(b) Reimbursement

(1) In general

The Secretary of Energy shall, subject to paragraph (2), reimburse at least annually a licensee described in subsection (a) for such portion of the costs described in such subsection as are—

(2) Amount

(A) To individual active site uranium licensees

The amount of reimbursement paid to any licensee under paragraph (1) shall be determined by the Secretary in accordance with regulations issued pursuant to section 2296a-1 of this title and, for uranium mill tailings only, shall not exceed an amount equal to $6.25 multiplied by the dry short tons of byproduct material located on October 24, 1992, at the site of the activities of such licensee described in subsection (a), and generated as an incident of sales to the United States.

(B) To all active site uranium licensees

Payments made under paragraph (1) to active site uranium licensees shall not in the aggregate exceed $350,000,000.

(ii) In the event of excess

If the Secretary determines under clause (i) that there is an excess, the Secretary may allow reimbursement in excess of $6.25 per dry short ton on a prorated basis at such sites where the costs reimbursable under subsection (b)(1) exceed the $6.25 per dry short ton limitation described in paragraph (2) of such subsection.

(3) Byproduct location

Notwithstanding the requirement of paragraph (2)(A) that byproduct material be located at the site on October 24, 1992, byproduct material moved from the site of the Edgemont Mill to a disposal site as the result of the decontamination, decommissioning, reclamation, and other remedial action of such mill shall be eligible for reimbursement to the extent eligible under paragraph (1).
