<br />-6- <br />Description of the Environment <br />The Orchard Valley Mine is situated in the northeastern portion of Delta <br />County, Colorado and is located approximately 4 miles north of Paonia, <br />Colorado along the Steven's Gulch Road. The western extremities of the <br />Orchard Valley Mine permit area are bounded closely by the East and West <br />Roatcap Creek drainage divide, and the northern boundary is located at <br />approximately the Morrell Cow Camp area. The location of the entire Orchard <br />Valley Permit area can be found on Figure 1. The coal loadout facilities are <br />located approximately 1 mile northeast of Paonia along State Highway No. 133. <br />The general area in which the mine is located is characterized by a semi-arid <br />environment of steeply sloping mountains. <br />Both the mine portal facilities and the loadout were constructed in the 1970's <br />prior to the passage of SMCRA or the Colorado Surface Coal Mining and <br />Reclamation Act. <br />Soils within those portions of the permit area which have been or will be <br />disturbed by surface operations and facilities are generally deep, <br />well-drained, and vary widely in slope. Permeability values are low, thus <br />encouraging surface runoff. As a result, the water erosion hazard is often <br />high. Generally, available water capacities are high, reflecting the <br />potential of these soils to store water for plant use. Topsoil layers are <br />shallow, ranging from about 2 inches to 8 inches, surface textures are <br />generally loams or clay loams with subsoils ranging from clay loams to clays. <br />Basaltic cobbles and stones are common throughout the profiles of most soils. <br />The general area is somewhat susceptible to landslides, especially in the <br />steeper topography of the mine bench area, and as such, the continual <br />sloughing of colluvial material in this area impairs horizon development. <br />The general area contains important winter range for both elk and deer, and <br />over 10,000 hunter days per year are spent in this area. Golden eagles have <br />been noted near the mine site, but no threatened or endangered wildlife <br />species have been observed. The North Fork of the Gunnison River contains 12 <br />species of fish, including 3 species of game fish (rainbow trout, brown trout, <br />and northern pike). However, due to the poor production of benthic organisms <br />and poor habitat conditions, the North Fork is not stocked frequently. <br />The permit area can be divided into two general land use categories. The <br />loadout is within an area historically used as cropland, or more specifically, <br />orchard land. The permit area north of Highway 133 is used as short term <br />grazing and wildlife habitat. Grazing tends to be short term due to the low <br />productivity of the pinyon-juniper andd oakbrush vegetation. <br />Some recreational use, hunting and hiking in particular, occurs wihtin the <br />mine area. There are also a few summer homes, cow camps, and even a <br />restaurant that has been used intermittently. <br />
