High Wind Dust Mitigation Plan for Wallula Area

Maintenance State Implementation Plan

November 5, 2018 - December 12, 2018

Ecology has a plan to reduce dust during high winds in the Wallula area.  The plan:
  • Identifies existing sources and controls of dust.
  • Includes new plans to encourage farmers to use additional measures to reduce soil erosion.


We monitor the air for dust in some areas of Washington.  Monitors track air quality to measure whether areas meet national ambient air quality standards (NAAQS), which are set by EPA.

Between 2013 and 2015, air pollution from coarse particles (PM10) in dust caused the Kennewick monitor to go above the national air quality standard three times.  This monitor stands in for the Wallula PM10 maintenance area, an area that previously didn't meet the standard.  The exceptional events rule requires us to develop a new plan to reduce coarse particle pollution for areas near and around Kennewick.
