Sandra Brown, Brock Bowles, and Stephanie <br />Reigh from the DRMS Denver office were also present. No representative from McClane Canyon Mine was <br />present during the inspection; however, we did speak with April Schultz HR/Administrative Assistant at the <br />McClane Canyon Mine office prior to the inspection. Weather conditions were cloudy and cool. Ground <br />conditions were damp and muddy in some areas particularly around the portals area. Coal was not being conveyed <br />from the mine and the mine had shut down their operations on 12/9/10 according to April Schultz. <br />AVAILABILITY OF RECORDS — Rule 5.02.4(1): <br />The availability of records was checked at the mine office on the afternoon of 12/9. The third quarter 2010 <br />discharge monitoring records and the third quarter sediment pond inspection reports were not on file. Also the <br />Insurance Certificate has expired and a current certificate needs to be added to the files. Please update the records <br />files accordingly. All other required records were available for review at the time of this complete inspection. See <br />the attached records checklist at the end of this inspection report. <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, <br />4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring <br />4.05.13; Drainage — Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />A rock fall occurred recently (just prior to this inspection according to site personnel) at the location of the large <br />diversion structure located in the drainage behind the exhaust fan.
