## Abstract

The Environmental Protection Agency (EPA) is approving revisions to the Oregon State Implementation Plan (SIP) submitted on March 27, 2023. The submitted changes are designed to strengthen the stationary source permitting rules by eliminating generic plant site emission limits in favor of source-specific and source-category specific limits, updating construction notification requirements, clarifying the use of modeling and monitoring for compliance assurance, and streamlining the application process.
