I Site Location This report was prepared for Product Recovery Management and is the Underground Storage Tank (UST) Closure Assessment that was performed on December 30, 1997 at the former Hendrick Chevrolet facility located on East Market Street, Durham, Durham County, NC. The site is located along East Market Street, in a commercial area of Durham, NC. Figure I, Site Vicinity Map, illustrates the general site location on the USGS 7.5 minute series topographic map. Fib'llre 2 illustrates the Site Plan. Figure 3 illustrates the tanks orientation, soil sample locations. The Notification ofintent to Close is provided as Appendix A. 1.2 Facility Description The subject site formerly operated as a car dealership, and is owned by GWC properties located in Durham, NC. There have been no other known past releases at the facility, and the tanks were active. Appendix B provides the Site Investigation Report for Permanent Closure or Change in Service of UST. Figure 2 identifies the former site features, the utilities in the immediate area, and illustrates the location of the former UST's. 1 2,000 gallon capacity fiberglass UST, which reportedly stored used oil and I 6,000 gallon capacity fiberglass UST, which reportedly stored gasoline were removed from the property. The UST's were removed, stenciled and hauled off site by Charlie Miller Backhoe & Hauling, Inc., Youngsville, NC for disposal by the same. The UST Destruction and Disposal Certificate is provided as Appendix C. Table I provides a listing of Project Contacts. Table 2 is a summary of the UST information. A vehicular water well survey was conducted for private potable wells. 2.0 FIELD ACTIVITIES 2.1 UST System Removal Activities UST system removal activities were conducted on December 30, 1997. PRM was responsible for the UST excavation and major reconstruction activities for the site. A trackhoe was used for excavation and removal of the UST's. Groundwater was encountered during excavation activities for the used oil UST at a approximate depth of 3.0 feet Below Grade Level (BGL). Free product was observed in the used oil tank basin. Groundwater was not encountered during the gasoline UST removal. Bedrock was not encountered during excavation activities at any depth. The UST' s were buried approximately 2.0 feet BGL. Approximately 1522 gallons of groundwater and free product were pumped from the used oil excavation before removal of the tank. A & D environmental and Industrial Services, Inc. of High Point, NC pumped and disposed of the material. 2.2 Groundwater and Soil Sample Collection Two soil samples were collected from beneath the gasoline UST in accordance with NC Department of Environmental Management (NCDEM) guidelines and the Scope of Work for this project. A composite sample was taken from the soil stockpile from the used oil excavation. Backfill material appeared to consist of a medium sand. The soil samples were sealed in the appropriate laboratory provided containers and placed on ice. 3.0 LABORATORY ANALYSIS The collected soil samples collected during UST removal activities, were submitted to Paradigm Analytical Laboratories, Wilmington, NC. The soil samples beneath the gasoline tank were submitted for laboratory analysis Total Petroleum Hydrocarbons by EPA method 5030. Laboratory analysis of soil samples Tl- Fill and Tl-Sue showed less than 8 mg/kg and 11 mg/kg total petroleum hydrocarbons respectively. The composite soil sample taken from the stockpile removed from the used oil UST basin was taken and analyzed for volatiles by EPA method 8021, Oil and Grease by method 9071 and TCLP Metals. The analysis revealed Oil and Grease at 350 mg/kg,lead at 23.9 ug/I and below detection limits for the volatile compounds by EPA method 8021. The laboratory analytical results and Chain of Custody are included as Appendix D. Table 4 summarizes the reported soil constituents. 4.0 SUMMARY AND CONCLUSIONS The writer has completed the underground storage tank closure assessment of the subject property at the former Hendrick Chevrolet facility located in Durham, NC. Based on field activities, site observations, and subsequent laboratory analyses of the groundwater sample, the following is concluded: • Laboratory analysis of soil sample T-1 Sue indicated a TPH GRO level of 11 mg/kg. This level exceeds the NCDEM action level of 10 mg/kg. • Soil analysis of the used oil stockpile revealed an oil and grease level of 350 mg/kg. • A Light Non Aqueous Phase Liquid was present floating on the water table within the used oil tank pit. 5.0 LIMITATIONS This report is based on the collection of one groundwater sample and subsequent chemical analyses. The conclusions presented in this report are based only on the observation made during this investigation and on data provided by others. The report presents a description of the subsurface conditions observed at each excavation location during this investigation. Subsurface conditions may vary significantly with time, particularly with respect to groundwater elevations and quality. Conclusions and recommendations set forth herein are applicable only to the facts and conditions described at the time of this report. In performing its professional services, this writer uses that degree of care and skill exercised under similar circumstances by members of the environmental profession practicing at the same or similar locality under similar conditions. The standard of care shall be judged exclusively as of the time these services are rendered and not according to later standards. This writer makes no express or implied warranty beyond its conformance to this standard. This writer shall not be responsible for conditions or consequences arising from the relevant facts that were concealed, withheld or not fully disclosed for this report. This writer believes that all information contained in this report is factual, but no guarantee is made or implied.
