Approval and Promulgation of State Implementation Plans: Washington

The EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Washington, Department of Ecology (Ecology). These revisions pertain to the maintenance plan prepared by the State of Washington to maintain the 8-hour national ambient air quality standard (NAAQS) for ozone in the Vancouver portion of the Portland/Vancouver Air Quality Maintenance Area (Pdx/Van AQMA). The 110(a)(1) maintenance plan for this area meets Clean Air Act (CAA) requirements and demonstrates that the Vancouver portion of the Pdx/Van AQMA will be able to remain in attainment for 1997 and 2008 ozone NAAQS through 2015. EPA is proposing full approval of the maintenance plan and supporting rules.
