CELANESE CHEMICAL COMPANY Chemcel Plant Bishop, Texas TO: As Listed* FROM: G. Ille GI-124 July 23, 1980 BISHOP PLANT WORK HISTORY COMMITTEE The Bishop Plant Work History Committee met on July 16, 1980 to make the final review of the Bishop Plant as it evolved since May 1945. In addition, unit numbers were reviewed and some changes made. The attached material represents the final version of the unit numbers and Plant Process diagrams. The next phase of the project includes listing the chemicals (raw materials, intermediates, products and catalysts) for each unit number as a function of time. This task has been divided primarily between Messers. Hodges, Sharp, Kerr, Beyer and Hohon. This data will be reviewed on July 25, 1980. The final task will be to form subcommittees and develop the qualitative exposure data for Operators, Operator Helpers, Shift Supervisors and some maintenance krafts. Attached is a list of Job Class ification Codes to be used by clerks in completing the Employee Work Assignment Summary. The clerks will be beginning this phase of the program this week. jk *J. M.
