Bridge Street, Jonesville, NC EXECUTIVE SUMMARY Terraquest Environmental Consultants, P.C. has completed a CAP Feasibility Study for the release incident at the Jonesville Amoco-B facility located in Jonesville, Yadkin County, North Carolina. This work is related to a release from a previous petroleum UST system. The NCDWM-UST requested the work that included pilot testing, calculations, and considerations of active remedial methods. In consideration of the contamination present and treatment methods investigated, Terraquest recommends DPE for the Jonesville Amoco B release incident. This method proved practical during pilot testing. Terraquest roughly estimates that 3-4 years of operating a DPE remediation system followed by a year of monitored natural attenuation could allow closure of this site in 2028 at a cost of $704,000. While previously denied, Terraquest asks that the NCDWM-UST consider the addition of several air sparge points to the remedial plan to speed efforts along and reduce costs. If the NCDWM-UST agrees, the next step is to generate a CAP Corrective Action Design Report. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 1 428 N. Bridge Street, Jonesville, NC 1.0 INTRODUCTION On behalf of the responsible party, Beroth Oil Company, Inc., Terraquest Environmental Consultants, P.C. is reporting results of a Corrective Action Feasibility Study for the release incident at the Jonesville Amoco-B facility located in Jonesville, Yadkin County, North Carolina. This work was requested by the NCDWM-UST and costs were pre-approved on ePATA 12188- 034. The site location and surrounding cultural features are depicted in Figure 1. The site vicinity is depicted in Figure 2. The site layout and monitoring well network are depicted in Figure 3. Technical methods and standard procedure generally used by Terraquest personnel are outlined in Appendix A and a chronological history of site events is provided in Appendix B. 2.0 UPDATE OF SITE HISTORY AND SOURCE CHARACTERIZATION Two release incidents are documented at this site and were previously combined into one site called Jonesville Amoco-B. 1. UST Owner Information The owner of the previous USTs was Beroth Oil Company. 2. UST Tank Information According to previous reports submitted by others, the UST system consisted of four USTs (two 1,000-gallon gasoline, one 1,000-gallon kerosene, and one 1,000-gallon fuel oil) associated with the former Jonesville Amoco and six USTs (three 10,000-gallon gasoline, two 10,000-gallon fuel oil, and one 10,000-gallon kerosene) associated with the Beroth bulk storage facility. All USTs CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 2 428 N. Bridge Street, Jonesville, NC have been closed by removal. UST system information is provided in Table 1. The former UST locations are depicted in Figure 3. 3. Non-UST Information No non-UST release incident is documented at this site. The Jonesville Amoco facility also operated three ASTs for use as heating oil storage. One of the ASTs was taken out of service in 1988. A second AST was taken out of service after 1988 and a third AST remains at the site. AST system information is provided in Table 1. The AST locations are depicted in Figure 3. 4. Release Description In 1990, two 1,000-gallon gasoline USTs (T1 and T2) were removed from the Jonesville Amoco facility. Soil samples collected from beneath the tanks indicated no detections of petroleum contamination. The location of these tanks is indicated on Figure 3. In December 1993, one 1,000-gallon fuel oil (T3) and one 1,000-gallon kerosene (T4) USTs were removed from the Jonesville Amoco facility. Analytical results for soil samples collected from beneath the USTs indicated the presence of gasoline contamination. Due to the detected contamination, monitoring well MW1 was installed to investigate groundwater quality in the vicinity of the former USTs. Analytical results for samples collected from the monitoring well indicated soil and groundwater had been impacted by a release of gasoline. In March of 1994, three 10,000-gallon gasoline USTs were removed from the bulk facility located on the adjacent property behind Jonesville Amoco. Soil samples collected during the removal of the UST system revealed the presence of petroleum contamination in excess of the TPH action limit. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 3 428 N. Bridge Street, Jonesville, NC No discrete release event has been documented for the USTs or ASTs at the site and the exact quantity of petroleum released to the subsurface is unknown. 5. Site Characteristics All known USTs have been removed from the site that has fluctuated rental tenants over the last few years. The surrounding area includes businesses along Bridge Street that is a main road with residential properties located to the south and west. A shopping plaza is located behind the store to the northeast. An aerial view of the site and surrounding area is provided: The subject property is located northwest of the intersection of North Bridge Street and Plaza Street. The subject property is zoned B-2, business land use. According to the Town of Jonesville SI CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 4 428 N. Bridge Street, Jonesville, NC Planning Department, surrounding properties are a mixture of general business (B-2), manufacturing (M-1), and medium density residential (R-12) land uses. The nearest residence is approximately 290 feet to the west of the site. Property zoning classifications for the surrounding area are detailed on Figure 2. 6. Regional and Site Geology and Hydrogeology The subject property is located in the Sauratown Mountains and Anticlinorium of the Inner Piedmont Belt of the Piedmont Physiographic Region of North Carolina. Generally, gently rolling, well rounded hills and long low ridges are found throughout the Piedmont Physiographic Region. Groundwater in the region is directed toward the Yadkin River to the north. According to the Geologic Map of North Carolina (Brown, 1985), the area is underlain by metagraywacke, amphibolite, and kyanite schist. The following lithologies were encountered at the site during the various stages of assessment: 0’- 6' BGL Silt (ML) Mostly soft to medium stiff tan/orange silt, with few clay. 6’- 18' BGL Clayey Silt (ML) Mostly medium stiff tan/reddish-orange clayey silt. 18’- 44' BGL Saprolite Weathered bedrock with characteristics of overlying regolith soils. 44’- 61' BGL Bedrock The lithogies are presented in the following cross-sectional views: CAP Feasibility Report Beroth Oil Company, Inc.

By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 8 428 N. Bridge Street, Jonesville, NC The topography in the site vicinity consists of rolling hills. Topographic elevations within 1,000 feet of the site range from approximately 880 feet to 1,000 feet above mean sea level. Generally, the slope is lower at the Yadkin River to the north and increases to the south past the site. Local topography is depicted in Figure 1. The Yadkin River is the dominant surface water body in the vicinity of the site. Cobb, Beaverdam, Jonesville, Sanderberry, and Fall Creeks are all located on the south side of the Yadkin River where they discharge. In the site’s vicinity, Elkin, Dutchman, and Turkey Creeks arrive at the River from the north. Surface water features are displayed on Figure 1 and on the following taken from http://data.nconemap.gov/geoportal/dataexplorer/index.jsp: SI CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 9 428 N. Bridge Street, Jonesville, NC The area overlaying the release area is generally covered with gravel and broken asphalt. Surrounding properties are mostly covered in concrete and asphalt. Precipitation which falls on the site will likely travel to storm drains located along Bridge Street. Historical groundwater flow at the site decreases to the north, northwest toward Yadkin River. The water table fluctuates with historical average shallow aquifer mins and max depth to water measurements ranging 15 to 33 feet BGL. The most recent groundwater flow map is provided as Figure 4. Historical groundwater elevation data is provided in Appendix C. 7. Surrounding Property Owners and Occupants Surrounding property owner information is provided in Table 2. 8. Critical Receptors The Town of Jonesville supplies water to all properties located within 1,500 feet of the site. No active potable wells are known to exist within 1,000 feet of the site. Identified wells that have been abandoned are listed on Table 3. 9. Summary of CAP Implementation Terraquest submitted a CAP on April 1, 2013 that was found to be unacceptable due to the high cost of the proposed actions. Terraquest had proposed that the method of soil remediation be excavation where available and SVE of inaccessible areas; groundwater remediation would be accomplished through air sparging whose vapors will be recovered near the road and building via SVE. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 10 428 N. Bridge Street, Jonesville, NC Based on the requests of the NCDWM-UST Incident Manager, Terraquest revised the proposed corrective action following review of the June 2013 groundwater sampling event data. The revision was described in the July 2013-dated Groundwater Monitoring Report: “Terraquest recommends conducting a small excavation as shown on Figure 8 along with free product and GCL removal via MMPE. Historically, MMPE has proven effective at this site. Terraquest also recommends re-visiting air sparging as laid out on Figure 8 if MMPE events do not prove effective at moving the site toward closure. An additional monitoring well is proposed at the location shown on Figure 8. As previously discussed with the NCDWM-UST, should free product appear in locations where it is currently absent, additional remedial wells and or action may be required. Also, the semi- volatile contaminants at the rear of the property may take a long time to naturally attenuate.“ The proposed sparge points and excavation of Figure 8 from the July 2013-dated Groundwater Monitoring Report shows the following: CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 11 428 N. Bridge Street, Jonesville, NC As listed in Appendix B, an excavation and multiple MMPE events have been performed in agreement with the approved corrective actions. However, a sparge system was never installed. The NCDWM-UST did not wish to install a permanent, active system due to the cost. As listed in Appendix B, beginning with Terraquest’s request for a clear path forward in April 2017, there has been many phone calls and emails with the NCDWM-UST without a clear direction forward. In an August 12, 2020 Site Status Report, included in Appendix B, Terraquest answered the following questions posed by the NCDWM-UST in their August 11, 2020 email: “Has any remediation been done at the site? If yes, what has been done to remove free product…excavation?…MMPE? (how may events?)…Other? What has been the cost? Has it been effective? Why do you think that it has/has not been effective? Please give numbers to justify that the present course of action is not working…cost, thickness of free product through time, extent of the free product plume (increasing, decreasing, stable). A figure of the free product on groundwater was provided. That is helpful. However, the UVOST would be focused on soil. What do the soil contaminant levels look like? Please provide the cross-sections and figures that outline soil contamination above the residential standards. Do you think that free product may exist in areas that have not been assessed such as under the water table?...in the smear zone? Is another remediation approach needed?” After answering the questions posed in August, Terraquest responded the same day to a September, email from the NCDWM-UST that stated: “As the last sample event occurred just over a year ago in July 2019, I think the UST group can review the site for a feasibility study. We would need the following information that should have been included in the last monitoring: 1. Initial and present contaminant mass in both the soil and the groundwater. 2. The specific remediation technology that you would like to be considered.” Terraquest’s response: 1. (mass presented in units previously requested by NCDWM-UST’s Section Chief) Initial: Soil 33,953,588,327 mg in 82,066 ft3, Free-phase product = 960 gallons, Dissolved groundwater mass = 111,301,120 mg in 23,371 ft3 Present: Soil 6,360,316,827 mg in 54,876 ft3, Free-phase product = 435 gallons, Dissolved groundwater mass = 16,282,338 mg in 8,502 ft3 2. Terraquest recommends surfactant injection followed by MMPE or SVE followed by air sparging. 9. Summary of CAP Implementation (continued) CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 12 428 N. Bridge Street, Jonesville, NC An October 2020 email from Terraquest requesting an update was responded to with an NCDWM-UST email stating: “will be preparing the site early next week, along with three other sites, for internal review to determine if a feasibility study should be done on the proposed remediation method.” A November 2020 email from Terraquest requesting an update was responded to with an NCDWM-UST email stating: “putting together some information now for UST to review to consider your site for a feasibility study.” A February 2021 email from Terraquest requesting an update was responded to with an NCDWM- UST email stating: “Please send in a TA for sampling. promise to review for feasibility study.” On November 19, 2021, a virtual meeting was held to discuss the future of the site. In attendance were representatives from the regional office, trust fund, the corrective action branch head, and Terraquest. The NCDEQ directed the RP to investigate corrective action via active methods. As part of this CAP Feasibility Study, Terraquest supervised the installation of wells SVE3 and RW2 on March 1, 2022. The wells were installed by an NC-licensed driller operating a Geoprobe Model 7822DT drilling unit. The SVE well was constructed for an SVE pilot test and well RW2 was constructed to aid in dual-phase pilot testing via MMPE. Well construction details are provided on Table 4 and on the records provided in Appendix D. Information on the pilot testing is provided in future sections of this report. 9.

Soil analytical results from those assessments are detailed on Tables 5 and 6. The sample locations are shown on Figure 5. The assessment results identified two areas of soil contamination containing petroleum-type contaminant concentrations grater that the STG MSCCs applicable to this Intermediate Risk site. The first area is centered on the closed 10,000-gallon bulk USTs (T5 – T10) and associated loading rack. The extent of soil contamination around this area was delineated using current and historical analytical data. Using a depth to water of approximately 24 feet and a contaminated soil thickness of 12 feet (12 – 24 feet), a 20% reduction in volume due to the sloping nature of the contamination, and a 25% margin of error, Terraquest estimates the volume of contaminated soil to be around 1,900 tons. The second area of identified soil contamination is centered on former USTs T1 – T4 and their associated product lines, and dispensers. Risk based soil analysis revealed an area of contaminated soil with petroleum-type contaminant concentrations exceeding the Residential MSCCs located in the vicinity of the former dispenser island and southeast side of the former tank pit. The extent of soil contamination could not be fully delineated to the STG MSCCs due to the proximity to North Bridge Street and buried underground utilities. Likewise, soil contamination extends beneath the former Jonesville Amoco building. Using a depth to water of approximately 22 feet and an average (based on heterogeneity of starting depth of CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 18 428 N. Bridge Street, Jonesville, NC contamination) thickness of 10 feet (12 – 22 ft), a 20% reduction in volume due to the sloping nature of the contamination, and a 25% margin of error, Terraquest estimates that the volume of STG MSCC-impacted soil to be 2,800 tons. The volume of soil accessible for excavation in this area is probably only 2,000 tons. Terraquest supervised the excavation of 900.96 tons of contaminated soil in this area during the week of September 9, 2013. The limits of excavation are shown on Figure 5. The NCDWM-UST has requested that the initial and present soil contaminant mass be presented. The units are those previously requested by the Section Chief. Initial soil contaminant mass has been calculated as 33,953,588,327 mg in 82,066 ft3. Current soil contaminant mass has been calculated as 6,360,316,827 mg in 54,876 ft3. As a historical review, the cost to excavate 900.96 tons of contaminated soil in September 2013 was $80,040. 3.3 Groundwater Assessment Throughout various phases of assessment, a total of thirty-two monitoring wells (MW1-30, RW1, RW2) have been installed to delineate groundwater quality. Those wells include thirty-one Type II wells and one Type III telescoping deep well. Wells RW1 and RW2 are 4” in diameter and were constructed for monitoring and recovery. The well locations are shown on Figure 3, their construction is detailed on Table 4. The latest groundwater monitoring event was conducted on March 2, 2022 when Terraquest personnel sampled monitoring wells MW5, MW7-17, MW20-25, MW27, MW30, and RW1. Monitoring wells MW1, MW6, MW18, MW19, MW26, MW29, and RW2 contained free product and were not sampled. Monitoring wells MW2, MW3, MW4, and MW28 are missing or destroyed. Prior to sampling, Terraquest field personnel purged at least three well volumes of CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 19 428 N. Bridge Street, Jonesville, NC water from each well using a new disposable bailer that was then used to retrieve a representative sample. Upon collection, samples were placed on ice pending transit to an NC- certified laboratory for analysis. All wells were sampled for 6200B targeting VOCs found in the subject contaminant, gasoline. At the request of the NCDWM-UST, 5 oxygenates found in gasoline newer than the subject release incident were also analyzed for. Free product gauging and groundwater analytical results reveal the following: Free product: MW1 (2.58’), MW6 (1.69’), MW18 (0.03’), MW19 (1.44’), MW26 (2.17’), MW29 (0.33’), RW2 (0.07’) >GCL: MW11, MW20 >2L Standards: MW5, MW10, MW14, MW15, MW16, MW17, MW21-25, MW27, and MW30 <2L Standards: MW7, MW8, MW9, MW12, MW13, and RW1 The analytical results are summarized on Table 7 and on Figure 6. Historical groundwater analytical data sheets and graphs are provided in Appendix C and the full analytical report is in Appendix E. The NCDWM-UST has requested that the initial and present groundwater contaminant mass be presented as follows. The groundwater mass has been calculated using areas with GCL violations only. This includes the water beneath free product. Initial groundwater contaminant mass has been calculated as 111,301,120 mg in 23,371 ft3. Current groundwater contaminant mass has been calculated as 12,172,227 mg in 8,654 ft3. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 20 428 N. Bridge Street, Jonesville, NC As is historically the case, two areas of violation are noted in the recent results although the greater plume (shown as 2L Standard violation) has them commingling. An area of free product and GCL violations is present around the former UST T1-T4 area. Another free product and GCL violation area is located out back near the bulk UST area at monitoring wells MW6 and MW26. The contaminant plume is approximately the same footprint as it has been historically with recent increases in product that may be due to the fluctuation in the water table.

By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 22 428 N. Bridge Street, Jonesville, NC 4.0 OBJECTIVES FOR CORRECTIVE ACTION AT THE SITE This release incident is ranked an Intermediate Risk based upon the presence of free product and GCL violations. If those are removed, the risk would drop to Low. That is the goal. 5.0 COMPREHENSIVE EVALUATION OF REMEDIAL ACTIONS 5.1 Considered Remedial Methods Remedial actions that have been considered for this release incident include excavation, MMPE, passive and active product bailers, natural attenuation, in-situ blending/injection, pump and treat, dual-phase extraction, soil vapor extraction (SVE), and air sparging. Each of the methods has positive and negative features that are discussed here: Excavation Excavation of accessible material at the front of the property has been conducted. Further excavation was previously denied. MMPE Mobile Multi-Phase Extraction (MMPE) events have been performed at this site with success. However, the cost associated with the events becomes prohibitive due to their temporary nature and offsite disposal costs. Product Bailers Product bailers could aid in removal of some product at the site however, they are limited in their radius of effectiveness and require constant maintenance/adjustments to perform well. The bailers would not treat the dissolved-phase contamination. Passive bailers have previously been denied by the NCDWM-UST. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 23 428 N. Bridge Street, Jonesville, NC Natural Attenuation Natural attenuation of the release incident would take an extremely long time due to the presence of free product and GCL violations. The associated monitoring could go on for decades at an extremely high cost. If other methods can remove most of the contaminant mass, a short- period of monitored natural attenuation would be a good way to verify that the plume is stable or degrading and allow site closure. In-Situ Blending/Injection In-situ chemical oxidation of free-phase petroleum is not the most effective means of removal. The injectants used offer the ability to treat in place without having to remove and dispose of contaminants. While this is beneficial and overcomes the increased cost of this method in many hazardous waste incidents, this release incident is not hazardous. Blending is not a cost-effective realistic means due to the depth of the water table. The effectiveness of oxidant injection varies based on the lithologic heterogeneities and BOD, COD of the aquifer. The large presence of free product negates this method as the best choice. Pump and Treat A pump and treat system would effectively remove dissolved-phase groundwater contamination. It would also be able to retrieve some free product although it has a habit of pinching off product and requires on and off cycling to ensure capture of all product. This method has a higher capital cost and can require frequent maintenance and cleaning. With the lack of a sensitive receptor, the hydrodynamic control offered by this method as one of its main selling points, is unnecessary. Dual-Phase Extraction Following the success of MMPE, a dual-phase extraction (DPE) system would appear a good means of treatment as it is a more continuous method of MMPE. It is better at product recovery as it can reduce through vapor recovery also. Terraquest has previously obtained a tentative okay for treated water placement into the sanitary sewer system. The NCDWM-UST has indicated that this is the method they would prefer. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 24 428 N. Bridge Street, Jonesville, NC Soil Vapor Extraction Soil vapor extraction (SVE) applies a vacuum to the vadose zone soil to remove VOCs that are then emitted to the atmosphere. The method is also capable of recovering liberated sparge vapors. The method is lower in cost than other active methods and generally operates well with little down time. Recovered vapors would require treatment prior to exhaust to eliminate the VOCs and ensure emissions requirements are met. The method is limited by the permeability of the soil matrix. Air Sparging Air sparging uses compressed air applied to the aquifer to liberate dissolved-phase contaminants that can then be exhausted to the atmosphere. Compared to the other active methods, air sparging is a lower-cost option. Air sparge systems generally run well with little down time. The effectiveness of this method is limited by hydrogeologic heterogeneities and lower permeable aquifer material. Air sparging was previously denied by the NCDWM-UST. Terraquest recommends supplemental air sparging at a minimum including vadose-zone air injection to aid DPE-vacuum. 5.2 Pilot Testing Following discussion, agreement, and pre-approval of costs from the NCDWM-UST, Terraquest personnel conducted an SVE pilot test On April 13, 2022 and a DPE pilot test in stages from March 14-25, 2022. 5.2.1 SVE Pilot Test As detailed in Appendix F, Terraquest performed SVE pilot testing on April 13, 2022. The process involved the application of vacuum to an extraction well while monitoring other wells nearby for influence. Much can be learned from a successful series of tests, however, little or no influence was seen throughout testing at the Jonesville Amoco B site. Overall, the lack of influence, lack of CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 25 428 N. Bridge Street, Jonesville, NC recovered vapors as documented through a collected air sample, noted clay in the soil lithology, and the semi-volatile nature of some of the contaminants all make SVE a less than ideal treatment method. At this time, Terraquest does not recommend SVE. 5.2.2 Dual-Phase Extraction Pilot Test The use of dual-phase extraction as a remedial method was investigated via pilot testing in stages from March 14-25, 2022. A liquid-ring pump from an MMPE unit was used to apply vacuum to the subsurface and nearby wells were monitored for influence. Data was collected to show the effectiveness of this method and for system design. Air samples were collected from the exhaust stack to evidence recovery. Note that these samples were incorrectly labeled as “SVE” samples. On March 14, 2022, Terraquest supervised the application of vacuum to well RW2. MMPE services were provided by EarthX of Mebane, NC. During this first stage, an aggressive vacuum was applied to the well and a stinger pipe was advanced into the well. As shown in the analytical reports provided in Appendix E, a sample collected on March 14 had a reported concentration of 8,190,000 ppbv. This confirms the ability of a liquid ring pump’s high vacuum to recover vapors. As shown in Appendix G, following two and one-half days of aggressive vacuum application, 5,287 gallons of liquid (free and dissolved-phase) were recovered. This confirms the method’s effectiveness. The vacuum unit was shut off and the aquifer allowed to recover. One March 21, 2022, Terraquest supervised the second half of the MMPE test wherein the stinger pipe was placed higher in the well to recover total fluids. The unit operated from March 21 – 25, 2022 and as shown in Appendix G’s manifest, recovered 2,258 gallons. The analytical reports in Appendix E show the recovery of 4,240,000 ppbv in a March 21 air sample, 3,210,000 ppbv for the March 23 air stack sample, and 4,830,000 ppbv for the March 25, 2022 air stack sample. The measurements collected throughout the event, shown in Table 8, reveal influence at all wells observed throughout the week. The following graph shows a radius of influence of ~25 feet based on linear data trending and where vacuum is estimated to reach 0.1 inches of water. That CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 26 428 N. Bridge Street, Jonesville, NC relationship is laid out as a rule of thumb by the EPA in their guidance document “How to evaluate alternative cleanup technologies for underground storage tank sites.” (1995). In addition to the previous MMPE events at this site, the recent pilot testing supports dual-phase extraction as a remedial method. Based on the reported influences, Terraquest recommends extraction at wells as shown on Figure 7. This includes the installation of two additional wells. 5.3 Chosen Remedial Methods Based on the factors discussed, Terraquest chooses dual-phase extraction as the method to remove free product and GCL violations. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 27 428 N. Bridge Street, Jonesville, NC 5.4 Contaminant Mass Removal Estimates While the exact time required to remediate the free and dissolved-phase contamination is unknown, pilot test data can be used with previous assessment data to provide a very rough estimation. Essentially, the metrics involved are the starting mass of product, the starting mass of dissolved-phase contamination, and the removal rate of the system. The largest problem with these calculations is that early operation of a system releases untethered contamination VERY easily whereas later operation of a system requires the rise and fall of the aquifer and the release of contaminants bound up in pore spaces to provide MUCH slower remediation. Some sort of reasonable multiplier or logarithmic decline in recoverability must be used to provide a realistic cleanup time. Soil contaminant mass: As previously noted, current soil contaminant mass has been calculated as 6,360,316,827 mg in 54,876 ft3. Free-phase product mass: Free product is present in two areas totaling 1,890 square feet. With an average product thickness estimated at 1.5 feet and an effective porosity of 0.15, the mass is calculated as follows: 1,890 ft2 x 1.5 ft x 0.15 = 425.25 ft3 x 6.2 pounds/gallon x 7.48052 gallons/ft3 / 2.20462-6 pounds/mg = 8,946,106,361 mg in 425.25 ft3. Dissolved-phase contaminant mass (GCL violation): As previously noted, current groundwater contaminant mass has been calculated as 12,172,227 mg in 8,654 ft3. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 28 428 N. Bridge Street, Jonesville, NC The volume of water that needs to be removed to recover the GCL mass varies based upon geologic heterogeneities including variable porosities, variable contaminant desorption rates based on differing compounds and degrees of weathering, and tailing effects of contaminant recovery as treatment progresses. The pore volume of water is equal to the GCL violation area (8,656 ft2) multiplied by the thickness (18 ft) times the effective porosity (15%) times 7.48052 gallons/ft3 for a value of 174,817 gallons. A very rough estimate of the required volume of water that is required to be removed for the GCL plume to become absent is 3 to 4 pore volumes or 525,000 to 700,000 gallons. That is the amount of GCL-contaminated water ONLY. Recovery will likely include water outside the area of GCL violations. Accounting for that intake flux, a 1.5 multiplier yields a volume of 787,500 to 1,050,000 gallons. Dual-phase removal rate: Using measurements collected during the dual-phase pilot test (MMPE) and the analytical results of the air samples, the following removal rate was calculated: Operating period:START: 3/21/22 12:00 PM END:3/25/22 12:00 PM Measured scfm flow rate:300 scfm Is the dilution valve open? Subtract dilution flow rate:0 scfm Average TPH concentration of vapors at stack for this period: 4,240,000 ppbv, 3,210,000 ppbv, 4,830,000 ppbv 4,093,333 ppbv Volume of air removed in ft3 equals (flow)(1440 min/day)(days in this period)1,728,000 ft3 Volume of gasoline vapor removed is equal to air volume removed muliplied by the TPH concentration. Vol. air removed (ft 3) x [TPH concentration of vapor (ft3 gasoline vapor/1E+09 ft3 air)]7,073 ft3 gasoline vapor 1 ft3 vapor equals 7.48 gal. 1 gal. equal 3.78 liters ft3 gasoline vapor x 7.48 gal./ft3 x 3.78 liters/gal. equals liters gasoline vapors.199,993 liters gasoline vapor At standard temperature and pressure, there are 22.4 liters of gasoline vapor per mole of gasoline. The molecular wt. of carbon in gasoline is 89 g/mole. 89 g/mole x (1mole/22.4 liters) equals:3.97 g/liter Amount of Contaminant Removed gasoline vapor (liters) x (3.97 g/liter) x (1,000 mg/1 g) equals mg vapor 793,971,209.69 mg of gasoline per 96.00 hours Conversions: Conversions: Therefore: CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 29 428 N. Bridge Street, Jonesville, NC _____With a total mass of_____ 6,360,316,827 mg soil 8,946,106,361 mg product _____12,172,227 mg GCL groundwater_____ Sum = 15,318,595,415 mg total And a removal rate of 793,971,209.69 mg/96 hours, the mathematical total time it will take calculates to 1,852 hours. So, if a treatment system were installed that had removal rates like those of the pilot test, the contaminant mass would be removed in 77 days. This value isn’t a realistic cleanup time. Generally, there is a logarithmic decline in contamination recovery following evacuation of readily accessible pore-space contamination. Heterogeneities, bound particles, and recalcitrant contaminants along with rising and falling water table elevations will affect treatment. At some point, dual-phase extraction recovery at similar sites has shown a drastic reduction as the system run time increases. Having over a foot of free product available for removal may allow the “early and productive” stages of the system to last longer than sites treating dissolved-phase contamination alone. All of this is to say that the site will not be rid of product and GCL violations in 334 days. A 2-3 times factor should be applied along with a year or two of time to allow for water table fluctuations that may trap product/GCL violations from treatment. Three to four years of operation is more in line with observed results at similar sites. This time frame will increase with denied operation and maintenance visits from the NCDWM-UST. Further refinement of treatment time will be understood as the system is operated. 5.5 Remedial System Operation and Maintenance Plan Terraquest proposes two, 6-hour visits per month to perform system O&M activities and adjust vacuum pipe settings and two, 2-hour visits per month to simply adjust stinger pipes. A total of four visits per month is recommended. O&M activities will include maintenance as CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 30 428 N. Bridge Street, Jonesville, NC recommended by the manufacturer and the collection of data as is helpful to this investigation. In addition to an overall system check, equipment temperatures and run hours will be inspected/adjusted/recorded. An overall check for air, water, and lubricant leaks should be conducted. The system’s heater and exhaust fan should be inspected/adjusted/setting recorded. The pressures and flows of the dual-phase system and lines to wells will be inspected/adjusted/recorded. The operating pressures of the liquid-ring pump (LRP) should be verified and recorded. An oxidizer will likely be required and should have temperatures recorded and maintained as required. The system’s logic controller should be inspected. System valves including, ball valves and solenoid valves, and floats will be checked for proper operation and serviced as needed. System alarms should be operationally verified along with the variable frequency device for the LRP, pressure relief valves, system lights, hand-off-auto switches, contacts, and overloads. Sight tubes should be inspected/cleaned/replaced across the system. The volts and amps across the system will be recorded. Aftercoolers will be cleaned and adjusted as necessary. Pre-intake and air intake filters will be inspected/cleaned/replaced as needed. Lubricants and associated filters and separator elements will be maintained along with any scavenge lines, orifices, and filters. 5.6 Monitoring Plan Terraquest recommends quarterly sampling of the entire monitoring well network following system startup to measure treatment and plume migration. During those events, free product thickness measurements should be collected, and dissolved-phase contamination will be investigated by lab analysis of VOCs via 6200B samples. Contaminant recovery and treatment system operation should be investigated through monthly collection of air samples from the dual phase system’s intake that are submitted for ab analysis per method EPA18 targeting BTEX, MTBE, and TPH. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 31 428 N. Bridge Street, Jonesville, NC Following the first year of operation, semi-annual monitoring events may be sufficient. Additional data collection may be required as treatment unfolds to better understand the geochemistry and ensure that contamination is removed in the most cost-effective manner. 5.7 Remedial Schedule Following submittal of this report, the following schedule is anticipated: • one month is anticipated for the NCDWM-UST to review it and respond, • one week is anticipated for pre-approval of the Corrective Action Design Report (CADR) cost, • three months are anticipated to design the system and acquire bids and the RP’s authorization for system placement, • one month is anticipated for the NCDWM-UST to review the CADR and respond, • one week is anticipated for pre-approval of the Record of Decision (ROD), • one month is anticipated to write the ROD and submit it, • one month is anticipated for the NCDWM-UST to review the ROD and respond, • one month is anticipated for all parties to meet and sign the ROD, • one week is anticipated for pre-approval of the system costs and supervised installation, • three months are anticipated for construction of the system, • three months are anticipated for installation, inspection approval, utility construction and activation, • one month is anticipated to schedule system startup. A total time of 15 months and three weeks are anticipated until the treatment system will be turned on. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 32 428 N. Bridge Street, Jonesville, NC Following system activation, Terraquest expects the majority of free product will be removed within the first year of system operation with another year to get it down to small pockets and treated in water-table fluctuation trapped areas. The surrounding dissolved-phase contaminant plume will be reduced during these first several years of operation and another year or two will likely be needed to get concentrations below the GCLs to suspend system operation and monitor natural attenuation. Following a year of monitored natural attenuation, it may be possible to reduce the risk ranking of this site and move toward closure. In total, it will take 16 months to activate the system, 3-4 years of operation to remove the bulk of the contamination, and another year to monitor natural attenuation and close the incident. Without any alterations or delays to this schedule, a Notice of No Further Action could be release in December 2028. While it is possible that this could be accomplished quicker, experience has shown that it will most likely take longer. This time frame will increase with denied costs from the NCDWM-UST. 5.8 Rough Cost Estimate The life-cycle cost of a dual-phase extraction system operating for three years is expected to roughly cost $702,678. Costs are estimated on Table 10 and summarized as follows: As listed, the cost includes $8,000 for CADR, ROD, and public notification, $6,835 for remedial well installation, $304,476 for system installation and equipment, $61,350 for groundwater CADR 5,500.00$ ROD 1,500.00$ Public notification (CADR and ROD)1,000.00$ Remedial well install 6,385.00$ Supervised treatment system installation 304,476.00$ Life cycle sampling 61,350.00$ Sytem operation and maintenance:314,415.00$ Closure:9,052.00$ 703,678.00$ CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C. Jonesville Amoco-B Report Prepared: September 26, 2022 33 428 N. Bridge Street, Jonesville, NC monitoring, $314,415 for system O&M, and $9,052 for public notice, NORP, and monitoring well abandonment. Note that the cost of a rental DPE recovery and treatment system was investigated. The cost of a suitable rental unit is around $10,000 per month. That would include a DPE liquid ring blower, oil/water separator, air stripper, bag filters, carbon filters, and oxidizer. The purchase of a system that would cost $200,000 while the three-year rental of such a unit would cost $360,000. Purchasing the system is the cheaper way to go. 5.9 Permits Permits required for the proposed remedial actions will include a Publicly Owned Treatment Works permit for the discharge of treated water and a building permit for the placement of the remedial building that will house all the equipment. Terraquest has previously corresponded with Benjamin (Benjie) B. Thomas, PE of West Consultants PLLC located in Morganton, NC who gave positive indications that the POTW discharge permit could be obtained. West Consultants handles the POTW issues as such for the town. The discharge permit will require VOC analysis to ensure compliance. Those costs have been factored into Table 10. 6.0 CONCLUSIONS / RECOMMENDATIONS In consideration of the contamination present and treatment methods investigated, Terraquest recommends DPE for the Jonesville Amoco B release incident. This method proved practical during pilot testing. Terraquest roughly estimates that 3-4 years of operating a DPE remediation system followed by a year of monitored natural attenuation could allow closure of this site in 2028 at a cost of $689,000. While previously denied, Terraquest asks that the NCDWM-UST consider the addition of several air sparge points to the remedial plan to speed efforts along and reduce costs. If the NCDWM-UST agrees, the next step is to generate a CAP Corrective Action Design Report. CAP Feasibility Report Beroth Oil Company, Inc. By: Terraquest Environmental Consultants, P.C.

Cleaning solutions range from clean potable water to acidic solutions or organic solvents depending on the contaminants present at the site. Equipment utilized at sites, such as hand augers, contaminated with petroleum hydrocarbons, is generally decontaminated with a low‐sudsing detergent such as Luiquinox® and triple rinsed with distilled water. Larger equipment, such as drill rigs and associated tools, is steam cleaned. All decontamination procedures are completed within an established decontamination area which is located away from the active study area. Frequency of equipment decontamination depends on the nature of work being performed, but in no case is decontamination performed less frequently than once per test (i.e., soil boring, well installation, sample collection, etc.). Equipment blanks are collected as a quality control measure when required by job specifications. Soil Boring Installation Soil borings are completed using hand‐operated sampling tools, truck‐mounted drills, or Geoprobe® drilling rigs depending on the depth of sample collection and other site‐specific conditions. Hand operated stainless‐steel bucket augers are utilized to collect soil samples at regular intervals to determine site stratigraphy and to test for the presence of volatile organic compounds. Samples retrieved from the hand auger are necessarily disturbed during the augering process, but can provide accurate information on soil type and contaminant concentrations when properly interpreted. Soil samples from hand augered borings are generally retrieved at one to two foot intervals. Truck‐mounted or Geoprobe® drilling equipment is often utilized when sample retrieval depths exceed twenty feet or subsurface conditions prevent utilization of hand augers (i.e., buried rocks, wood, bricks or other materials occur in the subsurface). Truck‐mounted drilling rigs usually retrieve soil via a hollow‐stem auger/split spoon collection method. Geoprobe® rigs usually employ a Macro‐Core® tube retrieval system. Hollow stem augers provide relatively undisturbed 2‐foot cores of soil samples. Soil samples are generally collected at five foot intervals utilizing standard penetration test procedures as defined by the American Society for Testing and Materials (ASTM) or are pushed to the desired depth using the head of the drill rig. The standard penetration test involves driving a 2" outside diameter by 1‐ 3/8" inside diameter split‐spoon sampler a minimum distance of one foot with a 340‐lb. slide hammer falling a distance of 30 inches. A Geoprobe® rig is a hydraulically‐powered soil probing machine. The probe utilizes static force and percussion to advance a small diameter sampling device into the subsurface. The sampling apparatus provides relatively undisturbed 5‐foot cores of soil samples. Soil samples are collected Page 2 of 8 continuously. The Macro‐Core® tube contains an inserted poly‐vinyl chloride (PVC) liner which retains the soil sample as the tube is driven into the ground. The Macro‐Core® tube is decontaminated between each 5‐foot sample interval in a soil boring using a Liquinox and tap‐ water mixture. A new PVC liner is used to collect soil from each sample interval in a soil boring. Soil samples retrieved from the hollow‐stem augers or Geoprobe are then carefully described according to the Unified Soil Classification System. Soil descriptions are recorded on a soil boring log. Soil Sampling Soils to be analyzed by a North Carolina‐certified laboratory are prepared according to the specified analytical method. Initially, soil samples are removed from the ground using either a hand auger, backhoe bucket, spilt spoon auger, or a Macro‐Core® sampling tube. During the removal, care is taken to keep the disturbance of the soil structure to a minimum to reduce the loss of contaminants. Once removed, the samples are placed in the proper sample container for the specified analytical method. For samples collected for the MADEP VPH and EPA Method 8260, a TerraCore® sampler is used to collect one 5‐gram allotment of soil. The allotment is placed in methanol‐preserved 40 mL vials. Also, one 5‐gram allotment of soil is placed into sodium bisulfate‐ preserved 40 mL vials (one 5‐gram allotment per vial, 2 vials per sample) for the 8260 low concentration method. A 250‐mL glass jar of the sampled soil is also collected to provide moisture content information. Soils sampled for MADEP EPH, EPA Method 8270 and TPH 5030 and 3550 are placed in a 250‐mL glass jar (for MADEP EPH analysis an amber jar is required). TPH 5030 samples are preserved in methanol similar to the 8260 analysis. Field personnel wear new, disposable nitrile gloves during the collection of each sample. The soil samples are labeled with the sample location, sample identification, date and time of collection, and the analytical method. The samples are placed on ice, sent to a laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. If the soil is being sampled for volatile or semi‐volatile compounds, a portion of the collected soil is placed in a sealable bag and screened for volatile organic vapors. Head screening procedures are described in the following paragraph. Headspace Screening Collected soil samples are routinely tested for the presence of volatile organic compounds (VOCs). After retrieval from the ground, a portion of a soil sample is placed in a sealable plastic bag. The soil samples are then set aside for approximately five minutes so that volatile constituents present in the sample can reach equilibrium concentrations with headspace gases in the bag. Once a suitable time period has passed, the probe of the sampling instrument, typically an Organic Vapor Monitor (OVM) or a Photo Ionization Detector (PID), is inserted into the bag and the relative concentration of total VOCs is measured and permanently recorded in a field note book. VOC Page 3 of 8 concentrations are measured using either a Thermo Electron Corp. Innova Series catalytic OVM or an Ion Science PhoCheck PID. Both the OVM and PID instrumentation are periodically calibrated according to the manufacturer’s recommended procedures. The OVM and PID are qualitative tools employed to detect and estimate the concentration of organic or hydrocarbon vapors. A thin probe is inserted through a small break in the seal of a bagged soil sample. For the OVM, an air sample from the headspace of the bag is drawn through the probe into an internal chamber where the vapors are catalyzed. The concentration of the VOCs is registered on a digital scale in parts per million (ppm). For the PID, an air sample from the headspace of the bag is drawn across the face of a lamp causing the sample to emit photons, the presence of which are converted into a VOC ppm reading that is displayed. Oxygen levels are field calibrated prior to each use. VOC calibration occurs periodically depending upon use by using a span gas of known concentration in a process recommended by the manufacturer. Well Installation/Construction Monitoring wells are installed using hand‐operated sampling tools, a truck‐mounted drill rig, or a Geoprobe drilling rig depending on the depth of well and other site‐specific conditions. All monitoring wells are installed according to the requirements of 15A NCAC 2C‐Well Construction Standards. Specifically, individual monitoring wells are constructed of 2‐inch diameter, schedule 40 PVC casing riser and screen. The screen interval is generally 10 to 15 feet of machine slotted PVC with a slot size of 0.010". Only flush threaded joints are used. The annulus space around the screen is filled with washed filter pack No. 2 sand. The filter pack extends one to two feet above the top of the screen. A one to two foot‐thick bentonite pellet seal is then placed above the filter pack. The remainder of the well annulus is completely filled with a Portland (Type I/II) cement grout mixture. A protective outer steel manhole, locking cap, and concrete pad is installed for each well. Type II Monitoring Well Construction Single‐cased monitoring wells are generally used in delineation of groundwater quality within the surficial aquifer. The wells are constructed of 2‐inch diameter, schedule 40 PVC casing and screen. The screen interval is generally 10 to 15 feet of machine slotted PVC with a slot size of 0.010". Only flush threaded joints are used. The annulus space around the screen is filled with washed filter pack No. 2 sand. The filter pack extends one to two feet above the top of the screen. A one to two foot‐thick bentonite pellet seal is then placed above the filter pack. The remainder of the well annulus is completely filled with a Portland (Type I/II) cement grout mixture. A protective outer steel manhole, locking cap, and concrete pad are installed for each well. Type III Monitoring Well Construction Double‐cased monitoring wells are used in the delineation of groundwater quality within a deeper portion of the surficial aquifer or an additional aquifer (e.g. aquitard, bedrock). A four to six‐inch outer casing is installed through the surficial aquifer until a sufficient depth or until the deeper Page 4 of 8 aquifer is encountered. The casing is secured with a Portland‐grout collar that is tremmied into the annular spaced from the bottom of the bore hole to the surface. Once the grout has sufficiently cured, the bore hole is continued through the bottom of the outer casing to a depth approximately 15 ‐ 20 feet beneath the outer casing. The inner casing is constructed of 2‐inch diameter, schedule 40 PVC casing riser and screen. The screen interval is generally 5 to 10 feet of machine slotted PVC with a slot size of 0.010". Only flush threaded joints are used. The annulus space around the screen is filled with washed filter pack No. 2 sand. The filter pack extends one to two feet above the top of the screen. A one to two foot‐thick bentonite pellet seal is then placed above the filter pack. The remainder of the well annulus is completely filled with the same Portland grout mixture used in the outer casing. A protective outer steel manhole, locking cap, and concrete pad are installed for each well. Well Development Following installation of each well, surging and pumping or bailing techniques will be used to remove fines from the screened interval. Groundwater is removed from each well until clear water is retrieved or a noticeable reduction in the amount of silt is achieved. Purged groundwater is disposed of in an environmentally safe manner. Groundwater Sampling Petroleum Sites Groundwater samples are collected from temporary or permanent monitoring wells according to established sampling protocol. When multiple monitoring wells or sampling points are sampled, sampling is completed beginning with the least contaminated well to the most contaminated well, if it is known. When permanent monitoring wells for petroleum sites are sampled, the well is purged of a minimum of three well‐bore volumes prior to sample collection in order to assure that sampled water is representative of aquifer conditions. In temporary wells, the first water which migrates into the open borehole is sampled. Samples from both temporary and permanent monitoring wells are collected using individually wrapped disposable polyethylene bailers by field personnel wearing disposable nitrile gloves. Only one well is sampled with a given bailer in order to prevent sample cross‐contamination. During both well purging and sampling, proper protective clothing and equipment is used and is dependent upon the type and level of contaminants present. Also, field personnel change gloves between different samples to reduce the chance of cross‐ contamination. Water samples are transferred from the bailer to laboratory‐prepared sampling containers using slow emptying devices to reduce the chance of contamination loss through volatilization. Preservatives, such as acids, are provided by the laboratory in pre‐prepared containers in which collected samples are placed if in‐field preservation is necessary. The samples are labeled with the project name, project number, sample identification, required analysis, and date and time of collection. The samples are placed on ice, shipped to a certified laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. Page 5 of 8 Other Groundwater Sampling Protocols When required by state or federal regulations, low‐flow groundwater sampling procedures are instituted. Groundwater samples collected in low‐flow situations are collected using a peristaltic pump. A peristaltic pump is a type of positive displacement pump. The fluid is contained within a flexible tube fitted inside a circular pump casing. A rotor with a number of rollers attached to the external circumference compresses the flexible tube. As the rotor turns, the part of tube under compression closes thus forcing the fluid to be pumped to move through the tube. Groundwater parameters such as water level drawdown, pH, conductivity, dissolved oxygen (DO) and turbidity. Pumping rate, drawdown, and the time or volume required to obtain stabilization of parameter readings can be used as a future guide to purge the well. Measurements are collected at a pre‐ pumping established interval (typically five to ten minutes). Once all or a majority of the parameters have stabilized for three successive readings, stabilization has been achieved. In lieu of measuring all five parameters, a minimum subset would include pH, conductivity, and turbidity or DO. Three successive readings should be within ± 0.1 for pH, ± 3% for conductivity, and ± 10% for turbidity and DO. Upon parameter stabilization, sampling is initiated. Sampling flow rate is maintained at the estab‐ lished purge rate or is adjusted slightly to minimize aeration, bubble formation, turbulent filling of sample bottles, or loss of volatiles due to extended residence time in tubing. The same device used for purging is used to collect the groundwater sample. Generally, volatile parameters are sampled first. The sequence in which samples for inorganic parameters are collected is not determined unless filtered (dissolved) samples are collected. Preservatives, such as acids, are provided by the laboratory in pre‐prepared containers in which collected samples are placed if in‐field preservation is necessary. The samples are labeled with the project name, project number, sample identification, required analysis, and date and time of collection. The samples are placed on ice, shipped to a certified laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. During both well purging and sampling, proper protective clothing and equipment is used and is dependent upon the type and level of contaminants present. Also, field personnel change gloves between different monitoring wells or sampling points to reduce the chance of cross‐ contamination. When multiple monitoring wells or sampling points are sampled, sampling is completed beginning with the least contaminated well to the most contaminated well, if it is known. Stockpile Sampling The number of composite samples collected from a stockpile or a total quantity of excavated soil is based upon the cubic yardage. One composite sample is collected for every 100 cubic yards of contaminated soil excavated. The volume of a stockpile or total quantity of excavated soil is calculated by approximating the general geometry of a stockpile or estimating the capacity of the Page 6 of 8 dump trucks used for hauling. If a stockpile is sampled, a grid pattern is laid out on the stockpile, dividing the stockpile into segments of approximately 200 cubic yards. Two soil borings are advanced within a grid and three soil samples are collected from each soil boring at various depths. The six soil samples are mixed into a composite sample by a trained TerraQuest technician. If truck loads are sampled, an aliquot sample is collected from the hauling trucks at a frequency based upon the capacity of the hauling trucks. Aliquots are gently mixed into a composite sample by a trained TerraQuest technician. Every effort is made to minimize the loss of contaminants through volatilization. The composited soil samples are jarred in the appropriate laboratory‐prepared containers, labeled with the sample location, sample identification, date of collection, time of collection, the analytical method, and the preservative. The samples are placed on ice, shipped to a laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. Surface Water Sampling Surface water samples, specifically samples from creeks or streams, are collected from a moving/flowing portion of the creek or stream to ensure that stagnant water is not collected. Field personnel are careful to collect samples from flowing areas that are not so turbulent as to cause a loss of volatile contaminants which might have been contained in the creek’s/stream’s water. Samples are collected by field personnel wearing disposable nitrile gloves. Field personnel change gloves between different locations to reduce the chance of cross‐contamination. Samples are collected directly from the appropriate creek or stream location and placed into the appropriate laboratory‐prepared containers. Preservatives, such as acids, are provided by the laboratory in pre‐ prepared containers in which collected samples are placed if in‐field preservation is necessary. The samples are labeled with the project name, project number, sample identification, required analysis, and date and time of collection. The samples are cooled on ice to approximately four degrees centigrade, shipped to a certified laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. Potable Well Sampling Groundwater samples from potable wells are collected from sampling points, typically spigots, located in the closest proximity to the potable well pump house as possible. Prior to sample collection, the water is run for a sufficient amount of time to purge the bladder tank and assure that sampled water is representative of aquifer conditions. Once purged, the flow rate is reduced and samples are placed in the appropriate laboratory prepared containers with the appropriate acid preservatives added if preservation of the sample is necessary. The samples are labeled with the project name, project number, sample identification, required analysis, and date and time of collection. The samples are placed on ice, shipped to a laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. Page 7 of 8 Public Water Supply Line Sampling Groundwater samples from public water supply lines are collected from sampling points, typically spigots. To sample the spigot, the flow rate is reduced and samples are placed in the appropriate laboratory prepared containers. The samples are labeled with the sample location, sample identification, date of collection, time of collection, and required analytical method. The samples are placed on ice, shipped to a laboratory, and analyzed before the expiration of an analytical method’s prescribed holding time. Chain‐of‐custody documentation is maintained for each sample collected in the field. Air Sampling Air samples are collected with the aide of a manually operated MityVac® pump manufactured by Pristech, Inc. The air sampling process begins by connecting a length of rubber hose from the MityVac® pump to the port to be sampled, or by hanging the hose inside of an emissions stack in such a manner as to ensure no outside air causes dilution. Another length of hose is fixed to the outlet port of the pump and is connected to a new Tedlar bag. Once the pump is hooked up, a valve on the Tedlar collection bag is opened and air is manually forced into the bag by the pumping action of sampling personnel. Field Measurements Field measurements taken to determine the pH, conductivity, temperature, and dissolved oxygen concentration of a particular groundwater sample are taken directly after a particular monitoring well has been adequately purged. This ensures that the groundwater parameter data collected is representative of the aquifer conditions at a given location. Once purging of the monitoring well is complete, the decontaminated probe head and cord of the appropriate unit is lowered into the required monitoring well. If the depth to water in a specific monitoring well is greater than the length of cord for a particular unit, a new, disposable bailer is slowly lowered into the appropriate monitoring well and a representative groundwater sample is retrieved. A slow pouring device is fitted onto the end of the disposable bailer and the sample is slowly poured into a new, disposable plastic cup. Groundwater parameter data are then collected from the groundwater in the cup using the required unit. For pH, conductivity, and temperature, a Hanna Instruments Model 991300 portable meter is utilized. This unit is periodically calibrated and maintained in accordance with the unit’s operations manual by field personnel. Prior to data collection, the unit is properly decontaminated to prevent cross‐contamination. The unit is decontaminated between each sample. The procedure used for sample measurement involves lowering the meter’s probe into the new, disposable cup containing the groundwater sample to be measured and slowly stirring the probe to force groundwater across the probe’s membrane. The measurements displayed by the meter are then recorded. For dissolved oxygen concentration measurements, a YSI® Model 55 Handheld Dissolved Oxygen System is utilized. This unit is periodically calibrated and maintained in accordance with the unit’s Page 8 of 8 operations manual by field personnel. Prior to data collection, the unit is properly decontaminated to prevent cross‐contamination. The unit is decontaminated between each sample. The procedure used for sample measurement involves adjusting the unit for the correct altitude where the sampling will take place and adjusting the reported units desired. Once this is done, the unit’s probe is inserted into the groundwater sample to be measured and the probe is slowly stirred to force the groundwater across the probe’s membrane. The measurements displayed by the unit are then recorded. For turbidity measurements, a Hach 2100P Portable Turbidity meter or equal equivalent is utilized. The unit is calibrated prior to use in accordance with the unit’s operations manual by field personnel. Groundwater samples are collected in glass containers for measurement by the instrument. The glass containers are washed with bottled‐water between each measurement collection. Once the sample is collected and inserted into the instrument, the measurements displayed by the instrument are then recorded.

The notification was for the removal of two 1,000-gallon gasoline USTs located at the Jonesville Amoco facility. 2/11/91 Beroth Oil Company submitted a UST closure report for the closure of one UST and the in place abandonment of another. The report indicates that soil samples were collected at depths of 18 – 24 inches below the tank bed and that there were no detections in any of the collected samples. 8/28/91 Beroth Oil Company submitted an Amended UST Closure Report indicating that the second 1,000-gallon UST had been removed in lieu of abandoning in place. 11/9/93 A Notice of Violation was issued by NCDEHNR. The NOV stated that an inspection of the UST system on October 22, 1993, indicated that USTs on the subject property were not in compliance with 15A NCAN 2N, “Criteria and Standards Applicable to Underground Storage Tanks. 11/17/93 A Notification of Tank Closure Form was submitted by Beroth Oil Company. The notification was for the removal of one 1,000-gallon kerosene UST and one 1,000-gallon fuel oil UST. 12/18/1993 One 1,000-gallon #2 fuel oil UST and one 1,000-gallon kerosene UST were removed from the Amoco service station. Analytical results for soil samples collected from beneath the USTs indicated the presence gasoline contamination, as opposed to higher boiling point fuels (kerosene/fuel oil). Beroth Oil Company submitted a UST Closure Report on January 18, 1994. 2/4/94 Monitoring well MW1 was installed in the vicinity of the former 1,000- gallon diesel and 1,000-gallon kerosene UST excavation. During the installation of the monitoring well, soil samples were collected at depths of 10 and 22 feet BGL. Analytical results for the collected soil samples revealed petroleum contamination at concentrations exceeding 4,000 ppm. Analytical results for groundwater samples collected from the monitoring well revealed total BTEX concentrations of 7,500 ppb. 100 East Ruffin Street, Mebane, North Carolina 27302 Telephone (919) 563-9091 ·Facsimile (919) 563-9095 www.terraquestpc.com Page 2 of 15 Chromatograms indicated the soil and groundwater samples were contaminated with gasoline rather that kerosene or fuel oil. 2/7/94 A Notification of Tank Closure Form was submitted by Beroth Oil Company. The notification was for the removal of three 10,000-gallon gasoline USTs. 3/31/94 Three 10,000-gallon gasoline USTs and their associated product lines and dispensers were excavated from the Beroth Oil Company bulk storage facility. Soil samples collected during the removal of the UST system revealed the presence of petroleum contamination in excess of the TPH action limit. 4/7-11/94 198 cubic yards of contaminated soil was treated onsite by Soil Solutions, Inc. of Winston-Salem, NC. Analytical results for samples collected from the stockpiled soil following the onsite remediation revealed no detections of petroleum contamination. The treated soil was returned to the excavation. 4/13-14/94 Twelve (12) soil borings were advanced at locations around the site to investigate soil contamination in the vicinity of the former UST system. Analytical results for the collected soil samples confirmed the presence of gasoline contaminants at concentrations in excess of the TPH action limit near the southern end of the UST excavation and at deeper levels beneath the western portion of Amoco station property. Seven monitoring wells (MW2-MW8) were installed at the site to investigate groundwater quality. The monitoring wells were installed April 13 – 18, 1994. 4/21/94 Groundwater samples were collected from the eight onsite monitoring wells. Analytical results for the collected groundwater samples revealed 2L Standard violations in all of the sampled monitoring wells with the exception of monitoring well MW2. The contaminant plume extended beneath the entire Amoco station property and most of the Beroth bulk facility. No free product was detected in any of the monitoring wells. Surface water samples were also collected from a drainage way that runs south to north beneath N. Bridge St. and the western portion of the Amoco station. Analytical results for the surface water samples revealed benzene at concentrations in excess of the 2L Standards in both the upstream (2 ppb) and downstream (1 ppb) samples. 5/20/94 A Notice of Regulatory Requirements was issued by NCDEHNR. The NORR requested the completion of a Comprehensive Site Assessment.

The NOV stated that contaminant concentrations were in excess of the maximum allowable concentrations and were therefore in violation of the groundwater standards. The NOV also requested the completion of a CSA. An extension of the CSA was requested on June 21, 1994. 8/1-2/94 Four (4) monitoring wells (MW9-MW12) were installed at the site to further investigate groundwater quality at the site. Analytical results for soil samples collected during the installation of the monitoring wells revealed petroleum contamination in excess of the TPH action limit in monitoring wells MW10 and MW12. 8/9/1994 Groundwater samples were collected from monitoring wells MW1-MW5 and MW7-MW12. During the sampling event free product was detected in monitoring well MW6. Due to the presence of free product, monitoring well MW6 was not sampled during the event. Free product recovery was begum immediately. Analytical results for the collected groundwater samples revealed petroleum-type contaminants in excess of the 2L Standards in monitoring wells MW1, MW3, MW4, MW5, MW7, MW10, MW11, and MW12. 9/22/94 Incidences that occurred at the Beroth bulk facility and the adjoining Jonesville Amoco station were merged into a single file, referred to as Jonesville Amoco-B and assigned PIRF #12118. 10/12/94 Following the discovery of fuel oil (free product) in monitoring well MW6, three soil samples (FOL1-FOL3) were collected from beneath the fuel oil product lines (UST located adjacent to the former 10,000-gallon gasoline USTs). Analytical results for the collected soil samples revealed TPH violations ranging from 5,760 ppm – 7,670 ppm for 5030 and 7,770 ppm – 11,800 ppm for 3550. 10/21-12/12-94 An automated recovery system was installed on monitoring well MW6 and a total of 2,000-gallons of fuel oil and fuel oil/water mixture were recovered from monitoring well MW6. The monitoring well was monitored for the presence of free product every two (2) weeks beginning on December 12, 1994. Free product was not detected until April 11, 1995, when approximately two (2) inches of free product was detected. The automated system was restarted and an additional 1,280 gallons of fuel oil/water was removed from the well. 11/7-8/94 Three borings (B6-B7) were advanced around the perimeter of the fuel oil UST field. Borings were also advanced to collect deep soil samples in the vicinity of the gasoline product lines and dispenser islands.

The CAP stated the most cost-effective means of remediation was a combination of air sparging/soil vapor extraction and pump and treat. 5/24/96 A Groundwater Monitoring Report was submitted by GeoScience & Technology, P.A. The monitoring report documented groundwater sampling events that occurred in 1995. 7/17/96 A letter from NCDEHNR indicated that Senate Bill 1317 (ratified June 21, 1996) required that all UST-related contamination incidents be ranked according to the Section’s revised Site Priority Ranking System. The site was issued a priority ranking score of E 080. Under SB 1317 cleanup at the site was temporarily suspended. 12/4/98 A letter from NCDENR states that in accordance with the risk criteria rules adopted by the Department on January 2, 1998, the site should be reclassified to an Intermediate Risk. Based upon the new classification NCDENR requested the completion of a CSA Addendum. 2-3/99 A receptor survey was completed for properties within 1,500 feet of the release area. Results of the receptor survey revealed one water supply well (Martin Well) was located approximately 450 feet downgradient of the site. The well was identified as out of service. 2/11/99 Seven soil borings were advanced at the site in locations where previous assessment had occurred. The purpose of these borings was to assess areas of soil contamination using risk based sampling methods. Collected soil samples were analyzed by Methods 8260 and MADEP VPH. Methods 8270 and MADEP 8270 were included where necessary. Analytical results for the collected soil samples revealed the presence of petroleum-type contaminants at concentrations in excess of both the soil-to-groundwater and residential-MSCCs. 3/2/99 Groundwater samples were collected from monitoring wells MW2-MW5, MW7-MW10, MW12, and MW13. Monitoring wells MW1 and MW6 were not sampled due to the presence of free product. Monitoring well MW11 could not be accessed due to a car parked on top of it.

Specifically, Terraquest is requested to provide a detailed explanation on: “Has any remediation been done at the site? If yes, what has been done to remove free product…excavation?…MMPE? (how may events?)…Other? What has been the cost? Has it been effective? Why do you think that it has/has not been effective? Please give numbers to justify that the present course of action is not working…cost, thickness of free product through time, extent of the free product plume (increasing, decreasing, stable). The UVOST would be focused on soil. What do the soil contaminant levels look like? Please provide the cross-sections and figures that outline soil contamination above the residential standards. Do you think that free product may exist in areas that have not been assessed such as under the water table?...in the smear zone?” 100 East Ruffin Street, Mebane, North Carolina 27302 Telephone (919) 563-9091 ·Facsimile (919) 563-9095 www.terraquestpc.com Page 15 of 15 8/12/20 Terraquest submitted a Site Status Report, that answered the questions posed by the NCDWM-UST in their August 11, 2020 email. 9/24/20 The NCDWM-UST requests that: “As the last sample event occurred just over a year ago in July 2019, I think the UST group can review the site for a feasibility study.

Receipt The samples were received on 3/7/2022 9:25 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 2.1º C. Receipt Exceptions One of the 40 mL VOA vials for each of the following samples was received broken: MW5 (400-216556-1), MW21 (400-216556-14), and MW25 (400-216556-18). There was sufficient sample to perform the requested analysis. GC/MS VOA Method SM6200-B: The matrix spike / matrix spike duplicate (MS/MSD) precision for analytical batch 400-569211 was outside control limits. Sample matrix interference is suspected. Method SM6200-B: The continuing calibration verification (CCV) associated with batch 400-569211 recovered above the upper control limit for Ethanol. The samples associated with this CCV were non-detects for the affected analyte; therefore, the data have been reported. Method SM6200-B: The laboratory control sample (LCS) for analytical batch 400-569211 recovered outside control limits for the following analytes: 2-Hexanone, 4-Methyl-2-pentanone (MIBK) and Ethanol. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method SM6200-B: The following samples were diluted to bring the concentration of target analytes within the calibration range: MW5 (400-216556-1), MW10 (400-216556-5), MW11 (400-216556-6), MW20 (400-216556-13), MW23 (400-216556-16) and MW24 (400-216556-17). Elevated reporting limits (RLs) are provided. Method SM6200-B: The matrix spike duplicate (MSD) recoveries for analytical batch 400-569211 were outside control limits. Sample matrix interference is suspected. Method SM6200-B: Due to the high concentration of Ethanol, the matrix spike duplicate (MSD) for analytical batch 400-569211 could not be evaluated for accuracy and precision. The associated laboratory control sample (LCS) met acceptance criteria. Method SM6200-B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 400-569376 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected. Method SM6200-B: The following samples were diluted to bring the concentration of target analytes within the calibration range: MW27 (400-216556-19) and MW30 (400-216556-20). Elevated reporting limits (RLs) are provided. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. VOA Prep No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

Receipt The sample was received on 3/15/2022 9:27 AM. Unless otherwise noted below, the sample arrived in good condition. The temperature of the cooler at receipt was 18.2º C. Thermal preservation is not performed for air samples. GC VOA Method EPA-18: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 400-570192 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. Method EPA-18: The following sample was diluted to bring the concentration of target analytes within the calibration range: MMPE SVE (400-216968-1). Elevated reporting limits (RLs) are provided. Method EPA-18: The matrix spike / matrix spike duplicate (MS/MSD) precision for analytical batch 400-570192 was outside control limits. Sample matrix interference is suspected.

The site’s location, vicinity, and layout are depicted on Figures 1, 2, and 3. The test reveals how the subsurface responds to vapor extraction. Data is used to evaluate the suitability of the site for SVE and to design a full-scale SVE system. On April 13, 2022, Terraquest performed SVE testing using SVE pilot test well SVE3 and also monitoring wells MW6, MW15, MW16, MW26, and RW1. Terraquest personnel supervised the construction of SVE well SVE3 on March 1, 2022. The well was installed in preparation for the pilot test. Other wells were pre-existing as part of prior assessment. Soil Vapor Extraction Pilot Test Report For: Jonesville Amoco B, 428 N Bridge St, Jonesville, Yadkin County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: April 13, 2022 Report Prepared: July 202, 2022 2 Site Hydrogeology The subject property is located in the Sauratown Mountains and Anticlinorium of the Inner Piedmont Belt of the Piedmont Physiographic Region of North Carolina. Generally, gently rolling, well rounded hills and long low ridges are found throughout the Piedmont Physiographic Region. Groundwater in the region is directed toward the Yadkin River to the north. According to the Geologic Map of North Carolina (Brown, 1985), the area is underlain by metagraywacke, amphibolite, and kyanite schist. The Yadkin River is the dominant surface water body in the vicinity of the site. Cobb, Beaverdam, Jonesville, Sanderberry, and Fall Creeks are all located on the south side of the Yadkin River where they discharge. In the site’s vicinity, Elkin, Dutchman, and Turkey Creeks arrive at the River from the north. The following lithologies were encountered at the site during the various stages of assessment: 0’- 6' BGL Silt (ML) Mostly soft to medium stiff tan/orange silt, with few clay. 6’- 18' BGL Clayey Silt (ML) Mostly medium stiff tan/reddish-orange clayey silt. 18’- 44' BGL Saprolite Weathered bedrock with characteristics of overlying regolith soils. 44’- 61' BGL Bedrock Soil Vapor Extraction Pilot Test Report For: Jonesville Amoco B, 428 N Bridge St, Jonesville, Yadkin County, NC Prepared by: Terraquest Environmental Consultants, P.C.

Test Date: April 13, 2022 Report Prepared: July 202, 2022 4 Soil Vapor Extraction Pilot Test Report For: Jonesville Amoco B, 428 N Bridge St, Jonesville, Yadkin County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: April 13, 2022 Report Prepared: July 202, 2022 5 Historical groundwater flow at the site decreases to the north, northwest toward Yadkin River. The water table fluctuates with historical average shallow aquifer mins and max depth to water measurements ranging 15 to 33 feet BGL. The groundwater elevation measurements reveal that the hydraulic head within the shallow phreatic aquifer ranged from a relative value of approximately 84.73 feet at monitoring well MW”4” to 65.95 feet at monitoring well MW11 as measured on July 19, 2012. As measured parallel to groundwater flow, these results and others averaged across the site, indicate flow in the phreatic aquifer is in a north-northwesterly direction under an average hydraulic gradient of 0.02 – 0.04. To provided preliminary estimates of hydraulic conductivity (K) and groundwater flow velocity (v) for the phreatic aquifer, Terraquest personnel performed slug tests on monitoring wells MW7, MW15, and MW16 on July 19, 2012. Hydraulic conductivity estimates were determined using Aquifer Test Pro 2010.1, a computer model developed by Waterloo Hydrogeologic. The data was reduced using the Bower and Rice Method. The preliminary hydraulic conductivity estimates range from 0.154 to 0.725 feet per day. These values for hydraulic conductivity fall within the range expected of silt to silty sand. Terraquest used a hydraulic conductivity of 0.2 feet per day that is weighted more toward the K for monitoring wells MW7 and MW16. The lithologies logged in the saturated zones of the slug tested monitoring wells support this. Using an average hydraulic conductivity value of 0.2 feet per day, an average groundwater seepage velocity value was determined to be 0.04 feet per day or 15 feet per year. An effective porosity of 0.15 and a hydraulic gradient of 0.02 (based on 7/19/12 data) were used for calculating the groundwater flow velocity.

Test Date: April 13, 2022 Report Prepared: July 202, 2022 6 General applicability based on soil type and contamination: The following chart presented as Exhibit II-4 from the EPA publication entitled “How to evaluate alternative cleanup technologies for underground storage tank sites,” depicts the ranges of intrinsic permeability for various soil types and the effectiveness of SVE on those soils contaminated with various petroleum products. Based on permeability and the contaminants, the site is generally suitable for implementation of SVE. US EPA. 1995.

Soil Vapor Extraction Pilot Test Report For: Jonesville Amoco B, 428 N Bridge St, Jonesville, Yadkin County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: April 13, 2022 Report Prepared: July 202, 2022 7 GENERAL PROCEDURES Terraquest performed several SVE tests on April 13, 2022. One test was conducted using SVE3 as the extraction point, one using RW1 as the extraction point, and one using MW26 as the extraction point. The basic test procedure consisted of applying a vacuum to the extraction well while monitoring pressure response at other points of varying distance and direction from the extraction point. Vacuum pressure and air flow at the extraction well were also monitored. A GAST regenerative blower with a 1.5 hp electric motor was used to create the vacuum. Various pressure and flow gauges were also used. The blower and gauges were connected with air-tight seals to the various points to minimize leakage and, thus, systematic error. During the first test, a vacuum was applied and steadily increased to full power on extraction well SVE3. Observations were made at nearby wells MW6, MW15, MW1, and MW26. After 15 minutes of full vacuum with very little flow from the exhaust stack, no influence was seen at any of the wells. Similar lack of influence was seen during the second test conducted using RW1 as the extraction point. During a third test, vacuum was applied at monitoring well MW26. Some influence was seen at RW1 during that test. These were all short-term air permeability tests used to calculate the vadose zone permeability to air flow (intrinsic permeability). The second type of test performed was a steady state test. During this test, extraction was continued at MW26 while monitoring response at RW1 was recorded. The steady state tests last from approximately 1 hour to several or more days, depending on the objectives of the test, the scale of the project, and other cost justification factors. Two or more tests may be conducted at various extraction well flow rates. A relationship between applied vacuum and vapor flow yield is developed from these tests. This relationship is used for blower selection in the design of the full-scale system. Data from these tests can also be used to calculate intrinsic permeability. Soil Vapor Extraction Pilot Test Report For: Jonesville Amoco B, 428 N Bridge St, Jonesville, Yadkin County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: April 13, 2022 Report Prepared: July 202, 2022 8 For tests of sufficient length, it may also be possible to establish VOC mass removal rates by measuring the steady state vapor concentrations in the off gas. To achieve steady state, at least one pore volume of vapor must first be removed. It is not usually possible during the test to know exactly when this occurs. One indication is a leveling of vapor concentrations after a significant decline. This change occurs as all stagnant air is purged from the capture zone. SPECIFIC PROCEDURES AND RESULTS As stated, Terraquest personnel conducted three air permeability tests on April 13, 2022 with some success at only one of them. Tests were conducted as follows: TEST 1: Well identification Radial distance (feet) from extract point Screened interval (feet) Total depth (feet) Well diameter (inches) SVE3 0: extraction here 15-25 25 2 MW6 10 20-35 35 2 MW15 42 15-35 35 2 MW16 19 15-35 35 2 MW26 16 15-35 35 2 RW1 27 10-45 45 4 For Test 1, despite the application of full vacuum at SVE3, no influence was seen at any of the other wells following 15 minutes. There was very little flow from the exhaust stack indicating a lack of influence and connectivity, and a strain on the vacuum regen blower used.

As shown on the attached analytical report, no petroleum-type vapors were present at concentrations above of the laboratory’s method detection limit. DATA ANALYSIS AND CONCLUSIONS Based on the pilot test conducted by Terraquest personnel, the site does not appear to be acceptable for SVE as a remedial method. While a small amount of influence was seen in one well, most wells did not have any influence. This indicates a level of heterogeneity that will not allow SVE to work as it is intended. At this time, a low vacuum SVE system is not recommended.
