O'Hara Acting Chairman Mr. O'Hara Introduced Dr. Fred Ottobonl indicating that Dr. Ottobonl was on loan to the Board as a special consultant. Mr. O'Hara briefly explained the reasons for the Board's existence and the procedures for the development and adoption of standards. The Board's legislative mandate is to adopt occupational safety and health standards which are enforceable, reasonable, understandabT and contribute directly to California employees. Mr. O'Hara stated that the Standards Board represents specific Interests by law--two members represent management, two represent labor, one member each represents occupational safety, occupational medicine, and the public, respectively. Mr. O'Hara commented that the Board would consider testimony on the six Items outlined on the Board's Notice of Public Hearing so that they could determine if any exemptions to the July 1, 1979 .ban of spraying of asbestos-containing products specified in the Health and Safety Code Section 25910, are warranted--and If so--under what conditions. There were 19 letters of comment received prior to the November 8, 1978 Public Hearing. A. Ar^ there methods and processes for the use of Portland cement plaster which contains less than one-half of 1 percent asbestos that should be exempt from Section 25910(a)(2)? Mr. George Borg Riverside Cement Company Mr. Borg requested the Board to consider an exemption allowing the use of Riverside Portland cement plaster containing less than one-half of 1 percent asbestos. Mr. Gerald P. O'Hara Acting Chairman"' r Mr. O'Hara requested Mr. Borg to expand on his request for an exemption.

Are there methods and processes for the use of Portland cement plaster which contains less than one-half of 1 percent asbestos that should be exempt Mr, Borg stated that gun plastic* more from Section 25910(a)(2)? commonly referred to as stucco* Is sprayed (continued) on by pumping machines which move the stucco through hoses for spraying onto the exterior Mr. George Borg sides of structures to form the two coatings Riverside Cement Company of material. He stated that Riverside Cement Company has been using this material since 1958 and is used extensively In Southern California In the construction building trade. Mr. Clay Johnston California Lathing and Plastering Contractors Association o Mr. Johnston stated that the California Lathing and Plastering Contractors Association would like to see an exemption made allowing the continued use of Portland cement plaster. He commented that machine application of Portland cement plaster is the most economical and popular method of applying the stucco. Besides reducing building costs, it also provides a large number of jobs for skilled workers. He indicated that the building industry would be adversely affected if denied the use of the small amount of asbestos currently In stucco. He also stated that, to his knowledge, there is no equivalent material, or any material that comes close to the effectiveness of asbestos in the machine application of Portland cement plaster. Mr. Art DiGregorlo Mr. DiGregorlo requested the Board to Plasterers* Union Local No. 2 consider maintaining the current requirements regulating the use of asbestos. He stated he knew of no other way the Portland cement plaster could be moved in a productive way through the machines. He Indicated substantial stoppages in production would occur without the necessary amount of asbestos. He also commented that the alternate hand-applied a .... .. method would substantially increase housing costs. In his opinion, the only persons exposed to the asbestos are the hod carriers and plaster tenders, but indicated these . persons are protected by respirators.

(continued) Mr. Art DiGregorio Plasterers' Union Local No. 2 After further discussion, Mr. DiGregorio stated that, in his opinion, using a handapplied method would increase housing costs by 300 percent, Mr. Joseph P. Eagan Plasterers' Unlon-Oakland Mr. Eagan disagreed with Mr. DIGregorlo's comments stating that when the asbestos Is applied, It sets for two or three hours, then hardens. The mechanic then goes back and warps the surface of the cement and In doing so, separates the asbestos, thereby releasing the asbestos into the air. He stated that any asbestos whatsoever contained in cement is a detriment to the people using it and felt that asbestos was not needed. In response to Mrs. O'Grady's Inquiry, Mr. Eagan stated there were other materials available on the market that could be used In lieu of asbestos and were just as effective. He commented that If the operator keeps his equipment in workable order, asbestos would not be necessary. In response to Mr. O'Hara's inquiry, Mr. Eagan stated he disagreed with Mr. DIGregorlo' contention that housing costs would increase 300 percent without the use of asbestos. Mr. Jerry Martin Board Member Mr. Martin inquired If the material referred to by Mr. Eagan contained less than one-half of 1 percent of asbestos. Mr. Joseph P. Eagan Plasterers' Unlon-Oakland Mr. Eagan stated that to his knowledge, the material used had less than one-half of 1 percent of asbestos. .

(continued) Mr. John Moylan Plasterers' Local Union No. 66 In response to Mr. O'Harass Inquiry, Mr. Moylan stated that there were materials other than asbestos currently In use that are machine-applied. Mr. Gerald P. O'Hara Acting Chairman At this time, Mr. O'Hara requested Dr. Fred Ottobonl and Dr. Clint Yanneman to comment on the testimony received on Item "A'1 or provide any further Information relevant to Item A\ Dr. Fred Ottobonl Special Consultant to the Board Dr. Ottobonl commented that the studies which were submitted to the Board Indicated asbestos fiber concentrations In the air during plastering operations, were generally below the two-fiber limit prescribed by Title 8. He also stated the requirement of two-fibers per cubic centimeter is subject to change and may be reduced in future years. Dr. Patrick 0. Clancy Board Member o Dr. Clancy referenced a letter from the Vanderbilt Company indicating the difficulties they had in separating out the asbestos fibers from other fibers during sampling. Dr. Clancy requested Dr. Ottobonl to comment on the samplIn analysis methods that are currently used. Dr. Fred Ottoboni Special Consultant to the Board Dr. Ottobonl stated he had received and reviewed the report submitted by the Vanderbilt Company and agreed with their comments. He consented that the ability to analyze a bulk sample is very difficult when the asbestos level Is less than five percent; and at two percent or below, it would be almost invisible, using standard sampling methods. He stated that air sampling methods and routine monitoring are far more sensitive and would pick up the asbestos at a half percent or lower; however, a bulk sample sent to a laboratory Is likely to be Invisible.

Are there methods and processes for the use of Portland cement plaster which contains less than one-half of 1 percent asbestos that should be exempt from Sectton 25910(a)(2)? Dr. Fred Ottobonl Special Consultant to the Board . ' Dr, Ottobonl requested Ms. Virginia Loo, Department of Industrial Relations, to comment further on the sampling methods used. Ms. Virginia Loo Department of Industrial Ms. Loo stated that the practice of the Health Department's laboratory for the State Relations of California is one that identifies the presence of as6estos in the bulk sample, but does not count fibers because of the o difficulty Involved when other particles are present. Dr. Patrick J. Clancy Board Member - Dr. Clancy inquired if when using the standard OSHA, NIOSH sampling method for counting fibers. Is it possible to distinguish between asbestos fibers and other fibers or are more refined studies needed to identify the asbestos flhers. Ms. Virginia Loo Department of Industrial Relations Mr. Charles Ray Western Plastering, Inc. Ms. Loo stated that refined techniques would have to be used. She stated the sampling methods currently In use can distinguish If fibers are present, but cannot necessarily identify what the fibers are, Mr. Ray stated that methods and processes used for the spray application of Portland cement plaster Is within the minimum OSHA standards for asbestos and would like to continue using this method of application. <* Dr. Patrick J. Clancy Board Member In view of the testimony received, Dr, Clancy inquired why some companies were using asbestos as an additive and others were not. Mr. Clay Johnston . California Lathing and Plastering Contractors Association Mr, Johnston stated that it was not economically feasible to manufacture Portland cement plaster without asbestos nor 1$ there a demand for non-asbestos stucco in Southern California.

(continued) Mr. Charles Bush Riverside Cement Company Mr. Bush stated that Riverside Cement Company manufactures a special type of cement for hand plastering, as distinguished from the cement used during spray-gun operations. He coomented that the hand plastering cement does not contain any asbestos. In response to Mr. O'Hara*s inquiry, Mr, Bush stated that Riverside Cement Company was not selltng any non-asbestos cement for plastering In California. Mr. John Moylan Plasterers' Local Union No. 66 Mr. Moylan stated that Calaveras Cement Company manufactures plastic and common cement and are mixed half-and-half using no asbestos additives. B. Are there economically feasible methods and processes of spraytng Portland cement plaster whtch does not contain asbestos and is such a product, method or process commercially available? (Section 25910(b)(2)) Mr. Johnston stated that their Research and Mr. Clay Johnston California Lathing and Development Comnittee has been researching the problem of finding additives other than Plastering Contractors Association asbestos to use with Portland cement plaster for at least ten years. Mrs. Margaret R. 0*Grady Board Member Mrs. OrGrady Inquired if a substitute is necessary since testimony received indicated that a substitute Is not absolutely necessary. Mr. Clay Johnston Mr. Johnston stated that in order to pump the California Lathing and material by volume, an additive is necessary. O Plastering Contractors . He indicated that the material could be Association pumped at a slower rate without an additive, however, this method would be defeating the purpose of machine-applied operations.

(Section 25910(b)(2)] (continued) After further discussion, Mr. Martin inquired as to what type of additive could be used to Mr. Jerry Martin pump concrete which allows the material to Board Member flow more readily, but that was non-asbestiform. Mr. John Hoylan Plasterers * Local Union No. 66 Mr, Moylan stated that the material Mr, Martin referred to was porzolan. Mr. Tauno Lalne Laine Research and Development Company Mr. Laine stated he was an independent formulator and research chemist for stucco, plaster and gravel industries. He stated that he had 25 years of experience and that his formulations have been used by leading companies. He commented that In finishing his research in gravel products, he felt that there are means available to change stuccos and plasters to be asbestos-freeHe stated that another development had been tested lately by Hill Brothers Chemical Company utilizing artificial fibers in combination with non-metallie minerals. He stated that this combination was so promising that he felt that they would be able to complete their research by the July 1, 1979 ban and converge this material to the plasters' Industry. Mr. Dean Htll Hill Brothers Chemical Company Mr. Hill stated that they have a synthetic fiber which they have been supplying to the cement industry for stucco, plaster and various other uses, Ha stated that they are currently producing and selling about 4,000 tons a year. ..... In response to Mr. O'Hara's Inquiry, Mr. Hill stated that they produce this.product at about $250.00 a ton and would cost a little more than asbestos cement plaster.

He stated that with all the products they have tested, they have yet to find a substitute for asbestos that would be economically feasible for Riverside Cement Company to manufacture. Mr. Gerald P. O'Hara Acting Chairman Mr, 0*Hara Inquired if Riverside had tested sepiollte as discussed earlier by Mr. Laine. Mr. George Borg Riverside Cement Company ' . Mr. Borg stated that they had not tested sepiollte and had not been aware of the research being performed In that area. He further stated that Riverside Cement Company was endeavoring to get out of the asbestos business as soon as possible. Mr. Harrison B. Rhodes Union Carbide Corporation Mr. Rhodes stated that sepiollte is one of the groups of natural occurring minerals that NIOSH Is currently Investigating for possible hazards. Mr. Rhodes suggested that Dr. Ottobonl contact Mr. John Demint for further Information in that regard. Mr. Charles Ray Western Plastering, Inc. Mr. Ray stated that they test different products that are made available to them and most of the time Incur damage to the equipment. He stated, however, that they are still willing to try any other product that may seem reasonable. .

If exemptions for any substances containing asbestos Is granted by the Board, at what level should the time-weighted average * concentration limits or celling concentration limits be set? (Sections 25910(b)(3), (c)(3), and (d)(3)) Mr. Rhodes stated that the simplest and most direct manner of regulating time- Hr. Harrison B. Rhodes weighted average concentration or cetling Union Carbide Corporation concentration limits, would be to use the same levels that are currently used for other asbestos material. Mr. Charles Ray o Western Plastering, Inc. Mr. Ray stated that they could continue to live with and stay well within the existing OSHA minimum standards governing time-weighted average concentration and celling concentration levels of asbestos. Mr. George Borg Riverside Cement Company Mr. Borg stated that Riverside Cement Company Is willing and able to abide by the existing standards governing the concentra tion levels of asbestos. Mr. Harry Martinez Plasterers' International Association Mr. Martinez stated that time would be needed to develop an additive that could be used other than asbestos. Mr. Jerry Martin Board Member Mr. Martin inquired what the incubation period is In asbestosis afflictions. Dr. Fred Ottobonl Special Consultant to the Board a Dr. Ottobonl stated that asbestos is responsible for two types of diseases. One Is a lung disease which was caused by very high doses of asbestos during earlier years before regulations were enacted governing the use of asbestos. Life expectancy with asbestosis Is approximately 20 years from beginning of exposure. He further stated that as the work environment was cleaned up In later years, cancer was more prevetent In the workers exposed to asbestos. He commented that in the next couple of years there will be revisions made to the asbestos standard. He also stated that the problem was so complicated that he recomnended the Board not to change the existing standard regulating the use of asbestos. He suggested the Board allow Federal OSHA and NIOSH to develop a new standard on asbestos.

S. Department of Labor. Special Consultant to the Board After further discussion. Dr. Ottobonl stated that a safe level of using asbestos should be sought and did not support the contention that asbestos be banned. D. Upon what basis, If any, Mr. Rhodes provided the Board with samples should products containing and additional Information supporting his "encapsulated asbestos fibers" previous testimony. He stated that all of be exempt? (Section 25910(c)(1)) the products they are requesting exemptions for, are products which have to perform a Mr. Harrison B. Rhodes protective or structural function. Mr. Union Carbide Corporation Rhodes then proceeded to brief the Board on each exhibit submitted. Mr. Rhodes concluded his testimony by stating that the products with which they are concerned, perform a useful and valid service for industry and the general public. They contain wetted and encapsulated fibers which do not expose workers to levels In excess of those established by the current OSHA standard or by the Senate Bill 1591 requirements of one fiber per cubic centimeter. Mr. Gerald P. O'Hara Acting Chairman Mr. O'Hara Inquired what type of exposure would exist when demolition operations were being performed in contrast to spraying operations. Mr. Harrison B.

Upon what basis, if any, should "cold process asphalt roof coatings" be exempt? (Section 25910(c)(1)) Mr. Paul 8eemer N. W. Henry Company Mr. Richard Fern Chevron Research Company Mr. Beemer stated that the function of asbestos in asphalt roof coating operations is more extensive and significant than it is in other asbestos operations. He further commented that the primary function of asbestos is to regulate the flow properties enabling the material to be applied to a vertical surface without having it run off. He stated beyond that function, asbestos serves a unique purpose in reinforcing the asphalt coating to enhance Its durability. He stated that in this function, higher quantities of asbestos is used. Mr. Beemer then submitted some samples to the Board supporting his testimony. After further discussion, Mr. Beemer stated that the asbestos fiber is wetted, coated and bonded together in asphalt coatings and would not constitute a practical hazard. Responding to Mr. Martin's inquiry, Mr. Beemer stated that if the material should bum, the asbestos fibers would not become airborne. Mr. Perm stated that Chevron Research Company had spent a great deal of time, effort and money In testing additives and have been unable to find a substitute which would match asbestos In performance. He also stated that the lead time that is required to bring a product into commercialization Is quite extensive. F. Upon what basis.

(Section 25910(d)(1)) (continued) Dr. Fred Ottoboni Cl Special Consultant to the Board Mr. Harrison B. Rhodes Union Carbide Corporation Or. Ottoboni stated that fn recent years, there has been much concern over the group of high-rise buildings that were built between 1957 and 1956. During that time, very high asbestos-containing material was often used to fireproof the steel beams. , He stated that from reading the testimony received, Monokote Fireproofing is one of the substitute products which Is taking the place of material that contains between 20 to 50 percent asbestos. Dr. Ottoboni further commented that there is a problem of office workers being exposed to the asbestos-fireproofing through the air conditioning systems In these buildings; however, this problem does not exist with the new products that are now on the market. Mr. Rhodes advised the Board to act on this matter as soon as possible allowing manufacturers lead time to pull their products off production well before the July 1, 1979 ban. ADJOURN Mr. SeraId P.
