Summary of Activities Associated with Current TA WithersRavenel, Inc. (WR) conducted a groundwater sampling event at the former Whitaker’s Service Station site in Mooresboro, Cleveland County, North Carolina in association with task authorization (TA) TA-01 under North Carolina Department of Environmental Quality (NCDEQ) Contract #N70522-C. The scope of work for this project included the gauging, purging, and sampling of existing monitoring wells MW-1, MW-2, and MW-3, and water supply well SW-E Blanton. A field blank was also analyzed as a part of this TA. 2. Soil, Groundwater and LNAPL Assessment Information Soils No soil samples were collected by WR in association with this task authorization. Laboratory results for soil samples obtained at the time of underground storage tank (UST) closures in June 1994 showed gasoline range organic (GRO) and/or diesel range organic (DRO) total petroleum hydrocarbon (TPH) in several samples at concentrations exceeding the regulatory limits in place at the time of closures. TPH GRO was detected at 2,562 milligrams per kilogram (mg/kg) at approximately two to three feet beneath the former 1,000-gallon gasoline UST of basin #3 which contained one 1,000-gallon gasoline UST and one 2,000-gallon gasoline UST. Data for soil samples collected in association with completion of a Limited Site Assessment (LSA) at the location showed several compounds at concentrations exceeding Soil to Groundwater Maximum Soil Contaminant Concentrations (MSCCs) in soil samples collected from soil borings for monitoring wells MW-1 and MW-2. No petroleum constituents were detected above Soil to Groundwater MSCCS in soil samples collected from monitoring well MW-3. Groundwater WR collected groundwater samples from site monitoring wells MW-1, MW-2, and MW-3 and water supply well SW-E. Blanton on March 24, 2023. The groundwater samples were submitted for laboratory analysis of VOCs by SM6200B. A field blank was also submitted for analysis of VOCs by SM6200B. • Laboratory analytical results indicated that benzene and naphthalene exceeded the 15A NCAC 2L Groundwater Quality Standards (2L Standards) in monitoring well MW-2. • Laboratory analytical results indicated that monitoring well MW-1 contained acetone above the method detection limits but below the 2L Standards. • MTBE was reported at a concentration below the 2L Standard in water supply well SW-E. Blanton. • Analytical data for monitoring well MW-3 and the field blank did not report any compounds above the method detection limits. WithersRavenel Our People. Your Success.

Brief Description of Site Characteristics The property is located in a rural, residential / agricultural area of Mooresboro, Cleveland County, North Carolina (Figure 2). The property is currently vacant, and the USTs and dispensers have been removed. 4. Information on Receptors/Potential Receptors According to historical information, there are five active water supply wells within 1,000-feet of the subject property. Potable water is supplied to the local area by the Cleveland County Water Department. The estimated locations of these water supply wells are shown on Figure 5. Information regarding the water supply sources is provided on Table B-5A. 5. Regional and Site Geology and Hydrology According to the 1985 USGS Geologic Map of the State of North Carolina, the subject property is located within the Inner Piedmont, Chauga Belt, Smith River Allochthon, and Sauratown Mountain Belt. The site bedrock is intrusive rocks consisting of garnet, staurolite, kyanite, or sillimanite occur locally; lenses and layers of quartz schist, micaceous quartzite, calc-silicate rock, biotite gneiss, amphibolite, and phyllite. The soils encountered in this area are the residual product of in-place chemical weathering of rock presently underlying the site and/or historic depositional events. According to the USDA Soil Survey Map, the soils at the site consists of the Pacolet-Bethlehem complex (PbB2). The PbB2 is found on 2 to 8 percent slopes and consists of sandy clay loams that originated from weathered granite and gneiss and/or schist. Surficial unconfined groundwater movement within the overlying soils is controlled largely by topographic gradients. However, as the groundwater percolates downward, it becomes influenced by the subsurface geologic conditions. Therefore, the direction of groundwater movement in the deeper aquifers may not be consistent with the reflecting topography. Recharge occurs primarily by infiltration along higher elevations and typically discharges into streams or other surface water bodies as the water flows from higher topographic elevations to lower topographic elevations.

GROUNDWATER SAMPLING – MARCH 2023 On March 24, 2023, WR personnel mobilized to the subject property to perform groundwater sampling activities at the facility in association with TA-01 under NCDEQ Contract # N70522-C. The scope of work for this project included the gauging, purging, and sampling of existing monitoring wells MW-1, MW-2, and MW-3. WR was also tasked with collecting a water supply well sample from SW-E. Blanton. The groundwater samples collected under TA-01 were submitted for laboratory analysis of VOCs by SM6200B. The following paragraphs describe the sampling activities and associated laboratory analytical results. Groundwater Sampling Activities Prior to the purging and sampling of the site monitoring wells on March 24, 2023, WR personnel opened and gauged those wells targeted for purging and sampling with an electronic water level indicator to determine the depth to groundwater at each well location. The depth to groundwater measurements in the monitoring wells ranged from 10.40 feet (ft) below the top of casing (ft-BTOC) in monitoring well MW-3 to 11.68 ft-BTOC in monitoring well MW-1. The depth to water in each of the wells was above the screened interval. Based on data obtained during this sampling event, groundwater elevations were the same in all three monitoring wells. Historically, groundwater flow was toward the south to southeast. A groundwater hydraulic gradient map based on the March 24, 2023, measurements are shown on Figure 3. Groundwater elevation data are included in Table B-7. Following gauging, monitoring wells were purged and sampled with separate, disposable polyethylene 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 via courier under chain-of-custody procedures to Waypoint Analytical, Inc. (Waypoint) in Charlotte, NC for testing by SM6200B. Laboratory Results Analytical results for the groundwater samples collected on March 2023, indicated that monitoring well MW-2 contains 2L Standards exceedances of benzene and naphthalene. Laboratory analytical results indicated that monitoring well MW-1 contains acetone above the method detection limits but below the 2L Standards. Laboratory analytical results indicated that water supply well SW-E. Blanton contains MTBE above the method detection limits but below the 2L Standards. There is no established USEPA MCL for MTBE at this time. Analytical data for monitoring well MW-3 and the field blank did not report any compounds above the method detection limits.

Blanton sampling location APPENDIX C 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.

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. WithersRavenel Our People. Your Success.
