Clean Diesel Rebates

2017 School Bus Rebate Application Period is now Closed

The Diesel Emissions Reduction Act of 2010 (PDF)(7 pp, 133 K, January 2011, About PDF) allows EPA to offer rebates in addition to grants to reduce harmful emissions from older, dirtier diesel vehicles. The rebate program has funded vehicle replacements or retrofits for over 600 vehicles to date. Typically, the rebate application period opens in the fall and projects are completed in less than one year.

2017 School Bus Replacement and Retrofit Rebates

School buses travel over four billion miles each year, providing the safest transportation to and from school for more than 25 million American children every day. However, diesel exhaust from these buses has a negative impact on human health, especially for children who have a faster breathing rate than adults and whose lungs are not yet fully developed.

EPA designed this rebate program to encourage school bus fleet turnover so more children can ride buses with the cleanest emissions standards or buses that have been retrofitted to reduce emissions. The 2017 School Bus Rebate Program will provide over $7 million to public and private fleet owners for the replacement or retrofit of older school buses. Up to $1 million of the funding total will be available for retrofit funding requests in the selection process.

  • Retrofits: Buses powered by 1994-2006 model year engines must be retrofitted with a EPA verified Diesel Oxidation Catalyst (DOC) and have the option of adding a verified Closed Crankcase Ventilation (CCV) system and Fuel Operated Heater (FOH). DOC retrofits can qualify for up to $3000, DOC+CCV can qualify for up to $4000, DOC+FOH can qualify for up to $5000, and DOC+CCV+FOH can qualify for up to $6000 to cover parts and installation.
