r <br />-5- <br />DESCRIPTION OF THE ENVIRONMENT <br />The Orchard Y alley Mine 1s situated in the northeastern portion of Oelta <br />County, Colorado and is located approximately four (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 Nest <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 Fiqure 1. The coal loadout facilities are <br />located approximately 1 mite northeast of Paonla along State Highway No. 133. <br />The general area 1n which the mine is located is characterized by a semi-arid <br />environment of steeply sloping mountains. <br />Both the main mine portal facilities and the loadout were constructed in the <br />1970's 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 1n slope. Permeability values are low, thus <br />• encouraging surface runoff. Asa 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 at the <br />existing facilities are shallow, ranging from about two (2) inches to eight <br />(B) inches, surface textures are generally looms or clay looms with subsoils <br />ranging from clay looms to clays. However, at the Roatcap Creek facilities <br />soils are much deeper, ranging from 2-4 feet in many places. Basaltic cobbles <br />and stones are common throughout the profile of most soils. fie general area <br />is somewhat susceptible to landslides, especially 1n the steeper topography of <br />the mine bench area, and as such, the continual sloughing of colluvial <br />material in this area impairs horizon development. <br />The general area contains lmportartt 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, Dut no threatened or endangered wildlife <br />species have been observed. The North Fork of the Gunnison River contains <br />twelve (12) species of fish, Including three (3) species of game fish (rainbow <br />trout, brown trout, and northern pike). However, due to the poor production <br />of benthic organisms and poor habitat conditions, the North Fork is not <br />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 and oakbrush vegetation. <br />
