RE: Grand Mesa fuse Disposal Fill
Grand Mesa Coal Company's completion of the proposed, but as yet unapproved,
strip pit refuse fill could seriously complicate their situation. As S
discussed in my memo of April 3, 1980, it is imperative that no coal
containing refuse be placed beneath the water table. In order to assure
that the water table has not invaded the already placed refuse, the
applicant will have to install and monitor an appropriately located set
of test wells. The applicant should install at least three test well
stand pipes, ttro approximately 25 feet outside the original strip pit
boundaries, and one centrally located within the existing fill. These
stand pipes should extend at least five feet beneath the bottom elevation
of the strip pit. These wells should be monitored at Zeast weekly,
from mid-May through mid-July, during which the annual water table high
stand should occur.
