t40t Wilton Mootavon/ Arlington. Virginia 33309 7031934-9400 Center for Naval Analyses #n t/fihtlf *P tf\t Unh/truty of Aoc (NATEJ33-72 17 January 1972 Hr. Charles H. Sommer, President The MONSANTO Co. 600 North Lindberg Blvd. St. Louis 66, MO. Dear Mr. Sommer: I am not sure to which MONSANTO office this letter should be addressed and will appreciate you forwarding it to the proper office. The Center for Naval Analyses is working closely with the offices of the Chief of Naval Operations and the Secretary of the Navy in an effort to cle'an up the Navy's pollution problems. We are most directly concerned with the marine environment. It appears that one of the most serious threats to the marine environ ment is the class of chemicals known as polychlorinated biphenyls (PCB's). We do not at this time know which commands are using PCB's or how they are disposing of used PCB's, but we are making an effort to find out. we are finding it very difficult to trace PCB's through the purchasing arm of the Navy. Can you provide us any assistance? Specifically, can you advise us of any direct shipments of PCB's to particular agencies or commands in the Navy? Can you advise us as to par ticular products (preferably by type and manufacturer) in which we are likely to find PCB's that could present a disposal problem? We do, of course, know that PCB's are used in transformers, capacitors, heat trans fer systems, hydraulic systems, gas turbines, vacuum pumps, paints, lub ricants, adhesives, sealants, asphalt tile, printing inks, carbonless carbon paper, and plastics, but we are having some difficulty in identify- ihg the particular components and systems that present PCB disposal problems. - Any other information that you can provide on locating uses of PCB's In the Navy and proper disposal of PCB's will be appreciated.
