Approximately 7000 ~.w cubic yards of topsoil will be stored is a linear berm (550 x 60 ~,b'`~g x 6 feet) for reclamation of cut / sloped banks. Mining of the Phase area (10 to 12 Acres) entails a tracked hoe machine for excavation and placement of the graveley/boulder material into dump trucks for sorting with a grissley and a screening plant to be located on the Phase Site. No overburden material is anticipated to be removed or stockpiled. All of the material, the gravel, sand, large and small cobbles, and also very large boulders (3,5,7 cubic yards each) are all marketable products. Road base material will also to sorted and screened from the excavated material. A concrete batch plant will receive aggregate material transported by dump truck The sand wash plant and stockpile area near the Arkansas River will revive it's material by dump truck. Five interconnecting sand wash retention ponds are located within the affected area of the Sand wash and Stockpile area. These ponds are 100 to 160 feet in length, 30 to 60 feet in width and are three to four feet deep. The Phased mining areas are 10 to 12 acres each. It is eapected that 3 to 5 years will be the duration of each phase/area for mining. The area to be mined is a gravelly-sand-rock cobble material with intermittent large boulders and extends from below the topsoil layer to approximately 40 feet in depth. The material below our mine-able material is a highly compacted glacial/basin fill material. The primary commodities to be mined/excavated are the road base material and the concrete aggregates. The secondary commodities are the decorative rock products derived by screening / sorting of the granite cobbles and the occassional rip/rap and decorative boulders. Our water uses -- The pipelines connecting our spring water source to the Sand Wash Plant and for dust control and ultimate irrigation to replanted cut slopes-- are in complinace with our Water Rights 'xoppers Springs Unit 'A' and 'H' (Szhipit 'G'). No silty or graveley water discharges will occur from our operations into the Arkansas River. No other or adjoining water rights will be affected by our operation.
