Air Plan Approval; Oregon; Update to Materials Incorporated by Reference

The Environmental Protection Agency (EPA) is updating materials incorporated by reference (IBR) into the Oregon State Implementation Plan (SIP). The regulations affected by this update were previously submitted by the Oregon Department of Environmental Quality (ODEQ) and approved by the EPA. In this action the EPA is also notifying the public of corrections to typographical errors and rearranging the contents for clarity. In addition, the EPA is removing duplicative rules in the Code of Federal Regulations (CFR) for the State of Oregon to improve cost effectiveness and usability of the CFR. This update makes no substantive changes to the Oregon SIP and imposes no new requirements. This update affects the materials that are available for public inspection at the National Archives and Records Administration (NARA) and the EPA Regional Office.
