The weather conditions were sunny at the time of <br />the flight and the upper portal areas had a significant amount of snow cover. All five portal areas, the lamp -house <br />and the office area were photographed. The permit for this mine was revoked and the bond was forfeited. The <br />reclamation was completed by the DRMS. <br />HYDROLOGIC BALANCE - Rule 4.05 Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, <br />4.05.6; Discharge Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water <br />Monitoring 4.05.13; Surface Water Monitoring 4.05.13; Drainage — Acid and Toxic Materials 4.05.8; <br />Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />The two culverts in Coal Creek (below the Sutey Pile and at the confluence with Dutch Creek) appear to <br />be functioning properly and Coal Creek appears to be within the channel. The road over the culvert in Dutch <br />Creek by the lamp -house appears to have cracks (photo 1). This should be checked during the next ground <br />inspection. <br />The two ponds south of the Sutey Pile contain water and appear to be stable. The eastern pond has a large <br />sediment plume extending from the inlet channel. <br />ROADS — Rule 4.03 Construction 4.03.1(3)/4.03.2(3) Drainage 4.03.1(4)/4.03.2(4) Surfacing and <br />Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) Reclamation 4.03.1(7)/4.03.2(7): <br />A land slide was seen about .8 miles east of the office on the mine access road that has deposited some soil <br />on the road, but the road appears to be passable (photo 2). It is unclear from the maps if this area is within the <br />permit boundary. <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 1 <br />Page 2 of 5 <br />
