3. Non -UST spills at the site:
No non -UST spills are known to have occurred at the site.
4. Description of release:
A suspected release was identified during the removal of two 550-gallon heating
oil USTs (UST 1 and UST 2) on December 17 and 19, 2018. The North Carolina
Department of Environmental Quality (DEQ) was notified of the release on
January 2, 2019 via a 24-Hour Release and UST Leak Reporting form (UST-6 1).
A copy of this form is provided in Appendix A.
The suspected release was confirmed on December 19 and 31, 2018 upon receipt
of the laboratory analytical data for the closure soil samples. UST closure soil
data are discussed further in Section D below.
5. Site characteristics:
The Site consists of an approximate 2.45-acre parcel of land that is developed
with a 910-square foot (sq ft) former hair salon, a 1,782-sq ft former coffee shop,
and a 1,774-sq ft former flower shop that were constructed between 1931 and
1955. A site location map is included as Figure 1, and a site map is included as
Figure 2.
The subject property is located in the Charlotte Belt of the Piedmont
Physiographic Province of North Carolina, according to the Geologic Map of
North Carolina dated 1985. In the site area, underlying bedrock is composed of
metavolcanic rock consisting of interbedded felsic to mafic tuffs and flowrock.
The land surface of the area is generally characterized as gently sloping, which
may become moderately steep where intersected by streams.
In the Piedmont, the bedrock is overlain by a mantle of weathered rock termed
saprolite or residuum. The saprolite consists of unconsolidated clay, silt, and sand
with lesser amounts of rock fragments. Due to the range of parent rock types and
their variable susceptibility to weathering, the saprolite ranges widely in color,
texture, and thickness. Generally, the saprolite is thickest near interstream divides
and thins toward streambeds. In profile, the saprolite normally grades from
clayey soils near the land surface to highly weathered rock above competent
bedrock.
The occurrence and movement of groundwater in the Piedmont is typically within
two separate but interconnected water -bearing zones. A shallow water -bearing
zone occurs within the saprolite, and a deeper water -bearing zone occurs within
the underlying bedrock.
The site is located at an approximate elevation of 780 to 785 ft above mean sea
level. The topographic gradient at the site is generally to the south-southeast
towards an unnamed tributary of Goose Creek located approximately 600 ft south
of the site (Figure 1).

SMA RTE R E NVI RONM ENTAL SOLUTIONS

Visual observations during excavation activities and soil sample collection
indicated that the soil surrounding the UST systems consisted of reddish -orange
silty clay and red/tan clayey silt. Groundwater was not encountered in the
excavations.
6. Initial abatement actions, assessment activities, and corrective actions
performed to date:
In September and October, 2018, H&H conducted Phase I Environmental Site
Assessment (ESA) activities at the site. During this Phase I ESA, H&H observed
one UST on the southeast side of the building at 7400 Matthews -Mint Hill Road,
and a suspected UST was reported to exist on the southwest side of the building
at 7416 Matthews -Mint Hill Road.
The presence of both USTs was confirmed during a ground -penetrating radar
survey on December 17, 2018. H&H contracted South Atlantic Environmental
Drilling and Construction Company (SAEDACCO) of Fort Mill, South Carolina
to remove the USTs on December 17 and 19, 2018. Following the removal of the
USTs, field screening with a photo -ionization detector (PID) indicated the
presence of elevated organic vapor concentrations and petroleum -like odors in
soil beneath the USTs.
Based on the field evidence of impacted soils in the vicinity of the USTs at the
time of closure, soil over -excavation activities were initiated following the UST
removal in accordance with DEQ guidance. The results of the soil over -
excavation activities are discussed in Section D below.
C. Site Check Report
Not applicable.
D. UST Closure Report following UST-12 format and Site Investigation Report for
Permanent Closure or Change -in -Service of UST (UST-2 Form)
1. Preparations for closure including the steps taken to notify authorities,
permits obtained and the steps taken to clean and purge the tanks:
Prior to UST closure activities, H&H contacted the Mecklenburg County Fire
Marshal's office regarding permitting requirements. The Mint Hill representative
of the fire marshal's office indicated that no permit was needed for heating oil
USTs at sites outside of the Charlotte city limits.
On December 17 and 19, 2018, SAEDACCO removed residual fluid which
appeared to be water from the USTs. Prior to removal from the ground, the USTs
were purged with dry ice to remove combustible vapors. Dry ice was applied at
a rate of 1.5 lbs per 100 gallons of tank capacity. A combustible gas indicator
was used to check that potentially combustible vapors dissipated prior to UST
removal.

2. Closure procedures:
Initially, soil was removed from the top and sides of the USTs with a track hoe
so that the tanks could be removed from the ground. Soils encountered during
the excavation were evaluated in the field for the presence of odors, staining, and
for the presence of organic vapor readings with a PID. The PID was calibrated
prior to its use against an isobutylene standard.
Following removal, the USTs were inspected for holes and other signs of damage.
The USTs were single -walled and constructed of steel. Small holes and evidence
of corrosion were observed on the bottom of UST 1 and UST 2.
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:
Prior to the closure activities, approximately 50 gallons of water were removed
from UST 1 using a sump pump, and approximately 125 gallons of water were
removed from UST 2 using a vacuum truck.
The USTs were transported off -site by SAEDACCO for disposal at E-Metals
Metal Recycling, Inc., located in Charlotte, NC. The tank disposal certificate is
included in Appendix B.
4. Initial response actions and initial abatement actions:
Initial response and abatement actions are discussed in the following section.
5. Soil excavation activities:
Approximately 73.15 tons of impacted soils were excavated from the UST basins.
The excavated soil was either directly loaded onto dump trucks or temporarily
stockpiled on plastic sheeting prior to loading onto trucks for transport off -site.
Impacted soils were transported by Elliott Garrison Trucking, Mancuso Trucking
& Grading, and Stegall Trucking to Environmental Soils, Inc. in Lattimore, North
Carolina for proper disposal. A copy of the non -hazardous waste manifests and
certified weight tickets for the excavated soil are provided in Appendix C.
The UST basin at UST 1 was over -excavated to a depth of approximately 10 ft
below ground surface (bgs) based on PID readings. The final dimensions of the
excavation at UST 1 were approximately 9 ft long by 8 ft wide by 10 ft deep.
The UST basin at UST 2 was over -excavated to approximately 14 ft bgs based on
PID readings. The final dimensions of the excavation at UST 2 were
approximately 17 ft long by 12 ft wide by 14 ft deep. Following receipt of
analytical data for initial base, northeast sidewall, and southeast sidewall samples,
two additional over -excavation events were conducted to adequately remove
impacted soil. The third over -excavation event was performed following
demolition of the building at 7416 Matthews -Mint Hill Road which limited access
to impacted soils.

The excavation areas at UST 1 and UST 2 are depicted on Figure 3A and Figure
313, respectively.
Following soil removal, the excavations were backfilled with non -impacted
overburden and imported backfill material. The backfill material was placed in
approximately one -foot lifts in the excavations and compacted using bucket
tamping to bring the excavations up to grade. The backfill material consisted
primarily of red to brown silts and gray sand.
6. Site investigation:
After removal of the USTs and prior to impacted soil excavation, two closure soil
samples were collected in accordance with the Underground Storage Tank
Section Guidelines for Site Checks, Tank Closure, and Initial Response and
Abatement dated March 1, 2007, Change 9 dated February 1, 2019. The closure
soil samples were analyzed for gasoline -range total petroleum hydrocarbons
(TPH-GRO) and diesel -range TPH (TPH-DRO) by EPA Method 8015C. The
approximate locations of the closure samples are depicted on Figure 3A and
Figure 3B.
Analytical data for the closure soil samples indicated the presence of TPH-DRO
(10,000 mg/kg in sample CS-1 collected beneath UST 1 and 1,100 mg/kg in
sample CS-2 collected beneath UST 2) and TPH-GRO (150 mg/kg in sample CS-
1 collected beneath UST 1) at concentrations above the DEQ Action Levels of
100 mg/kg and 50 mg/kg, respectively. Closure soil sample data are summarized
on Table 1, and the laboratory analytical reports are included in Appendix D.
Following over -excavation activities, four confirmation sidewall samples and one
confirmation base sample were collected from the excavation at UST 1 and
submitted for laboratory analysis of volatile organic compounds (VOCs) by EPA
Method 8260B, semi-VOCs (SVOCs) by EPA Method 8270D, and extractable
petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH)
using the Massachusetts Department of Environmental Protection (MADEP)
method. Confirmation sampling results indicate C9-C18 aliphatics (37 mg/kg)
and C9-C22 aromatics (18 mg/kg) in the northeast sidewall sample [NE Sidewall
(8 ft)] at concentrations below the Maximum Contaminant Soil Concentrations
(MSCCs) of 540 mg/kg and 31 mg/kg, respectively. No other compounds were
detected above the laboratory reporting limits in the confirmation samples
collected from the UST 1 excavation.
Initially, four confirmation sidewall samples and one confirmation base sample
were collected from the excavation at UST 2 and submitted for laboratory
analysis of VOCs by EPA Method 8260B, SVOCs by EPA Method 8270D, and
EPH and VPH by the MADEP method. Based on the presence of EPH/VPH
above the soil -to -water MSCC in the samples collected from the base, northeast
sidewall, and southeast sidewall, additional soil excavation was performed and
follow-up confirmation samples were submitted for the same laboratory analyses.

SAAAA-Master Projects\Gary Hunt - GRY\IAA Report\IAA Report (RJC Edits).docz
SMARTER ENVIRONMENTAL SOLUTIONS

The results of analyses of the follow-up confirmation samples did not indicate the
presence of VOCs, SVOCs, EPH, or VPH above the laboratory reporting limits.
All of the soil samples were analyzed by a North Carolina certified laboratory. A
chain -of -custody record was completed for samples collected and included
sample description, date collected, time collected, matrix, sample container
information, and analyses required. The chain -of -custody was signed by H&H
prior to placement in an iced cooler for shipment to the laboratory. Prior to
shipment, the cooler was closed with a seal indicating the H&H representative's
signature and date such that a potential disturbance of the cooler contents could
be detected by the laboratory.
The excavation areas and confirmation soil sample locations are depicted on
Figure 3A and Figure 3B. Post -excavation soil sample data are summarized in
Table 1. Laboratory analytical reports are included in Appendix D.
E. Free Product Investigation and Recovery Report
No free product was observed or recovered during the IAA activities.
F. Groundwater and Surface Water Investigation
No groundwater or surface water investigations were performed as part of UST closure
or IAA activities.
G. Initial Response and Abatement Activities
See Section B.
H. Excavation of Contaminated Soil
See Section D.
I. Conclusions and Recommendations:
In December 2018, two 550-gallon heating oil USTs were removed from the site.
Approximately 73.15 tons of impacted soils were excavated from the UST basins.
Results of final post -excavation soil sampling indicate compound concentrations below
DEQ MSCCs or below the laboratory reporting limits.
Based on the results of the IAA activities, impacted soil has been adequately removed
from both UST basins. As such, H&H recommends that DEQ issue a Notice of No
Further Action for the release incident.

Page 2 of 2
Definitions of Sources
Tank: means the tank that stores the product and is part of the underground storage tank system
Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end -use equipment (Vent, vapor recovery, or fill
lines are 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 Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor
recovery lines, and fill lines)
Unknown: identifies releases for which the source has not been determined
Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser)
Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser)
Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken
components, and components that have changed dimension)
Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust)
Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly
Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells)
Unknown: use when the cause has not been determined

Hi Trudy,
Attached is a copy of the Initial Abatement Action report for the above -referenced site. A hard copy and CD will
be sent out to you today via Fed Ex. Based on the results of post -excavation sampling, I request that a NFA letter
be issued for this incident. Please let me know if you have any questions.
Thanks, and have a great weekend!

Dan,
Hope you're doing well and enjoyed the holidays. Please find the attached UST-61 form for releases from two
unregulated heating oil USTs at 7400 and 7416 Matthews -Mint Hill Road in Mint Hill, NC. As noted on the form,
initial abatement activities are underway. It looks like we are now clean in the excavation for UST-1 but have
more to excavate at UST-2. We are likely excavating to below protection of GW MSCCs on this one due to
proposed future grading/redevelopment in this area by a prospective purchaser of the property. The IAA report
is in progress and will be wrapped up soon after excavation is complete. Please let me know if you have any
questions.
Thanks,
Bo Cappleman, PG, Due Diligence Manager
