Save More #045 – Incident #15046 WR Project # 02172214.24 Annual Monitoring Report July 2021 3 SECTION B. EXECUTIVE SUMMARY 1. Summary of Activities Associated with Current TA WithersRavenel, Inc. (WR) conducted a receptor survey and groundwater sampling event at the Save More #045 site located at 1424 N. Fayetteville Street in Asheboro, Randolph County, North Carolina in association with TA‐01 under NCDEQ Contract #N122019B. The scope of work for this project included conducting a receptor survey and sampling the monitoring wells associated with the site. 2. Soil, Groundwater and LNAPL Assessment Information Soils No soil samples were obtained in association with the monitoring activities conducted by WR during the June 2021 event. In April 2003, Engineering Consulting Services, Inc. (ECS) supervised the removal of two 6,000‐gallon and one 8,000‐gallon gasoline USTs from the site. Tank closure soil sampling indicated petroleum contaminants in excess of the Soil‐to‐Groundwater Maximum Soil Contaminant Concentrations (MSCCs), but below the Industrial/Commercial MSCCs. Groundwater WR collected groundwater samples from site monitoring wells MW‐1, MW‐3 through MW‐8, and VEW‐1 on June 8, 2021. The collected groundwater samples were submitted for laboratory analysis of VOCs by SM6200B plus oxygenates. Analytical results for the groundwater samples collected on June 8, 2021, revealed the following:  Monitoring wells MW‐1, MW‐3, and MW‐7 contained benzene above the GCLs.  Monitoring wells MW‐1 and MW‐7 contained MTBE above the GCLs.  Monitoring wells MW‐1, MW‐3, MW‐7, and VEW‐1 contained several petroleum compounds above the 2L Standards.  Tert‐Amyl Methyl Ether (TAME) was detected above the 2L Standards in monitoring wells MW‐1, MW‐3, MW‐7, and VEW‐1. Light Non‐Aqueous Phase Liquid Light non‐aqueous phase liquid (LNAPL) was detected in monitoring well MW‐1 in January 2015 at a thickness of 0.10 feet. 3. Receptor Information As part of TA‐01, WR performed a receptor survey which revealed the following:  No evidence of water supply wells was identified by WR within 1,000 feet of the source area.  WR inquired with the City of Asheboro Utility Department to obtain information regarding the connection status of the properties within 1,000 ft of the site. The occupied parcels within 1,000 feet of the source area are connected to the municipal water supply.  Although subsurface utilities were identified in the site vicinity, the shallowest observed depth to water at the site is approximately 20 feet below ground surface. Therefore, these utilities are not expected to be conduits for contamination.  No additional receptors (streams or wetlands) were identified within 500‐ft of the source area. WithersRavenel Our People. Your Success. Save More #045 – Incident #15046 WR Project # 02172214.24 Annual Monitoring Report July 2021 4  The site was not determined to be in a Wellhead Protection (WHP) area. 4. Remediation Activities Based on WR’s review of historical files available for the site, the following remedial activities have been completed at the location:  Absorbent booms were installed in monitoring well MW‐1 in May 2015.  An Aggressive Fluid Vapor Recovery (AFVR) event was conducted using monitoring well MW‐ 1 in January 2019 and recovered approximately 226 gallons of petroleum‐impacted groundwater. Based on currently available information, WR is unaware of additional remedial actions that have been performed at the site. 5. Recommendations Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  WR recommends performing an AFVR event combined with air sparging utilizing monitoring wells MW‐1, MW‐3, MW‐7, and VEW‐1 to reduce contaminant concentrations at the site.  Installation of a monitoring well to the southeast of the source area on the adjacent parcel to the south across Rainbow Drive.  Annual sampling of the site monitoring wells. SECTION C. SITE HISTORY AND CHARACTERIZATION The following information summarizes the site history and characterization. 1. UST Information Two 6,000‐gallon gasoline USTs and one 8,000‐gallon gasoline UST and associated product lines and dispensers were removed from the site in April 2003 during site renovations. These USTs were registered as JP Asheboro, Facility ID 00‐0‐0000018414. Current USTs at the site include one 20,000‐gallon compartmentalized UST (14,000‐gallon gasoline and 6,000‐gallon gasoline UST) and one 4,000‐gallon kerosene UST. No documentation of over‐excavation was identified during the file review. Figure 1 depicts the site location on the Asheboro, NC USGS Topographic Map. Figure 2 shows the location of the historical UST system. Historical and current UST information is provided in Table B‐1. Photographs of site conditions observed during the June 2021 sampling event are included in Appendix A. 2. Description of Release/General Assessment History The following summary of the assessment history is based on WR’s review of historical files for the subject incident: WithersRavenel Our People. Your Success. Save More #045 – Incident #15046 WR Project # 02172214.24 Annual Monitoring Report July 2021 5 According to the December 17, 2019 Groundwater Monitoring Report prepared by ECS, gasoline was discovered in the pit of one of the USTs located onsite on November 16, 1995. According to the Report of Initial Response, Abatement Measures, Site Check and Initial Site Characterization, submitted by LAW Engineering and Environmental Services, Inc. on January 19, 1996, approximately 126 gallons of gasoline and impacted water were removed from the “pump pit” and the UST pump was replaced. In January 1996, soil samples were collected around the UST system. The soil sample collected from soil boring SB‐1 at a depth of approximately 13.5 to 15 feet below ground surface (ft bgs) exhibited Total Petroleum Hydrocarbons Gasoline Range Organics (TPH‐ GRO) at a concentration of 2,000 milligrams per kilograms (mg/kg). The remaining soil samples collected either contained concentrations of TPH‐GRO less that than the current NCDEQ Action Level of 100 mg/kg or were not detected above the laboratory method reporting limit. In 1998, a Phase I Limited Site Assessment (LSA) was performed at the site. Soil borings were advanced, and a receptor survey was conducted. Laboratory analysis of the soil samples collected indicated p‐isopropyltoluene and naphthalene at concentrations greater than the Soil‐to‐ Groundwater Maximum Soil Contaminant Concentrations (MSCCs), but less than the Residential MSCCs. The receptor survey indicated that there were no water supply wells within 1,500 feet of the site. No groundwater samples were collected during this Phase I LSA. According to the Phase I LSA report, fractured bedrock was encountered at depths ranging from 10 to 15 ft bgs. In April 2003, the former UST system (two 6,000‐gallon gasoline USTs, one 8,000‐gallon gasoline UST, product lines, and dispensers) was removed from the site due to renovations. Soil samples were collected during UST removal and soil analytical results indicated petroleum hydrocarbons at concentrations greater than the Soil‐to‐Groundwater MSCCs, but below the residential MSCCs. Replacement USTs including one 20,000‐gallon compartmentalized gasoline UST and one 4,000‐ gallon kerosene UST were installed on the site. No soil was removed from the site during the UST closure activities. ECS submitted a Report of Limited Site Assessments – Phases I and II on December 18, 2003. Monitoring wells MW‐1 through MW‐6 and VEW‐1 were installed at the site and sampled. Multiple targeted constituents were detected in the groundwater samples at concentrations greater than their respective North Carolina 2L Groundwater Quality Standards (NC2LGWQS) and Gross Contamination Levels (GCLs). An updated receptor survey indicated that there were no water supply wells within 1,500 feet of the site. On June 16, 2004, ECS submitted a Report of Comprehensive Site Assessment (CSA) – Petroleum‐ Impacted Soils. During the CSA a total of twenty soil borings were advanced to collect soil samples. Soil analytical results indicated petroleum hydrocarbons at concentrations greater than the Soil‐to‐Groundwater MSCCs, but less than the Residential MSCC. Groundwater sampling events were performed in March 2009, January 2015, May 2016, July 2018, and October 2019. Multiple targeted constituents were detected in the groundwater samples at concentrations greater than the NC2LGWQS and GCLs. Reportedly, 0.10 feet of liquid non‐aqueous phase liquids (LNAPL) was measured in monitoring well MW‐1 during the sampling event in January 2015. In May 2015, ATC supervised the installation of monitoring well MW‐7 in order to delineate the groundwater impacted above the GCLs; however, concentrations in MW‐7 exceeded the GCL. In February 2016, ATC supervised the installation of monitoring well MW‐8 located off‐site across Rainbow Drive. This well has not shown concentrations exceeding the laboratory reporting limits with the exception of acetone detected during one sampling event. WithersRavenel Our People. Your Success. Save More #045 – Incident #15046 WR Project # 02172214.24 Annual Monitoring Report July 2021 6 On January 8, 2019, ECS conducted an AFVR event at the site, utilizing monitoring well MW‐1 as an extraction point. Approximately 226 gallons of liquid was removed during the AFVR event. In addition, Zebra calculated approximately 0.0001 gallons of volatile organic vapors were removed during the AFVR event. 3. Brief Description of Site Characteristics The property is located in a commercial and residential area of Asheboro, Randolph County, North Carolina (Figure 1). The property is currently occupied by the Save More gas station (see Figure 2). The Randolph County Geographic Information System (GIS) website identifies the subject property as parcel identification number 7762022630 and is approximately 0.82 acres. 4. Information on Receptors/Potential Receptors During the June 2021 receptor survey, no evidence of water supply wells was identified by WR. Although subsurface utilities were identified in the site vicinity, the shallowest observed depth to water at the site is approximately 20 feet below ground surface. Therefore, these utilities are not expected to be conduits for contamination. No additional receptors (streams or wetlands) were identified within 1,000‐ft of the source area. 5. Regional and Site Geology and Hydrology The Geologic Map of North Carolina depicts the site in the as being in the Carolina Slate Belt of the Piedmont Physiographic Province. The site underlain by the Uwharrie Formation which consists of light gray to greenish gray metamorphosed dacitic to rhyolitic flows and tuffs, interbedded with mafic and intermediate metavolcanic rock, metargillite, and metamudstone of the Cambrian to Late Proterozoic. According to the United States Department of Agricultural (USDA) Natural Resources Conservation Service (NRCS) Web Soil Survey, the source area is underlain by Georgeville‐Urban land complex (2 to 10 percent slopes). The Georgeville‐Urban land complex is well drained, found on summits and shoulders, and the parent material is residuum weathered from metavolcanics and/or argillite. Silty clay was encountered to depths ranging from 1 to 10 feet bgs, underlain by silty sand, followed by silt. According to the Phase I LSA report, fractured bedrock was encountered at depths ranging from 10 to 15 ft bgs. SECTION D. RECEPTOR SURVEY On June 8, 2021, WR personnel mobilized to the subject site to perform a site reconnaissance and receptor survey in association with the current TA. Activities included those more thoroughly described below: 1 Site Reconnaissance The site is currently an active gas station located at the northeast corner of North Fayetteville Street and Rainbow Drive inside the corporate limits of Asheboro, Randolph County. The site is located in a residential and commercial area. The adjacent property to the north is a vacant WithersRavenel Our People. Your Success. Save More #045 – Incident #15046 WR Project # 02172214.24 Annual Monitoring Report July 2021 7 residence. The adjacent property to the south across Rainbow Drive is a shopping center. Carter Bank & Trust is located across North Fayetteville Street to the west. A vacant wooded parcel is east‐adjacent to the site. The site is shown on Figure 2, including site features, structures and the locations of the former and current UST systems included in Table B‐1. The site and adjoining parcels are depicted on Figure 3, and adjacent property information included in Table B‐5C. The site is zoned by the City of Asheboro as “General Commercial” (B‐2), “is intended to serve the convenience goods, shoppers’ goods, retail, and service needs of the motoring public, both local and transient”. WR examined the U.S. Geological Survey 7.5‐minute series topographic map for the site (Figure 1) and the surface contours for the location indicate the site has an approximate elevation of 800‐ ft above mean sea level (AMSL), in a hilly area. As determined using the June 2021 water table elevations, groundwater flow through the site is to the south and southeast. 2 Receptor Survey As part of TA‐01, WR performed a receptor survey:  No evidence of water supply wells was identified by WR within 1,000 feet of the source area.  WR inquired with the City of Asheboro Utility Department to obtain information regarding the connection status of the properties within 1,000 ft of the site. The occupied parcels within 1,000 feet of the source area are connected to the municipal water supply.  Although subsurface utilities were identified in the site vicinity, the shallowest observed depth to water at the site is approximately 20 feet below ground surface. Therefore, these utilities are not expected to be conduits for contamination.  No additional receptors (streams or wetlands) were identified within 500‐ft of the source area. An unnamed tributary of Hasketts Creek was identified approximately 600 feet west of the site.  The site was not determined to be in a WHP area. Returned water supply well forms are included in Appendix B. Information regarding municipal water connections from the City of Asheboro Utilities Department (buffered parcels within 1,000 ft of the Save More #045 site) is also included in Appendix B. SECTION E. GROUNDWATER SAMPLING – JUNE 2021 On June 8, 2021, WR personnel mobilized to the subject property to perform limited groundwater sampling activities at the facility in association with TA‐01 under NCDEQ Contract # N122019B. The scope of work for this project included gauging, purging, and sampling of monitoring wells MW‐1 through MW‐8 and VEW‐1. In the performance of assessment activities at the site, WR was able to gauge and sample monitoring wells MW‐1, MW‐3 through MW‐8, and VEW‐1. Monitoring well MW‐2 has been destroyed. WithersRavenel Our People. Your Success. Save More #045 – Incident #15046 WR Project # 02172214.24 Annual Monitoring Report July 2021 8 The following paragraphs describe the sampling activities and associated laboratory analytical results. Groundwater Sampling Activities Prior to the purging and sampling of site monitoring wells as described below, WR personnel gauged the wells with an electronic oil‐water interface meter to determine the depth to groundwater at each well location. During the performance of these activities, LNAPL was not identified in the site monitoring wells. The depth to groundwater measurements in the monitoring wells across the site ranged from 17.51 feet below the top of casing (ft‐BTOC) in monitoring well MW‐6 to 20.42 ft‐BTOC in monitoring well MW‐8. Based on groundwater elevation measurements on June 8, 2021, the direction of groundwater flow is generally towards the south and southeast. Groundwater flow as determined based on these measurements is shown on Figure 5. Groundwater elevation measurements for this event are presented in Table B‐7. Following gauging, the monitoring wells were purged and sampled with separate, disposable polyethylene (PE) bailers for each well. Samples from the wells were decanted into pre‐preserved laboratory provided sample containers. Samples collected from site monitoring wells were submitted to Waypoint for testing by Standard Method (SM) 6200B plus oxygenates. Laboratory Results Analytical results for the groundwater samples collected on June 8, 2021, revealed the following:  Monitoring wells MW‐1, MW‐3, and MW‐7 contained benzene above the GCLs.  Monitoring wells MW‐1 and MW‐7 contained MTBE above the GCLs.  Monitoring wells MW‐1, MW‐3, MW‐7, and VEW‐1 contained several petroleum compounds above the 2L Standards.  Tert‐Amyl Methyl Ether (TAME) was detected above the 2L Standards in monitoring wells MW‐1, MW‐3, MW‐7, and VEW‐1. These results are shown on Figure 6 and included in Table B‐4. Copies of the laboratory analytical report and chain‐of‐custody are included in Appendix C. WR’s generalized standard operating procedures are provided in Appendix D. SECTION F. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA‐01, which included conducting a receptor survey and sampling the monitoring wells associated with the site. Conclusions based on observations, analytical data and research relating to the release at the site combined with historical information include the following:  The site is currently operating as the Save More gas station and three USTs (two gasoline and one kerosene) are in use at the site.  Municipal water is available to the site and surrounding area. Water supply wells were not identified within 1,000 feet of the site.  Monitoring wells MW‐1, MW‐3 through MW‐8, and VEW‐1 were located, gauged, and sampled. Monitoring well MW‐2 has been destroyed.  LNAPL was not identified in the gauged monitoring wells. WithersRavenel Our People. Your Success.

APPENDIX D GENERAL STANDARD OPERATING PROCEDURES Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using an electronic oil/water interface probe. The interface probe has both an audible and illuminating light that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination or field personnel exposure to contaminants. Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device. Screening of samples with a PID, FID or other field screening device is performed in accordance with device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a dedicated, disposable bailer, a peristaltic pump or submersible electric pump. When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging. When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre-preserved container(s) provided by the laboratory. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is contained in laboratory grade sample containers as described in the previous section. Water quality parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or electric submersible pump. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon the method(s) of sampling performed at any site, but will generally include the following: • Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary, • Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),  Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry, • Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary prior to their use in sampling.
