The Missouri Clean Diesel Program strives to improve air quality by reducing diesel emissions from on-road and off-road diesel engines operating in the state.
The Department of Natural Resources actively pursues funding opportunities for Missouri's diesel equipment fleet owners and operators. When opportunities become available, the department will list them on this page as well as any partner websites.

2015 Missouri Clean Diesel Program (Early School Bus Replacement Program)


Through the U.S. Diesel Emission Reduction Act (DERA), the department’s Air Pollution Control Program has received a 2015 grant from the U.S. Environmental Protection Agency to fund the Missouri Clean Diesel Program.
This year, the Missouri Clean Diesel Program targets early replacements for school buses. The Department of Natural Resources conducted a similar program in 2013 and received 20 applications from owners of school buses across the state. Five school districts received awards of up to 25 percent of the cost of new school buses.

These vehicles operate five days a week in highly populated areas. They also congregate in parking lots and depots, which receive disproportionately high amounts of diesel emissions. In addition, by targeting school buses, the Missouri Clean Diesel Program benefits school-age children, who breathe at a faster rate and have respiratory and immune systems that are still developing. Asthma is one of the most common long-term diseases during childhood, and it accounts for more school absenteeism and emergency room visits than any other chronic disease experienced by children. Diesel engines emit particulate matter and precursors of ground-level ozone. Reducing these pollutants can help minimize periods of poor health in children, especially those who have asthma or other chronic respiratory diseases.

According to figures from the U.S. Environmental Protection Agency (EPA), replacing a school bus built in 2000 with a 2015 model would reduce emissions of pollutants by substantial amounts. For instance, carbon monoxide emissions would fall by 61 percent, and emissions of particulate matter would fall by 97 percent. Emissions of other pollutants also would fall by more than 90 percent. Children, families, and school employees obviously will reap health benefits from this program.

The Selection Process

The department’s Air Pollution Control Program has developed a request for applications soliciting early school bus replacement projects through the 2015 Missouri Clean Diesel Program. The program will accept applications for early replacements of school buses through August 31, 2015. All school bus owners and operators with school buses operating in Missouri are eligible to apply for this funding opportunity. The program targets school buses with engines built between 1993 and 2006. If selected, awardees will receive up to 25% of the cost of a new school bus. In order to ensure that the program results in the reduction of harmful emissions, the bus being replaced must be permanently disabled after the new bus is purchased and accepted.

On September 21, 2015, the Air Pollution Control Program will randomly select the awardees. All applications that are determined to be eligible will have an equal chance of being selected. The Air Pollution Control Program expects to select six (6) applicants, which will result in the early replacement of six (6) older, higher-polluting school buses with new buses meeting the latest emission regulations.
