into original road surface, if possible, at the head scarp and become shallower as they <br />. approach the ditch. <br />3. Regrade the toe bulge <br />4. Lightly reconfigure the head scarp <br />5. Seed and control weeds <br />6. Ongoing visual inspection <br />Status: Work was initiated in 2011 and is expected to be completed in 2012. <br />• Pond 016 Slide Area <br />— Problem: The Pond 016 /016A area is located at the base of a mapped, pre - mining <br />mudflow encompassing the PM -2A drainage basin. <br />Remediation: An approved remediation plan is inplace and was implemented in 2011. <br />— Status: Work began in 2011 and is expected to be completed in 2012. <br />• Pond 017 /Stock Tank T -25 Area <br />— Problem: There is instability (slump /small slide) in the undisturbed area above Pond 017. <br />Stock Pond T -25 overflowed and the drainage channel above and below the pond was <br />damaged. <br />— Remediation: The proposed remediation of the area is to remove Stock Pond T -25 and to <br />repair the drainage channel PM -1. The road along the edge of Pond 017 will have water <br />ditched on the upper side and piped under the access road. <br />— Status: Work is expected to be initiated in 2012. <br />• • Pond 006 Area Slumps <br />— Problem: There are several slumps upslope and around Pond 006. This area was <br />identified as a historically active landslide area (prior to mining). <br />— Remediation: The area was regraded, sloped and revegetated during the narrowing of the <br />main entrance road for final reclamation. <br />— Status: Work was completed in 2011. <br />r1 <br />U <br />AREAS IDENTIFIED BUT NOT TO BE REPAIRED /STABILIZED <br />There are numerous slumps and highwall settlement cracks showing up within the II -W <br />disturbed areas as shown on the attached map, 2011 Areas of Instability. During the July site <br />visit and inspection, it was decided that if the slump /settlement crack did not threaten any <br />permanent structures or drainage channels or if repair would cause more disturbance than <br />required to actually remediate the site, the sites would be left to remediate /stabilize themselves. <br />The areas will be visually inspected each spring and shown on the Rill & Gully Map. An <br />explanation of these areas is included in the attached report by Jill Carlson (CGS). <br />TR -76 20 -E -2 11 /11 <br />
