(b) Interim payments into Alaska Native Fund based on percentage of gross value of produced or removed minerals and of rentals and bonuses; time of payment. With respect to conditional leases and sales of minerals heretofore or hereafter made pursuant to section 6(g) of the Alaska Statehood Act, and with respect to mineral leases of the United States that are or may be subsumed by the State under section 6(h) of the Alaska Statehood Act, until such time as the provisions of subsection (c) of this section become operative the State shall pay into the Alaska Native Fund from the royalties, rentals, and bonuses hereafter received by the State (1) a royalty of 2 per centum upon the gross value (as such gross value is determined for royalty purposes under such leases or sales) of such minerals produced or removed from such lands, and (2) 2 per centum of all rentals and bonuses under such leases or sales, excluding bonuses received by the State at the September 1969 sale of minerals from tentatively approved lands and excluding rentals received pursuant to such sale before December 18, 1971. Such payment shall be made within sixty days from the date the revenues are received by the State.
(c) Patents; royalties: reservation of percentage of gross value of produced or removed minerals and of rentals and bonuses from disposition of minerals. Each patent hereafter issued to the State under the Alaska Statehood Act, including a patent of lands heretofore selected and tentatively approved, shall reserve for the benefit of the Natives, and for payment into the Alaska Native Fund, (1) a royalty of 2 per centum upon the gross value (as such gross value is determined for royalty purposes under any disposition by the State) of the minerals thereafter produced or removed from such lands, and (2) 2 per centum of all revenues thereafter derived by the State from rentals and bonuses from the disposition of such minerals.
(d) Distribution of bonuses, rentals, and royalties from Federal disposition of minerals in public lands; payments into Alaska Native Fund based on percentage of gross value of produced minerals and of rentals and bonuses; Federal and State share calculation on remaining balance. All bonuses, rentals, and royalties received by the United States after December 18, 1971, from the disposition by it of such minerals in public lands in Alaska shall be distributed as provided in the Alaska Statehood Act, except that prior to calculating the shares of the State and the United States as set forth in such Act, (1) a royalty of 2 per centum upon the gross value of such minerals produced (as such gross value is determined for royalty purposes under the sale or lease), and (2) 2 per centum of all rentals and bonuses shall be deducted and paid into the Alaska Native Fund. The respective shares of the State and the United States shall be calculated on the remaining balance.
(e) Federal enforcement; State underpayment: deductions from grants-in-aid or other Federal assistance equal to underpayment and deposit of such amount in Fund. The provisions of this section shall be enforceable by the United States for the benefit of the Natives, and in the event of default by the State in making the payments required, in addition to any other remedies provided by law, there shall be deducted annually by the Secretary of the Treasury from any grant-in-aid or from any other sums payable to the State under any provision of Federal law an amount equal to any such underpayment, which amount shall be deposited in the Fund.
(f) Oil and gas revenues; amount payable equal to Federal or State royalties in cash or kind. Revenues received by the United States or the State as compensation for estimated drainage of oil or gas shall, for the purposes of this section, be regarded as revenues from the disposition of oil and gas. In the event the United States or the State elects to take royalties in kind, there shall be paid into the Fund on account thereof an amount equal to the royalties that would have been paid into the Fund under the provisions of this section had the royalty been taken in cash.
(g) Alaska Native Fund payments; cessation; reimbursement for advance payments. The payments required by this section shall continue only until a sum of $500,000,000 has been paid into the Alaska Native Fund less the total of advance payments paid into the Alaska Native Fund pursuant to section 407 of the Trans-Alaska Pipeline Authorization Act. Thereafter, payments which would otherwise go into the Alaska Native Fund will be made to the United States Treasury as reimbursement for the advance payments authorized by section 407 of the Trans-Alaskan Pipeline Authorization Act. The provisions of this section shall no longer apply, and the reservation required in patents under this section shall be of no further force and effect, after a total sum of $500,000,000 has been paid to the Alaska Native Fund and to the United States Treasury pursuant to this subsection.
(h) Final payment; order of computation. When computing the final payment into the Fund the respective shares of the United States and the State with respect to payments to the Fund required by this section shall be determined pursuant to this subsection and in the following order:
(2) then, from sources identified under subsection (d) hereof.
