# §934. “Fund” defined; liability of operators to United States for repayments to fund; procedures applicable; rate of interest

- (a) For purposes of this section, the term “fund” has the meaning set forth in [section 902(h) of this title](/usc/30/902.md?p=h).
- (b)
  - (1) If—
    - (A) an amount is paid out of the [fund](#a) to an individual entitled to benefits under [section 932 of this title](/usc/30/932.md), and
    - (B) the [Secretary](/usc/30/802.md?p=a) determines, under the provisions of sections [932](/usc/30/932.md) and [933](/usc/30/933.md) of this title, that an [operator](/usc/30/802.md?p=d) was required to secure the payment of all or a portion of such benefits,

    then the [operator](/usc/30/802.md?p=d) is liable to the United States for repayment to the [fund](#a) of the amount of such benefits the payment of which is properly attributed to him plus interest thereon. No [operator](/usc/30/802.md?p=d) or representative of [operators](/usc/30/802.md?p=d) may bring any proceeding, or intervene in any proceeding, held for the purpose of determining claims for benefits to be paid by the [fund](#a), except that nothing in this section shall affect the rights, duties, or liabilities of any [operator](/usc/30/802.md?p=d) in proceedings under [section 932](/usc/30/932.md) or [section 933 of this title](/usc/30/933.md). In a case where no [operator](/usc/30/802.md?p=d) responsibility is assigned pursuant to sections [932](/usc/30/932.md) and [933](/usc/30/933.md) of this title, a determination by the [Secretary](/usc/30/802.md?p=a) that the [fund](#a) is liable for the payment of benefits shall be final.

  - (2) If any [operator](/usc/30/802.md?p=d) liable to the [fund](#a) under [paragraph (1)](#b-1) refuses to pay, after demand, the amount of such liability (including interest), then there shall be a lien in favor of the United States for such amount upon all property and rights to property, whether real or personal, belonging to such [operator](/usc/30/802.md?p=d). The lien arises on the date on which such liability is finally determined, and continues until it is satisfied or becomes unenforceable by reason of lapse of time.
  - (3)
    - (A) Except as otherwise provided under this subsection, the priority of the lien shall be determined in the same manner as under [section 6323 of title 26](/usc/26/6323.md). That section shall be applied for such purposes—
      - (i) by substituting “lien imposed by section 424(b)(2) of the Federal Mine Safety and Health Act of 1977” for “lien imposed by section 6321”; “[operator](/usc/30/802.md?p=d) liability lien” for “tax lien”; “[operator](/usc/30/802.md?p=d)” for “taxpayer”; “lien arising under section 424(b)(2) of the Federal Mine Safety and Health Act of 1977” for “assessment of the tax”; “payment of the liability is made to the Black Lung Disability Trust [Fund](#a)” for “satisfaction of a levy pursuant to section 6332(b)”; and “satisfaction of [operator](/usc/30/802.md?p=d) liability” for “collection of any tax under this title” each place such terms appear; and
      - (ii) by treating all references to the “[Secretary](/usc/30/802.md?p=a)” as references to the [Secretary](/usc/30/802.md?p=a) of Labor.
    - (B) In the case of a bankruptcy or insolvency proceeding, the lien imposed under [paragraph (2)](#b-2) shall be treated in the same manner as a lien for taxes due and owing to the United States for purposes of the Bankruptcy Act or [section 3713(a) of title 31](/usc/31/3713.md?p=a).
    - (C) For purposes of applying [section 6323(a) of title 26](/usc/26/6323.md?p=a) to determine the priority between the lien imposed under [paragraph (2)](#b-2) and the Federal tax lien, each lien shall be treated as a judgment lien arising as of the time notice of such lien is filed.
    - (D) For purposes of this subsection, notice of the lien imposed under [paragraph (2)](#b-2) shall be filed in the same manner as under subsections (f) and (g) of [section 6323 of title 26](/usc/26/6323.md).
  - (4)
    - (A) In any case where there has been a refusal or neglect to pay the liability imposed under [paragraph (2)](#b-2), the [Secretary](/usc/30/802.md?p=a) may bring a civil action in a district court of the United States to enforce the lien of the United States under this section with respect to such liability or to subject any property, of whatever nature, of the [operator](/usc/30/802.md?p=d), or in which he has any right, title, or interest, to the payment of such liability.
    - (B) The liability imposed by [paragraph (1)](#b-1) may be collected at a proceeding in court if the proceeding is commenced within 6 years after the date on which the liability was finally determined, or before the expiration of any period for collection agreed upon in writing by the [operator](/usc/30/802.md?p=d) and the United States before the expiration of such 6-year period. The running of the period of limitation provided under this subparagraph shall be suspended for any period during which the assets of the [operator](/usc/30/802.md?p=d) are in the custody or control of any court of the United States, or of any [State](/usc/30/802.md?p=c), or the District of Columbia, and for 6 months thereafter, and for any period during which the [operator](/usc/30/802.md?p=d) is outside the United States if such period of absence is for a continuous period of at least 6 months.
  - (5) The rate of interest under this subsection—
    - (A) for any period during calendar year 1982, shall be 15 percent, and
    - (B) for any period after calendar year 1982, shall be the rate established by [section 6621 of title 26](/usc/26/6621.md) which is in effect for such period.
