jan-zi , zuuo s: iurm i4o.uzuo r. w o Soil Evaluation Process Soils proposed for delivery to Forward Landfill are subject to a specific review and evaluation process. The objective of this process is to determine(1) the suitability of the soil.for delivery to Forward Landfill (i.e., is the soil a hazardous waste that the landfill should not accept?) and(2), the proper reporting category for the soil (ix. Contaminated Soil or.Clean Soil)_ Typically, the generator is responsible for sampling and analyzing the soil for suspected contaminants and submitting the description of the soil (the profile) to Forward Landfill personnel for review and evaluation. Generators are required to fill out a Waste Profile Form that describes the origin of the material and what types of contaminants are anticipated to be present (ie. hydrocarbons, inorganics or organic compounds). This information is then reviewed by local and corporate waste approval personnel to ensure that the proper analytical tests have been run to adequately characterize the material. Once material is deemed acceptable at the facility, the generator is given manifests for each load of material that contain tracking codes so our system can track how much material carne from a given project and ensure that only approved materials are delivered to the facility. Soil Definitions As mentioned above, Forward Landfill personnel will use three criteria to define soils accepted at the landfill. These are: • LEA limits for Clean Soil Levels for Inorganics • Bay Area Air Quality Control Board(BAAQMD)Regulation 8,Rule 40 • Physical Characteristics We discuss each criterion in more detail below: LEA Clean Soil Levels for Inortanics The LEA Clean Soil Levels for Inorganics are listed below: LEA Clean Soil Levels (mo) • Cadmium 0.05 ® Chromium(VI) 0.5 .
