The site is a closed petroleum retail facility and convenience store and contained four underground storage tanks (USTs) total: three 10,000-gallon capacity USTs (regular gasoline, premium gasoline, and diesel fuel) and one 6,000-gallon capacity UST (kerosene). The three 10,000-gallon capacity USTs were located to the north of the building and dispensers, and the one 6,000-gallon capacity UST was located to the east.The site topographic location is shown on Drawing 1.1, and the site drawing with the approximate locations of the USTs is presented as Drawing 1.2. UST closure activities were performed in February 2019. During the tank closure, petroleum impact was identified in the overburden of the three 10,000-gallon tanks. The impacted material was segregated and disposed of offsite at an approved facility. On February 28, 2019, diesel fuel contamination was encountered in the vicinity of the diesel dispenser during the UST closure activities. Initial soil sampling confirmed the release and initial abatement measures were taken. Approximately one ton of impacted soil was excavated and disposed of at the A&D Environmental (A&D) facility in High Point, North Carolina. The extent of the excavation was limited due to the structural concerns of undermining the canopy. Drawing 1.2 shows the location of the former UST basins, product lines, diesel dispenser (source area), and monitoring wells. A 24-Hour Release and UST Leak Reporting Form was submitted to the North Carolina Department of Environmental Quality (NCDEQ) by Mid-Atlantic on March 1, 2019. A UST Closure and Initial Abatement Action Report was submitted on June 3, 2019. The NCDEQ issued a Notice of Regulatory Requirements on June 24, 2019 requiring the completion of a Limited Site Assessment (LSA). Based on the results of the LSA, NCDEQ classified the site as intermediate risk with a Risk, Ranking, and Abatement score of I 115 D and additional groundwater monitoring was requested. A comprehensive groundwater sampling event was conducted in August 2020 and the report was submitted to the NCDEQ by Mid-Atlantic on September 25, 2020. The NCDEQ issued the acknowledgement of report receipt on October 23, 2020 requiring an additional groundwater sampling event and the submittal of a Groundwater Monitoring Report by January 22, 2021.NCDEQ sent an acknowledgement of report received to Mid-Atlantic on February 16, 2021.The installation of two additional groundwater monitoring wells was requested at this time in order to further define the contaminant plume and determine groundwater flow direction for the site.This report documents the installation of two groundwater monitoring wells and results of this sampling event.

Approximately one ton of impacted soil was excavated and disposed of at the A&D Environmental (A&D) facility in High Point, North Carolina. Groundwater Monitoring Report Speedway 6993 Fayetteville, North Carolina June 21, 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 NCDEQ, the subject site is located in the Middendorf Formation (Geologic Unit: Km). The site appears to be located in an area of “sand, sandstone, and mudstone, gray to pale gray with an orange cast, mottled; clay balls and iron-cemented concretions common, beds laterally discontinuous, cross bedding common”. The subject site is located in the Coastal Plain physiographic region. In the coastal plain, an aquifer is typically composed of one to several layers of eastward thickening, permeable sands or limestone split by discontinuous, clay-rich materials. Confining units, consisting of clay-rich sediments, exist above and below an aquifer. These confining units are more continuous clay layers and separate the aquifer. The surficial or unconfined aquifer overlies all the confined aquifers in the coastal plain. 2.5 Site Geology and Hydrogeology Selected historical site assessment data is provided in Appendix A. GENERAL GEOLOGIC PROFILE Depth (FT BLS)GEOLOGIC DESCRIPTION 0 - 30 feet (approx.)Natural deposits primarily consist of sands and sandy clayey silts with varying thicknesses. 30 - 40 feet Clays and clayey silty sand. Bedrock not encountered to a depth of 40 feet. HYDROGEOLOGICAL PARAMETERS - PHASE II LIMITED SITE ASSESSMENT REPORT, APRIL 17, 2020 UNLESS OTHERWISE NOTED PARAMETER RESULT Average Depth to Shallow Groundwater, February 2020 25.42 feet Maximum Observed Seasonal Fluctuation in Depth to Groundwater (February to August 2020) Approximately 3.02 feet Groundwater Flow Direction Not calculated - see text for explanation Hydraulic Gradient (Horizontal)Not calculated - see text for explanation Hydraulic Conductivity (measured by rising head testing) Data not available - aquifer testing not performed to date Groundwater Flow Velocity1 Data not available - aquifer testing not performed to date Groundwater Monitoring Report Speedway 6993 Fayetteville, North Carolina June 21, 2021 Page 3 3.0 POTENTIAL RECEPTORS Receptor information for the site was previously documented in Mid-Atlantic’s Phase II Limited Site Assessment Report dated April 17, 2020. 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 exceedance of GCLs for benzene in MW-1. According to the USGS topographic quadrangle map of Cliffdale, North Carolina (Drawing 1.1), the nearest surface water body is Persimmon Creek, located approximately 2,770 feet to the northeast of the source area of the release. 4.0 FIELD ACTIVITIES On April 12, 2021,soil borings for additional groundwater monitoring wells MW-5 and MW-6 were advanced by Geologic Exploration, Inc. under Mid-Atlantic's supervision. The locations for MW-5 and MW-6 were strategically selected to help determine groundwater flow direction for the site.No soil samples were collected from the borings and cuttings were used for screening and lithographic description.The soils were collected and visually classified to characterize soil types and prepare soil boring logs, as presented in Appendix B. Hollow stem augers were utilized to advance the borehole for installation of the groundwater monitoring wells.Shallow, Type II monitoring wells were constructed in the borings for MW-5 and MW-6.The wells were constructed as shown on the well construction records.Upon completion, the newly installed monitoring wells were developed by removing groundwater using new, dedicated, polyethylene bailers.The purpose of the development was to remove the fine particles from the filter pack and to improve the hydraulic connection between the well and the aquifer.Well construction records are also provided in Appendix B.Monitoring well construction information is summarized in Table 4.1 and Mid-Atlantic procedures are provided in Appendix C.Soil cuttings were containerized for disposal at a later date. 4.1 Liquid Level Measurements Mid-Atlantic personnel collected depth to free product and/or depth to groundwater measurements from site monitoring wells on April 13, 2021. Monitoring well construction details are provided in Table 4.1. Liquid level measurements, along with historical measurements, are summarized in Table 4.2. As indicated, none of the wells exhibited free product.Liquid level measurements were collected using the procedures described in Appendix C. Groundwater Monitoring Report Speedway 6993 Fayetteville, North Carolina June 21, 2021 Page 4 4.2 Monitoring Well Sample Collection Mid-Atlantic personnel collected groundwater samples from monitoring wells MW-1, MW-2, MW-3R, MW-4R, MW-5 and MW-6 on April 13, 2021. Groundwater samples were collected using the procedures described in Appendix C. Samples were shipped to Pace Analytical Services (Pace) in Mt. Juliet, Tennessee and analyzed by the methods shown on the chain-of-custody record provided in Appendix D. 5.0 DISCUSSION OF SAMPLING RESULTS 5.1 Summary of Analytical Results A laboratory analytical report and chain-of-custody record for groundwater samples collected on April 13, 2021 are provided in Appendix D, with the results of selected target compounds summarized in Table 5.1. As summarized, the groundwater samples collected from wells MW-1,MW-3R and MW-5 exhibited several contaminant concentrations above the NCGQS. However, only benzene in the sample collected from MW-1 exceeded the GCLs. 5.2 Description of Current Plume Size and Location Free Product On April 13, 2021, Mid-Atlantic measured the depth to water in the monitoring wells using an electronic water level indicator. No evidence of free product was observed in the monitoring wells. Groundwater An isoconcentration map for benzene for the April 13, 2021 groundwater sampling event is provided as Drawing 5.1. The contaminant plume appears to be migrating towards the south/southwest. 5.3 Additional Monitoring Information •Proximity of Plume to Nearest Receptor Based on the results of the LSA receptor survey, three water supply wells were observed within 1,500 feet of the release area during the area reconnaissance. According to the owner of Pro Carwash & Detail located at 648 N. Reilly Road, their onsite water supply well is used for irrigation only and is not used for drinking water. Mid-Atlantic used GIS software to measure the distance from the diesel dispenser to the water supply well and determined that the well is located 264 feet from the source area of the release. The Property is connected to city water. Mid-Atlantic spoke with Mr. Heavner, the property Groundwater Monitoring Report Speedway 6993 Fayetteville, North Carolina June 21, 2021 Page 5 owner of the two water supply wells located at 735 N Reilly Road, and he indicated that the wells are not currently in use and have been out of service for a long time. Both Properties are connected to city water. According to the Fayetteville Public Works Commission (PWC) Water Resources Engineering Department municipal-supply system is available to all the properties within the 1,500-foot radius search area of the search area of the release. The nearest surface water body is Persimmon Creek, located approximately 2,770 feet to the northeast of the source area of the release. •Groundwater Flow Direction After the installation of monitoring wells MW-5 and MW-6,groundwater appears to flow towards the south and southwest and the southeast.Wells MW-1 and MW-2 were set to depths of 22 feet BLS, while MW-3R,MW-4R,MW-5 and MW-6 were set to 40 feet BLS. The depth to water near wells MW-1 and MW-2 is significantly shallower than the depth to water in wells MW-3R,MW-4R MW-5 and MW-6. Mid-Atlantic suspects that MW-1 and MW-2 may be set in a perched aquifer and/or are hydraulically separated from a deeper, surficial aquifer in which the other wells were constructed.If the water table elevations from wells MW-1 and MW-2 are removed from the water contour map, the groundwater flow direction changes and flows predominantly in a northerly direction. This is likely more representative of the true groundwater flow direction in this area. Vertical groundwater flow direction beneath the site has not been determined, since a deeper, Type III well has not been constructed to date. 6.0 FUTURE SITE REMEDIATION Dissolved phase concentrations of the target compound benzene have slightly decreased in the sample collected from monitoring well MW-1, but still exceed the GCL. Mid-Atlantic recommends continued groundwater monitoring events to monitor plume movement and to evaluate whether an active remedial approach may be necessary. If concentrations continue to decrease and are below the GCLs, the site may be eligible for a risk downgrade. If the site can be classified as "low risk," it may be eligible for closure through filing of a Notice of Residual Petroleum with the property deed.The next sampling event should take place in approximately October of 2021. 7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS Based on the results of the April 13, 2021 sampling activities, Mid-Atlantic concludes the following: •Free product was not detected in site monitoring wells; •Groundwater samples collected from wells MW-1, MW-3R and MW-5 exhibited several contaminant concentrations above the NCGQS. However, only benzene in MW-1 was detected at a concentration greater than the GCL; Groundwater Monitoring Report Speedway 6993 Fayetteville, North Carolina June 21, 2021 Page 6 •Groundwater flow direction appears to flow in south, southwest and southeast directions from a possible perched aquifer near wells MW-1 and MW-2. If measurements from these two wells are not considered, groundwater flow appears to be towards the north. Based on the results, Mid-Atlantic recommends the following: •Continued periodic sampling (at least semi-annual) of the monitoring wells to evaluate contaminant plume movement; and, •Submittal of this report to the NCDEQ for their review and comment. 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.June 22, 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.

Raleigh NC 27610 Ph: (919) 250-9918 LOG OF BORING: MW-6 Page: 2 of 2 APPENDIX C MID-ATLANTIC FIELD PROCEDURES Monitoring Well Installation Procedures I. Shallow Type II Monitoring Wells These wells are typically constructed in a borehole made by a power auger and penetrate the top portion of the shallow water table. The wells are typically constructed of two-inch diameter (although they can be larger), Schedule 40 PVC casing with 0.010-inch mechanically slotted well screen placed in the bottom of the well. These wells are constructed such that the well screen intersects the water table at the time of construction. A gravel pack (typically clean washed sand) is used to fill the borehole annular space around the screened interval and is usually terminated one to two feet above the top of the screen. A typically two-foot thick layer of bentonite is then placed in the annular space above the sand pack, and the remainder of the annular space is filled from bottom to top with a Portland cement/bentonite mixture pumped through a tremie pipe. The monitoring wells are equipped with locking caps and fitted with flush-mounted protective manhole covers or above-ground “stick-up” protectors. Note: for site-specific well construction details, refer to Well Construction Records II. Deep Type III Monitoring Wells Deep, Type III monitoring wells are constructed with two “telescoping” casings, an inner casing and an outer casing. The outer casing is larger in diameter (typically six-inch diameter Schedule 40 PVC) and typically extends from land surface to bedrock or a confining unit. The bottom of this casing is typically firmly set into the top of bedrock or other confining layer and then tremie-grouted into the borehole. After the grout has cured, the borehole is then advanced below the bottom of the outer casing by drilling through the outer casing to the desired depth. The inner casing (typically two-inch diameter Schedule 40 PVC) is constructed with a screened interval that monitors water within bedrock fractures or other deeper water-bearing zones. The borehole annulus is then filled with gravel pack, bentonite, and grout and finished at land surface as described above. Note: for site-specific well construction details, refer to Well Construction Records Soil Sampling Procedures I. Sample Collection Direct Push Technology (DPT, or “Geoprobe”) DPT uses a truck-mounted hydraulic rig to push a steel sampling probe into the subsurface to collect soil and/or groundwater samples. The sampling device used to collect the soil samples during this investigation was the “macrocore” sampler. This sampler consists of a four-foot long, two-inch diameter stainless steel spoon containing a clear, acetate liner. When the macrocore sampler is driven into the subsurface, the soil is collected into the acetate liner and then retrieved to the land surface. The liner is then cut open and the soil lithology is characterized and soil samples are collected. Split Spoon Sampling This method of soil sampling is typically used during advancement of hollowstem augers for the construction of monitoring wells. Soil samples are obtained from the borings by driving a prewashed, 1-3/8-inch inner-diameter split-spoon sampler at five foot intervals to termination in general accordance with ASTM D-1586 (Standard Penetration Test) specifications. Blow counts for each six inches of split-spoon penetration are recorded during advancement of the spoon. Samples are then retrieved to the land surface, the split-spoon is opened, and the soil lithology is characterized and soil samples are collected. Hand Augering This method is typically used for shallow sampling in areas where access is limited or underground obstacles such as utilities may be present. A pre-washed, three-inch diameter steel auger bucket is attached to extension rods and manually turned to penetrate the subsurface to the desired sampling depth. Samples are then retrieved to the land surface and the soil lithology is characterized and soil samples are collected directly from the hand auger bucket. Excavator Bucket Sampling This method is typically used during UST excavation and soil excavation projects. The soil samples are collected from the excavator bucket when it is not safe to collect the samples by other means. Care is taken when collecting samples from the bucket to avoid soil that has come in contact with the bucket itself to avoid cross contamination. II. Headspace Field Screening A portion of each sample is removed from the sampling device and placed in a pre- labeled, plastic "ziploc" bag. After several minutes, the gas contained in the "headspace" or void area within the bag is tested with a photoionization detection (PID) and/or Flame Ionization Detector (FID). These are useful as scanning devices to detect the presence of volatile organic compounds (VOCs) but are not relied upon to determine specific levels of contamination. Typically, the samples exhibiting the highest headspace readings will be submitted to the laboratory for analysis. III. Preparation for Laboratory Analysis The sample collector dons new nitrile sampling gloves prior to handling each sample. The samples are placed into laboratory-prepared, pre-labeled, sampling containers, packed in ice, and shipped to a certified laboratory under chain-of-custody control. The sampler places an executed custody seal on the cooler prior to leaving the sampler’s custody. Laboratory analyses to be performed on the samples, along with other sampling information, are specified on the chain-of-custody, which is placed in the cooler with the samples. Groundwater Sampling Procedures I. Sample Collection A. 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.

Therefore, not all TICs are identified and quantitated using individual standards. TIC listings are prepared utilizing a computerized library search routine of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist. Quantitation is accomplished by relative peak area of the TIC compared to that of the nearest internal standard from the total ion chromatogram. TICs are identified and quantitated only if the peak area is 10% or more of that of the nearest internal standard. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic -

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. RT Retention Time. 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. N The analyte is tentatively identified and the associated numerical value may not be consistent with the actual concentration present in the sample. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R3243.01B L1338610 04/29/21 19:57 38 of 45 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R3243.01B L1338610 04/30/21 08:27 38 of 45 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 R3243.01B L1338610 04/29/21 19:57 39 of 45 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Mid-Atlantic - Speedway NC R3243.01B L1338610 04/30/21 08:27 39 of 45 Page 1 of 3 TURN AROUND TIME STANDARD Chain-of-Custody-Record Speedway Project Information Speedway Store #: C210006993 Facility ID 0000015515 Address:670 N Reilly Rd City:Fayetteville State:NC Phone #:Fax #: Speedway Proj.
