May 3, 1974 the Federal Register published clarifying revisions to the EPA National Emissions Standards for asbestos. They exempted "fabricating" which would cover the rebuilding or the re-oanufaccuring of brake shoe assemblies. The definition of manufacturing was clarified to indicate those sources that process commercial asbestos into a produce. It does noc __ consider a manufacturer to be one who cuts, shapes, asaeables or otherwise . ' altars a manufactured produce chat contains asbestos.' . This, would leave che rebuilding operation outside of the scope of the national emissions standards for asbestos. . ' . I4 these clarifying rtvisloos they also give tbs definition of a visible emission. In essence it was seated that the "no visible emissions" require* sent does noc apply to uncombined water if that is the sole reason for failure. An additional section on these qualifying revisions wee that dealing with disposal of asbestos waste produces. The agency will determine whether It Is ' necessary to regulate these sources. No specific stacsaaat waa made concerning waste disposal practices but the agency did indicate that they v*re going to look into this problem. * Mr. Weaver advised thee the EPA is considering steps-to improve- on the emissions standards and in particular la considering a numerical standard rather than the "no visible, emissions" standard. Ihere is no specific report of progress in this area as regards the EPA Emissions Standards. STATUS OP THE OSHA REGULATIONS During the year a suit was broughe by the AFL-CIO against the Department: of Labor concerning the Occupational Safety & Health Act. Their petition waa aimed at strengthlng (not weakening) OSHA regulations. The U.S. Court of Appeals rejected their petition for review. In essanen the OSSA Regulations stand as they were originally presented. . There is consideration of changing che OSHA- Regulations to be more woric- practice oriented rather then based on numerical standards. Mr. Weaver advised that the Labor Department no longer plans to completely rewrite the standard. Apparently they will try to work in sections on work practices such as housekeeping, warehousing and ocher areas. There is very little likelihood of any easing in che two fibers/cc standard that is to go Into effect in 1976. There may be additional recommendations concerning practices to be used when introducing che asbestos fibers into che manufacturing process. In addition they are calking of monitoring techniques, medical surveillance and waste disposal. In response to e question it was stated thee a respirator may be used for interim use when one is working twards getting che work piece down to che five fibers/cc limit. However, the respirator is noc a permanent solution. MONITORING METHODS FOR SAMPLIHG ASBESTOS A question ccae up concerning the EPA's measurement of asbestos concentrations in place of the "no visible emissions" standard. Mr. Weaver indicated that che EPA would like to gee some kind of e measurement that they could rely on. ~ TI Minuets of che Asbestos Study Coiaaittee -3- June 14, 1974 v Ic vu seated char the membrane filter method with the optical microcope *cill leaves e lot to be desired. Work is being done on electron microscopy. Problems exist on hcv to satisfactorily pick up Che sample chat is to be measured. Dr. Jacko indicated thee he hid been working vich the iluclepore filter for their study for the EPA concerning asbestos emissions from motor vehicle brake and clutches. (The Millipore filter is used in the OSHA Regulations.) ' . .' A paper vee shown that had been presented by the Franklin Institute Researdi Laboratories for EPA. This report was entitled, "DcveloptMae of an Instrumental Monitoring Method for Measurement of Asbestos Concentrations in or near Sourcas". This used scanning electron microscopy with microprobe . capability. The scanning electron microscope can see che fiber bat cannot cell the structure. The microprobe can identify the chemical structure. It might be said that che electron microscope can count while the microprobe . can identify. Further work is necessary to automate this counting. . It was stated that the current meabrana filter method can be 50Z off even : with relatively skilled obeenux*. In addition die risulcs .ary dnpmtdirg upon which section of the sample' la counted. Mention vea -made of the MUllpore . ifHC system for monitoring asbestos. This Is essentially'an Image analyzing method. The same microscope Image seen by the operator Is utilized but e digital computar performs counting and maasurlag functions. / Mr. Weaver mentioned that there was instrumentation at a coat of less them $10,000 which would help in the counting. In. particular he mention** ** Coulter attachment on the binocular microscope which projects an image on a TV screen. One can measure length or diameter of the fiber digitally. It la considerably simpler than the measurement of asbestos tinder a microscope and there is less fatigue involved. . It was mentioned that in the Biospherics project for EPA which checked on pollution of water by motor vehicles optical microscopy was used. Dr. Jacko indicated that he had been in touch with those at Blospherlcs who had done this work and that he concluded thee their results were reasonable. EXPANDING OF CaZCSTTEE BEYOKD ASBESTOS ' The pros and cons of expanding this Committee's activities beyond the asbestos field were discussed. While it was stated chat cany of the asbestos programs gst Into ocher problems such as work practices and plant disposal problems, it was felt chat expanding che Committee's activities into the areas of heac stress, noise and safety related problems might be biting off too much. It was stated chat there ere sufficient problems in asbestos related fields to keep chi* Commitcae busy without adding responsibilities. It was suggested that if need were to be shown for a committee to delve into work practices it would be best if a Hork practices Comnictee were established. The Asbestos Study Comictee in the meanwhile will be involved with work practices where they affect control of asbestos in che work place or the environment. Upon motion duly made, seconded and unanimously passed, ic was 1 RESOLVED: That the Asbestos Study Committee will not expand their activities beyond the field of asbestos. Any such expansion should take che fora of a new T V-f nnfM of Che Asbestos Study Cotasictee -4- June 14, 1974 AMERICAH ISDPSTRIAL HYCISHE ttESTPC Thors war* three papers to b given at thlj meeting which should have beea of interest Co cho frletloa material* business. One concerned exposure of turnpike coll booch operacors co automotive dust by Diberardinls, Burgess and Lynch. This paper vis more concerned with the exposure co carbon monoxide and ocher gases from Che lncernal combustion engine. This paper was not concerned with asbestos emissions. " Another paper vas chae concaralng observations of two brake 3-twtwg manufacturing Industrial by Cowls, Rajhans, and Moore. This paper (for acme unknown reason) was screeched from the presencations. . The only paper of direct intereat to the friction materials industry waa *' entitled, "Asbestos Zxpoeure During Brake and Repair11 by Rohl, Anderson, Nicholson, and Laager. This paper concerned with.

It ves obvious, however, that there Is e need for better ' work practices at the re-Una and installation level. ASBESTOS ISFOraiAXIOa ASSOCIATION (AIA/NA.) In January 1974 Hr. &. N. Mereness of the Asbestos Information Association wrote concerning listing the Friction Materials Standards Institute as an "affiliated association". At that time I indicated to Mr. Mereness that the Institute would be happy to consider itself an "affiliated association". In subsequent correspondence with members of the Board of Directors it was indicated that this vas premature. One director indicated that we might b exposing ourselves in an area where we now have a low profile. That is, the friction, material manufacturers are not primary offenders like chose in the construction field and in textile operations. Affiliation, as such, might move us Into the target area. Another objection had to do with the legal status of any so-called affiliation. Mr. Stickles indicated that there might be some objection to our being considered an affiliated organization and we would need more information. There were several 3oard members who indicated chat we should do whatever we can to support tha Asbestos Information Association. In our discussion at the meeting the consensus was that ve should reciprocate and support the Asbestos Information Association. Hcarever, considering the absentees at the meeting, it was decided not to make any resolution on this subject. It was suggested that this be discussed further at the Board meeting in June. Tha Asbestos Study Committee is taking no position as regards being considered . an "affiliated association" with the Asbestos Information Association. T Asbestos Study Cca^etee -5 June I . 1974 DAP STOTT - A3BEST3S WORKERS' PENSION PLANS There was a brlaf article in the April 1974 lasue of ASBESTOS magazine concerning the UAH's intention to study the occupational hazards to which asbestos workers are exposed with a possibility towards reopening pension plans for these workers. There were no additional specifics concerning the subject in the article. In discussion it appears that the study is being made at the Chrysler Corpora tion. Asbestos workers in the UAW are primarily involved with brake lining and clutch facing manufacture. There ere some UAW plants working on the Assembly of breke linings or dutch facings which could also be Involved. TMv would be the second area where UAW members might be Involved where there ere asbeseos concentrations in the work place. This would Include such breke assemblers as the Bendlx group In South Bend, Kelsey Bayes, Chevrolet Geer end Axle, and Wagner Electric. The aoee significant asbestos use In the automotive field- Is In brake lining. Clutch facings are probably doae second. However there in asbestos used ' in iir ecniltlcnlng ducts fc? sma Ford motor company vehicles. "rh1 epperenti ls che only significant use of asbestos ocher than In friction materials. It would appear therefore that any try for a pension program of "25 years had out" will be aimed at the friction materials business. ' PELLETIZING ASBESTOS WASTE PRODUCTS Mr. Dave Scone of Bendlx showed some photographs of a sophisticated pelletizing arrangement for caking asbestos dust products from their dust collectors. The process had been described at an earlier meeting. Essentially e smell amount, of cement is added and the dust Is formed Into pellets and dropped from there Into a truck-lor disposal at a land-fill. The pelletizing removes or reduces the problems with dust when a truck Is being loaded and when the dust Is being disposed of. For Bendlx, this operation did reduce the need for a watering operation at the land-fill site. Bendlx will use this pelletizing operation at both their Troy, New York, and at their Cleveland, Tennessee plant. The pellets are essentially wet balls when they are dumped, at the land-fill. - Mr. Stone indicated Chat if other parties were interested in seeing this pelletizing operation he would make arrangement through members of the Asbestos Study Committee. It Is suggested that If individuals would like to sea che installation at Troy, New York that they contact a member of che Asbestos Study Committee. FOAM SPRAY FOR CONTROL OF DUST Mr. Scone showed an article on the use of a foam spray for controlling dust in coal mines. (ANALYSIS OF FOAMEBOL FOAM AMD ITS COMPAP.ATIVE EFFICIENCY AS A DUST COLLECTOR). It was his intention to follow this up to see If there were applications for the use of foam spray in the processing of friction materials. Suggestions were cade chat if a foam spray got Into the product - during the mixing or briquecing stages chat it could have an affect on friction material. It was suggested that perhaps che best application for a product of this type was during che drilling or the grinding operations. It.was stated that one of the problems with a spray, or with a paint for that matter, on the finished produce vas chat It did have an effect on Initial brake or clutch application. This subject vas to be investigated further by Bendlx to * " " M 1 --- --14-- <* rh.lr nrocessinx. Klnuco of ch __ Asbestos Study Committee -6- June 14;-1974 EFELUEMT CUIDELTTJgS ?JR FRICTION HATERIALS MAKPTACTPRPRS llr. Weaver showed * document prepared by Sverdrup & Parcel who are consultants for che EPA. This document was entitled, "Development Document for the Proposed Effluent Limitations Guidelines and New Source Performance Standards for the Textile, friction Materials and Selling Devices Industries". Bile had been published by Sverdrup and Parcel for the EPA. Immediately after the meeting I called Dr. Btizzall of Sverdrup and Parcel. He did not have additional copies available. He suggested that I write individuals in the EPA. He gave the addresses for eoncsecing Dr. Richard Gregg and Ur. J. Z. Riley. The Secretary was directed to get copies of this document to Mergers of the Institute. There was a concurrent study being sponsored by the EPA which wo being done by Arthur D. .Little. This concerned the economic effects of SPA Effluent Regulations. The Secretary wo directed to contact Hr. Boll Igwe to sen what the-status is on this work. . USE OP BRCSHES TO SZ1L I'ACEHIHC OPERATION Mr. Vagner of Carlisle showed a simple brush that he used in his machining operations. The brush would permit the tools (or ch part depending upon che operation) to move by into the enclosure where it wo being machined (drilled, cut, other). Chips would fall down. Dust would be collected. The brush would seal the area where the machining wo being done and. reduce the duet that ordinarily would leak pot the seal. Also it permitted the dust collector to exhaust the asbotos dust with a greater vacne. They use such a device in grinding, drilling, and chamfering operations. Ur. Wagner indicated that steps such o this have gone e long way In reducing asbestos concentrations in the work place. IHSTITUTZ SEMINAR OH SAFETY A3D HEALTH At the June 1973 meeting it wo suggoted that the Inseieute consider sponsoring a seminar on safaty and health. Most of the subjects were related to the asbestos problem. After quotlonairo were sent out and reviewed It was decided by the Chairman of the Asbotos Study Committee and the Secretary of che Institute that there wo not sufficient Interest in such a seminar for ' the Institute to sponsor it. It wo indicated that the members of che Committee, or chose suggesting such a seminar, would have to taka a very active interoc in promoting such a seminar. At this time the Asbotos Study Committee does not reconmend further action as regards a seminar. There being no further business brought to the attention of the Coamittee, upon motion duly made, seconded and unanimously passed, it wo RESOLVED: To adjourn. Adjourned: at 1:30 P.M. E. U.
