LLNL is also making a sweep of laboratory facilities to locate <br /> and remove additional unidentified containers. It is estimated that as many <br /> as another 400 small containers may be found during this sweep that will need <br /> to be handled and disposed of in the manner proposed in this letter. As it <br /> should be assumed that any of the unidentified containers could potentially <br /> contain reactive material , such as crystalleized picric acid, anyone <br /> attempting to open and sample the containers would do so at great risk. The <br /> option which appears to be the safest method of sampling these unknown wastes <br /> for disposal is outlined below and discussed in more detail in the attached <br /> Proposed Work Plan. <br /> The basic proposal is to remove containers of unknown wastes to a remote <br /> section of Site 300. At this location the containers would be carefully <br /> placed and crushed on a bed of absorbent material mixed with sand and lime. <br /> The containers would be crushed by using the bucket of a trackhoe. After <br /> crushing of containers is complete, the bedding material would be sampled and <br /> analysed to determine proper handling and disposal requirements. All of the <br /> bedding material including the underlying plastic sheeting would be packaged <br /> and disposed of at a permitted hazardous waste disposal facility. <br /> Since Site 300 is not currently permitted to handle or "treat" wastes in the <br /> manner described above, LLNL requests an emergency permit to allow this <br /> activity to occur in accordance with Section 66393(a) of the California <br /> Administrative Code. Crushing of containers will be a one time occurrence and <br /> all contaminated materials produced by the operation will be removed for <br /> proper off-site disposal . The work will be performed by a contractor <br /> experienced in this type of operation. The anticipated schedule for <br /> completion of the removal , crushing, sampling, and packaging operation is one <br /> An EgLia!OpportL"ty E,—r eW-L"vi-s tyol Ca6tomia-PO.Box 808 Lia more.Caibrrtia 94550-Taephor)e(415)422-1100-Twx 910-386-8339 UCLLL LWAP <br />
