Connecticut Clean School Bus Program

The Environmental Protection Agency's (EPA) Clean School Bus (CSB) Rebates Program provides funding to replace existing school buses with zero-emission vehicle (ZEV) and low-emission models. With funding from the 2021 Infrastructure Investment and Jobs Act, Public Law 117-58 (Bipartisan Infrastructure Law, "BIL"), the EPA CSB Rebates Program has increased funding by $5 billion over the next five years (fiscal years 2022-2026).  In addition to offering rebates for school bus replacement, the EPA CSB Rebates Program provides a limited amount of funding for infrastructure upgrades necessary to install charging equipment for the buses.

Additionally, Section 13 of Public Act No. 22-25 authorizes to establish a grant program to provide matching funds necessary for municipalities, school districts and school bus operators to submit federal grant applications, in order to and electric vehicle charging infrastructure. This supplemental grant program is intended to pay for a portion of the incremental cost of zero-emission school buses not covered by EPA funding. The DEEP program will also provide supplemental grants to EPA CSB Rebates Program awardees for infrastructure upgrades.

2023 EPA Clean School Bus Program Grants

On April 24, 2023, EPA announced the 2023 Clean School Bus Program Grants to fund electric, propane, and Compressed Natural Gas (CNG) buses that will produce either zero or low tailpipe emissions compared to their older diesel predecessors. Eligible applicants for this funding opportunity are (1) state and local governmental entities that provide bus service; (2) public charter school districts, (3) Indian Tribes, Tribal organizations, or Tribally controlled schools, (4) nonprofit school transportation associations, and (5) eligible contractors (including OEMs, dealers, school bus service providers, and private bus fleets).

EPA will provide a combined funding amount to cover both bus and infrastructure costs for all awardees requesting electric school buses. EPA is prioritizing applications that will replace buses serving high-need local education agencies, Tribal school districts funded by the Bureau of Indian Affairs or those receiving basic support payments for students living on Tribal land, and rural areas (Priority Districts).

Note: The deadline for submitting an application package is August 22, 2023, at 11:59PM (ET).
