Summary of Activities Associated with Current TA WR completed a site‐wide groundwater monitoring event in association with TA‐01. Activities associated with this TA were completed on July 27, 2023. Sampling of site monitoring wells was completed as a follow‐up to the completion of Initial Abatement Actions in March/April 2019 and supplemental abatement actions completed during May 2021. 2. Soil, Groundwater and LNAPL Assessment Information Soils No soil sampling was performed at the facility in association with this TA. Between March and April 2019, WR oversaw and directed the excavation of a total of 246.87 tons of petroleum contaminated soils from the site, which were transported to an NCDEQ permitted soil remediation facility for treatment/disposal. Following excavation of affected soils, WR obtained requisite “confirmatory samples” from the excavation sidewalls for laboratory analysis. Prior to backfilling and site restoration, RemRX™ CRP Persulfate was emplaced in the base of the excavated area in contact with groundwater in an effort to induce oxidative degradation of petroleum contaminants in the aquifer. Data for samples obtained from locations along the sidewalls of the excavated area just above the groundwater interface showed low levels of benzene in three of eight samples at levels in excess of the Soil to Water Maximum Soil Contaminant Concentration (MSCC) for the compound. Naphthalene, 1,2,4‐trimethylbenzene and total xylenes were also reported at low levels in one of these samples at concentrations above their Soil to Water MSCCs. These data indicate that minor soil contamination remains along the western and southwestern sides of the excavated area, however, the bulk of contaminated soils have been removed. Groundwater Laboratory results for groundwater samples obtained from site monitoring wells during July 2023 showed impact by petroleum compounds at concentrations exceeding their respective Maximum Allowable Concentrations established by NCAC Title 15A, Subchapter 2L, Section .0202 (Water Quality Standards for Class GA Groundwater) or the “2L Standards” in samples from monitoring wells MW‐2R, MW‐5, MW‐8, MW‐10, MW‐11, MW‐12 and MW‐13. No compounds were reported at levels exceeding their Gross Contaminant Levels (GCLs). Results of “natural attenuation” and “engineering” analyses performed on groundwater samples from select wells are discussed in Section D.4 of this report. Based on the July 2023 groundwater sampling event performed at the site, the extent of groundwater contamination appears adequately defined. Contaminant concentrations appear to decrease appreciably with distance from the source area on the site. While fluctuations in contaminant levels (based on total BTEX concentrations) have occurred over the January – July 2023 period, current data shows that marked decreases in contaminants have occurred since remedial actions were completed. Total BTEX concentrations reported in source area well MW‐ 2R in January 2023 showed a 56% decrease over data from January 2023 and a 10% increase in MW‐10 over the same period. Overall, general decreases in contaminants were observed in WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 4 remaining wells in which contaminants were identified, with the exception of MW‐5. Data for wells MW‐12 and MW‐13 showed decreases (68% and 80%, respectively) in total BTEX concentrations over the January 2023 data. Based on groundwater level measurements obtained during the July 2023 sampling event, the direction of groundwater flow is easterly towards Pender’s Mill Run, a tributary of the Tar River. Pender’s Mill‐Run approaches to within 800 feet to the east of the source area. Groundwater elevations as measured in July 2023 are consistent with previous interpretations of flow direction. LNAPL/Free Product No LNAPL/Free Product has been identified in association with the release at the site, to date. 3. Receptor Information As a part of the receptor survey update performed in April 2015, WR identified the presence of 10 water supply wells within 1,000 feet of the source area on the site. Of these wells, one (WSW‐ 4) was utilized as an active, potable water supply; three (WSW‐3, WSW‐5 and WSW‐8) were utilized as non‐potable water supplies, and six (WSW‐1, WSW‐2, WSW‐5A, WSW‐7, WSW‐8A and WSW‐9) were found to be inactive. Potable water is available to the site and surrounding area from the Edgecombe County water supply system and is in use at the site and surrounding properties, with the exception of the location of WSW‐4. The owner/user of WSW‐4 has repeatedly denied past WR requests to obtain samples from the supply well. Laboratory results for a sample obtained from supply well WSW‐3 in July 2023 showed naphthalene present at a level beneath the 2L Standards. This well is utilized solely as a non‐ potable source. 4. Remediation Activities In addition to the removal of the USTs in July 1994, initial abatement activities were completed in April 2019 (Section D) augmented by the placement of reactive materials in 20 borings installed on the site during May 2021 (Section E). 5. Recommendations Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  Continued monitoring of site groundwater conditions through semi‐annual monitoring.  Annual sampling of supply well WSW‐3.

SITE HISTORY AND CHARACTERIZATION WR has completed a groundwater monitoring well sampling event for the referenced site in association with TA‐01 at the facility. The following information summarizes the site history and characterization. 1. UST Information 1.1 Former USTs Two gasoline USTs of 1,000‐ and 550‐gallon capacities were permanently closed‐by removal in June/July 1994. These USTs had been utilized for storage of fuels for retail sale to the public. The attached Table B‐1 summarizes known information regarding the onsite UST system. The location of the site imposed on the USGS Topographic Map for the vicinity is included as Figure 1, while site improvements, including former USTs and monitoring well locations are depicted on Figure 2. 2. Description of Release/General Assessment History The following summary of the assessment history is based on WR’s review of historical files for the subject incident:  According to historical information provided in the file, Batts Grocery formerly operated retail fueling services.  Two USTs were reportedly removed in July 1994.  East Coast Environmental collected a soil sample from the former UST tank bed during removal activities. Laboratory analytical results for soil samples collected from the former UST tank bed indicated the presence of total petroleum hydrocarbons (TPH)‐gasoline range organics (GRO) at concentrations that exceeded the State Action Level of 10 mg/kg.  In September 2009, a Phase I Limited Site Assessment (LSA) was completed with a groundwater monitoring well (MW‐1) installed proximal to the former UST tank bed. Following installation, a groundwater sample was collected from the well for laboratory analysis. Analytical results for the groundwater sample indicated the presence of petroleum constituents at concentrations above their respective 2L Standards.  A receptor survey performed during the Phase I LSA in September 2009 identified eight potable water supply wells within 1,000 feet of the source area.  Between June 2010 and June 2011, Terraine Environmental completed 3 groundwater sampling events at the site that consisted of sampling MW‐1. Laboratory results revealed C5‐ C8 aliphatic, C9‐C22 aromatics, and/or lead above 2L standards. Water supply wells sampled during these events did not reveal analytes of concern above 2L standards.  In October 2012 and February 2013, Crawford Environmental Services (CES) installed groundwater monitoring wells MW‐2 through MW‐6 and subsequently sampled the wells. Analytical results from the groundwater wells indicated the presence of VOCs above the 2L Standard in MW‐2 and MW‐5. In addition, lead was reported in MW‐2 above its 2L Standard.  WR obtained groundwater samples from site monitoring wells MW‐1 through MW‐6, inclusive, and supply well samples from WSW‐3, WSW‐5 and WSW‐8 on July 10, 2014. Data WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 6 for groundwater samples showed one or more target VOCs and total lead at levels exceeding their respective 2L Standards in MW‐2 and MW‐5. Analytical results for water supply well samples obtained from WSW‐3, WSW‐5 and WSW‐8 did not indicate the presence of petroleum‐related compounds at levels exceeding the method detection limit (MDL) for SM6200B.  WR obtained groundwater samples from monitoring wells MW‐1 through MW‐6 on May 4, 2015. Results indicated one or more compounds in samples obtained from MW‐1, MW‐2, and MW‐5. One or more compounds detected in MW‐2 and MW‐5 exceeded their respective 2L Standards. Detectable concentrations of lead were reported for the samples from MW‐1, MW‐2, MW‐4, and MW‐5. The concentration of lead in the sample from MW‐5 exceeded its 2L Standard.  WR performed assessment activities at the site during November 2015 including the installation of monitoring wells MW‐7, MW‐8 and MW‐9, gauging, purging and sampling of the newly and previously installed monitoring wells on the property, purged and sampled supply well WSW‐3 and placed Adventus® O‐SOX within monitoring wells MW‐1, MW‐2, and MW‐5. Laboratory results for groundwater samples obtained from site monitoring indicated the presence of one or more petroleum compounds in the samples collected from MW‐2, MW‐5, MW‐8, and MW‐9 at concentrations in excess of their respective 2L Standards. Lead concentrations reported in groundwater samples from MW‐2 and MW‐8 also exceeded 2L Standard. No compounds identified in any groundwater samples were reported at concentrations above their respective GCLs. The greatest concentrations of contaminants were noted in the vicinity of monitoring well MW‐2, situated in close proximity to the former pump island on the site. Contaminants appeared to extend hydraulically down‐gradient of the former pump island area to the east. Results for the sample obtained from water supply well WSW‐3 indicated the presence of one or more compounds, typically associated with chlorination, at levels above the method detection limits for SM6200B. Bromodichloromethane was reported in the sample obtained from the well at a concentration of 8.79 µg/L, which exceeds its 2L standard of 0.6 µg/L.  In December 2016, WR supervised the installation of temporary monitoring well TW‐1, obtained a Shelby tube sample for characterization of soil properties, obtained soil and groundwater samples for characterization of soil oxidant demand (SOD) and base buffering capacity (BBC), performed a site‐wide groundwater monitoring event and a limited supply well sampling event. In addition, WR completed the performance of aquifer slug tests on monitoring wells MW‐2, MW‐3 and MW‐8. Groundwater analytical results showed petroleum compounds at concentrations exceeding their respective 2L Standards in samples from monitoring wells MW‐2, MW‐5 and MW‐8. Iron, lead and manganese were reported at levels above their respective 2L Standards in each of the wells sampled (MW‐1 through MW‐9, inclusive). None of these elements were reported at levels exceeding their respective GCLs where established. Nitrate and sulfate were reported in several of the wells sampled at levels below their respective 2L Standards. Phosphorous (for which there is no current 2L Standard) was reported in well MW‐5 at a concentration of 366 ug/L. The arithmetic mean hydraulic conductivity determined based on the results of slug tests performed on MW‐2, MW‐3 and MW‐8 was found to be 5.2 ft/day or 0.0018 cm/sec, while the geometric mean for the same wells was found to be 3.8 ft/day or 0.0013 cm/sec.  January 2018 – WR completed a site‐wide groundwater monitoring event and collected supply well samples from select water supply wells. Laboratory results for groundwater samples WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 7 obtained from site monitoring wells during January 2018 showed impact by petroleum compounds at concentrations exceeding their respective 2L Standards in samples from monitoring wells MW‐2, MW‐5 and MW‐8. No compounds were reported at levels exceeding their respective GCLs defined by NCDEQ. Data for supply well samples obtained from select water supply wells showed several targeted compounds in the sample from WSW‐8, including bromodichloromethane, chlorodibromomethane and chloroform, three compounds often associated with “shock chlorination” of supply wells. The level of bromodichloromethane detected in the sample was in excess of the 2L Standard for the compound.  September 2018 – WR completed a bid package addressing the excavation and off‐site disposal of petroleum contaminated soils at the location. Based on bids submitted for this work by several bidders, Ready Contractors, Inc. (Ready) of Wilson, NC was awarded the work.  January 2019 – WR completed a “Baseline” groundwater monitoring event in preparation for the completion of remedial activities at the location. Laboratory results for groundwater samples obtained from site monitoring wells during January 2019 showed impact by petroleum compounds at concentrations exceeding their respective Maximum Allowable Concentrations established by NCAC Title 15A, Subchapter 2L, Section .0202 (Water Quality Standards for Class GA Groundwater) or the “2L Standards” in samples from monitoring wells MW‐2, MW‐ 5, MW‐7, MW‐10, MW‐11, MW‐12 and MW‐13. No compounds were reported at levels exceeding their respective Gross Contaminant Levels (GCLs) defined by NCDEQ. Based on the January 2019 groundwater sampling event performed at the site, the extent of groundwater contamination appeared to be adequately defined for the purposes of remediation. Contaminant concentrations decrease appreciably with distance from the source area on the site, however, fluctuations in contaminant levels (based on total BTEX concentrations) are occurring, possibly relating to seasonal changes in groundwater elevations and “washing” of contaminants from impacted soils.  March‐April 2019 ‐ WR oversaw and directed the excavation of a total of 246.87 tons of petroleum contaminated soils from the site, which were transported to an NCDEQ permitted soil remediation facility for treatment/disposal. Following excavation of affected soils, WR obtained requisite “confirmatory samples” from the excavation sidewalls for laboratory analysis. Prior to backfilling and site restoration, RemRX™ CRP Persulfate was emplaced in the base of the excavated area in contact with groundwater in an effort to induce oxidative degradation of petroleum contaminants in the aquifer. Data for samples obtained from locations along the sidewalls of the excavated area just above the groundwater interface showed low levels of benzene in three of eight samples at levels in excess of the Soil to Water Maximum Soil Contaminant Concentration (MSCC) for the compound. Naphthalene, 1,2,4‐ trimethylbenzene and total xylenes were also reported at low levels in one of these samples at concentrations above their Soil to Water MSCCs. These data indicate that minor soil contamination remains along the western and southwestern sides of the excavated area, however, the bulk of contaminated soils have been removed. (See Section D, below).  April 2019 – WR completed a limited groundwater sampling event at the facility. Analytical results for the groundwater samples obtained from site monitoring wells on April 15, 2019 showed one or more petroleum compounds in each of the wells sampled (with the exception of MW‐11) at concentrations exceeding their respective 2L Standards. Samples from each of the wells showed general decreases in total BTEX concentrations, with the exception of MW‐ 8, which showed a minor increase (no BTEX compounds were shown in the well in January 2019). No contaminants were reported at concentrations exceeding their respective GCLs. WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 8  June 2019 ‐ WR completed a limited groundwater sampling event at the facility. Analytical results for the groundwater samples obtained from site monitoring wells on June 4, 2019 showed one or more petroleum compounds in each of the wells sampled (with the exception of MW‐11) at concentrations exceeding their respective 2L Standards. Samples from each of the wells showed general decreases in total BTEX concentrations, with the exception of MW‐ 8, which showed a minor increase (no BTEX compounds were shown in the well in January 2019).  July 2019 ‐ WR completed a limited groundwater sampling event at the facility. Analytical results for the groundwater samples obtained from site monitoring wells on July 25, 2019 showed one or more petroleum compounds in each of the wells sampled (with the exception of MW‐3) at concentrations exceeding their respective 2L Standards. Samples from the wells showed general decreases in total BTEX concentrations in wells MW‐5 and MW‐10. Increases in total BTEX compounds were shown in the remaining wells, with the increases in MW‐2R appearing substantial.  October 2019 ‐ WR completed a limited groundwater sampling event at the facility. Analytical results for the groundwater samples obtained from site monitoring wells on October 14, 2019 showed one or more petroleum compounds in each of the wells sampled (with the exception of MW‐3) at concentrations exceeding their respective 2L Standards. No contaminants were reported at concentrations exceeding their respective GCLs. Based on October 2019 data for groundwater samples obtained from site monitoring wells, a general increase (based solely on total BTEX concentrations) was seen over the July 2019 data in monitoring wells MW‐2R (134%), MW‐11 (191%) and MW‐13 (3% increase). The increase in total BTEX in MW‐2R and MW‐11 appear significant, however, WR surmises that these increases relate to the “liberation” of chemical compounds previously bound to soils at the location as a result of the emplacement of the RemRX™ CRP following soil excavation at the site. Moderate reductions of BTEX compounds were seen in MW‐5, MW10 and MW‐12, while a slight decrease was seen in MW‐8.  January 2020 ‐ WR completed a limited groundwater sampling event at the facility. Analytical results for the groundwater samples obtained from site monitoring wells on January 8, 2020 showed one or more petroleum compounds in wells MW‐2R, MW‐10, MW‐11 and MW‐13 at concentrations exceeding their respective 2L Standards. No contaminants were reported at concentrations exceeding their respective GCLs. Based on October 2019 data for groundwater samples obtained from site monitoring wells, a substantial decrease (based solely on total BTEX concentrations) was seen over the October 2019 data in monitoring wells MW‐ 5 (95%), MW‐8 (100%), MW‐11 (60%) and MW‐12 (100%), while a moderate decrease of 26% was seen in MW‐13. Levels of total BTEX in MW‐10 showed a 22% increase over the same period. The increase in total BTEX in MW‐10 likely relate to the “liberation” of chemical compounds previously bound to soils at the location as a result of the emplacement of the RemRX™ CRP following soil excavation at the site.  February 2020 ‐ WR completed a site‐wide groundwater sampling event at the facility. One or more targeted compounds were reported in samples from MW‐1, MW‐2R, MW‐3, MW‐5, MW‐7, MW‐10, MW‐12 and MW‐13. One or more of the compounds detected in samples from MW‐2R, MW‐10, MW‐12 and MW‐13 were reported at levels exceeding their respective 2L Standards. No targeted compounds were reported at concentrations exceeding heir respective GCLs. WR obtained a supply well sample from WSW‐3 following purging of the well. Laboratory results for the sample obtained from supply well WSW‐3 in February 2020 WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 9 indicated bromodichloromethane and dibromochloromethane at concentrations above their respective 2L Standards. Chloroform was also reported in the sample, however, the concentration detected was beneath the 2L Standard for the compound. WR believes the presence of each compound reported in the sample relates to the shock‐chlorination of the supply well.  November 2020 – WR completed a limited groundwater sampling event at the site. Analytical results for the groundwater samples obtained from site monitoring wells on November 18, 2020 showed one or more petroleum compounds in wells MW‐2R, MW‐10, MW‐11 and MW‐ 13 at concentrations exceeding their respective 2L Standards. No contaminants were reported at concentrations exceeding their respective GCLs. Based on November 2020 data for groundwater samples obtained from site monitoring wells, substantial decreases (based solely on total BTEX concentrations) were seen over the February 2020 data in monitoring wells MW‐2R (53%), MW‐10 (83%), MW‐12 (27%) and MW‐13 (32%). Levels of total BTEX in MW‐ 5 showed a 1,734% increase over the same period, but on‐scale this increase does not appear significant.  February 2021 – WR completed an annual groundwater and supply well sampling event at the site. Laboratory results for groundwater samples obtained from site monitoring wells showed impact by petroleum compounds at concentrations exceeding their respective 2L Standards in samples from monitoring wells MW‐2R, MW‐10 and MW‐13. 1,2‐Dibromoethane was reported in the sample from MW‐2R at a level exceeding the GCL for the compound. Results of persulfate analysis of groundwater samples obtained from select monitoring wells showed concentrations of persulfate in monitoring wells MW‐2R (53 mg/L), MW‐10 (32 mg/L) and MW‐13 (16 mg/L). These data suggest persulfate emplaced in association with remedial action at the site is migrating with groundwater flow and has shown depletion over time. Laboratory results for a sample obtained from supply well WSW‐3 in February 2021 did not indicate the presence of targeted chemical compounds by SM6200B.  May 2021 – WR Oversaw the completion of additional remedial activities at the location including the installation of a total of eighteen (18) “injection borings” (IP‐1 through IP‐18). These activities are discussed in Section E, below.  December 2021 – WR completed an annual groundwater and supply well sampling event at the site. One or more targeted compounds were reported in samples from MW‐2R, MW‐5, MW‐8, MW‐10, MW‐11, MW‐12 and MW‐13 at concentrations exceeding their 2L Standards. No compounds were reported at levels exceeding their GCLs. Phosphorous was reported in samples obtained from MW‐2R, MW‐5, MW‐8, MW‐10, MW‐11, MW‐12 and MW‐13. No current 2L Standard exists for phosphorous in groundwater. Total iron (Fe) was reported in each of the samples analyzed by SM6010C. Levels of the element ranged from 3,080 µg/L (MW‐5) to 926,000 µg/L (MW‐11). Levels of iron in all of the samples submitted for SM6010C testing were reported above the 2L Standard for the element. Manganese was reported in each of the samples analyzed by SM6010C. Concentrations of the element reported in MW‐ 2R, MW‐8, MW‐10, MW‐11 and MW‐13 were at levels in excess of the 2L Standard. Sulfate was reported in each of the samples submitted for analysis by SM9056A. Levels of sulfate reported in samples ranged from 5,480 µg/L (MW‐8) to 4,930,000 µg/L (MW‐11). Levels of sulfate detected in the samples from MW‐2R, MW‐10, MW‐11 and MW‐13 exceeded the 2L Standard. Laboratory results for the sample obtained from supply well WSW‐3 in December 2021 showed bromodichloromethane and dibromochloromethane present at levels exceeding their 2L Standards. Chloroform was also reported in the sample obtained from WSW‐3, WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 10 however, the concentration detected was beneath the 2L Standard for the compound. Each of these compounds are typical byproducts of “shock chlorination” of water wells, and WR attributes their presence in WSW‐3 to this process.  June 2022 ‐ WR completed a semi‐annual groundwater sampling event at the site. Laboratory results for groundwater samples obtained from site monitoring wells during June 2022 showed impact by petroleum compounds at concentrations exceeding their respective 2L Standards in samples from monitoring wells MW‐2R, MW‐5, MW‐8, MW‐10, MW‐11, MW‐12 and MW‐ 13. No compounds were reported at levels exceeding their GCLs. Total BTEX concentrations reported in source area well MW‐2R in June 2022 showed a 177% increase over data from December 2021, likely owed to fluctuations in groundwater elevations over the period and “washing” of contaminants from remaining impacted soils through increased contact with persulfate emplaced as a part of initial abatement actions in March/April 2019, augmented through emplacement of added materials in May 2021. General increases in contaminants were observed in other wells (MW‐8, MW‐10, MW‐12 and MW‐13). Data for wells MW‐5 and MW‐11 showed decreases (46% and 96%, respectively) in total BTEX concentrations over the December 2021 data. Phosphorous was reported in samples obtained from MW‐2R, MW‐ 3, MW‐5, MW‐8, MW‐10, MW‐11, MW‐12 and MW‐13. No current 2L Standard exists for phosphorous in groundwater. Total iron was reported in each of the samples analyzed by SM6010C. Levels of the element ranged from 8,620 µg/L (MW‐3) to 545,000 µg/L (MW‐11). Levels of iron in all of the samples submitted for SM6010C testing were reported above the 2L Standard for the element. Manganese was reported in each of the samples analyzed by SM6010C. Concentrations of the element in each of the samples were reported at levels in excess of the 2L Standard. Sulfate was reported in each of the samples submitted for analysis by SM9056A. Levels of sulfate reported in samples ranged from 8,910 µg/L (MW‐5) to 3,140,000 µg/L (MW‐11). Levels of sulfate detected in the samples from MW‐2R, MW‐11 and MW‐13 exceeded the 2L Standard.  January 2023 ‐ WR completed a semi‐annual groundwater sampling event at the site. Laboratory results for groundwater samples obtained from site monitoring wells during January 2023 showed impact by petroleum compounds at concentrations exceeding their respective 2L Standards in samples from monitoring wells MW‐2R, MW‐8, MW‐10, MW‐11, and MW‐13. No compounds were reported at levels exceeding their GCLs. Total BTEX concentrations reported in source area well MW‐2R in January 2023 showed a 38% decrease over data from June 2022 and a 25% decrease in MW‐10 over the same period. Overall, general decreases in contaminants were observed in remaining wells in which contaminants were identified, with the exception of MW‐12 and MW‐13. Data for wells MW‐12 and MW‐ 13 showed increases (111% and 165%, respectively) in total BTEX concentrations over the June 2022 data, however, these increases are not thought to be significant based on the relatively low levels of contaminants identified in the wells. Phosphorous was reported in samples obtained from MW‐2R, MW‐5, MW‐8, MW‐10, MW‐11, MW‐12 and MW‐13. No current 2L Standard exists for phosphorous in groundwater. Total iron (Fe) was reported in each of the samples analyzed by SM6010C. Levels of the element ranged from 2,270 µg/L (MW‐3) to 1,140,000 µg/L (MW‐5).

Brief Description of Site Characteristics The site is located in Tarboro, Edgecombe County, North Carolina (Figure 1) at 5070 Howard Avenue Extension and includes the following improvements: A one‐story brick/block structure (Figure 2), surrounded by areas of grass and gravel. The site formerly operated as a convenience store but has ceased operations. The NCPIN No. for the property is 4708‐94‐7721. The surrounding area consists of private residences, farming land and undeveloped properties. Municipal water is currently available to the site and surrounding locations, and is utilized as a potable water source for all surrounding properties, with the exception of a single property located approximately 500 feet west of the source area on the site. 4. Information on Receptors/Potential Receptors A receptor survey update was performed in association with the release at the site by ATC Associates in December 2006 and included the following findings:  Seven water supply wells were identified within 1,000 feet of the site,  The Edgecombe County public water supply was found to be available to the site and surrounding properties.  Pender’s Mill Run was identified to lie “750 feet east of the site”. As a part of the receptor survey update performed in April 2015, WR identified the presence of ten water supply wells within 1,000 feet of the source area on the site. Of these wells, one (WSW‐ 4) was found to be utilized as an active, potable water supply; Three (WSW‐3, WSW‐5 and WSW‐ 8) were found to be utilized as non‐potable water supplies, and six (WSW‐1, WSW‐2, WSW‐5A, WSW‐7, WSW‐8A and WSW‐9) were found to be inactive. Information relating to supply wells identified through the performance of the receptor survey are included in Table B‐5A. Locations of supply wells located in proximity to the site are depicted on Figure 6. The owner/user of WSW‐3 (Mr. Claudius Barnes) was approached by NCDEQ in 2015 in an attempt to allow for the abandonment of this well. Mr. Barnes indicated he would agree to the well’s abandonment, provided NCDEQ would reimburse him for the cost of the installation of the well. NCDEQ declined to enter into an agreement with Mr. Barnes based on this condition. A freshwater tributary of the Tar River (Pender’s Mill Run) approaches to within 800 feet northeast of the release area on the site. Additional receptors are included in Table B‐5B, and also shown on Figure 7. No community water supply wells or wellhead protection areas were identified within 1,500 feet of the source area. Potable water is available from the Edgecombe County water supply system and in use at the site and surrounding properties, with the exception of the location of WSW‐4. The owner/user of WSW‐4 has repeatedly denied past WR requests to obtain samples from the supply well. WithersRavenel Our People. Your Success.

INITIAL ABATEMENT ACTION – MARCH 29 – APRIL 19, 2019 Prior to excavation activities performed as an Initial Abatement Action, Ready removed the concrete island and concrete and asphalt surface covering overlying area targeted for soil excavation. In an effort to remove as much grossly impacted soil (relating to the known release at the facility) as feasible, the NCDEQ Incident Manager (Mr. Mark Petermann) directed that excavation of contaminated soils be performed, focusing on the removal of soils underlying the pump island, extending to a depth which intersected the surficial aquifer beneath the location. WR oversaw the excavation of a total of 246.87 tons of impacted material to remove petroleum contaminated soils in the vicinity of the pump island, including those underlying the former pump island location to an average depth of approximately 8 ft beneath grade, contacting the surficial aquifer. Excavation activities were performed using a trackhoe, which removed impacted soils and loaded those soils directly into waiting dump trucks. The excavation was limited laterally to an area assessed by previous consultants from just west of the former pump island extending approximately 20 ft to the east. The final excavated area measured approximately 23 ft by 24 ft by 8 ft deep (average depth). WR monitored excavation activities by screening discreet soil samples with a MiniRAE 3000 Photo Ionization Detector (PID) for the presence of volatile vapors typical of petroleum hydrocarbons. Soils excavated from the location were ‘live‐loaded” into dump trucks through the use of a trackhoe and transported from the site for treatment and/or disposal by Soilworks, Inc., an NCDEQ permitted soil remediation facility located in Selma, NC. Following removal of contaminated soils and prior to backfilling, materials were emplaced in contact with groundwater to facilitate oxidative degradation of petroleum contaminants in site groundwater. These materials included 462 pounds of RemRX™ CRP (controlled Release Pellets) Persulfate, 440 pounds of fast release persulfate and 55 pounds of Iron activator. After emplacement, the materials were hydrated to ensure good contact with groundwater and mixed into the upper surface of the soil/groundwater interface with the trackhoe. Following emplacement of the persulfate and activator, the excavated area was backfilled with clean fill material originating from an off‐site source. Fill materials were emplaced and compacted using the trackhoe. Soil fill was emplaced to within approximately 6‐inches of surface grade, and the remainder of the excavation was finished at surface grade with crush and run gravel material, which was leveled and compacted with the trackhoe. WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 13 Ongoing assessment of the release on the property is being performed under the NCDEQ‐UST Section Federal & State Lead Cleanup Program. The premise of over‐excavation of contaminated soils in the vicinity of the pump island was to remove as much impacted media as possible, thus serving as a source area reductive measure, while understanding that saturated contaminated soils would be left in‐place. Emplacement of persulfate was performed to facilitate oxidative degradation of groundwater contaminants, which will be measured/monitored through future testing. Sidewall (confirmatory) soil samples were collected at the conclusion of soil over‐excavation. These confirmatory samples were collected from the bucket of the tracked excavator, field screened and placed in laboratory prepared containers. WR personnel donned clean nitrile sampling gloves for each sample location. Samples were collected from the sidewalls of the over‐ excavated area at depths of approximately 6 to 7 ft below land surface (just above groundwater at the location). Confirmatory samples were submitted for fixed‐based analysis of VOCs by EPA Method 8260B. Analytical data for samples obtained from excavation sidewalls of the excavated area showed the following: EPA Method 8260 – One or more targeted compounds were reported in samples SW‐1, SW‐3, SW‐6 and SW‐7. Several compounds (in addition to benzene) were identified in sample SW‐3 at concentrations exceeding their respective Soil to Water MSCCs. Benzene was also identified in sidewall samples SW‐6 and SW‐7 at levels above the Soil to Water MSCC. WR returned to the site on March 18, 2019 for the purposes of installing a replacement well for MW‐2. This well (MW‐2R) was installed by Quantex, Inc. using a track‐mounted GeoProbe™ rig employing 6.25‐inch (in) outside diameter (OD) hollow‐stem augers. The well was advanced to a total depth of 20 ft beneath surface grade. The well was set with 15 ft of 2 in OD PVC well screen and a 5 ft PVC riser. Clean washed well sand was emplaced surrounding the well screen extending a minimum of 1 ft above the screened section. This was capped by a minimum of 1 ft of bentonite above the sand pack, and completed with an 8 in dia flush mounted steel manhole encased in concrete and a locking well cap.

CORRECTIVE ACTION ACTIVITIES – MAY 2021 On May 3, 2021 WR personnel mobilized to the subject site to perform corrective action activities in accordance with task authorization TA‐03 under NCDEQ Contract # N70522‐C. Activities included those outlined below: 1 Permitting Prior to the implementation of corrective action activities as outlined below, WR completed a Notification of Intent (NOI) ‐ “Deemed as Permitted” application for submittal to the NCDEQ – Division of Water Resources (DWR) to permit the emplacement of chemical additive in locations intersecting and beneath site groundwater. Following submittal of the NOI, NCDEQ‐DWR Deemed Permit Number WI0501075 was issued through email on April 16, 2021. 2 Boring Installations and Amendment Emplacement WR supervised the installation of a total of eighteen (18) “injection borings” (IP‐1 through IP‐18) on the site between the dates of May 3 and 6, 2021. These borings were installed utilizing 4¾” inside diameter (ID) hollow‐stem augers. Borings were installed by Quantex, Inc., of Wendell, NC with a GeoProbe® DPT™ mobile drill rig. Borings were advanced to depths of 20‐ft beneath surface grade, penetrating and extending into the groundwater on the site, so as to allow the introduction of chemical amendments as backfill materials. After advancing each boring to target depths, the augers were removed in 5‐ft sections and chemical amendments including RemRx Controlled‐Release Persulfate (CRP), fast acting sodium persulfate and iron ethylenediaminetetraacetic acid (EDTA) – included as an “activator” were emplaced into the annulus of the borings. Dosing of these materials was based on design by a RemRx scientist, present on the site during emplacement activities. Actual locations of borings were altered from the initial design so as to target contaminated groundwater within the primary source area on the property. Following the installation of the borings and emplacement of remedial materials, each was backfilled with bentonite and native soils to match original grade. Installation, dosing and backfilling of the borings were completed between May 3 and 6, 2021. WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 15 SECTION F. MONITORING WELL & SUPPLY WELL SAMPLING –JULY 2023 WR conducted a site‐wide groundwater monitoring event at the in association with TA‐01 under NCDEQ Contract #N70522‐C. These activities are described below. WR mobilized to the site on July 27, 2023for the purposes of completing a site‐wide groundwater sampling event. Prior to the purging and sampling of site monitoring wells as described below, WR personnel opened and gauged each well with an electronic water level indicator to determine the depth to. In the performance of these activities, free product was not measured in any of the monitoring wells on the site. The depth to groundwater measurements in the monitoring wells ranged from 8.27‐feet below the top of casing (ft‐BTOC) in monitoring well MW‐7 to 11.69 ft‐BTOC in monitoring well MW‐ 3. Groundwater elevations site‐wide averaged 0.42‐ft deeper than those obtained in January 2023. Based on groundwater elevation measurements from July 27, 2023, groundwater flow appears to trend generally to the east through the site. Groundwater hydraulic gradient as determined based on these measurements is shown on Figure 3. Groundwater elevation measurement data for this event are presented in Table B‐7. The groundwater flow appears to be somewhat consistent with the direction of historical groundwater flow. Historical groundwater elevations are included in Table B‐9. Monitoring Well Sampling WR personnel obtained groundwater samples from MW‐1, MW‐2R, MW‐3, MW‐4, MW‐5, MW‐ 6, MW‐7, MW‐8, MW‐9, MW‐10, MW‐11, MW‐12 and MW‐13 following gauging and purging. Each well was purged with separate, disposable bailers as described in the procedures outlined in Appendix C. Prior to the sampling of each well, water quality measurements were recorded. Water quality measurements obtained while purging the wells were recorded in field notes, copies of which are included in Appendix B. Following purging, groundwater samples were decanted directly from dedicated bailers into laboratory prepared sample containers holding appropriate preservative(s) as required. Groundwater samples were submitted to Waypoint Analytical, LLC (Waypoint) for analysis by SM6200B (VOCs). The laboratory analytical report and chain‐of‐custody record associated with these samples are included in Appendix A. WithersRavenel Our People. Your Success.

Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 19 Based on the July 2023 groundwater sampling event performed at the site, the extent of groundwater contamination appears adequately defined. Contaminant concentrations appear to decrease appreciably with distance from the source area on the site. While fluctuations in contaminant levels (based on total BTEX concentrations) have occurred over the January – July 2023 period, current data shows that marked decreases in contaminants have occurred since remedial actions were completed. Total BTEX concentrations reported in source area well MW‐ 2R in January 2023 showed a 56% decrease over data from January 2023 and a 10% increase in MW‐10 over the same period.

The laboratory analytical report and chain‐of‐custody record associated with these samples are included in Appendix A. Supply Well Sampling – WSW‐3 WR personnel obtained samples from supply well WSW‐3, located on the adjacent northern property following purging. The well was purged by energizing the associated well pump and allowing flushing of water through the pump for a period of at least 10‐minutes. Following adequate purging, samples were decanted directly from the sampling point into laboratory prepared sample containers holding appropriate preservative(s) as required. The sample from WSW‐3 was submitted to Waypoint for analysis by SM6200B. The laboratory analytical report and chain‐of‐custody record associated with the sample is included in Appendix A. Laboratory Analytical Results Testing of the sample obtained from WSW‐3 on July 27, 2023 indicated the following: SM6200B (VOCs) Laboratory results for the supply well sample obtained from WSW‐3 showed naphthalene present at a level beneath the NC 2L Standard. Based on laboratory results dating back to July 2014, this is the first instance in which a petroleum compound has been identified in the well. As this compound does not appear in samples from MW‐3 (located between the source area and WSW‐ 3, the presence of the compound may not relate to the release on the Batts Grocery site. WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 21 SECTION G. CONCLUSIONS AND RECOMMENDATIONS This report documents the evaluation of corrective action performance and annual groundwater monitoring at the site following the excavation of petroleum contaminated soils and emplacement of a chemical amendment in vadose zone soils within the excavated area. Information obtained during follow‐up sampling activities combined with historical information indicate the following:  Excavation of petroleum impacted soils and the backfilling of a portion of the excavation with RemRx™ CRP® slow‐release persulfate is generally showing fluctuation of total BTEX concentrations in all monitoring wells associated with the site. Total BTEX concentrations reported in source area well MW‐2R in December 2021 showed an 86% decrease over data from February 2021, likely owed to fluctuations in groundwater elevations over the period and “washing” of contaminants from remaining impacted soils through increased contact with persulfate emplaced as a part of initial abatement actions in March/April 2019, augmented through emplacement of added materials in May 2021.  Laboratory results for groundwater samples obtained from site monitoring wells during July 2023 showed impact by petroleum compounds at concentrations exceeding their respective 2L Standards in samples from monitoring wells MW‐2R, MW‐5, MW‐8, MW‐10, MW‐11, and MW‐13. No compounds were reported at levels exceeding their GCLs.  Based on the July 2023 groundwater sampling event performed at the site, the extent of groundwater contamination appears adequately defined.  While fluctuations in contaminant levels (based on total BTEX concentrations) have occurred over the January – July 2023 period, current data shows that marked decreases in contaminants have occurred since remedial actions were completed.  Total BTEX concentrations reported in source area well MW‐2R in January 2023 showed a 56% decrease over data from January 2023 and a 10% increase in MW‐10 over the same period.  Overall, general decreases in contaminants were observed in remaining wells in which contaminants were identified, with the exception of MW‐5.  Data for wells MW‐12 and MW‐13 showed decreases (68% and 80%, respectively) in total BTEX concentrations over the January 2023 data.  Based on groundwater level measurements obtained during the July 2023 sampling event, the direction of groundwater flow is easterly towards Pender’s Mill Run, a tributary of the Tar River. Pender’s Mill‐Run approaches to within 800 feet to the east of the source area. The general direction of groundwater flow is consistent with previous interpretations of flow direction.  Laboratory results for the supply well sample obtained from WSW‐3 (non‐potable) showed naphthalene present at a level beneath the NC 2L Standard. Based on laboratory results dating back to July 2014, this is the first instance in which a petroleum compound has been identified in the well. As this compound does not appear in samples from MW‐3 (located between the source area and WSW‐3, the presence of the compound may not relate to the release on the Batts Grocery site. WithersRavenel Our People. Your Success. Batts Grocery WR Project # 23‐0307‐AB Corrective Action Performance Report (Subsequent) August 2023 22 Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  Continued monitoring of site groundwater conditions through semi‐annual monitoring.  Annual sampling of supply well WSW‐3.

Your Success. Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations.

Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using an electronic oil/water interface probe. The interface probe has both an audible and illuminating light that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination or field personnel exposure to contaminants. Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device. Screening of samples with a PID, FID or other field screening device is performed in accordance with device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a dedicated, disposable bailer, a peristaltic pump or submersible electric pump. When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging. When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre- preserved container(s) provided by the laboratory. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is contained in laboratory grade sample containers as described in the previous section. Water quality parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or electric submersible pump.

Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon the method(s) of sampling performed at any site, but will generally include the following: • Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary, • Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),  Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry, • Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary prior to their use in sampling.
