Grant Medical Director Pittsburgh Plate Glass Company One Gateway Center Pittsburgh, Pa. Dear Dr. Grant: NOTE: THIS DOCUMENT D!D NOT COME FROM PPGFiuS I have reviewed with Mr. Brittingham the proposal of Public Health Service to include the Unibestos plants of Pittsburgh Corning Corporation in the study of occupational health in industry. We agree and desire the inclusion of our Unibestos plants. As outlined in the proposal, the survey would start with the Tyler, Texas plant about March 20, 1967 and would include both an environmental study and worker interview. , The study proposed by the East Texas Tuberculosis Hospital which would be similar to the Public Health Service survey should be held in abeyance until need for the more complete clinical study is apparent. Yours very truly, BMS/rh cc: Mr. R. Brittingham Mr. J. W. McMillan Mr. L. 0. Griffith, Jr. Byrl W. Stout Vice President of Manufacturing P.S. I am enclosing your file.
