pipe rack network. The extent of land disturbance within each mining panel will not be total, but it will be significant. Staged reclamation of the well field as solution mining panels are retired will minimize the size of the disturbance area at any given time throughout the project life. As individual solution mining wells are retired they will be stabilized using suitable interim- stabiliza[ion techniques, as described in The Plan, to prevent erosion until final reclamation of all or part of that specific mining panel is undertaken. Roads that will not be needed to serve subsequent development within the mining panel will be similarly stabilized. Each well pad will be contemporaneously reclaimed after it is permanently retired. Interim stability techniques will be used only on areas that will be redisturbed. Final reclamation of each mining panel or part of a mining panel can only be accomplished once mining activities in [he panel or part of a panel have been concluded. At that point, the solution mining wells will have been properly abandoned, [he solution collector pipes, pipe racks, electrical panels, and pumps will be removed to serve other areas, and the well field access roads can be abandoned as appropriate. Final reclamation would immediately follow the completion of abandonment and decommissioning activities. At any time, the disturbed arca in the well field will roughly approximate the size of one of the mining panels. The amount of land expected to be substantially disturbed within a mining panel conservatively ranges from 125 acres to 209 acres and averages about 172 acres. Actua! physical disturbance and clearing will likely be less. 2.2.2 Surface Facilities American Soda anticipates operating the Yankee Gulch Project indefinitely (Steigers Corporation, 1998). Therefore, most of the surface facilities outside the mining panels will function long term, and their reclamation would occur in the distant future. Development and operation of the plant site facilities (Piccance Site and Parachute Site) will be in accordance with this document. Five buildings will be locatcd at the Yankee Gulch Project Piceance Site in the initial plant processing area, including the administration, solution processing, pumphouse, heat exchanger and general purpose buildings. Also, an electric substation, a generator, outdoor switch gear, a pipeline feed surge tank. a return water collection tank, a cooling tower and parking lots will be constructed. The Piceance Si[e plan[ will occupy an area about 6.5 acres in size, with access controlled by security fencing. A l3-acre evaporation pond will be located near the processing plant. The Parachute Site will support a processing plant area, which will include process buildings, a storage building, storage tanks, an administrative and laboratory building, product packaging and loadout facilities, utilities, a rail spur, several ponds and other associated facilities. The Parachute Site is associated with an existing inactive industrial facility. As a result, development of the Parachute Site will result in minimal land disturbance. Minor relocation of the existing railroad spur may result in 2 to 3 acres of additional land disturbance. Since these facilities will be operated long-tetra for the life of the project, final reclamation measures are not stipulated in The Plan. These measures will be finalized by American Soda and the appropriate agencies as the project nears completion. However, it is anticipated that general closure and reclamation concepts will be implemented. Facilities will be decommissioned in preparation for removal. Decommissioning will involve disassembly and removal from the site of all salvageable equipment, instrumentation, parts, and supplies. All structures and facilities will be salvaged, if feasible, or demolished. Any non-salvageable AmCnLLI Soda. L.L.P. 2-2 Soil Conurvanon. Emsian and Scdimenl Control.
