Reference: Inspection of an underground storage tank (UST) located at 8610 Douglas Drive,
Charlotte, North Carolina
Cedar Rock Project # 343522590
Dear Mr. Sayasith:
Cedar Rock Environmental, P. C. (Cedar Rock) performed a site inspection on April 29, 2022 at the above
referenced location. The purpose of the inspection was to determine if the UST previously used for storing
heating oil had leaked causing significant contamination of the underlying soils. It is our understanding the
residence was built in 1961 which is most likely when the UST was installed.
An inactive UST was observed to be located as shown in the Site Sketch. Both the fill and vent pipes of
the UST were observed to be intact. The depth to the top of the UST is approximately 17 inches below
land surface (bls). The UST has a length of about 92 inches with a diameter of approximately 40 inches
and a capacity of about 500 gallons. The UST was measured to contain approximately 356 gallons of fluid.
White flagging was installed to mark the ends of the UST (see Photo). No other USTs on the property were
discovered using a metal detector to survey along the outside perimeter of the house where USTs would
usually be located. Two copper fuel delivery/return lines were observed in the crawlspace to be cut and
crimped about one foot off the foundation wall adjacent to the UST. No petroleum odors or stains were
observed in the crawlspace from the entry.
Once the orientation of the UST was determined, a soil boring was performed at the western end of the tank
using a 3.25-inch diameter stainless steel hand auger. The boring was advanced to a depth of approximately
6.5 feet bls, about 1.75 feet below the bottom of the UST. A moderate to strong petroleum odor was
observed in the soils from a depth of approximately 5.0 to 6.5 feet bls suggesting significant leakage from
the UST has occurred. The native soils underlying the tank consist of a reddish orange sandy silt. One soil
sample, CR-1, was collected from the base of the boring and can be submitted for laboratory analysis, if
required.
The property is currently serviced by an active(?) water supply well located approximately 24 feet south of
the UST. Because this well is located within 150 feet of the petroleum release, the property would be
classified as "High Risk" by the State. No other water supply wells were observed within 150 feet of the
release. Municipal water appears to be available for hookup.
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
petroleum 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 will 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 on the
property excluding the existing well. 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 the onsite water supply well within 150 feet of the release were properly
abandoned. A new source of water would need to be established. Once reclassified to "Low Risk", an
NRP approved, and abatement of the petroleum release performed, 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 identified water supply well, connecting to a municipal
water supply, and completing Public Notification would not be required if all soil contamination exceeding
applicable standards is removed.
The State currently will require initial abatement or remedial action regarding the release of heating oil
from a UST on a "High Risk" property. Further, once the presence of the UST and confirmed contaminated
soil is disclosed to other interested parties as required by State law, future buyers, homeowner's insurance
providers, or lenders may also require initial abatement and/or remedial actions relating to the UST prior to
making any commitments towards the property. There also 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 the UST
and all associated contaminated soil exceeding applicable standards. Scenario Two requires reclassifying
the property to "Low Risk" by abandoning the water supply well (requires a certified well driller and the
submittal of a well abandonment record), connecting to a municipal water supply, filing an NRP,
performing the Public Notification task and abating the petroleum release (removing tank contents and
cleaning the tank interior).
Cedar Rock can remove the UST including up to 15 tons of contaminated soil for a charge of $13,000.00
plus 1.25 per gallon of recovered fluids. Tonnage in excess of 15 tons will be an added charge at the rate
of $125.00 per ton. 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 Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement, Change 11
(May 17, 2021), 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 deeper than our excavation equipment can reach), the State will
still require abandonment of any water supply wells within 150 feet of the release, filing an NRP and
performing Public Notification before issuing an NFA letter.
In the event the property is reclassified to "Low Risk" to allow for the abandonment of the tank, it 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 a structurally supportive yet 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 $3,500.00 plus $1.25 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 identified water
supply well within 150 feet of the release.
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 336-376-0394.
Sincerely,
Poe

Hi Trudy
UST-61 form for a release at the above property attached along with a copy of our inspection report. We removed the
UST today and excavated about 40 tons of soils. I believe we were able to remove all contamination. IAA report will
follow after analytical results are received.
