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 complete a limited groundwater monitoring event. The activities were requested in a “Notice of Regulatory Requirements” dated August 30, 2023, issued by the North Carolina Department of Environmental
Quality (NCDEQ). The services were provided in general accordance with the NCDEQ Underground Storage Tank (UST) Section “Assessment Guidelines” and “Corrective Action Guidelines”.
• Historical site activities include a Site Check and Initial Abatement Activities, a Limited Site Assessment (LSA), a Comprehensive Site Assessment (CSA), and multiple groundwater monitoring events. The previous groundwater monitoring event was performed in June of 2023, which indicated groundwater contamination remained above regulatory standards.
• CES personnel mobilized to the site on November 3, 2023, for completion of a limited groundwater monitoring event. Monitoring wells MW-1RA, MW-2, MW-3, MW-4, and MW-5 were sampled for volatile organic compounds (VOCs) by Standard Method 6200B. Free product was not encountered during the November 2023 monitoring event.
• Groundwater samples collected from site monitoring wells indicated groundwater impacts that exceeded the groundwater quality standards defined in Title 15A of the North Carolina Administrative Code (NCAC), subchapter 2L, Section .0202 (2L Standards) in monitoring wells MW-1RA, MW-3, MW-4, and MW-5 for benzene, toluene, ethylbenzene and xylenes (collectively
referred to as “BTEX”), methyl tert butyl ether (MTBE), and naphthalene. Samples from the November 2023 groundwater sampling event did not exceed the applicable gross contamination levels (GCL).
• Groundwater flow was generally interpreted to flow overall towards the south with an estimated horizontal hydraulic gradient of 0.0128 feet/foot during the November 2023 sampling event.
• The contaminant mass of BTEX is estimated to be 40.1 lbs.
• In conclusion, CES will complete the requested NCDEQ soil excavation activities and recommends conducting semi-annual groundwater monitoring for an additional year to monitor seasonal fluctuations and distribution trends.

GROUNDWATER MONITORING REPORT ROADRUNNER #135 BLACK MOUNTAIN, NORTH CAROLINA INCIDENT #28783
ROADRUNNER #135: GROUNDWATER MONITORING REPORT 1
1.0 INTRODUCTION
The purpose of this report is to provide the details of groundwater monitoring activities associated with an
assumed release from a UST system at the Roadrunner #135 facility located at 202 NC Highway 9 in Black Mountain, North Carolina (site). The release was confirmed to the NCDEQ on December 3, 2009 and assigned Incident number 28783.
In correspondence dated August 30, 2023, the NCDEQ directed the responsible party, GPM, to proceed with groundwater monitoring activities. GPM retained CES for these environmental consulting services. The services were provided in general accordance with the NCDEQ UST Section “Assessment Guidelines” and “Corrective Action Guidelines”. 2.0 SITE HISTORY AND CHARACTERIZATION
Historically, the site has been owned and operated by Mountain Empire Oil Company (the predecessor by merger of GPM Southeast, LLC, known as GPM). The site has operated a UST system since at least 1990. Historical UST system information and owner/operator and other responsible party information is
summarized in Tables 1 & 2. As required, the following provides information relevant to site history and characterization. Detailed site history and characterization has been provided in previous reports.
2.1 SITE LOCATION The site is located at the southwest corner of the intersection of NC Highway 9 and Vance Avenue in Black Mountain, Buncombe County, North Carolina. Figure 1 is a topographic map depicting the site location and Figure 2 is a site map illustrating pertinent site features. The site vicinity is shown on Figure 3. 2.2 CURRENT FACILITY STATUS The property is owned by BMRR, LLC and is operated by GPM as Roadrunner #135, a convenience store and Shell-branded retail petroleum fuel outlet, which currently maintains three (3) 10,000-gallon gasoline USTs. GPM owns and operates the current registered USTs. According to GPM and based upon observation by CES personnel, the current UST system is in operation.
Improvements on site include a one-story convenience store building, four (4) double-sided petroleum product dispensers, and associated canopy with paved parking areas. 2.3 SITE HISTORY Mountain Environmental conducted Site Check soil boring and sampling activities at the site on November 12, 2009. Sampling activities were conducted as a result of an NCDEQ directive included with correspondence from Ms. Ter Spinner dated October 6, 2009. As part of the Site Check activities, five (5) soil samples were collected from locations around the UST basin on November 12, 2009. These samples
were collected from soil at a depth of approximately 3 to 5-feet below ground surface (bgs). All samples for this event were submitted for gasoline range organics (GRO) analysis. Results ranged from below reportable limits in sample S-5 to 5,030 mg/kg in sample S-4. An Initial Abatement Activities Report
(IAAR) was submitted in September 2010. Groundwater monitoring well MW-1 was installed as part of Limited Site Assessment (LSA) activities on
October 5, 2010. A subsequent soil sample immediately adjacent to MW-1 was collected from just above the water table on October 12, 2010. This sample was analyzed for volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method 8260 and for volatile petroleum hydrocarbons (VPH) by the Massachusetts Department of Environmental Protection (MADEP) Method. Results indicated that VOC and VPH parameters exceeded the soil to groundwater maximum soil contaminant concentrations (MSCCs).
GROUNDWATER MONITORING REPORT ROADRUNNER #135 BLACK MOUNTAIN, NORTH CAROLINA INCIDENT #28783
ROADRUNNER #135: GROUNDWATER MONITORING REPORT 2
A groundwater sample was collected from monitoring well MW-1 on October 18, 2010. The sample was
analyzed for VOCs by EPA Method 6200B. Results indicated that ten (10) VOC parameters exceeded the groundwater quality standards defined in Title 15A of the North Carolina Administrative Code (NCAC), subchapter 2L, Section .0202 (2L Standards). In addition, benzene and methyl-tert-butyl ether (MTBE)
exceeded the GCLs at concentrations of 8,930 micrograms per liter (µg/L) and 47,800 µg/L, respectively. The LSA Report was submitted on November 30, 2010. Based on the receptor survey conducted as part of the LSA activities, the site was classified as an intermediate risk site due to the proximity of the Swannanoa River and the on-site dissolved benzene concentration exceeding the surface water standard by a factor of 10. As part of the Comprehensive Site Assessment (CSA) activities, an additional eight (8) monitoring wells, MW-2 through MW-9, were installed to assess the dissolved petroleum impact in groundwater at the site. Soil samples were collected at the five-foot sampling intervals for each monitoring well and analyzed for VOCs and VPH. VOCs were detected in the first five-foot interval from the borings for monitoring wells
MW-3 and MW-4. All other samples were below applicable standards. Groundwater sampling conducted for monitoring wells MW-1 through MW-9 on September 29, 2011, indicated VOC and VPH analytes present above the 2L Standards in MW-1, MW-3, MW-4, MW-5, and MW-6. The CSA Report was
submitted to NCDEQ on November 11, 2011. Historic soil data is summarized in Table 3 and depicted in Figure 4.
Multiple groundwater monitoring events have been conducted at the site since 2012 with free product occasionally present in monitoring well, MW-5. The previous groundwater monitoring event was performed in June of 2023 in which groundwater contamination remained above the 2L regulatory standards in MW-1R, MW-3, MW-4, and MW-5.
2.4 SITE GEOLOGY AND HYDROGEOLOGY The subject site is located in the Inner Piedmont Physiographic Province of western North Carolina. Mountain Environmental reviewed the Geologic Map of North Carolina (NC Department of Natural Resources and Community Development – 1985) for information regarding site bedrock geology. Bedrock at the subject property consists of rocks from the Asheville Metamorphic Suite. Rock types include ‘Metagraywacke – foliated to massive, locally conglomeratic; interlayered and gradational with mica schist,
muscovite-biotite gneiss and rare graphitic schist.’ Bedrock was not encountered during drilling activities. As reported in the CSA, the horizontal groundwater seepage velocity ranged from 0.019 feet per day (ft/day)
to 0.027 ft/day. This was estimated based upon an effective porosity of 0.35 and a hydraulic conductivity range of 0.52 to 0.74 ft/day. Hydraulic conductivity was determined through a series of rising head slug tests performed in monitoring wells, MW-3 and MW-5 and evaluated with the Bouwer and Rice equation.
These calculated hydraulic properties are indicative only of the areas immediately adjacent to the tested wells and may not reflect conditions throughout the upper portion of the regional aquifer, nor do they describe aquifer characteristics of the competent bedrock beneath the site.
3.0 POTENTIAL RECEPTOR INFORMATION
Potential receptors were evaluated based on available information and current site conditions as discussed below. Receptor information is summarized in Table 4 with receptor identification and location tied to the
site vicinity map included as Figure 3.
GROUNDWATER MONITORING REPORT ROADRUNNER #135 BLACK MOUNTAIN, NORTH CAROLINA INCIDENT #28783
ROADRUNNER #135: GROUNDWATER MONITORING REPORT 3
3.1 WATER SUPPLY WELLS
During November 2010, Mountain Environmental personnel performed a water supply well survey and sensitive receptor update within a 1,000-foot radius of the site by mailing well survey forms to all property owners within a 500-foot radius of the site, visually observing surrounding properties for wells and water
meter connections and interviewing local residents. Based on the visual receptor survey and returned water supply well information sheet(s), no active water supply wells were identified within 1,000 feet of the source area. One (1) abandoned public water supply well owned by the Town of Black Mountain is located approximately 900-feet northwest of the source area. 3.2 PUBLIC WATER SUPPLIES Municipal water is available to the site and surrounding community by the Town of Black Mountain. 3.3 SURFACE WATER CES reviewed a USGS 7.5-minute quadrangle topographic map (Figure 1) to identify potential surface water bodies in the vicinity of the site. Site reconnaissance and topographic map review identified one (1)
surface water body within 1,500-feet of the site. The nearest surface water body is the Swannanoa River located approximately 420-feet south of the source area. 3.4 WELLHEAD PROTECTION AREA According to the NCDEQ Division of Water Resources Source Water Assessment Program (DWR SWAP) website, the source area is reportedly not located within an approved wellhead protection area.
3.5 DEEP AQUIFERS IN THE COASTAL PLAIN PHYSIOGRAPHIC PROVINCE The risk classification criteria specified in Title 15A of the NCAC, Subchapter 2L, Section .01159(d) requires an evaluation for the presence of unconfined or semi-confined deep aquifers in the Coastal Plain region of North Carolina, which may be used as a source of drinking water. According to the September 29, 2015 “Physiographic Provinces of NC” map, the site is not located within the Coastal Plain Physiographic Province. 3.6 SUBSURFACE STRUCTURES Subsurface water, sewer, and natural gas lines are present in the subsurface at the site. 3.7 PROPERTY OWNERS AND OCCUPANTS The site currently contains an active commercial convenience store with retail petroleum sales. Nine (9) contiguous properties are abutting the site as summarized in Table 4 and labeled on Figure 3. The site and
abutting properties are utilized for commercial purposes. 3.8 SENSITIVE LAND USE FEATURES
Sensitive land use features are defined by the NCDEQ as schools, daycare centers, nursing homes, hospitals, playgrounds, parks and recreation areas, churches, camps, and other places of public assembly. Based on the available information, the nearest specific sensitive land use feature is the trailhead for the River Walk
Park located approximately 920-feet east of the site. A public splash park is located approximately 1,350 feet north of the site. The Black Mountain Public Library and the Harwood Home for Funeral and Cremation Services are located approximately 1,000 feet northwest of the site while the Grace and Knowledge Community Church is located approximately 775 feet southwest of the site. 3.9 SURROUNDING LAND USE The subject site is a commercial service station and convenience store and is located in an area of Black Mountain that is commercially developed with retail shopping and dining facilities and some surrounding residential areas.

4.0 RECENT ACTIVITIES
CES has performed a limited groundwater monitoring event in accordance with the NCDEQ approved
pre-approval task authorization (PATA) 28783-24. A copy of the approved PATA form is included in Appendix A.
4.1 GROUNDWATER SAMPLING CES mobilized to the site on November 3, 2023, to conduct a groundwater monitoring event. Monitoring wells MW-1RA and MW-2 through MW-5 were located, accessed, and gauged for
equilibrated depth to water/depth to product (as applicable) and total well depth using an electronic oil-water interface probe. A summary of well construction and recent gauging data is included in Table 5. Following gauging, each monitoring well was purged of at least three (3) well volumes, or until dry, using dedicated disposable bailers. The bailer was gently lowered into the water column of the well and allowed to fill, then raised to the surface and evacuated. This process was repeated until the necessary volume of water had been removed from the well. To reduce the potential of cross contamination, new, clean, disposable nitrile gloves were worn during all phases of sample handing. Samples were placed into laboratory supplied containers pre-filled with appropriate preservatives, labeled with indelible ink, entered onto a chain-of-custody form, and immediately placed on wet ice in laboratory
supplied coolers maintained at approximately four (4) degrees Celsius pending transportation. The samples were transported under standard chain-of-custody protocol to Pace Analytical Services located in Huntersville, North Carolina, a North Carolina certified laboratory, for chemical analysis. The samples were analyzed for volatile organic compounds (VOCs) including MTBE, IPE, and EDB by Standard Method 6200B.
4.2 GROUNDWATER OCCURRENCE AND FLOW DIRECTION Depth to groundwater in the gauged monitoring wells ranged from 3.95-feet below top of casing (MW-5) to 7.33-feet below top of casing (MW-2). Groundwater elevations were calculated to range from 91.66-feet
(MW-2) to 90.19-feet (MW-5) relative to a common benchmark with an assumed elevation of 100.00 feet. A summary of groundwater gauging data is provided in Table 5. Based on this data, groundwater flow direction was generally interpreted to be overall towards the south as illustrated on Figure 5. The groundwater flow direction is generally consistent with historical assessments. The hydraulic gradient (i) was derived based on the referenced potentiometric map. The gradient was calculated based on the change in head over the horizontal distance between monitoring wells. For the purposes of the gradient calculations, MW-1RA was utilized as the up-gradient location and MW-5 is
utilized as the down-gradient location. Change in head (h): 91.30 (MW-1RA) to 90.19 (MW-5) = 1.11-feet
Horizontal distance (L): 86.396-feet i = h/L = (1.11-feet/86.396-feet) = 0.0128
4.3 LABORATORY RESULTS Laboratory analytical results were compared to the 2L Standards and GCLs. Upon review of the laboratory analytical report, the groundwater samples from monitoring wells MW-1R, MW-3, MW-4 and MW-5 contained concentrations of dissolved phase COCs at levels above 2L Standards.

ROADRUNNER #135: GROUNDWATER MONITORING REPORT 5
A summary of laboratory results for groundwater samples is provided in Table 6. Isoconcentration maps
for BTEX and MTBE are provided in Figure 6A through Figure 6E. The laboratory analytical report and chain of custody documentation are provided in Appendix B.
A trend graph comparing the groundwater elevation to the benzene concentration in monitoring well MW-1/MW-1R/MW-1RA has been included as Appendix C.
4.4 ESTIMATED EXTENT OF CONTAMINATION Soil Soil sampling was conducted at the site on June 28, 2023, when soil samples were collected from nine (9) soil borings. Based on the June 2023 soil sampling, the extent of soil contamination above MSCCs is generally located in the vicinity of the pump islands and east of the UST basin, totaling approximately
13,200 square feet. (Figure 4). Based on historical soil analytical data, the extent of the soil contamination above MSCCs is generally located to the east of the pump islands and south and east of the UST basin. The depth of the soil contamination extends to at least 7-feet bgs, after which point an apparent smear zone is encountered. This equated to a volume of 78,400 cubic feet. Maximum detected concentrations (MDCs) of contaminants of
concern (COCs) and the applicable cleanup goals for soil are summarized below in Exhibit 1: Exhibit 1 – Maximum Detected Concentrations for Soil Compared to Cleanup Goals
COC STW MSCC
Red = above STW MSCC Highlighted = above Ind/Comm MSCC Free Product Free product was not detected during the November 2023 sampling event. Historically, free product has been detected in monitoring well MW-5 at a maximum thickness of 0.60-feet in September 2015 with the last occurrence being in March 2016.
Groundwater Historically, groundwater contamination above 2L Standards has been reported at the locations of MW-1, MW-3, MW-4, MW-5, and MW-6. According to current data, the total extent of groundwater contamination above 2L Standards comprises an approximate 16,780-square foot area beneath the site and likely includes portions of the currently active UST system. The vertical extent of groundwater contamination is unknown.
GROUNDWATER MONITORING REPORT ROADRUNNER #135 BLACK MOUNTAIN, NORTH CAROLINA INCIDENT #28783
ROADRUNNER #135: GROUNDWATER MONITORING REPORT 6
The contaminant plume appears to be oriented primarily in a north-south direction with the monitoring well
exhibiting the highest contaminant concentrations being MW-1RA.
During the most recent monitoring event, COCs in groundwater exceeded the 2L Standards at four (4) of
the five (5) locations monitored. The current maximum groundwater contaminant concentrations above regulatory standards observed during the recent reporting period compared to the historical maximum groundwater contaminant concentrations observed are summarized in Exhibit 2 below:

Data presented in micrograms per liter (ug/L) Bold = Above 2L Standards Red = Above GCLs A cross section location map is included as Figure 7. Cross sections indicating the current extent of
contamination above regulatory limits and the assumed smear zone thickness based on historical water table elevations are included as Figures 8A and 8B. Estimated horizontal extents of dissolved BTEX and MTBE, are included as Figure 6A through Figure 6E, respectively.
4.5 EVALUATION OF CONTAMINANT MASS Contaminant mass was based on total BTEX. To determine contaminant mass, the average of total BTEX
concentrations from all monitoring well samples containing concentrations above 2L Standards and/or GCLs (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 area as shown on Figures 6A through 6D. 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 porosity (0.35) 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 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 mass may vary across different portions of the site. However, this method is considered effective for evaluation of trend data,
expansion/contraction of the plume, and overall site remediation progress. The current estimated mass of BTEX in groundwater was calculated to be approximately 40.1 lbs. or 18.2
kgs.

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:
• Laboratory results from the groundwater monitoring event reported exceedances of 2L Standards in the samples collected from monitoring wells MW-1R, MW-3, MW-4, and MW-5. However, no exceedances to the applicable GCLs were observed during the November 2023 monitoring event.
• An evaluation of contaminant mass revealed the current estimated mass is 40.1-lbs.
• The presence of a surface body of water within 1,000-feet of the site and the occasional presence of benzene above GCLs contribute to the site’s risk ranking.
5.2 RECOMMENDATIONS CES recommends the following:
• Complete requested NCDEQ soil excavation activities to address the soil contamination above the Industrial/Commercial Cleanup Levels.
• Perform semi-annual groundwater sampling for an additional year to monitor seasonal fluctuations and distribution trends.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
