This bill, known as the Gateway Partnership Act, authorizes the Secretary of the Interior to enter into an agreement with the Gateway Arch Park Foundation . This agreement would permit the Foundation, the official philanthropic partner of the Park, to host private events within Gateway Arch National Park buildings, including the Arch Visitor Center and the Old Courthouse. The agreement must include specific terms and conditions to protect park resources, such as requiring liability insurance that names the United States as additionally insured and ensuring the federal government is not liable for damages. Events must be consistent with the park's purposes and National Park Service programs, explicitly prohibiting activities that degrade the park or disrupt public access. To cover associated expenses, the Secretary is mandated to charge a fee for wear and tear and may recover all costs, including administrative and personnel expenses. This authorization does not, however, prevent the National Park Service from hosting its own events or issuing permits to other entities.
