be salvaged and stockpiled on the west and north sides of each new lift to be spread on <br />the remaining slopes after gravel extraction and final grading. <br />It is not possible to determine a fixed location for any mobile crushing, screening, asphalt <br />production or other process equipment that may be used at the site from time to time. <br />Equipment will be located by the equipment operator and/or contractor near the working <br />face of the mine upon arrival and removed when processing for the season or a <br />particular project has been completed. Any stockpiles located within the permit <br />boundary will vary in location as best benefits the operator. Generally product stockpiles <br />will be located in [he active excavation area or in areas along [he haul road. <br />Maximum High wall dimensions along excavated lifts benches will be 20 feet vertical by <br />200 lineal feet, unsloped at any one time, and will no[ encroach on permit boundaries any <br />closer than needed [o establish slopes compatible with [he surrounding terrain by dozing <br />to match [he surrounding topography. A dozer will be used to push material from above <br />in areas where the deposit is thicker than 20 feet so that unstable and unsafe high-walls <br />of over 20 fee[ are not created. Any high-wall along [he north boundary edge of the <br />permit area will be reduced and sloped to match the topography as [he mining proceeds <br />to the east so that no more than 200 feet of exposed high-wall will be present at any <br />one time. The mined area will day-light and be visible from [o [he east only during <br />and upon the completion of mining operations. No impoundments or waste dispose! <br />areas are anticipated. <br />(e) Approximate timetable to describe mining operation; <br />Mining and crushing activities will commence after all State and County Permits have been <br />approved and issued (Summer 2005) and continue on an as needed basis until all gravel has <br />been removed from the permitted area. The proposed access and haul road will be <br />constructed into [he Phase I "initial area of operations" on the west/northwest side of the site. <br />Mining will then progress to the south and east of [he Phase I area. The entire Phase I area <br />will be mined and reclaimed prior to moving into the Phase 2 area. The Phase 2 area will <br />generally be mined along the ridges in an easterly direction. It is estimated that mining <br />activities at the site will be for a period of20 to 50 years. <br />(t) Narrative describing nature of deposit to be mined and underlying stratum. <br />The nature of the gravel deposit at the proposed permit area for the Gmy Pit # 2 is a large <br />north/south trending ridge on the west with smaller gravel ridges fingering off towards the <br />east. The ridges are covered by cedar pinion and sagebrush. The gravel/cobble deposits tie <br />above the Mancos Shale/weathered shale in thicknesses from a few to greater than 50 feet. <br />Soil/topsoil occurs intermittently across the site from 0 to 60 inches and there is no distinctive <br />overburden between [he soil and the gravel deposit. Slopes are steep to very steep (greater <br />than I S%). Operations at the site will begin at the top of the westem ridge conducting facial <br />extraction of the gravel deposits off the slope in approximately 20 foot lifts following the <br />existing site topography. Topsoil stripped from the initial area of operations will be <br />stockpiled in the west and north 50 foot perimeter buffer zones. The gravel deposits are <br />greater in thickness on the north and west and thin towards [he east and south, As each lift is <br />completed, [he slopes will be graded to match the surrounding topography leaving a gradual <br />slope from west to east along the east flank of the large north/south trending ridge. <br />The site as mapped and described by the U.S.D. A. Soil Conservation Service report of June 4, <br />2001, consists of eroded stream terraces with a skeletal overburden of soil. Soils on the site <br />range from 0 [0 60 inches and are described as Steep Shallow Clay Loam P.J. Gravel/cobble <br />till deposits underlie the surface soils from a few feet to over 50 feet in thickness along the <br />large western north/south trending ridge.
