(i.e. improved by planting of smooth bromes) and comprises the larger of the two sites. The dewatering borehole <br />site was done under NOl and will be reclaimed during the summer of 1996. The success standard for [he NOI will <br />• be utilized in determining successful revegetation of the site. The dewatering borehole site will consist of a <br />borehole and pump control building, which will encompass an area of less than 0.2 acres. The baseline data for the <br />ventilation site is presented on Table 27A, EMD Baseline Vegetation Data, Ventilation Site, and Table 27B, EMD <br />Baseline Vegetation Data, Dewatering Borehole Site. Both are of limited areal extent and do not require the <br />creation of a reference area to be utilized in determining successful reclamation of the sites. <br />Three sites within the Eastern Mining District where surface disturbance is to occur were surveyed with regard to <br />Rule 4.05.6 (2) (iii), Rare and Endangered Plants. A systematic approach was used in a complete search of those <br />areas. The plant that was searched for, Spiranthes diluvialis, Ute Lady's Tresses, grows in riparian habitat, <br />however the survey included anomalous habitats as well. The survey was conducted during May, 1995. <br />The area where the Eastern Mining DisVict Dewatering Borehole will be located is on a hill. Elevation ranges from <br />6700 feet to 6776 feet. Vegetation is predominantly Artemesia arbuscula, low sage with some areas of Artemesia <br />tridentate, Wyoming big sage and their associated vegetation. This area has no perennial wetlands and no plants <br />were located. The dewatering borehole treatment ponds have been relocated to a location closer to County Road 33. <br />The new location is on a gentle slope that has been planted to Bromus inermis, smooth brome. This area has no <br />perennial wetland and no plants are located in the parcel. <br />The other area is where the Eastern Mining District Ventilation Borehole is to be located. This is also on a hill <br />south of Foidel Creek. The elevation ranges from 6,750 feet to 6,850 feet. This area has been improved for hay <br />production and grazing. The dominant vegetation is Bromus inermis, smooth brome. There is no riparian habitat, <br />and no plants were located. <br />EMD (Paoe12 Right through 6 Right)(PR 97-04) <br />• No new surface facilities are anticipated to support mining of coal from the NMD. <br />NMD (Panels 12 Right through 16 Right) (PR 99-OS) <br />Except for the NMD power borehole and associated access road, no new surface facilities are contemplated in <br />permit revision number 5. Also, as part of permit revision 5, a section of Fish Creek and its alluvial valley floor <br />will be subsided and subsequently flooded. TCC conducted an Internet search to determine impacts to rare and <br />endangered plant species. Previously, Mr. Terry Ireland of the Grand Junction Oftice of the USFWS was contacted <br />to provide a listing of T & E species which could be present in Township SN, Range 86W, 6'~ P.M. The results of <br />the inquiry indicate that Spiranthes diluvialis (Ute Lady' Tresses) is the only plant found within the area that could <br />be potentially impacted if certain criteria are met. <br />The Ute Lady's Tresses occurs in habitats at an elevation of 6,500' or less. The disturbance associated with the <br />subsidence of Fish Creek and its AVF is located above an elevation of 6,500'. Therefore, TCC does not anticipate <br />any impact to any threatened or endangered plant species. <br />NW Mains Ventilation Shaft and Thickener Underflow Project (TR O1-39) <br />The proposed N W Mains ventilation shaft site is at an elevation of approximately 6,700'. The dominant vegetation <br />community in this area is pasture/meadow with a mixture of grasses including brome, timothy, bluegrass, and <br />wheatgrass and some sagebrush. The associated access road and powerline corzidors include both upland areas and <br />a lowland area where the road and powerline cross Fish Creek. In the lowland areas, the meadow vegetation type <br />includes various grasses, rushes, and sedges. Based on a wetland delineation conducted by Habitat Management, <br />Inc., the proposed development activities will disturb approximately 0.29 acres of open water in the Fish Creek <br />. channel and approximately 0.10 acres of riverine wet meadow and emergent marsh for a total wetland disturbance <br />TR O1-39 2.04-61 8/10/01 <br />
