ITEM Staff Report to the Assembly on Recommended Standards for the Composition of Gasoline. The 1970 California Assembly adopted Assembly Bills Numbers 80 and 81 directing the Air Resources Board to establish maximum standards of unsaturation for gasoline sold in the south Coast air Basin (AB 80) and requires the State Air Resources Board to establish, under specified conditions, maximum standards for volatility of gasoline sold in the State of California (AB. 81). ITEM Statement for Hearing on Lead. The hearing on the petition of the Environmental Defense Fund regarding an exhaust emission standard for lead and the definition of lead is opened. The Air Resources Board held a number of hearings on lead during the past year. Several of these were concerned with the effects of lead and the need for an ambient air quality standard. At that time we heard about the occurrence of lead in the environment, the sources of the lead, and the health effects. The Air Resources Board took all this into account when it set the air quality standard for lead. There is nothing to be gained by going over all this ground again. The purpose of today's hearing is to consider the proposed exhaust emission standard and definition of lead. I urge those who testify to keep this in mind. If not, I will have to remind you of it. ITEM Outlook for Further Control of Hydrocarbons and Oxides of Nitrogen. The standard of 0.1 ppm for one hour for oxidant is fairly stringent in light of the present air quality in the metropolitan areas of the State. Oxidant levels above 0.1 ppm have occurred frequently during 1970; there were 9 days during which ozone levels of 0.5 ppm or greater were reported by the Los Angeles County Air Pollution Control District. In recommending the standard for adoption, the Technical Advisory Committee reported that this standard might not be achieved with the present control programs. The committee reported that to meet the standard, emissions would need to be reduced to levels below those now proposed, and perhaps industries and fossil-fuel power plants would need to be made essentially emission free or moved from the South Coast Basin. Oxidant is a product of atmospheric reactions involving hydrocarbons and oxides of nitrogen. this report reviews the present control programs in the South Coast Basin and indicates what needs to be done in addition to the present programs in order to further reduce the emissions of these pollutants. ITEM Staff Report on Used Car Controls In 1970, the Air Resources Board considered the possibility of accreditation of exhaust control systems for the 1955-65 model vehicles. these devices were proposed by several companies, including major automobile manufacturers. A control system developed by American Pollution Controlled, Inc., was accredited on the basis that emissions met the standards specified in the Health and Safety Code. A condition of the accreditation was that 50 of the devices be supplied to the Board for installation on state cars. This will permit more extensive evaluation of possible adverse effects on performance and driveability. The prospect of finding that devices are available for installation on used cars at time of transfer of ownership has been altered by the announcement in December of the withdrawal of Norris Industries from its joint venture with American Pollution Controlled, Inc. Since the Board's resolution of accreditation specified both companies as applicants, the Norris withdrawal has the effect of negating the Board's September action accrediting the APC device. American Pollution controlled, Inc., has been seeking an alternative partner with manufacturing and distributing capability. If successful, the new partnership could apply for renewed accreditation of the system already tested. The development of the device of other companies has not reached the point where that can be considered for accreditation by the Board.
