332 ELECTRIC VEHICLES down the road, looking at a diesel-powered truck, or looking overhead at a jet engine. Senator BAKER. If the Senator will yield, Mr. Chairman, I think as chairman of the American Petroleum Institute that Mr. Dunlop should consider calling this additive the "Scott exuberant excretion of noxious materials additive." [Laughter.] Mr. DUNLOP. We will take that under advisement. Senator Scorr. Well, we* are all experts here on that subject. [Laughter.] Senator BAYU. Mr. Prouty?, Senator PROUTY. Thank you. Your statement is excellent in all respects, and I might say, is very reassuring to me. I find that many of my colleagues have a much greater technical knowledge of this question than I possess, so my questions will have to be very limited. It seems to me that we have been concerned with this problem of pollution for a relatively short period of time It has existed, but no one has been very much concerned with it until recently. And I wonder just how long the oil industry and the automotive industry and others have been engaged in research. Mr. DUNLOP. Broadly, we have been engaged in research in pollution for actually as long as 30 years. However, in our industry we try to identify the pollution problem in terms of the process pollutionthat is, the pollution which comes about as a result of our refineries or the oil wells that produce salt water and how we get rid of that salt water. We have been spending great sums of money. And I think we have process pollution under a much higher degree of control and elimination than we have the 'second area of pollution which I will refer to as product pollution; that is, the utilization of our products. This is the area to which attention has been primarily directed this morning, the utilization of gasoline or, in a minor way, the diesel and jet fuels in the particular systems that use those. In terms of the amount of money being spent by the oil industry, last year the industry itself, without regard to this API effort, spent somewhere in the neighborhood of $10 million on the pollution problem. And that,covers the whole spectrum of the pollution problem. This has been a very large subject with us. I have been in this industry almost 35 years now, and I am conscious of its existence, going back to my early association with the industry. Senator PROUTY. But research with respect to the particular problem with which we are concerned this morning is being intensified? Mr. DUNLOP. It is being intensified, and frankly is of more recent origin. I have the privilege of being here as chairman of the American Petroleum Institute. Several years ago our API effort was in a modest area of maybe a quarter of a million dollars a year. The API effort is now between two and two and a half million dollars in this area of pollution. And from the API point of view it comprises somewhat-it is about a quarter of our budget. I mention that as an indication of the level of concern and involvement, if you will, that we feel in this matter. Senator PROUTY. Thank you very much.
