The application submittal period is open from April 1, 2020 through June 30, 2020, 5 PM. Please submit original hard copy applications. Faxed or emailed applications will not be considered for funding.

Additional criteria can be found in the 2017 CMP Guidelines, Chapter 4: On-Road Heavy Duty Vehicles.

  • The existing bus must be in operational condition and have operated in the school District’s fleet for at least two years.
  • For school bus electric conversions, the baseline vehicle chassis must be ten years old or newer. CHP requires engineering plans, certified by a California licensed engineer, to be able to safety certify the school bus.
