For additional information please refer to subsequent sections of this report. • CES of NC, PLLC (CES) was retained by GPM Southeast, LLC (GPM) to complete additional monitoring at the site during the second half of 2022. The activities were in response to correspondence dated November 22, 2022, issued by the North Carolina Department of Environmental Quality (NCDEQ). The services were provided in general accordance with the NCDEQ UST Section “Assessment Guidelines” and “Corrective Action Guidelines”. • Multiple releases have been reported at the site from former underground storage tank (UST) systems between 1998 and 2002. Free product has historically been reported at the site and recovered via passive skimming, hand bailing, sorbent socks, and aggressive fluid vapor recovery (AFVR). The site monitoring wells are currently on a semi-annual sampling schedule. • CES personnel visited the site on August 9, 2022, for sock replacement, and then on October 19, 2022, for completion of semi-annual groundwater sampling events. Analytical results indicated exceedances to groundwater quality standards and an exceedance of the gross contaminant level (GCL) for tert-butyl alcohol (TBA). The extent of groundwater contamination appeared to be defined. • Free product was not encountered at the site in August or October of 2022. • Shallow groundwater flow direction is generally interpreted to toward the north and east towards a low in the general area of MW-11 and MW-21. • The current estimated mass of benzene, toluene, ethylbenzene, and xylenes (BTEX) in groundwater was calculated to be approximately 7.7 lbs. • In conclusion, the presence of free product and occasional exceedance of GCLs for groundwater contributes to the site’s risk ranking. The occurrence of free product appears to be related to periods of above average groundwater elevation, suggesting a secondary source in smear zone soil. • CES recommends continued semi-annual groundwater monitoring with supplemental free product recovery performed as needed. • Once measurable free product is no longer present and groundwater contamination has been demonstrated to have been remediated to below GCLs, the site risk ranking should be re-classified, and the incident considered for restrictive closure.

CES of NC, PLLC (CES) has prepared this report for GPM Southeast, LLC (GPM) and the North Carolina Department of Environmental Quality (NCDEQ) to document environmental monitoring activities performed at the subject facility during the second half of 2022 (monitoring period). In correspondence dated November 22, 2022, the NCDEQ generally agreed with recommendations for continued semi-annual groundwater monitoring and free product recovery, as needed, as presented in the April 2022 Groundwater Monitoring Report. GPM retained CES for environmental consulting services and the activities were provided in general accordance with the NCDEQ UST Section “Assessment Guidelines” and “Corrective Action Guidelines”. 2.0 SITE HISTORY AND CHARACTERIZATION The subject facility reportedly operated a UST system(s) from at least 1971 through 2002. Historical UST system information and owner/operator information are provided in Table 1 and Table 2, respectively. As required, the following provides information relevant to site history and characterization. 2.1 SITE LOCATION AND CURRENT FACILITY STATUS The GPM No. 3059 facility (Former Scotchman #59), herein referred to as the site, is located at 115 US Highway 117 South in Burgaw, Pender County, North Carolina. Figure 1 is a topographic vicinity map of the surrounding area and Figure 2 is a site map depicting pertinent structures. The property is owned by Coastal Carolina Carwash, LLC and is currently occupied by a commercial store and a self-service car wash. No UST systems are currently in use at the site. Twenty-five (25) active monitoring wells are currently associated with the site as listed in Table 3. 2.2 SITE HISTORY Historically, multiple release reports have been submitted to the NCDEQ. The first release was reported by in February of 1998 due to the presence of free product at the site. The second and third releases were reported during UST closure activities in May of 2001 and March of 2002, respectively. A summary of site history is provided below, detailed site history has reportedly been provided to the NCDEQ in previous submittals. Soil samples do not appear to have been collected at the site since Comprehensive Site Assessment (CSA) activities in 1999 (risk-based) and UST closure activities in 2001 and 2002 (total petroleum hydrocarbons) which were below industrial/commercial cleanup levels. Relevant historical documentation is included in Appendix A. A map depicting the extent of impacted soils above soil to water maximum soil contaminant concentrations (MSCCs) is included as Figure 3. On November 15, 1989, the North Carolina Department of Environment, Health, and Natural Resources (predecessor to the NCDEQ) issued a letter to Worsley Companies, Inc. (WCI), also formerly known as Worsley Operating Corporation, requesting actions to address free-floating petroleum product observed in a manhole between the site and adjacent gas station to the south of the site, noting that the source of the contamination had not yet been determined. On December 14, 1989, WCI submitted documentation to the NCDEQ including results of five (5) soil samples collected near the southern perimeter of the site indicating that only one (1) of the five (5) samples was above laboratory reporting limits (RLs) at a concentration of 18 parts per million (ppm) total petroleum hydrocarbons (TPH). WCI concluded that the contamination in the manhole did not migrate from the site, the detection in the soil sample was not significant based on the years of operation of the site as a gas station and suggested that the source of contamination was the adjacent gas station to the south. A release incident does not appear to have been generated from this assessment. WCI was notified by the NCDEQ of a suspected release resulting from failed UST tightness tests performed on November 25, 1996, and August 29, 1997. The validity of the failed tightness tests was refuted by WCI between December 19, 1997, and January 6, 1998, but ultimately the NCDEQ requested WCI to perform GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 2 activities to prevent any further releases and initiate environmental assessment activities. A Subsurface Petroleum Detection Summary Report was submitted by Clark Environmental Services, P.C. (Clark) in May of 1998, which documented installation of monitoring well MW-1, soil contamination, and the presence of free product in the subsurface and a storm water drainage ditch along the northern side of the property. A Limited Site Assessment Report (LSA) by Clark dated September 8, 1998, documented installation and sampling of monitoring wells MW-2 through MW-7 and T-1. Free product was detected in monitoring well MW-1 and groundwater quality standards were exceeded in all sampled monitoring wells. The report recommended application of aggressive fluid vapor recovery (AFVR). After multiple Notice of Violation (NOV) letters were issued to WCI by the NCDEQ, a CSA Report dated September 30, 1999 by Clark documented advancement of four (4) soil borings (SB-1 through SB-4), installation of monitoring wells MW-8 through MW-17 (although no construction records have been located for MW-16 and MW-17), and installation of ten (10) temporary monitoring wells (TW-1 through TW-9 and TW-7A) along the western perimeter of the site to assess impacts near a subsurface preferential pathway. Results of soil samples indicated a significant extent of soil contamination across the site. Free product was detected in five (5) monitoring wells and the groundwater contaminant plume encompassed most of the site property boundaries. Additionally, recovery of approximately 29-gallons of free product and 902-gallons of groundwater by AFVR was reported. Development of a Corrective Action Plan (CAP) and product recovery via AFVR and installation of an interceptor trench was recommended. The site was ranked “Intermediate” risk by the NCDEQ. As requested by the NCDEQ, a CSA Addendum and Free Product Recovery Report was submitted by Delta on May 31, 2000, which contained a professionally surveyed site map, current depth to water measurements, an updated receptor survey, and documentation of an AFVR performed on May 2, 2000, that recovered approximately 41 gallons of free product. The report recommended application of additional AFVR. Additional assessment activities were documented in a Free Product Recovery Report dated May 3, 2001, by Delta. The activities included advancement of ten (10) soil borings (SB-1 through SB-10), installation of four (4) recovery wells (RW-1 through RW-4), and four (4) additional AFVR events conducted on June 28, 2000, December 27, 2000, February 2, 2001, and March 30, 2001. The AFVRs reportedly recovered approximately 391-gallons of free product, but soils remained impacted above regulatory limits primarily around monitoring well MW-17. Five (5) USTs consisting of one (1) 4,000-gallon gasoline, two (2) 2,000-gallon gasoline, one (1) 2,000-gallon kerosene, and one (1) 550-gallon of unknown contents (ID Numbers 1, 4, 5, 7, and 10) were removed from the central portion of the site, north of the dispenser canopy, on May 10, 2001, as documented in the UST Closure Report dated August 29, 2001, by Delta. All of these USTs were reported to contain rusting, pitting, and small holes. Approximately 60 cubic yards of soil were excavated and transported off-site for disposal. The report concluded that although soil contamination was detected above regulatory limits, additional assessment did not appear warranted due to a completed CSA for the site and the status of corrective action. A Phase II LSA Report dated February 28, 2002, by Delta documented installation and sampling of monitoring well DW-1 to assess the vertical extent of groundwater contamination at the site and an updated receptor survey, which revealed the presence of one potable well located approximately 750-feet south of the site (subsequent reports do not substantiate this). The report also indicated that a product recovery trench had been installed at the site on February 20, 2002, but not utilized due to lack of product observed in the GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 3 trench. The report concluded that active remediation should continue pointing to the success of five (5) AFVRs performed to date. The vertical extent of groundwater contamination was considered to be defined and the site was re-ranked to “High” risk. Five (5) additional USTs consisting of one (1) 4,000-gallon gasoline, one (1) 3,000-gallon gasoline, one (1) 3,000-gallon of unknown contents, and two (2) 1,050-gallon of unknown contents (ID numbers 2, 3, 6, 8, and 9) were removed from the vicinity of the middle of the southern property line of the site, south of the dispenser canopy, between March 26 and 27, 2002 as documented in the UST Closure Report dated April 26, 2002 by Delta. The report indicated free product was encountered on excavation waters. During excavation activities, two (2) unknown USTs were inadvertently punctured and released additional product/water mixture into the excavation which was subsequently removed. Approximately 100 cubic yards of soil were excavated and transported off-site for disposal. The report concluded that soil contamination was also detected and recommended development of a CAP along with continued free product recovery efforts. A Corrective Action Plan was requested by the NCDEQ on June 20, 2002 and submitted by Delta on October 31, 2002. The CAP report documented installation of recovery wells RW-5, RW-6, and RW-7. The CAP recommended mitigation of free product via continued use of AFVR followed by soil vapor extraction and air sparging to remediate soil and groundwater at the site. Natural attenuation was recommended for clean-up of off-site impacted groundwater. At this time a car wash and convenience store (no petroleum retail) were active on the site. Monitoring wells MW-1, MW-2, MW-5, MW-6, MW-14, MW-15, RW-1, RW-2, RW-4, and RW-5 were destroyed during various phases of work at the site. Monitoring wells MW-2R, MW-5R, MW-6R, MW-14R, and MW-18 were installed by Delta on October 9, 2003, and a groundwater monitoring event was performed on October 15, 2003, as documented in the Monitoring Report dated November 26, 2003. An additional groundwater monitoring event was performed by Delta in March of 2004 as documented in a Second Pre-Corrective Action Plan Monitoring Report dated May 25, 2004. Environmental Services & Solutions, PLLC (ESS) was retained by WCI to perform free product recovery efforts from September 2005 to April 2013 as documented in the Site Status Update Letter Report dated March 12, 2013, by ESS. A comprehensive groundwater monitoring event and updated receptor survey was performed by ESS on November 22, 2013, as provided in a Groundwater Monitoring Report dated January 2, 2014, by ESS. Results of product recovery efforts from 2014 through 2015 were provided in a Free Product Recovery Report dated June 29, 2015, by Antea USA of North Carolina, Inc. (Antea). Additionally, nine (9) temporary monitoring wells (T-1 through T-9) were installed at the site in December 2014 to assist with placement of three (3) permanent monitoring wells (MW-19, MW-20 and MW-21) designed to intercept free product. The report indicated 0.61-gallons of free product had been recovered during the reporting period and recommended evaluation of passive skimmers to recover free product. At the request of the NCDEQ, a comprehensive groundwater monitoring event was performed by Antea USA of North Carolina, Inc. (Antea) in April of 2016 as documented in a Groundwater Monitoring Report dated September 19, 2016, by Antea which reported groundwater samples collected from monitoring wells MW-2R, MW-3, MW-5R, MW-6R, MW-11, MW-12, MW-16 through MW-21, RW-6, and RW-7 were above the groundwater quality standards. The report also indicated that manual free product recovery via hand bailing and sorbents was ongoing, and that approximately 1.27-gallons of free product had been recovered since December 19, 2014, although free product was not encountered during the sampling event. GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 4 The report recommended completion of site assessment by additional delineation via installation of off-site monitoring wells and product recovery via passive skimmers. As documented in the Groundwater Monitoring Report dated November 26, 2018, by CES, monitoring well gauging was performed in June, July, and August of 2018 and a groundwater monitoring event was performed on August 7, 2018. Free product was detected during the reporting period ranging from 0.02-feet to 0.03-feet thickness in monitoring wells MW-17 and MW-5R. Although free product was detected, gross contamination levels (GCLs) were not exceeded in groundwater samples. The report recommended annual groundwater monitoring and continued free product recovery and indicated that efforts to obtain off-site access to date had not been successful. CES performed monitoring well gauging in January, May, and July of 2019 with semi-annual groundwater monitoring in July and November of 2019 as documented in Groundwater Monitoring Reports dated September 17, 2019, and February 10, 2020. Monitoring wells MW-8 and MW-9 appeared to have sustained damage to the well casing sometime between May and July of 2019 and were inaccessible for sampling. Free product was only detected in October 2019 in monitoring wells MW-5R, MW-16, and MW-17 ranging in thickness from 0.01-feet to 0.03-feet. Concentrations exceeded the GCL in only monitoring well MW-17 for tert-butyl alcohol. Continued quarterly free product monitoring and semi-annual sampling was requested in addition to off-site assessment. A Groundwater Monitoring Report dated July 31, 2020, by CES documented off-site monitoring well installation, quarterly gauging and free product recovery via AFVR, and the results of a semi-annual groundwater monitoring event performed in June of 2020. The report concluded that monitoring wells MW-22 and MW-23 installed on June 14, 2020, had delineated the extent of groundwater contamination, two AFVR events performed in March and May of 2020 appeared to be effective at recovering residual free product at the site, and that groundwater contaminant concentrations remained above regulatory standards. Continued free product recovery and groundwater monitoring was recommended. Per the January 28, 2021, Groundwater Monitoring Report, additional AFVR events were conducted in September and November of 2020 followed by a groundwater monitoring event in December 2020, which indicated that groundwater contamination remained above regulatory standards. The report concluded that the occurrence of free product generally appeared to be related to periods of above-average groundwater elevation. Surfactant-enhanced product recovery was recommended. A Groundwater Monitoring Report dated July 19, 2022, by CES indicated that groundwater contamination remained above regulatory standards and TBA exceeded the GCL in recovery well RW-3. 2.3 OFF-SITE INCIDENT 3447 South of the site across East Fremont Street is an active gas station (facility 00-0-0000026037) named Brown’s Minute Mart. A release affiliated with that site’s USTs was reported in 1987. The site was closed with a Notice of Residual Petroleum for groundwater on July 1, 2008. Groundwater at Brown’s Minute Mart was last sampled on June 28, 2007 and at that time the previous well (RKA-MW-2) which is closest GPM’s Site 3059 MW-20 contained 3,390 microgram per liter (µg/L) of benzene. 3.0 POTENTIAL RECEPTOR INFORMATION Receptor surveys have been performed at the site by various consultants since 1998. Most recently, receptor information was updated by ESS on December 12, 2013. The receptor survey update included a physical survey of all properties within 1,500-feet of the source areas, completion of water supply well information GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 5 questionnaires, and review of publicly available information. As required, CES personnel have performed windshield surveys during subsequent site visits to search for any changes to receptors near the site. 3.1 WATER SUPPLY WELLS Although one (1) water supply well was historically reported to be present on parcel #J072-081-002 approximately 750-feet south of the site in 2002, the most recent receptor survey update did not reveal the presence of any water supply wells within 1,500 feet of the source areas. 3.2 PUBLIC WATER SUPPLIES Municipal water is provided by the Town of Burgaw Public Works Department to all developed properties within a 1,500 radius of the site. The source of water for the permitted supply system, PWS ID# 04-71-010, is groundwater from four (4) production wells ranging in depth from 310 to 458-feet below ground surface. The production wells appear to be set in the Peedee and Black Creek aquifers and are all located greater than 1,500 feet from the source areas. 3.3 SURFACE WATER As shown on Figure 1, the closest surface water body to the site is an intermittent drainage ditch/creek located approximately 100-feet northeast of the site, which drains eastward and discharges to Little Burgaw Creek located approximately 1,600-feet east of the site and ultimately feeds into Burgaw Creek, a Class C;Sw surface water body. The storm water system proximal to the site typically consists of drainage ditches along nearby roadways. Although surface water impacts were historically reported in a ditch traversing the northern side of the site, the ditch was replaced with a concrete pipe drainage system at some unknown time and no further impacts have been reported. 3.4 WELLHEAD PROTECTION AREA According to information provided by the NCDEQ, the site is not located within a Wellhead Protection Area, as defined in 42 USC 300h 7(e). However, the Town of Burgaw maintains Wellhead Protection Plan #9 associated with PWS ID# 04-71-010. A Well Protection Area is located approximately 1,200 feet west of the site. 3.5 SURROUNDING LAND USE The site is located within the Town of Burgaw limits. Land use in proximity to the US Highway 117 corridor is zoned Highway Business District (B-2). Properties to the west of the US Highway 117 corridor are generally zoned Residential District (R-12). Planning zones to the east of the US Highway 117 corridor consist of Residential District (R-20), Planned Unit Development District PUD-1 and Office and Institutional (O&I). Adjacent properties consist of commercial use. 3.6 SUBSURFACE STRUCTURES Subsurface structures include underground utilities in the rights-of-way of US Highway 117 and Freemont Street. These utilities include sanitary sewer, municipal water, communication, and poly vinyl chloride (PVC) drainage pipes. No basements or other habitable subsurface structures have been identified. 3.7 DEEP AQUIFERS AND REGIONAL GEOLOGY/HYDROLOGY The subject facility is located within the Atlantic Coastal Plain province. Overall, the Atlantic Coastal Plain slopes eastward at an average rate of less than three feet per mile. The coastal plain is basically flat in interstream areas but is broken by low escarpments adjacent to stream valleys. The topographic elevation of the site is approximately 44 feet above sea level. As part of the Atlantic Coastal Plain province, Pender County has three predominant potable water producing aquifer systems in the vicinity of the site. In descending order these include: GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 6 • Surficial aquifer comprised of Pleistocene and Pliocene age sediments, • Peedee confining unit and aquifer of Late Cretaceous age sediments, and, • Black Creek confining unit and aquifer of Late Cretaceous age sediments. Based on historical analytical results from deep wells installed on-site, only the uppermost portion of the surficial aquifer appears to be impacted. According to the NCDEQ Division of Water Resources Hydrogeologic Framework, the surficial aquifer is approximately 66-feet thick in the vicinity of the site. The Peedee confining unit lies beneath the surficial aquifer and is approximately 69-feet thick composed mostly of clay, silty clay, and sandy clay with less than 15 percent permeable material. The underlying Peedee aquifer is approximately 200-feet thick in the vicinity of the site and is composed of fine to medium grained sand interbedded with gray to black marine clay and silt. The sand beds are commonly gray or greenish gray and contain varying amounts of glauconite. Thin beds of consolidated calcareous sandstone and impure limestone are inter-layered with sand in some places. Additionally, shells are common throughout this formation. Reportedly, this aquifer contains approximately 67 percent of permeable material, and the hydraulic conductivity is estimated to be 45-feet per day. The Black Creek confining unit lies below the Peedee aquifer and is approximately 48-feet thick in the vicinity of the site composed of clay, silty clay, and sandy clay containing 12 percent of permeable material. The underlying Black Creek aquifer is approximately 202-feet thick in the vicinity of the site and consists of thinly laminated gray to black clay inter-layered with gray and tan sands. Reportedly, this aquifer has a hydraulic conductivity of 35-feet per day and is composed of approximately 69 percent of permeable material. 4.0 RECENT ACTIVITIES CES has performed free product recovery activities and a limited groundwater monitoring event at the site in general accordance with NCDEQ correspondence dated November 22, 2022. 4.1 MONITORING WELL GAUGING Equilibrated static depth to water/product measurements were obtained on August 9, 2022 and again on October 10, 2022 using an electronic oil/water interface probe from all available monitoring/recovery wells (MW-2R, MW-3, MW-5R, MW-6R, MW-10, MW-11, MW-12, MW-13, MW-14R, MW-16, MW-17, MW-18, MW-19, MW-20, MW-21, MW-22, MW-23, TW-1, DW-1, RW-3, RW-6, and RW-7) unless otherwise noted. Monitoring well MW-7 cannot be located and monitoring wells MW-8 and MW-9 appear to have collapsed or otherwise suffered damage to the well screen or were inaccessible. Table 4 provides a summary of recent groundwater gauging and elevation data. 4.2 GROUNDWATER SAMPLING On October 10, 2022, CES mobilized to the site to conduct a limited groundwater sampling event. Samples were collected from monitoring/recovery wells MW-2R, MW-3, MW-5R, MW-6R, MW-12, MW-16, MW-17, MW-18, MW-19, MW-20, RW-3, RW-6, and RW-7. Monitoring well MW-7 was not sampled due to not being located. Prior to sampling, the monitoring wells were purged of at least three (3) well volumes, or until dry, using new disposable bailers. After purging, the necessary volume of water, groundwater samples were slowly poured from the bailer into laboratory provided containers pre-filled with appropriate preservatives, labeled with indelible ink, entered on the chain-of-custody, and immediately placed on wet ice in a chilled cooler maintained at approximately 4°C. Clean, disposable nitrile gloves were used during all phases of sample GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 7 handling. The samples were transported to Eurofins Environmental Testing located in Savannah, GA, a North Carolina certified laboratory for chemical analysis. The samples were analyzed for volatile organic compounds (VOCs) by Standard Methods 6200B. Purge volumes, sample times, and physical parameters recorded at the time of sampling are included on the groundwater sampling logs provided in Appendix B. 4.3 GROUNDWATER OCCURRENCE AND FLOW DIRECTION During the October sampling event, depth to groundwater measurements ranged from 1.95 (MW-12) to 5.02 (MW-14R) feet below top of casing in the shallow monitoring wells. Groundwater elevations were calculated based on monitoring well top-of-casing elevation data and ranged from 97.82-feet (MW-22) to 94.48-feet (MW-6R). A summary of groundwater gauging and elevation data from both events is presented in Table 4. Based on this data, shallow groundwater flow direction was interpreted to trend towards the north and east with a low in the area of monitoring wells MW-11 and MW-21 as illustrated on Figures 4A and 4B. The hydraulic gradient (i) was derived based on the October potentiometric map. The gradient was calculated based on the change in head over the horizontal distance between monitoring wells. MW-16 was utilized as the downgradient hottest well and MW-22 was utilized as the up-gradient location. Change in head (h): 97.82-feet (MW-22) to 95.35-feet (MW-16) = 2.47-feet Horizontal distance (L): 216.08-feet i = h/L = (2.47-feet/216.08-feet) = 0.0114 4.4 LABORATORY ANALYTICAL RESULTS Groundwater analytical results were compared to the groundwater quality standards defined in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Section .0202 (2L Standards) and the GCLs provided by the NCDEQ. The groundwater samples from monitoring/recovery wells MW-2R, MW-3, MW-6R, MW-12, MW-16, MW-17, MW-18, MW-19, MW-20, RW-3, RW-6, and RW-7 were reported to contain concentrations of dissolved petroleum contamination exceeding 2L Standards. The sample collected from recovery well RW-3 contained concentrations of TBA above the GCL of 10,000 µg/L. A tabulated summary of recent groundwater analytical results is presented in Table 5. A groundwater analytical results map is provided in Figure 5. Isoconcentration maps for benzene, ethylbenzene, xylenes, MTBE, and naphthalene are provided in Figure 6A through Figure 6E, respectively. The laboratory report and chain of custody documentation are provided in Appendix C. 4.5 FREE PRODUCT RECOVERY Measurable free product has been historically observed in monitoring/recovery wells MW-1, MW-2R, MW-4, MW-5, MW-5R, MW-6, MW-7, MW-11, MW-16, MW-17, RW-2, and RW-3. More recent field activities have revealed the presence of free product in monitoring wells MW-2R, MW-5R, MW-16, MW-17, MW-19, and MW-21 which has been observed to be dark brown to black in color indicating a weathered product. Hydrographs relating free product thickness and groundwater elevation vs time (since 2014) are included in Appendix D. Due to intermittent detections of free product in multiple wells at the site, a passive free product recovery method was employed. The product recovery method selected for the site was the Geotech Environmental Equipment, Inc. GeoSorb® selective product recovery system. The system consists of a stainless-steel mesh screen with ballast weight and sorbent sock. The ballast prevents vertical movement of the sock during fluctuations in groundwater elevation. The sock is constructed of polypropylene designed to sorb only product with minimal intake of water and is rated to hold approximately 0.18-gallons of product when GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 8 100% saturated. The sorbent sock is placed inside the screen ballast and suspended in the well such that the sock is centered within the depth to water which allows for maximum sorbent efficiency during water table fluctuations. During the August 2022 monitoring event, CES recovered the previously deployed socks and redeployed new GeoSorb® socks into monitoring wells MW-2R, MW-5R, MW-16, MW-17, and MW-21. Sorbent efficiency was estimated based on visual observation of percent saturation upon removal. An estimated 0.54-gallons of product was recovered by the sorbents during the monitoring period. Free product has historically been recovered by bailing, pumping, sorbents, and AFVR events. As of the date of this report, approximately 500-gallons of product has been recovered from the site since June of 1998. A summary of recent product thickness data is included in Table 4 and product recovery results are summarized in Table 6. Please refer to previous submittals for additional details. 4.6 ESTIMATED EXTENT OF CONTAMINATION Soil Soil sampling has not been performed at the site since UST Closure Activities in 2002. Based on historical soil analytical data, the extent of soil contamination above the maximum soil contaminant concentrations (MSCCs) is mostly confined to the site property and generally located on the southern side of the property in the area of the former UST basin and building totaling approximately 14,735 square feet. Maximum detected concentrations (MDCs) of COCs and the applicable cleanup goals for soil are summarized below in Exhibit 1.

Historically, free product has been detected in monitoring/recovery wells MW-1, MW-2R, MW-4, MW-5, MW-5R, MW-6, MW-7, MW-11, MW-16, MW-17, RW-2, and RW-3. More recent field activities have revealed the presence of free product in monitoring wells MW-2R, MW-5R, MW-16, MW-17, MW-19, and MW-21. The most recent occurrence of free product was 0.03-feet in monitoring well MW-5R on October 6, 2021. Groundwater GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 9 According to currently available data, groundwater contamination above cleanup criteria is throughout most of the site and extents to the south across East Fremont Street. The argument could be made that the contamination present in monitoring well MW-12 is from the previous release documented at the Brown’s Minute Mart site. During the most recent monitoring event, COCs in groundwater exceeded the 2L Standards at 12 of the 13 locations monitored and GCLs were only exceeded at one (1) location. The total currently known extent of groundwater contamination above 2L Standards comprises at least an approximate 24,000-ft2 area. The current maximum groundwater contaminant concentrations observed during the most recent reporting period compared to the historical maximum groundwater contaminant concentrations observed are summarized in Exhibit 2.

To determine contaminant mass, the average of total BTEX concentrations from all shallow monitoring well samples containing concentrations above 2L Standards (affected monitoring wells) were calculated. Estimated horizontal extents of total BTEX contamination in groundwater (as discussed above) were determined by each individual contaminant’s estimated isoconcentration areas as shown in Figures 6A through 6C (toluene concentrations did not exceed 2L Standards in any monitored location). Approximate volumes were then calculated utilizing the estimated areas, average thickness of contamination as determined from the average water column in each affected monitoring well, and the estimated effective GROUNDWATER MONITORING REPORT GPM 3059 (FORMER SCOTCHMAN #59) BURGAW, NORTH CAROLINA INCIDENT #19300 GPM 3059 (FORMER SCOTCHMAN #3059): GROUNDWATER MONITORING REPORT 10 porosity (0.04) as reported in the CSA. The volumes were then multiplied by the individual contaminant concentrations to obtain a mass of each BTEX constituent in the shallow portion of the surficial aquifer which was then converted to pounds (lbs.). Please note that this method assumes average isotropic concentrations of BTEX throughout the plume volume; therefore, this method presents a conservative estimate, and the actual BTEX may vary across different portions of the site. However, the method is effective for evaluation of trend data, expansion/contraction of the plume, and overall site remediation progress. More precise estimates may be obtained by completion of more comprehensive sampling at the site. The current estimated mass of BTEX in groundwater was calculated to be approximately 7.7 lbs. The contaminant mass calculations are included in Table 7. 5.0 CONCLUSIONS AND RECOMMENDATIONS 5.1 CONCLUSIONS The following conclusions are presented based upon the data and site-specific information collected and presented in this report: • Dissolved target compound concentrations were identified above 2L Standards and GCLs in multiple groundwater samples collected from the site in October 2022. • Free product was not encountered during the August 2022 gauging event or the October 2022 monitoring event. • In general, the occurrence of free product appears to be related to periods of above-average groundwater elevation. The trend data suggests a product smear zone may exist in soil above the average water table elevation. • The presence of free product contributes to the site’s risk ranking. 5.2 RECOMMENDATIONS CES recommends the following: • Continue monitoring the site through semi-annual groundwater sampling. • Perform an additional surfactant injection followed by AFVR events. • Perform free product checks with recovery as needed. • Once free product is determined to be absent and groundwater contaminant concentrations are demonstrated to be below GCLs, the site risk ranking should be re-classified and the incident considered for restrictive closure.

The report (revision 1) is being revised in order to report missing oxygenates for these samples. Receipt The samples were received on 10/24/2022 10:00 AM. Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 5.5°C GC/MS VOA Method SM6200_B: The laboratory control sample (LCS) for analytical batch 400-598451 recovered outside control limits for the following analyte: Bromomethane. This analyte was biased high in the LCS and was not detected in the associated samples; therefore, the data have been reported. Method SM6200_B: The laboratory control sample (LCS) for analytical batch 400-598937 recovered outside control limits for the following analyte: Acetone. This analyte was biased high in the LCS and was not detected in the associated samples; therefore, the data have been reported. Method SM6200_B: The following samples were diluted to bring the concentration of target analytes within the calibration range: MW-2R (680-223876-1), MW-6R (680-223876-4), MW-12 (680-223876-5), MW-16 (680-223876-6), MW-17 (680-223876-7), MW-19 (680-223876-9) and MW-20 (680-223876-10). Elevated reporting limits (RLs) are provided. Method SM6200_B: The result for m-Xylene & p-Xylene exceeded the linear range of the instrument for samples: MW-16 (680-223876-6). Reanalysis was performed outside of holding time. The original analysis is reported as primary and the reanalysis is reported as secondary for m-Xylene & p-Xylene. Method SM6200-B: Reanalysis of the following sample was performed outside of the analytical holding time due the initial calibration curve was outside acceptance criteria for 3,3-Dimethyl-1-butanol and ethanol: MW-16 (680-223876-6). The original analysis is reported as primary and the reanalysis is reported as secondary. Method SM6200_B: The laboratory control sample (LCS) associated with batch 400-598937 recovered above the upper control limit for Acetone. Reanalysis was performed outside of holding time. The original analysis is reported as primary and the reanalysis is reported as secondary for Acetone. Method SM6200-B: The laboratory control sample (LCS) and continuing calibration verification (CCV) associated for analytical batch 400-599283 recovered outside control limits for the following analyte: Ethanol. This analyte was added after the job was completed and reanalyzed outside of the analytical holding time, therefore the data has been reported. Method SM6200-B: The method blank for analytical batch 400-598988 contained Ethanol above the reporting limit (RL). This analyte was added after the holding time had expired, therefore the data has been reported. Method SM6200-B: The result for t-Butyl alcohol exceeded the linear range of the instrument for the following sample: RW-3 (680-223876-11). This analyte was added after the holding time had expired, therefore the data has been reported.
