This report satisfies the requirements specified in the Underground Storage Tank Section Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement, Change 9 (February 1, 2019). One UST, used for storing home heating oil, was previously removed from the subject property. On June 30, 2020, a total of 69.23 tons of impacted soil were excavated and transported to a permitted facility for bioremediation as an initial abatement measure. The laboratory results for four soil samples collected from just above the soil -bedrock interface at the limits of the excavation showed that no petroleum residuals exceeding applicable standards remain in the unexcavated soils. Bedrock was encountered during initial abatement activities. The environmental impact to the underlying groundwater has not yet been determined. For this reason, the approval of a Notice of Residual Petroleum (NRP) (groundwater land use restriction only) will be required prior to issuance of a Conditional Notice of No Further Action (NFA) letter unless groundwater sampling indicates no environmental impact. In such case, Cedar Rock will request issuance of a final NFA letter. If you have any questions or need additional information, please give me a call. Sincerely, PO - Robert A. Payne, L.G.

A former 550-gallon underground storage tank (UST), identified as T1, was located approximately as shown in Figure 2. On June 25, 2020, Cedar Rock performed an inspection of the soils beneath the former UST location which confirmed the presence of significant soil contamination. According to the Cabarrus County tax office records, the building was constructed in 1963. Table 1 lists pertinent storage tank system ownership information. Table 2 lists specific UST information for T1. The subject site is surrounded by residential properties. City water is available to properties in the area. 2.0 INITIAL RESPONSE AND ABATEMENT ACTIVITIES Initial abatement activities consisted of excavating 69.23 tons of obviously contaminated soil from the source area of the release on June 30, 2020. Soil removal continued to a maximum depth of 10.5 feet. The lateral dimensions of the excavation pit measured about 14.0 feet by 12.5 feet at the pit floor. The excavated contaminated soil was transported to a permitted disposal facility located in Thomasville, North Carolina for bioremediation. No free product was encountered during the initial abatement activities. There are no other subsurface structures other than bedrock on the subject site where free product or vapors could accumulate or that would provide a migration pathway for the release. The possibility of an explosion or the threat to public health and safety or to the environment from the accumulation of vapors does not appear to be of concern at this time. Therefore, the release is unlikely to be a significant fire/safety/health hazard. The 24-Hour Release Report and UST Leak Reporting Form (UST-61) was submitted to the North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), UST Section in Mooresville on June 30, 2020. 3.0 EXCAVATION OF CONTAMINATED SOIL 3.1 Field Activities Soil excavation activities were performed on June 30, 2020 (see photographs in Appendix A). Petroleum -impacted soils were encountered in the source area at a depth of about 5.0 feet below land surface (bls). As impacted soil was removed from the source area, the soils were periodically inspected by a North Carolina licensed geologist for evidence of petroleum residuals (staining and odors). Soil removal continued to a maximum depth of 10.5 feet where bedrock was encountered. The lateral dimensions of the excavation pit measured about 14.0 feet by 12.5 feet at the pit floor (see Figure 3). Groundwater was not encountered during excavation activities. A total of 69.23 tons of contaminated soil were transported to a permitted disposal facility located in Thomasville, North Carolina for bioremediation. Copies of the soil disposal manifests are included in Appendix B. 3.2 Soils Investigation According to the Geologic Map of North Carolina (1985), the subject site is underlain by granitic rock. The native soils in the source area of the release consisted of a brownish orange, micaceous, sandy SILT. A copy of the excavation log for the excavation is included in Appendix C. On June 30, 2020, Cedar Rock collected five soil samples to document the effectiveness of soil excavation. One soil sample, CR-1, was collected from a depth of 6.0 feet bls beneath the center of the estimated former location of T1. Four soil samples, CR-2 through CR-5, were collected from just above the soil -bedrock interface at the limits of the excavation. Sample locations are shown in Figure 3. The soil samples were collected according to the sampling procedures included in Appendix D. Soil samples CR-1 through CR-5 were submitted to the laboratory for Total Petroleum Hydrocarbons (TPH) analyses by EPA Methods 3550 and 5030. TPH were quantified in soil sample CR-1 at a concentration of 40,900 parts per million (ppm) by EPA Method 3550 and at a concentration of 1,470 ppm by EPA Method 5030. TPH were quantified by EPA Method 3550 at a concentration of 21.6 ppm in sample CR-3, and a concentration of 18.3 ppm in sample CR-5. No TPH were quantified in soil samples CR-2 and CR-4 by EPA Method 3550, or in samples CR-2 through CR-5 by EPA Method 5030. Soil sampling activities and results are summarized in Table 3. A copy of the laboratory report and chain -of -custody is included in Appendix E. 3.3 Discussion of Results Figure 3 shows a plan view of the source area, limits of the excavation, and soil sample locations in relation to the former location of the UST. Petroleum -impacted soils were encountered in the source area at a depth of about 5.0 feet bls. Soil removal continued to a maximum depth of 10.5 feet where bedrock was encountered. The lateral dimensions of the excavation pit measured about 14.0 feet by 12.5 feet at the pit floor. Four soil samples were collected from just above the soil -bedrock interface at the limits of the excavation. As shown in Table 3, no petroleum constituents exceeding applicable standards were quantified in these soil samples. 4.0 CONCLUSIONS AND RECOMMENDATIONS One UST, used for storing home heating oil, was removed from the subject property on June 30, 2020. A total of 69.23 tons of impacted soil were excavated and transported to a permitted facility 2 for bioremediation as an initial abatement measure. The laboratory results for four soil samples collected from just above the soil -bedrock interface at the limits of the excavation showed that no petroleum residuals exceeding applicable standards remain in the unexcavated soils. Bedrock was encountered during initial abatement activities. The environmental impact to the underlying groundwater has not yet been determined. For this reason, the approval of a Notice of Residual Petroleum (NRP) (groundwater land use restriction only) will be required prior to issuance of a Conditional Notice of No Further Action (NFA) letter unless groundwater sampling indicates no environmental impact. In such case, Cedar Rock will request issuance of a final NFA letter. 5.0 REFERENCES 24-Hour Release Report and UST Leak Reporting Form (UST-61); submitted to the North Carolina Department of Environmental Quality, Division of Waste Management, UST Section, Mooresville Regional Office on June 30, 2020.

APPENDIX D Sampling & Decontamination Procedures CEDAR ROCK ENVIRONMENTAL, P.C. EQUIPMENT DECONTAMINATION PROCEDURES Every effort will be made to prevent cross -contamination of soil and groundwater samples before, during, and after sample collection. It is company policy that drillers contracted by Cedar Rock decontaminate their drilling and sampling equipment with steam prior to, and after, each use and/or each boring. The following procedures apply to the decontamination of field equipment used by Cedar Rock employees. Soil Sampling Equipment Stainless steel hand augers, spoons, and knives will be cleaned prior to, and after, each use and/or each boring. If hand auger advancement of a borehole through contaminated soil is obvious or suspected, a clean auger bucket will be used to retrieve the sample portion. A fresh pair of disposable vinyl gloves will be worn while handling the sample container. Sampling equipment will be decontaminated by washing with phosphate -free soapy water; rinsing in tap water followed by an isopropyl alcohol rinse; and a final "triple" rinse with distilled water. The equipment will then be allowed to air dry. Clean sampling spoons and knives will be stored in a fresh ziplock bag. If available, steam may be used instead of the above procedure. Groundwater Sampling quipment Use of groundwater level measuring devices will proceed from the wells known to be the least contaminated to those known to be more contaminated. If it is not known how contaminated the wells are, measurements will be taken on the up gradient wells prior to the down gradient wells. A fresh pair of disposable vinyl gloves will be worn at each well during water level and sample collection. Water level measuring and well sampling (i.e., pumps and lines) devices will be decontaminated between wells by washing the wetted portion of the device as described above. Each well will be sampled with a new disposable or decontaminated, dedicated bailer during each sampling event. New nylon or cotton string will be used during each sampling event on each bailer. If the bailer contains a significant quantity of silt or sand after purging the well of stagnant water, the bailer may be flushed with distilled water. The bailer will never come into contact with anything other than a gloved hand or the inside of the well casing. While allowing the well to recover, the bailer will be hung inside the well at the top of the casing. The string will be coiled and placed in a ziplock bag or vinyl glove such that it does not come into contact with other objects. Groundwater sample containers will be wiped dry and stored in individual ziplock bags. CEDAR ROCK ENVIRONMENTAL, P.C. SOIL SAMPLING PROCEDURES (Collection and Handling) Soil sampling will be performed by, or under, the direct supervision of a North Carolina licensed geologist. Care will be taken to minimize the loss of contaminants from the sample during sample collection, storage, and transport through disturbance of the internal structure of the soil and exposure to heat, sunlight, and air. Decontamination and handling procedures will be used that minimize the chance of cross -contamination of the samples during and after sample collection. All tools used to retrieve, divide, and collect the sample portion (e.g., hand augers, split -barrel sampler, stainless steel spoons, etc.) will be decontaminated prior to and after each use (between samples). See Decontamination Procedures. Vinyl disposable gloves will be worn during sample collection. Gloves will be changed as necessary after handling the sampling equipment (i.e., after breaking open split -barrels) to avoid cross -contamination. Contact between the gloved hand and the soil will be minimized by dividing and collecting the sample portion using a stainless steel spoon or knife. The sample portion will be collected from the core of the soil at the end of the sampling device where the deepest retrieved soil is represented (e.g., hand auger teeth). If the sample is being retrieved using the backhoe bucket, the sample portion will be collected from the consolidated material located directly behind one of the bucket teeth. A separate sampling implement will be used to scrape away foreign material if present and/or the soil which came into contact with the sample retrieving device in order to expose the core of the sample portion to be collected. Immediately upon removal from the ground, the sample will be placed in a laboratory -provided, decontaminated container. The sample container will be precooled, if possible, to minimize loss of volatiles. The sample portion will be disturbed as little as possible during placement into the container. The container will be filled leaving no head -space and immediately capped and sealed. Immediately upon collection, the exterior of the sample container will be wiped free of soil, if necessary, and placed in a ziplock bag to minimize cross -contamination. The sample will immediately be placed in a cooler of ice for storage and transport to the analytical laboratory. The sample will be labeled with sample identification number, project number, date and time of collection, and analyses to be conducted. The sample will be transported as soon as practical to a North Carolina certified laboratory under chain -of -custody.
