May 22, 2012 C- 1981 - 019 /Colowyo Coal Mine RDZ <br />Other observations concerning the ponds: <br />• Prospect pond has a large delta of sediment, which appears to be growing. As noted before, this sediment <br />is slated for cleaning in 2012. <br />West Taylor Pond also has a large delta of sediment, which should be removed in 2012. <br />The culvert above the flume for the West Pit Pond has been repaired. <br />The erosion problem in Prospect Ditch was observed again. Some of the channel below the eroding section was <br />observed and appears to be in satisfactory condition. <br />The perimeter ditch above Prospect Pond was found to be in good shape. <br />GENERAL MINE PLAN COMPLANCE: <br />The mine was found to be in general compliance with the permit. <br />ROADS — Rule 4.03: <br />All haul roads were in good shape. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />h1 the recently reclaimed areas of West Pit, vegetation is still sparse in many areas, but some new growth was <br />observed. <br />In the East Pit reclamation area, pennycress and other vegetation is emerging in areas seeded in the spring of 2011. <br />Some areas exhibited very good surface roughening. <br />Also in the East Pit area, contour ditches have been added and existing ditches have been repaired. A slope along <br />one of the new ditches was measured at two percent, which is the specification. <br />Near the West Taylor Pond, weeds were observed on both sides of the creek above the pond: cheat grass was seen <br />on the west side, Houndstongue was seen on the east side. <br />SLIDES and DAMAGE - Rule 4.12: <br />The slump above the East Taylor Pond has appeared to stabilize. It is recommended that CCC staff check the <br />grade of the contour ditch above this area to determine if a low spot is the cause of a seep, which could have <br />created the slump. <br />SUPPORT FACILITIES - Rule 4.04: <br />No problems were identified at the facilities area. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 3 of 12 <br />
