Air Quality State Implementation Plans; Approvals and Promulgations: Oregon; Oregon Department of Environmental Quality; Emission Standards and Controls for Sources Emitting Gasoline Vapors

What it does

• •Proposes to approve Oregon's updated State Implementation Plan (SIP) revision submitted December 17, 2025, for Portland and Salem/Keizer ozone maintenance areas.
• •Removes the requirement for Stage II vapor recovery systems at gasoline dispensing facilities and allows decommissioning of existing incompatible systems.
• •Adds alternative VOC controls including Stage I Enhanced Vapor Recovery, Stage I Vapor Balance Systems, and Enhanced Conventional nozzles.
• •Incorporates by reference Oregon's Division 244 and Division 216 rules (effective March 25, 2024) into the federal SIP.

Why it matters

• •Reflects EPA's 2012 determination that onboard refueling vapor recovery (ORVR) systems are in widespread use and provide equivalent emission reductions to Stage II systems, making Stage II requirements obsolete.
• •Addresses ground-level ozone, a criteria air pollutant harmful to human health and the respiratory system, by maintaining VOC emission controls through alternative technologies.
• •Ensures Oregon's air quality plan complies with the Clean Air Act and does not interfere with attainment of National Ambient Air Quality Standards.

Who is affected

• •Gasoline dispensing facilities in the Portland and Salem/Keizer, Oregon ozone maintenance areas.
• •Vehicle owners and the automotive refueling industry in affected Oregon regions.
• •The Oregon Department of Environmental Quality, which administers the updated requirements.

What happens next

The EPA will accept public comments on the proposed approval until December 14, 2026, via the Federal Register docket (EPA-R10-OAR-2026-2972) at regulations.gov.
