Quik Stop Station No. 039 February 17, 1999 Stockton, California Tank Closure Report at a concentration of 14,800 ppm. Only low levels of BTEX and MTBE were reported at (1.0 ppm toluene, 0.018 ppm xylenes, and 0.18 ppm MTBE). Excavated Soil: Analytical results of soil samples collected from the excavated soil stockpiles indicated TPHg (60 to 63 ppm), BTEX (0.044 to 0.069 ppm toluene, 0.025 to 0.16 ppm ethylbenzene, and 0.74 to 1.6 ppm xylenes), MTBE (0.14 to 0.65 ppm), and lead (0:64 and 0.65 ppm). Replacement UST Excavation Soil: Analytical results of soil samples collected from the excavated soil used to backfill the former UST excavation indicated no detectable concentrations of TPHg, BTEX, or MTBE. Soil Disposal On November 21 and 25, and December 4, 1998, approximately 672 tons of soil were transported under Non -Hazardous Waste Manifests by Den Beste Transportation of Windsor, California to the Forward Landfill facility in Manteca, California for bioremediation and recycling. Copies of the Non -Hazardous Waste Manifests are included in Attachment B.
