HB 2007 Retrofit Compliance Rulemaking - April 5, 2021

In 2019, the Oregon Legislature passed House Bill 2007 - known as the “Clean Diesel Bill" - authorizing the Environmental Quality Commission of the Oregon Department of Environmental Quality to adopt rules for certification of approved retrofit technologies of diesel engines that power medium-duty and heavy-duty trucks.

The legislation includes prohibitions on registering and titling older diesel engines in Clackamas, Multnomah and Washington counties after specified deadlines, unless they are equipped with retrofit technologies established by the commission or DEQ.
