V. Ground water Hydrology - Rules 2.04.5, 2.04.7, 2.05.6(3) and 4.05
Ground water information submitted in the original permit application
adequately addressed ground water conditions in the permit and proposed
permit revision areas. The specific findings included in the narrative
in the July, 1987 Findings Document (Renewal) are applicable to the area
of proposed PR No. 2.
The proposed operation is in compliance with the requirements of this
section.
VI. Surface Water Hydrology - Rules 2.04.5, 2.04.7, 2.05.3(4), 2.05.6(3
No surface disturbance is proposed within the area of PR No. 2. Mining
of the area will be entirely accomplished thru extension of underground
workings from the present King Coal Mine. Since the proposed future
operation of the mine will be conducted using the area currently
disturbed, no changes are proposed in either the current surface water
and sediment control system for the mine or the surface water monitoring
plan. As a result, the narrative under this section of the July, 1981
Findings Document (Renewal) remains applicable.
The proposed expansion of the permit area to include PR No. 2, however,
will extend the mining beneath Pine Gulch, an ephemeral stream arainage
located in the southeast part of Section 32, Township 35 North, Range
11 West. This extension of mining could create some potential for impact
on surface water resources of this drainage and areas downstream.
Pine Gulch extends southwest approximately three miles from the expanded
permit area to its confluence with Hay Gulch. The proposed mining plan
for PR No. 2, however, includes the employment of elongated pillars to
support all passages beneath Pine Gulch, and the mine is committed not to
extract these pillars upon final retreat. Consequently, the risk of
surface subsidence of Pine Gulch as a result of the mining is minimized.
There should be no subsidence related fracturing of the roof rock of the
mine beneath the drainage, no potential created for loss of surface water
into the underlying workings, and, therefore, no likelihood of
significant reduction or interruption of surface water quantity in
Pine Gulch as a result of the mining. With the absence of any surface
disturbance that would drain the Pine Gulch and with the prevention of
any contact of the surface water with coal or associated rock freshly
exposed by the mining, there will be no adverse impact of the operation
on the quality of surface water in Pine Gulch.
The proposed operation is in compliance with the requirements of this
section.
