Reference: Inspection of an underground storage tank (UST) located at 6708 Kemp
Street, Charlotte, North Carolina
Cedar Rock Project # 267522590
Dear Mr. Murphy:
Cedar Rock Environmental, P. C. (Cedar Rock) performed a site inspection on May 1, 2019 at the
above referenced location. The purpose of the inspection was to determine if the UST currently
used for storing heating oil had leaked causing significant contamination of the underlying soils.
It is our understanding the residence was built in 1963 which is most likely when the UST was
installed.
An active UST was observed to be located parallel to and centered approximately 4.7 feet off the
eastern foundation wall and about 2.0 feet south of the northeastern foundation corner of the house.
Both the fill and vent pipes of the UST were observed to be intact. The depth to the top of the
UST is approximately 18 inches below land surface (bls). The UST has a length of about 75 inches
with a diameter of approximately 44.5 inches and a capacity of about 500 gallons. The UST was
measured to contain approximately 56 gallons of fluid. White flagging was installed to mark the
ends of the UST. No other USTs on the property were discovered using a metal detector to survey
the outside perimeter of the residence where USTs are usually located. Two copper fuel
delivery/return lines were observed connected to the furnace in the basement. No petroleum odor
or staining was observed in the basement.
Once the orientation of the UST was determined, two soil borings were performed, one at each
end of the tank, using a 3.25-inch diameter stainless steel hand auger. Both soil borings were
advanced to a depth of approximately 7.0 feet bls, about 1.8 feet below the bottom of the UST.
The soils in the boring on the northern end of the UST exhibited a strong petroleum odor and
discoloration from a depth of approximately 4.5 to 6.0 feet bls, however, only a slight odor and no
discoloration was observed at the base of the boring. The soils in the boring on the southern end
of the UST exhibited a strong petroleum odor and discoloration from a depth of about 3.0 to 7.0
feet bls suggesting significant leakage from the UST has occurred. The native soils underlying the
UST consist of a grayish blue (discolored) sandy silt. Two soil samples, CR-1 and CR-2, were
collected at the base of the northern and southern borings, respectively, and will be submitted for
laboratory analysis, if required.
The property is currently serviced by a municipal water supply; however, an inactive water supply
well exists approximately 58 feet southeast from the petroleum release. Another water supply
well, which appears to be active, also exists on the neighboring property to the north 137 feet

upgradient from the release. Because these wells are within 150 feet of the release, the property
would be classified as "High Risk" by the State. No other wells were observed within 150 feet of
the release.
Based on the results of this investigation, significant contamination of the soils underlying the
UST has been confirmed. Current law (NCGS 143-215.85 (a) and (b)) requires that any
significant release of contamination be immediately reported to the North Carolina Department
of Environmental Quality (DEQ), Division of Waste Management, Mooresville Regional Office
(704-663-1699). According to State law, upon reporting the release, the current property
owner where a release is discovered is identified by the State as the "Responsible Party" for any
State required action relating to the UST leakage. Upon request by the property owner, Cedar
Rock can submit a UST-61 form to satisfy the State's notification requirement for the release.
Currently, the property cannot be legally conveyed until a Notice of Residual Petroleum (NRP)
is filed with the Mecklenburg County Register of Deeds office pursuant to NCGS 14313- 279.11
(d). The NRP would contain applicable land use restrictions to minimize the risk of exposure to
existing contamination. The land use restrictions prohibit any disturbance of site soils within a
specified radius of the estimated extent of soil contamination and prohibit the future operation or
installation of any water supply wells (excluding any active wells) within 150 feet of the
petroleum release. Further, the State will not issue a Notice of No Further Action (NFA) letter to
officially close out the release incident for "High Risk" properties such as this wherein soil or
groundwater contamination exceeding applicable standards remains onsite. The property would
be reclassified as "Low Risk" if all water supply wells within 150 feet of the release were
properly abandoned. If a clean water sample can be collected from the upgradient neighboring
well, the DEQ may not require the abandonment of that well. Once reclassified to "Low Risk",
the DEQ would issue a "Conditional" NFA letter to formally close out the release incident. The
"Conditional" provision in the NFA letter will be removed upon receiving a certified copy of the
filed NRP and the completion of Public Notification requirements. Filing the NRP, abandoning
the supply well(s), and collecting a water sample would not be required if all soil contamination
exceeding applicable standards is removed.
The State currently will not require any initial abatement or remedial action regarding the release
of heating oil from a UST unless there is an eminent health risk which at this time does not appear
to exist. However, once the presence of the UST and confirmed contaminated soil is disclosed to
other interested parties as required by State law, future buyers, home owner's insurance providers,
or lenders may require initial abatement and/or remedial actions relating to the UST prior to
making any commitments towards the property. In addition, there exists a potential for further
environmental impact to the property from continued leakage from the UST.
An NFA letter can be obtained in two different scenarios. Scenario One requires the removal of
all contaminated soil exceeding applicable standards. Scenario Two requires reclassifying the
property to "Low Risk" by abandoning (or possibly sampling the active well) the existing supply
wells within 150 feet of the release, filing an NRP, and performing the Public Notification task.
Cedar Rock can remove the UST including 15 tons of contaminated soil for a charge of
$7,600.00. Tonnage in excess of 15 tons will be an added charge at the rate of $130.00 per ton.
Based on the observed soil contamination, it is estimated that at least 40 tons of contaminated

soil will require removal. This would include appropriate environmental assessment, reporting,
and site restoration. All work performed would be in accordance with the recommended
practices and procedures outlined in the Underground Storage Tank Section Guidelines for Site
Checks, Tank Closure, and Initial Response and Abatement, Change 7 (July 7, 2017), published
by the North Carolina Department of Environmental Quality, Division of Waste Management,
UST Section. Please keep in mind that attempting to remove the UST and all contaminated soils
exceeding applicable standards carries some financial risk because if all the contamination
cannot be removed (i.e. if the contamination extends to beneath the rear stoop/steps and/or
foundation), the State will still require abandonment of the water supply well(s), filing an NRP
and performing Public Notification before issuing an NFA letter.
In the event the property can be reclassified to "Low Risk", another option would be
abandonment of the UST. The tank abandonment would consist of exposing a portion of the
UST by hand excavation, cutting a hole about two feet in diameter on the topside of the UST,
removing all tank and fuel line contents, pressure wash cleaning of the tank interior, and filling
the tank with an excavatable flowable fill cement slurry. A summary report signed by a licensed
geologist would be generated that would include photographs of each step of the abandonment
process, including a photograph of the interior of the UST to show the UST was properly
cleaned. Cedar Rock can provide this service for a charge of $3,000.00 plus $1.00 per gallon of
recovered fluids. Preparing and filing the NRP and performing the Public Notification
requirement will cost an additional $1,250.00. Cedar Rock would not be responsible for
properly abandoning the water supply well(s). If required, Cedar Rock can collect and submit a
water sample for laboratory analysis from the neighboring well for a charge of $700.00.
Attached is an invoice for the site inspection. We appreciate the opportunity to be of service to
you. If you have any questions regarding the content of this report, please call me at 336-376-
