What pollutants are being monitored and used in the AQI?
• Are these pollutants a problem year-round? No, ozone is the main pollutant of concern in the summer. Whereas, particulates are closely tracked in the winter. • Why is the AQI used? The AQI used to establish burn bans. In the summer, if the AQI is 60 or higher and stagnant air conditions are expected to continue for at least 24 hours, then all outside open burning activities are banned. In the winter, if the AQI is 74 or higher and stagnant air conditions are expected to continue for at least 24 hours, a wood burn ban is initiated. • Is the AQI updated on weekends? It depends. If the air quality is expected to remain poor or get worse over the weekend, DEQ will update the AQI information and post it on the AQI hotline and the DEQ web site. If you check the AQI over the weekend and Friday’s information is still posted, it is OK to burn as long as the AQI is below 60 (summer) or 74 (winter). Burn bans • How will I know if there is an open burning or wood burning ban?
