Subsidence Monitoring <br />~ Bear performed extensive subsidence monitoring at the Bear No. 3 Mine. This <br />monitoring is documented in Exhibit 22. In general, the elevation of the subsidence <br />monitoring stations has constantly decreased. BCC generally followed the <br />convention that subsidence monitoring could be discontinued two years after retreat <br />mining. Subsidence monitoring requirements for the last two years of mining (1995 <br />& 1996) was limited to visual monitoring as outlined on page 2.05-63e. <br />Slope Stability Monitoring <br />Bear performed extensive slope stability monitoring which was required by <br />Stipulation No. 21. This monitoring is documented in Exhibits 21 & 22. The last <br />monitoring performed was in 1996. The extensive slide activity that occurred in <br />June 1997 made further slope stability monitoring futile. <br />2.05 -iii 1/03 <br />/~ 2-as <br />(fin,-ov) <br />/~ PPR ov~,4 ! t~i v~o3 <br />
