The permit shall consist of a basic fee of two hundred fifty dollars ($250) for each year of the permit, plus an additional acreage fee of twenty-five dollars ($25.00) for each acre or fraction thereof of the land affected by the operation, not to exceed two thousand five hundred dollars ($2,500) for such acreage fee, but in subsequent years no acreage fee will be charged for any acre on which the acreage fee has already been paid in the preceding years. No permit fee shall be charged for land upon which overburden is deposited if, in the opinion of the commissioner, the deposition of such overburden amounts to reclamation of a previously mined area. The supplemental basic fee for an amendment of a permit shall be fifty dollars ($50.00), and to the extent the amendment entails an increase or decrease in the acreage covered by the permit, the total acreage fee paid for the year shall be correspondingly increased or decreased by the amount per acre or fraction thereof specified hereinabove.
