conoco . Interoffice Communication To Thomas J. Chester, M.D., Medical, Ponca City From Thomas G. Grumbles, Chemicals, Houston Da January 19, 1982 Subject CONOCO CHEMICALS' MORTALITY STUDY Thank you for reviewing the subject study. I have talked with Don Norwood as to the.possible non-epidemiological uses of the "worker registry" informa tion developed. He can foresee no such use as the Personnel Department has other such data lists they routinely use for their purposes. However, as you suggested in your letter, I think we should continue to maintain the system until HISS is operational. I would hope the current Chemicals' system would assist you in getting the Chemicals data entered into HISS. Once again, thank you for your review. Thomas G. Grumbles TGG:dem cc: Jack Drumwright, M.D, CCR 000002379
