A Site location map is included as Figure 1. The Phase I LSA was performed in response to a Notice of Regulatory Requirements issued by the North Carolina Department of Environmental Quality (DEQ) Underground Storage Tank (UST) Section dated November 22, 2022. The Site consists of one parcel of two contiguous parcels of land (Parcel ID Nos. 373110453053 and 37311045632) that total approximately 8.1 acres. The Site is developed with an approximately 11,600-square foot (sq ft) industrial office/service garage building that was constructed in 1962 and a roughly 4,800-sq ft storage/garage building that was constructed in the early to mid-1960s. The Site is occupied by New South Tractor, a farm, construction, and lawn equipment dealer. The remainder of the site consists of paved parking areas and driveways, concrete loading and storage areas, gravel storage areas, and undeveloped land. A Site map is provided as Figure 2. On September 15, 2022, H&H performed Phase II Environmental Site Assessment (ESA) soil and groundwater sampling activities at the Site to evaluate the potential for impacts from the north-south oriented trench drain in the central portion of the service department. Soil analytical data indicated the volatile organic compounds (VOCs) p-isopropyltoluene, naphthalene, and/or tetrachloroethylene (PCE) and the polycyclic aromatic hydrocarbons (PAHs) 1- methylnaphthalene, 2-methylnaphthalene, and/or naphthalene were detected above the Soil-to- Groundwater Maximum Soil Contaminant Concentrations (MSCCs) in soil samples SB-3 and SB-4. No detections exceeded the Industrial/Commercial MSCCs. Methylene chloride was also detected at low concentrations that appear to be related to laboratory contamination. 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc Groundwater analytical data did not indicate the presence of VOCs or PAHs at concentrations that are below the North Carolina 2L Groundwater Standards (2L Standards). Phase II ESA soil analytical data are summarized in Table 1, and groundwater analytical data are summarized in Table 2. Based on the Phase II ESA soil and groundwater data, it appears that a waste oil release has occurred from the closed trench drain in the central portion of the service garage. Land Use/Risk Characterization As part of the LSA activities, H&H performed a site land use and risk characterization survey. Municipal water is available to all properties within 1,000 ft of the source area. Water supply wells were not identified within 1,000 ft of the source area. Two unnamed tributaries of Cline Creek transect the southern portion of the Site. The Site is currently zone Highway Business District (B-2) and general manufacturing district (M-1). The properties in the surrounding area are primarily zoned business (B-2 and B-4), manufacturing (M-1), and residential (R-20A). The nearest residence is located approximately 350 ft northwest of the source area. Phase I LSA Sampling On March 6, 2023, H&H oversaw the advancement of one LSA soil boring/temporary monitoring well (SB-3A/TMW-2A) placed adjacent to the location of former soil boring/temporary well SB-3/TMW-2. Samples SB-3 and TMW-2 showed the highest level of impacts in soil during the Phase II ESA in September 2022. Soil analytical results for sample SB-3A (0-2) indicate the presence of several petroleum-related VOCs, semi-VOCs (SVOCs), C9-C18 aliphatics, and C9-C22 aromatics at concentrations above the Soil-to-Groundwater MSCCs. The detection of total C9-C22 aromatics also exceeds the Residential MSCC but is below the industrial/commercial MSCC. Total chromium and lead were detected in sample SB-3A (0-2) and SB-3A (21-23) at concentrations that are consistent with published background levels for North Carolina soil. 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc Groundwater analytical results for sample TMW-2A did not indicate the presence of VOCs, SVOCs, extractable petroleum hydrocarbons (EPH), volatile petroleum hydrocarbons (VPH), lead, or chromium at concentrations above the 2L Standards or the Gross Contamination Levels (GCLs). Recommendations Based upon the results of the Phase I LSA, H&H recommends that DEQ issue a risk-based No Further Action (NFA) letter for the release incident. As part of the NFA, H&H will complete public notice requirements and file a Notice of Residual Petroleum (NORP) based on the presence of C9-C22 aromatics above the Residential MSCC. Based on the isolated nature of soil contamination, H&H requests that an alternate NORP restricting disturbance of impacted soil be approved to allow for future residential use of the Site. A map showing the estimated extent of soil contamination will be attached to the NORP. 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc 2.0 Introduction and Site History This Phase I LSA report documents assessment activities at 977 and 985 US Highway 70 in Newton, North Carolina. A Site location map is included as Figure 1. The Phase I LSA was performed in response to a Notice of Regulatory Requirements issued by the DEQ UST Section dated November 22, 2022. The Site consists of one parcel of two contiguous parcels of land (Parcel ID Nos. 373110453053 and 37311045632) that total approximately 8.1 acres. The Site is developed with an approximately 11,600-sq ft industrial office/service garage building that was constructed in 1962 and a roughly 4,800-sq ft storage/garage building that were constructed in the early to mid- 1960s. The Site is occupied by New South Tractor, a farm, construction, and lawn equipment dealer. The remainder of the site consists of paved parking areas and driveways, concrete loading and storage areas, gravel storage areas, and undeveloped land. A Site map is provided as Figure 2. On September 15, 2022, H&H performed Phase II ESA soil and groundwater sampling activities at the Site to evaluate the potential for impacts from equipment service operations and an associated trench drain and wastewater discharge to a drainage ditch. A summary of the assessment results is provided below.  No obvious evidence of current or former USTs was identified during a ground- penetrating radar (GPR) survey. The GPR survey also indicated that a closed trench drain in the equipment service garage previously discharged waste fluids to a drainage ditch in the western portion of the Site.  Three soil samples were collected to evaluate potential soil impacts along the closed trench drain in the equipment service garage, and one soil sample was collected near the former location of wastewater discharge to the drainage ditch. Two groundwater samples were collected to evaluate potential groundwater impacts from equipment services activities and former waste fluid collection in the trench drain. 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc  Field evidence of petroleum-related soil impacts was identified along the trench drain during field screening.    Laboratory analytical results indicate the presence of p-isopropyltoluene, PCE, naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene in one or more soil samples collected adjacent to the trench drain at concentrations above the Soil-to-Water MSCCs. The detected concentrations of these compounds do not exceed the Residential or Industrial/Commercial MSCCs.    Methylene chloride was also detected in samples SB-2 through SB-4; however, methylene chloride is a common laboratory contaminant, particularly at the low concentrations detected in soil samples collected at the Site. As such, the methylene chloride detections are not likely representative of soil conditions at the Site.    Results of the hypothetical worst-case risk calculations using soil data indicate that cumulative carcinogenic and non-carcinogenic risks are below the DEQ and EPA acceptable levels for residential and non-residential worker exposure scenarios.  Groundwater analytical data do not indicate the presence of PAHs in groundwater at concentrations above the respective 2L Standards. No VOCs were detected above the laboratory method reporting limits in TMW-1 or TMW-2. Phase II ESA soil and groundwater analytical data are summarized in Tables 1 and 2, respectively. 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc 3.0 Receptor Information and Risk Characterization As part of the Phase I LSA, H&H performed a Site land use and risk characterization survey. The LSA Risk Classification and Land Use Form is provided in Appendix A. A discussion of potential receptors and land use is provided below. 3.1 Receptor Information 3.1.1 Water Supply Wells H&H conducted a water supply well survey for the area within a 1,000-ft radius of the source area. The survey was conducted by performing area reconnaissance and checking for municipal water connections. H&H also interviewed tenants and landowners of occupied properties within 500 ft of the source area regarding their water usage. As of the data of this report, two completed Water Supply Well Information Survey forms were received by H&H and are provided in Appendix B. Please note that based on information obtained during interviews with nearby property owners during the survey, the properties within 500 ft of the source area are connected to the municipal water supply and no water supply wells were identified. Based on the water supply well survey, municipal water is available to all properties within a 1,000-ft radius of the Site and no water supply wells were identified. 3.1.2 Surface Water H&H conducted a visual survey for surface water bodies in the area during the receptor survey. Two unnamed tributaries of Cline Creek transect the southern portion of the Site. The closest unnamed tributary of Cline Creek is located approximately 300 ft south of the source area (see Figure 2). 7 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc 3.1.3 Subsurface Structures Visual observations were made for potential subsurface contamination conduits in the immediate vicinity of the service garage building. Based upon our review, there are no anticipated subsurface contamination conduits of concern in the source area or nearby surrounding area. 3.1.4 Property Owners and Land Use The Site is currently occupied by New South Tractor, a farm, construction, and lawn equipment dealer. Surrounding properties are used primarily for commercial, manufacturing, and residential purposes. The Site is currently zoned Highway Business District (B-2) and General Manufacturing District (M-1). The properties in the surrounding area are primarily zoned business (B-2 and B-4), manufacturing (M-1), or residential (R-20A). The nearest residence is located approximately 350 ft northwest of the source area. Contiguous property owners are shown on Table 3 and cross-referenced on Figure 3. 3.1.5 Wellhead Protection Areas Based on our review of the DEQ Wellhead Protection Program’s (WHPP) SWAPInfo2.0 mapping database, the Site is not located in a wellhead protection area. 3.2 Risk and Land Use Characterization Based upon the receptor data, as well as the Phase I LSA groundwater analytical data presented in Section 5.0, the Site qualifies for a low-risk designation. In addition, based upon the zoning of the Site and surrounding area, the Site qualifies for a commercial/industrial land use classification. 8 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc 4.0 Geology and Hydrogeology 4.1 Regional Geology and Hydrogeology The Site is in the Piedmont Physiographic Province of North Carolina. According to the Geologic Map of North Carolina dated 1985, the subject property lies within the Inner Piedmont Belt. In the Site area, underlying bedrock is composed of amphibolite and biotitic gneiss. The land surface of the area is generally characterized as gently sloping, which may become moderately steep where intersected by streams. In the Piedmont, the bedrock is overlain by a mantle of weathered rock termed saprolite or residuum. The saprolite consists of unconsolidated clay, silt, and sand with lesser amounts of rock fragments. Due to the range of parent rock types and their variable susceptibility to weathering, the saprolite ranges widely in color, texture, and thickness. Generally, the saprolite is thickest near interstream divides and thins toward streambeds. In profile, the saprolite normally grades from clayey soils near the land surface to highly weathered rock above competent bedrock. The occurrence and movement of groundwater in the Piedmont is typically within two separate but interconnected water-bearing zones. A shallow water-bearing zone occurs within the saprolite, and a deeper water-bearing zone occurs within the underlying bedrock. 4.2 Site Hydrogeology Soil samples collected during the Phase I LSA indicate that soils in the source area consist predominately of red, brown, and orange sandy clay and sandy silt to a depth of approximately 35 ft below ground surface (bgs). Groundwater was encountered at a depth of approximately 27 ft bgs in temporary monitoring well TMW-2A. Groundwater flow in the source area is expected to mimic topography and flow primarily to the south towards two unnamed tributaries of Cline Creek. 9 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc 5.0 Soil and Groundwater Sampling 5.1 Soil and Groundwater Sampling Methodology On March 6, 2023, H&H oversaw the advancement of LSA soil/boring temporary monitoring well SB-3A/TMW-2A in the approximate former location of Phase II ESA boring/temporary monitoring well SB-3/TMW-2 (see Figure 2). Ameriprobe, LLC of Huntersville, North Carolina utilized a Geoprobe 7720 DT drill rig to advance SB-3A/TMW-2A to approximately 35 ft bgs using direct push drilling methods. During boring advancement, soil was recovered in 5 ft macrocore liners and evaluated for evidence of impacts by visual observations, presence of odors, staining, and organic vapors as measured using a calibrated photoionization detector (PID). A boring log including PID readings is included in Appendix C. DEQ UST Section guidelines indicate a soil sample should be collected every 5 ft when the water table is less than 25 ft bgs. Although the depth to water of was measured at 26.72 ft bgs, H&H conservatively collected four soil samples from boring SB-3A for laboratory analysis at depth intervals of approximately 0-2 ft bgs, 7-9 ft bgs, 14-16 ft bgs, and 21-23 ft bgs. The soil samples collected from 0-2 ft bgs and 21-23 ft bgs were analyzed for VOCs by EPA Method 8260D, SVOCs by EPA Method 8270E, VPH and EPH by Massachusetts Department of Environmental Protection (MADEP) methods, and lead/chromium by EPA Method 6020B. The two intermediate depth soil samples were submitted for laboratory analysis of VPH and EPH by MADEP methods. Laboratory analyses were based on DEQ UST Section guidelines for a waste oil release. Temporary monitoring well TMW-2A was installed to a depth of approximately 35 ft bgs. The well was constructed of 1-inch diameter PVC casing with a 15 ft section of 0.010-inch slot pre- packed PVC screen that was set to bracket the water table. Filter sand was placed in the well annulus from the base of the borehole to approximately 2 ft above the well screen, and a hydrated bentonite seal was placed above the sand pack. On March 6, 2023, the depth to 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc groundwater was measured at approximately 26.72 ft bgs using decontaminated electronic water level indicator. A temporary well diagram is shown on the boring log provided in Appendix C. Prior to groundwater sampling, H&H developed the temporary monitoring well using a peristaltic pump and dedicated polyethylene tubing. The well was then purged using low-flow methods, and H&H collected field measurements of temperature, pH, specific conductivity, and oxidation reduction potential (ORP) during the purging process. A low-flow groundwater sampling form is provided in Appendix D. The groundwater sample from TMW-2A was submitted for laboratory analysis of VOCs by Standard Method 6200B, SVOCs plus the 10 highest tentatively identified compounds (TICs) by EPA Method 625, VPH and EPH by the MADEP Methods, and lead and chromium by EPA Method 6020B. The soil and groundwater samples were submitted to Pace Analytical, a North Carolina-certified laboratory. Dedicated laboratory-supplied sample kits and bottles were used for sample collection. The samples were placed in an iced cooler after collection. A chain-of-custody record was completed for the samples collected and included the sample description, date collected, time collected, matrix, sample container information, and analyses required. The chain-of-custody was signed by field personnel prior to placement in the iced sample cooler for shipment to the laboratory. The chain-of-custody record and laboratory analytical data sheets are provided in Appendix E. 5.2 Soil Sampling Results Soil analytical results for sample SB-3A (0-2) indicate the presence of several petroleum-related VOCs, PAHs, C9-C18 aliphatics, and C9-C22 aromatics at concentrations above the Soil-to- Groundwater MSCCs. The detection of total C9-C22 aromatics (820 mg/kg) also exceeds the Residential MSCC of 469 mg/kg. Total chromium (75.5 mg/kg) and lead (12.7 mg/kg) were detected at concentrations that are within the published ranges of background concentrations for North Carolina soil of 7.0 to 300 mg/kg and non-detect to 50 mg/kg, respectively. Neither EPH 11 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/New South Tractor/LSA/Report/Phase I LSA - New South Tractor (3-31-23).doc nor VPH were detected above the laboratory method detection limits in the two intermediate depth soil samples SB-3A (7-9) and SB-3A (14-16). Soil analytical results for the deeper sample SB-3A (21-23) do not indicate the presence of VOCs, SVOCs, EPH, or VPH at concentrations above the laboratory method detection limits. Lead and chromium were detected in soil sample SB-3A (21-23) at concentrations consistent with published background levels for North Carolina soil. 5.3 Groundwater Sampling Results Groundwater analytical results for sample TMW-2A indicate the presence of several petroleum- related VOCs, naphthalene, lead, and total chromium in TMW-2A at concentrations below the 2L Standards and GCLs. No aliphatics or aromatics were detected at concentrations above laboratory detection limits. 5.4 Conclusion and Recommendations Based on the results of the receptor survey and LSA soil and groundwater sampling, the Site qualifies for a low-risk commercial/industrial classification. Based upon the results of the Phase I LSA, H&H recommends that DEQ issue a risk-based NFA letter for the release incident. As part of the NFA, H&H will complete public notice requirements and file a NORP based on the presence of C9-C22 aromatics above the Residential MSCC. Based on the isolated nature of soil contamination, H&H requests that an alternate NORP restricting disturbance of impacted soil be approved to allow for future residential use of the Site. A map showing the estimated extent of soil contamination will be attached to the NORP.

Has the discharge or release contaminated any water supply well including any used for non-drinking purposes? The discharge or release has not resulted in known contaminated water wells in the site area. 2. Is a water supply well used for drinking water located within 1,000 feet of the source area of the discharge or release? Water supply wells used for drinking water were not identified within 1,000 ft of the source area. 3. Is a water supply well used for any purpose (e.g., irrigation, washing cars, industrial cooling water, filling swimming pools) located within 250 feet of the source area of the release or discharge? Water supply wells used for any purpose were not identified within 250 ft of the source area. 4. Does groundwater within 500 feet of the source area of the discharge or release have the potential for future use in that there is no other source of water supply other than the groundwater? The subject site and surrounding properties are served by the municipal water supply. 5. Do vapors from the discharge or release pose a threat of explosion because of accumulation of the vapors in a confined space, or pose any other serious threat to public health, public safety or the environment? Vapors from the discharge or release do not pose a threat of explosion and do not pose a serious threat to public health, public safety, or the environment. 6. Are there any other factors that would cause the discharge or release to pose an imminent danger to public health, public safety, or the environment? No other factors would cause the discharge or release to pose an imminent danger to public health, public safety, or the environment. 2 Intermediate Risk 7. Is a surface water body located within 500 feet of the source area of the discharge or release? According to the USGS topographic map, an unnamed tributary of Cline Creek is located approximately 300 feet south of the source area. 8. Is the source area of the discharge or release located within a designated wellhead protection area as defined in 42 USC 300h-7(e)? The source area is not located within a designated wellhead protection area. 9. Is the discharge or release located in the Coastal Plain physiographic region as designated on a map entitled "Geology of North Carolina" published by the Department in 1985? If yes, is the source area of the discharge or release located in an area in which there is recharge to an unconfined or semi-confined deeper aquifer that is being used or may be used as a source of drinking water? The discharge or release is not located in the Coastal Plain physiographic region. 10. Do the levels of groundwater contamination for any contaminant exceed the gross contamination levels established (see Table 3) by the Department? Detected concentrations do not exceed Gross Contamination Levels. Part II - Land Use Property Containing Source Area of Discharge or Release 1. Does the property contain one or more primary or secondary residences (permanent or temporary)? The property does not contain a primary or secondary residence. 2. Does the property contain a school, daycare center, hospital, playground, park, recreation area, church, nursing home, or other place of public assembly? The property does not contain a place of public assembly. 3. Does the property contain a commercial (e.g., retail, warehouse, office/business space, etc.) or industrial (e.g., manufacturing, utilities, industrial research and development, chemical/petroleum bulk storage, etc.) enterprise, an inactive commercial or industrial enterprise, or is the land undeveloped? The property is currently developed with an approximately 11,600-square foot (sq ft) industrial office/service garage building that was constructed in 1962 and a roughly 3 4,800-sq ft storage/garage building that was constructed in the early to mid-1960s. The Site is occupied by New South Tractor, a farm, construction, and lawn equipment dealer. The remainder of the site consists of paved parking areas and driveways, concrete loading and storage areas, gravel storage areas, and undeveloped land. 4. Do children visit the property? Children currently do not visit the property. 5. Is access to the property reliably restricted consistent with its use (e.g., by fences, security personnel or both)? Access to the property is currently restricted by a fence. 6. Do pavement, buildings, or other structures cap the contaminated soil? The area of the trench drain release is capped with a concrete slab foundation.. 7. What is the zoning status of the property? The property is zoned Highway Business District (B-2) and General Manufacturing District (M-1). 8. Is the use of the property likely to change in the next 20 years? The use will not likely change in the next 20 years. Property Surrounding Source Area of Discharge or Release The questions below pertain to the area within 1500 feet of the source area of the discharge or release (excludes property containing source area of the release): 9. What is the distance from the source area of the release to the nearest primary or secondary residence (permanent or temporary)? The nearest residence is located approximately 350 ft northwest of the source area. 10. What is the distance from the source area of the release to the nearest school, daycare center, hospital, playground, park, recreation area, church, nursing home or other place of public assembly? Covenant Christian Church is located approximately 800 ft southeast of the source area. 4 11. What is the zoning status of properties in the surrounding area? The properties in the surrounding area are primarily zoned business (B-2, B-4), manufacturing (M-1), or residential (R-20A). 12. Briefly characterize the use and activities of the land in the surrounding area. The primary land use in the immediate vicinity of the site is commercial, residential, and light industrial.

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. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should be considered an estimated value.IK Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 The reported TIC has an 85% or higher match on a mass spectral library search.N The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request.N2 RPD value was outside control limits.R1 Surrogate recovery not evaluated against control limits due to sample dilution.S4 Surrogate recovery outside control limits due to matrix interferences (not confirmed by re-analysis).S5 The continuing calibration verification was above the method acceptance limit.
