EPA Tidies Up Oregon's Air Plan Reference Materials

## Summary

The EPA is updating Oregon’s air quality plan by fixing and clarifying some official documents that were already approved. This update makes sure the right materials are on file and easy to find for anyone who wants to check them out. No new costs or deadlines—just a smoother, clearer record for Oregon’s clean air efforts.

## Abstract

The Environmental Protection Agency (EPA) is updating the materials that are incorporated by reference (IBR) into the Oregon State Implementation Plan (SIP). The regulations affected by this update have been previously submitted by Oregon and approved by the EPA. In this final rule, the EPA is also notifying the public of corrections and clarifying changes in the Code of Federal Regulations (CFR) tables that identify the materials incorporated by reference into the Oregon SIP. This update affects the materials that are available for public inspection at the National Archives and Records Administration (NARA) and the EPA Regional Office.
