March 7, 1952 Mr. L. R. Fleck F.thyl Corporation 100 Park Avenue i:ev York City 17 De ar 7an: Disposal of Sediment from Cleaning of lanks Containing Leaded Stocks In response to your letter of March '4 on the subject, indicated above, I can make little further contribution to our thinking of the pas-t several years. It seems apparent to me that sludge can be disposed of in a variety of ways under suitable circum stances - i.e. buried, dumped at sea, dumped into svamps or other similar waste places that are unlikely to. be entered or made use of without suitable precautions, (such as our ravine at Baton t Rouge, Du Font's swamp at Deepwater). When the quantitites are small the problem is relatively easy. Then perhaps chemical treatment could be used. The residue from the large tanks is the serious problem, and I fail to see what can be done, ether than what is being done about these cases, except at very considerable expense. It is all very veil to suggest "chemical treatment, combustion and dilution" but how? I'm willing to hear suggestions from any source, but. I have nothing to offer as a substitute for what is now being done. Who ever may wish to try something else should be encouraged and cooperated with. Sincerely yours, BAS ef Robert A. Kehoe, M.

In view of the report that the lead compounds in the sediment do not disperse over indefinite periods of time, it was suggested that: (1) the question of dispersal of lead compounds in sediment buried under the earth be developed; and (2) if the report is correct, investigate other methods for disposing of the sediments to render them harmless. These might be: (a) Chemical treatment (b) Combustion (c) Dilution (d) Other Please advise us as promptly as possible of the results of your investigation and of any recommendations in connection with the oroblem.
