Site History and Background

The Site is currently a vacant building structure, formerly a fuel service station, consisting of Burke
County Parcel ID 2659-06-7323. The parcel consists of approximately 1.07 acres of land. The Site
and surrounding properties are zoned Residential Mixed Use (R-MU). The former UST system
included one (1) 7,000-gallon gasoline Underground Storage Tank (UST) basin and a separate
basin containing two (2) 1,000-gallon gasoline and one (1) 550-gallon kerosene USTs as illustrated
on Figure 2. The three smaller USTs were installed in 1966 and the 7,000-gallon UST was installed
in 1979. The location of the former UST system is illustrated on Figure 2. Please refer to Table 2 -
UST/AST Owner/Operator and Other Responsible Party Information for additional information.

Asphalt and gravel with lawn areas transitioning into woodland are the primary surface covers at
the Site. Residential properties, agriculture and woodland predominantly surround the immediate
Site vicinity. Adjacent property owner information is summarized on Table 3 - Adjacent Property
Owners and depicted on Figure 3.

The Site elevation appears to range from approximately 1,238 feet above Mean Sea Level (MSL)
along the northwestern portion of the Site to approximately 1,252 feet above MSL along the southern
property boundary. The Site generally resides on a northeastern sloping hillside towards
Abee/Queens Creek. Municipal water is available and is utilized at the Site as the primary source
of potable water. Based on natural and surface topography the primary groundwater flow appears
to be towards the north/northwest. The nearest surface water body is a spring fed tributary located
150 feet south and Abee/Queens Creek located approximately 230 feet north of the Site source
area. Water Supply Wells (WSWs) are also present at the Site and surrounding properties. Please
refer to Table 4 for additional information.

During the UST system closure conducted on October 28, 2010 by ARM Environmental Services
(ARM), a release was discovered (Incident No. 28894) and was likely caused by leaking or overspills
related to the gasoline/kerosene UST System with an unknown quantity of product released.
Analysis of the UST closure soil samples revealed detectable contaminant concentrations of Total
Petroleum Hydrocarbons – Gasoline Range Organics (TPH-GRO) and TPH-Diesel Range Organics
(DRO) above the North Carolina Action Levels (AL) of 50 mg/kg and/or 100 mg/kg, respectively.

A Phase I Limited Site Assessment (LSA) was completed at the Site by ARM on June 7, 2011 and
included the installation and sampling of one type II two-inch shallow groundwater monitoring well
(MW-1). The monitoring well construction information and water level data are summarized on
Table 5 – Monitoring Well Construction Information. The laboratory analysis of the soil and
groundwater samples collected from MW-1 on June 7, 2011 revealed several contaminant
concentrations exceeding the North Carolina Soil to Groundwater maximum Contaminant
Concentrations (MSCCs) and Administrative Code (NCAC) 2L Groundwater Quality Standards (2L
Standards), respectively. A Phase II LSA was recommended as the next scope of work by ARM,
however, the Site has been inactive since 2011.

Notice of Regulatory Requirements (NORR) letters were subsequently issued and a Site visit was
conducted on September 14, 2017 by the NCDEQ for reevaluation of the current Site ranking (high)
Receptor Survey Update / Monitoring Report July 8, 2021
Former Country Quick Stop Page 5

to low risk due to specific hydrogeologic conditions (creeks) surrounding the Site and source area.
An updated receptor survey and groundwater monitoring event on MW-1 was conducted by Blue
Ridge on May 20, 2021 and is presented below.

Receptor Information

On May 20, 2021, Blue Ridge performed a receptor survey update consisting of a visual
reconnaissance to identify and confirm private and public WSWs, municipal water services and
wellhead protection areas located within 1,500 feet of the Site source area. In addition, a thorough
search of municipal, county or water district records/maps was conducted to locate possible
municipal utilities. Blue Ridge personnel attempted to identify unregistered or unmarked private
WSWs within 1,500 feet of the Site, including a visual reconnaissance of the surrounding area and
the solicitation of WSW questionnaires to property owners within 500 feet of the Site.

Furthermore, Blue Ridge personnel contacted Burke County Sewer and Water (BCSW) regarding
the availability of municipal water service in the Site vicinity and the presence of any known WSWs.
The receptor survey also included a search for surface water features within 1,500 feet of the Site,
subsurface structures (such as underground utilities or basements located on-site or on adjacent
properties) and areas of public assembly (such as schools, parks, and churches) within 1,500 feet
of the Site.

The properties identified surrounding the Site utilize a combination of the municipal water service
provided by BCSW or private WSWs. Active municipal water service accounts were verified by
telephone with BCSW and/or visually. The properties located on East & West Meadow Drive
associated with WSW-7 through WSW-10 and WSW-12 through WSW-18, did not have water
service accounts or water meters observed. Furthermore, a neighboring resident assisted with
verifying WSW usage during the Site reconnaissance.

The nearest surface water body is an unnamed spring fed tributary located 150 feet south and cross
gradient and Abee/Queens Creek located approximately 230 feet east and downgradient of the Site
source area. The unnamed tributary creates the western property boundary, while Abee/Queens
Creek creates the northern property boundary for the Site before converging in the northwestern
property corner as documented in Appendix A - Site Photographs.

A Risk Classification and Land Use Form is included as Appendix B. Based on the information
obtained and confirmed during this assessment the Site will likely be reclassified to “Low Risk” with
further pending evaluation.

Copies of the WSW Information Surveys received are attached as Appendix C - WSW Questionaries
and additional WSW questionnaires that Blue Ridge receives will be forwarded to NCDEQ ARO as
an amendment to this report. Please refer to Table 4 - Public and Private Water Supply Well and
Other Receptor Information and Figure 3 for the location of all potential receptors identified within a
1,500-foot radius of the Site.

Blue Ridge Project No. 21-6205.1

Summary of Groundwater Analytical Results

On May 20, 2021, Blue Ridge personnel gauged the groundwater level in MW-1 after allowing the
well to equilibrate utilizing a Heron water level meter. From the top of casing, the depth to the
groundwater was 9.25 feet below grade level (bgl). No free product was detected in the monitoring
well at this time. Further construction details are in Table 5 - Monitoring Well Construction
Information.

Prior to sampling MW-1, Blue Ridge personnel fully purged and allowed the monitoring well to
equilibrate. The groundwater samples were placed into appropriate sample containers and labeled
with the project name, time and date of collection, and analysis to be performed. The filled sample
containers were placed in a cooler containing ice and transported to Pace in Columbia, South
Carolina (North Carolina-certified laboratory). A chain-of-custody form was maintained with the
samples. The groundwater samples were submitted and analyzed for Volatile Organic Compounds
(VOCs) by EPA Method 8260, EPA Method 625, MADEP-EPH, MADEP VPH and EPA Method
504.1 for EDB.

All the target constituents were analyzed at low level detection limits and several “estimated” results,
“J” values, and/or “B” Values were reported by the laboratory. The “J” values indicate a
concentration greater than the laboratory limit of quantitation and less than the detection limit. The
“B” Values are a concentration detected in the method blank. Details and reported “J” values and
“B” values can be found in the laboratory analytical data report included as Appendix E.

The laboratory analysis of the groundwater sample collected from MW-1 revealed contaminant
concentrations of Benzene (82 J ug/L), Toluene (2,700 ug/L), Ethylbenzene (2,000 ug/L), Xylenes
(12,000 ug/L), Naphthalene (540 ug/L), 1-Methylnaphthalene (60 ug/L), 2-Methylnaphthalene (540
ug/L), C9-C18 Aliphatics (8,800 ug/L), C11-C22 Aromatics (2,100 ug/L), C5-C8 Aliphatics (12,000
ug/L), C9-C12 Aliphatics (20,000 ug/L) and C9-C10 Aromatics (10,000 ug/L) above the NCAC 2L
Standard but not exceeding the Gross Contamination Levels (GCLs).

Groundwater laboratory analysis of MW-1 also revealed several detectable concentrations;
however, they were all below the NCAC 2L Standard. The remaining targeted aqueous analytes
revealed no detectable contaminant concentrations above the laboratory detection limits.

A copy of the May 20, 2021 groundwater laboratory analytical data & chain of custody records is
attached as Appendix E and the laboratory analytical results are summarized in Table 6 - Summary
of Groundwater Analytical Laboratory Results and on Figure 4 – Site Detail Map. A copy of Blue
Ridge’s Quality Assurance/Quality Control Procedures - Drilling and Field Activities Protocol is
included as Appendix F.

Conclusions

Based on the results of the receptor survey update and groundwater laboratory analytical results,
Blue Ridge offers the following conclusions:

Receptor Survey Update / Monitoring Report July 8, 2021

Connelly Springs, North Carolina 28612
Blue Ridge Project No. 21-6205.1

• The properties identified surrounding the Site utilize a combination of the municipal water
service provided by BCSW or private WSWs. Active municipal water service accounts were
verified by telephone with BCSW and/or visually. The properties located on East & West
Meadow Drive associated with WSW-7 through WSW-10 and WSW-12 through WSW-18, did
not have water service accounts or water meters observed. Furthermore, a neighboring
resident assisted with verifying WSW usage during the Site reconnaissance.

• The nearest surface water body is an unnamed spring fed tributary located 150 feet south and
cross gradient and Abee/Queens Creek located approximately 230 feet east and downgradient
of the Site source area. The unnamed tributary creates the western property boundary, while
Abee/Queens Creek creates the northern property boundary for the Site before converging in
the northwestern property corner.

• The laboratory analysis of the groundwater sample collected from MW-1 revealed contaminant
concentrations of Benzene (82 J ug/L), Toluene (2,700 ug/L), Ethylbenzene (2,000 ug/L),
Xylenes (12,000 ug/L), Naphthalene (540 ug/L), 1-Methylnaphthalene (60 ug/L), 2-
Methylnaphthalene (540 ug/L), C9-C18 Aliphatics (8,800 ug/L), C11-C22 Aromatics (2,100
ug/L), C5-C8 Aliphatics (12,000 ug/L), C9-C12 Aliphatics (20,000 ug/L) and C9-C10 Aromatics
(10,000 ug/L) above the NCAC 2L Standard but not exceeding the Gross Contamination Levels
(GCLs).

• Additional WSW questionnaires that Blue Ridge receives indicating a water supply well will be
forwarded to NCDEQ ARO as an amendment to this report.

• The Site source area is not located within a designated well head protection area.

Recommendations

Based on the information obtained and confirmed during this assessment, Blue Ridge recommends
the following regarding the on-site contamination:

 Submit a copy of this report to the NCDEQ ARO, Division of Waste Management, UST
Program for review and reclassification of initial risk classification. The Site will likely be
reclassified as a “Low Risk” ranking due to specific hydrogeologic conditions (creeks)
surrounding the Site and source area.

 Pending the “Low Risk” classification for the incident number, a Conditional Notice of No
Further Action (CNFA) is recommended.

 Furthermore, in accordance with the guidelines pertaining to a CNFA; a Public Notice and
Deed Recordation of soil and groundwater will be required prior to the incident number for
the Site receiving a Notice of No Further Action (NFA).

This Report of Analysis contains the analytical result(s)for the sample(s)listed on the Sample Summary
following this Case Narrative.The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt,sample analysis,and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI)standards,the Pace Analytical Services,LLC ("Pace")
Laboratory Quality Manual,standard operating procedures (SOPs),and Pace policies.Any exceptions to
the TNI standards,the Laboratory Quality Manual,SOPs or policies are qualified on the results page or
discussed below.
If you have any questions regarding this report please contact the Pace Project Manager listed on the
cover page.
Semivolatiles
The matrix spike/matrix spike duplicate (MS/MSD)associated with sample -001 had multiple compounds
recovered outside of the acceptance limits.The laboratory control sample (LCS)was recovered within the
required acceptance limits;therefore,this likely demonstrates a matrix effect.
Sample -001 was diluted due to high detections for target compounds.As a result,the associated
surrogates were recovered outside of the acceptance limits.No corrective action was required,as
dilutions of 5X and greater impact recovery accuracy.
EDB
The sample results associated with a P qualifier have a relative percent difference (RPD)between the two
dissimilar phase GC columns which exceeds 40%.

Blue Ridge Environmental Services, Inc.
Quality Assurance/Quality Control Procedures
Drilling and Field Activities Protocol

Pre-Drilling Protocol

Blue Ridge will contact a commercial utilities location service a minimum of 48 hours (per location service
requirements) prior to mobilization of the drill crew to the project site. It will be the responsibility of the utilities
location service to locate and delineate (by marking the ground surface), to the extent possible, buried or
underground utilities which may be encountered during or impeded by drilling activities. This should include but
may not be limited to electrical power services, private and/or municipal water and sewer services,
telecommunication services, natural gas services, and/or other public or municipal utilities. Borehole locations
will not be made closer than 36" from surface delineated utilities. If closer proximity to delineated utilities is
required, bore hole advancement will be conducted by hand auger boring protocol.

Prior to commencement of drilling, the augers, down hole equipment and associated tools will be cleaned in a
designated decontamination control area using a steam cleaner or high-pressure washer. Bulk soil material
which may remain inside or outside of the augers or tools will be removed. Augers will also be pressure
washed between each successive bore hole to remove any soil material from the preceding boring.

Before raising the drill rig mast, Blue Ridge drilling personnel will observe over-head conditions for the presence
of aerial mounted utilities, tree limbs, canopies, awnings, building overhangs or other structural impedances to
normal drill rig operations.

Drill Protocol and Techniques

Bore holes utilized in sub-surface intrusive investigations will be advanced using a trailer mounted Simco 2400
SK-1 drill rig equipped with 4.5 inch outside diameter solid stem augers or 3.25-inch hollow stem augers.

Where warranted, shallow boring hole advancement may require utilization of a steel hand auger equipped with
a 3" inside diameter barrel.

Soil Sampling Collection and Analysis

The sample preparation area at each bore hole location will be located as reasonably possible away from
running motors or where discharged vapors, exhaust and/or fumes may come in contact with the sample.
Towels, field meters, sample jars and other equipment will be placed such that they do not come into contact
with soil or other materials which may contaminate the sampled soils.

Unless specified by the client or by project requirements, soil samples will be collected at approximately 5-foot
intervals. Soil samples will be retrieved according to one of two sampling protocols (dependent upon project or
client requirements): (1) by split barrel sampling protocol or (2) from bulk soil material retrieved from the solid
stem auger following flight advancement.

In an effort to reduce cross contamination of samples, soil samples which are to be submitted for chemical
analysis will only be handled by the geologist using fresh, manufacturer clean, latex examination gloves.
Following retrieval, the soil sample from each interval will be split into roughly equal portions with one portion
subjected to field examination and classification by Blue Ridge geologic personnel and the remaining portion
placed into a glass sample container to await selection for chemical analysis.

Samples which are to be submitted for volatile constituent analysis will be thermally isolated by being placed
into the plastic ice chest. After the sample is retrieved from the bore hole and placed into the sample container,
the project name, sampling interval, data and time will be noted on the container.

Soil Screening and Photoionization Detector

Soil samples collected from each sampling interval will be subjected to on site screening by head space
analytical method utilizing a Photovac brand portable photoionization detector (PID). Prior to the soil screening,
the PID will be calibrated in the field to 98.9 parts per million (ppm) using isobutylene calibration gas per
manufacturer's standards.

Soil screening will be conducted by placing a spilt portion of each sample collected from the specified sampling
interval into a resealable plastic bag. The bag is then placed aside to allow the head space air above the
sample to equilibrate. Following the anticipated equilibration interval, the probe of the PID is inserted through
the side of the sample bag and the resulting levels of volatile organic vapors recorded. PID levels are recorded
in parts per million (ppm) and may be an indication of the relative concentration of volatile organic compounds
in the soil.

Monitoring Well Construction Protocol

Monitoring well bore hole advancement will be conducted utilizing 3.25 inch inside diameter hollow stem auger.
For typical monitoring well construction, the bore hole will be advanced through the vadose zone (over burden
soil) into the saturated zone to approximately 10 feet below the water table thereby allowing approximately 10
feet of hydrostatic head within the well. The boring will be converted into a groundwater monitoring well by the
emplacement of 2 inch inside diameter schedule 40 PVC pipe (well screen and riser). The well screen will have
a manufacturer machine cut 0.010 inch slot width and will be emplaced so the top of the well screen will be
located above the anticipated seasonal high water table. The annular space surrounding the well screen
will be backfilled utilizing an FX-2 filter sand (45 to 55 mm grain size) to approximately 2 feet above the top of
the well screen. The filter pack will be isolated by the emplacement of approximately 2 feet of bentonite pellets
and the bentonite seal will then be hydrated and allowed to seal. Following the bentonite seal hydration, the
remaining annular space will be backfilled to the surface grade utilizing a neat Portland Type II cement or

similar type grout. Typically, the wells will be completed at grade level inside a traffic rated steel vault and the
well sealed using a water-tight locking pressure cap. Where it is possible, the well vault will be raised above
the existing surface grade approximately 1 inch to promote surface water run-off and reduce the potential for
standing water above the well head.

Monitoring Well Development

Blue Ridge will allow an anticipated time interval for the well bore to stabilize following construction. The
monitoring well will then be developed by hand bailing utilizing a fresh manufacturer clean polyvinyl bailer. Well
development will be conducted until approximately 5 well volumes of water have been removed, the water is
relatively silt and sediment "free", or until essentially dry.

Well development should be performed to accomplish the following:

1) To remove silt and sediment which may have entered the well during construction activities.

2) To remove mud cake and "smeared material@ on the bore hole walls from drilling.

3) To seat and grade the filter pack.

4) To promote hydraulic conductivity into the well bore.

Monitoring Well Gauging

Static water levels within each monitoring well will be measured. Measurements will be made from the top of
the casing (riser) and recorded to the nearest 0.01 foot.

Blue Ridge will electronically measure for the presence of free product in suspect wells. Where free product is
indicated to be present, the depth to the top of the product layer and the depth to the top of the water will be
recorded. Measurement will be made from the top of the well casing (riser) and recorded to the nearest 0.01
foot. Monitoring wells will be gauged before performing sample collection events at other times that may be
required and warranted.

The water level indicator and the oil/water interface probe will be cleaned with a solution of laboratory grade
soap (Alconox) and distilled water, rinsed with distilled water, rinsed with methanol alcohol and finally rinsed
with deionized water both before the first well is checked and between successive wells. Bailers used to
inspect the water surface will also be cleaned between successive wells using a solution of 5% tri-sodium
phosphate and water.

Groundwater Sampling

Whenever possible, prior to conducting the initial sample collection event for any given monitoring well, Blue
Ridge will allow for the well to stabilize following monitoring well development. Before conducting each

sampling event, an attempt will be made to purge each well of a minimum of three volumes of water or until the
well becomes essentially dry. All wells will then be allowed to recharge in part or in whole prior to sampling.

Groundwater samples will be collected by Blue Ridge personnel utilizing disposable manufacturer clean
polyvinyl bailers equipped with a bottom ball check valve. An inert string will be used to lower the bailer to the
water surface. The string will be replaced between successive samples. The sample will be collected by gently
lowering the bailer into the water, thereby reducing degasification and/or volatilization of the sample. After the
bailer is lowered into the water, the sample will be allowed to stabilize for approximately three seconds, allowing
the ball valve to close. Care will be taken not to overfill the bailer, allowing inspection of the water surface upon
removal of the bailer from the well. Once the bailer is removed, water samples will be transferred to glass vials
in such a manner as to reduce volatilization. To reduce the potential of sample cross contamination, Blue
Ridge personnel will don fresh disposable latex examination gloves between each monitoring well sampling
point and whenever contact with groundwater is possible.

Transportation of Samples to Laboratory

Before drilling activities are initiated, a plastic ice chest will be prepared for temporary soil and water sample
storage. Preparation will include placing ice packs into the ice chest for thermal isolation in an attempt to
preserve sample integrity. The cooler will be pre-chilled using blue ice, ice packs or similar items to provide
thermal isolation of the sample materials.

The maximum holding time for samples to be tested for volatile organics is 14 days. Therefore, samples will be
delivered to the laboratory and analyzed by the laboratory within this time frame. The laboratory has been
consulted regarding holding times.

If the samples are taken directly to the lab from the drill site, they will be held in the same pre-chilled cooler. If
the samples cannot be taken directly to the lab, they will be taken to Blue Ridge's office, where the sample
containers will be transferred immediately from the cooler to the assigned refrigerator, until such time that they
can be taken to the lab. When the samples are scheduled to be delivered to the lab, they will be transferred
from the refrigerator to a pre-chilled cooler until delivery to the lab has been made.

Blue Ridge Chain of Custody Protocol

For each set of samples collected from the specified project site, Blue Ridge will enter all samples, containers,
and ice chests into standard chain of custody protocol. A chain of custody form will be established for each
sampling event a includes the following information: (1) project name and location, (2) sampling personnel, (3)
project management personnel, (4) sample identification numbers, (5) sample collection date and time, (6)
sample matrix {soil or water}, (7) sample description, (8) preservatives utilized, (9) number of containers, (10)
requested parameters, (11) miscellaneous field or laboratory remarks, (12) and transference records. The chain
of custody form will accompany the samples through each phase of the delivery process.
