Clean Diesel Grants

There are a variety of grant programs available to owners of older diesel equipment or vehicles who are interested in retrofits, repowers, or replacements. The amount of the award per equipment/vehicle depends on the program, the type of equipment/vehicle, and the type of action proposed (retrofit, repower or replacement).  Often, grant programs fully fund emission control device retrofits, but will only cover a percentage of the cost associated with an engine repower or equipment/vehicle replacement. 

Check the following links for more information about federal and State of Oregon grants related to clean diesel.
