The Site is approximately 1.04 acres in area and contains an approximately 8,750 ft2 commercial warehouse that is split into two separate tenant suites. ACTF reportedly operated out of Suite B from approximately 2015 to 2020. ACTF operations included servicing and maintenance of firetrucks and other related first responder vehicles. In March 2022, Highland Environmental Solutions, Inc. (HES) was contracted by the property owner to conduct assessment in areas of apparent staining observed on the interior concrete slab and exterior gravel area of the ACTF facility. In response, ACTF contracted with Civil & Environmental Consultants, Inc. (CEC) to confirm the results of HES’s assessment. HES’s and CEC’s assessment generally included the collection of soil samples from multiple interior and exterior locations in areas of apparent staining. Following CEC’s assessment, a second “supplemental” assessment was conducted by HES at the request of the property owner. The supplemental assessment activities conducted by HES included the removal of an approximate 1 ft by 1ft section of interior concrete slab, inspection and laboratory testing of the vapor barrier below the removed portion of the slab, and the collection of soil samples from below the vapor barrier. In summary, results of HES’s and CEC’s assessment activities indicated the presence of total petroleum hydrocarbons diesel range organics (TPH-DRO) above the North Carolina Department of Environmental Quality (NCDEQ) UST Action Level of 100 mg/kg in two (2) sample locations ranging from 299.7 mg/kg to 1,300 mg/kg. Based on the presence of TPH-DRO above action levels, the North Carolina Department of Environmental Quality (DEQ) requested that ACTF conduct a Limited Site Assessment (LSA) in a letter dated January 30, 2023. 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc At the request of ACTF, H&H conducted a Phase I LSA at the Site in April 2023. The Phase I LSA included the installation of one combination soil boring/temporary monitoring well in previous sample location S-7/CEC-A1/CEC-A2 which indicated the highest concentration of TPH-DRO detected during HES's and CEC’s prior assessments. Land Use/Risk Characterization As part of the LSA activities, H&H performed a site land use and risk characterization survey. The land use/risk classification survey included a water-supply well receptor survey within a 1,500 ft radius of the Site. H&H identified one potential WSW located approximately 1,300 ft topographically upgradient/cross gradient to the Site. No other WSWs were identified and remaining properties appear to have municipal water connections. According to the United States Geological Survey (USGS) topographic map dated 2022, no surface water bodies are located within 500 feet of the source area. The zoning of the site is Planned Development (PD). The properties in the surrounding area are primarily zoned as PD, Highway Commercial (HC), Residential (R-20), and Residential (R-40). The nearest residentially zoned property is located approximately 500 ft north-northwest and topographically upgradient of the source area. Phase I LSA Sampling On April 12, 2022, H&H oversaw the advancement of LSA soil boring HHSB-1, which was subsequently converted into temporary monitoring well HHTMW-1. LSA boring HHSB- 1/HHTMW-1 was installed in the approximate location of prior soil borings S-7 and CEC- A1/A2. In accordance with LSA guidelines, soil samples were collected from HHSB-1 in approximate 10 ft intervals until groundwater was encountered. Laboratory analytical results of the soil samples indicated the presence of C9-C22 aromatics (97.0 mg/kg) above the Soil-to-Groundwater Maximum Soil Contamination Concentration (MSCC) of 31 mg/kg at a depth of 0 ft to 2 ft below ground surface (bgs) in HHSB-1. Concentrations of C9-C22 aromatics were not detected in soil above the MSCC in the deeper samples collected (8 ft to 10 ft bgs, 18 ft to 20 ft bgs, and 28 to 30 ft bgs). Concentrations were 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc not detected in the soil samples collected from HHSB-1 above Residential or Industrial/Commercial MSCCs. Laboratory analytical results of the groundwater sample collected from HHTMW-1 did not indicate the presence of compounds above North Carolina Administrative Code 2L Standards (2L Standards) or Gross Contamination Levels (GCLs). Recommendations Based upon the results of the LSA, H&H recommends that DEQ issue a no further action (NFA) letter for this release incident. 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc 2.0 Introduction and Site History This Phase I LSA report documents assessment activities related to a non-UST petroleum release at the former ACFT facility located at 4718 Mountain Creek Avenue Suite B in Denver, Catawba County, North Carolina. The Site consists of one parcel (Parcel ID No. 368312962366) which is approximately 1.04 acres in area and contains an approximately 8,750 ft2 commercial warehouse. The Site was reportedly undeveloped land until the construction of the current commercial warehouse in approximately 2007. A Site location map is presented as Figure 1, and the Site map is depicted on Figure 2. ACFT operated in the eastern portion of the on-Site building in Suite B, from 2015 to 2020, performing fire truck maintenance activities. Highland Environmental Solutions, Inc. (HES) conducted an initial visual inspection of the former ACFT leased space on October 5, 2021. The initial inspection by HES identified staining on the interior concrete slab of the ACTF tenant space and in an exterior gravel area on the south side of the building. Following the inspection, soil assessment activities were conducted by HES on March 6, 2022. The soil assessment activities included the collection of eight (8) soil samples in interior and exterior areas of staining. Locations of HES’s soil samples are provided in Appendix D. Laboratory analytical results of the soil samples collected by HES indicated the presence of total petroleum hydrocarbons diesel-range organics (TPH-DRO) in sample SB-7 (202.5 mg/kg) above North Carolina Department of Environmental Quality (NCDEQ) Action Level of 100 mg/kg. A summary of the analytical results of HES’s soil assessment is provided in Appendix D. Following HES’s assessment, Civil & Environmental Consultants, Inc. (CEC) was retained by ACFT’s legal counsel to conduct further soil assessment at the Site. CECs assessment activities were conducted on June 29, 2022 and included the collection of twelve (12) soil samples from eleven (11) soil borings. The locations of CEC’s soil samples are provided in Appendix D. 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc Laboratory analytical results of the soil samples collected by CEC indicated the presence of TPH-DRO in samples CEC-A1 (150 mg/kg) and CEC-A2 (1,300 mg/kg) above the NCDEQ Action Level of 100 mg/kg. Samples CEC-A1 and CEC-A2 were collected from the same location as HES’s soil sample SB-7. A summary of the analytical results of CEC’s soil assessment is provided in Appendix D. Following CEC’s assessment, a second “supplemental” assessment was conducted by HES at the request of the property owner in September 2022. The supplemental assessment activities conducted by HES included the removal of an approximate 1 ft by 1ft section of interior concrete slab, inspection and laboratory testing of the vapor barrier below the removed portion of the slab, and the collection of a soil samples from below the vapor barrier. The location of the additional samples collected by HES during the supplemental assessment is provided Appendix D. Laboratory analytical results of the soil samples collected by HES indicated the presence of TPH-DRO in sample SL-1 (299.7 mg/kg) above the NCDEQ Action Level of 100 mg/kg. A summary of the analytical results of HES’s additional soil assessment is provided in Appendix D. Based upon the presence of TPH-DRO above NCDEQ Action Levels, DEQ requested that ACTF conduct a Phase I LSA at the Site. H&H performed the Phase I LSA in April 2023. The methods and results of the Phase I LSA are provided in the following sections. 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.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 1,500-ft radius of the former UST basin. 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. Based on the water supply well survey, municipal water is available to all properties but one within a 1,500-ft radius of the site. One water supply well was identified approximately 1,300 ft from the source area (Figure 4). The water supply well is cross to upgradient of the Site. Further, results of the Phase I LSA did not indicate the presence of groundwater impacts. As such, potential impacts to the identified water-supply well from the Site is not a concern. 3.1.2 Surface Water H&H conducted a visual survey for surface water bodies in the area during the receptor survey. According to the USGS topographic map, no surface water bodies are located within 500 feet of the source area. The closest surface water body is an unnamed tributary of Mundy Creek located approximately 510 ft south-southeast of the source area (Figure 1). Mundy Creek is located greater than 1,500 ft southeast of the source area. 7 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc 3.1.3 Subsurface Structures Visual observations were made for potential subsurface contamination conduits in the immediate vicinity of the HHBS-1/HHTMW-1 location. Based upon our review, there are no anticipated subsurface contamination conduits of concern in the area. 3.1.4 Property Owners and Land Use The site is currently developed and is not anticipated to be redeveloped in the near future. Surrounding properties are used primarily for commercial and residential purposes. The zoning of the site is Planned Development (PD). The properties in the surrounding area are primarily zoned as PD, Highway Commercial (HC), Residential (R-20), and Residential (R-40). The nearest residentially zoned property is located approximately 500 ft north-northwest and upgradient of the source area. 3.1.5 Wellhead Protection Areas Based on our review of the DEQ Wellhead Protection Program’s (WHPP) SWAP Info 2.0 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 an industrial/commercial land use classification. 8 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc 4.0 Geology and Hydrogeology 4.1 Regional Geology and Hydrogeology The subject property is located in the Piedmont Physiographic Province of North Carolina. According to the Geologic Map of North Carolina dated 1985, the subject property lies within the Late Paleozoic Intrusives terrane. In the site area, underlying bedrock is predominantly composed of granites and granodiorites. 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 shallow soil in the source area consists predominately of red to brown clayey silts with some sand to approximately 30 ft bgs. DPT refusal was encountered at approximately 30 ft bgs. As such, logging of subsurface lithology was not possible beyond 30 ft bgs. Based on topography, H&H expects that the groundwater flow direction is to the south or southeast. Bedrock was not encountered during the drilling actiivtes. 9 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc 5.0 Soil and Groundwater Sampling 5.1 Soil and Groundwater Assessment Activities On April 12, 2023, H&H oversaw the advancement of LSA soil boring HHSB-1, which was converted to temporary monitoring well HHTMW-1 in the approximate location of prior sample S-7 and CEC-A1/CEC-A2. The location of boring HH-SB-1/HHTMW-1 is shown on Figure 3. Soil and groundwater samples were collected in accordance with NCDEQ UST Section guidelines. Prior to drilling activities, H&H contacted North Carolina 811, the public utility locator, to mark subsurface utilities at the Site. In addition, H&H also contracted with Sweetwater Utility Exploration, LLC., a private utility locator, to screen the drilling location for subgrade utilities not marked by the public utility locator. In addition, prior to boring advancement, a decontaminated stainless-steel hand auger was used to clear the boring to a depth of approximately 5 ft below ground surface (bgs) to further screen the location for the presence of subsurface utilities. H&H contracted with Innovative Environmental Technologies, Inc. (IET) of Concord, North Carolina to install one co-located soil boring and temporary monitoring well. The soil boring log and temporary monitoring well construction details are provided in Appendix B. IET utilized an AMS Power Probe 9510 drill rig to advance HHSB-1 using direct-push technology (DPT) methods to refusal. During boring advancement, continuous soil samples were recovered in 5 ft Macro-Core acetate liners, logged for lithological description, and evaluated for evidence of impacts by visual observations, presence of odors, staining, and organic vapors as measured using a photo-ionization detector (PID). Based on the depth to water and in accordance with NCDEQ UST Section guidelines, soil samples were collected every 10 ft until groundwater is encountered. The soil samples from the uppermost and lowermost intervals (0 ft to 2 ft and 28 ft to 30 ft bgs, respectively) were analyzed for volatile organic compounds (VOCs) by EPA Method 8260B, semi-VOCs by EPA Method 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc 8270D, and volatile petroleum hydrocarbons (VPH) and Extractable Petroleum Hydrocarbons (EPH) by the Massachusetts Department of Environmental Protection (MADEP) Methods. Middle intervals (8 ft to 10 ft bgs and 18 ft to 20 ft bgs) were analyzed for VPH and EPH by the MADEP Methods in accordance with NCDEQ UST section guidance. The soil samples were submitted to Pace Analytical, a North Carolina-certified laboratory. Dedicated laboratory- supplied sample kits and jars were used for sample collection and 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 report are provided in Appendix C. A summary of the soil analytical results is provided on Table 1. Following collection of the soil samples, IET utilized air rotary and hollow stem auger drilling methods to advance the boring into the water table and construct temporary monitoring well HHTMW-1. The temporary monitoring well was installed to a total depth of 43 ft bgs and constructed using 2-inch diameter PVC riser with a 10 ft section of 0.010-inch slotted, pre- packed, PVC screen set to bracket the surficial aquifer. A filter sand pack was then installed from the bottom of the well boring to approximately two ft above the well screen, and an approximate 2 ft bentonite seal was installed above the filter sand pack. A summary of the temporary monitoring well construction details is provided on Table 2. Prior to sampling, H&H developed the temporary monitoring well in accordance with standard protocols. Following development, a groundwater sample was collected using a bladder pump and “low flow” sampling methods. During sampling, the temporary well was purged until field parameters of temperature, pH, specific conductivity, and oxidation reduction potential (ORP) stabilized. Following stabilization of field parameters, groundwater samples were collected and submitted for laboratory analysis of VOCs by EPA Method 6200, Bases Neutrals and Acids by EPA Method 625 plus the 10 highest tentatively identified compounds (TICs), Lead and Chromium by EPA Method 6020, and VPH and EPH by the MADEP Methods. 11 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc The groundwater samples were submitted to Pace Analytical, a North Carolina-certified laboratory. Dedicated laboratory-supplied sample kits and bottles were used for sample collection and 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 C. A summary of the groundwater analytical results is provided in Table 3 and Table 4. Following the collection of the groundwater sample, the temporary monitoring well was abandoned in accordance with North Carolina requirements. The abandonment record is provided in Appendix B. 5.2 Soil and Groundwater Analytical Results Laboratory analytical results of the soil samples indicated the presence of C9-C22 aromatics (97.0 mg/kg) in HHSB-1 at the depth interval of 0 ft to 2 ft bgs above the Soil-to-Groundwater MSCC of 31 mg/kg, respectively. In addition, a low-level concentration of methylene chloride was detected in HHSB-1 at the depth interval of 0 ft to 2 ft bgs and 28 ft to 30 ft bgs above the Soil-to Groundwater MSCC of 0.023 mg/kg. However, the detection of methylene chloride is flagged as a laboratory contaminant (C9) by the laboratory. In addition, methylene chloride was not detected in the previous sample collected by CEC at this location. As such, the methylene chloride concentration is not considered to be representative of Site conditions and is a result of laboratory contamination. No other compounds were detected above Soil-to-Groundwater MSCCs and concentrations were not detected above Residential or Industrial/Commercial MSCCs. Laboratory analytical results of the groundwater sample did not indicate the presence of VPH, EPH, VOCs, or SVOCs above laboratory reporting limits. Chromium and lead concentrations 12 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc were detected, but the reported concentrations are well below their respective 2L standards and are likely attributable to background concentrations. 13 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Atlantic Coast Fire Trucks (ACF)/Report/96932_PhaseILSA.doc 6.0 Summary and Recommendations Based on the Phase I LSA, the site qualifies for a low risk industrial/commercial classification. Results of Phase I LSA soil sampling indicate that compound concentrations are not present in soil above Residential or Industrial MSCCs. A concentration of C9 – C22 aromatics is present in shallow soil (0 ft to 2 ft bs), but deeper soil samples indicate that the concentrations C9 – C22 aromatics attenuate rapidly and do not pose a risk to groundwater. Further, results of the groundwater sampling do not indicate the presence of compounds in groundwater at the Site above the 2L Standards or GCLs. Because compounds concentrations detected in soil do not exceed Residential/Commercial MSCCs and the results of the soil and groundwater sampling do not indicate the potential for groundwater impacts from this release, H&H requests that DEQ issue a NFA letter for the incident.

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, no surface water bodies are located within 500 feet of the source area. The closest surface water body is an unnamed tributary of Mundy Creek located approximately 510 ft south-southeast 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? 3 The property is currently developed with one warehouse used for business/commercial operations. Prior to the existing structure having been built the property was undeveloped. 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 rear of the property currently is restricted with a locked chain link fence.. 6. Do pavement, buildings, or other structures cap the contaminated soil? The area of the UST release is currently partially capped with asphalt and/or concrete and is anticipated to be capped with asphalt and/or concrete during site redevelopment. 7. What is the zoning status of the property? The property is zoned as Planned Development (PD). 8. Is the use of the property likely to change in the next 20 years? The use of the site property is not likely to 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 residentially zoned parcel is approximately 500 ft north-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? Kids in Motion daycare is located approximately 1,250 ft west-southwest of the source area. 11. What is the zoning status of properties in the surrounding area? 4 The properties in the surrounding area are primarily zoned as PD, Highway Commercial (HC), Residential (R-20), and Residential (R-40). 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 and residential.
