South Coast AQMD’s Transportation Programs are responsible for Rule 2202 and Assembly Bill 2766. Rule 2202 – On-Road Vehicle Mitigation Options provides employers with various options to reduce mobile source emissions generated from employee commute trips or implement mobile source emission reduction programs. Employers with 250 or more employees at a worksite are subject to Rule 2202 and are required to submit an annual registration to implement an emission reduction program that will reduce emissions equivalent to a worksite specific emission reduction target. Approximately 1,200 employers are subject to Rule 2202 and must implement an emission reduction program to reduce emissions from employee commute trips.

On-road motor vehicles, including cars, trucks, and buses, represent one of the largest sources of air pollution in the South Coast Air Basin. Vehicle emissions from exhaust contribute to unhealthful levels of ozone, particulate matter, and toxic air contaminants. To protect public health, Assembly Bill 2766, also known as the Motor Vehicle Subvention Fund Program was adopted in 1990. The goal of the bill was to provide a revenue stream for programs to reduce air pollution from motor vehicles and for related planning, monitoring, enforcement, and technical studies. About 162 cities/counties in the South Coast AQMD are participating in the AB 2766 Subvention Program to reduce emissions from motor vehicles.

AB 2766 revenue is distributed by the South Coast AQMD on a quarterly basis to the participating cities and counties in the South Coast Air Basin based on a prorated share of their population. The Transportation Programs Unit serves as a resource to cities and counties by providing guidance in project identification, development, quantification, and reporting.
