With the final implementation of the 'bubble policy' for stationary sources, EPA is now investigating the possible implementation of an averaging concept for mobile source emissions. Emissions averaging is meant to provide motor vehicle manufacturers with greater flexibility in determining the mix of vehicles/engines, while at the same time permitting no degradation in the air quality benefits derived from controlling motor vehicle emissions. This paper will examine the major benefits of the averaging concept and will identify the important design considerations which should affect the final form of any averaging concept. The analysis of these important design considerations will be used to identify design criteria which will be necessary for a successful averaging program. (Jensen)
