The California Air Resources Board (CARB) staff invites you to participate in a HD I/M workshop, via Zoom, on the evening of May 27, 2021.  At this evening event, staff plans to review background information on HD I/M program development and provide an overview of the potential program requirements. Staff will also discuss potential compliance assistance mechanisms geared toward small fleets to aid them in meeting the potential requirements. Staff will not present any new material at this workshop that has not already been discussed in previous meetings. Instead, this evening workshop is to provide an opportunity specifically for stakeholders who may not have been able to attend previous daytime meetings to learn more about the developing HD I/M program and provide feedback and comments. In accordance with Governor Newsom’s Executive Orders N-29-20 and N-33-20, as well as in accordance with recommendations from the California Department of Public Health, this workshop will be conducted remotely via webinar.

The workshop will be held via Zoom webinar at the following date and time:

Senate Bill (SB) 210, signed into law by Governor Newsom on September 20, 2019, directs CARB to develop a HD I/M program to ensure heavy-duty vehicles operating in California have properly functioning emissions control systems and that emissions-related malfunctions are repaired in a timely manner. SB 210 also requires CARB to implement pilot program activities that develop and demonstrate technologies that show potential for readily bringing vehicles into the program, and to work with our State agency partners to adopt and implement the program within two years of completing a pilot program. To that end, CARB has undertaken a variety of pilot program studies and demonstration projects in consultation with Stage agency partners and interested stakeholders, and last discussed those pilot program activities at a November 16, 2020, HD I/M workgroup meeting. Staff’s presentation on the status of the SB 210 pilot program activities is available on CARB’s website. Later this summer, staff expects to post the report on the findings of all the pilot program activities on its HD I/M website. The full text of SB 210 is available from the California Legislative Information website.

This will be CARB staff’s fourth public workshop since 2019 to discuss HD I/M program development. The previous public workshops were conducted on February 11, 2019, January 29, 2020, and August 12, 2020. The August 2020 workshop was also conducted via webinar/teleconference in accordance with Governor Newsom’s Executive Orders N-29-20 and N-33-20, as well as in accordance with recommendations from the California Department of Public Health. 

CARB staff has also conducted nine HD I/M workgroup meetings since 2019 to discuss HD I/M program technical components and the program development process. The HD I/M workgroup is an on-going forum for truck and fleet owners, trucking industry representatives, non-governmental organization representatives, and other interested and knowledgeable stakeholders to identify, discuss, and evaluate key technical and programmatic components of a future, comprehensive HD I/M program. Public workshops and workgroup meetings will continue throughout 2021. For information and presentations from all previous public workshops and workgroup meetings, please visit CARB’s website.
