Industries in many urban areas are faced with stringent new source review requirements. Under which all emissions increases must be compensated for by obtaining emission reductions elsewhere in the basin. Yet, these emission reductions (known as offsets) are becoming more difficult and costly to obtain from existing stationary sources. To provide flexibility in siting new stationary sources, many have advocated the implementation of mobile source emission offset programs. These proposed programs would allow stationary sources to develop and implement mobile source control strategies using the emission reductions achieved from mobile sources to offset stationary source emission increases.
A number of federal and California legislative proposals related to the development of mobile source emission offset programs have been introduced since mid-1990. However, the provisions of mobile source offset programs raise a number of concerns related to air quality attainment planning. The primary concern is that many mobile source emission control strategies are already inherently relied upon (i.e. required by federal and state provisions) to achieve national ambient air quality standards. Furthermore, the majority of potential emission reductions from mobile sources may not be able to qualify under the criteria established by the Federal Emission Trading Policy. Caution must be exercised in developing any mobile source offset programs to ensure that actual emission reductions, above and beyond the reductions already required, are achieved.
