Welcome to the home page for the Indiana Department of Health (IDOH) information on mass gatherings. IC 16-41-22 establishes the minimum standards for Mass Gatherings. The Mass Gathering Act, administered by local officials, requires a license issued by the local Sheriff once the promoter of the event demonstrates compliance with the Act. The Act also serves as a guide to health and safety issues for large events that do not meet the definition of a Mass Gathering. The act prohibits a person from permitting, maintaining, promoting, conducting, advertising, acting as an entrepreneur, undertaking, organizing, managing, or selling or giving tickets to an actual or a reasonably anticipated assembly of at least five thousand (5,000) people that continues or can reasonably be expected to continue for at least eighteen (18) consecutive hours, whether on public or private property unless a license to hold the assembly has first been issued by the appropriate law enforcement official of the unit in which the assembly is to gather.
The act does not apply to a regularly established, permanent place of worship, a stadium, an athletic field, an arena, an auditorium, a coliseum, or other similar permanently established place of assembly for assemblies that do not exceed more than two hundred fifty (250) people the maximum seating capacity of the structure where the assembly is held. It also does not apply to government-sponsored fairs held on regularly established fairgrounds or to assemblies required to be licensed by other statutes or ordinances. It does not apply to local or regional festivals, celebrations, or events that are held on an annual or regular basis and that were observed or celebrated at least two (2) times before January 1, 1973. And to assemblies that are held on land owned or leased by the state or the federal government.

Many frost-proof hydrants and exterior drinking fountains allow for possible back-siphonage of contaminated water into a water distribution system. Therefore, approved non-freeze, non-polluting sanitary exterior drinking fountains and yard hydrants are required to be installed in facilities that are reviewed by this program.
