Pub. L. 91-173, tit. IV, pt. C, sec. 426

Sec. 426. (a) The Secretary of Labor and the Secretary of Health, Education, and Welfare are authorized to issue such regulations as each deems appropriate to carry out the provisions of this title. Such regulations shall be issued in conformity with section 553 of title 5 of the United States Code, notwithstanding subsection (a) thereof. (b) Within 120 days following the convening of each session of Congress the Secretary of Health, Education, and Welfare shall submit to the Congress an annual report upon the subject matter of part B of this title, and, after January 1, 1973, the Secretary of Labor shall also submit such a report upon the subject matter of part C of this title. (c) Nothing in this title shall relieve any operator of the duty to comply with any State workmen’s compensation law, except insofar as such State law is in conflict with the provisions of this title and the Secretary by regulation, so prescribes. The provisions of any State workmen’s compensation law which provide greater benefits than the benefits payable under this title shall not thereby be construed or held to be in conflict with the provisions of this title.
