Air Quality Index Information

The above map reflects the most recent Air Quality Index (AQI) for today at each of the air monitoring stations. Station data is refreshed at the top of every hour, but may not be shown immediately due to data transfer and verification limitations. The AQI represents a weighted rolling average concentration over 24 hours for PM10 and PM2.5; and 8 hours for Ozone.

On "Marginal" days, it is a No Burn day except for the following types of burns:

• Permitted Backyard Burns (during December-April)
• Ag Burns that will burn less than 5 tons of vegetation
• Prescribed Burns that will burn less than 5 tons of vegetation (Please see note below, the Air District may allow larger burns if all permit requirements are met and site specific conditions are favorable to minimize smoke impacts.)

For prescribed burns that will burn more than 5 tons of vegetation and the 24 hour forecast or 48 hour burn day outlook is Marginal, please contact the Air District at 831-647-9411 at least 24-hours in advance, Monday-Friday for consideration of site specific conditions.

All Burns must receive a separate "daily authorization" from the permitting agency (fire agency or Air District) prior to conducting the burn.

All other burns, contact the Air District at 831-647-9411 prior to burning.

Note: The Air District may declare a "Marginal" day as a "No Burn" day if weather conditions are limited in providing dispersion of pollutants.
