THE PROBLEM The presence of materials identified as polychlorinated biphenyl (PCB) in marine environments was first noted by Professors 0. Widmark and S. Jensen of the Institute of Analytical Chemistry, Stockholm, Sweden and reported in l^ovember, 1966. Since then and with increasing frequency, other investigators have identified PCB in marine and animal life. Increasing evidence has been noted that indicates PCB in ubiquitously present in the environment end is resulting in damage to the ecological system. Monsanto is a major producer of PCB (Aroclors) worldwide end has been mentioned in many of the reports. II. M S I C STRATEGY With the growing evidence of the presence of PCB and the apparent damage it can do to the world environment, Monsanto must respond as a responslb]e member of the business world genuinely concerned with the welfare of our environment, yet not take premature action which would compromise its responsibilities to itB customers, shareholders or employees. Finding ourselves on the NfcV Q i l i i l ? 780755 defensive, lacking considerable information to help in arriving at sound business decisions and with no real influence regarding the timing of any precipitous action by the press, competitors, public or governmental agency, we are forced to commit our limited resources in several directions. Some of our effortB are being expended seeking information to help better understand and control the problem and some effort is being expended to find alternate products which we may or may not require as indicated by new research data or other developments. Early reports had Indicated that the polychlorinated biphenyls with 5 and 6 chlorines were being Identified in environmental samples. Prom this information it was surmised that the lower chlorinated biphenyls were being degraded and probably were not a problem. Conse q u e n t l y ^ decision was made to plan to discontinue the manufacture of Aroclors 125*+ and 1260. Recent data, although still very preliminary, indicates that not enough information is available to Justify this action. It appears that in those uses where control of spillage and disposal can be rigidly exercised and the Aroclors are in sealed containers; e.g. transformers, the manufacture ol% Aroclor 125*+ and 1260 should be continued. The advantages of using these Aroclors, particularly \ where safety is a prime consideration, far outweigh NEV 031213 780756 -3- the potential threat to the environment. III. OBJECTIVES The overall objective of this plan is to manage the PCB pollution problem to prevent It from adversely affecting the established Return-on-Investment objectives of the Functional Fluids and Plasticizers Groups, while main taining the corporate image of Monsanto as a responsible and respected member of Industry worldwide. Objectives supporting the overall objective are as follows: !L. Reduce and effectively control the PCB content of all effluent from Monsanto plants. ? Inform customers of the PCB problem and the importance of preventing environmental pollution both attheir plants or by their products. 3. Develop products to replace Aroclors for those uses in which Aroclors have beer demonstrated to be harmful to the environment and cannot be prevented from escaping into the environment. 03^19 780757 1 -4- 4. Develop reliable analytical procedures for determining PCB content of liquids, gases, or solids. Develop methods for effective disposal of wastes containing PCB without contaminating the environment. 6 . Develop methodB for reclaiming and reusing off-grade fluids containing PCB. 'r. Determine effects of P C B 's on birds, aquatic life, animals and humans. 8 . Establish and maintain favorable relationships with the press, governmental agencies, the public and the universities. IV. ACTION PLAN L. Objective - Reduce and effectively control the PCB content of all effluent from Monsanto plants. Status - A tentative target of 10 ppb of PCB in plant liquid effluent has been established. Plants at Anniston, Alabama, Newport, Wales and Sauget, Illinois have monitored plant effluents and taken action to lower P C B 's in the effluent. Target of 10 ppb not yet acnieved. NEV 031220 780758 I - 5Actlon - All plants to continue emphasis on control to achieve target of 10 ppb In effluent. Responsibility - Manufacturing Manager Date - B y September 1, 1970 > Objective - Inform customers of the PCB problem and the importance of preventing environmental pollution both at their plants or by their products. t 9 t Status - All Functional Fluid and Plasticizer customers in the U.S. have been informed. Customers in Canada, C.K., South America and Continental Europe have not been informed. Action - Inform customers in Canada and U.K. Customers in Europe will not be informed until concensus is reached by all PCB producers in Europe. Notification of South American customers .to follow. Responsibility - Sales Directors - Functional Fluids and PlaBtlclzer Croups l t Date - Canada and U.K. by May 1, 1970 Europe and South America - as indicated. NEV 031221 f-------------------- \ 780759 - 6- 3* Objective - Develop products to replace AroclorB Tor those uses In which Aroclors have been demonstrated to be harmful to the environment and cannot be p r e vented from escaping to the environment. Status - Work on product substitutes has been directed primarily at Industrial Fluids applications, and NCR Paper coating. Water-glycol mixtures, brominated Aroclors, brominated biphenyl, silicates, blends using chlorinated terphenyls with lower chlorinated biphenylB, terphenyls with phosphate eBters, phenyl ether with biphenyl, chlorinated paraffins, and fractionated Aroclor 1242 are all under study for Functional Fluids application. Alkylated biphenyls and HB-40 (hydrogenated terphenyls) appear promising for NCR Paper applications. , Action - Accelerate efforts to develop acceptable substitute products. Responsibility - Managers, Research and Development, Functional Fluids and Plasticizer Groups. Date - Meijor needB b y year end. NEV 031222 780760 - 7- Obiective - Develop relaible analytical procedures for determining PCB content of liquids, gases and solids. Status - Procedures have been developed. Copies have been offered to university and governmental laboratories. Comments regarding our procedures and comparison of results with other procedures have been solicited. Arrangements have been made for exchange of samples to verify analytical resultB. Action - Continue to refine methodology until we reach a level of competence which will provide data whose accuracy will not b e challenged. Responsibility - Section Manager, Applied Sciences Date - July 1, 1970 i Objective - Develop methods for effective disposal of wastes containing PCE without contaminating the environment. Status - Studies are being conducted on biodegrad ability, incineration and removul from water solutions. NEV 031223 780761 -8 - Biodegradability studies with aclimatized micro organisms are being conducted at Ruabon. Data to date indicates that the monochlor and some of the diand trichlor biphenyls degrade; remaining PCB's are highly resistant. Studies in St. Louis in river water Indicate high resistance to degradation. Incineration tests of 1242, 1260 and Inerteen PPO indicate combustion can be sustained with minimum fuel requirements. Stack gas samples were taken for analysis to determine degree of destruction. Recovery of Aroclors from dilute water solutions is being studied at Anniston and by MRC at Dayton. At AnniBton, adsorption on carbon is being evaluated. At Dayton, the use of acid clays is being studied. At the W. 0. Krummrich plant, the removal of Aroclors from HC1 gas streams by high temperature cracking are being studied.
