_ .

Designed operational drainage control measures and postmining drainage reestablishment u-ill provide an increased level of mnoff and drainage control over prenuning conditions during the operational phase and will restore natural drainage conditions following completion of mining, so there should be no adverse impact on runoff or stream flows and no increase m the potential for flooding. 8) Geologic Hazards Increase of Existing Geolov,}tc_Hazatd or Subject Adjacent Properties to Geologic Hazards -Under SCC's approved Mining and Redamadon Pezmit (refer to Tabs 12, 13, and 20 of the CDMG PAP) all mining activities and constructed structures (i.e.: roads and sedimentation ponds) aze required to be designed to be stable under normal conditions of construction and operation. The approved Mining and Reclamation Plans also stipulate that the postmining reclaimed configuration should be established to assure long-term stability. There are some existing areas of natural instability within the Seneca IIW Mining Area, however, these are limited to shallow surgical slumps and do not represent major landslide features. SCC has vied to avoid disturbance of these areas where feasible or has undertaken appropriate engineering design and construction measures where avoidance is not feasible (i.e,: where it may be necessary for a road to cross a slump area). In many cases, surface mining operations eliminate existing surgical stability problems through excavation and subsequent backflL+ng, regarding, and reestablish_*nent of effective surface drainage. The proposed h-ghwall min-ng operations wi]I not affect surface stability since they will result in no_additional~urface_distusbance-and_pillazs-of-un-mined-coal-will-be-retained-to--prevent collapse and associated surface subsidence. 9) -None have been identified. 10) Truck Traffic To and From Such Uses Shall Not Create Hazards or Nuisance to Areas Elsewhere in the County Nor Sha11 it Unduly Damage Public Roads - (refer to Project Description/Narrative -Section 12, All Roads to be Used for Project, Existing Condition of Roads, and Anticipated Improvements; Petitioner Shall Report on the Following- Section 4, Noise Abatement Techniques; and Other Project Considerations -Item A, above) 11) That Such Use is Designed and Will be Developed in Manner to Allow Man to Function in Harmony With Wildlife Habitat - (refer to Reclamation Plan -Section 2, Proposed Future Land Use and It's Locations). The proposed highwall mining operations will occur within existing surface mined pit areas and will not result in any additional surface disturbance. By limiting the amount of surface dismrbance at any given time and through contemporaneous reclamation of mining disturbance areas, SCC has maintained a effective balance between land development and use and protection of the natural environment, including wildlife habitat. SCC is recognized as a leader in Northwest Colorado for effective restoration of wildlife habitat, with reclaimed mine areas providing prime habitat for elk, deer, and a variety of ocher wildlife species. is+RASm... <o,ACrnO!P^Vlix lM.../~]OJ)C SfLI'n..M+..i ro/z/m m.
