State law provides ARB with the oversight responsibility and authority to monitor local district implementation of California's incentive programs.  Incentive Programs include the Carl Moyer Memorial Air Quality Standards Attainment (Carl Moyer) Program, Lower Emission School Bus (School Bus) Program, Air Quality Improvement (AQIP) Program, and Proposition 1B: Goods Movement Emission Reduction (Goods Movement) Program.  This page provides links to the procedures that guide ARB incentive program review, reports and responses for completed program reviews, a list of upcoming program reviews, and related reports from State auditing agencies.

For questions related to program reviews, contact Yvonne Sanchez at (626) 575-6618.
