## Abstract

The Environmental Protection Agency (EPA) is approving the removal of outdated rules in the Code of Federal Regulations (CFR) for the State of Oregon because they are duplicative or obsolete. Removal of such material from the air program subparts is designed to improve cost effectiveness and usability of the CFR. The EPA is also approving non-substantive revisions to reflect updated citations and correcting a typographical error. This final action makes no substantive changes to the Oregon State Implementation Plan and imposes no new requirements.
