Speedway 7968, Hickory, NCMobile Multi-Phase Extraction and Groundwater Monitoring Report November 2023 Executive Summary As required by the North Carolina Department of Environmental Quality (NCDEQ), AECOM Technical Services of North Carolina, Inc. (AECOM) on behalf of Speedway, LLC (Speedway) has prepared this Groundwater Monitoring and MMPE Report for former Speedway Store No. 7968 (Site), located at 4431 North Center Street, Hickory, Catawba County, North Carolina (NC). The Site is currently occupied with a convenient store and new gas operations. Speedway gas operations discontinued in March 2021 when the underground storage tank (UST) system was removed. On August 22, 2022, ATC Associates of North Carolina, PC (ATC) (Speedway’s former consultant) submitted a CSA report to NCDEQ. Based on the results of the CSA the plume was not horizontally delineated to the north-northeast. In August 2022 Speedways consultant was changed from ATC to AECOM. In February 2023 AECOM installed three (3) monitoring wells to delineate the benzene plume and to perform a light non-aqueous phase liquid (LNAPL) evaluation on monitoring well MW-03. In February 2023 AECOM oversaw the installation of monitoring wells MW-10, MW-11, and MW-12, installed in the downgradient direction (north-northeast) of the source area. Soil analytical results from the monitoring well installation indicated no contamination above the Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs). Groundwater analytical results for monitoring wells MW-10 and MW-11 indicated the presence of Contaminants of Concern (COCs) above their respective North Carolina Groundwater Quality Standards (2L Standards). During the same time as the monitoring well installation, AECOM attempted to perform a LNAPL evaluation on monitoring well MW-03. On February 7, 2023, the apparent thickness of LNAPL in monitoring well MW-03 was measured at 0.02 feet. An attempt to pull the LNAPL from the monitoring well and measure the rebound was unsuccessful due to the minimal apparent thickness. An absorbent sock was installed in the monitoring well to reduce the presence of LNAPL in the well. LNAPL was not measured in any other monitoring well on Site. A Mobile Multi-Phase Extraction (MMPE )event was conducted from October 2 through October 6, 2023, by Advanced Environmental Services, Inc (Advanced) under the supervision of AECOM field personnel. Monitoring wells MW-01, MW-02, and MW-03 were used as extraction wells for the event. A total of 3,636 gallons of affected groundwater was recovered during the MMPE event. No measurable LNAPL was recovered during the event. Based on mass-removal calculations an additional 1,049.02 pounds of vapor (170.52 gallons) phase hydrocarbons were removed during the MMPE event. On October 2, 2023, thirteen monitoring wells (MW-01 to MW-12 and MW-01D) were gauged by AECOM at the start of the MMPE event and were again gauged by AECOM on October 6, 2023, at the end of the MMPE event. On both sample dates, (October 2, 2023 and October 6 2023, respectively) LNAPL was not present in the monitoring wells. Analysis of the groundwater samples collected on October 16 and October 17, 2023, indicated benzene and other contaminates of concern continue to impact the. GLC was exceeded just for benzene in monitoring wells MW-01 (10,300 ug/L) and MW-08 (12,000), and for tert-Butyl Alcohol (TBA) in monitoring well MW-01 (16,800). LNAPL was detected only in monitoring wells MW-02 during this event with a LNAPL thickness of 0.01 feet. Water level measurements collected from the site indicated that groundwater flow direction corresponded with historical flow direction which has been generally towards the north. AECOM, on behalf of Speedway recommends attempting to abandon the water supply well located north (downgradient) of the Site to reduce the risk ranking from High to Intermediate. Perform a comprehensive groundwater monitoring event to further assess recovery performance and plume stability. Gauge monitoring well MW-02 and MW-03 on a quarterly basis and remove LNAPL/replace absorbent socks as necessary until LNAPL is no longer present within the monitoring well.

Site History and Characterization The following sections provide information on the USTs operated at the Site and follows the general outline established in UST Section Assessment Guidelines (NCDEQ, 2021a), UST Section Corrective Action Guidelines (NCDEQ, 2021b) and Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases (NCDEQ, 2021c) using the Comprehensive Tables for Corrective Action Guidelines Tables (NCDEQ, 2022). 3.1 Underground Storage Tank Systems UST owner operator and other responsible party information are provided in Table 1. A summary of current and former USTs maintained at the Site is provided below and summarized in Table 2. According to the Catawba County, North Carolina Geographic Information System (GIS) mapping service, the current property owner of the subject site is listed as PROPST SUPERETTE #1 LLC. 3.2 Aboveground Storage Tank Systems No aboveground storage tank systems (ASTs) are currently present on site. Based on available information, no ASTs have historically been present at the Site. 3.3 Historical Releases No information on releases is available for this Site. 3.4 Site Characteristics The location of the Site is shown on a portion of the United States Geological Survey (USGS), Topo USGS 7.5 Minute Topographic: Bethlehem, NC (2019) digital raster graphic file (Figure 1). The layout of the Site is found on Figure 2. The Site is currently operational and is occupied by a Speedway convenience store with Speedway gasoline operations. The Site is located at 4431 North Center Street, Hickory, North Carolina and is accessed from North Center Street, located southeast of the Site. Various commercial and residential properties surround the Site. 3.4.1 Zoning/Receptor Information The Site and adjoining properties are currently zoned residential and business (Catawba County GIS, 2023). Receptor information for the site was documented in ATC’s (Speedway’s former consultant) August 19, CSA report (ATC, 2022). A receptor survey update was not completed for this phase of work. For additional details, please refer to the CAP report. 3.4.2 Site Geology and Hydrogeology Site geology was evaluated based on historic (ATC) and current investigations. The site is located within the interlayered rocks of the Carolina Inner Piedmont Belt. The site appears to be located in a predominantly metamorphic rock formation described as “Metamorphosed’. In general, the soils encountered at the Site consist of brown, grey, and orange fine silty clay, becoming moist at depths starting from forty-five feet. Groundwater elevation was encountered at approximately 1,003.43 feet bgs (MW-10) to 1,006.31 feet bgs (MW-05). Based on the results of the October 16, 2023, gauging event, groundwater flow is to the north, which is generally consistent with historical groundwater flow. Historical groundwater elevations are summarized on Table 4, and a groundwater flow map (Figure 3) was constructed based on the October 16, 2023, gauging results. The hydraulic gradient, as measured from monitoring well MW-5 to MW-10, is 0.0157ft/ft [(1,006.31 - 1,003.43)/183.43].

Receptor Information 4.1 Water Supply Wells The previous consultant (ATC) conducted a water supply well survey in 2018 to identify the presence of water supply wells within a 1,500-foot radius from the Site and is documented in ATC’s August 2022, CSA Report. 4.1.1 Private Water Supply Wells Based on the survey, two water supply wells were detected within 1,500 feet of the site. One water supply well is within 520 feet of the site. It is currently inactive, and the property is supplied by municipal water. The second water supply well is active, and it’s used to supply drinking water to a single-family residence 490 feet northeast of the site. This depth of both wells is unknown. 4.1.2 Public Water Systems Municipal water is available to the Site and the surrounding properties and its provided by the City of Hickory Utilities. Water lines run along the public streets in the area. The public water source is Lake Hickory/Catawba River, which are located within 1,500 feet of the subject site. 4.2 Surface Water No surface water was observed on the Site. The nearest off-site surface water are Falling Creek observed approximately 1,700 feet south of the site and Lake Hickory/Catawba River was observed approximately 1,200 feet northeast of the site, as well as 1,400 feet northwest of the site. 4.3 Wellhead Protection Areas According to the NCDEQ Well Head Protection website, last updated in October 2023, there are no approved wellhead protection plans located in Catawba County. AECOM 5-5 Speedway 7968, Hickory, NCMobile Multi-Phase Extraction and Groundwater Monitoring Report November 2023 5. MMPE Event This section discusses the LNAPL gauging and MMPE conducted from October 2 to October 6, 2023 by Advanced under the supervison of AECOM. 5.1 Groundwater Gauging Historical gauging information is summarized in Table 4. AECOM personnel gauged monitoring wells MW-1, MW-2 and MW-3 on October 6, 2023, after the MMPE event finished. LNAPL was not found in any monitoring wells. One groundwater gauging event was conducted post-MMPE event on October 16, 2023, including monitoring wells MW-01, MW-02, MW-03, MW-04, MW-05, MW-06, MW-07, MW-08, MW-09, MW-10, MW-11, MW-12 and MW-01D. Following the MMPE event, no LNAPL was idenfied in any of the gauged monitoring wells. Advanced’s Mobile Multi-Phase Extraction Report is attached as Appendix B 5.2 MMPE Field Activities During this monitoring period, Advanced was contracted by AECOM to conduct a 96-hour MMPE event from October 2, 2023, to October 6, 2023, to extract LNAPL and vapors from monitoring wells (MW-1, MW-2, and MW-3) that historically have had measurable LNAPL. During the event a total of 3,636 gallons of liquids were removed during the event. No measurable free product was recovered during the event. Based on 96 hours of operation, the average liquid recovery rate was 37.83 gallons-per-hour. Based on mass removal calculations, 1,049.02 pounds or 170.52 gallons of vapor phase hydrocarbons were removed. Following the event, no LNAPL was identified in monitoring wells. A copy of the MMPE report and calculations has been included as Appendix A. AECOM 6-6 Speedway 7968, Hickory, NCMobile Multi-Phase Extraction and Groundwater Monitoring Report November 2023 6. Groundwater Investigation During the current monitoring period, activities included groundwater gauging and sampling. 6.1 Groundwater Gauging Monitoring wells MW-01, MW-02, MW-03, MW-04, MW-05, MW-06, MW-07, MW-08, MW-09, MW-10, MW-11, MW-12 and MW-01D, were gauged for depth to water and depth to LNAPL (if present). Depths to groundwater ranged from 41.34 feet bgs (MW-10) to 53.07 feet bgs (MW-05) in wells where LNAPL was not encountered. The only well where LNAPL was encountered was MW-02 with a depth to groundwater of 52.79 ft bgs. 6.2 Groundwater Sampling Prior to the collection of a groundwater sample for laboratory analysis, the depth to liquid or LNAPL was measured using an electronic oil-water interface probe. If no LNAPL was present, the well was purged of at least three well volumes using a disposable bailer. Depth to water and calculated groundwater elevations for the current and historic gauging events are included on Table 4. 6.3 Groundwater Analytical Results  During this monitoring period, monitoring wells MW-01, MW-03, MW-04, MW-05, MW-06, MW-07, MW-08, MW-09, MW-10, MW-11, MW-12 and MW-01D were sampled on October 16, 2023, and October 17, 2023, and analyzed for volatile organic compounds (VOCs) via United States Environmental Protection Agency (EPA) Method SM 6200B and EPA 6010. Monitoring well MW-2 was not sampled due to measurable LNAPL.  Once the wells had been properly purged, natural attenuation parameter readings were collected using a Yellow Spring Instruments (YSI) meter and groundwater samples were collected from each location using dedicated disposable polyethylene bailers attached to nylon rope. To collect a sample, the bailer was slowly lowered to a depth just beneath the water surface in the well. The bailer was then recovered, and the contents carefully decanted into laboratory supplied sample containers, properly preserved, and delivered to Pace Analytical (Pace), a North Carolina-certified laboratory. Groundwater sampling results indicated petroleum hydrocarbon continued to impact the Site monitoring wells during this reporting period. - Benzene concentrations were observed in monitoring wells MW-01 and MW-08 above the GCL (5,000 ug/L) in site monitoring wells at concentrations of 10,300 ug/L and 12,000 ug/L, respectively. - TBA concentration in monitoring wells MW-01 exceeded the GCL (10,000 ug/L) in site with a concentration of 16,800 ug/L. - No other compounds exceeded GCLs. Analytical results are summarized in Table 5. Dissolved benzene iso-concentration map, October 2023 sampling event are included as Figure 4. Laboratory analytical reports are included in Appendix A. AECOM 7-1 Speedway 7968, Hickory, NCMobile Multi-Phase Extraction and Groundwater Monitoring Report November 2023 7. LNAPL Investigation and Recovery LNAPL has historically been observed in monitoring well MW-03. This section discusses gauging and historical LNAPL recovery. 7.1 LNAPL Gauging Historical gauging information is summarized in Table 4. During the current monitoring period, apparent LNAPL thickness was gauged on October 16, 2023. LNAPL was detected in monitoring well MW-02 at a thickness of 0.02 ft. The LNAPL thickness historically present in monitoring well MW-03 was not detected during the current activities. AECOM 8-2 Speedway 7968, Hickory, NCMobile Multi-Phase Extraction and Groundwater Monitoring Report November 2023 8. Discussion The following is an analysis of the October 2023 MMPE event and groundwater sampling event from October 16 and 17, 2023. Based on the results of the October 2023 activities:  The MMPE event recovered approximately 170.52 gallons of LNAPL (0 gallons of liquid LNAPL and 170.52 gallons of LNAPL as vapor).  Apparent LNAPL thickness in monitoring well MW-03 during the previous event was recorded at 0.02 ft; pre- MMPE and post-MMPE was recorded at 0.00 ft and during the October 2023 groundwater monitoring event at 0.00 ft.  During the October 16, 2023, groundwater monitoring event, MW-02 was the only monitoring well with LNAPL present (0.01 ft).  The only compounds that exceeded GCLs are benzene in monitoring wells MW-01 (10,300 ug/L) and MW- 08 (12,000) and TBA in monitoring well MW-01 (16,800).  Water level measurements collected from the site indicated that groundwater flow direction corresponded with historical flow direction which has been generally towards the north. AECOM, on behalf of Speedway recommends the following additional actions:  Attempt to abandon the water supply well located north (downgradient) of the Site to reduce the risk ranking from High to Intermediate.  Perform a comprehensive groundwater monitoring event to further assess recovery performance and plume stability.  Gauge monitoring well MW-02 and MW-03 on a quarterly basis and remove LNAPL/replace absorbent socks as necessary until LNAPL is no longer present within the monitoring well. 9.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

The MMPE system was active for 96.0 hours. During the event, vacuum at the recovery pump ranged from 20.0 to 23.0 inches of mercury (hg) and stabilized at approximately 22.0 inches of mercury. Airflow rates ranged from 1,100 to 1,250 feet per minute and stabilized at approximately 1,150 feet per minute. System temperature ranged from 120.0 – 134.0 degrees F and humidity ranged from 46.0 to 60.0 percent. Field gauged volatile organic compounds (VOC’s) decreased from 34,000 parts per-million (PPM) to 17,000 (PPM) throughout the event. Groundwater / Product Mix Recovered: During the event a total of 3,636 gallons of product/water mix were removed from the site and properly disposed at a certified North Carolina disposal facility. No measurable free product was recovered during the event. Total fluids recovered, was measured based on stick readings conducted during and following the event. Based on 96.0 hours of operation and a total of 3,636 gallons recovered, the average groundwater recovery rate was calculated to be approximately 37.87 gallons per hour. Events Results: Based on mass-removal calculations 1,049.02 pounds or 170.52 gallons of VOC’s were removed as vapor. Following the event, no free product was identified in any well.
