Thurber Union Carbide Corporation Mining and Metals Division 270 Park Avenue New York, New York 10017 Dear Mr. Thurber: A This is in reference to your communication of May 5, 1975 and the various information you supplied in regards to amendments to Senator Milton Marks' legislation. I would like to make the following comments. 1. I am deeply concerned over the handling of the dry materials such as the methods of mixing and the pre cautions and safety equipment which are to be used. What safety precautions and equipment would be used in the cleanup, especially of the overspray after drying? 2 I noticed the various percentages of asbestos that are in the different mixtures and find that they run as high as approximately 20%. We have many statistics to show that our people who have been exposed to less than the two fiber amount, which will become the law under 0SHA next year, are still experiencing severe difficult ies healthwise with asbestosis and the many other dis eases associated with asbestos. This includes wives, children and other people who do not know they are being exposed to the above product. We are naturally concern ed with asbestos exposure to anyone, regardless if they are affiliated or not with any individual union. 3. What consequences are experienced from erosion, abrasion, damage to the finished products, cutting, sanding, etc.? 4. Although you mention the use of just a small percent or amount of asbestos, I again question the amount which rises to approximately 20%. This is a greater percentage than many of the products we have used in the past such as pipe covering and flat block materials containing received asbestos. MAY 1 5 J975 PLAINTIFFS EXHIBIT 43971-QQ PLAINTIFF'S EXHIBIT Mr. W.C. Thurber - page two We feel that we would have to take a very close look at the many different applications, including the overspray effect, before we could reach any conclusions regarding changes in Senator Marks' legislation. We are not overly concerned about a wet or sealed in application but the effects before and after application is our main worry with asbestos in a dry state. We sincerely hope that you can answer the above questions to our satisfaction and that a mutual understanding can be reached. With best regards, I am Very truly yours. RJ S:mgm CC: Dr. Irving J.

In the interim since our meeting, we have had the opportunity to review Dr. Selikoff's letter of March 14, 1975, to you and would like to provide some comments on the questions raised by Dr. Selikoff. Dr. Selikoff apparently did not receive the detailed dust count data which CMA submitted in support of the proposed amendments and thus is quite correct in theposition that the information available was not adequate to evaluate the proposed amendments. It seems from the nature of his other questions that he is looking at this in the same light as the now discontinued operation of spraying asbestos building insulation. In insulation spraying, bags of raw asbestos fiber are mixed in a water slurry and sprayed on to steelwork and other surfaces for fireproofing. There is little or no permanent binder so the sprayed material ends up as a mater of virtually pure asbestos held in place by its own entangled fibers. Such operations obviously represent an in appropriate use of asbestos and have been outlawed. There is a substantial difference between this spraying of asbestos for building insulation and the operations covered by our proposed amendments wherein a relatively small amount of asbestos is added to a liquid binder for control of certain physical properties of the material. The os bestos in the finished coating or item is firmly held in a permanent binder. Recognition of these distinctions is essential for an appropriate evaluation of the proposed amendments. Referring to Dr. Selikoff's five specific questions, the following comments are offered: 1. All of the systems except the interior wall and ceiling texture sprays i.e. water-based systems with water soluble binders, are factory mixed and de- livered to the spraying location with the asbestos fully wetted out. The tex ture sprays, containing 1-3% asbestos mixed into the other dry ingredients are typically added to water at the site. The act of dumping is controlled by the OSHA regulations and if it cannot be done in compliance the entire opera tion should be stopped. There are moves at some locations to compound this type of spray at factory locations and pump it directly into the sprayer's tank. 2. Extensive supporting data have been supplied on this point. (See Tables I--IV attached) The maximum level found was a ceiling concentration of 1.6 fibers/cc with values of several tenths of a cc most typical. It should also be noted that in most of these counts all particles longer than 5m wi th L/D^3 that in the judgment of an experienced operator could possibly be asbestos were counted as such. This tended to include a proportion of particles that were not really asbestos. 3. Regarding contamination of adjacent surfaces during spraying, it should be stressed that the materials sprayed are being used in the finishing or as the finish for surfaces and parts. Where overspray occurs, it is normally removed immedi ately or covered with subsequent coatings. Where it is not removed, the binder sets and holds the asbestos. There are no dry clumps of unbound asbestos as could occur with the insulation spraying and which seems to be of particular concern to Dr. Selikoff. We are prepared to provide an application by appli cation commentary for the systems tested in developing the supporting data if it wilt be useful. 4. Regarding subsequent manipulation of the coated surfaces, the texture sprays (Table I) the wall and roof sprays, (Table II) and the asphaltic roof and under coats (Table IV) are finished as applied and are not sanded or worked further to any extent. Certain of the resin applications (Table III) are cut, sanded or ground after the binder resin has hardened. A substantial amcunt of fiber (V . count data has been obtained for this type of operation and wets provided in Tables V and VI. The highest level found in a commercial situation was 0.4 fibers/cc. In a laboratory test in a small closed room the maximum was 1.2 fibers/cc. 5. Regarding contamination of the workplace by waste materials, it should be noted that these materials cure or harden when used so the asbestos is bound in. An exception to this is the "empty" bags for the interior wall and ceiling texture sprays. These do present a potential exposure but are rigidly controlled by both the Federal and California OSHA regulations. It should also be noted that the removal of overspray on the floor is required after some texturing opera tions. This is noimally done wet with a scraper and the floor is then finished. * We would like to reiterate that the proposed exemptions of certain additional ques tions from SB24I9: 1. Can be accomplished within existing OSHA and EPA regulations; 2. Will generate very low levels of airborne asbestos contamination and that these dust levels are similar to those of already exempted operations; 3. Will insure the continuing economic well-being of those companies and workers in operations proposed for exemption. Your continuing consideration of this matter is appreciated. Very truly yours.

Monagan, President California Manufacturers Association * PROPOSED MODIFICATIONS IN CALIFORNIA HEALTH & SAFETY CODE CHAPTER 10.3, 25910 (CALIFORNIA MARKS BILL, SB 2419) Exempt the following, in addition to "cold process cutback asphalt roof coating": 1. Water-based interior texture sprays containing as sprayed a maximum of 3% by weight of asbestos and a minimum of 2% by weight of water-soluble starch, soya protein, polyvinyl alcohol, or equivalent binder. 2. Latex-based interior and exterior coatings containing as sprayed a maximum of 5% by weight of asbestos and a minimum of 8% by weight of vinyl, acrylic, vinyl-acrylic, or equivalent polymer binder. 3. Resin-based laminating and/or coating materials containing as sprayed a maximum of 12% by weight of asbestos and a minimum of 6% by weight of polyester resin, alkyd resin, epoxy resin alone or in combination with coal-tar, or an equivalent resin binder. -4. Asphaltic-based coatings containing as sprayed a maximum of 15% by weight of asbestos and a minimum of 40% by weight of cutback asphalt or emulsified asphalt binder. The Honorable Milton Marks Member, California Stato Senate State Capitol, Room 2070 Sacramento, CA 95S14 Dear Senator Marks: In 1974 you carried SB 2419, which was signed into law on September 26 of 1974. This act, which added Chapter 10.3 to the Health and Safety Code, prohibited the spraying of any substance containing any amount of asbestos after July }, 1976, in or upon rtj othc* ^tructur^ cor**t^ion or Tepair, with the exception of colu process cutback asphalt root coatings. In addition to tho present statutory exemption of coal cutback asphalt roof coating, we believe that there are other applications which should also be exempted from the statute. These proposed additional execrations will in no way jeopardize the health of the citizens of California and will, at the sane time, protest the employment of workers in the California asbestos and related industries. It is our firm belief that various materials containing small quantities of asbestos can be applied safety by spraying with no significant hazard, either to the occupational worker, or the general public. And further, that such spraying can be dene in total com pliance with Section 5202 of the General Industry Safety Orders for tho State of California dealing with asbestos, and the EPA National Emission Standards for Hazardous Air Pollutants. Those applications which we propose for exemption generally involve the spraying of paints and coatings where asbestos is a miner but important constituent added to give criticaal properties to tho material. These coatings are applied-wet as a slurry or liquid, thus precluding the generation of airborne, asbestos fibers in excess of established California and Federal regulations. Specifically, I have attached a proposed draft of a bill which would provide additional exemption:* be added to tho existing statute. Supporting data from a variety of representative industrial operations in each class are provided in Tables I-IV. These data indiciitethat in r.m instance does the airborne concentration of asbestos fiber exceed eithor the tine-wei.chtcd average tor peak concentrations spasefied in Section S223 of the General Safety Orders even for the lower level standard to be invoked on July 1, 1976. Exhibit One attached provides additional information relevant to this proposal. Tnis information was excerpted frcn the federal register and is part of the EPA background information included with the promulgated National Emissions Standards for Hazardous Air Pol lutants. This material clearly indicates the undesirability of, and enforcement problems associated with, an absolute ban on asbestos spraying. Adding of these exemptions to the present statute will assure the continuing economic viaSility of those segnents of the mining. Billing, and formulating industries involved with asbestos while protecting the health of the workers and the general public. These proposed amendments are fully supported by the Asbestos Information Association of Korth .America. This organisation cons is ss of 22 Bomber companies and associations which represent three-quarters of the asbestos mining, milling, manufacturing, and importing indus tries of the United States. I would be pleased to further discuss this proposed amendBent to tho Health and Safety Coda with you at any time. Sincerely yours. RTHrrk Enclosure Robert T. Monagan President f > The proposed standard would have prohibited the spraying of any material containing asbestos on w portion of .a bulldin? or structure. prohibited the spraying of any material containing as bestos In an area directly open to tho atmosphere, ar.d limited emissions from ' ` ail other spraying ot ar.y material con- - talnlng asbestos to the amount which would be emitted if specified air-cleaning equipment were used. Comments re ceived pointed out that this standard would: (1) Prohibit the use of materials containing only the trace amounts of . asbestos which occur in numerous nat- / .-oral substances. (2) prohibit the use of : materials to which very small quantities of asbestos are added in order to enhance their effectiveness, and (3) prohibit the : ase of materials m which the asbestos is strongly bound and which would not gen erate particulate asbestos emissions. The `promulgated standard aopiies to those uses of spray-on asbestos materials which could generate major emissions of . - particulate asbestos material. Tor those : spray-on materials used to Insulate or fireproof buildings, structures, pipes, and conduits, the standard limits the asbestos content to no more than 1 percent. Jfa- terials currently used contain :rom 10- r. to 80-percent asbestos. The intent o: the . 1-percent limit is to ban the use of na- - terials which contain significant quanti- ... ties of asbestos, but to allow the use of .. materials which would: (1) Contain trace 'amounts of asbestos which occur in numerous natural substances, ana (2) include very small quantities of asbestos flesa than 1 percent) added to enhance the material's eTectiveness. Although a standardized reference method has not been developed to quantitatively deter- . mine the content of asbestos in a ma- teriat. there are acceptable methods available, based on electron microscopy, which Independent laboratories have de veloped Determining the asbestos con- ' tent of a material with these methods ; costs approximately $300, ar.d the resuits i are accurate within plus or .minus 50 i percent; these limits on accuracy were _ taken into account in establishing the . I-percent limitation. .. l V ri..*,:*v V VATtR-gASCO STSTTMS WITH UATCP-SOlUGlt 81f.:cgs jingle Comerclal Sisiicstlon 1 . lKTtRtOR TWTVe.E S"A*S 12 Celling spray. >2 3 Vail spray. 3S 38 28 36 131 102 Calling spray Vail spray.
