Monsanto MoA4Mo Company BOO N. Lindbi^h Boulevard St. Loull* Missouri 63160 Ption#: (314) 604-1000 . -April 29, 1970 Mr. W. C. McCall, President . Great Western Chemical Compare 3720 Worth West Yeon Avenue Portland, Oregon 97210 ._ Dear Mr. McCall: You are already well aware of the publicity surrounding the allegations that certain Polychlorinated Biphenyls (PCB) are environmental contaminants. It has been suggested that one possible source of contamination is the use of these materials in pesticide formulations. Even though the recommendations for the use of PCB in insecticide formulations originally came from the U.S.D.A., -Monsanto has written to Dr. Hayes, Director, Pesticide Regulations Division of U.S.D.A. recommending that his department give critical attention to the registration of PCBs as an Ingredient of pesticide formulations. We attach a copy of our letter to Dr. Hayes* ,, Furthermore, it has been decided that effective immediately, 'Monsanto will discontinue the sale 'of PCBs to any customer using or intending to use-PCB as an insecticide/pesticide carrier. By PCB we mean the members of the Aroclor 1200 ~series, namely, 1221, 1232, 1242, 1248, 1254, 126o, 1262, 1268, and toluol/xylol solutions of 1254, 1260 and 1262, plus Aroclor 4465. As our distributor for these products, we wish to ask for your co-operation in making certain that sales for these applications are discontinued . immediately. Please inform us if you intend to comply . with this request and also when the necessary action, has been taken. \ j i ; ; : r i t i j ! i j j j i ; 1 j j I I ! f I TOWOLDMONOOQ3401 -2- Thls ban does not extend to chlorinated fcerphenyls,. namely Aroclor 5060, 5442 and 5460. Nevertheless, we feel that their usage should not be recommended or encouraged further. . ' What suggestions might we suggest? We suggest formulators may wish to look at: Santolite MHP Santolite MS-30 Santicizer 261 Santicizer B-l6 Santicizer 8 We wish to point out that we do not recommend a switch, to any other product without checking by the customer- to obtain U.S.D.A. clearance. This is outside Monsanto Jurisdiction. We apologize for the trouble and inconvenience this request may cause you but, unfortunately, present circumstances dictate this course. Should any of your location managers and representatives have any questions concerning this matter, the appropriate Monsanto regional manager for the'Plasticizer Business Group will be willing to render all possible assistance Very truly yours. /dbw W.

Perhaps you am fr.-.illinr v.'ith the curt'ant widespread interest in polychlorinated biphenyls and their re ported presence in the ocoe-ynto-u. T.?ra tro -a number of publicetior.r, thee indicate cue possible serve * fa the use of tiiene materials in pesticide rer-nuletioarj. In the early 195^'o there './ore several publJ.catien.3 (see enclosed copies cf fcv.-o) which. indicated. fchifc ''Chlorinated polyphenyls': improve the residual effect cf linciano ana poeslbiy chlordano. To our knowledge there was never any raccaj'-endation by anyone for their utso on food or other crops, the principal application was to serey iv.otal or pa la tod surfaces ' to increase the effectiveness of the active pesticide against flies, ants, roechea, ellvorfish, etc. For si number of years our technical bulletins con .. - fcained references to reports by U. 3 Department of . Agriculture scientists that this type of application improvedtnc residual characteristics of insecticides. To our knowledge this usage of the chlorinated oi~ --- phenyls never devolopea to 0 cigniflcajit degree. . Ferhapg you cro aviaro that Monsanto is the sole pro ducer of polychlorinated biphenyls in the United States. Cur products are trademarked Aroclcrs. The polychlorinated biphenyls are represented by our. . Aroclor 1200 series, e.g. Aroclor 1254 is biphenyl chlorinated to the extent of 51#. ' ,' I J 1 \ ti s I I f ! TOWOLDMONOOQ3403 Dr. Harry W.
