-z7- The Division finds that, pursuant to Rule 2.07.6(2)(c), the proposed operation will minimize effects to the prevailing hydrologic balance outside the permit area. Reference Tremain, Carol M. 1983. Coal Bed Methane Potential of the Piceance Basin, Colorado. Colorado Geological Survey, Department of Natural Resources, Denver, Colorado 80203. Open - File Report 82-1. Climatolo ical Information and Air Resources -- Rules 2.04 8 2.05.4 2 h 2.05.6 1 and 4.17 The sections of the permit application dealing with climatologicl information and air resources have been reviewed by the Division. Climatological information is presented on page 59 of the application. The air pollution control plan and an initial Emissions Permit from the Colorado Department of Health are contained in Appendix B of the application. The initial permit allows for the crushing and screening of 200,000 tons of coal per year. The proposed operation is in compliance with the requirements of this section. XI. Topsoil -- Rules 2.04 9, 2.05.3(5), 2.05.4(2)(d) and 4.06 Soils resource information is presented on pages 59 through 60 of the application. Topsoil salvage is discussed on page 96A-D and topsoil redistribution is discussed on page IOTA. The soils along Harvey Gap are derived frdm the weathered Mesa Verde sandstones and shales. Colluvial and alluvial deposition has resulted in deep clayey to loamy soils along the tae slopes and valley bottom, with thin rocky soils occurring on the steep valley sideslopes. Previous mining disturbance (excavation, traffic and waste disposal) have altered the soils at the Eastside Mine site. However, the applicant has conducted soil sampling in areas to be redisturbed, and has identified areas where suitable soil occurs. Approximately 4 feet of soil material will be salvaged in the proposed waste disposal area, and approximately 2 feet will be salvaged in the proposed office area. These sites occupy valley bottom and toe slope topographic positions. The soils are primarily looms and clay, looms with pH between 7 and 7.8., E.C. below 6umhos/cm, and SAR values below 9, indicating suitable plant growth media.. Salvageable soil does not exist at the site of the portals or the proposed coal yard expansion area due to the severity of previous disturbance (in the case of the portals and mine yard) and the fact that pre-disturbance soils were shallow and rocky due to the original valley slope topographic position (coal storage expansion area).
