Maine Mass Gatherings — 22 M.R.S. ch. 265 (§§ 1601–1607) and 10-144 CMR ch. 214[1]
Summary
Maine's 1971 post-Woodstock statute is alive and state-administered. A mass outdoor gathering means "any gathering held outdoors with the intent to attract the continued attendance of 2,000 or more persons for 12 or more hours"; a permit from the Commissioner of Health and Human Services is required before sponsoring, promoting or conducting one. Before issuing, the commissioner must consider the availability of "[a]dequate medical supplies and care," among other items. The implementing rule, 10-144 CMR ch. 214, is a hybrid: the application must include a detailed description of medical facilities and services including the names, positions and qualifications of medical personnel with a statement whether they will be on site or on call, on-site facilities, supplies and first aid vehicles, communications, and whether area hospitals have been advised. The rule's standards are guideline-grade: emergency medical services "should be provided under the supervision of a licensed physician," a first aid building or tent "should be available," and emergency first aid vehicles "should be available on site during the complete time of mass gathering."
So what
Maine is the archetype of the mandatory-plan, advisory-standard model: the permit application forces a written medical plan naming credentialed personnel and their on-site versus on-call status, but the staffing benchmarks are "should" language, so the plan you file becomes the standard against which you will be judged. Expect physician-supervised EMS, a first-aid building or tent, and on-site emergency vehicles for the full event duration as the review baseline, negotiated with Maine CDC reviewers and the host municipality. Two traps: agricultural fairs and harness-racing licensees are statutorily exempt, and towns frequently have their own mass-gathering ordinances with triggers lower than 2,000 for 12 hours, which the state permit does not preempt.
