Exhibit E Reclamation Plan (cont) RIVERSIDE SEEDMIX (REVISED 2018) Species # PLS/Acre Switchgrass Greenville or Neb 28 1 . 00 Sideoats Grama Vaughn or Butte 2 . 00 Little Bluestem Pastura 3 . 50 Sand Bluestem Elida 3 . 00 Western Wheatgrass Arriba 3 . 00 Per ac . Total 12 . 50 The trees originally proposed have planted and partially died over the years in Lake Marjorie and Lake Robert areas . They will not be replanted. There was no tree planting proposed on the west lake area and none are planned in this amendment . The added area has no trees on it at this time, since it was used as feedlot . The landowners may wish to plant them at their risk, but the operator does not want the liability of having to have a certain number growing to complete final release on the permit . AMENDMENT 6 - Lake Robert Changes In the Technical Revision filed on 7/24/2015 the final disposition of Lake Robert was left open ended for 5 years due to the uncertainty of what would happen if the South Platte River continued to flood the area . Over the past three years there has been no flooding and the area backfilled by the river continues to support grasses and cottonwood seedlings that have been naturally transported to that area . It is very similar to other sandbars or river scour areas that naturally reclaim themselves between periods of flooding in this area . It is now appropriate to address the revision that was anticipated in 2015 since that would have required an amendment anyway. The proposed change is to leave the backfilled area as flood channel with no additional reclamation to be done on it since it may flood in the future . If this flooding occurs it is likely that the backfill area will increase and the lake area will be reduces so once Lake Robert is revegetated, as-built maps will be filed with the Division. The old lake bank slopes from the original ground surface to the water surface and top of the backfilled area will be slope to 3h to 1 or less and revegetated as approved in the current plan. The armored outlet on the north shore of Lake Robert will remain in place to protect the area if flooding occurs in the future . Much of the Lake Robert area was reclaimed prior to the flood. The northern end of the area around the lake area is well revegetated and may need no further work, the parking area will need grading and the concrete pad will remain. The road over the south inlet channel has been rebuilt to provide access to the powerlines on the east side of the mine . It was built to control minor inflow into the backfilled area but during another large flood will most likely be washed out . 11
