30 CFR § 870.12 - Reclamation fee.
(1) The initial bona fide sale, transfer of ownership, or use shall be determined by the first transaction or use of the coal by the operator immediately after it is severed, or removed from a reclaimed coal refuse deposit.
(i) Impurities that have not been removed prior to the time of initial bona fide sale, transfer of ownership, or use by the operator, excluding excess moisture for which a reduction has been taken pursuant to § 870.18, shall not be deducted from the gross weight.
(iii) Insufficient records shall subject the operator to fees based on raw tonnage data.
(c) If the operator combines surface mined coal, including reclaimed coal, with underground mined coal before the coal is weighed for fee purposes, the higher reclamation fee shall apply, unless the operator can substantiate the amount of coal produced by surface mining by acceptable engineering calculations or other reports which the Director may require.
