facilities are shown on Exhibit C. Palletized stone will be stored within the permit area, <br />near the eastern and northeastern boundaries. <br />Landscape boulders were sorted and placed separately by the owner (TRAA) into <br />stockpiles shown Exhibit C. It is anticipated that all landscape boulders will be removed <br />over time and will not be part of the unsuitable material stockpile. <br />Projected annual processing totals are 5,000 tons for architectural stone and 1,000 tons of <br />landscape boulders. The stockpile quantity is estimated to be approximately 50,000 tons <br />of architectural stone with a calculated stockpile life of 10 years. Annual totals will vary <br />according to market demand and may be less or more than projected. <br />The processing area is at approximately 9000 feet elevation and is located on a bluff <br />several hundred feet above the San Miguel River. Therefore, the processing will not <br />disturb any groundwater. The processing operation does not use any water and does need <br />any dewatering. No impacts to existing water rights are anticipated. <br />There is an existing area (approx 8' long x 2' wide) of Canadian thistle along the south <br />fence that will be treated as needed. The buffer area will be inspected monthly to see if <br />thistle and other weeds are emerging. The weeds will be sprayed with a commercially <br />available herbicide such as Spectracide using a 2-1/2 gallon sprayer. <br />Silt fences will be installed and maintained along the north east corner of the permit area <br />where runoff occurs, to treat stormwater runoff and retain silt before it's discharged onto <br />the 7:1 slope outside of the permit area. <br />Revised 5/10/11 <br />
