An inspection of this area was conducted on May 24, 2001. No subsidence features <br />were identified during this inspection with the possible exception of some tiny (1/8" to 1/4") <br />cracks along an old section of 2-track road. These cracks will be monitored regularly and <br />the landowner will watch them as well. <br />Mining has been completed beneath the Dunn/Ute Mountain Ute Tribe Lease. OSM has <br />been checking, measuring, photographing and mapping these cracks on a quarterly basis. <br />These cracks look much like the cracks which are not under OSM jurisdiction. As per <br />OSM suggestion, we repaired two cracks which intersected atwo-track road paralleling the <br />east-west fence on the south side of the property. The most recent OSM inspection <br />revealed that the cracks repaired by NKC are still in good shape and the other cracks are <br />healing nicely. If this trend continues, they are willing to release the bond following the <br />next quarterly inspection. <br />The other areas where pillars have been extracted are Sections No. 4 West, 7 South, 6 <br />South and 5 South/1 Left. The 7 South and 6 South area exhibits normal subsidence <br />tension cracks extending north from a point about 300 feet south of the Huntington Ditch. <br />This area of the ditch has been replaced with a buried pipeline. Some cracks appear to <br />have crossed the pipeline with no apparent consequences. The landowner is monitoring <br />the situation closely. <br />Call if you hav/~~~lpy questions. <br />Sincerely, <br />To/m B <br />Planning & Engineering <br />National King Coal, LLC <br />
