RE: Underground Storage Tank (UST) Closure Assessment Report
431 Canyon Trail, Charlotte, North Carolina
Cedar Rock Project Number 283722590
Dear Ms. Gaffney:
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 431 Canyon Trail in
Charlotte, North Carolina. The UST abandonment was performed on January 8, 2020. Included
in this report are project documents consisting of a laboratory report and chain -of -custody form, 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 a site inspection performed on November
26, 2019. The release was reported to the Department of Environmental Quality (DEQ) using a
UST-61 form on January 2, 2020. 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,
Robert A. Payne, L.G.
President

1.0 INTRODUCTION
Cedar Rock Environmental, P.C. (Cedar Rock) was contacted by Ms. Jeanne Gaffney of Charlotte,
North Carolina to abandon in -place an underground storage tank (UST) located at 431 Canyon
Trail in Charlotte, North Carolina. The UST was first inspected on November 26, 2019. 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.
On January 8, 2020, a soil sample (CR-1) was collected at a depth of 7.0 feet from the base of a
soil boring advanced at a location midway along the UST and approximately 1 foot onto the
neighboring property. The sample location is shown on the accompanying Site Map figure. The
sample was submitted for laboratory analysis using EPA Method 3550 and EPA Method 5030 for
High and Low Boiling Point Total Petroleum Hydrocarbons (TPH) respectively. No TPH were
detected in the sample by either method suggesting leakage from the UST has not migrated onto
the adjacent property. A copy of the laboratory report and chain -of -custody form are included in
Appendix A.
2.0 PROJECT
The in -place abandonment of the UST was performed on January 8, 2020. The abandonment
consisted of the hand excavation of the soils overlying the western 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.
Residual oil in the fuel lines was also removed by vacuum. Approximately 307 gallons of fluid
and sludge (including rinsate) were removed from the UST. The fluid disposal manifest for the
tank contents is included in Appendix B.
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 C - Photographic Documentation).

Good Morning Bob,
Was the home heating oil UST on the Norma Burton Property located at 431 Canyon Trail, Charlotte (Incident
#40971) abandoned in place (drained and filled)? Was Carin Kromm able to sign the Notice of Residual
Petroleum for this site yesterday for filing with the Mecklenburg County Register of deeds?
Thanks,
