Coleman - Ruabon P.J.A, Marsh - Brussels R. Kountz - St. Louis A. Koenig - St. Louis W. Gordon - St. Louis To improve biodegradability eome experimental Aroclor 1242 with some of the higher chlorinated biphenyls removed is being prepared. This material has already been called Aroclor 1242B. Obviouslythe "B" implies biodegradability. We now feel that this nomenclature is not desirable at this stage of this new and not fully explored material. Therefore, we now elect to call this material MCS 1016. Please now use this designation. Instead of Aroclor 1242B. Thank you. Paul 0. Benlgnus /dn Afcr r\ TRAN 008623 3 ,-- PLAINTIFF'S EXHIBIT WATER PCB-SD0000042133
