RECLAMATION PLAN EXHIBIT E (CONT) The reclamation timetable shows the types and amount of land use in each Phase when reclamation is complete. Approximately 12.2% of the area in the permit will not be disturbed by mining, either because it is setbacks around well facilities, gaslines ROW's, along the ditches or areas too small to mine that will be kept in their natural state. As mining progresses, the perimeter slopes will be back- filled and graded at or near 3h to lv as discussed in the MINING PLAN. This will insure that when mining ceases only a minor amount of work will have to be done to finish reclamation in the disturbed area. The placement of the temporary soil stockpiles around the setback/perimeter of the mined area would be thereif needed. Since the area between the liner, the water line and/or top of the armoring will be a graveled surface area, no resoiling will be needed. The graveled surface will mean the above-water- line areas simply have to be shaped and graded. We expect to salvage sufficient topsoil to meet reclamation requirements. Of the 809.0 acres ± in the permit area, only 42.1 acres ± or approximately 5.7% will need resoiling and revegetated and remaining above water gravel surface will cover 146.5 acres or 18.1% of the area to be reclaimed. The remaining area will be reservoir area, covered with water or undisturbed area. Observations at the site show that topsoil on the property has a salvageable depth of 6 to 12 inches, averaging 8 inches except in isolated locations. There appears to be more than adequate soils to meet the demand for this site. Setback areas will not be stripped, and the disturbed areas inside the setbacks will not be resoiled. Gravel surface maintenance roads will be built around each reservoir and left around each gas/oil well where no seeding or resoiling will take place. This will provide room around each well or reservoir to service it as needed by the well or reservoir owners. Some inert fill (as defined in Colorado Department Public Health and Environment regulations) may be imported for recycling and resale or in rare cases for reclamation purposes. On-site generated inert material will be used for bank sloping, buried in bank areas around the lakes or will be recycled/sold. An inert fill Notice and Affidavit are included in the Appendix for this mine. Existing soils in place have been capable of producing a fairly dense cover of irrigated crops and dryland grasses and should be suitable for use when revegetating the areas where seeding will be done. These areas will be returned to at least their present vegetative condition when reclamation is complete. Under normal conditions, the operator will strive for a 30 to 40 percent cover rate on the revegetated areas when reclamation is complete. Under normal weather conditions, an adequate moisture re- serve will be present for establishment of the proposed seed mixture. No irrigation will be used during reclamation since the plan is to establish a vegetation cover that is not dependent on irrigation to survive. L.G.Everist, Inc.
