Reference: Initial Abatement Action Addendum Report for the Betsy Chapman Property
1403 Wehunt Store Road, Cherryville, Lincoln County; Incident Number: Pending

Cedar Rock Project Number: 364622590

Dear Mr. Taraban:

Please accept this Initial Abatement Action Addendum Report for a release of fuel oil and gasoline from
two non-commercial underground storage tanks (USTs) formerly located at the above referenced property.
This report satisfies the requirements specified in the Underground Storage Tank Section Guidelines for
Site Checks, Tank Closure, and Initial Response and Abatement, Change 11 (May 17, 2021). Two USTs,
one used for storing home heating oil and one used for storing gasoline, were removed from the subject
property on May 23, 2023. A total of 105.08 tons of impacted soil were excavated from beneath the USTs
and transported to a permitted facility for bioremediation as an initial abatement measure. The laboratory
results for five soil samples collected from the limits of each excavation showed that petroleum residuals
exceeding applicable standards remain in the unexcavated soils beneath both USTs.

On June 15, 2023, a further 60.44 tons of contaminated soils were excavated from beneath the former
location of UST T1. The laboratory results for four soil samples collected from the limits of this excavation
showed that no petroleum residuals exceeding applicable standards remain in the unexcavated soils beneath
the former location of UST T1. Cedar Rock recommends that no further soil or groundwater assessment
and remediation activities should be required. The existing water supply wells on the subject property
should be properly abandoned and a new water supply well installed at a distance greater than 150 feet from
the release area of UST T2. Cedar Rock would then recommend that a Notice of Residual Petroleum (NRP)
be filed with the Lincoln County Register of Deeds office and that the DEQ should issue a conditional
Notice of No Further Action (NFA) letter to the property owner. Public notice should then be made to the
adjacent property owners and appropriate public authorities. Upon receipt of proof that the public notice
requirements have been completed, and that the NRP has been filed, the DEQ should then reissue the NFA
letter with no conditions to officially close out the petroleum release incident. If you have any questions or
need additional information, please give me a call.

Sincerely,

Robert A. Payne, L.G.

1.0 SITE HISTORY AND CHARACTERIZATION

The project site is a residential property located at 1403 Wehunt Store Road in Cherryville, North
Carolina (see Figure 1). Two 510-gallon underground storage tanks (USTs), identified as T1 and
T2 respectively, were located as shown in Figure 2. UST T1 was used for storing gasoline, and
UST T2 was used for storing home heating oil. Two aboveground storage tanks, identified as T3
and T4, used for storing home heating oil and diesel, respectively, were also located as shown in
Figure 2. City water is not available to properties in the area. The locations of the onsite water
supply wells are shown in Figure 3.

Underground tank removal activities were performed on May 23, 2023, under the supervision of
Cedar Rock Environmental (Cedar Rock). The two ASTs were also removed by Cedar Rock on
the same date. Initial abatement activities consisted of excavating a total of 105.08 tons of
obviously contaminated soil from the source areas of the releases. As detailed in the Initial
Abatement Action Report, laboratory analyses of soil samples collected from the limits of each
excavation showed that soil contamination exceeding the applicable TPH Action limits remained
in the unexcavated soils beneath both USTs.

2.0 EXCAVATION OF CONTAMINATED SOIL

2.1 Field Activities

On June 15, 2023, additional soil excavation activities in the source area of the release from
UST T1 were performed under the supervision of Cedar Rock (see photographs in Appendix
A). As impacted soil was removed from the source areas, the soil was periodically inspected
by a North Carolina licensed geologist for evidence of petroleum residuals (staining and
odors). Soil removal continued to a maximum depth of 23.0 feet below land surface (bls). The
lateral dimensions of the excavation pit measured about 11.0 feet by 6.5 feet at the pit floor
(see Figure 3). Neither bedrock nor groundwater were encountered during excavation
activities. A total of 60.44 tons of contaminated soil were transported to a permitted disposal
facility located in Lattimore, North Carolina for bioremediation. Copies of the soil disposal
manifests are included in Appendix B.

2.2 Soils Investigation

According to the Geologic Map of North Carolina (1985), the subject site is underlain by
biotite gneiss and schist. The native soils in the source area of the release consisted of a maroon
micaceous sandy SILT. A copy of the excavation log for the June 15, 2023, excavation is
included in Appendix C.

On June 15, 2023, Cedar Rock collected four soil samples, CR-7A through CR-10A, from the
limits of the excavation to document the effectiveness of the second soil excavation. Sample
locations are shown in Figure 3. The soil samples were collected according to the sampling
procedures included in Appendix D.

2

Soil samples CR-7A through CR-10A were submitted to the laboratory to be analyzed for
Gasoline Range Organics (GRO) by EPA Method 8015C and lead by EPA Method 6010. GRO
were quantified at concentrations of 10.9 parts per million (ppm) in sample CR-7A, 20.9 ppm
in sample CR-8A, and 35.0 ppm in sample CR-10A. No GRO were detected in sample CR-
9A. Lead was detected at concentrations of 41.3 ppm in sample CR-7A, 19.6 ppm in CR-8A,
6.8 ppm in CR-9A, and 8.6 ppm in CR-10A. No GRO concentration exceeded the applicable
action limit for total petroleum hydrocarbons and no lead concentration exceeded the soil-to-
groundwater MSCC. Soil sampling activities and results are summarized in Table 1. A copy
of the laboratory report and chain-of-custody is included in Appendix E.

2.3 Discussion of Results

Figure 3 shows a plan view of the source area, limits of the excavations, and soil sample
locations in relation to the former locations of the USTs. Soil removal continued to a maximum
depth of 23.0 feet in the source area of the release from UST T1. The lateral dimensions of
the excavation at the pit floor measured about 11.0 feet by 6.5 feet. Four soil samples were
collected from the limits of the excavation where contamination was most likely to remain. As
shown in Table 3, no petroleum constituents exceeding applicable standards were quantified
in the soil samples.

3.0 CONCLUSIONS AND RECOMMENDATIONS

Two USTs, one used for storing home heating oil and one used for storing gasoline, were removed
from the subject property on May 23, 2023. A total of 105.08 tons of impacted soil were excavated
from beneath each UST and transported to a permitted facility for bioremediation as an initial
abatement measure. The laboratory results for five soil samples collected from the limits of each
excavation showed that petroleum residuals exceeding applicable standards remain in the
unexcavated soils beneath both USTs.

On June 15, 2023, an additional 60.44 tons of contaminated soils were excavated from beneath the
former location of UST T1. The laboratory results for four soil samples collected from the limits
of this excavation showed that no petroleum residuals exceeding applicable standards remain in
the unexcavated soils beneath the former location of UST T1. Cedar Rock recommends that no
further soil or groundwater assessment and remediation activities should be required. The existing
water supply wells on the subject property should be properly abandoned and a new water supply
well installed at a distance greater than 150 feet from the release area of UST T2. Cedar Rock
would then recommend that a Notice of Residual Petroleum (NRP) be filed with the Lincoln
County Register of Deeds office and that the DEQ should issue a conditional Notice of No Further
Action (NFA) letter to the property owner. Public notice should then be made to the adjacent
property owners and appropriate public authorities. Upon receipt of proof that the public notice
requirements have been completed, and that the NRP has been filed, the DEQ should then reissue
the NFA letter with no conditions to officially close out the petroleum release incident.

Sampling & Decontamination Procedures

CEDAR ROCK ENVIRONMENTAL, P.C.
EQUIPMENT DECONTAMINATION PROCEDURES

Every effort will be made to prevent cross-contamination of soil and groundwater samples before,
during, and after sample collection. It is company policy that drillers contracted by Cedar Rock decontaminate their drilling and sampling equipment with steam prior to, and after, each use and/or
each boring. The following procedures apply to the decontamination of field equipment used by
Cedar Rock employees.

Soil Sampling Equipment
Stainless steel hand augers, spoons, and knives will be cleaned prior to, and after, each use and/or
each boring. If hand auger advancement of a borehole through contaminated soil is obvious or suspected, a clean auger bucket will be used to retrieve the sample portion. A fresh pair of
disposable vinyl gloves will be worn while handling the sample container.
Sampling equipment will be decontaminated by washing with phosphate-free soapy water; rinsing
in tap water followed by an isopropyl alcohol rinse; and a final “triple” rinse with distilled water.
The equipment will then be allowed to air dry. Clean sampling spoons and knives will be stored in a fresh ziplock bag.
If available, steam may be used instead of the above procedure.

Groundwater Sampling Equipment
Use of groundwater level measuring devices will proceed from the wells known to be the least
contaminated to those known to be more contaminated. If it is not known how contaminated the wells are, measurements will be taken on the up gradient wells prior to the down gradient wells.
A fresh pair of disposable vinyl gloves will be worn at each well during water level and sample
collection.
Water level measuring and well sampling (i.e., pumps and lines) devices will be decontaminated between wells by washing the wetted portion of the device as described above.

Each well will be sampled with a new disposable or decontaminated, dedicated bailer during each sampling event. New nylon or cotton string will be used during each sampling event on each
bailer. If the bailer contains a significant quantity of silt or sand after purging the well of stagnant
water, the bailer may be flushed with distilled water. The bailer will never come into contact with anything other than a gloved hand or the inside of the well casing. While allowing the well to
recover, the bailer will be hung inside the well at the top of the casing. The string will be coiled and placed in a ziplock bag or vinyl glove such that it does not come into contact with other objects.

Groundwater sample containers will be wiped dry and stored in individual ziplock bags.

CEDAR ROCK ENVIRONMENTAL, P.C.
SOIL SAMPLING PROCEDURES (Collection and Handling)

Soil sampling will be performed by, or under, the direct supervision of a North Carolina licensed geologist. Care will be taken to minimize the loss of contaminants from the sample during sample
collection, storage, and transport through disturbance of the internal structure of the soil and
exposure to heat, sunlight, and air. Decontamination and handling procedures will be used that minimize the chance of cross-contamination of the samples during and after sample collection.

All tools used to retrieve, divide, and collect the sample portion (e.g., hand augers, split-barrel
sampler, stainless steel spoons, etc.) will be decontaminated prior to and after each use (between
samples). See Decontamination Procedures.
Vinyl disposable gloves will be worn during sample collection. Gloves will be changed as
necessary after handling the sampling equipment (i.e., after breaking open split-barrels) to avoid cross-contamination. Contact between the gloved hand and the soil will be minimized by dividing
and collecting the sample portion using a stainless steel spoon or knife.
The sample portion will be collected from the core of the soil at the end of the sampling device
where the deepest retrieved soil is represented (e.g., hand auger teeth). If the sample is being
retrieved using the backhoe bucket, the sample portion will be collected from the consolidated material located directly behind one of the bucket teeth. A separate sampling implement will be
used to scrape away foreign material if present and/or the soil which came into contact with the sample retrieving device in order to expose the core of the sample portion to be collected.

Immediately upon removal from the ground, the sample will be placed in a laboratory-provided, decontaminated container. The sample container will be precooled, if possible, to minimize loss
of volatiles. The sample portion will be disturbed as little as possible during placement into the
container. The container will be filled leaving no head-space and immediately capped and sealed.
Immediately upon collection, the exterior of the sample container will be wiped free of soil, if
necessary, and placed in a ziplock bag to minimize cross-contamination. The sample will immediately be placed in a cooler of ice for storage and transport to the analytical laboratory.
The sample will be labeled with sample identification number, project number, date and time of
collection, and analyses to be conducted. The sample will be transported as soon as practical to a
North Carolina certified laboratory under chain-of-custody.

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.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
