<br />E X H I H T B <br />MINING PLAN <br />WalFier F'it North will be mined for river-run alluvium, princi- <br />pally sand and fine grave:ts. This mining will be under the terms <br /> of an MLRE 110 Limited Impact Permit. The amount of rr~a er-ial to <br />' be removed annually will he in the range of 1ir,0ir0 ton and will <br /> not e:;ceed 70,000 tons. <br />' The proposed mining area parallels within 100 feet th west to <br /> east bend of Clay Creel::. Flow in Clay Crc:el; is restr' ic{:ed to <br /> runoff from snowmelt and localised convective events. At the <br /> tune of the site investigation it9arch 1, 1984), Clay 'eel:: was <br />' dry. The site will not require an PJPDES permit, as rr~i ~ing will <br /> be a dr-y operation. Th~a area to be ~nir~ed :is a point g avel. bar <br />' deposited by flooding from Clay CreeV:: in 1965. <br /> The proposed operation i•~ a small sand and gravel pit _nd will <br /> not remove any signifir=art a~T~or"rnt of ranGeland from prod rctior~ ar <br />' interfere with grazing nn ^t.her adjacent areas. 7ota1 ar=reaye <br /> will be 9.9 acres, including a .14 acre !caul road. Mi ping ari11 <br /> tale place only during tF~~= riry season. There is no top "il to be <br /> removed at the Walker F'it hJorth. The miring process at this pit <br />' is intermittent and will be used only when substant ial road <br /> repair is required and .a large amount of material is n eded to <br />' maintain the roads. This may ar~ly or_cur one year" in f <br />area one acre in size previously mined lies within the ive. An <br />area of <br /> proposed mining activity. <br />' Mining will be achieved Icy using a front-end loader and loading <br /> directly into dump trucb;s and truc4::ed off site. rher _ is na <br /> topsoil to remove. l"he gravel deposits are appro::imate:l lt~ feet <br /> deep. Groi.rndwater occurs .at a depth of 1.-15 feet and wi ll rout be <br />' affected. Mining will proceed in a north to south d irection. <br /> Some screening of the gravel will be required. <br /> <br /> <br />1 <br /> <br /> <br /> <br /> r~-1 <br /> <br />
