## Abstract

EPA is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of Washington. The Washington State Department of Ecology submitted the Vancouver Air Quality Maintenance Area Second 10-year Carbon Monoxide Maintenance Plan on April 25, 2007. In accordance with the requirements of the Federal Clean Air Act (the Act), EPA is approving Washington's revision because the State adequately demonstrates that the Vancouver Air Quality Maintenance Area will maintain air quality standards for carbon monoxide (CO) through the year 2016.
