MIAG - AMS

Smoke management decision support for member burners including meteorology and notification with be coordinated through the AMS website for the fall season (9/1/19 – 11/30/19). It is the responsibility of the burner to comply with any/all restrictions/regulations issued by county, state, and tribal coordinators/officials. The ultimate responsibility for the effects of smoke impacts from conducting a prescribed burn lies with the practitioner. **** Change the status of any existing approved burns to completed and enter burned acres***
