The California Air Resources Board (CARB or Board) is pleased provide the updates to the Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) Guidelines (Guidelines), Chapter 4: On-Road Heavy-Duty Vehicles (Chapter 4). On November 19, 2021, the Board approved amendments to the Carl Moyer Program cost-effectiveness limits and funding caps for optional advanced technology and zero-emission replacement on-road projects for the on-road category. During the hearing, stakeholders indicated a desire for further administrative changes, outside the immediate scope of the Board hearing, to streamline administrative requirements and processes that would better ensure program participation and accountability in the program.
CARB staff has had numerous discussions with air districts and stakeholders, regarding these issues. As a result of these collaborative efforts, feedback received at the March 1st, 2022 public meeting, and under authority delegated to the Executive Officer by Resolution 21-24, CARB staff are providing updates to Chapter 4 of the Carl Moyer Program Guidelines for On-Road Heavy-Duty Vehicles.
Staff’s presentation, and any additional related documents, have been made available on CARB’s website.
