Concurrent reclamation is planned for all the pond edges as each excavation/pond <br />footprint area is developed over time. The total planned final exposed water surface <br />area for both ponds is 35.9 acres (Pond #1-19.80 ac. and Pond #2 — 16.10 ac.). <br />Excavation depths may range from 0 to +25 feet below ground level (BOL). Ground <br />water levels are seasonal with a possible upper limit of 1.5 to 3 feet (April —June) and <br />a lower limit of>6 feet BGL. The aggregate mining operations will intercept <br />groundwater at an average depth of 4 to 6 feet BGL depending on the ground level <br />elevation (the site is relatively flat) and the seasonal water table fluctuations. <br />Estimated water surface elevation will average 6l 94 feet AMSL. <br />Aggregate materials will be removed via dragline or excavator from just below <br />the stripped topsoil surface and processed or stockpiled in an adjacent prepared <br />operations area of approximately 3 to 4 acres. The size of any operations area would <br />be dependent on the amount of room needed for any production stockpiles for large <br />volume projects. All operations will be within the pond/excavation footprint areas. <br />All excavated areas within the pond footprint will become a pond water surface or < <br />3:1 sloped pond edge. The final operations area at the site will be an approximate 3 <br />acre area located between the site gate and the southern end of both ponds. This <br />approximate 3 acre area will be the only area requiring reclamation at the completion <br />of site mining activities. All pond edges and perimeter roads will have been <br />completely reclaimed and constructed by the end of final pond excavation. With a 50 <br />foot wide maximum pond perimeter topsoil stockpile/road "halo" or "buffer" area, a <br />total of 9.80 acres will have been concurrently reclaimed. <br />(e) Approximate timetable to describe mining operation; <br />Mining and crushing, screening and asphalt process activities will commence <br />after all State and County Permits have been approved and issued (July 2008) <br />and continue from 5 to 15 years or longer. <br />(f) Narrative describing nature of deposit to be mined and underlying stratum. <br />The soils in the area of the proposed operation area as mapped and described by <br />the U.S.D.A. Soil Conservation Service consists of soils belonging to the <br />following types (Soil Map and Non -Technical Soil Descriptions and Soil Tables <br />are attached to Exhibit I — Soils Information). The soil types are listed in the order <br />of their possible aggregate potentials as indicated in the soil description survey <br />documents and from discussions with the landowner and from description of soil <br />profile in the pit dug for installation of large diameter water supply well from the <br />previous mined and disturbed site areas. Permit area soil types are as follows: <br />WestWater Engineering APPENDIX C - 8 July 2012 <br />
