2019 Clean Air Grants for On-Road Trucks and Buses

Santa Barbara County Air Pollution Control District (District) has funding opportunities for a variety of on-road vehicle replacement, repower, and expansion projects. Grant funds are calculated based on the amount of pollutant emissions the replacement project will reduce. For commercial trucks and buses, typical grant amounts cover 5% to 15% of the new vehicle cost.

  • Grant funds are limited and available on a first come, first served basis until all funds have been committed
  • Projects that operate in a Low income Community as defined by AB 1550 will be prioritized for funding.  The AB 1550 map can be viewed at
  • Projects that use zero emission technology will be prioritized for funding.
  • The District may use discretion to distribute funds equitably throughout the county.

Eligible Vehicles:

  • Light-duty commercial trucks and buses (14,001-26,000 GVWR) with engine model years 2007 to 2009 only
  • Heavy-duty commercial trucks and buses (>26,001 GVWR) with engine model years 2005 to 2009 only
  • Commercial trucks and buses currently operating under a CARB exemption (Low Mileage Exemption, NOx Area Exemption, Agricultural Vehicle Exemption etc.)
