APCD - On-Road Grants 2017


The fleet modernization program provides incentives to replace old high pollution medium and heavy duty vehicles with newer, lower emission replacement vehicles, providing real emission benefits earlier than would have been expected attrition or regulation implementation.

Eligibility Criteria

  • Existing vehicle must have an engine of model year 2006 or older. Existing old school buses may have an engine of any model year.
  • Existing vehicle must meet the criteria for either a Medium-Heavy Duty or Heavy-Heavy Duty vehicle as defined in the 2011 CMP Guidelines.
  • The existing vehicle must be in operational condition, currently registered in California for the past 24 months and in compliance with federal, state and local regulations.

Application Form



The Truck Improvement/Modernization Benefiting Emission Reductions (TIMBER) Program provides a streamlined voucher funding option to reduce emissions by replacing 2006 or older model diesel engine log trucks with 2010 or newer model diesel engine log trucks. When used to offset vehicle replacement costs, qualifying projects are eligible for up to $60,000.

More information about the TIMBER program can be found at California Air Resources Board’s TIMBER website.
