9/1/15: Air Quality Report for NE Oregon and surrounding areas

Air Quality Report, Tuesday  September 1, 2015

NE Oregon, SE Washington and W Central Idaho

Prepared by:  Greg Johnson, Air Resource Advisor, Wallowa-Whitman National Forest, Baker City OR

Except for some valleys just east of the Teepee Springs and Grizzly Bear fires nearly all areas in the region have excellent air quality.  This will continue for the coming 3-5 days as cooler air, southwest to west winds, and good dispersion will move in on Wednesday and Thursday.  Today will still be quite warm and there could be some fire growth issues—south to southwest winds today could be rather strong in some areas.  After today, though, the weather will not favor fire growth so much, and resultant smoke production should also be less.  Rainfall tomorrow through Saturday will generally be light, but the fire areas could receive some helpful light amounts.  Temperatures will go below normal, especially Thursday through Saturday.  Troy is the only location that has really poor air quality, and they will probably continue to suffer with smoke a few more days.  Riggins could have some smoke from Teepee Springs, but most of the time winds will keep smoke up the Salmon River to the east.

AQI Index Actions to Protect Yourself Good Air quality is considered satisfactory, and air pollution poses little or no risk. Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms. Unhealthy for Sensitive Groups - USG Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air Unhealthy            Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects. Very Unhealthy   This would trigger a health alert signifying that everyone may experience more serious health effects. Hazardous This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.

1 Since wildfires often occur in remote areas, air monitoring equipment may not be available. The following table provides a quick method to assess air quality in your area. For more detailed information you can go to the following site: http://www.deq.state.or.us/aq/burning/wildfires/visibility.htm
Using the 5-3-1 Visibility Index
Distance you can see*	Your are:							You have:
	·  An adult ·  A teenager ·  An older child			·  Age 65 and over ·  Pregnant ·  A young child		OR		·  Asthma ·  Respiratory illness ·  Lung or heart disease
5 miles	check visibility			minimize outdoor activity
3 miles	minimize outdoor activity			stay inside
1 mile	stay inside			stay inside
No matter how far you can see, if you feel like you are having health effects from smoke exposure, take extra care to stay inside or get to an area with better air quality.  You should also see your doctor or other health professional as needed.
