Oklahoma § 45-754.1 - Spoil material - Placement

§ 45-754.1. Spoil material - Placement

The operator shall place all excess spoil material resulting

from coal surface mining and reclamation activities in such a manner

that:

1. 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;

2. The areas of disposal are within the bonded permit areas and

all organic matter shall be removed immediately prior to spoil

placement;

3. Appropriate surface and internal drainage systems and

diversion ditches are used so as to prevent spoil erosion and

movement;

4. 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;

5. If placed on a slope, the spoil is placed upon the most

moderate slope among those upon which, in the judgment of the

Department, the spoil could be placed in compliance with all the

requirements of this act, and shall be placed, where possible, upon,

or above, a natural terrace, bench, or berm, if such placement

provides additional stability and prevents mass movement;

6. Where the toe of the spoil rests on a downslope, a rock toe

buttress, of sufficient size to prevent mass movement, is

constructed;

7. The final configuration is compatible with the natural

drainage pattern and surroundings and suitable for intended uses;

8. Design of the spoil disposal area is certified by a

qualified registered professional engineer in conformance with

professional standards; and

9. All other provisions of this act are met.
