detect for kerosene and motor oil, but did report varying g in amounts of diesel; TKIN 14' p 1100 ppm, TKIS@ 14' 2300 ppm, TK2N@ 14' 120 ppm, TK2S@ 14' 240 ppm, P1@5' 2700 ppm, P2@3' 140 ppm and composite of SP1, 2, 3, and 4 had 900 ppm. Results of the BTEX analyses reported 44 ppb (.044 ppm) total Xylenes in TKIN. Sample TKIS reported 48 ppb (.048 ppm) Toluene, 330 ppb (.330 ppm) Ethyl Benzene, and 920 ppb (.920 ppm) total Xylenes. Sample P1@5' contained 34 ppb (.034 ppm) Toluene, 470 ppb (.470 ppm) Ethyl Benzene, and 510 ppb (.510 ppm) total Xylenes. Soil samples TK2N@ 14', TK2S@ 14', and P2@ 3' were reported as non detect for BETX. A composite of samples SP1, 2, 3, and 4 reported 13 ppb (.013 ppm) of total Xylenes. The laboratory results are shown on TABLE 1. While minor diesel contamination was found in the western portion of the tank excavation pit, the major contamination of TPH-Diesel and L� BETX constituents were in the eastern portion of the excavation and under the piping. The final destination of the removed storage tanks was Schnitzer Steel Products at 12000 Folsom Boulevard, Rancho Cordova, CA. The rinsate was hauled by Nor-Cal Waste Oil Haulers to Refineries Service at 13331 N. Highway 33, Patterson, CA. The manifest and ttracking records are included in EXHIBIT A. OVER EXCAVATION & SAMPLING 519-5110194 C As a result of the above reported contamination, Jim Thorpe Oil, Inc. submitted a work plan to the SJPHS/EHD for over excavation and re-sampling, dated April 6, 1994, EXHIBIT B. Wm. J. Hunter & Associates was contracted to do the soil sampling and supervise the over excavating. Mr. Steve Sasson, from the SJHS/EHD was notified that the work would commence May 9, 1994. On May 9 and 10, the original excavation was over excavated an additional five (5) feet to the north, fourteen (14) feet to the south, and nine (9) feet to the east. The entire excavation was cleaned out of soil and various fill material consisting primarily of demolished building and construction materials to a depth of fourteen (14) feet. At this depth a layer of solid concrete was encountered which made further digging very difficult. This layered concrete material probably resulted from the area being used as a dump and wash pit for the ready-mix trucks. The product piping line was trenched an additional eight (8) feet long, by eight (8) feet wide, and nine (9) feet deep. Refer to PLATES VII & VIII for diagrams of the excavation. On May 10, 1394, at the direction of Mr. Sasson, soil samples were taken from the base � and sidewalls of the excavation, PLATE IX. Sample collection and packaging was done by Charles Fry, a registered geologist from Wm. J. Hunter & Associates. A total of nine (9) soil samples were collected for analyses of TPH-Diesel and BETX by a state certified laboratory. The samples were taken from the bucket of a;backhoe, put in brass tubes, end of the tube were covered with teflon and plastic caps were placed over the ends, securely fi �`' 4 I
