RE: Underground Storage Tank (UST) Closure Assessment Report
332 Spring Street SW, Concord, North Carolina
Cedar Rock Project Number 248222590
Dear Mr. Hill:
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 332 Spring Street SW in
Concord, North Carolina. The UST abandonment was performed on May 22, 2018. 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 May 14,
2018. The release was reported to the Department of Environmental Quality (DEQ) using a UST-
61 form on May 18, 2018. 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 that prohibit any
disturbance of site soils within a specified radius of the estimated extent of soil contamination, and
the use or installation of any water supply wells on the property. Cedar Rock filed the NRP on
May 22, 2018. 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, Z. G.

1.0 INTRODUCTION
Cedar Rock Environmental, P.C. (Cedar Rock) was contacted by Mr. John Hill of Lancaster, South
Carolina to abandon in -place an underground storage tank (UST) located at 332 Spring Street SW
in Concord, North Carolina. The UST was first inspected on May 14, 2018. An inactive UST was
discovered to be located parallel to and centered approximately 5.0 feet off the northwestern
foundation wall of the house and about 8.2 feet southwest of the northern foundation corner of the
house. Both the fill and vent pipes of the UST were observed to be intact with the vent pipe angled
over to the foundation wall. The depth to the top of the UST is approximately 31 inches below
land surface (bls). The UST has a length of about 77 inches with a diameter of approximately 45
inches and a capacity of about 550 gallons. The UST was measured to contain less than one gallon
of fluid. White flagging was installed to mark the ends of the UST. No other USTs were
discovered on the property using a metal detector to survey the outside perimeter of the residence
where USTs are usually located. Two cut and crimped copper fuel delivery/return lines were
observed in the basement extending from the foundation wall adjacent to the UST where they went
below ground and resurfaced at the former furnace location. No petroleum odors or staining were
observed in the basement.
Once the orientation of the UST was determined, two soil borings were performed, one at each
end of the UST, using a 3.25-inch diameter stainless steel hand auger. The soil boring at the
southwestern end of the UST was advanced to a depth of approximately 7.5 feet bls, about 1.2 feet
below the bottom of the UST. The soils from a depth of approximately 5.7 to 7.0 feet bls exhibited
a strong petroleum odor and were locally discolored. The soils at the base of the boring exhibited
a slight petroleum odor and were not discolored. The soil boring at the northeastern end of the
UST was advanced to a depth of about 8.0 feet bls, approximately 1.7 feet below the bottom of the
UST. The soils from a depth of approximately 7.0 to 8.0 feet bls exhibited a strong to moderate
petroleum odor and were locally discolored. The native soils underlying the UST consist of a light
orange brown silty micaceous sand (granitic). Two soil samples, CR-1 and CR-2, were collected
at the base of the southwestern and northeastern borings, respectively. Sample CR-2 was
submitted for laboratory analysis using EPA Method 3550 for Diesel Range Organics Total
Petroleum Hydrocarbons. The results of this analysis detected 532 ppm TPH which exceeds the
applicable TPH Action Limit of 100 ppm. 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 May 22, 2018. The abandonment
consisted of the hand excavation of the soils overlying the southwestern 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.
Approximately 30 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).

Trudy,
You can generate an incident number. Bob can be sent the conditional NFA letter and the final one once we
receive the public notice requirements. The site can then be closed out and the NFA information added to the
RUST database.
thanks
