Vi, .e.-A*M"* R, Richard - Research Center ci t 4 Ml fCfc September 9/ 1969 DEFENSE OF AROCLOR F "FLUIDS------------------ TO . Wheeler - EWHEE P. Hodges. PHODG tt v } General Policy Make the Govt., States and Universities prove their case, but avoid as much confrontation as possible. Comply and work with public officials to meet or*exceed requirements ahead of time. Adverse publicity and competition are the real weapons. Analytical In Air ' - Which Aroclors are present? Where? "for ArocTor In Water- Which finmnnunciao Govt. In Animals `^'interfere? Agencies Keep track of how much contamination - which sources. Prove Bloharmful - Let Govt, prove-its case, on case by case basis. Monsanto Vlslt-Govt. Blolabs - in search of toxicological . experiments and evidence vs. Aroclors to keep up with progress, Monsanto Prove Bioharmless - Limited work at Ind. Bio-test - "Safe" toxio level for man mammals fish Rats via Chickens Fish Seek evidence of Biodegra- dation Question evidence against us. Question shriuptoxicology especially other toxic chemicals. If Aroclor bad, others must be worse. Probable Outcome We can prove some things are OK at low concentration. Give Monsanto some defense. . We can't defend vs. everything. Some animals or fish or insects will be harmed. Aroclor degradation rate will be slow. Tough to defer.; jalnst. il-gher chlorination compounds will be woroc . . . _o-`.:er chlorine compounds. Therefore we will have to restrict uses and clean-up as much as._we._can,. starting immediately. /,, / ' '> j . TRAN It-.. " l~t(- ..... . 02380? WATER PCB-SD0000004066 -2- I'nerefpre we will have to work for alternate products in end use applications; for Aroclor production facilities. Clean Up Aroclors and substitute products where necessary and when required, before threats of publicity and competitive activity over whelm us. Water Pollution seems to be first issue Aroclor product is refractive, will settle out on solids sewerage sludge - river bottoms, and apparently has a long life. Florida or Gulf Coast - Aroclor 1254 - Aroclor 1260 present issue. 40-200 ppb - causing problem at Pensacola (Monsanto) in plant effluent-causing " with shrimp. - can't risk shut-down of plant. - Federal and State can extrapolate to other plants in , Qulf area. ' San Francisco - Aroclor 1254 and 1260 Reported Aroclor to be present in San Francisco Bay. Reported to be thin egg shells in birds Lot of screaming - Great Lakes Warf studies on DOT Aroclor 1254 will be found 1 Aroclor 1242 will be found? Air Pollution - Possible spread - but less of an issue right now. -' ' Vc Analytical work more difficult. , .// - /.\ _ - Direct Contact with Product * ** 1* * * Doesn't seem to be an issue - except for food heat transfer.' 4 We don't believe Aroclor is being used as carrier for insecticide - sprayed around - / ( V,/ ,.y' ' -: I We are not positive but most uses are "closed" systems'- . , -a. or products used in solid plastics, or adhesives, or ; sealants.

Probably not burned, in A1 containers. ** Need to take care of Aroclor in discarded transformers. Product' could be drained and reworked. Probable Conclusions Hydraulic Leakage Product could be caught at machines but will take a lot of clean-up work with customers. Will have to have replacement product - with less-sensitive components. Work from this base on clean-up to prevent more pollution problems. Air Compressor Fluids It . Hydraulic Fluids Must expect 11 shrimp" experiments. West Florida State, to be "aired" sometime soon; next few months. This will lead to bad publicity and competitive action vs. all Pydrauls. We will have to try to confine to Aroclor 1254 and Aroclor 1260, TRAN 023809 WATER PCB-SD0000004068 -4- We will have to take action before that time. Gulf Coast - . Action W. Richard Fallon/ Richard Be able to replace Aroclor 1254 and Aroclor 1260 in Pydraul AC and 625 in 2 month's time before Nov. 15, 1969. Have trial product in hands of Gulf Coast accounts and distributor before Dec. 15. Fallon Suggest possible buy of "all phosphate" ester from Food Machinery. . Use this as one trial fluid MCS____ for insurance. Richard/ _ Suggest possible substitution of Aroclor 5442 for Aroclor 1254 in hydraulic and compressor blends. E. Wheeler Judges lower order of toxicity and solubility for 5^2 series. Have to test product in pump test for deposits. Fallon/ Richard. Suggest field trials of our own all-phosphate ester. Fallon/ Kuhn/ Kountz Work with large customers to clean-up streams. Bring in Findett as mfg. partner in the recycle business. Get money out of recycle operations. Inland-Waterways - /heeler/ Richard Be close enough to Great Lakes Btudies to Judge situation. Are there animals which are being affected by the concentrations found? (Richard Be prepared to replace Aroclor 1254 and Aroclor 1260 in 4 months in hydraulic fluids and in air compressor fluids. Richard Be prepared to replace all Aroclor 1242 or 124T in 6 months in hydraulic fluids. This means replacement of Pydraul 512 series, and control of sale of Aroclor 1248 to other hydraulic accounts such as Cities Service and Mobil. .Heat Transfer* TRAN 023810 Fallon/ Roush/ Kountz Systems will have some leakage depending strongly on engineering and maintenance.

WATER PCB-SD0000004069 Action Kuhn Kuhn/ Fallon Try to assure adequate production of Thermlnol 66 in face of decreased Aroclor production. Kz and terphenyl supply may become short. Switch customers to Therminol 55 or Therminol 66 ahead of pollution problems in customers plant. Work with customers on plant and dumping practices. . Findett already set up to rework. Need to make them a manufacturing arm. We get sale of recycle-rework fluid.- Capacitor Capacitor plants have re- Fiultis purification and recycle systems but up to of product can be lost by poor plant producers and off-quality material.

Capacitor products Enclosed in A1 or stainless steel for 5 to 25 year period. Will ultimately have to dispose of capaci tor products. Recommend we try to save this product for a time. Action Eng.,TSDPlant Pol lution Con trol Kodges/ Kountz Monsanto must start to work with capacitor people to clean up plant practices. We have set-up to accept material for rework into hydraulic fluid but this relocation is not a satis factory solution. Material must be reworked to electri cal grade pr destroyed, whichever is more economical Must start now to get con trol of off-grade material. Recommend replacement of future Aroclor business with other products. Have 2 years. Action Monsanto must help plant clean up of cur-tourr pl.a.ts recantation, coalescing, adsorption, cispearl of adoc.-beno or recycle of . ' Konsrr.ro badly needs "know-how" for clean-up. Monsanto should seek Govt, contract money for clean-up research, (See MRG R. Binning, D. Nelson) TRAN 023811 WATER PCB-SD0000004070 Transformers Action Benignus/ Bryant Transformer Plant can operate in a clean, efficient manner with recycle of off-grade Aroclor. Should advise disposal of filter element materials so as to minimize chance of water pollution. Incinerate or dispose. Reworked transformers pose a threat if the Aroclor is dumped into a water stream. Product transformers can remain closed and no exposure for 25 yrz. Should try to retain business by clear.-uo; by education of cut'-' tomers. Action Benignus/ Bryant Should try to minimize chance of dumping "old" fluid by re working and by educating co. shops and collecting product for rework or disposal. Dalton is set up in England to rework electrical grade fluid. Kuhn/Kountz Findett? Need rework facility here + disposal scheme. Monsanto Plants The Dept, of Interior and/or State authorities could monitor plant outfall and find ppm of chlorinated biphenyls at Krummrlch or Anniston anytime they chooBe to do so, This would shut us down depending on what plants or animals they choose to find harmed. ` Action - Take steps to see that every precaution is taken to prevent Aroclor entering water streams. Try ' to reduce to ppb level. P.Hodges-Seek a Govt, contract on adsorption and incineration TSD cycles - MRC. . Engrg.- . Kountz Take samples of streams and river water and mud evidence for before and after clean-up. Samples can be stored for further analysis if we can't keep up current with analytical determinations.

Bio-Test Wheeler Keller Ind.Bio - Test Continue studies to establish FDA type limits of toxicity on Aroclor 1242, Aroclor 1254 and Aroclor 1260, Rework with R. Keller-S. Tucker the number of samples which are to be analyzed for Aroclor in tissue. Try to see if Aroclors are changed metabolically. Does concentration level off, decline if feeding is stopped? Institute studies against the most limiting biological parameters. If shrimp are the most limiting species for Aroclor levels of toxicity, then we will have to have biological studies on these species to con firm or deny adverse findings.
