This paper documents the historical trends of pollutant emissions and ambient air quality for the South Coast Air Basin (SCAB) for the period 1965-1974. Emission trends for nitrogen oxides. reactive hydrocarbons, and carbon monoxide are developed. A detailed appendix describes the methodology and presents the latest test information -- in particular the contribution of evaporative emissions from light-duty vehicles. Basin-wide and county trends are presented to characterize the overall changes as well as the spatial distribution of emissions. Ambient concentrations of total nitrogen oxides (NO_x), nitrogen dioxide (NO_2), oxidant (OX), and carbon monoxide (CO) are compared to the emissions changes during the same period. Detailed analyses of air quality indices, including extreme levels, average values. and frequency of standard violation are presented for each pollutant. The final section of the paper discusses current and proposed control strategies and their impact on future air quality.

|Additional Information:||This paper was presented at the Conference on Strategies for Air Pollution Control in the South Coast Air Basin, sponsored by the Environmental Quality Laboratory and Industrial Associates at the California Institute of Technology on 2-3 December 1975. The comments of several people in attendance at the conference were helpful to the authors in preparing this memorandum. Several members of the California Air Resources Board Technical Staff, Donald Bratton, Spencer Duckworth, John Kinosian, Howard Linnard, and Jack Paskind, deserve particular thanks for contributing data and comments. The preparation of this paper was a grant from the Ford Foundation to the Environmental Quality Laboratory No. 740-0469).|
