The Gateway Partnership Act aims to allow the Secretary of the Interior to create an agreement with the Gateway Arch Park Foundation. This agreement will enable the Foundation to host private events in certain buildings within the Gateway Arch National Park. The key provisions of this act include the establishment of specific terms for the agreement. These terms will ensure that the events do not harm the park's resources or disrupt public access. The Foundation will be allowed to hold a limited number of events, and the agreement will specify the maximum number of events per week.
