September 18, 1981 Mr. Richard J. Gulmond Special Regulations Branch Office of Pesticides and Toxic Subseances Environmental Protection Agency Washington, DC 20460 Subject: Questionnaire on non-asbaatos drum brake linings (Informational needs for friction products con taining asbestos) Dear Mr. Cuimond: On July 22, 1981 Mr. Bob Plgg of the Asbestos Information Association forwarded to our attention a series of eleven questions prepared by your office concerning non-asbestos drum brake linings. This was done as tha Friction Materials Standards Institute is In a better position to respond to your request for Information. You may recall that the Friction Materials Standards Institute participated In an earlier request from your office In regards to disc brake linings. That request was sent to our full membership of 21 companies. Our response to your office was based upon replies from only three companies as several of the others felt you were requesting sensitive information. The questions now being prepared on pon-asbeetos drum brake linings are even more sensitive to our Membership. Development work on asbestos-free drum brakes Is several years behind the work on disc brake linings. As a result, much of the currently available information Is proprietary. Be cause of the confidentiality of the information your office is seeking, the' Institute must respectfully decline the offer to participate. We would suggest that you solicit replies from the friction materials manufacturers directly. Attached is a list of what we believe to be all the friction materials manufacturers in the United States. Sincerely, FRICTION MATERIALS STANDARDS INSTITUTE EWD/erc E. W.
