ALERT (UPDATE): State Agriculture Commissioner Jai Templeton has issued a burn ban for Clairborne, Cumberland, Hamilton, Jefferson, Loudon, Marion, Monroe, Robertson and Sevier counties. The burn ban is effective immediately and will remain in place until further notice.
The ban applies to all open-air burning including leaf and woody debris and construction burning, campfires, outdoor grills and other fire activity in areas outside of municipalities where local ordinances apply.  Counties not listed under the ban require a safe debris burning permit now through May 15, 2017 from the Tennessee Department of Agriculture (TDA) Division of Forestry (exceptions: Da­vidson, Knox, Madison and Shelby, which never allow debris burning). Permits will only be issued where and when it is determined to be safe to do so.
