The California Air Resources Board (CARB) continues to ratchet up the emission standards for heavy duty trucks, especially those in the drayage market, and the Truck and Engine Manufacturers Association (EMA) are suing the state for failure to follow the federal Clean Air Act’s mandatory four-year lead time before new emission standards are adopted.
On December 22, 2021, CARB adopted rules requiring truck manufacturers to comply with more stringent emission rules beginning January 1, 2024. This two-year window is in clear violation of federal regulations and does not provide manufacturers enough time to design, test and build CARB compliant equipment.
A recap of the CARB rules below:
Effective January 1, 2023, all 2007-2009 model engine trucks will be prohibited from port service in California. Engines prior to 2007 were previously banned.
Effective January 1, 2024, all new trucks entered into the state’s drayage truck registry are required to be zero emission vehicles (ZEV). Any trucks 2010 or newer currently in the drayage registry will be allowed to continue to service California’s port for thirteen years or 800,000 miles, whichever comes first.
