Summary of Activities Associated with Current TA WithersRavenel, Inc. (WR) conducted a groundwater sampling event at the Former RB’s Package Store site located at 714 N. George Street in Goldsboro, Wayne County, North Carolina in association with Task Authorization (TA) TA‐01 under North Carolina Department of Environmental Quality (NCDEQ) Contract # N70522‐C. 2. Soil, Groundwater and LNAPL Assessment Information Soils No soil samples were obtained by WR in association with this task authorization; however, based on historical reports, three confirmation samples collected from the tank basin were found to contain total petroleum hydrocarbons (TPH) at concentrations ranging from 18.2 parts per million (ppm) to 3,430 ppm. Groundwater One or more compounds were reported in samples from each of the wells collected during June 2023 (MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐6, MW‐7, MW‐10, MW‐11 and MW‐12). One or more compounds were reported at concentrations exceeding their NC 2L Standards in samples from wells MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐7, MW‐ 10, MW‐11 and MW‐12. Benzene was reported in the samples obtained from MW‐3 and MW‐ 3 at concentrations exceeding the GCL for the compound. While exceedances to the GCL for benzene persist within MW‐3 and MW‐3R, based on current data the contaminant plume appears relatively stable. Light Non‐Aqueous Phase Liquid (LNAPL). No LNAPL was found within any wells measured during June 2023. During the November 2022 groundwater sampling event, groundwater monitoring well MW‐3 contained 0.20 feet of LNAPL and MW‐11 contained 0.01 feet of LNAPL. Prior to November 2022, LNAPL had been indicated in MW‐3R on several occasions, and in MW‐3 on December 16, 2009. 3. Receptor Information WR did not perform a receptor update in association with the current task authorization for the site. A receptor survey was conducted by WR as a part of a Limited Site Assessment (LSA) in 2004. According to the receptor survey, no water supply wells were identified within 1,000 feet of the release. The subject site and surrounding properties are supplied with municipal water by the Wayne County Water District #7. Regionally, overland flow drains towards an un‐named surface water body located approximately 1,800 feet west of the site, and ultimately to the Little River. WithersRavenel Our People. Your Success. Former RB’s Package Store – NCDEQ Inc.# 20283 WR Project # 23‐0307‐DU Monitoring Report August 2023 4 4. Remediation Activities During the UST closure activities, approximately 38 tons of soil was excavated and disposed of offsite. In addition, three MMPE events were conducted at the site in January, June, and October 2011. During the January 2011, contaminated groundwater was recovered from MW‐ 3R and MW‐7, while in June and October 2011, contaminated groundwater was recovered from MW‐1, MW‐3R, and MW‐11. During these MMPE events, approximately 5,109 gal (January 2011), 10,793 gal (June 2011), and 10,134 gal (October 2011) of dissolved petroleum liquid was recovered. No LNAPL was observed following the MMPE events in 2011. Additional MMPE events were conducted in November 2021 and in October 2022 as LNAPL was present in site monitoring wells MW‐3 and MW‐3R. During the November 2021 MMPE event, contaminated groundwater and LNAPL was recovered from MW‐3. During the October 2022 MMPE event, LNAPL was recovered from MW‐3 and MW‐3R. During these event, approximately 6,587 gal (November 2021) and 7,436 gal (October 2022) of dissolved petroleum liquid was recovered. No LNAPL was observed following the MMPE completion of the events, however LNAPL had returned after each event. No LNAPL was found within any wells measured during June 2023. Based on currently available information, no additional remedial actions 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:  Consideration of a surfactant‐enhanced injection in the vicinity of monitoring wells MW‐3 and MW‐3R in conjunction with LNAPL and groundwater recovery.  Continued sampling of on‐site and off‐site monitoring wells associated with this release.

SITE HISTORY AND CHARACTERIZATION WR has completed a groundwater sampling event for the referenced site in association with TA‐ 01 at the facility. The following information summarizes the site history and characterization. 1. UST Information In August 2001, one 4,000‐gallon tank was abandoned in place due to proximity to power pole and electrical lines. Remaining 4,000‐gallon UST is suspected to be in the right‐of‐way as road has been widened twice since gas station had operated. The general location of the site is depicted on Figure 1 and the approximate former location(s) of the UST systems are depicted on Figure 2. The site currently operates as an auto repair shop. WR is not aware of any aboveground storage tanks (ASTs) located on the subject site. Table B‐1 includes information regarding the USTs formerly located on the property. 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:  The USTs were previously owned and operated by Richard Branch. A NORR was issued by the NCDEQ because of a release discovered on site. In July 1999, NCDEQ learned that Mr. Branch was deceased. A well was placed on site during the investigation of the LUST site, identified as the Former Conoco Store #33025 – (NCDEQ Incident #11821), located adjacent and north of the subject site. LNAPL was previously observed in groundwater in this monitoring well.  In August 2001, WR supervised field activities which included the abandonment of one 4,000‐gallon tank in place due to proximity to power pole and electrical lines.

Benzene was reported in the sample obtained from MW‐3R at a concentration exceeding the GCL for the compound. 3. Brief Description of Site Characteristics The property is located in a residential and commercial area of Goldsboro, Wayne County, North Carolina (Figure 1). The property includes a single‐story commercial building of block construction (Figure 2). The building on site is surrounded by concrete and asphalt pavement and areas of grass and dirt. The Wayne County parcel identification number for the property is 2599991460. The Wayne County Tax Department indicates that the property is currently owned by Bartolon Anastacio Deleon and was purchased in February 2020. Examination of the U.S. Geological Survey 7.5‐minute series topographic map of Goldsboro, North Carolina indicates the site is located approximately 35 feet above mean sea level (Figure 1). Data collected from the groundwater monitoring well system indicates the groundwater table ranges between 9.65 feet and 11.32 feet below land surface (BLS) and flows generally to the south southeast. It should be noted that MW‐3, MW‐10, and MW‐11 were not used to construct groundwater contours. Groundwater analytical data collected from monitoring wells associated with the Former RB’s Package Store site indicates the plume has migrated offsite. WithersRavenel Our People. Your Success. Former RB’s Package Store – NCDEQ Inc.# 20283 WR Project # 23‐0307‐DU Monitoring Report August 2023 8 4. Information on Receptors/Potential Receptors WR did not perform a receptor update in association with the current task authorization for the site. A receptor survey was completed by WR as a part of a LSA completed in 2004. According to the receptor survey, no water supply wells were identified within 1,000 feet of the release. The subject site and surrounding properties are supplied with municipal water by Wayne County Water District #7. Regionally, overland flow drains towards an un‐named surface water body located approximately 1,800 feet west of the site, and ultimately to the Little River, within the Neuse River drainage Basin of the state. 5. Regional and Site Geology and Hydrology The Geologic Map of North Carolina depicts the site is located in the cretaceous soils of the Black Creek Formation of the Coastal Plain Physiographic Province. The Black Creek Formation is characterized as “clay, gray to black, lignitic, contains thin beds and laminae of fine‐grained micaceous sand and thick lenses of cross‐bedded sand, glauconitic, fossiliferous clayey sand lenses in upper part.” According to the United States Department of Agricultural (USDA) Natural Resources Conservation Service (NRCS) Web Soil Survey, the source area is underlain by Norfolk loamy sand (0 to 2 percent slopes). These soils are described as being loamy sand and sandy clay loams derived from loamy marine deposits. The soils are typically located in convex, linear lenses in flats on marine terraces and broad interstream divides on marine terraces. These soils are well drained. WithersRavenel Our People.

GROUNDWATER SAMPLING – JUNE 2023 On June 21, 2023, WR personnel mobilized to the subject property to conduct groundwater sampling of monitoring wells located at the RB’s Package Store site. The following paragraphs describe the monitoring well installation and sampling activities, as well as the 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 LNAPL (if present) and groundwater within well locations. No LNAPL was found within any wells measured during June 2023. The depth to groundwater measurements in the Type II monitoring wells across the site ranged from 8.80 feet below the top of casing (ft‐BTOC) in monitoring well MW‐6 to 10.70 ft‐BTOC in monitoring well MW‐12. Based on groundwater elevation measurements obtained on June 21, 2023, the direction of groundwater flow is generally towards the south southeast, however, the water table at the location appears relatively flat. The depths‐to‐groundwater were within the screened interval for all wells. Groundwater flow as determined based on these measurements is shown on Figure 3. Current and historical groundwater elevation measurements for this event are presented in Tables B‐7 and B‐9. Field notes are included in Appendix A. Following gauging, the monitoring wells were purged and sampled using 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 Analytical for testing by Standard Method (SM) 6200B. Laboratory Results Analytical results for groundwater samples obtained from site monitoring wells in June 2023 indicated the following:  One or more compounds were reported in samples from each of the wells (MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐6, MW‐7, MW‐10, MW‐11 and MW‐12).  One or more compounds were reported at concentrations exceeding their NC 2L Standards in samples from wells MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐7, MW‐10, MW‐11 and MW‐12.  Benzene was reported in the samples obtained from MW‐3 and MW‐3 at concentrations exceeding the GCL for the compound. Groundwater analytical results are summarized in Table B‐4 and shown on Figure 4. A dissolved benzene isoconcentration map is included as Figure 5. Copies of the laboratory analytical report and chain‐of‐custody are included in Appendix B. WR’s generalized standard operating procedures are provided in Appendix C. WithersRavenel Our People. Your Success. Former RB’s Package Store – NCDEQ Inc.# 20283 WR Project # 23‐0307‐DU Monitoring Report August 2023 10 SECTION E. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA‐01 which included the gauging, purging, and sampling of monitoring wells MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐6, MW‐7, MW‐10, MW‐11 and MW‐12. Conclusions based on observations, analytical data and research relating to the release at the site combined with historical information include the following:  The property is currently occupied and utilized as vehicle repair shop.  The site is located within the cretaceous soils of the Black Creek Formation of the Coastal Plain Physiographic Province.  The subject property and surrounding property have access to municipal water. Water supply wells within 1,000 feet and surface water bodies within 500 feet of the site have not been identified. Therefore, the removal of LNAPL and depletion of contaminants to levels beneath GCL concentrations are the remedial goals for the site.  One or more compounds were reported in samples from each of the wells (MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐6, MW‐7, MW‐10, MW‐11 and MW‐12).  One or more compounds were reported at concentrations exceeding their NC 2L Standards in samples from wells MW‐1, MW‐2, MW‐3, MW‐3R, MW‐4R, MW‐5, MW‐7, MW‐10, MW‐11 and MW‐12.  Benzene was reported in the samples obtained from MW‐3 and MW‐3 at concentrations exceeding the GCL for the compound.  Although GCL exceedances for benzene persist in MW‐3 and MW‐3R, the contaminant plume appears to be relatively stable.  The contaminant plume appears to extend from near the former pump island location on the northern side of the structure on the site to the south and southeast. WR estimated the western lateral extent of the plume to lie beneath the paved surface of George Street. Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  Consideration of a surfactant‐enhanced injection in the vicinity of monitoring wells MW‐3 and MW‐3R in conjunction with LNAPL and groundwater recovery.  Continued sampling of on‐site and off‐site monitoring wells associated with this release.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated.

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.
