(a) Establishment of reserves for reclamation and closing costs.
(1) Allowance of deduction. If a taxpayer elects the application of this section with respect to any mining or solid waste disposal property, the amount of any deduction for qualified reclamation or closing costs for any taxable year to which such election applies shall be equal to the current reclamation or closing costs allocable to--

(2) Opening balance and adjustments to reserve.
(A) Opening balance. The opening balance of any reserve for its first taxable year shall be zero.
(B) Increase for interest. A reserve shall be increased each taxable year by an amount equal to the amount of interest which would have been earned during such taxable year on the opening balance of such reserve for such taxable year if such interest were computed--

(ii) by compounding semiannually.
(C) Reserve to be charged for amounts paid. Any amount paid by the taxpayer during any taxable year for qualified reclamation or closing costs allocable to portions of the reserve property for which the election under paragraph (1) was in effect shall be charged to the appropriate reserve as of the close of the taxable year.

(C) Order of application. This paragraph shall be applied after all adjustments to the reserve have been made for the taxable year.
