(Altec) for the closure of a non-regulated noncommercial heating oil underground storage tank (UST) and subsequent site investigation at the property located at 640 Rock Lane in China Grove, Rowan County, North Carolina (the “subject property”). The subject property is located on the northern portion of a larger parent tract that encompasses approximately 17.07 acres. The subject property contains one vacant residential structure and a detached garage. The location of the subject property is depicted on Figure 1. UST REMOVAL On March 17, 2023, ONE mobilized to the site with a UST removal contractor, Clean Safe Technologies (CST), to excavate and remove one approximate 270-gallon former heating oil UST from the subject property. At the time of removal, there was no product inside the tank; however, the tank did contain approximately 5-6 inches of water. Upon removal, the UST was observed to be in poor condition with several holes and cracks around the bottom. The UST was cut in half, cleaned, and transported by CST to a salvage yard for destruction. A copy of the Certificate of Recycling is provided as Attachment A. Soil within the UST excavation was screened using a photoionization detector (PID). Elevated PID readings up to 15,000 parts per million (ppm) were detected in soil below the UST down to a depth of approximately 10 feet below ground surface (bgs), which was the maximum depth of the excavation equipment. Due to the significantly elevated PID readings at the bottom of the excavation, a soil sample was not collected for laboratory analysis. Mr. Bruce Stainbrook July 25, 2023 Page 2 of 7 ONE Environmental Mid Atlantic, LLC www.oneenv.com The excavated soil was temporarily staged on-site and covered with plastic, and orange construction fencing was placed around the excavation until it could be backfilled with clean soil. On March 27, 2023, CST returned to the subject property to haul off the impacted soil and backfill the excavation with clean soil. Approximately 5 tons of petroleum-impacted soil was transported to HAZ-MAT Environmental Services in Charlotte, North Carolina for disposal. A copy of the waste disposal manifest is provided as Attachment B. INVESTIGATIVE PROCEDURES Prior to the introduction of the soil borings, the North Carolina 811 notification system for excavators, contractors, property owners, and drillers was contacted as required by state law to notify participating utilities of the upcoming work, so they could locate and mark their underground facilities. Soil Investigation On April 6-7, 2023, under the direction of ONE, M&W Drilling LLC (MWD) advanced nine soil borings (EB-1 through EB-9) at the subject property using direct push technology (DPT). Environmental boring EB-1 was placed in the location of the former UST and the remaining eight borings surrounded EB-1 in a 15-foot grid pattern. The soil boring locations are depicted on Figure 2. The soil borings were advanced to depths ranging from 20-35 feet below ground surface (bgs). Soil samples obtained from the soil borings were field screened visually and with a PID. Soil samples for laboratory analysis were selected based on the field screening results. The PID results and visual observations of the soil samples are documented on the soil boring logs provided as Attachment C. The soil samples were placed in clean laboratory-supplied containers and sent under proper chain-of custody documentation to Eurofins in Pittsburg, Pennsylvania for analysis of the following:  Volatile organic compounds (VOCs) by EPA Method 8260  Semivolatile organic compounds (SVOCs) by EPA Method 8270  Volatile petroleum hydrocarbons (VPHs) by Massachusetts Department of Environmental Protection (MADEP) Methods  Extractable petroleum hydrocarbons (EPHs) by MADEP Methods Supplemental Soil Investigation ONE returned to the subject property on May 30-31, 2023, to collect additional soil samples and delineate soil impacts detected during the April 2023 sampling event. Under the direction of ONE, Mr. Bruce Stainbrook July 25, 2023 Page 3 of 7 ONE Environmental Mid Atlantic, LLC www.oneenv.com MWD advanced ten soil borings (EB-6B, EB-7B, and EB-10 through EB-17) at the subject property using direct push technology. With the exceptions of EB-16 and EB-17, which were advanced near the former residence to the east, the soil boring locations continued to follow the previous 15-foot grid pattern. Environmental borings EB-6B and EB-7B were advanced to investigate the vertical distribution of substances detected during the April 2023 sampling event. The additional soil boring locations are depicted on Figure 2. The additional soil borings were advanced to depths ranging from 5-20 feet bgs. Soil samples obtained from the soil borings were field screened visually and with a PID. Soil samples for laboratory analysis were collected from EB-6B and EB-7B at predetermined depths of 3-5 feet bgs and 8-10 feet bgs, respectively. The remaining soil samples for laboratory analysis were selected based on the field screening results. The PID results and visual observations of the soil samples are documented on the soil boring logs provided as Attachment C. The soil samples were placed in clean laboratory-supplied containers and sent under proper chain-of custody documentation to Eurofins in Pittsburg, Pennsylvania for analysis of the following:  VOCs by EPA Method 8260  SVOCs by EPA Method 8270  VPHs by MADEP Methods  EPHs by MADEP Methods Groundwater Investigation On April 6, 2023, under the direction of ONE, MWD installed three temporary monitoring wells (TMW-1 through TMW-3) at the subject property to evaluate potential groundwater impacts relating to the former UST. Temporary monitoring well TMW-1 was installed in the location of the former UST with TMW-2 and TMW-3 approximately 30 feet to the west and south, respectively. The well locations are depicted on Figure 3. The temporary monitoring wells were constructed by inserting a 20-foot section of 1-inch diameter polyvinyl chloride (PVC) slotted screen in the 2-inch diameter borehole created by the DPT rods. One-inch PVC riser pipe extended from the top of the screen to at least 1 foot above the ground surface. The temporary monitoring wells were capped with lockable rubber stoppers and left in place to facilitate future sampling, if necessary. ONE returned to the site on April 12, 2023, to sample the temporary monitoring wells. The wells were developed utilizing a peristaltic pump with new polyethylene and silicone tubing until at least Mr. Bruce Stainbrook July 25, 2023 Page 4 of 7 ONE Environmental Mid Atlantic, LLC www.oneenv.com three well volumes had been removed from the well and limited fines were observed in the development water. The groundwater samples were placed in clean laboratory-supplied containers and sent under proper chain-of custody documentation to Eurofins in Pittsburg, Pennsylvania for analysis of the following:  VOCs by EPA Method 8260  SVOCs by EPA Method 625.1  VPHs by MADEP Methods  EPHs by MADEP Methods Supplemental Groundwater Investigation On May 30-31, 2023, under the direction of ONE, MWD installed seven additional temporary monitoring wells (TMW-4 through TMW-10) at the subject property to further evaluate potential groundwater impacts relating to the former UST. The well locations are depicted on Figure 3. Except for TMW-8, the temporary monitoring wells were constructed by inserting 5 to 10-foot sections of 1-inch diameter PVC slotted screen in the 2-inch diameter boreholes created by the DPT rods. One-inch PVC riser pipe extended from the top of screens to at least 1 foot above the ground surface. The temporary monitoring wells were capped with lockable rubber stoppers and left in place to facilitate future sampling, if necessary. Please note that temporary monitoring well TMW-8 was located in the driveway and could not be left in place; therefore, a stainless-steel screenpoint sampler with a 4-foot section of stainless-steel slotted screen was used to collect a groundwater sample. Following sample collection, the screenpoint sampler was immediately removed from the ground by MWD and the borehole properly abandoned. Between May 30, 2023 and June 1, 2023, ONE collected groundwater samples from all ten on-site monitoring wells. The wells were developed utilizing a peristaltic pump with new polyethylene and silicone tubing until at least three well volumes had been removed from the well and limited fines were observed in the development water. The groundwater samples were placed in clean laboratory-supplied containers and sent under proper chain-of custody documentation to Eurofins in Pittsburg, Pennsylvania for analysis of the following:  VOCs by EPA Method 8260  SVOCs by EPA Method 625.1 Mr. Bruce Stainbrook July 25, 2023 Page 5 of 7 ONE Environmental Mid Atlantic, LLC www.oneenv.com  VPHs by MADEP Methods  EPHs by MADEP Methods In addition to collecting groundwater samples, ONE obtained relative top of casing (TOC) elevations from all on-site temporary monitoring wells, except for TMW-8. Further, depth to groundwater measurements were collected from the entire well network on June 1, 2023 using an electronic water level indicator accurate to 0.01 foot. INVESTIGATIVE RESULTS Soil Investigation Results The laboratory analytical results for the soil samples collected at the subject property were compared to the North Carolina Department of Environmental Quality (NCDEQ) Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs) and Residential MSCCs, whichever was lower, per 15A NCAC 02L .0411. One VOC (1,1,1-trichloroethane) was detected above the laboratory reporting limit in soil at the subject property; however, the concentrations of 1,1,1-trichloroethane were less than the applicable MSCC. Five SVOCs (benzo[a]anthracene, chrysene, fluoranthene, phenanthrene, and pyrene) were detected above laboratory reporting limits in soil at the subject property; however, the concentrations of these SVOCs were less than the applicable MSCCs. Two MADEP VPHs (C9-C12 aliphatics and C9-C10 aromatics) were detected above laboratory reporting limits in soil at the subject property. While the concentrations of C9-C12 aliphatics were below the applicable MSCCs, the concentrations of C9-C10 aromatics detected in both soil samples collected from EB-12 (2-4 feet bgs and 6-8 feet bgs) exceeded the Soil-to-Groundwater MSCC. Three MADEP EPHs (C9-C18 aliphatics, C19-C36 aliphatics, and C11-C22 aromatics) were detected above laboratory reporting limits in soil at the subject property. While the concentrations of C9-C18 aliphatics and C19-C36 aliphatics were below the applicable MSCCs, the concentrations of C11-C22 aromatics detected in the soil samples collected from EB-7 (3-5 feet bgs) and EB-12 (2-4 feet bgs) exceeded the Soil-to-Groundwater MSCC. The soil analytical results are summarized in Table 1. The complete laboratory analytical data reports are provided as Attachment D. Groundwater Investigation Results Mr. Bruce Stainbrook July 25, 2023 Page 6 of 7 ONE Environmental Mid Atlantic, LLC www.oneenv.com The laboratory analytical results for the groundwater samples collected at the subject property were compared to the NCDEQ Groundwater Quality Standard (GWQS) per 15A NCAC 02L .0202. Three VOCs (benzene, toluene, and xylenes) were detected above laboratory reporting limits in groundwater at the subject property. While the concentrations of toluene and xylenes were below the GWQSs, the concentrations of benzene detected in the groundwater samples collected from temporary monitoring wells TMW-1 and TMW-3 exceeded the GWQS. Three SVOCs (1-methylnaphthalene, 2-methylnaphthalene, and naphthalene) were detected above laboratory reporting limits in groundwater at the subject property; however, the concentrations of these SVOCs were less than the GWQSs. Two MADEP VPHs (C5-C8 aliphatics and C9-C12 aliphatics) were detected above laboratory reporting limits in groundwater at the subject property; however, the concentrations of these MADEP VPHs were less than the GWQSs. Two MADEP EPHs (C9-C18 aliphatics and C11-C22 aromatics) were detected above laboratory reporting limits in groundwater at the subject property; however, the concentrations of these MADEP EPHs were less than the GWQSs. The groundwater analytical results are summarized in Table 2. The complete laboratory analytical data reports are provided as Attachment D. Based on the water table elevations measured on June 1, 2023, the groundwater flow directions in the vicinity of the former UST appear to be to the west, southwest, and south. The water table contours and estimated groundwater flow directions are depicted on Figure 4. CONCLUSIONS AND RECOMMENDATIONS ONE collected 20 soil samples at the subject property over the course of two site visits. C11-C22 aromatics exceeded the Soil-to-Groundwater MSCC in the soil sample collected from EB-7 (2-4 feet bgs); however, a deeper soil sample collected at this location from EB-7B (8-10 feet bgs) did not exhibit any MSCC exceedances. Similarly, C11-C22 aromatics exceeded the Soil-to-Groundwater MSCC in the shallow soil sample collected from EB-12 (2-4 feet bgs) but were below the MSCC in the deeper soil sample (6-8 feet bgs). On the other hand, C9-C10 aromatics exceeded the Soil-to-Groundwater MSCC in both the shallow and deep soil samples collected from EB-12; however, it should be noted the concentration of C9-C10 aromatics in EB-12 (6-8 feet bgs) was 32.8 milligrams per kilogram (mg/kg), which is only slightly above the Soil-to-Groundwater MSCC of 31 mg/kg. To summarize, while MSCC exceedances were detected at the subject property, the soil impacts appear to be relatively minor. Mr. Bruce Stainbrook July 25, 2023 Page 7 of 7 ONE Environmental Mid Atlantic, LLC www.oneenv.com Benzene was the only compound detected at the subject property above the GWQS. The maximum concentration of benzene (21.4 micrograms per liter [µg/L]) was detected in TMW-1, which is in the location of the former UST. Benzene was also detected above the GWQS in the groundwater sample collected from TMW-3, which is located approximately 30 feet to the south of the former UST. This is consistent with the findings of the groundwater flow direction at this location, which is to the south. The concentration of benzene in TMW-3 was 2 µg/L in the sample collected on May 31, 2023, but it was below the laboratory reporting limit in the sample collected on April 12, 2023. This suggests that the concentration of benzene in TMW-3 fluctuates around the GWQS for benzene of 1 µg/L. Like soil, the groundwater impacts at the subject property appear to be relatively minor and do not appear to be migrating significantly. Moreover, the groundwater flow direction and analytical data suggest that the release at the subject property is not expected to impact the adjoining property to the north.

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.3°C GC/MS VOA Method 8260D: The continuing calibration verification (CCV) analyzed in 180-432477 was outside the method criteria for the following analyte(s): Dichloro-difluoromethane and Methyl acetate (HIGH). As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-432477 was outside the method criteria for the following analyte(s): Chloromethane, 1,2-Dibromo-3-Chloropropane, 1,1,2-Trichloroethane, 2-Hexanone and 4-Methyl-2-pentanone (LOW). A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-432477 was outside the method criteria for the following analyte(s): 1,2-Dibromo-3-Chloropropane (RF). A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. Method 8260D: The laboratory control sample (LCS) for analytical batch 180-432477 recovered outside control limits for the following analytes: Dichloro-difluoromethane and Methyl acetate. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260D: The laboratory control sample duplicate (LCSD) for analytical batch 180-432477 recovered outside control limits for the following analytes: Dichloro-difluoromethane and Methylene Chloride. These analytes were biased high in the LCSD and were not detected in the associated samples; therefore, the data have been reported. Method 8260D: Surrogate recovery for the following sample was outside the upper control limit: EB-1 (8-10) (180-154769-1). This sample did not contain any target analytes; therefore, re-extraction and/or re-analysis was not performed. Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-432752 was outside the method criteria for the following analyte(s): Acetone, 2-Hexanone and 2-Butanone (LOW).

As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. Method 8260D: The continuing calibration verification (CCV) analyzed in 180-432752 was outside the method criteria for the following analyte(s): Methyl acetate, Dichloro-difluoromethane and 1,1,2-Trichloro-1,2,2-trifluoroethane (HIGH). As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. Method 8260D: The laboratory control sample duplicate (LCSD) for analytical batch 180-432752 recovered outside control limits for the following analytes: Dichloro-difluoromethane. These analytes were biased high in the LCSD and were not detected in the associated samples; therefore, the data have been reported. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC/MS Semi VOA Method 8270E: The continuing calibration verification (CCV) associated with batch 180-432356 recovered above the upper control limit for Pentachlorophenol. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The associated sample is impacted: (CCVIS 180-432356/3).

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 2.4°C GC/MS VOA Method 8260D: MS & MSD was not spike and was out of tune. Minimal QC requirements were reached with LCS.(LCS 180-432587/4) Method 8260D: The continuing calibration verification (CCV) analyzed in 180-432587 was outside the method criteria for the following analyte(s): Dichloro-difluoromethane and Methyl acetate (HIGH). As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. Method 8260D: The laboratory control sample (LCS) for analytical batch 180-432587 recovered outside control limits for the following analytes: 1,1,2-Trichloro-1,2,2-trifluoroethane, Carbon disulfide, Dichloro-difluoromethane and Methyl acetate. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-432587 was outside the method criteria for the following analyte(s): Bromomethane, Chloroethane, Chloromethane, Trichlorofluoromethane and Vinyl chloride (LOW). A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC/MS Semi VOA Method 8270E: The continuing calibration verification (CCV) associated with batch 180-432297 recovered outside acceptance criteria, low biased, for Di-n-octyl phthalate. A reporting limit (RL) standard was analyzed, and the target analytes are detected. Since the associated samples were non-detect for the analyte(s), the data are reported. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC VOA No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. Hydrocarbons Method MAVPH: The following sample(s) were received in pre-weighed containers with a label that was added in the field, which would cause a slight low bias in the final results. EB-4 (8-10) (180-154822-1), EB-5 (8-10) (180-154822-2), EB-6 (8-10) (180-154822-3) and EB-7 (3-5) (180-154822-4). No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC Semi VOA Method MAEPH2.1: 1-Chlorooctadecane (Surr) recovery was outside acceptance limits for the following matrix spike/matrix spike duplicate (MS/MSD) sample: (180-154822-B-1-D MSD). The parent sample's surrogate recovery was within limits and the spike recovery of the MSD is within limits. The MS/MSD sample has been qualified and reported. Method MAEPH2.1: The breakthrough for naphthalene and 2-methylnaphthalene in the LCS and LCSD is <1%. The method requirement for breakthrough is <5%. EB-4 (8-10) (180-154822-1), EB-5 (8-10) (180-154822-2), EB-6 (8-10) (180-154822-3), EB-7 (3-5) (180-154822-4), (180-154822-B-1-C MS) and (180-154822-B-1-D MSD) Method MAEPH2.1: 1-Chlorooctadecane (Surr) recovery for the following samples were outside acceptance limits: EB-4 (8-10) (180-154822-1) and EB-6 (8-10) (180-154822-3). The samples cannot be re-extracted and re-analyzed within method holding time.

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 4.6°C GC/MS VOA Method 8260D_LL: The laboratory control sample (LCS) for analytical batch 180-433155 recovered outside control limits for the following analytes: 1,3-Dichlorobenzene and Chlorobenzene. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260D_LL: The following sample was diluted to bring the concentration of target analytes within the calibration range: TMW-1 (180-155027-3). Elevated reporting limits (RLs) are provided. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC/MS Semi VOA Method 625.1_LL_PREC: Received limited quantity, insufficient amount for MSD.(180-155027-C-2 MS) Method 625.1_LL_PREC: The matrix spike (MS) recoveries for preparation batch 180-432661 and analytical batch 180-432988 were outside control limits. Sample matrix interference is suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC VOA No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. Hydrocarbons No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC Semi VOA Method MAEPH2.1: The breakthrough for naphthalene and 2-methylnaphthalene in the LCS is <1%. The breakthrough for naphthalene and 2-methylnaphthalene in the LCSD is 1%. The method requirement for breakthrough is <5%. TMW-1 (180-155027-1), TMW-2 (180-155027-5) and TMW-3 (180-155027-12) Method MAEPH2.1: 1-Chlorooctadecane (Surr) recovery for the following samples were outside acceptance limits: TMW-1 (180-155027-1) and TMW-3 (180-155027-12). The samples cannot be re-extracted and re-analyzed within method holding time. The results have been reported per client request.
