No problems were <br />seen with embankments or other structures. Sediment levels appeared to be well below cleanout levels, per <br />elevation values in the PAP. <br /> <br />At the King I Mine, the Clear Water Diversion Ditch (Reach 1) was inspected near the higher end of the site (near <br />the Refuse Pile) and near the lower end of the site. The ditch looked stable. <br /> <br />The Contaminated Water Intercept Ditch (Reach 10) appeared stable, and the portion next to the Refuse Pile has <br />been cleared of sediment. However, the landowner road above the ditch does not appear stable, and this will likely <br />continue to be a source of sediment to the ditch. <br /> <br />The culvert for Reach 10 that is under the haul road is a 24” CMP and is clear of sediment. The drop structure <br />below this culvert is currently stable but needs to be monitored closely for problems. <br /> <br />The outlet of the underdrain was found. It is a PVC pipe (approximately 8” diameter) in Reach 10. <br /> <br />King I surface water control structures, including a drop structure near the top of Reach 7, were maintained during <br />the inspection. <br /> <br />The following observations were made regarding King II ditches, culverts, and other structures: <br />CWD-1 (West Clearwater Ditch) below Culvert C18 (near the office) appeared stable and large enough per the <br />King II Ditch Capacities table in the PAP. <br />CWD-1 near Stacker Pad #1 appeared stable and large enough per the King II Ditch Capacities table. <br />Culvert C18 was mostly clear and met the specifications in the King II culvert capacities table in the PAP. <br />The inlet southeast of Stacker Pad 2 was protected from sediment with wattles. <br /> <br />The King II pond contained very little water and was not discharging. Sediment was approximately six feet below <br />the outlet. The concrete washout near the far end of the pond (away from the outlet) has been used recently. <br /> <br /> <br />OTHER (SPECIFY): <br />Above the Refuse Pile and Plant Growth Medium Storage Area, there are t-posts and barbed wire. The purpose of <br />this is unclear. <br /> <br />SUPPORT FACILITIES - Rule 4.04: <br />An inspection of the King II facilities revealed no problems. For example: the retaining wall above the main fan is <br />in good shape, and the chemical/fuel storage shed is clean. <br /> <br />Thistle plants on and near the facilities were rare, and many appeared to have been sprayed. Additional spraying <br />may be needed.
