Bennett Properties Page 2 In addition to the above, I have reviewed numerous SJLHD forms, memos, and logbook entries concerning SJLHD involvement with this site. These were also forwarded to us by SEU. BACKGROUND The property consists of eleven acres, comprising four assessor's parcels. It is bounded by South Main Street on the east, the Highway 120 Manteca Bypass on the south, open fields on the west, and houses on the north. The most recent commercial use of the property (1981 to 1987) was as a truck parking and routine maintenance area. From 1942 to 1984 , sections of the property were rented for a variety of uses. These included an auto repair shop (1964 to 1978) and a highway striping company. The site is generally flat. The surface soils are sandy and are not paved. A metal building with a concrete floor slab is located near the center of the property. The building will be removed prior to development of the property. A septic tank system associated with the metal building was constructed in 1976 and consists of a 1, 200 gallon tank and a filter bed lying approximately 80 feet west of the tank. No indications of other underground tanks were found in Dames and Moore's site screening. The Site Screening Report noted trash and debris on the site, but no hazardous material containers were seen in the debris piles. However, a "few" spots of dead vegetation and stained soil were found in the vicinity of the metal building. One of these spots exhibited an "oily" smell. Standing water immediately north of the building had an oily sheen. Dames and Moore concluded that it did not appear likely that a significant contamination problem exists at the site. They recommended sampling surface soils at the visibly affected areas. Such samples were taken and a composite was analyzed. The analysis revealed 21, 000 mg/kg TPH. Bennett Properties subsequently excavated about 120 cubic yards of visibly contaminated soils and stored the soils on tarps at the site. This activity was observed by a member of the Manteca Fire Department who complained to the SJLHD. Bennett Properties was told by SJLHD to cease all activities until a clean-up proposal was approved by SJLHD.
