Monsc'nio Ob N. Uhdifjh Sauttvtrtf St, loui. Miitewn 03160 n%n*. 014) 094*1000 r. . August 14, 1970 Dear Sir: ' . ' . Vou'have received our letters of February 27, 1970 and June 1, 1970 covering Monsanto's withdrawal of poly chlorinated biphenyls (PCBs) from the market. The February 27 letter reviewed some ox' the potential hazards of PC3.S and of environmental polution in general. The June 1 letter announced that we were withdrawing all poly chlorinated biphenyls-us.ed as plasticizers or modifiers from the market, and that the last shipment of these . materials would be made August 30, 1970. ' . ' In as much as you nay have some inventory of those materials which you might be planning to use during the period in which you change over to other products, we felt it impera tive to Inform you of the .latest information concerning PCEs It was recently brought to our attention that the Food and Drug Administration h3S apparently established guidelines setting forth suggested maximum levels of PCEs allowable in certain foods. These levels, as we understand them, are 5 parts per million in fish and 0,2 parts per million in milk. Monsanto, therefore, strongly recommends that PCBs not be used in applications which could lead, either directly, or indirectly', to the contamination cf food and water supplies for humans or animals. Examples of appli cations which would seem particularly hazardous would be coatings for water treatment facilities, coatings for food handling er.uiprr.ent, or coatings for such farm items aa silos and feed hoppers. Qaa46Q 31 1. 9 6; ... 'i 2- It has recently come to our attention that PCBs have been found in cows milk. This adds emphasis to Monsanto's recommendation that PC2s not be used In any application-where they might come in contact with or otherwise contaminate food, silage, water supplies, eto". The latest available bulletin on our line of Aroclors Is enclosed for your use. This publication replaces and supercedes bulletin 0/PL-30o - Arcelor Plasticizers. The only products listed which will be sold after August 31, 1970 are 1) Aroclor 1221, a mor.ochlorlnated biphenyl --htch is readily biodegradable, and 2) . Aroclors p4d2 and p`t60, both-chlorinated terphenyls which have not shown thenselves to be environmental contaminants. Please pay special atten tion to the section of'this bulletin which relates to environmental hazards;3 In addition to the products listed above which will remain on the-market, Monsanto will sell a scries of blends of Aroclor 1221 and Arocl-oc. 5*160 which will replace the poly chlorinated biphenyls for many applications." . During this withdrawal of PCSs from the market, Monsanto has had In effect a modified returned goods policy stating that unopened containers less than one year old could be returned for full credit through July 31, 1970. Prom August 1 through August 31 1970, 90 percent credit would be allowed. From September 1 through December 31, 1970, 50 percent credit would be allowed. The customer will pay all return freight. All of the dates In the time schedule for this returned goods policy are hereby extended an additional two months. . Monsanto realizes that the removal of these products from the market has caused a great deal of concern ar.d expense for our customers. This Is certainly regrettable. However, it appears' to us that as a responsible supplier, this Is the only reasonable course of action. We stand ready to assist you as we can with your reformulation work. /dbw MOWS 088461 Walter E, Schalk Director of Sales Plasticizers
