Monsanto MONSANTO INDUSTRIAL CHEMICALS CO. 800 N. Lindfitrgh Boulevard St. Louis. Missouri 83188 Phone: (314) 894-1000 January 31, 1972 Dear Sir: We are writing to tell you that effective June 30, 1972, all Pydraul fluids will be a new formulation. We have decided to stop using polychlorinated terphenyls as a component in our fluids. Our new fluids will contain no chlorinated components. In order to make a smooth transition to the new Pydraul fluids, we will continue to manufacture fluids with the current formulation until early in the second quarter of 1972. At that time we will'begin phasing in the new formulations and phasing out the old. We expect to complete this transition well before June 30, 1972. In the meantime we will make every effort to contact each of you, our customers, individually. We would like to work out with you the details of this transition so that it best satisfies your needs.- Yours very truly, Howard Bergen, Director Specialty Products Group Monsanto Industrial Chemicals Company lb ECU 001649 unit of Monsanto Comoany PLAINTIFF'S EXHIBIT 000023 WATER PCB-SD0000052875
