Iowa Admin. Code r. 27-40.51
40.51(1) Add to 30 CFR 800.40(c) a paragraph (4) that shall read as follows:
(4) The maximum liability under performance bonds applicable to a permit which may be released at any time prior to the release of all acreage from the permit area shall be calculated by multiplying the ratio between the acreage on which a reclamation phase has been completed and the total acreage in the permit area, times the total liability under performance bonds applicable to a permit, times 0.6 if reclamation phase I has been completed, or 0.25 if reclamation phase II has been completed.
Acreage may be released from the permit area only after reclamation phase III has been completed. The maximum performance bond liability applicable to a permit which may be released at any time prior to the completion of reclamation phase III on the entire permit area shall be calculated by multiplying the ratio between the acreage on which reclamation phase III has been completed and the total acreage in the permit area, times the total liability under performance bonds applicable to a permit, times 0.15.
The following is incorporated by reference: 30 CFR Part 800, as in effect on July 1, 2010, with the following exceptions:
