Are you using a CARB Truck and Bus exemption? If so, it’s time to update your data!
Under the California Air Resources Board (CARB) Truck and Bus regulation, a carrier cannot operate a diesel-powered vehicle with a gross vehicle weight rating (GVWR) of 14,001 pounds or more in California unless the vehicle has an engine that meets the 2010 emissions standards (a model year 2010 or newer engine).
The only exception is if the carrier is using one of the applicable exemptions. The main exemptions that carriers can use include:
- Low-use vehicle exemption: This can be used if the vehicle that does not meet the 2010 emissions standards, provided the vehicle does not exceed 1,000 miles in California.
- NOx Exempt Area exemption: This allows vehicles that do not have an engine meeting the 2010 emissions standards to operate only in specific areas within California (specifically Alpine, Colusa, Del Norte, Glenn, Humboldt, Lake, Lassen, Mendocino, Modoc, Monterey, Northern Sonoma, Plumas, San Benito, San Luis Obispo, Santa Barbara, Santa Cruz, Shasta, Sierra, Siskiyou, Tehama, Trinity, and Yuba counties), if the vehicle is equipped with a particulate matter filter (or PM filter, also known as a diesel particulate filter, or DPF).
To use either of these exemptions, the carrier and vehicles must be registered in the CARB Truck Regulation Upload, Compliance, and Reporting System (TRUCRS).
TRUCRS registration
Registering involves creating a TRUCS account and entering company information y (an email address, company name, address, contact information, etc.). Once the carrier is registered, all vehicles that will be using one of the exemptions to operate in California must also be registered in the system. Registering the vehicles will require details on the vehicle (vehicle body type, VIN, engine model, current mileage, etc.) and what exemption is being used (referred to as “Compliance Options”).
Annual reporting
Each January, carriers with vehicles using the low-use option must go into TRUCRS and report the current mileage on vehicle (the odometer reading at the end of the previous year). The reporting involves accounting for all miles put on the vehicle over the previous year and the miles in California. If the miles in California did not exceed 1,000, the vehicle is compliant.
Carriers that have vehicles using the NOx Exempt Area exemption must go into TRUCRS during January, report the status of the vehicle, and indicate the vehicle will continue to operate under this exemption.
If the annual reporting is not done, the vehicle loses its ability to use the exemption.
Still need to comply with ECL, roadside emissions, PSIP, GHG, ACF, and CTC
If a vehicle is registered in TRUCRS and is using one of the Truck and Bus regulation exemptions, this does not exempt the vehicle from the other CARB requirements. The vehicle will still need to have its emissions control label (ECL), comply with the CARB emissions standards for a vehicle of that model year, have its emissions periodically inspected (annual once it is four years old), have the required aerodynamics and low-rolling resistance tires if pulling a 53-foot trailer, be registered in the TRUCRS Advanced Clean Fleet (ACF) database (if it is being operated by a high-priority fleet), be registered in the Clean Truck Check (CTC) program by January 31, 2024, and comply with the CTC OBD/smoke opacity testing requirements (uploading OBD or testing data is required starting in July of 2024).
Key to Remember: If you want to operate a diesel-powered vehicle with a GVWR of 14,001 pounds or more in California with an engine older than model year 2010, you need to use one of the exemptions. To use the exemption, you need to register in CARB’s TRUCRS and update your vehicle information every January.
