On October 1, 2014, Speedway LLC acquired the site from Hess Corporation, who had previously acquired the site from WilcoHess LLC. The site is currently in use as a convenience store and retail petroleum dispensing facility. The facility operates three 12,000-gallon gasoline USTs, one 12,000-gallon diesel UST, and one 10,000-gallon kerosene UST. The layout of the facility is shown on Drawing 1.2. Gasoline free product was historically present on the water table in monitoring wells MW-1 and MW-8.Free product, which had not been detected in MW-1 since August 2011, was present in the well during Mid-Atlantic's June 8, 2021 groundwater monitoring event. Prior to the start of a Mobile Multi Phase Extraction (MMPE) event on MW-1 on November 15, 2021, free product was also detected in MW-8 for the first time since August 2012. The site is currently classified as intermediate risk due to the presence of a downgradient surface water body (UT to Lower Creek) located within 500 feet of the source area of the release. The UT to Lower Creek is located approximately 125 feet south and hydraulically downgradient of the source area of the release, and petroleum-related constituents have historically been detected in surface water samples collected from this drainage feature at concentrations exceeding the North Carolina Surface Water Quality Standards (NCSWQS). The approximate surface water sampling locations are identified on Drawing 1.2. Selected historical site assessment data is included in Appendix A. A Trust Fund Pre-Approval Task Authorization (TA #25) was obtained from NCDEQ on November 2,2021 and covered the sampling and laboratory analysis of six groundwater monitoring wells and three surface water points.This report documents the results of the groundwater monitoring and surface water sampling activities conducted at the site on December 20, 2021. The opinions included herein are based on our experience and information obtained during the study. This report is based on limited observations made on the dates noted using procedures described herein. If additional information becomes available, we request the opportunity to review the information, reassess the potential environmental concerns, and modify our conclusions, if appropriate. 2.0 SITE HISTORY AND SOURCE CHARACTERIZATION 2.1 UST Information According to the UST Section’s Registration database, the site’s Facility I.D. number is 0-033119. The following table summarizes the UST system information. Tank No.Const. Type Install Date Size (Gallons)Status Last Contents Previous Contents (If Any) 1 Steel 11/1/1989 12,000 In Use Gasoline None 2 Steel 11/1/1989 12,000 In Use Gasoline None 3 Steel 11/1/1989 12,000 In Use Gasoline None 4 Steel 11/1/1989 12,000 In Use Diesel None 5 Steel 11/1/1989 10,000 In Use Kerosene None 2.2 UST System Owner/Operator The UST system is owned and operated by Speedway LLC. 2.3 Information on Source of Release It appears that a release originally occurred from the gasoline tanks based on impacted soil and the historical presence of free product near the gasoline USTs. The causes and dates of the original release(s) are unknown. Subsequently, Mid-Atlantic visited the site on June 8, 2021 to perform semi-annual groundwater and surface water sampling and discovered approximately four feet of free product in MW-1. Testing of the UST system was subsequently conducted by Crompco, LLC on June 10, 2021 and the regular unleaded gasoline line as well as the premium unleaded gasoline spill bucket did not pass the tests. The line failure occurred across the manifold in the former midgrade unleaded piping run.Tideland Construction capped the line at the dispenser and former midgrade unleaded STP.Crompco re-tested the regular unleaded line after repairs and obtained passing results on June 14, 2021.Although the spill bucket failed the hydrostatic testing, it is not believed to be a significant contributor to the free product found in well MW-1. An MMPE event was scheduled for December 6 - 10, 2021 to extract free product from MW-1. Significant free product (3.79 ft) was detected in MW-1 immediately prior to the beginning of the MMPE. In addition MW-8, which has not had measurable free product since August 2012,was found to contain approximately 3.48 ft immediately prior to the beginning of the MMPE. The presence of free product is likely related to the above described petroleum release that occurred from an abandoned, capped product Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 2 line that was still connected to an active dispenser. That line was repaired/disconnected and subsequent soil sampling was performed, as outlined in Mid-Atlantic's report dated September 20, 2021. A selection of downgradient, off site wells (MW-11, MW-15, and MW-16) were gauged immediately prior to the MMPE on December 6, 2021 to confirm free product was not migrating off site. Free product was not present in the aforementioned wells. At the conclusion of the MMPE event, the remaining down/cross gradient wells (MW-2, MW-13, and MW-14) were gauged and free product was not found. 2.4 Regional Geology and Hydrogeology According to the map titled Geology of North Carolina (1985), prepared by the North Carolina Geological Survey Section of the NCDEQ, the subject site is located in the intrusive rocks of the Inner Piedmont physiographic province. The site appears to be located on top of metamorphic rocks described as “Migmatitic Granitic Gneiss - foliated to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.” Groundwater in the North Carolina Piedmont region is typically found within the pore spaces of the saprolite and alluvium deposits and within the fractures of the underlying bedrock. In general, larger quantities of groundwater are available in valleys and low‑lying areas where saprolite thickness is usually greater. 2.5 Site Geology and Hydrogeology Refer to the historical documents in Appendix A for a summary of the geological and hydrogeological parameters encountered during performance of the site activities as well as the soil boring logs and well construction logs for the well system. Measurements taken during historical site activities indicate the following conditions: •Groundwater flow across the site is generally toward the south-southwest; •The horizontal seepage velocity for shallow groundwater at the site is estimated at approximately 98 feet/year; •The vertical hydraulic gradient is approximately 0.046 foot/foot downward; and •The hydraulic conductivity was estimated to be 0.18 feet/day. 3.0 POTENTIAL RECEPTORS Receptor information for the site was previously documented in Mid-Atlantic’s Phase I Limited Site Assessment Report dated November 13, 2006.A receptor survey update was not conducted during this monitoring event. Please refer to previous reports for detailed receptor information. As indicated, the site is currently classified as Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 3 “intermediate” risk due to the presence of free product on the water table and the existence of a surface water body (UT to Lower Creek)located approximately 125 feet south and hydraulically downgradient of the release area (Drawing 1.2). According to Classifications and Water Quality Standards Assigned to the Waters of the Yadkin-Pee Dee River Basin, Lower Creek is classified as a Class C Water. A Class C Water is defined as a freshwater body that must be protected for secondary recreation, fishing, aquatic life including propagation and survival, and wildlife. 4.0 FIELD ACTIVITIES 4.1 Liquid Level Measurements Mid-Atlantic personnel collected groundwater level measurements from selected site monitoring wells MW-1, MW-3, MW-8, MW-11, MW-15, and MW-16 on December 20, 2021 using an oil/water interface probe. During well gauging, free product was encountered in MW-1 (0.14 ft) and MW-8 (0.04 ft). Monitoring well construction details are provided in Table 4.1. Groundwater level measurements were collected using the procedures outlined in Appendix B. The results of these activities, along with historical measurements, are summarized in Table 4.2. 4.2 Monitoring Well Sample Collection Mid-Atlantic personnel collected groundwater samples from four of six selected site monitoring wells (MW-3, MW-11, MW-15, and MW-16) on December 20, 2021. Free product was present in MW-1 and MW-8 and samples were not collected from these wells. The sampling event was conducted to monitor plume concentrations in the vicinity of the source area of the release (MW-1, MW-3 and MW-8) and immediately upgradient of the receiving UT to Lower Creek (MW-11, MW-15 and MW-16). Groundwater samples were collected using the procedures outlined in Appendix B. Samples were shipped to Pace Analytical in Mt. Juliet, Tennessee and analyzed by the methods shown on the chain-of-custody record provided in Appendix C. 4.3 Surface Water Sample Collection On December 20, 2021,Mid-Atlantic personnel collected three surface water samples from the UT to Lower Creek, located to the south and downgradient of the source area of the release. The approximate sample locations (Stream #1, Stream #2, and Stream #3) are shown on Drawing 1.2.Surface water samples were collected using the procedures outlined in Appendix B. Samples were shipped to Pace Analytical in Mt. Juliet, Tennessee and analyzed by the methods shown on the chain-of-custody record in Appendix C. Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 4 5.0 DISCUSSION OF SAMPLING RESULTS 5.1 Summary of Analytical Results Groundwater The laboratory analytical report and chain-of-custody record for groundwater samples collected on December 20, 2021 are provided in Appendix C and summarized in Table 5.1, which also includes a summary of historical groundwater sampling data for selected target compounds.Free product was detected in MW-1 and MW-8 during gauging activities and samples were not collected from these wells. The groundwater sample collected from monitoring well MW-3 exhibited benzene concentrations above the NCGQS and the sample from MW-16 was found to contain naphthalene above the NCGQS (note: the naphthalene concentration was a "J" value, or estimated value).No other samples collected during the monitoring event exceeded the NCGQS. Exceedances of the NCSWQS were not measured in groundwater samples collected from the wells. Surface Water The laboratory analytical reports and chain-of-custody records for surface water samples collected on December 20, 2021 are provided in Appendix C and summarized in Table 5.2, which also includes a summary of historical surface water sampling data for selected target compounds. As summarized, target compounds were not detected in surface water samples Stream #1, Stream #2, or Stream #3 at concentrations in excess of their applicable NCSWQS or EPA NWQC for the December 20, 2021 sampling event. 5.2 Description of Current Plume Size and Location Until this recent groundwater sampling event, free product had not been detected in MW-8 since August 2012. During the previous groundwater monitoring event in June 2021, free product was detected in MW-1 for the first time since August 2011.Dissolved-phase groundwater contaminants appear to have been migrating hydraulically downgradient of the source area of the release, in the direction of the UT to Lower Creek.The dissolved-phase groundwater contaminant plume appears to be defined by the current monitoring well network to the extent of ten times the NCSWQS, as concentrations did not exceed ten times the NCSWQS for samples collected from monitoring wells MW-11, MW-15 or MW-16, located immediately upgradient of the UT to Lower Creek. Benzene and toluene isoconcentration maps for the December 20, 2021 sampling event are provided as Drawings 5.1 and 5.2, respectively. When compared with the results of previous sampling events, the groundwater contaminant concentrations appear to be generally consistent with more recent sampling events, with the exception of free product Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 5 in MW-1 and MW-8. The presence of free product is likely related to the above petroleum release described in Section 2.3 that occurred from an abandoned, capped product line that was still connected to an active dispenser. That line was repaired/disconnected and subsequent soil sampling was performed, as outlined in Mid-Atlantic's report dated September 20, 2021. Benzene concentrations decreased in MW-16 to below the NCGQS during this monitoring event. An increase in benzene concentrations in MW-3 to the southeast of the free product plume may indicate that dissolved phase groundwater contaminants are beginning to migrate in this direction. For surface water samples collected from the UT to Lower Creek, target compounds have not been detected in excess of the NCSWQS since September 2014. Based on the current available data, additional monitoring events appear to be warranted to continue to evaluate contaminant trends in the groundwater and the downgradient UT to Lower Creek. 5.3 Additional Monitoring Information •Elevation Comparison of the Water Table to the UT to Lower Creek The elevations of the shallow water table for three monitoring wells (MW-2, MW-11, and MW-12) in the vicinity of the UT to Lower Creek were previously compared to the elevations of two surveyed points in the drainage feature. These activities were documented in Mid-Atlantic’s Groundwater Monitoring and Free Product Recovery Report dated June 15, 2012 and the results of water elevation comparisons since that time are summarized in Table 5.3. As indicated, it appears the bottom of the ditch is lower in elevation than the water table, suggesting that groundwater is discharging into the drainage feature. •Proximity of Plume to Nearest Receptor The nearest surface water body is the UT to Lower Creek, located approximately 125 feet to the south and hydraulically downgradient of the source area of the release. Based on relative elevations of the water table in this area to the bottom of the UT, groundwater appears to be discharging to this drainage feature (Table 5.3). Monitoring wells MW-11, MW-15 and MW-16 are located immediately upgradient of the UT to Lower Creek and thus provide the best data for use in groundwater to surface water comparisons. Therefore, based on the results of the historical sampling events, the dissolved-phase groundwater contaminant plume appears to be migrating off-site and discharging to the UT to Lower Creek. •Groundwater Flow Direction Groundwater flow direction in the surficial aquifer was determined by development of a water table contour map (Drawing 5.3) based upon water table elevation data obtained from select site monitoring wells on December 20, 2021. Interpretation of the water Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 6 level data for the current sampling event suggests that the groundwater flow direction is primarily towards the southwest, with a hydraulic gradient (measured from MW-8 toward MW-15) of approximately 0.066 ft/ft. The hydraulic gradient was calculated using the procedure discussed in Appendix B. 6.0 FUTURE SITE REMEDIATION The site is currently ranked intermediate risk due to the presence of free product on the water table and the existence of a surface water body within 500 feet of the source area of the release. The UT to Lower Creek is located approximately 125 feet south and hydraulically downgradient of the release, and petroleum-related constituents have historically been detected in the surface water samples collected from this drainage feature (note that these constituents have not been detected in concentrations exceeding the NCSWQS since September 2014). During semi-annual groundwater sampling on June 8, 2021, free product was discovered in MW-1 for the first time since August 2011. Immediately prior to an MMPE event that began on December 6, 2021, free product was measured for the first time in MW-8 since August 2012. The presence of free product is likely related to a June 2021 petroleum release that occurred from an abandoned, capped product line that was still connected to an active dispenser. That line was repaired/disconnected and subsequent soil sampling was performed, as outlined in Mid-Atlantic's report dated September 20, 2021. Wells located off site and down/cross-gradient of the plume were gauged before and after the MMPE event with no free product detected. Additionally, MW-11, MW-15, and MW-16 located downgradient of the plume were sampled during this reporting period and the results for each well were below the NCGQS. The plume appears to be relatively stable and the contaminants do not appear to be causing surface water standard exceedances in the downgradient receptor. Future site remediation should involve continued semi-annual surface water and groundwater sampling, as well as periodic gauging of MW-1 and MW-8 to monitor for the return of free product. Significant return of free product in these wells may warrant additional MMPE events. 7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS The December 20, 2021 groundwater/surface water monitoring activities are summarized as follows: •Groundwater samples were collected from four of six selected site monitoring wells on December 20, 2021 to monitor plume concentrations in the vicinity of the source area of the release; •Free product was present on the water table in wells MW-1 and MW-8 on December 20, 2021. These wells were not sampled;and, Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 7 •A total of three surface water samples were collected from the downgradient UT to Lower Creek, located approximately 125 feet south of the source area of the release. Based on the results of the sampling event, Mid-Atlantic concludes the following: •An increase in benzene concentrations in MW-3 to the southeast of the free product plume may be an indication that dissolved phase groundwater contaminants are migrating in this direction; •Surface water samples collected from the UT to Lower Creek did not exhibit target compound concentrations in excess of the NCSWQS for the current monitoring event. Additionally, target compounds for surface water samples collected from the UT to Lower Creek have not been detected at concentrations exceeding the NCSWQS since September 2014; •When compared with the results of previous sampling events, the groundwater contaminant concentrations appear to be generally consistent with more recent sampling events, with the exception of the presence of free product in MW-1 and MW-8. The presence of free product is likely related to a June 2021 petroleum release that occurred from an abandoned, capped product line that was still connected to an active dispenser and, •The dissolved-phase groundwater contaminant plume is currently defined by the existing monitoring well network to the extent of ten times the NCSWQS. Based on these conclusions, Mid-Atlantic recommends the following: •Continued free product gauging of the site monitoring wells, with the next measurement in February or March of 2022; •Continued free product recovery using MMPE to address free product on the water table in the vicinity of monitoring wells MW-1 and MW-8; •Continued semi-annual groundwater sampling with the inclusion of wells MW-2,MW-6 and MW-7 to gain additional information regarding the extent of the contaminant plume; •Continued surface water sampling to monitor the potential for impact to the downgradient surface water receptor;and, •Submittal of this report to the NCDEQ, Asheville Regional Office, UST Section. 8.0 STATEMENTS AND CERTIFICATION The following statements must be included at the closing of the document text, and must display the seal and signature of the certifying P.E. or L.G. in addition to the name and certification number of the company or corporation [See 15A NCAC 2L .0103(e).] NO.DESCRIPTION YES NO 1 Enter the date the monitoring report was due.Not Established.Will this report be submitted after the established due date? Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 24, 2022 Page 8 NO.DESCRIPTION YES NO 2 Was any required information from the above template missing from this report? If the answer to question #1 or # 2 is “YES”, please provide additional information in this cell to explain what was missing and why.

Monitoring Wells Prior to sample collection, each well is purged of three to five standing well volumes or to dryness to remove stagnant water from the well and well bore in an effort to collect samples that are representative of the water quality in the formation surrounding each well. Purging is performed either with a new, polyethylene bailer dedicated to each well, or with a decontaminated pump. Samples are retrieved from the monitoring well using the dedicated bailer. New nylon string is used on each dedicated bailer, and new nitrile sampling gloves are donned prior to purging and sampling of each well. B. Geoprobe “Screen Point Sampler” The screen point sampler is a “grab” sampling device that is driven into the saturated zone and a surrounding metal sheath is retracted, exposing a screen. Groundwater entering the screen is then drawn to land surface through disposable tubing that is placed through the hollow push rods. The sample is collected from the tubing into the appropriate sampling glassware. C. Water-Supply Wells Water samples are typically collected from the available spigot that is nearest to the well. The water is allowed to run at a high flow from the spigot for approximately 10 to 15 minutes to allow the water in the delivery lines to be purged. The sample flow is then reduced and the samples are collected directly into pre-labeled containers as described below. New nitrile sampling gloves are donned prior to sampling of each well. D. Treatment System Influent/Effluent Samples are typically collected from the influent or effluent of pump-and-treat groundwater remediation systems using designated sampling ports in the influent and effluent water transport lines. The water is typically allowed to run for several seconds to clear potential debris in the sampling port. The sample is then collected directly into sampling containers as described below. New nitrile sampling gloves are donned prior to sample collection. II. Preparation for Laboratory Analysis Groundwater samples are decanted directly into laboratory-prepared, pre-labeled, sampling containers, packed in ice, and shipped to a certified laboratory under chain-of- custody control. Laboratory analyses performed on the samples are specified on the chain- of-custody. Surface Water Sampling Procedures I. Sample Collection Surface water samples are collected using properly decontaminated equipment or directly into laboratory-supplied sampling containers. Samples are generally collected at or near a suspected discharge point for contaminated groundwater. In small streams and ditches, samples are collected as close to mid-channel as possible. Samples are not collected from stagnant areas or areas of turbulent flow. II. Preparation for Laboratory Analysis Surface water samples are decanted directly into laboratory-prepared, pre-labeled, sampling containers, packed in ice, and shipped to a certified laboratory under chain-of-custody control. Laboratory analyses performed on the samples are specified on the chain-of-custody. Hydraulic Gradient Determination Procedure The hydraulic gradient, which is a measure of the “steepness” of the water table, is determined by dividing the change in the elevation (in feet) of the water table over the change in horizontal distance (in feet) between two measuring points. Typically, the gradient is determined after the Water Table Elevation Contour Map is prepared. Two wells are typically selected that, when a line is drawn between the wells, the orientation of this line approximates the direction of groundwater flow. The greater the horizontal distance between the lines, the more representative the hydraulic gradient value will be for the site. If two wells are not arranged in line with groundwater flow, the hydraulic gradient can be estimated by performing the same calculation using the contours generated for the groundwater flow direction map. The units for the hydraulic gradient are feet/feet. The hydraulic gradient (measured from MW-8 to MW-15) for the subject site was determined as follows: Gradient = dh/dl = (90.36 – 83.62) / 102 = 0.066 ft/ft where: dh = change in head (more specifically, water table elevation) in feet dl = horizontal distance (in feet) between monitoring wells or other head measurement points.

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. 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.
