<br />Initial work in each phase will be improvements to existing fencing and installation of new fencing
<br />as needed, slurry wall construction (Cooley Reservoir area only), topsoil and overburden excavation
<br />and stockpiling, and dewatering trench excavation (Cooley Reservoir side only). Slurry wall
<br />construction on the Cooley Reservoir side will consist of a standard soil-bentonite slurry wall a
<br />minimum of 2' in width to form an continuous circumferential wall around the area to be mined, prior
<br />to mining. Sepazate slurry walls will dither be installed around Phases 2 and 3, or around Phases 2,
<br />3, and 4 as one continuous slurry wall, if PSCo. permission is obtained to cross the power line right-
<br />of--way in two places. Generally it is expected that the slu wall will utilize a combination of on-site
<br />overburden material and imported soil- entonite material. Dewatering trench excavation will be
<br />performed with an excavator into the underlying claystone bedrock. Trench sidewails in bedrock will
<br />be excavated vertically to several into the bedrock, and trenches will be constructed to develop flow
<br />discharge locations and minimize evaporative Iosses.l~Frrotiti~.walree; will draia,>tr~,

<br />Equipment that will be used on site include loaders, scrapers, backhoes, dozers, excavators, water
<br />trucks, end dump and belly dump trucks, and other miscellaneous vehicles. Field conveyors, hoppers,
<br />and transfer points will be utilized to provide conveyance to the Plant Site area. On the Fulton
<br />Wildlife Area side, trucks may also be utilized to convey material to the Plant Site. Direct export of ~,~[
<br />borrow material may also be undertaken from the designated access points. Export of all processed /T~' -/ !
<br />material will occur from the Plant Site from a new entrance to be constructed onto Brighton Road. n'`~"~
<br />Improvements at this new entrance and on other adjacent roads will be in accordance with approvals n -+
<br />from CDOT and the Adams County Department of Public Work. The Plant Site's entrance from o~`t~
<br />100' Avenue will be utilized for traffic for employee, visitors, etc. The narrative portion of the ~"~
<br />Traffic Impact Report prepared by Leigh, Scott, & Clearly, which discussed traffic generation from
<br />the facility and proposed improvements, is included at the end of this submittal.
<br />Mining hase~s are described on the next several pages. Mining will create''/H to 1 V excavation
<br />s ope` I s. Finat slopes will be reclaimed to 3H:1 V slopes from ground level to the depth of the
<br />excavation. Except for Phase 1B, reclamation will be concurrent with mining, as backfilling o~~
<br />overburden and topsoil, grading, and planting will follow the mining operation in each phase. Exhibi y
<br />E, Reclamation Plan, and Exhibit F, Reclamation Plan Map, provide details of site reclamation, which ~
<br />in general consists of backfilling, regrading, planting (above water line), and armoring the upper
<br />reservoir slopes for wave resistance. ~,~ ~,
