The reclamaton plan calls for retummg the disturbed areas. after minurg and reclamaton, to a land use that s "general agricultural'. This land use is consstent with that found m the surrounding area Because of the'dry land- nature of the seed mix presented herein, urgatan o1 the disturbed areas Nell not be attempted The predominate feature of the reclaimed area will be a slat graded area approximately 25 feet below the surrounding undisturbed etevatan A Reclamation Plan Map depicting the confguration of the reclaimed ground surface can be found in Exhibil F Reclamation will be conducted in a phased manner and will start in each phase at the time when the sand anrd gravel resource has been depleted. In other words. reclamaton may happen during the same tune as gravel extraction actrvdies are occurring m each phase. Since no more than 30 acres will be disturbed at one lime Except the staging area, reclamation efforts will begin prior to and smultaneousty with the next sand and gravel removal prceess The initial reclamaton eNorts, cons~s6ng of sloping and grading began durng 200tabng the westerly boundary o1 Phase One Reclamatbn will occur on a 12 to 18 month cycle until all miring acUvrtres have ceased BACKFILLING AND GRADING - As each of the extracton have the resource removed, the backliling and grading activities will commence except for any working gravel Iaces(s) The stockpiled overburden will be hauled from its storage area adjacent to the mining area by mobile equipment and placed where regwred to achieve a level topography and properly backfilled slopes In order to achieve a "natural' appearance the side slopes o1 the extraction they well be re-graded irregular and will range from no steeper than a ratio 01 2:1 (hor¢ontal to vertical) to a rata of 3.1 Approwmately 50 percent of the total length of the slopes Nell be graded to the 2'1 rata. Backfdhng and grading will be done by dozers. andlor, scrapers which will compact and stabile the overburden malarial. To insure stability of the slopes, material wilt be placed in 12 rich lifts and compacted to a minimum density of 85 percent In the event that material delivered to the facility is used in the backfilling and grading operatans, the following procedure will be implemented to insure that the material is clean and inert 1, The indivdual or company delivering malertal to the facility is required to sign an affdavtt certdyug that the material is clean and inert. the ongnating source of the material, and the estimated volume. At the drscretbn o1 the facility operator, the certi0cation may also include an BrtvlrOnmental audd of the source sde prepared by a Colorado Registered Professional Engineer or a Registered Environmental Manager. 2 During the stockp~Gng process, the facility manager, and those indivduals who operate the stockpiling equipment, will conduct constant visual analysis of the delivered material on a truck by truck basis, At a minxnum, the visual avaluatton will dentAy that [he soil does not have any hydrocarbon contamnatwn, hazardous substances, or other sold waste. 3 In the event that contaminated material rs denUhed, all work m the ntmediate area will cease and a Colorado Regstered Professorial Engineer w a Registered Environmental Manager will becorttacted by the facility operator The listed quatihed mdrvdual(s) will prepare, supervise and implement a Remediation and Disposal Plan conducted n accordance with the regwrements of the governing regulatory agenaes TOPSOIL REPLACEMENT -Topsoil replacement will occur in a phase by phase manner using mobile egwpment once all re-grading of the area disturbed by mining is complete Topsoil will be replaced to a thickness of at least 8 riches. which is appropriate to establish vegelaton communRres consistent with the post mine land use RE-VEGETATION -The intent o1 the re-vegetation ~s the establishment of plant communNes consstenl wdh the post-mine land use.
