This work is related to a release from a previous gasoline UST system. The NCDWM-UST requested the work that included pilot testing, calculations, and considerations of active and passive remedial methods. In consideration of the contamination present and treatment methods investigated, Terraquest recommends SVE and air sparging as active treatment methods for the Perth Mini Mart release incident. Both methods proved practical during pilot testing. Terraquest roughly estimates that 3- 4 years of operating an SVE and air sparge remediation system followed by a year of monitored natural attenuation could allow closure of this site in 2028 at a cost of $525,000. If the NCDWM- UST agrees, the next step is to generate a CAP Corrective Action Design Report.

This work was requested by the NCDWM-UST and costs were pre-approved on ePATA 40784-014. 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 2.1 UST Owner: The USTs are owned by Madhukunj, LLC. 2.2 Tank and Release Information: According to the NC UST Database Records, two 6,000-gallon gasoline, one 4,000-gallon gasoline, and one 2,000-gallon diesel USTs were installed at the site on March 4, 1980. Note that the 2,000-gallon diesel UST was converted to non-ethanol gasoline in 2018. A 2,000-gallon diesel AST is also present onsite. The installation date of that tank is unknown. All USTs were closed via excavation and removal in February 2019 as previously reported. Following closure, two new 12,000-gallon, gasoline, compartmentalized USTs were installed. A site history of the USTs and AST on the property is included as Table 1. Previous tank locations are shown on Figure 3. In 2017, the UST owner noted inventory record discrepancies based upon ATG reading for UST T3, the 4,000-gallon gasoline tank. In response, the UST owner submitted an UST-17A UST Suspected Release 24-Hour Notice Form. The date and nature of the release is unknown but CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 2 Troutman, Iredell County, NC inventory records show a shortage of approximately 300-400 gallons. Based on the lab results of soil samples from beneath the other two gas USTs in the T3 basin, a release occurred from those tanks also. Terraquest is not aware of any AST release incidents. The site and several properties in the area are commercial in nature with the remaining majority used as residential as shown here: SITE CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 3 Troutman, Iredell County, NC The closest residence is located approximately 330 feet north of the release area. There are no places of public assembly within 1,500 feet. Land use in the vicinity of the site is highway business and residential. The site and properties to the east are zoned Highway Business (HB). Most of the remaining properties are zoned Residential (RS). Zoning classifications of the site and surrounding properties are depicted on Figure 2 and below as taken from Iredell County’s GIS online system at https://iredell.connectgis.com. Environmental assessment activities were previously detailed in a Site Check Report, LSA Report, and CSA Report sent to the NCDWM-UST. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 4 Troutman, Iredell County, NC 2.3 Receptor Information As part of the LSA and to determine the risk classification of the site, Terraquest personnel previously performed a reconnaissance of properties within a 1,500-foot radius of the source area. The reconnaissance effort consisted of obtaining tax department and local zoning information on properties and conducting door-to-door visits of certain properties within 1,500 feet of the source area, in addition to collecting other pertinent information from the appropriate local and state officials. Terraquest personnel inspected all properties within 1,500 feet of the site and attempted to contact all the property owners within 1,000 feet in person. Property owners within a 500 -foot radius were questioned, if available, as to the source of their water and if any water supply wells were located on their property. If owners/occupants were not home, a survey form was left at their residence or forwarded to the property owners through the mail. In all cases, Terraquest also conducted a visual survey of the property. Table 2 lists the names and addresses of surrounding property owners. Note that the PIN Numbers presented in Table 2 correspond with those shown in Figure 2. Terraquest contacted the Town of Troutman’s Public Works Department to inquire about the Town’s water supply system. Terraquest was put into contact with West Consultants, PLLC, who maintains and operates the municipal supply system. Todd Poteet of West Consultants, PLLC, verified water lines are available along Perth Rd. and Autumn Leaf Rd.; however, not along Weddington Ln. Furthermore, since the subject area is not located within the jurisdictional boundary of the Town of Troutman, property owners are not required to connect to the municipal water supply system. Most are not interested in doing so as they would be annexed into Troutman and its associated taxes. Through the reconnaissance efforts, a total of thirty-three water supply wells were identified within 1,500 feet or the source area. Of those identified wells, nineteen are sole source water CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 5 Troutman, Iredell County, NC supply wells located within 1,000 feet. One additional active water supply well is located on the site within 250 feet of the source area. That well is used to fill minnow tanks at the store. Water supply well information is listed in Table 3. Supply well locations are depicted on Figure 2. As part of the reconnaissance effort, Terraquest also searched for any surface water bodies within a 500-foot radius of the site. An unnamed tributary of Big Branch originates off the western property boundary of the site and is located within 500 feet of the source area. The NC Division of Water Quality (DWQ) classifies Big Branch as a Water Supply-IV “Waters used as sources of water supply for drinking, culinary, or food processing purposes.” The unnamed tributary of Big Branch is depicted on Figure 2. 2.4 Regional Geology and Hydrogeology The site is in the Piedmont Physiographic Region of North Carolina. According to the Geologic Map of North Carolina (Brown, et al, 1985), the site is in the Charlotte Belt and is underlain by mafic metavolcanic bedrock lithologies. On a regional scale, the Piedmont is characterized by land with moderate relief and some areas of low relief hills and valleys. Groundwater in the region is part of the Catawba River Basin. Regionally, groundwater flows to the southwest and feeds into Big Branch Creek and ultimately Lake Norman. Big Branch Creek is listed as a Water Supply IV surface water body at https://deq.nc.gov/about/divisions/water- resources/planning/classification-standards/classifications#DWRPrimaryClassification which classifies surface water bodies with a WSIV classification as “sources of water supply for drinking, culinary, or food processing.” CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 6 Troutman, Iredell County, NC The site’s location in reference to nearby water bodies as provided by the NCDEQ at https://ncdenr.maps.arcgis.com/apps/webappviewer/index.html?id=6e125ad7628f494694e25 9c80dd64265 follows: SITE SITE CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 7 Troutman, Iredell County, NC 2.5 Site Geology and Hydrogeology ENCOUNTERED LITHOLOGY The following lithologies were encountered at the site during the installation of soil borings and the monitoring well network: 0 – 63’ BGL SILT (CL) Mostly soft to medium-stiff (generally increasing consolidation with depth), micaceous, red to brown to tan, with trace clay and characteristics of saprolite in areas. 63-70’ BGL SAPROLITE Mostly tan/brown heavily-weathered rock. The drilling locations of the monitoring wells used to describe the lithology are depicted on Figure 3. Geologic cross sections of the site are based upon the soil boring logs are as follows: CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 8 Troutman, Iredell County, NC CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 9 Troutman, Iredell County, NC CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 10 Troutman, Iredell County, NC Depth-to-water measurements have been collected from the monitoring wells during various stages of the assessment to estimate the direction of groundwater flow. Groundwater elevation measurements were reduced to a common datum by surveying the relative elevation of the top of the casing for each monitoring well. The water table elevation data as measured on November 23, 2021 was used to create a potentiometric surface map which illustrates the interpreted direction and gradient of groundwater flow that is generally to the west, southwest. Recent groundwater elevation data and monitoring well construction information is provided in Table 4. Historical groundwater elevation data is provided in Appendix C. The groundwater elevation measurements from April 30, 2019 reveal that the hydraulic head within the shallow phreatic aquifer ranged from a relative value of 66.61 at monitoring well MW5 to 67.91 at MW4. In conjunction with other site measurements, the results indicate flow in the phreatic aquifer in a south/southwest direction under an average hydraulic gradient of approximately 0.02. Water level data from the Type III monitoring well (MW11) and the interpreted groundwater elevation in the phreatic aquifer in the vicinity of the Type III well (based on MW5) were used to determine if a vertical head gradient existed in the phreatic aquifer. The vertical head gradient was calculated using the following equation and groundwater elevation data collected on April 30, 2019: Vg =�ℎ𝑝𝑝ℎ𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟−ℎ𝑀𝑀𝑀𝑀11�𝐷𝐷 where: Vg = Vertical head gradient Hphreatic = Water elevation in the shallow aquifer = 66.61’ HMW= Water elevation in deep well MW11 = 66.85’ D = The difference in elevation between the shallow water table and the middle of the well screen in MW11 = (66.61 – 29.3) = 37.31’ CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 11 Troutman, Iredell County, NC Vertical head gradient: 𝑉𝑉𝑔𝑔=66.61 −66.8537.31 = -0.0064 The head gradient suggests a value very near zero indicating that it is transition zone between a recharge and discharge area. This seems reasonable as the site is located near Lake Norman where local groundwater and surface water are discharging to. To provide preliminary estimates of hydraulic conductivity (K) and groundwater flow velocity (v) for the phreatic aquifer, Terraquest personnel performed slug tests on monitoring wells MW3, MW5, and MW7 on December 3, 2018 as part of the CSA. The preliminary hydraulic conductivity estimates range from 0.176 to 0.427 feet per day. Using an average hydraulic conductivity value of 0.336 feet/day, an average groundwater seepage velocity was determined to be 16.35 feet per year. An effective porosity of 15 percent was chosen based on published values of effective porosity for silt with the value skewed toward silty sands based on a silt range of 3-19 percent and a silty sand range of fine to silty sand of 10-28 percent (Sanders, 1998). An average hydraulic gradient as measured on December 3, 2018 across the site was used. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 12 Troutman, Iredell County, NC 2.6 Local Topography The local topography is characterized by gently rolling, well rounded hills and long low ridges with a few hundred feet of elevation difference between the hills and valleys. The majority of the surrounding 1,000 feet of the site is mapped at approximately 800-900 feet above sea level. Local topography is depicted in Figure 1. 2.7 Land Cover/Surface Drainage The release area is currently overlain by asphalt as shown below. The property slopes to the west, southwest behind the store where there are grass/gravel areas that precipitation can infiltrate the ground. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 13 Troutman, Iredell County, NC 3.0 UPDDATE OF SITE ASSESSMENT INFORMATION 3.1 Soil Assessment Through the 2017 Site Check, 2018 LSA, the 2019 UST closure, the 2019 over-excavation, and the CSA, a total of fifty-seven samples were collected to delineate the extent of soil contamination. The area of STG MSCC violation is generally centered on the UST basin with a smaller area around the northern dispenser island. The volume of contamination is a sum of these two areas. With an average depth to water of 31 feet in monitoring wells near the UST basin in April 2019, the calculated tonnage at the site includes 1,220 tons near the basin and 15 tons at the northern dispenser area. The area is shown here: CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 14 Troutman, Iredell County, NC Note that Terraquest had discussions with the NCDWM-UST in 2019 prior to and during the UST closure regarding further excavation of contaminated soil as it was exposed and readily available to dig out. Ultimately, the Trust Fund did not authorize additional excavation. The RP chose to dig out an additional 94.66 tons in the southwest direction from the UST basin as it extended away in the direction where over six feet of product has been gauged. The limits of excavation in the sloping direction of product flow were all still above the STG MSCCs including some material that could have been excavated that was above the Residential MSCCs. Again, Terraquest’s request to dig this material out was denied. 3.2 Groundwater Assessment 3.1.1 Monitoring Well Network Throughout various phases of assessment, a total of seventeen monitoring wells have been installed to delineate groundwater quality. Those wells include sixteen Type II wells and one Type III telescoping deep well. The well locations are shown on Figure 3, their construction is detailed on Table 4. 3.1.2 Groundwater Sampling The latest groundwater monitoring event was conducted on September 23, 2020 when Terraquest personnel sampled monitoring wells MW1, MW3-15, and MW17. Monitoring wells MW2 and MW16 contained free product and were not sampled. Prior to sampling, Terraquest field personnel purged at least three well volumes of 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 Trust Fund, all wells were also sampled for 625 targeting SVOCs. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 15 Troutman, Iredell County, NC The analytical results of the sampling events reveal an oval-shaped plume that begins at the northern dispenser island UST basin and extends downgradient past monitoring wells MW12 and MW13. The 2L Standard violation plume, applicable to this High Risk site, measures 180 feet long by 100 feet across at the widest point and covers an area of 13,600 square feet. That is an increase in size from the 2018/2019 CSA data where the 2L Standard violation plume covered 11,300 square feet. The increase is due to the appearance of 2L Standard violation in monitoring wells MW10 and MW12 and the increase in contaminant concentration in monitoring well MW7. Further details of the results follow: Free product: MW2 (4.12’) MW16 (0.05’) >GCL: MW3, MW5, MW15, MW17 > 2L Standards: MW1, MW4, MW6, MW7, MW8, MW10-13 <2L Standards: MW9, MW14 MW15 and 17 have since had free product present CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 16 Troutman, Iredell County, NC 3.3 Free Product Assessment and Recovery 3.3.1 Discovery: Prior to developing monitoring wells MW2 – MW4 on June 19, 2018, monitoring wells were visually checked for the presence of free product with a bailer prior to their development. At that time, free product was observed in monitoring well MW2. Product was subsequently discovered in monitoring well MW16 on September 23, 2020, monitoring well MW17 on March 22, 2021, and in soil vapor extraction (SVE) well SVE3 on November 22, 2021. 3.3.2 Free product pictures MW2 10/7/19: MW2 7/24/19: MW2 4/22/19: CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 17 Troutman, Iredell County, NC Free product pictures continued: MW16 9/23/20 DTW 29.15’ MW16 11/23/21 DTW 34.82’ CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 18 Troutman, Iredell County, NC 3.3.3 Historic product presence: MW2 7.05 feet in October 2018 prior to MMPE 5.63 feet two months after MMPE in December 2018 4.11 feet in April 2019 before MMPE and following a one-foot water table increase 0.05-foot thickness following the April 2019 MMPE 0.18 feet four days after April 2019 MMPE and rising 4.12-foot product thickness on September 23, 2020 3.08-foot product thickness on March 22, 2021 prior to MMPE No product on April 21, 2021, a month after MMPE 4.2-foot thickness prior to air sparge pilot test on November 23, 2021 MW15 3-foot thickness prior to air sparge pilot test on November 23, 2021 MW16 0.05-foot product thickness on September 23, 2020 2.85-foot product thickness on March 22, 2021 prior to MMPE 1.49-foot product thickness on April 21, 2021, a month after MMPE MW17 0.12-foot product thickness on March 22, 2021 0.05-foot product thickness on April 21, 2021, a month after MMPE SVE3 0.1-foot thickness prior to pilot test start Historical groundwater elevations and product thicknesses are detailed in Appendix C. 3.3.4 Recovery events: MMPE events have been conducted for this release incident as authorized on ePATAs 40784-002, -007, and -013. All the events were five days in length. MMPE services were provided by Zava Industrial, Inc. for the October 2018 event and by EarthX, Inc. for the April 2019 and March 2021 events. The October 2018 event was successful in removing 4,041 gallons of liquid, the April 2019 event recovered 3,461 gallons, and the March 2021 event recovered 4,679 gallons. Emissions of 56.86 gallons, 64.23 gallons, and 20.72 gallons were reported for the three events, respectively. Additional MMPE events were denied by the NCDWM-UST. 3.3.5 Free product delineation: Following a high-resolution study conducted in June 2020 by Dakota Technologies Company, LLC, additional monitoring wells MW15, MW16, and MW17 were installed by an NC-licensed driller on September 22-23, 2020 at previously selected locations validated by the high-res data. Their CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 19 Troutman, Iredell County, NC locations around MW2 are shown on the enclosed Figure 3. Table 4 shows well construction details. The screen intervals were extended above the water table on all three wells to capture the product at shallower depths in accordance with typical well construction policy. The high-resolution study identified higher concentrations within the analyzed area as follows: CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 20 Troutman, Iredell County, NC 3.3.6 Product locations and water table fluctuations: As apparent from water table fluctuations and data from the high resolution study, several areas of free product are present vertically at the site. Greater product thicknesses were noted when the water table is lower. The majority of free-phase product is located 30 to 40 feet BGL. Supporting information is as follows: Date MW2 Free Product Thickness (feet) Groundwater Elevation (feet) 6/25/2018 6.25 61.95 10/22/2018 7.05 62.60 12/3/2018 5.63 63.68 4/22/2019 4.11 66.83 7/24/2019 2.85 67.06 9/23/2020 4.12 67.11 3/22/2021 3.08 69.56 9/23/2021 4.2 66.08 0 1 2 3 4 5 6 7 8 60.00 62.00 64.00 66.00 68.00 70.00 MW2 Free Product Thickness (feet) CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 21 Troutman, Iredell County, NC 3.3.7 Free product evaluation: On September 23, 2020, Terraquest personnel used a disposable bailer to remove product from monitoring well MW2 and subsequently record the rate of its return as requested by the NCDWM-UST. Personnel bailed product from an initial thickness of 4.12 feet at static conditions to a thickness of 0.25 feet that repeatedly showed up through several bails. As product was bailed from the well, it was temporarily placed into a 5-gallon bucket at the well. When that bucket filled, the contents were transferred to a transport can during which time the well would fill back up with 6-8" of product. Complete removal of the product was not possible. In total, over six gallons of product were removed through the efforts and later disposed of offsite in an environmentally-sound manner. In summary, those efforts amount to a six-gallon recovery via hand bailing in half an hour.

Without an alternate water source, there is no way to downgrade the risk. The cleanup objectives are the STG MSCCs for soil and the 2L Standards for groundwater. The corrective actions proposed herein are structured to meet those standards as the objective. Note that once free product and GCL violations are removed, it may be possible to conduct groundwater modeling to calculate alternate cleanup standards that are above the 2L Standards but do not threaten receptors. 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 Following removal of the UST system, Terraquest requested pre-approval of costs necessary to excavate contaminated soil. This request was denied. The method has the benefit of immediate removal of the source zone but can be costly. The current presence of a new UST system would require removal and replacement costs that negate this as a valid method. MMPE Mobile Multi-Phase Extraction (MMPE) events have been performed at this site with success. However, the cost associated with the events becomes prohibitive in comparison to other remedial options due to the volume of product remaining. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 23 Troutman, Iredell County, NC 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. Natural Attenuation Natural attenuation of the release incident would take a very long time and gives no protection to sensitive receptors. The presence of several feet of product would likely take decades to abate. 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, comparably, 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 an option without first removal of the current UST system, a cost that would remove this as an option. 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 and Dual-Phase Extraction Pump and treat and dual-phase extraction systems would effectively remove free product and dissolved-phase groundwater contamination. These methods are generally costly as they have multiple equipment components and require a large amount of maintenance and adjustments to operate well. The lack of any discharge options for the treated water is problematic as is the high capital and operations costs. While the methods provide hydrodynamic control of the area that offers protection to sensitive receptors, they are more costly than other options. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 24 Troutman, Iredell County, 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. 5.2 Pilot Testing Following discussion, agreement, and pre-approval of costs from the NCDWM-UST, Terraquest personnel installed wells and conducted SVE and air sparge pilot testing in November 2021. On November 16-17, 2021, Terraquest personnel supervised the installation of SVE pilot test wells SVE1, SVE2, and SVE3 and air sparge pilot test well AS1 at the locations shown on the attached Figure 3. SVE wells SVE1 and SVE2 were installed near the former UST basin to investigate SVE response for contaminated soil in that area. SVE well SVE3 was installed within the free product plume as was air sparge well AS1, at the request of the NCDWM-UST, to investigate free product recovery and air sparge effectiveness. All wells were installed using a Geoprobe Model 7822DT operated by an NC-licensed driller. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 25 Troutman, Iredell County, NC The SVE wells were constructed of 20 feet of 2”-diameter, Schedule 40 PVC casing attached to 15 feet of 2”-diameter, Schedule 40 PVC screen with a 0.010” slot size for a total well depth of 35 feet. This screen interval takes into consideration the prior depth of excavation, the location of the wells in relation to the source area, and the depth to water. The air sparge well AS1 was constructed of 55 feet of 1”-diameter, Schedule 40 PVC casing attached to 5 feet of 1”-diameter, Schedule 40 PVC screen with a 0.010” slot size for a total well depth of 60 feet. This screen opening forces the introduced air to spread throughout the aquifer where it can provide treatment. The wells were surveyed into the network following installation. Well construction information is further detailed in Table 4 and the well records are provided in Appendix D. SVE and air sparge pilot testing is detailed in reports provided in Appendices E and F. The tests and results are summarized hereinafter. 5.2.1 SVE Pilot Test Terraquest performed one true SVE test within the vadose zone near the former UST basin where the largest contaminated soil mass exists (SVE1) and a second test above the free product area during the air sparge test (SVE3). The tests were conducted on November 22 and 23, 2021, respectively. Testing at SVE1 was the chief set of tests with SVE3 conducted to verify those results by ensuring radius of influence was about the same, and to collect information for the sparge test that was conducted at the same time. 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. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 26 Troutman, Iredell County, NC Two types of SVE tests were conducted at SVE1: The first type of test conducted was an air permeability test that typically lasts for approximately 10 minutes. Vacuum was applied to the extraction well and the pressure responses in various observation points were recorded with time. The data is used to calculate the vadose zone permeability to air flow (intrinsic permeability). Terraquest personnel conducted three air permeability tests on November 22, 2021. Tests were conducted using SVE1 as the extraction well, while SVE2, SVE3, and MW1 were observed in each of the respective tests. The second type of test performed was a steady state test. These 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. For the steady state test on SVE1, Terraquest applied a vacuum of -22 inches of water for a half-hour, -40 inches of water for a half-hour, -60 inches of water for a half-hour, and -70 inches of water for the last half-hour. Similarly, the steady state test using SVE3 as the extraction point while monitoring wells MW1, MW2, MW16, and MW17 was run at progressive dilutions of -22 inches of water for a half-hour, -40 inches of water for a half-hour, and -80 inches of water for a half-hour. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 27 Troutman, Iredell County, NC Air Permeability Terraquest used US EPA’s (1993) Hyperventilate program to evaluate the air permeability test data. Hyperventilate uses the transient pressure response in the observation point to calculate an air permeability value using a theoretical relationship developed by Johnson, et al (1990a). Hyperventilate results are attached in Appendix E. The estimated value of intrinsic permeability (k) for varying soil lithologies ranges from 10-1 (clayey silts) to 105 darcy (gravel) as shown in Appendix E’s Help-page 13 that supports page 8 of the Hyperventilate analysis. Terraquest chose to enter a darcy value range from 0.25 to 1 as it most accurately represented the flow ranges that were observed during the pilot tests. Radius of Extraction Well Influence The ROI was determined based upon data from the steady state test. A rule-of-thumb recommended by U.S. EPA (1995) is that the ROI will be the distance at which a vacuum of 0.1 inches of water is yielded. To determine this distance, Terraquest plotted vacuum pressure versus distance as shown in the graph that follows. When determining the point at which 0.1 inches of water is yielded, a straight-line relationship was drawn from the extraction point through the observation points in a best-fit manner. The graph shows a corresponding x-axis crossing of 23.5 feet. A 20-foot radius is chosen as a conservative estimate of influence that allows for some site heterogeneities.

The following values were constant throughout the calculations: (see card SD2 and 3) • permeability (k) of 0.25 to 1 darcy (previously discussed), • critical volume of air of 146.71 L/g (see card SD7), • extraction well efficiency of 30 percent (see card H29) • Average contamination concentration across subject area of 2,325 mg/kg (previously discussed), • Radius of test influence of 20 feet, • Cleanup time of three years (used as a rough estimate). The required number of wells calculated by Hyperventilate ranged from 1 to 11 based on area and critical volume calculations. The data does not consider site heterogeneities, the requirement of the SVE system to recover free-phase product and sparge vapors and is a rather large range. Site structures, cost, and installation feasibility must also be accounted for. In consideration of the aforementioned items, Terraquest recommends the use of ten SVE wells at the locations shown on the next page and on Figure 5. This includes use of the existing SVE1, SVE2, and SVE3 and the installation of seven new SVE wells. SVE Pilot Test Conclusions Based on the pilot test conducted by Terraquest personnel, the site is acceptable for SVE as a remedial method. SVE is recommended to remediate soil and remove free product and sparge exhaust vapors. Ten dedicated SVE wells are recommended.

During the air sparge test conducted on November 23, 2021, air was introduced into AS1 while measurements were collected from observation points MW1, MW2, MW15, MW16, and MW17. Air was supplied to the injection point from a portable, electric, oil-less air compressor powered by a portable electrical generator brought onsite for the test. The compressor output was connected to the injection point through a series of hoses, pipes, and fittings. Air flow into the injection point was measured with an adjustable flow meter. A static pressure gauge was installed downstream of the flow control valve. The change in depth to product and water in the observation points was measured using a Solinst Model 122 Interface Meter. The test consists of several stages in which a constant flow is applied, while the air pressure and water levels are measured. After groundwater mounding stabilizes, the flow is stepped up and held constant for another stage. The number of stages depends on the rate at which responses occur. During the November 23, 2021 test, a total of three different flow rates were applied to the air sparge well. Flows of 1.0, 1.5, and 2.0 standard cubic feet per minute were all applied. Those flow intervals were provided for 1 hour, 1.5 hours, and 1.5 hours, respectively. That is, 1.0 scfm was applied for the first 60 minutes, 1.5 scfm was applied from 60 to 180 minutes, and 2.0 scfm was applied from 180 minutes until test conclusion at 270 minutes. Measurements are provided in Appendix F. The three main objectives of data analysis are to determine whether air sparging is suitable for the site, determine a reasonable radius of influence for an air sparge well, and establish data for equipment selection in the design of a full-scale system. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 32 Troutman, Iredell County, NC Suitability The responses observed during the test indicate air sparging would be suitable for the site. Air was injected into the subsurface and flow was maintained. Some sites have had poorly installed air sparge wells where the screens are cemented or the lithology is too tight and air will not enter the saturated zone at all. This was not the case at the subject facility. The injection was made with a standard electrical air compressor suitable for short-term testing and flowable air was maintained without a large amount of pressure. Flowable pressure for the test was less than 20 psi and a larger spike for breakthrough pressure was not observed. While some breakthrough pressure exists, it was obviously within the limits of the operating equipment and was short-lived enough that field personnel did not see it. Radius of Influence Determining the radius of influence involves a study of the influence observed in the wells monitored during the pilot test. As the remedial method of air sparging is the mechanical stripping of contaminants from the dissolved phase into a liberated waste air stream, the extent of that effect is what is searched for. Air sparging also acts as a remedial method by increased the amount of oxygen dissolved in the surrounding aquifer and that should be analyzed too. However, the presence of free product prevented field measurement of DO with routine equipment and this data was not obtained. Prior to and throughout the test, the depth to water was measured in surrounding wells. As the test progressed, the water table was mounded by the applied air as seen at observations wells by a rise in the water table. In a fully evolved test with a sufficiently low air flow, the water levels will subside to near static levels after some period of time as the mounding is spread across the aquifer. When this drop occurs, the air flow rate is typically increased to the next step. The measured data is summarized in Appendix F and in less detail below in this text. These graphs show the mounding and subsequent stabilization of groundwater during each flow increase. The stabilization is slight and is realized by a tapering of water mounding in some cases. The evidence CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 33 Troutman, Iredell County, NC of these water level stabilizations is an important result, since it indicates that low flow sparging can be performed without causing sustained high water levels. These measurements also are indicative of the radius of influence of the air sparge well.

The radius is subject to hydrogeology and isn’t as simple as a straight-line graph. The data indicates mounding as far away as 34 feet. The goal is to calculate a ROI that provides air sparging to all areas without creating service gaps. The size, shape, and placement of the free product and dissolved-phase plume onsite where the sparging would occur also needs consideration. In consideration of all these factors, 20 feet is recommended as a working radius of influence. A total of seven air sparge wells is recommended and includes the existing well and six new sparge wells. Terraquest proposes the well placement as shown on Figure 6 and as follows that considers site layout, remedial goals, free product, GCLs, and radius of influence: 7 wells total 1 existing 6 new CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 36 Troutman, Iredell County, NC Design data The air sparge test achieved sustained flow up to 2 scfm at a pressure between 12 and 17 psi. Equipment should be sized for a flow demand of 7 wells at a flow rate up to 4 scfm each for a total of 28 scfm with some extra to allow for an increase in sparging as needed. Pressure over 17 psi was not observed but could have happened briefly as breakthrough was occurring. Air sparge breakthrough is typically 1 psi for every 2.3 feet of head (US EPA 1995). With a head of 55 – 32.13 = 22.87 feet, the entry pressure required is estimated at 9.94 psi. The lithology accounts for some of the additional pressure required. Overall, the flow and pressure is within the range of typical air sparge systems. Air Sparge Pilot Test Conclusions Based on the pilot test conducted by Terraquest personnel, the site is acceptable for air sparging as a remedial method. Seven dedicated SVE wells are recommended. 5.3 Chosen Remedial Methods Based on the factors discussed, Terraquest chooses SVE and air sparging as the remedial methods for this site. 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. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 37 Troutman, Iredell County, NC CONTAMINANT MASS: Soil contaminant mass: Based on a known mass of contaminated soil and known mass of smear zone, a mass of contaminant can be estimated using the known contaminant/mass values from laboratory results. Using an average contamination value of 2,325 mg/kg from assessment results and the previously stated 1,220 tons + 15 tons = 1,270 tons of contaminated soil/smear zone, the following calculations yield a soil contamination mass of 5,893 pounds. 2,325 mg/kg x (1,270 tons x (907.185 kg / 1 US ton)) = 2,325 mg/kg x (1,152,125 kg) = 2,678,690,625 mg of contamination 2,678,690,625 mg / 1,000,000 mg/kg = 2,679 kg 2,679 kg x 2.2 pounds/kg = 5,893 pounds Free-phase product mass: 325 ft2 x 2.5-foot average product thickness = 812.5 ft3 x 7.48 gal/ft3 x 6.25 lbs/gal = 37,984 pounds Dissolved-phase contaminant mass (GCL violation): 3,300 ft2 x (10 feet beyond bottom of 50 foot wells – DTW 32’ = 60-32=28) = 92,400 ft3 x 28.3 L/ft3 = 2,616,476.6 L of GCL water. Average GCL violation wells on 9/2020 = 72,730 ug/L. 2,616,476.6 L of GCL water x 72,730 ug/L x 2.20462e-9 ug/lbs = 419.5 pounds. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 38 Troutman, Iredell County, NC INITIAL REMOVAL RATE: SVE removal rate: In addition to the mass removal estimates provided in the Hyperventilate analysis, Terraquest also collected an air sample from the SVE pilot test exhaust stream that also requires consideration toward mass removal. During the SVE pilot test, Terraquest personnel filled a 1L Tedlar bag with a representative air sample from the exhaust stack. The results of lab analysis listed a TPH concentration of 5,070,000 parts per billion by volume (ppbv). Operational SVE system generally have exhaust readings in the 10,000-100.000 ppbv, so >5,000,000 is significant. Using published blower performance curves and the time of operation, the following 22.56 pounds / 3 hours removal rate is calculated: minutes bump test 15 air permeability test 1 15 air permeability test 2 15 air permeability test 3 15 steady state test 120 180 SVE: this model produces (scfm flow rate):100 scfm TPH concentration of vapors at stack:5,070,000 ppbv Volume of air removed is (flow in cubic feet per minute) x length of testing (in minutes)18,000 ft3 Volume of gasoline vapor removed is equal to air volume removed muliplied by the TPH concentration. Vol. air removed (ft3) x [TPH concentration of vapor (ft3 gasoline vapor/1E+09 ft3 air)]91 ft3 gasoline vapor Conversions: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.2,580 liters gasoline vapor Conversions: Therefore: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 lb/454 g) equals lbs. vapor 22.56 lb of gasoline At standard temperature and pressure, there are 22.4 liters of gasoline vapor per mole of gasoline. The molecular weight of carbon in gasoline is 89 g/mole. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 39 Troutman, Iredell County, NC SVE removal rate continued: Disregarding all other factors, mathematically, the removal rate of the pilot test would indicate that at 22.56 pounds / 3 hours, the 5,893 pounds of soil contamination would be gone after 784 hours of SVE system operation. That is, after 33 days. This value isn’t close to 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. A more likely time frame is 2-3 years.

As shown in the attached analytical report, that sample had a reported concentration of 10,100,000 parts per billion by volume of Total Petroleum Hydrocarbons as Gasoline Range Organics. Using the following calculations, the removal rate during the test was: 67.42 pounds/4.5 hours Expanding the initial removal rate against the mass of contaminant calculates as follows: 37,984 pounds + 419.5 pounds = 38,403.5 pounds / (67.42 pounds/4.5 hours) = 2,563 hours / 24 hours/day = 107 days. So, if a treatment system were installed that had removal rates like those of the pilot test, the contaminant mass would be removed in 107 days. However, this does not account for water OPERATING PERIOD:START: 11/23/21 11:37 AM END:11/23/21 4:07 PM AIR SPARGE CALCULATIONS (via SVE sample recovery) SVE: this model produces (scfm flow rate):100 scfm TPH concentration of vapors at stack:10,100,000 ppbv Volume of air removed in ft3 equals (flow)(1,440 min/d)(time in period)27,000 ft3 Volume of gasoline vapor removed is equal to air volume removed muliplied by the TPH concentration.

It also ignores the readily available contamination that is liberated by a virgin pilot test. At some point, air sparge liberation at similar sites has shown a drastic reduction in contaminant recovery as the system run time increases. Having several feet of free product available for removal may allow the “early and productive” stages of the sparge 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 107 days. A 4-5 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. Several years of treatment are anticipated to remove contamination to levels where natural attenuation can take over and the threat to sensitive receptors is lessened. Further refinement of treatment time will be understood as the system is operated. 5.5 Remedial System Operation and Maintenance Plan Terraquest proposes two, 8-hour visits per month to perform system O&M activities. Those activities will include maintenance as 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 SVE and air sparge system and lines to wells will be inspected/adjusted/recorded. The load and unload pressures of the sparge compressor should be verified and recorded. 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 SVE, 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. The belts and impellers will be inspected/adjusted/replaced as needed. System moisture will be dealt with along with automatic knockouts and filters, drums, systems thereto. Aftercoolers will be cleaned and CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 42 Troutman, Iredell County, NC 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. Downstream discharge coalescing filters and associated media and regulators will be inspected/cleaned/replaced. Flows, pressures, and operation of any associated product drum and/or oxidizer and appurtenances will be collected. 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 SVE system’s exhaust stack and lab analysis per method EPA18 targeting BTEX, MTBE, and TPH. 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. Knowing the aquifer’s pH, conductivity, dissolved-oxygen, and the amount of sulfates and nitrates will help steer the need for any additional treatments. CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 43 Troutman, Iredell County, NC 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), • 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. 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 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 and close enough to the 2L Standards to suspend CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 44 Troutman, Iredell County, NC 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 May 2028. While it is possible that this could be accomplished quicker, experience has shown that it will most likely take longer. 5.8 Rough Cost Estimate The supervised installation and operation of an SVE and air sparge treatment system with one year of monitored natural attenuation is expected to roughly cost $525,000. Costs are estimated on Table 5. This cost includes $7,000 for CADR, ROD, and public notification, $39,000 for remedial well installation, $145,000 for system installation, $259,000 for system O&M, $64,000 for groundwater monitoring, and $10,800 for public notice, NORP, and monitoring well abandonment toward closure as follows: CADR ROD Remedial well install Supervised treatment system installation Annual sampling: Sytem operations and maintenance (O&M): Closure: 523,767.50$ 38,914.50$ 144,476.00$ 64,035.00$ 258,542.00$ 10,800.00$ 5,500.00$ 1,500.00$ CAP Feasibility Report Perth Mini Mart By: Terraquest Environmental Consultants, P.C. 818 Perth Road Date: January 17, 2022 45 Troutman, Iredell County, NC 6.0 CONCLUSIONS / RECOMMENDATIONS In consideration of the contamination present and treatment methods investigated, Terraquest recommends SVE and air sparging as active treatment methods for the Perth Mini Mart release incident. Both methods proved practical during pilot testing. Terraquest roughly estimates that 3-4 years of operating an SVE and air sparge remediation system followed by a year of monitored natural attenuation could allow closure of this site in 2028 at a cost of $525,000. If the NCDWM- UST agrees, the next step is to generate a CAP Corrective Action Design Report. 7.0 LIMITATIONS This report is limited to the investigation of petroleum-type compounds, and does not imply that other unforeseen adverse impacts to the environment are not present at the facility.

APPENDIX A Page 1 of 8   TECHNICAL METHODS/STANDARD PROCEDURES    Equipment Decontamination    All soil sampling equipment utilized during site assessment activities is decontaminated according  to standard and accepted protocol.  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.          APPENDIX B Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 1 of 3 CHRONOLOGICAL SITE HISTORY Perth Mini Mart 818 Perth Road, Troutman, NC Facility ID#: 00-0-0000024524 NCDWM UST Incident No.: 40784 Terraquest Project No.: 08217 March 4, 1980 According to the North Carolina UST Database Records, two 6,000- gallon gasoline, one 4,000-gallon gasoline, and one 2,000-gallon diesel USTs were installed at the site. November 16, 2017 Terraquest personnel mobilized to the Perth Mini Mart facility to conduct a limited scope site check. The UST owner had recently noted inventory record discrepancies based upon ATG reading for UST T3. To investigate these irregularities, the UST owner had a tank tightness test completed on this UST which resulted in failure. In response, the UST owner submitted an UST-17A UST Suspected Release 24-Hour Notice Form. A site check was then required to investigate a potential release of petroleum. Soil quality was assessed through the advancement of four soil borings (B1 – B4) around the suspect UST. Samples from the B1(18-20), B2(8- 10), B3(8-10), and B4(13-15) were submitted for laboratory analysis per EPA Method 8015 utilizing the 5030-extraction method for gasoline range organics (GRO). Analytical results of the collected soil samples revealed detectable concentrations of TPH GRO in each sample; however, only the B1(18-20) sample contained a TPH GRO concentration (497 ug/kg) above the 100 mg/kg action limit. December 8, 2017 Terraquest submitted a copy of the Site Check Report Letter and UST- 61 24 Hour Release Reporting Form were submitted to the NCDWM- UST. Three soil samples were collected from the MW1 soil boring at the 10-12 ft. BGL, 20-22 ft. BGL, and 30-32 ft. BGL intervals. December 19, 2017 The NCDWM-UST issued an NORR that confirmed receipt of the Site Check Report and requested the completion of an LSA. January 16, 2018 Terraquest personnel supervised the installation of one Type II groundwater monitoring well (MW1) as part of a Phase I LSA in the vicinity of the previous B1 soil boring. Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 2 of 3 January 22, 2018 Terraquest personnel collected a groundwater sample from monitoring well MW1 after gauging the well for free product using an oil/water interface probe that did not detect any measurable amount of free product. Prior to groundwater sample collection, Terraquest gauged 6.25 feet of free product in monitoring well MW2. No additional wells contained free product on this date. Groundwater samples were collected from monitoring wells MW3 and MW4. March 19, 2018 The NCDWM-UST LUST Trust Fund issued a correspondence regarding the Commercial State Trust Fund Eligibility Application. The release incident was found conditionally eligible following a $20,000 deductible that was noted as having been met. June 18-19, 2018 Terraquest personnel supervised the installation of three additional monitoring wells (MW2 – MW4) as part of the Phase II LSA. August 3, 2018 Terraquest submitted an LSA Report (Phase I & II) to the NCDWM-UST. August 6, 2018 Terraquest requested pre-approval of costs necessary to complete a CSA. September 6, 2018 Terraquest requested pre-approval of costs necessary to conduct free product recovery via MMPE. September 11, 2018 The NCDWM-UST grants pre-approval of costs for free product recovery via MMPE. October 3, 2018 The NCWM-UST grants pre-approval of costs for CSA activities. October 22-26, 2018 Terraquest supervised an MMPE event at the site. A total of 4, 041 gallons of a free product/contaminated groundwater mixture were recovered. November 26-28, 2018 Terraquest personnel supervised the installation of groundwater monitoring wells MW5-MW11. These wells were installed as part of the CSA. Monitoring wells MW5-MW10 are Type II wells installed for horizontal assessment while monitoring well MW11 is a Type III well installed for vertical delineation of contamination. Soil borings December 3, 2018 As part of the CSA, Terraquest personnel sampled monitoring wells MW1 – MW11 and surveyed the casing elevations of recently installed wells MW5-MW11. Slug tests were conducted on monitoring wells MW3, MW5, and MW7. Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 3 of 3 October 7-11, 2019 Terraquest supervised an MMPE event at the site. Free product was removed from monitoring well MW2. A total of 3,027 gallons of contaminated groundwater was removed. Emissions stack calculations indicate the exhaust of 20.57 gallons of petroleum. June 1, 2, and 3, 2020 Terraquest supervised a high-resolution study conducted by Dakota Technologies Company, LLC. The study was requested by the NCDWM- UST to identify the location of free product and involved the advancement of ten borings that were analyzed using an Ultra-Violet Optical Screening Tool (UVOST). September 22-23, 2020 Terraquest supervised the installation of three free product monitoring wells, MW15, MW16, and MW17. A free product evaluation was performed on monitoring well MW2. Groundwater monitoring wells without free product were sampled and sent off for VOC analysis. While there were no indications of a release from the diesel AST, STF demanded that 625 analysis be performed on all wells at the site at a cost exceeding $3,000 to rule out a release. March 22-26, 2021 Terraquest supervised an MMPE event at the site. Free product was removed from monitoring wells MW2, MW16, and MW17. A total of 4,679 gallons of contaminated groundwater was removed. Emissions stack calculations indicate the exhaust of 20.72 gallons of petroleum. April 21, 2021 Terraquest personnel gauged monitoring wells and found free product in MW16 (1.49’) and MW17 (0.05’). November 16-17, 2021 Terraquest supervised the installation of pilot test wells SVE1, SVE2, SVE3, and AS1. November 22-23, 2021 Terraquest conducted SVE and air sparge pilot tests.

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 November 22-23, 2021, Terraquest performed SVE testing using SVE pilot test wells SVE1, SVE2, SVE3, and monitoring wells MW1, MW2, and MW16. SVE1 and SVE3 were used as the extraction wells and the other wells were monitored for influence. Terraquest personnel supervised the construction of SVE wells SVE1, SVE2, and SVE3 on November 16, 2021. The wells were installed in preparation for the pilot test. Monitoring wells MW1, MW2, and MW16 were installed as part of previous assessment activities. Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 2 The new wells were installed by an NC-licensed driller operating a Geoprobe model 7822 drilling unit that turned solid-stem augers. Wells SVE1, SVE2, and SVE3 were constructed of twenty feet of 2”-diameter PVC casing attached to fifteen feet of 2”-diameter screen with a 0.010” slot size for a total well depth of thirty-five feet. A sand gravel pack was placed around the screened section of each point. This section was isolated from the surface by bentonite and grout seals. Well construction records are attached. Site Hydrogeology The site is located in the Piedmont Physiographic Region of North Carolina. According to the Geologic Map of North Carolina (Brown, et al, 1985), the site is located in the Charlotte Belt and is underlain by mafic metavolcanic bedrock lithologies. On a regional scale, the Piedmont is characterized by land with moderate relief and some areas of low relief hills and valleys. Groundwater in the region is part of the Catawba River Basin. Regionally, groundwater flows to the southwest and feeds into Big Branch Creek and ultimately Lake Norman. Big Branch Creek is listed as a Water Supply IV surface water body at https://deq.nc.gov/about/divisions/water- resources/planning/classification-standards/classifications#DWRPrimaryClassification which classifies surface water bodies with a WSIV classification as “sources of water supply for drinking, culinary, or food processing.” Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 3 The following lithologies were encountered at the site during the installation of soil borings and the monitoring well network: 0 – 63’ BGL SILT (CL) Mostly soft to medium-stiff (generally increasing consolidation with depth), micaceous, red to brown to tan silt with trace clay and characteristics of saprolite in areas. 63-70’ BGL SAPROLITE Mostly tan/brown heavily-weathered rock.

Test Date: 11/22-23-21 Report Prepared: 12/23/21 6 The phreatic aquifer at the site ranges from 21 to 40 feet BGL with an average depth to water in the Type II wells since 2018 of 32 feet BGL. (Notably, free-phase product is present in multiple wells with historical thicknesses as great as 7 feet.) As part of the CSA, the groundwater elevation measurements reveal that the hydraulic head within the shallow phreatic aquifer ranged from a relative value of approximately 66.61 at monitoring well MW5 to 67.91 at MW4 as measured on April 30, 2019. In conjunction with other site measurements, the results indicate flow in the phreatic aquifer in a south/southwest direction under an average hydraulic gradient of approximately 0.02. Groundwater elevation data collected on November 23, 2021 prior to testing is listed in Table 1 along with well construction information. The potentiometric surface on that date is displayed below and indicates a west/southwest groundwater flow direction.

Test Date: 11/22-23-21 Report Prepared: 12/23/21 7 General applicability based on soil type and contamination (gasoline at this release incident): 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: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 8 Subject Soil Contamination Through the 2017 Site Check, 2018 LSA, the 2019 UST closure, the 2019 over-excavation, and the CSA, a total of fifty-seven samples were collected to delineate the extent of soil contamination. The area of STG MSCC violation is generally centered on the UST basin with a smaller area around the northern dispenser island. The volume of contamination is a sum of these two areas. With an average depth to water of 31 feet in monitoring wells near the UST basin in April 2019, the calculated tonnage at the site includes 1,220 tons near the basin and 15 tons at the northern dispenser area. This volume accounts for the previously excavated area. The area is shown here: Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 9 Soil Mass Calculations: Knowing the contaminant mass allows an understanding of remediation progress based on removal rates. The mass is calculated here. Based on a known mass of contaminated soil and known mass of smear zone, a mass of contaminant can be estimated using the known contaminant/mass values from laboratory results. Using an average contamination value of 2,325 mg/kg from assessment results and the previously stated 1,220 tons + 15 tons = 1,270 tons of contaminated soil/smear zone, the following calculations yield a soil contamination mass of 5,893 pounds. 2,325 mg/kg x (1,270 tons x (907.185 kg / 1 US ton)) = 2,325 mg/kg x (1,152,125 kg) = 2,678,690,625 mg of contamination 2,678,690,625 mg / 1,000,000 mg/kg = 2,679 kg 2,679 kg x 2.2 pounds/kg = 5,893 pounds GENERAL PROCEDURES Terraquest performed one true SVE test within the vadose zone near the former UST basin where the largest contaminated soil mass exists (SVE1) and a second test above the free product area during the air sparge test (SVE3). The tests were conducted on November 22 and 23, 2021, respectively. Testing at SVE1 was the chief set of tests with SVE3 conducted to verify those results, i.e. radius of influence about the same, and to collect information for the sparge test that was conducted at the same time. 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. Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 10 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. Two types of SVE tests were conducted at SVE1. The first type of test conducted was an air permeability test that typically lasts for approximately 10 minutes. Vacuum was applied to the extraction well and the pressure responses in various observation points were recorded with time. The data is used to calculate the vadose zone permeability to air flow (intrinsic permeability). The second type of test performed was a steady state test. These 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. 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.

Test Date: 11/22-23-21 Report Prepared: 12/23/21 11 SPECIFIC PROCEDURES AND RESULTS Terraquest personnel conducted three air permeability tests on November 22, 2021. Tests were conducted using SVE1 as the extraction well, while SVE2, SVE3, and MW1 were observed in each of the respective tests. Information regarding the wells is as follows: Well identification Radial distance (feet) from extract point Screened interval (feet) Total depth (feet) Well diameter (inches) SVE1 0: extraction here 20-35 35 2 MW1 11 30-50 50 2 SVE2 7 20-35 35 2 SVE3 21 20-35 35 2 The air permeability tests were conducted for fifteen minutes each. During the tests, magnehelic gauges were used to measure the vacuum influence at the observation well. The field results for these tests are included in SVE-Table 1. As shown on that table, influence was seen at all observation points. After the air permeability data was collected, the system was turned off and allowed to equilibrate prior to conducting the steady state test. The steady state test consisted of four short- term (30 minutes) tests that were conducted one after another using various extraction well vacuum pressures to assess the vadose zone response. The primary objective of these tests was to establish a relationship between vapor flow and applied vacuum. SVE1 was used as the extraction point for the November 22 test and SVE3 was the extraction point for the November 23, 2021 test. The monitoring results are attached as SVE-Table 2. Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 12 For the steady state test on SVE1, Terraquest applied a vacuum of -22 inches of water for a half- hour, -40 inches of water for a half-hour, -60 inches of water for a half-hour, and -70 inches of water for the last half-hour. Vacuum was controlled via a dilution valve. Similarly, the steady state test using SVE3 as the extraction point while monitoring wells MW1, MW2, MW16, and MW17 was run at progressive dilutions of -22 inches of water for a half-hour, -40 inches of water for a half-hour, and -80 inches of water for a half-hour. The results are shown in SVE-Table 2. Pore volume: From Equation (18) in Johnson et al (1990b), the estimated time to remove one pore volume (Tp) is estimated by: Where: EA = air filled void fraction of soil matrix R = radius of zone of contamination (feet) H = thickness of zone of venting (feet) Q = air flow rate (cubic feet per minute) Data from the SVE1 steady state test was used to estimate Tp. With the variables assigned as follows: EA = 0.15 (based on an average effective porosity published by Sanders, 1998) R = 44 feet H = 11.7 feet (SVE1 dtw on 11/22 31.7 feet. screen 20-31.7 = 11.7 feet) Q = 8 cubic feet per minute (average) Q HRE=T Ap 2π Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 13 An estimated time to remove one pore volume of contamination is calculated to be: (0.15 x 3.14 x 44^2 x 11.7) / 8 = 1,334 minutes (~22 hours) Since the SVE steady state test did not run for that long, it is unlikely that a full pore volume was removed. As shown on SVE-Table 2, VOC concentrations were noted throughout the entire test. DATA ANALYSIS Air Permeability: Terraquest used US EPA’s (1993) Hyperventilate program to evaluate the air permeability test data. Hyperventilate uses the transient pressure response in the observation point to calculate an air permeability value using a theoretical relationship developed by Johnson, et al (1990a). Hyperventilate results are attached at the end of this appendix report. The estimated value of intrinsic permeability (k) for varying soil lithologies ranges from 10-1 (clayey silts) to 105 darcy (gravel) as shown on Help-page 13 that supports page 8 of the attached Hyperventilate analysis. Terraquest chose to enter a darcy value range from 0.25 to 1 as it most accurately represented the flow ranges that were observed during the pilot tests. Radius of Extraction Well Influence: The ROI was determined based upon data from the steady state test. A rule-of-thumb recommended by U.S. EPA (1995) is that the ROI will be the distance at which a vacuum of 0.1 inches of water is yielded. To determine this distance, Terraquest plotted vacuum pressure versus distance. This graph has been included. When determining the point at which 0.1 inches of water is yielded, a straight-line relationship was drawn from the extraction point through the observation points in a best-fit manner. The graph shows a corresponding x-axis crossing of 23.5 Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 14 feet. A 20 foot radius is chosen as a conservative estimate of influence that allows for some site heterogeneities. Number of Extraction Wells: Hyperventilate was used to calculate the number of extraction wells by examining the site’s permeability, critical volume of air, extraction well efficiency, contaminant radius from extraction well, contaminant concentration, radius of influence, and required cleanup time. The following values were constant throughout the calculations: (see card SD2 and 3) • permeability (k) of 0.25 to 1 darcy (previously discussed), • critical volume of air of 146.71 L/g (see card SD7), • extraction well efficiency of 30 percent (see card H29) • Average contamination concentration across subject area of 2,325 mg/kg (previously discussed), • Radius of test influence of 20 feet, • Cleanup time of three years. The required number of wells calculated by Hyperventilate ranged from 1 to 11 based on area and critical volume calculations. The data does not consider site heterogeneities, the requirement of the SVE system to recover free-phase product and sparge vapors and is a rather large range. Site structures and installation feasibility must also be accounted for. In consideration of the aforementioned items, Terraquest recommends the installation of ten SVE wells at the locations shown on the next page and on Figure 4.

Test Date: 11/22-23-21 Report Prepared: 12/23/21 16 CONTAMINANT MASS REMOVAL In addition to the mass removal estimates provided in the Hyperventilate analysis, Terraquest also collected an air sample from the SVE pilot test exhaust stream that also requires consideration toward mass removal. During the SVE pilot test, Terraquest personnel filled a 1L Tedlar bag with a representative air sample from the exhaust stack. As shown in the attached analytical report, the results of lab analysis listed a TPH concentration of 5,070,000 parts per billion by volume (ppbv). Operational SVE system generally have exhaust readings in the 10,000-100.000 ppbv, so >5,000,000 is significant. Using published blower performance curves and the time of operation, the following 22.56 pounds / 3 hours removal rate is calculated: minutes bump test 15 air permeability test 1 15 air permeability test 1 15 air permeability test 1 15 steady state test 120 180 SVE: this model produces (scfm flow rate):100 scfm TPH concentration of vapors at stack:5,070,000 ppbv Volume of air removed is (flow in cubic feet per minute) x length of testing (in minutes)18,000 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 (ft 3 gasoline vapor/1E+09 ft 3 air)]91 ft3 gasoline vapor Conversions:1 ft3 vapor equals 7.48 gal. 1 gal. equal 3.78 liters ft 3 gasoline vapor x 7.48 gal./ft 3 x 3.78 liters/gal. equals liters gasoline vapors.2,580 liters gasoline vapor Conversions: Therefore: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 lb/454 g) equals lbs. vapor 22.56 lb of gasoline At standard temperature and pressure, there are 22.4 liters of gasoline vapor per mole of gasoline. The molecular weight of carbon in gasoline is 89 g/mole. Soil Vapor Extraction Pilot Test Report For: Perth Mini Mart, 818 Perth Road, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Date: 11/22-23-21 Report Prepared: 12/23/21 17 Disregarding all other factors, mathematically, the removal rate of the pilot test would indicate that at 22.56 pounds / 3 hours, the 5,893 pounds of soil contamination would be gone after 784 hours of SVE system operation. That is, after 33 days. This value isn’t close to 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. A more likely time frame is 2-3 years. These calculations rely solely on true soil contamination. The larger driving force at the Perth Mini Mart will be free product and GCL violations. CONCLUSIONS Based on the pilot test conducted by Terraquest personnel, the site is acceptable for SVE as a remedial method. SVE is recommended to remediate soil, and remove free product and sparge exhaust vapors. Ten dedicated SVE wells are recommended.

The site’s location, vicinity, and layout are depicted on Figures 1, 2, and 3. Air sparging is an in-situ method of groundwater remediation, in which compressed air is injected into the aquifer via wells screened in the saturated zone. The compressed air is entrained as small air bubbles and air streams which rise through the pore network in the soil structure and fractures of saprolite. Volatile organic compounds dissolved in the water column or adsorbed to soil particles will, depending on subsurface conditions and properties of the target compounds, volatilize in the air stream. The entrained air eventually emerges to the vadose zone, where the load of organic gases is released to the soil vapor domain. In aquifers with concentrations of dissolved oxygen that have been lowered through natural aerobic degradation of the Air Sparge Pilot Test Report Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 2 hydrocarbon contaminants, the injection of air can replenish the dissolved oxygen and accelerate the rate of biodegradation. As part of the remedial action toward closure for this site, Terraquest identified air sparging as a potentially viable groundwater remediation method. This test was conducted within the area of free product as requested by the NCDWM-UST. The purpose of the pilot tests was to confirm the subsurface would be agreeable to the method, to provide information for well spacing requirements, and provide system performance requirements for an onsite system. Contaminant recovery rates for early operation of a sparge system can also be understood via pilot testing. The tests revealed how the subsurface responds to injection of air bubbles within the aquifer. Data was collected for air injection pressure, air injection flow, and changes in free product/groundwater levels. Site Hydrogeology The site is located in the Piedmont Physiographic Region of North Carolina. According to the Geologic Map of North Carolina (Brown, et al, 1985), the site is located in the Charlotte Belt and is underlain by mafic metavolcanic bedrock lithologies. On a regional scale, the Piedmont is characterized by land with moderate relief and some areas of low relief hills and valleys. Groundwater in the region is part of the Catawba River Basin. Regionally, groundwater flows to the southwest and feeds into Big Branch Creek and ultimately Lake Norman. Big Branch Creek is listed as a Water Supply IV surface water body at https://deq.nc.gov/about/divisions/water- resources/planning/classification-standards/classifications#DWRPrimaryClassification which Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 3 classifies surface water bodies with a WSIV classification as “sources of water supply for drinking, culinary, or food processing.” The following lithologies were encountered at the site during the installation of soil borings and the monitoring well network: 0 – 63’ BGL SILT (CL) Mostly soft to medium-stiff (generally increasing consolidation with depth), micaceous, red to brown to tan, with trace clay and characteristics of saprolite in areas. 63-70’ BGL SAPROLITE Mostly tan/brown heavily-weathered rock.

Test Dates: 11/23/21 Report Prepared: 12/20/21 6 The phreatic aquifer at the site ranges from 21 to 40 feet BGL with an average depth to water in the Type II wells since 2018 of 32 feet BGL. (Notably, free-phase product is present in multiple wells with historical thicknesses as great as 7 feet.) As part of the CSA, the groundwater elevation measurements reveal that the hydraulic head within the shallow phreatic aquifer ranged from a relative value of approximately 66.61 at monitoring well MW5 to 67.91 at MW4 as measured on April 30, 2019. In conjunction with other site measurements, the results indicate flow in the phreatic aquifer in a south/southwest direction under an average hydraulic gradient of approximately 0.02. Groundwater elevation data collected on November 23, 2021 prior to testing is listed in Table 1 along with well construction information. The potentiometric surface on that date is displayed below and indicates a west/southwest groundwater flow direction.

Test Dates: 11/23/21 Report Prepared: 12/20/21 8 Based on the previous hydrogeologic descriptions alone, the phreatic aquifer at the site is a reasonable candidate for air sparging. The amount of clay and consolidation will play a large role in the effectiveness of sparging. Well Installation and Layout In addition to the existing monitoring well network, an air sparge well was installed in anticipation of the subject air sparge test. Terraquest personnel supervised the installation of air sparge well AS1 on November 16, 2021. Well AS1 was installed using a Geoprobe Model 7728DT drilling rig operated by an NC-Licensed driller. The well was constructed of 55 feet of 1”-diameter PVC casing attached to 5 feet of 1”- diamter PVC screen for a total well depth of 60 feet. Table 1 and the attached well record provide further details. The well was placed within the free product plume at the direction of the NCDWM-UST. Monitoring wells MW1, MW2, MW15, MW16, and MW17 were installed as part of previous assessment efforts and were used as observation points for this ai sparge test. Additional summary of the wells as it relates to testing follows: Well identification Radial distance (feet) from injection point Screened interval (feet) Total depth (feet) Well diameter (inches) AS1 0: injection here 55-60 60 1 MW2 5 30-50 50 2 MW17 5 20-45 45 2 MW15 15 25-45 45 2 MW16 16 25-45 45 2 MW1 22 30-50 50 2 Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 9 Equipment and Connections Air was supplied to the injection point from a portable, electric, oil-less air compressor powered by a portable electrical generator brought onsite for the test. The compressor output was connected to the injection point through a series of hoses, pipes, and fittings. Air flow into the injection point was measured with an adjustable flow meter. A static pressure gauge was installed downstream of the flow control valve. The change in depth to product and water in the observation points was measured using a Solinst Model 122 Interface Meter. GENERAL PROCEDURES The test procedure consists of applying air pressure to the sparging well while monitoring air flow at this point and changes in product/groundwater levels in nearby wells. During the air sparge test conducted on November 23, 2021, air was introduced into AS1 while measurements were collected from observation points MW1, MW2, MW15, MW16, and MW17. The test consists of several stages in which a constant flow is applied, while the air pressure and water levels are measured. After groundwater mounding stabilizes, the flow is stepped up and held constant for another stage. The number of stages depends on the rate at which responses occur. During the November 23, 2021 test, a total of three different flow rates were applied to the air sparge well. Flows of 1.0, 1.5, and 2.0 standard cubic feet per minute were all applied. Those flow intervals were provided for 1 hour, 1.5 hours, and 1.5 hours, respectively. That is, 1.0 scfm was applied for the first 60 minutes, 1.5 scfm was applied from 60 to 180 minutes, and 2.0 scfm was applied from 180 minutes until test conclusion at 270 minutes. Measurements recorded during these stages are presented on Table 2.

Test Dates: 11/23/21 Report Prepared: 12/20/21 10 MEASUREMENTS AND RESULTS The three main objectives of data analysis are to determine whether air sparging is suitable for the site, determine a reasonable radius of influence for an air sparge well, and establish data for equipment selection in the design of a full-scale system. Suitability The responses observed during the test indicate air sparging would be suitable for the site. Air was injected into the subsurface and flow was maintained. Some sites have had poorly installed air sparge wells where the screens are cemented or the lithology is too tight and air will not enter the saturated zone at all. This was not the case at the subject facility. The injection was made with a standard electrical air compressor suitable for short-term testing and flowable air was maintained without a large amount of pressure. Flowable pressure for the test was less than 20 psi and a larger spike for breakthrough pressure was not observed. While some breakthrough pressure exists, it was obviously within the limits of the operating equipment and was short-lived enough that field personnel did not see it. There are other general conditions that contribute to AS effectiveness. These are discussed in US EPA (1995), and some are listed and addressed below. • Basements, subsurface utilities, etc. - Air sparging has the potential to exhaust elevated concentrations of VOCs to the vadose zone, where they could accumulate in basements, sewers, crawl spaces, etc. Implementation of AS should consider this possibility. At this site, no basements are known to exist nor are there any building crawl spaces as structures appear of slab construction. As the majority of the subject area is covered in asphalt or concrete, air sparge off-gassing could migrate along utility pathways if not collected by a vacuum recovery system. Regulation of the sparge rate and placement of the injection points are additional controls.

Test Dates: 11/23/21 Report Prepared: 12/20/21 11 • Unconfined or Confined Aquifer - Air sparging is generally not recommended for confined aquifers. The target zone at this site would be in the unconfined aquifer, so this factor should not be prohibitive. • Type of Contamination - Gasoline is the contaminant at this site. Of the common petroleum fuels, gasoline is the most amenable to remediation by sparging. That is shown on the following exhibit from the EPA’s 1995 guidance document (US EPA 1995): • Soil Type - If the stratigraphy is comprised of tight soils or large amounts of clay, then sparging is not likely to be effective. However, while some clay was logged at this site, the US EPA. 1995. How to evaluate alternative cleanup technologies for underground storage tank sites. Solid Waste and Emergency Response 5403W.

Test Dates: 11/23/21 Report Prepared: 12/20/21 12 predominant soil matrix within the saturated zone is silt. This was confirmed by the low pressure needed to maintain injection flow and by the response at surrounding wells. Radius of Influence Determining the radius of influence involves a study of the influence observed in the wells monitored during the pilot test. As the remedial method of air sparging is the mechanical stripping of contaminants from the dissolved phase into a liberated waste air stream, the extent of that effect is what is searched for. Air sparging also acts as a remedial method by increased the amount of oxygen dissolved in the surrounding aquifer and that should be analyzed too. However, the presence of free product prevented field measurement of DO with routine equipment and this data was not obtained. Prior to and throughout the test, the depth to water was measured in surrounding wells. As the test progressed, the water table was mounded by the applied air as seen at observations wells by a rise in the water table. In a fully evolved test with a sufficiently low air flow, the water levels will subside to near static levels after some period of time as the mounding is spread across the aquifer. When this drop occurs, the air flow rate is typically increased to the next step. The measured data is summarized on the attached Table 2 and a graph of the depth to water versus time for each of the wells monitored is also provided at the end of this sparge report. These graphs show the mounding and subsequent stabilization of groundwater during each flow increase. The stabilization is slight and is realized by a tapering of water mounding in some cases. The evidence of these water level stabilizations is an important result, since it indicates that low flow sparging can be performed without causing sustained high water levels. These measurements also are indicative of the radius of influence of the air sparge well. The following results were observed: Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C.

Test Dates: 11/23/21 Report Prepared: 12/20/21 14 Calculating the radius of influence should take into account multiple factors to provide a scientifically-reasonable value with some conservative allotment. The radius is subject to hydrogeology and isn’t as simple as a straight-line graph. The data indicates mounding as far away as 34 feet. The goal is to calculate a ROI that provides air sparging to all areas without creating service gaps. The size, shape, and placement of the free product and dissolved-phase plume onsite where the sparging would occur also needs consideration. In consideration of all these factors, 20 feet is recommended as a working radius of influence and the following well placement is proposed that considers site layout, remedial goals, free product, GCLs, and radius of influence: (see attached Figure 4 also) Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 15 Design data The air sparge test achieved sustained flow up to 2 scfm at a pressure between 12 and 17 psi. Equipment should be sized for a flow demand of 7 wells at a flow rate up to 4 scfm each for a total of 28 scfm with some extra to allow for an increase in sparging as needed. Pressure over 17 psi was not observed but could have happened briefly as breakthrough was occurring. Air sparge breakthrough is typically 1 psi for every 2.3 feet of head (US EPA 1995). With a head of 55 – 32.13 = 22.87 feet, the entry pressure required is estimated at 9.94 psi. The lithology accounts for some of the additional pressure required. Overall, the flow and pressure is within the range of typical air sparge systems. Contaminant Mass 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 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. With that in mind, the following is presented: Free-phase product mass: 325 ft2 x 2.5 foot average product thickness = 812.5 ft3 x 7.48 gal/ft3 x 6.25 lbs/gal = 37,984 pounds Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 16 Dissolved-phase contaminant mass (GCL violation): 3,300 ft2 x (10 feet beyond bottom of 50 foot wells – DTW 32’ = 60-32=28) = 92,400 ft3 x 28.3 L/ft3 = 2,616,476.6 L of GCL water. Average GCL violation wells on 9/2020 = 72,730 ug/L. 2,616,476.6 L of GCL water x 72,730 ug/L x 2.20462e-9 ug/lbs = 419.5 pounds. Initial removal rate: A Soil Vapor Extraction (SVE) unit was operated during part of the air sparge test to retrieve a representative sample of the air sparge exhaust. As shown in the attached analytical report, that sample had a reported concentration of 10,100,000 parts per billion by volume of Total Petroleum Hydrocarbons as Gasoline Range Organics. Using the following calculations, the removal rate during the test was: 67.42 pounds/4.5 hours OPERATING PERIOD:START: 11/23/21 11:37 AM END:11/23/21 4:07 PM AIR SPARGE CALCULATIONS (via SVE sample recovery) SVE: this model produces (scfm flow rate):100 scfm TPH concentration of vapors at stack:10,100,000 ppbv Volume of air removed in ft3 equals (flow)(1,440 min/d)(time in period)27,000 ft3 Volume of gasoline vapor removed is equal to air volume removed muliplied by the TPH concentration.

The molecular weight of carbon in gasoline is 89 g/mole. Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 17 Expanding the initial removal rate against the mass of contaminant calculates as follows: 37,984 pounds + 419.5 pounds = 38,403.5 pounds / (67.42 pounds/4.5 hours) = 2,563 hours / 24 hours/day = 107 days. So, if a treatment system were installed that had removal rates like those of the pilot test, the contaminant mass would be removed in 107 days. However, this does not account for water table fluctuations, lithology heterogeneities, or compounds more recalcitrant to air stripping. It also ignores the readily available contamination that is liberated by a virgin pilot test. At some point, air sparge liberation at similar sites has shown a drastic reduction in contaminant recovery as the system run time increases. Having several feet of free product available for removal may allow the “early and productive” stages of the sparge 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 107 days. A 4-5 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. The longer portion of treatment may not be the product removal but the remediation of the dissolved-phase contamination. The recovery rate of the GCL violations was not investigated during the pilot test as the NCDWM-UST directed the placement of the air sparge well into the free product plume. Several years of treatment are anticipated to remove product and GCL violations. Further refinement of treatment time will be understood as the system is operated or by conducting a level of research and pilot testing of length that exceeds the scope of work for NCDWM-UST RRD pilot testing. Air Sparge Pilot Test Report Perth Mini Mart – Madhukunj, LLC, Troutman, Iredell County, NC Prepared by: Terraquest Environmental Consultants, P.C. Test Dates: 11/23/21 Report Prepared: 12/20/21 18 CONCLUSIONS AND RECOMMENDATIONS A November 23, 2021 air sparge pilot test conducted for the release incident at the Perth Mini Mart indicates favorable remedial response from the subsurface. Air sparging was conducted at flows and pressures of typical systems, influence was observed at surrounding wells, and recovery of the sparge exhaust had reported contamination therein. Overall, air sparging appears to be a viable option for treatment and is recommended. Note that the presence of free product and concentration noted in the exhaust stack indicates that stack treatment via thermal oxidation will be required to ensure emissions do not exceed permissible limits.
