42.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES --
MINIMDM REQUIREMENTR OPERATION AND RECLAMATION PLANS,
2.05,6 Mitigation of Surface Coal Mining Operation Impacts. (Cont'd,)
(3) (b) (i) (Cont'd.)
All ventilation shafts and portals to be con-
structed in conjunction with the Orchard Val-
ley West Mine site development will be lo-
cated, designed, constructed, and utilized so
as to prevent or control gravity discharge of
water from the mine as required by Section
4.05.10. Protection is afforded by the natur-
al down-dip of the coal seam away from the
portal entrance, thereby preventing gravity
discharge of mine drainage.
As discussed in previous sections, CWI commit-
ted to water rights protection strategy
throughout the permit area. All of the pro-
visions of that plan remain in effect.
The Orchard Valley k'est Mine site has small
disturbed acreage. Appropriate sedimentation
ponds and site drainage are designed to pro-
• tect the quantity of surface and groundwater
both within the proposed and adjacent area
from adverse effects from proposed coal mining
~,-0, activities. Where protection cannot be en-
sured, alternative sources of water are avail-
able as stated in the k'ater Protection Strate-
gy
A small landslide was identified above the in-
let structure of the culvert. A rock toe but-
tress approximately 40 feet high, 100 feet
wide, and 30 feet in depth was constructed at
...the base of the slide from sandstone and ba-
salt boulders obtained during excavation of
the mine bench. The slope of the buttress was
approximately 1:1 and met, but did not ob-
struct, the stream channel. A french drain
was constructed across the top of the land-
slide along the cut bank of the "Blouch Road"
to drain flows believed to be contributed by
the "E" coal seam and overlying strata. The
drain was approximately 5 feet in depth, two
