization of pH and specific conductivity, a groundwater sample was collected directly into laboratory-supplied containers at low-flow sampling rates. The groundwater samples were placed in laboratory-supplied glassware, labeled, and stored in an ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to Pace Analytical Services, LLC, in Huntersville, North Carolina for analysis of VOCs by United States Environmental Protection Agency (USEPA) Method 6200B, including methyl tert-butyl ether, EDB, and di-isopropyl ether, and sulfate by USEPA Method 9056A. D.3 Field Groundwater Measurements and Sulfate Analytical Results The groundwater field parameters measured in the monitoring wells from this event and comparisons to baseline average measurements (Table 4) are summarized below: n pH field measurements in the monitoring wells ranged from 4.53 to 6.39 standard units (s.u.) and were on average 1.21 s.u. lower than the baseline sampling event. This is not remarkable because of the strong buffering capacity of typical aquifer-matrix soils. n Specific conductivity measurements in the monitoring wells ranged from 34 to 800 microsiemens per centimeter (μS/cm). Specific conductivity is a surrogate for the quantity of ions present in water; and thus, provides an indicator for the presence of sulfate, persulfate, and perhaps other naturally occurring ions that might have been released from aquifer matrix due to the remedial injections. The average conductivity measurements in March 2023 were approximately 30 μS/cm higher than the baseline sampling event and the quarterly monitoring event in September 2022. MW-4, which is very near to remedial injections had significantly higher specific conductivity values as compared to the baseline event; however, most of the other wells had similar conductivity values as compared to the baseline event. n Dissolved oxygen measurements in the monitoring wells ranged from 0.07 to 9.06 milligrams per liter (mg/L) and were on average approximately 0.3 mg/L lower than the baseline sampling event. Oxygen concentrations vary from event to event, mainly due to infiltration and recharge from rain events, and these small concentration changes likely are not directly related to the remedial injections. n ORP measurements in the monitoring wells ranged from -150.7 to 283.2 millivolts (mV). ORP is a measure of the activity or strength of a water system to transfer electrons either by oxidizing processes (increasing and/or positive ORP values) or reducing processes (lower or negative ORP values). The ORP measurements in March 2023 were on average 145 mV higher than the baseline sampling event and approximately 62 mV lower than the quarterly monitoring event in September 2022. This indicates that the RemRx™ CRP Persulfate injected into the surficial aquifer initially Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 8 increased the oxidation potential of groundwater, especially in wells near to the injection areas; however, the oxidation potential appears to be decreasing over time as the mass of CRP decreases. Dissolved sulfate can be present naturally in groundwater. Terracon did not collect initial background sulfate concentrations prior to the remedial injections; however, the average sulfate concentration was 5 mg/L in the “background” monitoring wells upgradient or fairly distant from the injection borings (MW-7, MW-9, MW-10, and MW-12). Therefore, we consider 5 mg/L as a reasonable background concentration for sulfate at the site. The RemRx™ CRP Persulfate releases sulfate during the reaction and/or decay the S2O82– and SO4• – ions. Likewise, some of the microorganisms in groundwater can utilize sulfate as an alternative electron acceptor to drive anaerobic bio-oxidation of the petroleum hydrocarbons via the sulfate reduction pathway. The average sulfate concentrations ranged from 233 mg/L in November 2021 to 62 mg/L in March 2023 in “non-background wells” immediately adjacent to and downgradient of the RemRx™ CRP Persulfate injection borings (i.e., MW-1 through MW-6, MW-8, RW-1, RW-2, VEW-1, and VEW-2). Therefore, average sulfate concentrations in these monitoring wells decreased by approximately 170 mg/L from November 2021 to March 2023, likely due to decay of the instantaneous release persulfate and the CRP. The sulfate concentrations in downgradient monitor wells RW-2 and VEW-1 were less than the background sulfate concentration for the site; however, sulfate concentrations in downgradient monitor wells VEW-2, MW-6, MW-8, and MW-11 remained elevated above background. D.4 Groundwater Analytical Results Based on the laboratory analytical report, benzene; ethylbenzene; isopropylbenzene; naphthalene; n-propylbenzene; toluene; 1,2,3-trichloropropane; 1,3,5-trimethylbenzene; 1,2,4-trimethylbenzene; and/or total xylenes were detected at concentrations above the 2L Standards in wells MW-1, MW-3, MW-5, MW-6, MW-11, RW-1, RW-2, and VEW-1. Petroleum constituents were not detected above the GCLs during this sampling event. Benzene has historically been detected above the GCL in MW-3 in January 2012 and in MW-5 in January 2018. VOCs were detected above the laboratory reporting limits, but below the 2L Standards in MW-7, MW-8, and VEW-2. VOCs were not detected above the laboratory reporting limits in MW-4, MW-9, MW-10, and MW-12. Groundwater analytical results are in Figure 5 and Table 5. A copy of the laboratory analytical report is in Appendix B.Isoconcentration maps for the five leading petroleum contaminants (benzene; naphthalene; toluene; 1,2,4-trimethylbenzene; and total xylenes) are on Figures 6, 7,8, 9, and 10, respectively. These maps show the contaminant plumes generally originating from the south-central portion of the site in the source area and migrating to the west- southwest underneath NC Highway 55 and onto the adjacent southwestern property. Terracon evaluated the trends in petroleum constituents in monitoring wells immediately adjacent to and downgradient of the remediation area (MW-3, MW-4, MW-5, MW-6, MW-8, Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 9 VEW-1, and VEW-2). Apparent reductions in constituent concentrations are not yet apparent. Therefore, future monitoring events will be required to assess the success of the selected remedial strategy. The groundwater contaminant plume appears to be relatively stable and is generally delineated horizontally with the exception of the southeastern extent. The extent of groundwater impact is not vertically delineated. Active potable wells are not located within 500 feet of the source area. D.5 Soil Gas Sample Point Construction The soil vapor points were constructed in general accordance with the practices outlined in the NCDEQ DWM Vapor Intrusion Guidance (March 2018), the ITRC Vapor Intrusion Pathway: A Practical Guideline (January 2007), and the ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (October 2014). The temporary soil vapor points were constructed in a borehole advanced to 5 feet bls via a handheld Hilti hammer drill utilizing decontaminated 1.25-inch steel rods and a disposable steel drive point. The temporary soil vapor points were constructed as follows: n Installation of a 6-inch stainless steel soil gas implant from 4.5 to 5 feet bls; n Installation of 0.25-inch outside diameter Teflon® lined tubing to the ground surface; n Placement of sand in the borehole annulus to approximately one foot above the bottom of the borehole, followed by hydrated bentonite to the ground surface. After installation, the Teflon® lined tubing was capped and the soil vapor points were allowed to equilibrate for at least two hours before sampling. Prior to sampling, a 0.25-inch outside diameter Teflon® lined tube and Swagelok® fittings were used to connect the monitoring point assembly to a laboratory-supplied, batch-certified 1.0-liter Summa® canister. A helium tracer test was conducted prior to collecting the samples. The tracer test serves as a quality assurance/quality control (QA/QC) method to verify the integrity of the soil vapor point seal in addition to the connection of the sampling manifold and the soil vapor point. An MGD-2002 helium detector capable of measuring helium concentrations down to 25 parts per million (ppm) was used to verify the presence and concentration of helium in the sample point and/or within the sampling manifold. The protocol for using a tracer gas is to enclose the sampling point and the sampling manifold with a shroud. The helium tracer gas is released into the shroud until the atmosphere inside the shroud is approximately 10 to 20 percent helium. Approximately three purge volumes (one purge volume being equal to the volume within the borehole) were evacuated through Teflon®- lined tubing that passes through the shroud using a hand pump. Purge samples were screened for helium to assess for leaks in the well seal and/or sampling manifold after removal of each well volume. The annulus is considered to be sufficiently sealed when helium concentrations detected within the sampling points were less than ten percent of the helium concentration in Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 10 the shroud. The shroud was enriched with greater than 10 percent helium. Helium was not detected within the sample points at concentrations greater than the field instrument detection limit (25 ppm [i.e., 0.0025 percent]). Purged soil gas was also screened with a miniRAE 3000 photoionization detector to assess for VOCs. The shroud helium concentration and the helium concentration in the purged soil vapor was documented after each volume purged. After completion of the helium tracer test, the valve of the purge device was closed, and the sample canister valve was opened to collect soil vapor for laboratory analysis. The samples were collected in a laboratory supplied, batch-certified 1.0-liter Summa® canister connected to sample tubing using Swagelok® fittings at the soil vapor point. The sample canisters were filled using a dedicated flow controller set to a sample rate of less than or equal to 200 ml/min and the sample collection duration was 5 minutes. An in-line vacuum gauge was installed to the sample controller to verify initial vacuum levels within the canister and as an indicator that the target final pressure had been reached (i.e. sampling is complete). The sample canister valve was closed when the gauge measured -6 inches in Hg vacuum. After completion of the sampling activities, the soil vapor point was abandoned by removing the tubing. The location of the soil gas points (SG-01 and SG-02) is depicted in Figure 11. Photographs and field notes are in Appendix A. The soil vapor samples were shipped via FedEx to Pace Analytical National Center for Testing and Innovation in Mount Juliet, Tennessee under standard chain-of-custody procedures and analyzed for VOCs via USEPA Method TO-15. D.6 Soil Gas Analytical Results Soil gas analytical results were compared with the NCDEQ Residential and Non-Residential SGSLs. Multiple VOCs were detected above their laboratory reporting limits, but below their respective Residential and Non-Residential SGSLs. Terracon entered the maximum detected concentrations from the soil gas samples into the NCDEQ Risk Calculator (January 2023 version) to evaluate human health risk from vapor intrusion into the on-site residence. Based on the risk calculator results, the cumulative carcinogenic risk and non-carcinogenic hazard index were below NCDEQ risk thresholds (1E-04 and 1.0, respectively) for residential and non- residential soil gas to indoor air scenarios. Therefore, the detected concentrations of VOCs do not present an unacceptable risk to the residence. Soil gas analytical results are in Table 6. A copy of the laboratory analytical report is in Appendix B.A copy of the risk calculator results are in Appendix C. E.CONCLUSIONS AND RECOMMENDATIONS Terracon provides the following findings and conclusions based on the information obtained during this and prior groundwater monitoring events: Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 11 n Shallow groundwater depths in March 2023 ranged from 4.55 to 9.00 feet bTOC.

Benzene has historically been detected above the GCL in MW-3 in January 2012 and in MW-5 in January 2018. n VOCs were detected above the laboratory reporting limits, but below the 2L Standards in MW-7, MW-8 and VEW-2. n VOCs were not detected above the laboratory reporting limits in MW-4, MW-9, MW-10, and MW-12. n Based on the analytical results of injectant indicators (i.e., sulfate, specific conductivity, and ORP), local spreading of RemRx™’s CRP Persulfate was indicated by higher average specific conductivity and ORP compared to the baseline sampling event and higher sulfate concentrations in monitoring wells located nearer and immediately downgradient of the injectant borings. A reduction in sulfate and conductivity values in the monitoring wells compared to previous sampling events may be due to dissipation of the instantaneous release persulfate. Additional monitoring events will aid in interpreting field measurement and analytical trends. n Groundwater samples from monitoring wells MW-3, MW-5, RW-1, and RW-2 in close proximity to the RemRx™ injection locations in August 2021 have exhibited limited concentration reductions. However, only three monitoring events (November 2022, February 2022, and September 2022) have occurred since the August 2021 injections; therefore, and additional time may be needed for the RemRx™ injections to present larger concentration changes. Groundwater impacts extended off the site to the southwest. The groundwater contaminant plume appeared to be relatively stable and was generally delineated horizontally with the exception of the southeastern extent. The contaminant plume was not vertically delineated. n Seven potable water supply wells have historically been identified within 1,000 feet of the source area. These wells are located to the north, east, and south of the site and are topographically cross- to up-gradient in relation to the plume. Active potable wells have not been identified within 500 feet of the source area. Based on Terracon's receptor survey in October 2019, municipal water was available to the site and properties located within 1,000 feet of the source area. n VOCs were detected above the laboratory reporting limits, but below NCDEQ Residential and Non-Residential SGSLs in SG-01 and SG-02. Terracon entered the maximum detected Blalock Fina Angier, North Carolina Terracon Project No. 70149672B Incident No. 24238 May 23, 2023 Explore with us 12 concentrations of the soil gas samples into the NCDEQ Risk Calculator (January 2023 version) to evaluate human health risk from vapor intrusion into the on-site residence. Based on the risk calculator results, the detected concentrations of VOCs do not present an unacceptable risk to the residence. Based on the results, additional evaluation of the PVI pathway is not warranted at this time. Further evaluation should be considered if the following occurs: o Extension of the residential building that creates a larger footprint on the site; o Connection of additional utilities to the on-site dwelling that may act as preferential pathways for soil vapor intrusion; o Petroleum concentrations in the on-site monitoring wells increase; or o Future releases occur on or adjacent to the site. Based on the data presented in this Quarterly Injection Performance Monitoring Report, Terracon recommends the following activities be completed at the site. n Conduct quarterly measurements of groundwater field parameters (e.g., pH, conductivity, and ORP) to evaluate the distribution and release of the CRP Persulfate. In addition, semi-annual groundwater monitoring events should be conducted to evaluate the effectiveness of the CRP Persulfate in remediating petroleum contaminants in groundwater at the site. Groundwater samples from the semi-annual monitoring events should be analyzed for VOCs and sulfate to evaluate the distribution and release of the CRP Persulfate. The next quarterly event should be conducted in June 2022 and the next semi-annual event should be conducted in September 2023. The future events would be performed by other NCDEQ contractors. n Raise the manway for MW-1 to the existing land grade to ensure continued integrity of the well. n After collection and assessment of this additional data, NCDEQ should consider whether to: o perform additional monitoring without further active remediation, o perform an additional RemRx™ injection event, and/or o perform an air sparging pilot test to evaluate the potential use of physical removal methods (i.e., the low pH conditions at the site could cause in-situ bioremediation approaches to have limited successes).

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Terracon - Raleigh, NC 70149672B L1600695 04/14/23 15:45 16 of 18 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Terracon - Raleigh, NC 70149672B L1600695 04/14/23 16:00 16 of 18 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Terracon - Raleigh, NC 70149672B L1600695 04/14/23 15:45 17 of 18 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Terracon - Raleigh, NC 70149672B L1600695 04/14/23 16:00 17 of 18 APPENDIX C SOIL GAS RISK CALCULATOR RESULTS Version Date: Basis: Site Name: Site Address: DEQ Section: Site ID: Exposure Unit ID: Submittal Date: Reviewed By: 5/16/2023 Prepared By:Ethan Dinwiddie, PG Justin Fabriziani, RSM On-site Residence North Carolina Department of Environmental Quality Risk Calculator Blalock Fina 3574 NC Hwy 55, Angier, NC NCDEQ UST Section UST Incident #24238 January 2023 November 2022 EPA RSL Table North Carolina DEQ Risk Calculator Complete Exposure Pathways Version Date: January 2023 Basis: November 2022 EPA RSL Table Site ID: UST Incident #24238 Exposure Unit ID: On-site Residence Note: Risk output will only be calculated for complete exposure pathways.
