1 <br />1 <br />1 <br />' Since this resource is mainly useful 1n construction pro~ecte, <br />the Upland area will be managed on a ,]ob by fob basis. <br />Contractors will utilize the area to supply material for• specific <br />' fobs. Each fob would involve mining for a few months to a Pew <br />years. We anticipate that these contractors will bring in <br />portable screens and other equipment. The actual nrYning itself <br />' will be contained in an area from five acr-es to ten acres. We <br />have proposed three diPfer•ent locations for• pr•ocessing site <br />setups of a more permanent nature for• substantial ,lobs. We would <br />' expect only one of the Upland processing sites to be used at any <br />given time. These Upland sites are contained within eight to ten <br />acres antl include processing equipment, asphalt plant, recycling <br />cr•ueher•, and fuel storage. Refer to figure D-1. <br />' The general method of minino in the Upland area will proceed as <br />follows: <br />' 1. A front loader will skim off the t.~p six inch topsoil layer <br />and stockpile it. <br />' c. A level area will be created for• the setup of the screening <br />plant and the product stockpiles. <br />3. Mining will tiepin by excavation with a front end loaders. <br />4. Oozer•s may 6e used to move more substantial amounts of clay <br />' if they arse encountered. <br />5. The screening plant will be moved along with the mining to <br />minimize the fr•unt load er• travel distance. <br />' E. fte~ect materials and clays will be r-etur•ned to the mined out <br />area to an aver•aoe depth oY two Yeet. <br />7. The size of these Upland ar-eas will vary between five and <br />ten acres. <br />' Figure D-c shows the entrance signs to be installed at the <br />northeast corn er• of Section 11. <br />' LowlantY Wet iii-ea <br />' Within the Coal Creek bed itself, the sand material is cleaners <br />antl of larger size. The mining area will be ser•v ed by existing <br />roacls which parallel the Creek on the east and west Sides. As <br />you can see by the mining plan, approximately 6~~ of the trees <br />' wi 1l be pr-eser-ved. <br />The prefer-r•ed mining method will be by suction dredge ors <br />' dragline. The operators will st ar•t at some point along the Creek. <br />and mine downstr-eanr in orders to car^r•y a pool of water with the <br />mining. We anticipate that the mining oper•ator•s here will wash <br />much of this sand. <br />1 <br />1 <br />D - £ <br />
