RENO, Nev. (AP) - With the return of colder weather, Washoe County is reinstating its green, yellow, red air quality alert program to advise residents when it's OK to burn wood in their fireplaces and wood stoves.
Wintertime wood burning accounts for nearly 50 percent of fine particulate matter and is a big contributor to cold weather air pollution.
The green, yellow, red alert system will be in effect from November through February.
A green code means the air quality is in the good or low moderate range. Burning of wood, pellets, fire logs and coal is permissible.
When the code is yellow, residents are asked to voluntarily stop burning because of deteriorating air quality.
Red means air quality is unhealthful for people with health problems and all burning is banned.
