Ed Ogrodny of Mountain Coal Company (MCC) accompanied the inspection. There was heavy rain <br />before, during and after the inspection. The mine was active. <br /> <br />HYDROLOGIC BALANCE - Rule 4.05 <br />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; <br />Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; <br />Drainage – Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br /> Due to a combination of factors (heavy winter snowpack on the higher ground south of the facilities area, <br />warming spring temperatures, and heavy rain), the site was very wet, with saturated ground in many places and <br />rising levels in the sediment ponds. No ponds were discharging, although water was being pumped from the RPE <br />and MB5E ponds to the adjudicated in-mine sealed sump water storage area, and from the SG1 pond to the Mine <br />water treatment pond. No ponds were discharging, nor were they expected to. Ditches and culverts around the site <br />were clear and working as designed. <br /> <br />GENERAL MINE PLAN COMPLIANCE: <br /> The longwall was mining in the LWE8 panel, at around cross-cuts 20 on the LWE8 Headgate. <br />Development mining had progressed to around cross-cut 22 in the Sunset Mains South and to cross-cut 18 in the <br />LWSST1 Headgate, crossing from the Mount Gunnison Fuel Company lease area into Federal Lease C -1362. <br />The Run-of-Mine coal stockpile was still rather large, although it had remained within the stockpile <br />footprint and trains were apparently running frequently. <br /> <br />PROCESSING WASTE/COAL MINE WASTE PILES – Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br /> Processing waste from the wash plant continued to be stored temporarily on the surface of the RPE. Wet <br />conditions meant that access to the RPEE was not practical . Although the volume of the temporary pile was large,
