Department of Ecology News Release - May 16, 2002

YAKIMA - If you live in Eastern Washington, you know it can be dusty out there. The Washington State Department of Ecology reminds residents there are things they can do when it's windy and the dust clouds start to form.
Eastern Washington dust storms normally occur in sustained winds above 20 miles per hour, but as dry conditions persist, dust clouds may form at lower wind speeds.
Particulate matter in dust storms is very small and can be inhaled deeply into the lungs, where it can damage sensitive tissues. People with respiratory illnesses, the elderly, young children, pregnant women and anyone engaged in strenuous physical activity outdoors are most at risk.
When a dust storm occurs, people can reduce their exposure to particulate matter by:
Fine dust can remain suspended in the air after the wind stops blowing. Air in some low-lying areas can become "stagnant" and particles may settle out of the air slowly. People interested in preparing for dust storms should keep abreast of local weather forecasts. "Real time" air quality data is available by county online at https://fortress.wa.gov/ecy/enviwa/, where available. (Link updated 01/18/08))
Everyone can help reduce airborne dust and smoke by driving slower on unpaved roads, delaying dusty projects around the house and yard, and obeying fire restrictions. In addition, dust control is required for all construction projects. Control measures include clearing no more land than needed, working in phases to minimize the amount of exposed area, using a commercial dust suppressant to replace or reduce the use of water, covering bare ground with gravel, and curtailing activities on windy days.
