Newlin Creek Monument <br />Data collected for the Newlin Creek Monument are shown on Table <br />3, Subsidence Monitoring Data Summary. No mining has taken place <br />in the area of the monument for the period of record. <br />The data indicates that no additional subsidence is occurring at <br />the monument location. As stated in a previous semi-annual re- <br />port, most of the total subsidence to date occurred during the <br />period of May through September, 1985. It is anticipated that <br />only minor additional subsidence will occur at the monitoring <br />point. <br />Thompson Ranch Structures <br />All data for the period of record are presented on Table 3, Sub- <br />sidence Monitoring Data Summary. The data indicates that only <br />minor subsidence has occurred at the structure locations, and no <br />additional subsidence was measured for the period of record. It <br />is anticipated that only minor additional subsidence will contin- <br />ue to occur at these structures. <br />Conclusions <br />The zequired subsidence monitoring program continues to measure <br />the magnitude of subsidence on structures and within the high- <br />resolution grid area. The maximum subsidence values measured to <br />date are comparable to the predictions made in the mining permit. <br />No structural damage has been observed, or is expected to occur, <br />as a result of Southfield's mining operations. Further subsi- <br />dence occurring at the monitored structures and monuments is <br />expected to be minor and within maximum values predicted in the <br />mining permit. <br />or.: ::, <br />
