EXECUTIVE SUMMARY
As required, the following executive summary provides the most pertinent information for this assessment.
For additional information please refer to subsequent sections of this report.
• CES of NC, PLLC (CES) was retained by GPM Southeast, LLC (GPM) to install three (3) new groundwater monitoring wells and complete groundwater monitoring activities in June 2022. The activities were directed in correspondence issued by the North Carolina Department of Environmental
Quality (NCDEQ) dated March 1, 2022. The services were provided in general accordance with the NCDEQ UST Section “Assessment Guidelines” and “Corrective Action Guidelines” under approved task authorizations 43177-8.
• A release was reported to the North Carolina Department of Environmental Quality (NCDEQ) on June
12, 2019 associated with a leaking product line beneath the diesel dispenser. Initial abatement activities,
a Limited Site Assessment (LSA), Risk Assessment Report (RAR), and additional assessment activities
were performed between July 2019 and October 2020.
• Soil and groundwater contamination at the site has been adequately delineated, but multiple receptors
are present within 1,500-feet of the source of the release. Impact to receptors has not been identified to
date.
• Free product has historically been detected at the site. To date, approximately 1.77 gallons of free
product has been recovered by a combination of aggressive fluid vapor recovery (AFVR) and sorbent
socks at an average cost of $3,667.51 per gallon.
• Groundwater flow direction was interpreted to trend generally towards the east.
• Based on increases of Contaminant of Concern (COC) concentrations in groundwater downgradient of the source, the groundwater contamination plume appears to be in an expanding state.
• The site maintains the criteria for “High” risk classification due to the presence of free product, potable
water supply wells located within 1,000-feet of the site, and a surface water body located within 500-
feet of the site.
• Based upon the risk classification, continued monitoring and corrective action is recommended.
• CES recommends continued maintenance of sorbent socks in monitoring well MW-1 and MW-2 until
free product is no longer detected. Additionally, AFVR or mobile multi-phase extraction is
recommended to address dissolved and adsorbed phase contamination near the source area and reduce
the potential for migration.
• Ultimately, monitored natural attenuation is recommended as the overall remedial strategy.

Comprehensive Site Assessment Report GPM 3323 (Scotchman No. 3323) 5325 South College Road Wilmington, North Carolina

GPM 3323 (SCOTCHMAN NO. 123) COMPREHENSIVE SITE ASSESSMENT REPORT 1
1.0 INTRODUCTION
The purpose of this report is to provide the details additional delineation activities associated with a release
from the diesel fuel underground storage tank (UST) system at the GPM 3323, also known as Scotchman No. 3323, facility located at 5325 South College Road, in Wilmington, North Carolina (site). A topographic map illustrating the site location is included as Figure 1. A release was reported to the North Carolina
Department of Environmental Quality (NCDEQ) on June 12, 2019 following routine inspection activities at site.
In correspondence dated March 1, 2022, the NCDEQ directed the responsible party, GPM Southeast, LLC (GPM), to complete a Comprehensive Site Assessment (CSA) Report for the site. GPM retained CES of NC, PLLC (CES) for environmental consulting services. The activities were provided in general accordance with the NCDEQ UST Section “Assessment Guidelines”. 2.0 SITE HISTORY AND CHARACTERIZATION
The site has operated a UST system since at least 1987. Historical UST system information and owner/operator and other responsible party information is provided in Tables 1 & 2. As required, the following provides information relevant to site history and characterization. 2.1 UST SYSTEM INFORMATION The UST system consists of five (5) single wall fiberglass reinforced plastic (FRP) tanks. Three (3) contain gasoline, one (1) contains diesel fuel, and the fifth contains kerosene. The tank pit is located in the southeast corner of the site as shown in Figure 2. There are two (2) pump islands, one (1) under the north end of the canopy and one (1) under the south end of the canopy, with two (2) double-sided dispenser units on each
island. A single kerosene dispenser is located at the southwest corner of the site convenience store building. The gasoline and kerosene USTs appear to be oriented in a general north-south direction and the diesel UST appears to be oriented generally perpendicular to the gasoline and kerosene USTs.

2.2 PAST RELEASES
No record of previous releases was found in the NCDEQ UST incident management database.

2.3 CURRENT FACILITY STATUS At the time of this assessment the facility is a fully functioning Scotchman branded gas station/convenience store with EXXON branded petroleum retail. According to GPM and based upon observation, the UST system is in operation. Improvements observed onsite include a one-story convenience store building, the pump islands, a former automated drive-thru car wash (currently out of service), and the associated paved parking areas. Pertinent site features are illustrated on Figure 2.
2.4 DESCRIPTION OF RELEASE, INITIAL ABATEMENT, AND HISTORICAL ASSESSMENT In June of 2019 Southern Pump & Tank Company (SPATCO) was calibrating meters at the facility when
they discovered petroleum beneath Dispenser 5/6 on the east end of the pump island under the south side of the canopy, the only dispenser with diesel product, which did not have a containment sump. That being the only diesel dispenser, it was shut down and bagged off. Petro Test tested the diesel line and found a
leak in the flex connector. A report was made by GPM to the NCDEQ of the release as required. SR&R Environmental removed the dispenser and pump island and excavated the impacted soils. Environmental Labs repaired the flex connector, installed a containment sump with sump sensor, and replaced the dispenser and pump island. On July 5, 2019 CES was onsite to conduct soil sampling for the Initial Abatement Action. CES sampled the excavation (BTM-1, SW-1, SW-2) and the stockpile of excavated soils (SS-1, SS-2). The samples were

GPM 3323 (SCOTCHMAN NO. 3323) COMPREHENSIVE SITE ASSESSMENT REPORT 2
submitted for analysis of Volatile Organic Compounds (VOCs), Semi Volatile Organic Compounds
(SVOCs), Extractable Petroleum Hydrocarbons (EPH), and Volatile Petroleum Hydrocarbons (VPH). The results reported that no parameter was above the NCDEQ Industrial/Commercial Cleanup Levels. (CES 2019) In an email dated October 1, 2019, the NCDEQ directed that a Limited Site Assessment (LSA) be conducted to determine if the release had impacted the groundwater at the facility. On November 6, 2019, CES mobilized a geologist, licensed driller, and a drill rig to the facility to conduct the LSA. A soil boring was advanced to a depth of fifteen (15) feet below ground surface (BGS) and a 2-inch inner diameter groundwater monitoring well was installed adjacent to the diesel dispenser. The report concluded that petroleum contaminated soil and groundwater was present at the site above regulatory limits and that the extent of contamination had not been defined. Additionally, the initial receptor survey identified multiple receptors within 1,500-feet of the site indicating that the site risk classification was high. In correspondence dated February 7, 2020, the NCDEQ directed the submittal of a Risk Assessment Report
(RAR) as an alternative to comply with the requirements of comprehensive site assessment. Due to delays experienced during the coronavirus disease 2019 pandemic, the RAR activities were not completed until May of 2020. Monitoring wells MW-2 through MW-4 and DW-1 were installed during the RAR activities.
During the assessment activities in May of 2020, free product was detected in monitoring well MW-1 which historically had not exhibited free product. Results of product typing analysis identified the product as diesel fuel; therefore, the product was determined to be from the recent release incident and a new release was not reported. Results of the RAR concluded that the extent of soil contamination was fully defined, but the horizontal extent of groundwater contamination had not been defined to the east and south of monitoring well MW-2. Historical soil sample data is summarized on Table 3 and Figure 4. Due to the detection of free product in the LSA monitoring well, MW-1, an initial aggressive fluid vapor recovery (AFVR) event was performed on June 16, 2020 as documented in the Free Product Recovery Report submitted July 2, 2020. Approximately 0.35-feet of free product was detected in monitoring well MW-1 prior to the AFVR event. The AFVR event consisted of extracting fluids and vapors from monitoring well MW-1 for a duration of approximately 8-hours, recovering approximately 0.30-equivalent gallons of petroleum as diesel fuel vapors and 1,650-gallons of petroleum impacted groundwater. Free product was observed to recharge into monitoring well MW-1 post-AFVR.
As part of additional assessment activities, two permanent monitoring wells (MW-5 and MW-6) were installed off-site on September 1, 2020 to delineate the extent of contamination. A limited monitoring event
consisting of sampling the newly installed monitoring wells, surface water creek adjacent to the site (SWS-1), and WSW-6 was performed on September 2, 2020. MW-1 was gauged for the presence of free product on a monthly basis between October 2020 and March 2021. Free product was detected on December 29, 2020 (0.01-feet) and February 16, 2021 (0.18-feet). The sorbent sock in MW-1 was replaced during each of these monthly gauging events. The sorbent sock in MW-1 was also replaced June 7, 2021, July 27, 2021, and September 10, 2021. A summary of free product recovery is presented in Table 8. A limited monitoring event consisting of sampling monitoring wells MW-1, MW-5, MW-6, and surface water creek adjacent to the site (SWS-1) was performed on January 5, 2022. MW-2 was not sampled due
to the presence of 0.36-feet of free product. A new sorbent sock was deployed in MW-1. Concentrations of benzene, naphthalene, tertiary-amyl alcohol (TAA), C5-C8 aliphatics, C9-C18 aliphatics, C19-C136 aliphatics, and C9-C22 aromatics were reported at or above the 2L Standards in the groundwater samples

collected from monitoring well MW-1. No exceedances of the GCLs were reported. The report concluded
that the vertical and horizontal extents of soil and groundwater contamination had been delineated, down gradient receptors did not appear to be impacted, and the site maintained the criteria for “High” risk classification. Continued monitoring and free product recovery were recommended. 2.5 SUBJECT SITE AND SURROUNDING PROPERTY USE Site and adjacent property owners/occupants are summarized in Table 4. Planning zones along the Carolina Beach Road and South College Road corridors and within the vicinity of the site generally consists of Highway Business (B-2) and Office and Institutional (O&I). Further from the business corridors lie properties zoned as Residential (R-15 and R-10). The site is zoned B-2. Surrounding Land use is depicted in Figure 3 (New Hanover 2020). The Site is utilized for commercial purposes with adjacent properties to the north and southeast also utilized as commercial properties. Adjacent properties to the northeast and east are generally wooded and zoned for Office and Institutional use, though residential structures appear to be present. To the west and southwest
are roads, NC-132 and US-421, respectively, beyond which are commercial properties. Surface cover at the site consists primarily of asphalt. Sparse vegetation is present along the perimeter of the Site. 2.6 REGIONAL GEOLOGY AND SITE HYDROGEOLOGY The State of North Carolina is divided into three physiographic provinces, The Coastal Plain, The Piedmont, and the Blue Ridge (NCDEQ 2015). According to the September 29, 2015 “Geologic Map of North
Carolina” the site is located within the Atlantic Coastal Plain Province and more specifically in the Tidewater region of the Coastal Plain (NCPEDIA 2012). The Coastal Plain is characterized by flat land to gently rolling hills and valleys. Elevations range from sea level near the coast to about 600 feet in the Sandhills of the southern Inner Coastal Plain; It covers about 45% of the land area of the State. The surficial aquifer beneath the site is comprised of Pleistocene and Pliocene age sediments and is estimated to be approximately 83-feet thick. During drilling activities at the site, saturated sediments were encountered between approximately three (3) to eight (8) feet BGS. Equilibrated depth to groundwater in the site monitoring wells typically ranges from approximately 4- to 8-feet BGS. 3.0 RECEPTOR INFORMATION
CES evaluated potential receptors based on historically available information and current site conditions as discussed below. A receptor survey was originally performed during LSA activities and updated during RAR activities and subsequent site visits. 3.1 WATER SUPPLY WELLS According to the records of the NCDEQ Division of Water Resources (DWR) Source Water Assessment Program (SWAP) mapping application (NC DEQ 2018) and the Environmental Health Services (EHS) of
the New Hanover County Health Department (Zuncich 2019) there is one permitted Transient Non-Community water supply well (WSW) within 1,500 feet of the property. This well is located approximately 1,130 feet northwest of the property, and is designated PWS 7065018, State Well ID 501. Based upon
records from New Hanover Environmental Health and previous reports by other consultants, four (4) additional private wells have also been reported within that 1,500-foot radius of which one (1) appears to not be in use (ES&S 2012).
As part of RAR activities, CES sent water supply well questionnaires via certified mail to the owner(s) of all properties which were historically reported to contain water supply wells and all properties within 500-feet of the source area of the release as identified by New Hanover County tax assessor records. At the time

GPM 3323 (SCOTCHMAN NO. 3323) COMPREHENSIVE SITE ASSESSMENT REPORT 4
of the RAR, delivery confirmation was available for eleven (11) of the thirteen (13) water supply well
questionnaires. Of the eleven (11) delivered water supply well questionnaires, seven (7) responses to the requests for information were received. Refer to previous submittals for copies of the returned water supply well surveys and associated certified mail receipts. Please note that although 5315 S College Road was initially reported to obtain drinking water from a supply well, subsequent discussion with the property owner and property reconnaissance confirmed that a well does not currently exist on this property for purposes of drinking water or irrigation (Hobbs 2020). CES subsequently conducted a visual site reconnaissance within 1,500-feet of the site to identify the existence of suspect water supply wells or other potential receptors. Water supply wells were visually confirmed at five (5) properties within 1,500-feet of the site. Additionally, water meters and/or fire hydrants were observed in the vicinity of the site suggesting municipal water is available to the area. During subsequent monitoring activities, WSW-8 was reported to be out of service and the associated residence connected to municipal water.
A list of potential receptors based on historical sources, publicly available information, the water supply well surveys, and the visual reconnaissance is presented in Table 5. Based on this data, eight (8) water supply wells are present within 1,500-feet of the site as illustrated on Figure 3. Of these wells, only WSW-
1 and WSW-6 are reported to be actively utilized for potable purposes within 1,000-feet of the site. Wells used for non-potable purposes (i.e. irrigation) do not exist within 500-feet of the site. 3.2 PUBLIC WATER SUPPLIES According to the Cape Fear Public Utility Authority (CFPUA), municipal water is available and services most of the properties within 1,500 feet of the source area. The source of water for this area is the Sweeney Water Treatment Plant which obtains water from a surface water source (Cape Fear River) operating as PWS ID NC0465010. Please refer to documentation included in previous submittals. However, two (2) properties were reported to utilize water supply wells as a source of potable water as noted above. 3.3 SURFACE WATER The site reconnaissance and map review located three natural surface water bodies within 1,500 ft. of the site including two unnamed intermittent tributaries of Mott Creek, one to the east and one to the north at approximately 200 and 500 feet from the site, respectively. Mott Creek (Todds Creek) is approximately
1,200 feet north of the property and has a classification of Class C: Swamp Water (C:Sw). Additionally, a man-made retention pond for stormwater control is located approximately 500-feet south of the site. The locations of the surface water bodies are presented in Table 5 and illustrated on Figure 3.
3.4 WELLHEAD PROTECTION AREA The site is reportedly not located within an approved wellhead protection area as defined by 42 USC 300h-
7(e). 3.5 SUBSURFACE STRUCTURES Storm water flow at the site is routed to ditches and drainage structures within the North Carolina Department of Transportation (NCDOT) rights-of-way of College Road and Carolina Beach Road. Municipal water and sewer lines are located within the Clayton Horn Dairy Road, Carolina Beach Road,
and South College Road rights-of-way. Subsurface utility lines on-site include sanitary sewer lines, water service lines, and private electrical lines. The locations of on-site subsurface utilities identified by private locator prior to drilling activities are illustrated on Figure 2. The locations of site vicinity subsurface utilities provided by the CFPUA are shown on Figure 3.

3.6 DEEP AQUIFERS IN THE ATLANTIC COASTAL PLAIN PROVINCE
The site is located within the Tidewater region of the Atlantic Coastal Plain Province. The first four aquifers that lie within New Hanover County, in descending order, include:
• Surficial aquifer comprised of Pleistocene and Pliocene age sediments;
• Castle Hayne confining unit and aquifer with sediments generally of Eocene age;
• Peedee confining unit and aquifer which is comprised of Late Cretaceous age sediments, and
• Black Creek confining unit and aquifer which is comprised of Late Cretaceous age sediments. Surficial aquifer sediments in the Tidewater region were deposited under shallow marine or estuarine
conditions. These consist of fine sand, silt, clay, shell, peat beds, and scattered deposits of coarser-grained material in the form of relic beach ridges and floodplain alluvium. The aquifer is composed of 79 percent permeable material and has an estimated hydraulic conductivity of 35 feet per day. The surficial aquifer is approximately 83 feet thick in the vicinity of the site. The underlying Castle Hayne confining unit is composed of beds of clay, sandy clay, and clay with sandy streaks. Throughout much of New Hanover County, the Castle Hayne confining unit is thin, with an average thickness of about 14 feet, and contains enough sand to allow significant vertical movement between the surficial aquifer and the underlying Castle Hayne aquifer. The Castle Hayne confining unit is approximately 17 feet thick in the vicinity of the site.
The Castle Hayne aquifer is predominantly composed of limestone (including shell, dolomitic, and sandy limestone ranging from loosely consolidated to hard/crystallized) and sand with minor amounts of clay. Sand bed intervals have varying carbonate content and range from fine to coarse-grained. Clay occurs as
marl beds less than 10 feet thick or as a matrix in both sand and limestone beds. The upper portion of the Castle Hayne aquifer typically consists of limestone and the lower portion consists of unconsolidated sand. The Castle Hayne aquifer is approximately 26 feet thick in the vicinity of the site. The aquifer contains
approximately 90 percent permeable material. The estimated hydraulic conductivity is 25 feet per day. The Peedee confining unit is overlain by the Castle Hayne aquifer in New Hanover County. The Peedee confining unit is approximately 19 feet thick in the vicinity of the site and consists of clay, silty clay and sandy clay and represents the Cenozoic-Mesozoic geological boundary. The underlying Peedee aquifer is approximately 355 feet thick at the site and has an estimated hydraulic conductivity of 65 feet per day. Sediments of the Peedee Formation consist of fine to medium-grained sand interbedded with gray to black marine clay and silt. Glauconitic sand beds and thin beds of consolidated sandstone and impure limestone are interlayered in the sands. The Black Creek confining unit is overlain by the Peedee aquifer. The Black Creek confining unit is
reportedly 80 feet thick at the site and contains sediments having less than 12 percent permeability. The Black Creek aquifer, overlain by the Black Creek confining unit, has a thickness of 156 feet and an estimated hydraulic conductivity of 25 feet per day.

• MEDAC Urgent Care, approximately 900 feet northeast, business district. 4.0 SOIL ASSESSMENT
Soil sampling has not been performed since initial abatement and monitoring well installation activities
between July 2020 and March 2021. Historically, soil contamination has been identified proximal to the diesel dispenser and monitoring well MW-1 and appears to extend vertically from approximately 2 to 3 feet BGS to the top of the water table. It is likely that the horizontal extent of soil contamination may extend into the active UST pit. The estimated extent of soil contamination is considered to be approximately 300 square feet in the vicinity of monitoring well MW-1 and the diesel dispenser extending to a depth between approximately 3 to 8-feet BGS, inclusive of the groundwater smear zone. The available soil analytical data
are presented in Table 3 and on Figure 4. 5.0 GROUNDWATER ASSESSMENT
CES performed the following assessment activities throughout the reporting period in accordance with the
NCDEQ pre-approval task authorization (PATA) 43177-8. Copies of the PATA and relevant correspondence are included in Appendix A. 5.1 GROUNDWATER MONITORING WELL INSTALLATION One June 17, 2022, CES mobilized to the site to oversee the installation of three (3) groundwater monitoring wells (MW-7, MW-8 and MW-9). The groundwater monitoring wells were installed by Bridger Drilling with a track-mounted drill rig using direct push techniques. Groundwater monitoring wells were installed to collect groundwater samples and to monitor for the presence of free product. Groundwater monitoring wells were constructed using 2-inch inner diameter schedule 40 polyvinyl chloride (PVC) casing and 0.010-inch factory-slotted well screen. Each well is equipped with an expansion-type locking well cap. Well construction was completed subsequent to removal of the drill rods. The well annulus was filled with washed, #2 quartz filter sand to a minimum depth of approximately one foot above the top of the screened interval. A pelletized bentonite seal was placed above the sand filter pack and hydrated with potable water.

GPM 3323 (SCOTCHMAN NO. 3323) COMPREHENSIVE SITE ASSESSMENT REPORT 7
The remainder of the annulus was completed with neat portland grout and a flush-mount protective well
cover cemented at the ground surface. Monitoring well construction diagrams are included as Appendix B. 5.2 GROUNDWATER OCCURRENCE AND FLOW DIRECTION On June 25, 2022, CES performed a groundwater gauging event utilizing site monitoring wells MW-1, MW-2, MW-4, MW-6, MW-7, MW-8, MW-9, and DW-1. At this time, depth to groundwater in the shallow Type II monitoring wells was measured to range from 5.54-feet below top of casing (TOC) (MW-4) to 9.31-feet below TOC (MW-9). Free product was in MW-1 (0.03-feet) and MW-2 (0.60-feet). Groundwater elevations in the shallow monitoring wells relative to an arbitrary benchmark with an assumed elevation of 100.00 feet (MW-1 TOC) ranged from 93.66 feet (MW-4) to 84.96 feet (MW-6). Based on this data, shallow groundwater flow direction was interpreted to trend generally towards the east/northeast with an average hydraulic gradient of 0.0119 (MW-4 to MW-2) as shown on Figure 5. Based on more complete historic groundwater information, overall groundwater flow is believed to trend towards the east, in the direction of the unnamed tributary of Mott Creek. The deeper screened interval Type III well
DW-1 was excluded from shallow groundwater flow direction evaluation. A summary of groundwater gauging and elevation data is included in Table 10. The groundwater elevations were corrected for the presence of free product, where encountered, using an assumed relative density of 75%. 5.3 GROUNDWATER SAMPLING A water sampling event was performed on June 25, 2022. Water samples were collected from MW-4, MW-
6, MW-7, MW-8, MW-9, DW-1 and the creek surface water body (SWS-1). Equilibrated static depth to water in the monitoring wells was measured with an electronic oil/water interface probe and monitoring well purge volumes were calculated. Monitoring wells MW-1 and MW-2 contained free product and were not sampled. The sorbent sock in MW-1 was observed to not be fully saturated and was placed back in the well to continue collecting product. A new sorbent sock was deployed in MW-2. Free product was not manually recovered during this sampling period. Prior to sampling, a minimum of three (3) well volumes were purged from each monitoring well using a dedicated, disposable polyvinyl chloride bailer and nylon cord. The bailer was gently lowered into the well and allowed to fill with water, then raised to the surface and evacuated. This process was repeated until the necessary volume of water had been removed from the monitoring well. Water supply well WSW-6 had no
power and was not sampled. Surface water was sampled by collecting a grab sample from the flowing creek. Prior to and at completion of monitoring well purging, groundwater physical parameters were recorded
using a groundwater multi-parameter meter. After purging the necessary volume of water from the monitoring wells, groundwater samples were collected by slowly pouring from the bailer to reduce volatilization. Surface water samples were collected by directly immersing the sample bottles in the water
and allowing them to fill by gravity flow, taking care to prevent overfilling of the containers. All samples were contained in laboratory provided containers pre-filled with appropriate preservatives, labeled with indelible ink, entered onto a chain-of-custody form, and immediately placed on wet ice in a chilled cooler maintained at a temperature of approximately 4° C. The samples were transported under chain-of-custody protocol and submitted to Pace Analytical Services, LLC located in Mount Juliet, TN for chemical analysis. The groundwater samples were analyzed for volatile organic compounds (VOCs) by Standard Methods 6200B, semi volatile organic compounds (VOCs) by Standard Method 625.1, and both volatile petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH) by Massachusetts Department of Environmental Protection (MADEP) methods.

5.4 GROUNDWATER ANALYTICAL RESULTS
Water sample analytical results were compared to the groundwater quality standards defined in Title 15A of the North Carolina Administrative Code, Subchapter 02L, Section .0202 (2L Standards), gross contamination levels (GCLs) provided by the NCDEQ, and the surface water quality standards defined in Title 15A of the North Carolina Administrative Code, Subchapter 02B (2B Standards). The laboratory analytical report is provided in Appendix C with analytical detections of constituents of concern (COCs) summarized in Table 9 and on Figure 6. Concentrations of benzene, naphthalene, n-propylbenzene, C5-C8 aliphatics, C9-C22 aromatics were reported at or above the 2L Standards in the groundwater samples collected from monitoring well MW-9. Concentrations of benzene were reported at or above the 2L Standards in the groundwater samples collected from monitoring well MW-7. Isoconcentration maps for constituents detected above 2L Standards are included as Figures 7A-7E. No exceedances of the GCLs were reported. Please refer to the laboratory analytical report for the complete
analytical suite. The surface water sample SWS-1 was reported to be below laboratory reporting limits or the 2B Standards
for all analytes. 5.5 INVESTIGATIVE DERIVED WASTE
Groundwater generated from the monitoring well purging and sampling activities was disposed of by spreading on-site as a “deemed permitted” waste. 5.6 QUALITY ASSURANCE & QUALITY CONTROL To reduce the potential of cross contamination, dedicated disposable nitrile gloves were worn during all phases of soil and groundwater sample handling. Field monitoring equipment such as organic vapor analyzers and water quality instruments were calibrated to manufacturer specifications prior to each day of use. Drilling tools were decontaminated between boring locations using a steamer pressure washer with potable water. Hand augers were decontaminated between sampling locations using a three-stage rinse-wash-rinse procedure utilizing non-phosphate detergent and potable water. All samples were maintained under strict chain-of-custody protocol as documented in Appendix C.
As part of CES’s quality assurance and quality control (QA/QC) measures, a data review of the laboratory report was conducted. During the review, it was found that the samples were received by the laboratory in
acceptable condition and properly preserved. The samples were analyzed within applicable holding times and the chain-of-custody was properly completed by all parties. The laboratory QC report shows that an internal blank was analyzed for each method that was used for the original samples. The laboratory method
blank, laboratory control sample, and associated matrix spike and matrix spike duplicate data results were also provided for each analytical method. Refer to Appendix C for details regarding QA results for the laboratory samples and any noted exceptions. Overall, CES concludes that the laboratory results are of sufficient quality for use in this assessment and any exceptions do not significantly impact the conclusions presented in this report. 6.0 FREE PRODUCT ASSESSMENT
Free product has been observed in monitoring wells MW-1 with thicknesses ranging from 0.52-feet (July 23, 2020) to 0.03-feet (June 25, 2022), and in MW-2 with thicknesses of 0.36-feet (January 5, 2022) and 0.60-feet (June 25, 2022). During the most recent groundwater sampling event on June 25, 2022, free product was observed at MW-1 (0.03-feet) and MW-2 (0.60-feet).

GPM 3323 (SCOTCHMAN NO. 3323) COMPREHENSIVE SITE ASSESSMENT REPORT 9

Free product recovery efforts have included an AFVR event at MW-1 on June 16, 2020, hand bailing of product, and use of sorbents to passively recover product. To date, an estimated total of 1.77 gallons of product have been recovered. Free product recovery results are summarized in Table 8. The estimated extent of free product is included on Figure 9. 7.0 HYDROGEOLOGIC EVALUATION
CES conducted falling and rising head slug tests at monitoring wells MW-1 and MW-2 to obtain data necessary in the calculation of aquifer characteristics including hydraulic conductivity, transmissivity, and flow velocity. Following the recording of the pre-test static water level, a sealed, weighted cylinder or a slug was introduced into the well, facilitating an increase in the water level. The recovery to static water level was recorded using a Mini-TrollTM Environmental Data Logger equipped with a submersible pressure transducer. Subsequent to equilibration, the slug was extracted from the well with one rapid motion; the corresponding recovery also was recorded with the data logger. Slug test data and graphic representations
obtained during the investigation are provided as Appendix D. The slug test data were used to calculate hydraulic conductivity using AqtesolvTM aquifer test software developed by Geraghty and Miller (1989). AqtesolvTM utilizes several methods for calculating hydraulic conductivity from slug and pumping tests. For this investigation, CES used the Bouwer and Rice method for determining hydraulic conductivity in un-confined aquifers (Bouwer and Rice, 1976), which consists of
the following equation: 2KLt Inso - Inst = re rc2ln(---)
rw
Where: so= initial drawdown in well due to instantaneous removal of water from well st= drawdown in well at time t L= length of well screen rc= radius of well casing ln(re/rw)= empirical Ashape factor@ determined from tables provided in Bouwer and
Rice (1976) re= equivalent radius over which head loss occurs
rw= radius of well (including gravel pack) The rising head slug tests performed on MW-1 and MW-2 yielded calculated hydraulic conductivity values of 1.6053 feet per day (ft/day) and 0.6414 ft/day, respectively. An average value of 1.1233 ft/day was utilized for further calculations and modeling to represent offsite conditions. Transmissivity was calculated using the following equation (Freeze and Cherry, 1979):

GPM 3323 (SCOTCHMAN NO. 3323) COMPREHENSIVE SITE ASSESSMENT REPORT 10
T=Kb
Where: T = transmissivity K = hydraulic conductivity b = saturated thickness of the aquifer The saturated thickness of the initial water bearing zone is presumed to be 83-feet. The calculated K value of 1.123 ft/day is presumed to be the estimated hydraulic conductivity of the water bearing interval encountered at the subject site. A transmissivity value of 93.2256 ft2/day is estimated. Groundwater velocity is calculated using the following equation: V = KI/ne
Where: K = hydraulic conductivity
I = hydraulic gradient ne = effective porosity
The estimated hydraulic gradient across the site on June 25, 2022, was 0.0098 feet per feet (ft/ft), determined from the potentiometric surface map depicted on Figure 5. The assumed effective porosity value of 40% for a silt and fine sand mixture, as reported during drilling activities, was obtained from the AQTESOLV website (AQTESOLV 2020). Groundwater velocity at the site is calculated to be 0.02752 feet per day (ft/day), or 10.046 feet per year (ft/yr). 8.0 SITE SPECIFIC GEOLOGY AND HYDROLOGY
Soils at the site consists of sands and clays. During the advancement of the soil boring for the LSA, sand and gravel fill was encountered for the first two feet below the asphalt pavement. Next, a gray medium to fine sand was encountered and continued to a depth of 13 feet BGS. Below the sand a dark gray silty, slightly sandy marine clay was encountered to the bottom of the boring at 15 feet. The primary soil type identified during RAR and subsequent drilling activities was silty sand, and the effective porosity is estimated to be approximately 40%. A confining layer of stiff clay was reported at approximately 40-feet BGS. Geologic cross sections are presented in Figures 8A and 8B. Site hydraulic conductivity was estimated by performing slug tests in monitoring well MW-1 and MW-2. Based on this data, the average site hydraulic conductivity was estimated to be 1.123-feet per day, the transmissivity was calculated to be 93.24 square feet per day, and the seepage velocity was calculated to be
approximately 10.05-feet per year.

9.0 CONCLUSIONS AND RECOMMENDATIONS
9.1 CONCLUSIONS Based upon the results in this monitoring report, CES has developed the following conclusions:
• The occasional presence of free product, water supply wells used for potable purposes within 1,000-feet of the site, and a surface water body within 500-feet of the site contribute to the site’s risk ranking.
• The vertical and horizontal extents of soil and groundwater contamination have been delineated.
• The down gradient receptors do not appear to be impacted.
• The site currently maintains the criteria for “High” risk classification. 9.2 RECOMMENDATIONS CES has developed the following recommendations for this site:
• Based upon the risk classification, continued monitoring and corrective action is recommended.
• Product sorbents should continue to be utilized in monitoring well MW-1 and MW-2 as an interim passive free product recovery method until free product is no longer detected.
• AFVR or mobile-multi phase extraction is recommended to address dissolved and adsorbed phase contamination near the source area to reduce the potential for migration.
• Based on the limited extent of contamination, semi-annual monitored natural attenuation is recommended as the overall remedial strategy.

Re: Notice of Regulatory Requirements
15A NCAC 2L .0407(c) [High Risk]
Risk-based Assessment and Corrective Action
For Petroleum Underground Storage Tanks

Scotchman #3323
5325 S. College Road
New Hanover County
Incident Number: 43177
Risk Classification: High
Ranking: H120D

Dear Mr. Lann:

The Annual Monitoring Report received on February 23, 2022 has been reviewed by the UST
Section, Division of Waste Management, Wilmington Regional Office. The risk posed by the discharge or
release at the subject site is classified by the Department of Environmental Quality as high, as stipulated
under Title 15A NCAC 2L .0406. The land use at the site is classified as residential. Title 15A NCAC 2L
.0407(a) requires you to notify the Department of any changes that might affect the risk or land use
classifications that have been assigned.
Title 15A NCAC 2L .0407(c) [High Risk] requires you to comply with the assessment and cleanup
requirements of Title 15A NCAC 2N .0706 and Title15A NCAC 2L .0106(c) and 2L .0106(g). A
Comprehensive Site Assessment (CSA) Report prepared in accordance with these requirements and the
most recent version of the UST Section Assessment Guidelines must be received by this office within 90
days of the date of this notice. In addition, you must submit a summary of the CSA Report to the local
Health Director and the local Chief Administrative Officer in accordance with 15A NCAC 2L .0114. The
summary should be submitted to these persons no later than five working days after submittal of the CSA
Report to this office.
Failure to comply in the manner and time specified may result in the assessment of civil
penalties and/or the use of other enforcement mechanisms.

North Carolina Department of Environmental Quality | Division of Waste Management
Wilmington Regional Office | 127 Cardinal Drive Extension | Wilmington, NC 28405 |

An extension to this deadline may be obtained through the completion and submittal of an
Accelerated Site Characterization (ASC) Report prior to the completion of the CSA. The scope of work
defined by the ASC Report consists of generating an updated conceptual site model based upon real-time
field screening using high-resolution site characterization practices. In this process the vertical and
horizontal extent of soil and ground water contamination onsite may be quickly evaluated to reduce the
number of iterative steps necessary to complete plume delineation and allow for the creation of a more
accurate comprehensive soil and ground water assessment and monitoring network plan to improve the
quality and reduce the costs of the subsequent CSA Report.
Effective October 1, 2004, the Department of Environmental Quality requires that all work not
determined to be an emergency response or associated with risk assessment (i.e., the Limited Site
Assessment Report, per Title 15A NCAC 2L .0405) must be preapproved if State Trust Fund reimbursement
is anticipated. To comply with this requirement, a completed Preapproval/Claim Authorization Form,
encompassing the required remedial activities, must be received in this office within 14 days of the date of
this letter. Upon completion of the preapproved activities, you should submit your claim promptly.
Reimbursement funds are budgeted based on completed preapprovals, but delays in reimbursement or even
denial due to exceeding the statute of limitations on claiming eligible costs can result where claims are not
submitted immediately following work completion.
Because a release or discharge has been confirmed, a Licensed Geologist or a Professional
Engineer, certified by the State of North Carolina, is required to prepare and certify all reports submitted to
the Department in accordance with 15A NCAC 2L .0103(e) and 2L .0111(b).
If you have any questions regarding trust fund eligibility or reimbursement from the Commercial
Leaking Petroleum Underground Storage Tank Cleanup Fund, please contact the UST Section Trust Fund
Branch at [phone]. If you have any questions regarding the actions that must be taken or the rules
mentioned in this letter, please contact me at the address or telephone number listed below.
Sincerely,

Rhonda Olson
Hydrogeologist

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.
[Preliminary Report]

Project Manager
Sample Delivery Group (SDG) Narrative
An aliquot for analysis was taken from the original container received due to the level of sediment present in the sample.
Rinsing of the original sample container for inclusion in the sample extraction was not performed.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J2 Surrogate recovery limits have been exceeded; values are outside lower control limits.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
V The sample concentration is too high to evaluate accurate spike recoveries.
