springs, ponds, streams, and other resources is included in Subsidence Volume 3. These repair <br />plans will be modified and refined depending on future experience with subsidence. The first <br />five-year mine plan azea was located in areas that did not contain many significant water <br />resources. This allowed Bowie Resources Limited to obtain subsidence and repair experience <br />prior to mining sensitive areas. <br />The State Engineer's office was consulted during the course of the initial application review. <br />However, no approval of the mitigation plan could be granted by the SEO since the SEO is not <br />authorized by law to approve augmentation plans. <br />Toasoils -Rules 2.04.9, 2.05.3(S), 2.05.4(2)(d), 4.06 <br />Information pertaining to soil resources and their inventory may be found on pages 67 to 69, Part <br />2.04 of Volume I and in the Soils Appendix of Volume 9. Information pertaining to topsoil <br />handling and redistribution may be found on pages SO to S3 and 63 to 67, Part 2.OS of Volume 1. <br />Disturbance at the Bowie No. 1 Mine commenced in late 1975 but has presently ceased due to <br />the cessation of mining. Laws pertaining to topsoil salvaging have become more stringent with <br />the enactment of each additional law. The initial development work of the Bowie No. 1 East <br />Mine benches and the storage and loadout azeas occurred from October 1975 to mid-1976, prior <br />to the enactment of the Colorado Mined Land Reclamation Act of ] 976 and its topsoil salvaging <br />requirements. Due to the steep slopes in these areas, no topsoil was salvaged. Since enactment <br />of the 19761aw, topsoil has been salvaged from disturbed areas. <br />Soils within those portions of the permit azea which have been or will be disturbed by surface <br />operations and facilities are generally deep, encouraging surface runoff. As a result, the water <br />erosion hazard is ofren high. Generally, available water capacities are high, reflecting the <br />potential of these soils to store water for plant use. Topsoil layers at the existing facilities aze <br />shallow, ranging from about two (2) inches to eight (8) inches; surface textures are generally <br />foams or clay foams with subsoils ranging from clay foams to clays. However, at the Roatcap <br />Creek facilities soils aze much deeper, ranging from two (2) feet to four (4) feet in many places. <br />Basaltic cobbles and stones are common throughout the profile of most soils. The general area is <br />somewhat susceptible to landslides, especially in the steeper topography of the mine bench area <br />and, as such, the continual sloughing of colluvial material in this area impairs horizon <br />development. <br />Vegetation Rules 2.04.10, 2.05.4(2)(el, 4.15 <br />Information pertaining to vegetation baseline may be found on pages 70 to 75, Part 2.04 of <br />Volume 1 and in the Vegetation Appendix of Volume 9A. Information pertaining to the <br />revegetation plan and vegetation success criteria may be found on pages 67 to 76, Part 2.OS of <br />Volume 1 and in the Vegetation Appendix of Volume 9A. <br />Disturbance at the Bowie No. 1 Mine began in late 1975 but has presently ceased due to a <br />temporary cessation of mining.
