FILENAME: 2916-Fig1-UST61.fc7 VERSION DATE: 5/18/20 SITE MAP FIGURE 1 Cedar Rock ENVIRONMENTAL April 30, 2020 Mr. Ivan Rodriguez 1230 Robinhood Circle Charlotte, NC 28227 CEDAR ROCK ENVIRONMENTAL, P.C. 107 Pioneer Trail Graham, NC 27253 (336) 376-0394 Reference: Inspection of an underground storage tank (UST) located at 1230 Robinhood Circle, Charlotte, North Carolina Cedar Rock Project # 291622590 Dear Mr. Rodriguez: Cedar Rock Environmental, P. C. (Cedar Rock) performed a site inspection on April 27, 2020 at the above referenced location. The purpose of the inspection was to determine if the UST previously used for storing heating oil had leaked causing significant contamination of the underlying soils. It is our understanding the residence was built in 1963 which is most likely when the UST was installed. An inactive UST was observed to be located parallel to and centered approximately 10.0 feet off the northern foundation wall and about 14.5 feet west of the northwestern foundation 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 13 inches below land surface (bls). The UST has a length of about 75 inches with a diameter of approximately 44.5 inches and a capacity of about 500 gallons. The UST was measured to contain approximately 256 gallons of fluid. White flagging was installed to mark the ends of the UST. No other USTs used for storing heating oil were discovered on the property 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 about 30 feet where they were cut and crimped at 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 western end of the tank using a 3.25-inch diameter stainless steel hand auger. The boring was advanced to a depth of approximately 6.0 feet bls, about 1.2 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 6.0 feet bls suggesting significant leakage from the UST has occurred. The native soils underlying the UST consist of a brownish blue -gray sandy silt. The property is currently serviced by a municipal water supply; however, a water supply well is located in the southwest corner of the garage within 150 feet of the petroleum release. Because this well is within 150 feet of the release, the property would be classified as "High Risk" by the State. The property could be classified as "Low Risk" if the well was properly abandoned. Based on the results of this investigation, significant contamination of the soils underlying the UST has been confirmed. Current law (NCGS 143-215.85 (a) and (b)) requires that any significant release of petroleum be immediately reported to the North Carolina Department of Environmental Quality (DEQ), Division of Waste Management, Mooresville Regional Office (704-663-1699). According to State law, upon reporting the release, the current property owner where a release is discovered is identified by the State as the "Responsible Party" for any State required action relating to the UST leakage. Upon your request, Cedar Rock will submit a UST-61 form to satisfy the State's notification requirement for the Mr. Ivan Rodriguez April 30, 2020 Page 2 release. Currently, the property cannot be legally conveyed until a Notice of Residual Petroleum (NRP) is filed with the Mecklenburg County Register of Deeds office pursuant to NCGS 143B- 279.11 (d). The NRP would contain applicable land use restrictions to minimize the risk of exposure to existing contamination. The land use restrictions prohibit any disturbance of site soils within a specified radius of the estimated extent of soil contamination and prohibit the future operation or installation of any water supply wells on the property. Further, the State will not issue a Notice of No Further Action (NFA) letter to officially close out the release incident for "High Risk" properties such as this wherein soil or groundwater contamination exceeding applicable standards remains onsite. The property would be reclassified as "Low Risk" if all water supply wells within 150 feet of the release were properly abandoned. Once reclassified to "Low Risk" and an NRP approved, the DEQ would issue a "Conditional" NFA letter to formally close out the release incident. The "Conditional" provision in the NFA letter will be removed upon receiving a certified copy of the filed NRP and the completion of Public Notification requirements. Filing the NRP and abandoning the onsite water supply well within 150 feet of the release would not be required if all soil contamination exceeding applicable standards is removed. The State currently will require initial abatement or remedial action regarding the release of heating oil from a UST on a "High Risk" property. Further, once the presence of the UST and confirmed contaminated soil is disclosed to other interested parties as required by State law, future buyers, homeowner's insurance providers, or lenders may also require initial abatement and/or remedial actions relating to the UST prior to making any commitments towards the property. There also exists a potential for further environmental impact to the property from continued leakage from the UST. An NFA letter can be obtained in two different scenarios. Scenario One requires the removal of the UST and all associated contaminated soil exceeding applicable standards. Scenario Two requires reclassifying the property to "Low Risk" by abandoning the inactive supply well within 150 feet of the release, filing an NRP, and performing the Public Notification task. Attempting to remove the UST and associated contaminated soils is costly, would be disruptive to the property, and may not result in a clean closure. For these reasons, we do not recommend the removal of the UST and associated contaminated soils. Instead, we recommend properly abandoning the onsite supply well to lower the risk classification to "Low Risk" followed by abandonment of the UST. The tank abandonment would consist of exposing a portion of the UST by hand excavation, cutting a hole about two feet in diameter on the topside of the UST, removing all tank and fuel line contents, pressure wash cleaning of the tank interior and filling the tank with an excavatable flowable fill cement slurry. A summary report signed by a licensed geologist would be generated that would include photographs of each step of the abandonment process, including a photograph of the interior of the UST to show the UST was properly cleaned. Cedar Rock can provide this service for a charge of $3,200.00 plus $1.25 per gallon of recovered fluids. Preparing and filing the NRP and performing the Public Notification requirement will cost an additional $1,250.00. Cedar Rock would not be responsible for abandoning the onsite water supply well. If the site remains classified as High Risk, the State will require the removal of the UST and associated contaminated soils. If required, Cedar Rock can remove the UST including 15 tons of contaminated soil for a charge of $8,500.00 plus $1.25 per gallon of recovered fluids. Tonnage in excess of 15 tons will be an added charge at the rate of $120.00 per ton. Based on the observed soil contamination, it is estimated that at least 20 tons of contaminated soil will require removal. This would include appropriate environmental assessment, reporting, and site restoration. All work performed would be in accordance with the recommended practices and procedures outlined in the Underground Storage Tank Section Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement, Change 9 (February 1, 2019), published by the North Carolina Department of Environmental Quality, Division of Waste Management, Mr. Ivan Rodriguez April 30, 2020 Page 3 UST Section. Please keep in mind that attempting to remove the UST and all contaminated soils exceeding applicable standards carries some financial risk because if all the contamination cannot be removed (i.e. if the contamination extends beyond 17 feet bls), the State will still require abandonment of the water supply well, filing an NRP and performing Public Notification before issuing an NFA letter. Attached is an invoice for the site inspection. We appreciate the opportunity to be of service to you. If you have any questions regarding the content of this report, please call me at 336-376-0394.
