As diesel emission-reducing technology has improved over the years, Oregon is still seeing significant pollution from older on-road diesel engines. One method to reduce these harmful emissions includes the installation of appropriate aftermarket retrofit technology. The 2019 Oregon Legislature responded to diesel emission concerns and passed House Bill 2007 to reduce diesel emissions across the state. The bill established deadlines, after which certain older model diesel engine vehicles cannot be titled or registered by the Department of Motor Vehicles or the Commerce and Compliance Division in Clackamas, Multnomah, and Washington counties unless equipped with approved retrofit technology and certified by DEQ. The two vehicle weight classifications categorized in HB 2007 include:
In preparation of submitting the online application, there are several steps vehicle owners will need to complete. Below is a checklist and summary of the application process.
After completion of the vehicle retrofit installation, Oregon DEQ requires the following documents to be ready prior to submitting the application. The Signature of Attestation will need to be completed and signed by the registered owner or authorized representative. The installer will also need to sign the Installer Certification Section. The other documents listed below should be provided by the installer.
Please ensure the following requirements have been prepared by the authorized installer:

The Environmental Protection Agency, and California's Air Resource Board, maintain lists of currently verified retrofit technologies for on-road diesel engines, proven to achieve at least an 85% reduction in diesel particulate matter. Currently verified EPA or CARB retrofit technologies, otherwise known as diesel particulate filter or DPF systems, may qualify as Approved Retrofit Technology for Oregon's Retrofit Compliance Program. To meet the criteria for Approved Retrofit Technology, DEQ will need to verify that the technology meets the following:

HB 2007 (2019) authorized DEQ's Diesel Emissions Mitigation Grant Program to provide grant funding, subject to availability, to support the purchase of retrofit systems, as well as cleaner burning engines and diesel equipment replacements. Vehicle owners who apply and are awarded the grant funding, will be eligible for up to 100% of the retrofit technology cost. DEQ intends to have approximately $8 million available each year beginning in 2021 with a target of providing at least five years of funding based on available revenue.
