Description
Reducing Diesel Emissions for a Healthier Tennessee (RDE4HT) uses Tennessee’s allocation of EPA Diesel Emissions Reduction Act funding to reduce diesel-related emissions statewide. The Tennessee Department of Environment and Conservation partners with the East Tennessee Clean Fuels Coalition (ETCleanFuels) to administer the rebate program.
Supported projects include replacement of older diesel vehicles and engines, clean alternative-fuel conversions, and verified idle-reduction technologies. Eligible equipment includes school buses, Class 5–8 trucks, Class 5+ transit buses, and nonroad equipment used in construction, cargo handling, agriculture, mining, or energy production. Truck-stop electrification (TSE) and electric transport refrigeration units (eTRUs) allow cab and trailer equipment to use electricity instead of diesel. Alternative-fuel and electric projects receive priority over diesel replacements.
