• J.E. Stover & Associates, Inc <br />September 3, 2007 <br />Page 3 <br />Habitat within the mine permit boundary was evaluated during an August 11, 2007 site visit. Habitat <br />descriptions and occurrence determinations outlined in Table 1 are based on professional <br />experience, personal communication with exerts, and published resources, including Colorado <br />Breeding Bird Atlas,4 Mammals of Colorado, CDOW habitat maps s U.S. Forest Service (USES) <br />habitat maps,' Colorado Herpetofaunal Atlas,e Amphibians and Reptiles in Colorado,a and the <br />Colorado Rare Plant Field Guide.l ° <br />Physical and Ecological Setting <br />The Blue Ribbon Mine is an inactive underground coal mine approximately 6.5 miles northeast of <br />the Town of Paonia, in Delta County, Colorado (Figure 1). The mine's permit boundary <br />encompasses 340.8 acres within Section 35, Township13 South, Range 91 West of the 6t" Principle <br />Meridian, and includes a total of 34 acres where surface disturbance is permitted (Figure 2). Within <br />the permitted area of surface disturbance, 16.9 acres were disturbed by Blue Ribbon mining <br />operations. Approximately 170.8 surface acres within the mine boundary are privately owned and <br />170 surface acres are public lands administered by the USES (Figure 1). National Forest lands <br />bound the mine permit area on the north, and U.S. Bureau of Land Management lands bound the <br />mine permit area on the south. The areas of permitted surface disturbance lie on privately owned <br />lands. <br />The mine boundary encompasses a 0.6-mile reach of Hubbard Creek and the flanks of the steeply <br />sloping foothills rising to the east and west. Forest Road 407 (open to the public) traverses the mine <br />permit area roughly parallel to and west of Hubbard Creek (Figure 2). The creek's narrow floodway <br />and historic floodplain are composed of undifferentiated Holocene and Pleistocene surficial <br />deposits." The steep slopes within the mine permit boundary are in the upper Cretaceous <br />Mesaverde formation (coal-bearing sandstone, siltstone, and shale). The lowest elevation within the <br />mine permit boundary is approximately 6,300 feet above mean sea level at Hubbard Creek. The <br />highest elevation is 7,880 feet on a knob in the east portion of the mine permit area. The mine's <br />surface disturbance (reclaimed) and above-ground activities occurred at elevations below 6,600 <br />feet in the historic floodplain of Hubbard Creek and at the base of the steep hills to the east (Figure <br />2). Two small sediment ponds related to the operations of Blue Ribbon Mine remain in the locations <br />shown on Figure 2. The total estimated evaporative loss from the ponds is 0.57 acre-feet per year, <br />representing a loss of surface waters from the upper Colorado River basin. Other surface <br />disturbances within the Blue Ribbon permit boundary (and visible on Figure 2) are related to the <br />ventilation and methane drainage operations of the Elk Creek Mine, operating DRMS permit C- <br />1981-022. <br />° Kingery, H.E.
