Grant Program

DENR Announces Round 14

The South Dakota Department of Environment and Natural Resources (DENR) announces Round 14 of funding under the South Dakota Clean Diesel Grant Program. There is approximately $507,000 of Diesel Emissions Reduction Act (DERA) funds, $338,000 of VW category 10 DERA funds, and additional VW category 2 bus funds available for the projects. *Note - a project funded with DERA funds cannot also be funded with any other federal funds unless expressly allowed by the other federal program.

The program provides rebates to assist in purchasing new buses to replace old, high-emitting diesel buses. The primary goals of the programs are to reduce your school children's exposure to both fine particulate and smog-forming pollution and to facilitate the improvement and protection of the ambient air quality throughout South Dakota.

The South Dakota programs will provide rebates to help public schools, non-public schools, state special schools, other educational programs, shuttle or transit system providers, and school bus contractors purchase new buses to replace old, high-emitting, diesel buses. Total rebate per replacement bus will be up to 25% of the purchase price of a new bus with an engine certified to EPA emission standards, 35% of the purchase price of a new bus with an engine certified to meet CARB's Low-NOx standards, or 45% of the purchase price of a zero tailpipe emissions bus. DENR intends to award funds to as many eligible applicants throughout the state as possible.
