and the unnamed drainage between the Sanborn Creek and Coal Gulch drainages, above Springs 7 and 9 <br />respectively. <br />An analysis of the previous results of this monitoring program suggests there was no identified movement <br />in the slide features either naturally or associated with mining activities. <br />Beginning with the year 2002, PR -04 modified and removed the Sanborn Creek Mine spring and seep <br />sampling program but the subsidence monitoring of the three mass movement areas in the vicinity of the <br />Sanborn Creek Mine continued. Previously, OMLLC employee Mr. Tom Anderson had participated in <br />the conduct of the required inspections. To provide continuity with respect to the specific areas to be <br />inspected and to provide a perspective regarding any perceived changes to any of the mass movement <br />features Mr. Anderson accompanied the undersigned during the 2002 inspections. The 2002 monitoring <br />indicated there were no visible signs of recent mass movement and no additional new mass movement <br />features noted. <br />Elk Creek Mine <br />PR -05 required additional monitoring of areas overlying the Elk Creek Mine (see the PAP discussion <br />found on page 2.05-104) where regularly traveled roads are located below historic landslides in the Bear <br />Creek drainage. Mr. Doug Smith, Oxbow Chief Engineer, accompanied the undersigned on the 2015 <br />inspections. The monitoring conducted in 2015 indicated no unusual movement of the slide features. <br />Minor tension cracks remain in sandstone outcrops associated with Panel #1. No additional tension <br />cracks were observed in the surface of the Bear Creek two track ranch road. <br />Background Information <br />During 2002, Mr. Anderson also accompanied the undersigned to a number of areas visible in the permit <br />area located within the Elk Creek, Bear Creek and Hubbard Creek drainages. These drainages are steep, <br />deeply incised and contain a number of pre-existing slides and slump features. No visible signs of recent <br />mass movementwas apparent and no new mass movement features were noted during the year 2002 <br />inspections. <br />The 2003 — 2015 inspections indicated similar results. No significant indication of recent mass <br />movement was apparent and no new mass movement features were noted above the Elk Creek mine. The <br />2004 inspection noted tension cracks in sandstone outcrops and two track ranch road. See the 2004 report <br />for details. <br />Please contact me at 970-929-5806 if you have any questions concerning the OMLLC annual subsidence <br />monitoring program. <br />Sincerely, <br />es A.
