purpose, the North Fork alluvium. The Bowie No. 1 Mine, through an agreement with Pitkin Mesa Pipeline Company, obtained additional water for mine consumption. This water was also drawn from the Steven's Gulch alluvium, but under the pipeline company's water right. BRL proposes to replace the water supply of any legitimate water user if impacted by the mine until such time as repairs are instituted. The application includes specific sources of water owned by Bowie Resources LLC that will be called upon. A subsidence repair plan for springs, ponds, streams, and other resources is included in Subsidence Volume 3. Topsoils - Rules 2.04.9.2.05.3(5). 2.05.4(2)(d). 4.06 Information pertaining to soil resources and their inventory may be found on pages 67 to 69, Part 2.04 of Volume 1 and in the Soils Appendix of Volume 9. Information pertaining to topsoil handling and redistribution may be found on pages 50 to 53 and 63 to 67, Part 2.05 of Volume 1. Disturbance at the Bowie No. 1 Mine commenced in late 1975 but has presently ceased due to the cessation of mining. Laws pertaining to topsoil salvaging have become more stringent with the enactment of each additional law. The initial development work of the Bowie No. 1 East Mine benches and the storage and loadout areas occurred from October 1975 to mid-1976, prior to the enactment of the Colorado Mined Land Reclamation Act of 1976 and its topsoil salvaging requirements. Due to the steep slopes in these areas, no topsoil was salvaged. Since enactment of the 1976 law, topsoil has been salvaged from disturbed areas. Soils within those portions of the permit area which have been or will be disturbed by surface operations and facilities are generally deep, encouraging surface runoff. As a result, the water erosion hazard is often high. Generally, available water capacities are high, reflecting the potential of these soils to store water for plant use. Topsoil layers at the existing facilities are shallow, ranging from about two (2) inches to eight (8) inches; surface textures are generally loams or clay loams with subsoils ranging from clay loams to clays. However, at the Roatcap Creek facilities soils are much deeper, ranging from two (2) feet to four (4) feet in many places. Basaltic cobbles and stones are common throughout the profile of most soils. The general area is somewhat susceptible to landslides, especially in the steeper topography of the mine bench area and, as such, the continual sloughing of colluvial material in this area impairs horizon development. Vegetation Rules 2.04.10, 2.05.4(2)(e), 4.15 Information pertaining to vegetation baseline may be found on pages 70 to 75, Part 2.04 of Volume 1 and in the Vegetation Appendix of Volume 9A. Information pertaining to the revegetation plan and vegetation success criteria may be found on pages 67 to 76, Part 2.05 of Volume 1 and in the Vegetation Appendix of Volume 9A. Disturbance at the Bowie No. 1 Mine began in late 1975 but has presently ceased due to a permanent cessation of mining. Initial disturbance occurred prior to any requirements for preparation of vegetation inventories; therefore, portions of this mine site were not surveyed. However, as new areas were proposed to be disturbed, they were first inventoried. Nine vegetation types have been inventoried in the mine permit area, including agriculture, aspen, mixed shrub, mountain meadow, oakbrush, pinon juniper, sagebrush, sparse herbaceous understory, and riparian. The majority of the disturbed areas at Bowie No. 1 Mine are located in oakbrush communities dominated by Gambel oak ( uercus gambelii) and serviceberry (Amelanchier alnifolia) and in pinon juniper 17
