10. The pit is an existing fairly flat rangeland. A maximum of 10 feet depth will be <br /> mined by beginning at the southeast edge of the pit limits and excavating North. <br /> The pit floor will be graded to a relatively level elevation for approximately 300 <br /> feet and then a max 4:1 slope will be built on the Easterly and Southern side of <br /> the pit. <br /> 11. The slopes of the excavation will be made a maximum of 4H:1 V slope or flatter. <br /> The slopes will be graded as the excavation proceeds and vertical pit walls will <br /> not be necessary. <br /> 12. The Pit Boundary dimensions will be as shown on Exhibit E—Mining Plan Map. <br /> The pit limits are irregular, the Westerly pit boundary line is 1,000 feet,Northerly <br /> pit boundary line is 708 feet, Easterly pit boundary line is 755 feet and the <br /> Southerly line is 634 feet. The actual area to be mined is 480 feet by 740 feet, <br /> this leaves approximately 60 feet buffer zone from the pit boundary to the <br /> area that is to be mined that will be used for stockpiling topsoil and truck <br /> haul roads. <br /> 13. 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 1 acre- <br /> foot. We have a lease in with the Town of Flagler for purchasing water. <br /> 14. A storm water management plan will be filed with the Colorado Department of <br /> Health to maintain the hydrologic balance. <br /> 15. This excavation is into virgin ground. It is not anticipated that any foreign <br /> materials will be encountered. If some were encountered, they would be disposed <br /> of in a manner to prevent unsightliness and protect the drainage system from <br /> pollution, as determined for the specific material. <br /> 16. 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) in the stable, steeper than 4:1 slopes. No standing water <br /> will be retained longer than 24 hours. In addition, the excavated area will be <br /> mulched to eliminate topsoil erosion. <br /> 17. Excavation will be kept above the known ground water elevation since the mining <br /> will be done out of the side of a hill therefore the operation will not require any <br /> type of dewatering. <br /> 18. Since we are mining to an elevation of 5,120, included in this package is a well <br /> permit about 1 mile away from this pit showing they found water at a depth of 90 <br /> feet. The elevation at the top of the well is at 5,120 going down the 90 feet puts <br /> us 90 feet above the water at 5,030. <br />
