REPORT OF THE CONFERENCE ON AIR QUALITY AND AUTOMOBILE EMISSIONS MAY 5, 1975 TO THE COMMITTEE ON ENVIRONMENTAL DECISION MAKING

The conclusions and recommendations are presented which were reached by the conference which was designed to assess the current situation and identify key issues related to air quality and automobile emissions. The conference came to the conclusion that emission standards for hydrocarbon and carbon monoxide (0.41 and 3.4 gm/mi for the 1978 and subsequent model year light-duty vehicles should be maintained at the current statutory levels. It was considered feasible, with catalyst technology, to achieve the statutory emission standards for nitrogen oxides (0.4 gm/mi) in 1978. The cost of achieving this standard are summarized. A two-car strategy should be implemented if the statutory emission standard (for NOC) is relaxed. The technologies adopted however, must not significantly increase ambient concentrations of sulfuric acid and acid sulfates. The relaxation of existing standards for regulated air pollutants is not justified. The health effects of non-regulated pollutants must be studied. Air quality standards must be achieved while improving fuel economy. There is also a need to develop emission standards and effective controls of sources other than light duty motor vehicles.
