Skies were clear throughout the inspection, and the <br />temperature was warm. I was accompanied on the inspection by Tom Bird, Manager of Coal <br />Services for the King Coal Mine. <br />The timing of the inspection was selected to coincide with geotechnical field investigations being <br />conducted at the King I site. As part of the abatement for NOV CV- 2012 -003, issued on April <br />11, 2012, GCCE has contracted with Trautner Geotech, a Durango firm, to evaluate the site <br />conditions and the coal mine waste material placed as backfill at the King I tipple highwall and <br />portal bench (Photo 1). <br />EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09 <br />Placement, Drainage Control; Surface Stabilization: <br />• The Trautner drill rig was just leaving the King I site just as I arrived. Although Mr. Bird <br />and I were unable to observe the drilling activities as they occurred, the boring sites were <br />clearly visible (Photo 2). Six test borings (TB -1 thru TB -6), which appeared to have been <br />drilled through the coal mine waste and into the material below, had been fitted with a PVC <br />pipe, which was capped and extended above the surface of the backfill. <br />• Mr. Bird said that Joe Bowden, of CDS Laboratories, had been also on site to collect samples <br />of the coal mine waste for chemical analysis. <br />• We also inspected the approved coal mine waste pile located at the King I site. The clean <br />water diversion ditch, which flows along the northern side of the pile, was clear and well - <br />maintained (Photos 3 and 4). Surface runoff from top of the pile is captured by the collection <br />ditch that flows along the pile's south side. Both ditches are confined to rock -lined channels <br />for the steep drop down the face of the waste pile (Photo 3). <br />• A number of dump loads of coal mine waste had been deposited along the northern <br />(upstream) edge of the pile (Photo 4). <br />Number of Partial Inspection this Fiscal Year: 8 <br />Number of Complete Inspections this Fiscal Year: 3 Page 2 of 7 <br />
