both seams will be mined, maximum subsidence do the tract is predicted to be :L0.22 feet. ~ • Bluffing at the outcrop could occur but geologic conditions of the coal viii not alloy mining close co the outcrop, therefore Bluffing is unlikely. Transportation There is no coal truck traffic increase expected as a result of this operation. At 4 million tons per year production, seven to eight trains per week would haul coal and at maximum production of 5.0 million tons per year, nine to ten trains per week would haul coal out of the valley from the West Elk !fine. At maximum production for all mines in the North Fork, [Lain traffic would increase co 14 trains per week. This is an increase of three trains per week from the number of trains per week hauling coal in 1993. County wide traffic associated with coal related growth would not be expected to significantly overload any county or Scace road system. While traffic accidents would be expected to increase an unspecified amount, the accident rate (accident per vehicle mile) itself would not be expected to increase. Wildlife and Endaneered Species Surface disturbances and activity associated with development and operation of above ground coal mining facilities would affect wildlife to the •extent they would destroy habitat, disrupt behavioral activities, causing increased competition on adjacent areas, cause direct mortality, or decreased natality. Existing stands of Grand Mesa penscemon, a candidate species, would be dist,arbed with initial disturbances. In the long term though, they could be increased since this species appears to be disturbance dependant. However, plant survey would be required prior to any surface disturbance co determine their presence. , Breeding and nesting habitat of the loggerhead shrike and other neott:opical birds would be diminished by disturbances in sagebrush, Gambel oak, and riparian vegetation stands. Disturbances in the sagebrush and oak stands should be avoided co the extent possible. No disturbances should occur. within the designated riparian areas. Bald eagle nest sites, winter roost sites, and winter concentration areas:, and Golden eagle nest sites which may be established during the life of this project would be affected co the degree disturbances would occur. Through consultation with the Service and Colorado Division of Wildlife protective measures have been developed co protect these sites. Water depletion associated with coal mining on this tract would impact populations of Colorado squavfish, Razorback sucker, Humpback chub, and - Bonyt:ail chub and their critical habitats found downstream in the Gunnison and Colorado Rivers. Even though there is no anticipated water use or ~-.~ 21
