Diesel Emissions Identification Program

In July 2023, the Environmental Quality Commission, DEQ’s governing body, adopted rules for the Diesel Emissions Identification Program in the newly created division 269 of the Oregon Administrative Rules. The program fulfills the requirement to create a voluntary emissions control program for nonroad construction equipment that the legislature directed DEQ to implement with HB 2007 (2019) as a part of a larger strategy to reduce diesel emissions in the state of Oregon. 

This program will provide emission control labels for nonroad construction equipment, like excavators and loaders. This rule uses DEQ’s existing authority for adding emission control labels for onroad concrete mixer trucks and dump trucks. These labels can be used to help track fleet compositions for construction projects which can be useful in demonstrating compliance with clean construction contracting standards that other government agencies may have, in addition to clean construction requirements that other entities may have.
