• CHAPTER ZV ENVIRONMENTAL CONSEQUENCES OF THE ALTERNATIVES A. Critical Resources 1. Cultural Resources The State Historic Preservation Officer noted in a letter dated December 13, 1993, that there are no known cultural resources within the project area. This mining plan modification area will not experience any new direct surface disturbance. New cultural resource finds will be protected by a special condition to the mining plan approval. 2. Water Supply and Quality Values The small size of the Bear underground workings and the surface facilities will limit the extent of mining impacts on the hydrologic system. The three seasonal springs in the vicinity of the Bear Mine permit area are primarily associated with sandstones in the Barren member of the Mesaverde formation, which will not be affected by subsidence fractures. No important depletion of ground water in the B seam is • expected to result from mining. The small inflows that have occurred in the past and the lack of any recorded mine discharges indicates that no impacts to ground water resources will result from mining in the B seam. Surface water resources are not expected to be affected by the proposed mining plan modification. 3. Wetland values There are no areas containing wetland values in the mining plan modification area. 4. Floodplains, Areas of Unstable Geology, and Natural Hazards There are no areas subject to frequent flooding in the mining plan modification area. There are no slide bodies of concern in the mining plan modification area. No subsidence effects are expected to occur in the critical toe area of any of the slide bodies. Subsidence in these areas will be controlled by split pillar removal. 5. Threatened or Endangered Species ri u 13
