<br /> <br />E X H 2 B I T I~ -- M= N 2 N G F L A N <br />Mininq_ at this si±e has beeun under •a ilc.i permit issu?d in <br />1989. It is hoped that mining can continue for <br />approximately 10 years et the site with the present demand. <br />A special use permit was t,bteined fx'om Pueblo County for 48 <br />acres. Our intention is not to mine the entire 48 acres as <br />some of the land is wetlands that will not be disturbed and <br />some of the land is not feasible to mine because of poor <br />materials. It is estimated that demand for materials from <br />this source will remain to be approximately 50.000 tons per <br />year. <br />Topsoil of the surface layer will be removed to a depth of <br />approximately 6 inches. Temporary stockpiles of topsoil <br />will be seeded with Creasted Wheatgrass at a rate of 5 <br />Lbs./acre PLS i{ they remain in place for over three <br />months. <br />The deposit of useable material varies in thickness from <br />4-10 feet in depth. Mining of the site consists of <br />removing the gravel caps from the tops of the hills. In <br />most cases this will leave a relatively flat area after <br />excavation that should not be prone to erosion. Any <br />natural drainage patterns will be maintained and not sloped <br />any steeper than 3:1. Existing roads and accesses will be <br />userd throughout the life of the pit. An access permit has <br />been obtained from the Highway Department for the change in <br />uses of the access from farm use to use es a pit entrance. <br />Any and ell equipment used in the pit is portable in <br />nature. Operations that will be conducted in the pit will <br />be crushing and from time to time an asphalt plant might be <br />located in the pit. Location of the plant sites will vary <br />es mining progresses. <br />No groundwater will be disturbed by mining operations. No <br />mining will be conducted below groundwater elevation end <br />materials will not be removed within et least two feet <br />above groundwater elevation. All water used at the site <br />fox• pollution controls will be trucked to the site. It <br />wi].1 be purchased from area farmers or towns near the site. <br />Since it is likely that surplus material will be generated <br />// rn the form of natural fines that have limited use it is <br />likely that these fines will be placed approximately 6-12 <br />c inches deep over the disturbed area prior to topsoiling. <br />~ These fines will be stockpiled around the perimeter of the <br />.,disturbed area until reclamation can proceed without <br />ini:erference from pit traffic. <br />
