GENERAL ELECTRIC GENERAL ELECTRIC COMPANY. 1 RIVER ROAO. SCHENECTADY. NEW YORK 12305 Phon* (518) 374-2211 TECHNICAL RESOURCES 2 2May , 1972 A' Mr. A. L. HeLine Purchasing Department NABISCO, INC. 425 Park Avenue New York, N. Y. 10022 Dear Mr. McLane: y7 RECEIVED MAY 23 1972 ^^ BwuB L aaieiKs Replying further to your Inquiry of April 28 relative to PCB, to the best of our knowledge the General Electric equipment in your factory containing PCB'a Is limited to certain classea of transformers and capacitors. To meet the fire requirements of electrical codes and underwriters, the dielectric fluid of transformers installed in or near occupied premises contains . PCB. There is no substitute. One possible alternative would be to replace the transformer with a mineral-oil type, in which case the transformer would be required to be placed in a fire-proof vault or installed outdoors. PCB-contalning capacitors are widely used in the motor circuits of airconditloners and aa accessories to other small "split phase" motors; as powerfactor correcting* equipment in substations;, as a component of the ballast, in fluorescent lighting installations; and as filters or electrical wave-shape modifiers in electronic control panels,- rectifiers,, inverters, and the like. A n example of such an application is the vibration control unit of your weigher made by the Pneumatic Scale Company, which has been the subject of discussion between your people and our offices in New York and Hudson Falls. It has been estimated that 901 of industrial and. eleetrleal-power eapadtors contain PCB. Nhlle functional replacements theoretically could be manufactured, they would be too large to fit in existing equipment In many applications, and would somewhat increase fire hazards. Fortunately, both transformers and capacitors are sealed, so that in normal service there is no evolution of PCB. Failures severe enough to cause leakage are extremely rare and generally cannot occur without disruption of electrical function, which event would signal the need for clean-up and repair. The special status of transformers and capacitors Is recognized in a government report released just this week. Polychlorinated Biphenyls and the Environment -- Interdepartmental Task Force on PCB1. May 1972. One of the findings of this report (sponsored by the Departments of Agriculture, CoiaaeTce, rirr/'A A t k T n rr\ 774007 . QG E N E R A L ELECTRIC Mr. A. L.

The use of PCB* a ahould not be banned entirely. Their continued use for transformers and capacitors in the near future ia considered necessary because of the significantly increased risk of fire and explosion and the disruption of electrical service which would result from a ban on PCB use. Also, continued use of PCB's in transformers and capacitors presents a minimal risk of environmental contamination." Prom our reading of the proposed FDA rule making, it does not appear to be the Intent to outlaw either capacitors or transformers when applied in accordance with the manufacturer's ratings and installed separately from that equipment which ia in direct contact with the food, feed, or food-packaging material being processe Ve have written to the Hearing Clerk of the Department of Health, Education, and Welfare with the suggestion that the exemption of capacitors and transformers so applied be made explicit in the final version of the proposed rules.
