In October 1995, Raney Geotechnical performed an Environmental Site Assessment. The property was occupied by Hart Trucking,a truck rental and leasing company that utilized Building F for truck repair, and Innovative Steel Systems, which manufactures steel framed building structures in Buildings D and E. This report identified the following potential environmental concerns at the site: • The drain inlet to the clarifier was blocked with a black oily sludge; • The possibility of a release beneath the lined truck wash evaporation pond; • A stockpile of sand blast grit on the southeasterly portion of the property potentially containing elevated heavy metals concentrations; • Spray painting and waste storage areas in several locations on the site, including on bare ground; and, • A small oil spill within the southeast corner of Building C. Based on these findings, Raney Geotechnical recommended disposal of the material in the clarifier, obtaining an appropriate permit for the clarifier, and further investigation around the clarifier and beneath the truck wash evaporation pond. To the best of our knowledge, a permit has not been obtained. Similar findings were reported by Advanced GeoEnvironmental in their December 1-996 Report Review and Site Reconnaissance. The integrity of the truck wash evaporation pond liner appeared to be suspect due to vegetation observed growing through the liner in several areas. The clarifier was completely full with a dark liquid with a strong hydrocarbon odor. Dried paint covered the asphalt near two paint spray-booths located near the repair shop. Review of correspondence indicated that 276 drums of hazardous waste were transported off-site for disposal and recycling. In August 1997,Advanced GeoEnvironmental performed a soil investigation at the site. Six shallow soil samples were collected from the storm water retention pond on the eastern edge of the site and analyzed for total recoverable petroleum hydrocarbons by EPA Method 418.1. Eight soil probe borings were advanced to evaluate soil conditions adjacent to the three-stage clarifier and the evaporative pond. Soil samples were analyzed for total petroleum hydrocarbons quantified as gasoline and diesel (TPH-gasoline and TPH-diesel by EPA Method 8015M; benzene, toluene, ethylbenzene and xylenes (BTEX)by EPA Method 8020; and volatile organic compounds(VOCs) by EPA Method 8010. One of the samples was also analyzed for oxygenated fuel additives. The results of the investigation were as follows: R:\MN\98JCM.013 8 DAMES&MOORE
