Summary of Oakridge PM2.5 Attainment Plan
Background
The Oakridge-Westfir area within Lane County Oregon was designated nonattainment for PM2.5 on November 13, 2009 (74 FR 58688 (pdf)) and later classified as moderate on June 2, 2014 (79 FR 31566 (pdf)).
The Oregon Department of Environmental Quality submitted the Lane Regional Air Protection Agency’s (LRAPA) Oakridge-Westfir PM2.5 attainment plan on December 12, 2012.
Oakridge did not meet the statutory attainment date of 2015 based on its three year design value, although the area met the criteria for extending its attainment date by one year, and the EPA extended its attainment date to December 31, 2016 on July 18, 2016 (81 FR 46612 (pdf)).
On July 28, 2016 (81 FR 49592 (pdf)) the EPA proposed, and on October 21, 2016 (81 FR 72714 (pdf)) the EPA finalized approval of the emissions inventory and the LRAPA rules describing the Oakridge-Westfir PM2.5 nonattainment area and listing of the area as nonattainment. The remaining elements of the plan were disapproved.
Summary
The plan is a partial approval and partial disapproval of the Oakridge-Westfir PM2.5 attainment plan submitted December 12, 2012. This action approves the base year 2008 emissions inventory submitted to meet the CAA section 172(c)(3) requirement for the emissions inventories and the LRAPA rules describing the Oakridge PM2.5 nonattainment area and listing of the area as nonattainment. The remaining elements of the plan were disapproved.
