1.0 SITE HISTORY AND CHARACTERIZATION

The project site is a residential property located at 2376 Baker Crossroad in Reidsville, North
Carolina (see Figure 1). A single above ground storage tank (AST) of unknown size and
capacity was previously removed from the subject property. According to the Rockingham
County Tax Office records, the house was built in 1970. Table 1 lists pertinent storage tank
system ownership information. Table 2 lists specific AST information for T1.

The subject site is surrounded by single-family, rural residential homes. Municipal water is not
available to the surrounding properties. The location of the onsite water supply well is shown in
Figure 2.

2.0 INITIAL RESPONSE AND ABATEMENT ACTIVITIES

On November 18, 2019, Cedar Rock Environmental, P.C. (Cedar Rock) performed an initial
inspection of the subject property. An oil-stained area was observed in the crawlspace of the
residence near the former location of the furnace. Laboratory analysis of a soil sample, CR-1,
collected on November 18, 2019, at a depth of three feet within the stained area confirmed that
the AST heating system had leaked causing significant contamination of the soils beneath the
residence. On November 25, 2019, Cedar Rock collected two further samples, CR-2 and CR-3,
to help determine the extent of the release.

On January 6, 2020, Cedar Rock excavated 6.40 tons of obviously contaminated soil from the
source area of the release. Soil removal continued to a maximum depth of 5.5 feet. The lateral
dimensions of the excavation pit measured about 12.5 by 5.5 feet at the pit floor. The excavated
contaminated soil was transported by Zebra Environmental & Industrial Services Inc. of High
Point, North Carolina, to a permitted disposal facility located in Sanford, North Carolina for
bioremediation. The excavation pit was subsequently backfilled with a flowable fill cement
slurry on January 24, 2020.

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 Reporting Form (UST-62) was submitted to the North
Carolina Department of Environmental Quality (DEQ), Division of Waste Management (DWM),
UST Section in Winston-Salem on January 13, 2020.

3.0 EXCAVATION OF CONTAMINATED SOIL

3.1 Field Activities

Soil excavation activities were performed on January 6, 2020 (see photographs in Appendix
A). As impacted soil was removed from the source area, the soils were periodically
2

inspected by a North Carolina licensed geologist for evidence of petroleum residuals
(staining and odors). Soil removal continued until a depth of 5.5 feet. The lateral
dimensions of the excavation pit measured about 12.5 by 5.5 feet at the pit floor (see Figure
3). Neither bedrock nor groundwater were encountered during excavation activities. A total
of 6.40 tons of contaminated soil were transported to a permitted disposal facility located in
Sanford, North Carolina for bioremediation. A copy of the soil disposal manifest is included
in Appendix B.

The excavation pit was backfilled to grade on January 24, 2020 using a flowable fill cement
slurry. As an added measure, the excavation pit was lined with six mil plastic sheeting to act
as a vapor barrier prior to backfilling.

3.2 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 an
orange-brown, micaceous, sandy SILT. A copy of the excavation log is included in
Appendix C.

Soil sample CR-1, collected on November 18, 2019, and samples CR-2 and CR-3, collected
on November 25, 2019 for defining the approximate extent of the contamination. The
samples were submitted to the laboratory to be analyzed for total petroleum hydrocarbons
(TPH) by EPA Method 3550. TPH were quantified by Method 3550 at concentrations of
11,100 parts per million (ppm) in CR-1, 43.7 ppm in CR-2, and 54.6 ppm in CR-3.

Five soil samples, CR-4 through CR-8, were collected by Cedar Rock on January 6, 2020 to
document the effectiveness of the soil excavation. The soil samples were collected from the
limits of the excavation as shown in Figure 3. All soil samples were collected according to
the sampling procedures included in Appendix D. Soil samples CR-4 through CR-8 were
submitted to the laboratory to be analyzed for total petroleum hydrocarbons (TPH) by EPA
Method 3550 and EPA Method 5030. No TPH were detected by either method in samples
CR-4 through CR-8. Soil sampling activities are summarized in Table 3. A copy of the
laboratory reports and chains-of-custody for the soil samples are 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. Soil removal continued to a depth of 5.5 feet. The lateral dimensions of the
excavation pit measured about 12.5 by 5.5 feet at the pit floor.

Five soil samples were collected from the limits of the excavation where contamination was
most likely to remain. As shown in Table 3, no petroleum hydrocarbons were quantified in
these soil samples.

4.0 CONCLUSIONS AND RECOMMENDATIONS

A single AST, used for storing home heating oil, was previously removed from the subject
property on an unknown date. On January 6, 2020, a total of 6.40 tons of impacted soil were
3

excavated from beneath the residence and transported to a permitted facility for bioremediation
as an initial abatement measure. Laboratory analysis of soil samples collected from the limits of
the excavation indicate that no petroleum contamination remains in the unexcavated soils. The
excavation pit was backfilled to grade with a flowable fill cement slurry on January 24, 2020.

Cedar Rock recommends that the DWM should issue a Notice of No Further Action letter to the
property owner to close out the release incident.

Sampling & Decontamination Procedures

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.

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.
