KJ United States Environmental Protection Agency Office of Public Awareness (A-107) Washington DC 20460 JOURNA •*••'• t f V / Toxics ------- Toxics In this issue EPA Journal examines the myriad ways in which chemicals affect our lives and describes how the in- dustry has become a major force in the economy. Administrator Douglas M. Costle discusses the "chemical revolution" of the past three decades and explains EPA's current activities in regulating some aspects of the industry. Two of the major laws EPA has for dealing with toxic chemicals are the Toxic Substances Con- trol Act and the Federal In- secticide, Fungicide and Rodonticide Act. In an interview, Steven Jeilinek, EPA Assistant Ad- ministrator for Toxic Sub- stances, analyzes the Toxic Substances Act and describes how it is helping government gather information on chem- icals while safeguarding indus- try trade secrets. The magazine also has an article in which Jeilinek reviews the significance of proposed new amendments to the Fed- eral Insecticide, Fungicide and Rodenticide Act. Dr. David P. Rail, Director of the National Institute of Environmental Health Sciences, in another interview details the mission of his agency and how its research complements the work of others in dealing with health-related questions in- volving chemicals. A report by tne Conservation Foundation describes the need for more toxicologists and the career opportunities for men and women in this exciting and expanding field. Other articles deal with at- sea incineration of toxic sub- stances; the aftermath of an explosion in Seveso, Italy, and other incidents involving toxics, the effort to curb chemicals in drinking water, and plans for a major conference on urban environmental problems.

Costle, Administrator U.S. Environmental Protection Agency We've undergone in 30 years a chemical revolution in this country. In a sense, our society has become a chemical addict. The U.S. chemical industry has sales of over $112 billion a year. Practically everything we touch during a day has in turn been touched by man-made chemicals. The chemicals we use have brought us tremendous benefits, but some of them pose serious problems as well. One of our difficulties in trying to deal with hazardous chemicals, however, is that we don't know as much as we'd like to know about their impact on health. Anybody knows that carbon tetrachloride is dangerous when people are exposed to relatively large doses. But it's much less clear what happens when they're exposed to small amounts over a long period of time. PCB's are among a number of substances that we have learned are harmful— and learning that only after long years of use. DDT is an- other one, and so is asbestos, and so is vinyl chloride. The point I want to make doesn't have to do with the fact that we've now identified several dangerous pollutants. EPAJOURNAL ------- It has to do with the virtual certainty that we're going to face more grim surprises in the years ahead. EPA is now in the process of making an inventory of all the chemicals produced in commercial volume in this country, or imported for use here. When we started on this project last year we were estimating there would be 30,000 chemicals on that list. We're now betting the figure will be closer to 70,000. And we know there are another three to four million chemicals in various stages of research and development, although only a small fraction of these are likely ever to get into commerce. I'm confident that the vast majority of these chemicals will be shown to be harmless, when used properly. But with so many chemicals involved, the odds are strong that some whose effects aren't yet known will turn out to be dangerous. PCB's symbolize the complex nature of the pollution problem. Once chemicals like these are in the environment, they can be incredibly difficult to get out. Proposals have been made, for example, to dredge PCB's out of river beds, but this would involve many problems. The expense is one major obstacle. New York State thought about dredging 40 miles of Hudson River bed, but hjgs estimated that a full-scale effort could cost as much as $200 million. Even if that kind of money could be found, there would still be other tough questions to be dealt with. For one thing, something would have to be done with the huge amounts of riverbed spoil. Not many mayors would leap at the chance to bring vast quantities of contaminated spoil into their towns or cities. Assuming the disposal problem can be resolved, there's still the question of environmental damage to the river bed. For numerous waterways, this could be an especially seri- ous concern. So we're going to have to deal with the after- effects of such contamination as best we can. Our current problems with these toxic chemicals are part of a phase we're going through on the way to a totally new kind of approach. It's a catch-up phase, and like any such phase it's painful. We're dealing with problems that have developed over dec- ades. That means we've been forced to come up with after- the-fact solutions that are sometimes very complicated, sometimes very costly, and sometimes not as effective as we would like. As a Nation, we are beginning to recognize the short- comings of after-the-fact action. Congress recognized this when it passed the Toxic Substances Control Act, or TSCA, in 1976. With TSCA, we're no longer going to have to wait until the chemicals are in the water, or in the air, or in the ground, before we try to control them. For new chemicals, we're going to be able to get testing done before commerical manufacturing starts, and decide at that stage whether controls are necessary. Unfortunately, this is not going to be a quick or painless process. A great many tough decisions are going to have to be made. In the case of PCB's, some of the tough decisions have already been made. EPA has proposed that they no longer be manufactured, processed, sold or used except as part of a totally enclosed system. That means the discharge of this substance into the environment is eventually going to be cut to virtually nothing. As for many other chemicals to be regulated, we're going to have to act on many of them with less than complete, decisive scientific information. And we know that we're sometimes going to face heavy pressure to go slow. I don't intend to foot-drag if there is evidence that a chemical poses a clear threat to the health of the American people. I have always believed that public health is far too serious a concern to take chances with. I think we should be rational and reasonable, but we must also be firm and think ahead. There's no way we can calculate the cost of future harm represented by the pollution that's now in the environment. But we know it's potentially enormous. PCB's again provide an example. All manufacturing of PCB's has stopped. Nevertheless, we estimate that there are about 750 million pounds still in use; another 300 million pounds in landfills and dumps (most of it uncontrolled); and 150 million pounds simply loose in the environment. There is no doubt at all that more PCB's will be turning up in the environment, and they have a half-life of more than 100 years. We don't know yet what the effects will be in people exposed over most of their lives to some toxic chemicals. The short-term effects of some of these chemicals are well known. We know that exposure to the pesticide DBCP injures human reproductive systems, and we know that Kepone causes nerve damage. It is less clear exactly what the chronic effects of these and other chemicals are. What is clear, however, is that some do cause chronic diseases, such as cancer. I mentioned at the outset that we've launched a chemical revolution in this country. In truth we don't know yet what the sure consequences of that revolution are going to be. Reducing health and other costs related to pollution is the major benefit we realize from pollution-control programs. Other kinds of benefits—harder to "cost out"—are equally important. How much is it worth to field workers to know that the pesticides they deal with are not going to be deleterious to their health over a long period of time? To the city worker to see a clear sky? What would a child pay to be able to swim in streams that once had been too polluted to permit it? What is the value of knowing that our water is safe to drink? We cannot put a dollar-and-cents figure on these benefits. Moreover, economists don't know how to "model" the quality of life. Yet most Americans believe that such bene- fits are real, and they are demanding a clean and healthy environment. We have no alternative but to do our best to help them achieve it. D SEPTEMBER 1978 ------- Controlling Toxic Substances An interview with Steven Jellinek Assistant Administrator for Toxic Substances Can you describe how the U.S. compares with other industrialized countries in controlling toxic substances? In the case of legislation to control toxic substances, the U.S. is ahead of most of the industrialized world. A number of other countries have toxics- related legislation in place— Japan, Switzerland, Canada, and Sweden. And others are now actively considering tox- ics-related laws—the United Kingdom, France, and Ger- many, in particular. Also, the European Common Market is considering a proposal for common review of new chemi- cal substances. With respect to specifics of developing testing requirements and initiating review of new chemical sub- stances, though, we are ahead of other nations. So the short answer is that we're out front in this? Japan, Switzerland, Canada, and Sweden had toxic laws be- fore we did. But many aspects of the Toxic Substance Control Act (TSCA) and our plans for implementation go beyond those currently in place or con- templated by the other coun- tries. In general, we have much more powerful and far-reach- ing authority under TSCA. Is TSCA going to be a handicap to the U.S. in international trade? I don't think so. It certainly is the only major law that EPA administers that has the poten- tial for any significant effect on international trade. The auto- mobile emission control por- tions of the Clean Air Act also have a potential impact on international trade, but some of our foreign trading partners seem to be doing better than American manufacturers in meeting provisions of that law. With toxics, of course, we ere dealing with chemical products that as a whole involve tens of billions of dollars annually in international trade. The law re- quires us to treat importers the same as domestic manufac- turers, and that means requir- ing the same types of controls, information, testing, and so forth. All these requirements must be the same for foreign manufacturers as for domestic manufacturers. Because of this, the international community is very interested in TSCA, and that's why we will continue to meet both with representatives of individual countries and with delegations from groups of countries. They are very inter- ested in making sure that, in- ternationally speaking, efforts to control toxic substances are consistent and basically har- monious. That's why our first contacts with the international community have focused on ways to harmonize approaches to testing chemicals and to assure that tests are done adequately. Will all these require- ments be viewed as help- ing to fuel inflation and raise costs for manufacturers? There's no question that there are various ways of implement- ing TSCA that would make it more expensive for chemical companies to do business than if the Act did not exist. But the chemical industry represents an extremely healthy and profit- able sector of the American economy, and I believe that any of the costs we wouid conceiv- ably impose under TSCA would be absolutely minuscule com- pared to the industry's sales, assets, and profits. Further- more, I don't think we're talking about any kind of major eco- nomic impact from TSCA im- plementation. And the benefits that we jvould realize from these economic impacts—ben- efits to the Nation's public health and environment stem- ming from the wise control of toxic substances—would far exceed any adverse economic effects. EPAJOURNAL ------- You pointed out in a re- cent speech that there are 14 other major Fed- eral laws concerning some aspect of toxic sub- stances, in addition to TSCA. How does TSCA make a major contribu- tion to solving our prob- lems? TSCA provides EPA with sev- eral unusual authorities that don't exist under any other Federal toxics-related law. The other statutes generally are of two types: those that concern wastes or by-products of manu- facturing, such as the toxics- related provisions of the Air Act, the Water Act, the Ocean Dumping Act, and so forth, and those that deal with special categories of toxic chemicals and involve licensing or regis- tering those products, such as pesticide or drug registration laws. There's also the Occupa- tional Safety and Health Act, which in part focuses specifi- cally on worker exposure prob- lems. However, TSCA is very broad and very comprehensive. It deals with chemicals and products, per se, throughout the life cycle of the chemicals —through manufacturing, dis- tribution, use, and disposal. So it encompasses the entire spec- trum of interest that one might have in toxic chemicals. It also provides EPA and the Federal Government with some very important new authorities. In enacting TSCA, Congress recognized that there must be a way for the Government to gather various kinds of vital information on chemicals. One of the things that we knew most about chemicals was that we didn't know enough. For exam- ple, we didn't know which chemicals were being manu- factured, what volumes were being manufactured, and what health and environmental ef- fects they caused. We kept getting hit with "chemical-of- the-week" or "chemical-of-the- month" scares, and we were unable to anticipate these prob- lems. TSCA has two important provisions to help solve this problem. One gives us the authority to gather basic chem- ical-related information so we can make more informed deci- sions. Section 8 is the informa- tion-reporting and record-keep- ing part of TSCA that gives EPA the authority to collect all kinds of information from industry on chemical production, use, ex- posure, by-products, impurities, and so forth. The section 4 testing provisions of the Act give EPA the authority to re- quire that industry actually perform tests on chemicals in order to develop health and environmental effects informa- tion that may not have existed at all or, if it did, was not avail- able to the Federal Govern- ment. With that kind of infor- mation, not only will EPA be better informed about chemical risks, and therefore better able to control what appears to be the most unreasonable risks, but other agencies such as the Occupational Safety and Health Administration will be better informed about the kinds of chemicals that workers deal with. Right now OSHA doesn't have the authority to require testing or require certain kinds of information from manufac- turers. Often, OSHA doesn't know what actually is being produced by a given chemical company. We'll be able to help OSHA do its job better by col- lecting information that they can use. The information that we get on health and environ- mental effects through the use of TSCA will be useful to the EPA air and water programs, too. If a problem is so pervasive that it cannot be controlled effectively through any other Act, then the law says that TSCA ought to be brought in to do the controlling. That is one of the new and different things about TSCA. Another unusual feature of TSCA gives EPA the authority, under section 5, to review notices from manufacturers of their intent to put new chemi- cals on the market. Based on the results of this review, we can take action to stop or limit the introduction of new chemicals if we think they will cause un- reasonable risks to health or the environment. Beginning early next year, every new chemical will be subjected to this premanufacture notifica- tion requirement. EPA will have 90 days, extendable to 1 80 days, to read the notice and decide whether to take action. If we decide not to take action, the chemical goes on the market. TSCA's premanufacture re- view authority is different from the pesticides law in that it's broadly applicable to all new chemicals. Pesticides are regis- tered for very specific uses as chemical products that are in- tended to be poisons and there- fore require special attention. With TSCA, every new chemi- cal is considered a potential problem, and the premanufac- turing notification process gives EPA a chance to identify and stop those that have the greatest potential to create problems. Does the Act authorize you to select priorities for which toxics you're going after, and why? There are all kinds of priorities. Institutionally, we feel that we have to give priority in these first few years to establishing the Act's basic testing, infor- mation-gathering, and preman- ufacturing notification func- tions so that we can provide the basis for a long-term, effec- tive control program. It takes a long time to build a case against chemicals. You must have information available, you have to know how to use that information, and how to de- velop it into a risk assessment that identifies what the prob- lems are and demonstrates that the problems are greater than the benefits. So we have a long pipeline to fill, and we recog- nize that we have to start filling it with adequate risk assess- ments and information right from the beginning. By law, of course, we have a statutory deadline to get the premanu- facturing notication program going, and we are giving prior- ity to that. In addition, we are identify- ing high-priority chemicals for early regulatory action. The Act encourages us to give high pri- ority to those chemicals that cause cancer, birth defects, or gene mutations. We're trying to identify those chemicals, based on existing information, that are highly toxic, whose health effects are indisputable, and that are widely used and, there- fore, widely exposed to people and the environment. We are placing highest priority for early regulatory action on chemicals that have high ex- posure, are highly toxic, and for which the case is relatively well made. We don't want to wait two to three years before regulating our first chemical. Right now, we're looking at substances like asbestos, ben- zene, and some of the other known human carcinogens and highly toxic chemicals. What about radioactive wastes? Is that out of TSCA's jurisdiction altogether? TSCA excludes certain sub- stances that fall within the scope of other laws. Radio- active materials that are regu- lated by the Nuclear Regulatory Commission are excluded for purposes of this Act, for exam- ple, as are drugs and food addi- tives, which already are regu- lated by the Food and Drug Administration. Congress didn't want us to duplicate other reg- ulatory programs, so they spe- cifically prevented us from dealing with them under TSCA. Are all toxics "poisonous?" I can't give you a simple answer to that. By definition, all pesti- cides are poisonous to some- thing. Their purpose is to kill insects, weeds, microorgan- isms, and so forth. Not all chemicals are poisonous, but any chemical in any amount may be a poison, in the sense that it may have a deleterious effect on the organism it's inter- acting with. There's no defini- tion of a "toxic substance" in the Act. SEPTEMBER 1978 ------- I assume in your work you are going to find that some toxic substances are in fact poisonous and require appropriate deliberation to protect human health and the environment. Yes, of course. We're going to look at individual chemical substances and then decide under what conditions the chemical is exposed to people and the environment. Then we'll try to determine whether those conditions are dangerous or pose unreasonable risk; if so, they will have to be controlled. How do toxic substances differ from pesticides? TSCA excludes pesticides, which EPA regulates under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). With pesticides, we have a reg- istration program in the truest sense. You cannot legally put a pesticide on the market without getting EPA approval, or regis- tration, and you cannot change the use of a pesticide without EPA approval. There arc a num- ber of other things you cannot do with pesticides without get- ting EPA approval. TSCA, on the other hand, is wide open. By that I mean it requires EPA to use its own discretion to identify and control problems as they become known. FIFRA puts the burden on the manu- facturer, who has to say: "Here, I want to use this pesticide. Approve or disapprove it." TSCA is much more flexible and puts a completely different type of burden on industry and EPA. Other than that, there are a tremendous number of sim- ilarities between TSCA and FIFRA when it comes to inves- tigating the health and environ- mental risks of chemical sub- stances. But under TSCA, we're looking for other chemical prod- ucts in the industrial process, in consumer products, and in intermediate chemical busi- nesses; we've got to find toxic chemicals, to identify them, and to make sure we're working on the most important ones. How many chemicals must EPA deal with under the TSCA? Our rough estimate is that 70,000 chemical substances are in commerce in the United States. About 111,000 chem- icals have been reported to us on forms by the entire chemical industry as part of the initial chemical inventory under TSCA. Many of those compa- nies, of course, produce the same chemicals, so there is a lot of duplication in that figure. We are processing those forms and will shake out the dupli- cates, so the final number will be much lower than 111,000. It may even be lower than 70,000. Could you give us a thumbnail description of how the Act will enable you to handle this enormous number of chemicals? Chances are very good that most of the estimated 70,000 chemical substances are not toxic, at least in the ways they are normally used and exposed to people and the environment. Probably 80 or 90 percent of them are not toxic in the sense that they don't present unrea- sonable risks to human health and the environment. Also, we expect that most of the 70,000 are manufactured in small quan- tities. And we think that rela- tively few of them—maybe 10 to 20 percent—are manufac tured in significant quantities, meaning over 100 tons or so. We will know more about this when the chemical inventory is completed later this year, be- cause we've asked for produc- tion information. We have to identify the high- volume, high-toxicity chemicals and focus our efforts on those that appear to pose the biggest problems to the most people. !f we had all the staff in the world, theoretically we could investigate every one of those 70,000 substances even if only five tons of a chemical were manufactured once every other year for some special, com- pletely enclosed use in a reac- tion vessel in some small fac- tory in Peoria. But realistically, we can't waste our time on that. The job, as Congress recog- nized, is to find out which chem- ical substances are the impor- tant ones, and to determine how they affect human health and the environment. I assume you'll use com- puters extensively in the inventory work? Yes, we will. The inventory it- self is being put in a computer system so we can easily retrieve the information as it's needed. Much of what industry has re- ported for the inventory is con- fidential, meaning that it in- volves trade-secret information. Consequently, we are setting up two separate computer systems. One will only handle confiden- tial business information, and keep it physically separate from the other system so we can maintain the requested con- fidentiality. Then there will be a public file of all the information that is not confidential, and it will be available to anyone who needs to use it. That file will include aggregations of some of the confidential data that can- not be identified by any individ- ual company, but we fully ex- pect that enough information will be available for analysis to understand the nature of the chemical industry and the prob- lems TSCA was enacted to control. What safeguards are being taken to protect the trade secrets? Over the past several months, an internal EPA task force has developed a very thorough set of security procedures to ensure that this information is handled carefully, and that it is not dis- closed inadvertently. In the unlikelihood that some trade secret is willfully disclosed in an unauthorized manner, the Act itself provides some fairly stiff criminal penalties, which EPA employees and others au- thorized to use the information are subject to. Can you describe how a fully implemented TSCA might have prevented such past toxics-related disasters as those invol- ving DBCP, PBB's and Kepone? The Act gives EPA the power to identify problems before they develop, particularly with new chemicals. We will have certain information on a chemical in front of us before it goes on the market. We'll be able to decide at that point whether it's going .to be a problem. So if we saw a sterility problem in animal tests—as in the case of DBCP, for example—we could have flagged that for more attention and have gotten ahead of the problem before many people and the environment were exposed to the chemical. I should mention, however, that our ability to identify prob- lems beforehand will only be as good and as thorough as the competence of our staff. Thus far, the Agency, the Adminis- tration, and Congress have been very sympathetic toward our staffing needs, and we expect to be increasing our staff in the months and years ahead. I've been encouraged with the excel- lent quality of people we've been able to attract to the pro- gram so far. And in addition to EPA's own efforts under TSCA, of course, industry knows that we will be looking over its shoulder. Not only that, but we're going to be between in- dustry and the market place. I think these factors will have their own impact on the way industry makes decisions on chemicals. Industry will try to identify and avoid potential problems ahead of time. So TSCA will have some indirect influence that we hope will help prevent many kinds of problems that have occurred in the past. My understanding of the PBB catastrophe in Michigan is that it largely involved a tragic hu- man error. A highly dangerous chemical was accidentally mixed with cattle feed. As ter- rible as this was, I doubt whether EPA or TSCA could have done much at the time, or Continued on page 23 EPA JOURNAL ------- The Team Leaders Four Deputy Assistant Admin- istrators help Steven Jellinek run EPA's program to regulate toxic substances and pesticides.

SEPTEMBER 1978 ------- By John Heritage American Back in 1971, a little girl named Andrea Piatt became mysteriously ill in her Missouri home. She was hospitalized im- mediately, suffering bladder pain, diarrhea, bloody urine and headaches. tt took more than three years for scien- tists to find the culprit. Andrea had unknow- ingly been exposed to a highly toxic chemi- cal, TCDD, adioxin. The poison was a by- product in the making of hexachlorophene, an antiseptic. The TCDD that sickened Andrea was so potent that it killed hundreds of birds, dozens of pet dogs and cats, many rodents and even the flies where the chemical had been sprayed. Mo re than 60 horses also died. Andrea's tragedy is an example of why the Toxic Substances Control Act was en- acted. With this new legislation, which went into effect in 1977, Congress acted to head off similar incidents in the future. Here is the rest of Andrea's story and some other disasters that the new law was designed to prevent. TCDD Andrea liked to play in the big barn and horse arena on a farm near Moscow Mills, Mo. Then on May 21, 1971, a truck drove up and sprayed the earthen arena floor with about 2,000 gallons of what Andrea's mother and her business partner were told was salvaged motor oil, to keep dust from blowing around. Three days later, the birds began to die. By the time Andrea was hospitalized and hundreds of animals were dead, everyone involved suspected that something in the waste oil had caused the epidemic. But no one knew what. The answer even eluded scientists at the Center for Disease Control in Atlanta. Finally, a lexicologist who had read about TCDD in Germany proposed that soil from the horse arena be tested for it. The test confirmed the poison's presence. The TCDD was traced to a tank of waste liquids at a chemical plant 350 miles from the farm. The plant was making hexoachloro- phene, and TCOD was one of the leftovers.

The plant owners had contracted with a chemical distributor to get rid of the wastes. Under subcontract, a truckload of the contaminated liquids had been hauled to a storage yard in St. Louis, and the truck later sprayed the TCDD-tainted wastes on the horse arena where Andrea played. The TCDD trail showed the conse- quences of ignorance and lack of effective regulation. When an industrial waste with dangerous TCDD got into circulation, death and illness were the result. Tris Children also were involved in another more recent episode. Back in 1972 the U.S. Department of Commerce set mandatory flameproofing standards for children's nightgowns and pajamas. A fire retardant chemical called Tris appeared to be an economical and convenient answer to the rules. Soon it was being applied to about half the children's sleepwear sold in the country. At the time it seemed that one hazard of childhood had been lessened, because in 1973-74, the first year flame-proofing was mandatory, children's burns and deaths from clothing fires showed a decline. But then another problem surfaced. EPA-funded research at Columbia Umver- EPAJOURNAL ------- sity showed that Tris had the potential to cause mutations or changes in cells. In late 1975, EPA reported the results. By Feb- ruary, 1977, National Cancer Institute data showed that Tris was a highly potent cancer-causing agent in test animals. Other research showed the chemical could be absorbed through the skin. In April, 1977, the Consumer Product Safety Commission halted the production and sale of Tris-treated clothing. Based on available data, it was estimated that 300 out of every million male children wearing Tris-treated pajamas for 12 years would develop cancer. The dream of an easy answer had dis- appeared. In the effort to protect children from fire, millions had been exposed to a cancer risk. The threat hadn't been checked before the first safety rules were issued. By the time health action came, Tris-treated nightwear had been used from coast to coast. It was yet another demonstration that the public needed the protection of the new toxics law designed to help detect carcinogens before they found their way into the marketplace. DBCP Workers were the victims in still another toxics incident. This time, the workers be- latedly learned something was wrong, but damage already had been done. The story broke on network television in late July, 1977. More than a dozen workers at the Occidental Chemical Company in Lathrop, California, had become sterile or had very low sperm counts. A soil fumigant known as DBCP was believed to be the cause. The chemical was widely used to protect crops from root-destroying round- worms. In less than two weeks, production of DBCP in the U.S. was halted voluntarily and California banned its production, sale, or use. Moving with unusual speed, the Federal Occupational Safety and Health Adminis- tration completed the complex steps to set an emergency standard on DBCP to sharply restrict the levels of the chemical to which plant workers could be exposed. EPA suspended and announced its in- tent to cancel DBCP use on 19 crops with edible roots, and set special handling rules for other DBCP uses. The Food and Drug Administration said it would monitor farm produce headed for market to check the chemical's residues. Although Government, industry and la- bor had moved quickly once the national publicity focused on the problem, warning signals actually had been flashing for 1 6 years. Ina 1961 study commissioned by industry, DBCP was identified as damaging to laboratory animals. At the lowest level of exposure studied, breathing DBCP vapors was found to harm the liver, kidneys and various tissues including sperm cells. The report was published in a professional journal. As early as 1973, National Cancer In- stitute studies had identified DBCP as a cause of cancer in animals. In March, 1976, an employee at the Lathrop plant, Ted Bricker, was told by a doctor that he had an abnormal sperm count. The diagnosis contributed to worker and union concern about possible hazards at the plant. The long lag in controlling DBCP had many reasons. Facts were known but not forcefully communicated. Industry's rec- ordkeeping had been spotty. The occupa- tional health establishment seemed to be preoccupied with other ailments. And of course TSCA, with its new requirements to fill in the gaps left in other toxics laws, was not yet in existence. PCB's A toxic substance can do far more than harm workers in a chemical plant, or con- taminate children's pajamas. It can taint the whole environment—the rivers, the land, the sea, wildlife, humans. The case of PCB's shows how this could occur. Spring is usually a time of increased activity along the Hudson River in New York. The fishermen turn out to tap the river's wealth. Samples of dirt taken from tho bank of the Sheboygan River showed the site to be a source of PCB contamination to the watershed. At one time hydraulic fluids containing 12 percent PCB's were deposited here and the chemical has since been leaching from the soil. But since February, 1976, the Hudson has been different. Both sport and commer- cial fishing have been banned on much of the river by the Commissioner of the State Department of Environmental Conserva- tion. The river has become contaminated by a class of toxic chemicals called polychlori- nated biphenyls, or PCB's. Worse, despite corrective action by the main polluter, General Electric Co., the Hudson probably will be tainted for years. One eel was found to have 559 parts per million of the chemical. The level was so high that an adult who ate a 7-ounce por- tion would get 50 percent of his iifetime "allowance" of PCB's in a single serving. Said one long-time Hudson River fisher- man, "Shopping in a fish market these days is like picking your way through a mine- field." The concern about PCB's was under- standable. In 1968 in Japan, a machine leak of the chemical into rice oil caused a tragic poisoning. The 1,500 victims of yusho, or oil disease, suffered skin lesions. swollen limbs, and eye and liver problems. The accident called wide attention to the danger from PCB's. Over a period of 30 years some 230 tons of PCB's had built up in Hudson River sedi- ments, mostly from two GE plants that had discharged PCB's with waste water. It would cost as much as $200 million to dredge the contaminated bottom, accord- ing to one estimate. The worst of the buildup was in a 40- mile stretch of the river, but the chemical was reaching far from the Hudson. By 1972, the PCB's had been found in every major river system in the U.S. Prized coho salmon in Lake Michigan were tainted. The substance was found in some of Ohio's milk supply. PCB's were accidentally sprayed on 800,000 pounds of tuna meal in a Puerto Rican warehouse fire when two electric transformers burst. Like its distant relative, DDT, the chem- ical was everywhere. It was estimated that 51 percent of the people in the U.S. had some PCB's in their bodies. Meanwhile, research was implicating the compound in cancer and birth defects. Among other results, high PCB doses killed laboratory test animals. Because the PCB's are chemically stable, fire resistant, and don't conduct electricity, they had been widely used in electrical equipment for many years. Other PCB-aided products included adhesives, paints, insulating tape, printing inks and plastic. Some 450 million pounds of the PCB's had built up in nature and in often- leaky landfills and dumps, according to estimates. EPA has proposed an end to the manu- facture, processing, sale or use of PCB's except as part of a totally enclosed system.

But the compound remains in lakes, rivers, dumps, fish and people. It is a memorial to nearly half a century of ignorance about the hazards of one industrial compound. What were the reasons for these various toxics episodes? How could the United States, with a long history of public pro- tection, allow them to happen? The trouble reaches back to the years after World War II, when an explosive growth in U.S. chemicals began. The trend promised to boost the Nation's living standards, though with a little-noticed drawback. By the 1 970's, the chemical revolution had transformed America, in everything from soap to skyscrapers. As many as 70,000 chemical substances were in the marketplace. Sales in the industry were more than $112billionin1977. But in the birth of the chemical age, a big question was overlooked. !t was the possible danger to the public's health, especially from chronic disease. Only a few thousand compounds had been ade- quately tested for chronic health and en- vironmental effects. Little was known about the long-term risks of existing chemicals being marketed, let alone new ones not yet in commercial production. Unwittingly, the Nation itself had be- come a laboratory. People were being tested, not the chemicals. The doses could be heavy from products, wastes, and accidents. Few Americans had any idea until re- cently that they were living so dangerously. They didn't know that when they did or- dinary things such as eating, drinking and breathing, they could be laying their lives on the line, playing a game of chemical roulette. It took endangered children, contami- nated fish, dying horses and other incidents to alert the public to the long-term risks some chemicals pose. The new toxics law gives EPA strong authorities. Tests may be required on po- tentially harmful chemicals. Manufacturers must notify EPA of planned production of new compounds for the marketplace. The EPA Administrator can take action de- signed to keep a new chemical off the market. The Administrator has the author- ity to control existing substances as well. The philosophy of preventive action is now functioning to protect the public from exposure to toxic substances. Although the law is no guarantee against human care- lessness or willful neglect of safety meas- ures, it does set up many new precautions and imposes major penalties against viola- tors. While it is too early to gauge its effects precisely, observers agree that the Toxic Substances Control Act has given Federal officials a weapon that promises to greatly reduce the likelihood that com- pounds like TCDD, Tris and DBCP can reach the consumer in the future. D 10 EPAJOURNAL ------- Environmental Calamity • By Marion Parks ore than two years ago in Seveso. Italy, an explosion in a small factory producing trichlorophenol for export to the United States brought in its aftermath all the kinds of costs and consequences that environmentalists have antici pated and sought to forestall through timely and appropriate regulation. The Seveso case has shown through a tragic disaster why we need to protect the health of people and the en vironment from accident or misuse in the management of toxic substances, under the conditions of massive chemical production of our times It shows as well the enormous costs to the public and the burdens and losses for the " dustry that can ensue when such protective regulations f-ui Marion Parks is vice president of the Rachel Carson Trust for the Living Environment, Inc ------- or are lacking. The story is still far from ended and the toll of its costs on society will continue for a long time into the future The explosion on July 10, 1 976. at the ICMESA chemical plant in Seveso, some 1 2 miles north of Milan, showered a populated area of more than six square miles with a fallout of trichlorophenol, ethanol, caustic soda, and tetrachloro- dibenzo-para-dioxin (TCDD), a substance characterized by the President's Science Advisory Committee Panel on Herbicides as "extraordinarily toxic." No other agent, indeed, has yet been discovered to be more toxic. In research as small a dose as 0.0006 milligrams of TCDD per kilogram of body weight killed one-half of the female guinea pigs to which it was fed. Its effects vary with different antmal species that have been tested, but only slightly. 11 has been established that TCDD is teratogenic; i.e. it causes birth defects in develop- ing animals and may be lethal to the fetus or cause abortion. It tends to cling or bond with particles of dust, silt, or organic matter and may be ingested or inhaled It has poisoned humans and large animals such as horses through skin contact. Extensive records of sickness due to con- tact with TCDD show that its most conspicuous symptoms a re chloracne, a severe skin disease that is very resistant to treat- ment, and in some cases hirsutism, an unnatural and dis- figuring growth of hair over the forehead and sides of the face, as well as serious liver and kidney ailments. Many other symptoms occur, including persisting debility and psycho- neurotic reactions. Whether TCDD is cumulative in living tissues has not been determined but is under investigation in several research studies. Some research in Germany and France has indicated that it may be carcinogenic, i.e., a cause of cancer. This has not been confirmed. There is no antidote that can reverse or modify the effects of TCDD. The tetra-dioxin mole- cule itself is nearly indestruc- tible. Its biodegradation in soil takes place very slowly To some extent the process may be stimulated or aided by sun- light; when the TCDD becomes embedded deeply into soil cracks and crevices, this action has little effect. TCDD is in- soluble in water but can be transported mechanically by water and lodges and persists in silt. It can be removed from various surfaces with solvent or diesel oil, but is not quanti- tatively diminished or altered in its action. Therefore it remains unchanged in the washing agent and containers, which are then permanently contaminated and can induce chloracne in handlers. Tetra-dioxin can be disinte- grated and consumed by heat, but only at sustained tempera- tures above 2500°F, much above the capacity of any ordinary incinerator. Application of heat at lower temperatures seems to intensify its reaction. According to some analysts it may have the potential of multiplying its own quantity under certain conditions of heating. It is possible to synthesize TCDD in pure form for research purposes, but no refinement of the manufacturing process has succeeded in eliminating its occurrence as a contaminant in trichlorophenol and related compounds. These include phenoxy-acetic acid herbicides such as 2,4,5-T; hexachloro- phene, a bacteriocide used in deodorants and germicidal soaps; and pentachlorophenol, used as a wood preservative. In most current production of these compounds, TCDD con- tamination is kept at levels below 0.1 part per million. The products are used in agri- culture, forestry, cosmetics, and in hospitals (surgical soaps, for example), on the theory that at a very low level the presence of TCDD does not constitute a threat to human health, al- though there is disagreement among scientists regarding this theory and its interpretation. The trichlorophenol products are synthesized from the basic material ethylene, a re- finery by-product. The manu- facturing process requires several steps in several types of chemical plants, which may be located in a single complex or widely separated from each other. The ICMESA chemical plant of Seveso is owned by the Givaudan corporation, a sub- sidiary of the giant Hoffman La Roche pharmaceutical company based in Switzerland. ICMESA's production, according to com- pany spokesmen, was limited to trichlorophenol, all of which was shipped to the Givaudan plant in Clifton, New Jersey, for conversion into hexachloro- phene. The ICMESA instalfation is relatively old, a small establish- ment, employing about 1 57 workers, a Swiss manager and engineer, and an Italian chemical engineer. It is situated in an en- clave of former farmland which is in the process of suburban conversion. The area around it is not an industrial zone but typically suburban, with large, substantial business centers in the towns or communes of Seveso, Cesano Maderno, Meda, and Desio, which all blend into each other. In a mixed pattern on the fringes of each one there are houses with garden plots large enough to grow a few fruit trees and vegetables and to keep chickens, rabbits, and a type of small Asian goat which has been popular in the area; two- to four-story apartment buildings; and scattered throughout the four communes a multitude of small and medium artisan shops, with some 25,000 em- ployees. The shops produce fur- niture, mostly for export to Switzerland and other European countries. The heavily traveled modern freeway running northward from Milan to the Swiss frontier skirts the east side of the ICMESA plant. The housing development, which was hardest hit by the chemical fallout, is situated between the freeway and the factory. About a mile- and-a-half to the west of ICMESA is the Seveso City Hall, a large dark stone and brick building. Between it and the factory lies a street of rather large homes with tree-filled grounds, and opposite them the stretch of land and large build- ings owned by the Seminary of St. Augustine, and between there and the factory a few blocks of mingled shops and dwellings. The local health and labor authorities did not know what was produced at ICMESA. They did not know where the product was shipped or in what quantities, whether toxic wastes were generated, or what disposal was made of them. No information on that score is available now. A few years before the accident, the Seminary sued the company because some of their cows I.' EPA JOURNAL ------- ZMA INQUINATA DWEIO nssoiuro 01 ACCESSO Barbed wire fences cordon off some of the most badly contaminated areas of the town. were poisoned by water from the Seveso river, which runs near ICMESA, but did not ob- tain a judgment. The factory Workers' Council had requested information through the local authorities about the chemicals they handled in order to deter- mine occupational hazard two years before the explosion, but a reply from the company was still pending. Italy has no government agency for environmental over- sight. Its laws regulating indus- trial pollution are old and bear little pertinent relation to con- ditions of modern petrochemical operations. The almost unlimited expansionofthisindustry, under few restrictions and lax inspec- tion policies, has been en- couraged in order to gain its input into the weak national economy. As an outcome of the Seveso disaster a govern- ment census of industry throughout the country has been urged and demands for regulation under new laws and more enforcement of such regulations as exist, have been voiced in Parliament. On Saturday, July 10, 1976, at noontime, the runaway ex- plosion took place in the ICMESA reactor, as a crew of six or eight workers were shutting down the plant for the week-end. In a split second the chemicals in the 2,000-litre tank roared up with a force that the control valve failed to con- tain, and shot out through the vent opening to the outside of the building in a rolling greyish- white cloud. It later was esti- mated to contain some 500 kilo- grams of sodium hydroxide methanol and tetrachloro- benzine, the basic components of trichlorophenol. By official estimate two to three kilograms of TCDD were suspended in this mass. Some observers believe it may have been much more. At the lowest estimate, considering the extraordinary toxicity and persistence of the tetra-dioxin, it was a staggering amount. The manager of ICMESA said that 1,000 kilos of trichlorophenol and perhaps some TCDD re- mained in the reactor Volun- teers were trying to clean it out. One worker developed severe chloracne. Similar, indeed practically identical, accidents have happened in the production of trichlorophenol over a stretch of years since 1 948, twice in chemical plants in the United States, twice in Germany, once in England, once in Holland. In each instance workers and others in contact either with them or something in the plant have suffered chloracne and other sickness requiring medical care for prolonged periods. Contamination of the buildings and equipment with the tetra- dioxin was ineradicable to a degree requiring demolition (under extreme precautions) and the rubble was put under cement and buried or dumped at sea. In every instance, prior to the explosion at Seveso, the poison was contained within the factory. The injury and sickness of workers, their treatment and compensation. dismantling of equipment, demolition of buildings, and disposal of the rubble all were internal matters for owners, managers, and company physicians. The reports of the latter, published in some scientific journals in England and Germany, were of prime importance to the Italian health officers in identifying, con- firming, and coping with the Seveso disaster. In Seveso for the first time, such an accident became a public affair, a regional disaster. No health officials were pre- pared for it. The body of refer- ence information they needed was extensive but not codified, readily accessible or definitive. The more they learned from it. the more appalled they became. Responsible officials nonetheless had to take the terrible risks of decision in that nightmare situation with no firm prece- dents to guide them and under enormous pressures to find a quick fix and avoid public panic On July 30, twenty days after the explosion, the Minister of Health, in defending the government for not having acted faster than it had, said that "no similar accident has occurred before in the world," adding that it was not possible yet to decide the best way to decontaminate. That decision, in fact, has not been fully settled on up to this time. SEPTEMBER 1978 13 ------- A momentary wailing whistle accompanied the es- cape of the chemical cloud out of ICMESA and a stench filled the air. The day was fair with almost no wind. The vaporous mass settled to the ground, bounced upward, descended again, and vanished. Its load of sticky vapor and fine white crystals settled visibly on vege- tation and walls and drifted invisibly far beyond the ap- parent area of its fall ICMESA offered the first map of the area contaminated. It ran in the shape of a triangle with the apex at ICMESA, south and eastward from the factory. The first estimate was 1 2 hectares or 268 acres Day by day, for many weeks afterward, the zone of impact was to be extended by new discoveries of the pres- ence of TCDD. As of now, a plot of some 1 50 acres has been sealed off from any access, and is deemed unusable for at least 1 0 years, perhaps longer. People for the most part were indoors at their noonday meals when the explosion occurred, but a few little child- ren were playing outside. Some of them ran to the cloud, laughing, with arms out- stretched. It looked to them like snowflakes. Those children are still sick, disfigured with stub- born chloracne over faces and arms, destined to years more of treatment and eventual plastic surgery. Many adults became nauseated and had headaches after the cloud came down. But they were accustomed to the occasional noisome emissions from ICMESA They ignored this latest one and waited for the effects to pass 01 Sunday afternoon, two •epresentatives of the man- agement of ICMESA sought out the health officer and the Mayors of Seveso and Meda. They said the people should be warned not to eat fruit, vege- tables, poultry, or rabbits from their yards. Samples of soil and vegetation from around ICMESA were collected and sent to the company laboratory in Dubendorf, Switzerland, for analysis Flowers and leaves touched by the fallout were beginning to wilt. There was evident damage to crops in the path of the cloud. On Mon- day and Tuesday some adults reported illness and children were suffering with body rash. Domestic animals were sicken- ing. On Tuesday they began to die. The veterinarians found hundreds of wild birds, seem- ingiy including a whole flock of swallows, dead on the ground. Wherever they went, they encountered dead field mice and moles. Friday, July 1 6, the workers closed down ICMESA. At 6:30 that evening the management told the health authorities that the emission "was toxic." The acting health officer stated that the people should be evacuated from the contaminated zone. Twelve children were hospital- ized. The Mayor ordered the preventive destruction of the vegetation and the animals in the zone, the carcasses to be doctors noted that the lesions were of a type not encountered before. On Tuesday, July 20, ten days after the explosion, it was confirmed both for the health authorities and the pub- lic, that the poison they were dealing with was TCDD. The following day 444 people were evacuated from their homes and housed in a large hotel complex about ten kilo- meters away, near Milan. Eighty children were sent to summer camp at Lake Como. Physicians and scientists began to mobilize. Health and public authorities held meetings daily. From some quarters a demand was raised to burn everything to the ground. A military contingent arrived with armored trucks and flame- throwers and remained on call for weeks, to the intense alarm Worker clad in protective garb is cleaning dioxin residues from a homo insido thn affected area in Seveso. picked up by truck squads from ICMESA and held there. At five o'clock the next morning, ICMESA sent trucks with spray equipment around to douse the vegetation with lime. The workers refused to go back to the factory. The Mayor ordered it closed and on July 1 8 a judge ordered its sequestration. The only other factory in the immedi- ate area, a plant which made children's clothes and employed about 80 women workers, was ordered closed. Fourteen children were now hospitalized with rash and skin lesions. The of some of the scientists and health officers. Burning was held in abeyance while other possibilities were studied. It was proposed to remove a layer of soil to the depth necessary to remove the tetra-dioxin pene- tration and spray the earth taken away with a layer of plastic. Two American military of- ficers, believed attached to NATO, appeared, took soil samples, and went away mys- teriously. The memory of U.S. military use of herbicides in Vietnam intruded frequently, and was like a stage ghost every little while stalking through the scene. Insistent demands were made on the public authorities to summon the Vietnamese doctor Thon That Thun as a consultant. His advice, electronically trans- mitted to the press, was to watch for the protection of the natural defenses of the body organism in exposed people, apply antibiotics, immuno- stimulants, and prescribe Vita- min C. His advice regarding de- contamination was picturesque if not practical: wash everything down with white Marseilles soap. This was no stranger than another scientist's proposal to put olive oil on everything. There was logic in both suggestions, as TCDD, like other organochlorine chemical formulations, is lipo- philic, or fat-attracted. The problem always re- mained, with any proposal, of disposing finally of the TCDD however it might be removed from the soil, house walls and roofs, school interiors, wherever it was encountered. It was soon shown that the seriously con- taminated zone was much larger than first estimated, and beyond it a still greater area was de- signated as a "zone of caution". The final estimate of the amount of soil into which TCDD had penetrated and lodged, by depth and area, was 99,000 metric tons. Removal in the foreseeable future was an im- possibility. Burning was perhaps the worst of all proposals, since some of the TCDD, re- leased from where it lodged but not destroyed, could be distributed more widely than ever in smoke and ash and carried into the soil somewhere else by rain. A serious study was made of constructing, probably close to the ICMESA site, a special in- cinerator capable of consuming TCDD by subjecting it to the necessary high temperature. Public fear and resistance to this idea led to citizen protest demonstrations. For the present, the scheme remains in abeyance. Some people, how- ever, looking at what has be- come not only a national prob- lem of Italy but a world problem — the safe disposal of chemical wastes—have thought of put- l.l EPAJOURNAL ------- ting up such an incinerator on a part of the wasted and ruined ground of Seveso as a point of disposal for toxic chemical wastes from all Italy and pos- sibly a larger area. On July 23, ten days after the explosion, a heavy rain fell on the Seveso region. Many fears were expressed that the run- off would carry the poison into the underground water basin (most of the area is supplied by wells) and the river system emptying into the Po. These fears have neither been borne out in experience nor entirely allayed. The soil of the contaminated area is largely clay; it tends to crack when dry but is not very porous. It is thought that most of the tetra-dioxin was washed into these crevices and for the most part remains there. This would account for much of the high concentrations and persistence of the poison and the ultimate decision to seal off such a large part of it against any occupancy or use—for ten years or longer as may turn out. The Givaudan company spokesmen in Switzerland told the press shortly after the ex- plosion that the company was financially able to pay the costs of rehabilitating the con- taminated area and would take charge and do so, but this pro- posal was rejected by the gov- ernment of Lombardy Prov- ince and the local authorities. Givaudan hired the British chemical engineering firm of Cremer and Warner as con- sultants and they conducted tests on the ground in Seveso. In the last week of July, 1976, and early August, the formu- lation of lawsuits against ICMESA and Givaudan was be- gun by the Lombardy Regional government, the labor union, and other entities. The technical director of ICMESA was placed under arrest charged with "culpability of causing a disas- ter and harmful disregard of the misfortunes caused by his ac- tions." His release was later obtained but the scope and duration of litigation stemming from the Seveso case will un- doubtedly be costly and trying for all concerned for years to come. The number of families evacuated from the poisoned zone continued to rise until some 750 individuals were housed in the Residencia Leonardo da Vinci. By October the evacuees, angry and desper- ate at the uncertainty of their situation, one day went out and stormed the barricades, de- manding the right to reoccupy their homes. They were per- suaded to return to the Residen- cia. in the next weeks people began agitating for permission to go into the Seveso cemetery to clean the graves in prepa- ration for All Souls' Day, Novem- ber 2. The area around the cemetery had been declared a military zone and the army maintained a vehicle park near- by. The people were permitted to enter and did so provided with materials for washing and polishing the large flat slabs of marble with which most graves in Italian cemeteries are covered. Nearly all of those who performed this task suf- fered skin rashes afterward and some complained of respira- tory discomfort. A great effort was made by the authorities to clean the schools so that the children could enter them again. The walls were vacuumed and washed with detergents, always by a work force wearing pro- tective clothing, gloves and us- ually masks. After the schools reopened some 200 children developed skin rash. Some of their teachers believe that they have more respiratory ailments and colds than in past years, but this cannot be counted as an epidemiological statistic. The knowledge that TCDD is a potent teratogen fell on the doctors and the public with enormous impact soon after its presence in the poisonous cloud from ICMESA was confirmed. In addition to emergency clinics where more than 10,000 people were examined and given blood and urine tests, a special maternity clinic was established both for counseling and for therapeutic abortion, which the Italian Supreme Court recently declared to be legal in some circumstances. Twenty-seven abortions were performed and the fetal material was sent to a German university for examin- ation by a team of Italian and German specialists. No confir- mation of birth defects was derived from this study. A very stormy period of religious and political controversy arose over the abortion question and the clinic was closed. Some women of the region, who believed they had been too dangerously ex- posed to TCDD to risk bearing a child that might be deformed. went to other countries for abortions in order to avoid the agitation and controversy sur- rounding this issue at home. It is unlikely that any reliable or extensive epidemiological studies of birth defects have been made in any country. In the United States as in Italy, very little data have been kept or compiled in this regard over past years with which new data, for example, relating to a mass exposure to a toxic chemical that is teratogenic. can be com- pared. Continuing research is required and the Seveso case will be a stimulus in that direc- tion. Innumerable meetings of health officials, toxicologists, physicians, and public adminis- tration officers were held in Seveso, Milan, and Rome over the Seveso case. Many foreign specialists were called to Italy on consultation. An Italian team of scientists and administrators came to the United States and met with Americans in special sessions at the Department of State and the National Academy of Sciences. No one could really help very much beyond ex- changing the hard information. There is no antidote for tetra- dioxin poisoning, they had to agree. There is no technological magic with which to counteract or repair the damage done in Seveso to the big physical area touched by the cloud and its drift, and to the segment of human society whose lives were disrupted and certainly in some cases brought to irreparable tragedy. It was only too natural, in the charged state of political ten- sions and economic strain under which Italy has lived for some years now, to accuse public officials of ineptitude or poor performance. In a moment of passion, an angry citizen shot one of the health officials of the Seveso area in the legs. As a matter of fact, the Italian scientific community mobilized rapidly and the doctors worked selflessly in a day-and-night effort to cope with the emer- gency. A pharmacological in- stitute equipped with the expensive, sophisticated instru- mentation for the technique of gas chromatography and mass spectrometry. which are re- quired for the detection and quantification of TCDD, already existed in Milan under highly competent specialists. They were in the Seveso action from the beginning. As the full significance of what had happened began to be appreciated, the government declared Seveso a disaster area, provided assistance funds, and named a special national commission to deal with the problem, under the Ministry of Health. In Seveso, the unfolding situation with all its shocks and complexities involved the four Communal administrations, the Province of Milan, and the Re- gional Giunta of Lombardy. Their ability to get together and steer a relatively straight and basically safe course through the emergency was something of a marvel. An interesting thing about it in retrospect is that despite disagreements or conflicting opinions, or ques- tions of lines of authority, no dictatorial figure seems to have been brought to the surface by the difficulties encountered. Perhaps this was because, in the presence of a massive poisoning of the earth with a chemical so dangerous as TCDD, the alternatives were very limited, and everybody had to come back to exactly what had been done, whether he wished to or not. Not everyone is satisfied that enough has been done. Lax- ness in sealing off and guarding the contaminated zones can be charged. Many will disagree with the recent official estimate of 67 proven cases of chloracne, ascribing the hundreds of other incidents of severe skin irritation to burns from the sodium and methanol content of the fallout. Some people believe that the epidemiological surveys of the general area have been deliberately incom- Continued on page 35 SEPTEMBER 1978 15 ------- . • himnnys nt thr: stern of the Vulcanus mark the location of the incinerator, which destroys toxic is by burning them at extremely high temperatures. Seagoing Furnace Destroys Toxics When the U.S. Air Force began casting about eight years ago for a way to dispose of its surplus stock of Herbicide Orange, the defoliant used in Vietnam, it ran into unexpected problems. Herbicide Orange has been under heavy criticism from sci- entists who warned that the dioxin contaminant in the mix- ture caused birth defects in lab- oratory animals. The Defense Department had ordered the herbicide withdrawn from use in 1970 and the Air Force found itself stuck with about 2.3 mil- lion gallons of it. (Herbicide Orange was a half-and-half mixture of 2, 4-D and 2, 4, 5-T. The latter was banned for a number of uses years ago, and the dioxin was a contaminant from the process used to manufacture it.) One proposal to bury the herbicide in Utah ran afoul of former Governor Calvin L. Hampton, who asked Federal officials to drop the idea. His administration earlier had tried to show that Army nerve gas killed some 6,400 sheep in Utah in 1968, and State offi- cials were understandably leery of the new toxic. Another plan called for diluting Herbi- cide Orange and selling it to South American farmers at cut- rate prices, an idea that en- countered objections by the State Department. The Air Force also met resistance with a draft environmental impact statement proposing to incin- erate the stocks on land in Illinois and Texas. Opponents said this was technically un- sound, environmentally danger- ous and expensive, and the plan was abandoned. Still another major alterna- tive the Air Force pursued, at EPA's insistence, was reproc- essing the herbicide to remove the dioxin by means of special coconut shell charcoal filters. This was tried on a pilot scale in Mississippi, and the experi- ment was successful, but it created a new problem: There was no known way to destroy the contaminated charcoal. In the meantime, however, a relatively new technology for managing toxic substances had been gathering impetus in Eu- rope. German and Dutch engi- neers since 1969 have been using at-sea incineration to destroy organochlorine wastes. (The release of such com- pounds to the environment is undesirable because they are very persistent and can enter the food chain. Even small quantities of some types are acutely toxic.) The technique employed by Europeans to manage such wastes involved specially equipped ships that burned the material at high temperatures in the North Sea. The first of these vessels was the Matthias I, a small tanker of about 1,000 metric tons that had been fitted with an incinerator and was used by a German firm for half EPAJOURNAL ------- a dozen years. A larger tanker of 3,500 tons, the Matthias II, was modified in the same way and is still in service. Then in 1975 the Matthias III, a much bigger tanker of 19,300 tons was modified in a Germany shipyard to perform similar work. Matthias III was designed to carry 1 5,000 tons of liquid waste in its tanks plus several thousand 55-gallon drums on its main deck. However, this ship did not perform satisfac- torily, and rather than invest any further in modifications, the company decided to take it out of commission. But in the meantime the idea of at-sea-incineration already was being examined seriously by several specialists in EPA as a way of disposing of hazardous toxics like Herbicide Orange. These men included John P. Lehman, Director of the Hazard- ous Waste Management Divi- sion; Russell Wyer, who had been Specially appointed by Kenneth Biglane, Director of the Oil and Special Materials Control Division, to study the technology; and Ronald A. Venezia, EPA project officer for environmental assessment of organochlorine waste incinera- tion, Office of Research and Development. The ultimate answer to the problem turned out to be the M/T (for Motor Transport) Vulcanus, a Dutch-owned ves- sel that had been converted from a cargo ship to a chemica! tanker fitted with two large in- cinerators at the stern. Unlike Matthias I and II, the Vulcanus was big enough to operate worldwide. Twin diesels gave her cruising speeds up to 13 knots and she met the require- ments of the Intergovernmental Maritime Consultative Organ- ization (IMCO) and the U.S. Coast Guard for transport of dangerous cargo by tanker. Operated by Ocean Combus- tion Service, the Vulcanus had many safety features, including a double hull with 15 tanks in- side the inner hull to carry the waste liquid. During normal operation the tanks could be discharged only through the incinerator feed system. The Vulcanus had been in- cinerating wastes from Euro- pean countries since 1972 and had acquired considerable op- erating experience. In late 1974 EPA issued a research permit for incineration at sea of 4,200 metric tons of organochlorine wastes from the Shell Chemical Company's plant at Deer Park, Tex. The wastes had been gen- erated during the plant's pro- duction of vinyl chloride and other industrial products. The burn, conducted in the Gulf of Mexico about 150 miles from land, was monitored by two research vessels for pos- sible pollution of surrounding monitored waters and also by a specially equipped EPA aircraft to measure air emissions downwind. EPA granted permission for incineration of another shipload a month later with some correc- tions in monitoring, and in De- cember issued a third permit for incinerating another 8,400 tons of wastes. Based on these tests, the Agency determined that the process did not result in any significant adverse impact on the environment, although some modifications in the ship and its operations were required. Measurements of emissions from the incinerator stacks showed that more than 99.9 percent of the wastes had been oxidized, that is, destroyed, by the intense heat. Observers found no measur- able increases in concentra- tions of trace metals or organo- chlorides in the surrounding sea or in marine life, and no adverse effects on migratory birds. EPA determined that at-sea incineration was a viable alter- native to other means of dispo- sal. When it was found that the disposal of contaminated char- coal canisters was not possible, the go-ahead was given for us- ing at-sea incineration to des- troy the Air Force stocks of the Herbicide Orange. Two-thirds of the Air Force stockpile was stored at Johnston Island, a lonely and remote speck in the Pacific some 850 miles south- west of Hawaii. The other third arrived there on the Vulcanus July 11 last year from storage in Mississippi. One of the most important features of the ship was the very high temperatures that could be generated in the incin- erators. The U.S. permit for destruction of Herbicide Orange called for a minimum operating temperature of 1,250 degrees Celsius (about 2,280 degrees Fahrenheit). But as matters turned out, the temper- ature during the burn actually approached 1,500 Celsius (2,732 Fahrenheit), hot enough to melt steel, and more impor- tant, also hot enough to destroy the toxic materials. In fact Herbicide Orange burned so well that operators had to throt- tle back on the flow to keep the heat from destroying the furnace. Along with the cargo, the ship carried a special portable lab- oratory on her deck just for- ward of the bridge where spe- cialists could study samples and monitor instruments. Ela- borate precautions were taken to assure the safety of the crew as well as of the surrounding environment. In addition to nor- mal equipment, for example, all personnel within the inciner- ator area had gas masks avail- able for instant use and those exposed to high temperatures wore fire-fighter entry suits. Pesticide gas respirators, port- able monitors, Scott air packs and even portable emergency eye baths were on hand. No workers were allowed to enter the incinerator area without wearing disposable protective clothing, and upon leaving they had to throw the clothing into a barrel, take a shower, and don fresh coveralls. Contents of the barrel were routinely incinerated. Fortunately, emergency equipment was never needed. In three separate burns about 1,000 miles southwest of Hawaii in July and August last year, the Air Force supplies of Herbicide Orange were care- fully incinerated without mishap. Instruments measured com- bustion effluent, and the crew took wipe samples of selected areas on the ship to confirm that no traces of the herbicides found their way into living areas. In a mop-up operation, each of the tanks that had stored the herbicide was rinsed with diesel oil which was then incinerated. In its official report to EPA on the operation, TRW, Inc., which performed monitoring, sampling and analysis to assure compliance with the EPA per- mit, declared, "Destruction and combustion efficiencies meas- ured during the Research and Special Permit burns met or ex- ceeded requirements. All other conditions of the permits re- lated to at-sea incineration operations were met, including adherence to a comprehensive safety plan." The significance of the John- ston Island project, however, extended far beyond destruc- tion of the 10,400 metric tons of Herbicide Orange. According to Lehman, some 30 to 40 mil- lion metric tons of toxic waste are produced annually in the United States, and the volume is steadily increasing. At the same time, disposal has become more difficult be- cause of increasingly stringent controls in the new Resource Conservation and Recovery Act to protect the environment. Long-term storage of these wastes in above-ground tanks is unsatisfactory in many cases because of the potential for leaks, accidental ignition, and spills from natural disasters such as earthquakes. So the at-sea incineration offers another approach to dis- posal of these potentially dan- gerous by-products. Although only about half of the annual output of hazardous waste is organic and amenable to in- cineration, the experiments demonstrate that under appro- priate safeguards, at-sea incin- eration can be managed safely. As an indication of growing interest by both government and industry in this relatively new procedure, the U.S. Mari- time Administration has com- missioned a cost study by Glo- bal Marine, (builders of the Glomar Explorer), of ship con- version for future incinerator vessels. It is believed there are enough wastes to support the operation of four such ships under the U.S. flag. If true, then an infant industry in safe, sea- borne waste disposal appears to be in the making. D SEPTEMBER 1978 17 ------- The Challenges in Environ- mental Health An Interview With Dr. David P. Rail, Director, National Insti- tute of Environmental Health Sciences Could you explain briefly the mission of NIEHS and how it differs from other organizations, such as EPA, the National Cancer Institute, and so on? Let me point out first that we are part of the National Institutes of Health and I think that's the key to understanding how our mis- sion is different from the more regulatory-oriented agencies like EPA, or FDA, or OSHA, or NIOSH. We try to understand in basic biomedical terms how environmental chemicals act to produce their damage to human health. We are basically inter- ested in mechanisms. Now I know that some people think that studies on mechanisms are ivory-tower and basically irrele- vant to the urgent needs of regulatory agencies. But it seems to me they are the neces- sary backup for effective, well- balanced regulatory action. Stephen J. Gould, a brilliant Harvard scientist, discussed some years ago the fact that scientists are reluctant to deal with data, even though the data seem very solid and reliable, if they don't understand the basic mechanism that appears to be producing the data. He cited as an example the fact that for decades it's been known that the West Coast of Africa and the East Coast of South Amer- ica fit almost perfectly, like a jigsaw puzzle cut-out. But sci- entists refused to accept this fit because they couldn't under- stand how these two continents could have belonged to each other at one time when they are now over a thousand miles apart. When the theory of plate tectonics came along, the theory that continents are on shifting, floating plates and can move and bump against each other and come apart, all of a sudden everybody said those data are nifty. Let's believe them. But what the scientists needed was the mechanism, the understand- ing of why the data were there in the first place. That is what I call the comforting dogma— that scientists like to be able to understand what's going on above and beyond just getting data. Mechanism studies have an- other great importance to regu- latory agencies. For instance, they provide the basis for devel- oping rational, short-term tests for toxicity. One of the prob- lems in regulating for human health protection is that our standard toxicity tests take lit- erally years, are extremely expensive in terms of dollars and scarce professional staff, and frankly are still at a pretty crude stage. What we hope to do with our mechanism data is to be able to develop much more precise, meaningful tests for chemicals for predicting human toxicity in much shorter time frames. In addition to this basic research, which is really the essence of NIEHS, we do short- term research. We are inter- ested in pragmatic problems. We have a large study under- way on the toxicity of asbestos ingested orally, which grew out of the Reserve Mining Com- pany's Lake Superior case. We are supporting an excellent epi- demiological study at Harvard University on air pollution levels and human health. We feel that an imaginative mixture of the basic mechanistic re- search and relevant real-time research, (meaning directly relevant to PBB's and similar problems) is the most effective way to make the Institute strong and exciting. We are different from the other agencies also because we deal with the entire spectrum of environmental problems, whether they be in the air, the water, or the workplace, or whether they be a result of a mixture of a therapeutic medi- cine and an environmental pol- lutant. So our mandate is broad: to look at all aspects of those chemicals that can come in con- tact with people and might dam- age human health. In addition to chemicals we have small programs on non-ionizing radi- ation research, (i.e., microwave effects) which I think will be increasingly important in the future, and on the harmful effects of noise. Our current budget is around $65 million. We haveabout 366 full-time employees, and with the part-time and post-doctoral students, and so on, over 500 people work at our Institute every day. How many mice and rats does your lab keep on hand for tests? About 20,000 in our current excellent animal rooms. We are building a new facility across the street on a portion of 500 acres of land the Research Triangle Foundation gave to the U.S. Government that could have up to 1 20,000 mice or rats. When those quarters are finished—they should be ready in 1980—we are hopeful that this will let us expand our pro- gram significantly. Our new building is on an artificial lake which we will begin to fill in a month or so, and there is a lovely site across the lake from our building in the pine trees that's reserved for the Environ- mental Protection Agency. You mentioned two studies—oral asbestos, and the noise study. Are either of these being done in cooperation with EPA? We work closely with EPA on the noise, but there is no direct collaboration. I am pleased that EPA is contributing to the cost of the oral asbestos experi- ments, and I think it is another example of how we do work very closely with the regulatory agencies on matters of urgent regulatory need. That study was designed by an interagency group with NIEHS, EPA, FDA and other scientists. At one time in your career you were very active in the National Cancer Insti- tute in the use of chemo- therapy to meet the can- cer challenge. Why did you change course and take the environmental route? Well, I hope it was a well thought-out philosophical change in course. As I began to look at the toxicity of anti- cancer agents I began to be concerned about how to pre- dict for toxicity. Not for one or ten or a hundred patients, but hundreds of thousands to mil- lions of people, and it seemed to me that a totally unsolved problem at that time, which was close to ten years ago, was the concept of population toxicity: I 8 EPAJOURNAL ------- An artist's rendition Park, N.C. of the National Institute of Environmental HenHh Science building under construe) h Triangle What about the danger of a chemical to which many if not most people in the country are exposed? How do you predict or project the toxicity to this enormous spectrum of well people, ill people, males, fe- males, young, old, those on good diets, those on bad diets? And this concept of population tox- icity began to intrigue me, and that is really what led rne down to North Carolina and the Na- tional Institute of Environmental Health Sciences. With enactment of the Toxic Substances Control Act we have discovered there is a woeful shortage of toxicologists. Can you explain why that is and the NIEHS role in helping train new ones? The Office of Management and Budget decided in the mid- 19 60's that we were training too many biomedical scientists and I happen to think there was some truth in that judgment. Unfortunately they did not look at some of the smaller special- ties within the biomedical sci- ences and as they cut back all training programs they also cut back our training program for environmental toxicologists, epidemiologists, and patholo- gists. In fact in 1975, our train- ing budget had fallen from about $5 million a year to $1.7 million, and we were literally being phased out. I was very concerned about this. The sci- entists at EPA were very con- cerned about it, and with help from the Administration, Con- gress put an extra $3.5 million in our 1976 budget and we are now atabouta $5to $5.5 million a year level for training toxicologists and scientists in other fields. This will help. The Conservation Foundation, with support from EPA and NIEHS, held a meeting to look at toxi- cology and toxicology training. They project a need for an addi- tional 1,000 toxicologists over the next three or four years with modest continued support after that time. Our training budget for the next fiscal year has not been authorized or appropri- ated, but we are hopeful we will be able to train even more toxi- cologists in the future. The shortage is very real and very dramatic, and its continuation can have nothing but dire conse- quences for the Federal regula- tory program as well as for industry, which increasingly wants to ensure that the chemi- cals it produces are safe. We understand that NIEHS was instrumental in funding work by a physician, Dr. Philip S. Guzelian, at the Medical College of Virginia to help remove Kepone from the bodies of workers at Hopewell during the Kepone crisis. Can you describe that and comment on your organi- zation's ability to meet future crises of this kind? This was really very exciting. We were, of course, aware of the Kepone problem and I got a phone call from Dr. Guzelian, who said, "You know, I have most of the Kepone patients on my service at the Medical Col- lege of Virginia." Dr. Guzelian had been trained as a physician, an internist, and a pharmacolo- SEPTEMBER 1978 111 ------- gist, and he said, "We Think this would be an unparalleled opportunity to look at the phar- macokinetics, the fate and dis- tribution and excretion of this chemical in these twenty or thirty people and try to see if we can develop mechanisms to help them rid their bodies of Kepone." We were able to get a sole-source contract for Dr. Guzelian to get his work started. This was truly sole-source, since he had all the patients that were ill of this particular disease. We got that funded within two or three months, which is probably a record. He then applied for a standard NIH research grant through us and that was funded, and he now has a long-term project sup- ported by our grants mechanism to look not only at Kepone but the possibility of eliminating other agents. His project was successful. He discovered, which had not been known before, that a sig- nificant amount of the Kepone appears to be excreted in the bile, or at least somewhere in the gastrointestinal tract and that if you administer a binding agent, called cholestyramine, this agent can bind the Kepone, prevent it from being re- absorbed into the body, and you can increase the excretion about seven-fold. He has done this in a double-blind study and not only do the chemical levels of the Kepone go down in the bodies of the patients, but their symptoms are going away. They are becoming less sick. This, to me, is one of the great success stories of well-applied basic research in the environ- mental field. Assuming that we might have another Kepone-type crisis in the future, do you have a mechanism within your organization to give a quick grant to an institute for research? A quick contract under certain circumstances. The contracting procedure is now very complex and, as a matter of fact, if you cannot fulfill the narrow defini- tion of sole-source, it becomes very difficult to rapidly fund people doing research of high urgency in a critical area of environmental health. And I think we should look for new means to develop the rapid support mechanism. Do you think it would be useful for the government contracting procedures be modified so that agencies like yours can grant money to re- searchers rapidly? I think it would be wonderful if there could be a mechanism whereby the various agencies involved in environmental health, such as NIEHS, EPA, and some of the others could have access to a small contin- gency fund each year which could be used very rapidly to explore situations where there are real human health problems and it is important to move rap- idly to study and solve them, such as Kepone, PCB's, and the PBB problem in Michigan. On that subject, are you comfortable with the laws now in place to control environmental hazards, or do you believe there should be amendments or new laws? I think now we are really in pretty good shape. The Toxic Substances Control Act is really a landmark law. It is extraordi- narily complex, as I am sure everybody at EPA understands. I guess I am conservative enough to suggest that I would like to see how implementation of the Act works before we rec- ommend any drastic changes. If you took back over the last ten years, the growth of the ability of the government to regulate toxic chemicals, other than food additives and drugs, has gone from about zero to potentially close to one-hun- dred percent, This is a dramatic accomplishment and I think having bitten off this large mouthful, we probably ought to try to digest it and see how it works before we talk about new legislation. The Act will require much more testing of toxics in laboratories, but industry often has ques- tioned the validity of comparing results of tests on mice to the cancer hazards of a chemical to humans. Can you com- ment on this? Well I am very concerned about that argument for basically two reasons. The first is almost a moral issue. If you don't test chemicals in laboratory animal situations you have no choice but literally to test them on the human population, to make the people exposed to the chemi- cals "guinea pigs," which means you have to have (if a chemical is toxic) a full round of human diseases, and pos- sibly, death and/or disability, before we know that chemical is toxic and can take appropri- ate regulatory action. It seems to me modern society cannot, will not, and should not accept using society itself as the test animal. The alternative is to use laboratory animal tests to pre- dict the toxicity and then take regulatory action on the basis Dr. Philip S. Guzelian of the Medical College of Virginia, who has done extensive re- search in toxicology, developed ,1 method for treating Kepone victims. of that prediction. I think the evidence is increasing that laboratory animals predict very well—not perfectly, but then nothing in biology is perfect— for toxicities in the human pop- ulation. It has only been recent- ly that we have begun to take a hard fook at the results of lab- oratory animal tests and the results when the human popu- lation is inadvertently exposed to the same chemicals. Fortu- nately the latter doesn't happen that often. We are finding that the results are surprisingly similar. The International Associa- tion for Research on Cancer at Lyons, France, has now looked at close to 400 chemicals for carcinogenicity. With roughly half of them, they feel, there is evidence at the animal level for carcinogenicity, but with most of those there is absolutely no information one way or the other as to whether these chem- icals are carcinogenic in peo- ple. On the other hand, for 26 of them there is clear evidence that the chemicals are carcino- genic in humans. Now six of those are unknown chemicals from industrial processes, and in each of those industrial processes laboratory animals have identified carcinogenic components. So that for those six, there is a good relationship between animals and humans. For 1 6, there is also a clear positive effect in laboratory ani- mals, and a clear positive effect in people. There are four left where there is reasonably good evidence at the human level. For two of these, arsenic and benzene, there is beginning evidence at the animal level that arsenic may be a co-carcin- ogen and there are two studies with benzene, as yet unpub- lished, that show it probably is a carcinogen in animals. The other two are chemicals which simply have not been tested in animals yet. So that suggests there is really very good con- cordance between laboratory animals and human results. I think we can begin to put more confidence in animal tests. 20 EPAJOURNAL ------- Can you explain the Ames Test for the general public? The Ames test uses bacteria which have been genetically engineered to be very sensitive to mutations. Mutations are a way of descrjbing what hap- pens to the DNA, which is the way life reproduces itself with fidelity. A mutation occurs when that process is messed up. The reproduction from mother-cells to daughter-cells is no longer proper. There is a change, and that change is mutation. Most scientists now believe that most cancers have an origin in a mutation in a cell in the body somewhere, due either to chemicals or to ioniz- ing radiation, or to ultraviolet radiation. That is the so-called initiating event in the cancer process. It is likely that other things may have to happen for that to develop into a clinical tumor or cancer. The initiating event is the disturbance of the DNA in trying to send informa- tion from one cell to the next, and that is called a mutation. These bacteria have been de- signed so that they pick up in a very simple way these mutations. Is the Ames test chiefly useful to your laboratory as a quick screening or has it broader value than that? I think the Ames test will have enormous value. We use it all the time. There are problems with it right now, which I don't think are well appreciated. The problem is there is no one Ames test. The specifications of the test, which strain of bacteria, details of the nutrient broth, details of adding the micro- somal mixture are still flexible and are still being studied. It is going to be very useful, but we need to begin to apply quality control procedures to the Ames test to standardize it in one of three or four or five forms and then begin to do this very care- ful comparison between the results using chemicals in the standardized Ames test as well as in laboratory animals, and from what we know, in people. A good example of what 1 am talking about is the fact that initially the Ames test was neg- ative with respect to saccharin. As you adjusted the conditions of the tests, made changes, you showed that under certain cir- cumstances saccharin could become positive in that particu- lar Ames test. So I think with the Ames test and a number of the other very promising assays, like sister-chromatid exchange, and some of the others, we need to standardize them. We need to do the testing of the test to see how predictive it is. I think it has a great future. Is NIEHS now doing tests on saccharin, and if so, does it appear now that it is the impurities in the saccharin that are the carcinogens? No, 1 don't think we are. A lot of other laboratories are. It is still intensively being studied and the saccharin story is fascinat- ing. The so-called Canadian study really was not addressed to whether saccharin caused cancer in the bladder of rats. That had really been well estab- lished in two or three previous studies. The problem it ad- dressed was the fact that there was at that time, and probably still is, a contaminant in saccha- rin, orthotoluene sulfanomide, which many people thought was the carcinogen. The Cana- dians spent most of their efforts trying to determine whether the contaminant was a carcino- gen. The importance of their study was that the contaminant clearly was not a carcinogen, in a well-designed, well-con- trolled test. This immediately validated the two previous positive American studies for saccharin. The Canadians also threw in another group of ani- mals given saccharin that in fact absolutely duplicated the two previous American studies. There are still probably other contaminants in saccharin and they are being intensively studied, and I must say today I don't know whether one of these contaminants is the mutagen-carcinogen, or whether it is saccharin itself. Do you think it would be useful to merge the var- ious environmentaHy re- lated agencies such as yours, EPA, and the en- vironmental functions of others, such as the Food and Drug Administration, or are they more effective as separate independent bodies? 1 think you can make good argu- ments one way or the other. I have been impressed as I have lived within the bureaucracy that there is importance and strength to diversity. Each of the agencies really has a unique mission and needs the opportu- nity to focus on that mission. Whereas FDA is concerned about drugs and food additives, EPA is concerned about air pol- lutants and water pollutants, pesticides and toxic substances and, although many of the techniques and the methodol- ogies are different, there needs to be a focus on the particular chemicals of concern. I think the diverse organization allows for strength in focusing on par- ticular concerns. At the same time, I feel there needs to be much stronger coordination and information exchange be- tween the relevant agencies, and this has moved a long way in the last six or seven years. Within HEW we have the Com- mittee to Coordinate Toxicol- ogy and Related Programs, which has had EPA representa- tives on it since Day One, The Interagency Regulatory Liaison Group is now functioning very effectively. So I think I would recommend diversity but with effective coordination of the various agencies. Recently you expressed some concern over the amount of cadmium in the environment and its effect on humans. Do you think we need an EPA standard on this and a curb on its use by the Defense De- partment and others? i think it's a little early to pro- pose a standard. I think we still need better information on emission sources. We need better information on the trac- ing of cadmium through the environment and how it ulti- mately gets to human beings. I think we need that information fairly urgently and I don't think we are quite at the stage where we know how to control cad- mium. We need the information dealing with how it moves from its production and use through the environment to people be- fore we can find those critical areas in that flow of cadmium that can be controlled. In what way is cadmium hazardous to humans? There is some evidence that it may cause cancer of the pros- tate. It does damage the kid- neys and it is implicated in causing hypertension. With hypertension being one of the major killers today, it could have enormous importance, but I don't think we know quite enough about it to talk about standards. I think we need to learn quite a bit more about its effect on people and how it reaches them. What do you see as the greatest challenge in en- vironmental health in the next decade? I think it is what I talked about earlier. Developing and validat- ing a series of efficient tests using laboratory animals or laboratory systems so that in a reasonable length of time, and with a reasonable amount of money we can look at a new chemical and suggest that it will likely be safe when it is put into the environment by what- ever commercial process is used. I think that is the urgent need—to develop predictive tools for chemical toxicity. [ ] This interview was conducted by Truman Temple, Associate Editor of EPA Journal. SEPTEMBER 1978 21 ------- Wanted: More Toxi- cologists Environmental health legis- lation, particularly the Toxic Substances Control Act, has created major new de- mands for lexicologists. How many are there at present? How many are needed? Is there a gap between need and supply? To find out the answers, the Conservation Foundation or- ganized a workshop with repre- sentatives from the chemical industry, environmental organi- zations, Federal and State agencies, academic institu- tions, and the press. Results of their discussions were pub- lished last April in a report, "Training Scientists for Future Toxic Substance Problems." Sponsors of the workshop were EPA, the National Institute of Environmental Health Sciences (NIEHS), the Chemical Industry Institute of Toxicology, and the Foundation. According to the report, it's estimated that about 5,000 professionals now work in the field of toxicology. There is an immediate need for about 1,000 additional professionals, of whom 500 would be senior professionals with doctoral or postdoctoral training in toxi- cology. Some consider these projections too conservative. But in any case, they suggest the magnitude of the problem. One thousand additional tox- icologists may not appear to be a very large figure, but it repre- sents about 20 percent of the present professional work force. In addition, there is a continuing need for new men and women to replace those who leave each year because of retirement, career changes, and so on. It's estimated that this replacement need is about 200 professionals each year, or half that number of senior professionals. NIEHS is the major institu- tion through which training grants are made in toxicology and other environmental health sciences. The number of pre- doctoral and postdoctoral NIEHS grants (including re- newals) declined from 409 dur- ing Fiscal Year 1971 to 194 during 1976. The 1977 figure is 331. Predoctoral training requires an average of about three years to complete (three to four years after a bachelor's degree or two to three years after a master's degree); post- doctoral training takes an aver- age of about two years. So the 1971 level of trainee support through NIEHS, if continued, would produce about 1 50 new senior professionals per year orabout 135 peryearforthe 1977 figure. "Such statistics confirm that current training programs are inadequate to cope with the anticipated bulge in demand," the report declared. "This shortfall is a serious national problem that deserves prompt, high-priority attention, both by infusion of adequate training funds and by a variety of other strategies. . . ." The problem of expanding toxicology training programs, while critical, is strictly limited, both in size and time. The re- port warned that it would be unfortunate to set up training programs that ignore the lim- ited nature of the need and produce an excessive number of highly trained specialists, a situation that occurred in train- ing aerospace engineers in the 1960's. "There is a very large price to pay for not giving priority to funding of toxicology training: that price is mistaken decisions by government and industry about the marketing and use of chemicals," the report empha- sized. "Decisions on environ- mental contaminants, toxic chemicals, and other environ- mental health issues will be made regardless of the level of knowledge and professional skill brought to bear on them, because, through legislation, the public demands it. If train- ing is inadequate in quality— or if insufficient numbers of trained toxicologists are avail- able—the price for society can be enormous. Not only are poorly conceived and adminis- tered chemical testing pro- grams expensive, but the cost may also be measured in lives or jobs unnecessarily lost." Recruitment Conferees at the workshop agreed that recruitment of out- standing trainees is essential in meeting the need for good toxicologists. The challenges and rewards of a career in en- vironmental toxicology may not be known or appreciated by the public. Recruitment of trainees also appears to have suffered from widespread ad- verse publicity involving the reliability of test results in a few situations. Steady funding is critical both for trainee sup- port and for continuity in devel- oping competent and respected training centers, they noted. Professional Challenges The study of environmental contamination problems— whether the effects of chemi- cals on animals or people or the movement of contaminants into the human food chain—offers intellectual and professional challenges, the report declared. "Toxicology also has a strong moral appeal as a career with clear potential for social benefit in its concern with pre- vention of disease and dis- ability. And toxicologists have the opportunity to see their work used in the social judg- ments applied to toxic chemical questions—for instance, risk/ benefit analyses and other kinds of decision making," the report stated. From a purely practical view- point, toxicology was high- lighted as an attractive career because TSCA and other new laws have created many pro- fessional opportunities. The conferees suggested that toxicologists have the opportunity to spread a sense of excitement about the pro- fession, directed toward other professions, undergraduate, graduate and high school stu- dents. While this could over- stimulate interest and lead to over-expansion if carried too far, the need for new toxicol- ogists is great enough to war- rant a major effort, the report said. Professional societies have a real opportunity to increase public awareness of toxicology as a profession, and they should consider holding meet- ings with chemists, pharma- cologists, and other associa- Contmued on page 37 22 EPA JOURNAL ------- Controlling Toxic Substances Continued from page 6 could do much in the future, to prevent such'errors, per se. The possible exception to this is that TSCA gives us the au- thority to require special label- ing of toxic chemical contain- ers transported or otherwise used in commerce. We now are developing a labeling provision under TSCA. If such a provision had been in place at the time, the Michigan PBB tragedy might have been prevented. Kepone, of course, involved willful violation of existing law. TSCA will enable us to identify those areas where Kepone-like substances are being produced; we will be able to alert regional and State officials that a danger- ous chemical is being produced at a given site, and that they may want to do some monitor- ing to see if any of it is escap- ing into the environment, so in that sense, TSCA will help. But neither TSCA nor any other law can be effective in the case of willful violations. Are you comfortable with TSCA, or are there some improvements or amend- ments you would like to see? Well, I think we need to have a little more experience working with the Act before we start talking about amendments. But when we have some experience under our belt and learn that some parts of the Act may not operate the way we think Con- gress intended, we certainly will approach Congress about amending it; it's just too early to do so now, however. Is it fair to characterize TSCA as a law that covers some of the loop- holes in the other laws, plus gives us a broader authority? Yes, that's a good way of put- ting it. It's both an umbrella and a gap filler. It covers a whole series of other laws, and at the same time fills in the gaps among them. What about "turf" prob- lems with other agencies? Since some other agencies also regulate toxics, do you foresee jurisdic- tional disputes? There are a couple of things that can be said on this subject. One, of course, is that the other chemical regulatory agencies— OSHA, FDA, and the Consumer Product Safety Commission— have joined EPA as members of the Interagency Regulatory Liai- son Group. The very reason for this group's existence is to avoid turf problems, and to take advantage of common knowl- edge and develop consistent approaches to dealing with chemicals. Considerable effort is going into this group to help us work together more effec- tively. I think this has been very successful. The other thing is that Con- gress recognized that there are potential overlaps among TSCA and toxics-related portions of other statutes, and that these overlaps should be avoided. So section 9 of TSCA requires us to defer to other agencies or to other laws, if deferral repre- sents the best way to deal with the problem. We can't just move in and poach on someone else's territory. We are obligated to assess the problem and then to decide whether the most effec- tive solution is through TSCA or some other law. Congress was sensitive to that, and pro- vided a mechanism within TSCA for avoiding problems of this kind. Getting back to some of the international aspects of toxic substances con- trol, is there a mecha- nism within TSCA to handle chemicals im- ported from other countries? Yes. As I mentioned earlier, importers are treated the same under TCSA as domestic manu- facturers. This is why there is so much international interest in TSCA. Any regulation that we promulgate for the U.S. market applies to foreign importers, as well. If I am a Japanese ex- porter and I'm bringing in a boat-load of arsenic, what will U.S. Customs officials at the dock do? Assuming that we had decided to regulate arsenic, they would be on the lookout for arsenic shipments. EPA's own enforce- ment people would too. If Japa- nese or any other foreign manu- facturers develop some new chemical, we will have arrange- ments with customs and our own enforcement people to as- sure that the chemical is not introduced without proper noti- fication under TSCA section 5. Is there any way to con- trol our exports of toxics to protect other countries? Congress decided that it wouldn't give us the authority to prevent the export of chem- icals that we think are too dan- gerous to be used in the United States. The only way we can deal with that is if the actual production of that chemical for export purposes poses such a risk that the chemical should be banned within the U.S. How- ever, TSCA directs us to notify foreign countries if chemicals we have acted against are being exported. Congress decided that it's not appropriate for EPA to tell a foreign country that it should not use a chemical, but it is entirely appropriate that we tell them what we think the problems are with the chemical, and let them make up their own minds. The pesticide law is very similar to the toxics law in this respect, I might add. TSCA has some very powerful penalties, in- cluding up to $25,000 a day and a year in prison for some violations. Is there any way to assure the small chemical com- pany official that he or she won't be put in leg irons for some minor in- fraction under TSCA? I can't speak directly for the Assistant Administrator for Enforcement, but I think we will take a common-sense approach to enforcing the Act—one that is firm but also recognizes that there may be unique situations that don't require as stiff or stringent approaches as others. That characterizes EPA's en- forcement program generally —-tough but realistic, sensitive to special concerns. The public is hearing so many stories these days about everything causing cancer—like the recent story on fried hamburgers as carcinogens. Is there a danger they may not be- lieve us any longer? Are you worried about whether the public will stop supporting the effort to control toxic chemcials? This is a real problem, and a real concern to me personally. There are a couple of aspects to it. One is that it appears the public wants to make its own risk-benefit decisions in situa- tions where individuals have personal control—such as smoking, using saccharin, or even eating hamburgers. EPA, though, is concerned about in- voluntary exposure to chemical risks that are unreasonable. The public has generally shown that it doesn't want to be exposed to risks it doesn't necessarily benefit from or have any direct control over. There's a big dif- ference between exposure to a naturally-occurring risk, such as aflatoxin, and exposure to risks that do not occur naturally and are introduced by human activity. By definition, one has to live with some naturally oc- curring risks.

SEPTEMBER 1978 23 ------- Sharing Environ- mental Knowledge with Japan By Kirk D Maconaughey Ihe U.S. Government will ' host the Third Annual Joint Planning and Coordination Committee Meeting this month with Japan, a country that led the world in enacting broad toxic substances control legis- lation. Deputy Administrator Barbara Blum assisted by Alice B. Popkin, Associate Adminis- trator for International Activ- ities will be the U.S. Chairman at the September 11-13 meet- ing, which will be held at the Department of State. Blum led the delegation at last year's meeting which was held in Tokyo. Hisanari Yamada, Di- rector General of Japan's Environment Agency, will lead his country's delegation. Although formal cooperation in environmental matters dates back to August 5, 1975, when the bilateral environmental agreement was signed, the United States and Japan have enjoyed a much longer history of working together. Consider- ing our close political and eco- nomic ties with Japan, and the fact that we face many common environmental problems, it is not surprising that cooperation in this and related areas dates back many years. In 1964, for example, the two countries established the US-Japan Cooperation Program in Natural Resources. It was from this program that the Environmental Agreement Kirk Mnconaughey is the U.S. Executive Secretary for the US- Japan Environmental Agree- ment and is n member of the Office of International Activities. emerged. Informal cooperation on environmental topics also has been pursued at other levels. In 1971, Russell Train, at that time Chairman of the Council on Environmental Quality, met with Japanese officials to discuss ways in which the two countries could broaden the scope of their environmental cooperation. In the context of these discus- sions, regularly scheduled, high-level meetings were ar- ranged for the purpose of exchanging technical informa- tion. With the establishment of the bilateral agreement, these meetings have been expanded and are now called the Joint Planning and Coordination Committee Meeting. The pur- pose of the Joint Committee Meeting is to discuss major environmental policy issues relevant to both nations, to coordinate and to review activi- ties under the Agreement, and to make necessary recommen- dations to the two governments to implement the Agreement. The US-Japan Agreement is one of nine bilateral environ- mental agreements in which EPA participates. These envi- ronmental agreements are in turn part of much broader science and technology agree- ments between the United States and other nations. Under the broad science and technol- ogy agreement between the United States and Japan, there are nine separate agreements, the Environmental Agreement being one of the most active. Japan—World Economic Power Japan has been called the world's most rapidly changing society. Although somewhat small in terms of land mass, there can be no mistaking Japan's importance in the world economy. Over the past quarter of a century, the country has successfully mounted an indus- trial and development campaign which has made her the world's third largest economic power. This same tremendous indus- trial and technological surge which has resulted in Japan's recent prosperity also accounts in part for her environmental problems. To begin dealing with these concerns Japan established its Environment Agency (EA) in 1 971. EA has the task of setting and implementing the country's Projects Sewage Treatment Technology Management of Bottom Sediments Containing Toxic Pollutants Identification and Control of Toxic Substances Air Pollution Related Meteorology Photochemical Air Pollution Stationary Source Air Pollution Control Technology Automobile Pollution Control Solid Waste Management Health Effects of Pollutants Technology for Closed Systemization of Industrial Waste Liquid Treatment U.S. Chairman Frank Middleton MERL-Cincinnati, Ohio Dr. A.

In addition to these respon- sibilities, EA administers na- tional programs in the areas of nature and park conservation. Over the past seven years, EA has worked diligently to im- prove japan's environmental quality.'Major programs have been enacted to improve pollu- tion controls in both air and water. A significant percentage of Japan's pollution abatement technology is directed towards four major categories: desulfur- ization, dust collection, indus- trial wastewater treatment, and sewage treatment equipment. Great strides have been made in reducing pollution levels of sulfur oxides and nitrogen ox- ides. In 1976 the Organization for Economic Cooperation and Development (OECD) com- pleted a survey on the environ- mental policies of Japan. In its report OECD stated that Japan has established a successful environmental program. Im- pressive pollution/abatement programs have been success- fully introduced and pollution trends have been reversed. In such areas as air quality and toxic chemicals, the OECD con- cluded that environmental quality has greatly improved. Information on Toxics Much useful information has been exchanged at the US- Japan Joint Meetings in the past three years. It was in these sessions that we learned first- hand of Japan's experiences in controlling PCB's under its new Chemical Substances Control Law. At the second meeting, the two countries discussed respective experiences in deal- ing with and implementing na- tional toxic substances control legislation. In addition to policy level discussions each of the individ- ual projects under the Agree- ment is reviewed during the meeting. EPA, the State De- partment, and the President's Council on Environmental Qual- ity (CEQ) are the principal U.S. agencies that participate. EPA has primary responsibility for managing ten projects.

Continued on page 33 .'.'I EPAJOURNAL ------- Environmental Almanac: September 1978 A Glimpse of the Natural World We Help Protect The Death Daisy Farmers in the mountainous areas of Kenya in equa- torial Africa are now busy harvesting as many flowers as they can from the pyrethrum plant, a member of the chrysan- themum family sometimes re- ferred to as the "death daisy" because of its effectiveness as an insecticide. At present there is a short- age of pyrethrum because there have been unusually heavy rains in Kenya, the main pro- ducer. Kenya normally has two rainy seasons, a short one in May and June and a long wet winter. As a result the thousands of farmers who grow this flower on small plots are trying to harvest as many of the blooms as possible before the arrival of winter. After being picked, the flowers are dried in the sun. A flower extract is then shipped to the United States and other countries. The powder ob- tained from the dried flower heads provides the potent insecticide. Another factor contributing to the current world shortage of natural pyrethrum is that the prices of coffee, tea, corn, and other crops raised in Kenya have gone up more swiftly than the government-controlled price for this natural insecti- cide. However, pyrethrum is still one of Kenya's main agri- cultural export crops. In addition to the approxi- mately 85,000 farmers in Kenya who raise pyrethrum, there are farmers in Tanzania, Rwanda, Zaire, New Guinea, Ecuador, Brazil, and Japan who grow this flower. But Kenya has dominated the world market. Pyrethrins, the bug-killing substance obtained from the flower, are practically non-toxic to warm-blooded animals but have a very rapid "knock- down" effect on many insects. The pyrethrins break down quickly when exposed to light and their effect is fleeting. They can be stabilized, how- ever, and their effect intensi- fied (synergized) by the addi- tion of piperonyl butoxide and other compounds. Although the flower is often grown for its decorative value in the United States and many other countries, the plant will produce satisfactory amounts of the insecticidal substance only if grown under certain conditions. Effective generation of the pest-killing chemical is only assured if the plant is grown in a nearly continuous Spring-like climate with no frost and with nearly equal day and night intervals, conditions found in the uplands of Kenya. Attempts made to grow pyrethrum as a commercial crop in Colorado and other locations in the United States have been generally aban- doned. In addition to the exacting climatic conditions required to grow pyrethrum for its pesticidal uses, the high cost of the labor needed to pick the flowers just at the right time has also discouraged attempts to grow it in the United States. The commercial use of pyre- thrum is believed to have origi- nated in Persia. The fame of these peculiar flowers spread after someone noticed dead insects surrounding flowers which had been discarded after they withered. The pyrethrum insect pow- der was first imported into this country in 1 860, according to a book "Pyrethrum, the Natural Insecticide," edited by John E. Casida. This work contains an evalua- tion of pyrethrum by Emil M. Mrak, a noted scientist. Mrak said that pyrethrum is one of the earliest insecticides and "con- trols certain insects as effec- tively and more safely than most of the currently used synthetic organic insecticides. There is no evidence of harm to humans, domestic animals, or wildlife, when used as directed." The shortage of natural pyrethrum has helped to stimu- late interest in the pyrethroids, man-made imitations of this natural pesticide. Last summer EPA gave emergency permis- sion to 14 States to allow cotton farmers to use five experimental insecticides, including three new pyrethroids, to help com- bat serious outbreaks of de- structive caterpillars. Approximately 4,000 of the 35,000 pesticides registered with EPA contain pyrethrum or synthetic pyrethroids. Hopes that the natural pyre- thrum could replace many dangerous pesticides have not been fully realized because of growing problems, cost and efficacy factors. At- tempts to fully duplicate this natural product have not been successful. Scientists have reported that pyrethrum is so complicated a substance that it has evaded complete analysis. They have noted that its very complexity may be responsible for the in- ability of insects to develop resistance to it.—C.D.P. fl SEPTEMBER 1978 25 ------- Curbing Chemicals in Drinking Water By Victor J. Kimm Are organic chemicals in the Nation's drinking water a cancer risk or not? EPA says they are. The water- works industry generally says such dangers are unproven. EPA set off the debate last February when it proposed regulations to start limiting the amount of organic chemicals in drinking water. The controls would initially apply to public water systems serving over 75,000 people. The waterworks industry has generally opposed the standards. The cancer risk question is the critical one for EPA. Under the Safe Drinking Water Act, the Agency must set standards if there is such a health danger. The objective is to reduce the risks to the extent feasible. In proposing the standards, EPA is convinced the risks are there. The Agency feels that organic chemicals in drinking water pose a big enough health problem to justify action under the law. EPA realizes though that details of the proposed rules may be modified based on public comments. The health basis for the pro- posed EPA standards is sup- ported by Federal agencies experienced in dealing with environmental carcinogens. The agencies include the National Cancer Institute, the National Institute of Environ- mental Health Sciences, and the Food and Drug Administration. The approach EPA is taking in the drinking water proposal has evolved as these and other health-oriented agencies have wrestled with the problems of regulating human exposure to carcinogens. Several important scientific conclusions about the nature of cancer have played a role in this evolution. First, there is the simple fact that exposure to chemicals can cause cancer. The first evidence of chemical carcinogenesis in humans dates back to 1 775, when Percival Pott noted that there were high rates of scrotal cancer in men who had been exposed to soot as chimney sweeps. During the 20th century, a number of in- dustrial chemicals, such as benzidine, asbestos, and vinyl chloride, have been shown to produce cancer in workers exposed to high levels, in addition, it is generally agreed that cigarette smoking and excessive exposure to sunlight can cause lung and skin cancer, respectively. Second, there is significant evidence that environmental rather than genetic factors are causing a significant amount of human cancer. A classic epi- demiological study was done of Japanese immigrants to the United States and their de- scendants. Japan has high rates of stomach cancer and low rates of colon cancer, com- pared to the U.S. When the Japanese immigrated to the U.S., their rates of stomach cancer fell and their rates of colon cancer increased. Among their children, the difference was even more marked: closer to the U.S. pattern and further from the Japanese pattern. Something about the U.S. diet, lifestyle, or environment produces lower rates of stom- ach cancer and higher rates of colon cancer than Japan. We don't know what these causa live factors are but we can presume that it is something in the en- vironment. (The term "environ- ment" here refers to everything humans are exposed to, includ- ing such things as cigarette smoking, food, and sunlight, as Victor J. Kimm is EPA's Deputy A ssistant A dministrator for Drinking Water. EPA JOURNAL ------- well as the results of environ- mental pollution in the usual sense.) Third, scientists have devel- oped methods for testing sus- pected carcinogens in labora- tory animals. This approach seemed necessary. Studies of cancer patients have been able to identify only a small number of human carcinogens. Also, our society doesn't allow inten- tional testing of humans with suspected carcinogens. So some method was needed to test the thousands of existing chemicals as well as the new ones that are constantly being developed. Although the differences between humans and rats and mice introduce uncertainty in the use of animal data, the test results have been well con- firmed: of the known human carcinogens, all but a few also cause tumors in laboratory ani- mals. These tests have been criticized for using doses much higher than those actually en- countered by people. The high doses are necessary to produce a response in enough of the animals so that conclusions can be reached without requir- ing thousands of animals to be tested. Additionally, the size of the dose is less important than its effect: if the result is cancer and not simply an over- burdening of the animals' sys- tems, there is reason for con- cern. In view of the conclusion discussed below that even very small doses of carcinogens carry some risk, the animal tests at high doses are valid for indicating the presence of a cancer risk and the relative potency of the chemical tested. In the case of organic con- taminants in drinking water, there is also a series of human epidemiological studies that have attempted to relate high human cancer rates to indica- tors of such contamination. This research has generally shown such a relationship. Such studies are difficult to interpret because other factors are also likely to be present in the large cities that have high levels of organics in their water. However, the fact that the re- search does show a relationship reinforces the concern about organic chemicals in drinking water, especially since some of the organics cause cancer in animal tests. Finally, and perhaps the most controversial, is the conclusion by the mainstream of scientific thought that there is no safe level for a carcinogen and that any exposure, no matter how small, will result in some risk of cancer. The reason for this con- clusion is that cancer seems to be the result of a small number of discrete events in the struc- ture of a single cell which trans- forms it into a cancer cell that can evade the body's defenses and grow in an uncontrolled way, ultimately producing death. We understand very little about how a chemical car- cinogen interacts with a cell's DNA to transform it, but it is believed that any case of chem- ical carcinogenesis is the result of a single molecule (or a small number of them) interacting with a single cell. It follows that exposure to a small amount of a carcinogen produces some small risk of cancer. The "no safe level" conclu- sion has important conse- quences. It means that expo- sures of large numbers of people even to very low levels of carcinogens are still a matter of concern, even if the risk to any particular individual ap- pears negligible. For example, if everyone in the U.S. had a one-in-100,000 chance of get- ting cancer as a result of such an exposure, certainly a very small risk, that would still mean 2,200 or so additional cases of cancer nationwide. It also means that the animal tests are valid bases for inferring human risk even with the very high doses which must be used in those tests for technical rea- sons. Although the environmen- tal exposures are usually orders of magnitude lower than those used in the animal tests, the number of people exposed is orders of magnitude higher. It should be noted that there are reputable scientists who do not accept the "no safe level" conclusion. However, in the disagreement, which isn't likely to be resolved in the foreseeable future, the preponderance of scientific opinion does accept it. So the regulatory agencies have found it prudent, as a matter of public policy, to take a conservative position and adopt the "no safe level" approach. Since exposure to any amount of a carcinogen carries some risk, regulatory decisions cannot be based on determina- tion of a safe level. But in many cases, complete elimination of the chemical from the environ- ment is not feasible or has costs that society would be unwilling to pay. EPA and other regula- tory agencies have therefore adopted the policy of mini- mizing any human exposure to carcinogens, provided the costs are reasonable. This is the ra- tionale that has guided the development of the proposed regulations to limit organic con- taminants in drinking water. EPA believes that the costs of the proposed regulations are quite reasonable. While a com- plete discussion of costs would exceed the space available here, the bottom line is that, in a city that would have to install granular activated carbon treat- ment, the average family's water bill would probably in- crease by about $10-520 per year. EPA's evaluation of the health risk has been endorsed by the Director of the National Cancer Institute, Dr. Arthur C. Upton. In a letter to EPA Admin- istrator Douglas M. Costle, Dr. Upton stated: "/ have reviewed the health basis of EPA's proposed regu- lations for control of organic contaminants in drinking water. ... Briefly, we support the judgement that these chemicals present a potential risk of can- cer that should be reduced to the extent feasible. A /though it is not possible at this time to quantify the actual hazard from exposure to chemi- cally contaminated drinking water or to determine the con- tribution to national cancer rates from drinking water, sev- eral conclusions can be drawn from the current thought on cancer cause and prevention: 1. Chemicals which have been shown to cause cancers in animal studies are com- monly found in drinking water in small amounts. 2. Some known human carci- nogens have been found in drinking water. 3. Exposure to even very small amounts of carcino- genic chemicals poses some risk and repeated exposure amplifies the risk. 4. Cancers induced by expo- sure to small amounts of chemicals may not be mani- fested for 20 or more years and thus are difficult to relate to a single specific cause. 5. Some portion of the popu- lation that is exposed is at a greater risk because of other contributing factors such as prior disease states, expo- sure to other chemicals, or genetic susceptibility. In addition, a number of epide- miological studies have been conducted which show a pat- tern of statistical association between elevated cancer risk rates and surrogates for organic contaminants in drinking water. While such studies are far from conclusive, when taken together with the toxicological data from animal testing, they constitute a further basis for public health concern. While we do not have [f/?e] ex- pertise to reach judgement on the feasibility of the treatment that would be required by the proposed regulations, we do believe that the potential risk justifies action and would en- courage you to reduce the amounts of chemicals in drink- ing water to the extent that is consistent with reasonably available means..." To summarize, we know that a great deal of human cancer is caused by unknown factors in the environment. We also know that certain chemicals that cause cancer in animals are found in low levels in air, food, and drinking water. These chemicals, and others that have not yet been tested, contribute to the total incidence of cancer, although the magnitude of the impact of each is unknown. Thus EPA believes that it should take the first step toward removing such chemicals from the Nation's drinking water. D SEPTEMBER 1978 27 ------- Ocean Dumping off New York By Peter W. Anderson Disposal of municipal sew- age sludge, industrial wastes, and dredged materials in ocean waters off New York is a regional issue of intense public interest and concern. The majority of these activities, past and present, in the U.S. occur at dump sites managed by Re- gion 2 in the New York Bight, an 11,000 square mile ocean area off the Eastern coastline extending from Cape May, N.J., to Montauk Point, N.Y. The honorary title of "Big Dumper" given to us by our friends stems from the fact that in 1977, for example, about 80 percent by volume of all dump- ing of sewage sludge, acid wastes, construction debris, and chemical wastes in the United States took place at four EPA-designated ocean dump sites in the Bight. When indus- trial dumping activities at a site off the north coast of Puerto Rico (also in Region 2) are in- cluded, this figure increases to 91 percent. This volume of municipal and industrial wastes being dumped in the Bight, and scientific evi- dence that the sewage sludge and dredged material are ad- versely impacting the marine environment, has resulted in "high public visibility," for the problem. Scientific investiga- tion, mainly by the National Oceanic and Atmospheric Ad- ministration, has documented several adverse environmental impacts at the sludge and dredged material sites. These include elevated con- centrations of heavy metals, organic matter, and bacteria in the water and bottom sediments with attendant threat of bio- Dr. Peter Anderson is chief of Region 2's Marine Protection Program accumulation in the food chain. Reduced catches of bony fish in high-carbon sediment areas also have been noted. Extensive areas have been closed to shell- fishing. Nutrient enrichment has resulted in increased phyto- plankton productivity. Fin rot, exoskeleton erosion, and gill clogging have occurred in cer- tain types of marine life—and sediments have been found in the vicinity of the dump sites devoid of normal bottom- dwelling marine life. Ocean dumping is by no means the only waste in the Bight. Pollutants from the Hudson-Raritan estuarine sys- tem, including raw sewage, inadequately treated municipal and industrial effluents, agricul- tural and urban runoff, com- bined storm-sewer discharges. and oil spills far outweigh ocean dumping in terms of total pollutant loading. Thus, it is difficult to ascribe these adverse impacts entirely to ocean dump- ing; however, it is a significant component in some instances. Most environmental inci- dents in the New York Bight are attributed to ocean dumping. For example, reports of sewage sludge (the popular "sludge monster") on the beaches of Long Island and New Jersey are common, although unsubstan- tiated, every spring and summer. The washup of "float- ables"—wood, plastic, tar- grease balls, paper, and similar debris—on Long Island beaches and an extensive kill of bottom- dwelling, fish and shellfish off the New Jersey coast in the summer of 1976 were attrib- uted to ocean dumping in most early press reports. However, subsequent evaluation of tech- nical information found that these two incidents were brought on by atypical atmos- pheric and hydrologic conditions aggravated by pollutants, pri- marily from inland sources. Ocean dumping was at most a minor contributing factor. Recognizing the magnitude of environmental problems in the Bight and its responsibili- ties under several Federal statutes, particularly the Marine Protection, Research, and Sanctuaries Act, Region 2 has carried out an ocean monitoring program involving several Federal, State, and local agen- cies. This is designed to collect and evaluate reliable environ- mental information, to support enforcement actions, and to determine the overall status of the marine environment. An effective program also was developed under the Region's permit program to require technically feasible, environ- mentally acceptable, and economically reasonable alter- natives to ocean dumping. Implementation of the Act in April 1973 spurred indus- trial ocean dumpers in the Region to construct land-based treatment facilities or to carry out other environmentally acceptable alternatives for handling their wastes. Of the roughly 150 industrial ocean dumpers in 1973, only eight remain. During 1977, these eight dumped almost 1.5 mil- lion wet tons of aqueous wastes. Typical wastes include water solutions of inorganic salts with trace amounts of organic compounds, liquid wastes from the manufacture of non-persis- tent organophosphate pesti- cides, acid wastes from the manufacture of titanium dioxide and fluorocarbons, and residual wastes from the manufacture of Pharmaceuticals. Five of the eight waste dumpers have agreed to stop ocean dumping on or before April, 1981. The remaining three have promised to bring their wastes into compliance with EPA's restrictive ocean dumping criteria by 1981 and to investigate innovative treat- ment technology. An addi- tional eight industrial waste sources in Puerto Rico are under firm compliance sched- ules to cease ocean dumping by 1981. Ocean dumping of municipal wastes has a less favorable record. It became clear shortly after passage of the Act that the construction of new and improved publicly-owned wastewater treatment facilities, scheduled for completion be- tween 1 977 and 1 983, would increase by 250 percent the amount of sludge generated by municipalities that practice ocean dumping in the Bight. In 1977, these sources dumped almost 4.5 million wet tons; by 1981, the time set by law to _stop the ocean dumping of harmful sewage sludge, these same sludge generators will be dumping an estimated 11.1 million wet tons. The problem of handling, in an environmentally acceptable manner, not only the present volume of sludge, but also the projected increases due to up- graded treatment, is only now being resolved. In 1974, in con- junction with the States of New Jersey and New York, the Re- gion funded a study by the Inter- state Sanitation Commission to determine feasible and environ- mentally acceptable alternative disposal methods for sewage sludge in a metropolitan area. In mid-1976, after evaluating the results of this study, the Region concluded that acceptable land- based alternatives such as com- posting, incineration, and pyrolysis were available. How- ever, it also was recognized that the major municipal dumpers in the metropolitan area could not implement an alternative dispo- sal method before the end of 1981, and even then only if no institutional or legal problems hindered implementation. Thus, since August 1976, all permits for the ocean dumping of sewage sludge have included a strict compliance schedule to cease ocean dumping on or be- fore December 31, 1981. (It should be noted that the Act was amended on November 4, 1977 to include this 1981 phase-out date for the disposal of sewage sludges, which un- reasonably degrade the marine environment.) These schedules include milestones for the pre- paration of facility plans and environmental assessments on the selected alternative(s), pub- lic hearings, preparation of plans end specifications, and initiation and completion of construction. All permittees are given the opportunity to comply with this permit condition using Con- struction Grant funds, and most have chosen this path. All of the alternate disposal options available to sludge dumpers have substantial en- vironmental impacts associated 28 EPAJOURNAL ------- with them. Metropolitan area sewage sludge contains ele- ments that are environmental problems in themselves, such as human pathogens (viruses, fungal spores, parasitic cysts, and bacteria), heavy metals (cadmium, rrjercury, chromium, etc.), and organohalogens (pesticides, PCB's, etc.). Aerobic composting, which is being considered by many sludge dumpers as an alterna- tive, is a beneficial use (recycl- ing) of the sludge. This process reduces the health risks from bacteria and viruses, reduces odor problems, and dilutes the metal and toxic organics con- tent. However, the risks from other pathogens (fungal spores, parasitic cysts) are not con- trolled, nor is the threat of bio- accumulation of heavy metals and toxic organics through the agricultural use of the com- posted material. Of additional concern are the potential envi- ronmental problems associated with percolation of nutrients, heavy metals, and toxic or- ganics into adjacent streams and groundwater aquifers. These concerns are particularly keen in Long Island and south- ern New Jersey, which depend on groundwater for potable water supplies. Thus, the use of composted sludges is being limited by State and Federal action to non-agricultural uses in accord with specific applica- tion rates. The other option actively be- ing considered is incineration. While pathogens and some toxic organics are destroyed, sewage sludge incineration re- sults in waste gases, particu- lates, and a sterile ash that re- tains most of the heavy metals originally present. The dis- charge of particulates, odors, volatile toxic organics, airborne metals (cadmium, mercury, and lead), and other waste gases could cause air pollution prob- lems. Facility plans developed by the 55 remaining sludge dump- ers, out of the roughly 250 plants in1 973, are be ing sub- mitted to the public for review. The decision point on which alternative disposal method to implement is at hand. It won't be an easy choice. D ''Current N.Y. Sludge Site -:N.Y. Acid Site A N.Y.

Waste Site SEPTEMBER 1978 29 ------- Around the Nation Environmental Town Meeting Set Region 1 and the Maine Audubon Society will co- sponsor an environmental town meeting in that State on October 12, William R. Adams, Jr., Regional Ad- ministrator and Henry War- ren, Commissioner of the Maine Department of En- vironmental Protection, will answer citizens' ques- tions about the impact of Federal and State environ- mental programs on Maine residents. Specific discus- sion topics will include environmental taws dealing with clean water and air, toxic substances, and solid waste. The town meeting wilt be heftt in the Main Lounge of the Moulton Union, Bowdoin College, Brunswick, Me. from 7:30 to 10 p.m. A similar meet- ing was held in Rhode Island earlier this year as part of a series being spon- sored by the Regional Office. Environmental Secretary Named Brendan J. Whittaker, a 44-year old forester and Episcopal priest, has been named Vermont's Secre- tary of Environmental Con- servation by Governor Richard A. Snelling. Whit- taker had been serving as the State's energy director, and was previously Direc tor of Information and Education for the State Agency for Environmental Conservation. Sole Source Designation EPA has designated the Long Island aquifer as the sole water supply source for Nassau and Suffolk Counties in New York State, in response to a peti- tion filed by the Environ- mental Defense Fund in January, 1975. Under the Safe Drinking Water Act of 1 974 any future project in the two counties that in- volves Federal assistance (through a grant, loan guar- antee, contract, or other- wise) will be subject to re- view by EPA for potential impact on the groundwater system. In making his deci- sion Administrator Douglas M. Costle noted that the aquifers are the principal source of drinking water for approximately 2.5 mil- lion people; that there is no economically feasible al- ternative to replace the groundwater system; that the system could become contaminated through its recharge zone, and that contamination of the aqui- fer would pose a significant public health problem. Eckardt C. Beck, Regional Administrator, called the designation "an important additional safeguard for protecting the health of Long Island residents." Beck added, "EPA will now carefully examine Fed- erally-assisted projects to ensure that the high water quality of Long Island's natural underground reser- voir is preserved." Water Pollution Jail Sentence Issued U.S. District Court Judge Edward R. Becker recently sentenced Manfred De- Rewal of Pennsylvania to a six-month jail sentence for dumping poisonous chemicals into the Dela- ware River in violation of the Federal Clean Water Act. DeRewal, who has owned or been associated with waste disposal com- panies in Pennsylvania, New Jersey and North Carolina, was also fined $20,000 and placed on four and one-half years probation. He has been cited for more than 100 State pollution violations over the past 1 3 years. Fol- lowing a detailed investiga- tion by the U.S. Attorney's office and Region 3's En- forcement Division, De- Rewal pleaded guilty to five counts of violating Federal pollution laws in March,1977. DeRewal and three accomplices had rented a warehouse near the Delaware River in Phil- adelphia where they stored over 730,000 gallons of waste solicited from vari- ous companies. The wastes were poured into a storm sewer through a manhole in the warehouse, and into the Delaware River near Philadelphia's Torresdale drinking water plant. Re- gional Administrator Jack J. Schramm said, "The sentencing serves notice on all persons involved in illegal dumping practices that the Federal Govern- ment will not tolerate any- one who risks the lives of others by illegally dis- charging dangerous chem- icals into our waterways." Pennsylvania Gets Permit Authority The Pennsylvania Depart- ment of Environmental Re- sources has been given the authority to administer the National Pollutant Dis- charge Elimination System permit program in that State. Pennsylvania is the fourth State in Region 3 to be given that authority and only the West Virginia pro- gram remains under Re- gional administration. Research Funding Set Through the Chesapeake Bay Program, Region 3 will be awarding approximately $9 million in Federal grants to State agencies, citizen groups, and research in- stitutions to study environ- mental problems of the Bay. Leaded Gas Violator Fined A Miami, Fla., service sta- tion operator has paid $8,300 in fines for putting leaded gasoline into ve- hicles marked "unleaded gasoline only." The com- pany, Alpine Enterprises, Inc., signed a consent agreement with Region 4 about the penalty. The firm had been observed intro- ducing leaded fuel into three cars. It also was charged with mislabeling dispensing pumps and fail- ing to equip pumps with the proper size nozzles. Forest Industries Comply Air pollution controls are being installed at three major forest industries in Region 4 before their facil- ities switch from burning oil to coal. The Westvaco Corporation in Charleston, S.C., expects to complete conversion by the end of 1979. Continental Forest Industries in Savannah, Ga., and Weyerhaeuser Company in Plymouth, N.C. should have com- pleted the change-over by mid-1981. Pollution from these coal-fired boilers, it is believed, will be less than present emissions from oil-fired units. There should be no delay in com- pliance with air pollution regulations because con trols will be installed be- fore the conversion is completed. Chemical Disposal Approved EPA has approved a chem- ical waste landfill near Livingston, Ala., for the disposal of polychlorinated biphenyls (PCB's), a chem- ical compound toxic to aquatic life and harmful to humans. The landfill, in east-central Alabama, is operated by Waste Man- agement, Inc. Agencies Cooperate Region 5 has reached an agreement with the Food and Drug Administration to have water samples ana- lyzed for pollution at the FDA laboratory in Minne- apolis, Minn. The innova- tive agreement was ar- ranged under a cooperative program announced last year by EPA, FDA, the Con- sumer Product Safety Commission, and the Oc- cupational Safety and Health Administration to share resources. Acting Regional Administrator Valdas V. Adamkus said the agreement will cut down on duplication of lab- oratory facilities by the two agencies for the Minneap- olis area. "Not only will this agreement increase our field monitoring capacity, but it is expected to save about $25,000," he added. 30 EPAJOURNAL ------- Cleaning A Lake EPA is funding half the cost of a $2.6 million project to clean up Lake Lansing, a 435-acre lake in Ingham County, Mich. Funds from the Agency's Clean Lakes Program are being matched by local sources. The proj- ect will attempt to restore the recreational potential of the lake through hy- draulic dredging, which will remove aquatic vege- tation and sediments that clog the lake. The project will be used to evaluate hydraulic dredging and determine the impact it would have on similar projects. PCB's Discovered in Sludge Scientists at EPA's Cen- tral Regional Laboratory in Chicago have found levels of polychlorinated bi- phenyls (PCB's) as high as 1 3 parts per million in samples of Nu-Earth, a fer- tilizer made from sludge processed by the Metro- politan Sanitary District of Greater Chicago. This level exceeds the recommended limit of 10 parts per million set by the Food and Drug Administration for the pro- tection of human health. Nine other chemicals clas- sified as polynuclear aro- matic hydrocarbons were also found in the sludge. Some polynuclear hydro- carbons are believed to cause cancer. Composted sludge has been distributed free of charge in the Chi- cago area by the Sanitary District for 5 years. set up at the Robert S. Kerr Environmental Research Laboratory in Ada, Okla. The wastewater treatment facility construction grant program, part of EPA's Office of Water and Waste Management, and the Agency's Office of Re- search and Development will combine their efforts to encourage and acceler- ate use of land application systems, in response to the 1977 amendments to the Clean Water Act and the policy on land treatment processes adopted by Ad- ministrator Douglas M. Costle. The Ada Lab has already been involved in research related to land treatment processes and protection of groundwater. Land application is espe- cially advantageous for smaller communities where land prices are compara- tively low and the costs of sophisticated treatment systems are prohibitive. enforcement activities, and stressed the Region's com- mitment to carrying out the regulations. State environ- mental agency staff mem- bers also participated in the meetings. In addition to the PCB regulations, the Regional Office employees discussed with the utilities the future regulation of coal ash disposal. Land Treatment Systems To Be Promoted With the encouragement of Regional Administrator Adlene Harrison, a coop- erative effort to stimulate use of land treatment sys- tems for cleaning up muni- cipal wastewater will be Utility Companies Briefed The Air and Hazardous Ma- terials Division recently held a series of one-day meetings with representa- tives of utility companies concerning the regulations for handling polychlori- nated biphenyls (PCB's) under the Resource Con- servation and Recovery Act. The regulations con- tain provisions covering recordkeeping, marking, and storage. The meetings, held in Lincoln, Neb., Jef- ferson City, Mo., and Bet- tendorf, Iowa, explained EPA's responsibilities un- der the new regulations as well. Morethan 135 people attended the meetings, where EPA staff set out inspection procedures and Noise Control Institute Set The region is cosponsoring the second annual Noise Control Institute with the Colorado Department of Health, the University of Colorado, the Community Noise Control Association, and the City of Boulder En- vironmental Protection Office. The institute, which will be held atthe Univer- sity of Colorado in Boulder, October 9-13, will be at- tended by noise control specialists from across the country. Sessions will cover all aspects important to the operation of a suc- cessful community noise . control program including training in the use of noise measurement tools, the physiological and psycho- logical effects of noise, and issuing summonses to noise violators. This year's institute will put special emphasis on land-use plan- ning for noise control, in- cluding information on criteria development; deal- ing with noise from traffic, airport/aircraft, railroads and industry; and review- ing plans for proposed development. Academic credit is available for peo- ple who attend the full five days. Special two- and three-day sessions also are available. A program bro- chure is available from the Bureau of Conferences and Institutes, 217 Academy, 970 Aurora Ave., Boulder, Colo. 80302, Attn.: Second Annual Noise Control Institute. Water Quality Management Planned The Pima County, Ariz., Association of Govern- ments' plan for areawide water quality management for the Mt. Lemmon area points out new solutions to eliminate discharges to a local creek. Sabino Creek is the only free-flowing stream in the area and is used heavily for recreation. Under the plan, prepared under section 208 of the Clean Water Act, the cen- tral collection and treat- ment systems in the area, which were functioning poorly, will be abandoned in favor of individual treat- ment systems, which will cost less and be more re- liable. All discharges into the creek will be eliminated under the current plan. Minority Contracting Improving Region 9 has awarded a contract to Homitz, Allen and Associates of Oakland, Cal. to improve participa- tion of minority architec- tural and engineering firms in the EPA construction grants program. The con- tractor acts as a "commu- nicator" with minority firms; informing them of available jobs, explaining regulations for contracting with EPA, and presenting seminars on organization skills. The contract has sig- nificantly increased minor- ity participation in Agency programs. Boat Noise Studied Last summer Region 10 helped the Washington State Department of Ecol- ogy gather information that will be used in the develop- ment of noise regulations for powerboats. EPA and the State noise personnel set up buoys just off the Seattle shore of Lake Washington and invited powerboat dealers and dis- tributors to run their boats through a course that al- lowed sound-level meas- urements to be taken off- shore. The regulations being developed are in- tended to reduce intrusive boat noise that bothers residents of beach houses, and other people on the shores of Washington's lakes, rivers, and marine waters. Disposal Sites Approved Region 10 has recently ap- proved two State-licensed waste disposal facilities. The facilities, located in Arlington, Ore., and Grand View, Idaho, may now accept discarded electrical equipment, soil, and other debris contaminated with polychlorinated biphenyis (PCB's). Both disposal sites are commercially operated. Each will be sub- ject to permits that contain eight pages of rigorous technical and operational requirements to ensure that the PCB's in the con- taminated waste never enter the surrounding environment. D SEPTEMBER 1978 31 ------- A major conference on the ur- ban environment has been scheduled for April, 1979, by three Federal agencies and several urban, labor and environmental groups. The goal is to gain a consensus on how to improve the quality of life in the Nation's depressed urban areas. "What we are trying to do is get a definition of 'urban envrronmentalism,' " said EPA's Deputy Administrator, Barbara Blum, in a press con- ference announcing the April plans. This is a "very new con- cept," she added, and if it is going to work, the definition for it has to come from the people who live in the cities, based on their priorites. Another conference aim, Blum said, is to forge "sort of an unholy alliance." It isn't unholy, but would have been thought so a few years ago, she explained. It would include "the people in the inner city, the environmentalists, the minorities, the labor unions." Such a coalition would "help us in our fight to preserve the inner cities." Blum predicted that the con- ference participants will in- clude ". . . housewife groups . . . butterfly groups . . . neighborhood groups . . . everyone who wants to par- ticipate in the city." The announcement of the conference was made jointly by Blum; Jay Janis, Undersec- retary of the Department of Housing and Urban Develop- ment (HUD); James Joseph, Undersecretary of the Depart- ment of the Interior (DOI), and by representatives of private co-sponsoring groups. They included Vernon Jordan of the National Urban League, Frank Wallick of the Urban Environ- ment Conference and Founda- tion, and Neil Goldstein of the Sierra Club. The fact that the three Federal agencies are helping fund the conference with a joint $11 5,000 grant is an acknowledgement that the Federal Government can't do the job alone, Blum said. "The keystone of the Administra- tion's urban policy is the forg- ing of a new partnership among the various levels of govern- ment, the private sector and Major Urban Conference Deputy Administrator Barbara Blum shared the announcement of an urban environmental conference with Vernon Jordan (loft), of the National Urban League and Jack Watson (right) Assistant to the !'ir>nt for Intergovernmental Affairs. the voluntary and neighborhood organizations," she said. "Urban environmentalism must become a key factor in this new partnership." The environment is impor- tant in the Administration's urban policy, Presidential Assistant Jack Watson added. "When we talk about urban policy, we are not just talking about roads and houses. We are not just talking about jobs. We are talking about the qual- ity of life in cities where peo- ple live. . . ." He called the participation of three Federal agencies in the urban environ- mental press conference "a harbinger of some very, very positive things to come." Wat- son is Assistant to the Presi- dent for Intergovernmental Affairs. Jordan, President of the National Urban League, ex- plained the common grounds for action in the urban environ- ment. "With the advancement of technology and the subse- quent urban sprawl, the urban areas have borne the brunt of air and water pollution, auto- dominated transportation, re- stricted housing opportunity and deteriorated neighbor- hoods." Now, he said, the damages. compounded by unemploy- ment and energy shortages, demand a common effort by environmental and urban re- form forces. The aim, he said, must be "a meaningful attack on the environmental problems that now plague the American cities." Jordan added that "there may be situations where blacks and whites violently disagree, but if the air isn't pure, it may not make any difference. That is one thing that is very diffi- cult to separate on the basis of race." In a speech to the Sierra Club last May, Blum also made a strong case for urban en- vironmentalism. "The flight to the suburbs is binding inner city and suburban people to- gether in ways that the sub- urban escapees did not antici- pate. The air, water, and noise may be most lethal downtown, but increasingly the metropoli- tan environment is one con- tinuous airshed, watershed and noise basin." "It's time to recognize that there is no place to hide," Blum added. "It's time for all urban residents, inner-city and suburban, to acknowledge that they share a common destiny. And it's time for the environ- mental movement to forge a new urban vision and make a sustained commitment to create a healthy urban environ- ment." The conference will be a key in shaping such a vision and launching a joint effort to achieve it. Conference objec- tives include identifying a national agenda to advance cooperation among labor, environmental and community groups, melding the socio- economic environment more closely with the physical en- vironment; identifying racial and economic factors camou- flaged as environmental mat- ters; and discussing technical subjects such as pollution con- trol, transportation, land use and drinking water quality. Goldstein, NationalConserva- tion Representative of the Sierra Club, supported the need for an urban environ- ment vision. "The Sierra Club," he said, "well known for its leadership in wilderness preservation, is determined to be a leading force for improv- ing America's cities as well." Goldstein said he believed his group could aid cities by "better focusing our urban environment efforts, forging coalitions with other organiza- tions, and calling upon a vast reservoir of volunteer talent. . . ." These steps needn't de- tract from "our current efforts in other areas. . . ." he added. EPAJOURNAL ------- Also supporting the vision of a better urban environment was HUD Undersecretary Jam's. "It is clear, for example, that quality housing requires qual- ity surroundings, such as clean air and water standards. It is clear that resources spent wisely for the environment are dollars spent wisely for housing. And it is also clear that dollars misspent for social programs are dollars misspent for the environment." Janis argued for "a sound balance between our environ- mental and urban needs in order to achieve the most good for the greatest number." Unde'rsecretary Joseph of the DOI said the urban environ- mental conference "can pro- vide a valuable springboard in bringing together these diverse groups and assist in the estab- lishment of a national grass roots network...." "There is an assumption in some places," he added, "that the concerns with ecology and equality are antithetical, that one movement focuses on eco- nomic justice, while the other is concerned not so much with power but with pollution. . . ." But Joseph believed that many who were raised in ghettos and barrios are now convinced that a clean environ- ment, "must go hand in hand with our other efforts to build a society which is healthy, humane and just." Wallick, Chair of the Board of the Urban Environment Con- ference, also saw a change in consciousness. "The environ- mental awareness of 1970— Earth Day—has given the whole country a feeling that we have to do something about the environment," he said. "And the environment is not restricted to the outdoor en- vironment. It is a part of our lives; it is a part of the work place." Wallick commended the Administration for its aid for the environmental conference scheduled for April. "I think the fact that the Administra- tion is willing to give us some sort of national visibility is very much a feather in their hat, and I hope we can make it successful." D Sharing Environmental Knowledge with Japan Continued from page 24 CEQ has responsibility for the 1 Hh project, which is en- titled, "Environmental Impact Assessments." At the Second Joint Planning and Coordina- tion Committee Meeting, the U.S. proposed that five new areas be added to the Agree- ment: water conservation and flow reduction, non-point source control and water quality management, measurement of by-product coke oven emission control technology, manage- ment and disposal of radioac- tive wastes, and environmental economics and incentives for pollution control. It is hoped that useful exchanges of infor- mation will soon begin in each of these areas. The participants in each of the eleven established projects meet on a regular basis. The sessions are held in Japan one year and in the United States the next. It is from these tech- nical meetings that the real fruits of this cooperation are realized, for they provide each country with first-hand informa- tion on how each nation deals with common environmental problems. Visits to field facili- ties are also arranged during the sessions to provide partici- pants with an opportunity to see technical innovations and mod- ifications in pollution control equipment. For example, a team representing EPA's Kepone Mitigation Feasibility Task Force, the Management of Bot- tom Sediments Containing Toxic Pollutants project, and members of the U.S. Army Corps of Engineers recently returned from a visit to Japan where they met with representa- tives of several industrial firms. This EPA-sponsored team observed newly-developed dredging technology and ad- vanced techniques for handling contaminated sediments and sludges. From this visit and further discussions, it is highly probable that this Japanese technology will be useful in aiding the United States in handling its in-place toxic pol- lutant problems and refining its technology. To date, the Japanese technology has been used effectively on sludge and sediments contaminated by mercury, copper, zinc, cad- mium, lead, chromium and PCB's. Subsequent investiga- tions are underway to deter- mine whether this technology can aid in any future clean-up of Kepone in the James River, Virginia. The two countries have also worked together in the area of radioactive waste disposal. For example, this past June Japan sent a scientist to participate in EPA's low-level radioactive waste recovery dive program. This team surveyed and con- ducted tests in a radioactive waste dump site located approx- imately 200 miles off the Maryland/Delaware coast. The Japanese participant from Japan's Atomic Energy and Re- search Institute not only took part in the analysis and survey segment of the program but also participated in several of the scheduled dives. Sharing Expertise Still another benefit derived from our bilateral cooperation is the exchange of technical experts. Over a dozen qualified Japanese research scientists have visited our laboratories and facilities. These scientists have stayed in the United States for as long as one year, and have performed valuable work for EPA and for their own na- tional programs. Individual areas of study are agreed upon prior to their arrival. Detailed reports are written for both nations once the assignments have been completed. Over the years, Japanese scientists have visited our laboratories in North Carolina, Ohio, New Jersey, Oregon, and Nevada. The bene- fits derived from this exchange program come not only in the completion of the agreed upon scope of work, but also in the development of lasting profes- sional and personal relationships. While EPA does not send researchers to Japan for such extended periods, we do send fact-finding teams to gain valu- able information on a variety of industrial pollution control topics. Teams have visited Japan recently to gain informa- tion in the areas of flue gas de- sulfurization and noise pollu- tion control. A team is tenta- tively scheduled to conduct a survey of Japan's pollution control practices in the iron and steel industry. Several officials from Japan's Environment Agency have visited EPA's headquarters to become familiar with our na- tional policies and to observe how environmental matters are handled at the national level. In addition, EPA receives approx- imately 2,000 Japanese visi- tors each year. Their interests range from such topics as the preparation of environmental impact statements to the role public interest groups play in setting national environmental policy. These are some of the num- erous ways in which Japan and the United States have been cooperating in the environ- mental area in recent years. The basic culture of the Jap- anese lays great stress on har- mony between man and nature, and we have much to learn from this philosophy. In sim- ilar fashion, as Japan has moved into a world role as a highly industrialized country. she has profited by studying our legislation and technology in the field of pollution control and abatement. The U. S.- Japan Agreement augurs well for a continuation of the use- ful exchange of environmental information between the two nations. D SEPTEMBER 1978 33 ------- Congress Expedites Pesticide Program ^ Both EPA and farmers "should be particularly optimistic about the future of our pesticide program" as a result of recent amendments to the Federal Pesticide law, Steven D. Jellinek, Assistant Administrator for Toxic Sub- stances, has declared. A House and Senate Confer- ence Committee at press time had approved a number of amendments to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Jellinek, in an address to the Southern Commodity Producers Conference in Birmingham, Alabama July 27, said there were several aspects to the amendments that merited attention: • Conditional registration per- mitting EPA to register products similar to old chemicals or providing new uses of them; • A "generic standards" ap- proach allowing EPA to make broad decisions for an entire group of products containing the same ingredient; • A diminished requirement for reviews on the efficacy of pesticides; • A liberalized approach to uses of a pesticide that are not in literal accord with the printed label on the product. Jellinek, who spoke at the invitation of the Alabama Farm Bureau Federation, said that the "conditional registration" amendment "will greatly im- prove our ability to register products that are similar to or are actually new uses of old chemicals." He said it was "very frustrating" to have to turn down numerous applica- tions because of a double stand- ard that allows continued use of products already registered but requires a full complement of registration data before iden- tical new products can be reg- istered. Jellinek added that EPA planned to issue regula- tions ior conditional registra- tion within the new few months, and begin issuing such registra- tions immediately thereafter. The generic standards ap- proach to re-registration of existing pesticides will make possible a more streamlined procedure rather than the pre- sent practice of regulatory deci- sions on a product-by-product basis. With respect to efficacy re- views, Jellinek explained that under the amendments EPA will depend more and more on farm- ers for information on how pes- ticides are actually performing under field conditions. "We will look to the Department of Agri- culture and the land-grant uni- versity system for feedback on efficacy," he declared, "rather than relying on data from the registrants that becomes rapid- ly outdated owing to regional and climatic variations and changing degrees of pest resistance." On the final point, the Assist- ant Administrator said the amendments provide a new definition of "use inconsistent with the label." It makes clear that certain practices, which may not be in strict or literal accord with the printed label, are nonetheless legally con- sistent with label directions. "Specifically," he said, "farmers and other pesticide applicators will be able to use less than the specified label dosage, to treat for a pest not listed on the label, to mix pesti- cides and fertilizers, and to employ responsible methods of application not specified on the label. "We expect that these changes will introduce a wel- come measure of common sense to pesticide use enforce- ment, which incidentally under the new legislation will become even more of a State respon- sibility than it is now." The agreement by House- Senate conferees on the FIFRA amendments was reached in July after eight months of nego- tiations. Still awaiting action at press time was approval by the full House and Senate and the President's signature before the amendments could become law. Jellinek told the Commodity Producers Conference that a fundamental dilemma is re- flected in FIFRA: "First, pesticides are among the riskiest chemicals used in our society. "And second, pesticides are necessary for modern agricul- tural productivity and progress." In essence, he said, the Fed- eral pesticide law "requires EPA to balance the risks of pes- ticides exposure to humans and the environment against the benefits of pesticide use to society and the economy. On one hand, we must protect society from the risks of using pesticides. On the other we must assure that American agri- culture has, and wil! continue to have, the necessary pest-control tools to meet the Nation's— and to an ever-increasing ex- tent, the world's—needs for food and fiber. "I assure you that this task is neither simple nor easy. The pressures that prevail upon us are enormous," he added. Pesticide use has been in- creasing rapidly since the mid- 1 960's. Jellinek pointed out that about 35,000 pesticides are now registered for use in the United States. The U.S. market for pesticides in 1976 was $2.4 billion and by 1984 is expected to grow to $3.3 billion. Produc- tion of pesticides in the United States grew from one billion pounds in 1966 to 1.4 billion in 1976, with more than half the total used by agriculture. The figures indicate that the in- crease is likely to continue, he said, along with chance of wide- spread human and environmen- tal exposure to dangerous chemical pesticides. At the same time, agriculture is a more highly competitive endeavor than ever before, he declared, with farmers expected to produce more food and fiber at lower prices to the consumer while maintaining profit levels that enable their businesses to survive. "That isn't easy, either, and we know it," Jellinek said. He cited a number of recent decisions by EPA on various pesticides to illustrate that "we have not—as some of our cri- tics have charged—stuck to a predetermined, knee-jerk pat- tern of decision-making that favors any particular constituency." The Assistant Administrator conceded that the Office of Pes- ticide Programs has a number of deficiencies to overcome and is working hard to do so. "And we need to do a better job of con- veying the message," he said, "that we are neither weak- kneed apologists for the pesti- cide industry nor rampant cru- saders against the use of every pesticide on the market today —because we are not." In summarizing the complex decisions on certain pesticides in recent times, he emphasized that in each case the science was examined, costs and bene- fits carefully and objectively evaluated, alternatives ex- plored, and as fair a decision as possible was rendered. Modern agriculture, he con- cluded, "is one of America's most promising economic ad- vantages in a time when our country needs economic advan- tages perhaps more than ever before. I am convinced that we can continue to strengthen this advantage while at the same time prevent the adverse human health and environmental im- pacts that sometimes accom- pany agricultural progress."

In addition to Agency officials, participants will include Mem- bers of Congress, representa- tives of State agencies, profes- sional design societies, and industry. Q An Environmental Calamity: The Seveso Case Continued from page 15 plete. It is evident that a power- ful impulse exists to put a good face on the matter, concentrate on the final decision to fence off the zone that simply cannot be handled in any other way, and dampen down public con- cern over any other sequels to the disaster. A particular effort was made to get people out of the Resi- dencia Leonardo da Vinci and back in their homes, as the evacuation was certainly the most traumatic and conspicuous social consequence of the ac- cident. Of 140 families evac- uated, 1 20 have now been returned to their homes. Their houses were decontaminated by removing the tile roofs, vacuuming and scrubbing the walls with detergent and solvent and clearing the grounds around them. New roofs, ap- pliances, and furnishings have been provided. Only limited use can be made of the land around them. The area still looks desolate. But the houses were treasured as many of the owners built them with their own labor. In the fall of 1977, the re- maining problems and the long- term management of the con- taminated area were turned over from the Lombardy Re- gion to a new commission - which has established offices in the Augustinian Seminary in Seveso. Its tasks will be to supervise medical monitoring, continuing land decontamina- tion studies and work, and maintenance of vigilance over the closed area. Eventually they will have to deal with the dis- posal of all of the contaminated waste. The ICMESA factory will have to be demolished. Its rubble will be added to the other TCDD-contaminated ma- terial which is held within the closed zone. This consists of mounds of plastic bags filled with the vegetation collected from the whole contaminated area; thousands of items of protective clothing, coveralls (changed daily), gloves, masks, head coverings, boots, worn by the cleanup squads, to which more is being added as any work goes on; plus the roof tiles and the furnishings taken from the vacated houses; together with the carcasses of 35,000 animals that died or were slaughtered, preserved in metal containers stacked up row on row; and also the trucks, tools and other equipment contaminated by use in the poisoned area. The costs of all this has amounted to billions of lire already, with a great deal more still to be required, by some means, from public funds. T' The Hoffman-La Roche Company faces damages of up to $50 million for the contamination of Seveso, according to a company official. Adolf Jann, chairman of the Swiss chemical company, told a news conference recently that La Roche had bought properties in the worst- hit areas from the former inhabitants, and all other families had now been allowed to return. Jann said a final decision on the company's liabilities was expected soon, but he did not expect total damages to exceed $50 million. He added that three boys from Seveso were still suffering from a serious form of acne SEPTEMBER 1978 35 ------- Environ- mental Response Team Environmental response tnam mnmhnr wears a • r.h<;mical protective garment while trying to close off a leaking tank truck during a simulated environmental disaster. The television news may one evening picture a figure clothed in protective suit with self-contained air supply entering a sewer or approaching a tank car. This is not an astronaut or the man from SWAT. It's some- one from EPA, a member of a new group set up to improve the Agency's ability to cope with environmental emergencies. The Environmental Response Team will have a core staff of six with new skills required by provisions of the Clean Water Act. Now that the initial list of hazardous substances has been issued under the Act, EPA will have new responsibilities for protecting public health and the environment from chemical spills into waterways. But the team's charge will be more comprehensive than just responding to spills. It encom- passes, for example, averting contamination of public water supplies, aiding in the disposal of solid and hazardous wastes. Federal disaster assistance, and preventing the release of toxic air pollutants. The team will permit EPA to provide around-the-clock support to the Regional offices with personnel whose sole responsibility is to respond to environmental emergencies. Establishment of the Re- sponse Team comes at a time when EPA is becoming increas- ingly concerned with environ- mental emergencies. The des- ignation of hazardous sub- stances under the Clean Water Act, the task set by the Toxic Substances Control Act, and the emphasis on hazardous wastes in the Resource Con- servation and Recovery Act all signal greater responsibilities in the area of environmental emergencies. Reflecting this new concern, EPA Administrator Douglas M. Costle in October 1977 re- quested the Office of Planning and Management to study the Agency's capabilities in pre- venting and responding to environmental emergencies. Paul Elston, Deputy Assistant Administrator for Resource Management, set up an emer- gency response task force to analyze the Agency's activities. In December the work of the task force expanded when the Interagency Toxic Substances Strategy Committee was estab- lished and EPA was designated the lead agency for developing an interagency plan to deal with chemical crises. Staffing of the Response Team is just getting underway. All are likely to be already em- ployed by EPA as emergency response experts or other spe- cialists. The membership will probably include chemists, toxi- cologists, biologists, sanitary engineers, and a specialist in waste disposal techniques such as incineration and landfilling. Since the work will be physi- cally demanding and require considerable travel, team mem- bers will be subjected to rigor- ous physical examinations before they are selected and will have periodic examinations to ensure that they have not been affected by exposure to low levels of toxic chemicals. When not responding to envi- ronmental emergencies, they will conduct training sessions for EPA and State employees, developing contingency plans, and prepare operating manuals and other technical documents. To ensure that the regula- tions for responding to chemical crises are appropriate and fea- sible, the Emergency Response Task Force held a meeting re- cently at EPA Headquarters in Washington, D.C. to consider suggestions from various or- ganizations. The meeting was chaired by Office of Public Awareness Director Joan Mar- tin Nicholson and included rep- resentatives from trade asso- ciations, labor organizations, chemical firms, and environ- mental groups. They stressed the need for cooperation, coor- dination, and public informa- tion both before and after an emergency situation occurs. According to Kenneth Big- lane, Director of the Oil and Special Materials Control Divi- sion, the team will function as a special unit in his Division. Although its location has not been selected, it is likely to be started in the heavily indus- trialized areas of the eastern United States. In general, re- quests for the team will come from the Regional Administra- tor's Emergency Coordinator once he has concluded that the Region needs assistance. The team will be particularly valu- able when more than one Re- gion is involved. An incident on the Ohio River, for example, could involve Regions 3, 4, and 5. On the scene, the Emer- gency Response Team will be more than a "Band-Aid" opera- tion, according to Ken Biglane. Taking as an example a chem- ical spill into a stream on a Friday evening, Biglane says. "The Response Team will pro- EPAJOURNAL ------- vide immediate assistance to the Regional On-Scene Coordi- nator monitoring the chemicals, predicting when they will pass, providing emergency water treatment technology or arrang- ing to have water trucked in. The team will come up with solutions, techniques, and measures to minimize the im- mediate threat, giving other EPA program offices time to marshal their resources." The Emergency Response Team concept has its origin in Section 311 of the 1972 Water Act, which called for prepara- tion of a National Contingency Plan to handle spills of oil and hazardous substances when the spiller is not taking proper cleanup actions. The plan, published in 1973 by the Council on Environmen- tal Quality, coordinates Federal cleanup efforts. Responsibility for on-scene coordination rests with EPA for spills into inland waters, while the Coast Guard in the Department of Transpor- tation is responsible for spills in coastal waters and the Great Lakes. EPA draws its on-scene coor- dinators from the 56 emergency response specialists in the Re- gional Offices. They are trained in disciplines such as biology, chemistry, engineering, and oceanography and are experi- enced in cleaning up and re- moving spills or mitigating their environmental effects. They also view and inspect the spill control and countermeas- ure plans that facilities handling oil and hazardous materials must prepare. EPA is involved in about 3,000 spills a year, but only 50 require an on-scene coordinator to take over the cleanup operation. EPA's emergency response has not been confined to oil spills, however. Although the list of hazardous substances was not designated until March 1978, EPA responded to such spills in the interest of public welfare. For example, EPA pro- vided an on-scene coordinator in October 1973 when 1 5 rail- road cars derailed near Rush, Ky., spilling acrylonitrile into a nearby creek, and in Septem- ber 1974 when 260 gallons of PCB's were spilled in the Duwamish Waterway in Washington State. The Response Team will also provide EPA with new skills in situations like that at the Ken- tucky acrylonitrile case, where the choice had to be made between permitting the spilled acrylonitrile to continue to burn or to try to put the fire out. Local officials decided to ex- tinguish the fire although they were uncertain about the air pollutants resulting from open burning. One member of the team will be an expert in this area, al- though predicting combustion products under the highly vari- able conditions of open burning is tremendously complicated. The Response Team is likely to be less hardware-oriented than the Coast Guard's strike forces, although it will have some special mobile equipment. The team will be responsible for running the Environmental Emergency Response Unit, now operated by the Industrial En- vironmental Research Labora- tory in Edison, N.J. The unit is a trailer mainly intended to re- move chemicals by carbon ad- sorption, but it uses a series of physical and chemical proc- esses in a versatile system suit- able for on-site removal and treatment of both chemicals and oil. The team will also have compact laboratory and moni- toring equipment that can be transported to the scene of an emergency. Other special mo- bile equipment will be added to the Response Team's arsenal in the future. Among them are a special mobile incinerator now being designed by the Office of Research and Development and the Dynactor, a reaction cham- ber in which chemicals are diffused into small particles so that they can be treated very quickly. Eventually, Biglane plans to have teams in Edison, Cincin- nati, and on the West Coast. With these teams, Biglane says, "We hope to bolster State and local programs for disaster as- sistance. After all, the local communities are the ones on the receiving end of all environ- mental catastrophies. They need help. These teams are programmed to provide that help through EPA's Regional Offices." D Wanted: More Toxicologists Continued from page 22 tions of scientists in health- related areas. These societies should also consider scholar- ship programs, prizes, awards, and other activities that might increase awareness of toxicol- ogy as a profession, conferees declared. The Role of Institutions "The absence of a Federal Civil Service job category entitled 'toxicologist' is a severe imped- iment to effective recruitment of outstanding toxicologists into the regulatory agencies, since the entire existing Federal ap- paratus for advertising and hir- ing, as welt as for career ad- vancement, is based on the existence of a carefully defined Civil Service professional lad- der," the report noted. Without this job category, if a Federal agency needs to hire a toxicolo- gist it must fill a job category called "biologist" or "pharma- cologist/toxicologist," and the qualifications most central to toxicology cannot be taken into account and rewarded ade- quately. For example, if a GS-13 biochemist acquires additional skills in toxicology, there may not be a job category into which he or she can be promoted that recognizes them. Yet it is this kind of retraining that is badly needed to meet the demand for toxicologists, the report noted. "We strongly recommend that the Civil Service establish a career category and promo- tional ladder for 'toxicologist,' " the report said. "Toxicology is a profession; the establishment of a career ladder will aid the Federal Government in the re- cruitment and retention of qual- ified professionals. The Society of Toxicology, we believe, should address this issue, as should the officials in the Fed- eral Government whose depart- ments and agencies must recruit and retain highly qualified toxicologists." Industry The report added that there are many opportunities for industry to recruit trainees in toxicology. Some companies have pro- grams for training technicians and junior scientists, and these programs could be expanded, perhaps in cooperation with local universities. Industry also might explore cooperative pro- grams with universities, such as joint staff appointments which would involve the appointee more fully in the industry and the university. Industry is routinely asked to expand its support of university programs in toxicology, and some have argued that industry has a principal responsibility for this training, since chem- icals are manufactured and marketed by industry, and roughly one-third of the pool of trained toxicologists finti em- ployment in industry, according to conferees. The consensus was that industry can and should contribute to training toxicologists at universities. They noted the training of toxi- cologists at universities is in large measure a public responsibility. "At the same time, the rate of development of industrial research centers is staggering," the report declared. It is esti- mated there was a 70 to 100 percent increase in industrial toxicology facilities from 1975 to 1977, and that there will be a further 100 percent increase during the next few years. "There are not enough well- trained people to go around, and the hiring of toxicologists from one institution to another has already reached 'robbing Peter to pay Paul' proportions," the report stated. "Clearly, in- dustry has a major stake in expanding the supply of trained professionals just to meet its own needs. Greater financial support of toxicology training programs by corporations would both serve the national interest and contribute to meet- ing the need for toxicologists which many industrial toxico- logy laboratories already feel acutely."

SEPTEMBER 1978 37 ------- EPA Studies Birth Mishaps In Oregon Town News Briefs EPA is probing the cause of 10 miscarriages between 1973 and 1977 among eight women in a small Oregon town to determine if the mishaps were caused by herbicide spraying in nearby forests. "We're uncertain at this point whether herbicides are responsible for the miscarriages," said EPA Administrator Douglas M. Costle recently. "But one of the herbicides in question, namely 2,4,5-?, has caused birth defects and stillbirths among laboratory animals such as mice, rats, hamsters and birds. Another of the brush killers, Silvex, is being studied by EPA for the same reasons." Also, Costle added, the Oregon women have stated that the times of their miscarriages correlate closely with the times of herbicide treatments in the forests. Blum Testifies On Inflation EPA Tightens Limit For Fuel Evaporation "EPA's regulations are not a major contributor to inflation, although we acknowledge our responsibility to seek least-cost approaches to reaching environmental goals," EPA Deputy Administrator Barbara Blum recently told a House Subcommittee. Although EPA's regulatory actions have an impact on the Consumer Price Index (CPI), Blum said, "any conceivable modification of current regulations would not substantially alter the nation's underlying inflation rate." Environmental cleanup results in a number of positive and anti-inflationary effects such as fewer illnesses, fewer lost work days, and lower medical bills, Blum told the Subcommittee on Economic Stability of the Committee on Banking, Finance and Urban Affairs. EPA Administrator Douglas M. Costle recently announced a tougher standard for the reduction of evaporative emissions for gas-fueled cars and light trucks, starting with the 1981 model year. The new standard will reduce nationwide hydrocarbon emissions from all mobile sources by as much as 10 percent in 1985, and 25 percent by 1990. It will replace the standard which began with the 1978 models. Evaporative emissions are the hydrocarbon molecules in gasoline vapors that escape from cars and trucks in addition to emissions in the exhaust.

Tennant Award from Federally Employed Women (FEW), an organization dedicated to win- ning equal opportunity for working women. Reiter won the award for her efforts in han- dling the International Women's Year National Conference in Houston, Tex. She was respon- sible for registering over 23,000 participants at the Con- ference. She also won the EPA Bronze Medal for excellence in the Federal Women's Program in June, 1977. Joseph Padgett The Director of the Strategies and Air Standards Division at Research Triangle Park, N.C. was recently elected to a 3-year term on the Air Pollution Con- trol Association's Board of Directors. Padgett began his professional career in 1948 with Westinghouse Corporation as a design engineer. Since then he has worked for a num- ber of private companies in various engineering and mana- gerial positions, including the USI Technical Center, Parsons Corporation, and the Atlantic Richfield Corporation until 1 970, when he began working for the United States Postal Service. In 1971 he joined EPA as Chief of the Systems Anal- ysis Staff in the Office of Air Programs and assumed his present Directorship in 1972. Padgett received his B.E. De- gree in Mechanical Engineering from the Johns Hopkins Univer- sity in 1948 and an M.S. in the same field from the California Institute of Technology in 1951. He is a registered Pro- fessional Engineer in the State of Ohio and holds several patents. Lam K. Lim He has been cited by President Carter for initiating and imple- menting the EPA Value Engi- neering Program as part of the Construction Grants regulations at a savings to the government of S75 million. Lim is a sani- tary engineer with the Muni- cipal Technology Branch, Muni- cipal Construction Division. He heads an independent team of design engineers who review proposed construction projects for unnecessarily high costs and suggest cheaper alternative methods of completing the project. Although voluntary at first, Value Engineering analysis is now required of all projects costing $10 million or more which seek grants. Lim also received the EPA Bronze Medal for his services in June 1977. James A. Chamblee He has been cited by President Carter for outstanding accom- plishments as Chief of the Pri- orities and Needs Assessment Section, Water and Waste Man- agement Program. In a recent letter the President specifically thanked him for his money- saving efforts in reducing gov- ernment forms. Chamblee, who is responsible for conducting the 'State Facility Needs Sur- vey', redesigned the Survey questionnaire from its old 37- page length down to just one page, saving the government an estimated $1.2 million in re- lated processing costs. He also was cited by Administrator Douglas M. Costle for his ac- complishments in carrying out the Survey itself. He was pre- viously awarded the EPA Bronze Medal in June 1977, and in December of that year received a $2,300 cash award as a Special Achievement Award for Special Service. Sarah T. Kadec She has been appointed Assist- ant Director for Information Services at the Executive Office of the President, reporting to Richard Harden, Director of Administration. Mrs. Kadec has served as Chief of the Library Services Branch at EPA Headquarters since May, 1971. In 1975 she was awarded the EPA Silver Medal for Superior Service. The previous year she received a commendation from the Admin- istrator for helping to establish the Federal Energy Administra- tion's National Energy Informa- tion Center. Mrs. Kadec received an A.B. degree in 1952 from Madison College and a Master's degree in library science in 1961 from the Carnegie Institute of Tech- nology. She has been involved in library and information systems work for a number of Washing- ton-area industries and agen- cies and taught at the Univer- sity of Maryland and Catholic University library schools. In 1969-70 she served as a con- sultant to the Center for Scien- tific and Technological Informa- tion in Tel-Aviv. SEPTEMBER 1978 39 ------- Report The Rocky Mountain Region By Alan Merson Regional Administrator Every Region contains, in some measure, what Region 8 epito- mizes: areas of clean air, clean water and land largely un- spoiled by man. While EPA's foremost priority must, of course, be protection of the public health. Region 8 must necessarily interpret that goal in the context of a prevention strategy. The factor driving that strat- egy more than any other is the rapid economic growth over- taking the six States of Region 8, but largely concentrated in the energy-rich inter-mountain region, where a majority of the Nation's energy resources for the next hundred years will probably be found. The clash between Region 8's still rela- tively undeveloped land mass and the rapidly accelerating pace of energy development is producing, in some areas, a dramatic discord which can only reach a crescendo in com- ing years. Virtually every major issue confronted by our Regional Office is an outgrowth of this clash. Exploding population growth in Denver, Salt Lake City, Billings, Casper, and Grand Junction all represent variations of this theme in addi- tion to the smaller, more obvi- ous, energy boom towns, such as Craig, Colorado, and Rock Springs and Gillette, Wyoming. It seems appropriate, there- fore, to depart from the format of previous Regional Office narratives in order to illustrate in anecdotal fashion the work- ing out of this theme. This is not to say that Region 8 ne- glects EPA's more traditional environmental clean-up func- tions. Our Enforcement Divi- sion, for example, recently secured a settlement with a major steel mill in Colorado, which will result in probably the cleanest coke oven emissions in the Nation. We maintain an active permit enforcement pro- gram against major polluters of the numerous streams rising within our region, although it is mo re likely to be concerned with mining than manufacturing activities. We have active solid waste, radiation and noise programs which, al- though short on resources, have been long on innova- tion and creativity. We have had an extensive involve- ment in pesticides, and are currently admin- istering one of the few EPA-run pesticide certification programs in the Nation. We have a special concern with toxic substances in the Denver area. Still and all. Region 8 remains basically clean. How to keep it clean is our greatest challenge. Let us examine four cases, be- gining with the City of Denver itself. Once famous for pristine air, Denver has witnessed a grad- ual worsening of air quality over the past decade until it now ranks as the second dirti- est metropolitan area in the Nation. For many years, efforts to improve Denver's air quality met with little interest or com- mitment on the part of the pub- lic. Last fall and earlier this year, however, Denverites ex- perienced a growing number of increasingly serious air pollution alerts. Public opinion surveys indicated that air quality was the single most disturbing issue to residents of the Denver area. Last November the Regional Office detailed 1 5 of our em- ployees to a Denver Air Task Force to work exclusively on Denver's air crisis, first to mo- bilize the 43,000 Federal em- ployees of the Denver area to end their reliance on single occupancy vehicles, and, sec- ond, as Federal efforts in such example-setting became visible, to assist the private sector in doing likewise. This strategy, developed with State and local officials and with our sister Federal agencies, was commended by President Carter during his visit to Denver on Sun Day last May. The President pledged his personal support for Den- ver's clean air campaign and asked that EPA and the Federal Regional Counsel coordinate an aggressive Federal effort to support local initiatives. The President catalogued some $42 million that will ultimately be made available for the Denver air project, including money for transit-related construction, free off-peak hours bus service, electric car demonstrations, an inspection and maintenance awareness campaign, meas- ures to prevent tampering with emission controls, and a direc- tive to our Regional Office to report to him on a monthly basis on the progress of this initiative. Another regional issue of major importance is closely linked with the Denver air qual- ity picture and is an excellent example of the interrelation- ship between air, water, and land use. The Foothills Project is a proposed water treatment plant, dam, reservoir, and tun- nel system designed to nearly double the Denver Water De- partment's treatment capacity. Since some public lands are involved in the project area, an environmental impact state- ment (EIS) was prepared. It fell to this regional office to review that statement under the Na tional Environmental Policy Act and section 309 of the Clean Air Act. After extensive review, Re- gion 8 concluded that the im- pacts of the project were sub- stantial and that alternatives to the project had not been ade- quately considered. On that basis, we referred the matter to the President's Council on Environmental Quality. CEO agreed with our assessment and recommended that right of way permits be denied by the Federal agencies managing the lands in the project area. The permits were nevertheless issued. EPAJOURNAL ------- Region 8 was then asked to advise the Army Corps of Engi- neers as to the propriety of granting a dredge and fill per- mit for the proposed dam under Section 404 of the Clean Water Act. The Region conducted two lengthy public hearings pri- marily to determine whether in fact less environmentally dam- aging alternatives to the pro- posed dam had been adequately investigated. Concluding that they had not, the Region recom- mended against issuance of the permit, leaving it now for the Corps to decide that issue. In response to considerable Con- gressional interest, the Corps has agreed to undertake an exhaustive analysis of alterna- tives before rendering its deci- sion. This in itself goes a long way toward meeting the Re- gion's concerns. Whatever the outcome, the link is established. Water avail- ability helps shape growth pat- terns which in turn largely determine the quality of air in the region. That same link exists in wastewater treatment, a fact which has led us to the prepara- tion of an "overview" environ- mental impact statement to examine the cumulative im- pacts of funding ten waste- water treatment projects in the Denver metro area. Funding of additional waste- water treatment capacity sup- ports growth. Growth without commensurate air quality con- trols will result in continued air pollution problems in the Den- ver region. In the framework of the EIS and of the 208 planning process, we developed policies which will guide our future funding of treatment works, including: The philosophy behind the overview EIS assumes that Federal expenditures in many of our urban areas shape growth. Here, as in 208 and State Implementation Plan revisions, Region 8 is working to insure that Federal managers carefully evaluate the impacts of these expenditures as they affect environmental quality and to do so in cooperation with other agencies whose pro- grams may cross-cut one another. Yet another example of the responsibility placed upon our Region to perform its function of safeguarding environmental quality in areas of rapid devel- opment is the coal-fired power plants at Colstrip, Montana. Two plants there now generate some 700 megawatts of elec- tricity. Construction of two additional units which would each generate an additional 700 megawatts has been proposed. Approximately twenty miles from Colstrip lies the Northern Cheyenne Indian Reservation, an area of Class I air quality under the Prevention of Sig- nificant Deterioration policy. Montana Power Company, rep- resenting a consortium of utilities, app ltd In pre-con- struction pern-it^ under this policy, which is, ot course, de- signed to protect the quality of air already cleaner than that required by the National Am- bient Air Quality Standards. Extensive analysis of data generated by computer mocfei- ing and actual meteorological data led us to conclude that Colstrip Units 3 and 4, if built as planned, would violate al- lowable increments of sulfur pollution on the reservation. In the three-year period analyzed, violations would have occurred on at least 19 days. Congres- sional changes in the Clean Air Act of 1977 allow one such violation. We thus had to deny the permits in the face of over- whelming local support for the plants as well as a strong re- gional and national interest in generating additional power. The final outcome of the Col- strip issue is not clear at this time. There is the possibility of further administrative action as well as litigation, but it does serve, again, as an example of the energy vs. environment dilemma Region 8 constantly confronts. The bottom line in this Re- gion 8 report must, of course, be the competence, courage., and dedication of Region 8 em- ployees in performing tasks of inestimable value for this coun- try in the face of something less than total acceptance of our role by much of the public. And therein probably lies our Region's greatest challenge in the coming months and years: building a broad-based con- stituency for the values we seek to serve, f This is the plains country EPA has been seeking to protect near Colstrip, Mont.
