NINUTES OF PREVIOUS MEETING
The Secretary read a summary of the Ui.nutes of the }ieeting held Februaey 16, 1973. These minutes had been released and a motion for their acceptance had been obtained.
Upon motion duly made, seconded and unanimously passed, it was
RESOLVED: To accept the minutes of the February 16, 1973 meeting as distributed.
LABELING
At the February 16, 1973 meeting, the Secretary was directed to distribute information on typical CAUTION labels now in use. The purpose of this distribution was so that the Committee 11embers could review what is available and would be in a position to propose label specifications to meet the OSHA requirements.
One member suggested that the size of the labeling used should be of sufficient size to be noticeable on a large carton and should be commensurably smaller but

still noticeable on a smaller package. One member was using an insert with a CAUTION label stuffed into the package. The use of imprinted CAUTIO!~ labels on the carton is desirable because it is essentially a one-time tooling cost. The use of separate labels is a continuing added direct expense. Host metrbers now using separate gummed labels will eventually go over to imprinting the carton when ordered.
ln what must be a response or a reaction by others, many customers are now e8king Members about bow much percentage of asbestos is in the brake linings. This could be a reaction on the customer's part as to whether they would have to put control practices in their factories because of the asbestos that is contained in brake lining. To meet the true spirit of the OSHA regulations, manufacturers doing subsequent drilling, grinding or cutting of asbestos containing brake linings should use the care that OSHA suggests.
One member felt that where be was shipping drilled ground lining sets that be would not have to imprint these small cartons with the OSHA CAUTION label. Other members are simply putting the OSHA CAUTION labeling on everything. When it was suggested that the Committee should take a position on this labeling requirement, the members of the Committee were referred back to the Resolution that vas made
on February 16, 1973. This Resolution said, in effect, that OSHA labeling
practices should be adhered to where asbestos containing materials do not have asbestos fiber completely locked in or where subsequent operations may be performed. The question concerning the drilled and ground set is: 'While it is unlikely that subsequent operations will be performed, is it possible that they may be performed?
After a lengthy discussion it was decided that no resolution concerning recommended CAUTION labels would be proposed. Rather, the Secretary is directed to
send to the Heubership copies of typical labels now in use.
It l~as called to the Secretary's attention that his yellow Bulletin of March 30,
1973 was in error. In that notice it stated, "Avoid breathing dust". The word':-
ing should have been, "Avoid creating dust". This error will be called to the attention of the l1embership.
The Chairman brought up another point as regards labels. There is a sign that can be posted in the factory where there are restrictions concerning asbestos dust in the atmosphere. This is a standard sign for placing in the factocy which says: 11CAUTION - Asbestos dust hazard; avoid breathing dust; wearassigned protective equipment; do not remain in area unless your work requires it; breathing asbestos dust may be hazardous to your health". Information on the availability of these signs will be sent to the Membership.
EPA EMISSIONS STANDARDS FOR ASBESTOS
FMSI 06359
l-lhile the new EPA ernssions standards appear to be reasonable, there is some
difficulty in interpretation. For example, the standards are not simply "No

(2) one could even have visible emissions if they were using a collector with the specifications reconnnended by the EPA. In other l~ords, if you have the
EPA's recommended collector you could possibly have visible emissions and still
be complying with the.EPA requirements. It goes without saying, that interpre-
tation of the requirements by _individuals in the different EPA regions may vary
quite a bit.

as the dry-bag callector. lf an EPA Enforcement Officer sees a vapor from the stack where a wet collector is used, the~source best.be able to prove there is no asbestos being discharged. In other words, it can be inferred that if a source
has wet collectors they may more likely be cited for visible emissions.
lofuile it is apparent that the EPA's emissions standards promote the dry collec-
tion of asbestos in bags, many problems have been indicated with these collectors. One of the problems was repeated fires in the collection system. Another member stated that he too bad this problem until cigarette smoking was banned in the factory. Since discontinuing smoking in the factory, he claims they have not had more than one or two fires in _the last 25 years. Another meuber said that may be, but they have bad a No Smoking rule for many years and they still have fires. This party blames the fires on the incentive program where the workers receive a bonus for exceeding certain work standards. This promotes the taking of heavier cuts with grinding wheels and creates sparks which apparently promote the fires in the system. The operation that has not had any fires for the past
25 years does not have an incentive system and does not permit smoking in the
work place. Where the wet collectors are now in use, apparently the EPA is permitting their use as complying with the requirements.
At this point, the disposal of the materials picked up by the collectors was brought up. One member sent the dust to a pelletizing machine. In this process
they add 5%-10% cement to the pelletizer. A volume reduction in the order of 3
to 1 l-Tas developed. The pellets are taken by truck and dumped as land fill. Uhile the pellets could be broken down into a powder, if they receive reasonable
handling they can be readily moved from the pelletizing machine to the land fill operation. It is this member's intention to install a vacuum system from the collecting areas to go to a central pelletizingmachine. One member described his handling of dust from (1) a central collector, to (2) a screw conveyor, to (3) a truck, and to (4) the land fill. The workers in this case use respirators.
The pelletizing operation not only reduces the transportation cost by three times but eliminates the need for a watering truck and an individual to wet down the land fill. However, the costs of this pelletizing equipment are substantial. A
manufacturer of pelletizine equipment is Ferro Tech Inc., 1231 Banksville Road, P~ttsburgh, Pa. 15216.
Several members mentioned that in dealing with the EPA Regional Offices they were having difficulties deciding what was a "new source" and what was an "existing source". Also, where one manufacturer adds one machine to an existing collection system he may not be in compliance without getting a Waiver of Compliance. Appar-
ently the EPA will not give a Waiver of Compliance that will take more than 12
months to complete. An applicant must give the steps to be taken and the schedule
to be met. When each date arrives, the applicant must advise EPA concerning completion of that stage of the sChedule.
One member felt that -.;.re should review the EPA source repo:ct form to get a better understanding of -.;-.hat they -.:1ere calling for. Page one of the report would be us':d for each factory. As there l.rould most likely be several points of emission, page 2 l'7ould be completed for each stack_ or collector that emits asbestos.
If a manufacturer wished to make an addition or modification in his plant with equipment that might put asbestos into the atmosphere, he must file with the EPA. On page 1 of the report he would cross off the words "Source Report" and type in either "Application to Construct a New Source", or "Application to Modify Existing Source". In reviewing page 2 of the report under "Process Description", some questions came up as to how to complete this section. One member l.rho had worked on this report with the EPA said you should enter here the type of

machinery used without quantifying. Another member indicated that the EPA insisted that he list the type of equipment and the numbers of each piece of equipment. If the EPA specifically said to list the ntJIIIbers and types of equipment in this section it was suggested that they '117ould have said so on page 2 of the report. The question of putting down the numbers and types of equipment could become very cumbersome where a manufacturer wished to move a grinding machine from a location with one collector to another ~ocation where it would be hooked into another collector. The member '4mo filed with the EPA worked on reports in 2 different jurisdictions: New York and Tennessee. Be indicated that at neither location did be enter the number of pieces of equipment on this form. (Since tbf meeting he called to advise that the application filed in Tennessee without quantities was accepted by .the EPA. His application in Uew York State bad not been either accepted or rejected as of June 4, 1973.) It would appear that Regional Offices are not in agreement as regards quantification of the equipment under the "Process Description. '1
The question came up concerning interpretation of question 3, the "Amount of
Pollutant." In many factories a set of dry mix brake blocks could emit
into a collection system at the mixer, at the briquette press, at the cut-off
1t1heels, at grinding, at drilling, and at inspection and boxing. The problem is
that this is the il&me original asbestos which entered the process and might

one in
million pounds of turn, would make it
appear thac eignt million pounds of asliestos 1s go1.ng into the operation. From
the wording of the form, it ''~ould appear that this is exactly what the EPA wants.
However, another member was told that this in not what the EPA wants. He suggests
that if a factory takes in one million pounds of asbestos into the process that it
should not report in total more than one million pounds of asbestos. If he had
10 different emission points, he would divide the one million pounds of asbestos
by 10 to give the 11amount of pollutant." Again, their apparently has been a
difference in interpretation from different Regional Offices of the EPA.
On page 3 of the report, under ''Waiver of Compliance," it was stated that Sections 2a and 2b did not have to be completed unless EPA specifically requests this information.
INSTITUTE SEMINAR ON SAFETY AND HEALTH
At the February 16, 1973 meeting, suggestions were made that the Institute
consider the sponsoring of a seminar for members associated with plant operations. The Institute indicated it would be willing to sponsor such a seminar if suffi- .
cient interest developed.
A question was raised as to whether this seminar would apply only to asbestos. The Secretary indicated that suCh a seminar would apply to any field of interest but it should be related to problems that can be tied into State and Federal regulations. Among the topics suggested for a seminar were the following:
Air sampling and asbestos concentration determination.
The pulmonary function test and X-Ray.
Possible extension to include noise and heat stress. Cooperation between management and workers in meeting the
regulations. Asbestos bag opening machinery.

The Secretary was directed to malte up a list of subjects which lpight interest the Uembership and to canvass the members as regards their interest. In addition to the agenda items to suggest to the Hembership, it was suggested that the canvassing letter ask if an individual from that ~~~ember company would attend, where the meeting should be held, and when the meeting should be held. It was indicated that a meeting in the late fall would be desirable and suCh locations as Chicago, Detroit, Pittsburgh and Paramus were suggested.
When the Secretary has prepared a questionnaire it will be submitted to Mr. Feierahend for his review prior to distribution to the liembership. The actual
agenda will be drafted after the members have indicated their preference. The question was raised as to whether outside speakers would be involved and it ~as suggested that we were not interested in a commercial pitch at the meeting. Johns-YiBnville had indicated an interest j.n approaching such a seminar with the idea of promoting their HEAP (High Energy Air Filter) pollution control equipment. It was suggested that perhaps it might be wor.thwhile to have outsiders make presentations concerning asbestos bag opening equipment, pelletizing, collection, etc. This will have to be worked out at a future Committee meeting.
Brake and Clutch Emissions Generated During Vehicle Operation
This particular study was run by Bendix Research Laboratories under sponsorship of the EPA. A paper was presented to the S.A.E. by Dr. ~t. Jacko and lfr. R. DuCharme. of Bendix, and Ur. J. Somers of the EPA. The actual report to the EPA is a massive document explaining every test procedure and every method of collection used in the study. A technical paper was presented by these 3 gen-tlemen at the SAE Meeting in Detroit in Uay, 1973. The study essentally centers on how much asbestos is being put into the atmosphere from brake linings and clutch facings. As Dr. Jacko was in charge of this investigation he discussed the paper at our meeting. He advised that a condensed version appears in the magazine AUTOMOTIVE ENGINEERING. Among the points that Dr. Jacko made was that there were problems where a brake on one side was enclosed and the other brake was open to the regular atmosphere. Hodifications had to be made involving cooling of the outside of the shroud so that there would not be too great a temperature difference from the left side to the right side. This was more of a problem with the disc brakes on the fronts. Actually with the necessary cooling, there was hardly any difference between the drum brake rears side to side.
Among the items discussed in the paper were how much asbestos is used in frict~on materials. It is indicated that there are about 103 million pounds of asbestos in the friction materials which are used in the United States each year. 111ere apparently are some differences of opinion as regards how muCh asbestos is involved but it generally falls in the 90-120 million pound range. Actually, the amount SUbject to wear is about 66-2/3% of the actual lining that gets on to the brake (after grinding). \fuen asbestos is being used in brake linings it is discarded in one of three ways: It gets deposited on the surfaces of the brake, such as on the caliper, and around the wheel cylinders. (This is surface debris). Additional materia~ is collected on the lining surfaces, in the rivet holes, and on the brake drum. (This is called sump debris) Additional material becomes airborne and is collected on membrane filters. (This is called airborne debris). It is this latter airborne debris that the researchers are seeking to quantify.
Based on the samples that Here collected, the conclusions were that more than 99.7% of the asbestos in the brake lining is converted to other products. By extrapolating the data that they were able to develop on a passenger car the researchers indicate that a total of 5060 pounds of asbestos is put into the

atmosphere. This airborne asbestos emi~sion is 3.2% of the total asbestos
emitted from all automotive brake lininp,s and clutcll facings in the U.S.
A question arose as to what happens to the asbestos debris that drops out. Does it eventually get into the atmosphere? It was indicated that based on the study of other materials that apparently there have been build-ups suCh as lead along the sides of turnpikes. This material apparently goes into the earth's surface and whether it is picked up again is dependent on other factors suCh as the proximity to streams, etc.
A gentleman. from Ford Hotor Company was also to present a paper to the SAE meeting concerning asbestos particulate emissions into the atmosphere. No paper was available at this time. There were some questions concerning procedures and a source of data on the Ford paper but in any event the paper indicated a lower total asbestos emission than the Bendix paper. These two papers should serve as source information when others are attempting to quantify the asbestos emitted into the atmosphere from brake linings and clutch facings.
OTHER !TEllS
The topic of OSHA inspections and enforcement was brought up briefly and the members indicated that no new actions bad been taken by OSUA as regards enforcement concerning the asbestos standards.
The Asbestos Information Association (AlA) is to put out a Compliance tIanual concerning control practice. This is still preliminary and there is no advance copy available at this time.
