IV-,. EXHIBIT E Reclamation Plan Design intent The Lafarge Brown property will be mined as part of the West Pit of the Greeley 35th Avenue Pit site. The West Pit will be reclaimed as an open water pond. Excess overburden or portions of the deposit not mined will be used to vary the shape and slopes of the finished unlined pond. Native and adaptive plantings and ground covers will be used to restore and enhance all areas disturbed by mining activities. This reclamation plan was developed based on: • A thorough evaluation of the environmental resources and existing conditions on and adjacent to the property; • The context of the property relative to existing and planned land uses in the area; • The volume, depth and configuration of the mineral resource; • The landowners' plans for the property; and • The rules and policies of the City of Greeley, the Colorado Division of Minerals and Geology and other applicable local, State and Federal agencies. Key considerations include the following: • The Cache la Poudre riparian corridor borders the northwest side of the Lafarge Brown property. The corridor has been left out of the permit boundary adjacent to the Lafarge Brown Property. • The open water pond which will be created upon reclamation of the Lafarge Brown property may provide some wildlife habitat due to its proximity to the river corridor. Post-Mining Land Use Following the mining of the Lafarge Brown property, the land will be reclaimed to be part of the open water pond planned for the West Pit. All disturbed areas around the perimeter of the mined area will be revegetated with a native seed mix, as recommended by the Soil Conservation Service (recommended seed mixes below). This use is compatible with the surrounding land uses and with the City of Greeley planning goals. Lafarge will concurrently reclaim mine walls where mining has been completed according to the Mine Plan. Reclamation, including re-grading and seeding, will be completed within two to five years following the completion of mining or filling operations. The mining and reclamation will leave no high walls on the property. No acid forming or toxic materials will be used or encountered in the mining. There will be no auger holes, adits, or shafts left on the site. Topsoiling Topsoils in the proposed mine areas are Aquolls, Aquents, and Fort Collins loam. All suitable soil material will be salvaged for topsoil replacement. Topsoil will be replaced, where required, in reclaimed areas at a depth of approximately six to twelve inches. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1).
