The Advanced Clean Fleets (ACF) regulation is now effective as of October 1, 2023. The Office of Administrative Law (OAL), who is tasked with determining whether a proposal procedurally complies with the state’s regulatory law, has reviewed and approved the law.  Here are some key points you should be aware of:

• Compliance requirements for High Priority Fleets and State and Local Government Fleets will begin January 1, 2024. 

• Starting January 1, 2024, only zero-emission drayage trucks (trucks that transport cargo to/from CA’s intermodal seaports and railyards) can register in the CARB Online System. Internal combustion engine (ICE) drayage trucks that intend to continue or begin operations at a California seaport or intermodal railyard must register with CARB by December 31, 2023.

• Initial reporting for High Priority Fleets is due February 1, 2024 and for State and Local Government Fleets on April 1, 2024.

The California Air Resources Board (CARB) staff has released several informational Fact Sheets explaining the regulation that can be found here. 

CRTA has also issued information and an infographic explaining how CNG trucks can continue to be purchased under the rule. CNG trucks fueled by renewable natural gas (RNG) are a readily available alternative to “legacy” diesel trucks that can immediately help fleets meet their sustainability goals. These trucks are a low carbon, cost-effective, CARB-certified option with a built-out fueling network.

We urge you to do the research to discover how a CNG truck is right for you. You can also join us at the 2023 Natural Gas Vehicle Summit (NGV23) in San Diego on October 23-25, 2023 to learn more and test drive the new Cummins X15N Engine.
