18 U.S.C. § 4003 — Federal institutions in States without appropriate facilities

If by reason of the refusal or inability of the authorities having control of any jail, workhouse, penal, correctional, or other suitable institution of any State or Territory, or political subdivision thereof, to enter into a contract for the imprisonment, subsistence, care, or proper employment of United States prisoners, or if there are no suitable or sufficient facilities available at reasonable cost, the Attorney General may select a site either within or convenient to the State, Territory, or judicial district concerned and cause to be erected thereon a house of detention, workhouse, jail, prison-industries project, or camp, or other place of confinement, which shall be used for the detention of persons held under authority of any Act of Congress, and of such other persons as in the opinion of the Attorney General are proper subjects for confinement in such institutions.
