To amend the Act of August 9, 1955 (commonly known as the "Long-Term Leasing Act"), to authorize leases of up to 99 years for land held in trust for the Mashpee Wampanoag Tribe and the Wampanoag Tribe of Gay Head (Aquinnah), and for other purposes.

This bill would amend the Long-Term Leasing Act (the 1955 act) to explicitly authorize long-term leases—up to 99 years—for land held in trust for the Mashpee Wampanoag Tribe and the Wampanoag Tribe of Gay Head (Aquinnah). Specifically, it adds these two reservations to the list of reservations where such long-term leases are permitted, bringing them into alignment with other tribes already covered by the law. The practical effect is to give these two tribes the same leasing flexibility that other federally recognized tribes have under the act, facilitating financing, development, and use of trust lands over extended terms.
