Officials in Maine’s Acadia National Park are working to prohibit aircraft from flying within the park’s boundaries as a way to keep the landscape quiet, according to the Associated Press.

Acadia Park Planner John Kelly says the park is working with the Federal Aviation Administration (FAA) to establish buffer zones that would extend a half mile from the park’s boundaries and 5,000 feet in the air.

Any rules would not affect aircraft using the Hancock County-Bar Harbor Airport in Trenton, Maine.

He told the Bangor Daily News it’s seen as a way to manage air tours of the park.

Kelly says noise from aircraft is an issue in national parks across the country. In 2000 Congress passed a law requiring the FAA to work with the National Park Service to manage air tours.
