Chaco Cultural Heritage Area Protection Act of 2025

This bill withdraws federal lands surrounding Chaco Culture National Historical Park (a UNESCO World Heritage Site) from oil and gas leasing and development. It automatically terminates non-producing oil and gas leases on these lands and prevents new mineral leasing within the designated area, protecting cultural resources and the park’s visitor experience. The withdrawal specifically applies to federal land within the mapped "Chaco Cultural Heritage Withdrawal Area" but does not affect tribal mineral rights on trust land. It aims to safeguard sacred sites, prehistoric roads, and the park’s dark sky status from potential impacts of energy development.
