Pollard Street Arlington, VA 22207 CEDAR ROCK ENVIRONMENTAL, P.C. 107 Pioneer Trail Graham, NC 27253 (336) 684-2734 RE: Underground Storage Tank (UST) Closure Assessment Report 421 Rensselaer Avenue, Charlotte, North Carolina Cedar Rock Project Number 366622590 Dear Ms. Schwartz: 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 421 Rensselaer Avenue in Charlotte, North Carolina. The UST abandonment was performed on June 14, 2023. 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 June 7, 2023. The release was reported to the Department of Environmental Quality (DEQ) using a UST- 61 form on June 7, 2023. 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 filed the NRP on June 8, 2023. The DEQ should 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 336-684-2734. Thank you for your consideration of Cedar Rock to provide you with this service. Sincerely, w�ct Robert A. Payne, L G.

Payne, L.G Geologist ii 1.0 INTRODUCTION Cedar Rock Environmental, P.C. (Cedar Rock) was contacted by Ms. Cynthia Schwartz of Arlington, Virginia to abandon in -place an underground storage tank (UST) located at 421 Rensselaer Avenue in Charlotte, North Carolina. The UST was first inspected on June 7, 2023. An inactive UST was observed to be located as shown in the Site Map. Both the fill and vent pipes of the UST were observed to be intact, however, the vent pipe was missing its cap. The depth to the top of the UST is approximately 20 inches below land surface (bls). The UST has a length of about 92 inches with a diameter of approximately 41.25 inches and a capacity of about 560 gallons. The UST was observed to be dry containing no fluids. White flagging was installed to mark the 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 copper fuel delivery/return lines, petroleum odors or stains were observed in the basement/crawlspace, however, the crawlspace had plastic on the floor. Once the orientation of the UST was determined, a soil boring was performed at the northeastern end of the UST using a 3.25-inch diameter stainless steel hand auger. The soil boring was advanced to a depth of approximately 5.5 feet bls, about 0.4 feet below the bottom of the UST. A strong petroleum odor and discoloration was observed in the soils from a depth of approximately 4.5 to 5.5 feet bls suggesting significant leakage from the UST has occurred. The native soils underlying the UST consist of an orange, brown sandy silt. The property is currently serviced by a municipal water supply. 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. 2.0 PROJECT The in -place abandonment of the UST was performed on June 14, 2023. The abandonment consisted of the hand excavation of the soils overlying the northeastern 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. Vacuum was applied to the fuel lines in an attempt to remove any residual oil in the lines. Approximately 40 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). 1 FIGURE SITE MAP 1 inch = 10 feet PROJECT: Revocable Trust Property CEDAR ROCK INCIDENT#: 49046 ENVIRONMENTAL, P.
