The mandatory standards relating to mines, issued by the Secretary of the Interior under the Federal Metal and Nonmetallic Mine Safety Act [30 U.S.C. 721 et seq.] and standards and regulations under the Federal Coal Mine Health and Safety Act of 1969 [30 U.S.C. 801 et seq.] which are in effect on November 9, 1977, shall remain in effect as mandatory health or safety standards applicable to metal and nonmetallic mines and to coal mines respectively under the Federal Mine Safety and Health Act of 1977 [30 U.S.C. 801 et seq.] until such time as the Secretary of Labor shall issue new or revised mandatory health or safety standards applicable to metal and nonmetallic mines and new or revised mandatory health or safety standards applicable to coal mines.

Within 60 days after November 9, 1977, the Secretary of Labor in consultation with the Secretary of the Interior shall establish an advisory committee under section 102 of the Federal Mine Safety and Health Act of 1977 [30 U.S.C. 812] which shall, within 180 days after the date of the establishment of such advisory committee, review the advisory health and safety standards issued by the Secretary of the Interior under the Federal Metal and Nonmetallic Mine Safety Act and recommend to the Secretary of Labor which of those standards (or any modifications of such standards which do not substantially diminish the health and safety of miners) should be promulgated as mandatory health or safety standards. The Secretary of Labor shall publish, within 60 days after any recommendations of the advisory committee under this paragraph, each of the standards so recommended for adoption with or without modifications as a proposed mandatory health or safety standard under this section by publication of such standard in the Federal Register, and afford interested persons a period of 25 days after publication to submit written data or comment. Within 30 days after the close of the comment period specified in the preceding sentence, the Secretary of Labor shall promulgate by publication in the Federal Register mandatory health or safety standards based upon the advisory committee recommendation with or without modification, and the data and comments received thereon, unless the Secretary of Labor determines that such standards will not promote the health and safety of miners and publishes an explanation of that determination in the Federal Register.

All unexpended balances of appropriations, personnel, property, records, obligations, and commitments which are used primarily with respect to any functions transferred under the provisions of subsection (a) to the Secretary of Labor shall be transferred to the Department of Labor or the Commission, as appropriate. The transfer of personnel pursuant to this paragraph shall be without reduction in classification or compensation for one year after such transfer, except that the Secretary of Labor shall have full authority to assign personnel during such one-year period in order to efficiently carry out functions transferred to him under this Act.

All orders, decisions, determinations, rules, regulations, permits, contracts, certificates, licenses, and privileges (A) which have been issued, made, granted, or allowed to become effective in the exercise of functions which are transferred under this section by any department or agency, any functions of which are transferred by this section, and (B) which are in effect at the time this section takes effect, shall continue in effect according to their terms until modified, terminated, superseded, set aside, revoked, or repealed by the Secretary of Labor, the Federal Mine Safety and Health Review Commission or other authorized officials, by any court of competent jurisdiction, or by operation of law.

The provisions of this section shall not affect any proceedings pending at the time this section takes effect before any department, agency, or component thereof, functions of which are transferred by this section, except that such proceedings, to the extent that they relate to functions so transferred, shall be continued before the Secretary of Labor or the Federal Mine Safety and Health Review Commission. Orders shall be issued in such proceedings, appeals shall be taken therefrom, and payments shall be made pursuant to such orders, as if this section had not been enacted; and orders issued in any such proceedings shall continue in effect until modified, terminated, superseded, revoked, or repealed by the Secretary of Labor, the Federal Mine Safety and Health Review Commission, by a court of competent jurisdiction, or by operation of law. Nothing in this subsection shall be deemed to prohibit the discontinuance or modification of any proceeding under the same terms and conditions and to the same extent that such proceeding could have been discontinued if this section had not been enacted.

The provisions of this section shall not affect suits commenced prior to the date this section takes effect and in all such suits proceedings shall be had, appeals taken, and judgments rendered, in the same manner and effect as if this section had not been enacted; except that if before the date on which this section takes effect, any department or agency (or officer thereof in his official capacity) is a party to a suit involving functions transferred to the Secretary, then such suit shall be continued by the Secretary of Labor. No cause of action, and no suit, action, or other proceeding, by or against any department or agency (or officer thereof in his official capacity) functions of which are transferred by this section, shall abate by reason of the enactment of this section. Causes of actions, suits, actions, or other proceedings may be asserted by or against the United States or the Secretary as may be appropriate and, in any litigation pending when this section takes effect, the court may at any time, on its own motion or that of any party, enter an order which will give effect to the provisions of this paragraph.
