EXHIBIT E Reclamation Plan This plan covers the proposed 5J Pit reclamation plan. Final Proposed Land Use The current land use for the 5J Pit property consists of general agriculture; cultivated dryland grasses and other areas previously disturbed by the property owner. The use of this land is not expected to change. Properties surrounding the proposed 5J Pit site are primarily rural agricultural with some areas of historic aggregate mining. Transportation rights-of-way (ROWs) also dominate the area immediately adjacent to the property with the Interstate 25 (I-25) ROW east of the proposed site and the Burlington Northern Railroad ROW to the west. With so much open, undeveloped land in the surrounding area, maintaining this land as general agriculture is consistent with the more regional land uses. General Overview of the Reclamation Plan Reclamation of the proposed permit area is fairly straightforward. Much of the pit, after mining, will contain a gently sloping pit floor that allows stormwater to infiltrate or runoff toward the drainage swale adjacent to the Burlington Northern Railroad ROW. The pit floor will be blended into the adjacent property and will be connected to existing drainages. Reclaimed mine pit side slopes will be created from backfill with overburden. All areas disturbed by mining activities will be prepared with overburden and topsoil and revegetated during reclamation. Revegetation will generate a blend of grass species and, given suitable precipitation, should produce good vegetation cover over much of the reclaimed site. In general, shallower reclaimed slopes will provide easier access during reclamation and safer access for agricultural equipment following mining. Shallower slopes will also aid in establishing vegetation growth and minimize erosion. Although pit side slopes will be backfilled and graded to blend into the adjacent topography, no slopes will be reclaimed any steeper than 3H:1 V. Grading of pit side slopes and the pit bottom will attempt to adhere to the surrounding natural drainage patterns. Roads not necessary for future access and other disturbed areas will be reclaimed with overburden and topsoil replacement and vegetative cover to stabilize the areas and minimize erosion. Reclamation Measures/Materials Handling On-site topsoil and overburden material will be used for reclamation as needed. Similar to mining, earth moving equipment may include, but are not limited to dozers, loaders, scrapers, and excavators. Additional farm equipment for grading and seeding may be used for revegetation activities. 51 Pit DRMS 112 Permit Application Page 10
