Bob Tuegel of Uagner Electric Corporation has sent me a copy of Wagner's submission to the Docket for EPA's Office of Toxic Substances Control Advance Notice of Proposed Rulemaking (ANPRH) There were various eXhibits with the Wagner submission to the Docket which have been a natter of record in the.past. I did not feel it necessary to enclose copies of those eXhibits. The Hagner submission covers several points l7hich we have made in the past. It is interesting, of course, that the Hagner submission is from a manufacturer who is not a friction materials manufacturer. Host of the arguments used in the 'Wagner submission are applicable, of course, to individual friction material manufactuers. ASBESTOS HEALTH HAZARDS COUPENSATIOU ACf Prior to the Committee meeting on October 23, 1979 and the Board of Directors meeting on December 4, 1979 I had written to Senator Hart in an attempt to get a copy of the draft act for Federal Asbestos Health Hazards Compensation Awards. Senator Hart, in his letter of i:~ovember 14, 1975, indicated that he had been working on legislation and that it was still in the drafting stage and not yet ready for production or circulation. Subsequent to that I received a copy of the draft as it stood as of November 28, 1979. For all intents and purposes the Fenwick Bill '~hich had been discussed earlier in 1979 is dead. This was the Bill creating a fund by assessment on certain classes of asbestos products manufacturers. There was serious objection to the Fenwick Bill content from most of the I!embership. The Hart Bill, hcn1ever, operates within the State \-lorkmen' s Compensa- tion frameYork. Its assessment on "responsible parties" would be based on determination by hearing officers. As this is strictly draft legislation and has not been formally proposed or submitted, comments would be inappropriate at this time. It is suggested that this draft be routed to someone ~dthin your company who to7ould be in a position to review and comment on such legislation if it is reported out by the Senate Committee in the future. The foregoing is sent along as a matter of information. EWD/lmc Encs. E. W. Drislane Executive Director FMSI 06978 ., ::~ OccuPATIONAL HEALTH & SAFETY LETTER Volume 9, No. 15 GERSHON W.

The study was reported in the current issue of the British Journal of Industrial Medicine (36, 98-112). Authors were C. Berry and J.C. Gilson of the MRC Pneumoconiosis Unit, Llandough Hospital, Penarth, Wales; S. Holes and H.C. Lewinsohn of TBA Industrial Products, Ltd., Rochdale, Lancashire, England; S.A. Roach, Imperial Chemical Industries Ltd., Wihnslow, Cheshire. Dr. Berry. the principal author, currently works for Raybestos Manhattan Corp., Trumbull, Conn. What is interesting about the report is that the follow-up study was conducted at Turner Co., the same asbestos textile factory in England where the data which formed the basis of the OSHA standard was generated._ So now the follow-up data indicates that asbestosis-not mesothelioma or lung cancer-can occur at even lower. levels of exposure. The new study was called to OSHA's attention by Dr. Irving J. Selikoff of Mt. Sinai Medical Center. The same factory was examined by the investigators and reported to the British Occupational Hygiene Society in 1968. The follow-up study extended the years of observation and lung function tests were introduced, and multiple readings of x-rays were completed. In addition, former workers cooperated by returning to the factory for a medical examination and chest radiographic. FinaUy, personneland_depart- mental records provided details of aU the jobs done by all the men. This is the abstract of the new report: ..A group of 379 men who had worked at an asbestos textile factory for at least 10 years has been followed up. The prevalence of crepitations, 'possible asbestos', certified asbestosis, small opacities in the chest radiographic and values of lung function have been related to dust levels. The type of asbestos processed was predominantly chrysotile although a substantial amount of crocidolite had also been used in the past. "There was a higher prevalence of crepitations than had been observed previously at the same fac- tory. The presence of crepitations is not a specific effect of asbestos exposure and 'possible asbestosis', a combined judgment of two physicians on whether a man had developed signs which might be attribut- ( able to early asbestosis, was preferred. ..Fifty percent of men with 1 diagnosis of possible asbestosis w~re c:ertifred as suffering from asbes- -------.tosis by the PneumoconiosiJ Medical Panel within 35 yean. The most reliable data relate to men first FMS\ 06979 ... 2 Occupational Health & Safety Letter, August 8, 1979 employed after 1950; 6.6 percent of men in this group had possible asbestosis after an average length of follow-up of 16 years and an average exposure to 5 fibre/cm3 where the dust levels were determined by __ static area samplers. "The forced expiratory volume and forced vital capacity declined significantly with exposure, after allowing for age and height, but there was no decline in the total lung capacity. The transfer factor also declined with exposure, but not to a statistically significant extent. The. non-smokers and light smokers as a group had less crepitations, asbestosis and small opacities on the chest radiograph than heavier smokers with similar exposure. "Combining dust concentrations to form the cumulative dose may not be completely satisfactory, and a family of measures was investigated which allows for elimination of dust from the lungs and includes the cumulative dose as a special case. Because the rate of elimination of dust from the lungs is unknown and cannot be estimated from the data, this approach leads to a wide range of possible interpretations of the data; for example, the concentration such that possible asbestosis occurs in no more than 1 percent of men after 40 years of exposure could be as high as 1-1 fibres/cm3 or may have to be as low as 0.3 fibresfcm3. "This range is wide because the data relate to higher dust levels, and a shorter period of follow-up. Until data are available on groups exposed to lower levels, it will not be possible to assess the effects of the current standard with any certainty. However; the results of this study show that it is important to con- tinue ~o reduce tlust levels to values as low as possible~ -----~ r~ - .1 ,-,; FMSI 06980
