<br />require a cleared corridor of 8 feet and an additional 8 feet for construction. The pipe <br />racks will have 16-foot-high vehicle clearance in the immediate area of the processing <br />plant and will be placed approximately 18 inches off the ground within the well field. <br />The main header pipe rack will be 8.5 feet wide and a minimum of 3 feet above ground <br />at the top of the rack. The lateral and individual well pipe racks will be 6.5 feet wide <br />and a minimum of 2.5 feet tall. <br />A preliminary piping layout has been developed for the 0-5 year panel. In the 0-5 year <br />panel, the total length of the main header pipe system is estimated to be 8,500 feet. The <br />length of the lateral piping systems is estimated at 6,400 feet, and the individual well <br />piping system is estimated to be 3,900 feet. Therefore, the total disturbed surface area <br />will be approximately 8.3 acres. For the remaining five mining panels in the initial 30 <br />yeazs of mining, disturbed areas will approximate the ratio of the 0-5 year panel piping <br />disturbed area. Piping within each subsequent mining panel will be laid out and <br />constructed in a similar fashion. Piping disturbance for each panel is included in the <br />total panel disturbances in Table D-1. <br />Piping from the individual wells to the lateral lines will be constructed as wells are <br />developed in the two-pass mining sequence (see Section D.5). As wells are retired, this <br />piping will be removed and reused for new wells. The piping from the wells to the <br />lateral lines will be placed on low pipe racks and will generally be constructed along the <br />access roads. <br />The general approach to vegetative clearing for the well field piping will be to remove <br />only that vegetation necessary for access and construction. Low-lying vegetation (e.g., <br />grasses and forbs) will probably remain over much of the corridor, and woody <br />vegetation will remain wherever possible within the construction corridor. Soil <br />disturbance will occur only where local topography requires minor grading <br />adjustments to allow uniform piping and where support pilings are placed. No <br />substantial cut and fill is expected for the well field piping, but some will occur, if <br />necessary. Techniques and equipment used for earthmoving will be similar to those <br />used for drill pads. <br />No well field piping will be located at the Parachute Site because all the mining will <br />occur at the Piceance Site. The pipeline that transports solution and recycled water <br />between the Piceance and Parachute Sites is described in Section D.2.8. <br />D.2.3 Surface Structures and Related Facilities <br />The general arrangements of facilities at the Piceance Site and Parachute Site are <br />illustrated in Figures D-4 and D-5, respectively. The Piceance Site processing facility <br />will be a new development, which includes the initial processing system that prepares <br />the mining fluids for transport via the pipeline to the Parachute Site. The Parachute Site <br />will include both new development and renovation of parts of an existing development <br />D~ <br />
