## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve a carbon monoxide Limited Maintenance Plan (LMP) for Grants Pass, submitted by the State of Oregon on April 22, 2015 as a revision to its State Implementation Plan (SIP). In accordance with the requirements of the Clean Air Act (CAA), the EPA is approving this SIP revision because it demonstrates that Grants Pass will continue to meet the carbon monoxide National Ambient Air Quality Standards (NAAQS) for a second 10-year period beyond re-designation, through 2025.
