Missouri Festivals — RSMo ch. 316, §§ 316.150–316.185 (medical plan requirement at § 316.160(8))[1]
Summary
Missouri's Festivals act (L. 1975 S.B. 323) is a county-licensing statute for ticketed music events. A "festival" is any music, dance or rock festival or similar musical activity expected to attract 5,000 or more persons, lasting 12 or more hours, open to the public for a charge. A county licence is required before operating, conducting, advertising or selling tickets, with written application to the county clerk at least 60 days before the event and a non-refundable fee capped at $100. There are no staffing ratios and no physician or EMS mandate in the statute: § 316.160(8) requires that the application include plans for "security and fire protection, water supply and facilities, food supply and facilities, sanitation facilities, medical facilities and services," and adequacy is judged by the county, which may attach reasonable conditions. The act excludes charter counties of 900,000 or more population, so large-metro events are governed by county or municipal ordinance instead.
So what
Missouri compels a medical facilities and services plan but supplies no content standard, so the county governing body's "reasonable conditions" power at the public hearing is where an event's medical footprint is actually decided — bring a defensible plan to that hearing rather than expecting a table to follow. The act is narrow: it reaches only ticketed musical events of 5,000-plus lasting 12-plus hours, so sporting, religious and free events are outside it, as are events in charter counties above 900,000 population. Statewide, ambulance services and EMS personnel remain licensed under RSMo ch. 190 regardless.
