Petroleum was observed in soil removed from sides and under
USTs
The recently closed petroleum USTs 1, 2 and 3 were located on the south side of the property (Figure 2).
The three USTs (1, 2 and 3) were previously used at the property by Tommy Turner as early as the 1950’s.
These were three 4,000 gallon petroleum (gasoline or diesel) USTs. A review of the UST database showed
that these USTs were never registered because they were taken out of service reportedly at some time in the
1970’s according to local informants. No release incident number has been associated with these tanks.
3. There are no known spills or releases from non-UST sources at the subject property prior to the release
discovered 10/11/16.
4. Provide a comprehensive description of the release, including date discovered, cause and source (including
tank identification number and contents), and the relationship of historical UST releases, non-UST
releases, and off-site releases (indicate incident number) to contamination from current release.
The USTs were permanently closed by removal between October 11 and October 13, 2016. During
removal of the tanks, it was noted that there were small holes in several spots on the tanks on the bottoms
and sides. Petroleum odors and staining were observed on the sides of the tanks and under the tanks.
Gasoline range organics and diesel range organics were detected under each tank. Diesel range organics
were found in all three samples under the middle tank (UST 2) and it is suspected that this was the diesel
storage tank.
Seramur & Associates is not aware of any non-UST releases or off-site releases that could be contributing
to contamination from current release.
4
5. Provide a brief description of site characteristics (including status of facility (active or inactive), land use
of site and surrounding area, water supply, topography, vegetation, surface water, wells, buildings, surface
cover, soil type, depth to and nature of bedrock, depth to groundwater, direction of groundwater flow, etc.)
The USTs were taken out of service reportedly at some time in the 1970’s according to local informants.
The property is currently used as a body shop/auto restoration facility. Surrounding land use is commercial
and residential. A public water supply is available to some properties in the area and a water supply well
was observed on at least one nearby property. Groundwater was not observed in the UST excavations.
The property is located between two ridges and adjacent to a valley that slopes to the east (Figure 1).
Miller’s Creek runs in a northwest to southeast direction in a valley east of the property. The creek is
approximately 1,000 feet from the UST excavation at its closest point. There is very little vegetation on the
property apart from grass near the highway and brush along the backside of the property. Roots were
observed in the tank pit, some as large as tree roots. The soil consists of sandy silt in the source area.
Bedrock was not encountered and depth to bedrock is unknown. Bedrock in this area is mapped as the
Ashe Formation, primarily a mica schist interbedded with a gneiss (Rankin, D.W., Espenshade, G.H., and
Neuman, R.B., 1972, Geologic Map of the West Half of the Winston-Salem Quadrangle, North Carolina,
Virginia, and Tennessee. Misc. Geol. Invest. Map I-709-A Dept. of the Interior, U.S. Geol. Surv.,
Washington D.C., 1 Map.).
6. Summarize initial abatement actions, assessment activities, and corrective actions performed to date and
list all reports previously submitted.
The USTs were permanently closed by removal between October 11 and October 13, 2016. Each trackhoe
bucket of soil removed from the two UST excavations was screened in the field for petroleum vapors with
a Photocheck 100 photoionization detector. Approximately 42 cubic yards of contaminated soil was
removed from around the USTs. Soil contamination appeared to be primarily limited to the area around
and under the tanks. Contaminated soil was transported to Environmental Soils, Inc. in Lattimore, NC.
Soil consisted of sandy silt to a depth of about 9 feet.
Three soil samples were collected from below each of the three USTs (Figure 4). Another composite
sample was collected from the two piles of contaminated soil. All soil samples were analyzed for gasoline
range organics and diesel range organics (EPA Method 8015C, TPH GRO/TPH DRO).
The only previous report prepared for NCDENR was the 24-Hour UST-61 Report.
C. Site Check Report
A site check report has not been completed.
D. UST Closure Report
The UST-2 form is included in Appendix A.
1. Describe preparations for closure including steps taken to notify authorities, permits obtained, and steps
taken to clean and purge the tanks.
A Utility locate request was made to NC One-Call. Seramur & Associates personnel made site visits to
mark the proposed excavation area. The atmosphere in the USTs was checked for explosive vapors with an
Explosimeter. The Lower Explosive Limit (LEL) readings for the gasoline USTs were below 10%. The
atmosphere inside the USTs were rendered inert with carbon dioxide by placing dry ice (1.5 lbs./100
gallons) in the tanks on October 12 and 13, 2016. A UST closure permit was obtained from the County
Fire Marshal. A Health and Safety Plan was prepared for the closure work and a safety meeting was
conducted in the morning prior to commencing work.
5
Residual liquids (water w/some fuel) were removed from UST 3 by Petroserve, Inc. prior to the closures.
973 gallons of a gasoline/water mix were removed from the tank. UST 1 and UST 2 were empty.
The tanks were excavated and removed from the excavation. Fred Reeves Construction transported the
three tanks to their construction yard for cleaning and preparation for recycling.
2. Describe the closure procedure referencing site and sampling location maps and cross-sections presented
in Section J of this report. Clearly state how the selection of sample types and locations was influenced by
the nature of the stored substance, the type of initial alarm or cause for suspicion, the type of backfill, the
depth to groundwater, and other factors appropriate for identifying the presence and source of a release. If
presence of groundwater or bedrock require the installation and sampling of monitoring well(s), describe
the process.
Soil was excavated from the sides and one end of each UST. The USTs were then removed from the
excavation using chains and the trackhoe. Soil samples were collected from below each UST (Figures 4
and 5). One additional composite soil sample was collected from the contaminated soil stockpiles. These
soil samples were analyzed for gasoline range organics and diesel range organics (EPA Method 8015B,
TPH GRO/TPH DRO).
Soil samples from the excavation were collected using both the trackhoe bucket and decontaminated hand
auger buckets. The extent of the excavation and locations of soil samples are shown on Figures 3, 4 and 5.
All soil samples were collected while wearing a new pair of disposable Nitrile gloves. The soil samples
were placed in containers provided by the lab, labeled and placed on ice. A chain of custody was initiated
and the samples were transported to Prism Labs Inc. in Charlotte, NC for analysis.
The selection of sample types and locations was not influenced by the nature of the stored substance.
Depth to groundwater is not known. There was no evidence of groundwater in the excavation. The UST
excavation was backfilled with clean soil from the excavation as well as clean fill obtained by Fred Reeves
Construction.
3. Note the amount of residual material pumped from the tank and describe the storage, sampling and
disposal of the residual material and the disposal of the tank, pumps and piping.
Residual fuel was removed from UST 3 by Petroserve, Inc. prior to the closures. 973 gallons of a
gasoline/water mix were removed from the tank. UST 1 and UST 2 were empty.
The tanks were excavated and removed from the excavation. Fred Reeves Construction transported the
three tanks to their construction yard for cleaning and preparation for recycling.
4. If a release is determined, document initial response actions.
A petroleum odor and staining was noted around the tanks for the three USTs. Soil excavation was limited
to the volume of soil that was necessary to remove the USTs from the ground. Three USTs were closed
and removed from the site. Contaminated soil associated with the leakage from the tanks was stockpiled
onsite. Approximately 42 cubic yards of contaminated soil was stockpiled onsite and later transported to
Environmental Soils, Inc. in Lattimore, NC.
Elevated concentrations of gasoline range organics and diesel range organics were detected in samples S-1
and S-4. Gasoline range organics were detected above the NCDENR action level in all samples collected
from under the tanks except for S-8 and S-10. Diesel range organics were detected above the NCDENR
action level only in samples S-1, S-4 and S-9.
A 24-hour report was prepared for NC DENR.
5. Document any soil excavation activities.
6
Soil was excavated from the sides and one end of each UST. The USTs were then removed from the
excavation using chains and the trackhoe. If petroleum vapors were detected in soil removed from the
excavation, it was stockpiled onsite and later transported to a remediation facility.
6. Document site investigation.
The trackhoe buckets of soil removed from the UST excavation were screened in the field for petroleum
vapors with a Photocheck 100 photoionization detector. The photoionization detector is calibrated with a
100-ppm isobutylene calibration gas mixture. Soil containing petroleum vapors was stockpiled onsite.
Soil consisted of sandy silt to a depth of about 9 feet.
Soil sample locations are shown on Figures 4 and 5. North-South and East-West cross-sections of the UST
system are shown in Figure 5. Soil samples were collected on October 12 and 13, 2016. The sample time
is listed on the Chain of Custody Record.
Depth to groundwater is not known. There was no evidence of groundwater in the excavation. The UST
excavation was backfilled with clean fill from the tank pit and clean fill obtained by Fred Reeves
Construction.
The hand auger buckets were decontaminated with non-phosphate detergent, distilled water and
isopropanol. Horizontal location and depth of the soil samples was measured with a fiberglass tape,
estimating right angles and referencing site features.
Soil samples were stored on ice and shipped to Prism Labs in Charlotte, NC via Federal Express.
Elevated concentrations of gasoline range organics and diesel range organics were detected in samples S-1
and S-4. Gasoline range organics were detected above the NCDENR action level in all samples collected
from under the tanks except for S-8 and S-10. Diesel range organics were detected above the NCDENR
action level only in samples S-1, S-4 and S-9.
7. Present conclusions and recommendations, referencing maps
The source of soil contamination was the three USTs. Petroleum constituents were detected at
concentrations above the NCDENR action levels in the base of the UST excavation.
Elevated concentrations of gasoline range organics and diesel range organics were detected in samples S-1
and S-4. Gasoline range organics were detected above the NCDENR action level in all samples collected
from under the tanks except for S-8 and S-10. Diesel range organics were detected above the NCDENR
action level only in samples S-1, S-4 and S-9.
Free product has not been encountered at the site. The next assessment phase required by NCDEQ would
be an LSA report.
E. Free Product Investigation and Recovery Report
Free product was not observed during the UST closure.
F. Groundwater and Surface Water Investigation
There was no groundwater or surface water investigation completed during the UST closure.
G. Initial Response and Abatement Action
Contaminated soil associated with the release from the USTs was stockpiled onsite. Approximately 40
cubic yards of contaminated soil was stockpiled. Nine soil samples (S-1 through S-6 and S-8 through S-10)
were collected from within the excavation for TPH GRO/DRO analysis. One additional composite sample
was collected from the soil stockpiles. A 24-hour report was prepared for NCDENR.
7
H. Excavation of Contaminated Soil
A petroleum odor and staining was noted around the tanks for the three USTs. Soil excavation was limited
to the volume of soil that was necessary to remove the USTs from the ground. The three USTs were
collected and removed from the site. Contaminated soil associated with the leakage from the tanks was
stockpiled onsite. Approximately 40 cubic yards of contaminated soil was stockpiled onsite.
I. Conclusions
The source of soil contamination was the three USTs. Petroleum constituents were detected at
concentrations above the NCDENR action levels in the base of the UST excavation.
Elevated concentrations of gasoline range organics and diesel range organics were detected in samples S-1
and S-4. Gasoline range organics were detected above the NCDENR action level in all samples collected
from under the tanks except for S-8 and S-10. Diesel range organics were detected above the NCDENR
action level only in samples S-1, S-4 and S-9.
Free product has not been encountered at the site. The next assessment phase required by NCDEQ would
be an LSA report.

Standard Operating Procedures
The atmosphere in the USTs was checked for explosive vapors with an Explosimeter. The Lower Explosive Limit
(LEL) readings for the gasoline USTs were below 10%. The atmosphere inside the USTs were rendered inert with
carbon dioxide by placing dry ice (1.5 lbs./100 gallons) in the tanks on October 12 and 13, 2016. A Health and
Safety Plan was prepared for the closure work. A safety meeting was conducted prior to commencing work.
Soil samples collected from the excavation were collected out of the trackhoe bucket and with decontaminated hand
auger buckets. The hand auger buckets were decontaminated with non-phosphate detergent and distilled water and
isopropanol rinses.
Soil samples collected for laboratory analysis were placed in laboratory sample jars with Teflon-lined lids; chilled
and Chain-of-Custody record was initiated. Soil samples were transported to Prism Labs Inc. in Charlotte, North
Carolina for analyses. A new pair of disposable Nitrile gloves was worn while collecting each sample. The depth
and horizontal locations of the soil samples were identified by measuring with a fiberglass tape, estimating right
angles and referencing site features.
