<br />• DIVISION OF MINERALS & GEOLOGY BOARD PERMIT APPLiCAT]ON <br />REGULAR OPEKAI'ION 1112) <br />PROJECT NAME: HOGUE/RIVER PIT <br />I' a e c ., <br />EXHIBIT D - MINING PLAN <br />Initial mining operations will commence at the existing <br />pond area and move westerly. This will utilize the <br />remaining gravel reserves in this area. As these reserves <br />are exhausted, mining operations will expand to the west. <br />Topsoil will be stripped ahead of mining operations. It <br />may be possible to strip topsoil in association with actual <br />mining operations. If this method is feasible, very little <br />area will be reyuired to be disturbed prior to actual <br />mining operations. If this method is not feasible, an area <br />niay require topsoil removal prior to gravel extraction. <br />However, due to the depth of existing gravel reserves, only <br />a small area will be reyuired to be stripped prior Co <br />mining. It is estimated that a maximum of two acres would <br />be stripped of topsoil prior to actual gravel extraction. <br />Actual area to be mined in Phase I is approximately S.0 <br />acres. <br />• A small area will be stripped on the south side of the <br />existing pond for dewatering operations and construction of <br />a settling pond. Less than one acre will be required for <br />the dewatering system, which would include the settling <br />pond and trenches. <br />As the pit excavation expands westerly during Phase I <br />operations, irrigation water will be redirected along the <br />northwest and west boundaries of the pit excavation. <br />By utilizing the gravel reserves in the existing pond area <br />first, overburden will not be evident - having been removed <br />during previous mining operations. Some unsuitable <br />material may be encountered during this stage of Phase I, <br />although this is not anticipated. If unsuitable material <br />is encountered during mining in the pond area, it will be <br />stockpiled in an area stripped of topsoil. This material <br />will be placed back in the pit excavation once there is <br />sufficient area. After the existing pond area is <br />sufficiently mined, overburden and unsuitable material <br />encountered during pit expansion will be transported <br />directly to backfill areas. <br />• <br />Duckc:ls Construction, Inc. dba Yampa Aggregates <br />41230 Routt County Rd. #129, Steamboat Springs, Colorado 80487 <br />
