Hi Trudy
Attached is the UST-61 form for a release from an UST at the above property. Also attached is Cedar Rock's inspection
report and a figure showing the location of the inactive water supply well located approximately 110 feet from the
release area. The figure also shows the location of an active aboveground storage tank which is in the early stages of
leaking (see inspection report). I anticipate that the onsite well will be abandoned which should allow a Low Risk
classification for the release. If you require more information please let me know.
Thanks

Reference: Inspection of an underground storage tank (UST) located at 4429 Woodwind
Street, Charlotte, North Carolina
Cedar Rock Project # 292822590
Dear Mr. McManimen:
Cedar Rock Environmental, P. C. (Cedar Rock) performed a site inspection on May 9, 2020 at the
above referenced location. The purpose of the inspection was to determine if the UST formerly
used for storing heating had leaked causing significant contamination of the underlying soils. It is
our understanding the residence was built in 1968 which is most likely when the UST was installed.
An inactive UST was observed to be located parallel to and centered approximately 10.0 feet off
the western foundation wall of the house and about 6.5 feet south of the northwestern foundation
corner of the house. Neither the fill pipe nor vent pipes of the UST were observed. The depth to
the top of the UST is approximately 22 inches below land surface (bls). The UST has a length of
about 126 inches with an estimated diameter of approximately 48 inches and an estimated capacity
of about 1,000 gallons. The contents of the UST could not be determined as there was no access
to the tank's interior, however, based on sounding with a probing rod, the tank appears to be full.
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. The two copper fuel delivery/return lines belonging the UST were reported to
have been removed from the crawlspace by the owner. No petroleum odor or staining was
observed in the crawlspace.
An active above ground storage tank (AST) was also observed to be located along the northern
wall of the house. The AST was supported off the ground, was measured to contain approximately
134 gallons of fluid, and had a single copper fuel delivery line extending from the bottom of the
AST and going into the foundation wall where it was connected to the furnace in the crawlspace.
Some red oil was observed dripping from the bottom of the AST indicating the AST is in the early
stages of leaking.
Once the orientation of the UST was determined, a soil boring was performed at the northern end
of the UST using a 3.25-inch diameter stainless steel hand auger. The soil boring was advanced
to a depth of approximately 7.0 feet bls, about 1.2 feet below the bottom of the UST. A strong
petroleum odor and local discoloration was observed in the soils from a depth of approximately
4.0 to 7.0 feet bls suggesting significant leakage from the UST has occurred. The native soils

Mr. Mike McManimen

underlying the UST consist of a reddish orange sandy silt.
An inactive onsite water supply well is located within 150 feet of the petroleum release. For this
reason, 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. Although the petroleum release does not appear to pose a health risk, 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. Cedar Rock will submit a UST-61 form to satisfy the State's notification requirement for
the release upon your request.
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 143B- 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 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 the
inactive water supply well within 150 feet of the release is properly abandoned. 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
and abandoning the inactive supply well 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 the UST unless the property is reclassified to "Low Risk". Additionally, 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 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
all contaminated soil exceeding applicable standards. Scenario Two requires reclassifying the
property to "Low Risk" by abandoning the existing supply well within 150 feet of the release,
filing an NRP, and performing the Public Notification task.
Attempting to remove the UST and associated contaminated soils is costly, would be disruptive to
the property, and may not result in a clean closure. For these reasons, we do not recommend the

Mr. Mike McManimen

removal of the UST and associated contaminated soils. Instead, we recommend properly
abandoning the onsite supply well to lower the risk classification to "Low Risk" followed by
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 $3,800.00 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 abandoning the onsite water
supply well.
We also recommend taking the AST out of service and removing it to prevent further leakage.
Cedar Rock can remove the AST and contents for a charge of $500.00 plus $1.25 per gallon of
recovered fluids, if performed contemporaneous with other work.
If the site remains classified as High Risk, the State will require the removal of the UST and
associated contaminated soils. If required, Cedar Rock can remove the UST including 15 tons of
contaminated soil for a charge of $8,700.00 plus $1.25 per gallon of recovered fluids. Tonnage
in excess of 15 tons will be an added charge at the rate of $135.00 per ton. Based on the observed
soil contamination, it is estimated that at least 20 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 9 (February 1, 2019), 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 beyond 17 feet bls), the State will still require abandonment of
the water supply well, filing an NRP and performing Public Notification before issuing an NFA
letter.
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.
