The mine is a reclaimed surface <br />mine. As such, there are no mine personnel remaining on the site. The area has a healthy snow pack established. <br />Mine roads are not plowed or maintained during the winter months. Activity on the mine site during the winter is <br />usually limited to required hydrologic monitoring. <br />The weather at the time of the aerial inspection was clear. <br />BACKFILL and GRADING — Rule 4.14 <br />Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f); <br />Steep Slopes 4.14.2, 4.27; Handling of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6: <br />No concerns were apparent in the Neck Pit area or in the North Pit area. (Photos 9070 & 9071) <br />FISH and WILDLIFE — Rule 4.18: <br />Numerous animal tracks are observed around Pond 12. <br />Many animal tracks were observed near pond I IA. <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 />Pond 12 was photographed. Pond 12 is frozen and snow covered. Although there appears to be a small <br />area of open water on the east inlet of the pond, it was indeterminate if the pond was discharging. Snow depth in <br />the area on the pond appears to be above the middle of the 4 wire fence. Estimate snow pack is >2 feet deep. <br />Number of Partial Inspection this Fiscal Year: 4 <br />Number of Complete Inspections this Fiscal Year: 2 <br />Page 2 of 5 <br />
