XV. Subsidence Control <br /> Section 2.05.6(6)of the permit contains an inventory of structures and renewable resource lands <br /> within the permit area,and a discussion of the possible consequences of subsidence on those <br /> structures and lands. A subsidence monitoring plan is also included in this section. A report <br /> containing subsidence predictions, impacts and possible mitigation measures may be found in <br /> exhibit 15 of the permit. <br /> A. The applicant has proposed a subsidence control and monitoring plan in accordance with <br /> Rule 2.05.6(6)and has committed to adopt all measures discussed in the plan,in order to <br /> reduce the likelihood of subsidence,prevent material damage,or mitigate the effects. <br /> The Division approved the plan(420.1(2)and 420.3(1)). With the approval ofTR-116, <br /> the requirement for subsidence monitoring was terminated. <br /> Because of the concerns about allowing mining within 1 mile of the Terror Creek <br /> Reservoir(Bruce Park dam), Stipulation No. 9 was added to the permit application to <br /> address concerns about subsidence and seismicity effects on the dam. <br /> XVI. Concurrent Surface and Underground Mining <br /> This section does not apply to the Bowie No. 2 Mine permit application. <br /> XVIL Operations on Alluvial Valley Floors <br /> A. The Division has determined that an alluvial valley floor does not exist within the <br /> affected area; however,an alluvial valley floor does exist in the adjacent area. Therefore, <br /> the following findings are made for the alluvial valley floor located along the North Fork <br /> of the Gunnison River,downgradient from the Bowie No.2 Mine. <br /> i. The Division finds that activities proposed by the applicant will not interrupt, <br /> discontinue, or preclude farming on the alluvial valley floors that are irrigated or <br /> naturally subirrigated (424.3(1)). <br /> ii. The proposed activities will not materially damage the quantity or quality of water <br /> in the surface or ground water systems described above (424.3(3) and <br /> 2.06.8(5)(a)(11). <br /> iii. The proposed activities will comply with the requirements of the Act and the <br /> Regulations,with respect to alluvial valley floors(2.06.8(5)(a)(111)). <br /> iv. Surface coal mining and reclamation operations will be conducted to preserve the <br /> essential hydrologic functions of alluvial valley floors outside the permit area <br /> throughout the mining and reclamation process(4242). <br /> B. An environmental monitoring system shall be installed,maintained,and operated by the <br /> permittee to ensure the protection of all alluvial valley floors during surface coal mining <br /> and reclamation operations and continued until all bonds are released in accordance with <br /> Rule 4.24.4. <br /> 24 <br />
