Bryant - I J 60 Distributed USA reports of committee work at NEMA and ANSI to RCW delegates at IEC 10-B and CIGRE. Other nations to keep USA informed of developments. Discussion with Dr. Knust, Bayer, Germany: Recent hearing at Bonn Ministry of Health. Gerw.tmy will form committee similar to ANSI - USA. Bayer has informed all Clophen users of PCB hazard and request to return scrap fluid to Bayer for incineration or to nine other incinerators in various German cities. Discussion with P. Jay, Prodelec, France: Jay stated Sweden will ban all PCB applications by Jan. 1972, but will have Gov. license to allow use for power capacitors only. No PCB license for PCB use for ballast, motor-run or transformers. Sweden use of transformer askarel not over 10 ton! yr. Today in France - no official PCB pollution problem, as Prodelec cleaned up factory and tries to collect all scrap transformer askarel. France has large transformer askarel market. Prodelec reclaim fluid and refine to power factor of 15 %, 100C, 50 Hz and color 1,500 APHA. Sell this for reuse at lower price. Separation of mineral oil contamination is main problem. A d vise French that mineral oil content must be less than 2% W/W o r 3% volume basis to meet Underwriter's requirements. Prodelec have discontinued epoxide for transformer askarel and reverted to tin tetra phenyl, at higher cost, Reas on is epoxic deactivates earth and upsets reclaiming. Tin tot does not do this. French government has asked Prodelec to a way to dispose r - 2- fai led power capacitors Tetrachlordizenzo furane (extremely toxic) has been .found in Prodelec*s Fyralene, and Bayer*s Clophen - but not in Monsanto*s Aroclor. Prodelec believe this results from dis tillation procedure, Prodelec distill over KOH - don't know what Bayer uses. On Aug, 27* 1971 meeting will be held in Utrech, Holland by International Institute of Veterinary Pathologists whodetec ted the furane poison. Discussion with UK Delegates: UK has arrangement for incinerating scrap askarel and slurries of askarel plus earth, with Purle Co, UK has arrangements to reprocess transformer askarel and to refine capacitor askarel. No means for handling spent capacitors other than to put into land-fill. Switzerland, USSR, Holland, Italy, Yugoslavia and Czechoslovakia - all reported no activity on PC5~ pollution.
