Box 2009 <br /> Stockton CA 95201 <br /> SAFEWAY MEAT PACKING FACILITY, 1111 NAVY DRIVE, STOCKTON REDISTRIBUTION OF <br /> TREATED SOIL AND PEA GRAVEL <br /> We have reviewed the 28 November 1989 letter/report submitted key Western <br /> Geologic Resources , Inc. , for this site. Approximately 1200 cubic yards of <br /> soil and pea gravel were generated during excavation of former underground <br /> storage tanks. The excavated materials has been treated by aeration on-site. <br /> According to the report, the treated material now contains only low levels of <br /> total tuel hydrocarbons (NO to 23 ppm) , and very low concentrations of metals <br /> (apparently background )evels) . bioassay testing indicates the material 15 <br /> not hazardous or toxic. The operator has requested permission to redistribute <br /> the treated suil died pea gravel on-site. <br /> The primary concern with proposed redistribution of the treated soil is <br /> whether the hydrocarbon constituents have been effectively removed. Based on <br /> the information provided , the hydrocarbon Concentrations appear to have been <br /> reduced to levels which should not pose a significant threat to water quality. <br /> Therefore, we do not object to the proposed redistribution of this material <br /> If you have any questions, please call sne at (916) 361-5731. . <br /> WMAS 0.
