Colorado Clean Diesel Program

School Bus Retrofits – No cost to school districts!!

Diesel Emissions and Health

Diesel exhaust contributes to respiratory and cardiovascular diseases, including lung cancer. Toxic emissions from diesel school bus tailpipes and crankcases pollute bus interiors as well as outdoor air. Bus riders and drivers may be exposed to these pollutants for extended periods. Children with their developing lungs and higher respiratory rates are especially vulnerable.

Clean Diesel Retrofit

To reduce toxics exposures, the Colorado Clean Diesel Program retrofits school buses with proven emission reduction technology, including diesel oxidation catalysts, engine pre-heaters, and closed crankcase filtration systems. The engine pre-heaters result in greatly-reduced engine idling, which also saves fuel.

Diesel engine experts from the Colorado Air Pollution Control Division provide follow-up service to ensure that emissions reduction equipment is working properly.

Funding

Program funding is mainly from the U.S. Environmental Protection Agency via Congress’s Diesel Emission Reduction Act (DERA).

Retrofit services are provided to school districts depending on (1) funding availability (2) local air quality issues, (3) vehicle age and configuration, and (4) the Air Pollution Control Division's  resources.

The air division provides idling reduction information and tools to fleet management staff, as well as to students and parent-teacher organizations if desired.
