California’s Air Resources Board (CARB) has delayed its upcoming public hearing regarding the proposed amendments to its On-Road Heavy-Duty Engine and Vehicle Omnibus Regulation and its Low Carbon Fuel Standard Regulations.
The hearing was announced in September and was scheduled to be held on Nov. 20, after CARB announced its intent to amend its Low NOx Omnibus regulation amid its battle with the Federal government and truck manufacturers regarding the validity of regulations in the state.
CARB reported Friday the hearing on these items has been postponed to a future date and time. A subsequent notice will follow in the future with more information, including the date, time and location of the rescheduled hearing, CARB states.
The public comment period for the regulatory action, which began on Sept. 26, 2025, and which closes on Nov. 10, 2025, has not been extended, CARB adds.
This announcement comes just a week after U.S. District Judge Dena Coggins issued a preliminary injunction barring California from enforcing the terms of its Clean Truck Partnership.
