addition, Sunland Mining has committed to three measures in order to minimize impacts to wildlife resources: 1. Limiting activity during the sensitive deer and elk wintering period; 2. Prohibiting the use of persistent pesticides; and 3. Prohibiting the dischazge of firearms by employees. No electric transmission lines exist or are proposed to be constructed which pose a threat to raptors.l (4.18(4)(g)). XIV. Protection of Underground Mining The Apex No. 2 Mine operated adjacent to the abandoned Apex No.l mine and utilized the Apex No.l portal for ventilation. This practice was started prior to the implementation of these regulations (4,19(1) and 4.22.4(1)). XV. Subsidence Control Sunland Mining Corp. hired a consulting firm to develop a subsidence control plan for the mine. The only resource identified in the permit area requiring protection is a seasonally occupied ranch house located in Fault Block No. 3. Sunland Mining Corp. had committed in the original permit application to subsidence monitoring and a reduction in coal recovery in this fault block as measures to protect this ranch house. As part of Permit Renewal No. 1 application, Sunland Mining Corp. has dropped consideration of mining in this fault block. Based on hydrologic investigations and the nature of the geology, the Division has concluded that any subsidence above the planned mined area will have negligible, if any, impact on the ground water regime. Information pertaining to subsidence is presented on pages 189-190 and 194-211. XVI. Concurrent Surface and Underground Mining At the Apex No. 2 mine, mining was not conducted concurrently with surface mining, therefore, specific findings for this section are not required (4.22.2). XVII. Operations on Alluvial Valley Floors (AVF) From the information submitted, the Division has determined that Trout Creek and Middle Creek meet the criteria of an AVF. The Trout Creek AVF runs through the Apex No. 2 Mine, C-81-011 19 May S, 1993
