(225 ILCS 720/3.17) (from Ch. 96 1/2, par. 7903.17)
Sec. 3.17.
Excess Spoil.
All excess spoil material resulting from surface
mining and reclamation activities shall be placed in such a manner that:
(a) spoil is transported and placed in a controlled manner in position
for concurrent compaction and in such a way to assure mass stability and
to prevent mass movement;
(b) the areas of disposal are within the bonded permit areas and all organic
matter is removed immediately prior to spoil placement;
(c) appropriate surface and internal drainage systems and diversion ditches
are used so as to prevent spoil erosion and movement;
(d) the disposal area does not contain springs, natural water courses
or wet weather seeps unless lateral drains are constructed from the wet
areas to the main underdrains in such a manner that filtration of the water
into the spoil pile will be prevented;
(e) if placed on a slope, the spoil is placed on the most moderate slope
among those on which, in the judgment of the Department, the spoil could be placed
in compliance with all the requirements of this Act, and is placed, where
possible, on, or above, a natural terrace, bench, or berm, if such placement
provides additional stability and prevents mass movement;
(f) where the toe of the spoil rests on a downslope, a rock toe buttress,
of sufficient size to prevent mass movement, is constructed;
(g) the final configuration is compatible with the natural drainage pattern
and surroundings and suitable for intended uses;
(h) design of the spoil disposal area is certified by a qualified registered
professional engineer in conformance with professional standards; and
(i) all other provisions of this Act are met.
