Document Description
In preparation for the construction of replacement school at the Site, DTSC is considering approval of a RAW in order to address the removal of lead from five excavation areas (see Figure 1). The excavated soil will be stored in roll-off bins at the Site, sampled, classified, profiled, manifested, and transported and disposed of appropriately as hazardous or non-hazardous waste. If disposal of hazardous soils is needed, those soils will be transported to a Class I landfill. If disposal of non-hazardous soils is needed, those soils may be transported to a Class II landfill or to a Class III landfill to be recycled for alternate daily cover.
