CARB is responsible for actions to protect public health from harmful effects of air pollution in communities of California. CARB is the leader in developing air emission control programs to reduce air emissions from mobile and stationary sources.

Mobile sources include on-road and off-road vehicles. Dry cleaners, portable engines, and chrome plating shops are just a few examples of stationary sources. CARB has promulgated Airborne Toxic Control Measures (ATCM) for several source categories that are codified in the California Code of Regulations (CCR).

If you are looking for information regarding any new ATCMs under development that have entered the formal rulemaking process or amendments to existing ATCMs, please refer to CARB's Rulemaking Activity website.
