Air Plan Approval; Oregon Department of Environmental Quality; Emission Standards and Controls for Sources Emitting Gasoline Vapors

What it does

The Environmental Protection Agency (EPA) proposes to approve a revision to the Oregon State Implementation Plan (SIP) submitted by the Oregon Department of Environmental Quality (ODEQ) on December 17, 2025, for the Portland and Salem/Keizer, Oregon 1979 1-hour ozone maintenance areas. The proposed revision updates ODEQ's requirements in the SIP for Stages I and II vapor recovery systems at gasoline dispensing facilities including: decommissioning existing Stage II systems incompatible with onboard refueling vapor recovery systems; allowing removal from service of Stage II vapor recovery equipment compatible with onboard refueling vapor recovery; and removing the requirement for Stage II vapor recovery at new installations. The proposed revisions also include more widespread adoption of Stage I Enhanced Vapor Recovery, Stage I vapor balance, and enhanced conventional nozzles, among other changes. The EPA is proposing to find that ODEQ's demonstration to remove Stage II requirements is consistent with the Clean Air Act and the EPA's guidance.
