EMD (Panels 2-Right through 6-Right, PR97-04) <br />• As with the EMD, the proposed operations will not impact areas of unusually high value for fish and wildlife. The <br />prior database survey, which is present in Exhibit 19A, indicates no nesting activity is occurring within the Middle , <br />Creek drainage. The tecovery rooms for the southern longwall panels in the EMD will be sufficiently removed <br />from the Twentymile Sandstone outcrop to prevent complete failure of4he face. Therefore, the nests located in this <br />section of the Twentymile'Sandstone will not be impacted liy the'continuing operations in the EMD. <br />• <br />NMD and WMD (Panels 17-Rigtit through 25-Right and 12-Left,through 17-Left, PR 03-06 and PR06-07)' <br />TCC's continued expansion into these azeas of the North and West Mining Districts, will not impact azeas of <br />unusually high value for fish and wildlife. There are no cliffs in the azea that will be subsided, so there is no <br />potential for subsidence impacts to raptors. The Fish Creek valley will be subsided, as shown on Map 23, resulting <br />in the potential for seasonal flooding of low-lying areas and an increase in groundwater levels, relative to the <br />subsided surface along the margins of drainages channels. Both of these subsidence effects have the potential to <br />increase riparian vegetation and habitat along the margins of affected drainages. The flooded azea will be dictated ' <br />by surface flows in Fish'Creek. During spring runoff, more of the valley will be flooded, with flows and water <br />levels declining as the runoff abates. Rough approximations of flooded azea acreages are presented in the AVF <br />report prepared by SubTerra for this revision. + <br />Protection of the hydroloeic balance. <br />• <br />• <br />PR06-07 2.05-127.1 11 /07/06 <br />
