43 U.S.C. § 1733 — Enforcement authority

(a) Regulations for implementation of management, use, and protection requirements; violations; criminal penalties.— The Secretary must issue regulations needed to carry out this Act’s provisions about managing, using, and protecting the public lands, including property on those lands. A person who knowingly and willfully violates such a regulation that was lawfully issued under this Act may be fined up to $1,000, imprisoned for up to 12 months, or both. A person charged with violating such a regulation may be tried and sentenced by a United States magistrate judge designated for that purpose by the court that appointed the judge. The trial and sentence must follow section 3401 of title 18, including its conditions and limits.
(b) Civil actions by Attorney General for violations of regulations; nature of relief; jurisdiction.— At the Secretary’s request, the Attorney General may bring a civil action in any United States district court for an injunction or another appropriate order. The action may prevent a person from using public lands in violation of the Secretary’s regulations under this Act.
(c) Contracts for enforcement of Federal laws and regulations by local law enforcement officials; procedure applicable; contract requirements and implementation.— (1) If the Secretary decides that help is needed to enforce Federal laws and regulations about public lands or their resources, the Secretary must offer a contract to appropriate local officials who have law-enforcement authority in their own jurisdictions. The goal is to rely as much as feasible on local law-enforcement officials to enforce those laws and regulations. The Secretary must negotiate on reasonable terms with officials who may enter into such contracts. While carrying out their duties under the contracts, the officials and their agents may carry firearms; execute and serve warrants or other process issued by a court or an officer with proper jurisdiction; arrest without a warrant or process a person for a misdemeanor when the official has reasonable grounds to believe the misdemeanor is being committed in the official’s presence or view; arrest without a warrant or process a person for a felony when the official has reasonable grounds to believe the person committed or is committing the felony; search without a warrant or process any person, place, or vehicle as allowed by Federal law or a rule of law; and seize without a warrant or process any evidence as allowed by Federal law. The Secretary must provide the law-enforcement training the Secretary considers necessary to carry out the contracted responsibilities. While using the powers and authority provided by a contract under this section, the law-enforcement officials and their agents have all the immunities of Federal law-enforcement officials. (2) The Secretary may authorize Federal personnel or appropriate local officials to carry out the Secretary’s law-enforcement responsibilities concerning public lands and their resources. The designated personnel must receive the training and have the responsibilities and authority provided in paragraph (1) of this subsection.
(d) Cooperation with regulatory and law enforcement officials of any State or political subdivision in enforcement of laws or ordinances.— In administering and regulating the use and occupancy of public lands, the Secretary may cooperate with the regulatory and law-enforcement officials of any State or political subdivision of a State to enforce that State’s or subdivision’s laws or ordinances. This cooperation may include reimbursing a State or its political subdivision for expenses it incurs on activities that assist in administering and regulating the use and occupancy of public lands.
(e) Uniformed desert ranger force in California Desert Conservation Area; establishment; enforcement of Federal laws and regulations.— Nothing in this section prevents the Secretary from promptly establishing a uniformed desert ranger force in the California Desert Conservation Area established under section 1781 of this title. The force would enforce Federal laws and regulations concerning the public lands and resources the Secretary manages in that area. Its officers and members have the same responsibilities and authority provided in paragraph (1) of subsection (c) of this section.
(f) Applicability of other Federal enforcement provisions.— Nothing in this Act reduces or limits the enforcement authority that any other statute gives the Secretary.
(g) Unlawful activities.— Using, occupying, or developing any portion of the public lands contrary to a regulation of the Secretary or another responsible authority, or contrary to an order issued under such a regulation, is unlawful and prohibited.
