January 22-23, 1997

 

Joseph Fitzgerald: Opening remarks.

 

Ron Edmond: Ground rules.

 

Margaret Morrow: Deputy Vice President for Defense and Manufacturing for LMES: In my time at Y-12, about 30 years, we have dealt with beryllium (Be) and Be compounds. We have tried to make sure that we had standards in place and met those standards. Those standards have changed, and we have found that those standards are not adequate to protect workers. At LMES, we have taken the ALARA approach so that we can do everything we can to ensure that employees do not receive exposures while the standards are being evaluated. We welcome the chance to look at the standards and discuss what is appropriate. We will support the work in looking at the health studies, dealing with persons who have worked with or around Be. We will provide you with any technical information that is required. We will submit a separate written document with a number of details about the technical aspects of Be exposure at the Y-12 Plant Site. We embrace the opportunity to go into an open forum and to look for answers about what we need to do to make sure that persons who work around Be can do so ensured that their health is not in jeopardy. We have set up a number of initiatives for those persons on our site who have been diagnosed with CBD. We will continue to support those persons with CBD.

 

David Weitzman: The ALARA approach--will your documentation describe in a practical way what that means?

 

Morrow: One of the things I have been charged with at the Y-12 site is to form a team to design what an ideal facility would look like. We have taken some extraordinary means to look at that.

 

Fitzgerald: Has it been difficult to identify the Be worker population?

 

Morrow: No. Over the plant’s history, a large number of facilities have housed Be. But we have a very good system to identify where and with what people have worked over the years. Everyone at the plant has been given the opportunity to write in and tell us if they think they have ever worked around Be. When it comes to exposure, we recognize that sensitivities vary.

 

Kevin Sikora: What would you recommend for a new exposure limit?

 

Morrow: I believe the current exposure limit is not adequate because we have a number of people on our site who have come up with positive tests on CBD, even though we’ve designed our facilities to keep exposures below the PEL. I think we need to look at the current standard. That’s where the ALARA comes in. What can you reasonably achieve with administrative controls, engineering controls, and PPE? We have to understand the technical basis for the current standard and then look to see what we need to do.

 

Fitzgerald: Are there any current operational issues, any active work involving Be where you’ve been applying ALARA?

 

Morrow: Yes, over the years, for operations where we felt the chance for exposures was high, we have taken precautions to put in special ventilation systems, air flow systems, so workers have to rely on respirators only as a last line of defense. We’re not currently doing much Be work. But, as we look at the future, we do see the need for some of the Be activity to start up again.

 

Fitzgerald: Have you outlined D&D areas?

 

Morrow: We have identified, to the best of our knowledge, areas where Be has been processed, handled, or stored.

 

Fitzgerald: What would be the ALARA approach to releasing an area for D&D?

 

Morrow: There’s significant potential for exposure when D&D activities start to occur, and it’s not only Be. You really have to do a survey and meet the requirements to see that you have the right engineering controls and PPE in place. Until you can get a good idea about how contaminated an area is, one has to go on the assumption that you go to the extreme and use all of the protective measures.

 

Weitzman: Please provide cost information associated with the various control measures.

 

Morrow: We can give you some sense of where controls have changed and what it cost. It may be difficult because of the organizational budget.

 

Jackie Rogers: You mentioned initiatives you’ve set up for individuals with CBD. Please provide details in your written comments.

 

Morrow: There are not many added costs. There are no costs to the employees.

 

Fitzgerald: Medical removal--it would be useful to get a perspective on current Y-12 policy.

 

Lou Nadeau: The "reasonable" in ALARA points to economic costs. Can you discuss the method for determining what is reasonable?

 

Morrow: I don’t think we know enough about Be sensitivity to do that at this point. How do you make that judgment? We will provide to DOE what the costs are, and if they want to continue work in this area, that’s what would be prudent costs.

 

Sikora: Please give details on the effectiveness of engineering controls.

 

Morrow: Where we’ve changed controls, we can provide you with the information.

 

---------------

 

Gary Foster: (SEE WRITTEN STATEMENT)

 

Fitzgerald: Given your considerable research and personal experience, what is your opinion on an appropriate exposure limit?

 

Foster: Zero. 0.1 has been shown to be associated with CBD in the "neighborhood cases." 0.17 was the mean concentration at Y-12 between 1960 and 1980, when there were confirmed cases of CBD. In my written comments, I make reference to a detection method that gets down to 0.0039.

 

Weitzman: Are you also going to recommend other suggested controls? (Tape ran out)

 

Foster: Those will require extreme rigor. The service personnel are not really controlled administratively in the plenums and the basements where Be settles out.

 

---------------

 

Rusty Stiles, CIH at Rocky Flats: Provided information about what’s happening at RF. They have two efforts: the first is a site Be characterization. We have 70 cases of CBD and 127 people who are sensitized. Of those with CBD, 19 are machinists, 6 are secretarial/clerical, 5 are engineers, etc. We know that, within 2 to 5 years, sensitized people have been developing CBD. He showed a map of Be locations at RF: the 400 area, machining; the 800 area, analytical work; and the 700 areas, specialized processing. In some of these areas, we don’t know why people have contracted CBD, because we thought the buildings were clean. The second effort is an applied industrial hygiene survey (Kaiser Hill and Radian Corporation). These are some of the considerations in justifying the characterizations:

* CBD cases are rapidly increasing.

* Want to continue medical surveillance program.

* Want to appropriately characterize facilities.

* Want to manage D&D to deal with Be contamination in the smartest way.

* Want to design effective controls.

* Want to sample all Be facilities, but can’t afford everything, so we’re developing a sampling strategy.

 

We have five project phases: (1) work planning and management, (2) sampling, (3) Be management plan, (4) Be characterization report, (5) database development.

 

We have a lot of information about the facilities where there’s a high probability of Be contamination, and we have some information about moderate probability facilities. But, we don’t have much information about facilities where the probability of Be contamination is low, yet we’re finding people in those facilities who are becoming sensitized.

 

We are using personal, area, surface, and particle size characterization monitoring. At RF, we have an HSP, which mainly says to keep Be levels as low as possible; the number we use is 25 mg/ft2. That’s not cutting it because people are still becoming sensitized. So, we’re going to take some bulk samples and do particle size characterization. The analytical method we’ll use is ICP mass spectrometry, which we feel gives us the lowest limit of detection. An interesting question involves the size of the particles and how that relates to inhalation and deposition in the lung.

 

We currently use 0.5 mg/m3 at RF as an action level. We’ve been doing that since 1989. It’s an administrative standard that we’ve come up with. But even with lowering it to 0.5, we’re still having people develop CBD.

 

We’ll be characterizing 35 buildings. Then, a site management plan, site characterization report, and computer database will follow. We should have final product by September. We’re hoping for new or improved protection criteria, new or improved release criteria, stratification of relative risk by facility, streamlined safety costs for D&D, and an information link to medical surveillance.

 

We thought about putting warning labels on equipment. But when you look at toxic tort and liability, warning labels don’t buy you any exemption from litigation. So, the label has to say the right things.

 

Fitzgerald: Would you characterize this as RF’s version of ALARA? You mentioned cost as being a restraint. I’m just curious about how you make the judgment about how far to go; what is reasonable?

 

Stiles: If this were an ideal world, we’d have an unlimited budget. But that’s not reality. We have a very good group of construction engineers who specialize in demolition. Our recommendations have to be reasonable or we’ll never bring anything down. We could spend billions of dollars and not bring any buildings down. We’re focusing on areas where there’s a low probability of contamination. The goal here is future cleanup; we can’t do anything about the past. We know the high and moderate probability areas where we have controls in place; do we need to ramp those up? What’s the appropriate level of protection for people who’ll be coming in as outside contractors to demolish these buildings? Do we put people in supplied air line? All of these will drive up costs.

 

Doug Allen: It’s a challenge to determine where we want to take samples. We want to focus most of our sampling on the more clean levels to demonstrate with some confidence that those areas are free of contamination. This requires a fair amount of sampling. Within a building, it’s not just rooms; it’s shared ventilation systems and common shared air spaces above ceiling tiles. We are putting together a work plan to delineate where we need to take samples. In the more dirty areas, we’re focusing on equipment that might be made available for release. The other part of our strategy is a combination of random sampling and biased sampling. We identify areas in the building where we think contamination is most likely to occur (the biased areas) and then randomly select facilities for sampling.

 

Fitzgerald: Is it really feasible to rule areas as low probability vs. high probability when you’re getting into selective dismantlement?

 

Stiles: It’s not going to be easy, but we will document a stratified decision about what is high, moderate, and low. (Talked about all the contractors and subcontractors involved in work at Rocky Flats.) The first building for characterization is the DOE Field Office, which is supposedly clean. The next building will be 776, which will be characterized during the next 60 days. We’re not just looking at Be; we also have also radiation component and asbestos--we’re doing a complete characterization so you as the project manager will know what to expect. Radian is focusing on the slice of the pie dealing with Be.

 

Fitzgerald: How does training fit into your operations and practices (particularly with the subcontractors on site)?

 

Stiles: We have a computer-based training course dealing with Be operations. Everyone who’s going to be working with Be in any shape, form, or fashion goes through that course. Also, we have a H&S procedure on Be. Neither one is magic, but it gives an awareness of how to work with Be and where to get information. These procedures are going to have to be modified for D&D operations. We don’t want to have to put people in arduous PPE if we don’t have to. But, we might have to work it just like an asbestos job.

 

Fitzgerald: Will you be doing real-time operational monitoring?

 

Stiles: Yes.

 

Fitzgerald: Are you reconsidering your action limit?

 

Stiles: Yes. We don’t have any data to give now. It’s a difficult question when dealing with releasing equipment. It’s hard to get equipment completely clean. The question becomes: where is this equipment slated to go? To another DOE facility? To general auction?

 

Allen: This is a baseline characterization effort. What will come out of this will not be complete enough to turn loose demolition teams. Rather, it will allow us to give better instructions on how to characterize the building for demolition.

 

Fitzgerald: Asked for more information about medical monitoring in submittal.

 

Stiles: That will be the proof of the pudding. I’ve never been a Be worker, but I’ve been through a lot of the areas. I recently had medical surveillance for sensitization; I don’t know the results yet. At RF, there’s an extremely high turnover rate of employees. We have reams, a trailer full, of Be monitoring data--file cabinets full of personal and surface samples. We have additional reams of data at the Federal center. The problem is that many of those folks are gone and many who put the data together are gone. I’ve been tasked with pulling all this together in one place; it’s an overwhelming task. We are asking for additional funding to collate all the information and organize it.

 

Weitzman: What are you using as the level of detectability?

 

Stiles: Here’s the recommendation from the ES&H Steering Committee. One group recommended 9 mg/ft2 to release equipment and facilities; model for that was taken from the Pinellas facility. Because of the unknown dose response, we recommended nondetectable by ICP mass spec. This is not yet resolved. I think 0.05 mg/filter is the level of detection for ICP for an air sample.

 

Allen: There’s no correlation really between surface swiping and air monitoring.

 

Stiles: Absolutely none. We just use surface monitoring to determine presence.

 

Sikora: You indicated that 25 mg/ft2 was not good enough because people are being sensitized. Do you have wipe sampling data for low-probability facilities?

 

Stiles: We do have some, and some are below 25.

 

Kevin: What type of activities will get personal monitoring?

 

Stiles: Various activities: cleaning, radcon, packaging up equipment, dismantling the building (from HVAC systems to knocking down the walls). Funding for the characterization ends in September.

 

Kevin: Is this site characterization effort something you would consider reasonable to require for any D&D operation?

 

Stiles: It’s definitely not a Cadillac program. I would hope that the information we get could be used in preparing for other D&D projects. If you’re going to work on a building at Y-12, we could say "Here’s what we learned at Rocky" and it may be of help. What we may find is that, even though we offer the maximum controls we can, there’s still a risk associated with that. We may not be able to totally guarantee that you won’t become sensitized. When we’ve done the best we can do, there still is a risk. At that time, people who work in that industry have to decide do they want to continue.

 

Fitzgerald: What guidance would you see as being of value for the Department?

 

Stiles: Emphasize to your contractors and subcontractors that you expect them to take the Be portion of the work very seriously. It’s paramount that people take this sampling as part of the hazard assessment very seriously. With regard to a hard-and-fast number, if you’re going to come up with an airborne standard, I would at least go down to 0.5. I don’t know how much that’s going to buy us, but I do know we’re able to control it to that level.

 

Fitzgerald: You mentioned affordability. What are the cost comparisons for 9 mg/ft2 as opposed to the limit of detectability? (Tape ran out)

 

Stiles: I don’t want to give a figure, but I can share a philosophy. Anytime you make control more stringent to bring the levels down, the price will definitely go up. There are tremendous costs for controls until the technology matures. (For example, an asbestos job that cost half a million dollars ten years ago, costs $30,000 now.)

 

Allen: Talked about the extra risks to the worker from the stress of additional PPE (exertion, overheating).

 

Weitzman: There’s clearly a point of view that the CBD cases resulted from overexposures that just weren’t measured. Is that your conclusion, or is your analysis that people are getting disease from lower exposures?

 

Stiles: It would be an oversimplification to suggest that if we took IH air samples that we could use them as the sole criteria for judging how people got the disease. I can give you some scuttlebutt with regard to things I’ve heard about machinists who worked without respirators and ate in their areas because they were told that there wasn’t anything to worry about. We’ve had some anomalies, things like Be being tracked into non-Be parts of the building. We don’t know what the dose-response is. We don’t know all the factors. We also have some new employees who have never worked at Rocky Flats but who are sensitized.

 

Dwayne H______, RF: In any future Be operations, from our experience at RF, I would suggest limiting the number of individuals working in that operation. You should have separate ventilation systems. You should limit the number of areas where Be is handled. The fact that we have Be sensitization in a reporter who was allowed to go through a Be area is ludicrous. With regard to David’s question, I want to talk about two individuals working at RF. One was a secretary working in Building 91, a very low probability risk area. She was hired in 1952, worked there for a year, and never went into a Be shop. We know that Be billets were stored in the hallway covered in plastic. She left the plant site in 1953 and 10-12 years later started to suffer from a chronic respiratory condition. In 1995, we found her in Florida, and she was diagnosed with CBD. In her case, exposure was probably extraordinarily minimal. We have another secretary, hired in 1988 and left in 1994, who is now sensitized. During her last 2 years of employment, her job was to pull charts and building plans out of old files. It’s hard to believe she came anywhere close to 2 mg/m3.

Donna Cragle, ORISE: ORISE has been conducting a study in Oak Ridge since 1991. The primary objective is to determine the prevalence of CBD in former Be workers at Y-12. At the beginning, we thought there might not be any cases at Y-12. But, by the time we started our study, we knew of one case that had been diagnosed by an outside physician. We also wanted to look at the usefulness of LPT in detecting the disease. We also wanted to look at the level of sensitization in the population and the various factors (form of the Be, specific job tasks, etc.).

The estimate of 4121 Be workers was compiled from a number of sources.

(REMAINDER OF THE PRESENTATION CLOSELY FOLLOWED HER VIEWGRAPHS)

The information about individuals’ exposure frequency and the number of hours they worked with Be was collected via the questionnaire (self-reported). They want to streamline the medical examination process; it has been taking an entire day per worker. But, in the future, it won’t involve going off-site. They also want to expand the study to include ONRL, K-25, and Mound workers (70 to 80 people at Mound have worked with Be).

 

Fitzgerald: Asked about the varieties of Be used and the effect on results.

 

Cragle: For all of the different types, including three classified types, we didn’t find any difference in sensitization rates. What did stand out was Be dust; that increased markedly.

 

Fitzgerald: Will the study be expanded to include non-Be workers?

 

Cragle: We felt we had an obligation to do the definite Be workers first. It could be expanded later. We don’t know of any CBD cases outside the Be worker population.

 

Weitzman: How were high, medium, and low defined for the people filling out the questionnaire?

 

Bill Tinkersly: We didn’t use those words on the questionnaire. They were asked about number of hours in a day, days in a week, weeks in a year that they worked with Be.

 

Weitzman: Asked about the validity of the small numbers.

 

Cragle: The numbers I showed you here are statistically significant.

 

Weitzman: Asked about the efficacy of the LPT.

 

Cragle: If their blood test was normal but their lung function was very poor, none of those so far have been diagnosed as having CBD. Of the people who had an abnormal blood test, about 50% were diagnosed as CBD.

 

Nadeau: Asked for cost estimates for the screening process.

 

Cragle: Will supply.

Mark Kolanz, ES&H Director for Brush Wellman: (SEE WRITTEN STATEMENT)

 

DOE priorities should be:

1. Provide resources for the development of a Be Manual.

2. Provide resources for the development of site-specific procedures and training at LANL.

3. Support research into:

-- Animal model for Be research

-- Improved treatment of CBD

-- Effects of particle size and chemical form on potency

4. Define Be use within the DOE (he had never heard of Be use at Pinellas until this meeting).

5. Extend comment period by 2 months (to allow for more economic analysis, etc.).

6. Focus limited resources on solving the problem rather than issuing a rule.

 

Sikora: Mentioned particle size determination. Does Brush Wellman do anything now?

 

Kolanz: We’ve not completed our studies. Most of the Tucson study data did not have a high level of statistical significance. The statistical significance so far has been for nonsymptomatic disease. We hope to get some link between particle size, particle characterization, and health effects.

 

Weitzman: Has Brush Wellman published data on health surveillance activities?

 

Kolanz: National Jewish Center did the studies. The Tucson report has been published; the Elmore report has not yet been published.

 

Sikora: What would you see as the critical elements of a DOE Manual?

 

Kolanz: I’ll be providing that in the written comments.

 

Weitzman: We’re particularly interested in how you approach ALARA—the more examples the better.

 

Kolanz: We’ll attempt to do that, especially if we have more time.

 

Fitzgerald: Asked about the use of mass spectrometry for determining low levels.

 

Kolanz: We use different methods, depending on what we know the experience is in the area (the analyte). We find that we can analyze a lot of our samples through flame atomic absorption, which has a 0.1 level of detectability. Often, it’s more important to get the results back quickly (20 minutes for flame atomic absorption). As for the level of detectability, I posed this question several years ago to a panel. They thought that anything below 0.05 would be in the fuzzy zone.

Bob Narvess, with Bechtel: Asked about remediation aspects at former DOE sites where workers are working in rapidly changing environments. Looking at contaminants on the Paynesville (?) site leads me to be concerned about toxicity levels and particle size distributions. That type of information should be disseminated among DOE contractors. We have information on the soil levels, and I am trying to gather information about whether any other subcontractors have this type of data. You’ve been talking about manufacturers working with pure Be, and we’re cleaning up what those manufacturers have left behind. I can give you the data we have.

 

Gary Foster: I’d like to say that there are two things in the Federal Register questions that I take exception with. They seem to be heavily weighted to smear sampling and the costs involved. The costs involved are externalities. DOE should remediate without complaining too much about the costs. I can’t find any literature that correlates smear sampling with air contamination. With the D&D work going on, you’re going to get into situations similar to the "neighborhood cases." You’ve got the population of Oak Ridge very near these buildings that are going to undergo D&D at Y-12. Air sampling is going to have to be done in the immediate area and at a radius out from the D&D.

 

David Kirby, IH, ORNL: Layton Cooke, IH at Y-12, has submitted information about the wipe sample technique that needs to be given some consideration. Most industrial hygienists agree that wipe sampling isn’t a good methodology for making these cut-point decisions. There’s wide variability with that technique. In this overall process of trying to decide what needs to be done, what’s really problematic is that there doesn’t seem to be a well-defined analytical process. No one seems to know which technique offers the best methodology. If we’re looking at putting this thing in a box, we have to come up with a standardized process for sampling and analysis. Without that, you’re putting the industrial hygienist and management in the position of making decisions without the proper tools. Maybe, we should put out a call to the technical folks about how best to do this. Other methods might give an idea of what is airborne; one of the methods we’ve used with asbestos in the past is micro-vacuum, which might equivocate what’s in the air. Another thing being used a lot in lead is X-ray diffraction; it could be used to give you some sort of surface determination.

 

Weitzman: Will you be recommending any methods?

 

Kirby: I've just started to get familiar with this issue; that’s why I’m here today. I’m going to try to go back on my own and talk to some of our technical people. I concur with the Brush Wellman spokesman that we may need more time. The Laboratory staff could probably suggest some new techniques.

 

Rusty Stiles: As for X-ray fluorescence, we thought about that too. But, where its a Conduct of Operations situation, that would be pretty hard to sell. I would love to bring X-ray fluorescence into our facility, but it would be difficult.

 

Kirby: All of these have pluses and minuses, but you may be able to lower your detection limit and turn-around time with a higher confidence level. There’s a tradeoff.

 

Kolanz: Comment on sampling strategy—don’t get caught up in trying to find the absolute perfect method. Choose the method that does the best for the process you’re trying to evaluate. I’ve used all different types (vacuum, wet swipe, etc.). If I’m stuck with one sampling method and can’t use it to improve the method, then I’m not doing my job. Leave it up to the professional IH at the site; they know best. If you have 25 sampling methods, just try to see that they are applied in a standardized way throughout the Department.

 

Fitzgerald: We’ll get back to you quickly about the determination of extending the comment period.

 

Thursday Morning

 

Dr. David Deubner, Corporate Medical Director, Brush Wellman: Addressed three issues: Medical Surveillance for CBD, CBD Experience and Be Exposures, and Beryllium Lung Exposures and Cancers.

 

Medical Surveillance: BW has conducted Be medical surveillance for decades, using quarterly symptom reviews, quarterly pulmonary function tests (forced vital capacity, forced expiratory volume, and CO diffusion capacity), and chest X-rays. Since 1992, BW has been conducting systematic epidemiological surveys (Analytic Medical Surveillance) with blood LPT and follow-up bronchoscopy (lavage and biopsy) to identify individuals with subclinical stages of CBD (i.e., no related symptoms). BLPT has a high variability in applications in terms of high inter-laboratory variability and high test-to-test variability. BW has used dual laboratory testing (split samples sent to two labs) to improve sensitivity with excellent results. Dual-lab testing significantly improves the detection rate of subclinical CBD. The exact sensitivity using single or dual lab testing is unknown. Since positive individuals may test positive on a given day, they may be missed by a survey. Some individuals who demonstrate clinical CBD on lavage may consistently test negative on the blood test. This is an example of immunologic compartmentalization. These individuals are also missed by a BLPT survey. The positive predictive value of a single positive LPT test is approximately 35% in a population with a 4% prevalence of CBD. The positive predictive value increases to over 50% when there are two positive LPT tests before sending someone to bronchoscopy. Our best estimate of the rate of positivity on BLPT in the general population using the traditional conservative cutpoints may be in the range of 1%.

 

The process of doing BLPT and then using bronchoscopy to make a diagnosis of subclinical CBD has value in identifying work processes associated with higher risk. Those results can be used to guide investment in prevention measures. To achieve that benefit, you have to enter the process with the determination to test people, gather information on work histories, and gather information on levels of exposures associated with job tasks. If you don’t do that going in, you won’t be able to use the results to identify high-risk processes.

 

The value to the individual employee participating in these surveys is mixed. The process of testing and bronchoscopy is frustrating due to the variability in the BLPT and the lack of clarity in the results (false positives, false negatives, etc.). People transition from perceiving themselves as healthy to perceiving themselves as ill. Job changes may be accompanied by perceived or real loss of security. Early treatment, the value of which has not been established, is accompanied by the medicalization of life and the potential occurrence of real or perceived disfiguring, morbid, or fatal treatment effects. Adoption of a dependent, victim-oriented psychological state is not infrequent and may be accompanied by severe psychological distress. One outcome of our planning is the preservation of freedom of choice for the individual and also detailed written and oral disclosure of the issues involved.

 

The epidemiologic value diminishes substantially and the opportunity for misinterpretation of survey results increases substantially as the population diminishes. Negative results may be incorrectly interpreted as absence of risk. Even if cases of subclinical CBD are detected, small numbers will not allow confident delineation of process-specific risk and therefore will not offer guidance for preventive intervention. When the population being surveyed is small, there’s a strong temptation to add to the numerator by adding in undiagnosed persons to the case category. This further adds to the difficulty in interpretation.

 

CBD Experience and Be Exposures. Since the beginning of efforts to understand Be lung disease, almost all observations of Be exposure have been made in terms of total airborne Be. We have evidence in hand to suggest that total airborne Be may not be the key to understanding Be exposures. The fact that duration of work with Be does not predict risk argues against simple models of accumulated total dose. At the Elmore plant, the higher-risk area identified in a major survey did not have the highest dose rate or the highest total airborne Be exposures. In fact, this area emerged as a high-rate area after BW and DOE spent a large amount of money to successfully reduce total airborne Be exposures in this area. In fact, the high rate of subclinical CBD shows up only in workers who were employed by Brush in this area after the exposure levels were markedly reduced. In recent years, estimated exposures of persons with newly identified subclinical CBD in terms of total airborne Be are not significantly greater than those of other workers.

 

This leads to the question: What is the key exposure characteristic that we should be measuring? BW has a study under way to identify particle size characteristics and chemical composition of airborne Be. This work will better delineate what fraction of Be in the air may be a better predictor of risk. We encourage other employers to do similar work. If we can better delineate what fraction of airborne Be is responsible, this would give us a much enhanced ability to create a more effective Be exposure standard.

 

Be and lung cancer: All who have looked at available evidence agree that, at current occupational exposure levels, Be does not constitute a significant lung cancer hazard. Debate continues about whether the small excess of lung cancer in workers employed in the Be industry (mainly in the 1940s) is attributable to Be. The confounding effect of tobacco smoke can only be crudely estimated. Other confounders include sulfuric acid and hydrofluoric acid; none of the existing epidemiologic studies have accounted for these confounders. Finally, Be is not the only material whose sole evidence for lung carcinogenicity in humans rests on observations of an excess of risk in short-term workers employed in the 1940s. Another prominent example is fiberglass, which has this same pattern. It is extremely problematic to base an entire theory of disease on observation of these war-time short-term transient workers. Nothing is known of their smoking experience and other industrial and non-industrial exposures. The repetitive finding of high lung cancer risk and other diseases in this group should lead to a very conservative view of acceptance of disease theories based on these people.

 

Rogers: Please include details of your quarterly surveys in your written information. Also, I was a little confused about immunological compartmentalization.

 

Deubner: The question is: Is there a theoretical basis for the observation that people may have a very clearly demonstrable immunologic sensitivity to Be in the lung, yet there’s an inability to detect that in the blood. This is still an evolving concept—the idea is that the lymphocytes and macrophages in the lung migrate there early in the development and then are self-sustaining, not interacting all that much with the similar cells in the bloodstream. There are references in standard textbooks that discuss this.

 

Sikora: You mentioned that, in one of your processes, BW lowered the total airborne mass of Be and the incidence of disease increased. Do you have any idea why?

 

Deubner: We have data that demonstrate that this area (the Be Extraction Area at Elmore, the pebble area) had exposures reduced and stabilized at much lower levels since the early 1980s. The epidemiologic evidence suggests that this area did not in fact have a higher risk prior to the early 80s but since then has had an appreciably higher risk associated with it. Why? At approximately the same time the exposures were lowered, some Be furnaces were installed next door in the same open area. It was a matter of work assignment that people would frequently work both processes. Oxide furnace work itself did not emerge as a high-risk task. But, even if total airborne levels of Be were reduced, with the introduction of the oxide furnaces, there may have been a qualitative change in the type of Be in the air. It’s our only meaningful hypothesis.

 

Sikora: Was it more due to chemical composition or particle size?

 

Deubner: That’s what we’re studying now.

 

Nadeau: Please provide cost data for your medical surveillance program; just mention the hidden costs that are difficult to get at.

Glenn Bell, Y-12 machinist since 1968: I worked with Be during several periods. I was diagnosed with CBD in 1993 after a dozen years of increasing breathing problems, which were treated as asthma. I share the views of Mr. Foster and will submit my written comments to the committee. I would like to address what may be learned from personal experience. I and several other CBD victims have had difficulty in dealing with both the disease and upper management that often minimizes our concern. Communication is the key to solving present and future differences. We as workers and management must come to understand each other better. I have a letter I wrote a year and a half ago addressed to Sec. O’Leary, answered by Dr. Paul Seligman. (SEE LETTER) "I have had little difficulty in dealing with coworkers and supervision below middle management. Industrial hygiene data workers have been cooperative in collecting years of old data from a blotched system (gaps in the records, missing samples, etc.). The first Be project at Y-12 in 1950 was conducted under extremely strict controls. No records of confirmed cases of CBD have been unearthed from this project. However, a decade later when the Be production shop was set up, controls went out the window. Full-scale production would have been impossible under the 1950 restrictions. In 1968, the area was as wide open as any nontoxic shop. Engineers, secretaries, and security personnel came and went at will; construction workers by the dozen. How many of these incidental workers may have been sensitive but were not categorized as Be workers and thus not included in the Be study? We were encouraged to take snack, coffee, and smoke breaks on the machines. Substandard local exhaust ventilation. Neither respirators nor breathing zone monitors were used. In-depth background checks of employees’ pulmonary histories were apparently not done. The Be patch test, developed in the 1950s, was not offered; it had a slight risk of sensitizing employees. Training in the potential hazards associated with Be was supposed to have been in place, but no one remembers the implementation. My attempts to locate training records prior to 1988 have been fruitless. As my asthma symptoms increased, I asked medical management about my suitability to work in Be areas. Had action been taken then, I could have had an 8-year head start on treatment. Donna Cragle has been helpful. The negativism from upper management is probably the most frustrating issue in the CBD ordeal other than the physical symptoms themselves. Questions are ignored or explained away. In my own case, no occurrence report was even generated despite persistent requests on my part. We’re finding similar happenings at other DOE sites. Apathy, personality, and fear of reprisal have kept all but a few of us from publicly expressing ourselves. Adverse national publicity is not my goal; I don’t want to see Y-12 padlocked. Too little was done in the past, and not enough is being done now. I want to again emphasize my appreciation for those who have helped."

 

I think progress has been made since that letter was written. Up-to-date information and training needs to be given that stresses how easily this disease can be contracted and how serious it can be. We seem to be doing 1990s technology with a 1940s and 1950s mindset. I have a few suggestions: (1) CBD victims should be involved in the decision making. (2) More stress should be given to sensitized individuals for continued monitoring. (3) Of prime importance, invite management, technical, and other individuals to our support group at Y-12. The bottom line is: Get away from the "us vs. them" attitudes of the past and just communicate.

 

Rogers: Asked about the type of training he received.

 

Bell: That will be included in my written presentation. Briefly, we had very little formal training when I hired in. There were procedures on the book, but I never saw them. I don’t think the main emphasis ever trickled down to the shop floor level. Training was very informal. A lot of it was strictly hands-on from veteran workers to new employees. (Tape ran out) That has changed somewhat now. A Be Training Meeting, which I attended 4 months ago, was much improved. We need more information on sensitive people--how easy it is to contract and how important follow-up is. There is a search engine that lists over 8,000 Be web sites.

Mark Kolanz: Talked about background levels of Be and detectable levels of Be. (SEE HANDOUT)

 

Sikora question: I would be interested in seeing data supporting the incidental exposures (handling paperwork, etc.) Also, are there known health hazards related to ingestion of minute quantities of Be?

 

Kolanz: For the insoluble forms, there are no ingestion hazards; it's a part of everyone’s diet. The soluble forms are only found within BW.

 

Nadeau: Asked for copies of the viewgraphs and supporting data.

Jim Phelps: My envisionment of things is not just from the Oak Ridge level but how government agencies work together. I’ll give you a little history of my experience. My dad worked at Y-12 for 29 years, and I know a lot of the behind-the-scenes issues through history and through time. I came to work at X-10 during the Reagan years on the Star Wars project.

 

These days I’m out in the private world with an environmentalist outlook, trying to figure out how to make things better for the public good, trying to fix government. So, I would ask you a question: How would you deal with specialness in enforcing this work? Historically, Oak Ridge had a Be problem with many affected workers.

 

Specialness is a term that higher-up government agencies use to reflect national security interests and how those operations tend to dismiss and not address, deviate from dealing with things properly. This applies to Be and other H&S issues here in Oak Ridge. National security worked a little bit like Carnegie ran his industries back in the old days. Carnegie was a wealthy industrialist-type person. He wanted to make a profit. He had his own spies planted throughout the industries; they headed off problems. That’s kind of how national security works. There are little formal and informal networks that report problems ahead of time, and things disappear if they look like they will cause a national security problem. Everything at Y-12 historically has been thought of as a national security problem, so you’ll see records disappearing. They’re being denied or lost from a national security point of view. We need to get past "specialness." You can find that term used by the DNFSB and all over Washington to involve these special happenings that make the system not work. In the old days, these national security boys that supplanted everything were called "the crooks" because they altered reality and affected people’s health. In some cases, they covered up people that actually died from exposures and unsafe practices at the plant.

 

A little mention of how conflicts of interest might go here: History here and power here is extreme. This was the beginning of the Manhattan Project. It involved issues like importing scientists out of Europe; many of them came here to interact with stuff. It was part of the Altos (?) project, managed by Leslie Groves, who later became the person that managed the Manhattan Project. Due to that, we’ve got a lot of Jewish scientists because they were trying to avoid Hitler’s hatred and the Jews. They came here; they came to New York City, which was the port of entry . Then, they got dispatched and monitored by the National Security boys, who kept track of them because technically they were U.S. aliens. Because of that, Oak Ridge became a place where religious issues and national security issues and good of the public and transliteration errors caused problems. These old scientists actually named the plant sites. It’s popularly told here to the public in Oak Ridge that X-10 and Y-12 are grid coordinates. They’re actually historical grid coordinates. Y-12 was named for Yahweh 12, which in Jewish is like the 12 disciples kind of issue. X-10 was named because X stood for "God" in Greek and the 10 commandments kind of issues. A lot of these old religious histories directly relate to nuclear energy, nuclear release kind of issues. There’s a huge conflict of interest between how these things are presented on the religious side as well as the U.S. policy side.

 

But, after we dropped the bomb and all that good stuff, a furor went up across the world, and the United States Atomic Energy Commission and World Court said this is a terrible weapon. So, we formed in 1946 the AEC and stuff like that, directly followed in 1947 by the CIA. The CIA’s primary study was what’s called population control theory. It’s how transliterations of religious histories go to form our religious policy. There’s a little issue with separation of church and state issues with the government at very high places. It came right out of here in Oak Ridge. So the problem is, through those methods of tilting the balance, not reporting things, the scales have tipped. We’ve got managers who don’t want people learning about cover-ups, looking for problems; the managers are all trying to dismiss problems, trying to dodge bullets. We have, right here in Oak Ridge, is the university that DOE owns, which is kind of a conflict of interest. I mean, why not places like public universities. I think we get a fair balance of things without the money interest of being employed by DOE. They have to pull the statistics toward their best possible interest. I’ve seen that done consistently here. I think the citizens get a better value for their dollar if you use the private sector because they provide a more balanced viewpoint of things.

 

Part of the problem here is that they use this way of swaying the writing. It’s called "crypto" by the National Security folks. They write things using an alternative language. In the early days, it was necessary. People that worked on enriched uranium machining, they called that work "working in the hot shop" because they weren’t allowed to say enriched uranium. There were other things that got renamed. Characteristically, the managers here, in environmental reports, have used this less visible language to the general public. So things have not been addressed in a nice, open report. In these reports, if it involves a national security issue, they rewrite it in a special language so it doesn’t appear to be a serious problem.

 

Other specialness issues: if an employee brings up a problem and pushes it, during layoffs, they are sometimes the first to be laid off. That tends to not follow Hazel O’Leary’s policy of openness. OR has a large population of whistleblowers because management didn’t like doing its job right. It still fits the Carnegie model. This is the biggest industry in this part of the country and through these behind the channels . . .

 

Roosevelt brought us into the industrial age. The industrial age meant increased toxins would be released through chemical operations. The AMA came along and doctors changed from holistic views to treatment with toxic medicines that would temporarily wipe out viruses (magic bullet point cures). They came up with antibiotics and things like that, which are stressors to the immune system. We had to put Oak Ridge here in a remote site because it was a huge toxic site. They chose a remote site where there was already malnutrition kind of impact, and they could conceal any health problem. The AMA’s approach was to deal with the toxic outlaws. Characteristically, we’ve gone on until most medicines are based on some sort of toxic effects. It works well until the population gets pre-loaded with toxic influence. After 50 years of dealing with this kind of thing, as you load a person’s immune systems, they are less able to ward off toxicity. This applies to Be. So, you’ve got different kinds of toxic effects, different kinds of mildew organisms, insecticides.

 

One of the biggest coverups is the nuclear industry here in Oak Ridge. It’s because they are strategically positioned, through this long history, to having been involved with the CIA, the American medicine issue, Roosevelt, etc. This has accumulated to such an extent that most people’s immune systems can’t afford much additional toxicity. So, what you see is a lot of people turning away from the AMA-style approach.

 

The reason Oak Ridge doesn’t like people looking into these issues is because the immune system burden is an essential part of the Star Wars project, as well as some very special weapons systems like Stealth bombers and MHD pallets (?), as well as some special alternative flight systems for Area 51.

 

So, the central problem is the immune system. (Tape ran out as he was saying something about Strontium-90)

 

As immune system loads change, the toxic level exposure to Be and other materials is also changing. You’ll get more cancers. It’s changing the medical statistics. If a person that was highly affected by a toxin was given anesthesia in a surgery thing, the more toxically burdened couldn’t afford a whole lot of anesthesia. That’s important.

 

Since you are the regulators, you need to know these conflicts of interest between the doctors and the AMA. Y-12’s got its own shrink to look at the toxic effects of people who work with highly enriched uranium because you don’t want the person that’s mad or stressed out playing around with explosives of the nuclear category because it causes messes. Y-12 has always had a shrink; the plants have medical staff. Who do they work for? They work for the DOE. One of their major incentives is to go out and help the people, but, if there is a problem, to change the wording a little bit to protect the specialness.

 

We need to do what’s good for the people. We need to do what’s good for the environment. And we need to address these failings of the system.

Howard Friedman, the Y-12 and K-25 Plant psychologist: We did recognize that we owed it to the employees who had the disease to form a support group. We have been meeting every other week for a year or two. The thrust is to share information and communicate. That really is crucial. These folks in the group deserve the information, and they are also sitting on top of a lot of information to share. Speakers for the support group have included physicians, research scientists, a social scientist from the Ramazinni Institute. Our doors are open to anyone who has tested positive on the LPT. We’d like them to come to the support group.

 

Sikora: Is your effort part of the medical surveillance program?

 

Friedman: Not really, although I’m supported by the medical department. There’s talk about forming a comparable group at K-25. Everyone in the group has gotten involved in the pulmonary rehabilitation program at Methodist Medical Center in Oak Ridge. There’s a lot of psychological stress involved in CBD, and from time to time, I’ve made referrals to psychiatrists.

 

Rogers: Asked for written comments from Friedman.
