The California Air Resources Board (CARB) has been sending out notices to applicable vehicle owners, requesting that they register with the new Heavy-Duty Inspection & Maintenance rule. Any owner/operator of a 14,000 GVWR truck or heavier, must report their equipment into the new database developed by CARB as well as pay a per truck annual compliance fee. Along with registering, the fleet owner is then required to conduct and submit annual opacity or emission controls inspections done by a 3rd party in order to obtain the vehicle’s annual registration paperwork. It was recently noticed to all applicable businesses and vehicle owners that the testing requirement of the rule has been postponed for the 2024 year, and will take effect in 2025. Currently, CARB is still awaiting an approval waiver from EPA Region 9. CARB is being challenged on the several of their approved rules, specifically the Advanced Clean Fleets regulation, which pushes businesses to expedite the deployment of electric vehicles within a fleet. Stay tuned for more updates.
