The June 21st letter should have read as follows: Peters, J.M. - NIOSH Expert Reviewer "... Rubino's study contains little reliable environmental information to match tp with the health effects." Thiessen, J.W. - Agency Reviewer, Dept, of the A m y " Fran an epidemiological perspective ... none of the articles or studies cited established a direct causal relationship between norrasbestifonn talc containing less than 1% quartz and a disease state." " None of the evidence given demonstrates a reasonable model that shews the old standard as being too high." " More toodoological data is needed concerning the health effects of relatively pure talc and talc with its associated minerals... as well as epidemiologic studies on occupationally exposed persons. Establishment of a new standard should be contingent on such studies." We apologi2e for ary inconveniences this mistake may have caused. Sincerely, Charles R.
