July 29, 2014 C- 1981 - 035 /King Coal Mine LDS <br />spillways or the embankment. <br />Beside the haul road some piles of material (gravel and limestone) were deposited. The east (down slope) <br />sides of the piles were protected by a silt fence. <br />In front of the portals, beneath the conveyor, is a depression that collects water (but was not originally <br />intended). A short section of culvert had been used to convey water from the depression down the slope. There are <br />two issues that are contributing to erosion and should be addressed: <br />1. The culvert outlets onto a bare slope and is eroding the soil. My Wymore described plans to <br />extend a rock armored drain from below up to the culvert outlet. <br />2. The drain from the conveyor is a short section of downpipe directly above the middle of the <br />culvert section. When the conveyor structure is washed and water drains from the structure it <br />drops directly onto the culvert and splashes around the surrounding area. The downdrain should <br />be extended, possibly back towards the inlet of the culvert, to minimize the impact of the <br />water. <br />On the east side of the coal stockpile a drainage ditch beside the road had filled in and become indistinct <br />as it crossed near to the stockpile. The ditch should be re- established to ensure effective drainage. This will <br />alleviate pressure on the sump behind the fuel storage shed which is currently receiving more runoff than is <br />appropriate. <br />GENERAL MINE PLAN COMPLIANCE: <br />It was noted in previous inspection reports that the coal stockpile volume had grown to such an extent that <br />it had exceeded the pad and had threatened the adjacent clean water ditch. At the time of this inspection, the <br />transport issues that led to the enormous stockpile volume had been overcome and the stockpile volume had been <br />greatly reduced. Still, some spilled coal remained to be cleaned up and returned to the stockpile area. This work <br />was in progress. <br />ROADS — Rule 4.03 <br />Construction 4.03.1(3)/4.03.2(3); Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance 4.031. 1(5) and <br />(6)/4.03.2(5) and (6); Reclamation 4.03.1(7)/4.03.2(7): <br />The haul road from the county road conveys street legal traffic only; as such, there is no requirement for a <br />berm along the side of the road. The road was in good shape. <br />TOPSOIL — Rule 4.06 <br />Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution 4.06.4: <br />The topsoil stockpile at the north east end of the mine site was inspected. A considerable infestation of <br />thistle was observed. The pictures suggest that the plants are Musk Thistle Carduus nutans, which is a B -list <br />noxious weed in Colorado and should be controlled. The Colorado State University extension service publishes <br />a factsheet with details about the plant and suggestions for its control. The factsheet can be viewed online: <br />http://www.ext.colostate.edu/pubs/natres/03 102.html <br />(A plant that was suspected as a Tamarisk /Salt Cedar Tamariix spp. during the inspection appears to be a <br />species of Juniper on close inspection of the pictures.) <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 3 of 15 <br />
