B. EXECUTIVE SUMMARY
SUMMIT was retained by a perspective purchaser to complete due diligence studies of the subject
property located at 9920 Mallard Glen Drive, Charlotte, North Carolina. The site parcel at that time
was identified by Mecklenburg Parcel ID: 02903112. A recent recombination plat was recorded
and the subject property is now a portion of Mecklenburg County Parcel ID: 02903122.
The subject property was observed to contain a single-family home constructed in 1956. One
water supply well and one 500-gallon heating oil UST was observed in the October 2019 site
reconnaissance. The water supply well was out of service and the home appeared vacant. The
water well was subsequently abandoned prior to UST closure in preparation for future site
development. The residential home was demolished during the completion of this IAA. A limited
assessment of the UST was completed to determine if a release had occurred. Multiple soil
borings were completed adjacent to the UST. One soil sample submitted for analysis documented
petroleum impacts with Naphthalene above the MSCCs Soil to Groundwater at 5 feet below
ground surface. A release notification was submitted to NCDEQ in April 2020.
In December 2020 UST closure by removal and Initial Abatement Actions were conducted. 275-
gallons of petroleum contact liquids was removed from the tank prior to closure. The UST was
removed form ground utilizing an excavator and secured for transport and disposal by T K Tank
Services of Sumter, SC. Visual staining and petroleum odors were noted in the base of the
excavation. 2 feet of soils from all sidewalls and 4 feet of soils below the UST was excavated from
around the UST and transported off -site for disposal by T K Tanks Services. Excavation was
terminated when field screening indicated minimal VOC detections. A total of 6 tons of soil was
transported offsite in the Initial Abetment Action in December 2020. Soil samples were collected
from the sidewalls at approximately 5 feet below ground and one soil sample was collected from
the base of the excavation at 8 feet below ground surface. Samples were submitted for VOC, SVOC
and EPH/VPH analysis in accordance with DEQ guidance. Results reported Benzo (a)pyrene above
Soil to Groundwater MSCCs in the western and southern sidewalls. Results reported 2-

Mythylnaphthalene, Phenanthrene, C9-C18 Alphatics and C9-C22 Aromatics above Soil to
Groundwater MSCCs in the base of excavation. Additionally, C9-C22 aromatics was identified in
the northern and western sidewalls above the Soil to Groundwater MSCCs. Based on the results,
additional abatement was recommended.
In February 2021, SUMMIT directed the client provided grading contractor to over excavate the
UST basin in an effort to fully remove soil impacts. An additional 22 tons of soil was removed from
the initial excavation sidewalls and base and transported to Republic Landfill for disposal. The
western sidewall was excavated an additional 5 feet, northern and southern sidewalls an additional
4 feet and the base was lowered an additional 3 feet. Confirmation soil samples were collected
from the western wall and base of excavation. Due to a sampling error, the northern and southern
sidewalls were not resampled following abatement actions. Results of the collected confirmation
samples from the western sidewall and base reported no impacts above regulatory concentrations
remained. On April 26, 2021, the northern and southern sidewalls were re -sampled for
confirmation of full removal of impacts. These confirmation samples were analyzed for the
compounds that originally reported to exceed the corresponding Soil to Groundwater MSCCs.
Results of the collected confirmation samples from the northern and southern sidewalls reported
no impacts above regulatory concentrations remained.
No water supply wells are located within 150 feet of the UST basin. Groundwater was not
encountered during IAA. Bedrock was not encountered in the UST basin during IAA.
Based on the Initial Abatement Actions taken and the results of confirmation sampling, SUMMIT
requests closure with No Further Action at this time.

C.4. Release Information
SUMMIT personnel visited the site on November 8, 2019. The Heating Oil UST was observed to be
located near the southeast of the home near the driveway. Utilizing a soil probe, SUMMIT
personnel determined the size of the UST to be approximately 8 feet in length and 4 feet in
diameter. SUMMIT completed five (5) geo-probe borings around the UST. Boring SB-1 and SB-2
were located at the approximate end of the UST. SB-3 was located on the downgradient side of the
UST. SB-4 and SB-5 were offset away from the UST. Each soil boring was extended to 10 feet below
ground surface (bgs). Typical brown -tan sandy Silts were encountered in the soil borings. SB-2
exhibited petroleum soil staining, odors and positive detections of field screening equipment from
3 to 6 ff bgs. Soil sample SS-1 was collected from 5 ft bgs and soil sample SS-2 collected from 7 ft
bgs. The collection of SS-1 and SS-2 will help define the vertical extent of impacts. SB-4 and SB-5
were spaced out in 2 directions from SB-2 in order to help define the lateral extent of impacts. SB-4
did not display indicators of petroleum impact. SB-5 detected slight petroleum staining and odors
at approximately 5 ft bgs. SS-3 was collected from SB-5 at 5 ft bgs. Typical brown -tan sandy Silts
were encountered in the soil borings. Soil samples collected were bottled for submittal to a North
Carolina certified laboratory for analysis of BTEX, Naphthalene and Poly -cyclic Aromatic
Hydrocarbons (PAHs). It should be noted that groundwater was not encountered in any boring.
On December 8, 2020 SUMMIT directed the removal of the UST and excavation of impacted soils
by T K Tank Services of Sumter, SC. Soil staining and corrosion pinholes on the tank ends were
observed during tank removal. 6 tons of petroleum impacted soil was excavated from the base of
excavation and sidewalls into a truck for transport and disposal at T K Services treatment facility.
Closure samples were collected from the 4 sidewalls and base of excavation. Results of the closure
sampling reported elevated EPH/VPH remained in the base and western side wall of the
excavation. On February 24, 2021, the grading contractor excavated additional base soils and from
sidewalls for transport and disposal by Centurion at Republic Landfill. An additional 22 tons were
removed and manifested to Republic CMS Landfill. Closure samples SB-6 and SB-7 were collected
to confirm clean closure from the western sidewall and base of excavation. The northern and
southern sidewalls were over excavated however samples were not collected from these locations

J.2. Excavation
Tank removal and abatement actions were initiated on December 8, 2020. T& K Tank Services
mobilized to the subject property with a excavator, pump truck and dump truck. The UST fill port
was utilized to remove liquids from the tank prior to removal. 257-gallon of liquid petroleum and
petroleum contact water were purged from the tank. Excavation of the tank started with the
exposing the top of the steel 500-gallon UST. Soils from the sides of the UST were then removed,
exposing the sides of the UST. The UST was then hooked to a chain and pulled from the UST basin.
Corrosion pinholes were noted along the base and ends of the UST. Soil staining along the base
and eastern sidewalls was observed. Soils of the basin consisted of hard silts and clays. SUMMIT
directed the excavation of visually impacted soils from the basin. Field screening utilizing a rented
calibrated Mini -Rae 3000 PID was conducted on the remaining exposed sidewalls and base of the
UST basin. Excavation continued to until field screening results indicated an absence of VOC
compounds. A total of 6 Tons of soil was removed for the UST basin and transported to a
treatment facility operated by T K Tank Services in Sumter, SC. The UST was crushed and recycled
by T K Tank Services. The initial excavation measured 8' x 12'x 8' (LxWxD). Post excavation
sampling indicated impacted soils remained following the initial abatement/closure activities.
On February 24, 2021 SUMMIT directed a grading contractor provided by the site developer to
over excavate the base and sidewall of the UST basin that reported elevated EPH/VPH. The base of
the excavation was excavated to an approximate depth of 12 feet below ground surface. The
western sidewall was excavated an additional 5 feet. The northern and southern sidewalls were
excavated an additional 4 feet. The eastern sidewall was excavated an additional 2 feet. A total of
22 tons was transported to Republic CMS Landfill for disposal by Centurion. The resulting
excavation following abatement was approximately 15' x 20'x 12' (LxWxD).
J.3. Post Excavation Sampling
SUMMIT collected four (4) soil samples from the sidewalls of the tank basin and one (1) soil
sample from the base of the excavation on December 8, 2020. The sidewall samples were

collected at approximately 5 feet from the top of the excavation. The bottom sample was collected
from the center of the tank basin.
Samples SB-1, 2, 3, 4 and 5 were collected from the resulting excavation. Figure 3A and 3B
documents the location of the samples collected. Samples were submitted for VOC, SVOC, EPH and
VPH per DEQ requirements. Sample results indicated elevated EPH and VPH remained in the
northern, southern, western sidewalls and base of excavation. On February 24, 2021 SUMMIT
directed a grading contractor provided by the site developer to over excavate the base and sidewall
of the UST basin that reported elevated EPH/VPH. The base of the excavation was excavated to an
approximate depth of 12 feet below ground surface. The western sidewall was excavated an
additional 5 feet. The northern and southern sidewalls were excavated an additional 4 feet. The
eastern sidewall was excavated an additional 2 feet. A total of 22 tons was transported to Republic
CMS Landfill for disposal by Centurion. The resulting excavation following abatement was
approximately 15' x 20'x 12' (LxWxD). Samples SB-6 and SB-7 were collected from the base of
excavation and western side wall following the additional removal. Samples were not collected at
this time from the northern and southern sidewalls due to collection error. On April 26, 2021 SB-8
and SB-9 were collected from the northern and southern sidewalls and analyzed for the
compounds that previously exceeded the Soil to Groundwater MSCCs. The collected confirmation
samples from base of excavation and sidewalls indicated successful removal of impacted soils from
these locations.
J.4 Soil Investigation
New, clean disposable latex gloves were used for the collection of each soil or groundwater
sample. Samples collected for laboratory analyses were placed in laboratory -supplied containers
with the sampler's name, time and date the sample was collected, and laboratory analyses to be
performed. The samples were packed on ice and taken to Pace Analytical Services, LLC in
Columbia, South Carolina. For a drawing detailing the locations of the soil samples, please refer to
Figure 3.0 in the appendices. Groundwater was not encountered in the excavation. The samples
were grab samples. Standard chain -of -custody procedures were followed.

Field screening was based on visual and olfactory observations. In addition, soil samples were
taken from the excavation and were analyzed onsite using an calibrated Mini Rae 3000 handheld
PID w/ VOC Measurement. Prior to each analysis, the PID was allowed to equilibrate to the area
temperature and ambient air conditions.
J.S. Disposal
Approximately 6 tons of contaminated soils were removed from the site on December 8, 2020
and taken to T K Tank Services in Sumter, SC for treatment at the permitted facility.
Approximately 22 tons of contaminated soils were removed from the site on February 22, 2021
and taken to Republic Service, Inc. in Concord, NC.
K. CONCLUSIONS
Due diligence studies conducted for the property identified a petroleum release associated with
the home heating oil tank at 9920 Mallard Glen Drive, Charlotte, North Carolina. The first
abatement action occurred in December 2020 during UST closure, with a total of 6-tons of soil
removed from the UST basin for disposal at a treatment facility in Sumter, SC. EPH/VPH
exceedances remained and a second abatement action was conducted in February 2021, with a
removal of an additional 22-tons of soil.
Confirmation sampling conducted confirms that the sidewalls and base of excavation are below
regulatory levels.
No free product was encountered. Groundwater was not encountered. Competent bedrock was
not encountered.
SUMMIT concludes that the Abatement Actions and UST closure were successful.

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

9920 Mallard Glen Drive
Charlotte, Mecklenburg County, North Carolina
SUMMIT Project No. 5778.500
SUMMIT ENGINEERING, LABRATORY & TESTING, P.C. (SUMMIT) has completed a limited
assessment of a Home Heating Oil (HHO) underground storage tank (UST) at 9920 Mallard Glenb
Drive, Mecklenburg County, North Carolina. SUMMIT personnel conducted the site field work on
November 8, 2019.
The site is irregular in shape and was noted to be comprised of one (1) parcel totaling approximately
1.49 acres in area. The site is developed with one (1) single family home and associated outbuildings.
The residential structure is approximately a 1,2464 SF home, constructed in 1956.
SUMMIT personnel visited the site on November 8, 2019. The HHO UST was observed to be
located near the southeast of the home near the driveway. Utilizing a soil probe, SUMMIT personnel
determined the size of the UST to be approximately 8 feet in length and 4 feet in diameter. SUMMIT
completed five (5) geo-probe borings around the UST. Boring SB-1 and SB-2 were located at the
approximate end of the UST. SB-3 was located on the downgradient side of the UST. SB-4 and SB-
5 were offset away from the UST. Each soil boring was extended to 10 feet below ground surface
(bgs). Typical brown -tan sandy Silts were encountered in the soil borings. SB-2 exhibited petroleum
soil staining, odors and positive detections of field screening equipment from 3 to 6 ff bgs. Soil
sample SS-1 was collected from 5 ft bgs and soil sample SS-2 collected from 7 ft bgs. The collection
of SS-1 and SS-2 will help define the vertical extent of impacts. SB-4 and SB-5 were spaced out in
2 directions from SB-2 in order to help define the lateral extent of impacts. SB-4 did not display
indicators of petroleum impact. SB-5 detected slight petroleum staining and odors at approximately
5 ft bgs. SS-3 was collected from SB-5 at 5 ft bgs. Typical brown -tan sandy Silts were encountered
in the soil borings. Soil samples collected were bottled for submittal to a North Carolina certified

laboratory for analysis of BTEX, Naphthalene and Poly -cyclic Aromatic Hydrocarbons (PAHs). (It
should be noted that groundwater was not encountered)
Laboratory results were compared to North Carolina Department of Environmental Quality
(NCDEQ) Maximum Soil Contaminant Concentrations (MSCCs). Table 1.0 attached to this
document summarizes the detections. As indicated on the attached summary table, sample SS-1,
collected at 5 ft bgs adjacent to the northern tank end, detected the presence of petroleum compound
Naphthalene above the established Soil to Groundwater MSCC. No detections were reported for SS-
2 or SS-3.
Based on the results of our inspection, SUMMIT concludes that the HHO USTs has released
petroleum products into the surrounding soils. Per NCDEQ regulations, the UST owner is required
to submit a 24-Hour Release notification (Form UST-6 1). A copy of this form is attached to this letter
and a copy can be obtained at https://deq.nc.gov/about/divisions/waste-management/ust/forfns. A
copy of this limited assessment should be submitted along with the UST 61 to the NCDEQ
Mooresville Regional Office.
SUMMIT recommends the removal and proper closure of the UST in accordance with NCDEQ UST
guidelines. Based on the detections of concentrations above the established Residential MSCCs, the
Notice of Residual Petroleum (NRP) would be required if soils are to remain in place following UST
removal. Soil over -excavation would be required in order to avoid an NRP and receive a No Further
Action status from NCDEQ.
This letter includes a description of the methodology of our investigation and a summary of our
findings and conclusions. If you have any questions regarding our assessment of the subject property,
our conclusions or recommendations, please do not hesitate to call us at [phone].

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

Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Where applicable, all soil sample analysis are reported on a dry weight basis unless flagged with a "W"
qualifier
If you have any questions regarding this report please contact the Pace Project Manager listed on the
cover page.
VOCs by GC/MS
The laboratory control sample duplicate (LCSD) for analytical batch 76782 exceeded acceptance criteria
for : Methylcyclohexane and tetrachloroethene. These analytes were biased high and were not detected
in the samples affected.
VPH
Surrogate recovery for the following samples was outside control limits: VL08062-002, VL08062-003,
VL08062-005. Evidence of matrix interference is present; therefore, re -extraction and/or re -analysis was
not performed.
SVOCs by GC/MS
The following sample was diluted due to appearance or color: VL08062-001. The LOQ has been
elevated to reflect the dilution.
Sample -005 has been analyzed at a 10X dilution due to large detections of the target compounds. This
large dilution caused a surrogate to recover outside of method criteria. No corrective action is required as
it is known that dilutions of 5X and greater may impact surrogate recoveries.

Lot Number: WC01007
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Where applicable, all soil sample analysis are reported on a dry weight basis unless flagged with a "W"
qualifier
If you have any questions regarding this report please contact the Pace Project Manager listed on the
cover page.
SVOCs by GC/MS
The following samples were diluted due to appearance or color: WC01007-001, WC01007-002. The LOQ
has been elevated to reflect the dilution.
The method blank associated with batch 84430 yielded a "J" value detection for Di-n-butyl phthalate. No
corrective action is required as this is an estimated value recovered below the LOQ. The LCS associated
with this batch recovered Butyl benzyl phthalate above method criteria. No corrective action is required as
all associated samples are non -detect for this compound.

Trudy,
Good afternoon. We submitted the attached release notification last May for the heating oil tank at 9920 Mallard Glen
Drive. I cant seem to locate a incident # for this release on laserfiche or DWM GIS. Not sure this one got logged in as I
initially sent this over to Dan.
Either way, our client finely moved forward with closure earlier this year and we need to submit the documentation for
closure. Soil was excavated and we were able to get clean margins on all 4 sidewalls and base. Looking at the updated
Corrective Action report formats, it looks like the Initial Abatement Action report is no longer presented. Would we be
going the format for Soil Cleanup with Closure Request (#12)? Since this appears new I wanted to reach out and get
your advise on how to proceed. Could you point me to a recent approved heating oil tank closure site that I can look up
and review to ensure I cover all my bases. I will have a few more of these to produce so I want to be sure I get you
exactly what you are needing.
Feel free to call me on my cell at 803-230-5087 anytime.
Thank you,
Patrick

Dan,
I hope you are well. I have attached a release notification for a heating oil UST we assessed in November last year. Our
client requested the owner complete the attached, however it did not get completed. We are submitting on their behalf
prior to real-estate transaction. If there is a person or admin I should be sending these too, please let me know.
Thanks
Patrick
