B. Site History and Characterization
1. Details regarding the ownership of the former UST is provided in Table B-2.
2. Details regarding information of the former UST are provided in Table B-1.
Based on our review of the available information, the property was undeveloped and
wooded land from at least 1940 until construction of a residential dwelling in 1955. On
January 22, 2018, Summit Engineering, Laboratory, Testing (Summit) advanced two soil
borings on either end of a heating oil UST at the property. The borings were conducted
to assess soil conditions in the vicinity of the tank prior to a sale of the property.
Analytical results of a soil sample from one end of the UST were reported with
concentrations exceeding the Maximum Soil Cleanup Concentrations (MSCCs) for
residential sites. Summit submitted form UST-61, on behalf of the owner, on April 22,
2018.
A Notice of Regulatory Requirements (NORR) was issued for this site by DEQ on
August 29, 2018. A copy of the NORR is attached in Appendix 1.
In February and March 2019, the building was razed. On March 22, 2019, a 550 gallon
heating oil UST was removed from the property. A closure assessment report for the
tank removed March 22, 2019, was completed by ECS Southeast, LLP (ECS) and
prepared in a report dated May 8, 2019. According to the ECS report, following removal
of the UST, a total of 314.35 tons of petroleum impacted soil was removed from the site
for treatment at Environmental Soil, Inc., of Shelby, North Carolina. In addition, 6,756
gallons of contact water was pumped from the excavation following heavy rain. The
contact water was removed for offsite disposal.
Analyses of confirmatory soil samples collected during the tank closure assessment
revealed that none of the parameters tested exceeded the MSCCs for residential sites.
Soil samples collected from the excavation bottom, east, and west walls, exceeded the
soil -to -groundwater MSCC for 1-Methylnaphthalene and Extractable Aromatic (C11-
C22) hydrocarbons. In addition, the sample collected from the bottom of the excavation
exceeded the Volatile Aromatic (C09-C10) hydrocarbons soil -to -groundwater MSCC.
Analysis of a groundwater sample collected during performance of this Limited Site
Assessment (LSA) reported dissolved naphthalene at a concentration of 1.0 ug/L and
total Chromium at a concentration of 6.3 ug/L. All other tested parameters were reported
to be below the sample detection limit.
A street atlas showing the property location is provided as Figure 1. The property
location on a portion of a USGS topographic map is provided as Figure 2.
3. Provide non -UST information:
a. The tank of this report was underground. No evidence of aboveground storage
tanks were observed or reported.

Page No. 4
upon the topographic contours observed on the USGS topographic contour map, the
property slope is generally downward toward the south.
Vegetation: The property surface cover is turf and wooded land along its southern
boundary.
Surface Water: A tributary of Sugar Creek flows along the southern boundary of the
Property.
Wells: No wells were observed at the property.
Buildings: The property is not improved with structures. The Property Layout is
shown as Figure 3.
Surface Cover: The majority of the property surface is covered by turf.
Soil Type: According to the USDA web -based soil survey of Mecklenburg County,
approximately 17 percent of the surficial soil at the property is comprised of Cecil -
Urban Land Complex. The Cecil series consists of very deep, well drained,
moderately permeable soils on ridges and side slopes of the Piedmont uplands. They
are deep to saprolite and very deep to bedrock. They formed in residuum weathered
from felsic, igneous and high-grade metamorphic rocks of the Piedmont uplands.
Slopes range from 0 to 25 percent. Depth to bedrock ranges from 6 to 10 feet or more.
Approximately 59 percent of the surficial soil at the Property is comprised of the
Enon Series. The Enon series consists of very deep, well drained, slowly permeable
soils on ridgetops and side slopes in the Piedmont. They have formed in residuum
weathered from mafic or intermediate igneous and high-grade metamorphic rocks
such as diorite, gabbro, diabase, or hornblende gneiss or schist. Slope ranges from 2
to 45 percent. The solum thickness ranges from 20 to 50 inches. Depth to bedrock is
more than 60 inches. Urban soil is material that has been manipulated or disturbed.
The urban soils typically consist of asphalt and concrete from construction sites.
Approximately 23 percent of the surficial soils at the Property are of the Helena soil
series. The Helena soil series is a very deep, moderately well -drained, with slow
permeability sandy loam, that is usually found on a four percent slop in a cultivated
field.
Depth to and Nature of Bedrock: According to the Geologic Map of North Carolina
1985, the property is located in the Piedmont Physiographic Province. The dominant
rocks in this region are composed mainly of metamorphic and igneous rocks ranging
in age from Precambrian to Paleozoic. Bedrock was not observed at the surface in
the vicinity of the Property. Onsite drilling encountered fine grained sand and silts to
approximately 12-feet below ground. Competent bedrock was encountered from 12
feet to 45-feet (the maximum depth penetrated) below grade.
Depth to groundwater: Drilling at the site revealed depth to water approximately 31-
feet below grade.

A closure assessment report for the tank removed March 22, 2019, was completed by
ECS Southeast, LLP (ECS) and prepared in a report dated May 8, 2019.
According to the ECS report, following removal of the UST, a total of 314.35 tons of
petroleum impacted soil was removed from the site for treatment at Environmental
Soil, Inc., of Shelby, North Carolina. In addition, 6,756 gallons of contact water was
pumped from the excavation following heavy rain. The contact water was removed
for offsite disposal.
Analyses of confirmatory soil samples collected during the tank closure assessment
revealed that none of the parameters tested exceeded the Maximum Soil Cleanup
Concentrations (MSCCs) for residential sites. Soil samples collected from the
excavation bottom, east, and west walls, exceeded the soil -to -groundwater MSCC for
1-Methylnaphthalene and Extractable Aromatic (C 11-C22) hydrocarbons. In
addition, the sample collected from the bottom of the excavation exceeded the
Volatile Aromatic (C09-C10) hydrocarbons soil -to -groundwater MSCC. The
analytical results of soil samples collected during the tank closure are summarized in
Table B-3.

G. Sampling Results
Phase IInvestigation
Responsible parties must perform a Phase I investigation for all releases.
A Phase I investigation includes the installation of one monitoring well in the source area of a
release. Soil samples are to be collected every five feet in the unsaturated zone and should be
analyzed in accordance with the methods specified in Table S of the Guidelines, Analytical
Methods for Petroleum Contaminated Soil. If the water table is encountered at 25 feet or
greater from the land surface, samples for laboratory analysis should be collected every 10 feet
in the unsaturated zone.
On May 30, 2019, CESI supervised the installation of one monitoring well in the location of the
former UST. The boring of the well was conducted by South Atlantic Environmental Drilling
and Construction Company (SAEDACCO) of Fort Mill, South Carolina. The boring of well
MW-1 was advanced in the middle of the former excavation. The boring was advanced using the
hollow stem auger drilling method. The approximate location of the boring is shown on a layout
of the property as Figure 4. The first 12-feet of drilling encountered clean imported soil which
had been backfilled to the excavation conducted by ECS in May 2019. During the drilling, a 2-
foot long, washed, stainless steel spoon was advanced at five-foot intervals. An undisturbed core
was retrieved from each of the spoons for observation and field screening by CESI personnel.
The boring encountered orange silty sand and fine grained fill from grade to approximately 11-
feet below grade. Auger refusal was encountered at 12-feet below grade and no returns were
retrieved in the split spoon sampler. CESI directed SAEDACCO switch to air rotary drilling to
continue the boring to a depth of 45-feet below grade. No undisturbed soil samples were
retrieved during drilling through the rock. For this reason, no soil samples were collected.
Suspect minor fractures were observed at approximately 36-feet and 43-feet below grade. No
water was indicated during drilling or immediately following drilling. CESI instructed
SAEDACCO to install a temporary well consisting of 2-inch diameter PVC. The well was
constructed with 15-feet of 0.010-inch machine slotted PVC. A Number 2 filter sand was placed
around the screen from the bottom of the well to two -feet above the top of the screen. The well
head was covered with plastic and allowed to rest for two days. CESI returned to the site on
June 3, 2019, and measured water in the well at a depth of approximately 31-feet from grade.
Following purge of the well, CESI personnel collected a water sample intro laboratory provided
sample jars. The water samples were immediately placed on ice. The samples were transported
using chain -of -custody protocol to Pace Analytical, Inc. (Pace) of Huntersville, North Carolina.
CESI requested that the samples be analyzed for Volatile Organic Compounds (VOCs) by EPA
Method 8260, Semi-VOCs (SVOCs) by EPA Method 625, and Massachusetts Department of
Environmental Protection (MADEP) Volatile Petroleum Hydrocarbons (VPH) and Extractable
Petroleum Hydrocarbons (EPH), and Total Chromium and Lead. A summary of the analytical
results is provided in Table B-4. Copies of laboratory reports and chain of custody records are
provided in Appendix 5.

Limited Site Assessment July 26, 2019
5628 Closeburn Road, Charlotte, NC Page No. 11
Phase II Investigation (if required)
A Phase H investigation should only be conducted if the release is from a high risk
commercial UST and the levels of groundwater contamination detected in the source area
monitoring well exceed the groundwater standards or interim standards by a factor of 10.
Based on the analytical results, a Phase II investigation is not required.
H. Conclusions and Recommendations
Discuss the risk criteria that apply to the release and identify any other site -specific factors
related to the release that may pose a risk to human health and the environment. Also, discuss
any site -specific conditions or possible actions that could result in lowering the level of risk
posed by the release.
The reported concentration of dissolved naphthalene (1.0 ug/L) and Chromium (6.3 ug/L), in the
water sample collected from well MW-1 do not exceed the North Carolina Groundwater Quality
2L Standards. Based on the lack of dissolved parameters exceeding the 2L standards and the
lack of adsorbed parameters exceeding the residential use MSCC, No Further Action is
recommended.
As this site is in the process of being redeveloped and a pending real estate transaction, CESI, on
behalf of our client would appreciate a speedy review and return letter approving No Further
Action for this incident.
I. Free Product Investigation and Recovery (if applicable)
No free product was observed at the site.

Risk -based Assessment and Corrective Action for
Petroleum Underground Storage Tanks
Byrum Property
5628 Closeburn Road, Charlotte
Mecklenburg County
Incident Number:40792
Risk Classification: Unknown
Information received by this office of the UST Section, Division of Waste Management, on January 29,
2018 confirms a release or discharge from a petroleum underground storage tank (UST) system at the
above -referenced location. Records indicate that you are the owner or operator of this UST system.
Therefore, as a responsible party, you must comply with the initial response and abatement action
requirements of Title 15A NCAC 2L .0404 and, if applicable, the assessment and reporting requirements of
Title 15A NCAC 2L .0405, within the timeframes specified in the attached rules. (Be aware that if the latter
rule is applicable, you must comply with its requirements even if you do not receive formal notification from
the UST Section.)
Initial abatement action requirements include the preparation and submittal of an Initial Abatement
Action (IAA) Report, in accordance with Title 15A NCAC 2L .0404 and the most recent version of the
Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases, within 90 days
of discovery of the release.
Because a release or discharge has been confirmed, a Licensed Geologist or a Professional Engineer,
certified by the State of North Carolina, is required to prepare and certify all reports submitted to the
Department of Environmental Quality in accordance with Title 15A NCAC 2L .0103(e) and 2L .0111(b).

Ms. Gravely,
It was lovely speaking with you this afternoon. As we discussed by phone, the Notice of Regulatory Requirements letter
for the Byrum Property (UST incident number 40792) is attached to this email.
Electronic files for this site can be found on Laserfiche at the following link for viewing and downloading,

Below you will find some general information about home heating oil underground storage tanks:
Home heating oil underground storage tanks are not and haven't been regulated in the state of North Carolina. The UST
section only has records of those that have been reported to our agency. These reports a generally result from
notifications of contamination or tank removals at properties where parties are seeing "no further action" status. Home
heating oil tanks are non -regulated, non-commercial underground storage tanks (USTs) that are exempt from the
"technical regulations" (e.g., leak detection monitoring, corrosion protection, spill and overfill control) that apply to
regulated USTs. Even though home heating oil tanks are exempt from these technical regulations, sampling and cleanup
regulations may apply if there is a leak or spill from your tank. If there is no evidence of a release, then there is no need
to report to the UST Section. The links below provide additional information.
If a leak is discovered under the current ownership of the property, the current property owner is considered the
responsible party for clean-up. Many companies do environmental work related to underground storage tanks.
Typically, they can be found in the yellow pages of a telephone book under "Environmental Consultants." The DWM UST
Section provides a list where companies that do environmental work can provide their information. This list is called the
"UST Service Provider Listing" it is located at http://deg.nc.gov/about/divisions/waste-management/ust/service-
provider-listing. When choosing a company, we recommend getting several estimates and references. Site assessments
and cleanup work must be conducted under the responsible charge of a licensed geologist or professional engineer.
Please note that before you sell, transfer, or request a "No Further Action" determination for a property that has
not been remediated to below "unrestricted use" standards, you must file a Notice of Residual Petroleum
("Notice") with the Register of Deeds in the county where the property is located (NCGS 143B-279.9 and 14313-
279.11).

Good Morning Trudy,
Hope you are having a good summer. Please find attached an LSA for the Byrum Property located at
5628 Closeburn Road, Charlotte, NC(Incident 40792).
Soil contamination was discovered in 2018 during due diligence assessment of a heating oil UST. The
UST was closed by removal this spring and impacted soil was removed. However, confirmation soil
sampling revealed concentrations exceeding soil -to -groundwater. The LSA did not encounter
groundwater above bedrock. Using air rotary methods, a well was installed to 45-feet below
grade. This well produced water which was sampled for the LSA. Naphthalene was reported at 1.0
ug/L and chromium at 6.3 ug/L. No other parameters reported above the sample detection limit.
This incident should qualify for closure with no land use restrictions.
Hopefully, an easy review on your part. The owner is trying to complete a real estate deal so your
speedy review would be much appreciated. Please call me with any questions.
Do you need a hard copy?
