The paper directs attention toward the Transportation Control Plans in an effort to describe the problems encountered by the states in the implementation of the Clean Air Act. The control plans which are aimed at the two pollutants, carbon monoxide (primary pollutant) and photochemical oxidants (secondary pollutant), is the summation of individual actions that will, when taken collectively with stationary source controls and the Federal Motor Vehicle Control program, reduce pollutants to the levels prescribed by the National Ambient Air Quality Standards. The Control plans are necessary in those areas where the Federal Motor Vehicle Control Program and control of stationary sources of air pollution will not be sufficient to attain the required standards. The measures included in various Control Plans are broadly grouped into those which include additional stationary source controls, inspection and maintenance programs, reduction in vehicle miles (VMT), retrofit emission controls for in-use vehicles, and gasoline supply limitations. The relationship between the secondary pollutant characteristics and the VMT group of transportation control measures is examined. Region-wide reductions in VMT are advocated. Diversion of commuter traffic from autos to mass transit is seen as the cornerstone of VMT reduction plans. The concept of a balanced incentive/disincentive strategy for reducing VMT needs to be reevaluated. The impact of the parking surcharge is discussed. The problems in implementing the Transportation Control Plans stem from the broadly structured language of the statute, and the fact that the plans that have been developed will require modification.
