boundary. The powerline and telephone cable are separated from the proposed operation by <br />Routt County Road 53. See Map 2, Existing Conditions, for approximate locations. <br />(h) Soils Information <br />See Exhibit I — Soils Information <br />6.4.4 EXHIBIT D — Mining Plan <br />(a) Method of Mining <br />The mining method will be primarily a truck/shovel/dozer operation. The red rock will be <br />excavated using dozers and track/backhoes. The excavated material will be loaded into road <br />legal trucks with a front -end loader or stockpiled until needed at a later date. Some of the <br />material, depending on the use, would be crushed and stockpiled. The final excavated slopes <br />will be approximately 1H: 1 V with a flat bench at the base of the slope extending to the <br />County Road. <br />The previously mined area in the original Routt County permit will be use as a staging and <br />storage area for the initial operation. The layout of the operation is shown on Map 3, Mine <br />Plan Map (see Attachment 3). <br />(b) Earthmoving <br />Vegetation and topsoil, where present, will be removed. The available and salvageable <br />topsoil will be stockpiled for future replacement. <br />(c) All water diversions and impoundments <br />No surface or ground water is expected to be encountered during the mining operations, <br />therefore no impoundments will needed. Surface water from storm events will be controlled <br />with ditches and small sumps placed as needed. <br />(d) Size of area to be worked at any one time <br />As shown on Map 3, Mine Plan Map, the area is divided into three (3) phases totaling <br />approximately 23.3 acres. Each phase of the operation varies in size from; Phase 1 — 8.3 <br />acres, Phase 2 — 8.6 acres, and Phase 3 - 6.5 acres. <br />Access to each phase will be restricted to a designated gated entry. This gated entry will <br />move from phase to phase as required for access by trucks and equipment. The gated entry <br />will restrict access by the general public. <br />(e) Timetable <br />Startup is scheduled for Spring 2011. The timetable for completion of each phase is <br />dependant on gravel needs by Sage Creek Coal Company and Routt County Road and <br />Bridge Department. The periods of operation are expected to occur between the months of <br />May and November. <br />2 01/2011 <br />
