RE: Underground Storage Tank (UST) Closure Assessment Report
3130 Fairfax Drive, Charlotte, North Carolina
Cedar Rock Project Number 327022590
Dear Ms. Wittebort:
Cedar Rock Environmental, P.C. (Cedar Rock) is pleased to submit this report describing activities
and results for the in -place abandonment of the onsite UST located at 3130 Fairfax Drive in
Charlotte, North Carolina. The UST abandonment was performed on September 3, 2021. Included
in this report are project documents consisting of a disposal manifest and photographic
documentation. This report should be kept with other documents pertaining to the residential
property.
Soil contamination was detected beneath the UST during abandonment activities on September 3,
2021. The release was reported to the Department of Environmental Quality (DEQ) using a UST-
61 form on September 3, 2021. Although the State no longer requires further assessment of the
contamination, the State does require the filing of a Notice of Residual Petroleum (NRP) prior to
conveying the property to another party. The NRP includes land use restrictions prohibiting any
disturbance of site soils within a specified radius of the estimated extent of soil contamination and
prohibits the use or installation of any water supply wells on the property. Cedar Rock is in the
process of filing the NRP. The DEQ will issue a Conditional Notice of No Further Action (NFA)
letter within the next few days. Upon receipt of proof that the local officials and adjacent property
owners have been notified of the release by receiving a copy of the Conditional NFA letter, and
that the NRP has been filed, the DEQ will reissue the NFA letter with no conditions to officially
close out the petroleum release incident.
Enclosed is an invoice for this work effort. If you have any questions, please do not hesitate to
contact me at 336-376-0394. Thank you for your consideration of Cedar Rock to provide you with
this service.
Sincerely,
W�Ct

1.0 INTRODUCTION
Cedar Rock Environmental, P.C. (Cedar Rock) was contacted by Ms. Suzanne Wittebort of
Charlotte, North Carolina to abandon in -place an underground storage tank (UST) located at 3130
Fairfax Drive in Charlotte, North Carolina. The UST was first inspected on August 23, 2021. An
inactive UST was observed to be located beneath a brick patio perpendicular to and centered
approximately 7.4 feet off the western foundation wall of the house and about 9.0 feet south of the
northern foundation wall of the house (see Site Map). Both the fill and vent pipe of the UST were
observed to be intact. The depth to the top of the UST is approximately 31 inches below land
surface (bls). The UST had an estimated length of about 74 inches with a diameter of
approximately 45 inches and an estimated capacity of about 550 gallons. The UST was measured
to contain approximately 284 gallons of fluid. White flagging was installed to mark both ends of
the UST (see Photo 1). 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. No petroleum odor
was observed in the crawlspace from the crawlspace entry.
Due to nearby unmarked utilities, no soil borings were performed during the initial site inspection
to inspect the soils beneath the tank to determine if the tank had leaked. Inspection of the soils
was deferred until after underground utilities were located.
2.0 PROJECT
The in -place abandonment of the UST was performed on September 3, 2021. The abandonment
consisted of the hand excavation of the soils overlying the eastern end of the UST to expose the
topside of the tank. A hole approximately 1.5 feet in diameter was then cut on the top of the UST
to allow for removal of the tank contents, cleaning and visual inspection of the UST interior, and
subsequent filling. The tank was pressure washed to remove all residual petroleum sludge. Large
corrosion holes were observed in the bottom of the UST. Residual oil in the fuel lines was also
removed by vacuum. The fuel lines were removed from the crawlspace. Approximately 400
gallons of fluid and sludge (including rinsate) were removed from the UST. The fluid disposal
manifest for the tank contents is included in Appendix A.
A soil boring was performed at the eastern end of the tank using a 1/2-inch diameter auger drill.
The soils underlying the UST were observed to be discolored and to have a strong petroleum odor
indicating that significant leakage from the UST has occurred.
After the interior of the UST was cleaned, the tank was then entirely filled with an excavatable
flowable fill cement slurry. Once filled, the exposed portion of the UST was then covered with
site soils (see Appendix B - Photographic Documentation).

Good evening, Trudy. I hope you had a good labor day weekend! Would you mind taking a look at the
attached NRP for approval? We will be meeting with Mark around lunch time tomorrow (Tuesday) and it
would be great if we could get this NRP signed then.
I have also attached our inspection report that states the site is Low Risk, our abandonment report, and the
UST-61 just so you have it all here. Please let me know if you have any questions.
