2020 DERA School Bus Rebates Program

Applications Being Accepted
Deadline to Apply - October 30, 2020 (4 p.m. ET)

We are excited to announce a funding opportunity for school bus fleets that serve public schools. EPA’s Office of Transportation and Air Quality is accepting applications nationwide for rebates to assist in replacing older, dirtier diesel school buses with new school buses certified to EPA's cleanest emission standards. EPA anticipates awarding over $10 million in this funding opportunity. Selected applicants that scrap and replace their old diesel buses will receive a rebate of $20,000-$65,000 per bus depending on the fuel type of the replacement bus.

Eligible Entities

  • Regional, state, or tribal agencies including school districts and municipalities; or
  • Private entities that operate school buses under a contract with an entity listed above.
  • Applications are limited to 10 buses. Fleets that own more than 100 buses can submit two applications.

Selection Process
Lottery, with at least one selectee from each state/territory represented in the applicant pool.

Stopping Aftermarket Defeat Devices for Vehicles and Engines

Poster: Emissions Tampering is llegal and pollutes our airTampering with a vehicle's emissions control system is illegal under the Clean Air Act (CAA) and causes excess emissions of nitrogen oxides (NOx), particulate matter (PM), and other pollutants to the air we breathe. The CAA also prohibits manufacturing, selling, offering for sale and installing aftermarket devices which effectively defeat those controls.

EPA's current National Compliance Initiative (NCI) for 2020-2023, "Stopping Aftermarket Defeat Devices for Vehicles and Engines," focuses on stopping the manufacture, sale, and installation of defeat devices on vehicles and engines used on public roads as well as on nonroad vehicles and engines. EPA has found that tampering is widespread. Both EPA and states are concerned that engines whose emissions control devices are missing or not working are harming public health and the environment, and that they may contribute to states failing to achieve air quality standards.

  • EPA to Award up to $73 million for Clean Diesel Projects
    On September 29, at a press conference in Minnesota, U.S. Environmental Protection Agency (EPA) Administrator Andrew Wheeler announced over $73 million in grants and funding expected to be awarded to support numerous clean diesel programs and projects across the country at the state and local level. Over $50 million in Diesel Emissions Reduction Act (DERA) National Grants Program funding is expected to be awarded to implement projects aimed at reducing diesel emissions from the nation’s existing fleet of old, dirty engines and vehicles. Additionally, EPA anticipates providing approximately $23.5 million under DERA’s 2020 State Grants program to 48 states and four territories to implement their own diesel emissions reduction programs.

  • EPA's "Port Emissions Inventory Guidance: Methodologies for Estimating Port-Related and Goods Movement Mobile Source Emissions" is now available.
    This guidance describes the latest, state-of-the-science methodologies for preparing a port-related emissions inventory for six mobile source sectors: ocean-going vessels, harbor craft, recreational marine, cargo handling equipment, onroad vehicles, and rail. This guidance reflects new data sources and model availability, and integrates the lessons learned from practical experience with EPA-Port Everglades Partnership and National Port Strategy Assessment.
