Monitoring Wells - Active monitoring wells within the projected subsidence area(s) will be monitored on the <br />regular hydrologic monitoring schedule. If monitoring results, specifically water levels, indicate any significant <br />changes due to undermining or subsidence, TCC will conduct further testing and/or inspection to determine <br />whether or not the integrity of the well has been compromised. If the resulting information indicates that the <br />well has been damaged beyond repair, if appropriate, TCC will prepare and submit a revision to the permit for a <br />replacement well, and then will construct and initiate monitoring of the replacement well. <br />Subsidence reports will be submitted to the CDRMS semi - annually. The reports will be submitted 60 days after <br />the end of the period, unless TCC requests an extension of the submittal date. The planned reporting format is <br />shown in Exhibit 34, Subsidence Survey Report. <br />(d) (i) If a subsidence monitoring program determines, in the opinion of the Division <br />that the subsidence prediction was inaccurate and that the material damage or diminution of reasonable <br />foreseeable use of structures or renewable resource lands may occur, the permittee will be required to submit a <br />subsidence control plan, as defined in Section 2.5.6(6)(8. <br />(ii) In order to protect structures and renewable resource lands within the permit <br />and adiacent area the Division after consultation with the permittee shall suspend underground coal mining <br />under structures of renewable resource lands, if imminent danger of material subsidence damage or diminution <br />of reasonablv foreseeable use is determined to exist. <br />(e) A subsidence survey, pre arp ed by appropriately qualified professionals in accord with the <br />current state -of -the -art of subsidence prediction technology, shall contain the following information: <br />(i) A detailed description of subsidence predicted to occur within the permit and <br />adjacent area, including <br />(A) A brief description of the planned mining methods. <br />(B) A brief description of geologic properties which influence subsidence <br />occurrence, such as rock mechanics character of the affected materials geologic structure of the affected <br />materials, faulting and fracturing of the involved geologic section and permit and adjacent area topography' <br />(C) A brief description of local mining experience concerning subsidence <br />occurrence. if any: <br />PR09 -08 2.05 -191.8 04/29/09 <br />
