Washington Air Quality Advisory

Air Quality Monitoring

An Ozone monitor has been installed in Kennewick; there will now be two monitors shown on Ecology's Monitoring web page. In Kennewick, the eastern "dot" shows PM10 and PM2.5; the western Ozone.

These pollutants are independenly monitored and reported through the Air Quality Index; so the monitors may show different colors.

They can be seen together at AIr Now.; along with air quality information for the entire US.


Benton County, in south central Washington, includes the cities of Kennewick, Richland, West Richland, Benton City and Prosser. The Columbia River makes up the county boundaries to the north, east and south. Benton County includes confluence of the Snake, Yakima and Columbia rivers, along with the Horse Heaven Hills and the lower Yakima Valley.

Nestled in the heart of Washington’s wine country, Benton County is home to five of Washington State’s eight American Viticulture Areas, the region produces 99 percent of the state’s wine and some of the finest wines in the world. An annual $3 billion industry, Washington State is the second largest wine producer in the nation.

The area is also known for its advances in science and technology, which have carried over to excellent educational opportunities in each of our local school districts, as well as opportunities in higher education.

The climate is semi-arid and the shrub-steppe ecology, along with the rivers, parks, and ridgelines, make Benton County a unique environment.

Benton Clean Air Agency works with citizens and industries to maintain and preserve the air quality and its contribution to public health and safety, and the enjoyment by all of our natural resources.

Windblown Dust

State of Washington Notice of Opportunity to comment on proposed Exceptional Event Demonstration

Three unusual thunderstorms created strong winds and dust in Eastern Washington in 2013. The storms overwhelmed agriculture erosion controls and caused air pollution from dust to exceed federal standards. Ecology’s report shows that the dust storms were “Exceptional Events” and is asking EPA to leave out the values from these events when determining compliance with air quality standards.  Comment period September 3 to October 5, 2015.
