Katryna Snowden of SCC accompanied the <br />inspection. The weather was raining. The mine site was wet and muddy. The area has received rain over the last <br />week. The roads were muddy and soft. Light use roads draining to the west were not driven due to the muddy <br />conditions. <br />FISH and WILDLIFE Rule 4.18: <br /> Blue grouse were observed at the top of the reclaimed north pit. Three Columbian sharp tailed grouse <br />were flushed to the east of Shrub plot SP06-1. <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 /> Pond 010 was inspected. The embankment is well vegetated. SCC plans to enact weed control measures <br />on the Jointed goatgrass patches on the embankment this fall. Jointed goatgrass is a winter annual, so fall <br />treatment is recommended by the local weed agency. <br /> <br />Pond 010 was discharging 0,01 on the staff gauge. SCC had noted some bank cutting near the Pond 010 riser, so <br />bentonite was used to seal up this area. The bentonite appears to be working effectively. <br /> <br />Pond 11A was accessed. SCC has completed repairs to the inlet of pond 11A and YPM-9. This area has been <br />shaped, and rip-rapped. This repair appears that it should hold up to heavy runoff conditions. Pond 11A was not <br />discharging, but was holding a pool of water approximately 1 foot below the discharge elevation on the riser. <br /> <br />Stock tank ST-1 was holding a pool of water but was not discharging. Drainage YPM 1-1 was walked to its end <br />southward. All previously noted gabions have now been appropriately wired shut. <br /> <br />Number of Partial Inspection this Fiscal Year: 2 <br />Number of Complete Inspections this Fiscal Year: 1 <br /> <br />25 <br />Page of <br /> <br /> <br />
