The dewatering borehole site was developed under an NOI and will be reclaimed during the summer of 1996. The <br />success standard for the NOI will be utilized in evaluating revegetation success for the site. The dewatering <br />borehole site consists of a borehole and pump control building, which encompass an azea of less than 0.2 acres. <br />• Both are of limited areal extent and do not require the creation of a reference azea to be evalauate revegetaation <br />success. The baseline data for the ventilation site is presented on Table 27A, EMD Baseline Vegetation Data, <br />Ventilation Site, and Table 27B, EMD Baseline Vegetation.Data, Dewatering Borehole Site. <br />Three surface disturbance sites within the EMD were surveyCd dtuittg May, 1995 relative to the requirements of <br />Rule 4.05.6 (2) (iii), Rare and Endangered Plants. ' A systematic approach wasi used in a complete seazch of <br />those aeeas for ~iranthes diluvialis, Ute Lady's Tresses, which grows in riparian habitats. In addition, the <br />survey included anomalous habitats. - , <br />The EMD Dewatering Borehole is located is on a hill where elevation ranges from 6,700 feet to 6,776 feet. <br />Vegetation is predominantly Artemesia arbuscula, low sage;, with some areas of Artemesia tridentata, Wyoming <br />big sage and their associated vegetation. This area has no perennial wetlands and no occurrences of the target <br />species were identified. <br />The dewatering borehole treatment ponds have been relocated to a location closer to County Road 33. The new <br />location is on a gentle slope that has been planted to Bromus inermis, smooth brome. This area has no perennial <br />wetland and no occurrences of the target species were identified in the parcel. <br />The other azea is where the EMD Ventilation Borehole is to be located. This is also on a hill south of Foidel <br />Creek. The elevation ranges from 6,750 to 6,850 feet. This area has been improved for hay production and <br />grazing. The dominant vegetation is Bromus inemus, smooth brome. There is no riparian habitat, and no plants <br />were located. <br />EMD (Pane12-Right through 6-Right, PR97-04) <br />• No new surface facilities are anticipated to support mining of coal' from the NMD. <br />NORTH MINING DISTRICT <br />NMD (Panels 12-Right through 16-Right, PR99-OS) <br />Except for the NMD power borehole and associated access road, no new surface facilities are contemplated in <br />pemut revision number 5. Also, as part of PR99-O5, a section of Fish Creek and its Alluvial Valley Floor will be <br />subsided and subsequently flooded. TCC conducted an Internet seazch to determine impacts to rare and <br />endangered plant species. Previously, Mr. Terry Ireland of the Grand Junction Office of the USFWS was <br />contacted to provide a listing of T & E species which could be present in Township SN, Range 86W, 6`" P.M. The <br />results of the inquiry indicate that Spiranthes diluvialis (Ute Lady' Tresses} is the only plant found within the azea <br />that could be potentially impacted. Amore recent (October 2006) check of the USFWS Endangered Species List <br />for Routt County indicates that Ute Lady' Tresses has been eliminated from the Routt County list. <br />Ute Lady's Tresses occw in habitats at an elevation of 6,500 feet or less. The distwbance associated with the <br />subsidence of Fish Creek and its AVF is located above an elevation of 6,500 feet. Therefore, TCC does not <br />anticipate any impact to any Threatened or Endangered plant species. <br />NW Mains Ventilation Shaft and Thickener Underflow Project (TROT-39) <br />The proposed NW Mains ventilation shaft site is at an elevation of approximately 6,700 feet. The dominant <br />vegetation community in this area is pastwe/meadow with a mixture of grasses including brome, timothy, <br />• bluegrass, and wheatgrass and some sagebrush. The associated access road and powerline corridors include <br />both upland areas and a lowland area where the road and powerline cross Fish Creek. Jn the lowland areas, the <br />meadow vegetation type includes various grasses, rushes, and sedges. Based on a wetland delineation <br />conducted by Habitat Management, Inc., the proposed development activities will distwb approximately 0.29 <br />PR06-07 2.04-61 11/07/06 <br />
