Reference: Inspection of an underground storage tank (UST) located at 751 Lenhaven Street,
Concord, North Carolina
Cedar Rock Project # 296622590
Dear Mr. Gaskey:
Cedar Rock Environmental, P. C. (Cedar Rock) performed a site inspection on July 13, 2020 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 1952 which is most likely when the UST was installed.
An inactive UST was discovered to be located perpendicular to and centered approximately 10.3 feet off
the western foundation wall of the house and about 29.0 feet north of the southwestern 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 19 inches below land surface (bls). The UST has a length of about 92 inches with a diameter
of approximately 41.5 inches and a capacity of about 560 gallons. The UST was measured to contain
approximately 278 gallons of fluid. White flagging was used 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 basement
extending from the foundation wall adjacent to the UST about 20 feet to where they were crimped closed
near the former furnace location. No petroleum odor or staining was observed in the basement.
Once the orientation of the UST was determined, a soil boring was performed at the eastern end of the UST
using a 3.25-inch diameter stainless steel hand auger. The soil boring was advanced to a depth of
approximately 6.1 feet bls, about 1.1 feet below the bottom of the UST. A strong petroleum odor and
discoloration was observed in the soils from a depth of approximately 3.0 to 6.1 feet bls suggesting
significant leakage from the UST has occurred. The native soil underlying the UST consists of a grayish
brown micaceous sandy silt.
The property is currently serviced by a community water supply well located several hundred feet to the
south on a neighboring property. 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
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 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 Cabarrus County Register of Deeds office pursuant to NCGS 14313- 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 upon approval of the 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.

That sounds good, Trudy. I'll change it to the Raleigh office. Thank you for looking at these so quickly! I'll
send you copies of the filed NRPs once we get them signed and filed. Hope you're staying well.

Good Afternoon Josiah,
I reviewed the two draft NRPs (Joe Gaskey Property in Concord & Jill Harkey Property in Charlotte). You will need to
change Regional office to Raleigh on the UST review page if Mark will be approving the NRPs for filing. Everything looks
good. Scott Bullock approved the groundwater language in the Joe Gaskey Property. However, the UST Section would
not allow any water supply well to be installed downgradient of the plume of contamination if the owner were to
request installation of a water supply well in the future.
Have a great day,

Good morning Trudy,
Would you mind taking a look at these two NRPs? We'd like to take them with us on Wednesday for Mark to
sign them in Raleigh.
The NRP for the Joe Gaskey Property in Concord has an different version of the groundwater restriction. His
property is currently using a community well located several hundred feet away on another property, however,
Mr. Gaskey's property is large enough to where he could drill a well on his property greater than 150 feet from
the petroleum release if he ever needed to. Caroline in Asheville told us to use this wording on a similar
property up her way and I figured it might work well here, so please take a look at that. I have also attached
our abandonment report for this site.
The NRP for the Jill Harkey Property in Charlotte has to be filed a little prematurely. We are scheduled to
remove the UST and excavate contaminated soils tomorrow, however, they are scheduled to close on Friday
and we won't have lab results back by then to confirm if we cleaned up all of the contamination. Our clients
are not willing to reschedule the closing date and so the NRP needs to be on file by Friday. If our lab results
come back and show that we have in fact cleaned them up, I guess we will then have to file a cancelation of
NRP.
Thanks!
