State Program Updated for Round Ten

You are invited to apply for funding from the South Dakota Clean Diesel Grant Program (Program). This year there will be $223,801 available for funding. The Program provides funds as rebates for the purchase of a new public school bus to replace an old, high-emitting diesel public school bus. The primary goal of the Program is to reduce your school children’s exposure to both fine particulate and smog-forming pollution. SD DENR provides the rebates and administers the Program.


Eligibility for the Program includes any SD public school district that directly provides transportation services for SD public schools. Total rebate per replacement bus will be up to 25% of the purchase price of a 2017 engine model year or newer engine certified to EPA emission stardards, 35% of the purchase price of a 2017 engine model year or newer engine certified to meet CARB’s Low-NOx Standards, or 45% of the purchase price of an all-electric bus.  Preference will be given to any SD public school district that has not received a replacement bus in a previous round. Replacement bus funding will be awarded to replace older buses first.  DENR intends to award funds to as many eligible applicants throughout the state of South Dakota as possible. 

Note: Funds cannot be used for replacements that would have occurred through normal attrition/fleet turnover within three years of the project start date.Bus purchases must not occur before school districts execute an agreement with DENR.
