Reference: Inspection of an underground storage tank (UST) located at 431 Canyon Trail,
Charlotte, North Carolina
Cedar Rock Project # 283722590
Dear Ms. Gaffney:
Cedar Rock Environmental, P. C. (Cedar Rock) performed a site inspection on November 26, 2019 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 1964 which is most likely when the UST was installed.
An inactive UST was observed to be located parallel to and centered approximately 7.0 feet off the southern
foundation wall and centered about 12.5 feet east of the northwestern 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 21
inches below land surface (bls). The UST has a length of about 69 inches with a diameter of approximately
48 inches and a capacity of about 540 gallons. The UST was measured to contain approximately 277
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 in the crawlspace to be cut and
crimped near the foundation wall adjacent to the UST. No petroleum odors or stains were observed in the
crawlspace.
Once the orientation of the UST was determined, a soil boring was performed at the western end of the
UST using a 3.25-inch diameter stainless steel hand auger. The soil boring was advanced to a depth of
approximately 7.1 feet bls, about 1.4 feet below the bottom of the UST. A moderate to strong
petroleum odor was observed in the soils from a depth of approximately 5.5 to 7.1 feet bls suggesting
significant leakage from the UST has occurred. The soils were not discolored. The native soils underlying
the UST consist of a light orange brown sandy silt.
The property is currently serviced by a municipal water supply. No water supply wells were observed
within 150 feet of the petroleum release. For this reason, the property should be classified as "Low Risk"
by the State.
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 your
request, 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 143B-279.11 (d). The NRP will
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. Once classified as "Low Risk" and the approval of an NRP, the DEQ will issue a "Conditional"
Notice of No Further Action (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 performing Public Notification
would not be required if all soil contamination exceeding applicable standards has been removed.
The State currently will not require any initial abatement or remedial action regarding the release of heating
oil from a UST on a "Low Risk" property. However, 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 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.
Currently, the presence of the soil contamination does not appear to pose any known health risk. 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 recommend the in -place 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, 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 $3,200.00 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.
Included with this report is our invoice. 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,
W_�`/ fVcensed

Trudy,
I have attached the signed NRPs and added the word Mecklenburg in the specified blank
as per your request. I have also attached a copy of our inspection report for each of these
sites which states that no wells were observed within 150 feet of the release and that both
sites should be classified as Low Risk. The reports are both signed and stamped by a
licensed geologist.

Good Afternoon Josiah & Bob,
Ron is out sick today. I do not know if he will be in the office tomorrow. The NRPs need to
have Mecklenburg added in the following section and be signed by Bob or the RP/Property
owner before UST review.
Any map or plat required by DEQ has been/shall be recorded at the Register
of
(name of county)
Deeds' office Book , Page , and has been/shall be incorporated into the Notice by this
reference.
I received the UST-61s for both sites by email. I have not been sent receptor information that
has been signed and sealed by a licensed geologist or professional engineer. These sites will
have unknown risk classifications until this information has been received or until I have time
to visit each site to gather receptor information. Keep in mind that each UST Project manager
is allowed 2 hours per week for noncommercial work.
