Solids .4500 <br /> ■ Vanadium 0.5 <br /> The LEA Clean Soil Levels for the fust seven metals (cadmium through zinc) are <br /> currently contained in the Monitoring and Reporting Program (MRP),which is part of the <br /> Waste Discharge Requirements (WDR) for the landfill. The LEA Clean Soil Levels for <br /> the remaining constituents are not part of the landfill's WDR, but are contained in a <br /> guidance document issued by the RWQCB. <br /> The RWQCB has indicated that they intend to revise the MRP to incorporate designated <br /> levels for constituents not currently included in that document. If the RWQCB <br /> establishes lower Designated levels (than those shown above) for any of the above <br /> inorganics, then the LEA Clean Soil Levels for those inorganics will drop to match the <br /> new designated levels. If the RWQCB establishes higher designated levels (than those <br /> shown above) for any of the above inorganics, then the LEA Clean Soil Levels for those <br /> inorganics will remain at the levels shown above. That is, the LEA Clean Soil Levels for <br /> inorganics may go lower to match RWQCB action, but may never go any higher <br /> regardless of any RWQCB action. This is because the LEA Clean Soil Levels for <br /> Inorganics, as stated above, are related purely to the SWFP tonnage cap not water quality. <br /> If(1) Forward Landfill personnel wish to classify a particular project or event job as <br /> Clean Soil, and (2) the soil is potentially contaminated with one, or more, of the above <br /> inorganics, it will be analyzed fust for total levels of the inorganics suspected to be <br /> .present. In the event that total concentrations are,.less than ten times the LEA Clean <br /> Soil Levels then the material will be classified as Clean Soil and not counted towards the <br /> daily and weekly tonnage caps in the SWFP. <br /> 3 <br />
