California Air Resources Board Withdraws EPA Waiver Request

On Tuesday, January 14th, the California Air Resources Board (CARB) announced that it had withdrawn its request for a waiver from EPA to implement its Advanced Clean Fleets rule.

The Advanced Clean Fleets rule would have required all medium- and heavy-duty vehicles sold into California, including almost all motorhomes, to be zero emission vehicles by 2036 and would have required fleet owners to phase in increased percentages of zero emission vehicles between now and 2035. This would have impacted RV rental companies who had fleets of 50 or more motorhomes operating in California.

While the Advanced Clean Fleets rule withdrawal does impact the RV industry somewhat, this latest action by CARB does not affect the Advanced Clean Trucks rule in any way. EPA had already approved California’s waiver for the Advanced Clean Trucks rule in April 2023 and there is no indication that CARB is changing track on that rule. 

As always, the most up to date information on Advanced Clean Trucks in California is available here. The RV Industry Association remains engaged with CARB and our representatives in Sacramento to try and find a solution to this rule.
