The release was reported during UST removal activities at the Circle K 2708383 facility located at 873 Old Charlotte Road SW in Concord, North Carolina (Site). A topographic map illustrating the Site vicinity is included as Figure 1. As required, this report incorporates the elements of a UST Closure Report and Post - Excavation Soil Contamination Assessment Report. In May of 2019 three 10,000-gallon petroleum USTs and associated piping and dispensers were removed from the site by Zebra Environmental and Industrial Services, Inc. (Zebra) with activity monitoring and assessment provided by Crawford Environmental Services of North Carolina, PLLC (CES) personnel. A discussion of procedures used during the UST closure activities is provided in subsequent sections of this report. Upon removal of the UST system, petroleum contaminated soil was discovered. Over excavation efforts were performed to remove grossly contaminated soils from the Site. The Site is currently vacant under lease by Circle K Stores, Inc. (Circle K). The removal of the former UST system was prompted by permanent closure of the Site facility by Circle K. Page No. 1 CES@NCa 2.0 Site History and Characterization Initial Abatement Action Report Circle K 2708383 Concord, North Carolina The site has operated a UST system since at least 1987. Historical UST owner/operator and other responsible party information is provided in Table 1. As required, the following provides information relevant to site history and characterization. 2.1 General Information Facility Name: Circle K No. 2708383 Facility ID Number: 4527 Facility Address: 873 Old Charlotte Road Southwest Concord, North Carolina 28027 Cabarrus County 2.2 Project Contacts UST Owner: Property Owner: UST Removal Contractor: Environmental Consultant Analyzing Laboratory 1 Analyzing Laboratory 2: Circle K Stores, Inc. 2550 West Tyvola Road, Suite 800 Charlotte, North Carolina 28217 (704) 583-5762 Hickory Woods, Inc.

PO Box 357 High Point, North Carolina 27261 (336) 841-5276 CES 301 McCullough Drive, Suite 400 Charlotte, North Carolina 28262 (704) 909-2911 Pace Analytical Services, LLC 9800 Kincey Avenue, Suite 100 Huntersville, NC 28078 (704) 875-9092 NC Certification Number: 12 Rapid Environmental Diagnostics, LLC 5598 Marvin K. Moss Lane, Suite 2003 Wilmington, North Carolina 28409 (844) 384-7815 NC Certification Number: N/A Page No. 2 CES@NCa 2.3 UST Information Initial Abatement Action Report Circle K 2708383 Concord, North Carolina The former UST system included three single -wall fiberglass tanks containing various grades of gasoline, two dispenser islands, and associated fiberglass piping. The three USTs were oriented in a northeast -southwest direction located on the perimeter of the property in the vicinity of the southwestern property corner as illustrated on Figure 2. Product piping exited the central northeast side of the UST pit and supplied product to two double -sided dispensers. UST system and other release information is summarized in Table 2. No ASTs were present on the site. 2.4 Past Releases In January and February of 2004, a due diligence investigation involving collection of soil and groundwater samples at the Site was conducted in response to the sale of Circle K by ConocoPhillips to Alimentation Couche-Tard. Results of the investigation determined that soil and groundwater at the Site was impacted with petroleum hydrocarbons. As a result of the due diligence investigation, the North Carolina Department of Environment and Natural Resources (now known as the North Carolina Department of Environmental Quality [NCDEQ]) assigned Incident Number 27671 under responsible party ConocoPhillips and issued a Notice of Regulatory Requirements (NORR) requesting the completion of a Site Check at the facility. On March 23, 2004, a Site Check was completed at the facility by advancing eleven soil borings in the vicinity of the UST system based on previous soil boring locations and site check requirements. Results of the site check indicated that releases may have occurred from the eastern -most UST and from the dispensers. On April 29, 2004, a NORR requesting the preparation of a Limited Site Assessment (LSA) was issued by the NCDEQ. Results of the LSA were documented in a report dated September 15, 2004 prepared by ATC Associates of North Carolina, P.C. (ATC). Based on the findings of the report, the incident was classified as "low" risk and no further action was requested. On June 12, 2006, the NCDEQ issued a "Notice of No Further Action". Incident Number 27671 received closure through recordation of a "Notice of Residual Petroleum" (NRP) with the Cabarrus County Register of Deeds perpetually restricting groundwater at the site from use as a water supply. The notice was signed by ConocoPhillips and recorded in Deed Book 6870, Page 168 on July 11, 2006. No other information was obtained or reviewed for the completion of this report. 2.5 Current Facility Status At the time of this assessment the facility was vacant and permanently closed. According to Circle K, the UST system was last used on May 8, 2019. During the May 2019 assessment activities, improvements observed onsite included a one-story convenience Page No. 3 CES@NC.. Initial Abatement Action Report Circle K 2708383 Concord, North Carolina store building and the associated paved parking areas. Pertinent site features are illustrated on Figure 2. 2.6 Subject Site and Surrounding Property Use The Site facility formerly operated as Circle K 2708383, a convenience store with Shell branded petroleum retail. The Site was utilized for commercial purposes with adjacent properties to the northwest and southwest also utilized as commercial properties. Adjacent properties to the northeast and southeast were utilized for residential purposes. Municipal water is supplied to the Site and vicinity by the City of Concord. Surface cover at the site consists primarily with asphalt. Portions of the pavement which were removed to access the UST system were resurfaced with concrete. Sparse vegetation is present along the perimeter of the Site. 2.7 Regional Geology and Site Hydrogeology According to the 1985 "Geologic Map of North Carolina", the site is located within the Charlotte Belt of the Inner Piedmont Physiographic Province. This area is characterized by intrusive igneous rocks identified as metamorphosed quartz diorite described as foliated to massive. The general vicinity also contains metamorphic rocks identified as biotite gneiss and schist. The metamorphic rocks are described as interangular and megacrystic with abundant potassic feldspar and garnet interlayered and gradational with calc-silicate rock, sill imanite-mica schist, mica schist, and amphibolite. Rocks of the Syenite of Concord Plutonic Suite and Gabbro of Concord Plutonic Suite have also been identified in the area. The primary soil type observed during UST closure activities was sandy silt with lean clay. Weathered rock was encountered at depths ranging from 13 to 16-feet BGS. Groundwater was not encountered during excavation activities which reached a maximum depth of approximately 16-feet below ground surface (BGS). Based on previous site assessment, depth to groundwater at the site ranges from approximately 18 to 20-feet below ground surface (BGS). Groundwater flow direction, as determined by historical assessments, was to the east-southeast and generally appears to follow the dip of rock observed in the tank pit. Page No. 4 CES@NCa 3.0 UST Closure Assessment Initial Abatement Action Report Circle K 2708383 Concord, North Carolina In conducting UST removal and assessment activities at the site, the most recent revision of the NCDEQ "Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases" dated February 1, 2019 was utilized for guidance. The following offers further details and provides required information pertaining to the UST removal activities conducted at the Site. 3.1 Preparations for Closure A "Notice of Intent: UST Permanent Closure or Change -In -Service" form (UST-3) was completed and submitted to the NCDEQ on April 18, 2019 (refer to Appendix A for a copy of the UST-3 Form). Prior to removal of the UST system, the existing canopy at the site was demolished beginning May 20, 2019. UST removal and demolition permits were acquired from the City of Concord and Cabarrus County, as applicable, by the UST removal contractor. Prior to demolition of the fuel dispenser canopy structure, an asbestos containing materials survey was also performed. 3.2 UST Cleaning and Residual Fluids Disposal On May 21, 2019, the USTs and piping were cleaned and evacuated by Zebra utilizing a pressure washer and vacuum truck in tandem. A total of approximately 595-gallons of a product/water mixture, consisting primarily of rinsate, was removed from the USTs. Refer to Appendix B for copies of the disposal manifest. The storage, sampling and disposal of residual fluids recovered/generated during the UST closure activities were conducted by Zebra at their High Point, NC facility. In addition, subsequent to cleaning and prior to removal, the atmosphere within the USTs was verified inert through the use of an explosive limit meter under direct supervision of a representative of the City of Concord Fire Department. 3.3 UST System Removal and Disposal Product dispensers were removed from the two (2) dispenser islands at the Site through the course of canopy demolition procedures commencing on May 21, 2019. On May 21, 2019, the dispenser sumps and product piping were exposed for visual assessment. The sumps and piping were observed to be in good condition. Product piping was constructed of a fiberglass reinforced plastic (FRP). Following inspection, the product piping was removed from the ground. USTs were exposed for inspection on May 22, 2019 and appeared to be in good condition. Following inspection, the USTs were removed from the ground on May 22, 2019 by Zebra. The cleaned, evacuated, and inert fiberglass USTs were mechanically crushed by Zebra prior to removal from the excavation. The crushed tank and product piping material was loaded and transported off -site by Zebra. Certification of tank disposal by Zebra is included in Appendix B. Photographic documentation of the removal is included in Appendix C. A copy of the "Site Investigation Report for Permanent Closure or Change -in -Service of Registered UST' form (UST-2A) is included as required in Appendix D. Page No. 5 CES@NCa 3.4 Soil Sampling Locations and Collection Procedures Initial Abatement Action Report Circle K 2708383 Concord, North Carolina Soil samples were collected as required from directly beneath the former UST system components concurrent with removal of the system. The number of soil samples collected was based on the specific dimensions of the UST system, as applicable. Soil sample collection was conducted as follows: • One sample per 10-linear feet under each UST (12 samples); • One sample beneath each dispenser (2 samples); • One sample per 10-linear feet under product lines and every joint (5 samples) The locations of UST closure soil samples collected from the site is illustrated on Figure 3. Soil samples collected for UST closure assessment were submitted to the Rapid Environmental Diagnostics, LLC (RED Lab) on -site representative for analysis by "Typing" UVF. The UVF laboratory report is included in Appendix E. 3.5 Groundwater and Surface Water Sampling Procedures Groundwater was not encountered in the excavation and no surface water bodies were observed within 1,500-feet of the site; therefore, no groundwater or surface water samples were collected during UST closure activities conducted as part of this assessment. 3.6 Quality Control Measures Sample handling procedures consisted of placing soil samples into sterilized, laboratory - provided containers. Each sample was labeled with a unique specific identification number using an indelible marker including at a minimum the collection date and time and then transported and submitted to the laboratory for analysis under chain -of -custody protocol. As previously discussed, no field sampling equipment (hand -auger, split -spoon sampler, etc.) was utilized to collect soil samples; therefore, no decontamination procedures were necessary to complete soil sampling. All soil samples collected were taken directly from the bucket of earth excavating equipment utilizing new disposable nitrile gloves during each sample collection to reduce the overall risk of cross contamination. Care was taken to collect soil samples not in direct contact with the excavation equipment Soil samples were collected on May 22, 2019 and were subsequently logged into the laboratory on the same day. All samples were received by the laboratory within method specified holding times and temperatures (<6°C). No duplicates or trip blanks were utilized for this assessment. A copy of the chain -of -custody form(s) is located in Appendix E. 3.7 Analytical Methods Used Soil samples collected beneath the former UST system were analyzed on -site by RED Lab using UVF Typing reporting Gasoline Range Organics (GRO), Diesel Range Organics (DRO), and total benzene, toluene, ethylbenzene, and xylenes (collectively referred to as "BTEX"). Page No. 6 CES@NCa 3.8 Site Sensitivity Evaluation Initial Abatement Action Report Circle K 2708383 Concord, North Carolina The site vicinity appears to be serviced by municipal water supply. No suspect water supply wells, basements, or surface water bodies were observed within a 1,500-foot radius of the site. Several underground utilities were observed on and adjacent to the site as shown on Figure 2. According to the USGS Topographical Map (Figure 1), an intermittent stream is located approximately 1,200-feet northeast of the site. An additional intermittent stream is located approximately 1,500-feet south of the site. Both of these intermittent streams form upper tributaries of Irish Buffalo Creek which is located approximately 5,000-feet northeast of the site. Page No. 7 C �� a Initial Abatement Action Report Circle K 2708383 Concord, North Carolina 4.0 Soil Excavation & Assessment CES referred to the NCDEQ "Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases" dated February 1, 2019 for guidance in completing initial response and abatement activities. Due to a confirmed release via soil analytical data from the UST closure sampling, initial abatement actions commenced including submission of a "24-Hour Release and UST Leak Reporting Form" (UST-61) to the NCDEQ Mooresville Regional Office on May 23, 2019 via email correspondence. A copy of the UST-61 form is included as Appendix F. The amount and exact cause of the release are unknown. As requested by the NCDEQ Incident Manager Trudy Beverly in email correspondence dated May 29, 2019, a "20-Day Report" was completed and submitted to the NCDEQ on June 10, 2019. This IAA report incorporates the 20-day requirements previously submitted. The following offers further details and provides required information pertaining to the initial abatement actions conducted at the Site. 4.1 Excavation Extent Determination Following removal of the UST system, soils were visually inspected for staining or other signs of petroleum contamination. Free product was not observed. During the removal of the UST system, no materials located beyond 5-feet of the UST system components were removed. Required UST closure samples were collected directly from the open excavation at the locations illustrated on Figure 3 and analyzed on -site by UVF analysis performed by RED Lab. A photo -ionization detector (PID) calibrated to 1 00-parts-per-mill ion (ppm) Isobutylene was also utilized in the field to directly screen soils in an effort to help determine the overall extent of impact and guide any necessary soil excavation/sampling activities. As part of CES standard operating procedures, field screening equipment is calibrated according to the manufacturer's specification prior to each use and recorded in a dedicated calibration log included with the unit. Soils within the excavation were also visually assessed for the presence of staining. Soil samples were placed into sealable Zip-loc° bags after preserving the required volume in laboratory provided bottle -ware, as applicable. The bagged sample was allowed time to equilibrate and volatilize at ambient air temperature of at least 68-degrees Fahrenheit at which point the headspace was screened for the presence of volatile organic vapors utilizing the PID. 4.2 Extent of Soil Excavation Activities Based on the results of UVF analysis, soils at the locations of SS-6, SS-8, SS-11, SS-1 3, and SS-16 (Figure 3) were impacted above the NCDEQ Action Limits for GRO and/or DRO of 50-milligrams per kilogram (mg/kg) and 100-mg/kg, respectively. Over excavation commenced via spot digging at the locations of GRO and DRO exceedances focusing in the vertical direction and presumed downgradient locations. Page No. 8 CES@NCn Initial Abatement Action Report Circle K 2708383 Concord, North Carolina Rock was encountered in the excavation at depths ranging from 13 to 16-feet BGS which prevented additional vertical soil excavation where encountered. Depth to rock appeared to be shallowest at 13-feet BGS on the northwestern side of the UST pit and dipped towards the southeastern side of the UST pit to a depth of approximately 16-feet BGS. Excavation base soil samples were collected directly above the soil/rock interface. Groundwater was not encountered in the excavation; therefore, groundwater samples were not collected. Sidewall samples were collected and screened to determine the lateral extent of contamination and direct additional required excavation. Over excavation sample locations and the final limits of excavation are illustrated on Figure 4. A summary of UST closure samples and analytical data is provided in Table 3. Following completion of over excavation activities, extent sidewall and base samples were collected and submitted to Pace Analytical Services, LLC (Pace) for traditional laboratory analysis for volatile organic compounds by EPA Method 8260 and volatile petroleum hydrocarbons by MADEP VPH. On -site UVF analytical results and PID screening indicated that sidewalls were not impacted, therefore lateral excavation was not performed. 4.3 Quantity of Soils Removed, Storage Methods, and Final Disposition During tank removal, a total of approximately 200-cubic yards (yd3) of overburden pea gravel and 100 yd3 of over burden soil was generated. The overburden material was initially stockpiled, analyzed via UVF, determined to be clean, and subsequently returned to the tank basin to be used as backfill material. Results of the stockpile samples are included in Table 3 and Appendix E. Soils generated during over -excavation efforts were loaded directly into trucks, manifested, and transported off -site for disposal at the AES facility located in Thomasville, NC. Soil samples were collected from the waste stream for disposal characterization purposes and submitted to RED Lab for UVF screening at regular intervals. Approximately 130-tons of petroleum impacted soil were removed from the site. Certified disposal manifests are included in Appendix B. 4.4 Soil Analytical Results After review of the laboratory analytical report for over -excavation soil samples, the following detections in excess of regulatory limits were reported: • Sidewall NE (Northeast sidewall of the UST pit) o Benzene was reported at a concentration of 0.043 milligrams per kilogram (mg/kg) which is in excess of the NCDEQ Soil -to -Groundwater Maximum Soil Contaminant Concentration (STW MSCC) of 0.0056 mg/kg; • Base (Deepest point of base of UST pit on top of rock) o Aliphatics C5-C8 was reported at a concentration of 205 mg/kg which is in excess of the NCDEQ STW MSCC of 68 mg/kg; o Aliphatics C9-C12 was reported at a concentration of 789 mg/kg which is in excess of the NCDEQ STW MSCC of 540 mg/kg; Page No. 9 CES@NCa Initial Abatement Action Report Circle K 2708383 Concord, North Carolina • L Base (Base of lines over -excavation on top of rock) o Ethylbenzene was reported at a concentration of 9.1 mg/kg which is in excess of the NCDEQ STW MSCC of 4.9 ug/kg; o Xylenes were reported at a concentration of 21.7 mg/kg which is in excess of the NCDEQ STW MSCC of 4.6 mg/kg; o Naphthalene was reported at a concentration of 16.2 mg/kg which is in excess of the NCDEQ STW MSCC of 0.16 mg/kg o Aliphatics C5-C8 was reported at a concentration of 393 mg/kg which is in excess of the NCDEQ STW MSCC of 68 mg/kg; o Aliphatics C9-C12 was reported at a concentration of 1,550 mg/kg which is in excess of both the NCDEQ STW MSCC and Residential Soil Cleanup Levels MSCC of 540 mg/kg and 1,500 mg/kg, respectively. Additionally, laboratory reporting limits exceeded the NCDEQ STW MSCCs in soil samples Sidewall NW, Base, and L Base for Benzene and/or other constituents. Remaining soil samples were found to be either below NCDEQ regulatory limits or below the laboratory reporting limit. A summary of the over -excavation analytical data is provided in Table 4 and illustrated on Figure 5. A copy of the laboratory report is included in Appendix E. 4.5 Groundwater Analytical Results No groundwater was encountered during the assessment activities completed by CES at this site during May of 2019.

Also send a copy to the Central Office in Raleigh. i o # Date Received SEE MAP ON THE BACK OF THIS FORM FOR THE CENTRAL AND REGIONAL OFFICE ADDRESSES. INSTRUCTIONS (READ THIS FIRST) Complete and return at least thirty (30) days prior to closure or change -in-service activities. If a Professional Engineer (P.E.) or a Licensed Geologist (L.G.) provides supervision for closure or change -in-service site assessment activities and signs and seals all closure reports then at least a five (5) working days notice is acceptable. Completed UST closure or change -in-service site assessment reports, along with a copy of the UST-2 form, should be submitted to the appropriate Division of Waste Management (DWM) Regional Office within thirty (30) days following closure activities. The UST-2 form should also be submitted to the Central Office in Raleigh so that the status of the tanks may be changed to permanently closed and your tank fee account can be closed out. Note: Tank fees may be due on unregistered tanks. UST closure and change -in-service site assessments must be completed in accordance with the latest version of the Guidelines for Site Checks, Tank Closure and Initial Response. The guidelines can be obtained at http://www.wastenotnc.org/. Note: To close tanks in place you must obtain prior approval from the DWM Regional office located in the region where the facility is located. You must make sure that USTs removed from your property are disposed of properly. When choosing a closure contractor, ask where the tank(s) will be taken for disposal. Usually, USTs are cleaned and cut up for scrap metal. This is dangerous work and must be performed by a qualified company. Tanks disposed of illegally in fields or other dumpsites can leak petroleum products and sludge into the environment. If your tanks are disposed of improperly, you could be held responsible for the cleanup of any environmental damage that occurs. I. OWNERSHIP OF TANKS II.

Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above the shear valve) Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that connects the submersible turbine pump to the tank Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.) Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor recovery lines, and fill lines) Unknown: identifies releases for which the source has not been determined Definitions of Causes Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser) Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser) Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken components, and components that have changed dimension) Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust) Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells) Unknown: use when the cause has not been determined '",q Body Shopwe .0ad outhwes `yRps kv •r � 6 oo le •S: .,tit,.
