analytical laboratory results of samples collected during the tank removal were included in Appendix A of the Work Plan (B&R, 1998). 2.1 SITE DESCRIPTION The site is located in the northwest portion of the Port of Stockton complex and is identified by PHS/EHD as "Site Code 1282." Figure 2 shows that the site is between warehouses A and G, just southwest of the intersections of Port Roads B and 2. The site had a 600-gallon steel tank(PHS/EHD ID #39-1282-03), which, according to the "Application for Permit to Close," contained unleaded gasoline. A dispenser was located a few feet southwest of the tank. No information is available as to the age of the tank. The tank and associated piping were removed on April 28, 1993 by Jim Thorpe Oil, Inc., under permit from PHS/EHD. The PHS/EHD inspection report indicated that the tank was in "good" condition, with no visible holes and a small amount of corrosion. Approximately 5 yards of soil were excavated with the tank to a depth of about 5 feet below ground surface (bgs). Excavated soils were stockpiled just north of the excavation. Soil samples were collected by GeoAnalytical Laboratories from two locations in the stockpile (which were composited for analysis) and one sample was collected from the backhoe bucket, which removed soil from beneath the center of the tank excavation at a depth of about 8 feet bgs. No groundwater was encountered during excavation or sampling. Soils beneath the tank were reported by PHS/EHD to be "clay loam" and contained "odor and discoloration." 2.2 SUMMARY OF PREVIOUS SITE CHARACTERIZATION WORK V Soil samples collected from beneath the tank and the composite soil sample from the stockpile were submitted to GeoAnalytical Laboratories for analysis of total petroleum hydrocarbons as gasoline (TPHg) by EPA method 5030; benzene, toluene, ethyl benzene, and total xylenes (BTEX) by EPA method 8020; total lead by EPA method 7420; and ethylene dibromide (EDB) r by the LUFT method. Analytical results (Table 1) indicated low levels of PHCs detected in both the stockpile and backhoe bucket samples, with no benzene or EDB detected in either sample, and only 28 mg/kg TPHg detected in the sample from beneath the tank. 3.0 SUMMARY OF ACTMTIES Drilling and sampling services were performed by Fisch Environmental Exploration Services (Fisch) of Valley Springs California, a C-57 licensed drilling contractor retained by B&R. 2 96117W4VR"SIS1US7WV.M
