30 U.S. Code § 943 - Black lung insurance program
The Secretary is authorized to establish and carry out a black lung insurance program which will enable operators of coal mines to purchase insurance covering their obligations under section 932 of this title.
The Secretary may exercise his or her authority under this section only if, and to the extent that, insurance coverage is not otherwise available, at reasonable cost, to operators of coal mines.
The Secretary may undertake and carry out such studies and investigations, and receive or exchange such information, as may be necessary to formulate a premium schedule which will enable the insurance and reinsurance authorized by this section to be provided on a basis which is (1) in accordance with accepted actuarial principles; and (2) fair and equitable.
There are authorized to be appropriated to the insurance fund, as repayable advances, such sums as may be necessary to meet obligations incurred under subsection (g). All such sums shall remain available without fiscal year limitation. Advances made pursuant to this subsection shall be repaid, with interest, to the general fund of the Treasury when the Secretary determines that moneys are available in the insurance fund for such repayments. Interest on such advances shall be computed in the same manner as provided in subsection (b)(2) of section 934a  of this title.
