Tetraethylead and tetramethylead are received by marine and rail transport vessels, unloaded and blended into motor fuel antiknock compounds in the TEL Area, and shipped from the plant via marine transport, rail and motor vehicles. Lead Is also routinely used in some solders In various applications throughout the plant. currently, lithium compounds are present In certain greases used on the plant in numerous applications and In the quality control laboratory. Lithium bromide solution will be used in a future refrigeration system to be installed in the Acrylonitrile Area. Received in railroad tank cards, used in TEL Area as an ingredient in lead alkyl antiknock compounds. (USHA has proposed to regulate EDB as a carcinogen and as a repro ductive hazard; proposal under review.) 11/5/79 Reissued: 12/6/83 (13.11) DUP 0501043 X)\J 001170
