Amends TCA Title 5 and Title 68, Chapter 2, Part 6.

This bill provides that, if a county or city experiences a health emergency, including, without limitation, a state-wide declaration of the existence of a health epidemic or pandemic, a county-wide or city-wide epidemic, or the imminent threat of an epidemic or pandemic, resulting in the need for health policies that affect the entire county or city, then the county mayor has the exclusive authority in the unincorporated areas of the county, and the highest-ranking elected official of the city has the exclusive authority in the official's jurisdiction, to establish and implement such policies under advisement from the county health director or county health officer, or both, as necessary. In a county with a county board of health or a health committee, or both, such bodies will become advisory to the county mayor and the highest-ranking officials of each city in the county. This bill will apply to Shelby, Davidson, Knox, Hamilton, Sullivan, and Madison counties.
