Published Date: 1/29/2026
Rule
Summary
The EPA just gave a thumbs-up to Lane County’s updated air pollution rules, making them match Oregon’s state standards better. These changes simplify how businesses get permits, focus on specific pollution sources instead of broad limits, and update how construction projects notify the agency. Starting March 2, 2026, local companies and regulators will follow these clearer, smoother rules—no extra costs announced, just cleaner air and easier paperwork!

Source-specific Limits Replace Generic PSELs
If you operate a stationary source in Lane County, Oregon, LRAPA removed generic plant-site emission limits (PSELs) and replaced them with source-specific emission limits as part of the SIP approved by EPA. This change is effective March 2, 2026 and changes how permits set emission limits for individual pieces of equipment or sources.
Updated Construction Notification Rules
If you plan to construct or modify a stationary source in Lane County, LRAPA updated the notice-to-construct, construction approval, and related notification requirements that are now part of the SIP. These updated construction notification rules become effective March 2, 2026.
Permitting Requires Appendix W Modeling
LRAPA rules incorporated into the SIP require air quality modeling to follow appendix W (EPA guidance) and clarify modeling and monitoring used in permitting. This modeling/monitoring clarification is effective March 2, 2026.
Permit Application Process Streamlined
LRAPA revised and streamlined permit application and related procedures (including registration, types of ACDPs, and public notice/issuance procedures) and these revisions are incorporated into the SIP effective March 2, 2026. The changes are intended to align local permitting with State rules.
