## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to remove outdated rules in the Code of Federal Regulations (CFR) for the State of Washington because they are unnecessary or obsolete. The EPA is also clarifying regulations to reflect updated citations and more recent air quality monitoring data. This direct final action makes no substantive changes to the State Implementation Plan (SIP) and imposes no new requirements.
