Appendix A AGE-NC No. 04-1168 Page 3 of 5 samples were analyzed for petroleum hydrocarbon products.The following target analytes were detected: • TPH-g was detected in soil samples collected from borings B1 and B2 at a maximum concentration of 500 milligrams per kilogram (mg/kg) in boring B1 at 25 feet bsg. • Toluene, ethylbenzene and xylenes were detected in borings 131 and B2 at maximum concentrations of 0.017 mg/kg toluene (132-45), 0.017 mg/kg ethylbenzene (132-45) and 6.3 mg/kg xylenes (132-35). • EDB was detected in one soil sample at a concentration of 0.045 mg/kg (132-35). No other target analytes were detected at or above laboratory detection limits in any of the samples analyzed. On 04 August 2004, AGE published Limited Site Investigation Report which reported all site activities, findings, and recommendations for an investigative work plan. AGE received an EHD directive letter, dated 31 August 2004, notifying the primary responsible party that the site was added to the EHD local oversight program and that a certified professional geologist must be reviewing all reports. AGE received an EHD directive letter, dated 08 January 2005, requiring the submission of an investigative work plan. On 15 March 2005,AGE published Monitoring Well Installation Work Plan which reported all purposed investigative activities, installations, and findings. AGE received an EHD directive letter, dated 05 April 2005, approving the submitted investigative work plan. On 31 May 2005, AGE published a letter, Monitoring Well Installation,which request a 60 day extension for all purposed investigative activities and installations. AGE received an EHD directive letter, dated 08 July 2005, approving the request for a 60 day extension . On 20 and 21 July 2005, three soil borings were advanced at the site for collection of soil samples and installation of three groundwater monitoring wells(MW-1 through MW-3).The monitoring wells were developed on 25 July 2005, and surveyed on 04 August 2005. Samples were collected from the borings at discrete five-foot intervals. A total of ten soil samples were analyzed for petroleum hydrocarbon products.The following target analytes were detected: • TPH-g was detected in soil samples collected from borings MW 1 and MW2 at concentrations of 1.5 mg/kg (MW1 at 35 feet bsg) and 1.0 mg/kg (MW2 at 50 feet Advanced Geo En%ironmental
