No company representative accompanied me on the inspection. <br />The North Thompson Creek Mine is a reclaimed site that has undergone a full Phase III Bond Release on all but <br />4.1 acres. The weather was warm and cloudy and there were intermittent rain showers. <br /> <br />AVAILABILITY OF RECORDS – Rule 5.02.4(1): <br />- All of the required records were available in the Clerk and Recorder’s Office at the Garfield County Courthouse. <br />Please see the Availability of Records form at the end of this inspection report for more details. <br /> <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 Monitoring <br />4.05.13; Surface Water Monitoring 4.05.13; Drainage – Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, <br />4.05.9; Stream Buffer Zones 4.05.18: <br />- There was discharge coming from both the Mine #1 and Mine #3 pipes at the time of the inspection. This <br />discharge flows into the Long Pond. The long pond was well vegetated and stable and no erosional problems were <br />noted in the pond. <br />-Treatment Ponds #1 and #2 were both full and discharging at the time of the inspection. TP #1 discharges into TP <br />#2 and TP #2 discharges into pond P-9. Both pond embankments were well vegetated and stable and no erosional <br />problems were noted at the time of the inspection. There was no evidence of any iron precipitation (“yellow boy”) <br />in or around either of the treatment ponds. <br />- Ponds P-9 and the Refuse Pile Pond are both used for water storage. Pond P-9 was full and water was <br />discharging into the Refuse Pile Pond (which had several feet of water in it). Both Pond embankments were well <br />vegetated and stable and no erosional problems were noted on either pond at the time of the inspection. <br />- The discharge from the Mine #3 was entering the manhole along the Forest Service Road. The discharge then <br />enters a PVC pipe and discharges into the Long Pond. <br /> <br />
