Lindbergh Boulevard St. Louis, Missouri 63166 Phone: (314) 694-1000 June 1, 1970 Dear Customer: You have received our letter mailed February 27, 1970 notifying you of the allegations that certain poly chlorinated biphenyls (PCBs) had been found in the environment and were contaminants. Since that time other reports concerning PCBs have been published. An examination of the PCB matter has indicated that their use in synthetic resin compositions may be a source of the alleged environmental contamination. Monsanto has sold PCB-containing materials under the trade name of Aroclor. These Aroclors included: Aroclor 1232 ' Aroclor 1242 Aroclor 1248 Aroclor 1254 Aroclor 1260 Aroclor 1262 Aroclor 1268 Aroclor 4465 Aroclor 1100 Series Montar 1 Toluene or xylene blends of the above products also contained PCB. DSW 282394 STLCOPCB4063723 Page 2 6/1/70 In review of the allegations which have been made concerning PCBs, and being a concerned and responsible member of the world community, we have come to a decision to discontinue the sale of PCB-containing products for modifier and plasticizer applications effective August 30, 1970. Recognizing that this action will result in research effort on your part to find adequate replacements, we have prepared a series of data sheets outlining suggested alternatives for most applications. Copies of the report for your application may be obtained by calling the regional office closest to you as shown on the attached sheet. We urge that you consider initiating now any necessary work on your part to effect the change to a new material. We stand ready to assist you in any way possible. Very truly yours. ek Attachment W.
