Why is MTBE so objectionable? THE MTBE PROBLEM Unlike other components of gasoline, MTBE does not biodegrade. MTBE is difficult and expensive to get out of the water. It costs around $1 million to clean up one well in California and $5 million to clean up a reservoir. MTBE has a bad taste and odor. MTBE travels quickly through soil and gravel. Lake Tahoe officials have told me that "out-of-control" MTBE plumes move one to nine feet per day, where it is now 1,000 feet from the lake. Where does it come from? MTBE comes from gasoline from leaking underground storage tanks, from pipelines, from motorboat engine discharges and exhausts, from spills and leaks at gasoline stations, from automobile accidents, from stormwater runoff and sometimes from sources unknown. A June 13, 1997 Oakland Tribune article reported that MTBE levels in the air around the San Francisco Bay area "have risen dramatically," quoting Bay Area Air Quality Management officials who said that MTBE detections in the air grew after MTBE was introduced in gasoline in the area. More recently (March 9, 1999), the Reno (NV) Gazette-Journal reported, "Traces of methyl tertiary butyl ether were discovered last week in air samples taken by the South Tahoe Public Utility District." A South Lake Tahoe official on February 5 told the Sacramento Bee that MTBE traveled through the sewer system, through the treatment system, through the export pipeline, across a stream and now into a reservoir 30 miles away. It is time to end it. GOVERNOR DAVIS HAS ACTED California Governor Gray Davis on March 26 issued executive order D-5-99 taking 11 steps to stop MTBE contamination, which Secretary Winston Hickox will describe for you later this morning. Governor Davis's actions included the following: (1) a phaseout of MTBE use in gasoline by December 31, 2002; (2) a request to U.S. EPA for a waiver for California's cleaner-burning gasoline from the federal requirement of oxygen in reformulated gasoline; (3) support for legislation to allow U.S. EPA to waive the federal oxygenate requirement; (4) labeling of gasoline pumps, indicating that gasoline contains MTBE; (5) new guidelines for cleaning up MTBE contaminated areas; (6) an evaluation, by December 31, 1999, of ethanol transport in air and water; and (7) a report on the potential for development of a California waste-based or other biomass ethanol industry. STUDIES RAISE SERIOUS QUESTIONS Several authoritative studies have raised questions about MTBE in drinking water. University of California A distinguished group of University of California scientists in November 1998 in a five-volume study recommended that MTBE be phased out over several years and that refiners be given flexibility in gasoline formulations to achieve air quality. Importantly, UC found that "there is no significant additional air quality benefit to the use of oxygenates such as MTBE in reformulated gasoline, relative to" California's reformulated gasoline formula. UC also found that "there are significant risks and costs associated with water contamination due to the use of MTBE." Lawrence Livermore National Laboratory A June 1, 1998, Lawrence Livermore National Laboratory study reached five important conclusions: 1. "MTBE is a frequent and widespread contaminant in shallow groundwater throughout California. There are presently 32,409 leaking underground fuel tank sites recognized in the state, 13,278 at which hydrocarbons are known to have impacted groundwater. A minimum estimate of the number of NME-impacted sites in California is greater than 10,000." 2. "MTBE plumes are more mobile than BTEX (benzene, toluene, ethylbenzene, and xylenes) plumes." Thus, it moves quickly to infiltrate groundwater. 3. "The primary attenuation mechanism for MTBE is dispersion." 4. "MTBE has the potential to impact regional groundwater resources and may present a cumulative contamination hazard." Association of California Water Agencies The Association of California Water Agencies has detected MTBE in shallow groundwater at over 10,000 sites in California. Some deeper drinking water wells have also been affected. ACWA's December 1998 study also documented MTBE contamination in many of the state's surface water reservoirs, concluding that motorized recreation is the biggest contributor of MTBE contamination and confirming other studies findings that MTBE tends to stay in the uppermost portion of the reservoir. A sampling dated April 22, 1999 detected MTBE in 44 groundwater sources and 28 surface water sources in California. MTBE IS NOT NECESSARY California can meet federal clean air standards by using our state gasoline regulations, which Mr. Hickox can thoroughly discuss with you. California's reformulated gasoline rules provide about twice the air quality benefits of federal reformulated gasoline. California has the cleanest gasoline in the world. Clean gasoline without MTBE can be and is being manufactured by several refiners, including Chevron Products Company, who wrote me on September 11, 1998, "We believe it is possible to replace gasoline, which currently contains MTBE with a combination of ethanol-blended gasoline and non-oxygenated gasolines, while maintaining the clean air benefits that the California Cleaner Burning Gasoline program has provided." A POSSIBLE HEALTH HAZARD U.S. EPA has indicated that "MTBE is an animal carcinogen and has a human carcinogenic hazard potential." The University of California study clearly concluded that we need more research to fully understand the human health impacts of MTBE, when the UC study called for a phaseout. Dr. John Froines, a University of California scientist, testified at a state hearing on February 23, 1999, as follows on their work: We in our report have concluded that cancer evidence in animals is relevant to humans. There are acute effects in occupationally-exposed workers, including headaches, dizziness, nausea, eye and respiratory irritation, vomiting, sensation of spaciness or disorientation and burning of the nose and throat. MTBE exposure was associated with excess cancers in rats and mice, therefore, multi-species. He cited "multiple, endpoints, lymphoma, leukemia, testicular cancer, liver and kidney." All four of the tumor sites observed in animals may be predictive of human cancer risk... The related question is whether there is evidence which demonstrates the animal cancers are not relevant to humans. The answer developed in detail in our report is no. There is no convincing evidence that the data is specific to animals. That is our conclusion. Nobody has come forward to tell us a basis to change that point of view. Many authorities believe that the human health effects of MTBE were not adequately known or considered when Congress last amended the Clear Air Act in 1990. MTBE IS SPREADING TO OTHER STATES While there is no comprehensive survey available, we do have some data to show that MTBE is contaminating the water in other states. A 1998 U.S. EPA-funded survey by the University of Massachusetts found MTBE in 251 of 422 public wells in 19 states. A recent study of by the U.S. Geological Survey, reported April 29 to the EPA "blue ribbon" MTBE panel, found in a 12-state survey of New EnglandMid-Atlantic states, that using MTBE in gasoline results in a four- to six-fold increase in detection frequency. Another USGS study found MTBE detected in 21 percent of 480 wells in community water systems in a sampling of wells nationwide. MTBE has been detected in water in states such as Maine, Pennsylvania, Virginia, Texas, Kansas, New York, New Jersey, Georgia, Alabama, Colorado, New Hampshire, Massachusetts, Delaware and Arizona. LEGISLATIVE ACTION NEEDED PROMPTLY We need an all-out attack on MTBE. That is why I have introduced 4 bills: My first bill, S. 266 (the companion to H.R. 11, introduced by Rep. Brian Bilbray), would provide that if a state's reformulated gasoline rules achieve equal or greater emissions reductions than federal regulations, a state's rules will take precedence. The bill would apply only to states which have received waivers under Section 209(b)(1) of the Clean Air Act, the provision of law that allows a state to establish its own reformulated gasoline rules. California is the only state that currently has established its own reformulated gasoline rules. My second bill (S. 267) requires U.S. EPA to make petroleum releases into drinking water the highest priority in the federal underground storage tank cleanup and enforcement program. Leaking underground petroleum storage tanks and their pipelines are a major source of MTBE in drinking water. My third bill, S. 268, addresses motorcraft engines and accelerates the federal emissions standards to make them effective by 2001, consistent with California's standards. This bill, which covers spark-ignition outboard marine and personal watercraft engines, beginning in model year 2001, would speed up a complete fleet turnover by 2024. My fourth bill, S. 645, would authorize the U.S. Environmental Protection Agency to waive the two percent federal oxygenate requirement in any state if gasoline with less than two percent or with no oxygenates meets clean air standards. Here are four approaches. There may be others. In short, we need a legislative remedy that allows states to use gasoline rules that are performance based, achieve clean air goals and do not contaminate the drinking water. Current federal law prevents that kind of flexibility. CONCLUSION I have appended to my statement a list of the local governments, water agencies and others who support my MTBE legislation. You will see that there is broad support for ending the use of MTBE. Let me give you a clear message. We must get MTBE out of California's drinking water. Millions of Californians should not have to drink water contaminated with MTBE. Millions of Californians should not have to breathe MTBE in the air. I believe we can put in place a clean air policy using clean gasoline that does not contaminate our drinking water. I am not trying to wage a war for or against a particular oxygenate. If ethanol or another oxygenate achieves clean air goals in California and is safe for human health, for our air, water and natural resources, so be it. California's rules have shown we can make the cleanest gasoline in the world. I believe we can leave the formula for gasoline formulations to the experts and use an approach like California's predictive model which is performance based and does not rely on a prescriptive federal recipe for gasoline. We can have both clean air and clean water. I am not trying to "open up the Clean Air Act" or dismantle the Clean Air Act's protections. I am not trying to undo the reformulated gasoline program. The reformulated gasoline program has no doubt reduced unhealthy vehicle emissions. I am trying to get MTBE out of the drinking water. It is not needed for making clean-burning gasoline or for cleaning up the air. We should not contaminate our water to clean up our air. As CARB and other authorities have documented, we are poisoning our water by an indefensible policy that was intended to clean up our air. California has a better way. We should not continue to use MTBE when we have a sound alternative that keeps both our air and our water clean.

Will you be able to stay? Senator FEINSTEIN. I would like to stay for a little bit. Yes, thank you. Mr. BILIRAKIS. Mr. Franks. Bob Franks is from our side of the Capitol and represents a portion of the State of New Jersey and as far as this subject is concerned, I suspect the entire State of New Jersey. Bob. STATEMENT OF HON. BOB FRANKS, A REPRESENTATIVE IN CONGRESS FROM THE STATE OF NEW JERSEY Mr. FRANKS. Mr. Chairman, thank you very much for the opportunity to testify today. I am here to lend my support to H.R. 11, a bill that would allow the State of California to opt out of the 2 percent requirement of the Clean Air Act and to urge the committee to go one step further. There is compelling evidence that this requirement, which was designed to reduce carbon monoxide emissions in 10 areas of the country has led to another serious risk to the public health. A University of California study into_MTBE, which was released last November 12, concluded and I quote, "Within a relatively short period of time, MTBE has become one of the most highly publicized and widely released contaminants of surface and groundwaters. Introduced as a gasoline additive without adequate investigation of its fate, transport, and toxicity, it is now potentially a major threat to human health." As Mr. Pallone noted, in our State of New Jersey, the State Department of Environmental Protection reports that 400 private wells and 65 public wells have now been contaminated with MTBE. This contamination has been found in wells providing drinking water to homes and businesses throughout our State. One particularly serious threat is to the Kirkwood-Cohansey Aquifer, a massive storehouse of drinking water for southern New Jersey where wells have been found to have unacceptably high levels of MTBE. Mr. Chairman, I think it is important for the committee to note that many States are not waiting for the EPA to take more definitive action. Growing evidence and concern about the health and environmental impact has prompted Alaska, North Carolina, Missouri, Montana, and Maine to stop the use of MTBE. And as Senator Feinstein has said so articulately, back in March Governor Gray Davis of California ordered MTBE be eliminated from the gasoline supply of that State by 2003 and called the chemical, "a serious significant risk to California's environment.” I urge this committee, Mr. Chairman, to follow the lead of these States and to put an end to the use of MTBE in gasoline across the United States. Legislation that I am sponsoring, H.R. 1367, would ban the use of MTBE as a fuel additive over the next 3 years. By banning MTBE, we can prevent the spread of this chemical to other sources of drinking water. |
