Hamlet i G. J. Geers J. W. Molloy A. E. Lelsy Recently there has been an outburst in the West Coast V Hf^ss about the toxic effects of Aroclors in San Francisco .V, Bay and other bodies of water. Aroclor appears to be similar 'V^ to DDT in that it 13 absorbed by fish and other aquatic fauna j ' : and accumulated in the tissue. Further concentration is said t to occur in birds or mammals feeding on the fish. There are n few details available and the reports could be exaggerated. However, sufficient publicity has been given to the problem "> to cause us some problems. V.'e, therefore, need a plan to combat its effect on this plant. Nr, No J__ What we propose is: t .. 1. Sample sewers, outfall, upstream and downstream river water and sludge from river and treatment plant, to evaluate the problem. (A method is presently being developed at South Second Street.) 2. Discontinue sewering spent Aroclors within the plant. 1* J. Carefully check operation for possible accidental losses to sev<er. a) Leaks in heat exchange systems. . 'V. \^ w V- b) Manufacturing operations. c) HC1 off-gas - drowning or scrubbing. We believe that the use of Aroclor is confined to Depts. 235, 24J, 245, 246, 258, 270, 273 and 275, and that there is a possibility of carry-over to 217 in the HC1 off-gas. Will you please consider your operations for other possibilities and take appropriate action to prevent any further loss to sewer" Do we ever drain Aroclor from transformers? Vie will furnish analytical results when available. kbbn-u. lLL. / Clarrle Buckley MOMS Technical Services Departmen 097265 MONS 09 7i66
