Phono: (3* t> Ef/.-1000 , ' 5 February IC, 1970 Dear Sir: ) I Recently several newspaper and mr raiino articles have hoc:: published indicating that Polych1 or i nht.ed Biph myls (PC?iS) rj?.v? beer: ii'-coveied at some pui.Ls in some marine, aqvalic and wildlife environments. The quantities detected are said to be in Use parts per million and parts per billion categories. i- . . It is claimed that the FCBs found s trongly resemble chlorinated biphenyl; containing 54f/o and 60% chlorine by v eight. Products which are sold by Monsanto under the tra.de names of Arocloi'S 125-1 and 1260 dc. contain chlorinated biphenyls. In addition to Arociory 12nd and 1260, Men can to sells certain functional fluids contain.: ::g Arcelor I 1251. These Include Pydraet3 625, Fydraul3 AC, Pydraul 1 AC - Win ;cr Ciadi, Pydraul3 510, Therminol'' FR-3 and certain diclecti ic formula '.ion s. Sc vc). al othe r companies around the world also produce products containing chlorinated. biphenyls. % . A '" ' As your supplier of Arocloi 1254 and 1260 ana formidated products containing 1254, \vc wish to alert you to the potential problem of environ- . mental contamination as re|erred to in the newspaper and magazine arti cles. Y/e would like to point out the following additional facts: 1. Products such as Pydraul^ 90,135, 230, 312, A-200, F-9, 150, f'S\ * , and 60, TurbinoP' 153 and Therr/uno, FR-1 and FR-2 are not . formulated with Arcelor^ 1254 or 1260. 2. FCBs v/ith a chlorine'content of less than 54^ have not been found in the environment and appear t.o present no potential problem to the environment. v \ . i * -r ** 'uA * DSW 338199 18 M - * - ' y STLCOPCB4082039 1 pM O' " . ) * \iC lie: C'' velop* oO, and i'!ri now tvstinrVh new Tor v^s:.ulalior. to replace the A rode y/ 5'4. and J?.60 c.ornpoiv: ;:i-; in ouv Fycv.Hvi'' prodv.c '.5.

We feel that all possible care should be iukon in the application, processing and effluent disposal or these pro-Juris to prevent them becoming environ mental contaminants. OX interest to you may be an article in Chemcal Week, October 29, 1969, regarding water pollution standards set by each state in the Union. It ic attached. This arlicle reflects that good manufacturing practice ir< the future may require that no product vised by any company should find their way into-waterways. We. realize that you have marketed or may now market transformers and other electrical equipment containing dielectric fluids which include Aioclcr*"' 1254 and 1260. Although these fluids are sealed into such equip ment it is recognized that occasionally the fluid may be lost through leaks resulting from equipment misuse or equipment repair necessitating replace ment c: the fluid. Since the dielectric fluid contained in this equipment is only an incidental part of the over-all unit manufactured by you, we are not notifying the purchasers of such equipment of the potential environmental contamination problem described in this letter. We do recommend, however, thait you notify such equipment users of this problem. Sincerely yours, lb Attachment Donald Olson Director of Sales Functional Fluids Group DSW 338200 STLCOPCB4082040
