The worst-case reclamation scenario (i.e., largest reclamation liability) occurs at the conclusion of <br />mining, since most of the Whirlwind bench and a portion of the waste embankment will need to be <br />reclaimed. The entire 0.99-acre area at the Packrat portal will need to be reclaimed. The ventilation <br />shafts will also be reclaimed at the conclusion of mining. Each portion of the reclamation is discussed <br />in the sections that follow. <br />The reclamation timetable is shown in Section 2 in Table E-1 and the costs for the worst-case scenario <br />are calculated in Exhibit L: flteclamation Costs. <br />2. Reclamation Timetable <br />The reclamation timetable below is based on the projections for the mine and the amount of <br />reclamation that is needed after mine shutdown. Once the mine is permanently shut down, the <br />reclamation is expected to take approximately 24 months. The initial 18 months of reclamation <br />consists of sealing the Whirlwind decline and monitoring the water pool that will form above the seal. <br />• <br />Whirlwind Mine 07 (rev.
