Latest California Air Resources Board truck and bus program rolling ahead
The California Air Resources Board (CARB) is starting a new emissions program this year called the Clean Truck Check program.
The requirements of this program will impact any non-gasoline powered vehicle operating in California with a gross vehicle weight rating (GVWR) of 14,001 pounds or more. The program, originally known as the Heavy-Duty Inspection and Maintenance (HD I/M) program, has several benchmarks occurring over the next year that will impact all carriers operating non-gasoline powered vehicles in California.
Overview
This program will require owners to submit downloads of the vehicle’s onboard diagnostic (OBD) data twice per year. The data must be submitted to CARB based on the vehicle’s license renewal date (California-based) or the last digit in the VIN (out-of-state), and then six months later.
This data is found in the engine (electronic) control module (ECM) and can be accessed through the OBD port (typically, a OBD2, J1708, J1939 connection point). It must be downloaded using a device authorized by CARB or through a telematics company that has an agreement with CARB.
Once the program is fully implemented, if downloads are not submitted the vehicle’s California registration will be suspended. If the vehicle is based in California, this means the California license plate will be suspended. In the case of an out-of-state vehicle, the California portion of the vehicle’s IRP registration will be suspended.
Current status
Currently, CARB has deployed Roadside Emissions Monitoring Devices (REMDs) that sample the air as vehicles pass and send a Notice to Submit to Testing (NST) to the vehicle owner when the REMD detects a potential high emitter. To satisfy the NST, the vehicle owner must submit either OBD data showing the vehicle is compliant with the emissions requirements or proof of passing a physical emissions inspection at an authorized location.
They are also in the process of certifying devices that can be used to download the OBD data. CARB is also testing the database that is being developed to house and use the data received from vehicle owners.
Upcoming dates
Here are key benchmarks for the Clean Truck Check program for the remainder of 2023 and 2024:
- October 2023: Vehicle owners establish their accounts, begin uploading vehicle data, and pay the related fees.
- January 2024: Not complying with a Notice to Submit to testing will result in registration suspensions and fines (no more warnings). Payment of program registration fees is required.
- July 2024: Owners are to start submitting OBD data and the periodic smoke inspection program ends (this is the program that required annual emissions testing for vehicles based in California).
- TBD: Four years after initial implementation, the download and submission will be required four times per year, rather than just two.
Key to Remember: If you operate vehicles in California, you need to be keeping an eye on the Clean Truck Check program as it rolls out.
