Near the north end of the site <br />(approximately a quarter mile from the boundary), the second ditch from the top contained a blowout that is <br />causing a large rill, approximately one foot deep and four feet wide. Another blowout was observed in the next <br />contour ditch down the hill. Later in the inspection, a blowout was observed near one of the riprap lined channels. <br />These should be monitored and possibly repaired this summer. <br /> <br />Moffat Pond was slowly discharging. There was a sulfuric smell from the discharge at the Moffat Pond. No <br />problems were observed with the embankment or other pond features. However, Chris Miller indicated that the <br />primary spillway pipe is rusted and may be replaced in the future. <br /> <br /> <br />GENERAL MINE PLAN COMPLANCE: <br />The mine was found to be in general compliance with the permit. <br /> <br />The fence at the Moffat Pond remains damaged near the southwest corner. Posts have been bent and the wires are <br />lying on the ground. Chris Miller indicated that the work will be performed when the ground dries out. <br /> <br />Number of Partial Inspection this Fiscal Year: 6 <br />Number of Complete Inspections this Fiscal Year: 3 <br /> <br />26 <br />Page of <br /> <br /> <br />
