HYDROLOGIC BALANCE - Rule 4.05
Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures
4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13;
Surface Water Monitoring 4.05.13; Drainage — Acid and Toxic Materials 4.05.8; Impoundments
4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
• Ground conditions were dry throughout the permit area. The region has not received any
significant precipitation in recent weeks.
• The King 11 sediment pond was dry (Photo 3). Pond inslopes and the embankment outslopes
were reasonably well vegetated, although a patch of Cheatgrass is gaining a foothold on the
outslope.
• A mine employee was pulling grass by hand from the King II West Clear Water diversion
ditch.
• Stretches of the King 11 East Clear Water diversion ditch were in need of maintenance; the
vegetation has grown to the point where flow may be impeded (Photo 4). Mr. Wymore said
that likely a skid -steer would be used to clean out the ditch, restoring it to the design
configuration (as shown on Map King 11- 007A).
• The rocks for a segment of the riprapped West Clear Water diversion ditch appeared to have
been disturbed, and no longer matched the trapezoidal configuration that was visible in the
stretch immediately upstream - the rocks need to be rearranged to provide the approved
channel dimensions, as shown on Map King II -007A.
• At King I, the West Pond was completely dry (Photo 5), and the East pond (Photo 6) held a
shallow pool of water. Emergency spillways for both ponds were clear.
TOPSOIL — Rule 4.06
Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution
4.06.4:
• The King 11 topsoil stockpile was well vegetated (Photo 7) with a variety of species,
including blue flax and rabbit brush.
• At the southern end of the topsoil stockpile, an outlet in the protective berm is constructed to
allow accumulated water to drain away from the site. Some vegetation has grown in this
outlet (spillway), which might impede its ability to drain properly.
• At King I, the stockpile of fill / soil at the upper end of the coal mine waste bank needs to be
seeded this year, when the time is appropriate (Photo 8).
EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09
Placement; Drainage Control; Surface Stabilization:
The Coal Mine Waste Pile at King I is constructed in a Valley -Fill configuration; thus, Rules
4.09.1 and 4.09.2 apply (except as superseded by 4.10).
The Clean Water Diversion Ditch that runs along the northern side of the waste pile is to be
relocated higher on the hillside to allow for the placement of coal mine waste across the full
width of the valley (Photo 9). Design details provided in Appendix 11(1) must be adhered to
as the ditch is relocated.
