California has withdrawn its request for a waiver and authorization for the addition of the Advanced Clean Fleets (ACF) Regulation to its emissions control program. At this time, CARB is evaluating next steps. CARB is not enforcing the existing portions of the ACF Regulation that require a federal waiver or authorization, such as the portions of the ACF Regulation that apply to high priority and drayage fleets. However, not all elements of the ACF Regulation require a federal waiver or authorization. The state and local government fleets portion of the ACF Regulation remains unaffected. Because CARB is committed to reducing air pollution to protect public health, we encourage affected industries to continue reducing their emissions and we look forward to continued partnership in these efforts.
The Advanced Clean Fleets regulation primarily affects medium- and heavy-duty on-road vehicles with a gross vehicle weight rating (GVWR) greater than 8,500 pounds, off-road yard tractors, and light-duty mail and package delivery vehicles.
While this tool is intended to assist regulated entities in finding information on the Advanced Clean Fleets regulation, it does not alter, modify, or override the terms of any CARB regulation, is not a substitute for reading the regulation, or constitute legal advice. It is the sole responsibility of fleets to ensure their compliance. In the event any discrepancy exists between this tool and the Advanced Clean Fleets regulation, the regulatory text of the Advanced Clean Fleets regulation applies. Fleets with multiple operations may be subject to different components of the Advanced Clean Fleets regulation. View each operation individually within this tool.
