Banks and Gesso. LLC indicated to facilitate the efficient recovery of sand and gravel. Mining will progress in phases, as described below Prior to commencement of production mining, topsoil will be stripped prior to mining in each phase. The Phase 1 mine area has little to no topsoil. Topsoil recovered in both the Phase 1 and Phase 2 areas will initially be used to build screening berms in fhe two areas along the southern boundary of the permit area with adjacent residences (see Exhibit C-2). Specifically, six-foot high screening berms will be placed along the southeast side of the Phase 36 mining area and along the west side of the Phase 2 mining area. Excess topsoil, including any topsoil recovered in the Phase 3 areas will be transferred to areas undergoing concurrent reclamation. Based on these plans, no significant stockpile footprint will be necessary for topsoil resources. Construction materials will be extracted and moved on-site with excavators, front-end loaders, and off-road haul vehicles. Mining limits will be at least 25 feet from the permit boundary, utility easements and top bank of ditches, and 50 feet from the I-70 right-of- way. Mining limits in the northeast part of the site will be at least 200 feet from the Colorado River. The intent of these setbacks is to ensure the stability of structures in the vicinity throughout the course of mining and reclamation (see Exhibit S for further discussion). Phased Mining and Processing Phase 1 commences with topsoil stripping as needed. Mining will be initiated at the northwest corner of the Phase 1 mining area, creating a sump area for dewatering operations. The sump area is intended to retain pumped water for clarification and eventual discharge, or for controlled re-distribution to wetland areas to maintain soil moisture. Once the sump is operational, as needed, the direction of mining within Phase 1 will generally move south, from the working face nearest the property boundary to the west. The processing plant, including screening and crushers to be used during mining in Phase 1 and 2 will be located in the lower part of the Phase 3 mining area, as shown on the Mining Plan Map (Exhibit C-2). Reclamation will begin in areas within Phase 1 within one year of the completion of this phase of mining. Grand River Park Project 05021 Silt Sand & Gravel LLC 8 May 2006
