The dewatering borehole site was developed under an NOI and will be reclaimed during the summer of 1996. The success standard for the NOI will be utilized in evaluating revegetation success for the site. The dewatering borehole site consists of a borehole and pump control building, which encompass an area of less than 0.2 acres. • Both are of limited areal extent and do not require the creation of a reference area to be evalauate revegetaation success. The baseline data for the ventilation site is presented on Table 27A, EMD Baseline Vegetation Data, Ventilation Site, and Table 27B, EMD Baseline Vegetation.Data, Dewatering Borehole Site. Three surface disturbance sites within the EMD were surveyed during May, 1995 relative to the requirements of Rule 4.05.6 (2) (iii), Rare and Endangered Plants. A systematic approach was! used in a complete search of those areas for Sniranthes diluvialis, Ute Lady's Tresses, which grows in riparian habitats. In addition, the survey included anomalous habitats. The EMD Dewatering Borehole is located is on a hill where elevation ranges from 6,700 feet to 6,776 feet. Vegetation is predominantly Artemesia arbuscula, low sage, with some areas of Artemesia tridentata, Wyoming big sage and their associated vegetation. This area has no perennial wetlands and no occurrences of the target species were identified. The dewatering borehole treatment ponds have been relocated to a location closer to County Road 33. The new location is on a gentle slope that has been planted to Bromus inermis, smooth brome. This area has no perennial wetland and no occurrences of the target species were identified in the parcel. The other area is where the EMD Ventilation Borehole is to be located. This is also on a hill south of Foidel Creek. The elevation ranges from 6,750 to 6,850 feet. This area has been improved for hay production and grazing. The dominant vegetation is Bromus inermis, smooth brome. There is no riparian habitat, and no plants were located. EMD (Panel 2 -Right through 6 -Right, PR97-04) • No new surface facilities are anticipated to support mining of coalfrom the NMD. NORTH MINING DISTRICT NMD (Panels 12 -Right through 16 -Right, PR99-05) Except for the NMD power borehole and associated access road, no new surface facilities are contemplated in permit revision number 5. Also, as part of PR99-05, a section of Fish Creek and its Alluvial Valley Floor will be subsided and subsequently flooded. TCC conducted an Internet search to determine impacts to rare and endangered plant species. Previously, Mr. Terry Ireland of the Grand Junction Office of the USFWS was contacted to provide a listing of T & E species which could be present in Township 5N, Range 86W, 6`' P.M. The results of the inquiry indicate that Spiranthes diluvialis (Ute Lady' Tresses) is the only plant found within the area that could be potentially impacted. A more recent (October 2006) check of the USFWS Endangered Species List for Routt County indicates that Ute Lady' Tresses has been eliminated from the Routt County list. Ute Lady's Tresses occur in habitats at an elevation of 6,500 feet or less. The disturbance associated with the subsidence of Fish Creek and its AVF is located above an elevation of 6,500 feet. Therefore, TCC does not anticipate any impact to any Threatened or Endangered plant species. NW Mains Ventilation Shaft and Thickener Underflow Project (TR01-39) The proposed NW Mains ventilation shaft site is at an elevation of approximately 6,700 feet. The dominant vegetation community in this area is pasture/meadow with a mixture of grasses including brome, timothy, •bluegrass, and wheatgrass and some sagebrush. The associated access road and powerline corridors include both upland areas and a lowland area where the road and powerline cross Fish Creek. In the lowland areas, the meadow vegetation type includes various grasses, rushes, and sedges. Based on a wetland delineation conducted by Habitat Management, Inc., the proposed development activities will disturb approximately 0.29 PR06-07 2.04-61 11/07/06
