2.05.6(6) <br />Prior to commencing mining activities on lease COC -75916 that could <br />cause subsidence, an appropriate augmentation plan for replacement <br />water will be decreed. The augmentation plan will consider drought <br />conditions and the limitations of local water supplies. <br />(f)(v) A narrative of the detailed description of measures to be taken to determine <br />the degree of material damage or diminution of value or foreseeable use of <br />the surface follows: <br />(f)(v)(A) The features which might be materially damaged by subsidence include the <br />water resources, roads and trails, power lines, transmission towers, and <br />landslides within the permit and adjacent area. The Operator's facilities may <br />be damaged by rockfall activity. The creeks, springs and ponds within the <br />area projected to be mined in current mine plan (ref. Map 14 -13) have been <br />extensively monitored. The water level and water quality of the groundwater <br />within the formation has also been monitored. The results of the monitoring <br />are presented in Volume 111, Exhibit 3. Map 6, Geologic Hazards, shows the <br />present location of existing landslides, debris flow, potentially unstable <br />slopes and rock fall hazards. <br />No pre- subsidence survey is proposed for the power line support towers <br />located along Terror Creek because they are located in a limited extraction <br />zone or outside of the projected angle of draw. A pre- subsidence survey has <br />been done for Bruce Park dams, see Volume X. The pre- subsidence survey <br />consists of a Geotechnical Data Report for the Bruce Park Dam and an <br />Addendum to that report both presented in Volume X. The geotechnical <br />reports present geologic mapping and subsurface geotechnical data for the <br />main dam and saddle dam. An additional pre- subsidence inspection of the <br />Bruce Park dams, Bruce Park Landslide and the surrounding area was <br />preformed by YEH and Associates, Inc. during 2007. Their report is <br />presented in Volume IIIA, Tab 22. <br />No pre- subsidence survey is proposed for the Jess Barrow Homestead <br />Cabin. Grand River Institute took new pictures to document the condition of <br />the cabin. (ref. GRI Project No. 2012 -109 20 November 2012) <br />PR-14 2.05-167- 03/14 <br />
