DEQ to open application process soon for 2023 grant funds to replace and retrofit diesel equipment

7 Mar 2023
The Oregon Department of Environmental Quality is providing approximately $8 million in grant funding for diesel equipment owners to replace older and more polluting diesel engines with new, cleaner technologies and exhaust control retrofits. The Diesel Emissions Mitigation Grants program is designed to help address health and environmental impacts from diesel emissions in Oregon.

The application process opens on Monday, April 3, and runs through 5 p.m. (PDT) on Tuesday, June 6, 2023.

Business, government and tribal diesel equipment owners across the state are invited to apply for funding for projects that reduce diesel emissions in Oregon. Visit the DEQ Diesel Emissions Mitigation Grants program web page to:

Owners of medium- and heavy-duty vehicles requiring retrofits under the Diesel Retrofit Compliance Program may also apply for funding to support the installation of diesel particulate filters.

The 2023 application is the only opportunity this year to apply for a Diesel Emissions Mitigation Grant. Award recipients can apply for additional funds in subsequent years.
