An Act relative to concurrent jurisdiction on National Park Service properties

This bill updates jurisdiction rules for National Park Service (NPS) properties in Massachusetts. It adds "waters" to the definition of covered areas (previously only "lands") and creates a new clause (m) covering all NPS lands, waters, and buildings acquired, leased, or controlled after the law takes effect. The key mechanism requires the NPS Director to file a notice of acceptance with the governor and state secretary to transfer concurrent jurisdiction to the U.S. government for these properties. This clarifies federal authority over NPS properties without changing existing state-federal relationships for older holdings.
