Heavy-Duty Engine and Vehicle Omnibus Rule Update 2024

Proposed rule

Rulemaking contact: Eric Feeley, 503-915-2798

DEQ is conducting this rulemaking to adopt California Air Resources Board amendments to heavy-duty engine and vehicle exhaust emission standards to maintain identicality with CARB rules for new medium- and heavy-duty vehicles sold in Oregon. This rulemaking will also consider permanent adoption of a 1-year implementation delay which will replace the temporary rule adopted by the EQC on Nov. 16, 2023. This action will provide manufacturers and buyers compliance certainty and add additional flexibilities to the legacy engine sales allowances for engine model year 2025 and 2026.

DEQ plans to:

  • Hold an advisory committee meeting March/April 2024
  • Publish the notice of rulemaking and open the public comment period in April/May 2024
  • Hold a public hearing in May 2024

In convening this committee, DEQ selected a committee that was large enough to provide diverse perspectives and represent affected parties and stakeholders, while allowing opportunity for members to engage.  Advisory committee members will review proposed rules and provide feedback on potential fiscal, economic, and racial equity impacts.
