An Act relative to concurrent jurisdiction on National Park Service properties

This bill updates Massachusetts state law to include waters and buildings acquired by the National Park Service under its concurrent jurisdiction. It specifically extends this authority to properties obtained on or after the effective date of the act, ensuring federal control over these areas once the National Park Service director notifies the governor and state secretary. The change clarifies that the United States retains jurisdiction over these lands, waters, and structures, preventing state-level conflicts with federal management.
