2. General Mining Plan <br />General Items - Expansion Area Mining <br />The expansion area will be mined in phases which have been outlined in order to best mitigate <br />visual impacts from all viewpoints in the proximity of the mine, which was the primary design <br />criteria for the expansion area. It is not possible to mine without ever being visible; however a <br />great amount of effort has been put into ensuring that the mining visibility is minimized to the <br />northeast, east and southeast. This was the desire of the landowners as well as Pitkin County. All <br />of the mine designs are based on having the same annual production as was experienced in 2003; <br />which was approximately 235,000 tons. Future production may vary slightly depending upon the <br />market conditions. A breakdown of the materials which will be processed on site can be seen <br />below in Table 1. Map C-3 shows cross-sections through the expansion area and the existing pit <br />mined to its extents. The cross-sections show the current topography, the material which will be <br />removed from mining during each year and the final reclaimed topography. <br />'r..L I- 4 <br />¦ MM.Y <br />Average Annual Product Distribution <br />Product Tons Sold <br />Asphalt 82,077 <br />Road Base 72,021 <br />Pit Run 6,439 <br />Boulders 1,065 <br />Screened Rock/Sand 68,339 <br />Crusher Fines 2,048 <br />Natural Fines 13,404 <br />Total 235,393 <br />It is seen from the cross sections of Map C-3 that the gravel reserve in the expansion area will be <br />mined in slices that tilt downward toward the existing pit. It is expected that mining of the <br />expansion area will require 16 years, although this is dependent upon local demand. Map C-4 <br />shows the conditions at the end of the projected Year 7 of the expansion area mining. Map C-5 <br />shows the mining at the end of year 15. The expansion area will be mined to a 3H:1 V slope, <br />therefore, the current steep slope which exists on the east side of the pit will be eliminated by the <br />new mining.
