' effective downward-percolating sail-moisture reservoir, if you <br />i <br />I~ will, a limiting layer, t^ reduce irrigation and soil moisture <br />lasses to bacE:filled tailings. Until trench is opened {late <br />1984) this will be the a„tent of reclamation for trenches 1 and <br />_. When trench is opened, approximately ~'2,C~~~~~ cubic yards of <br />plant growth material will be available for topsoiling (soil map <br />' unit GO>. <br />' All grading of the bacl::filled tailings will be done before <br />the mine-soil intermediate-layer is placed. Nine soil will be <br />' dumped and graded to conform to the postmining land farm (sheet <br />' ? of 4) planned. Topsoil removed from trench 1, will be <br />stocl::piled on the Fhase II area and not disturbed until final <br />' reclamation of the first trench in F'hase II because these soils <br />will be very similar to the native soils removed in Phase III of <br />' the mining sequence. The plant-growth medium ta4:en from above <br />' trench (sail GO) will be placed and final graded to a depth of <br />2 faet aver the entire 1~ acres of trench 1 in the first year. <br />' There will be no highwalls left and no to::ic materials e;;ist <br />within the overburden, tailings, mine sails, or topsoils. <br />' Water: No disturbance will occur to the prevailing <br />hydrologic balance. Water quality is not e::pected to be affected <br />due to the fact that there is no gro~_ind-water table e::pected <br />' w~.thin ~~~~~ feet and the geologic formations are not F::nown to be <br />aquifers. Surface-water quality will not be affected. At <br />t present what runoff does occur is impounded in seasonally dry <br />' ponds. These ponds have acted as sediment catchments (photo 18) <br />ire past mining operations and will continue to be used as such <br />8 <br />
