September 28,2011 C-1994-082/Yoast Mine SLB <br /> All repair work in the Pond 012 slide repair area has been completed in accordance with the approved plan,with <br /> the exception of seeding of the south slope. The area will be seeded next year, after a year of observation to <br /> ensure that repaired slopes remain stable. <br /> The operator regraded a small settling crack on the east side of the YPM 5-1 drainage. It did not appear to have <br /> been seeded yet, and should be reseeded this fall. <br /> Scarp regrading of the Neck Pit slide area was complete,but needed to be seeded. Seeding needs to be completed <br /> this fall. The operator had constructed toe drains in the slide area,but they will need to be reworked for positive <br /> drainage. The current configuration retains three low spots where water will pool and cause the slide area to <br /> resaturate. The operator will need to achieve a lower grade so that water runs from the slide into the Haul Road A <br /> ditch. It might be necessary to construct a subsurface drain since excavation to the required depth would result in <br /> either a deep, steep-sided trench or require removal of a large amount of material between the ditch and the slide. <br /> Removal of the toe material to drain the low area would not be recommended as this material is currently <br /> buttressing the slide. <br /> ENFORCEMENT ACTIONS/COMPLIANCE <br /> No enforcement actions were initiated as a result of this inspection,nor are any pending. <br /> Number of Partial Inspection this Fiscal Year: 5 <br /> Number of Complete Inspections this Fiscal Year: 1 <br /> Page 3 of 7 <br />
