CARB recently announced that, in addition to the possibility of a new, lower NOx engine standard, it is currently in the process of evaluating existing regulations affecting new and in-use heavy-duty engines and vehicles warranty and durability requirements.

 

To support this work, CARB staff is forming six stakeholder workgroups on the following subjects:  

•Certification Standards and Test Procedures 

•Compliance with In-Use Standards for Emission Certification 

•Extended Warranties  

•Durability/Useful Life 

•OBD Workgroup 

•CARB Emissions Inventories (EMFAC) Workgroup 

 

Fleet representatives interested in participating in any of the workgroups listed above can email CARB at lownox@arb.ca.gov identifying the workgroup(s) you would like to join, your full name, your company or affiliation, and your contact information. For more detailed information, click here.
