Dear Ms. Moyle:

Please accept this Initial Assessment and Abatement Action Report for a release of fuel oil from one non-
commercial aboveground storage tank (AST) 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).

One AST, used for storing home heating oil, was previously removed from the subject property
on January 12, 2022. On January 27, 2022, a total of 29.03 tons of impacted soil were excavated
and transported to a permitted facility for bioremediation as an initial abatement measure. The
laboratory results for seven soil samples collected from the limits of the excavation showed that
petroleum residuals exceeding applicable standards remain in the unexcavated soils. Cedar Rock
recommends further excavation of contaminated soils in an attempt to remove all remaining soil
contamination from the release area.

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 1958 Penland Road in Spruce Pine, North
Carolina (see Figure 1). One 275-gallon aboveground storage tank (AST), identified as T1, was
located as shown in Figure 2. According to the Mitchell County tax office records, the building
was constructed in 1949. Table 1 lists pertinent storage tank system ownership information. Table
2 lists specific AST information for T1. The subject site is surrounded by rural residential
properties and undeveloped woodland. City water is not available to properties in the area. The
subject property is supplied with water from an onsite water supply well. The location of this well
is shown in Figure 2.

2.0 INITIAL ASSESSMENT AND ABATEMENT ACTIVITIES

The AST was previously removed by Cedar Rock Environmental (Cedar Rock) on January 12,
2022. An area of soils stained by leaked heating oil was observed to extend approximately 30 feet
down gradient to the southwest of the AST location.

On January 27, 2022, Cedar Rock supervised initial abatement activities which consisted of the
excavation of 29.03 tons of obviously contaminated soil from the source area of the release. Soil
removal continued to a maximum depth of 7.0 feet. The overall lateral dimensions of the
excavation pit measured about 36.0 feet by 7.5 feet. The excavated contaminated soil was
transported to a permitted disposal facility located in Sanford, North Carolina for bioremediation.

No free product was encountered during the initial abatement activities. There are no other
subsurface structures on the subject site where free product or vapors could accumulate, or that
would provide a migration pathway for the release. The possibility of an explosion or the threat
to public health and safety or to the environment from the accumulation of vapors does not appear
to be of concern at this time. Therefore, the release is unlikely to be a significant fire/safety/health
hazard.

The 24-Hour Notification of Discharge Form (UST-62) was submitted to the North Carolina
Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), UST
Section in Swannanoa on January 20, 2022.

3.0 EXCAVATION OF CONTAMINATED SOIL

3.1 Field Activities

Initial abatement activities were performed on January 27, 2022 (see photographs in Appendix
A). Petroleum-impacted soils were encountered at land surface in the source area. As
impacted soil was removed from the source area, the soils were periodically inspected by a
North Carolina licensed geologist for evidence of petroleum residuals (staining and odors).
Soil removal continued to a maximum depth of 7.0 feet. The lateral dimensions of the
excavation pit measured about 36.0 feet by 7.5 feet at the pit floor (see Figure 3). Neither
bedrock nor groundwater were encountered during excavation activities.

2

A total of 29.03 tons of contaminated soil were transported to a permitted disposal facility
located in Sanford, North Carolina for bioremediation. Copies of the soil disposal manifests
are included in Appendix B.

3.2 Soils Investigation

According to the Geologic Map of North Carolina (1985), the subject site is underlain by
muscovite-biotite gneiss. The native soils in the source area of the release consisted of a
brownish orange sandy SILT. A copy of the excavation log for the excavation is included in
Appendix C.

On January 27, 2022, Cedar Rock collected seven soil samples to document the effectiveness
of soil excavation. Soil samples CR-1 through CR-7 were collected from the limits of the
excavation. Sample locations are shown in Figure 3. The soil samples were collected
according to the sampling procedures included in Appendix D.

Soil samples CR-1 through CR-7 were submitted to the laboratory to be analyzed for Total
Petroleum Hydrocarbons (TPH) by EPA Methods 3550 and 5030. TPH were quantified by
EPA Method 3550 at concentrations of 2,150 parts per million (ppm) in sample CR-1, 213
ppm in sample CR-3, 18,800 ppm in sample CR-4, 16,600 ppm in sample CR-5, and 567
ppm in sample CR-6. TPH were quantified by EPA Method 5030 at concentrations of 63.4
ppm in sample CR-1, 928 ppm in sample CR-4, and 628 ppm in sample CR-5. No TPH were
quantified in soil sample CR-2 either of the methods, and no TPH were quantified in soil
samples CR-3, CR-6 and CR-7 by Method 5030. Results presented in bold exceeded the
applicable TPH Action Limits. Soil sampling activities and results are summarized in Table
3. A copy of the laboratory report and chain-of-custody is included in Appendix E.

3.3 Discussion of Results

Figure 3 shows a plan view of the source area, limits of the excavation, and soil sample
locations in relation to the former location of the AST.

Petroleum-impacted soils were encountered in the source area at land surface. Soil removal
continued to a maximum depth of 7.0 feet. The lateral dimensions of the excavation pit
measured about 36.0 feet by 7.5 feet at the pit floor.

Seven soil samples were collected from the limits of the excavation where contamination was
most likely to remain. As shown in Table 3, petroleum constituents exceeding applicable
standards were quantified in these soil samples.

4.0 CONCLUSIONS AND RECOMMENDATIONS

One AST, used for storing home heating oil, was removed from the subject property on January
12, 2022. A total of 29.03 tons of impacted soil were excavated and transported to a permitted
facility for bioremediation as an initial abatement measure on January 27, 2022. The laboratory

results for seven soil samples collected from the limits of the excavation showed that petroleum
residuals exceeding applicable standards remain in the unexcavated soils. Cedar Rock
recommends further excavation of contaminated soils in an attempt to remove all remaining soil
contamination from the release area.

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.
