TC: K. A. Broun pROvt: H. C. Duecker CC: OATS: SUBJECT: Kay 11, 1972 Asbestos Substitute The attached article suggests to me a possible vay to turn our fibrous tresnlite to aa advantage and perhaps get the government on our tide since it is generally adaowledged that trsnolite is not as bad a pollutant as ehrysotile. Kaybe ve can naxket fibrous trenolite as a law (or nan) pollution ehrysotile substitute for applications where ehrysotile dusting occurs, e.g., floor tUe and brake linings. The acceptance of its reduced hazard nay lead to less stringent standards for us, and possibly give us sene unexpected incase. Treaollte has baen used as a substitute for Aaoslte asbestos in either alkaline or aeid environments. I an told that while there is no ccBBercial fibrous treaolite mined in the united States, a snail snoust is imported fron Africa. X heard of sn attempt by Superior Asbestos Coapsay to look for spplieatlons of Libby tremolite. Do you have siqr recollections eoneezning thist Doss it aake sense to fdlov this approach any furthert ECD:*lr Attaeteant H. C. Duecker *> * -*
