The California Environmental Quality Act (CEQA) generally requires state and local government agencies to inform decision makers and the public about the potential environmental impacts of proposed projects, and to reduce those environmental impacts to the extent feasible. This page contains information about the CEQA process and links to general project comment letters written by CARB and local air districts. This is not intended to be an exhaustive list, but a helpful starting point for those interested in air quality and the CEQA process. This list will be refined and updated as new resources become available, and as public comments are received.

Some of the links below lead to non-CARB resources, but provide information that may be helpful to individuals interested in air quality and the CEQA process.  CARB cannot attest to the accuracy of these sites, and linking to a non-CARB site does not constitute an endorsement by CARB or any of its staff.
