Weather varied during the <br />inspection, from sunny and warm to rain and snow showers. Locally, weather patterns continue with cooler <br />temperatures and higher than normal precipitation. The Yampa River basin is at 201 % of normal. At the mine <br />site, there is still a considerable amount of snow in the upper Pond 016 and 017 watersheds. <br />FISH and WILDLIFE — Rule 4.18: <br />The Columbian Sharp- Tailed Grouse lek near the intersection of Haul Roads A and J and the Ridgeline Access <br />Road was visited the morning of May 17th, at approximately 6 a.m. There were approximately 20 -30 birds <br />dancing and drumming. Harriers, Red - Tailed Hawks, several songbirds, elk, and deer were observed throughout <br />the permit area. <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, <br />4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring <br />4.05.13; Drainage — Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />Pond 006 was discharging somewhat cloudy water, but appeared to be well within the 0.5 mUl settleable solids <br />limitation. The embankment and outfall area of the pond were stable. There was still a good amount of water <br />running down through the 006 Gulch, but snowmelt was nearly complete in this drainage. <br />Pond 009 was discharging fairly clear water. The embankment of Pond 009 was stable, but the emergency <br />spillway still needs supplemental rip rap to meet design criteria. The rock in the spillway has weathered and <br />fractured. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 2of15 <br />
