2.0 - Site Description and Map <br />The affected area is located in the N/2 of Section 18, T12S, R74W, on a 66.80 <br />acre site - DRM&S Permit # M-1984-101 TR2. This SWMP is for mining and <br />process activities at the site. A previously mined Phase 1 area on the east side of the <br />permit area is at a topographic low and all site stormwaters can and will be directed <br />and contained at this location if not contained in active excavation areas of the mine <br />site. (Map attached). All site stormwaters are contained within the permit area in the <br />excavated areas or ultimately at the southeast sedimentation area. <br />Depending on local needs and market conditions, mining and processing for road <br />base, fill material and asphalt pavement may take from 10 to 15 years or longer. <br />Aggregate processing (screening and crushing), temporally permitted asphalt <br />production (via Park County CUP for life of mine area) and material stockpiling <br />operations may be temporally located at the site from time to time. Portable mobile <br />process equipment for crushing, screening and concrete/ asphalt production (Park <br />County CUP for life of mine) will be mobilized as necessary and will have all <br />necessary construction and air permits for such equipment. <br />All disturbed areas will be eventually be reclaimed to rangeland. Annual <br />reclamation is planned for mined and stockpile areas depending on available space <br />and time of season. No wet-lands, or other water resources will be affected by the site <br />activities. All stormwater will be contained under the site SWMP and general <br />Stormwater Permit to the excavated areas. Ditching, silt fencing, berms, bales and <br />other site stormwater BMP's will be used as part of site stormwater controls. <br />Aggregate materials will be removed via dragline or excavator. Topsoil is <br />temporally stockpiled around perimeter of the area for use in the planned reclamation <br />and for any 3:1 bank slopes. Any and all topsoil found within the site will be <br />stockpiled as described above for use in site reclamation. Disturbance will be minimal <br />to the adjacent remaining pasture areas out-side the excavation areas until mine <br />activities move to those areas. The planned site reclamation will provide additional <br />wildlife habitat within the S. Platte River Basin corridor
