<br />• t~ iapaa <br />- Evidence of Instability or Huth Cut and Fill P~baril®arts <br />Robert W. Ttaanp,on's 19T7 report identified potential concerns regarding <br />cut and fill construction activities. The reports are on file with the <br />CMLRD and suggest instability existed prior to construction, especially in <br />areas where steep, north facing slopes were present. Sun Coal Company <br />constructed the road in accordance with the approved plan (76-61) and <br />installed appropriate erosion and sedimentation control structures, <br />ditches and culverts wherever necessary. In natural areas subject to <br />failure as defined by Thompson, ERTEC, Four Consultants and EnecoTech and <br />when failure occured debris from the road was removed and wherever <br />practicable landslide areas were repaired. Areas which failed due to <br />activities outside the control of San Coal Company were either repaired by <br />San or left to be reclaimed by the larxiowner. <br />Prior to and during mining, several areas were identified to be susceptible <br />to failure. In addition, several areas appear to be unstable as a result <br />of CMLRD decision to require outslope drainage control methods. Areas <br />where instablity has been noted include: <br />- an area above the reclaimed coal crushing and storage area; <br />- an area below Mr. Eilts' oil well; <br />• - an area between culvert 5 and culvert 6; <br />- an area above the road between culverts 6 through 10; <br />- the outslope between culverts 6 and 10. <br />The above report is sumbitted in response to the outstanding issues <br />related to the Bond Release Application aryl represents Slug Coal Company's <br />certification requirements specified by CMLRD statues aryl regulations. <br />u <br />_ 214 _ (Rev. 5/86} <br />
