3). The sand and gravel deposit will be mined using front end loaders, hydraulic <br />excavators and trucks. <br />Mining will be done in phases starting with Pit #1. Pit #3 will be mined next and trucked <br />to Pit #2 for processing. After mining of Pit #3 has been completed, Pit #2 will be mined <br />next, followed by Pits #4 and #5. Pit #1 will remain open throughout the life of the <br />Permit and be used when hauling is restricted thru the Reid property. Crushing will occur <br />in all the pits except Pit #3. <br />The life of the operation will be from 10 to 14 years. The estimated time period to mine <br />each of the individual pits is as follows: <br />1. Pit #1-10 years <br />2. Pit #3-2 to 3 years. <br />3. Pit #2-3 to 4 years. <br />4. Pit #4-2 to 3 years. <br />5. Pit #5-2 to 3 years. <br />The depth of the topsoil and overburden in the pits vary from less than 6 inches in Pit #4 <br />to 15 feet in Pit #5. The average overburden depth in Pit #3 is 9 feet. The average depth <br />of the gravel deposit in the pits is 25 feet with the underlying material being Mancos <br />Shale. Approximately 1 to 1.5 feet of gravel will be left in the bottom of the pits above <br />the Mancos shale to help prevent additional selenium contamination of the ground water. <br />The primary and only product to be mined is sand and gravel. The sand and gravel will be <br />used for construction aggregate for concrete, asphalt pavement, road base and pipe <br />bedding.
