Truck Improvement/Modernization Benefitting Emission Reductions (TIMBER) Program


The Truck Improvement/Modernization Benefitting Emission Reductions (TIMBER) Program takes the current criteria of the Carl Moyer Fleet Modernization program and streamlines the requirements for both participants and air districts. The goal of the TIMBER program is to provide funding opportunities to quickly replace older, heavy-duty log trucks earlier than would otherwise be required by regulation. Fleet owners registered for the Log Truck Phase-In option, the NOx-Exempt Area extension, or the Small Fleet option may be eligible to receive funds for the purchase of replacement trucks that have 2010 or newer engines. Truck owners can be based anywhere in California and get applications from one of the participating dealerships to apply for a grant. Click below to locate a participating dealership. Additional participating dealerships will be added as they become available. Applicants must also meet additional eligibility criteria, as stated in the factsheet below, to be eligible for TIMBER Program funding.
