As part of the excavation for the footing for the redevelopment of the property, a tank was
discovered. As the removal of the 550 gallon heating oil UST proceeded, a release of the
contents of the tank was evident. A soil sample was taken and delivered to the laboratory
showed 8530 ppm for diesel range hydrocarbons. A report of the release was made to the NC
DEQ via a UST Form 61 "24 hour" report emailed to NC DEQ on 2/28/19. The cause of the
release is suspected to be the deterioration of the UST. The amount of the release is unknown.
IAA Report 3416 Little Hope Road Page 1

B. Site History and Characterization
UST Owner/Operator Information
The property is owned by Mathew and Rachel Kushner. Shortly after purchasing the
property, the existing structure was demolished. Apparently at some point in the former
home's past it was heated via a fuel oil fired furnace. At the time of this report, it is
unknown as to when the UST was last used.

* Exact date of tank installation unknown
Non -UST Information
There was no indication at the subject site of an aboveground tank or any other non -UST
source of the discovered contamination. There are no known releases from any non -UST
sources.
Release Information
During the removal of the tanks, a confirmation sample was collected and also field screened
via a PID. These activities showed that a release had occurred.
Site Characterization Information
The property is a single family residence in a solely residential area. The predominant soil
type at the site was red to orange silty. The surface topography at the UST location sloped
slightly toward the west. The local area and topography are illustrated in Figure 1, Aerial
Photograph and Figure 2, the USGS map.
The site is located in Charlotte city limits and along with the surrounding properties appears
to utilize municipally supplied water and sewer and/or have access to municipal water and
sewer.
Summary of Initial Abatement
The UST was discovered during the excavations for the footings of a new structure. Work
was delayed was removed, and contamination was discovered. A 24-Hour Release and
UST Leak Reporting Form was sent to the NC DEQ. The contaminated soil was excavated.
The excavation continued until field checks indicated that the impacted soil had been fully
removed. After this removal, soil samples were collected.
IAA Report 3416 Little Hope Road Page 2

C. Site Check Report
This section is not applicable.
D. UST Closure (Non -Regulated)
Removal of UST Residuals
Prior to any removal activities, the contents of the UST were assessed. According to the
contractor digging the footings, the tank was found to contain liquid (suspected to be water)
that immediately leaked back into pit through holes in the tank as the tank was removed. The
soil contacted by the contents of the tank was part of the over -excavation of contaminated
soil.
UST Removal and Assessment Procedures
A trackhoe was used for the excavation of the UST. The equipment excavated the soil from
above the tank prior to the tank being removed from the excavation. When INENCO arrived,
the excavated soil was assessed via olfactory means and a PID for indications of a release as
it was being stockpiled for later use. A small amount of soil was removed from the
excavation and a sample was collected. It was apparent during the removal and sampling of
the UST that a release of the contents had occurred.
UST Disposal
The UST was disposed of soon after the time that the tank was removed. The tank was
disposed of by CERT through Auto Parts U Pull and Scrap Metal of Charlotte. A copy of the
Certificate of Disposal is included in Appendix E.
UST Closure Site Investigation
UST Closure Field Screening
Soil samples were collected in plastic bags for field checks via the PID. A Mini Rae 2000
photo -ionization detector was used to field screen the soil. The PID was calibrated to display
concentration in units equal to parts per million. First, a supply of zero air, containing no
ionizable gases or vapor, is used to set the zero point. Then, span gas, containing a known
concentration of a photo -ionizable gas or vapor, is used to set the sensitivity. Isobutylene at
100 ppm was used as the span gas. The field screening was done by placing the PID next to
the soil that had been removed and observing the meter to determine if contaminated soil was
present. In addition, soil samples were placed in plastic bags and allowed to warm and then
were field analyzed.
UST Release Confirmation Samples
The release confirmation sample was collected from the open excavation utilizing the bucket
of the trackhoe. The grab sample was collected from soil not in contact with the trackhoe
bucket. The sample collected from undisturbed soils was immediately placed into laboratory
provided containers/preparations. Quality control measures are documented by the
laboratory in their analytical report in Appendix B.
IAA Report 3416 Little Hope Road Page 3

UST Release Confirmation Sample Results
The results of the soil sampling confirmed that contamination was present and that a release
had occurred. Laboratory results of the sample indicated 88.6 mg/kg Gasoline Range
Organic (GRO) compounds and 8530 mg/kg Diesel Range Organic (DRO). The laboratory
reports for these results are located in Appendix B.
UST Closure Conclusions
The operation of the USTs caused a release of its contents as documented in these assessment
activities. Initial abatement actions were initiated as documented in this report.
E. Free Product Investigation and Recovery Report
No free product was discovered; therefore, this section is not applicable.
F. Groundwater and Surface Water Investigation
Groundwater was not discovered during the excavation; therefore, this section is not
applicable.
G. Initial Response and Abatement Action
Abatement activities took place after the discovery of the release. This is documented in
following sections.
H. Excavation of Contaminated Soil
Over -Excavation Activities
After removal of the UST, on 2/27/2019 soil excavation commenced in an effort to remove
soil to the extent of contamination. Soil checks using the PID and olfactory clues were used
to guide the excavation. The overall final dimensions of the excavation were 20 feet by 21
feet by 11 feet deep. The removed soil was placed directly into trucks for disposal. The
excavation was sampled via the trackhoe with a sample labeled Bottom Sample taken from
the center floor of each tank pit area beneath the former location of each UST at a depth of
11 feet. Soil samples were labeled South Wall Sample, West Wall Sample, North Wall
Sample, and East Wall Sample and taken from the area of the wall where it seemed during
the closure activities that contamination would be most likely to be present. Each of these
samples was collected from a depth of approximately 9' feet below land surface. The soil
samples were checked for the presence of constituents found by EPA Methods 8260, 8270
and MADEP EPH & VPH. The location of each sample along with the overall excavation is
illustrated in Figure 3. All samples were collected as previously described. Neither
groundwater nor bedrock was encountered during the over -excavation activities.
IAA Report 3416 Little Hope Road Page 4

Over -Excavation Soil Removal /Disposal
Disposal of the contaminated soil took place on 2/27&28/2019. Three covered dump truck
loads were transported to Environmental Soils, Inc. in Lattimore, NC. A summary of these
activities is shown in the following table. The Disposal Manifest is included as Appendix C.

Over -Excavation Stockpile Sample Results
Impacted soil was loaded directly onto a truck for disposal. The tank sample was also used
as a stockpile sample forth purposes of disposal. Laboratory results of this sample indicated
88.6 mg/kg for GRO and 8530 mg/kg DRO. The laboratory report for these results is located
in Appendix B.
Over -Excavation Sample Results
Bottom
After the removal of the affected soil (a total of about 40 tons), a sample was collected along
the floor of the excavation directly beneath each former UST location at a depth of 11 feet.
This sample was denoted Bottom Sample. The laboratory results indicated no results above
Soil -to -Groundwater Maximum Soil Contaminant Concentrations (MSCCs). All results are
quantified in Table 1, Soil Sample Results.
South Wall
Additionally, a sample was collected from along each of the excavation walls at the wall's
approximate lateral center at a depth of 9' feet. The sample collected along the south side of
the excavation was denoted South Wall sample. The laboratory results indicated no results
above Soil -to -Groundwater Maximum Soil Contaminant Concentrations (MSCCs).
West Wall
The sample collected along the west wall of the excavation was denoted West Wall sample.
The laboratory results indicated no results above Soil -to -Groundwater Maximum Soil
Contaminant Concentrations (MSCCs).
North Wall
The sample collected along the north side of the excavation was denoted North Wall Sample.
This sample also indicated no results above Soil -to -Groundwater Maximum Soil
Contaminant Concentrations (MSCCs).
IAA Report 3416 Little Hope Road Page 5

East Wall
The sample collected along the east wall of the excavation was denoted East Wall sample.
This sample also indicated no results above Soil -to -Groundwater Maximum Soil
Contaminant Concentrations (MSCCs).
I. Conclusions and Recommendations
The primary source (UST system) of the contamination and the secondary source (affected
soil) of contamination have been removed from the site. Based on this the property should
be subject to "no further action".

lines an excluded.)
Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above
the shear valve)
Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that
connects the submersible turbine pump to the tank
Delivery Probicm: identifies mlcawes that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfill. )
