RECLAMATION PLAN EXHIBIT E (CONT) seeding an area that will just be disturbed later, the applicant suggests a two -tier revegetation plan that is triggered if the reservoir owner plans to start development of a reservoir cell within 6 months of final resoiling. 1) If the reservoir owner plans to start reservoir development within 6 months of final resoiling no grass will be planted. Reclamation will be considered complete if a notarized release letter from the owner is filed with the Division. 2) If the reservoir owner does not start reservoir development within 6 months of final resoiling the area will be planted. However, if at anytime after planting is complete but before final release is granted, the owner decides to begin devel- opment, then reclamation will be considered complete if a notarized release letter from the owner is filed with the Division. The Hill /Oakley and Fort Lupton East Phases have reached this point. City of Aurora has agreed that significant reclama- tion has been met under the contract but L.G. Everist, Inc. has not received a notice that they plan to begin final development. Under this proposed plan, L.G. Everist will seed the above -water level areas by mid - summer, unless City of Aurora provides them the notarized notice, in which case no seeding will be done. The following seed mix will replace the three currently approved. It is more cost - effective to use one seed mix for the entire area. This mix will place approximately 41.2 seeds per pound per sq -ft as prescribed by the NRCS planting guidelines. PROPOSED SEED MIX Species Lbs.

Approximately 31% 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 soil stockpiles around the setback /perimeter of the mined area or replacing soil on a fin- ished slope as it is removed from the next area is designed to minimize the effect of mid -plan stoppage. This will place the 10
