EPA Clean School Bus Program: 2024 Rebate Archive and 2026 Funding Status

This page is a historical reference, not an open application listing. The U.S. Environmental Protection Agency (EPA) closed the 2024 Clean School Bus Rebate application period on January 14, 2025 at 4:00 PM ET. EPA later announced that it would not award funds as part of the 2024 Clean School Bus Rebate Program. The current EPA program hub says the agency is developing a new 2026 Clean School Bus grant funding opportunity, but it has not published the new Notice of Funding Opportunity (NOFO), application window, deadline, award amount, or eligibility rules.

The official pages to watch are:

Do not treat the archived 2024 date as a current deadline. Do not submit a new application through the old rebate materials. When EPA publishes the 2026 grant NOFO, read that document for the controlling rules; the future program may differ from the 2024 rebate in fuel choices, applicant categories, award sizes, and application steps.

Current status in plain language

EPA’s program hub says the Request for Information (RFI) comment period for the 2026 funding opportunity closed on April 6, 2026. EPA says the comments will inform development of a new round of Clean School Bus grant funding and that additional information will be provided later in 2026. That is a program-development notice, not an open grant competition.

EPA’s February 19, 2026 announcement also says the agency is revamping the program and will provide more details on the 2026 grants and eligibility requirements through a future NOFO. The same announcement says EPA will not be awarding funds as part of the 2024 CSB Rebate Program. Those statements change how this opportunity should be presented: there is no verified application route today, and there is no responsible way to invent a 2026 deadline or promise that the old rebate table will carry forward.

The amount and eligibility details below describe the closed 2024 rebate only. They are included so a district can understand old records, past awards, and preparation work without mistaking them for 2026 rules.

What the 2024 rebate covered

The 2024 Clean School Bus Rebate was designed to replace existing school buses with new clean or zero-emission school buses. The published replacement technologies were battery-electric, compressed natural gas (CNG), and propane. EPA also allowed eligible electric-bus infrastructure from the electrical meter to the charging port. Costs for work in front of the electrical meter were excluded from the published infrastructure scope.

The 2024 page listed up to $965 million in anticipated total rebate funding, subject to adjustment. A district applying directly could request replacement of up to 50 buses in one application. The maximum amount per bus depended on the replacement fuel type, bus class, and whether the served school district met EPA prioritization criteria. These were ceilings, not guaranteed awards, and EPA has since stated that it will not award funds under that 2024 rebate program.

For the closed cycle, the published per-bus table included:

Prioritized districts: up to $325,000 for Class 7+ zero-emission buses, $245,000 for Class 3–6 zero-emission buses, $45,000 for Class 7+ CNG, $30,000 for Class 3–6 CNG, $35,000 for Class 7+ propane, and $30,000 for Class 3–6 propane.
Other eligible districts: up to $170,000 for Class 7+ zero-emission buses, $115,000 for Class 3–6 zero-emission buses, $30,000 for Class 7+ CNG, $20,000 for Class 3–6 CNG, $25,000 for Class 7+ propane, and $20,000 for Class 3–6 propane.

Applicants could request up to $20,000 per bus for an ADA-compliant replacement bus with a wheelchair lift. Applicants in Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands could also receive up to $20,000 per bus for increased shipping costs if selected. None of these historical figures should be copied into a 2026 budget until EPA publishes the new grant rules.

Historical eligibility for the closed 2024 cycle

The 2024 eligible applicant categories were specific. They included local or state governmental entities responsible for providing school bus service to public school systems or for purchasing, leasing, licensing, or contracting for school bus service. Public charter school districts with responsibility for school bus service were included. Regional Education Service Agencies and Joint Transportation Agencies could apply when they had an NCES ID specific to the RESA or JTA.

Tribal applicants included Indian Tribes, Tribal Organizations, and Tribally Controlled Schools responsible for providing bus service for a Bureau of Indian Education-funded school or for purchasing, leasing, licensing, or contracting for school bus service. EPA also allowed eligible contractors, including qualifying for-profit, not-for-profit, and nonprofit entities, to sell, lease, license, or contract for clean or zero-emission school buses or related charging or fueling infrastructure, or to arrange financing for those transactions. School bus dealers, original equipment manufacturers, school bus service providers, private school bus fleets, and nonprofit school transportation associations could qualify when they met the contractor rules.

The 2024 bus rules were also detailed. An existing replacement candidate generally had to be a model-year 2010 or older diesel school bus, have a GVWR of at least 10,001 pounds, be operational when the application was submitted, and have served a public school district at least three days per week on average during the 2023/2024 school year. EPA described limited substitution paths when a fleet had no eligible 2010-or-older diesel bus available for a zero-emission replacement. Those paths had different scrap, sale, or donation requirements for older and newer internal-combustion buses.

New replacement buses for the 2024 rebate had to be new battery-electric, CNG, or propane vehicles, model year 2023 or newer, with a GVWR of at least 10,001 pounds and applicable Federal Motor Vehicle Safety Standards certification. Conversions after first retail sale were not eligible. The buses could not be ordered before official selection, had to be purchased rather than leased or leased-to-own, and generally had to serve the school district on the application for five years after delivery. EPA also required appropriate maintenance, operation, insurance, registration, and charging or fueling practices.

Those rules are historical. EPA has not said that the same applicant classes, bus model years, technologies, five-year service rule, or funding table will govern the 2026 grant opportunity.

What application steps existed, and what to do now

For the closed 2024 rebate, applicants first reviewed the program guide and confirmed their applicant category. They needed an active organization registration in SAM.gov, not merely a personal SAM.gov account. The registered entity’s points of contact had to use matching login.gov email details to access the EPA dashboard. The primary SAM.gov entity listed on the application was also the entity EPA could pay if the application had been selected.

The application preparation package included the organization’s 12-character UEI and, where relevant, the four-digit Electronic Funds Transfer Indicator. Applicants prepared the served school district’s seven-character NCES District ID, district contact information, and information about any private fleet involved. For each existing bus, EPA asked for the 17-character VIN, manufacturer, model, fuel type, model year, estimated average annual mileage and fuel consumption, GVWR, and scans of titles or required registrations. The application also required information about the proposed replacement bus, including estimated GVWR and fuel type, plus prioritization evidence or self-certification where applicable.

The 2024 process then used the EPA applicant dashboard for submission and review. Applicants could be asked to answer eligibility questions or provide clarifying information. Selected applicants used the same dashboard for payment requests based on awarded funding and purchase orders, followed by closeout after delivery, infrastructure installation where applicable, and replacement of the old buses.

That is not a current application procedure. The 2024 application form stopped accepting applications on January 14, 2025, and EPA has said it will not award funds under the 2024 rebate. The online forms page now remains useful for existing records and historical program documentation, but it does not provide a live 2026 application. A district seeking future support should:

Monitor the EPA Clean School Bus Program hub and sign up for EPA program updates.
Wait for the 2026 grant NOFO rather than relying on the 2024 rebate guide.
Read the new NOFO’s applicant, vehicle, fuel, cost, prioritization, and submission rules before deciding whether to prepare an application.
Keep fleet records, procurement authority, SAM.gov information, and district contacts current so the organization can respond when a real window opens.
Confirm any future deadline and required forms from the new EPA notice itself.

Useful preparation without assuming future rules

Fleet managers can still do sensible preparation. Maintain a VIN-level inventory with model year, GVWR, fuel type, operating condition, service history, ownership, and registration records. Keep district service relationships and contractor authority documented. Separate estimates for bus purchase, charging or fueling infrastructure, utility work, shipping, and accessibility equipment. That work improves internal decision-making, but it does not establish future eligibility.

Before purchasing equipment in anticipation of federal support, obtain the new NOFO and check its ordering and award rules. The 2024 guidance barred ordering replacement buses before official selection and required that total CSB funds and other eligible external funds not exceed the replacement-bus cost. A later grant may use different controls, so the old rule is a planning warning rather than a current promise.

For electric-bus planning, map utility service, depot space, charging locations, route length, cold-weather needs, maintenance capacity, and meter-to-charger construction. For CNG or propane planning, document fueling access, safety procedures, maintenance capability, and vehicle availability. These are operational questions, not evidence that EPA will fund a particular technology in 2026.

FAQ

Can I apply to the 2024 rebate now?

No. EPA says the 2024 rebate stopped accepting applications on January 14, 2025.

Is there a 2026 deadline?

No deadline has been published. EPA says the RFI comment period closed April 6, 2026 and that more information about a new grant opportunity will follow later in 2026.

Has EPA announced the 2026 award amount?

No. The $325,000 figure belongs to the closed 2024 rebate’s prioritized Class 7+ zero-emission category and is not a 2026 grant promise.

Do the 2024 eligibility rules still apply?

They describe the closed rebate only. EPA says the 2026 grant’s eligibility requirements will be provided through a future NOFO.

What should an existing 2024 applicant do?

Use the official EPA forms and contact channels for the status of an existing record. Do not assume that an old application will become a 2026 grant application; EPA’s February 19 announcement says it will not award funds as part of the 2024 rebate.

Where can technical questions go?

EPA’s program materials list [email protected] for program questions and [email protected] for technical assistance on topics such as bus basics, charging, utility connections, routing, and maintenance. Confirm current contact instructions on the EPA site before sending a request.

Official documents

The correct conclusion for this page is straightforward: the 2024 rebate is closed and remains useful as an archive of its published rules; the 2026 grant is under development and has no announced application date, amount, or eligibility framework. Check the EPA hub for the future NOFO before treating this opportunity as actionable.
