## Abstract

In reviewing past State Implementation Plan (SIP) actions, the Washington Department of Ecology (Ecology) and the Environmental Protection Agency (EPA) discovered minor typographical errors related to the EPA's previous approvals of Chapter 173-400 Washington Administrative Code, General Regulations for Air Pollution Sources. The EPA is taking direct final action to correct these errors. This direct final action makes no substantive changes to the SIP and imposes no new requirements.
