Monsanto Monsanto Company 800 N. Lindbergh Boulevard St. Louis. Missouri 63186 Phone: (314) 694-1000 February 19, 1970 Mr. R. T. Hough, president Central Solvents & Chemicals Co. 2540 West Flournoy Street Chicago, Illinois 60612 Dear Sir: Recently several newspaper and magazine articles have been DUblished indicating that Polychlorinated Biphenyls (PCBs) have been discovered at some points in some marine, aquatic and wildlife environments. The quantities de tected are in the parts per million and parts per billion categories. It is claimed that the PCBs found strongly resemble chlorinated biphenyls containing 54# and 60# chlorine by weight. Products which are sold by Monsanto under the trade-names of Aroclor 1254 and 1260 contain chlorinated biphenyls. Monsanto has decided to notify all its customers of Aroclor products of the publicity surrounding PCBs. A copy of the letter which will be sent to our customers is attached. This letter is intended to alert our cus tomers to a potential problem of environmental contam ination through the application, processing and effluent disposal of Aroclor 1254 and 1260. We feel it is very desirable that you, as a reseller of Monsanto's Aroclor plasticizers, alert your customers to this potential problem. This should be done promptly and, ideally, all customers should be notified at the same time. A record should be kept of all customers notified, along with the dates on which the letters were transmitted. DSW 020508 STLCOPCB4008435 boot 2- - R. V. Johnson D. H. Beohtold - Chicago P. M.

Schalk You will note that attached to the notification letter ,is a copy of a reprint of an article that appeared in Chemical Week, October 29 1969, regarding water pollution standards seF by each state in the Union. This article helps to put our letter in proper context. As mentioned in the article, good manufacturing practice in the future may require that no products used by any company be lost or discharged in such a manner as to ultimately be found in waterways. For your guidance, we Intend to mail the attached letter to all our Aroclor customers around February 27. The letter will be addressed to the Office of the President at the Accounts Receivable address which we hold in our files. We will send you sufficient copies of the letter for your needs in notifying your customers. To help you further, we have drafted a cover letter which you may wish to use in notifying your customers. A copy is attached, but the decision whether to use it or draft your own cover letter is, of course, yours. We regret the work that this request may cause you. As a responsible supplier, however, we feel we have a duty to keep our customers fully informed on matters concerning the safe handling of our products. We are sure of your support in this matter and are confident of your assistance along the lines indicated. Very truly yours. / V.7 c W. E. Schalk Director of Sales Plasticizers /dbw 001 K. P.
