RE: Coal Basin Reclamation
Dear Mr. Lewicki:
We have received your letter of May 21, 1998, and offer the following comments:
Regarding the concrete rubble disposal: As we discussed, this contract is currently in progress.
The project was bid in the fall of 1997, with a copy of the project description being provided to
Resources at that time. Initial disposal operations have already begun in this area. Discussions
with our contractor indicate that a minimum additional charge of $50,000 would be necessary to
accomplish the change which has been suggested. This is half again as much as the original
contract price. Our current cost projections do not allow for this cost increase.
Discussions with earth moving contractors indicate that changing the north facing slope of the
rubble disposal area from the design slope of 5H:1V to 3H:1V will create added difficulties, and
thus increased costs, for the disposal of coal refuse, cover material and topsoil. Further,
revegetation potential on shallower slopes is greater, while erosion potential is increased on a
steeper slope. The increased cost of hauling the refuse to the steepened rubble may make the
Huntsman project infeasible.
Should the Huntsman Project not be completed, other methods of generating sufficient material to
bury the refuse, as provided in Resources permit, will need to be explored. These alternatives
will need to be funded by the Liquidation plan, rather than through completion of the Huntsman
Project. It follows that, regardless of the source of cover material, a similar increase in cost
would be realized if the burial operation is funded by the liquidation plan.
The demolition contractor is currently estimating, based upon the amount of work presently
completed and the volume of disposal area used, that the toe of the rubble when completed at the
current design of a 5H:1V slope will be approximately fifty to sixty feet further south than
previously projected. If this projection is accurate, then additional flat areas at the current yard
elevation would be created.
