Abstract
This action finalizes our approval of the State Implementation Plan (SIP) revisions submitted by the Oregon Department of Environmental Quality on January 3, 2005. EPA is approving the State of Oregon's second 10-year carbon monoxide (CO) maintenance plan for the Portland maintenance area. Specifically, EPA is approving the following: Oregon's demonstration that the Portland CO Attainment Area will maintain air quality standards for CO through the year 2017; a revised CO motor vehicle emissions budget for transportation conformity purposes using the MOBILE6.2 emissions model and latest growth and planning assumptions; and revised state implementation plan (SIP) control strategies and contingency measures.
