The Life of Mine Road was watered by <br />trucks during the inspection. Some dust was created by the gully repair operations in the Oak Gulch drainage. <br />EXCESS SPOIL and DEVELOPMENT WASTE - Rule 4.090 ?Placement; Drainage Control; Surface <br />Stabilization: <br />Construction of Horse Gulch Fill was observed. The Molly Brown dragline was casting spoil, and three <br />scrapers were placing topsoil between the first and second benches. No compliance issues were detected. <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 />Several sediment ponds on the site were inspected, and the following maintenance issues were observed: <br />• Sediment level markers appear to be missing for West Pyeatt #1, East Pyeatt#1, East Pyeatt#2, East <br />Pyeatt#3, Oak #1, Oak #2, and East Middle Flume. <br />• Sediment removal is needed from Oak #1 and possibly Oak #2. <br />Repairs have been made to the dam at West Pyeatt #1 pond. Sediment in East Pyeatt #1 has been cleaned out, but <br />significant disturbed area around pond, as well as sediment sources in the watershed (F Pit, Haul Road) will <br />require frequent cleaning in the future. Sediment has also been removed from East Middle Flume pond. <br />Animal burrow holes were observed on the Coyote Pond embankment, but do not appear to pose a threat to the <br />relatively large structure. <br />The inspection indicated no water quality problems, such as oil and grease or turbid water, at any of the pond <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 1 <br />Page 2 of 6
