After mining is completed for these operations all portals will be sealed and disturbances will be backfilled, graded, topsoiled and revegetated. In this reclaimed situation the hydrologic characteristics of the disturbed areas will be restored to nearly pre-mining conditions. The assessment of the probable cumulative impacts of all anticipated coal mining in the general area on the hydrologic balance, as described in 2.05.6(3), has been made by the Division, and the operations proposed under the application have been designed to prevent damage to the hydrologic balance outside the proposed permit area. cal Information and Air Resources - Rules 2.04.8 o nr c , ..,a n 1T ~,LI~III, •VJ~VI~II, VIIV T. 1/ The appropriate information dealing with climatology and air resources at the site is contained in Sections 4.6 and 4.7 of the permit application. Salt Creek Mining Company has included the required climatological information for Grand Junction. No site specific information is available. Salt Creek Mining Company has applied with the Colorado Department of Health for an emissions permit to cover all aspects of the operation. The operation is in compliance with the requirements of this section. XI. Soils - Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d), and 4.06 Information dealing with soils resources and topsoil handling procedures can be located in Sections 3.2, 3.3, and 4.4 of Volume I of the permit application. These Sections provide the basis for the following analysis. No topsoil was stripped prior to the existing disturbance at the McClave Canyon Mine as the operation existed prior to the enactment of SMCRA. However, topsoil was salvaged from the area of the sediment pond as this structure was constructed after the enactment of SMCRA. Soil material salvaged from the pond area was stockpiled adjacent to the pond on a stable area. The soils map provided by the applicant (Figure 4.4-1 - Soils Map Showing Depth Assessment) shows site specific mapping of soils information at an Order I or II Level of intensity. This map, in conjunction with the Surface Water Control Systems map (Figure 2.2-3), indicates that the disturbance created by construction of the sediment pond has affected the Nihill Loam and Rivra Gravelly Sandy Loam Variant soils. These soils were sampled in the vicinity of the proposed sediment pond disturbance and were analyzed by horizon to 70 + inches depth. -20-
