EPA Clean School Bus Program: Is 2026 Funding Still Available?

It's a competitive federal grant, funded by a different law than the one that killed the charger tax credit. Congress created and funded the EPA Clean School Bus (CSB) Program in 2021 through the Infrastructure Investment and Jobs Act, at $5 billion over five years, FY 2022 through FY 2026, according to EPA's own program page. EPA runs it as grants and rebates a district applies for directly, and the money can cover both the bus and the charging infrastructure it needs.That makes it a different program from Section 30C, the federal EV charger tax credit that terminated for property placed in service after June 30, 2026. A tax credit was never the relevant mechanism for a school district anyway, since districts don't carry the tax liability a credit offsets. If your transportation department has heard 'the federal charger credit is gone, so there's no federal money for this,' that statement is merging two separate programs. CSB is the one built for a district's bus-and-charger project, it is administered entirely outside the tax code, and its status is independent of what happened to 30C.

EPA will not award any funds under the 2024 CSB Rebate Program. That is the agency's own language from its February 19, 2026 announcement of a 'path forward' for the program: EPA states it will not award funds for the 2024 round, and 'thanks applicants for their interest' while directing them toward the grant round it is building for 2026 instead.If your district submitted a 2024 application, nothing about it carries forward automatically. EPA's own wording points applicants toward applying again once the new opportunity is posted, not toward an existing application being honored or held in reserve.That cancellation sits on top of an earlier signal in the same direction. Before the February announcement, EPA had already stopped pulling names from the 2022 and 2023 CSB Rebates waitlists, stating on its awards page that remaining funds from those rounds would be 'rolled into future funding opportunities' rather than used to work down the existing waitlist.

As of this check, EPA has closed the public comment period on its restructuring proposal and has not yet published the new grant notice. The comment period ran 45 days, included an informational webinar on March 3, 2026, and closed April 6, 2026, per EPA's program page.The restructuring's biggest substantive change is fuel eligibility. EPA's February 19, 2026 announcement states that compressed natural gas, liquefied natural gas, propane, hydrogen and biofuels 'have always' been allowed under the program's authorizing law, but that the prior administration 'intentionally limited their availability' to electric buses in practice. The 2026 round is being built to fund all of those fuel types, not electric-only, so a proposal scoped as electric-or-nothing is scoping to the old rules.On timing, EPA's language is deliberately open-ended: the agency states only that it will provide additional information on the new grant funding opportunity 'later in 2026.' There is no calendar date, no month, and no committed quarter. Treat that sentence as the actual state of the program, not as a placeholder for a date someone forgot to fill in, and re-check EPA's own page before you build a board presentation around it.

Build the paperwork a grant reviewer will ask for regardless of when EPA's notice lands, because none of it depends on EPA's calendar. Four things are worth doing now rather than after the notice posts.Refresh your fleet inventory and route data. Whatever scoring criteria the 2026 NOFO uses, a current count of buses by age, route mileage and idle windows is the input every version of this program has needed, and it is the same work that sizes a depot's electrical design regardless of which grant pays for it.Start the utility conversation now, not after an award. A load letter to your utility describing the eventual charging build takes weeks to get answered and does not require a grant in hand to send. If your service or a transformer upgrade has a long lead time, that lead time is running whether or not you have funding yet.Decide your fuel mix with the widened eligibility in mind. A district that assumed electric-only under the old program now has propane, CNG and hydrogen as sourced options under the same law, and that decision changes both the equipment you're scoping and the charging infrastructure question entirely for non-electric fuels.Line up your budget calendar against 'later in 2026,' not against a fixed date. A district that only budgets on an annual cycle should treat this as an unscheduled opportunity that could land in any quarter, and should have board approval ready to move quickly once a real deadline exists, rather than waiting for the notice to start that internal process.
