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.

Program details & compliance

Description

School buses in the United States travel more than 4 billion miles each year, providing the safest transportation to and from school for more than 25 million American children every day. 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.

Mission Categories

Primary: Air Pollution Control

Use of Funds

Allowed Uses

Grants, contracts, and rebates can be made available to eligible recipients to replace existing school buses with either clean school buses or zero-emission school buses. A “clean school bus” is a school bus that reduces emissions and is operated entirely or in part using an alternative fuel or is a zero-emission school bus. A “zero-emission school bus” is a school bus that produces zero exhaust emission of any air pollutant and any greenhouse gas. Half of the total funding available annually is dedicated to zero-emission school buses while the other half is for clean school buses.

Matching Requirements

EPA may include voluntary and mandatory matching requirements. These requirements may vary based on whether the eligible recipient’s application qualifies for prioritizations listed in the statute.
