May 21, 2012 C- 1994- 082/Yoast Mine SLB <br />needed repair work where downcutting had occurred in the water bar crossing. <br />The surge strictures constructed in the north pit area last fall were in good condition. The structures were all dry, <br />but it was apparent that water had been temporarily impounded during runoff The ditches between the strictures <br />were in good condition. There was a gully along the reclaimed temporary roadway to the surge strictures, <br />extending about 75' westward from the property line fence separating the north mine area. <br />REVEGETATION Rule 4.15 Vegetative Cover; Timing: <br />There was a considerable amount of houndstongue and thistle around the Pond 012 slide repair area and <br />along LU -5, near Pond 013. Vegetation in the southern section of the permit area looked good; the weed spraying <br />done last year in this area appeared to have been effective thus far. <br />The shrubs planted between Ponds 012 and 012A looked very healthy and were leafing out nicely. The shrubs <br />planted in the north pit last fall also looked good; there appeared to be a high survival rate. There was still a fair <br />amount of weeds (houndstongue and thistle) that will need to be treated in this plot this year <br />SLIDES and DAMAGE - Rule 4.12: <br />The Pond 012 slide repair area was stable, with no sign of any movement since the repair work was <br />completed. There was also very little erosion on the repaired slope face. <br />A crack has developed on the Pond 013 slide, roughly parallel to the original scarp line, and approximately 20' <br />from the upper edge of the scarp. The crack is roughly 34 inches wide, and appears to be shallow in depth. <br />The neck pit slide appeared to be stable, with no evidence of any movement since the scarp area grading occurred. <br />There was standing water on the west side of the shrub enclosure. An underdrain in this area may be warranted to <br />prevent further movement. The Division will consult with CGS on this area during the next CGS evaluation. <br />DOCUMENTS RECEIVED — 1S Quarter DMRs and pond inspection reports. <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: 12 <br />Number of Complete Inspections this Fiscal Year: 4 <br />Page 3 of 7 <br />
