RE: Underground Storage Tank (UST) Closure Assessment Report
751 Lenhaven Street, Concord, North Carolina
Cedar Rock Project Number 296622590
Dear Mr. Gaskey:
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 751 Lenhaven Street in
Concord, North Carolina. The UST abandonment was performed on July 22, 2020. 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 a site inspection performed on July 13,
2020. The release was reported to the Department of Environmental Quality (DEQ) using a UST-
61 form on July 17, 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 meat 336-376-0394. Thank you for your consideration of Cedar Rock to provide you with
this service.
Sincerely,
Robert A. Payne,"L.G.

1.0 INTRODUCTION
Cedar Rock Environmental, P.C. (Cedar Rock) was contacted by Mr. Joe Gaskey of Concord,
North Carolina to abandon in -place an underground storage tank (UST) located at 751 Lenhaven
Street in Concord, North Carolina. The UST was first inspected on July 13, 2020. 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.
2.0 PROJECT
The in -place abandonment of the UST was performed on July 22, 2020. 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.
Residual oil in the fuel lines was also removed by vacuum. The fuel lines were removed from the
basement area. Approximately 308 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.
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).

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,
Trudy

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!
