The reclamation plan calls for returning the disturbed areas, after mining and reclamation, to a land usethatis <br />"general agricultural". This land use is consistent with that found in the surrounding area. <br />The predominant feature of the reclaimed area will be a flat graded area approximately 25 feet below the <br />surrounding undisturbed elevation. A Reclamation Plan Map depicting the configuration of the reclaimed <br />ground surtace can be found in Exhibit F. <br />Reclamation will be conducted in a phased manner and will start in each phase at the time when no further <br />disturbance from the mining activities will occur. In other words, reclamation may happen during the same time <br />as mining activities are occurring in each phase. Since no more than 30 acres will be disturbed atone time. <br />Exceptthe staging area, reclamation efforts will begin prior to and simultaneouslywdhthe next mining phase. <br />The initial reclamation efforts, consisting of sloping and grading began dudng 2001a1ong thewesterly boundary <br />of Phase One. Reclamation will occur on a 12 to 18 month cycle until all mining activities have ceased. <br />BACKFILLING AND GRADING - As each of the extraction have the resource removed, the backfilling and <br />grading activities will commence except for any working gravel faces(s). The stockpiled overburden will be <br />hauled from its storage area adjacent to the mining area by mobile equipment and placed where required to <br />achieve a level topography and properly backfilled slopes. In orderto achieve a "natural" appearancethe side <br />slopes of the extraction they will be re-graded irregular and will range from no steeper than a ratio of 2:1 <br />(horizontal to vertical) to a ratio of 3:1. Approximately 50 percent ofthe total length of the slopeswill begraded <br />to the 2:1 ratio. Backfilling and grading will be done by dozers, and/or, scrapers which will compact and <br />stabilize the overburden material. To insure stability of the slopes, material will be placed in 12 inch lifts. <br />In the event that material delivered to the facility is used in the backfilling and grading operations, the fol lowing <br />procedure will be implemented to insure that the material is clean and inert: <br />1. The individual or company delivering material to the facility is required to sign an affidavit certifying that <br />the material is: clean and inert, the originating source of the material, and the estimatedvolume. Atthe <br />discretion ofthe facility operator, the certification may also include an environmental auddofthesource <br />site prepared by a Colorado Registered Professional Engineer or a Registered Environmental <br />Manager. <br />2. During the stockpiling process, the facility manager, and those individuals who operate the stockpiling <br />equipment, will conduct constantvisualanalysis ofthe delivered material on a truck bytruck basis. At <br />a minimum, the visual evaluation will identify that the soil does not have any hydrocarbon <br />contamination, hazardous substances, or other solid waste. <br />3. In the event that contaminated material is identified, all work in the immediate area will cease and a <br />Colorado Registered Professional Engineer or a Registered Environmental Managerwill be contacted <br />by the facility operator. The listed qualified individual(s) will prepare, supervise and implement a <br />Remediation and Disposal Plan conducted in accordance with the requirements of the governing <br />regulatory agencies. <br />TOPSOIL REPLACEMENT- Topsoil replacement will occur using mobile equipment once all regrading ofthe <br />area disturbed by mining is complete. Topsoil will be replaced to a thickness of at least 8 inches, which is <br />appropriate to establish vegetation communties consistent with the post mine land use. <br />RE-VEGETATION -The intent of the re-vegetation is the establishment of plats communities consistent with the <br />post-mine land use. After topsoil replacement, seed bed preparation and stabilization will be conducted and <br />may include one ofthe following: ripping, disking, harrowing andforfurrowing. Because ofthe phased fashion in <br />which the sfte is mined and reclaimed R will allow for continuous analysis of re-vegetation success. <br />This will allow determining the best type of preparation that should be used. Two separate types of re- <br />
