The Environmental Protection Agency (EPA) is proposing to make a finding of attainment by the attainment date and a clean data determination (CDD) for the Oakridge-Westfir (Oakridge), Oregon fine particulate matter nonattainment area (Oakridge NAA). The finding is based upon quality-assured, quality-controlled, and certified ambient air monitoring data showing the area has monitored attainment of the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) based on 2014-2016 data available in the EPA's Air Quality System (AQS) database. If finalized, this determination will not constitute a redesignation to attainment. The EPA also proposes to approve revisions to Oregon's State Implementation Plan (SIP) consisting of the updated Oakridge-Westfir PM<INF>2.5</INF> Attainment Plan (Oakridge Update) submitted by the Oregon Department of Environmental Quality (ODEQ) on January 20, 2017. The purpose of the Oakridge Update, developed by Lane Regional Air Protection Agency (LRAPA) in coordination with the ODEQ, is to provide an attainment demonstration of the 2006 24-hour PM<INF>2.5</INF> NAAQS and correct deficiencies in the 2012 Oakridge Attainment Plan.
