What’s new in California for 2023
If you operate in California, you need to be up to date on what the California Air Resources Board (CARB) is up to.
This coming year (2023) and the following year (2024), CARB has several new programs getting underway, as well as some long-standing programs that are changing. The programs with an “*” in front of them throughout this article are applicable to all carriers operating in California, not just those based in California or with an operating facility in California.
New programs
There are several CARB programs getting underway this year, including:
- Advanced Clean Truck and Advance Clean Fleet (ACT/ACF): This program will phase in the sales and use of zero emissions vehicles (ZEVs). Under ACT, manufacturers will be required to meet specific ZEV sales percentages starting in 2024. Under the ACF regulations, carriers will be required to start replacing certain California-based vehicles that have reached the end of their service life with ZEVs starting in 2024.
- *Heavy Duty Inspection and Maintenance (HD I/M): This program will require carriers to submit OBD data confirming the vehicle is operating within its designed emissions parameters. Registration for this program will begin during 2023, with reporting being required in 2024.
- *Roadside emissions monitoring devices (REMDs): These devices will be placed in areas where trucks and buses pass at low speed. As the vehicle passes, the device samples the air. If excessive emissions are discovered, the motor carrier operating the vehicle will receive a Notice to Submit for Testing (NST). The vehicle then must be taken to a certified testing location and pass an emissions test.
Other programs
Here is a short list of some of the other programs that would be applicable to most carriers operating in California:
- *Truck and bus regulation: As of January 1, 2023, the previous exemption applicable to vehicles with engines from MY 2007 to 2009 expires. This means that all diesel-powered vehicles with pre-2010 engines must be retrofitted with an engine that meets the 2010 emissions standards.
- *Transportation Refrigeration Unit (TRU): Diesel-powered transportation refrigeration units (TRUs) must meet specific emission standards (also, TRUs based in California must be registered with CARB). If the TRU cannot meet the standards as built, it must be retrofitted with emissions control technologies (contact your TRU vendor if you have questions on your TRUs).
- *Tractor-trailer greenhouse gas regulation: This regulation requires 53-foot box-type trailers and the tractors pulling them to meet specific aerodynamic and low rolling resistance tire requirements.
- *Heavy-Duty Vehicle Inspection Program (HDVIP): Any heavy-duty vehicle operating in California may be inspected at roadside locations to verify the vehicle is meeting the appropriate emissions standards. To assist with this program, California also requires all engines to have the emissions label in place.
- Periodic Smoke Inspection Program (PSIP): This program requires fleet owners to conduct specific annual emissions inspections once the vehicle is four years old. This program applies to any diesel-powered vehicle with a Gross Vehicle Weight Rating (GVWR) of 6,001 pounds or more. There is an exception that allows for every-other-year testing for certain vehicles with a GVWR of 6,001 to 14,000 pounds (Note: HDVIP and PSIP will be replaced by HD I/M and REMDs, likely in 2024).
Key to remember: If you operate in California, you need to comply with the applicable CARB emissions regulations.
