Oregon Pumps the Brakes on ACT Rules For Model Years ’25 and ’26

Citing “significant uncertainty” in the continued viability of the Advanced Clean Trucks (ACT) mandate, Oregon officials have stopped enforcing some provisions.

Oregon’s Department of Environmental Quality is instructing field agents to “refrain from pursuing enforcement or assessing civil penalties against any manufacturer of medium- and heavy-duty vehicles” for not making sales targets for zero-emissions vehicles (ZEV) in model years 2025 and 2026.

A May 15 memo ordering the change notes that the “current federal administration has created significant uncertainty around ZEV incentives, electric vehicle charging investments, manufacturing and tariffs, each of which threaten a smooth transition to medium- and heavy-duty ZEVs.”

It added that “Congress is considering action to disapprove the waiver granted to the state of California, allowing the enforcement of ACT in Oregon and other states,” along with manufacturer pushback because the sales targets are proving “too difficult to meet.”

Oregon’s non-enforcement of sales targets does come with some caveats. It only applies if the manufacturer:

• Continues to provide internal combustion engine vehicles to Oregon “without imposing restrictions or conditions that would limit their availability;” and
• Makes a good faith-effort to comply with ACT; and
• Keeps submitting the mandatory sales and compliance reports.
