MIAG - AMS

Smoke management decision support for member burners including meteorology and notification with be coordinated through the AMS website for the spring season (3/1/19 - 5/31/19). It is the responsibility of the burner to review and comply with any/all restrictions/regulations issued by county, state, and tribal coordinators/officials prior to ignition. The ultimate responsibility for the effects of conducting a prescribed burn, including any smoke impacts, lies with the Burn Boss. Change the status of burns to "complete" as they are completed.
