Program objective
Title XI, Section 71101 of the Infrastructure Investment and Jobs Act (IIJA or The Bipartisan Infrastructure Law or (BIL)), Public Law 117-58 amended section 741 of the Energy Policy Act of 2005 (42 U.S.C. 16091) to authorize the EPA’S Clean School Bus (CSB) Program to award grants, contracts, and rebates for the replacement of existing school buses with clean school buses. IIJA appropriates $ 5 billion for the program over five Federal fiscal years (FY 22-26). The objective of this assistance is, to the maximum extent practicable, achieve nationwide deployment of clean school buses and zero-emission school buses and to ensure a broad geographic distribution of awards. The CSB Program will fund the replacement of existing school buses with cleaner buses that result in better air quality on the bus, in bus loading areas, and throughout the communities in which they operate. The Clean School Bus Program works to reduce pollution emitted from existing school buses by replacing them with cleaner school buses. Priority is given to projects which propose to replace buses that serve high-need local education agencies; rural school districts; Bureau of Indian Affairs-funded school districts; and school districts receiving basic support payments for children who reside on Indian land.
