The <br /> purpose of the work was to accurately characterize the levels of volatile hydrocarbon <br /> constituents within cells 1 , 7, and 19 to determine if soil remediation was feasible. <br /> No sample results have been submitted to our office to date. Please advise our office <br /> by 10 January 1992 of the status of field work proposed in the workplan. <br /> In your 7 May 1991 Technical Report, you indicated that the City intended to use 11 ,000 <br /> cubic yards of this contaminated soil as roadbase at two road construction sites in <br /> Tracy, California. What is the status of this proposed action? Was all of the soil <br /> with Total Recoverable Hydrocarbons (TRH) below 1000 mg/kg planned to be used as <br /> roadbase? <br /> We are assuming that you still intend to utilize the cells as a land treatment <br /> facility. Therefore, we will formulate waste discharge requirements for a Class II <br /> land treatment facility. <br /> If you have any questions, please contact me at (916) 361-5737. <br /> +� J <br /> ROBERT A.
