<br /> <br />• DIVISION OF MINERALS & GEOLOGY BOARD PERMIT APPLICA"PION <br />REGULAR OPERATION (112) <br />PROJECT NAME: HOGUE/RIVER PIT <br />Page 2 <br />EXtiIF~IT D - MINING PLAN <br />_. Overburden stripping is anticipated to be minimal due to <br />the close proximity of the gravel reserves to the ground <br />surface. Any material unsuitable Tor topsoil will be <br />hauled to previously mined areas and utilized on the back- <br />fill operations. This material may also be used to flatten <br />pit shorelines. <br />4. Exploratory tests have indicated that the thickness of <br />gravel deposits to be mined vary from 21 feet on the south <br />side of the project to 47 feet on the north side of the <br />project. Bedrock lays directly underneath the existing <br />gravel reserves. Gravels will be removed to bedrock or to <br />levels that permit feasible economic recoverability. <br />_`. The proposed main access to the site will be at milepost <br />126.2 (approximately) on U.S. Highway 40. Interior <br />• accesses are as described in the mining plan maps. <br />E.. Due to the low lying nature of the area, close proximity to <br />the Yampa River, and existing water in the pond area, it is <br />anticipated that the water table will be from three feet to <br />six feet from the existing ground elevation. <br />C. General Mining Methods and Operations <br />Approximately 12" to 24" of topsoil exists in the project <br />area. Approximately 12" of topsoil will be stripped from <br />mining areas and stockpiled as shown on the attached map. <br />Topsoil from Phase I will be stockpiled along the north and <br />northwest limits of Phase I operations. As mining <br />progresses, topsoil from stripping will be hauled directly <br />to the previously mined areas and used to reclaim these <br />areas. Additional stockpiles may be handled separately. <br />It is anticipated Chat wetland topsoil will be transported <br />directly to wetland replacement areas. <br />,• <br />Duckels Construction, Inc. dba Yampa Aggregates <br />41230 Routt County Rd. #129, Steamboat Springs, Colorado 80487 <br />
