Application Period Now Open for $400 Million Clean School Bus Grant Program

Applications due August 22, 2023

The U.S. Environmental Protection Agency (EPA) is now accepting applications for the 2023 Clean School Bus (CSB) Grant Program opportunity as part of the Bipartisan Infrastructure Law. Under the 2023 CSB Grant Program, the EPA anticipates awarding approximately $400 million in competitive grant funding to eligible applicants for the purchase of zero-emission (ZE) school buses, clean school buses, and ZE charging infrastructure.

The 2023 CSB Notice of Funding Opportunity (NOFO) includes two sub-programs: one for school district and Tribal applicants (School District Sub-program) and one for third-party applicants (Third-Party Sub-program). The EPA will evaluate each sub-program separately under this single NOFO to address the unique needs and concerns of recipients and to encourage broad participation in the CSB grant program.

For this NOFO, the EPA will prioritize applications that replace buses serving high-need local education agencies, Tribal school districts, and rural areas. Additionally, the EPA is committed to ensuring that at least 40% of the program benefits and investments flowing to disadvantaged communities, as laid out in the federal Justice40 Initiative.

Eligible Applicants

  • Local governmental entities that provide bus service, such as public school districts
  • Indian Tribes, Tribal organizations, or Tribal-controlled schools that own buses or provide for service
  • Eligible contractors, including school bus dealers and original equipment manufacturers (OEMs)
  • Nonprofit school transportation associations

Funding Overview

  • Applicants in the School District Sub-program can request funding for 15-50 school buses, and applicants in the Third-Party Sub-program can request funding for 25-100 school buses.
  • Applicants may submit a total of one application per EPA region, but a single application may target multiple fleets, school districts, and/or bus types.
  • ZE fuel type funding levels listed in the table below include combined bus and charging infrastructure. Recipients have flexibility to determine the split between funding for the bus itself and charging infrastructure.

    • Scrap, sell, or donate a 2011 or newer diesel or non-diesel internal combustion engine buses
