With its Advanced Clean Trucks (ACT) and low-NOx Omnibus regulations hanging on by a thread, the California Air Resources Board (CARB) announced last week it will hold a public hearing in July to consider approving for adoption proposed amendments to the ACT regulation and the Zero-Emission Powertrain Certification test procedure.
Set for 10 a.m. PT on July 24, CARB states its public meeting will address amendments adopted in October 2024 that primarily provide manufacturers with greater flexibility to comply with the ACT regulation, including extending the period that manufacturers can offset deficits from one year to three years. CARB states the amendments consist of minor, administrative changes that have minimal cost impacts and no emissions impact.
In accordance with the Administrative Procedure Act, CARB states interested members of the public may present comments orally or in writing during the hearing and may provide comments by postal mail or by electronic submittal before the hearing. The public comment period began May 30 and comments must be received no later than July 14, 2025.

Comments submitted outside that comment period are considered untimely. CARB may, but is not required to, respond to untimely comments, including those raising significant environmental issues. CARB also encourages members of the public to bring to the attention of staff in advance of the hearing any suggestions for modification of the proposed regulatory action. Comments submitted in advance of the hearing must be addressed to one of the following: Clerk of the Board, California Air Resources Board, 1001 I Street, Sacramento, CA 95814, or online here.
Finally, CARB states inquiries concerning the substance of the proposed regulatory action may be directed to the agency representative Paul Arneja, Manager In-Use Control Measures Section, at (279) 208 7342 or (designated back-up contact) Katherine Talamantez, Air Pollution Specialist, at (916) 282-6265.
