<br /> <br />5~ V. EXHIBIT E -RECLAMATION PLAN NARRATIVE <br />5-Ol. GENERAL <br />Reclamation is the process of initiating and accelerating the natural trend toward recovery of disturbed land <br />areas. The existing land use in the vicinity of the Morrison Quarry consists primarily of open space, ranching <br />and use by wildlife. The operator has substantially completed sustained reclamation of portions of the old <br />North Quatry area and part of the upper west side of the Central Quatry as wildlife habitat which was the <br />undisturbed land use prior to mining on the permit site. This experience has helped to refine a reclamation <br />process which is adaptable to the land use and local climatological factors. The more recent reclamation <br />experience in the Central Quarry has resulted in a plan to better reclaim upper portions of the west ends of the <br />old North Quarry and the planned South Quarry to improve visual impacts of mining at the site. <br />Mining of [he quarry will be accomplished as described in Exhibit D, Mining Plan. The final mine <br />configuration will include mining of the uppermost benches on the west and north sides of the North Quarry <br />with 40 ft highwalls and 40 to 60 ft benches. Additionally, a fill slope will be constructed in the southwest <br />comer of the North Quarry. Upper portions of the west and north sides of the North Quarry, as well as the west <br />side of the South Quarry, will be mined to 40 ft highwall and 40 ft to 60 ft bench, and 80 ft highwall and 80 <br />ft bench configurations to allow for placement of additional reclamation backfill to provide enhanced visual <br />reclamation of portions of the quarry that will be visible to surrounding communities as part of the Front Range <br />backdrop. The remaining, less visible, portions of the quarry will be mined with potentially steeper 80 ft <br />highwalls and 40 ft to 80 ft benches where geotechnical conditions allow. Gradual transition zones between <br />adjacent areas with differing highwall and bench configurations will be constructed as necessary. <br />Reclamation will include construction of one temporary and one permanent reservoir [o be conveyed to the <br />'Town of Morrison. The reservoir sites will be in the deepest portions of the Central and North Quarries. In <br />'the Annexation Agreement, they are referred to as Reservoir Sites No. 1 and No. 2, respectively. The <br />maximum proposed pool elevation in the Central Quarry Reservoir is EI.6,485 ft. No specific pool elevation <br />;has been determined at this time for the proposed North Quarry Reservoir, but i[ is anticipated to be between <br />EI. 6,000 ft and 6,050 ft. <br />.Above circumferential access/maintenance roadways surrounding the reservoir sites, benches will be reclaimed <br />by backfill placement, topsoiling, and revegetation. Concurrent reclamation is planned such that, as much as <br />is practical, revegetation of upper benches will occur prior to opening lower benches that expose them. <br />.Reclamation will follow excavation downward with a general lag of about three to five benches between active <br />mining and reclamation activities. This exhibit describes the plan for the reclamation of the quarry during and <br />after mining specifically describing the overburden/topsoil placement procedures, grading, revegetation, <br />schedule and post-restoration management. <br />c:weaECrs~zoxmaonr~snnsFxoos.rxr V - l <br />
