Hot Off The Press: The July Update On the New CARB Diesel Emissions Regulation

The California Air Resources Board (CARB) officially announced its Heavy Duty Inspection Maintenance Regulation (HD I/M) Program back in December, and phase-in began in January. This program is now known as the Clean Truck Check, a much more descriptive term that tells it like it is.

Similar to the California Smog Check program for light-duty vehicles, heavy-duty diesel vehicles that operate in California with a GVWR of more than 14,000 pounds are now subject to periodic emissions testing. When trucks fail to meet emissions standards, they are cited for repair. This new CARB diesel emissions regulation is aimed at improving public health by reducing air pollution throughout the Golden State.
In January, if your vehicles were identified as high emission producers by roadside emissions monitoring equipment, you received a Notice to Submit to Testing (NST) to pass a CARB compliance test within 30 days.

That was then. This is now.

CARB Is Putting The Pedal To The Metal And Rolling Out The Next Phases Of The Clean Truck Check Program:

The three-month open reporting season starts October 1, 2023, and runs until December 31st.

Fleet owners and owner-operators will need to meet initial reporting requirements within the Clean Truck Check database system.

Be prepared to supply company and fleet information, U.S. Department of Transportation (DOT) number, and vehicle identification number (VIN), along with make, model, fuel type, and more info for the database. A fee of $30.00 is charged, per vehicle, that is registered in the database as your 2023 annual compliance fee and compliance certificate that indicates that you have met the Clean Truck Check requirements. To operate legally in California in 2024, you’ll need to repeat this process in January.

Expect periodic vehicle testing to be required in July 2024

You will need to report proof of passing a diesel emissions test for each vehicle within 90 days of that vehicle’s DMV registration renewal date. Most vehicles will be required to undergo and submit the results from one compliance test in 2024, and by 2025, testing will be necessary twice per year. The Periodic Smoke Inspection Program (PSIP) ends because the Clean Truck Check Program takes its place.
