Reducing Diesel Emissions for a Healthier Tennessee (RDE4HT)

rde4htEast Tennessee Clean Fuels Coalition’s “Reducing Diesel Emissions for a Healthier Tennessee” Rebate Program is making grant funding available in Tennessee to replace older, diesel vehicles with a) new alternative fuel vehicles (AFVs) that can run on propane, compressed natural gas (CNG), electricity, or that are hybrids, or b) new diesel vehicles. Funding can now also be requested for efforts towards replacing engines in older diesel vehicles with new alternative-fueled or diesel engines, converting OEM diesel vehicles to run on alternative fuels, and the addition of Truck Stop Electrification (TSE, and similar) equipment at Tennessee-based Travel Centers.

This funding is EPA Diesel Emissions Reductions Act, or DERA, funding that is provided to states to reduce diesel emissions. The Tennessee Department of Environment and Conservation (TDEC) oversees Tennessee’s state EPA funding and is partnering with the East Tennessee Clean Fuels Coalition (ETCleanFuels) to manage the Rebate Program and funding and direct it into efforts that reduce diesel emissions in Tennessee from Memphis to Mountain City. ETCleanFuels will collaborate with the Middle-West Tennessee Clean Fuels Coalition in making the funding available to fleets across the entire state. “Tennessee Clean Fuels” is an overarching name for both Clean Cities coalitions working together on projects for all Tennesseans and Tennessee fleets.

Public or private entities in Tennessee may apply for funding.

This can include (but is not limited to) equipment utilized at public travel centers and private trucking fleet terminals.


  • Any one entity may apply for a maximum of 15 new vehicles or engine replacements.
  • The new vehicle(s) that are purchased must be kept in service for a minimum of three (3) years and be used on similar routes with a similar number of miles per year as the older vehicles that are being replaced.RDE4HT benefits
  • The applicant must provide with their proposal to ETCleanFuels one quote for each new vehicle or engine for which funding is being requested. For engines, the quote should include costs for equipment and labor.

  • Vehicle/Engine Age. Please see the table on p. 4 in the RFP for specifics about which old vehicle years are allowable for replacement.
  • Vehicle replacements – Funding can cover 25% – 45% of the total new vehicle costs depending on emissions reductions and the type of fuel being used in the new vehicle. Please see the breakdown on p. 4 in the RFP for more information.
  • Engine replacements – Funding can cover 40% – 60% of the cost (equipment and labor) of replacing a diesel engine; please see the breakdown on p. 4 in the RFP for clarification.
  • Alternative fuel conversions – A maximum of 40% of the cost (equipment and labor) of an eligible certified or compliant clean alternative fuel conversion.
  • PRIORITY. This is new in 2019-2020, and applies across all applications. The following priority will be assigned to funding projects this year:
    1. Alternative-fuel school buses
    2. Other alternative-fuel vehicles/engines
    3. New diesel school buses
    4. Other, new diesel vehicles/engines


Public and private locations that would like to install TSE, electric TRUs or “reefers” (trailer refrigeration
units, or eTRU when able to run off of Shorepower-type electricity). This can include (but is not limited to) equipment utilized at public travel centers and private trucking fleet terminals.

  • No more than 30% of the total cost to purchase and install equipment that is used to provide heating, cooling and/or electric power to the tractor cab or trailer shall be covered.
  • For eTRU units, no more than 25% of the total cost of a new eTRU system or entire trailer with an attached eTRU system shall be covered.
  • There is no limit on the number of spaces or trucks/trailers that may be applied for.
  • The funding can go towards a) the electrification infrastructure that will allow the diesel-using equipment on the tractor or trailer to turn off and use electricity instead, and b) a trailer or the equipment that would be installed on a trailer to operate a cooling system on electricity in lieu of diesel. This includes necessary installation costs. Please note that applications that request funding for the eTRU that goes on the trailer (and potentially the new trailer too) must be approved by EPA.
  • The funding cannot pay for APUs for tractors.
