2.0 - Site Description and Map <br />The affected area is located within the NE/4 of Section 3, T6N, R9OW. 'The only <br />areas that will require seeding will be the pond edges and some pasture immediately <br />adjacent to the pond edges. All operations will he within the excavation/pond <br />footprint and disturbed areas will be reclaimed as water surfaces. Some small <br />waterfowl nesting islands and irregular pond shorelines will he developed as part of <br />the site reclamation to encourage more diverse habitat. There will be no site activities <br />involving the Yarnpa River. <br />All areas of the site are currently classified as Pasture. All disturbed areas will be <br />reclaimed to developed water resources (2 pond areas). No wet -lands, or other water <br />resources will be affected by the site activities. All stormwater will be contained <br />under the site SWMP and general Stormwater Permit to the excavated areas. <br />Ditching, silt fencing, berms, bales and other site stormwater BMI'"s will be used as <br />part of site stormwater controls. <br />The mine area, as shown on the map, totals approximately 62 acres. All site mining, <br />processing and temporary stockpiling will be within the excavation footprint of the <br />planned ponds. Each pond will be required to have a gravel pit well permit and any <br />excavation/pond edges will be a minimum of 100 feet from the Yarnpa River as per <br />the Colorado Division of Water Resources District Engineer. Mining activities may <br />take place in any of the 2 pond footprint areas at any time in order to establish the <br />initial 2 separate water surfaces for stormwater control and dewatering. Concurrent <br />reclamation is planned for all the pond edges as each excavation footprint area is <br />developed over time. <br />Aggregate materials will be removed via dragline or excavator. Topsoil will be <br />removed from and temporally stockpiled around the pond footprint limits for use in <br />the planned concurrent pond edge reclamation and for any 3:1 bank slope <br />stabilization to 10 feet below the average water surface elevation. Pond footprint <br />areas that will be used for material processing and stockpiles will eventually be <br />excavated and developed to water surfaces as the pond areas expand to the planned <br />area limits. Any and all topsoil found within the excavation/pond footprints at the site <br />will be stripped (as necessary) and stockpiled as described above for use in site <br />reclamation. Disturbance will be minimal to the adjacent remaining pasture areas out- <br />side the excavation footprints. The planned site reclamation will provide additional <br />wildlife habitat within the Yampa River Basin corridor <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 />Limited screening and crushing, asphalt production 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 asphalt production will be mobilized <br />as necessary and will have all necessary construction and air permits for such <br />equipment. <br />WestWater Engineering APPENDIX C - 26 July 2012 <br />
