Monsanto Monsanto Company 800 N- Lindbergh Boutavard St. Louis. Missouri 63188 Phone: (314) 884-1000 August l4, 1970 .(MOANIC CHEMICALS DM8QH Pear Sir: During the week of August 10, 1970, Monsanto is sending to all its direct customers for Aroclors in plasticizer/ modifier application l) a letter summarizing the latest information on PCBs, and 2) the most recent Aroclor technical bulletin. This bulletin replaces and supercedes O/PL-306 - Aroclor Plasticizers* In as much as some important information concerning recent PDA actions and changes to Monsanto's returned goodB policy are discussed, we strongly urge you to forward copies of this bulletin and a letter to your Aroclor customers. Copies of both have been enclosed for your use. . The change in returned goods policy for our direct customers involves a two month extension of the deadlines for returning material to Monsanto. The same two month extension will apply to our distributors. A copy of our revised returned goods policy Is attached. : We realise that this additional communication provides an added workload for your people. However, in view of the importance of this matter, we feel it is necessary for you as our distributor to assist in this matter. Very respectfully. Walter E. Schalk Director of Sales Plasticisers GENERAL POLICY CONCERNING DISTRIBUTORS' RETURN OP AROCLORS* 1. The following policy will be In effect covering returned goods: a. If unopened containers purchased after September, 1969 are returned to the Sauget, Illinois plant or the Anniston, Alabama plant prior to 1O/S1/J0, 100$ of the net purchase price will be allowed for the returned goods. No additional handling charges will be assessed. Freight from distributor's warehouse will be paid by Monsanto at truckload rates. b. If unopened containers purchased after September, 1969 are returned to the Sauget, Illinois plant or the Anniston, Alabama plant prior to 12/31/70, 90$ credit will, be allowed for the returned goods. No additional handling charges will be assessed. Freight will be paid by the distributor. c. If unopened containers purchased after September, 1969 are returned.to the Sauget, Illinois plant or the Anniston, Alabama plant prior to 2/28/71, 50$ credit will be allowed for the returned goods. No additional handling charges will be assessed* Freight will be paid by the distributor. 2. Monsanto will accept orders through July 31, 1970 and will make every effort to meet these commit ments and to complete shipment as of August 31, 1970. Monsanto reserves the right to limit shipments based on its production capabilities. *Aroclors 1232, 1242, 1248, 1254, 1260, 1262, 1268, 4465, Montar 1, Toluene/Xylene blends.

Missouri B3168 Phona: <314) B94-1D00 August 14, 1970 .OfKMMC CHEMICALS OMSION Dear Sir: You have received our letters of February 27, 1970 and June 1, 1970 covering Monsanto's withdrawal of poly chlorinated biphenyls (FCBs) from the market. The February 27 letter reviewed some of the potential hazards of FCBs and of environmental polution in general. The June 1 letter announced that we were withdrawing all poly chlorinated biphenyls used 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 may have some Inventory of these 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 PCBs. It was recently brought to our attention that the Food and Drug Administration has apparently established guidelines setting forth suggested maximum levels of FCBs 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 FCBs not be used in applications which could lead, either directly or indirectly, to the contamination of 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 equipment, or coatings for such farm items as silos and feed hoppers. MCL000442 -2- It has recently come to our attention that FCBs have been found In cows milk. This adds emphasis to Monsanto's re commendation that FCBs not be used In any application where they might come in contact with or otherwise contaminate food, silage, water supplies, etc. The latest available bulletin on our line of Aroclors is enclosed for your use. This publication replaces and supercedes bulletin O/PL-306 - Aroelor Plasticizers. The only products listed which will be sold after August 31, 1970 are l) Aroelor 1221, a monochlorinated biphenyl which is readily biodegradable, and 2) Aroclors 5442 and 5460, both chlorinated terphenyls which have not shown themselves to be environmental contaminants. Please pay special atten tion to the section of this bulletin which relates to environmental hazards. In addition to the products listed above which will remain on the market, Monsanto will sell a series of blends of Aroelor 1221 and Aroelor 5460 which will replace the poly chlorinated biphenyls for many applications. During this withdrawal of FCBs from the market, Monsanto has had in effect a modified returned goodB 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. Prom 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 and 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.

One outstanding characteristic -- inertness -- makes Aroclor useful in many ways for many different applications. The major benefits offered by Aroclor include: Chemical Resistance Fire Retardance Compatibility with most resins Nonoxidation Adhesivity Low Cost Monsanto's Aroclor plasticizers comprise a series of chlorinated bi phenyls and chlorinated pdyphenyls. They vary from mobile, oily liquids to white crystals and hard, transparent resins. Twelve of the Aroclor plasticizers, each of which represents a series, are discussed in this bulletin. An understanding of the system for designation of each Aroclor should prove useful in the evaluation of the property gradations among them. The last two digits indicate the approximate weight percentage of chlorine in the product, and the first two digits indicate the type of material, as follows: 12 -- chlorinated biphenyls 25 -- blend of chlorinated biphenyls and chlorinated triphenyls (75:25) 44 -- blend of chlorinated biphenyls and chlorinated triphenyls (60:40) 54 -- chlorinated triphenyls For nearly every Aroclor mentioned, a darker, less-pure grade exists, with about the same physical and chemical characteristics, but lower in price. ___________________________ ______________ _ The Aroclor liquids and resins are readily soluble in most common organic solvents and drying oils. Although all Aroclor plasticizers are insoluble in water, the hard, crystalline materials are generally less soluble than the liquids and softer resins. Solubilities of some Aroclor plasticizers are shown in Table 1. TABLE 1 SOLUBILITIES OF AROCLOR PLASTICIZERS IN VARIOUS SOLVENTS School And* t142 ire Hat Amchr lift 2TC Hot Amchr 1254 ire Hot Amchr W!

Figure 2 over the temperature range 160 to 800"C. 10*T,*K f Temperature, C Fig. 2 -- Vapor Pressures of Arodor Plasticizers . The estimated vapor pressures of several Aroclor plasticizers at 100F shown in the following table were determined by extrapolation from the values shown in Figure 2. Approximate Vapor Pressure ofAroclor Plasticizers Estimatedat W F (37JT CJ Aroclor 1232 0.005 mm. Hg Aroclor 1242 0.001 mm. Hg Aroclor 1248 0.00037 mm. Hg Aroclor 12S4 0.0000!5 mm. Hg MCL000453 Viscosity The viscosities of the Aroclor plasticizers vary according to whether the base material is a biphenyl or a polyphenyl and on the degree of chlorination. In general the low-chlorinated biphenyls have the lowest viscosities (Figure 3). Toxicity And Safi Handliai InhtMhm At ordinary temperatures the Aroclor chlorinated polyphenyls have not presented industrial toxicological problems. The hazard of potential toxic exposure varies with their volatility: the lower-chlorinated, morevolatile ones present more of a potential problem from the standpoint of both inhalation and skin contact. When Aroclor plasticizers are used at elevated temperatures, engineering controls must be applied, either by the use of closed systems or by effective local-exhaust ventilation together with general workroom exhaust. Vapor of the liquid Aroclor plasticizers at room temperature should not be breathed in a confined space, and no vapor of any Aroclor evolved at elevated temperatures should be allowed to be dispersed into the general workroom. Inhalation tests on animals indicate that the maximum safe concen tration of vapor is in the range of from 0.5 to 1.0 milligram of the tower-chlorinated Aroclor plasticizers per cubic meter of air. The threshold limit values (maximum allowable concentration for an 8hour working day) set by the American Conference of Government Hygienists are 1.0 milligram of the lower-chlorinated Aroclor com pounds per cubic meter of air and 0.5 milligram of the more-highlychlorinated compounds, such as Aroclor 1254, per cubic meter of air. Skin Contact Schwartz patch tests on 200 volunteers showed that Aroclor 1254 was neither a primary skin irritant or a sensitizer. Prolonged or repeated skin contact with the Aroclor plasticizers must be avoided by the use of {doves and protective garments, because of the possible occurrence of a condition called chloracne. Although re ports of this condition caused by Aroclor are rare, it can be produced by excessive skin contact. If any Aroclor is spilled on the skin the skin should be washed in the usual manner with a soap solution. A burn caused by contact with a hot Aroclor should be treated like any ordinary burn. Aroclor plasticizer adhering to the burned area need not be removed immediately, unless treatment of the burn demands it, in which case either soap and water or repeated washings with a vegetable oil are recommended. 12 Environmental Hazards Aroclor 1232, Aroclor 1242, Aroclor 1248, Aroclor 1254, Aroclor 1260, Aroclor 1262, Aroclor 1268, Aroclor 4465, and Montar 1 all contain polychlorinated biphenyls (PCB) of various types and in varying amounts. PCB residues in small amounts have been found in the environment and some studies have indicated that they may be harmful to certain forms of animal life. Extreme care should therefore be taken by all users of PCB-containing products to prevent any entry into the environment through spills, leakage, use, disposal, vaporization or otherwise. Further, the products in which PCB materials are used, or which are formulated using PCB materials as a component, should be given careful study to eliminate the possibility that PCB might reach the environment as a result of use in a given application. Some specific applications where the use of PCB should definitely be avoided are in paints and sealants for swimming pools, paints and waterproofing agents in silos and other buildings where food products for humans or animals are stored, and as a component of any container or wrapping used in the packaging of food products. Shipping Freight Classification Aroclor 1221,1282,1242, Synthetic Resin, Liquid, NOIBN 1248,1254,1260,1262 Rail Classification Aroclor 1268, 4465, 5442, 5460 Synthetic Resin, Other Than liquid, NOIBN Truck Classification Aroclor 1268 Aroclor 4465, 5442, 6460 Synthetic Resin, Powder, NOI Synthetic Resin, Lumps or Solid Mass, NOI Skipping Regulations None Standard Containers Aroclor 1221 Aroclor 1232 Aroclor 1242,1248,1254, 1260,1262 Aroclor 1268 Aroclor 4465 Aroclor 5442 Aroclor 5460 (flaked) Tank car, 520-lb, steel drum, 50-lb. can Tank car, 550-lb. steel drum, 50-lb. can Tank car, 600-lb. steel drum, 50-lb. can 200-lb. fiber drum, 25-lb. fiber drum 500-lb. steel drum, 60-lb. can 450-lb. steel drum, 50-Ib. can 50-lb. bag 14 MCL000457 f 5 # | % ?it [ 15 MCL000458 DISTRICT SALES OFFICES ALL DIVISIONS AKRON.
