Public Notice:  The Washington State Department of Ecology has prepared an Exceptional Event Demonstration report that shows how high winds overwhelmed agriculture erosion controls and caused particle pollution levels to exceed the 24-hour PM10 National Ambient Air Quality Standard (NAAQS) at Kennewick on August 14, 2015. When EPA approves the demonstration report, this exceedance will be excluded during evaluation of area compliance status.

We invite the public to review and comment on the proposed report through October 25, 2017. The report is available at
