Maine rules specifically ban three types of fireworks — bottle rockets, sky rockets (or finned missiles) and bladed helicopter-type fireworks. In addition to the state rules, 68 Maine cities and towns have adopted their own rules for fireworks use and sale.
In Lewiston, fireworks are allowed on only three days of the year, and even then only in the outskirts of the city — the same area as the city's firearms discharge zone. That zone is outside of a half-circle that runs from the Androscoggin River, south of Merrill Road, follows transmission lines east to Grove Street and to the eastern limit of the city. From there, it follows the Maine Turnpike back to the river. For anywhere inside that circle, fireworks possession and use is banned year-round.
Outside of that zone, fireworks are allowed on three dates — July 4, Dec. 31 and Jan. 1 — no earlier then 10 a.m. and no later then 10 p.m.. They are not allowed on public property — including parks, roads and schools — must not be within 75 feet of any building and cannot be used if the fire chief has declared a fire danger.
Auburn's rules are much more simple: Fireworks are not allowed within the city limits.
Sabattus goes the other way, allowing fireworks on any day that the Maine Forest Service does not declare a Class 4 fire danger or greater.
Mechanic Falls allows fireworks on any Friday or Saturday after sunset and until 10 p.m. They are also allowed from 9:30 a.m. July 4 until 12:30 a.m. the following day and for the same time on July 3 and 5 if those days fall on a weekend. Mechanic Falls also allows fireworks on New Year's Day.
Livermore Falls residents can use fireworks in the village area from 10 a.m. to 10 p.m. any day of the year, and until 12:30 a.m. on July 5 and on New Year's Eve. They're allowed on the Saturday and Sunday immediately before or after those days, as well. They can't be shot off within 50 feet of a house or if the Maine Forest Service declares a Class 4 fire danger or greater.
