The Site is an active gas station and convenience store. On November 6, 1997, a release from the Site’s gasoline underground storage tank (UST) system was reported. As a result, several environmental assessment activities have been performed on the Site and nearby locations. Currently, a Dual-Phase Extraction (DPE) system operates at the Site. The DPE system recovers, treats, and discharges petroleum impacted groundwater and soil vapor. The DPE system currently operates in 6-month intervals. According to the initial CAPR, submitted by Mid-Atlantic Associates, Inc. (MAA – Speedway’s former environmental consultant) on December 7, 2021 (MAA, 2021a), the first operating period occurred from March to September 2021. During that time, the DPE system had a total downtime of 33 days, resulting in a runtime efficiency of 82%. Five air stack samples and five treated liquid discharge samples were collected during this initial operating period. A total of 187,966 gallons (approximately 1,033 gallons per day) of groundwater were extracted, and an estimated 710 gallons of petroleum were removed as vapor during the first operating period. On October 4, 2021, groundwater sampling and gauging activities were performed, and a Groundwater Monitoring Report was submitted by MAA on December 7, 2021 (MAA, 2021b). The groundwater sampling results indicated that several Site monitoring wells exhibited constituent concentrations above the Title 15A NCAC 2L.0202 Groundwater Quality Standard (2L Standard), and monitoring wells MW-19 and MW-21 exhibited benzene concentrations exceeding the Gross Contaminant Level (GCL). Light non-aqueous phase liquid (LNAPL) was not detected in any monitoring wells during the October 4, 2021 sampling and gauging event. The activities conducted during the second DPE system operating period (March 2022 through September 2022) are summarized as follows: • AECOM personnel conducted groundwater gauging activities for 11 monitoring wells and groundwater sampling activities for eight monitoring wells. • DPE system operation and maintenance (O&M) was conducted on a routine and as-needed basis to maintain system operation. • Air stack samples and treated liquid discharge samples were collected from the DPE system on a routine basis. Based on the observations and results from the second DPE system operating period that are detailed in this report, AECOM concludes the following: • Several constituents of concern (CoCs) were detected in groundwater at concentrations exceeding the 2L Standards. • Benzene was detected in monitoring well MW-21 at a concentration exceeding the GCL. • Measurable LNAPL was present in monitoring well MW-19 at a thickness of 0.02 feet. • The DPE system operated with a runtime efficiency of 92 percent (%). • The DPE system recovered and treated 120,603 gallons of petroleum impacted groundwater at an average effective pump rate of 726.3 gallons-per-day (gpd). • Mass removal calculations estimated 320.39 gallons of petroleum were removed as vapor by the DPE system. • Mass removal efficiency of the DPE system appears to increase overtime through continuous operation. • The DPE system may be mobilizing contaminant mass towards the extraction wells from the surrounding formation. Based on these conclusions, AECOM, on behalf of Speedway, recommends the following: AECOM ES-2 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 • Continue operating the DPE system. Extend the operational period from six months to 12 months in order to further evaluate the increasing trends of mass removal efficiency over time. • Perform semi-annual groundwater sampling while the DPE system is operating in order to evaluate the effects of the system on localized groundwater elevations (e.g., radius of influence, groundwater drawdown, and cones of depression) and groundwater CoC concentrations. The first event should occur after six months of operation and the second event should occur after 12 months of operation. • Continue to perform monthly air stack sampling of the DPE system. • Continue to perform quarterly sampling of the DPE system treated liquid discharge. • Collect influent liquid samples during the quarterly discharge sampling in order to further evaluate and monitor mass removal as liquid and air stripper/active carbon treatment efficiency. • Generate and submit a CAPR after 12 months of operation summarizing the results and conclusions after implementation of the above recommendations. 1-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 1 Introduction As required by the NCDEQ, AECOM has prepared this CAPR, on behalf of Speedway, to document the second operating period of the DPE system as well as the activities and results of the November 8, 2022 groundwater monitoring event conducted at the Site. The Site is located at 653 East Webb Avenue, Burlington, North Carolina 27217 (Figure 1). The Site is an active gas station and convenience store. The layout of the facility, Site features, and surrounding properties are illustrated in Figure 2. Based on the previous remediation activities and historical assessment data, a New Technology Cleanup Plan (NTCP) (MAA, 2017) was approved by the NCDEQ to implement a full-scale DPE system at the Site. Construction of the system was initiated on September 17, 2020 and completed on March 8, 2021 when operation began. 2-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 2 Site Background Information The following sections provide site background and contact information. 2.1 Site Identification Date of Incident Report: November 6,1997 Incident Number: 19272 Facility ID: 0-004038 Site Rank: High (H180E) Site Name: Speedway 6958 Site Street Address: 653 East Webb Avenue City/Town: Burlington Zip Code: 27217 County: Alamance Latitude/Longitude: 36.08815 / -79.43034 2.2 Contact Information Property Owner: Speedway, LLC Address: 500 Speedway Dr., Enon, OH 45323 Telephone: (919) 268-7176 Property Occupant: Speedway, LLC Address: 500 Speedway Dr., Enon, OH 45323 Telephone: (919) 268-7176 UST Owner: Speedway, LLC Address: 500 Speedway Dr., Enon, OH 45323 Telephone: (919) 268-7176 UST Operator: Speedway, LLC Address: 500 Speedway Dr., Enon, OH 45323 Telephone: (919) 268-7176 Consultant/Contractor: AECOM Address: 5438 Wade Park Boulevard, Suite 200, Raleigh, NC 27607 Telephone: 919-461-1100 2.3 Release Information On November 6, 1997, a release from the gasoline UST system located at the Site was reported. As a result, a soil vapor extraction and vacuum-enhanced groundwater recovery and treatment (SVE/GW) system was installed in 2001. Shortly after installation, LNAPL and vapors were discovered in the Willowbrook Hosiery facility, located at 413 Tucker Street which is downgradient of the known extent of the release. An emergency vapor recovery (VR) system was installed to remove vapors from the Willowbrook Hosiery facility; however, the remediation system was permanently shut down in December 2004 under Session Law 2004-124. The former Site owner (WilcoHess) renovated the Site in 2005. The renovation consisted of removing and replacing the USTs, product lines, and dispensers, razing Site buildings, and constructing a new building. The renovation also involved abandoning former remediation and monitoring wells and removing the former soil vapor extraction/ vacuum- enhanced groundwater recovery and treatment system (SVE/GW). With the lowering of the Trust Fund “funding bar” in 2008, the NCDEQ directed the renewal of assessment and remediation activities at the Site. Based on Site subsurface characterization, the groundwater contaminant plume has migrated off-site, in the direction of the adjacent residential apartment complex, the Bateman residence, and the Willowbrook facility, where LNAPL and impacted groundwater have historically been observed in the basement. LNAPL has also been intermittently present in four off-site monitoring wells (MW-19, MW-21, MW-23, and MW-24), generally located west of the Site (Figure 2). Passive LNAPL recovery activities (such as absorbent socks) were conducted from February 2009 through December 2009, and a total of seven Mobile Multi-Phase Extraction (MMPE) events were completed at the 2-2 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 Site from June 2012 to January 2015. Selected historical Site assessment data was provided in the Groundwater Monitoring Report dated December 7, 2021 (MAA, 2021b). 3-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 3 Site History and Characterization The following sections provide information on the Site including USTs operated at the Site and follows the general outline established in Guidelines for Assessment and Corrective Action for UST Releases (NCDEQ, 2021a) and Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases (NCDEQ, 2021b). 3.1 Site Characteristics The Site is an active gas station and convenience store located at 653 East Webb Avenue, Burlington, North Carolina 27217 (Figure 1). The layout of the facility, Site features, and surrounding properties are illustrated in Figure 2. The Site is accessed from East Webb Avenue, east of the Site, and Tucker Street, south of the Site. Commercial and residential properties surround the Site. 3.2 Site Geology and Hydrogeology Site geology and hydrogeology were evaluated based on historical and current investigations. The Site is located within the Piedmont physiographic province. The subsurface generally consists of clayey silts and silty clays interlayered with medium to coarse sands and quartz lenses. The Site’s geologic profile consists of silty clay in the first four feet (ft) below land surface (bls) and then becomes tan-light brown clayey silt (saprolitic) to 15 ft bls. Extremely weathered rock was encountered from 15 to 20 ft bls (MAA, 2021a). Based on the previous borings advanced at the Site, the lithologic units beneath the Site appear to be laterally discontinuous (MAA, 2021a). Therefore, a preferential migration pathway (e.g., a former stream bed, fracture zone, dike, etc.) may exist between the Site and the Willowbrook Hosiery facility, allowing for accelerated transport of contaminants. Groundwater has historically been encountered at approximately 12 ft bls. Based on the results of the most recent gauging event (November 8, 2022), general groundwater flow is to the southwest, which is consistent with historical groundwater flow. 3.3 Underground Storage Tank Systems UST owner operator and other responsible party information is provided in Table 1. A summary of the USTs maintained at the Site is provided below and summarized in Table 2. Currently, there are four double-walled, steel USTs with fiberglass coating at the Site. There is one 15,000-gallon regular unleaded gasoline UST, one 8,000-gallon premium unleaded gasoline UST, one 12,000-gallon diesel UST, and one 10,000-gallon kerosene UST. 3.4 Aboveground Storage Tank Systems No aboveground storage tank (AST) systems are currently present on-site. Based on available information, no ASTs have historically been present at the Site. 3.5 Historical Releases Based on the NCDEQ Incident Management Database (NCDEQ, 2022a), there are two historical releases (UST incident number 19272 and UST incident number 48221). The UST incident number 19272 is the subject incident, reported on November 6, 1997. WilcoHess, LLC (WilcoHess) was the responsible party. The UST incident number 48221 was reported on January 20, 2022 when the under-dispenser containment of Dispenser 1/2 failed triennial hydrostatic testing. Repairs were made and a post-repair hydrostatic test passed. A Site Check Report (MAA, 2022) concluded that petroleum impacts (benzene and xylenes) were detected above NCDEQ action levels, however, any impact to groundwater would be commingled with the prior release associated with NCDEQ incident number 19272. NCDEQ has not responded to this report and the incident is currently open with no risk classification. Speedway was the responsible party. 3-2 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 3.6 Zoning According to the Burlington Zoning Viewer Map (City of Burlington, 2022), the properties surrounding the Site are zoned Residential, General Business, and Industrial. The Site is currently zoned as General Business, and the Site’s adjoining properties are zoned as General Business and Medium Density Residential. The main zones within 1,500 ft of the Site are Residential, Industrial, Office Institutional, and General Business. Currently, west of the Site are residential properties, beyond which is East Davis Street; to the north are Davis Street United Methodist Church and Alamance Funeral Service, beyond which is Cameron Street; to the east is East Webb Avenue, beyond which is Stillwood Ammunition Systems; to the south of the Site is Friendly Check Cashing, beyond which is DEKRA Emissions & Safety Station. A zoning map is provided as Figure 3. Adjacent property owners are identified in the table and drawing that are provided in Appendix A. 3.7 Receptor Information A receptor survey update was not conducted as part of this reporting period. Receptor information for the Site was documented in the Comprehensive Site Assessment (CSA) submitted by MAA on October 21, 1998 (MAA, 1998). 3.7.1 Public Water Supply Wells No water supply wells were identified within 1,500 ft of the Site (MAA, 1998). 3.7.2 Private Water Supply Wells Based on information obtained from the NCDEQ Division of Water Resources database (NCDEQ Division of Water Resources, 2021), the municipal water service covers the Site and surrounding area. Therefore, surrounding properties are expected to be connected to public water. According to the NC’s Source Water Assessment Program ([SWAP] NCDEQ, 2021c) 2.0 Geographic Information System (GIS) online mapping application, the nearest registered groundwater community well is approximately 6,200 ft northeast of the Site, located at the Stoney Creek Reservoir. 3.7.3 Public Water Systems The City of Burlington’s municipal water and sewer are available to the Site and properties surrounding the Site. The city obtains its water from Lake Macintosh and Stoney Creek Reservoir. 3.7.4 Surface Water According to the Ground Water Management Branch Map Interface (NCDEQ 2022b), the closest surface water bodies are the Dye Branch, located approximately 1,400 ft west of the Site, and an unnamed tributary of Haw River located about 1,000 ft east of the Site. The surface waters around the Site are illustrated in Figure 3. 3.7.5 Wellhead Protection Areas No wellhead protection areas were identified within 1,500 ft of the Site (NCDEQ, 2021c). 3.7.6 Subsurface Structures Currently, there are no known subsurface structures (basements, etc.) at the Site that could potentially accumulate fuel vapors. However, there are several subsurface structures that may have influenced the migration path of impacted groundwater. The subsurface structures are summarized below: • Underground utility lines have been identified in the vicinity of the former UST locations. Usually, utilities are buried two to four ft bls (MAA, 2021a). • Sanitary sewer pipes (and/or the trench in which they are situated) located beneath East Davis Street may have intersected the water table in the past. The elevation (relative to the Site benchmark) of the bottom of the sewer pipe is approximately 80 ft (MAA, 2021a). • LNAPL and impacted groundwater have historically been observed in the basement of the Willowbrook Hosiery building. • Previous vapor monitoring of the basement for the Bateman residence did not reveal evidence of petroleum vapors (MAA, 2021a). 3-3 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 3.8 Initial Abatement and Remediation Activities On November 6, 1997, a release of regular unleaded gasoline was discovered from an impact valve air pressure gauge on an underground line feeding a dispenser island located at the Site’s north end. The volume of the release is unknown. The leak was repaired, and subsequent assessments revealed the presence of LNAPL on the water table. A CSA was conducted at the Site, as well as LNAPL recovery. Thirty Aggressive Fluid/Vapor Recovery (AFVR) events were conducted, which removed approximately 1,525 gallons of LNAPL from the water table. The North Carolina Department of Environment Natural Resources (NCDENR), Division of Waste Management (DWM) classified the Site as “intermediate” based on the presence of petroleum-fuel-related compounds in groundwater at concentrations exceeding the GCLs. The September 6, 2000 Corrective Action Plan ([CAP] MAA, 2000) suggested the implementation of the SVE/GW system. The SVE/GW system was installed in 2001, but shortly after installation, LNAPL and vapors were discovered in the Willowbrook Hosiery building, located at 423 Tucket Street, which is downgradient of the known extent of the release. An emergency VR system consisting of vertical wells placed along the Willowbrook Hosiery building’s foundation and connected to a blower was installed and successfully removed vapors from the building. The SVE/GW system was permanently shut down on November 30, 2004 due to Session Law 2004-124; however, the VR system at the Willowbrook Hosiery property continued to operate. WilcoHess renovated the Site in 2005. The renovation consisted of removing and replacing the USTs, product line, and dispensers, razing Site buildings, and constructing a new building. The renovation also involved abandoning former remediation and monitoring wells and removing the former remediation system. With the lowering of the Trust Fund “funding bar” in 2008, the NCDEQ directed the renewal of assessment and remediation activities at the Site. During assessment activities, LNAPL was not found at the Site, but three off-site monitoring wells (MW-21, MW-23, and MW-24) exhibited LNAPL. The monitoring wells are located on the adjacent and surrounding properties northwest of the Site (Figure 2). After LNAPL was detected in the monitoring wells, passive skimming devices (such as absorbent socks) were installed to recover the LNAPL. Manual LNAPL recovery activities were then conducted from February 2009 through December 2009. The Free Product Recovery Report dated January 25, 2010 (MAA, 2010) documented the results of the LNAPL recovery activities and recommended the evaluation of more aggressive active LNAPL recovery methods. Based on the evaluation, three subsequent MMPE events were conducted at the Site from June 2012 to August 2013. Based on historical LNAPL recovery results and discussions between MAA and NCDEQ, it was determined that additional MMPE events would be conducted at the Site on a quarterly basis. Four additional MMPE events were conducted at the Site from April 2014 to January 2015. While performing the additional MMPE events, the VR system at the Willowbrook Hosiery building and the absorbent socks were inspected twice a month. The additional MMPE events recovered approximately 21,791 gallons of product/water mix, with an estimated 277 gallons of gasoline removed as vapor. LNAPL was not detected in any of the monitoring wells over the reporting period (MAA, 2021b). Based on the MMPE events’ effectiveness and a historical assessment data review, a NTCP was approved by NCDEQ to implement a full-scale DPE system at the Site. Construction of the system was initiated on September 17, 2020. The construction involved the installation of six extraction wells (DPE-01 through DPE-06), followed by trenching, conduit placement, installation of well boxes at each extraction well, pouring of a concrete pad for the DPE system enclosure, completion of a manifold connection point adjacent to the concrete pad, and a connection to the City of Burlington sanitary sewer. On February 17, 2021, a DPE treatment system enclosed in a mobile trailer unit (MTU) was transported to the Site and placed on the concrete pad. An electric meter was installed, and the electric line was energized by Duke Power the week of March 8, 2021. Well construction details for all wells installed at the Site are summarized in Table 3. Locations of the DPE wells, trenching, and MTU are illustrated in Figure 2. Operation of the DPE system began in March 2021 and extended through September 2021 when it was intentionally shutdown for reporting and sampling purposes. During that initial operating period, a total of 187,966 gallons (approximately 1,033 gallons per day) of water were extracted, and an estimated 710 gallons of petroleum were removed as vapor. Groundwater sampling and gauging activities were performed on October 4, 2021 and no LNAPL was detected in any of the monitoring wells. The second operational period for the DPE system began when it was restarted on March 17, 2022. 4-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 4 Groundwater Monitoring This section discusses the activities of, and results from, the most recent groundwater monitoring event which was performed on November 8, 2022. A well inventory log and daily activity logs from the event are included as Appendix B. 4.1 Groundwater Gauging AECOM personnel performed a groundwater monitoring event on November 8, 2022. The monitoring event objective was to gauge and sample 17 monitoring wells; however, only 11 monitoring wells (MW-6R, MW-15, MW-19, MW-21, MW-23, MW-29, MW-30, MW-31, MWWB-1, MWWB-2, and MWWB-3) were able to be located and gauged. Monitoring well MW-10R was located but closed with a PVC cap that was unable to be removed and monitoring wells MW-16, MW-24, MW-25, MW-26, and VE-3 were not located. The monitoring wells were opened and allowed to stabilize under atmospheric pressure prior to being gauged with an electronic oil/water interface probe. The average groundwater depth was approximately 12 ft and ranged from 5.45 ft (monitoring well MWWB-1) to 16.04 ft (monitoring well MW-6R). The hydraulic gradient from monitoring well MW-6R to monitoring well MWWB-1 was approximately 0.018 feet-per-foot (ft/ft) in November 2022. A groundwater elevation contour map was generated based on the November 8, 2022 gauging event and is provided as Figure 4. Measurable LNAPL was detected in monitoring well MW-19 at a thickness of 0.02 ft. The interface probe indicated the presence of product at monitoring wells MW-29 and MW-31 but did not indicate the presence of water in both cases so a depth to water (DTW) measurement could not be collected. Without the DTW measurement for monitoring wells MW-29 and MW-31, an LNAPL thickness could not be determined, nor could the presence of LNAPL be confirmed. It should be noted that LNAPL has never been detected in either monitoring well, historically, and LNAPL indication during the event was likely due to malfunctioning equipment. The historical LNAPL thickness and groundwater elevation data which include the most recent event are summarized in Table 4. In addition to groundwater gauging and sampling, AECOM personnel visited the Willowbrook Hosiery basement to collect readings using a photoionization detector (PID). The Willowbrook Hosiery basement is occupied by a fabric washing and drying company. Chemical drums used in the on-site operations were observed in the basement. Poor housekeeping practices including spilled materials were observed during the visit. However, AECOM personnel did not observe any detections when collecting PID readings within the breathing space. 4.2 Groundwater Sampling Methods During the November 8, 2022 groundwater monitoring event, eight monitoring wells were sampled including monitoring wells MW-6R, MW-15, MW-21, MW-23, MW-30, MWWB-1, MWWB-2, and MWWB-3. Monitoring well MW- 19 was not sampled due to the presence of measurable LNAPL and monitoring wells MW-29 and MW-31 were not sampled due to the potential presence of LNAPL. Prior to sample collection, AECOM personnel used disposable bailers to purge three well volumes. Samples were then collected using a clean, disposable bailer. Collected samples were labeled, sealed, and placed on ice in coolers for transportation under chain-of custody protocol to Pace Analytical (Pace), located at 4915 Waters Edge Dr Suite 180, Raleigh, NC 27606, for analysis of volatile organic compounds (VOCs) using the SM 6200B Method. The daily activity logs (Appendix B) document the monitoring well purge volumes and sample collection times. 4.3 Groundwater Analytical Results The laboratory analytical report and chain-of-custody for groundwater samples collected during the November 8, 2022 groundwater monitoring event are provided in Appendix C. Monitoring well MW-21 was the only monitoring well sampled that exhibited a CoC concentration exceeding the GCL. Several of the sampled monitoring wells exhibited CoC concentrations above the 2L Standard. Details of the analytical CoC exceedances are summarized below: 4-2 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 • Benzene exceeded the 2L Standard in seven of the eight monitoring wells which included monitoring wells MW- 6R, MW-15, MW-21, MW-23, MW-30, MWWB-1, and MWWB-3.

A summary of the analytical results from the November 8, 2022 groundwater monitoring event is provided in Table 5. The historical analytical results for the Site are provided in Table 6. 5-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 5 Corrective Action 5.1 Description A full-scale DPE system was constructed at the Site between September 2020 and March 2021. The DPE system uses a high-powered vacuum pump to collect impacted groundwater and soil vapor for treatment and discharge. The DPE system consists of six extraction wells connected to a mobile treatment unit (MTU) through three manifolds. The extraction wells (DPE-01 through DPE-06) are located along the residential apartment complex west of the Site, and the MTU is located in a fenced area behind the store (Figure 2). The MTU contains a vacuum pump, a water/vapor separator tank, two transfer pumps, an oil/water separator, a low-profile diffuser-type air stripper, bag filters, and an active carbon filtration system. The DPE system discharges treated liquid to the publicly owned treatment works (POTW) under a wastewater discharge permit obtained from the City of Burlington. The wastewater discharge permit was renewed on June 15, 2022 and now has a new expiration date of June 16, 2027. Appendix D provides the DPE Piping and Trenching Layout map, DPE MTU Layout, DPE P&ID, and the wastewater discharge permit. 5.2 Objectives The DPE system was implemented to reduce groundwater CoC concentrations and remove LNAPL at the Site and nearby properties to ultimately progress the Site towards risk-based closure. Historically, benzene has been the CoC that repeatedly exceeded the GCL. 5.3 Operation and Maintenance Routine inspections of, and necessary maintenance on, the DPE system were conducted bi-weekly. The routine inspections included the following: • Inspect the DPE system and MTU conditions. • Record applied vacuum at DPE banks and wells. • Record air flow at the DPE air stack and flow meter reading for the treated liquid discharge to the POTW. • Record DPE equipment data (e.g., operating hours, temperature, airflow, etc.). • Remote system response and alert monitoring. • Regular maintenance (e.g., changing oil, replacing bag filters and carbon filter media, inspecting pumps and liquid level controls, etc.). • Collection of air stack samples and treated liquid discharge samples. Monitoring data collected during routine inspections was recorded on system inspection forms and then transferred to an operation and maintenance (O&M) table log for performance tracking purposes. The O&M table log and a copy of the inspection form are provided in Appendix E. The operational data is summarized below: • The operational period for the DPE system began on March 17, 2022 and ended on September 14, 2022 (181 days). • The DPE system operated for a total of 3,985.2 hours resulting in a runtime efficiency of 92 %. • The DPE blower operated at an average vacuum of 12.7 inches of mercury (in-Hg). • The DPE blower operated at an average flowrate of 68 standard cubic feet-per-minute (scfm). • The total volume of groundwater recovered and treated by the DPE system was 120,603 gallons. • The DPE system averaged an effective pump rate of 726.3 gpd, or 0.50 gallons-per-min (gpm). 5.4 Monitoring and Performance As stated earlier, the second operating period began on March 17, 2022 and extended through September 14, 2022. Air stack samples were collected on a monthly basis resulting in a total of seven air stack samples collected during the operating period. The samples were collected from a sample port located on the piping influent to the DPE vacuum pump. All collected samples were shipped under chain-of-custody control to Pace. The Air stack samples were analyzed for VOCs by Method TO-15 or Method M18-Mod A summary of the analytical results for the air stack 5-2 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 sampling during the operating period is provided in Table 7. The laboratory analytical reports and chain-of-custody records for the air stack effluent samples are included in Appendix C. Treated liquid discharge samples were collected on a quarterly basis. A total of three treated liquid discharge samples were collected during the operating period which were analyzed for mercury by Method 245.1, metals by Method 200.8, and VOCs by Method 624.1. The samples were collected from a sample port located on the effluent piping near the flow totalizer and then shipped under chain-of-custody control to Pace. The previously mentioned wastewater discharge permit (Appendix D) defines the treated liquid discharge sampling quarters. The third discharge sampling event did not occur within the third quarter as defined by the permit. Therefore, a fourth discharge sample was collected on October 10, 2022 to satisfy the quarterly reporting permit requirements. The discharge sample was collected after the system shutdown and was analyzed for pesticides by United States Environmental Protection Agency (EPA) 608.3, diesel and oil range organics by EPA 8015C, gas range organics by EPA 5030B/8015C, cadmium by EPA 200.7, mercury by EPA 245.1, metals by EPA 6010D, semi volatile pollutants by EPA 625.1, and volatile organics acrolein by EPA 624.1. A summary of the analytical results for the treated liquid discharge sampling during the operating period is provided in Table 8. The laboratory analytical reports and chain-of-custody records for the treated liquid discharge samples are included in Appendix C. Contaminant mass removed as vapor during the operational period was calculated based on assumptions and inputs which are defined in Table 7. The calculations provide an estimate of the contaminant mass removed based on the following considerations: • Airflow rates were measured at the air stack using a handheld anemometer. • The makeup air valve was not adjusted during air stack sampling in order to capture the most representative sample of influent concentrations during typical operation. • Airflow rates and analytical samples collected from the air stack are instantaneous measurements which are used to average the variable nature over extended periods of time during system operation. Based on the contaminant mass removal calculations performed using the assumptions and inputs defined in Table 7 and the considerations above, a total of 320.39 gallons of petroleum were removed as vapor. The 320.39 gallons exhibits a decrease in total mass removal when compared to the initial operating period which resulted in 710 gallons of petroleum removed as vapor (MAA, 2021a). The decrease could be due to a combination of several factors such as differences in operational methods, contaminant mass reduction by the DPE system operation, or differences in airflow measurement and sampling techniques. One similar trend between the initial operating period and the recent operating period is that the mass removal efficiency increased as the DPE system continued to operate. For example, the DPE system removed petroleum at an estimated 0.97 gpd during the first month of the operating period and an estimated 4.01 gpd during the last month of the operating period. The increase in removal efficiency overtime appears to be mainly due to increasing influent concentrations which may be due to influence from the system drawing contaminant mass to the extraction wells from the surrounding formation. Based on these increasing trends, the stoppage of DPE system operation after six months occurred when the system was most effective during both operating periods. Contaminant mass removed as liquid could not be estimated because influent samples were not collected during the operating period. However, a total of 120,603 gallons of petroleum impacted groundwater was recovered and treated by the DPE system during the operating period. The total volume of recovered groundwater exhibits a decrease when compared to the initial operating period which resulted in 187,966 gallons (MAA, 2021a) even though the DPE system had a higher runtime efficiency (92% versus 82%) during the recent operating period. This may be due to differences in operational methods. For example, the makeup air valve was adjusted several times during the recent operating period to reduce the vacuum applied to the DPE wells. Although, no LNAPL was recovered by the DPE system during the operating period, measurable LNAPL was detected in monitoring well MW-19. No LNAPL was observed in any of the monitoring wells during the groundwater monitoring event performed after the initial operating period on October 4, 2021 (MAA, 2021b). This may further suggest that contaminant mass in the surrounding formation is being mobilized by the DPE system toward the extraction wells. 6-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 6 Conclusions and Recommendations The activities conducted during the second DPE system operating period (March 2022 through September 2022) are summarized as follows: • AECOM personnel conducted groundwater gauging activities for 11 monitoring wells and groundwater sampling activities for eight monitoring wells. • DPE system O&M was conducted on a routine and as-needed basis to maintain system operation. • Air stack samples and treated liquid discharge samples were collected from the DPE system on a routine basis. Based on the observations and results from the second DPE system operating period that are detailed in this report, AECOM concludes the following: • Several CoCs were detected in groundwater at concentrations exceeding the 2L Standards. • Benzene was detected in monitoring well MW-21 at a concentration exceeding the GCL. • Measurable LNAPL was present in monitoring well MW-19 at a thickness of 0.02 ft. • The DPE system operated with a runtime efficiency of 92%. • The DPE system recovered and treated 120,603 gallons of petroleum impacted groundwater at an average effective pump rate of 726.3 gpd. • Mass removal calculations estimated 320.39 gallons of petroleum were removed as vapor by the DPE system. • Mass removal efficiency of the DPE system appears to increase overtime through continuous operation. • The DPE system may be mobilizing contaminant mass towards the extraction wells from the surrounding formation. Based on these conclusions, AECOM, on behalf of Speedway recommends the following: • Continue operating the DPE system. Extend the operational period from six months to 12 months in order to further evaluate the increasing trends of mass removal efficiency over time. • Perform semi-annual groundwater sampling while the DPE system is operating in order to evaluate the effects of the system on localized groundwater elevations (e.g., radius of influence, groundwater drawdown, and cones of depression) and groundwater CoC concentrations. The first event should occur after six months of operation and the second event should occur after 12 months of operation. • Continue to perform monthly air stack sampling of the DPE system. • Continue to perform quarterly sampling of the DPE system treated liquid discharge. • Collect influent liquid samples during the quarterly discharge sampling in order to further evaluate and monitor mass removal as liquid and air stripper/active carbon treatment efficiency. • Generate and submit a CAPR after 12 months of operation summarizing the results and conclusions after implementation of the above recommendations. 7-1 Speedway 6958 Burlington, NC Corrective Action Performance Report January 2023 7 References City of Burlington, Planning Dept., 2022.

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 EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1475124 03/29/22 12:04 12 of 14 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1475124 03/31/22 09:58 12 of 14 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1475124 03/29/22 12:04 13 of 14 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1475124 03/31/22 09:58 13 of 14 ANALYTICAL REPORT April 03, 2022 Mid-Atlantic - Speedway NC Sample Delivery Group:L1475438 Samples Received:03/25/2022 Project Number:R0583.91 Description:Speedway #6958 Report To:Mr. Jim Young 409 Rogers View Court Raleigh, NC 27610 Entire Report Reviewed By: April 03, 2022 [Preliminary Report] T.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.91 L1475438 04/03/22 16:16 16 of 19 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.91 L1475438 04/04/22 16:59 16 of 19 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.91 L1475438 04/03/22 16:16 17 of 19 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.91 L1475438 04/04/22 16:59 17 of 19 ANALYTICAL REPORT April 28, 2022 Mid-Atlantic - Speedway NC Sample Delivery Group:L1486557 Samples Received:04/27/2022 Project Number:R0583.0C Description:Speedway #6958 Report To:Mr. Jim Young 409 Rogers View Court Raleigh, NC 27610 Entire Report Reviewed By: April 28, 2022 [Preliminary Report] T.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.0C L1486557 04/28/22 10:46 11 of 13 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.0C L1486557 04/28/22 11:52 11 of 13 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.0C L1486557 04/28/22 10:46 12 of 13 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.0C L1486557 04/28/22 11:52 12 of 13 ANALYTICAL REPORT May 10, 2022 Mid-Atlantic - Speedway NC Sample Delivery Group:L1487021 Samples Received:04/27/2022 Project Number:R0593.93 Description:Speedway #6958 Report To:Mr. Jim Young 409 Rogers View Court Raleigh, NC 27610 Entire Report Reviewed By: May 10, 2022 [Preliminary Report] T.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description T8 Sample(s) received past/too close to holding time expiration. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1499584 06/02/22 12:58 7 of 9 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1499584 06/03/22 08:19 7 of 9 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1499584 06/02/22 12:58 8 of 9 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583.84 L1499584 06/03/22 08:19 8 of 9 ANALYTICAL REPORT July 04, 2022 Mid-Atlantic - Speedway NC Sample Delivery Group:L1504501 Samples Received:06/14/2022 Project Number:R0583 Description:Speedway #6958 Report To:Mr. Jim Young 409 Rogers View Court Raleigh, NC 27610 Entire Report Reviewed By: July 04, 2022 [Preliminary Report] T.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J4 The associated batch QC was outside the established quality control range for accuracy. V The sample concentration is too high to evaluate accurate spike recoveries. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583 L1504501 07/04/22 08:55 14 of 17 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583 L1504501 07/04/22 11:13 14 of 17 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583 L1504501 07/04/22 08:55 15 of 17 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R0583 L1504501 07/04/22 11:13 15 of 17 #=CL# July 27, 2022 LIMS USE: FR - MARIANNE LINK LIMS OBJECT ID: 92616976 92616976 Project: Pace Project No.: RE: Marianne Link AECOM 5438 Wade Park Boulevard Suite 200 Raleigh, NC 27607 Transfeer Speedway Site-6958 B Dear Marianne Link: Enclosed are the analytical results for sample(s) received by the laboratory on July 19, 2022.

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 EPAMethod 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.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

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 EPAMethod 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 Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.D3 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated samples may be biased high.L1 Analyte recovery in the laboratory control sample (LCS) was below QC limits. Results for this analyte in associated samples may be biased low.L2 Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.M0 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 The EPA or method required sample preservation degrades this compound, therefore acceptable recoveries may not be achieved in sample matrix spikes.P5 RPD value was outside control limits.R1 Surrogate recovery outside laboratory control limits.S0 Surrogate recovery exceeded laboratory control limits. Analyte presence below reporting limits in associated sample.S3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 10/20/2022 08:59 AM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 28 of 32 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92630529 7-Eleven 6958 Burlington Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92630529001 729632 729885EFFLUENTEPA 608.3 EPA 608.3 92630529001 729578 729756EFFLUENTEPA 3511 EPA 8015C 92630529001 729579 729757EFFLUENTEPA 3511 EPA 8015C 92630529001 729734EFFLUENTEPA 5030B/8015C 92630529001 729971 730057EFFLUENTEPA 200.7 EPA 200.7 92630529001 729698 729940EFFLUENTEPA 245.1 EPA 245.1 92630529001 730072 730140EFFLUENTEPA 3010A EPA 6010D 92630529001 729455 729630EFFLUENTEPA 625.1 EPA 625.1 92630529001 729751EFFLUENTEPA 624.1 92630529001 729520 729837EFFLUENTSM 4500-CN-E-2011 SM 4500-CN-E-2011 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 10/20/2022 08:59 AM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 29 of 32 Page 30 of 32 Page 31 of 32 Page 32 of 32 AECOM Appendix D – DPE System Drawings and Wastewater Permit SCALE IN FEET:3030060686627DATE:DRAWN BY:REVIEWED BY:PROJECT NO.:NOTE: ALL MAP FEATURES ARE APPROXIMATEIN SCALE AND LOCATION.C:\Confidential\AECOM\7-Eleven\Sites Folders\North Carolina\6958 Burlington\6958 Burlington.dwg, 9/15/2022 5:55 PM, Dumitru, Ionut, PDF995.pc3, User32767, 1'-0" = 1'-0"NI.
