RECLAMATION PLAN EXHIBIT E (CONT) topsoil where it will be needed for reclamation and will reduce the distance it has to be hauled for reclamation. Usually, this will mean it simply has to be shaped and graded. We expect to salvage sufficient topsoil to meet reclamation requirements. Of the 897.64 acres ± in the mined area, only 119.72 acres ± or approximately 13% will need resoiling and revegetated. 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, so only the disturbed setbacks and slopes to the lake perimeter will be resoiled. Graveled mainte- nance 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. 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 above water areas. 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. Optional Reclamation Plan. We are submitting two options for final configuration of the reservoir areas as well. Option A - The reservoir configurations for Option A are show on the large map on MAP EXHIBIT F- RECLAMATION PLAN MAP . Option B - The inset map shows the reservoir configura- tions under Option B. The methods used to reclaim the reservoirs will be the same for both options. The difference may be an increase /decrease in the volume of developed water storage and an increase /decrease in the amount of revegetation necessary. We do not know when the Mining Option B or the Reclamation Option B or some part(s) of either or both will be implemented, 1 1
