July 6, 2011 C-1994-082/Yoast Mine SLB <br /> either by pushing the toe of the slide out of the drainages or rerouting the drainage around the toe of the slide. <br /> Work was underway at the Pond 012 slide area. This slide,initially occurring in 2003,has been repaired <br /> according to the plan approved in Technical Revisions No. 38,42, and 46. The trench drain was being installed <br /> along the northern pond inlet channel; a PVC pipe and gravel were being placed. The gravel will be covered with <br /> fabric,and then fill will be placed over the fabric along the toe of the slide area to assist in buttressing the slope. <br /> There were no recommendations to deviate from the approved plan at this time. <br /> The small slump that occurred at the base of the Pond 012 drainage in the shrub reestablishment area had been <br /> regraded, as had the slump that occurred on the southwest slope above Pond 012A. <br /> In the south area, a long settlement crack extends in a north/south direction parallel to YPM-1-1. This is <br /> apparently a settling crack with no major vertical or horizontal displacement; no remediation was recommended at <br /> this time. <br /> Settling cracks have also appeared on the north slope of the north pit area; again since there is no vertical or <br /> horizontal displacement,no action is warranted at this time. <br /> The Division is requiring SCC to submit a technical revision to the permit application that identifies all of the <br /> unstable areas within the permit boundary(including a map),documents their present condition based on a <br /> detailed survey, and details plans for ensuring long term stability. Documentation should also be included for <br /> those areas where further action/additional disturbance is not recommended and/or planned. <br /> In addition to the photos attached to this report,aerial coverage of all of the named features is included in the <br /> Division's April 27,2011 and June 1, 2011 inspection reports; additional on-the-ground photographs are included <br /> in the Division's June 6,2011 inspection report. <br /> Number of Partial Inspection this Fiscal Year: 1 <br /> Number of Complete Inspections this Fiscal Year: 1 <br /> Page 3 of 4 <br />
