Approximatel bic yards of <br /> soil and pea gravel were generated during excavation or 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 fuel hydrocarbons (ND to 23 ppm) , and very low concentrations of metals <br /> (apparently background :levels). Bioassay testing indicates the material is <br /> not hazardous or toxic. The operator has requested permission to redistribute <br /> the treated soil and 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 meat (916) 361-5731. <br /> THOMAS D.
