February 19, 1980 Mr. Albert Colli Environmental Protection Agency Office of Toxic Substances Waterside Mall - East Tower 401 M Street SW Washington, D.C. 20460 Dear Al: Thank you for the copies of your minutes of the meeting that we had with EPA on January 3, 1980. I do not believe that we have basic differences, but the questions drafted to correspond to your Enclosure III are as shown on the attached two pages. As I indicated, 1 don't believe there are any significant differences, but Question 2 for Enclosure III did not Include a question regarding the evaluations on health effects of non-asbestos disc brake linings or materials used therein. As Indicated at the meeting, no one has that information and the question was re-worded to determine the physical characteristics of the fibers should they be the cause of health problems. Also, where you have Questions 4 and 5, we were more specific in our Question 4. The questions had to directly address the problem and be more specific than was Indicated in your Questions 4 and 5. I believe the rest of the questions go along with the wording in your Enclosure III. After my return from Washington I went over these questions and the wording to be used with both Mr, Moalii and Mr. Armstrong. It was agreed that this wording that we show was as we understood It from the meeting. If you feel that the differences In the wording are of substance and could present a problem please let me know, as we have already sent our questionnaire to the members using the wording Indicated in our write-up. If there are problems with the foregoing please let me know. Sincerely, FRICTION MATERIALS STANDARDS INSTITUTE EWD/lmc E. W. Drislane Executive Director FMSI-0337 FMSI03644
