The purpose of this legislation, known as the "Making National Parks Safer Act," is to enhance emergency communication systems within the National Park System. Specifically, it aims to upgrade existing emergency communications centers to a more advanced system called Next Generation 9-1-1. This upgrade is intended to improve the efficiency and effectiveness of emergency responses in national parks. Key provisions of the legislation include a requirement for the Secretary of the Interior to conduct an assessment of current emergency communications centers within national parks.
