• <br />EXHIBIT E <br />RECLAMATION PLAN <br />In quarrying dolomite or limestone below the present floor level of the old CF&I <br />quarry, [he following reclamation procedures will be followed: <br />The area where a quarry will likely be located is either covered with broken rock <br />overburden material (dolomite and dolomitic limestone) or sized limestone in a stockpile <br />placed by CF&I, or the rock to be moved is lying undisturbed. In neither case is there <br />any evidence of vegetation or vegetation supporting material (soil) on the surface of the <br />area to be disturbed (affected land). Therefore there is no topsoil activity that must be <br />conducted. <br />All the overburden that must be removed will be returned to the "quarry hole". <br />The overall overburden to limestone ratio (waste/ore ratio) will be about .95:1. Therefore <br />95 tons of limestone will be removed for every 100 tons of overburden removed. Or 95 <br />tons of limestone will be removed for every 195 tons total material to be removed. The <br />expected "swell" of the overburden to be placed back into the quarry pit is about 75 <br />percent (See Mining Engineers Handbook, 3~d edition, page 5-03, by Robert Peele). <br />Therefore the final "void" will be 35% of the original excavation. Thus the final <br />excavation will not be anywhere near the size of the quarry as excavated. <br />~.._ <br />The ~ni i overburden will be stockpiled in a convenient location on the permitted <br />area. After about 200,000 tons of limestone is removed from the quarry there will be <br />sufficient "working" room to start replacing the overburden back into the quarry as it is <br />removed without having to place the overburden in a temporary stockpile. The timing of <br />when 200,000 tons of limestone will be quamed is uncertain, but it should be somewhere <br />between 2 and 5 years after quarrying is commenced. <br />The mining plan is to excavate the overburden and limestone with 50' high <br />benches (highwalls) with an 80-degree slope and leaving 25' wide final benches between <br />highwalls. The reclamation plan is to replace the overburden material clear to the top of <br />excavation on all sides except the mountainside of the excavation, and then sloping the <br />fill dowmvard toward the mountain and toward the center of the excavation from the ends <br />of the quarry. No part of the final fill slope will be steeper than 20 percent (5 horizontal: <br />l vertical), nor will there be any remaining highwalls. There will be a depression sloping <br />to the natural dip slope of the mountain in-place rock. Based on current observations at <br />Monarch, it is not expected that the remaining depression will have water in it much of <br />the time, but there could be standing water in the final depression during [he spring of the <br />year when snow melt occurs. A generalized cross-section of the final reclaimed pit is <br />shown on a next page. <br />
