329 ELECTRIC VEHICLES and the automotive industry, with the guidance and standard-setting functions being provided by the Government? Mr. DUNLOP. I don't see any other way, sir, to have it resolved. We can't conduct our business in a vacuum. The automobile industry can't do likewise. I think you have got to look at a systems approach, if you will, to this problem. Senator BAKER. I agree. One more question, if I may. You referred to the percentage improvement in hydrocarbons and hydrocarbon emissions, and indicated that we might reach the point of 90-percent improvement. With some rough arithmetic, if we start with the assumption that an uncontrolled internal combustion engine of typical design and performance would produce about 1,300 parts per million of unburned hydrocarbons, if we improved it to 90 percent it would still be at 130 parts per million. According to the testimony received in Los Angeles, this would be intolerable. Those figures I don't vouch for, by the way, but does that generally coincide with your views? Mr. DUNLOP. Those figures are different, frankly, than those that I have in mind. I would be pleased to submit for the committee, if you wish, the precise figures. The figures that I had in mind, frankly, were a little lower than that. They were between somewhere in the neighborhood of 500 to 600 pounds of hydrocarbons per vehicle per year. Somewhere in that level. And this, frankly, I would like to check, sir, rather than making a statement at this point in time. Senator BAKER. I would be most happy to have that. Senator BAYH. Without objection, we would be glad to have any statistical data that you have to include in the record. Mr. DUNLOP. I did quote figures, 1.5 per car down to 0.5 pounds per vehicle per day. If you take 1.5 a day, you are dealing in the neighborhood of 530 pounds per year. Senator BAKER. The indication the committee received in Los Angeles was that the ultimate objective, in order to improve and then stabilize the atmospheric situation of the Los Angeles Basin, for example, would be in the range of 35 to 50 parts per million. Mr. DUNLOP. I would agree with that. That is the general objective to which we are striving. Senator BAKER. Do you think it is attainable? Mr. DUNLOP. Yes. Let me say-I don't want to make an unequivocal statement obviously-I think they are within the bounds of realism. Put it that way at this point. (Subsequently, Mr. Dunlop submitted the following correspondence for the record:) AMERICAN PETROLEUM INSTITUTE, New York, N.Y., April 3, 1967. Hon. JENNINGS RANDOLPH, Chairman, U.S. Senate Committee on Public Works, New Senate Office Building, Washington, D.C. DEAR MR. CHAIRMAN: During our testimony before the Subcommittee on Air and Water Pollution and the Committee on Commerce on March 17, 1967 on S. 451 and S. 453 on behalf of the American Petroleum Institute, we indicated our intention to supplement and elaborate on our remarks regarding the accomplishments to date and the prospects for increased control of motor vehicle emissions powered by internal-combustion engines. 79-607 0-67-22
