Abstract
EPA is taking direct final action to approve a redesignation request and a State Implementation Plan (SIP) revision submitted by the State of Oregon. On August 9, 2007 the State of Oregon submitted a request to EPA that the Salem carbon monoxide (CO) nonattainment area be redesignated to attainment for the CO National Ambient Air Quality Standard (NAAQS) and concurrently submitted a maintenance plan that provides for continued attainment of the CO NAAQS. The Salem CO nonattainment area has not violated the 8-hour CO NAAQS since 1985.
