## Abstract

On December 12, 2012, the Oregon Department of Environmental Quality (ODEQ) submitted, on behalf of the Governor of Oregon, a State Implementation Plan (SIP) submission to address violations of the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter of less than or equal to a nominal 2.5 micrometers (PM<INF>2.5</INF>) for the Oakridge PM<INF>2.5</INF> nonattainment area (2012 SIP submission). The Lane Regional Air Protection Agency (LRAPA), in coordination with the ODEQ, developed the 2012 SIP submission for purposes of attaining the 2006 24-hour PM<INF>2.5</INF> NAAQS. On February 22, 2016, the ODEQ withdrew certain provisions of the 2012 SIP submission (2016 SIP withdrawal). The Environmental Protection Agency (EPA) has evaluated whether the remaining portions of the 2012 SIP submission meet the applicable Clean Air Act (CAA) requirements. Based on this evaluation, the EPA is finalizing partial approval and partial disapproval of the remaining portions of the 2012 SIP submission.
