H. R. 9410 lets the Secretary of the Interior make a deal with the Gateway Arch Park Foundation to have special parties in park buildings, as long as they take care of the park and don't block people from visiting. They also have to make sure there are rules for keeping the park safe and fixing stuff that might get worn out.
