Senator Mrskie. Our last scheduled witness this morning is Dr. Walter B. Hibbard, Jr., Director of the Bureau of Mines.

I understand Dr. Hibbard is accompanied by Mr. J. Wade Watkins, Director of Petroleum Research.

You may proceed, sir.



Dr. HIBBARD. Mr. Chairman, I am pleased to have this opportunity to testify before this committee. May I introduce my colleague, Mr. Wade Watkins, who is Director of Petroleum Research for the Bureau of Mines.

The Bureau of Mines has a long history of interest and research on the prevention of water and air pollution. As far back as 30 years ago, Bureau engineers and scientists provided guidance for the petroleum industry in methods for disposing of brines produced with oil by injection into subsurface permeable rock formations in such a manner that contamination of surface and subsurface waters would not


If I may digress for a moment from the written testimony, back in 1923 the Bureau of Mines entered a cooperative agreement with the General Motors Corp. and the Ethyl Gasoline Corp, in cooperation with the U.S. Public Health Service, to make experimental studies on the effects of ethyl gasoline and its combustion products.

Bureau monograph No. 2 which I have here is the result of these studies which were conducted in close cooperation with the Public Health Service.

In fact, Dr. R. R. Sayers, who subsequently became a director of the Bureau of Mines, was at that time our Chief Surgeon and also an officer in the Public Health Service.

Senator MUSKIE. Does that contain a summary or conclusion that might be well to include in the record at this point?

Dr. HIBBARD. This is a monograph which is largely concerned with information as a result of the studies. There is a summary but it is fairly complicated and more factual than it is interpretive.

Senator MUSKIE. Could that be available to the staff of the committee?

Dr. HIBBARD. This can be made available to your staff; yes, sir.

In 1957 the recognized competence of Bureau researchers in fuels combustion research was responsible for the initiation of cooperative research with the U.S. Public Health Service in its own laboratories. In fiscal year 1966 funds transferred from the Public Health Service were obligated in the following amounts: (1) Bartlesville Petroleum Research Center, $325,000; and (2) Pittsburgh Coal Research Center, $345,000.

A recent cooperative agreement was negotiated with the new Committee on Air and Water Conservation of the American Petroleum Institute for a 3-year research program at our Bartlesville Petroleum Research Center on the effect of fuel volatility on automobile exhaust

emissions. The total funds expected to be available from the American Petroleum Institute over the 3-year period are about $480,000.

The research studies will cover losses of automotive fuel from the fuel system and will probe the effect of changes in fuel volatility on the amount of hydrocarbon unburned in the combustion process. Hydrocarbons are lost to the atmosphere by evaporation from the fuel tank and by boiling from the carburetor.

Tentative allowable standards for evaporation loss have been suggested by air pollution abatement officials. At the same time that it becomes desirable to reduce losses from vehicular fuel systems, engineering changes made to meet exhaust hydrocarbon emissions standards have resulted in increased temperatures in auto engine compart

Changes in fuel formulations may be required to meet evaporation loss specifications. Moreover, it is possible that changes in fuel volatility would have deleterious effects on vehicular emissions.

It is expected that the experimental work will involve several fuels with volatility varied between 5 and 12 pounds Reid vapor pressure; other fuels to be included in the tests will have hydrocarbon-type distribution altered to remove the photochemically reactive material from components that might be lost through evaporation.

A part of the planned research will be a comparison of the emissions from fuels containing the national average amounts of lead antiknock additives with emissions from fuels formulated to have adequate antiknock quality with substantially less than average amounts of lead additives. The interest in this study is not upon lead per se but upon the effect of changing fuel formulations to allow a reduction in lead additive level.

It should be emphasized that the Bureau of Mines neither professes competence nor considers as part of its research mission the health effects of automotive emissions as air pollutants. This properly is a responsibility of the Public Health Service. The Bureau's research on fuels combustion is organized to (1) identify and measure the efAuents that are generated in fuels use, and (2) study the interdependence of factors in the vehicle and combustion system.

These factors encompass the fuel, oxidant, engine and combustion parameters, and the exhaust system. This research does include the kinds and amounts of the various components of the exhaust stream and their comparative reactivities in producing photochemical smog. It is factfinding relative to fuels utilization.

The Bureau's concern is to minimize air, water, and land pollution by

any and all effluents and residues—gaseous, liquid, or solid-resulting from minerals extraction and utilization, including fuels. We are pledged to work toward the objective of promoting conservation through the wise and efficient utilization of our mineral resources, while maintaining the quality of our environment.

Senator MUSKIE. Thank you, Mr. Hibbard. I have here a copy of a release from the Department of the Interior dated June 1, 1966, entitled “Better Gasoline Formulas Sought in New Government-Industry Air Pollution Research Program.” This release will be included in the record at this point.

[News release, Department of the Interior, Bureau of Mines) BETTER GASOLINE FORMULAS SOUGHT IN NEW GOVERNMENT-INDUSTRY AIR


Special “anti-pollution” gasoline formulas that may produce cleaner auto exhaust will be tested soon in a joint research program by the Department of the Interior's Bureau of Mines and the American Petroleum Institute.

Bureau of Mines Director Walter R. Hibbard, Jr., said today that under a newly agreed upon cooperative arrangement, the API will contribute $480,000 to the program and the Bureau will furnish research personnel and facilities.

Many different gasoline “recipes" will be devised and tested, Hibbard said, to determine which produce the cleanest exhaust when burned in a variety of engines under varying conditions. The results, he predicted, should prove indispensable to Federal, State, and local officials concerned with possible air pollution regulations covering gasoline-engine exhaust emissions, as well as to the petroleum and automobile industries.

Hibbard described the cooperative program as "another effort by Government and industry to meet their point responsibility for air pollution abatement." He added, "We believe that, in the long run, joint efforts of the kind typified in this agreement will prove to be the most effective way of combating the Nation's growing air pollution problems."

Bureau scientists will test two general classes of fuel, Hibbard explained. The first consists of gasoline without tetraethyl lead, the common anti-knock compound. Lead is toxic, and because increasingly large amounts of it are released into the atmosphere from auto exhausts, considerable interest has been aroused in research on possible new types of unleaded motor fuel to reduce air pollution.

Since removal of the lead requires “juggling the recipe” to preserve the fuel's anti-knock characteristics, the Bureau of Mines will test many different formulas of unleaded gas to determine which gives the best combination of performance and clean exhaust. The tests will cover commercially available unleaded gas as well.

The second class of gasolines to be studied, Hibbard said, are those containing a higher-than-normal proportion of volatile ingredients, such as pentane and butane. There is evidence to indicate that the exhaust from engines using such fuels contributes relatively little to the formation of smog. Hibbard noted, however, that fuel volatility can contribute to vapor lock in fuel lines and carburetors--a problem that would have to be overcome before such gasolines could become a commercial reality.

The joint research project is scheduled to last three years, and will include use of a wide variety of automobiles, representing most of the passenger car engine types on the market today. Most of the work will be conducted at the Bureau's Bartlesville (Okla.) Petroleum Research Center, which has for many years been a leading institution in research on efficient production and use of mineral fuels.

Senator MUSKIE. Included in that release is the following statement which I think supplements what you have already testified to this morning.

Bureau scientists will test two general classes of fuel, Hibbard explained. The first consists of gasolines without tetraethyl lead, the common antiknock compound. Lead is toxic and because increasingly large amounts of it are released into the atmosphere from automobile exhausts considerable interest has been aroused in research on possible new types of unleaded motor fuel to reduce air pollution.

One of the objectives of the study is to undertake to develop fuels which will operate without lead as well as they operate with lead.

Dr. HIBBARD. Fuels without lead additives are included in the study.

Senator MUSKIE. This study is being conducted under an agreement with the American Petroleum Institute?

Dr. HIBBARD. Yes, sir.

Senator Mrskie. And it is in part financed by funds which will be made available by the American Petroleum Institute?

Dr. HIBBARD. Yes, sir. Senator MUSKIE. What will be the Bureau's contribution to the cost of the study?

Dr. HIBBARD. Generally in these cooperative agreements there is a matching of contributions. Our contribution will be in providing facilities and people and the obtaining of information to carry out the tests and the preparation of reports.

Senator Muskie. Now are your studies in this field limited to the studies which you will undertake under that agreement?

Dr. HIBBARD. Our general studies in the field of air pollution are not limited to this particular agreement. We have undertaken work for the Public Health Service, mentioned in my testimony, which is concerned with the characteristics of emissions from auto exhausts, including diesels, under various conditions of combustion parameters.

In other fields we have undertaken work sponsored by the Public Health Service on studies of sulfur in coal and SO, removal from the stack effluents from the burning of coal. In addition we have funds of our own which have been reprogramed into this general area of air pollution.

Senator Muskie. Will there be any duplication between the studies conducted under your agreement with the American Petroleum Institute and

any of these other studies which you have undertaken? Dr. HIBBARD. No, sir; we make sure that the studies we undertake are complementary to our other work and are of use and interest to the Federal Government as well as to the sponsor.

Senator Muskie. So that any work that is done to develop substitutes for lead as an antiknock additive will be done under this agreement with the American Petroleum Institute?

Dr. HIBBARD. That is correct.

Senator MUSKIE. I would like to ask some questions related to your agreement with the American Petroleum Institute so that I may understand its implications. First of all there will be included in the record at this point a copy of your cooperative agreement with the American Petroleum Institute which is dated May 9, 1966.
