Prohibited activities by United States citizens
30 U.S.C. § 1411
in effect(a) Prohibited activities and exceptions(1) No United States citizen may engage in any exploration or commercial recovery unless authorized to do so under—(A) a license or a permit issued under this subchapter; (B) a license, permit, or equivalent authorization issued by a reciprocating state; or (C) an international agreement which is in force with respect to the United States. (2) The prohibitions of this subsection shall not apply to any of the following activities:(A) Scientific research, including that concerning hard mineral resources. (B) Mapping, or the taking of any geophysical, geochemical, oceanographic, or atmospheric measurements or random bottom samplings of the deep seabed, if such taking does not significantly alter the surface or subsurface of the deep seabed or significantly affect the environment. (C) The design, construction, or testing of equipment and facilities which will or may be used for exploration or commercial recovery, if such design, construction, or testing is conducted on shore, or does not involve the recovery of any but incidental hard mineral resources. (D) The furnishing of machinery, products, supplies, services, or materials for any exploration or commercial recovery conducted under a license or permit issued under this subchapter, a license or permit or equivalent authorization issued by a reciprocating state, or under an international agreement. (E) Activities, other than exploration or commercial recovery activities, of the Federal Government.
(b) Existing exploration(1) Subsection (a)(1)(A) shall not be deemed to prohibit any United States citizen who is engaged in exploration before June 28, 1980, from continuing to engage in such exploration—(A) if such citizen applies for a license under section 1413(a) of this title with respect to such exploration within such reasonable period of time, after the date on which initial regulations to implement section 1413(a) of this title are issued, as the Administrator shall prescribe; and (B) until such license is issued to such citizen or a final administrative or judicial determination is made affirming the denial of certification of the application for, or issuance of, such license. (2) Notwithstanding paragraph (1), if the President by Executive order determines that immediate suspension of exploration activities is necessary for the reasons set forth in section 1416(a)(2)(B) of this title or the Administrator determines that immediate suspension of activities is necessary to prevent a significant adverse effect on the environment or to preserve the safety of life and property at sea, the Administrator is authorized, notwithstanding any other requirement of this chapter, to issue an emergency order requiring any United States citizen who is engaged in exploration before June 28, 1980, to immediately suspend exploration activities. The issuance of such emergency order is subject to judicial review as provided in chapter 7 of title 5. (3) The timely filing of any application for a license under paragraph (1)(A) shall entitle the applicant to priority of right for the issuance of such license under section 1413(b) of this title. In any case in which more than one application referred to in paragraph (1) is filed based on exploration plans required by section 1413(a)(2) of this title which refer to all or part of the same deep seabed area, the Administrator shall, in taking action on such applications, apply principles of equity which take into consideration, among other things, the date on which the applicants or predecessors in interest, or component organizations thereof, commenced exploration activities and the continuity and extent of such exploration and amount of funds expended with respect to such exploration.
(c) InterferenceNo United States citizen may interfere or participate in interference with any activity conducted by any licensee or permittee which is authorized to be undertaken under a license or permit issued by the United States to the licensee or permittee under this chapter or with any activity conducted by the holder of, and authorized to be undertaken under, a license or permit or equivalent authorization issued by a reciprocating state for the exploration or commercial recovery of hard mineral resources. United States citizens shall exercise their rights on the high seas with reasonable regard for the interests of other states in their exercise of the freedoms of the high seas.
