road will be returned to existing contours when mining is completed and returned <br /> to its current use as rangeland <br /> 8. The pit is existing side hills in rangeland which will be mined by beginning at the <br /> western edge of the pit limits and excavating easterly. The pit floor will be graded <br /> to a relatively level hill top elevation, continuing until sufficient quantity of <br /> aggregate is removed to fulfill requirements for the project. <br /> 9. The slopes of the excavation will be made a 4H:1 V slope or flatter. The slopes <br /> will be graded as the excavation proceeds and vertical pit walls will not be <br /> necessary. <br /> 10. The dimensions will be as shown on Exhibit E —Mining Plan Map. The pit limits <br /> are rectangular in shape with leg lengths of approximately 1,815 feet long (N—S) <br /> and 718 feet wide (E—W) for an affected area of 29.3 acres within the excavated <br /> area. <br /> 11. There will be no depressions left after mining operations are completed and <br /> therefore no impoundments or drainage alterations will be left in the reclaimed <br /> area. <br /> 12. Water will be used within the pit will be for dust control only. The source of this <br /> water will be from the City of Flagler. Total usage will be approximately 2 acre- <br /> feet. <br /> 13. A storm water management plan will be filed with the Colorado Department of <br /> Health to maintain the hydrologic balance. <br /> 14. This excavation is into virgin ground. It is not anticipated that any foreign refuse <br /> or acid or toxic producing materials will be encountered. <br /> 15. Since the before and after use of the land is rangeland, minimal change will result <br /> to the hydrologic balance, no off-site damage will occur and the slopes and other <br /> general configuration of the land will be more stable for the current and reclaimed <br /> use due to elimination of existing erosion (caused by normal natural wind and <br /> water action over time) . No standing water will be retained longer than 24 hours. <br /> In addition, the excavated area will be mulched to eliminate topsoil erosion. <br /> 16. Excavation will be in the hill tops of the site and therefore will be kept above any <br /> possible ground water elevation. The operation will not require any type of <br /> dewatering. <br /> 17. This property is hilly with slopes crossing the proposed pit limits on the north, <br /> south and easterly sides of the mining area. It is the intent to excavate the property <br /> so as not to allow any runoff from excavated area. Adequate temporary berming <br /> (as shown on Exhibit E—Mining Plan Map), will be performed on the <br />
