Chapter V
The 2.6 acre fill adjacent to the Tunnel Pad will remain as part of the approved post
mining plan.
d. Preparation Plant Area.
The approved backfilling and grading plan for the central complex/preparations
plant area calls for the use of 64,000 cu. yds. of washer refuse as fill. See Appendix
V-E-3.
At the conclusion of mining, prior to cessation of coal washing at the preparation
plant, 64,000 tons of refuse will be stocked for use as fill in backfilling and grading of
the preparations plant area.
Mid-Continent will disassemble the Savage garage structure, leaving the concrete
foundation as a base on which to store the refuse for use in backfilling and
grading.**
The wash plant, and other surface buildings will then be disassembled. Metal will be
sold as scrap, and the foundations rubblized. The rubble will be used as part of the
backfilling and grading to achieve post-mining contours.
The plan to achieve approximate original contour in this area is that rubble and
refuse will be deposited as necessary to achieve final contours, and the area will be
graded. See App. V-E-3 for contours and cross sections.
Rubble from the foundations will provide an estimated 50,500 cu. yds. of fill, and
refuse will provide 64,000 cu. yds.
An additional 8,700 cu. yds. topsoil will then be spread and the area reseeded with
the appropriate 8,000' seed mix.
* Note: The intention of the operator is to utilize the area for winter recreation,
including cross-country skiing, snowcat served skiing and developed lift-served
downhill skiing. The preparations plant area is essential to those plans. Near the
end of the mine life, Mid-Continent will request approval of retention of some of the
current, rather than original, contours and retention of some of the structures, for
the recreation use.
However, the current permit submittal assumes removal of all structures, backfill
and grading to return to the approximate original contours.
** As an alternative, Mid-Continent proposes the Sutey refuse conveyor belt be
used to convey material from the Sutey area back to the prep. plant area. This
would entail reversing the direction of the belt. The belt, as compared to a truck
haul, is more efficient, creates less dust and traffic and is not dependent on dry
road conditions. This would be done prior to disassembling the belt, of course.
