The "9/11 Memorial and Museum Act" proposes a one-time federal grant to support the National September 11 Memorial & Museum at the World Trade Center. This grant, ranging from $5,000,000 to $10,000,000 , would be awarded by the Secretary of Homeland Security to an eligible 501(c)(3) organization responsible for the museum's operation. Its primary purpose is to fund the operation, security, and maintenance of the memorial and museum, ensuring its continued ability to commemorate the events and honor the victims of the 2001 terrorist attacks. To qualify, the entity must provide free admission for active and retired military, 9/11 first responders, and victims' families, alongside dedicated free public admission hours weekly. It must also allow annual Federal audits of its financial statements, which will be publicly accessible. The Secretary will determine the grant amount based on factors like security needs, visitor benefit, preservation efforts, educational initiatives, and increasing access for economically disadvantaged visitors. The recipient is required to submit annual reports to Congress detailing the obligation and expenditure of funds. This grant is subject to the availability of appropriations, with no additional funds authorized by the Act itself.
