Oklahoma Clean Diesel (DERA) Program

< back to Air Funding Opportunities

The Clean Diesel program has allowed many entities across the state to replace their old diesel vehicles, thus improving the air quality for the children, environment, and citizens of Oklahoma. More than 43 school districts have been able to replace and/or retrofit more than 287 diesel school buses. This EPA-sponsored program is funded under the federal Diesel Emissions Reduction Act (DERA); Volkswagen Settlement funds are used to match federal funds.
