Marine Access and State Transparency or the MAST Act
Amends the Antiquities Act of 1906 to bar the President from declaring any area of the exclusive economic zone to be a national monument unless:
such a declaration is specifically authorized by an Act of Congress;
the President has submitted a proposal to make the declaration to the governor of each state or territory located within 100 nautical miles of that area;
each governor submits to the President a notice that the legislature of that state or territory has approved the proposal; and
the declaration is substantially the same as the proposal.
Prohibits the Department of the Interior or the Department of Commerce, with respect to any area of the exclusive economic zone that is designated as a national monument, from implementing any restrictions on the public use of such a national monument until the expiration of an appropriate review period providing for public input and congressional approval.
