Summary of Wallula Particulate Matter (PM-10) Maintenance Plan
The Wallula, Washington, area was designated nonattainment for PM10 and classified as moderate upon enactment of the Clean Air Act Amendments in 1990.
The area was later redesignated as a serious nonattainment area on February 9, 2001 (66 FR 9663 (PDF)(11 pp, 172 K, About PDF)).
On May 2, 2005, EPA approved the Wallula PM10 attainment plan (70 FR 22597 (PDF)(3 pp, 149 K)).
On March 29, 2005, Washington submitted a maintenance plan and request for redesignation to attainment for the Wallula PM10 nonattainment area. EPA approved the maintenance plan on August 26, 2005 (70 FR 50212 (PDF)(3 pp, 150 K)).
The plan relies on a control strategy that focuses on the control of fugitive dust from agricultural sources and a composting operation to assure attainment of the PM10 National Ambient Air Quality Standards (NAAQS).
