The subcommittee met, pursuant to notice, at 2:35 p.m., in room 2154, Rayburn House Office Building, Hon. Dennis J. Kucinich (chairman of the subcommittee) presiding. Present: Representatives Kucinich, Watson, and Burton. Staff present: Jaron R. Bourke, staff director; Noura Erakat, counsel; Jean Gosa, clerk; Leneal Scott, information systems manager; and Jill Schmalz, minority professional staff member. Mr. Kucinich. Good afternoon to our witnesses and to all those in attendance. I am Congressman Dennis Kucinich, chairman of the Domestic Policy Subcommittee of the Oversight and Government Reform Committee. Our hearing today is going to be on assessing State and local regulations to reduce dental mercury emissions. I am pleased to be joined today by the distinguished Congressman from the State of Indiana, Representative Dan Burton, who I had the privilege of serving with in many different capacities over the last 12 years. Congressman Burton, thank you for joining us, sitting in as the ranking member today for Congressman Issa. This hearing today continues an examination that this subcommittee began last November into the detrimental impact of mercury on the environment. In particular, we are taking a closer look at mercury released from the dental industry and how State and local governments have worked to reduce those emissions. Elemental mercury and most of its compounds are extremely toxic substances that can cause chronic and acute poisoning in human beings who come into contact with them. Young children and unborn fetuses are particularly susceptible to mercury poisoning. Today, improper disposal of mercury into wastewater by industries and persons who use it has caused dangerously high contamination levels in many of the country's water bodies. The dental industry contributes substantially to the amount of mercury that ends up in wastewater and eventually in fresh water. In places where the disposal of dental amalgam is not subject to regulation, amalgam is frequently discarded by simply washing it down the drain. Last November, the subcommittee held its first hearing on this matter, where it heard testimony from the EPA, as well as the Food and Drug Administration. In the aftermath of the hearing, the FDA set a deadline to issue a final regulation on the reclassification of dental amalgam and its components, which would increase FDA oversight of dental amalgam. We are pleased with the FDA's decision to issue this proposed rulemaking. During our first hearing, we learned that dental offices constitute the largest source of mercury in wastewater influent. Once in the wastewater, mercury contaminates the environment in several ways. Most of the mercury entering the wastewater stream concentrates in the sewage sludge, 60 percent of which is spread over land as fertilizer; 20 percent is incinerated, resulting in the atmospheric release of mercury; and 15 percent is land-filled. The mercury that does not concentrate in sludge is discharged to downstream surface waters along with the treated effluent, namely into lakes, oceans, streams and land. We have also learned that a number of States and municipalities have made attempts at preventing the release of dental mercury from dental offices. Subsequently, the subcommittee took a closer look at State and local efforts aimed at reducing dental mercury emissions. The subcommittee surveyed nine States and eight local governments that have attempted to do so and found that when States evaluated the cost and benefits of choosing how to prevent environmental emissions of mercury, they all found that the most economical means for doing so was to prevent the dental mercury from entering their wastewater, as opposed to removing mercury from the wastewater. The technology used to capture mercury in the dentists' offices before it enters the wastewater stream is the mercury amalgam separator. Our survey revealed that to prevent dental mercury from entering municipal wastewaters, State and local governments have either encouraged voluntary use or mandated the use of separators. Our findings indicate that successful voluntary programs were incentivized programs that offered less cumbersome compliance requirements and were underpinned with the threat of a mandatory program. Moreover, most of the State and local governments that we surveyed initiated a voluntary program before enacting provisions in the form of a regulation, ordinance or statue mandating the installation of separators and a recycling program. Only after the failure of their voluntary programs to achieve their desired compliance goals did these governments switch to a mandatory program. Today we are going to hear from several of those States and local government representatives about how they grappled with these challenges, what were their lessons learned and how their regulatory experience can help States and local governments seeking to reduce dental mercury discharges to their wastewater. We will also hear from the American Dental Association. The ADA constitutes one of the most significant stakeholders in the effort to reduce dental mercury emissions. As we will hear today, among the most valuable lessons learned in the effort to achieve compliance is the importance of the cooperation and leadership of local and State dental societies. The ADA has already made significant strides in leading the effort to reduce dental mercury emissions. Most recently, it amended its best management practices to reflect its endorsement of amalgam separators as an effective tool to reducing mercury contamination from the dental industry. The ADA writes that ``the use of separators will allow greater recycling and reduce the amount of amalgam which contains mercury entering wastewater treatment plants.'' Some of the questions we hope to address in today's hearings are: First, what is the impact of dental mercury on the environment? Second, what is the efficacy of amalgam separator units? Third, what is the cost-benefit analysis of amalgam separators made by State and local governments? And, fourth, what are the considerations to make when deciding between a voluntary and a mandatory dental mercury reduction program? The subcommittee looks forward to hearing the testimony of witnesses today, and we will continue our investigation of how State and local governments can effectively reduce dental mercury emissions. At this time I would like to introduce the gentleman from Indiana, Congressman Burton, for his opening statement thank, Mr. Burton. [The prepared statement of Hon. Dennis J. Kucinich follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Burton. Thank you, Mr. Kucinich. Dr. Fischer, it's good seeing you again. Haven't seen you for a while. I will tell you a little story. This weekend I had a cap come off of one of my teeth, and I had to call my dentist for an emergency so he could put that cap back on. But when I got there, I asked him, I said, ``What kind of a filling do I have in that tooth that was under that cap?'' He says, ``Well, it's an amalgam.'' I said, ``Well, that's partially mercury, isn't it?'' He says, ``Yeah, but it's inert, and it can't cause you any problem.'' I just want you to know that it split, and a lot of that came into little bitty chunks and it got in my mouth, and I had to rinse it out. I was thinking, as I was rinsing it out, I wonder how much of this I am going to swallow and what kind of an impact it might have on me later in life. And I had to have him go ahead and put the cap on it, so it is still there. So, Dr. Fischer, I may be coming to you to have to get that out of there, because I had to have my tooth fixed over the weekend. But that's an example of--and he is a very good dentist; don't misunderstand. He is trying to do what he thinks is right, and he gets his direction from the ADA, who doesn't like me very much. You guys worked hard to beat me in the primary. I just want you to know you didn't win. But, anyhow, the thing about mercury is it is toxic, and it shouldn't be in our drinking water, it shouldn't be in our teeth, it shouldn't be in our vaccines, it shouldn't be in anything that goes into the human body. There's just no question, it shouldn't be in anything that goes into the human body. And even the FDA--I guess it was the FDA--the U.S. Food and Drug Administration just recently said they no longer ignored the science after dodging its duty to classify mercury fillings for decades. The U.S. Food and Drug Administration recently settled a lawsuit with several consumer groups promising to complete its end of the settlement within a year. As part of the settlement, the FDA has even publicly withdrawn its claims that amalgam is safe for all. And now it warns, ``Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses.'' Well, what about the person who has it in their mouth? You know, we had hearings on this for 2 years, Mr. Chairman. When I was chairman of the Government Reform Committee, my grandson became autistic. And I started looking into the mercury that was going into the human body, and I found that the vaccinations that children were getting contained 50 percent ethyl mercury and what was called the thimerosal preservative. And it used to be kids would get, you know, two or three vaccinations and then go to school. When I was a kid, if you had measles, it was a quarantine, or chicken pox or anything. Today, they give you vaccinations for all of that. And, as a result, children get as many as 28 to 30 vaccinations before they start to school. And, as a result, we have gone from one in 10,000 children that are autistic to one in 150. It is an absolute epidemic in America. And those kids are going to grow up, and they are going to get older, live to maybe 70 or 75, and be a burden not only to their families but on society and the taxpayers, because they are going to need help. And we still have mercury in adult vaccinations, and we have been able to get it out of almost all of the children's vaccinations except three or four. But a lot more needs to be done, and that's why I congratulate you on having this hearing. Representative Watson, your colleague on the Democrat side, who unfortunately couldn't be here today, she worked on this very hard in California. And she was able to get legislation passed out there that dealt with the mercury in dentistry, so that California is way ahead of the Federal Government and the ADA on this issue. I understand that other substances that they have put into our teeth may have some side effects. I have heard the ADA before, when we have had these hearings before, and there are some things that people should be concerned about. But mercury is the most toxic substance aside from radioactive material in the world. If you spill it on this floor, they are going to evacuate the building. They did that in high school in a science class here in Washington, DC. They spilled some on floor, they cleared the room, they evacuated the school, and they took the kids who had the mercury spilled on the floor near them and burned their clothes and had them watched by doctors for a long period of time. I am anxious to hear from our witnesses today. I have heard most of you before, and I am sure I am going to hear pretty much the same kind of testimony I have heard before. But I really do appreciate Dennis Kucinich, the chairman of this committee, who ran unsuccessfully for President but nevertheless he has a national following now. And even though Dennis is in the other party, him holding a hearing on this, I think, will bring far more attention on the subject. And I really appreciate him holding the hearing. Mercury should not be ingested in the human body in any way. One more thing, in Newport News, Virginia, when we were holding these hearings, the dentist down there, when they did the dental work on the naval personnel, they evidently were letting a lot of the mercury get into the wastewater system. And so the wastewater treatment system down there, the people that were head of the Newport News, Virginia, went to the naval leaders at Newport News and said, those all have to be put in containers, they can't allow any of the amalgams to leach into the water system because it was getting into the recycling system and it was getting into the water and causing problems. And so they started making sure it was put into lead-covered containers so it couldn't get into the system down there. That tells you pretty clearly that the residual impact of mercury fillings, even if you could keep them inert and wouldn't hurt you in your mouth, certainly hurt when they get into the ecological system, the water systems. And if you burn them in an incinerator, they get into the air. And so mercury should be not allowed to be put into amalgams or into the human body in any way. I am sorry if I droned on a little bit too long, Mr. Chairman, but when you have a grandson---- Mr. Kucinich. The gentleman is entitled to take whatever time he thinks is necessary. Mr. Burton. Well, thank you. But when you have a child who is a normal child, and he is your grandson, and he gets nine shots in 1 day, seven of which have mercury in it, and he becomes autistic within just a short period of time, and you have hearings on it for 2 or 3 years, and you find out from leading scientists and doctors from all over the world that the mercury in the vaccinations was a contributing cause, they believe--and there have been studies that show it does--that it's a contributing factor to autism, mercury in the amalgams. We had scientists from all over the country and the world come in and talk about the leaching effect of the vapors from hot and cold water getting into the mouth that could cause neurological problems from the mercury amalgams that are in people's teeth. And so this is a very big issue. It's one that is not focused on very often. And I really appreciate, Mr. Chairman, you taking the lead on this today. And I want you to know that, as long as you do this and as long as I am in Congress, I will do everything I can to get mercury out of everything that goes into the human body. Thank you, Mr. Chairman. Mr. Kucinich. I want to thank the gentleman for his passionate opening statement and also to indicate to you that this subcommittee is going to have an ongoing interest in this. The gentleman from Indiana and I have had other conversations about exploring the research and the causative effects of autism. I want to thank you very much, Mr. Burton, for the heart that you put into this. Thank you. Mr. Burton. Thank you, Mr. Chairman. Mr. Kucinich. Without objection, Members and witnesses may have 5 legislative days to submit a written statement or extraneous materials for the record. Since there is no other Member seeking recognition, we are going to go to the witnesses' testimony. I want to begin by introducing our first panel. Mr. Michael Bender is the director and cofounder of the Mercury Policy Project. Over the past 12 years, Mr. Bender has worked extensively on reducing mercury uses, reduce trade and exposure at the State, national and international levels. He serves as cochair of the State of Vermont Advisory Committee on Mercury Pollution, where he has represented the Abenaki, a local indigenous tribe, since 1998. Dr. Rich Fischer is the former president of the International Academy of Oral Medicine and Toxicology. He has published scientific papers internationally, and in 1998 he authored a chapter in the British dental textbook entitled, ``Complementary Therapies in Dental Practice.'' Dr. Fischer is also a member of several professional organizations, including the Academy of General Dentistry, the American Academy of Biological Dentistry, and the National Academy of Research Biochemists. Mr. Curt McCormick is the former administrator of the Environmental Protection Agency's Clean Water Act Industrial Pretreatment Program in Region 8. He worked for the EPA as an environmental scientist from 1987 to 2007, during which time he conducted hundreds of inspections of local government pretreatment programs and industrial facilities. Mr. McCormick is currently the owner of CWA Consulting Services and a board member for the Consortium for Research and Education on Emerging Contaminates. Mr. William Walsh--welcome--is legal counsel for the American Dental Association. He is of counsel in the Washington office of Pepper Hamilton LLP, where he heads the office's environmental practice group. He is also a member of the firm's sustainability and climate change team. His experience encompasses all major Federal environmental statutes and many State and local environmental laws, as well. I want to welcome all of our witnesses and thank you for appearing before the subcommittee today. It's the policy of the Committee on Oversight and Government Reform to swear in all the witnesses before they testify. I would ask that all the witnesses please rise and raise your right hands. [Witnesses sworn.] Mr. Kucinich. Let the record reflect that the witnesses answered in the affirmative. I will ask that each of the witnesses now give a brief summary of the testimony. Please keep this summary under 5 minutes in duration. And I want you to keep in mind that your presentation is very important. We want to be able to have it on the record, and we will, because your written statement is going to be included in the hearing record. So if you can present for 5 minutes, everything else in the record. Let's start with Mr. Bender. You are our first witness. Please proceed. STATEMENTS OF MICHAEL BENDER, DIRECTOR, MERCURY POLICY PROJECT; RICHARD D. FISCHER, FORMER PRESIDENT, INTERNATIONAL ACADEMY OF ORAL MEDICINE AND TOXICOLOGY; CURT MCCORMICK, FORMER ADMINISTRATOR, ENVIRONMENTAL PROTECTION AGENCY REGION 8; AND WILLIAM WALSH, COUNSEL, AMERICAN DENTAL ASSOCIATION STATEMENT OF MICHAEL BENDER Mr. Bender. Thank you, Mr. Chairman, members of the committee. My name is Michael Bender. Mr. Kucinich. You know what? I am sorry. Before we begin, I want to ask if--Congresswoman Watson just entered the room, and she has done so much on this. Did you want an opening statement, Congresswoman? Ms. Watson. Yes. Mr. Kucinich. OK. The Chair is going to use his prerogative to go to Congresswoman Watson, who has done a lot of work on this issue in the State of California, as Mr. Burton noted. And so, Ms. Watson, when you are ready, you may proceed. Just take your time. Thank you. And then we will return to you, Mr. Bender. Ms. Watson. Mr. Chairman, thank you so much for your leadership and your hard work on this issue and for holding this hearing. And I want to thank all of the witnesses for being here today. Mercury is a toxin. And we all are concerned about the welfare of the patients, but I am also worried about the long- term effects of exposure to mercury to dentists and to the staff. For many years, there has been a research study on this very topic, and it was discovered that all dentists and staff who either replace or remove mercury fillings have extremely high levels of mercury in their systems. Some of the dental offices do not insert mercury fillings; they only remove them. Therefore, they are breathing in the mercury vapors and dust, and a regular mask does not help. One needs to wear a respirator. And this toxic material enters their systems via the respiratory tract. Absorption through the skin is another mode of transport. Dentists and staff, when compared to the general population, have a large mercury content difference. And it is not because they eat a lot of fish. Forget about the aesthetic component; the need of the dentists and staff, the health aspect, should be also a major concern. It's amazing to me that the EPA has not gotten involved with this. The long-term danger of mercury inhalation is as detrimental as dental mercury fillings in one's mouth. It makes you think we might be hiding something, doesn't it? And allow me to ask this question: Why is it that dentists have the highest suicide rate among any other health professional? Did you know that one of the side effects of mercury toxicity is depression and suicidal tendencies, known years ago as the Mad Hatter's Disease? I, myself, Mr. Chairman--and I am so pleased to see Congressman Burton here. We have been on this issue for years together, and I appreciate your interest and your focus and your being here. Look at the vacant seats. I, myself, did not know I was being poisoned for decades. I got my mercury fillings when I was 9 years old. And I noticed that I had these allergies to everything, that I was getting headaches, I was getting splotches in my skin. My skin was much, much darker. And so a group of researchers came into my office. They had been doing research in Europe. And they said, you know, have you ever been tested for mercury poison or vapors? They brought in the tester. It's a metal tube that goes down. And mine hit almost off the charts. I had to go to Mexico. I asked my own dentist about it, and he stuck something in my mouth and wouldn't even discuss it. And I have been going to him for 30 years. I went down to Mexico, and the dentist down there said he had to go to Mexico because he was to do 40 mercury fillings, amalgam fillings, he refused, and he couldn't pass his boards. So he went to the University of Mexico, passed his boards, lives in California but goes down to work there. So he explained to me. It took 6 weeks. I went from Washington, down to Mexico, to LA. That was my route, until the work was done. I looked like a different person. I went to the dermatologist. He said, I am going to pull out the poison through your skin. So, along with getting the mercury fillings out, they were going, the fumes were going up through my T- zone. I was having trouble remembering names. I said, what's wrong with me? I was being poisoned. I called in the National Dental Association, and they told me that black people didn't like to go the dentist, and so certainly they are going to continue to use amalgam fillings because they were cheaper. And I tried to explain to them what I knew scientifically; did no good. They were looking at cost. And I was just amazed. I said, you are going to put young people under risk? And they didn't seem to care. So I said, you take my bill. You take it home with you, look at it, and then you tell me how I can amend that bill to suit your needs. I got the same letter back from them that they sent in the beginning. So I see that profit for dentists--you know, don't make a wave. People won't know. We are dulling down our children's brains. And I think pregnant women, you know, whatever goes in here seeps through the placenta and has an effect on that fetus. And I think it's high time that any professional start looking at this. And I am surprised. The Environmental Protection Agency wouldn't really want to look at it seriously without our prompting? Senator--Congressman Burton--I just promoted you to Senator. And we were told in southern California, do not eat the tuna along the coast; it's infested with mercury. Do not eat it. Why? Because, as you know, the waste from dental offices go into the sewage plant and then out into the ocean. And so I am really, really concerned. We need to wake up to this new threat. And, again, Mr. Chairman, I wish to thank you for your leadership, your hard work. Mercury is an environmental disaster. It's the number-one toxic substance in terms of the WHO. And dentists have alternatives. They might be a little more expensive, but why would you want to take the risk and put a toxic substance in, particularly, a young person's mouth? Because you say it's well-sealed. Well, I haven't seen a child who hasn't fallen, cracked a tooth, or tooth is pulled, or whatever. And that mercury goes right up into your T-zone. So, Mr. Chairman, I know that we are going to be enlightened today, and I want to thank you. And I want to thank my partner over there, Representative Burton, for his interest, his focus, in setting this as a priority. Thank you very much. I look forward to hearing from the witnesses. Mr. Kucinich. I thank the gentlelady for her comments. Let's proceed with Mr. Bender. Thank you. Mr. Bender. Thank you, Mr. Chairman, members of the committee. My name is Michael Bender. I am the director of the Mercury Policy Project. We work locally, nationally and globally to eliminate mercury releases and the use of mercury and exposures to mercury. Next slide, please. In my brief presentation today, I am just going to recap some of the information that we have heard from the last hearing. First of all, that there's over 1,000 tons of mercury tooth fillings in Americans today that, when released, will pollute our environment. And mercury use is continuing. Second, nine States require dentists to have amalgam separators to reduce mercury into wastewater. That's one good step forward, and we will talk about others. Third, that the voluntary efforts are not effective at convincing dentists to install separators. They need some kind of an incentive. Fourthly, that the ADA and the State associations are reportedly blocking State and local amalgam separator initiatives, even though they voluntarily say they promote them. And then finally, we will summarize the discussion that the amalgam separators is the most cost-effective at controlling dental mercury pollution. We will also want to draw the committee's attention to a report we provided to the committee where we do a cost analysis. Representative Watson mentioned the higher cost of the amalgam separator. When you factor in the externalities, the cost of keeping mercury out of wastewater and keeping mercury out of the airstream from cremations and the costs of the amalgams aren't cheaper. In fact, they are comparable, or the composites are actually more cost-effective. So, next slide, please. This is a pie chart from the U.S. EPA where they have alerted us that there's over 1,000 tons of mercury walking around in Americans' mouths. It's the largest single current use of mercury in the United States today. Next slide, please. That dental mercury, on average, accounts for over 50 percent of the load of mercury into wastewater. And we see some examples there. And, again, this was background. I would like to move to the next slide, which is some new information that we just got from the Northeast Waste Management Officials' Association, the interstate mercury education and reduction clearinghouse. They just released the 2004 data on mercury uses from the amalgam manufacturers. Unfortunately, we are saddened to hear that the U.S. dentists are still using 30 tons of mercury annually in 2004, just as they were in 2001. This is significant because, contrary to what we have heard from the dental sector, their mercury pollution will continue unabated without controls. Next slide, please. Although you can't see this on this screen very well, you can see the actual numbers and that the dental mercury use is about 25 percent of all the use in the United States today. And it indicates the numbers from 2001 to 2004. Mr. Chair, these are actual numbers that were reported by State law from the amalgam manufacturers to the NEWMOA group. And so, unfortunately, we keep hearing from the dentists that they are reducing the use of mercury; we are not seeing it in the hard numbers. We have heard it anecdotally, and unfortunately we are not seeing it. Next slide, please. As I indicated earlier, there are State mandates for amalgam separators. Nine States require mandatory separator installation. Why? Because the voluntary programs aren't effective at convincing dentists to install separators. And there are numerous examples of this, and we will hear more of those today. Data from the Boston area showed a 48 percent reduction in mercury concentration and sludge as amalgam separator use increased from less than 20 percent to over 80 percent due to mandates. Next slide, please. The ADA unfortunately and apparently is continuing--even though they are now supporting these amalgam separator initiatives as a voluntary BMP, what we are hearing from their own news reports is that they are reportedly training their trainers to support these BMPs, best management practices, and, along the way, use this argument as a way to oppose the amalgam separator initiatives. The ADA and the State dental associations appear to have blocked amalgam separator initiatives in California, Wyoming, Michigan, Ohio, Montana and likely elsewhere, and they have slowed the requirements for installation in Oregon. They are also blocking local separator initiatives as well, as we know from their recent work in the city of Philadelphia. Next slide, please. In summary--I am sorry, I am jumping ahead of myself. I just wanted to emphasize Chairman Kucinich's statement about amalgam separators being very cost-effective. We had consultants do an analysis over a certain period of time, using 2005 numbers. The cost per filling for amalgam separators is an add-on cost of about $2 a filling. As I indicated earlier, we also did an economic analysis of the cost of putting the controls on the cremation. That will be $18 more a filling. So that's where the numbers add up, that, in fact, the amalgam is not cheaper. Then, finally, I would like to conclude with some information that's in our longer-term and our larger report that's available for the record, and it sort of reiterates a little bit of what Representative Watson was saying. In summary, the encapsulated dental amalgam is shipped from manufacturers to a dentist's office with a skull and crossbones affixed next to the word, ``Poison, Contains Metallic Mercury,'' MSDS 2007, from Dentsply. Amalgam manufacturers-- Kerr, Vivadent and Dentsply, among others--advise dentists against placing amalgam in the teeth of pregnant women, nursing mothers, children under 6, and anyone with kidney disease. Dentsply, for example, warns, ``Contraindication (`contraindication' is a directive to forbid, not just a `warning'): in children 6 and under and in expectant mothers.'' Dentsply also supplies a warning on their MSDS to dentists that amalgam is dangerous for the environment. And you can see a copy of their MSDS on a report that's on the table. But then that information apparently gets stuck at the dentist's office. We did a national poll. We hired Zogby International, and what we found is that most Americans, 76 percent, don't know mercury is a primary component of amalgam fillings; that 92 percent of Americans overwhelmingly want to be informed of their options with respect to mercury and nonmercury dental filling materials prior to treatment; and, finally, once they are aware that there is mercury in the amalgam, 77 percent of those surveyed would choose higher-cost fillings that did not contain mercury if given the choice. Mr. Chairman, I would like to join others and express my appreciation to you for holding this hearing. It's a very important topic area. I was joking that this dental sector seems to be one of the last sacred cows in the continued use of their justification for mercury. We know, from a ruling in Norway and Sweden just having banned amalgam in January 2008, that there is no reason to continue using amalgam. Those societies are just doing fine. They aren't having any kind of a health epidemic over there. They are doing very well. And they worked cooperatively with their dental association over a number of years to put controls on in their facilities and also to recognize that dental mercury is not appropriate in the human mouth. So what concerns me about the 30 tons of mercury that is still being used, which is 60 million mercury dental placements a year, is that I think that this dental sector is stuck in complacency, and it needs some kind of a regulatory incentive to move forward. Thank you, Mr. Chairman. [The prepared statement of Mr. Bender follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. Dr. Fischer. STATEMENT OF RICHARD FISCHER Mr. Fischer. Thank you, Mr. Chairman, Ms. Watson and Mr. Burton. Current estimates indicate that the dental profession uses about 40 tons of mercury per year in the fabrication of amalgam fillings. These mixtures emit mercury vapor continuously for decades and are the major contributor of mercury to human body burden. EPA requires that the excess unused newly mixed amalgam be handled as a toxic waste disposal hazard, just as it does the amalgam particles from removing old mercury fillings. There are four major routes by which dental mercury may come into contact with the environment. The first is dental clinic wastewater. The process of either placing or removing mercury fillings generates a slurry of mercury-rich amalgam waste, which is vacuumed into the chair-side suction unit. According to a recent study commissioned by the ADA, 6\1/2\ tons of mercury are released to wastewater treatment plants annually by dentists in the United States. This represents more than 50 percent of the total mercury entering wastewater treatment facilities. The IAOMT, recognizing that the dental profession has the opportunity and the obligation to eliminate or reduce this environmental hazard, urges all general dentists to install effective mercury separator equipment. We support efforts to make this a regulatory requirement, since efforts toward voluntary compliance by dental associations have failed. No. 2, air discharge. Mercury vapor has also been measured in air vented from the central vacuum systems to the outside of the dental office. An estimated one ton of mercury vapor per year finds its way into the atmosphere through this route in the United States. There is currently no known technology to prevent this form of pollution. No. 3, amalgam in human cadavers. The EPA estimated that in 2005 over 3 tons of mercury were released to the environment in the United States from crematoria. Four, human waste. Published studies have concluded that each and every amalgam bearer excretes an average of 100 micrograms of mercury per day in his or her urine and feces. Assuming two-thirds of this mercury is derived from dental fillings, then 5.7 tons of dental mercury annually are flushed directly into our wastewater. Again, there is no known technology to prevent this form of pollution, nor are there any regulations over this form of domestic waste. The above four routes of mercury entering the environment combined for at least 16 tons of mercury annually from dental fillings. Less than half of that total, the 6\1/2\ tons from dental wastewater, can be captured by best management practices and amalgam separators in dental offices, but then only if mandatory. Over 1,000 tons of mercury are implanted in the teeth of Americans nationwide. Assuming a 10- to 15-year average durability of these mercury fillings in patients' mouths, this enormous reservoir of mercury will be continuously flushed into the environment for decades to come. Organized dentistry has established best management practices for managing hazardous waste. These practices have had disappointing participation by dentists when purely voluntary. For example, in the Seattle/King County area of Washington State, after 5 years of promises from local dental societies, 2.5 percent of offices had complied. Currently, 11 States in various municipalities have replaced their voluntary programs with mandatory regulations, resulting in nearly 100 percent compliance. In those States and municipalities where amalgam separators are required, there has been a 50 percent reduction in the amount of total mercury from all sources entering wastewater treatment plants. When considering whether or not an amalgam separator installation should be voluntary or mandatory, we should consider information published in the fall edition of the ADA Professional Product Review. There it was reported that, ``A survey of members showed that relatively few panel members own an amalgam separator or plan to purchase one.'' I have been practicing dentistry for 35 years, the last 26 without using mercury fillings. I stopped using them when I discovered that the mercury was not locked in the fillings, as I had been told in dental school. I purchased an amalgam separator approximately 15 years ago when I discovered that this technology was commercially available. As a health professional, I am ethically bound to err on the side of caution for my patients, my staff, my colleagues and my environment. To place a mixture containing 50 percent mercury, the most neurotoxic element known on Earth, within inches of a child's brain stem and assume it's harmless is, at best, counterintuitive. To release the same pollutant into the wastewater is irresponsible when simple and available technology exists to reduce that release by over 95 percent. But that still leaves more than half of the dental-derived mercury that is dumped into the environment that remains beyond our ability to capture. We all remember the character The Mad Hatter from ``Alice in Wonderland.'' The character was based on the historical observation of workers who made felt hats in Connecticut in the 1800's. The workers, or hatters, used mercury nitrate to shape the hats. The hatters frequently suffered from shakes, hallucination and dementia or madness due to that mercury exposure. The hatmakers stopped using mercury in 1943. It's now 2008. It's time for dentistry to stop the madness. Until dentistry joins the rest of the 21st-century health-care profession and abandons its use of mercury, there can be no effective environmental solution to the dental mercury crisis. Thank you.

Good afternoon, Mr. Chairman, Mr. Burton, Ms. Watson and members of the subcommittee. I am Curt McCormick. I currently own a small business. But I think I was asked to show up today because I just recently retired or left the Environmental Protection Agency, the Denver office of the EPA. For 17 years, I was regional pretreatment coordinator there, which is a program which regulates local governments and requires that discharges to their sewer systems are controlled for pollutants. I also worked on a mercury-control strategy for the region. EPA in Colorado, Wyoming and Montana was the primary pollution control authority on municipalities, as the States do not have authority or do not authorize that program. I want to preface my comments today that, while I probably will be mentioning the ADA in some parts of this, I don't believe the ADA did anything inappropriate in their lobbying of Region 8 or EPA headquarters. I think most of my comments are directed toward the internal EPA process of developing guidance and providing technical assistance. I have to admit that the ADA was fairly tenacious in its efforts. And the outcome of their lobbying was fairly surprising in some areas, which I will go into. Your subcommittee has heard the testimony of EPA and others in the past about the importance of reducing mercury in the environment and contribution of dental waste amalgam. One EPA senior manager referred to the Clean Water Act pretreatment program, and that is the program I oversaw for much of my career. This federally mandated program makes controlling the discharge of mercury and other pollutants into a sanitary sewer system a regulated and local responsibility. While EPA Region 5, which was the Chicago office, the Great Lakes initiative, had acquiesced to the ADA's position that treatment not be a requirement for controlling dental discharges, EPA Region 8, which is the Denver office, we did not opt to adopt that voluntary approach to controlling mercury. We had a more mandatory requirement in the guidance that we developed. Our premise was that where a problem exists with a specific pollutant, local government pretreatment programs were required to control discharges of this pollutant into the sewer system. This approach is clearly reflected in the regulatory objectives of the pretreatment program that implement the Clean Water Act. As mentioned earlier, the ADA focused its efforts on all levels of government. And Jerry Bowman, assistant general counsel for the ADA, attended and spoke at a public hearing at a city council meeting in Laramie, Wyoming. The city intended to adopt mercury controls to address problems at their wastewater plant. Presentations by myself and the city pretreatment staff, in addition to local support by other locally regulated industries, was enough to assure that Laramie City Council that the Region 8 approach was consistent with their local regulations and a fair approach that included dental offices as part of a solution to an identified mercury problem. This outcome intensified the ADA efforts to work through the EPA Office of Water. In a letter to Ben Grumbles dated February 16, 2005, the ADA made it clear that they were very unhappy with the lack of progress that EPA headquarters had made in stopping my program's efforts. The ADA opens the letter stating, ``We appreciate the opportunities you have afforded us in the past. On December 15, 2004, representatives of the American Dental Association were able to spend approximately an hour with you discussing, among other things, the association's deep concern with the contemplated approach of EPA Region 8 to dental wastewater. As we discussed, the region's draft guidance, on which the ADA submitted extensive comments, prohibits the very type of voluntary partnership which the administration otherwise supports. Moreover, the draft guidance requires amalgam separators whenever a POTW has a need to address mercury. At the end of our meeting, you indicated that you would speak to the Region 8 administrator on these topics. We have not heard back from you.'' The letter continues with references to Region 8, its proposed mercury control efforts, and a concern that Region 8's approach will influence the rest of the country. EPA Region 8 senior management responded directly and independently to the ADA in an April 22, 2005, letter stating that the Region 8 supported the approach by my program and that the final document would continue to be consistent with the Clean Water Act and its implementing regulations. I have not seen copies of any responses by the Office of Water on the February 16, 2005, ADA letter. However, after the Region 8 letter of April 22nd, I was informed by my Region 8 senior management team that my program strategy document would not be issued final. The message was that the Office of Water did not want it published final. Region 8 senior management told me that the draft version of the document would be made available to anybody requesting a copy and would be posted for download on the Internet. And it currently is still available, the draft, for download on the Internet. Regardless of the status of that document, my program, I continued to approve local programs, mercury-control regulations so that they would fully implement amalgam separator requirements where necessary. But the stoppage of this document put a dampening effect on some of the POTWs or on some of the cities adopting it. I will wrap up here quickly. I left the EPA in October 2007. I have written newsletters on interest groups and the regulation of mercury. A current one discusses a State of Michigan bill that allows for self- regulation of dental dischargers. This bill specifically prohibits the State-mandated pretreatment programs from requiring any more stringent than what the State dental association deems necessary. EPA has been notified of this legislation and has taken no identified action to ensure that this bill will be consistent with the Clean Water Act. In conclusion, I believe that many scientists and regulators at EPA are perplexed at the evolving level of influence at the decisionmaking levels within EPA. As with other EPA staff, I took seriously the oath to uphold the law and believe in the mission of the EPA, even now having left the agency. However, I believe that there's a reinterpretation of that mission which has and will continue to result in the eroding of credibility and the loss of experts from the agency. Mr. Chairman, this concludes my statement, and I will be happy to answer any questions you or your colleagues have. [The prepared statement of Mr. McCormick follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. I thank the gentleman. Mr. Walsh, you may proceed. STATEMENT OF WILLIAM WALSH Mr. Walsh. Thank you, Mr. Chairman, Mr. Burton and Ms. Watson. Thank you for the opportunity to speak today. I am William Walsh from Pepper Hamilton LLP, outside counsel for the American Dental Association on amalgam wastewater issues. I have represented the ADA on these issues since 2001. The ADA is the world's largest and oldest dental association, representing more than 155,000 dentists nationwide. The ADA has issued and continually updates, as appropriate, its best management practices for handling waste amalgam. These BMP call for the use of standard control methods, recycling of collected amalgam and, since last fall, the use of amalgam separators. Even without separators, dentists capture in their office approximately 80 percent of the waste amalgam, with almost all of the remaining 20 percent being captured by wastewater treatment plants before the wastewater is discharged to surface water. In other words, 99 percent of the amalgam is already captured prior to discharge from the POTW. Adding a separator allows the capture of that additional waste in the dental office instead of at the wastewater treatment plant. The ADA has devoted substantial time and resources to promoting its best management practices. For example, in 2001, the ADA commissioned an independent study to determine how much mercury might be entering the surface waters from amalgam wastewater discharges. The ADA evaluated the effectiveness and the cost of amalgam separators, including contributing to the development of standards for testing separators that were being developed by the International Standards Organization. In 2003, ADA proposed to the Office of Water to initiate a voluntary amalgam wastewater reduction program in partnership with EPA, and has continued those discussions. The ADA proposed to EPA and participated in developing a standard for recycling amalgam waste that is collected in the offices. The ADA has conducted a comprehensive outreach and education program for dentists and dental societies, including numerous seminars for dentist and dental societies, articles in the ADA News, the peer-reviewed journal of the American Dental Association, and the ADA Professional Product Review, partnering with EPA to produce and distribute BMP brochures and videos to 43,000 dentists in the Great Lakes region in 2005. Several factors favor ongoing efforts. First, the dentist industry's goals as of last fall comport exactly with those of the government to minimize dentistry's discharge of amalgam waste. Second, dentists, as health professionals, would respond to scientific evidence and cooperative approaches. Some of the early efforts were not successful because of the lack of understanding on both sides. But the ADA and dentistry have learned from this past experience, they have calibrated their approach, and voluntary and cooperative partnerships have succeeded in some of the subsequent efforts. Third, according to the 1997 report to Congress by EPA, dentistry contributes to less than 1 percent of the total mercury found in our lakes and streams--0.4 percent mercury in surface waters. Fourth, mandating separators would require a costly inspection and enforcement apparatus, given that there are some 100,000 dental offices that would need to be regulated. Fifth, nothing precludes in the proposals that the ADA has made the State or local agencies for enacting mandatory programs, should voluntary efforts fail. As the testimony submitted by some of the other witnesses indicate, many of them encourage cooperative efforts between the regulators and the local dental associations to determine whether mandating separators in a dental office is appropriate. And we think that decision is best left to the local authorities. Dentists drink and fish and swim in the same waters as everyone else in their communities, and they believe that ongoing efforts to encourage the use of BMPs, which includes separators, are succeeding and will continue to increasingly succeed. In closing, dentists have steadily reduced their already- minimal contribution to metal mercury discharges to surface waters over the past decade. They bring to these efforts the same commitment they bring to providing the best possible oral health care to the American people. I will be pleased to answer any questions you might have. [The prepared statement of Mr. Walsh follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. I thank the gentleman. I just want to remind all the witnesses that this Chair takes it very seriously when witnesses rise and take an oath to tell the truth. I just want you to understand that. I also want to ask the members of the committee, without objection, if each of us may proceed for a period of 10 minutes for the questioning of the witnesses. Without objection, so ordered. I am going to begin here and ask some questions of Mr. Walsh. I want to say that the subcommittee appreciates your participation on behalf of the ADA, because we are dealing with a matter that cannot be addressed without the participation and cooperation of the dental community. After listening to your testimony, I am somewhat confounded by the substance of it, because it seems that the ADA is at odds not only with the witnesses on this panel and the next panel but also with its best management practices, which recommend the use of amalgam separators. And this committee is going to ask you to help us understand. I want to begin with the impact of dental mercury emissions on the environment. Now, in your testimony--and you said it twice in the last minute--you said that dentistry plays a very small role in the overall issue of mercury in surface waters. Today, we have been discussing the impact of dental mercury emissions into the environment from wastewater, not surface water. Testimony for today's hearing indicates that dental mercury emissions constitute about 40 to 50 percent of the mercury found in wastewater, far exceeding the level of mercury discharge from all other commercial and residential sources. Mr. Walsh, do you agree with this finding, that dentistry is the largest contributor of mercury to municipal wastewater? Mr. Walsh. Yes, we do. The study we commissioned that I mentioned in my testimony determined that between 40 and 50 percent of the mercury from amalgam discharged into wastewater treatment plants---- Mr. Kucinich. OK, I am glad that you agree, because I have here a statement that agrees with your position. The World Health Organization that says that one-third of the mercury in the sewage system comes from dental amalgam flushed down the drain. And, more discretely, the Association of Metropolitan Sewage Agencies found that dentistry contributed 40 percent of mercury into wastewater, over three times the next greatest contributor. And so, in your opinion, Mr. Walsh, does dentistry play a significant role in mercury contamination into the environment? Yes or no? Mr. Walsh. No, because the wastewater treatment plant removes 95 percent of that mercury that goes into the wastewater treatment plant. You are looking at influent numbers, also the amount that may be collected in the sludge. The reason it is being collected in the sludge is it is not being discharged through. The study I mentioned looked at both the effect of incineration of the sludge for the 20 percent of the sludge that is incinerated, as well as the direct discharges. Mr. Kucinich. Thank you. To the other panelists, I would like you to respond to that, starting with Mr. Bender. Keep it brief, please. Mr. Bender. Wastewater treatment plants aren't set up to treat hazardous waste. It's very clear that most of the mercury ends up in the sludge, and the sludge gets incinerated or it gets land-applied or it gets used as a soil amendment. And there are a number of studies out there, which are in my previous testimony, I can provide to the committee, which indicate that mercury gets released into the environment; it does not get captured. Mr. Kucinich. Dr. Fischer. Pull that mic closer, please. Dr. Fischer. I would agree that 95 percent of the mercury in the wastewater from the amalgam does settle, but then it just goes from one pocket to another. I mean, I mean it's not reclaimed, recycled or captured in any way that's effective. It's been just put back into the environment in some other manner. The wastewater treatment plants aren't alchemists. I mean, mercury comes in; mercury's got to go out somewhere. Mr. Kucinich. Mr. McCormick. Mr. McCormick. Now, from a regulatory standpoint, all you're doing is disposing it from one media to the next. You're not actually reducing discharges to the environment. You are just sending them out either through the solids, through land application, incineration, generally through biosolids, so---- Mr. Kucinich. Mr. Walsh, I want to ask you again, considering that dentistry is the largest contributor to mercury in wastewater and in light of the fact that once in wastewater mercury becomes part the sludge that is incinerated, landfilled or sprayed over the land, volatilized in some way, would you agree that dentistry does in fact play a significant role in mercury contamination into the environment? Mr. Walsh. No, because when we looked at various studies that had been done---- Mr. Kucinich. OK. I'm going to go on. I'm going to go on with my questioning. In your testimony, you also say that, ``even if a dentist installed a separator, it would have little effect on the environment because amalgam is ultimately captured at the treatment plant.'' I want to ask you a few questions about this. Are you suggesting that mercury discharged into wastewater is not an issue because it can be treated before the water is released into the effluent? Mr. Walsh. I'm suggesting that if the impact is surface water, which is what the impact---- Mr. Kucinich. The question is---- Mr. Walsh. If you prevent that---- Mr. Kucinich. You keep on drawing a distinction between wastewater and surface water, but you're talking about surface water. This hearing is about the effect on wastewater. This is the point that I'm asking you; I'm asking you again, are you suggesting that mercury discharged in the wastewater is not an issue? Wastewater, you know the difference. Can you answer the question, yes or no? Mr. Walsh. I know the difference between wastewater and the surface water. Mr. Kucinich. Can you answer the question, yes or no, sir? Mr. Walsh. The wastewater is what is going into the POTW. It is captured. It is not discharged. The limits and the regulatory requirements are based on protecting the surface water and protecting the fish that are in the surface water. So it's relevant that the wastewater is in fact captured, whether it was originally designed, POTWs do in fact, and there is data that NACWA has done, many studies looking at many different treatment plants---- Mr. Kucinich. This is one chairman who isn't going to let you run out the clock. Mr. McCormick, what about the wastewater and mercury capture at the publicly owned treatment works? Mr. McCormick. Well, as I indicated before, it is partitioned primarily--or it settles--it absorbs primarily to the sludge. I would have to take a little bit of an issue in that water quality, surface water quality, is one criteria that drives limits. However, I think what isn't being talked about is there are also standards for biosolids for mercury. There is--there are various standards that have to be met. And while surface water quality is one standard that has to be considered, I think biosolids or sewage---- Mr. Kucinich. I want to go back to Mr. Walsh. Mr. Walsh, is it true or not that the International Academy of Oral Medicine and Toxicology has said that wastewater treatment facilities are not designed to process or handle heavy metals? Mr. Walsh. I don't know that particular reference, but I think the statement is correct that they were originally designed in the turn of the century to treat wastewater. The physics of the amalgam particles and the data that has been looked at across the board by the National Association of Clean Water Agencies show that in fact because of that physics 95 percent plus of the amalgam particles are captured in the sludge, as was indicated. And in fact NACWA has said, looking at the mercury levels in biosolids across the country, that there are today, as a result of a number of mercury reduction programs, the levels are well below EPA's standards for biosolids. Mr. Kucinich. Well, we've received--as members of this committee, we've received testimony from several representatives of municipal wastewater plants. And in that testimony, we are told that precisely because wastewater plants cannot adequately remove mercury, the respective sewage district adopted a prevention policy and began with its dental community, who constitute the largest contributors of mercury to wastewater. Does everyone have this wrong, Mr. Walsh, or are we not understanding something about your presentation here? Could you help us a little bit? Mr. Walsh. The, particularly in the Great Lakes, which have---- Mr. Kucinich. Can you be close to the mic? Mr. Walsh. Yes. Particularly in the Great Lakes, there is a very low water quality standard; I believe it is 1.3 parts per trillion. The level of mercury in rain, mainly from combustion sources, some of them outside the United States and some in, exceed that level. So the municipalities were faced with a tough problem; the level cannot be reached no matter what the discharge is. And in those areas, many of the municipalities are using a variety of techniques to try to get their sources to reduce the levels. And so--but there are other areas where there are aren't such low water quality standards, and there are no biosolids limits being exceeded, and there are no discharge surface water quality levels being exceeded. And in fact, the fish are not being--containing levels that are above the level. But remember, the ADA has taken the position that we should--every dentist in the country should in fact install a separator; that, as has been said, it is better to recycle this material; and that the preferable way is using the good offices and resources of the ADA to help communicate these requirements to the thousands of health and dental professionals to work cooperatively with government for the mutual goal. The goal here now is the same now. Admittedly when we started our discussions and were educating ourselves as to what was happening, the goal wasn't the same. But the goal is now the same: Gather as much of this as possible in the dental offices, get it recycled. There is a difference as to whether a voluntary program initially, as is always true in a voluntary program, the potential of it becoming mandatory is the preferable way. And we have to think for a number of reasons that it is preferable, but I think there is more agreement now than there has been historically on what to do. Mr. Kucinich. I thank the gentleman. I just want to conclude this round of questioning for myself by making this observation, and that is that you've said that the ADA supports the use of separators because they prevent, and this is a quote, a significant amount of waste amalgam from being deposited in wastewater treatment biosolids. And if the plants will treat the water in any case, then, you know, it is obvious, why would the ADA support the use of separators? What's happening here is that, while your best management practices say that, you focus on the word ``voluntary.'' That's where you're holding on to that for dear life, voluntary as opposed to mandatory. But we're talking about a neurotoxin here. Now I can understand and I've had debates with my Republican colleagues on the whole issue of regulation. And you know, there are some honest debates about it. How far do you go with regulation? But this is a particular area that has to do with a substance that has been found to not just be a neurotoxin, but that particular neurotoxin is associated with a whole other range of serious health implications. And so the questions of this subcommittee are going to challenge your position on the--I'm assuming will challenge your position on the difference between voluntary participation and mandatory. And it becomes particularly important since the ADA itself has taken a position that you support the use of separators. So the Chair recognizes Mr. Burton. I took 13 minutes. You can have the like amount. Mr. Burton. Thank you very much. The Association of Metropolitan Sewage Agencies estimates it costs as much as $21 million per pound to safely remove mercury once it becomes part of the wastewater stream. The Environmental Protection Agency estimates that sewage sludge nationally contains about 15 tons of mercury per year from all sources, not just dental amalgam. However, the Association of Metropolitan Sewage Agencies estimates that 35 to 40 percent of the mercury load comes from dentists. That's roughly 6 tons of mercury. At 2,000 pounds per ton, that means it costs taxpayers roughly $252 billion per year to remove dental mercury from sewage sludge. In contrast, the company Solmetex sells amalgam separators priced from a low of $715 to $2,490. If every one of the 155,000 members of the American Dental Association purchased an amalgam separator, it would cost anywhere from a low of $110.835 million to a high of $38--385.95 million one time only. Wouldn't you agree the most cost effective solution is to simply stop mercury contamination at its source within a dentist's office? Mr. Walsh. We looked at the cost effectiveness, but I believe the numbers you are quoting is if a POTW had to do additional reduction to meet numbers like the Great Lakes water quality standard of 1.3. The existing cost to POTWs, since their sludge levels are not exceeding the regulatory levels that were based on risk, as I understand it, is nothing. The plants, as designed, although that wasn't the purpose of the design, in fact collect the numbers we are talking about. Separators collect slightly more; it is an additional amount of collection. When you look at using the same kind of methodology that EPA uses, and you have to include the cost of recycling all of the amalgam that's collected because that's part of the cost, it is actually higher than it would cost to reduce mercury emissions from coal-fired plants. Despite that, the ADA has taken the position---- Mr. Burton. Do you have any amalgams in your mouth? . Mr. Walsh. Yes, I do. Mr. Burton. Do you? Do you remember when they put those amalgams in your mouth? Mr. Walsh. I remember generally. It started when I was a child, and I have quite a few. Mr. Burton. Do you remember when they mixed it up, they put the mercury in and they mixed it up with this little machine; do you remember that? Mr. Walsh. I actually don't remember that. I know that was the practice until recently. Mr. Burton. I remember how they did it. They mix it up, and the dental assistant mixes it, and they put it in this thing, and then they put it into a device that inserts it into your cavity. And when put that into your cavity, they say, well, it is going to be inert; it is not going to cause any problems. But every time I every had an amalgam put my mouth, there was a lot of it that squished out and went into my mouth. And then I would rinse it out after they--while they were doing it, and we would spit it into the water container. And you know where that mercury goes then, don't you? Mr. Walsh. Yes, it goes down into the sewer system. Mr. Kucinich. It goes down the sewer system. Mr. Burton. The sewer system. What about the mercury that doesn't go down the sewer system that you swallow, because you can't get it all out? Does that have any impact on a human being? Mr. Walsh. Well, my testimony is focused on the environmental. I am an attorney. I think it would be beyond my capacity to testify on---- Mr. Burton. Well, let me just tell you, it is my belief that if you consume mercury in any form or have it injected into your body, it is a contaminant that can cause neurological problems. And that's why I believe that they shouldn't be putting amalgams in a person's mouth in the first place. Separators are a plus. They are going in the right direction. But why in the world even put amalgams into a person's mouth? It doesn't make any sense to me. I know that, I've talked to some dentists who say, well, it costs more to put another kind of filling into a person's mouth and it may not be as durable as the amalgam, but nevertheless, you can do it. And for the additional cost, I think most people, if they are made aware that the amalgam is about half mercury, that they would opt not to have the mercury put into their bodies in the first place. And I just think there is an educational process that should take place in the dentist's office saying, the side effects of having mercury ingested into the human being either in the form of a vaccination or in the form of an amalgam. We were talking about the sludge that goes into the wastewater treatment system. Where does that sludge go when it leaves the treatment center? Mr. Walsh. About 20 percent of it nationwide is incinerated. Mr. Burton. Wait, let's stop right there. It is incinerated. Mr. Walsh. Correct. Mr. Burton. When it is incinerated, where do the particles go? Mr. Walsh. You mean the mercury? Mr. Burton. Well, anything that's incinerated, doesn't it go up in the air? Mr. Walsh. Some of it becomes ash. Some of the mercury is emitted. About 95 percent, 96 percent, I forget the exact figure, is captured in the pollution control device of the incinerator. Mr. Burton. OK, where does it go then? Mr. Walsh. I don't remember off the top of my head where it goes then. Mr. Burton. Well, it doesn't just disappear. Mr. Walsh. No, I assume it is disposed of. Mr. Burton. Is it recycled in some form into another mercury product? Mr. Walsh. I'm afraid I don't know what the---- Mr. Burton. But you know it does exist; it is there. Mr. Walsh. Oh, no question, it's an element. Mr. Burton. So the mercury is in the environment after it comes out of an amalgam and goes through the system, right? Mr. Walsh. Could you repeat the question? Mr. Burton. The mercury that's in the amalgam, when goes through the system, the sludge or whatever it is, it is back in the environment some place. Mr. Walsh. It is in the sludge, which is either landfilled, and we've looked at the studies that have been done historically on the emissions from landfills and looked at the percentage of mercury that would be from sludge; it is a very small amount, but---- Mr. Burton. Wait a minute. It says that 30 tons of mercury is going into the amalgams a year. That's the estimate. Mr. Walsh. Yes. Mr. Burton. Excuse me, 6 tons of mercury, excuse me, 6 tons of mercury is going into the amalgams per year. That 6 tons is going to go some place. It is either going to stay in a person's mouth or into the wastewater treatment system, and it is either going to be incinerated, in the sludge, or it is going to be sent someplace else, or it is going to be put into a landfill. If it is put into a landfill, it's going to leach down into the ground and into the groundwater. We've had tests of water in Indiana that's found mercury in the groundwater. Now, why in the world--I'm not talking about the separators now--why in the world wouldn't dentists or anybody that deals with mercury say, hey, it is a toxic substance, we ought to get it out of the environment in any way possible? And a dentist, knowing that they are working with it on a daily basis, why wouldn't they want to get it out of system? Mr. Walsh. Well, we looked at EPA's regulation, and these are long standing regulations from the 90's. They looked at all of those issues when they issued the regs. The National Academy of Science reviewed the biosolids limits, and the, I believe NACWA has said that all the evidence suggests that those metals, mercury included, are not causing health hazards when they are disposed of in compliance with those regs. Mr. Burton. Recently, the U.S. Food and Drug Administration settled a lawsuit with several consumer groups promising to classify dental amalgam and list the possible hazards involved with mercury-based fillings within a year. As part of the settlement, the FDA has even publicly withdrawn its claims that amalgam is safe for all and now warns--this is the FDA now-- dental amalgams contain mercury which may have neurotoxic effects on the nervous systems of developing children and fetuses. Why--does the American Dental Association agree with that warning? Mr. Walsh. Again, the purpose of my testimony and the focus is on the environmental impacts, and I am an attorney. I'm sure if you want to submit a question to the American Dental Association, they will provide an answer. But you're asking the wrong--you're just asking the wrong person. Mr. Burton. You don't have the answer to that. But the FDA has publicly withdrawn its claims that amalgam is safe for all and now dental warns dental amalgams contain mercury which may have neurotoxic effects on the nervous systems of developing children and fetuses. And that being the case, why would they put them in an adult's mouth in the first place, because obviously it could have an adverse impact on the adult as well? I just don't understand the ADA. I just do not understand it. When I had the amalgams put in any mouth, I can remember vividly, because I had some pretty bad teeth at one time, and I remember vividly them mixing it up and squirting it into my mouth. And I can remember, remember them sucking it out with a vacuum cleaner and it going down into the water system, going through the system. And when I'd spit it out, it was going into the water and down into the sewage system. And when I--and the part that went flushed out or vacuumed out went into my body. And I just can't understand why people don't realize that mercury is toxic, and it shouldn't be inserted into a human being in any form. And no matter how much you say--and I won't take any more time, Mr. Chairman--but no matter how much you say all the science and research---- Mr. Kucinich. The gentleman has another 2\1/2\ minutes actually. Mr. Burton. Thank you. No matter what is said by scientific research or anything else, common sense would dictate to me and to any human being that's made aware of the dangers of mercury that it shouldn't be in your mouth. They took it out of thermometers. They took it out of Merthiolate, Mercurochrome. They took it out of ophthalmologic liquids. They take it out most of the children's vaccinations. It is still in--it is in almost all of the adult vaccinations. And I just cannot understand, it just alludes me why a substance that is as toxic to the neuro--neuro system would be put into the human body. I just can't understand it. With that, Mr. Chairman, I don't--I have a sense of frustration that goes on every time we have one of these hearings. I will just yield back the balance of my time. Mr. Kucinich. I thank the gentleman. Congresswoman Watson you may proceed for 13 minutes. Ms. Watson. I just want to let Representative Burton know I am sitting here so frustrated. And I really want to know, Mr. Chairman, why the American Dental Association would send their attorney and not a health professional for this hearing. Since the counsel for the ADA is here, we ought to have someone from the opposing side, some attorney come, because I've been listening to the responses. And these are truly the responses from a defense attorney and not the responses from a health professional who is interested in the health of every single human being here in the United States. So I'm going to address my questions to you, Mr. Walsh. Does the ADA support local and State government efforts to reduce mercury? And how does it encourage its members to cooperate in these programs? I want to go further to say, you said many minutes ago that it should be a local and State, but Mr. Burton is from a different state; I'm from a different state, and Mr. Kucinich is from a different state. We ought to have some kind of Federal regulation because the risk is the same regardless. I'm from California, and the risk is high, and you keep talking about the surface water. I want to tell you about the water that is waste that apparently is not being processed, because I have evidence. And I'm sure, Mr. McCormick, when I direct some questions, knows that there is evidence showing that the mercury comes from the waste that comes from dental offices mainly. And I also understand that Mr. McCormick's report in some way has been curtailed when it was completed, but I will address this to him. So will you please deal with what the ADA is thinking in terms of local and government efforts to reduce mercury? And then if it encourages its members to cooperate in these programs? Would you please respond? Mr. Walsh. Well, the ADA has been supporting, since at least 2002, efforts to reduce the discharge of amalgam into wastewater treatment plants, initially through what was then the use of best management practices that were limited to chair-side traps. Ms. Watson. Period, period. These were voluntary efforts, yes, no? Mr. Walsh. The ADA best management practices are voluntary recommendations of the ADA. We have no---- Ms. Watson. OK, they are voluntary? Mr. Walsh. Yes. Ms. Watson. Thank you very much. Mr. Walsh. We also have worked cooperatively with regulatory agencies and various State agencies--State associations. Ms. Watson. OK, put a period there, because I'm going to use my time---- Mr. Walsh. Yes. Ms. Watson [continuing]. Very thoroughly and wisely. How does the ADA encourage its members to cooperate with these programs? And what is the percentage of cooperation, voluntary cooperation? Mr. Walsh. The answer to that, you need to understand---- Ms. Watson. Wait a minute. How does it encourage its members? Can you get right on point? Mr. Walsh. Well, they have developed their understanding. Dentists were not familiar with the regulatory system. They were being faced---- Ms. Watson. So you're talking about enlightenment---- Mr. Walsh. Well, first you have to educate anyone---- Ms. Watson. I am an educator so I like that response. Mr. Walsh. Whatever it is, whether it is an enforcement action or a voluntary program, first, you've got to inform the regulated community---- Ms. Watson. Good. Period on that, period, period, on that. Should we educate the patients as well when they walk through that door? Should we educate them about what the amalgam contains? Mr. Walsh. Again, that is not the subject of my testimony. Ms. Watson. Yes or no? Mr. Walsh. It's just not within my area of expertise. Ms. Watson. So you don't know. You don't know. You don't know if we should educate the patient? Mr. Walsh. I am---- Ms. Watson. You know, that's why I want a health professional here, not you the counsel, because you represent just one side of this. And you're going to give me the legal jargon, and that's not getting to the problem. I'm going to have my staff give you the bills that I have introduced, 7 years. And we're trying to get them moving because my interest, my interest personally is protecting the health of the public. That's my interest. My interest is letting them know the risk they undertake when they have--I'm passionate about this because it happened to me. And they would send you the counsel and not the health professional. OK, you didn't tell me what percentage of the dentists are cooperating. Do you know that? Do you know that? Mr. Walsh. There are no hard figures. EPA---- Ms. Watson. OK, you don't know it. Mr. Walsh [continuing]. Estimated---- Ms. Watson. Don't give me the jargon, please. My time is limited. You don't know it. You don't have those figures; yes, no? Mr. Walsh. There---- Ms. Watson. You don't have those figures---- Mr. Walsh. We do not have any figures, correct. Ms. Watson. Yes, no? Mr. Walsh. We do not have any figures, Ms. Watson. OK, thank you. What was the difference about the experience in EPA Region 8? And according to Mr. McCormick, you were strongly opposed to the EPA's guidance on setting and meeting local limits for toxic metal discharge. Mr. Walsh. We started voluntarily coming to EPA, over a year and a half before Mr. McCormick ever issued his guidance, seeking to put a voluntary program together to reduce the amount of amalgam. In the midst of that, we found out that the city of Laramie was being told that they would be enforced against if they didn't meet a number in a draft guidance. We asked to see the draft, so we could comment on it. Mr. McCormick mentioned a Region 5 draft. We had commented earlier in the year on a Region 5 draft, which in fact does not say ``use only voluntary.'' It says, ``you may use a voluntary; you may use a mandatory.'' And it says you can use what was then just chair-side traps and vacuum filters or you could require separators---- Ms. Watson. Period, period. Did you try to influence the outcome of the EPA policy in Region 8? Mr. Walsh. We filed public comments with Region 5, with Region 8, with EPA headquarters. We continue to fill comments in regulatory proceedings. Those comments are public record. Those comments have been given and are on the Internet. In fact, we file and attach all those comments. Ms. Watson. Let me read this. subcommittee staff spoke to the ADA and asked your representatives about the case. Jerry Bowman, the ADA's general counsel told my staffer or this staff of the committee that the ADA has no control over an EPA representative. However a letter written by Mr. Bowman to Benjamin Grumbles, the assistant administrator in February 2005, reveals that the ADA tried to interfere with Mr. McCormick's initiative. Now I'm going to give you a relevant quote from that letter: Region 8 has clearly not shifted its position one inch since our meeting with you. As we stated then, this is a very damaging position. Through its proposed guidance, Region 8 will wipe away EPA's effort to reach consensus to work with small businesses and to encourage voluntary efforts and replace those goals with a command and control strategy. Mr. Walsh, please help me understand this, the ADA supports the use of amalgam separators, and you conceded the environmental impact of dental mercury on the environment was great. So why was the ADA so strongly opposed to EPA's efforts in Region 8? Do other State or local governments who try to initiate similar policies have the same to look forward to from the ADA? Do you have any idea? You're representing them. You're the counsel. Mr. Walsh. These decisions are made on a case-by-case basis. The Michigan Dental Association is supporting, contrary to what was said earlier, a statute that would require amalgam separators in Michigan. What we were doing then, this was before the recent amendment to the BMPs that required amalgam separators, is we're taking the position that the local governments, the State and local entities should be free to choose a voluntary program or a mandatory program. What Mr. McCormick, and he is trying to fulfill his duties, he precluded any voluntary program. We believe, given the number of sources, given the nature of the sources, professional people who were not familiar with the environment, that the preferable way and the more effective way to use the limited resources that the agency has on enforcement is to use a voluntary program always backed up, and we would be remiss if we didn't tell our members that this they don't fulfilling voluntary program, if it is not effective, a mandatory program would follow. But this has been done---- Ms. Watson. OK, period, period, period, please. Mr. Walsh. Done by a number of---- Ms. Watson. Period, period, when I say that, please cease, because I'm on time. They are keeping time on me. Mr. Kucinich. The gentle lady has another minute. Mr. Walsh. I apologize. Ms. Watson. The ADA supported a lawsuit filed by Laramie dentists opposing the Region 8 guidance; is that correct? Mr. Walsh. No, that's not correct. We filed comments publicly and appeared at the council meeting, and we explained the reasons we thought a more cooperative voluntary approach was appropriate---- Ms. Watson. I got it, I got it. Mr. Walsh [continuing]. As was pointed out. Ms. Watson. Mr. McCormick, can you tell me about the--give me a summary of what your report showed for Region 8. Mr. McCormick. The strategy? Ms. Watson. Yes, and what your recommendations would be. Mr. McCormick. The chairman asked a really good question earlier. It was rhetorical, unfortunately, and deals with what exactly you're asking, is how far do you go with regulation? I kind of want to make it clear because everything seems to get spun here, and that's a frustration, when I was a regulator, that I always had. The law already exists, the Clean Water Act exists, and the regulation exists, and they clearly say, although the ADA probably wouldn't accept this, that we have a problem with the pollutant; it's mandatory to implement controls. It is not a voluntary reaction to a pollutant problem. The regulations already exist. They are black and white. There isn't a gray area there. And that's where--that's sadly where the influence is kind of coming in twisted. There is no leadership to make sure that these regulations are implemented and enforced. The regulations are there: If mercury is causing a problem, you must control it being discharged into a sanitary sewer system. There is no gray area in the regulations. That's what my strategy said. It said, like we do with every other pollutant that's causing a problem with an environmental criteria standard, you shall control discharges from nondomestic sources, which include dentists---- Ms. Watson. A question to the Chair, ``shall'' and ``may'' are two different legal terms. Mr. McCormick. Absolutely. Ms. Watson. ``Shall'' was used, making it mandatory, correct? Mr. McCormick. In the regulations, it's ``shall.'' Ms. Watson. The attorney is moving his head, because these are legal terms, ``shall'' and ``may.'' ``May'' is permissive; you do it if you want. ``Shall'' is mandatory. Mr. McCormick. I would just direct the ADA to the objective---- Ms. Watson. OK. I just asked my staff to get me the language. Mr. Walsh. You should also look at the Court of Appeals opinion---- Ms. Watson. Mr. Walsh, I was addressing---- Mr. Walsh. Oh, I'm sorry. Ms. Watson [continuing]. Mr. McCormick. Thank you. Mr. Walsh, are you a member of Pepper Hamilton, L.L.P. Mr. Walsh. Yes, I am. Ms. Watson. Is that your firm? OK, the lawsuit I believe was filed--I'm not sure of this date--December 17, 2004. Mr. Walsh. That's the date---- Ms. Watson. Somewhere in there. Mr. Walsh. That's the date we filed comments with the city. Ms. Watson. And you have--you wrote this letter, if I'm correct. This is the city of Laramie Public Works, you wrote it to the mayor and the city council member. Mr. Walsh. Correct. Ms. Watson. If there is anything I say, then you can intervene, and say, it is not correct or just not a factoid. Mr. Walsh. OK. Ms. Watson. And remember, you're sworn in, so that is why I say that disclaimer. You say: I have been retained by the Laramie Dental Association, which represents all 12 dentists in Laramie, WY, and the Wyoming Dental Association, and the American Dental Association to provide their comments on the city of Laramie's proposed local limit of two-millionths of an ounce of mercury per liter, that's 2 parts per billion, for wastewater discharged into the city of Laramie's sewage treatment plant. The ADA has also submitted comments on the EPA Region 8 draft guidance. That is the motivating force behind the enactment of this poorly--poorly--thought out ordinance and has met with the EPA assistant administration--administrator of water and his staff to address this draft document and as a part of its ongoing effort to develop a national guidance for reducing mercury releases from dental offices. And the Laramie dental community strongly opposes this specific ordinance. And then you go on to state the reasons. Is this letter authentic? Mr. Walsh. Yes. Ms. Watson. And you still believe those reasons that you state in your letter of December 17, 2004, are relevant to today? Mr. Walsh. Yes. Ms. Watson. OK. And you say there is no need to rush to judgment; the EPA guidance is still draft and is inconsistent with national policy. The intent and my intent is to change national policy. So I'm going to have your letter a matter of record, Mr. Chairman. Mr. Kucinich. Without objection the letter will be included in the record hearing. [The information referred to follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Ms. Watson. And I want you to look at my proposed legislation, and I want to you respond to me and to the other members of this subcommittee as to how my proposed legislation would be opposed by the ADA and why. Do I have your commitment to do that, to look at my legislation and tell me if it's inconsistent with this letter that you wrote opposing the draft coming from Region 8? Mr. Walsh. We will look at it and respond. Ms. Watson. And get back to me. Mr. Walsh. As positively as possible. Ms. Watson. If you would respond, which I would appreciate it, I'm going to look at your letter, and I will read your response. And I will share it with the subcommittee and the Chair. Mr. Kucinich. I thank the gentle lady. Without objection, the Chair is going to continue with one more 5-minute round of each of the witnesses or of this next-- of this panel. I would like to begin with a question for Mr. Walsh. I want to ask you a question about what you term as your voluntary success stories in the ADA's comments to the EPA concerning its dental office scoping study. You reference five examples of voluntary success stories in Massachusetts, Duluth, Washington, Madison--and Madison, WI, and the Minnesota Metropolitan Council for Environmental Services. We have looked at these carefully, and this is what we found: With the exception of the Minnesota case studies, all were a combination--a combination--of voluntary and mandatory provisions. Even the exception proves the rule. In Duluth, MN, there are only 55 dental offices, and the lead chemists in the Western Lake Superior Sanitary District obtained a grant for all the separators acquired. Moreover, the sanitary district had a very hands-on approach and worked with every office to install the separators. Even the sanitary district told us that this model could not be replicated in a larger city. Duluth, MN, has submitted testimony to be entered into our hearing record. If we have a slide ready, can staff put up slide 3? Do you have that available? OK, between--is that the right chart? We're looking at the slide that has to do with the Massachusetts Dental Society. I'm just going to--do you have it? OK. Yeah, that looks like the right one. Is that OK? Between 2001 and 2004, a memorandum of understanding between the Massachusetts Dental Society and the State, and by 2003, there was only a modest increase in the installation separators. In 2004, the Massachusetts Department of Environmental Protection initiated a followup program to speed up the process. It did two things. One, it offered incentives for voluntary compliance; and two, announced that mandatory regulations would be adopted in 2006. So that, by 2006, the compliance rate in Massachusetts was about 75 percent, and after the implementation of the mandatory program, compliance had jumped to 95 percent. Mr. Walsh, despite your testimony that deems Massachusetts a model for voluntary compliance, it should be noted that when it was strictly voluntary, between 2001 and 2004, it wasn't very successful at all. We also have testimony from Washington State; Madison, Wisconsin; and they tell a different story than the one that you've told. Like Massachusetts, their purely voluntary approach had no impact until there were incentives to install the separators and the government announced a looming mandatory program. In view of a full reading of the history of these case studies, wouldn't it be more accurate to describe these cases as models of government-dental collaboration as opposed to voluntary success stories? Mr. Walsh. I think my testimony, my opening statement, indicated that we had learned a lot in the dental community. We were talking about a problem that really wasn't on the horizon, certainly regulatorily, before 2001. And the dental community is 155,000 different people. They had to be educated as to the law. They had to be assured that, in fact, the separators--and they went out and did it themselves--could be tested, were effective, that we did surveys of the costs. I've mentioned a number of times the amendment of the best management practices last year to include separators; that-- dentistry makes many of the big decisions by vote of the House of Delegates. These are people elected by dentists geographically, and they vote. It was an overwhelming vote. There is no question that understanding and cooperation was not there initially, has grown over time. We believe that dentistry and the fact that we have a common goal now of 100 percent of all dentists should follow the best management practices, that this is still more like other examples. In 1999, EPA went to the laundries and said, there are so many little laundries, we want a voluntary program. It has been done with a number of different industries, including mercury in laundries; a lot of laundry detergents have mercury. The kind of---- Mr. Kucinich. But we are not drinking the dirty water out of the laundry. I just want to point something out to you, and that is that, you know, you're suggesting that dentists now install separators because they are better educated, which is, you know, good, obviously. I mean, you're also suggesting, we've learned; we're trying to move in the right direction; and here is what we're doing; and this is the progress that we're having voluntarily. But in your testimony, you write that voluntary programs are just as effective as a mandatory approach. But according to the subcommittee's national survey, that doesn't seem to be the case. Can we put that next slide up there? Now, if you look at these figures and understand them, it shows that voluntary programs don't exact the same results as mandatory ones. That's what the record suggests. Would you like to respond to that, Mr. Walsh? I mean, what are your thoughts about this? Your whole presence here is trying to defend voluntary as opposed to mandatory, but here we've got some actual survey data that seems to contradict. We're informed that we have an up-to-date slide. Do you want to get it up there? Have you got it now? I'll give Mr. Walsh a moment to take a look at it. Mr. Walsh, do you have--does the committee staff have a copy of this? Can you see that, Mr. Walsh? Mr. Walsh. The slide that's up on the screen? I can see it. Mr. Kucinich. The name of the State, county municipality offices with separators installed; voluntary separators installed; mandatory. Mr. Walsh. And the question is? Mr. Kucinich. Well, the question is, voluntary or mandatory? I mean, you're defending a voluntary approach, and it seems that the compliance level just isn't there. And if you are recommending these amalgam separators on a voluntary basis, but it doesn't appear to work, why wouldn't the ADA change its position and tell people they have to have them in there? Why wouldn't you do that? Mr. Walsh. Well, what I think we would be doing, and this, again, the BMPs, we added the separators last October. The separator pieces are being put into the education requirements. What we have now is the leadership overwhelming voting for separators. That didn't exist, and there is no question, when this first came up, they first asked how can we be regulated; we're dentists? There is an education process, information process. Dentists like science. We went out and did the science. Many of these things the ADA has done on, you know, its own expense to help set the pieces that would allow for putting in separators, and we are willing to do other things to keep track of the information rather than a lot of paperwork going around, keeping track of actually how much dentists send amalgam to either recyclers or the amalgam separator manufacturers so we have hard figures, rather than pieces of paper that say this is what is being done. Mr. Kucinich. I just have to say that anyone who is watching this, just I would assume, as the unbiased observers that are out there, it seems that the ADA has a resistance to mandatory regulations with respect to dental mercury. It seems that your resistance to it is almost theological. Faced with a tremendous amount of evidence, you just don't want to get off that position of saying it is voluntary instead of mandatory. I'm wondering--it seems to me, and I don't know how my colleagues feel about this, but in listening to Mr. Walsh, he's very well spoken and obviously a very effective witness from the ADA's standpoint, albeit that there are some concerns that there are questions you couldn't answer, and we are going to submit followup questions to the ADA to give them a chance to go on record. But are there product liability concerns here? Is there something deeper here that you're--that a class action could be in the offing if all of a sudden, you take this, you feel that it would be fortifying a position and would undermine your position? Did you ever have any discussions about that? Mr. Walsh. Well, that would be attorney-client if I had discussions. But frankly, our concern is, it has to do with the nature of, I think, dentistry and what we think is the more effective way; 100,000 different dental offices is larger than most point-source dischargers in the country. Mr. Kucinich. Indeed, I mean that's why this has some consequences. Mr. Walsh. It also makes it difficult to enforce. We think that whatever the final decisions of either Congress or the agency, there should be cooperation between the government and dentistry. I understand that one can say it should have been done quicker, but there is a process that the American Dental Association goes through in terms of getting the science behind things, getting educated. And because they elect their leadership and some of these discussions are made by the House of Delegates, it is done with deliberate process, and we are now at a stage that's different from when we were in these other things. I mentioned a few minutes ago, the Michigan Dental Association is supporting now a statute making separators mandatory. Each State differs. There are different circumstances, and we think---- Mr. Kucinich. I just want to say, this is very interesting, this assertion, because here we are, mandatory or voluntary, case-by-case basis, as if the science should be applied on a case-by-case basis. We either have scientific facts here that underlie the concerns that bring this subcommittee to this moment and health concerns, or it is just a case-by-case basis. You're an attorney. Surely, as an attorney, you are--bodies of law, it's understood, are--you know, the basis of them are not voluntary; they are mandatory. And when we're talking about regulation, the entire structure of regulation in this country is based on certain things you can't do. When Moses came down from the Mount, he didn't say, these are 10 voluntary ideas here, commandments; thou shalt not, thou shalt not pollute, perhaps. Or maybe, whether you like it or not, if you like to you could pollute, if you don't--this is where this whole meeting turns today. I would suggest to you respectfully as someone who has a great deal of admiration for the kind of effort that goes into a dental practice, into the life of a dentist, who understands the commitment that dentists have to their patients, the ADA, it seems to me, for whatever reason, whether it is product liability, class-action exposure, or what, the ADA is really behind the curve on this, and I don't understand why that is---- Ms. Watson. Mr. Chairman, would you yield for a question? Isn't the Hippocratic Oath that you do no harm? Mr. Kucinich. I'm not a doctor, but I know that to be so. Ms. Watson. Well, next time we hold a hearing like this, would you bring me someone from the association who is involved with taking that oath rather than an attorney who doesn't take that oath? Mr. Kucinich. Well, we asked--in fairness to Mr. Walsh, I mean, we asked the ADA. First, we invited the president. The president wasn't available. We agreed that Mr. Walsh would be an effective witness on the question of regulation. Now, I will give you that much. Ms. Watson. He is. Mr. Walsh. Thank you. Ms. Watson. But not being a health professional who---- Mr. Kucinich. But we have to set the ADA on record---- Ms. Watson. Thank you so much. Mr. Kucinich. To say that mercury contamination to wastewater is environmentally hazardous. We still don't have that out of you Mr. Walsh, but I think that--I think we'll somehow be able to establish that with or without you. Mr. Burton, your time. Mr. Burton. I won't take much time---- Mr. Kucinich. I just want to say, why else would they support separators if they don't believe that mercury contamination to wastewater is environmentally hazardous? Mr. Burton. I think, Mr. Chairman, a high school student studying science would know that mercury is not the sort of thing you would stick into a human being in any form. I mean, I don't think this is rocket science. I think anybody with any common sense knows that. And no matter how much you talk about it, mercury is a toxic substance, it shouldn't be injected into the human body in any form, period. It's just crazy. Now, I'm a conservative, and I don't believe in government regulation unless it is absolutely necessary. But when an organization doesn't voluntarily comply with something that's a public health hazard, dealing with public health hazards, then the government has no alternative than to do something about it. You know, in your testimony, you highlighted two programs to encourage dentists to voluntarily install separators as examples of why voluntary problems are better than mandates. The first program you talked about was by your ADA counterpart in 2003, involved dentists in Duluth, MN, where a voluntary program achieved a 100 percent remarkable compliance rate. Are you familiar with that? Mr. Walsh. I am, yes. Mr. Burton. Do you know that was paid for by the government, all those separators? Mr. Walsh. I know the dentists and the local POTW applied for a grant. Mr. Burton. But you didn't say that in your testimony. I mean, this was a voluntary program? I mean, the dentists didn't pay for any of it. It was paid for by the sewage treatment organization there. Mr. Walsh. The biggest cost of amalgam separators is not the purchase of the separator, but it is the recycling of all the amalgam. That cost is borne by---- Mr. Burton. In any event, when you say it was a voluntary program, it was not a voluntary program. They voluntarily let them put them in their offices, but they didn't pay for them. And so I think there is a little bit of misleading of the committee there. Let me just say that I don't understand why we don't have somebody from the ADA here who is on the Board of Governors, whatever it is. You are a competent attorney, obviously, but a lot of these questions we have had and a lot of these statements that we have had that we wanted to make today was to the ADA itself. I think it is unfortunate that we don't have somebody from the ADA here to testify. Do we have anybody? Hold up your hand if you are a member of the ADA here. I would just like to know. You are a member of the ADA. Anybody else? But you are on the other side. I mean, is there anybody here with the ADA--no, nobody except you. Do you practice dentistry? Mr. Walsh. No. Mr. Burton. I just wanted to check. Mr. Walsh. I was a research physicist. If that helps. Mr. Burton. You were a research physicist. Mr. Walsh. Before I became a lawyer. Mr. Burton. Really. Mr. Walsh. Went to work for EPA. Mr. Burton. Did you ever put an amalgam in somebody's mouth? Mr. Walsh. No. Mr. Burton. I didn't think so. I tell you what. We have three other witnesses here who might have some things they might like to say on my time. So if any of you have anything you would like to comment on--you have heard all this testimony and the questioning. Mr. Walsh has been pretty kind to sit there and take all the punishment we have been giving him today, so I admire you for that. But I would like to hear from the three of you. Dr. Fischer, go ahead. Dr. Fischer. I am a member of the ADA, and have been for many years. I think one of my big disappointments professionally over the years has been the lack of leadership from the ADA on this issue. It is been a quarter of a century or longer now since I have stopped using amalgam, not because of anything I learned at an ADA meeting, but the ADA has sort of gotten in the way of a lot of informed consent legislation, as Congresswoman Watson knows, in California. They are not really trying to be responsible stewards. If they are putting 40 tons or 30 tons, whatever figure you want to use, into people's mouths every year, and there is 1,000 tons out there in people's mouths, you know, the only way to fix this is to put an amalgam separator on everybody's bathroom toilet or else stop putting it in. Mr. Burton. Mr. Bender. Mr. Bender. Thank you. First, thanks for the opportunity. I would like to correct for the record a statement Mr. Walsh made. I don't believe that sewage sludge incinerators have any kind of pollution control equipment, so they certainly aren't capturing 95 percent of the mercury without any kind of capture. Mr. Burton. While you are talking about that, you might elaborate and tell us where all that mercury goes and how it is distributed in the environment. Mr. Bender. Sure, thank you. Once the mercury gets volatilized it goes into the atmosphere and some of it, a certain percentage of it, rains down or dried up in a position locally, some of it regionally, and some of it goes into this global pool. Part of the concern about any dental mercury that goes into the air is that it will methylate, and when it methylates, it will get into the fish, and we know that is a problem. So, you know, a big area that hasn't been discussed today, which is in my written report, has to do with the cremation and the other air sources. During my last testimony in the fall, I presented information that there was between 7 and 9 tons of mercury air emissions from dental mercury releases each year. And I believe that Chairman Kucinich wrote a letter to the EPA asking questions about that number compared to the EPA's number of something like 1.5 tons, and I don't know whether or not the EPA has ever responded. But, you know, again, in Washington there seems to be a great concern over air releases, and we have had this--rightly so--a major focus on coal-fired plants which are estimated to emit 48 tons a year. Well, here you have another sector out there that is maybe emitting 10 tons per year. So, again, the concern there has to do with the methylization of the mercury and it gets in the fish, and we all know about the tuna and all the rest. But there are many different places, and Dr. Fischer did a great job in his testimony of laying out all the different places, where mercury gets released into the environment, and if there is the--the U.S. dental sector is still using 30 tons per year, 60 million mercury filling placements each year in 10 years or however many years the life of those fillings, that mercury is going to get released into the environment, and it is a perpetual cycle. As much as you use the mercury, it is going to get released into the environment. One area that we focused on with State legislation is the manufacturers, and I have actually been thinking, in putting this report together the last few days, that maybe it is time to hear from the amalgam manufacturers, because there is about five or six of them in the United States, and I think most of them made both the mercury free so-called composites and the mercury fillings. So maybe we are--some of the focus we haven't had today is on all of these individuals dentists who are really trying to do the best job with misguided information, unfortunately, from the ADA, that we need to hear from these five amalgam manufacturers. Because their numbers don't--you know, they have to report by State law. We lost the Federal arm to be able to track this mercury- use category with the U.S. Bureau of Mines stopping this tracking mechanism in 1999. Mr. Burton. I just want to make sure I get a chance to hear from Mr. McCormick, too. Go ahead. Mr. Bender. Sure. But the other thing I wanted to mention is there is a sort of a difference between sort of a laissez faire like voluntary installation of amalgam separators and the facts on the record. And the facts are on the record, and I have it in my written testimony, in California in 2005 the CDA single-handedly--sole opponent of assembly bill 996--defeated the legislation. In Michigan, ADA lawyers, helping with the separator issue, told a colleague that they would not have to deal with the issue in 2011. In Montana, in the ADA's own newsletter they talk about their one-two knockout punch. So, essentially at this point-- and it goes on and on, Oregon, Philadelphia, where have you, that we can't move this issue any more on the State and local level because they made it their business to stop us. So at this point we are coming to you because this State strategy is not working for us any more. Mr. Burton. So the point you are making very vividly is that they have a concerted effort to block anything but a voluntary program and the voluntary program simply is not working? Mr. Bender. Absolutely. Thank you. Mr. Burton. Let me followup with just one thing that you said and then I will just yield the rest of my time to Mr. McCormick, and that is that I, like you, believe that most of the dentists, probably 99 percent of them, are very honorable people trying to do a job, just like the doctors. But they are getting their information from the ADA just like the doctors are getting theirs from the AMA. I have talked to doctors and dentists, and unless it is coming from the gospel, which is the ADA, they don't believe it. Mr. Bender. Right. Mr. Burton. When you talk to them, and I have talked to a number of them about mercury, they say, hey, that is scientific research and the ADA says that, and that is gospel. So until the ADA changes and starts giving them facts as we see them, I don't think they are ever going to accept that. It is not because they are not good people, it is just that is what they are getting. Mr. Bender. Well, the only other pressure point we had, Representative Burton, I was a party in the lawsuit against the FDA to classify mercury as a medical device, and that is where we are starting to see a chink in the armor where the FDA, as you quoted, from their new information on their Web site, is now saying, admitting it is a neurotoxin. So I think we can also push on the FDA. Thank you. Mr. Burton. Mr. McCormick. Mr. McCormick. Yes, I was 17 years--among my other job duties--I was a credentialed enforcement officer with the Agency. I worked a lot of criminal cases as well as civil cases, and I have been cross-examined by some of the best environmental attorneys out there. I am an expert on the pretreatment regulations that cities have to comply with and that part of the Clean Water Act. If you want to keep it out of the sewer, the regulations are in place. The ADA can disagree, but 40 C.F.R. 403.2 says here are the objectives of the pollution pretreatment program, and it very clearly establishes that you can't cause problems with surface waters or any other environmental criteria. You know, again, my frustration is all we have to do is say let's enforce the regulations. That is what Region 8 strategy said, said where there is a problem you have to control it, and this is what it says in the pretreatment regulations implementing the Clean Water Act. It is not a gray area. OK, I have been on the stand. I have been grilled on pretreatment regulations. I am very well aware of the preambles to them, so I guess that is all I have to say. The tools are there. Mr. Burton. In 40 C.F.R. What? Mr. McCormick. 403.2--it is the objectives of the general pretreatment regulations. The tools are there. The regulations are there. What I was trying to do was take a document and provide technical guidance to State and local governments that said, and it is guidance, OK, it is not even rules. It said, here is a good way of doing it. OK. Here is a way to approach reducing mercury discharges to a sanitary sewer system when you have a problem with mercury. Very simple. I mean, it was very clear, and the ADA doesn't disagree with that, that is exactly what they admit it says. Mr. Burton. OK. Mr. McCormick. But it is mandatory at that point. Mr. Burton. Thank you, Mr. McCormick. Thank you all. Mr. Chairman, I yield back to you. Mr. Kucinich. Will the gentlelady yield? Ms. Watson. Certainly, and would you also ask the question of Mr. McCormick why did WHO ban mercury in thermometers. I will yield. Mr. Kucinich. I am still wondering, Mr. Walsh, before we wrap up work on this panel, the ADA supports separation, right, of the amalgams? Mr. Walsh. Correct. Mr. Kucinich. Why? Mr. Walsh. We believe that the best environmental result is to recycle the amalgam---- Mr. Kucinich. You don't do it because it is about recycling, it is not about contamination to wastewater being environmentally hazardous? Mr. Walsh. Every study that has been done by NACWA, by EPA and our own studies show there is a contribution, but it is a very small, less than 1 percent contribution. We are willing to do our fair share. Mr. Kucinich. You then would agree that mercury contamination to wastewater is environmentally hazardous? You are just saying it is a question of the degree; is that right? Mr. Walsh. We have never attacked the water quality standard, which is a fish tissue number or the biosolids numbers. There are a number of plants across the country where the biosolids numbers are, in fact, on average, about 3, the limit is 57. And, in many places, the water quality standard is 50 parts per trillion and the level, for example in Laramie, is 8. And the fish levels are not exceeding 0.3. Even there we think the mercury ought to be recycled, because that is the best beneficial use. Mr. Kucinich. Is it environmentally hazardous? That is the bottom line. You basically say yes, but you are saying the degree to which the effluent exists from dental offices isn't significant, is that your testimony? Mr. Walsh. Yes. Mr. Kucinich. Why do you support recycling? Is it just because you are for recycling everything or because you think that mercury ought to be recycled? Mr. Walsh. We think mercury--well. Mr. Kucinich. Why? Mr. Walsh. The ADA hasn't taken a position on recycling in general. I personally think many more things ought to be recycled. But the mercury ought to be recycled because it is the way you can ensure that the mercury is reused. You don't have new mercury being created, and it doesn't--even the small amount of mercury that is incinerated or otherwise gets into the environment would be lessened. Mr. Kucinich. You know, I was struck by your candid admission that you are not a dentist, but you are a physicist. That is very interesting. When a piece of mercury metal is heated in air, it comes together with oxygen in the air, and then if it is weighed it is found to have a greater mass that the original piece of metal had. If, however, the mass of the oxygen of the air that combines with the metal is taken into consideration, it would be shown that the mass of the product is within the limits of accuracy of any one instrument equal to the sum of the masses of mercury and oxygen that combine. Are you familiar with that principle? Mr. Walsh. I am afraid, just the way---- Mr. Kucinich. As a physicist? Mr. Walsh. You just read something that is very complex. Mr. Kucinich. Are you familiar with the law of conservation matter? Mr. Walsh. Yes, I am. Mr. Kucinich. As a physicist. Mr. Walsh. Yes, I am. Mr. Kucinich. As a physicist, do you see any relationship between mercury deposits in land and air as a function of the law of conservation and matter, of matter? Mr. Walsh. All the studies I have seen show that the levels in the environment are related primarily to air emission levels. The Everglades study, the Metallica study, various other studies. It is emissions in an oxidized form that ends up creating the methylated mercury that is accumulating in fish. Mr. Kucinich. Does the law of conservation matter, or does it not say that during an ordinary chemical change there is no detectable increase or decrease in the quantity of matter? Mr. Walsh. Mercury is an element. It is the same amount no matter what happens---- Mr. Kucinich. So what happens to the mercury when it goes down the drain? Thank you. You are a physicist, and I am glad you showed up. This panel is appreciated, and dismissed. Mr. Kucinich. I will ask the individuals who are here from the second panel to come forward. Are there any physicists on this panel? Anybody? Do we have a physicist? Is there a physicist in the house? Let's get started. Well, since you are all standing. [Witnesses sworn.] Mr. Kucinich.

STATEMENTS OF PATRICIA MAGNUSON, INDUSTRIAL WASTE INVESTIGATOR, KING COUNTY, SEATTLE, WA; ANN FARRELL, DIRECTOR, ENGINEERING DEPARTMENT, CENTRAL CONTRA COSTA COUNTY SANITARY DISTRICT; DR. C. MARK SMITH, DEPUTY DIRECTOR AND CO-CHAIR, MASSACHUSETTS DEPARTMENT OF EPA, NEW ENGLAND GOVERNORS AND EASTERN CANADIAN PREMIERS TASK FORCE; AND OWEN BOYD, CEO, SOLMETEX STATEMENT OF PATRICIA MAGNUSON Ms. Magnuson. Mr. Chairman and members of the subcommittee, thanks for this opportunity to tell our story. King County operates the major wastewater treatment system for the metropolitan Seattle area, including two large treatment plants with average flows of over 200 million gallons per day. We discharge treated effluent in the Puget Sound, a sensitive marine waterway. One hundred percent of the residual solids from our treatment plants, known as biosolids, are reused beneficially in wheat and hop fields in Washington, on forest lands in the Cascade Mountains, and in a composted product available for landscaping. We control the source of contaminants into our system by means of our industrial waste pretreatment program and extensive work with small businesses and households. Most mercury that enters our system ends up in the biosolids, even though our marketability. Even though our biosolids currently meet all Federal and State regulations for mercury, our concerns for future marketability of these solids drives our efforts to continuously make them cleaner. And, also, the potential for stringent mercury limits in the future is also a concern. Under an agreement with the Seattle-King County Dental Society we conducted an extensive collaborative program from 1995 through 2000 to promote voluntary compliance. We encouraged purchase and installation of amalgam separator units, which showed they could meet our limit for mercury. And the results, after 6 years, were that 24 dental offices out of approximately 900 had installed the amalgam separators. In 2001, in consultation with the local dental society, we decided that the voluntary program had failed and notified the local dentists that they would be required to meet our local discharge limits of 0.2 milligrams per liter total mercury. Using our existing authority we gave them the choice of installing separators or applying for a permit and proving they meet our limits without a separator, and we gave them 2 years to meet compliance. During that time, we provided extensive outreach to the dental offices, including technical assistance site visits by staff from the Public Health Seattle-King County to every office in the county. Local dentists did not fight this requirement but rather sought practical information about purchasing the separators and got on with the task. After the compliance date, approximately 750 additional dental offices had installed the amalgam separator units with the remaining offices quickly following suit by the end of 2003. Since 2003, we continued to perform outreach to the dental community through letters and the dental office Web pages. Compliance rates are determined through ongoing compliance inspections and by monitoring the amount of mercury in the biosolids. In conclusion, the voluntary program did not result in a significant change in King County. When separators were mandated, compliance happened quickly, dramatically and with little resistance. Partially as a result of this initiative, mercury levels in King County biosolids have dropped by about 50 percent, and this represents about 75 pounds of mercury that are kept out of our biosolids each year. Then I am going to go to the attached slides, and the first one graphically demonstrates the number of amalgam separator units sold in our county during the voluntary phase from 1995 through 2000 and the 2-year transition period from 2001 to 2003, during which they were required to be in compliance. Slide 2, and this provides an interesting look at two different areas within King County that received technical assistance visits from the public health inspectors, and the chart on the left is the number of amalgam separator units installed within our source service area, which is only a portion of King County. And this is where our pretreatment regulations apply and compliance was mandatory. The chart on the right includes all other dentists in King County, and there are areas served by other sewer districts or on septic systems, and our regulations did not apply to those dentists. All dentists received the same visits and information packets by public health inspectors, but the dentists outside our service area didn't receive our mailing and were told it is not mandatory. Slide 3, that just presents the annual median concentration of mercury in our biosolids from 2000, the last year before we introduced our mandatory program, till now. And that shows about the 50 percent decline, and that remained there. Finally, I would like to close by saying that we were able to work with the local dental community and citizens of our county using existing regulations, and to develop a relatively low-cost method of achieving measurable reductions of mercury in our biosolids. Other communities have found different approaches that better met their particular needs, and local communities need to have the flexibility to address this issue in the manner that will work with them. [The prepared statement of Ms. Magnuson follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. Thank you very much. Ms. Farrell. STATEMENT OF ANN FARRELL Ms. Farrell. Good afternoon, Mr. Chairman, Ms. Watson and Mr. Burton. I am Ann Farrell, Director of Engineering for Contra Costa Sanitary District, a special discharge district in Martinez, California. We are responsible for the collection and treatment of wastewater for approximately 450,000 residents and more than 10,000 businesses in central Contra Costa County, which is directly east of Oakland and San Francisco. I appreciate this opportunity to discuss our successful program to require dentists in our service area to install amalgam separators and reduce the mercury entering the San Francisco Bay. The San Francisco Bay is impaired for mercury. As the development of the total maximum daily load of allowable mercury for the San Francisco Bay was occurring, it became clear to us in late 2003 that significant reductions in our mercury load to the bay would be required. We knew from previous studies that 50 percent of our influent mercury was coming to us from dental offices. We had tried in the past to implement mandatory programs, but the dental community had approached our elected board, and we did not obtain board support. This time we wanted to try a different approach and enlist the support and cooperation of the dental community so that we could be successful in implementing an amalgam separator program. We developed outreach materials, and we were basically trying to acquire informed consent, which was mentioned earlier. We wanted to document the changes in the regulatory climate and our potential regulatory risk, as well as our legal authority, to regulate the dental community. And we began meeting with the local and State dental societies. Once we began educating the societies themselves we received a great deal of cooperation from the Contra Costa Dental Society and the California Dental Association and particularly from Patricia Conley, Roseanne Harding and Theresa Pichay, who worked with us hand-in-hand throughout this process. In 2004, we began with a survey of the dental practices in our service area to obtain accurate inventory of the best management practices they were utilizing. The best management practices were voluntary, but the survey was required so that we could get accurate information. After analyzing the information we obtained, we observed that while many BMPs were being used, which accounted for basically general and good housekeeping, very few of the dentists had installed amalgam separators, less than 15 percent. During that time, as we monitored our influent mercury, we found that the mercury had stayed about the same. We continued our outreach efforts to the dental community and shared the results of our inventory. At each of our meetings, the majority of the dentists were very supportive. They acknowledged that it was relatively inexpensive for them to install the amalgam separator equipment, and they understood that it would significantly reduce their mercury discharge to the environment, but they further suggested that it could be a competitive disadvantage and that they--it was not likely they would make the investment unless a program that was mandatory was implemented. During this same time period we continued with the carrot, not the stick approach. We took the opportunity to recognize any dental practice that voluntarily installed an amalgam separator through our annual pollution prevention awards program. However, during this time, this recognition was only conferred upon 13 dentists of the approximately 300 to 400 dentists in our service area. Based on the continued series of meetings and discussions with the local and State associations, we determined that it was necessary to go back to our board and recommend a formal and mandatory dental amalgam program. At that time, because we had the endorsement of the local and State dental societies, our elected board adopted an enforcement program in April 2006. We then began the implementation of the program and the actual permitting of materials, and we continued to partner with the local and State dental societies. We allowed them to review the draft copies of our permits and provide input. The permit requires self-certification. In other words, the dentist certifies that he has installed an amalgam permit--an amalgam separator. We mailed the permits in three batches, and the compliance dates were staggered because we had learned from other municipalities and States that the dentists had been charged outrageous sums to comply with the deadlines by some of the plumbers. And so we wanted to give them plenty of time and stagger deadlines so that they could negotiate with their plumbers, with their amalgam separator suppliers and have reasonable costs. The mandatory permit and certification process was completed in about 10 months. After the final deadline of December 31, 2007, had passed, only a few dentists had not submitted the required forms. Today a total of 318 dental practices have been issued a BMP permit and 314 of them have submitted the required self-certification form, for a 98 percent compliance rate. But we also need to look at the effectiveness of the program with respect to the mercury and our influent, and I believe there is a slide that shows our influent, which you can't read, so I will explain it. And, actually, I wanted to point out an error in the slide. Where it says parts per million, it should actually be parts per billion. But what we found is that our influent mercury concentration was reduced by over 70 percent, from 0.27 parts per billion in 2002 to 0.08 parts per billion in 2008. That is an annual average. Then our effluent, which is the mercury going into the San Francisco Bay, was reduced by 50 percent from 0.029 parts per billion in 2002 to 0.0149 parts per billion for 2008. I also wanted to point out, if you have the written testimony, there were some discussions earlier about the removal through a treatment plant. Our treatment plant is somewhat unique in that we have incineration, and we have wet scrubbers. So the mercury is removed from the air and goes into the wet--basically the treatment plant influent. Because it is in the scrubber water it is dissolved. So it is more difficult to remove it because it is not a solid that settles out. So if you study the chart, you will see that we only actually got about 27 percent removal of mercury in 2002, and with our reduced numbers we have about 29 percent removal of mercury. So the claim that you can get 90 percent removal of mercury through a wastewater plant is completely dependent on how much mercury is in the solids, because the solids are what is removed. If you have a lot of dissolved mercury, which may occur if you have an incineration process, then the mercury removal through the treatment plant is much less, and therefore the value to the environment of the mandatory amalgam separator program is that much greater because we are removing the mercury upstream before it can come in, be volatilized, be captured in the scrubber water and go out into the bay. So, in summary, the staff and our board are very pleased with the cooperation we received from the dental community, and we feel it is a very successful program, and we are going to continue to monitor it each year, to meet them, make sure the maintenance is occurring. And I welcome any questions when we get to the question period. [The prepared statement of Ms. Farrell follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. Thank you very much, Ms. Farrell. Dr. Smith. STATEMENT OF DR. C. MARK SMITH Mr. Smith. Thank you, Chairman Kucinich, Mr. Burton, and Ms. Watson, for inviting me today to testify about our efforts in Massachusetts and in the New England region to reduce mercury from the dental sector. I would also like to thank you all for summarizing, excellently, most of what I am about to say, and bearing with me to say it again. As a scientist, a fisherman and a father of children who love to fish and occasionally eat fish, I have been very concerned about the effects of mercury on our environment and on our children's health. To address the problem, I have been working in the mercury field in policy and research for the past 15 years. As we have heard today, many reports have concluded, I think appropriately so, that the dental sector is a significant contributor of mercury releases to wastewater, accounting for 50 percent or more of the mercury found there. Mercury wastewater can be released to the environment through sludge incineration, through sludge reuse and from wastewater. I would also like to note that sewage sludge incinerators typically do not contain or have mercury specific control technologies, and a substantial fraction of the mercury will be remitted to the atmosphere. What is captured is typically captured by scrubbers, as Ms. Farrell mentioned, and then can be recirculated back to wastewater treatment plants, contributing to wastewater discharge releases as well. Mercury can also be released from sludge reuse. And in New England we estimate that about 12 percent of our air emissions are attributable to sewage and sludge incineration, which is a significant amount. Eleven States now, as well as numerous municipalities, have adopted mandatory programs requiring the use of amalgam separators. This is based on recent results from a survey of the States conducted by the Quicksilver Caucus. In New England, mercury from the dental sector is being addressed through the New England Governors and Eastern Canadian Premiers Mercury Action Plan, which was adopted in 1998 and set a long-term goal of virtually eliminating anthropogenic sources of mercury in our region. We also adopted long-term goals of 50 percent reduction by 2003 and 75 percent by 2010. We have met and exceeded the plan's first goal, and we are well on the way to the 2010 target. We have done that by adopting State regulations that exceed EPA requirements in essentially all areas, focused on trash incinerators, coal- fired power plants, mercury products and also the dental sector. I would also like to note that we recently completed a regional total maximum daily load assessment for mercury, indicating that mercury inputs to our water bodies will need to be reduced by 98 percent to restore those water bodies to a fishable condition where the fish will be safe to eat. Yes, 98 percent is pretty high. In order to get there, you have to address all the sources, even ones that you might traditionally think are not significant. As I mentioned before, just looking at sewage sludge incineration emissions and the dental contribution to that, that is a source that we really do need to address in order to get our fish back to a situation where they will be edible. In 2005, we specifically adopted goals for amalgam separator use under our regional action plan. These goals were that 75 percent of dentists in our entire New England region would have amalgam separators installed by 2007 and 95 percent by 2010. In order to get there, all New England States have now adopted requirements for amalgam separators, and we currently estimate that over 91 percent of dentists who generate amalgam wastewater in New England are now using these pollution controls, reducing mercury entering the region's sewage by many hundreds of pounds each year and, of course, reducing emission from incinerators and the reuse of the sludge where the mercury concentrates. In Massachusetts, State regulatory agencies and the dental society of--Massachusetts Dental Society, signed a memorandum of understanding in 2001 to increase the voluntary use of amalgam separators in best management practices. Under this agreement, we did substantial outreach to dentists to educate them and had discount pricing on select amalgam separators. Although the MOU certainly helped to raise awareness, by 2003 we only saw a modest increase in the sales of separators in our State. In 2004, Mass DEP, my agency, implemented a followup program to speed up the process. At the start of this initiative we announced that we would be adopting regulations in 2006 which would require the installation of amalgam separators to achieve faster reductions, because it typically takes us about that 2-year period to develop and implement new regulations. We instituted an incentive-based voluntary early compliance program. Dentists participating in this program were required to certify that they used an approved amalgam separator, followed best management practices and recycled all of their waste mercury. As an incentive, the participants in the first year were exempted from permit fees, saving them a few hundred dollars, and the installed units were grandfathered into 2010. Our local Massachusetts dental society was very helpful in getting the word out about this program, and 75 percent of our dentists participated in that early compliance program with the backdrop of the mandatory regulations coming down the road. Regulations requiring separators were adopted in 2006 pretty much on schedule. To date, over 98 percent of facilities that were randomly expected have been found to have appropriate amalgam separators installed. Despite some compliance issues that we found in our audits relating to record keeping and recycling, our initiative has been very successful, and over the 2-year period of 2004 to 2006, when amalgam separator use increased to 75 percent in our State, mercury levels in sludge from the greater Boston area decreased by close to 50 percent. In conclusion, without appropriate pollution controls, the dental sector can be a significant source of mercury pollution to the environment. Amalgam separators can substantially reduce these releases. The successful experiences in Massachusetts and other States in reducing pollution from the dental sector will only support further national action in this area. Programs that include outreach through collaboration with State dental societies and that also include quantifiable goals and mandatory deadlines for the use of amalgam separators and other best management practices are both effective and achievable. Again, I would like to thank you all for the opportunity to testify today, and I am willing to answer any questions that you may have. Thank you. [The prepared statement of Mr. Smith follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. Thank you, Dr. Smith. Mr. Boyd. STATEMENT OF OWEN BOYD Mr. Boyd. Good afternoon, Mr. Chairman, Ms. Watson, Mr. Burton. I am Owen Boyd, founder of Solmetex. We founded Solmetex on the principle that we wanted to increase efficiencies in water technologies that were being deployed within the United States. So we took efficiencies that were being used in biopharmaceutical separations; namely, called advanced affinity chromatography, and we were able to migrate it into, at first, a resin that would remove mercury from water. We put systems into hospitals, we treat incinerator wet scrubber waste to remove mercury down to below a part per billion in water discharges. We do commercial installations to keep mercury out of wastewater. And we were asked to approach the dental industry to see if we could take mercury out of dental waste. After examining the profile of dental waste, we developed an amalgam separator. We call them amalgam separators because, in any other industry, they would have been called simply a filtration device. Most amalgam separators use, you know, one of four principles of filtration, which is centrifugal, mechanical, chemical or sedimentation. All of them have been used for well over a century. There is nothing novel about an amalgam separator. It shouldn't be viewed as a new technology. It is a simple filtration device held at point of source generation. We developed the device to make sure that we could not only take the mercury out but recycle the mercury so it didn't end up back in a landfill and just be a transfer waste. I am going to cover three areas. One is do amalgam separators work, do they have an impact on a sewage treatment plant, the cost and use of amalgam separators and a little bit of our sales history to show the impact of a regulation versus a voluntary approach. As I said, amalgam separators are filtration devices that have been used in a lot of dental clinics. In the European Union they have been used for well over a decade. The Paris Commission, PARCOM, in their Recommendation 93/2, they cited information received from Belgium, Finland, France, Germany, Iceland, Netherlands, Norway, Spain, Sweden, Switzerland and the U.K. That now will have mandatory regulations that the discharge of dental amalgam in the municipal systems has been significantly reduced by the use of separation equipment in recent years, in most cases by at least 95 percent. In Toronto, Ontario, the fifth largest city in North America, a 58 percent reduction of mercury in biosolids was recognized when an estimated 73 percent of dental clinics had complied with separator regulations. Their biosolid mercury concentrations were reduced from 17 kilograms a month, or 37 pounds, to 7 kilograms a month. Additionally, a 13 percent reduction of mercury in their final wastewater was measured. Minnesota, two particular POTWs; that is, a publicly owned treatment work or sewage treatment plant, Hastings and Cottage Grove, their mercury in biosolids were reduced 24 and 49 percent. U.S. Navy had 53 notices of violations from regulatory folks. That is now down to 3, 52 percent decrease in POTW biosolids. Duluth, MN, has had the same type of experience. Seattle- King County, they have reduced their amount from 74 pounds per year in 2000 to 38 pounds in 2004. The Strategic Envirotech Partnership from the Executive Office of Environmental Affairs in Boston, MA, tested amalgam separators in dental settings, and they measured 99.85 percent, 98.94 percent and 99.74 percent reduction in the three amalgam separator sites that they tested. The cost of an amalgam separator. There is a lot of different, varying costs, I can tell you. With about 120,000 clinics that deal with amalgam, our cost of $750 per system, that would run about $90 million to install at all of those clinics, and it would cost an additional $34 to $34.5 million a year to maintain those systems so they continue to be operational. That would be the cost of the removal at all dental clinics across the United States. If you can bring up slide 1 for me, these are actual numbers, and what that shows you is our units sold in what we refer to as States with regulations, States with partial regulations, and States with no regulations whatsoever. Partial regulations, these are States, you know, like California, where you have individuals POTWs or cities that take action, but not the whole State is regulated, and there were a number of States that do that, and it is in my written testimony. But you can see that, you know, what this chart shows you is that the States with the legislation, our sales are sky high. Those without, which are the yellow bars, are essentially unaffected. Those with partial regulations, we had very good results. As a matter of fact, if you looked at the results in total, that would show you that within the United States we have 93 percent of our sales are in regulated or nonregulated or partially regulated States. If you took all of our sales internationally and domestic, 99 percent of our sales are in regulated areas or partially regulated areas. If you look at the next slide, this will give you an impact, because we track our sales month-by-month in every area that is regulated. And what you can see is that the left side of that scale, that is a percent of sales, you can see that as a regulation comes into effect, the first 24 months we see very little activity. As the deadline approaches, you can see, literally, between 8 to 2 months before the deadline, the majority of our sales occur. You can also see--if you notice on the blue line, that is where you can give a lot of credit to the Massachusetts Dental Society for putting extraordinary effort into a voluntary approach. And we tracked that 24 months as a period of voluntary approach with a threat of regulated approach, but they got an awful lot accomplished in a short period of time. But what all that data shows you, in summary, first off amalgam separators do, in fact, work, if maintained properly. You can see the impact on regulations. If there were no regulations in the United States, we wouldn't be marketing here, we would be marketing elsewhere. And the cost for Solmetex systems is about $120 million to acquire the equipment and another $34.5 million to maintain that equipment. That number is not an estimate, it is reality, because we keep track of how many replacement cylinders are sent to each dentist every year, and the average is they change a little less than one replacement filter per year. I am going to go back to that graph just for 1 second. There is an interesting little note on followup. The yellow line you will see after the regulation, the deadline date, you will see another bump in sales. That bump in sales actually correlates to a letter that the Connecticut DEP wrote to dentists after regulations had passed. They had an indication that a lot of dentists had not complied. So they asked for a serial number, manufacturer number, installation date and the installer. And we saw another bump in sales as the enforcement arm of the regulation took place. Thank you. [The prepared statement of Mr. Boyd follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT] Mr. Kucinich. I thank all the witnesses. I would like to begin with a 5-minute round of questioning, begin with Ms. Magnuson. As an alternative to installing separators, King County could have chosen to treat its wastewater mercury. Why did you decide against that option instead of treating it and installing the separators? Ms. Magnuson. Instead of treating it at the treatment plant? Mr. Kucinich. Yes, yes. Ms. Magnuson. I don't think--it is costly to treat it at the treatment plant. Is that the question? Mr. Kucinich. Yes, you had a choice. Why did you do the one instead of the other? Ms. Magnuson. We had the choice? No, actually, King County--our treatment plant effluent limits and even the biosolids mercury levels were within our limits for our MPDS permit. Mr. Kucinich. What about the cost of treating it at the treatment plant? Is there a cost involved there? Is it a high cost? Ms. Magnuson. If the technology, yes, is there, it is a high cost. I don't have the costs for treating it at the treatment plant right now. NACWA did some studies, so I don't-- -- Mr. Kucinich. Do you have any information about the cost as far as the breakdown? Ms. Magnuson. For the treatment plant, to treat it at the treatment plant? Mr. Kucinich. Yes. You said it would be prohibitive? Ms. Magnuson. It is prohibitive, and it runs in the millions of dollars, like tens of millions of dollars, if it exists, you know, if the technology would be viable. Mr. Kucinich. So you are saying then that the separators are preferred to trying to---- Ms. Magnuson. Treating it at the source. Any of the pretreatment for metals, it is always preferable to treat it at the source. Mr. Kucinich. Ms. Farrell, I understand the first time you considered installing separators in dental offices you experienced strong resistance. What was different about your second attempt and what can you recommend to other counties considering policies to reduce dental mercury emissions? Ms. Farrell. Well, the first time we just kind of rolled out the program, and we didn't go work--do the prework with the dental societies. And so they immediately came to our board meeting and complained to our board, who is an elected board, and that was kind of the end of that. So the second time we got a little bit smarter, and we approached them. I think, also, times had changed where they were beginning to understand that this was coming down the road. We had a real regulatory requirement that we were going to have to meet that was going to cost us in the tens of millions of dollars, so we basically need to educate them that this was the least expensive way to meet our requirements for the community at large. Mr. Kucinich. Thank you. During your outreach meetings to dentists, you have said that dentists actually requested that the central Contra Costa County make separators a mandatory policy. Why was that? Ms. Farrell. I am not sure I said they requested. I think they acknowledged that it was unlikely we would get a high rate of participation without a mandatory program. Mr. Kucinich. Thank you. Dr. Smith, do you think it is accurate to describe the Massachusetts program as a voluntary one? Why or why not? Mr. Smith. I would say that the overall program was not strictly a voluntary program. Mr. Kucinich. Meaning what? Mr. Smith. Meaning the voluntary component was really applicable only to the incentivized early compliance part of our program, which was backstopped with a mandatory regulation. Mr. Kucinich. Did you offer incentives? What incentives did you offer to dentists who voluntarily installed separators before the program became mandatory? Mr. Smith. The two incentives that we offered, one was that we waived the permit fee so they did not have to pay permit fees if they came in early in the process. And the second incentive was that the units they installed were grandfathered. And in the voluntary compliance program, that early compliance component, we only required separators to achieve a 95 percent removal efficiency. The regulation specifies 98 percent, so it is modeled on regulatory certainty. Mr. Kucinich. So based on your experience, have you or would you recommend other States offer similar incentives? Mr. Smith. Yes, I think the incentives worked extremely well and were highly supported by the Massachusetts Dental Society. I think it really galvanized attention to dentists who really wanted to do the right thing, who realize that they needed or should be putting on the amalgam separators. And here is the shot in the arm to actually get them to take the step to do it. Mr. Kucinich. So you have established that a beneficial effect can be made on the environment if every dentist installed a mercury separator; do you believe that? Mr. Smith. Yes, absolutely. Mr. Kucinich. What have been the costs in terms of time and money associated with maintaining the dental mercury program? Mr. Smith. For the State? Mr. Kucinich. Yes. Mr. Smith. We haven't broken it down that way, but in order to minimize the expense in terms of staff resources to the Agency, and also to make it easy for the dentists to basically submit, we have been using a self-certification process. And we developed an electronic e-form that the dentist can basically fill out and submit to the Agency, which makes it very easy once the form was developed. Getting the form developed was difficult. So the cost to the Agency has been relatively modest. Mr. Kucinich. I would just like to say that the staff will submit some questions so that we can better quantify this as we prepare our report on this committee. Mr. Smith. If I could just add one more thing because it was brought up earlier. Mr. Kucinich. Sure. Mr. Smith. On the compliance and enforcement end, you don't have to go visit every single dentist to verify compliance and enforcement. We are using statistically based sampling to do that, which really minimizes the expense and gives you good data. Mr. Kucinich. That is noteworthy. I appreciate that. Thank you. Mr. Burton. Mr. Burton. Thank you, Mr. Chairman. Dr. Smith, you said that the amount of mercury in the fish up there really hasn't improved all that much. Mr. Smith. We actually have been seeing some improvements over the past--well, since 2000 to 2007, mercury levels in fish in Massachusetts have decreased by approximately 20 percent, depending on where you look. Mr. Burton. Are you eating fish up there that comes out of that area? Mr. Smith. Some of the fish are edible, are safe to eat. Many of them are still not safe to eat. I think we have a long way to go before they are. Mr. Burton. How do you decide when you go to the supermarket which fish to buy? Mr. Smith. Well, the smaller fish. Stay away from the tuna, the swordfish. Stick to the cod, the flounder and fish like that. Farm-raised salmon tend to have lower levels. Mr. Burton. Isn't that a heck of a thing you have to go through? Mr. Smith. It is. Mr. Burton. I don't eat much meat. I eat fish and chicken. It just bugs me to death to think that there is a lot of mercury in there. Mr. Smith. Yes. Mr. Burton. Ms. Farrell, without the separators the percent of mercury remains fairly consistent; is that correct? Ms. Farrell. That is correct. We saw very little reduction until we had the mandatory program. Mr. Burton. And, Mr. Boyd, you said that in Europe the compliance was almost 100 percent because it was mandatory; is that right? Mr. Boyd. That is correct. Mr. Burton. So I deduce from all of your testimony what the lawyer for the ADA was saying wasn't quite correct in that he thought that the voluntary program was going to be effective. I mean, all of you can answer once, if you want to. You don't think the voluntary programs work that well? Mr. Smith. I would say there is no good evidence that would support that. Mr. Burton. Well, there you go. As Ronald Reagan would say, there you go. I just wish they were still here so they could hear your testimony. I am sorry, but I think they already know it. It is just a matter of making sure that the message gets through to them. I know you don't have anything to do with this, but I just wish you guys didn't have to worry about this. I wish we weren't putting amalgams in people's mouths in the first place. But anyhow I really appreciate your testimony. Mr. Chairman, again, I want to thank you for having this hearing. I yield back. Mr. Kucinich. I thank the gentleman. The Chair recognizes Ms. Watson from California. Ms. Watson. I want to thank all of our witnesses for providing us with the empirical evidence, and I will join with my colleague and say I wish the attorney were still here. You know, we sit through a lot of these hearings, and these attorneys come in and they tend to get you all tied up in legalese so that we miss the point. Thank you for coming and giving us the specific evidence from what you are doing in your respective locations. I want to thank Dr. Smith in particular. I found your information to be very helpful. And Mr. Boyd, you have had some experience from the commercial, retail end. So I would like to have you tell about one experience where you provided free separators to dental offices, dental offices in Highland Ranch, Colorado, to encourage them to install separators in their clinics, and what was the outcome from this pilot project. Do you remember that one? Mr. Boyd. Yes, that pilot project was actually an opportunity for us to put in a very scientific setting the impact of an amalgam separator. It is unusual to have an opportunity to treat just the mercury influent with no other mercury initiative going on and measure quantitatively the reduction of mercury and solids and the production of mercury in their liquid wastes as well. So we, in a voluntary effort with the local sewer district out there, have provided free separators and we are doing free analyticals as well, which are being backed up by the local agency. The results aren't all in yet. It is probably going to be about another 6 months before we have definitive results. We had a similar opportunity in the city of Toronto, where there were no initiatives, but I can't say the science that was behind it was rock solid that showed that the impact of amalgam separators up there was incredibly dramatic. And, rather than argue the point, you know, we sort of go about it in a very scientific fashion saying we will provide the data. Ms. Watson. Thank you. In light of the information reflected in your second graph regarding the deadline dates, what kind of deadline would you recommend to State and local governments considering mandating the use of separators in their State, city or counties? Mr. Boyd. The experience that we've had is that a, you know, a mandated regulation, again, you will have some plumbers that if you give them a 3- or 4-month mandate, you know, plumbers will wreak havoc on the dental community. However, even with a 2-year, we have found most of the dentists buy in 4 months before the deadline anyway and set their own trap. So, you know, somewhere in between is probably the proper timeframe. Ms. Watson. Very good. Thank you. And can you tell us about your previous experience, specifically in Maine, and what was significant about your participation, and what was the result of the Maine hearings that you had? Mr. Boyd. Well, in Maine, I probably found myself in a very unusual situation in that I was testifying for folks that wanted amalgam separators and for the Maine Dental Association simultaneously. And what we were trying to do was to provide reality, because a lot of the regulation was being passed with what is called an ISO standard of performance, which is a static test run by an international--under an international standards organization protocol that determines the efficiency of a unit in that static test. And the efficiency of that unit, if you looked at the volume of mercury that you have to remove, whether something is 95 percent or 99 percent efficient, those efficiency numbers are almost invalid in terms of making much of a difference. The standard says you have to meet a 95 percent criteria, and my argument to the folks that wanted amalgam separators was, stay at 95 percent; if you go to 99, you'll limit the market choices the dental community will have, and then people like me could take advantage. So I argued against my own company's separators on that particular regard and argued for the Maine Dental Association that the 95 percent number would get the folks that wanted mercury reduction, it would get them the same equivalent reduction because the static test was not that representative of what actually occurred in a dental setting. So whether it was 95 or 99 percent statically, you know, when those systems are put into actual use, they still run about 98, 98 to 99 percent efficient. Ms. Watson. And I will just close with this. Mr. Chairman, you have been very kind to give us this time. As we try to look nationally and make policy, I would like you to take a look from the retail commercial end at my proposed measure, and we'll get you a copy, and suggest what policymakers should really do. I'd like Dr. Smith to do the same thing, and maybe all four of you, you know, what we should set as a national policy. You heard the attorney before, and rather than go down the wrong path because we're not considering both ends of this, I would like to get some feedback from you who have put what we're trying to do in practicality as pilot projects how we as a Federal Government can design the policy so it will be effective. Mr. Boyd. It would be my pleasure. Ms. Watson. Thank you very much. And, thank you, Mr. Chairman. And thank you, Mr. Burton. Mr. Kucinich. I thank the gentle lady from California. This has been a hearing of the Domestic Policy Subcommittee of the Oversight and Government Reform Committee. The title of today's hearing has been, ``Assessing State and Local Regulations to Reduce Dental Mercury Emissions.'' We have had a distinguished group of people here to testify. Panelists have included Michael Bender, the director of the Mercury Policy Project; Dr. Richard Fischer, the former president of the International Academy of Oral Medicine and Toxicology, Dr. Fischer is a dentist; Mr. Curt McCormick, former administrator, EPA Region 8; Mr. William Walsh of counsel to the American Dental Association. Our second panel, we've had Ms. Patricia Magnuson, the Industrial Waste investigator, King County, Seattle, WA; and Ms. Ann Farrell, the director of the engineering department Central Contra Costa County Sanitary District; Dr. C. Mark Smith, the deputy director and cochair of the Massachusetts Department of EPA and New England Governors and Eastern Canadian Premiers Task Force; and Mr. Owen Boyd, CEO of Solmetex. I want to thank these witnesses. I want to thank my colleagues, Representative Burton and Representative Watson, for their participation in this hearing which has taken over 3 hours, and members of our staff, who have well prepared us for this hearing. This subcommittee will continue its look at the implications of mercury as an environmental contaminant, the health effects of it, whatever the point source happens to be of that. I want to, again, thank everyone for their attendance, and this committee stands adjourned. Thank you. [Whereupon, at 5:44 p.m., the subcommittee was adjourned.] [Additional information submitted for the hearing record follows:] [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
