EMD (Panels 2 -Right through 6 -Right, PR97-04) As with the initial EMD panels (9 -Right through 7 -Right), the proposed operations will not impact areas of unusually high value for fish and wildlife. The prior database survey, which is present in Exhibit 19A, indicates no nesting activity is occurring within the Middle Creek drainage. The recovery rooms for the southern longwall panels in the EMD will be sufficiently removed from the Twentymile Sandstone outcrop to prevent complete failure of the face. Therefore, the nests located in this section of the Twentymile Sandstone will not be impacted by the continuing operations in the EMD. NMD and WMD (Panels 17 -Right through 24 -Right, 12 -Left through 20 -Left, and 14- and 15 -Left Inby, PR 03-06, PR06-07, PR09-08, TR07-63, TR08-64, TR09-68, TR09-71) TC's continued expansion into these areas of the North and West Mining Districts, will not impact areas of unusually high value for fish and wildlife. There are no cliffs in the area that will be subsided, so there is no potential for subsidence impacts to raptors. The Fish Creek valley will be subsided, as shown on Map 23, resulting in the potential for seasonal flooding of low-lying areas and an increase in groundwater levels, relative to the subsided surface along the margins of drainages channels. Both of these subsidence effects have the potential to result in beneficial increases in riparian vegetation and habitat along the margins of affected drainages. The flooded area will be dictated by surface flows in Fish Creek. During spring runoff, more of the valley will be flooded, with flows and water levels declining, as the runoff abates. Rough approximations of flooded area acreages are presented in the AVF report prepared by SUbTerra for these revisions. Wolf Creek Reserve (Panels WC-5RT through 9RT, TR13-83, PR14-10, PR15-11) The planned development and mining of the Wolf Creek Reserve will not impact areas of unusually high value for fish and wildlife. There are no cliffs in the area that will be subsided, so there is no potential for subsidence impacts to raptors. The Fish Creek valley will be subsided, as shown on Map 23, resulting in the potential for seasonal flooding of low-lying areas and an increase in groundwater levels, relative to the subsided surface along the margins of drainages channels. Both of these subsidence effects have the potential to result in beneficial increases in riparian vegetation and habitat along the margins of affected drainages. The flooded area will be dictated by surface flows in Fish Creek. During spring runoff, more of the valley will be flooded, with flows and water levels declining, as the runoff abates. Roughm approxiations of flooded area acreages are presented in the AVF report prepared by SubTerra for these revisions. In those areas where ancillary facility installations such as ventilation installations, utility boreholes, and dewatering facilities are necessary to support mining and related activities, plans for surface disturbance and ongoing activities will be reviewed with Colorado Parks and Wildlife (CPW) to identify any potential wildlife impacts and incorporate any appropriate mitigation measures. In general, TC will incorporate any appropriate CPW mitigation recommendations in the proposed development, mining, and reclamation plans. Dependent on the specific location and circumstances, this may involve relocation of proposed roads and surface installations, seasonal or daily timing restrictions, measures to control activities and noise (ie: shielding, noise reduction measures, facility enclosures. limitations on site lighting or automatic sensors, fencing, etc.). 3 Protection of the hydrologic balance.
