/o?2-3 ,--* HON, MINISTER: In response to the letters from the Asbestos Diseases Society and lawyers*Lavan Solomon (reference my minute of 15 November), a thorough search was made to determina_.wha.t____ material is stiii available in departmental files regarding dust conditions during mining and milling operations at Wittenoom from 1943 to 1966. Although some important files were destroyed several years ago, in accordance with the authorized practice for defunct files, much information is still preserved on files held in the Mines Department and others previously held in Kalgoorlie and Karratha. Relevant material has been summarized in the attached report -- gg ^ /'P-o- The files record attempts by Australian Blue Asbestos Ltd to control dust in thfe mine and treatment plant throughout the history of the Wittenoom,operation. Attention was first drawn to the dust menace by a Mines Department inspector in 1946, and over the ensuing years there were repeated directions by inspectors, warnings by the Public Health Department, and complaints by workmen and their unions. In hindsight, it is difficuilt to understand how the situation could have been allowed to continue; however it must be remembered that Wittenobm was then one of the few mining operations in the State outside the Goldfields, and it was heavily subsidized, if a decision had been made to close the mine it is most unlikely that this action would have received support, from either the general pgblic or the miners, as few would have believed that the health situation was sufficiently serious. The company had threatened on at least one occasion (in 1962) that because . of demands being made by the Mines Department for improved dust-control equipment, and in view of the low profitability of the operation, the mine might have to' close. As discussed with you recently, it is a matter of serious concern to this Department that when legal representatives of a person who contracted mesothelioma after working at Wittenoom requested access to relevant files, they were informed that all the files had been destroyed. Furthermore, the same incorrect response was given in answers to parliamentary questions on 2 May and 10 May 1979. & PLAINTIFFS EXHIBIT IZ7&0 WV-04459 6/ i. You have indicated the need for a statement to be made to Parliament correcting the previous answers to parliamentary questions and advising of the course of action now being taken by the Department. A draft----" T statement with this objective is submitted for your cons-ideratioo. --It would seem inappropriate -to ineUflte-* ----opinions regarding blame for the Wittenoom situation in this statement, as the matter is sub judice. PEP:DRK:PS AA757m388 * SYNOPSES OF RELEVANT FILES ON WTTTENOOM File 1248/84 Australian Blue Asbestos Limited District Inspector of Mines .3. .22. Progress report by Inspector of Mines, Cue on the setting up of the mine, dated 9 June 1944. Repott by the District Inspector "ok Mines dated 17 September 1946. He draws attention to the "terrific" dust problem at the plant. "In any dry crushing plant the dust menace must be accepted as a major principle of design, not as an after thought." f.27. .. 1 Letter dated 15 November 1948 addressed to the Workmen's Inspector from the Inspector of Mines stating that although a new mill is to be erected at the mine "in which adequate provision is to be made for dust prevention, the men are fully justified in their.concern about conditions which now.exist.. CCndi.tions are definitely bad,. You ' *wt>ui<3 be within'ydur rights in pressing for . improvement to .the existing plant." This was" in response to a letter of complaint from the AWii., f.28. 14 November 1949 letter from the Acting State Mining Engineer addressed to the District Inspector of Mines at Cue informing him of the Workmen's Inspector's report on bad conditions underground, in the changerooms, and in the mill, and asking the DIM to investigate. f.30. Letter dated 18 November 1949 to the Workmen's Inspector from the Inspector of Mines "you should go to the mine as soon as convenient and inform the manager that continued breaches of the Act are likely to lead to prosecution." f.34. Letter from the Acting SIM to the DIM at Cue (Mr Boyland) dated 6 February 1950 referring to the Workmen's Inspector's report on bad conditions at the mill and also referring to a letter received from the Department of Health "in which reference is made to the danger to health that exists in this plant." f.36. Handwritten copy of letter (undated but known from the reply to have been dated 14 February 1950) from DIM, Cue to Manager, Australian Blue Asbestos, stating that "the continued dusty conditions are detrimental to the health of employees." Further that "3 now reauest that the milling section be totally enclosed by walls and that suitable dust extractors be placed in the roof." ,* 2. f .r?. Letter from the DIM, Cue to the State Mining Engineer dated 14 February 1950 referring to a visit to the mine and to the above letter. He found conditions generally satisfactory but expected the plant to be dusty for one reason or another and that he had written "to tbe~TXJmpa7iy"w asking that the mill be totally enclosed and that exhaust dust collectors be installed. f .47. Letter dated 17 February 1950 from the manager to the District Inspector of Mines, Cue, in reply to his letter of 14 February written under. Section 22 requesting the company to totally enclose the plant. In the letter the manager said to he was going to improve the dust collection equipment but objected to enclosing the plant on the grounds that it would make it hotter. f .49 . Letter from the District Inspector dated 24 April - , 1950. addressed to the manager* referring to.sra inspection where he`found that "the underground ventilation was somewhat backward." f .53. 19 June 1950 carbon of a letter to the SME from the District Inspector, Mr Boyland, advising him of the inspection where he closed down all the development faces except two because of bad ventilation. He seemed satisfied that matter will be put in hand to correct the underground and surrace problems with regard to ventilation. .65. 12 July 1951 copy of DIM Boyland's record book entry wherein he noted improvements in the milling and underground sections. f .77. 21 August 1951 Ventilation Report by Assistant Ventilation Inspector Faichney, The report details a considerable amount of short circuiting resulting in much reduced flows of air to the actual working places? also inefficient practices in distributing auxiliary ventilation air. Some improvement is noted in dust counts in the plant although the area in the vicinity is noted as being very dusty. He refers to the examinations of dust samples from underground and treatment and says that "the amount of fibre visible is very small." Tabulation of dust counts lists dust concentrations underground in the plant. Results range from about 100 to 800 particles per cc. 'S . f .80. 22 August 1951 copy oi a letter received from a Mt Alan Hume to the Senior Inspector of Mines in Kalgoorlie in which he complains that he was taken oft a machine because he would not let the bogger bog dry dirt. He was told by the foreman that water was bad for the fibre. He also reports that scraping from stopes was carried^gut wetting down. Mr Hume said he was sorry to have to bring the matter to the inspector's attention, but men's health was the most important consideration. f .83. f .84, 24 September 1951 letter to the manager from the District Inspector in Cue, Jack- Boyland, reguesting him to water down notwithstanding that he knows that the manager likes to keep the fibre dry. "Dust counts are relatively high and must be brought to a minimum." "1 know that it is your desire to keep the fibre as dry as possible, . however,this consideration must be given a low priority regarding the .health of. workers .. % A report to the Senior Inspector from the District Inspector, Cue, noting some improvement in watering down, dated the 24 September 1951. f .86. Copy of a letter dated 26 October 1951 from the Commissioner of Public Health addressed to the Under Secretary for Mines stating that "the upper permissible limit of asbestos dust for a working atmosphere is 176 particles per cc. It will be noted that many of the counts arc in excess of this.'1 The letter also points out the deficiencies of the konimeter as an instrument for sampling fibres. Reference is made to asbestosis causing a rapid fibrosis of the lung. In this respect "it is therefore apparent on the data submitted that conditions are far from satisfactory and in the interests of the health of the workers this Department must investigate the matter further and press for immediate improvement of supervision and working conditions at Wittenoom," This letter was duly sent to the Senior Inspector of Mines on the 31 October 1951. He then sent it on to the District Inspector of Mines at Cue. f .140. Letter il June 1955 from the District Inspector of Mines, Cue addressed to the State Mining Engineer referring to an inspection carried out on June 1. He "had occasion to draw the attention of the management to the very unsatisfactory working conditions in the milling section." "No effective modifications aimed at the eradication of dust had A. been achieved during the eleven months since my initial inspection. " Unless plans for improvement were forthcoming by the end of June the DIM would close the mill. Conditions underground were apparently "as good as X have seen." f .141. Letter 21 June 19S5 to the District I-nsfer^or-grc*Cue from the manager reporting work* carried out in the plant to improve ventilation. Acknowledged by minute from DIM dated 24 June 1955 (.142). f .163. Letter dated 24 October 19 56 addressed to the District Inspector of Mines, Mr Ibbotson from Mr Crawford, the AWU rep. complaining about smoke and fumes after firing underground. f .172 Letter 11 January 1957 to the State Mining Engineer from the District Inspector of Mines, Cue. Reference is made to "conditions throughout the mill were, very poor," and thatimmediate action was: require to. ensure, a better system of . dust control." * .192 Letter 8 March 1958 addressed to "Alan" from "Jack"; reference is made to repeated assurances by the manager that "everything will be put in order as regards to dust nuisance in the mill." However the writer does not think much of these assurances, and states that "Conditions as I see iz are very little better than they ever were.*' .193. Letter dated 5 March 1958 addressed to Mr Hunt, Workmen's Inspector, from the AWU rep., Mr Keen, complaining about dust nuisance in the mill, and stating that the situation is getting worse. .194. Letter from the DIM, Cue to the SIM, KaXgoorlie dated 17 March 1958 wherein it is stated that Workmen's inspector of Mines Hunt had pointed out that he was in agreement with the union rep's . sentiments. .195. Letter addressed to the manager, Wittcnoom from the DIM, Cue dated March 26, 1958 wherein a number of points in respect of dust problems in the plant are mentioned, and measures required to rectify the situation are outlined. f.200. Letter dated 2 March 1958 addressed to the "District Hines Inspector" from J, Fletcher, representative of the AEU. The letter is long and detailed and complains about the dust conditions prevailing in the mill. "In spite of repeated appeals to the management to have this constant fault remedied we have failed in every O nn T> 11 r- *' 5. f .202. Letter to Manager, ABA, <5 a ted 26 March 19 5 8 frois DIM, Cue outlining strict measures required to alleviate the dust problem at Wittenoom. f .207. Letter dated 3 April 1958 addressed to the Senior Inspector of Mines from the District Inspector, Alan Xbbotson describing an unannounced approach to Wittenoom, in order to avoid /orewarninc ^ ^ ^ management, followed by an inspectign which found conditions to be "particularly good." f.214. Letter to the SIM, Kalgoorlie from the DIM, Cue dated 22 May 1958 referring to an inspection made on the 21 May of mine and mill and explaining why he felt it necessary for his visit to be unannounced. f .216. Letter to the manager from the DIM, Cue dated 22 May 1958 complimenting him on the conditions in the mill. .228.> Letter addressedto; the State Mining Engineer from the DIM., Cue dated 22, October 1*9.58 The history of his inspections at Wittenoom is outlined, beginning with his first visit In July 1954, when he "was staggered to see the extremely bad working conditions in the milling section." Poliowing representations from workmen a Board ofc Reference was constituted and it was agreed that employees who had to work in dusty conditions would receive penalty rates. *1 was not at ail in favour of this, and Regulation 150 does not permit work to be performed in excessively dusty places. 1 told the manager that I would enforce this Regulation whether or not the employees were prepared to accept penalty rates." On his most recent visit the plant "was polluted with dust". He describes a temporary unit that had been installed consisting of screen mesh set on four 44-gallon drums and a small hammer mill. This unit was giving off clouds of dust which "was at liberty to penetrate the entire building." He stated his intention to restrict production if conditions ace not improved. f .229. Letter from State Mining Engineer to the District Inspector dated 5 November 1958. There is no reference to the DIK's proposal to restrict production. f.234. better from DIM, Cue to Manager, Wittenoom dated April 1959 regarding allegations by the union of "window dressing" by the company for inspector's visits, and the unauthorized practice of Sunday work. 3 f .2 67.

It states that the new plant is kept in ''spotless condition*, although for no apparent reason dust counts were "above average". Reference,.w the unsuitability of the Watson konimeter for asbestos measurements, and it is pointed out that dust exhausted from the mill enters the u nd e rg round working s. f.278. Report to the Senior Inspector of Mines, Kaigoorli from Simmons dated 22 July 1960 including tabulation of dust counts for the plant and for the mine, and a ventilation plan. Stated that action was necessary to prevent dust from the mill entering the mine workings. f .279. Letter to the DIM, Cue from SIM dated 17 August 19.60 referring ..to the comparison.-of a midget ' impinger and the konimeter for sampling dust in the mine. f.280. Copy of the Record Book entry to Manager, ABA, 6 September 1960, signed by the Senior Inspector and Workmen's Inspector "dust from the mill exhaust is interfering with the general ventilation and thus must be stopped." This refers to dust being sucked into the mine ventilation system. f.286. Report to the SIM, Kalgoorlie from Simmons dated 15 September i960 comparing particle and fibre counts taken by the konimeter and the impinger. Asbestos fibres 10-40 microns were counted. They were very few. Dust counts on the other hand varied from 200 to 1000 plus. The average of all the konimeter samples was 620 particles per cc whereas the average of the impinger samples was 451 particles per cc. The impinger collected an average of 2-1/2 fibres per cc while the konimeter collected an average of 1 fibre per cc. f.288. Letter to the manager from the SIM dated 19 September 1960 drawing attention to contamination of intake air by bins on the conveyor, also to dust from the plant going into the mine workings. f.293. Letter to the SHE dated 19 September 1960 from the SIM referring to Simmons' inspection and also the SIM's inspection, which apparently resulted from a complaint regarding Simmons by the mine manager. Reference is also made to airborne dust from the tailings dump being sucked into the mine '. "The comparison of dust counts with those taken during previous inspections should be humiliating to the 7. f.294. Letter from SIM to DIM, Coe.dated 3 October I960 referring to the above ventilation inspection, and exhorting the DIM to greater efforts to try to do something about the ventilation. f.317. Letter to the manager dated 20 December..-19 60 .f.ron^_ the Senior Inspector giving detailed recommendations with respect to the provision of adequate ventilation underground? also referring to continuing unsatisfactory dust counts at the treatment plant. Attached are tabulation of dust; counts which generally are quite moderate. However, dust* counts in the mill were still "far too high*'. "Will you please give all these matters your immediate attention". File 1249/64 ( .. Australian 8iue Asbestos, Ltd District Inspector of Mines Correspondehce, Voi. 2*. # ' f. 17. Ventilation Report for August 1961 dated 15 September 1961 to the Senior Inspector from Simmons, District Inspector of Mines Ventilation. Also attached are tabulations of dust counts referring to underground and surface. There are a great many 1000 plus particles per cc samples. The report complains about inadequate air flows, even non-existent in some places. Also accompanying the monthly report is a report to the Senior Inspector dated 10 September 1961 giving average dust counts in the plant for previous months to June 1960, showing that the August 1961 figure (630 particles/cc) was the highest. f.25. Letter to the manager from the District Inspector of Mines , Ventilation dated 9 October 1961 "much dust was found to be entering the mine through the main adit. Counts of 1000 plus, 960, 370, 250, 150 particles per cc were recorded." The mine air appeared much more dust laden during this inspection than any previous inspection." .28. Letter to the manager dated 6 November 1961 from the Senior Inspector of Mines "medical examinations of workers who either are employed or have been employed on your properties at Wittenoom have shown that a dangerous dust menace is present." The letter also contains a directive under Section 22 "to eradicate the dust menace" i and under Regulation 150 to the effect that air water jets must be used underground and that 8. callings etc. must be sprayed. Reference is also made to 'dust escaping from the plant which re enters it and also enters the mine workings. Unless something is done about it "I will be reluctantly compelled to take the necessary action to prevent men being exposed to unhealthy conditions. '* "Dust, prevalent iff'yoarr'^uTtfiq'^nd Milling Sections, threatens.. .the bbdily injury of persons. " f .30. Record Book entry dated 27 October 1961 signed by the Workmen's Inspector and the DIM, Cue reference is made to dust escaping in various parts of the plant. f .34. Letter dated 20 November 1961 to the Senior Inspector from the mine manager referring to the "dust menace" at Wittenoom. This is in reply to the Senior Inspector's Section 22 etc. letter and says that actions are being taken, to improve conditionsThey "realize the seriousness of the position...we will do everything we possibly can do to reduce the dust to a minimum." f .37. 6 December 1961 copy of a letter signed by DIM Ibbotson "because o the highly dangerous nature of the asbestos dust", he instructs the manager to reduce production to an equivalent of 14,000 tons per fortnight. .38. Letter dated 7 December 1961 from the manager to the DIM notifying that an appeal against the above letter would be made. f .46. Report addressed to the DIM Ventilation from Assistant Inspector of Mines Loxton dated 29 December 1961. The report refers to an inspection of the ABA mine and quotes dust counts made during that inspection in the main adit of 240 particles per cc which is an appreciable drop from the figure obtained in October when it was 480 particles per cc. Conditions in the mill were said to be "critical" wi^h average dust counts of between 330 and 620 particles per cc. "Much fibre was noticed in the samples." f .48. 4 March 1962. Letter from DIM, Port Hedland. It appears that genuine efforts are being made by ABA to alleviate the dust problem. 9. f .62. 6 April 1962. .Report to SIM by DIM (Venci.. Kalgoorlie. Conditions appear better than before, although "some asbestos was seen in the underground samples, whereas much fibre was seen in the mill samples.*' "The Management are definitely trying to control the dust and are spending much money on it, but owing to increased through-put, and the inability o- the^pr^&ont-dwrtcollection system to handle it, success seems highly improbable." .64. Minute from SIM to SMB dated 11 April 1962. "I cannot agree with Inspector Simmons. I fail to see total and concerted effort on the part of Management and the Supervisors in the matter of improving (dust) conditions." Dust counts ranged up to 1000 plus in three areas. f.79. ; 17 July 1962. Report to SMB by DIM, Kalgoorlie, Simmons.*"Conditions throughout the mine from the' dust angle would be at their worst, in fact, the average co.unt.for day shift is the highest ever." "Some asbestos was seen in all -underground samples and much fibre was seen in the treatment plant samples." "Good cooperation still exists between us and the mine personnel, but it is felt more positive action could be taken with the various projects and problems." .81. Minute to the SHE from the Senior Inspector dated 20 July 1962. "The overall dust counts at Australian Blue Asbestos are the worst I have seen". "I am without doubt losing patience with this Company. All our inspectors have gone out of their way to offer assistance to this mine and I am beginning to think that this has been taken as a sign o weakness. All kinds of promises have been made by the Management but very few fulfilled. Inspector Ibbotson and myself both feel that we have reached the stage when we are afraid that our personal disgust could cloud reasonable unbiased interpretation. I have already told the manager that if he does not fulfil his obligations, I personally will initiate prosecutions against him. 1 must await the results of the present dust collecting tests, but if they are not successful, or if they are successful and work (is) not put in hand to immediately rectify all defects I will be both morally and duty bound to close the mine." 10 . t. 83. f .84. Letter to the manager, Wittenoom from the SIM, Kalgooriie, dated 20 July 1962 advising that in future when an inspector found dust problems he would stop the work or the appliance as appropriate. Minute to the DIM from the SIM dated 20*June wherein the DIM is offered "full backing" for any action he may see fit to take. "After digesting all figures 1 can only conclude that the Management is too complacently self satisfied and that the Ventilation Officer knows absolutely nothing about ventilation." f .105. Minute to the SME from the DIM Port Hedland dated 14 September 1962 referring to an inspection carried out on the 12 and 13 September. The DIM cites some improvements but is still not at all satisfied. He comments that the majority of miners, do not seem -to understand- the ne.ed for- . ' watering down and top th use of ventilation equipment. "As far as they are concerned time spent iH attending to these tasks does not earn them any money, and money is their only concern.'' He said that a majority of the work force will make no attempt to minimise dust. .107. Minute to the Senior Inspector from the District Inspector of the 9 October 1962 advising that the mining company is increasing production witnout reference to him notwithstanding his requirement that they limit output to 14,000 tons per fortnight. "1 do consider that we still have a major problem with excessive dust...each time the output from the mill is raised we can expect a corresponding deterioration of the working conditions.* f .108. f.110 . Report to the Senior Inspector from the District Inspector dated the 13 October 1962 wherein again reference is made to increasing production and the effect this will have by increasing the amount of d*st in the mill. Letter from the manager to the DIM, Port Hedland dated 12 October 1962 wherein are quoted tons milled. All figures are below the 14,000 tons limit. f .124. Letter to the Manager dated the 15 January 1963 from DIM Ventilation Simmons. He advises that the dust levels of samples taken in the mill were even greater than those taken previously in June 1962, when they were the highest ever recorded. They raneed from 715 to 950 po/oc- XI. f .129 . A letter from Dr McNulty to Acting State Mining Engineer Boyland dated the 8 March 1963, enclosing a reprint of his report on the first mesothelioma detected in an asbestos worker in W.A. The miner concerned worked at the Wittenoom mill from 1948 to 1950. ___ . , t .161. Minute addressed to the Senior Inspector from the District Inspector, Port Hediand dated 21 January 1964, asking for backing in the implementation of some regulations with respect to measures required to diminish dust, which is of "known toxic" nature. f .163. Reply to the District Inspector from the Senior Inspector dated 28 January promising full co operation. .170. Minute to the Senior Inspector from the District Inspector dated 25 .February 1964 reporting .that tailings were being treated and that the mill was in a "shocking condition*'.' No attempt had been made to dampen the feed material. f.211. Letter addressed to Xbbotson, District Inspector of Mines, Port Hediand from Dr McNulty, dated 30 November 1964 stating in response to an enquiry made by Mr Xbbotson that the use of asbestos mine tailings for road surfacing around Marble Bar must cease. He says that ir there is any difficulty in stopping the Shire Council the DIM should advise the writer who could then take action under the Health Act. f .212. Letter dated 5 December 1964 from DIM Xbbotson to the District Engineer, Main Roads Department, Carnarvon, pointing out that Australian Blue Asbestos has ignored advice of the highly toxic nature of,asbestos, and that asbestos tailings were still being used as road-building material, including indiscriminant use around Wittenoom itself. f .215 Minute addressed to the State Mining Engineer, 5 January 1967 referring to the closure of the mine on the 30 December 1966. 12 .

Letter from ABA to the Premier dated 23 November 1962 requesting Government assistance, and reporting that in 19 years of operation' the mining company had only paid one dividend of 7%. "Because of the possible health hazard we are now being pressed to replace our dust-collection equipment with a more efficient installation at a cost of 120,000. Coming at this time we must consider whether or not such a major and non profit earning expense is justified considering the poor profit record of Australian Blue Asbestos Pty Ltd or whether it would be better to close the mine down. The main consideration against closing is that...the operation can be economic." The company requested the Government to arrange a direct shipping service from Point Samson to east coast ports and a subsidy for diamond drilling costs of up to 30,000 per annum. Such assistance would be needed for a break-even basis of operations, and the company would then be able to make the "exceptional capital expenditure of 150,000 for dust collectors and amenities in the town," f. 107. The Hon. Premier wrote to the Prime Minister supporting the proposal of a direct shipping service to the east coast, and agreeing to the 30,000 p.a. drilling subsidy for each of two years.

One development end was found to have a 1,000 plus particles per cc. Dust conditions in the plant "most unsatisfactory" with three out of seven dust counts at 1,000 plus. The manager was informed of the health danger4to the men. The manager responded that the present plant would be replaced after sufficient data were obtained from the present operation. f.23. Report dated 13 October 1950 addressed to the SME from the same District Inspector. The report details temperatures and airflows underground. Dust in the treatment plant had "definitely worsened." Out of 12 samples in the plant 8 were at 1,000 plus particles per cc with the lowest at 410 particles per cc, in the dining room 1,000 particles per cc. The samples were viewed through the microscope by the management. f-38. Ventilation report dated 12 December 1958 addressed to District Inspector Faichney in Kaigoorlie from E.F. Shenton, Assistant Inspector of Mines "dust counts recorded in the underground workings were in general satisfactorily low." "Considerable.amount of dust was being injected from this stack...picked up by air current in the gorge which could move the dust into the cliff openings of the mine." Tabulation of dust counts are attached. "In the Wittenoom mill conditions appeared dusty, but no high counts were recorded. It is possible that the intake jet of the Konimeter may have become choked by fibre.

"men's health is more than just a bit of time to dry out a bit of fibre outside," Report dated 24 September 1951 addressed to the Senior Inspector of Mines from Boyland, DIM. Reference is made to a complaint, apparently about the lack of water used for dust suppression. Minute addressed to the SME from Paichney, Assistant Ventilation Inspector dated 2 November 1951. He refers to the SME's letter 818/51 which carried the advice that the "upper permissible limit for asbestos dust for working atmosphere was 176 particles per cc." The limit for silica dust is 300 particles per cc. He notes the Commissioner for Public Health's objection to the koniraeter on the grounds that it probably excludes long fibres and suggests that use should be made of sugar or cotton wool or a gravimetric method using a filter paper to collect dust. "The enforcement of the use of plenty of water in the mine and the consequent need for a ibre-'drying process in the treatment plant is an urgent necessity." 18. .59. f.6G. .65. f.73.
