Corporate Director of Epidemiology Union Carbide Corporation Old Ridgebury Road Danbury, CT 06817 Dear Dr. Austin: S. G. AUSTIN, SC.D. Enclosed is a copy of the final report of the NI0SH/0SHA case-control study of brain tumors among workers at the Union Carbide Texas City, Texas plant. Please review the paper and advise us if any trade secrets are revealed in the report. We would also welcome other comments which you might wish to make* After receiving trade secret clearance, we will transmit a copy to the union (present funding shortages make it unlikely we will be able to travel to Texas City, as we had hoped). Submission for publication or other public announcement will not occur before the union has been notified. Copies of the report are being sent to: Mr. Foley Provenzano, Texas City Plant Manager Dr. David Glenn, Gulf Coast Medical Director Dr. Susan Austin, Corporate Epidemiologist Dr. William Kemmerer, Director, Galveston County Health Department enclosure Sanford S.
