Subject
Natural Resources Defense Council Petition to Prohibit
The Use of Asbestos in Highway Brakes
Gentlemen
The Friction Materials Standards Institute Inc. FMSI is a trade
association of twenty friction materials manufacturers in the United
States with associate Members worldwide The FMSI has read the petition submitted by the Natural Resources Defense Council NRDC to the Environmental Protection Agency EPA for the purpose of prohibiting the use of asbestos in brakes for new cars and trucks and in replacement brakes in
existing vehicles
We wish to comment at this time on certain sections of the petition While we are not now taking a position for or against said petition we believe it is important to submit the following comments Should it be deemed appropriate these comments may be supplemented at a later date by a more depth critique We will refer to the sections as headed in the NRDC petition
I - INTRODUCTION
The stated reasons for the submission of the petition do not appear to be based upon irrefutable evidence Whether or not the occupational asbestos

standards and the national emissions standards are insufficient to
protect against unreasonable risk posed by asbestos in brakes is highly debatable Further the availability of economically and technologically
feasible substitutes for asbestos is an issue in which the friction
materials manufacturers are deeply involved The identification of such substitutes is a major ongoing program with the manufacturers and is not a completed program at this point in time
II - JURISDICTION
The FMSI concerns relate to plant regulations versus control of general
public exposure to asbestos dust While one agency has proposed to tighten worker exposure to asbestos another is being petitioned to eliminate asbestos in friction materials The disparity between these two situations
could well create implementation and economic problems for friction
materials manufacturers If asbestos is to be regulated out of friction
materials the manufacturers should not be saddled in the meantime with
compliance to new tighter regulations of asbestos in the workplace industry must know which direction regulatory activity will take

IV - CONTINUED USE OF ASBESTOS AN UNREASONABLE RISK TO HEALTH
The FMSI does not necessarily agree with the credibility of the conclusions drawn from the evidence presented on friction materials in this section Therefore the FMSI reserves the right to comment in detail on

this section at some future date
V - SUBSTITUTES
Sufficient data is not available at this time on the substitute materials to state that they do not pose a hazard in the workplace environment or
to the general public We wish to cite a recent study by the Canadian Royal Commission on Matters of Health and Safety Arising from Use of Asbestos in Ontario and an earlier paper on asbestos Related Malig-
nant Mesothelioma
These comments follow
... the production of substitute fibres in the future should
increase the exposure of workers to long thin durable fibres of dimensions similar to those we have found hazardous for asbestos we cannot be sure that serious health consequences would not result In the face of the existing evidence we believe it would be risky to allow the exposure of workers to respirable fibres longer than 5 microns with small diameters of any material if those fibres are likely to be very durable
in the lungs
It has been generally accepted now carcinogenic is a durable long and of less than 1.5 micron and length
that the fibre which is
thin fibre the diameter
of more than 8 micron
appearing critical
asbestos can appear been established as
A number of fibrous materials other than
in this size and shape and indeed have thus cause of mesothelioma in animals such as
tremolite glass fibres aluminum oxide tremolite
silicon carbide and potassium

The advantages of metallic brake linings cited in Section A are not necessarily supported by test results generated by friction materials manufacturers While certain of these claimed advantages may be true where the application generates high braking temperatures they are not necessarily true for the average consumer
Total endorsement of Section V of the petition is not appropriate
since friction materials manufacturers produce disc pads and drum segments for passenger cars and light to medium trucks as well as brake blocks for heavy trucks The claims made in Section V relate to brake blocks and cannot be endorsed for all product lines Further actual experience to date has proven that substantial processing modifications and new equipment are required for the asbestos substitute materials

An immediate ban on the use of asbestos in passenger car and truck brakes
cannot be supported because of the importance of safe brake systems on the nation's highways Brake linings are a safety related product We
stress consideration of these facts
1. There are legitimate questions on the health hazards of the fibrous substitutes suggested for asbestos replacement
in friction materials

2. There are programs in place by industry to eliminate the use of asbestos in friction materials and these programs realistically address health safety economic performance timing and materials availability issues
3 The industry must be given time to develop a total line of products which will meet all highway safety requirements
We believe the industry will accept a properly planned program pointed towards the eventual elimination of asbestos in its products We urge that
EPA study the suggested substitute materials as well as the feasibility
economic impact realistic necessity - if it exists and timing requirements appropriate to the elimination of asbestos in friction materials before responding to the petition or proposing a ban on the use of asbestos in
friction materials
