Hodges,Secretary E. V. John V. R. Richard . P. Wheeler, Chairman Objectives: (Agreed to by the Connittee) Submit recommendations for action which will: 1. Permit continued sales and profits of Aroclors and Terphenyls. 2. Permit continued development of uses and sales 3. Protect Image of Organic Division and of the Cor poration. Background Discussion of Problem: 1. Agreed that we should concentrate on Arcelor 123* and 1260 Aroclor 12*2 has not yet been Incriminated for these possible reasons: a. nature of uses of 1242 minimizes environmental contamination. b. It may .degrade biologically. c. Unless analytical techniques are performed care- fully, 12*2 can be destroyed by oxidation during the analyses. 2 PCS has been f ound in: a. Pish, oysters, shrimp, birds. b. Along coastlines of Indus trlalised areas such as Great Britain, Sweden, Rhine River, low countries, Lake Michigan, PensacoDBay, In Western wild life (eagles). It may be s global contaminant. m 3 PCS has been tied to DDT la effects on disappearance of wild birds which have fish diets. Ratio of PCB to DDT has been about *0-50^1 generally. Dr. Relsboro reported almost 1:1 ratio. PCS may be contributing to or exag gerating- the effects of other chlorinated aromatics. f MOfci 162 4 0115 i r_ f- -2- 4. Sample acceptance from the numerous researchers was discussed. This has been done on a limited fa ais. Our corroboration of testing of their samples adds to our knowledge and demonstrates a willingness by Mon santo to help define the problem but It Is expensive and also tightens any possible legal cases against us-- It rules out possibilities that Aroclors are not Involved. 5 Toxicity levels: Aroclors have be e n shown to be safe for man in rea sonable exposure concentrations. *Ve are testing 100 ppm In diet of rats and dogs on a rule-of-thumb basis that 1/100 of toxicity level is safe and 1 ppm Is probably the upper limit In total diet. "Allowable levels" are probably lower than DDT. The worst example to date is the test at Pensacola where 5 ppb was found to be toxic to shrimp in 18 days exposure. One problem we are facing is to ke e p the "safe level" (?) for shrimp from being applied to e.g. lake Michigan where more tolerant fish species probably exist. Mm need to show the safe level In 'shrimp, class, oysters and several species of fish. Many toxicity studies on PCS are underway and It was agreed to be desirable to keep contact with all lab oratories which have requested Aroclar samples. Onehalf to two-thirds of the sample requests have come from state labs (who would let us know what they are doing} and about 1/3 have come from universities (who may give us the "brush-off"). Question of who should call on the laboratories was not resolved. 6. Escambia River Problem: 7or a clearer understanding of the general problem, the situation at Pensacola was reviewed. Prom a rela tively negligible discharge of 1-3 gal/day Into a large .river, 1/5 mile downstream levels of 42 ppb In water and 476 ppm In mud were found. Although use of Aroclor was halted Immediately, we can expect the water contam ination to continue for a lengthy period by leaching from the contaminated mud. M o downstream samples have yet been taken to measure the decrease in contamination (as or 9/5/69). 6 0116 * 183 - M rtki I r \( 3- 7 Problem In Producing Plants: P. Hodges reviewed what was being done to stop gross losses at Anniston and at VOX. Basically, the work to date consists of stopping or trapping any severing of free Aroclor with return to process or land fill disposal of the trapped Aroclor. This will reduce levels in plant effluents to b e l o w solubility ranges, particularly as we move to Install traps (or sumps) back Into the waste source points where flows are small and as yet undiluted by Aroclor-frte waste streams. The question of exactly how far to reduce (how ouch money to spend) Is not yet clear and expenditures to dat. have been comparatively small. It was agreed that, unti; the problems of gross environmental contamination by our customers have-been alleviated, there la little object In going to expensive extremes In limiting discharges from the plants. One problem that has been Interfering with logical development of our plant Aroclor waste reduction pro grams has been delays In obtaining analytical results from ln-plant and ex-plant sampling. It was agreed that additional help was necessary In Dr. Tucker's lab but no specific actions were proposed. In addition to ln-plant work, the plants are sampling the rceeivia^ streams. Air pollution reduction has not been considered by the plants to date except as Incidental prevention of pro duct contamination during tank car and drum loading operations. Long range (1-2 year) Improvements at Anniston are planned to reduce product contamination ,,(and air emissions) In car loading operations. It was agreed that a comprehensive air sampling and testing program would be very expensive and la probably not Justified at this stage of the problem. 8. Environmental Contamination by Customers: Our ln-plant problems are very small vs. problems of dealing with environmental contamination by customers. In one application alone (highway paints), one million lbs/year are used. Through abrasion and leaching we can assume that nearly all of this Aroclor winds up in the environment. Because the rate of natural (bio-degradation) is very low, other degradation must destroy ?G3 equal to the rate of environmental exposure In order to avoid build-up of contamination. A general discussion was held on philosophy of contrcllln sales or working with customers to prevent pollution b y P 1: j 4 OUT MON 0181 -4Action Planned: B a c h member of the group will submit to ttoo other members for consideration possible Ideas and progress to help accomplish the overall objectives set by the Committee.

Minckler and T. X. Smith, Jr., dated April 15, 1&69, recommending the expenditure of $1,100,000 for ' the expansion of the solid Aroclor^facilities at the Anniston, Alabama plant, was submitted to the members in advance of the meeting. This expansion will enable the Company to supply Into the niid-igTO's all forecasted U.S. chlorinated polyphenyl needs and also to provide a significant share of ex-USA demands. Upon motion made and seconded, the following resolution was unanimously adopted: RESOLVED, that the expenditure of $1,100,000 for the expansion of the solid Aroclor^facilities at the Anniston, Alabama plant, is hereby approved.
