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, but has not been detected at the site since September 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 NCSWQS. The approximate surface water sampling locations are identified on Drawing 1.2. Selected historical site assessment data is included in Appendix A. This report documents the results of the groundwater monitoring and surface water sampling activities conducted at the site in November 2020.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. A Trust Fund Pre-Approval Task Authorization (TA #21) was obtained from NCDEQ on September 17, 2020 and covered the sampling and laboratory analysis of six groundwater monitoring wells and three surface water points. This report documents these activities and the results. 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 Based on impacted soil and the historical presence of free product near the gasoline USTs, it appears that a release occurred from these tanks. Although the causes and dates of the release(s) are unknown, it appears that the releases are not on-going, since the UST system passed Precision’s tightness tests and the UST systems have been upgraded to current standards. 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 NCDENR, 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 constructions 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 average horizontal hydraulic gradient across the site is estimated at 0.038 foot/foot; Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 22, 2021 Page 2 •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 “intermediate” risk due to the presence 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 freshwaters 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 November 18, 2020 using an electronic water level indicator. 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 six selected site monitoring wells (MW-1, MW-3, MW-8, MW-11, MW-15, and MW-16) on November 18, 2020. 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. Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 22, 2021 Page 3 4.3 Surface Water Sample Collection On November 18, 2020, 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. 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 in November 2020 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.As summarized, the groundwater sample collected from source area monitoring well MW-1 exhibited an increase in toluene and naphthalene concentrations to an excess of ten times the NCSWQS but below the GCLs. Source area monitoring well MW-8 exhibited benzene, toluene and naphthalene concentrations in excess of ten times the NCSWQS but below the GCLs. No other samples collected during the monitoring event exceeded ten times the NCSWQS, including the wells located immediately upgradient of the UT to Lower Creek (MW-11, MW-15 and MW-16). Surface Water The laboratory analytical report and chain-of-custody record for surface water samples collected in November 2020 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 November 2020 sampling event. 5.2 Description of Current Plume Size and Location Free product has not been detected at the site since September 2012 and dissolved-phase groundwater contaminants appear to have migrated 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 Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 22, 2021 Page 4 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 November 2020 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 MW-1, which exhibited an increasing trend. Since the release was discovered, an overall attenuation of contaminant concentrations appears evident. Target compound concentrations for surface water samples collected from the UT to Lower Creek have not been detected in excess of the NCSWQS since February 2013. Based on the current available data, additional monitoring events appear to be warranted to continue to evaluate contaminant trends associated with wells MW-1, MW-3, MW-8, MW-11, MW-15 and MW-16 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 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 current and 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 Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 22, 2021 Page 5 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 in November 2020. Interpretation of the water 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 0.073 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 surface water within 500 feet of the source area of 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 February 2013). As such, the proposed remedial approach for the site at this time includes continued monitored natural attenuation. Although contaminants are present in groundwater near the downgradient receptor (UT to Lower Creek), the plume appears to be relatively stable and the contaminants do not appear to be causing surface water standard exceedances in the downgradient receptor. If groundwater contaminant concentrations should significantly increase, supplemental remedial measures may be required. In that case, the proposed remedial approach will utilize chemical oxidation technologies to reduce contaminant concentrations within the source area of the release (i.e. the immediate vicinity of wells MW-1 and MW-8) and mitigate the discharge of petroleum-related constituents to the receiving surface waters. Under this approach, monitoring wells MW-11, MW-15, and MW-16 will be used to support the application of ISOC (or similar) and formation of an “oxygen barrier” between the source area of the release and the UT to Lower Creek. 7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS The November 2020 groundwater/surface water monitoring activities are summarized as follows: •Groundwater samples were collected from six selected site monitoring wells on November 18, 2020 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); and •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: Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 22, 2021 Page 6 •Free product was not detected at the site during the November 2020 groundwater monitoring event and has not been detected at the site since September 2012; •The groundwater sample collected from source area monitoring well MW-1 exhibited toluene and naphthalene concentrations in excess of ten times the NCSWQS but below the GCLs.MW-8 exhibited benzene, toluene, and naphthalene concentrations in excess of ten times the NCSWQS but below the GCLs. No other samples collected during the monitoring event exceeded ten times the NCSWQS, including the wells located immediately upgradient of the UT to Lower Creek (MW-11, MW-15 and MW-16); •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 February 2013; •When compared with the results of previous sampling events, the overall groundwater contaminant concentrations appear to be generally consistent with recent sampling events, with the exception of a general increase in concentrations in MW-1. During this sampling event, an increase in benzene, toluene, xylenes, and naphthalene concentrations was observed in the groundwater sample collected from this well. However, since the release was discovered, an overall attenuation of contaminant concentrations appears evident;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 groundwater/surface water monitoring to gain additional information regarding the stability/decay of the contaminant plume and the potential for impact to the downgradient surface water receptor. If the plume remains stable and the NCSWQS are not exceeded, the site should continue to be monitored until NCDEQ can confirm that the site is eligible for risk downgrade; however, if groundwater concentrations increase significantly, the use of chemical oxidation technologies should be considered; 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.January 31, 2020.Will this report be submitted after the established due date? Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina January 22, 2021 Page 7 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. Pertinent available information regarding site groundwater conditions is provided throughout the report and selected historical assessment information is provided in Appendix A. 3 If applicable, will any of the proposed attenuation milestones under the schedule approved in the Corrective Action Plan not be met? (within a reasonable margin of error) not applicable, no Corrective Action Plan in place If the answer to question #3 is “NO”, skip to the certification under #8 below. If the answer to question #3 is “YES”, please generally describe in this cell the possible reason(s) and outline proposed remedies. (This should be described in more detail in the report text above.) Natural attenuation is not currently part of the remedial strategy at this site, although it may be in the future. Remedial efforts to date have focused on removing free product from the water table 4 Does any known or suspected source zone soil contamination or free product remain outside of the assessed area that could be inhibiting natural attenuation?  5 Has there been an unexpected increase in contaminant mass sufficient to suggest a potential new release from a separate onsite or offsite source?  If the answer to either question #4 or #5 is “YES”, generally describe in this cell any actions recommended to further assess or clean up this known or suspected source. Estimated mass calculations indicate fluctuations in volume of free product in the subsurface over time. Ethanol and oxygenates analysis of the free product was performed in December 2018 and the sample did not contain these compounds (were not indicative of a new/ongoing release). Therefore, fluctuations in volume may be related to natural fluctuation of the water table, resulting in fluctuating free product thicknesses. These data are best evaluated as trends over time. Free product thicknesses have remained relatively steady overall since the beginning of 2019. 6 Certification: I,John L.

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 = (91.55 – 84.10) / 102 = 0.073 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.

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 at the site since September 2012, was present in MW-1 during Mid-Atlantic's June 8, 2021 and July 15, 2021 site visits. 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 NCSWQS. The approximate surface water sampling locations are identified on Drawing 1.2. Selected historical site assessment data is included in Appendix A. This report documents the results of the groundwater monitoring and surface water sampling activities conducted at the site on June 8, 2021, aggressive fluid-vapor recovery (AFVR) remedial activities conducted at the site on June 14, 2021, and additional groundwater monitoring and surface water sampling conducted at the site on July 15,2021.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. A Trust Fund Pre-Approval Task Authorization (TA #22) was obtained from NCDEQ on April 14,2021 and covered the sampling and laboratory analysis of six groundwater monitoring wells and three surface water points. Following discovery of free product during sampling events on June 8, 2021, a Trust Fund Pre-Approval Task Authorization (TA #23) was obtained on June 10, 2021 which covered an AFVR event and the sampling of one groundwater monitoring well and surface water points.This report documents the activities and results for the groundwater sampling for both TAs. A separate Free Product Recovery Report will be generated to document the AFVR results. 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. Mid-Atlantic visited the site on June 8, 2021 to perform semi-annual groundwater and surface water sampling at the site 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. Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina September 3, 2021 Page 2 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 NCDENR, 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 constructions 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 average horizontal hydraulic gradient across the site is estimated at 0.038 foot/foot; •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 “intermediate” risk due to the presence 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 freshwaters that must be protected for secondary recreation, fishing, aquatic life including propagation and survival, and wildlife. Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina September 3, 2021 Page 3 4.0 FIELD ACTIVITIES 4.1 Liquid Level Measurements Mid-Atlantic personnel collected groundwater level measurements from selected site monitoring wells MW-3, MW-8, MW-11, MW-15, and MW-16 on June 8, 2021 using an electronic water level indicator. During well gauging free product was discovered in MW-1. A bailer was used to confirm presence of free product which was found to have a thickness of approximately four feet. Mid-Atlantic personnel did not have an oil/water interface probe on site to gauge this well during this sampling event. Utilizing an oil/water interface probe during subsequent sampling on July 15, 2021 free product thickness was measured to be 3.38 feet.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 five of six selected site monitoring wells (MW-3, MW-8, MW-11, MW-15, and MW-16) on June 8, 2021. Free product was discovered in MW-1 and thus was not sampled. 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 June 8, 2021 and July 15, 2021,Mid-Atlantic personnel collected three surface water samples (six surface water samples total)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. 5.0 DISCUSSION OF SAMPLING RESULTS 5.1 Summary of Analytical Results Groundwater Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina September 3, 2021 Page 4 The laboratory analytical report and chain-of-custody record for groundwater samples collected on June 8, 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 during initial measurement activities and thus was not sampled. The groundwater sample collected from monitoring well MW-3 exhibited detectable benzene concentrations above the NCGQS.MW-8 exhibited benzene, toluene, and naphthalene concentrations in excess of ten times the NCSWQS but below the GCLs. No other samples collected during the monitoring event exceeded ten times the NCSWQS, including the wells located immediately upgradient of the UT to Lower Creek (MW-11, MW-15 and MW-16) Surface Water The laboratory analytical reports and chain-of-custody records for surface water samples collected on June 8, 2021 and July 15, 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 either the June 8, 2021 or July 15, 2021 sampling event. 5.2 Description of Current Plume Size and Location Until this recent groundwater sampling event, free product had not been detected at the site since August of 2012 (in well MW-8) and 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 June 8, 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 in MW-1 and an increasing trend in MW-8, MW-15, and MW-16. The increase of groundwater contaminant concentrations appear to coincide with a recent release from the abandoned product line. Although the spill bucket failed the hydrostatic test, it is not believed to be a significant contributor to the free product found in well MW-1. Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina September 3, 2021 Page 5 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 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 current and 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 June 8, 2021. Interpretation of the water 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 0.069 ft/ft. The hydraulic gradient was calculated using the procedure discussed in Appendix B. Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina September 3, 2021 Page 6 6.0 FUTURE SITE REMEDIATION The site is currently ranked intermediate risk due to the presence of surface water within 500 feet of the source area of 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). Free product was discovered in MW-1 on June 8, 2021 during this sampling event.An AFVR event was conducted on June 14, 2021 and is described in a separate report. The proposed remedial approach for the site at this time includes future AFRV events on MW-1. Although contaminants are present in groundwater near the downgradient receptor (UT to Lower Creek), the plume appears to be relatively stable and the contaminants do not appear to be causing surface water standard exceedances in the downgradient receptor. 7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS The June 8, 2021 and July 15, 2021 groundwater/surface water monitoring activities are summarized as follows: •Groundwater samples were collected from five of six selected site monitoring wells on June 8, 2021 to monitor plume concentrations in the vicinity of the source area of the release (MW-3 and MW-8; free product in MW-1) and immediately upgradient of the receiving UT to Lower Creek (MW-11, MW-15 and MW-16); •Free product was discovered during both attempts to collect groundwater sample from MW-1 on June 8, 2021 and July 15, 2021 and thus was not sampled. The free product is believed to have been released from a portion of abandoned product line, which has since been repaired; and •A total of six surface water samples (three on June 8, 2021 and three on July 15, 2021)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: •Free product was detected in MW-1 at the site during the June 8, 2021 groundwater monitoring event; •After the discovery of free product in well MW-1, an AFVR was conducted on the well (results will be reported in a separate report); •MW-8 exhibited benzene, toluene, and naphthalene concentrations in excess of ten times the NCSWQS but below the GCLs. No other samples collected during the monitoring event exceeded ten times the NCSWQS, including the wells located immediately upgradient of the UT to Lower Creek (MW-11, MW-15 and MW-16); Groundwater Monitoring Report Speedway 7972 (Former WilcoHess 353) Lenoir, North Carolina September 3, 2021 Page 7 •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 overall groundwater contaminant concentrations appear to be generally consistent with more recent sampling events, with the exception of free product in MW-1 and an increasing trend in MW-8, MW-15, and MW-16. The increase of groundwater contaminant concentrations appear to coincide with a recent release from the abandoned product line. Although the spill bucket failed the hydrostatic test, it is not believed to be a significant contributor to the free product found in well MW-1; •The new release from the line appears to be commingled with the existing Incident No. 28414; •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 recovery using AFVR; •Continued groundwater water sampling with the inclusion of wells MW-6 and MW-7 to gain additional information regarding the northern extent/source of the plume following the recent release. Also, inclusion of wells MW-2 and MW-12 to gain additional information regarding the southern extent of the plume to downgradient adjacent properties; •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.July 31, 2021.Will this report be submitted after the established due date? 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 = (90.65 – 83.66) / 102 = 0.069 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. 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. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R1760.14 L1363940 06/21/21 13:11 30 of 35 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R1760.14 L1363940 06/21/21 14:47 30 of 35 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 R1760.14 L1363940 06/21/21 13:11 31 of 35 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R1760.14 L1363940 06/21/21 14:47 31 of 35 TURN AROUND TIME Speedway LLC.1/2 https://www.speedway-ids.com TURN AROUND TIME Speedway LLC.2/2 https://www.speedway-ids.com Chain-of-Custody-Record Printed: 06/21/2021 1,1,1,2-Tetrachloroethane ug/L, 1,1,1-Trichloroethane ug/L, 1,1,2,2-Tetrachloroethane ug/L, 1,1,2-Trichloroethane ug/L, 1,1-Dichloroethane ug/L, 1,1-Dichloroethene ug/L, 1,1-Dichloropropene ug/L, 1,2,3-Trichlorobenzene ug/L, 1,2,3-Trichloropropane ug/L, 1,2,4-Trichlorobenzene ug/L, 1,2,4-Trimethylbenzene ug/L, 1,2-Dibromo-3-chloropropane ug/L, 1,2-Dibromoethane ug/L, 1,2-Dichlorobenzene ug/L, 1,2-Dichloroethane ug/L, 1,2-Dichloropropane ug/L, 1,3,5-Trimethylbenzene ug/L, 1,3-Dichlorobenzene ug/L, 1,3-Dichloropropane ug/L, 1,4-Dichlorobenzene ug/L, 2,2-Dichloropropane ug/L, 2-Butanone ug/L, 2-Chlorotoluene ug/L, 4-Chlorotoluene ug/L, 4-Methyl-2-pentanone ug/L, Acetone ug/L, Acrolein ug/L, Acrylonitrile ug/L, Benzene ug/L, Bromobenzene ug/L, Bromodichloromethane ug/L, Bromoform ug/L, Bromomethane ug/L, Carbon tetrachloride ug/L, Chlorobenzene ug/L, Chloroethane ug/L, Chloroform ug/L, Chloromethane ug/L, Dibromochloromethane ug/L, Dibromomethane ug/L, Dichlorodifluoromethane ug/L, Diisopropyl ether ug/L, Ethylbenzene ug/L, Hexachlorobutadiene ug/L, Isopropylbenzene ug/L, Methyl tert butyl ether ug/L, Methylene chloride ug/L, Naphthalene ug/L, Styrene ug/L, Tetrachloroethene ug/L, Toluene ug/L, Trichloroethene ug/L, Trichlorofluoromethane ug/L, Vinyl chloride ug/L, cis-1,2-Dichloroethene ug/L, m,p-Xylene ug/L, n-Butylbenzene ug/L, n-Propylbenzene ug/L, o-Xylene ug/L, p-Isopropyltoluene ug/L, sec-Butylbenzene ug/L, tert-Butylbenzene ug/L, trans-1,2-Dichloroethene ug/L Speedway LLC.1/1 https://www.speedway-ids.com ANALYTICAL REPORT July 20, 2021 Mid-Atlantic - Speedway NC Sample Delivery Group:L1379612 Samples Received:07/16/2021 Project Number:R1760.14 Description:Speedway #7972 Site:7972 Report To:Cameron Moore 409 Rogers View Court Raleigh, NC 27610 Entire Report Reviewed By: July 20, 2021 [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. 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 R1760.14 L1379612 07/20/21 20:23 17 of 24 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R1760.14 L1379612 07/21/21 08:40 17 of 24 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 R1760.14 L1379612 07/20/21 20:23 18 of 24 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R1760.14 L1379612 07/21/21 08:40 18 of 24 1 Alan Harvill From:Cameron Moore <CMoore@maaonline.com> Sent:Monday, July 19, 2021 9:56 AM To:Alan Harvill Subject:RE: Pace Analytical National Login for R1760.14 Speedway #7972 L1379612 CAUTION: This email originated from outside Pace Analytical.
