The main purpose of this legislation, known as the Wintergreen Emergency Egress Act, is to require the Secretary of the Interior to grant permission for a specific emergency exit route on land managed by the National Park Service in Virginia. This route is intended to improve safety and access during emergencies, particularly in areas prone to wildfires. Key provisions of the Act include a mandate for the Secretary of the Interior to issue a right-of-way for the emergency exit, which is outlined in a specific map.
