Diesel Emissions Identification 2023

Adopted rule

Administrative Order No.: DEQ-7-2023
Filed: July 20, 2023
Effective: Aug. 1, 2023
See Oregon Bulletin, August 2023

Rulemaking contact: Amina Foster, 503-887-7170  

In 2019, the Oregon Legislature passed HB 2007, which directs DEQ to adopt a program, by rule, that would allow for owners and operators of diesel-powered construction equipment to demonstrate the emissions profile of each piece of equipment, and in turn receive emission control labels from DEQ that would reflect those profiles. These labels would be placed on the outside of the equipment, which would make it easier for interested parties to identify key characteristics of the engines inside of the equipment. 

The purpose of this rule is to provide an easy way for owner/operators of diesel-powered construction equipment to identify the emissions profile for each piece of equipment at a construction site. The voluntary emission control labels that this program generates can be used to demonstrate compliance with state and local agencies that have requirements to limit emissions from construction equipment used on their projects.

DEQ is convening an advisory committee to review the fiscal impacts related to the proposed rules. In convening this committee, DEQ has appointed members that reflect the range of entities that are both directly and indirectly affected by proposed changes to the rules.
