The o13 spoil pile located immediately south of the mine plan area in Section 24, Township 5 North, Range 86 West, has not been used since October, 1979 and has been graded out to a stable slope. This pile is complete, will never be used again, and was approved in Energy Fuels' Permit 76-16. As more fully discussed under Rules 2.05.3 (6)(b) and 4.14.1 (1), this permanent overburden stockpile is not needed to achieve approximate original contour. Sackfilled material will not adversely affect the ground water as demonstrated by the discussion and testing results for spoil mater- ial set forth under Rules 4.05.12, 2.04.6 and 2.05.6(3). The postmining land use, which will be rangeland, will be promoted by an undulating surface which will minimize erosion and maximize water retention, yet minimize the passibility of sliding. No cut and fill terraces will be incorporated in the backfilling and grading. There will be no new boxcuts ar initial cuts and so no additlanal spoil will be permanently disposed of outside the mined area. This mining operation is already in a haulback and direct backfilling state which allows all spoil to remain in the mined out area. There are no new mine areas which will need to be developed ehrough the use of a boxcut. The temporary spoil piles located adjacent to the Middle Creek Underground Mine highwall will be used to backfill the portal area upon completion of the underground mining. The overburden in these
