A bill 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 in the Mashpee Wampanoag Tribe Reservation and land held in trust for the Wampanoag Tribe of Gay Head (Aquinnah), and for other purposes.

This bill (S 236) amends the Long-Term Leasing Act to allow the Mashpee Wampanoag Tribe and the Wampanoag Tribe of Gay Head (Aquinnah) to lease reservation and trust land for up to 99 years. It directly affects these two federally recognized tribes by expanding their authority to lease tribal land under the existing leasing framework. The key provision modifies the 1955 Act to specifically include their lands in the leasing authority, replacing a reference to the Chehalis Reservation. This change would enable tribes to enter longer-term leases for economic development or other purposes on their designated lands.
