Our goals for achieving natural quiet in the Grand Canyon
The Grand Canyon Trust will continue to work on natural quiet issues to ensure that...
- The negative impacts to natural quiet from low-level air tours and other aircraft are minimized by the adoption of new regulations that “substantially restore natural quiet” to Grand Canyon National Park, as required by the Grand Canyon Overflights Act.
- The NPS selects a preferred alternative that substantially restores natural quiet to the Grand Canyon.
- The FAA adopts regulations to implement that alternative.
- The NPS continues to monitor aircraft noise over the Grand Canyon.
We’ve already accomplished much.
The Trust has participated with the National Parks and Conservation Association, Sierra Club, and other “quiet canyon” advocates in reviewing and commenting on proposed plans and new regulations to restore “natural quiet” to the Grand Canyon. Our major accomplishments have included:
- Helping pass the 1987 National Parks Overflights Act.
- Initiating a series of legal actions to enforce the law.
- Blocking attempts by legislators funded by the air-tour-industry to amend the 1987 Act and to remove NPS authority to regulate noise from air tours.
