44 U.S.C. § 1507

A document required by section 1505(a) of this title to be published in the Federal Register is not valid as against a person who has not had actual knowledge of it until the document has been filed with the Office of the Federal Register and a copy made available for public inspection as provided by section 1503 of this title. Unless otherwise specifically provided by statute, filing of a document, required or authorized to be published by section 1505 of this title, except in cases where notice by publication is insufficient in law, is sufficient to give notice of the contents of the document to a person subject to or affected by it. The publication in the Federal Register of a document creates a rebuttable presumption—The contents of the Federal Register shall be judicially noticed and without prejudice to any other mode of citation, may be cited by volume and page number.
