The weather was warm, <br /> and the ground was dry. No MINREC, Inc. representative was present. <br /> A small number of cattle were seen onsite. <br /> AVAILABILITY OF RECORDS—Rule 5.02.4(1): <br /> A check at the Garfield County building in Glenwood Springs revealed one problem with the records for the North <br /> Thompson Creek Mine. The current permit document was not found; the one on record expired in 2018. <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 /> The following ponds were inspected: the Long Pond, Treatment Pond T-1, Treatment Pond T-2, and the Polishing <br /> Pond(Pond 9). No problems were identified with the ponds. They were all discharging, and the water <br /> discharging from Pond 9 (the bottom of the system) is relatively clear. The Refuse Pile Pond was not inspected. <br /> The Long Pond contains only a few cattails, as noted in the August inspection report. It is unclear why the number <br /> of these riparian plants has decreased. <br /> No signs of recent impacts from the mine were seen in the creek or on its banks. <br /> The aeration ditch above the Long Pond was inspected. No erosion problems were seen. <br /> Number of Partial Inspection this Fiscal Year: 1 <br /> Number of Complete Inspections this Fiscal Year: 1 <br /> Page 2 of 7 <br />
