XIII. Protection of Fish Wildlife and Related Environmental Values <br />No specific approvals are granted under this section <br />XIV. Protection of Underground Mining <br />No specific approvals are granted under this section. <br />XV. Subsidence Control <br />A. The applicant previously proposed a subsidence control plan in accordance <br />with Rule 2.05.6(6) and had committed to adopt all measures in order to <br />reduce the likelihood of subsidence, prevent material damage, or mitigate <br />the effects. The Division previously approved the plan (4.20.1(2) and <br />4.20.3(1)). <br />B. The applicant conducted a subsidence monitoring program, in accordance <br />with Rule 2.05.6(6)(c), designed to determine the commencement and <br />magnitude of subsidence movements. The results of the monitoring <br />program were submitted to the Division semi-annually. The monitoring <br />program was designed to extend for a time, beyond cessation of mining in <br />any area, consistent with the need for verification of the subsidence <br />prediction. Technical Revision # 46 that was approved in October 1997 <br />terminated subsidence monitoring. <br />XVI. Concurrent Surface and Underground Mining <br />No specific approvals are granted under this section. <br />XVII. Operations on Alluvial Valley Floors <br />A. The Division has determined that an alluvial valley floor exists within the <br />affected or adjacent area. Therefore, the following findings are in order for <br />the alluvial valley floor known as the Picketwire Valley located along the <br />Purgatoire River. <br />The Division finds that activities proposed by the applicant will not <br />interrupt, discontinue, or preclude farming on the alluvial valley floors <br />that are irrigated or naturally subirrigated (4.24.3(1)). <br />2. The proposed activities will not materially damage the quantity, or <br />quality of water in the surface or ground water system described <br />above (4.24.3(3) and 2.06.8(5)(a)(ii)). <br />3. The operation produced coal in commercial quantities and was located <br />within or adjacent to an alluvial valley floor prior to August 3, 1977 <br />16
