EUGENE, Ore.--With the cold weather and no rain, air quality in our area is becoming a concern.
Pollution is getting trapped in the valley, and it could affect you this week.
We spoke to the Air Protection Agency. They say it's typical this time of year. They say when it gets cold without rain, the air becomes still and doesn't move around.
Warmer air then rises and creates a cap over the valley, where polluted air gets stuck.
The agency said there are warning signs people should look out for. "On these really cold, still days.. You'll notice that it's pretty foggy outside. You'll smell a strong scent of wood smoke. It may even feel like campfire smoke that you're walking through. And a lot of that is because there's not a lot of wind or rain.. Or any other precipitation to clear the air," Jo Niehaus with public affairs said.
If the air quality gets bad enough, you may have to limit wood burning activities.
Conditions change daily, so you can check the LRAPA website to make sure you're not violating any rules.
If the air quality rating is red, you can't produce any smoke out of a chimney.
You can fill out an exemption if you need to burn wood for heat.
