/ June 15, 1937 Hr. J. C. Taylor Ethyl Gasoline Corporation Chrysler Building New York, New York . Attention Mr. 0. B. Lewi3 Dear Hr.. Lewis: The tabulation below covers the results of analyses on the sanples of sludge from the Keystone Pipe Line Company sent to us by Ellis 0. Jone3. * (1) Pipe Line Sludge from Araste Pile Boot, Pennsylvania 1.35$ lead (2) Fresh Sludge Sample Boot, Pennsylvania 1.5*$ lead (3) Pipe Line Sludge from V/aste Pile Kontallo, Pennsylvania 0.34$ lead (*0 Fresh Sludge from Sediment Trap Montello, Pennsylvania 0.43$ lead . ^ The amounts of organic lead in all of the samples were leSsT than 0.0023$. The amounts of lead in all of these samples were less than amounts found in many samples of sludge and scale, but until we have more information on the behavior of small percentages of lead in mixture v/ith iron rust, I would recommend that precautions similar to those in cleaning tanks be taken when the sludge traps are cleaned. Furthermore, material that has been removed from the lines and traps should be buried. ' Very truly yours, WFM :vr 0022612 Willard F. Machie, M. D.
