FDA Approval By the end of tills txjnth the plant hopes to complete a uonitoring program on the biphenyl still to establish the minimal biphenyl content that can be ex pected in dnntowax. This will determine the theoretical amount of chlorloatad blphsoyl which night be expected In Aroclor 34uO. Direct aeasureetent of chlori nated biphenyl In HktiO still owaitfl the development of a suitable analytical nethod by Id Jdntry. low Color Aroclor 54uO You Indicated In your mm of 4/24/65 that the potential for low color Aroclor 3460 was really contingent on PDA approval. Short range we plan no activity on this other that laboratory preparation of a suitable quantity for samples and a re-estimation of manufacturing costs by the pleat for operation at a 1 M lbs./yr. level. Facilities for production of low color material are not Included In the scope of C1SD project and will be considered later. If and when Justified. Molten Aroclor 54oO ln_the same cierao you indicated the possibility of one or two customers at the 1 M lbs./yr. level who night be Interested In molten uaterlal. A quick look by the plant indicates a required capittil expenditure of approximately $40 N and container and distribution savings of about $US M per year at the 1 H lb. level. This appears to be an economically attractive approach If we can move suitable volumes. At present there la no activity In either Central ShglneerIng or the plant to install such facilities and none la planned until we receive further gu! iance. One obvious unanswered question at this point Involves heat stability of Aroclor 3460 kept molten over extended periods of time. If we are really serious about molten shipments, this needs to be pursued. /Is John . .-.tilth 03378*10 I TOWOLDMON0057585
