California Air Resources Board

Invitation To Participate

The California Air Resources Board (CARB or Board) invites you to participate remotely for a public meeting to learn more about State Reserve funding to be used to co-fund light-duty vehicle purchases that align with and support continued implementation of Clean Cars for All (CC4A) projects. At the November 2024 Board meeting on the Fiscal Year 2024-25 Funding Plan, staff received direction to explore all options available to ensure continued implementation of air district CC4A programs. The Board directed the Chair to review and approve any funding allocations staff proposes for CC4A and the Drive Clean Assistance Program, without jeopardizing the implementation of the statewide Driving Clean Assistance Program, without putting funds at risk, and while recognizing the balance CARB is trying to achieve with district programs with the limited funds available.

CARB is prioritizing $12.4M in Carl Moyer State Reserve funds and other available balances to support Moyer-eligible zero-emission equipment, vehicles, and infrastructure projects that provide fuel or power to covered sources, with added flexibility for air districts with existing CC4A programs to prioritize projects under Chapter 8: Light-Duty Vehicles, supplementing zero-emission vehicles.

Staff propose amendments to the Carl Moyer Guidelines so air districts with CC4A programs will also have increased flexibility to fund projects that align with Chapter 8: Light-Duty Vehicles. Given the replacement vehicle of CC4A projects are zero-emission, staff are proposing to update the Carl Moyer Guidelines Appendix E: Cost-Effectiveness Limits, Discount Rates, and Capital Recovery Factors to apply the on-road zero-emission technology limit of Chapter 4: On-Road to Chapter 8: Light-Duty Vehicles to better align incentive amounts. Specifically, staff propose updating the current cost-effectiveness limit from $60,000 to $522,000, given that the replacement vehicle of CC4A projects would be zero-emission, aligning Chapter 4 and Chapter 8 cost-effectiveness limits. The updates will be shared during the public meeting along with a draft Appendix E.

The public meeting will be held via a Zoom meeting at the following date and time:

Background

Since 1998, the Carl Moyer Program has filled a critical niche in California's strategy to achieve clean air. The Carl Moyer Program provides grant funding for the incremental cost of cleaner-than-required engines, equipment, and emission reduction technologies. Emission reductions funded through the Carl Moyer Program must be surplus, permanent, enforceable, and quantifiable in order to meet the underlying statutory provisions and be creditable to the State Implementation Plan.

State Reserve funds are a portion of the Carl Moyer Program funds that are set aside to provide monetary grants focusing on a specific project type(s). Section 44286(d) of the Health and Safety Code gives CARB the authority to reserve up to 10 percent of Moyer Program funding to directly fund any project that is a covered source and is described in Section 44281. For Fiscal Year 2024–25, $12.35 million State Reserve funds will support Moyer-eligible zero-emission equipment, vehicles, and infrastructure projects that provide fuel or power to covered sources, with added flexibility for air districts with existing Clean Cars 4 All (CC4A) programs to prioritize projects under Chapter 8: Light-Duty Vehicles, supplementing zero-emission vehicles.
