<br />Page 3. <br />7. Information required under Rule 2.05.6(6), Subsidence Survey, Subsidence <br />Monitoring, and Subsidence Control, was only partially submitted. All <br />structures require a brief description and require location on a map. Roads, <br />buildings, wells, pipelines, compressor stations, stock ponds, and any other <br />man-made structures are considered structures under this Rule. The <br />applicant must describe the worst possible consequences for each of the <br />structures and subsidence control plans and monitoring for each. At this <br />time, the subsidence control plan, monitoring, and mitigation for the gas wells <br />has been developed assuming Allen seam mining. Please refer to #10 below. <br />DRMS Response: Partially complete. The application is now complete with regard to a <br />subsidence control plan for the Allen and Apache seam. The application remains <br />incomplete with regard to the rest of the original question. <br />NECC Response: The subsidence section pages 2.05-90g-94 have been modified to <br />describe the worst possible consequences for each of the structures. The subsidence <br />plan, Exhibit 24, has been revised to include subsidence control plans and <br />monitoring for each type of structure as described in Map 20 sheets 1-3. <br />Sincerely, <br />??'
